[0004] With the rapid development of science and technology, electricity has become an indispensable energy source for people's production and daily life. To ensure the smooth supply of electricity and the normal operation of production and life, energy storage devices are needed. Energy storage devices are devices that cyclically store and release electrical energy. By charging or discharging the energy storage device, electrical energy is stored in the energy storage device or supplied to electrical devices. Energy storage devices are widely used in industrial power supply, household power supply, temporary power supply, mobile power supply, wind power generation, solar power generation, and energy storage power stations.

[0005] In the development of energy storage devices, in addition to improving their performance, reducing their operating costs is also an important issue that cannot be ignored. Therefore, reducing the operating costs of energy storage devices is a technical issue that requires continuous improvement in energy storage technology.

[0006] Summary of the Invention

[0007] The present application provides a container, an energy storage device, an energy storage system, and a charging network, which can reduce the cost of using the energy storage device.

[0008] In a first aspect, an embodiment of the present application provides an energy storage device, which includes a container and a control compartment. There are m containers, m ≥ 2, and the m containers are arranged along the height direction of the container. The container includes a box body and battery cells. There are multiple battery cells, and the multiple battery cells are housed in the box body. The control compartment includes a compartment body, a control module, and a thermal management module. The control module and the thermal management module are housed in the compartment body. The control module and the thermal management module are both connected to the container. The control module is used to electrically control the battery cells, and the thermal management module is used to manage the temperature of the battery cells. The dimensions of the container along its length are consistent with the dimensions of the standard container along its width, the dimensions of the container along its width are consistent with the dimensions of the standard container along its height, the dimensions of one container along the height direction are smaller than the dimensions of the standard container along the height direction, and the sum of the dimensions of m1 containers in the m containers along the height direction is equal to the sum of the dimensions of n standard containers in the height direction.

[0009] In the above technical solution, the dimensions of the container along the length direction and the dimensions of the container along the width direction are consistent with those of the standard container, so that the horizontal area occupied by the container during transportation is consistent with that of the standard container, and the dimensions of m1 containers along the height direction are the dimensions of n standard containers along the height direction, so that the space occupied by m1 containers when stacked is the same as the space occupied by n standard containers, thereby improving the utilization rate of the space where the containers are placed, making full use of the available space along the height direction during transportation, reducing space waste during container transportation, reducing the transportation cost of containers and energy storage devices using containers, and thus reducing the use cost of the energy storage devices.

[0010] In some embodiments, m1 = 2, and n = 1. By setting the height of the two containers to the height of a standard container, when transporting multiple containers in the energy storage device, two adjacent containers can be stacked in the height direction, so that the two containers can just occupy the space required by a standard container, thereby improving the space utilization of the containers and helping to reduce the transportation cost of the containers.

[0011] In some embodiments, m1 = 3, and n = 1. By setting the height of the three containers to be the same as the height of a standard container, when transporting multiple containers in the energy storage device, three adjacent containers can be stacked in the height direction, so that the three containers can just occupy the space required by a standard container, thereby improving the space utilization of the containers and helping to reduce the transportation cost of the containers.

[0012] In some embodiments, m1 = 3, n = 2. By setting the height of the three containers to be the same as the height of two standard containers, when transporting multiple containers in the energy storage device, three adjacent containers can be stacked in the height direction, so that the three containers can just occupy the space required by two standard containers, thereby improving the space utilization of the containers and helping to reduce the transportation cost of the containers.

[0013] In some embodiments, at least a portion of the control compartment is arranged in a height direction with the container. By arranging at least a portion of the control compartment in a height direction with the container, the area occupied by the container in the horizontal direction can be reduced, thereby improving the space utilization of the energy storage device.

[0014] In some embodiments, the entire control compartment is located between two adjacent containers along the height direction. This helps connect the control module and thermal management module of the control compartment to the containers on both sides of the control compartment via shorter lines.

[0015] In some embodiments, the control compartment is entirely located at the bottom of the bottom container in the height direction. The control compartment being entirely located at the bottom of the bottom container makes the height of the control compartment relatively low, which is beneficial for maintenance of the control compartment.

[0016] In some embodiments, the control compartment is entirely located on top of the topmost container in the height direction. The control compartment is entirely located on top of the topmost container, and can cover the container, reducing sunlight exposure to the container, thereby reducing the risk of temperature imbalance in the container.

[0017] In some embodiments, along the height direction, the warehouse body includes a first top wall and multiple first side walls surrounding the first top wall, and the first top wall and at least one first side wall are provided with first ventilation holes, which are used for ventilation of the thermal management module.

[0018] In the above technical solution, the first vents are located at the first top and first side wall of the bin body, which helps the thermal management module to dissipate heat, so that the thermal management module can have a larger heat dissipation area and improve the temperature control effect of the thermal management module.

[0019] In some embodiments, the warehouse body includes an isolation layer, which separates the warehouse body into a first warehouse and a second warehouse. The first warehouse and the second warehouse share the isolation layer. The first warehouse includes the first top wall. The first warehouse is used to accommodate the thermal management module, and the second warehouse is used to accommodate the control module.

[0020] In the above technical solution, the isolation layer separates the thermal management module and the control module, reducing the risk of interference between the thermal management module and the control module.

[0021] In some embodiments, the control compartment includes a first connector electrically connected to the control module, and each container includes a second connector electrically connected to the battery cells, with the first connector being configured to mate with each second connector. The first connector mates with each second connector to enable quick connection between the control module and the battery cells, making connection between the control module and the battery cells more convenient.

[0022] In some embodiments, the size of the control bin along the length direction is consistent with the size of the standard container along the length direction, the size of the control bin along the width direction is consistent with the size of the standard container along the width direction, and p1 times the size of the control bin along the height direction is equal to the size of a standard container in the height direction, p1 is a positive integer, 2≤p1≤5.

[0023] By setting the p1 times of the height dimension of the control bin to be equal to the height dimension of a standard container, when the control bin is placed for transportation, the p1 times of the height of the control bin is equal to the height of a standard container. P1 control bins can be stacked and occupy the transportation space of a standard container, so as to facilitate the placement and transportation of the control bins and save the transportation cost of the control bins.

[0024] In some embodiments, the control compartment is hung on one side of at least one box body along the length direction or along the width direction. The above embodiment makes the installation or removal of the control compartment convenient.

[0025] In some embodiments, the warehouse body and the container body are separated. The above embodiment reduces the interference between the warehouse body and the container body, making the arrangement position of the control warehouse and the container more flexible.

[0026] In some embodiments, the housing includes an isolation layer that separates the housing into a first compartment and a second compartment. The first compartment and the second compartment share the isolation layer. The first compartment is used to accommodate the thermal management module, and the second compartment is used to accommodate the control module. By integrating the thermal management module and the control module into the housing, management of the thermal management module and the control module is facilitated.

[0027] In some embodiments, the container includes multiple batteries, each battery including a thermal management component and multiple battery cells. The control compartment also includes a third connector that communicates with the thermal management module. Each container also includes a fourth connector and a thermal management component that communicates with the fourth connector. The third connector is configured to mate with each of the fourth connectors.

[0028] In the above embodiment, the cooperation between the third connector and the fourth connector can achieve rapid connection between the thermal management component and the thermal management module, thereby facilitating the installation of the thermal management module.

[0029] In some embodiments, the container body includes a first compartment and a second compartment separate from the first compartment. The thermal management module is housed in the first compartment, which is located at the top of the topmost container. The control module includes a main control module, a power distribution module, a master control module, and a fire control module. The battery cells are electrically connected to the main control module, which is electrically connected to the master control module. The main control module, the master control module, and the fire control module are all electrically connected to the power distribution module. The main control module is located in the second compartment, and at least one of the power distribution module, the master control module, and the fire control module is located in the first compartment. By locating at least one of the power distribution module, the master control module, and the fire control module, and the thermal management module in the first compartment, the power distribution module, the master control module, the fire control module, and the thermal management module are transported separately from the container, reducing the difficulty and cost of container transportation. By locating the main control module in the second compartment, the control module configuration is more flexible and the risk of interference between the main control module and at least one of the power distribution module, the master control module, and the fire control module in the first compartment is reduced.

[0030] In some embodiments, the dimension of the first warehouse along the length direction is consistent with the dimension of the length direction of a standard container, the dimension of the first warehouse along the width direction is consistent with the dimension of the width direction of a standard container, and p2 times the dimension of the first warehouse along the height direction is equal to the dimension of the height direction of a standard container, p2 is a positive integer, 2≤p2≤5.

[0031] By setting the p2 times of the dimension of the first warehouse in the height direction equal to the dimension of the height direction of a standard container, when the first warehouse is placed for transportation, the p2 times of the height of the first warehouse is equal to the height of a standard container. P2 first warehouses can be stacked and occupy the transportation space of a standard container, so as to facilitate the placement and transportation of the first warehouse and save the transportation cost of the first warehouse.

[0032] In some embodiments, the housing includes a battery compartment that houses multiple battery cells, and a second compartment located within the housing and arranged lengthwise with the battery compartment. Providing the second compartment within the housing improves the stability of the connection between the main control module and the battery cells, facilitating electrical control of the battery cells by the control module.

[0033] In some embodiments, the second compartment is formed at an end of the box body along the length direction. By forming the second compartment at the end of the box body, the second compartment is easily installed and the interference of the second compartment with the battery cells is reduced during maintenance.

[0034] In some embodiments, the battery compartment has a first compartment door, and the second compartment has a first inspection door, and the first compartment door and the first inspection door are located on one side along the width direction. By providing the first inspection door on the container, it is convenient to inspect the main control module along the width direction, making the inspection of the main control module more convenient.

[0035] In some embodiments, the master control module is located within the first compartment. The first compartment includes a fifth connector electrically connected to the master control module. Each container includes a sixth connector and a master control module electrically connected to the sixth connector, with the fifth connector mating with each of the sixth connectors. The mating of the fifth and sixth connectors allows for quick connection between the master control module and the master control module, facilitating installation between the first compartment and the container.

[0036] In some embodiments, the housing includes a first compartment and a second compartment separate from the first compartment, with one of the thermal management module and the control module housed in the first compartment and the other housed in the second compartment. By housing the thermal management module and the control module in the first and second separate compartments, respectively, the risk of interference between the thermal management module and the control module is reduced, thereby improving the operational stability of the thermal management module and the control module.

[0037] In some embodiments, the first compartment is located at the top of the topmost container, and the second compartment is located at the bottom of the bottommost container. By housing the thermal management module and the control module in the first and second compartments, respectively, the risk of interference between the thermal management module and the control module is reduced, thereby improving the operational stability of the thermal management module and the control module.

[0038] In some embodiments, the first compartment is located on top of the topmost container, and the second compartment is located between two containers adjacent in height. By housing the thermal management module and the control module in the first and second compartments, respectively, the risk of interference between the thermal management module and the control module is reduced, thereby improving the operational stability of the thermal management module and the control module.

[0039] In some embodiments, the first compartment is located on top of the topmost container, and the second compartment is mounted on a side of at least one container along the length or width. By housing the thermal management module and the control module in the first and second compartments, respectively, the risk of interference between the thermal management module and the control module is reduced, thereby improving the operational stability of the thermal management module and the control module.

[0040] In some embodiments, the first compartment is located at the top of the topmost container, and the second compartment is separated from the container. By accommodating the thermal management module and the control module in the first and second compartments, respectively, the risk of interference between the thermal management module and the control module is reduced, and the operational stability of the thermal management module and the control module is improved.

[0041] In some embodiments, the first bin has a first locking member, and the top of the topmost container is provided with a second locking member. The first locking member and the second locking member cooperate to lock the first bin and the topmost container. Locking the first bin and the topmost container by the first and second locking members improves the positional stability of the first bin.

[0042] In some embodiments, the control module is housed in the second compartment. The second compartment is located at the bottom of the bottommost container; or the second compartment is located between two adjacent containers along the height direction. The length of the second compartment is consistent with the length of a standard container, the width of the second compartment is consistent with the width of a standard container, and p3 times the height of the second compartment is equal to the height of a standard container, where p3 is a positive integer and 2≤p3≤5.

[0043] By setting the p3 times of the size of the second warehouse in the height direction equal to the size of the height direction of a standard container, when the second warehouse is placed for transportation, the p3 times of the height of the control warehouse is equal to the height of a standard container. P3 second warehouses can be stacked and occupy the transportation space of a standard container, which facilitates the placement and transportation of the second warehouse and saves the transportation cost of the control warehouse.

[0044] In some embodiments, the control module is housed in the second compartment, which includes a seventh connector electrically connected to the control module. Each container includes an eighth connector electrically connected to a battery cell, with the seventh connector mating with each of the eighth connectors. The seventh and eighth connectors mating together enable quick connection between the control module and the battery cells, making installation of the second compartment and the container more convenient.

[0045] In some embodiments, the box body includes a battery compartment, the battery cells are accommodated in the battery compartment, the first compartment is located in the box body, and the first compartment is located at an end of the box body along the length direction.

[0046] By arranging the first compartment at the end of the box body along the length direction, the battery compartment and the control module are relatively independent, thereby reducing the risk of interference between the battery compartment and the control module.

[0047] In some embodiments, the second compartment is separated from the container; or the second compartment is located on the top of the topmost container; or the second compartment is mounted on one side of the container along the length or width. By separating the first and second compartments, the risk of interference between the thermal management module and the control module is reduced, thereby improving the operational stability of the thermal management module and the control module.

[0048] In some embodiments, the control module is housed within a first compartment, which has a second access door located at one side of the housing along its length. By positioning the second access door at an end of the housing along its length, the control module is positioned within the first compartment, thereby facilitating access to the control module at the end of the housing along its length.

[0049] In some embodiments, the first bin is mounted on a side of at least one container along the length or width, and the second bin is separated from the container. Separating the second bin from the container reduces the risk of interference between the second bin and the container, improving the operational stability of the second bin and the container.

[0050] In some embodiments, the container includes a battery compartment and a wiring harness compartment. Multiple battery cells are housed in the battery compartment, and the wiring harness compartment is located within the container and arranged lengthwise with the battery compartment. The wiring harness compartment has an opening, through which the wiring harness connecting the container and the control compartment at least partially passes. By providing the wiring harness compartment, the wiring harness connecting the container and the control compartment at least partially passes through the opening, reducing the risk of damage to the wiring harness connecting the container and the control compartment due to exposure to the outside of the container.

[0051] In some embodiments, the container includes multiple batteries arranged in rows and columns, with the batteries in each row arranged lengthwise and the batteries in each column arranged heightwise. Each battery includes a thermal management component and multiple battery cells. The container also includes a main circuit and multiple branch circuits. The main circuit connects the thermal management module and each branch circuit, and each branch circuit connects the thermal management components of the multiple batteries in a column.

[0052] The thermal management module is connected to the main line, and the thermal management module can provide fluid to the main line. The main line provides fluid to multiple branches respectively, making the temperature of the fluid entering the thermal management component more uniform and reducing the risk of battery temperature runaway.

[0053] In some embodiments, the container includes multiple batteries arranged in rows and columns, with the batteries in each row arranged lengthwise and the batteries in each column arranged heightwise. Each battery includes a thermal management component and multiple battery cells. The thermal management module includes a pumping device, a first heat exchanger, a compressor, a throttling device, and a second heat exchanger. The pumping device, the first heat exchanger, the thermal management component, and the pumping device are sequentially connected to form a cooling circuit. The compressor, the second heat exchanger, the throttling device, the first heat exchanger, and the compressor are sequentially connected to form a refrigerant circuit. The components of the thermal management module are independent of the batteries, reducing the risk of interference between the thermal management module and the batteries.

[0054] In some embodiments, the container includes battery cells disposed within the container, each weighing 5 kg to 60 kg. The weight of the battery cells is appropriate so that an appropriate number of batteries can be placed within the container, while maintaining a moderate energy density while meeting transportation requirements.

[0055] In some embodiments, the weight of the container is M, M≤35 tons. During the process of lifting the container, it is convenient to lift the relevant lifting devices and to transfer the container.

[0056] In some embodiments, the weight of the container is M, the total weight of the battery cells within the container is M1, and (M1 / M) × 100% ≥ 60%. This, on the one hand, can increase the weight ratio of the battery cells per unit volume of the container, thereby increasing the amount of energy stored per unit volume of the container. On the other hand, during container transportation, more battery cells that contribute to energy storage and are difficult to produce at the destination are transported, while other structures can be produced closer to the destination and do not require or reduce transportation. This helps reduce the transportation cost of the assembled energy storage device after the container is assembled into the energy storage device.

[0057] In some embodiments, (M1 / M)×100%≥80%. This further helps reduce the transportation cost of the assembled energy storage device.

[0058] In some embodiments, the weight of a container is M. A plurality of batteries are disposed within the container, including a container and battery cells. The battery cells are contained within the container. The total weight of the batteries is M2, and 70% ≤ (M2 / M) × 100% ≤ 90%. When (M2 / M) × 100% ≥ 70%, the weight ratio of the batteries per unit volume of the container can be increased, thereby increasing the energy density of the container. When (M2 / M) × 100% ≤ 90%, the structural strength of the container can be maintained. Therefore, when 70% ≤ (M2 / M) × 100% ≤ 90%, both the energy density and the structural strength of the container can be balanced, resulting in a more practical container.

[0059] In some embodiments, the volume of the container is V, the total volume of the battery cells within the container is V1, and (V1 / V)×100%≥30%. This can, on the one hand, increase the proportion of battery cell volume per unit volume of the container, thereby increasing the amount of electricity per unit volume of the container. On the other hand, during container transportation, more battery cells that contribute to energy storage and are difficult to produce and cannot be completed at the destination are transported. Other functional components of the energy storage device, such as control components, can be produced closer to the destination, eliminating the need for or reducing transportation costs. This helps reduce the transportation cost of the assembled energy storage device after the container is assembled into the energy storage device.

[0060] In some embodiments, (V1 / V)×100%≥50%, which is further beneficial to reducing the transportation cost of the assembled energy storage device.

[0061] In some embodiments, the volume of a container is V, and a plurality of batteries are disposed within the container. The batteries include a container and battery cells, which are contained within the container. The total volume of the batteries is V2, and 50% ≤ (V2 / V) × 100% ≤ 80%. When (V2 / V) × 100% ≥ 50%, the volume ratio of the batteries per unit volume of the container can be increased, thereby increasing the energy density of the container. When (V2 / V) × 100% ≤ 80%, the container can have sufficient volume for structural members to maintain the structural strength of the container. Therefore, when 50% ≤ (V2 / V) × 100% ≤ 80%, both the energy density and the structural strength of the container can be taken into account, making the container more practical.

[0062] In some embodiments, the energy of the container is E, the dimension of the container along the length direction is a, the dimension of the container along the width direction is b, 250KW / m 2 ≤E / (a×b)≤700KW / m 2 When E / (a×b)≥250KW / m 2 When E / (a×b)≤700KW / m 2 When the power is 250KW / m 2 ≤E / (a×b)≤700KW / m 2 At the same time, it takes into account the energy density and mass setting of the container, improves the practicality of the container, and facilitates the transportation of the container.

[0063] In some embodiments, 450KW / m 2 ≤E / (a×b)≤600KW / m 2 It can further improve the energy density and mass setting of the container, making it easier to transport the container.

[0064] In some embodiments, two adjacent containers in the height direction are welded, clamped, or connected via fasteners, which helps reduce the risk of the two adjacent containers moving relative to each other after being stacked, thereby improving the structural stability of the energy storage device.

[0065] In some embodiments, at least a portion of the control compartment is welded, clipped, or connected to adjacent containers along the height direction via fasteners, which helps reduce the risk of the control compartment and containers moving relative to each other after stacking, thereby improving the structural stability of the energy storage device.

[0066] In some embodiments, the plurality of containers includes a first container and a second container, wherein the first container is positioned above the second container. A limit pin is provided on the bottom of the first container, and a limit hole is provided on the top of the second container, with the limit pin engaging with the limit hole. The engagement of the limit pin and the limit hole secures the two adjacent containers, thereby limiting relative movement of the two adjacent containers using a simple structure.

[0067] In some embodiments, a first stopper is provided at the bottom of the first container, the first stopper being provided with a stopper slot, and a second stopper is provided at the top of the second container, the second stopper being provided with a stopper hole, with both ends of a stopper pin respectively engaging with the stopper slot and the stopper hole. By engaging the two ends of the stopper pin with the stopper slot and the stopper hole respectively, the two adjacent containers are secured, thereby limiting relative movement of the two adjacent containers using a simple structure.

[0068] In some embodiments, the energy storage device further includes a connecting mechanism configured to connect two adjacent containers in a height direction. The connecting mechanism includes a support member disposed between the two adjacent containers in the height direction. The sum of the height dimensions of m1 containers and the sum of the height dimensions of m1-1 support members among the m containers is equal to the sum of the height dimensions of n standard containers.

[0069] Connecting containers through a connecting mechanism makes stacking more stable. During container transportation, the sum of the height dimensions of m1 containers plus the sum of the height dimensions of the supports between two adjacent containers in the m1 container stack equals the sum of the heights of n standard containers. This allows for efficient use of the transport space occupied by the containers and reduces transportation costs.

[0070] In some embodiments, the connection mechanism further includes a locking member, wherein a support member is positioned between two adjacent containers in the height direction; the locking member is rotatably mounted on the support member about an axis extending in the height direction, and is used to lock two adjacent containers in the height direction. The support member positioned between the two adjacent containers in the height direction can achieve a connection between the two containers and also provide a buffer between the two containers. Locking the two containers together with the locking member further stabilizes the stacking of the containers.

[0071] In some embodiments, one of two containers adjacent in height has a first locking hole, and the other has a second locking hole, the first locking hole and the second locking hole being arranged opposite each other in the height direction; the locking accessory further comprises a first locking portion, a second locking portion, and a connecting portion, the connecting portion being rotatably arranged on a support member around an axis extending in the height direction, the connecting portion connecting the first locking portion and the second locking portion, the first locking portion and the second locking portion being located on opposite sides of the support member, and the connecting portion having a first position and a second position; when the connecting portion is in the first position, the first locking portion and the second locking portion can be inserted into or removed from the first locking hole and the second locking hole, respectively; when the connecting portion is in the second position, the first locking portion and the second locking portion can cooperate to lock the two adjacent containers. By switching the connecting portion between the first position and the second position, the locking accessory can lock or unlock the two adjacent containers, thereby facilitating assembly and disassembly of the two adjacent containers.

[0072] In some embodiments, the support member is provided with a through hole extending through the support member in a height direction, and the locking member is rotatably inserted into the through hole about an axis extending in the height direction. The connecting mechanism includes a driving arm connected to the locking member. The support member is disposed in a receiving cavity connected to the through hole, the receiving cavity extending through at least one end of the support member in a direction perpendicular to the height direction, and the driving arm is swingably disposed within the receiving cavity. The driving arm swings within the receiving cavity to switch the connecting portion between a first position and a second position, thereby facilitating rapid locking and unlocking of two adjacent containers.

[0073] In some embodiments, along the height direction, the heights of some of the m containers are different from the heights of other containers, thereby increasing the flexibility of container capacity and meeting different needs.

[0074] In some embodiments, the m containers have the same dimensions along the height direction, thereby simplifying the manufacturing process and reducing costs.

[0075] In some embodiments, the standard container is a 20-foot standard container, and the height of the standard container is 2896 mm, 2591 mm, or 2438 mm. The sum of the dimensions of the m1 containers 10 along the height direction Z is the height of the 20-foot standard container, 2896 mm, 2591 mm, or 2438 mm.

[0076] In a second aspect, an embodiment of the present application provides a container comprising a box body and battery cells, wherein the battery cells are housed in the box body, wherein the dimensions of the container along the length direction and the dimensions along the width direction are respectively consistent with those of a standard container, and the dimension of the container along the height direction is smaller than the dimension of a standard container along the height direction.

[0077] In the above embodiment, by setting the height dimension of the container to be smaller than the height dimension of a standard container in the height direction, the height of the container during transportation does not exceed the height of the corresponding standard container for sea or land transportation in the height direction of the container, which is beneficial to improving the convenience of container transportation and reducing the transportation cost of the container and the energy storage device using the container.

[0078] In some embodiments, the height of the container is twice or three times the height of a standard container. This can reduce the use of structural components and increase the weight of battery cells per unit volume. Furthermore, it can fully utilize the available height space during transportation, reduce space waste during container transportation, and thus reduce transportation costs.

[0079] In some embodiments, the top of the container has multiple lifting parts that are configured to cooperate with a sling to lift the container. The sling and the lifting parts cooperate to lift the container, thereby facilitating stacking of the containers in a vertical direction or facilitating lifting operations during transportation.

[0080] In some embodiments, the lifting portion includes a load-bearing portion, a receiving slot, and an opening. The receiving slot is located inside the load-bearing portion, and the opening connects the receiving slot with the outside of the receiving slot. The opening is located at the top of the load-bearing portion. The lifting portion has a simple structure and is convenient for lifting the container.

[0081] In some embodiments, the bottom of the container body has a limit pin, which is used to cooperate with the container body of an adjacent container to limit the position. A simple structure is used to achieve the purpose of limiting the relative movement of two adjacent containers.

[0082] In some embodiments, the box contains a plurality of batteries arranged in rows and columns, and each battery includes a plurality of battery cells.

[0083] In a third aspect, an embodiment of the present application provides an energy storage device, comprising a plurality of containers provided by any one embodiment of the second aspect, wherein the plurality of containers are stacked in a height direction.

[0084] In some embodiments, the energy storage device further includes a connecting mechanism configured to connect two containers adjacent in height, the connecting mechanism including a support member disposed between the two adjacent containers in the height direction. The sum of the height dimensions of m1 containers and the sum of the height dimensions of m1-1 support members in the plurality of containers equals the sum of the height dimensions of n standard containers. When transporting containers, stacking the m1 containers with support members disposed between adjacent containers ensures that the stacked height of the m1 containers equals the height of n standard containers. This ensures that the space required to transport the m1 containers is the same as the space required to transport the n standard containers, thereby efficiently utilizing the container space and saving transportation costs.

[0085] In a fourth aspect, an embodiment of the present application provides an energy storage device, comprising a control bin and a container provided by any one embodiment of the second aspect. The control bin comprises a bin body, a control module, and a thermal management module, the control module being used to electrically control the battery cells, and the thermal management module being used to manage the temperature of the battery cells. The bin body and the container are arranged along the height direction of the container, the thermal management module and / or at least part of the control module is disposed within the bin body, the size of the bin body along its length direction is consistent with the size of the standard container in the length direction, the size of the bin body along its width direction is consistent with the size of the standard container in the width direction, and p times the size of the bin body in the height direction is equal to the size of the standard container in the height direction, p is a positive integer, and 2≤p≤5.

[0086] By providing a control module, the control module can control the input or output of electrical energy to the battery cells, achieving electrical control of the battery cells. By providing a thermal management module, the thermal management module can manage the temperature of the battery cells, reducing the risk of temperature runaway. The warehouse body can integrate the control module and thermal management module, facilitating maintenance of the control and thermal management modules. The height dimension of the warehouse body is smaller than the height dimension of a standard container. During transportation, the warehouse body does not exceed the height of a corresponding standard container for sea or land transport, which improves the convenience of warehouse body transportation. The length and width dimensions of the warehouse body are consistent with those of a standard container, so that the horizontal area occupied by the warehouse body during transportation is consistent with that of a standard container. The height dimension of the warehouse body is p times the height dimension of a standard container. When p warehouse bodies are stacked, the space occupied by p warehouse bodies is the same as that of a standard container. This improves the space utilization of the warehouse body, facilitates the full utilization of the available height space during transportation, reduces space waste during warehouse transportation, reduces the transportation cost of the warehouse body and the energy storage device using the warehouse body, and thus reduces the cost of using the energy storage device.

[0087] In some embodiments, some control modules are disposed in the warehouse body, and the remaining control modules are disposed in the container.

[0088] In some embodiments, the control module includes a main control module, a power distribution module, a general control module and a fire control module, and the main control module, the general control module and the fire control module are all electrically connected to the power distribution module.

[0089] In some embodiments, at least one of the main control module, power distribution module, thermal management module, master control module, and busbar is not located within the container. In this embodiment, at least one of the main control module, power distribution module, thermal management module, master control module, and busbar is not located within the container. This design, on the one hand, allows the space previously occupied by at least one of the main control module, power distribution module, thermal management module, master control module, and busbar within the container to be used for batteries, thereby increasing the number of batteries within the container, maximizing the utilization of the container's internal space, and thereby improving the energy density of the entire energy storage container. Furthermore, the reduced number of components within the container can reduce the frequency of operation and maintenance during normal use of the energy storage container.

[0090] The main control module provides battery control. The power distribution module provides power and circuit protection for electrical devices. The thermal management module drives the flow of coolant. The master control module monitors and manages the batteries. The busbar connects multiple cable branches within the energy storage container.

[0091] In a fifth aspect, an embodiment of the present application provides an energy storage system, comprising a power conversion device, and the energy storage device provided in any embodiment of the first aspect or any embodiment of the fourth aspect, wherein the power conversion device is used to electrically connect a power generation device and an energy storage device.

[0092] In some embodiments, the energy storage system further includes a transformer, which is electrically connected to the power conversion device and is used to electrically connect to the power grid; at least two containers are arranged along the length direction; the warehouse body and the box body are separated, and the control warehouse, the power conversion device, and the transformer are arranged along the length direction, and the total span of the control warehouse, the power conversion device, and the transformer along the length direction is less than or equal to the total span of the two adjacent containers along the length direction. By making the sum of the length dimensions of the control warehouse, the power conversion device, and the transformer less than or equal to the sum of the length dimensions of two standard containers, the control warehouse, the transformer, and the power conversion device can only occupy the size of two standard containers when transported together, thereby reducing transportation costs.

[0093] In some embodiments, the energy storage system further includes a transformer, which is electrically connected to the power conversion device and is used to electrically connect to the power grid; at least two containers are arranged along the length direction; the control compartment includes a first compartment and a second compartment, the first compartment is connected to the box body, and the second compartment is separated from the box body; the second compartment, the power conversion device, and the transformer are arranged along the length direction, and the total span of the second compartment, the power conversion device, and the transformer along the length direction is less than or equal to the total span of the two adjacent containers along the length direction. By making the sum of the length dimensions of the second compartment, the length dimensions of the power conversion device, and the length dimensions of the transformer less than or equal to the sum of the length dimensions of two standard containers, the second compartment, the transformer, and the power conversion device can only occupy the size of two standard containers when transported together, thereby reducing transportation costs.

DETAILED DESCRIPTION

[0132] The following detailed description of the embodiments of the present application is provided in conjunction with the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of the present application, but are not intended to limit the scope of the present application, i.e., the present application is not limited to the described embodiments.

[0133] In the description of this application, it should be noted that, unless otherwise specified, "multiple" means more than two; the terms "upper", "lower", "left", "right", "inside", "outside", etc., indicating directions or positional relationships, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. "Vertical" is not strictly perpendicular, but is within the allowable error range. "Parallel" is not strictly parallel, but is within the allowable error range.

[0134] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0135] It should also be noted that, in the description of this application, unless otherwise specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0136] The term "plurality" used in this application refers to two or more (including two).

[0137] In this application, battery cells may include lithium-ion secondary battery cells, lithium-ion primary battery cells, lithium-sulfur battery cells, sodium-lithium-ion battery cells, sodium-ion battery cells, or magnesium-ion battery cells, and the embodiments of this application are not limited thereto. Battery cells may be cylindrical, flat, rectangular, or in other shapes, and the embodiments of this application are not limited thereto.

[0138] The battery mentioned in the embodiments of the present application may include one or more battery cells to provide a single physical module with higher voltage and capacity. When there are multiple battery cells, the multiple battery cells are connected in series, in parallel or in hybrid through a busbar.

[0139] In some embodiments, the battery may be a battery module; when there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module.

[0140] In some embodiments, the battery may be a battery pack, which includes a receiving box and battery cells, wherein the battery cells or battery modules are received in the receiving box.

[0141] In some embodiments, the energy storage device includes an energy storage container, an energy storage cabinet, etc.

[0142] A battery cell typically includes an electrode assembly. This assembly includes a positive electrode, a negative electrode, and a separator. During the charge and discharge process of a battery cell, active ions (such as lithium ions) are inserted and removed between the positive and negative electrodes. The separator, located between the positive and negative electrodes, prevents short circuits while allowing the active ions to pass through.

[0143] Optionally, the electrode assembly is a wound structure, wherein the positive electrode sheet and the negative electrode sheet are wound into a wound structure.

[0144] Optionally, the electrode assembly is a laminated structure.

[0145] Optionally, the shape of the electrode assembly can be cylindrical, flat, or polygonal.

[0146] Power plants are increasingly demanding higher area energy density for energy storage containers. Consequently, to increase the amount of electricity they can hold, the weight of the containers is also increasing. However, containers must be transported from production sites to their intended destinations by land and / or sea, and these transport methods often have weight restrictions. This creates a conflict between the increased energy density and the weight of the energy storage containers.

[0147] In view of this, an embodiment of the present application proposes a new technical solution. The technical solution described in the embodiment of the present application is applicable to containers and energy storage devices including containers.

[0148] Energy storage devices can be used in energy storage power stations, wind power generation systems, solar power generation systems, mobile power systems or temporary power supply systems, etc. Energy storage power stations can store electrical energy during low electricity consumption periods, and provide electrical energy to relevant users or electrical equipment during peak electricity consumption periods. The wind energy collected by the wind turbines of the wind power generation system is converted into electrical energy, which is then stored by the energy storage device. The solar power generation system can convert solar energy into electrical energy, which is then stored by the energy storage device and supplied to users in due course. Mobile power systems can supply power to relevant electrical equipment in places where the power grid cannot reach, such as remote mountainous areas, remote wilderness areas, and other areas. Temporary power supply systems can supply power to users when there is insufficient power supply. The energy storage system provided in the embodiment of the present application can be any power system that requires an energy storage device.

[0149] Please refer to Figure 1, which is a schematic diagram of the structure of a charging network 1000 provided in some embodiments of the present application. Embodiments of the present application provide a charging network 1000, which includes charging piles 200, which are used to charge electrical devices. Charging network 1000 may also include an energy storage device 100, which is electrically connected to charging piles 200 and is used to provide electrical energy to charging piles 200.

[0150] It should be noted that the charging pile 200 is electrically connected to the battery cells 21 in the energy storage device 100 via a cable. The battery cells 21 can provide their stored energy to the charging pile 200. The charging pile 200 has a connector that can be connected to an electrical device to replenish energy. The application of the energy storage device 100 in the charging network 1000 can effectively improve the safety of the charging network 1000 and also help increase the flexibility of the charging network 1000 during deployment.

[0151] In a charging network 1000 , there may be one charging pile 200 , and the energy storage device 100 provides power to the one charging pile 200 ; there may also be multiple charging piles 200 , and the energy storage device 100 provides power to multiple charging piles 200 .

[0152] The energy storage device 100 may include a container 10 . The container 10 includes a box body 1 and a battery cell 21 . The battery cell 21 is electrically connected to the charging pile 200 so that the battery cell 21 provides electrical energy to the charging pile 200 .

[0153] As an example, as shown in FIG1 , a charging network 1000 includes one energy storage device 100 and two charging piles 200 , and one energy storage device 100 provides electrical energy to the two charging piles 200 .

[0154] Please refer to Figure 2, which is a schematic diagram of the structure of an energy storage system 2000 provided in some embodiments of the present application. An embodiment of the present application provides an energy storage system 2000. The energy storage system 2000 includes a power conversion device 300, which can be electrically connected to a power generation device 3000 to convert the electric power provided by the power generation device 3000. The energy storage system 2000 may also include an energy storage device 100, which is electrically connected to the power conversion device 300. The power conversion device 300 converts the electric energy provided by the power generation device 3000 into the energy storage device 100 for storage.

[0155] The power conversion device is used to connect between the power generation device 3000 and the energy storage device 100. The power generation device 3000 is used to generate electrical energy, and the power generation device 3000 is used to store the generated electrical energy in the energy storage device 100 through the power conversion device. The energy storage system 2000 uses the energy storage device 100 to effectively improve the operational safety of the energy storage system 2000. In a specific implementation, the power generation equipment can specifically include solar panels, hydropower generation equipment, thermal power generation equipment, etc. The specific type of power generation equipment is not limited in this application.

[0156] As an example, as shown in FIG2 , the energy storage system 2000 includes an energy storage device 100 and a power conversion device 300 . The two power generation devices 3000 transmit the generated electric energy to the power conversion device 300 , respectively, and the electric energy is introduced into the energy storage device 100 for storage through the power conversion device 300 .

[0157] Please refer to Figure 3, which is a structural diagram of the energy storage device 100 provided in some embodiments of the present application. An embodiment of the present application provides an energy storage device 100, which includes a container 10 and a control compartment 20. There are m containers 10, m ≥ 2, and the m containers 10 are arranged along the height direction Z of the container 10. The container 10 includes a box body 1 and battery cells 21 (shown in Figure 22). There are multiple battery cells 21, and multiple battery cells 21 are accommodated in the box body 1. The control compartment 20 includes a compartment body 201, a control module 202 and a thermal management module 203. The control module 202 and the thermal management module 203 are accommodated in the compartment body 201. The control module 202 and the thermal management module 203 are both connected to the container 10. The control module 202 is used to electrically control the battery cells 21, and the thermal management module 203 is used to manage the temperature of the battery cells 21. Among them, the size of the container 10 along its length direction X is consistent with the size of the standard container in the length direction X, the size of the container 10 along its width direction Y is consistent with the size of the standard container in the width direction Y, the size of a container 10 along the height direction Z is smaller than the size of the standard container in the height direction Z, and the sum of the sizes of m1 containers 10 in the height direction Z among the m containers 10 is equal to the sum of the sizes of n standard containers in the height direction Z.

[0158] The standard container may be the size of a standard container during transportation, such as 20 feet, 30 feet, 40 feet or 45 feet, which meets the corresponding standards, and its length, width and height have corresponding dimensions respectively.

[0159] 20 feet can include: the dimension in the length direction X is 6058mm, with a tolerance of 0mm-6mm; the dimension in the width direction Y is 2438mm, with a tolerance of 0mm-5mm; and the dimension in the height direction Z is 2896mm, 2591mm or not more than 2438mm; the tolerance is 0mm-5mm.

[0160] 30 feet can include: the dimension in the length direction X is 9125mm, with a tolerance of 0mm-10mm; the dimension in the second direction is 2438mm, with a tolerance of 0mm-5mm; and the dimension in the height direction Z is 2896mm, 2591mm or not more than 2438mm; with a tolerance of 0mm-5mm.

[0161] 40 feet can include: the dimension in the length direction X is 12192mm, with a tolerance of 0mm-10mm; the dimension in the width direction Y is 2438mm, with a tolerance of 0mm-5mm; and the dimension in the height direction Z is 2896mm, 2591mm or not more than 2438mm; the tolerance is 0mm-5mm.

[0162] 45 feet can include: the dimension in the length direction X is 13716mm, with a tolerance of 0mm-10mm; the dimension in the width direction Y is 2438mm, with a tolerance of 0mm-5mm; and the dimension in the height direction Z is 2591mm or 2896mm; with a tolerance of 0mm-5mm.

[0163] Alternatively, for containers of various sizes, dimensions within a range of ±5% of the dimensions thereof may be regarded as dimensions within the tolerance range.

[0164] The dimensions of the containers 10 along the height direction Z can be uniform, and can be one-m1 of the dimensions of n standard containers. That is, the dimensions of m1 containers 10 along the height direction Z are equal to the dimensions of n standard containers along the height direction Z. Thus, when n is 1, m1 containers 10 can be assembled into the dimensions of a single standard container, making it convenient to assemble them into the dimensions of a single standard container for land and sea transport. When n is an integer greater than 1, m1 containers 10 can be assembled into the dimensions of n standard containers, also making it convenient to transport them in the dimensions of a standard container. When assembled into the dimensions of a standard container for transportation, transportation costs can be significantly reduced.

[0165] Alternatively, the m containers 10 may have different sizes along the height direction Z, but the sum of the sizes of at least m1 of the containers 10 along the height direction Z must be equal to the sizes of n standard containers along the height direction Z. In this way, the m1 containers of different sizes can be assembled into one or more standard container sizes, greatly facilitating transportation and reducing transportation costs.

[0166] In the embodiment of the present application, the sum of the dimensions of the m1 containers 10 along the height direction Z is equal to the sum of the dimensions of the n standard containers along the height direction Z. This means that the sum of the dimensions of the m1 containers 10 along the height direction Z is approximately equal to the sum of the dimensions of the n standard containers along the height direction Z. When the difference between the sum of the dimensions of the m1 containers 10 along the height direction Z and the sum of the dimensions of the n standard containers along the height direction Z is within the aforementioned tolerance range, the dimensions can be considered to be approximately equal.

[0167] Optionally, the approximately equal difference is W, where W ≤ m1 × 35 mm - 30 mm. For example, if m1 = 2, the approximately equal difference W can be a maximum of 40 mm. When the difference between the sum of the heights of the two containers 10 and the size of a standard container is within 40 mm, the sum of the dimensions of the two containers 10 in the height direction Z is equal to the dimension of the height of the standard container in the height direction Z. For another example, if m1 = 3, the approximately equal difference W can be a maximum of 75 mm. When the difference between the sum of the heights of the three containers 10 and the size of a standard container is within 75 mm, the sum of the dimensions of the three containers 10 in the height direction Z is equal to the dimension of the height of the standard container in the height direction Z. Alternatively, when the difference between the sum of the heights of the three containers 10 and the size of two standard containers is within 75 mm, the sum of the dimensions of the three containers 10 in the height direction Z is equal to the sum of the dimensions of the two standard containers in the height direction Z.

[0168] Alternatively, due to manufacturing errors, the sum of the dimensions of the m1 containers 10 may be subject to m1 manufacturing errors W1, where W1 ≤ 5 mm, and the sum of the dimensions of the m1 containers 10 along the height direction Z may be equal to the sum of the dimensions of n standard containers along the height direction Z. Alternatively, the sum of the dimensions of the m1 containers 10 along the height direction Z plus m1 W1 may be equal to the sum of the dimensions of n standard containers along the height direction Z. As an example, m1 = 2, n = 1, the height h of each container 10 is 1293 mm, and the corresponding height H of a standard container is 2591 mm. n × H - m1 × h = 5 mm, and 5 mm < m1 × W1 = 10 mm; therefore, the sum of the dimensions of the m1 containers 10 along the height direction Z is equal to the sum of the dimensions of the n standard containers along the height direction Z.

[0169] Alternatively, if the containers 10 assembled for transport are connected and secured along the height direction Z by supports 1011, then the dimensions of the m1 containers 10 constituting n standard containers also include the height dimensions of the supports 1011 between them. In other words, when the supports 1011 are installed, the height dimensions of some of the m1 containers can be the sum of their own height and the height of the supports 1011 connected to them. This is because the supports 1011 connecting the containers 10 along the height direction Z also contribute to a certain degree of the height dimensions of the containers 10.

[0170] For example, when m1 containers 10 are assembled and secured for transportation using supports 1011, the sum of the dimensions of the m1 containers 10 along the height direction Z and the sum of the dimensions of the m1-1 supports 1011 along the height direction Z equals the sum of the dimensions of n standard containers along the height direction Z. Alternatively, the number of supports between the m1 containers 10 may be less than m1-1. In this case, when these containers 10 are assembled to the standard container size, the sum of the dimensions of the m1 containers and the sum of the actual support member sizes is included.

[0171] For example, the dimension of the support member 1011 is W2, where W2 ≤ 30 mm. For example, if m1 = 3 and n = 2, and the height h of each container 10 is 845 mm, the corresponding height H of a standard container is 2591 mm. Therefore, n × H - m1 × h = 56 mm, and 56 mm < m1 × W1 + (m1 - 1) × W2 = 75 mm. Therefore, the sum of the dimensions of m1 containers 10 along the height direction Z is equal to the sum of the dimensions of n standard containers along the height direction Z. Here, W = m1 × W1 + (m1 - 1) × W2.

[0172] Therefore, when the energy storage device 100 of the embodiment of the present application uses supports 1011 during transportation, but supports 1011 are not required between the containers 10 that make up the energy storage device 100, "the sum of the dimensions of the m1 containers along the height direction is equal to the sum of the dimensions of the n standard containers along the height direction" should be understood to include the height of the used supports 1011. In other words, the sum of the dimensions of the m1 containers along the height direction is equal to the sum of the dimensions of the n standard containers along the height direction minus the sum of the heights of the used supports 1011. This situation also falls within the scope of the embodiment of claim 1 of the present application.

[0173] The container 10 is generally a rectangular parallelepiped structure, with the length direction X and width direction Y of the container 10 both parallel to the horizontal plane, and the length direction X of the container 10 is parallel to the longest side of the rectangular parallelepiped structure of the container 10. The height direction Z of the container 10 is perpendicular to the ground.

[0174] The dimension a of the container 10 along the length direction X is the distance between the two ends of the container 10 along the length direction X; the dimension b of the container 10 along the width direction Y is the distance between the two ends of the container 10 along the width direction Y; and the dimension h of the container 10 along the height direction Z is the distance between the two ends of the container 10 along the height direction Z. The above dimensions a, b, and h represent the maximum dimensions of the outer contour of the container 10 in the corresponding directions. The container body 1 of the container 10 may include eight corner fittings 15 (shown in Figure 13) and six walls 16 (shown in Figure 13). The eight corner fittings 15 are located at the eight corners of the container's rectangular parallelepiped structure and protrude from the walls 16 of the container body 1. The total span of the two corner fittings 15 arranged along the height direction is the height of the container, the total span of the two corner fittings 15 arranged along the length direction is the length of the container, and the total span of the two corner fittings 15 arranged along the width direction is the width of the container. When calculating the dimensions of the container 10, pipes and cables connected to the container and located outside the container are not counted as part of the dimensions of the container 10.

[0175] The number of containers 10 in the energy storage device 100 can be any number, two or more. For example, the energy storage device 100 may include two containers 10, which are stacked in the height direction Z. Another example is that the energy storage device 100 may include three containers 10, which are stacked in the height direction Z. It is understood that if the number of containers 10 in the energy storage device 100 is too large, damage to the bottommost container 1 may occur. The sum of the heights of all the containers 10 stacked in the height direction Z is less than or equal to the sum of the heights of eight standard containers stacked together.

[0176] The m1 containers 10 among the m containers 10 refer to any m1 containers 10 among the m containers 10. For example, the energy storage device 100 has three containers 10, namely a first container, a second container, and a third container. If m1=2, the two containers can be the first container and the third container, the first container and the second container, or the second container and the third container.

[0177] m1 can be less than m, and the sum of the dimensions of some of the m containers 10 along the height direction Z is equal to the sum of the dimensions of n standard containers along the height direction Z. For example, m = 8, m1 = 5, and n = 3; the five containers 10 can be any five of the eight containers 10.

[0178] Alternatively, m1=m, where the sum of the dimensions of m containers 10 in the height direction Z is equal to the sum of the dimensions of n standard containers in the height direction Z. For example, m=2, where the sum of the heights of two containers 10 is equal to the height of one standard container.

[0179] It can be understood that m, m1, and n are all positive integers.

[0180] The control compartment 20's housing 201 can be a separate compartment, housing both the control module 202 and the thermal management module 203. The control compartment 20 and the container 10 can be detachably connected, for example, by snap-fitting or bolting; they can also be fixedly connected, for example, by welding; or the housing 201 and the container 1 can be separated.

[0181] The warehouse body 201 may also be a collection of multiple independent warehouses. For example, the warehouse body 201 includes multiple warehouse sections, the thermal management module 203 is disposed in one of the warehouse sections, and the control module 202 is disposed in another of the warehouse sections.

[0182] The control module 202 may include a main control module 2021, a power distribution module 2023, a master control module 2022, and a fire control module 2024. The main control module 2021, power distribution module 2023, master control module 2022, and fire control module 2024 may be located in the same compartment or separately in different compartments. The main control module 2021 is used to control the input and output of high-voltage electrical energy to and from the battery cells 21 within the container 10. The master control module 2022 is used to control the switching operation of the main control module 2021 within the container 10. The fire control module 2024 is used to control the operation of firefighting components in the event of a temperature imbalance and fire in the container 10. The firefighting components may be fire extinguishers, etc., and may be located in the control compartment 20 or within the container 10. The power distribution module 2023 is used to electrically connect the main control module 2021, the general control module 2022 and the fire control module 2024, so as to facilitate the circuit conduction of the main control module 2021, the general control module 2022 and the fire control module 2024 and maintain the normal operation of the main control module 2021, the general control module 2022 and the fire control module 2024.

[0183] A main control module 2021 may correspond one-to-one with a container 10, with one main control module 2021 controlling the input and output of electrical energy from a single battery cell 21 within a container 10. Alternatively, multiple battery cells 21 within a container 10 may form multiple batteries 2, with a main control module 2021 corresponding one-to-one with a single battery 2, with one main control module 2021 controlling the input or output of electrical energy from a single battery 2. Alternatively, one main control module 2021 may control the input or output of electrical energy from multiple battery cells 21 within multiple containers 10. A container 10 may contain multiple battery groups 2, with multiple batteries 2 connected in series to form a battery cluster 2, and multiple battery clusters 2 connected in parallel. A single main control module 2021 may control one or more battery clusters 2. Accordingly, when a container 10 has multiple main control modules 2021, the main control modules 2021 may be located within a single main control box or multiple main control boxes.

[0184] The battery cells 21 are placed in the box 1. Multiple battery cells 21 can be connected in series, parallel or mixed and then placed directly in the box 1; or multiple battery cells 21 can be connected in series, parallel or mixed and then placed in the receiving box 23 to form a battery 2 and then placed in the box 1.

[0185] In the above technical solution, by providing a control module 202, the control module 202 can control the input or output of electrical energy of the battery cell 21, thereby realizing electrical control of the battery cell 21. By providing a thermal management module 203, the thermal management module 203 can manage the temperature of the battery cell 21, thereby reducing the risk of temperature runaway of the battery cell 21. The warehouse body 201 can integrate the control module 202 and the thermal management module 203, which is beneficial for the maintenance of the control module 202 and the thermal management module 203. By setting the dimension of the container 10 in the height direction Z to be smaller than the dimension of a standard box in the height direction Z, the height of the container 10 in the height direction Z of the container 10 during transportation does not exceed the height of the corresponding standard container for sea or land transportation in the height direction Z of the container 10, which is beneficial for improving the convenience of the container 10 during transportation. The dimensions of the container 10 along the length direction X and the width direction Y are consistent with those of a standard container, so that the horizontal area occupied by the container 10 during transportation is consistent with that of a standard container. The dimensions of m1 containers 10 along the height direction Z are equal to the dimensions of n standard containers along the height direction Z. This allows the space occupied by m1 containers 10 when stacked to be the same as that occupied by n standard containers. This improves the utilization rate of the space in which the containers 10 are placed, facilitates full utilization of the available space along the height direction Z during transportation, reduces space waste during transportation of the containers 10, reduces the transportation costs of the containers 10 and the energy storage device 100 using the containers 10, and thus reduces the cost of using the energy storage device 100. The stacking of the containers 10 can also reduce floor space and save space.

[0186] In some embodiments, m1=2, n=1.

[0187] The energy storage device 100 may include more than two containers 10 , for example, the energy storage device 100 may include 3, 5, or 8 containers 10 . Alternatively, the energy storage device 100 may include only two containers 10 .

[0188] By setting the height of the two containers 10 to be the height of a standard container, when transporting multiple containers 10 in the energy storage device 100, two adjacent containers 10 can be stacked along the height direction Z, so that the two containers 10 can just occupy the space required by a standard container, thereby improving the space utilization rate of the containers 10 and helping to reduce the transportation cost of the containers 10.

[0189] In some embodiments, m1=3, n=1. By setting the height of the three containers 10 to be the height of a standard container, when transporting multiple containers 10 in the energy storage device 100, three adjacent containers 10 can be stacked in the height direction Z, so that the three containers 10 can occupy exactly the space required by a standard container, thereby improving the space utilization of the containers 10 and helping to reduce the transportation cost of the containers 10.

[0190] In some embodiments, m1=3, n=2. By setting the height of the three containers 10 to be the height of two standard containers, when transporting multiple containers 10 in the energy storage device 100, three adjacent containers 10 can be stacked in the height direction Z, so that the three containers 10 can just occupy the space required by two standard containers, thereby improving the space utilization of the containers 10 and helping to reduce the transportation cost of the containers 10.

[0191] In some embodiments, at least a portion of the control compartment 20 is arranged along the height direction Z with the container 10 .

[0192] The control compartment 20 may be arranged as a whole with the container 10 along the height direction Z. The control compartment 20 may be an independent compartment or a collection of multiple compartments. Alternatively, the control compartment 20 may include multiple compartment sections, with a portion of the multiple compartment sections arranged along the height direction Z with the container 10.

[0193] By arranging at least a portion of the control compartment 20 and the container 10 along the height direction Z, the area occupied by the container 10 in the horizontal direction can be reduced, thereby improving the space utilization of the energy storage device 100.

[0194] In some embodiments, along the height direction Z, the control compartment 20 is entirely located between two adjacent containers 10 .

[0195] The control module 202 and thermal management module 203 are both located between two adjacent containers 10. The entire control compartment 20 is located between two adjacent containers 10, which facilitates connecting the control module 202 and thermal management module 203 of the control compartment 20 to the containers 10 on both sides of the control compartment 20 via shorter wires. The location of the control compartment 20 between two adjacent containers 10 also facilitates maintenance.

[0196] In some embodiments, the control compartment 20 is entirely located at the bottom of the bottommost container 10 along the height direction Z. The control module 202 and the thermal management module 203 are both located between two adjacent containers 10. The entire location of the control compartment 20 at the bottom of the bottommost container 10 reduces the height of the control compartment 20, facilitating maintenance of the control compartment 20.

[0197] In some embodiments, along the height direction Z, the control compartment 20 is entirely located on the top of the topmost container 10 .

[0198] The control compartment 20 and the m containers 10 are stacked along the height direction Z, and the only container 10 adjacent to the control compartment 20 is located on the top of the m containers 10 along the height direction Z.

[0199] In the above embodiment, the control compartment 20 is entirely located on the top of the topmost container 10 . The control compartment 20 can cover the container 10 , reducing sunlight exposure to the container 10 , thereby reducing the risk of temperature imbalance in the container 10 .

[0200] Please refer to Figures 3 and 4. Figure 4 is a schematic diagram of the structure of the energy storage device 100 provided in some embodiments of the present application (illustrating the first vent 201a). In some embodiments, along the height direction Z, the storage body 201 includes a first top wall 2011 and a plurality of first side walls 2012 surrounding the first top wall 2011. The first top wall 2011 and at least one of the first side walls 2012 are provided with a first vent 201a. The first vent 201a is used to ventilate the thermal management module 203.

[0201] The first top wall 2011 may be entirely opened 33 to form a first vent 201a. Alternatively, the first top wall 2011 may be partially opened 33 to form a first vent 201a. For example, the first top wall 2011 may be provided with an opening 33 on one side along the longitudinal direction X, so that the portion of the first top wall 2011 forms the first vent 201a.

[0202] All the first side walls 2012 may be provided with the first ventilation openings 201 a , or only a portion of the first side walls 2012 may be provided with the first ventilation openings 201 a .

[0203] In the above technical solution, the first ventilation opening 201a is located at the first top and the first side wall 2012 of the storage body 201, which helps the thermal management module 203 to dissipate heat, so that the thermal management module 203 can have more heat dissipation channels and improve the temperature control effect of the thermal management module 203.

[0204] 3 . In some embodiments, the housing 201 includes an isolation layer 2015 , which separates the housing 201 into a first compartment 2013 and a second compartment 2014 . The first compartment 2013 and the second compartment 2014 share the isolation layer 2015 . The first compartment 2013 includes a first top wall 2011 . The first compartment 2013 is used to accommodate the thermal management module 203 , and the second compartment 2014 is used to accommodate the control module 202 .

[0205] The first bin 2013 and the second bin 2014 are stacked in a height direction Z, with the first bin 2013 located above the second bin 2014. The first top wall 2011 is located on the top of the first bin 2013. The first bin 2013 and the second bin 2014 may share a first side wall 2012, and the first side wall 2012 located at the first bin 2013 is provided with a first vent 201a.

[0206] The first compartment 2013 is located at the top of the compartment body 201, allowing the thermal management module 203 to be located at the top of the compartment body 201. There is no obstruction above the thermal management module 203, which facilitates heat dissipation from the thermal management module 203. The first compartment 2013 is separated from the second compartment 2014 by an isolation layer 2015. The isolation layer 2015 separates the thermal management module 203 from the control module 202, reducing interference from the thermal management module 203 on the control module 202 and also reducing the impact of external rainfall or sunlight on the control module 202.

[0207] In the above technical solution, the isolation layer 2015 separates the thermal management module 203 and the control module 202 , thereby reducing the risk of interference between the thermal management module 203 and the control module 202 .

[0208] Please refer to Figure 5, which is a schematic diagram of the structure of the energy storage device 100 provided in some embodiments of the present application (showing the first connector 10b). In some embodiments, the control compartment 20 includes a first connector 10b, which is electrically connected to the control module 202. Each container 10 includes a second connector 10c, which is electrically connected to the battery cell 21. The first connector 10b is configured to mate with each second connector 10c.

[0209] The first connector 10b can be directly connected to the second connector 10c to achieve the matching of the first connector 10b and the second connector 10c. For example, the first connector 10b can be plugged into and matched with each second connector 10c. The first connector 10b can be fixed to the housing 201, and the second connector 10c can be movably arranged on the case 1; the first connector 10b can be movably arranged on the housing 201, and the second connector 10c can be fixed on the case 1; or the first connector 10b and the second connector 10c can be movably arranged on the housing 201 and the case 1 respectively. The first connector 10b can include multiple connecting parts, and the connecting parts correspond to and are connected to the second connectors 10c one by one to achieve the connection between the first connector 10b and multiple second connectors 10c.

[0210] Alternatively, the first connector 10b and the second connector 10c may be connected via a connector, which may be a cable. Alternatively, the first connector 10b and the second connector 10c may be fixed to the housing 201 and the case 1, respectively; alternatively, the first connector 10b may be fixed to the housing 201, and the second connector 10c may be movably disposed on the case 1; alternatively, the first connector 10b may be movably disposed on the housing 201, and the second connector 10c may be fixed to the case 1; alternatively, the first connector 10b and the second connector 10c may be movably disposed on the housing 201 and the case 1, respectively.

[0211] As an example, as shown in FIG5 , a first connector 10b is fixedly mounted on the control compartment 20, and two second connectors 10c are respectively fixed to the two boxes 1. The first connector 10b and the second connector 10c are connected by a cable. The cable can be a quick-connect cable with quick-connect connectors at both ends, and the two quick-connect connectors are respectively connected to the first connector 10b and the second connector 10c.

[0212] In the embodiment in which the first connector 10b and the second connector 10c are connected by a cable, the cable may be at least partially passed through the interior of the container 10 and the control compartment 20, or part of the cable may be passed out to the outside of the control compartment 20 and the container 10; the interface of the first connector 10b may be located outside the control compartment 20, and all the cables may be located outside the control compartment 20; or the interface of the second connector 10c may be located outside the box 1, and all the cables may be located outside the box 1.

[0213] By cooperating with the first connector 10 b and each second connector 10 c , the control module 202 and the battery cell 21 can be quickly connected, making the connection between the control module 202 and the battery cell 21 more convenient.

[0214] In some embodiments, the size of the control bin 20 along the length direction X is consistent with the size of the standard container in the length direction X, the size of the control bin 20 along the width direction Y is consistent with the size of the standard container in the width direction Y, and p1 times the size of the control bin 20 along the height direction Z is equal to the size of the height direction Z of a standard container, p1 is a positive integer, 2≤p1≤5.

[0215] p1 times the size of the control bin 20 along the height direction Z is equal to the size of a standard container in the height direction Z, which means that p1 times the size of the control bin 20 along the height direction Z is approximately equal to the size of a standard container in the height direction Z. When the difference between p1 times the size of the control bin 20 and the size of a standard container in the height direction Z is within a range, the sizes can be considered to be approximately equal. The approximately equal difference is W, W≤p1×35mm-30mm. For example, p1=3, the approximately equal difference W can be up to 75mm. When the difference between the sum of the heights of the three control bins 20 and the size of a standard container is less than or equal to 75mm, the sum of the sizes of the three control bins 20 along the height direction Z is equal to the size of a standard container in the height direction Z.

[0216] The size of the control compartment 20 along the height direction Z can be 1 / 2, 1 / 3, 1 / 4, or 1 / 5 of the size of a standard container along the height direction Z. For example, when the size of the control compartment 20 along the height direction Z is 1 / 3 of the size of a standard container along the height direction Z, triple the size of the control compartment 20 along the height direction Z to equal the size of a standard container along the height direction Z.

[0217] By setting p1 times the size of the control bin 20 along the height direction Z to be equal to the size of the height direction Z of a standard container, when the control bin 20 is placed for transportation, p1 times the height of p1 control bins 20 is equal to the height of a standard container, and the p1 control bins 20 can be stacked to facilitate the placement and transportation of the control bin 20, saving the transportation cost of the control bin 20.

[0218] In some embodiments, when multiple control bins 20 are stacked for assembly or for land or sea transportation, a support member 1011 may also be provided between two adjacent control bins 20 along the height direction Z. P1 control bins 20 may be stacked so that the sum of the dimensions of the p1 control bins 20 along the height direction Z is the same as the dimension of a standard container; or p1 control bins 20 may be stacked and a support member 1011 may be provided between every two adjacent control bins 20, and the sum of the dimensions of the p1-1 support members 1011 along the height direction Z and the sum of the dimensions of the p1 control bins 20 along the height direction Z is the same as the dimension of a standard container.

[0219] A support member 1011 may be provided between every two control compartments 20 ; a support member 1011 may be provided only between some adjacent control compartments 20 ; or no support member may be provided between all adjacent control compartments 20 .

[0220] In some embodiments, the size of the control bin 20 along the length direction X is consistent with the size of the standard container along the length direction X, the size of the control bin 20 along the width direction Y is consistent with the size of the standard container along the width direction Y, and p1 times the size of the control bin 20 along the height direction Z is equal to the size of n standard containers in the height direction Z, p1 is a positive integer, 2≤p1≤5, n is greater than or equal to 2, n is less than p1, and n is a positive integer.

[0221] As an example, three times the size of the control compartment 20 in the height direction Z is equal to the size of two standard containers in the height direction Z.

[0222] In the embodiment where the control compartment 20 and the container 10 are stacked along the height direction Z, a support member 1011 may be provided between the control compartment 20 and the container 10 , or may not be provided.

[0223] Please refer to Figure 6, which is a schematic diagram of the structure of the energy storage device 100 provided in some embodiments of the present application (showing that the control compartment 20 is hung on the box body 1). In some embodiments, the control compartment 20 is hung on one side of at least one box body 1 along the length direction X or along the width direction Y.

[0224] The control compartment 20 may be hung on one side of a box body 1 along the length direction X, or on one side of a box body 1 along the width direction Y. Alternatively, one control compartment 20 may be hung on the same side of multiple boxes 1 along the length direction X, or on the same side of multiple boxes 1 along the width direction Y.

[0225] The control compartment 20 being mounted on at least one housing 1 means that the control compartment 20 is located outside the housing 1 and is connected to at least one housing 1. The control compartment 20 may be mounted on the outside of one housing 1 or on the outside of two housings 1. The control compartment 20 and the housing 1 may be fixed by bolts, hinges, welding, or a frame.

[0226] As an example, as shown in FIG6 , the control compartment 20 is hung on one side of the two boxes 1 along the length direction X.

[0227] By hanging the control compartment 20 on one side of at least one box body 1 along the length direction X or along the width direction Y, the control compartment 20 can be easily installed or removed.

[0228] In some embodiments, the chamber 201 is separated from the housing 1. The chamber 201 of the control chamber 20 and the container 10 do not contact each other. The thermal management module 203 and control module 202 within the control chamber 20 can be connected to the container 10 via pipes and cables. This reduces interference between the chamber 201 and the housing 1, allowing for greater flexibility in the configuration of the control chamber 20 and the container 10.

[0229] In some embodiments, the housing 201 includes an isolation layer 2015, which separates the housing 201 into a first compartment 2013 and a second compartment 2014. The first compartment 2013 and the second compartment 2014 share the isolation layer 2015. The first compartment 2013 is used to accommodate the thermal management module 203, and the second compartment 2014 is used to accommodate the control module 202. The housing 201 acts as an independent physical module, and the thermal management module 203 and the control module 202 are both located within the physical module, and the thermal management module 203 and the control module 202 are separated by the isolation layer 2015. By integrating the thermal management module 203 and the control module 202 into the housing 201, the management of the thermal management module 203 and the control module 202 is facilitated.

[0230] 5 , in some embodiments, the container 10 includes multiple batteries 2, each of which includes a thermal management component 22 and multiple battery cells 21. The control compartment 20 also includes a third connector 10d, which is in communication with the thermal management module 203. Each container 10 also includes a fourth connector 10e and a thermal management component 22 in communication with the fourth connector 10e. The third connector 10d is configured to mate with each of the fourth connectors 10e.

[0231] The third connector 10d can be directly connected to the fourth connector 10e to achieve the matching of the third connector 10d and the fourth connector 10e. For example, the third connector 10d can be plugged into and matched with each of the fourth connectors 10e. The third connector 10d can be fixed to the housing 201, and the fourth connector 10e can be movably mounted on the case 1. Alternatively, the third connector 10d can be movably mounted on the housing 201, and the fourth connector 10e can be fixed to the case 1. Alternatively, the third connector 10d and the fourth connector 10e can be movably mounted on the housing 201 and the case 1, respectively. The third connector 10d can include multiple connecting portions, each corresponding to and connected to the fourth connector 10e, to achieve the connection between the third connector 10d and the multiple fourth connectors 10e.

[0232] Alternatively, the third connector 10d and the fourth connector 10e may be connected via a connector, which may be a pipe. The third connector 10d and the fourth connector 10e may be fixed to the silo 201 and the housing 1, respectively; the third connector 10d may be fixed to the silo 201, and the fourth connector 10e may be movably mounted on the housing 1; the third connector 10d may be movably mounted on the silo 201, and the fourth connector 10e may be fixed to the housing 1; or the third connector 10d and the fourth connector 10e may be movably mounted on the silo 201 and the housing 1, respectively.

[0233] As an example, as shown in FIG5 , the thermal management module 203 is equipped with a third connector 10d, and each container 10 is equipped with a fourth connector 10e. The third connector 10d and the fourth connector 10e are connected by a pipeline. The pipeline can be a quick-connect pipeline with quick-connect fittings at both ends. The first connector 10b and the second connector 10c are also quick-connect fittings. The two quick-connect fittings at both ends of the pipeline are connected to the first connector 10b and the second connector 10c, respectively.

[0234] In the above embodiment, the third connector 10 d and the fourth connector 10 e cooperate to achieve rapid connection between the thermal management component 22 and the thermal management module 203 , thereby facilitating installation of the thermal management module 203 .

[0235] Please refer to Figure 7, which is a schematic diagram of the structure of the energy storage device 100 provided in some embodiments of the present application (showing that the main control module 2021 is located in the second compartment 2014). In some embodiments, the container body 201 includes a first compartment 2013 and a second compartment 2014 that is separate from the first compartment 2013. The thermal management module 203 is housed in the first compartment 2013, which is located at the top of the topmost container 10. The control module 202 includes a main control module 2021, a power distribution module 2023, a general control module 2022 and a fire control module 2024. The battery cell 21 is electrically connected to the main control module 2021, and the main control module 2021 is electrically connected to the general control module 2022. The main control module 2021, the general control module 2022 and the fire control module 2024 are all electrically connected to the power distribution module 2023. The main control module 2021 is located in the second compartment 2014, and at least one of the power distribution module 2023, the general control module 2022 and the fire control module 2024 is located in the first compartment 2013.

[0236] The power distribution module 2023, the main control module 2022 and the fire control module 2024 may all be located in the first warehouse 2013; or only one of the power distribution module 2023, the main control module 2022 and the fire control module 2024 may be located in the first warehouse 2013; or any two of the power distribution module 2023, the main control module 2022 and the fire control module 2024 may be located in the first warehouse 2013.

[0237] There may be a one-to-one correspondence between the main control modules 2021 and the containers 10. There may be multiple main control modules 2021 located in one second compartment 2014, or one main control module 2021 may be located in one second compartment 2014.

[0238] The second compartment 2014 may be separated from the housing 1, located within the container 10, or directly connected to the container 10. Separating the second compartment 2014 from the housing 1 means that the second compartment 2014 and the container 10 are not in contact with each other, and the control module 202 in the second compartment 2014 and the container 10 can be connected via a cable.

[0239] As an example, as shown in Figure 7, the master control module 2022, the power distribution module 2023, and the fire control module 2024 are all provided in a master control box 2025, which is provided in the first compartment 2013. Each cabinet 1 is provided with a second compartment 2014, in which the control module 202 is provided.

[0240] By locating at least one of the power distribution module 2023, the master control module 2022, and the fire control module 2024, and the thermal management module 203 in the first compartment 2013, the power distribution module 2023, the master control module 2022, and the fire control module 2024, and the thermal management module 203 can be transported separately from the container 10, thereby reducing the difficulty and cost of transporting the container 10. By locating the main control module 2021 in the second compartment 2014, the placement of the control module 202 is more flexible, reducing the risk of interference between the main control module 2021 and at least one of the power distribution module 2023, the master control module 2022, and the fire control module 2024 in the first compartment 2013.

[0241] In some embodiments, the dimension of the first warehouse 2013 along the length direction X is consistent with the dimension of the length direction X of a standard container, the dimension of the first warehouse 2013 along the width direction Y is consistent with the dimension of the width direction Y of a standard container, and p2 times the dimension of the first warehouse 2013 along the height direction Z is equal to the dimension of the height direction Z of a standard container, p2 is a positive integer, 2≤p2≤5.

[0242] The dimension p2 times the height Z dimension of the first compartment 2013 is equal to the dimension of the height Z dimension of a standard container. This means that the dimension p2 times the height Z dimension of the first compartment 2013 is approximately equal to the dimension of the height Z dimension of a standard container. When the difference between the dimension p2 times the height Z dimension of the first compartment 2013 and the dimension of the height Z dimension of a standard container is within a certain range, the dimensions are considered to be approximately equal. The approximately equal difference is W, where W ≤ p2 × 35mm - 30mm. For example, if p2 = 3, the approximately equal difference W can be up to 75mm. When the difference between the sum of the heights of the three first compartments 2013 and the dimension of a standard container is within 75mm, the sum of the heights of the three first compartments 2013 is equal to the dimension of the height Z dimension of a standard container.

[0243] The size of the first compartment 2013 along the height direction Z can be 1 / 2, 1 / 3, 1 / 4, or 1 / 5 of the size of a standard container along the height direction Z. For example, when the size of the first compartment 2013 along the height direction Z is 1 / 3 of the size of a standard container along the height direction Z, three times the size of the first compartment 2013 along the height direction Z is equal to the size of a standard container along the height direction Z.

[0244] By setting p2 times the size of the first warehouse 2013 along the height direction Z to be equal to the size of the height direction Z of a standard container, when the first warehouse 2013 is placed for transportation, p2 times the height of the first warehouse 2013 is equal to the height of a standard container, and p2 first warehouses 2013 can be stacked to facilitate the placement and transportation of the first warehouse 2013, saving the transportation cost of the first warehouse 2013.

[0245] In some embodiments, when p2 first warehouses 2013 are stacked for assembly or for land or sea transportation, a support member 1011 may also be provided between two adjacent first warehouses 2013 along the height direction Z. The p2 first warehouses 2013 may be stacked so that the sum of the dimensions of the p2 first warehouses 2013 along the height direction Z is the same as the dimension of a standard container; or the p2 first warehouses 2013 may be stacked and a support member 1011 is provided between every two adjacent first warehouses 2013, and the sum of the dimensions of the p2-1 support member 1011 along the height direction Z and the sum of the dimensions of the p2 first warehouses 2013 along the height direction Z is the same as the dimension of a standard container.

[0246] A support member 1011 may be provided between every two first bins 2013 ; a support member 1011 may be provided only between some adjacent first bins 2013 ; or no support member may be provided between all adjacent first bins 2013 .

[0247] In the embodiment where the first warehouse 2013 and the container 10 are stacked along the height direction Z, a support member 1011 may be provided between the first warehouse 2013 and the container 10, or may not be provided.

[0248] In some embodiments, the housing 1 includes a battery compartment 11 , in which the battery cells 21 are housed. The second compartment 2014 is located in the housing 1 and is arranged along the length direction X with the battery compartment 11 .

[0249] The second compartment 2014 may be located between two adjacent battery compartments 11 along the length direction X; or the second compartment 2014 may be located on one side of all battery compartments 11 along the length direction X.

[0250] The second compartment 2014 can be separated from the battery compartment 11 by a partition, facilitating temperature control of the battery cells 21 in the battery compartment 11. Adjacent columns of batteries 2 can be separated by a partition, or they can be separated without a partition. Placing the second compartment 2014 within the housing 1 improves the stability of the connection between the main control module 2021 and the battery cells 21, facilitating electrical control of the battery cells 21 by the control module 202. Placing the second compartment 2014 within the housing 1 also facilitates maintenance of the main control module 2021 and shortens the connection between the battery cells 2 and the main control module 2021, reducing the internal resistance of the energy storage device 100.

[0251] Please refer to Figure 8, which is a schematic diagram of the structure of the energy storage device 100 provided in some embodiments of the present application (showing the first access door 2016). In some embodiments, along the length direction X, the second compartment 2014 is formed at the end of the box body 1.

[0252] The second compartment 2014 is located in the box body 1 and at one end of the box body 1 along the length direction X.

[0253] By forming the second compartment 2014 at the end of the box body 1, the installation of the second compartment 2014 is facilitated, and the interference of the second compartment 2014 on the battery cells 21 is reduced during maintenance.

[0254] 7-9 , FIG9 illustrates an arrangement of the energy storage device 100 according to some embodiments of the present application. In some embodiments, the battery compartment 11 has a first compartment door 111 , and the second compartment 2014 has a first access door 2016 . The first compartment door 111 and the first access door 2016 are located on one side along the width direction Y.

[0255] One of the walls disposed on either side of the container 10 along the width direction Y houses the first compartment door 111 and the first inspection door 2016. The first compartment door 111 allows batteries 2 to be added to or removed from the container 10 when the first compartment door 111 is open. When the first compartment door 111 is closed, the first compartment door 111 isolates the batteries 2 from the outside world, reducing the risk of external interference with the batteries 2. The first inspection door 2016 is located on the same side of the first compartment door 111. Opening the first inspection door 2016 facilitates inspection of the main control module 2021 located within the second compartment 2014.

[0256] As an example, the energy storage device 100 in Figure 8 can be arranged according to the arrangement structure of the energy storage device 100 in Figure 9, so that the first inspection door 2016 and the first compartment door 111 of each energy storage device 100 are located on both sides of the arrangement structure along the width direction Y, thereby facilitating the inspection of the main control module 2021.

[0257] In FIG. 9 , the distance between adjacent energy storage devices 100 may be less than 300 mm to reduce the footprint of the multiple energy storage devices 100 .

[0258] By providing the first inspection door 2016 on the container 10 , it is advantageous to inspect the main control module 2021 along the width direction Y, making the inspection of the main control module 2021 more convenient.

[0259] In some embodiments, referring to FIG. 7 , the master control module 2022 is located within the first compartment 2013. The first compartment 2013 includes a fifth connector 10f electrically connected to the master control module 2022. Each container 10 includes a sixth connector 10i and a master control module 2021 electrically connected to the sixth connector 10i. The fifth connector 10f is configured to mate with each sixth connector 10i.

[0260] The fifth connector 10f can be directly connected to the sixth connector 10i to achieve the matching of the fifth connector 10f and the sixth connector 10i. For example, the fifth connector 10f can be plugged into and matched with each of the sixth connectors 10i. The fifth connector 10f can be fixed to the first compartment 2013, and the sixth connector 10i can be movably mounted on the housing 1. Alternatively, the fifth connector 10f can be movably mounted on the first compartment 2013, and the sixth connector 10i can be fixed on the housing 1. Alternatively, the fifth connector 10f and the sixth connector 10i can be movably mounted on the first compartment 2013 and the housing 1, respectively. The fifth connector 10f can include multiple connecting portions, each corresponding to and connected to the sixth connector 10i, to achieve the connection between the fifth connector 10f and multiple sixth connectors 10i.

[0261] Alternatively, the fifth connector 10f and the sixth connector 10i may be connected via a connector, which may be a cable. Alternatively, the fifth connector 10f and the sixth connector 10i may be fixed to the first compartment 2013 and the housing 1, respectively. Alternatively, the fifth connector 10f may be fixed to the first compartment 2013, and the sixth connector 10i may be movably mounted on the housing 1. Alternatively, the fifth connector 10f may be movably mounted on the first compartment 2013, and the sixth connector 10i may be fixed to the housing 1. Alternatively, the fifth connector 10f and the sixth connector 10i may be movably mounted on the first compartment 2013 and the housing 1, respectively.

[0262] As shown in Figure 7, a fifth connector 10f is installed in the first compartment 2013 and is electrically connected to the master control module 2022 in the master control box 2025. A sixth connector 10i is installed in the second compartment 2014 and is electrically connected to the master control module 2021. The sixth connector 10i and the fifth connector 10f are connected by a cable.

[0263] The connection cables of the fifth connector 10 f and the sixth connector 10 i are passed through the second compartment 2014 located inside the container 10 .

[0264] By cooperating with the fifth connector 10f and the sixth connector 10i, the general control module 2022 and the main control module 2021 can be quickly connected, which facilitates the installation between the first warehouse 2013 and the container 10.

[0265] Please refer to Figures 10 to 13. Figure 10 is a schematic diagram of the structure of the energy storage module provided in some embodiments of the present application (showing that the second compartment 2014 is located at the bottom of the bottommost container 10); Figure 11 is a schematic diagram of the structure of the energy storage module provided in some embodiments of the present application (showing that the second compartment 2014 is located between two adjacent containers 10); Figure 12 is a schematic diagram of the structure of the energy storage module provided in some embodiments of the present application (showing that the second compartment 2014 is hung on a container 10); Figure 13 is a schematic diagram of the structure of the energy storage module provided in some embodiments of the present application (showing that the second compartment 2014 is separated from the box body 1). In some embodiments, the container body 201 includes a first compartment 2013 and a second compartment 2014 that is separate from the first compartment 2013. One of the thermal management module 203 and the control module 202 is accommodated in the first compartment 2013, and the other is accommodated in the second compartment 2014.

[0266] The thermal management module 203 may be accommodated in the first compartment 2013 and the control module 202 may be accommodated in the second compartment 2014 ; or the thermal management module 203 may be accommodated in the second compartment 2014 and the control module 202 may be accommodated in the first compartment 2013 .

[0267] By accommodating the thermal management module 203 and the control module 202 in the first compartment 2013 and the second compartment 2014 respectively, the risk of interference between the thermal management module 203 and the control module 202 is reduced, and the stability of use of the thermal management module 203 and the control module 202 is improved.

[0268] 10 , in some embodiments, the first compartment 2013 is located at the top of the topmost container 10 , and the second compartment 2014 is located at the bottom of the bottommost container 10 .

[0269] The thermal management module 203 may be located at the top of the topmost container 10 and the control module 202 may be located at the bottom of the bottommost container 10; or the control module 202 may be located at the top of the topmost container 10 and the thermal management module 203 may be located at the bottom of the bottommost container 10.

[0270] By accommodating the thermal management module 203 and the control module 202 in the first compartment 2013 and the second compartment 2014 respectively, the risk of interference between the thermal management module 203 and the control module 202 is reduced, and the stability of use of the thermal management module 203 and the control module 202 is improved; on the other hand, it is conducive to the flexible placement of the thermal management module 203 and the control module 202, which is conducive to the rational use of the space of the container 10 and the improvement of energy density.

[0271] Referring to FIG. 11 , in some embodiments, the first warehouse 2013 is located on the top of the topmost container 10 , and the second warehouse 2014 is located between two adjacent containers 10 along the height direction Z.

[0272] The thermal management module 203 may be located at the top of the topmost container 10, and the control module 202 may be located between two adjacent containers 10 along the height direction Z; or the control module 202 may be located at the top of the topmost container 10, and the thermal management module 203 may be located between two adjacent containers 10 along the height direction Z.

[0273] By accommodating the thermal management module 203 and the control module 202 in the first warehouse 2013 and the second warehouse 2014 respectively, the risk of interference between the thermal management module 203 and the control module 202 is reduced, and the stability of use of the thermal management module 203 and the control module 202 is improved. The second warehouse 2014 is located between two adjacent containers 10 along the height direction Z, which is conducive to the maintenance of the devices in the second warehouse 2014 and is conducive to the connection of the second warehouse 2014 with its two adjacent containers 10.

[0274] 12 , in some embodiments, the first compartment 2013 is located on the top of the topmost container 10 , and the second compartment 2014 is hung on one side of at least one container 10 along the length direction X or along the width direction Y.

[0275] The thermal management module 203 may be located at the top of the topmost container 10, and the second compartment 2014 where the control module 202 is located may be hung on one side of at least one container 10 along the length direction X or along the width direction Y; or the control module 202 may be located at the top of the topmost container 10, and the second compartment 2014 where the thermal management module 203 is located may be hung on one side of at least one container 10 along the length direction X or along the width direction Y.

[0276] The second warehouse 2014 may be mounted on one side of a container 10 along the length direction X, or on one side of a container 10 along the width direction Y. Alternatively, one second warehouse 2014 may be mounted on one side of multiple containers 10 along the length direction X, or on one side of multiple containers 10 along the width direction Y.

[0277] As an example, as shown in FIG12 , the second warehouse 2014 is hung on one side of the two containers 10 along the length direction X.

[0278] The second compartment 2014 and the container 10 can be fixed by bolts, hinges, welding or by a frame.

[0279] By accommodating the thermal management module 203 and the control module 202 in the first and second compartments 2013 and 2014, respectively, which are separately arranged, the risk of interference between the thermal management module 203 and the control module 202 is reduced, and the stability of use of the thermal management module 203 and the control module 202 is improved; by hanging the second compartment 2014 on one side of at least one container 10 along the length direction X or along the width direction Y, it is facilitated to install and disassemble the second compartment 2014, and the second compartment 2014 being located on one side of the container 10 along the length direction X or along the width direction Y is also conducive to the maintenance of the devices in the second compartment 2014.

[0280] Referring to FIG. 13 , in some embodiments, the first compartment 2013 is located on the top of the topmost container 10 , and the second compartment 2014 is separated from the container body 1 .

[0281] When the second compartment 2014 contains the thermal management module 203, the second compartment 2014 can be connected to the container 10 through a pipeline, and the second compartment 2014 is separated from the box body 1; when the second compartment 2014 contains the control module 202, the second compartment 2014 can be connected to the container 10 through a cable, and the second compartment 2014 is separated from the box body 1.

[0282] The thermal management module 203 may be located at the top of the topmost container 10, and the second compartment 2014 where the control module 202 is located may be separated from the box body 1; or the control module 202 may be located at the top of the topmost container 10, and the second compartment 2014 where the thermal management module 203 is located may be separated from the box body 1.

[0283] As an example, as shown in FIG13 , the thermal management component 22 is located in the first compartment 2013, which is located at the top of the topmost container 10. The main control module 2021, power distribution module 2023, master control module 2022, and fire control module 2024 are all located in the second compartment 2014, which is separated from the container body 1. Each container 10 is provided with a quick-connect interface 2026. The control module 202 in the second compartment 2014 is electrically connected to the container 10 via a cable that mates with the quick-connect interface 2026. The quick-connect interface 2026 can be located on one side of the container 10 along the longitudinal direction X.

[0284] By accommodating the thermal management module 203 and the control module 202 in the separately arranged first compartment 2013 and second compartment 2014 respectively, the risk of interference between the thermal management module 203 and the control module 202 is reduced, and the operational stability of the thermal management module 203 and the control module 202 is improved; the second compartment 2014 is placed separately from the box body 1, which can reduce the risk of interference between the second compartment 2014 and the container 10, making the setting position of the second compartment 2014 more flexible.

[0285] In some embodiments, the quick-connect interface 2026 may be the second connector 10c, the fourth connector 10e, the sixth connector 10i, or the eighth connector 10k.

[0286] In some embodiments, a recess 20261 is provided on one side of the container 1 along the length direction X or along one side along the width direction Y, and the quick-connect interface 2026 is disposed within the recess 20261. The quick-connect interface 2026 disposed within the recess 20261 can reduce the volume of the container 10 occupied by the quick-connect interface 2026 and enhance the waterproofing of the quick-connect interface 2026, reducing the effects of rain and dust on the quick-connect interface 2026.

[0287] Please refer to Figure 14, which is a partial enlarged view of area A in Figure 13. In some embodiments, the first compartment 2013 has a first locking member 20131, and the top of the topmost container 10 is provided with a second locking member 20132. The first locking member 20131 and the second locking member 20132 are used to cooperate and lock the first compartment 2013 and the topmost container 10.

[0288] As an example, as shown in FIG14 , first locking member 20131 and second locking member 20132 are both lock seats, and are bolted together to secure first compartment 2013 and topmost container 10. First compartment 2013 may be a thermal management module 203. The cables connecting thermal management module 203 and container 10 may be partially routed through one side of container 10 along its length direction X, exposing them to the exterior of container 10 and minimizing space occupied within container 10. Alternatively, they may be entirely located within thermal management module 203 and container 10 to protect the cables.

[0289] The first lock member 20131 and the second lock member 20132 lock the first compartment 2013 and the container 10 at the top, thereby improving the position stability of the first compartment 2013.

[0290] Continuing with Figures 10 and 11 , in some embodiments, the dimension of the second compartment 2014 along the length direction X is consistent with the dimension of a standard container along the length direction X, the dimension of the second compartment 2014 along the width direction Y is consistent with the dimension of a standard container along the width direction Y, and p3 times the dimension of the second compartment 2014 along the height direction Z is equal to the dimension of a standard container along the height direction Z, where p3 is a positive integer and 2≤p3≤5.

[0291] The dimension p3 times the height Z dimension of the second compartment 2014 is equal to the dimension of the height Z dimension of a standard container. This means that the dimension p3 times the height Z dimension of the second compartment 2014 is approximately equal to the dimension of the height Z dimension of a standard container. When the difference between the dimension p3 times the height Z dimension of the second compartment 2014 and the dimension of the height Z dimension of a standard container is within a certain range, the dimensions are considered to be approximately equal. The approximately equal difference is W, where W ≤ p3 × 35mm - 30mm. For example, if p3 = 3, the approximately equal difference W can be up to 75mm. When the difference between the sum of the heights of the three second compartments 2014 and the dimension of a standard container is within 75mm, the sum of the heights of the three second compartments 2014 is equal to the dimension of the height Z dimension of a standard container.

[0292] The size of the second compartment 2014 along the height direction Z can be 1 / 2, 1 / 3, 1 / 4, or 1 / 5 of the size of a standard container along the height direction Z. For example, when the size of the second compartment 2014 along the height direction Z is 1 / 3 of the size of a standard container along the height direction Z, three times the size of the second compartment 2014 along the height direction Z is equal to the size of a standard container along the height direction Z.

[0293] By setting p3 times the size of the second warehouse 2014 along the height direction Z to be equal to the size of the height direction Z of a standard container, when the second warehouse 2014 is placed for transportation, p3 times the height of the control warehouse 20 is equal to a standard container, and p3 second warehouses 2014 can be stacked to facilitate the placement and transportation of the second warehouse 2014, saving the transportation cost of the control warehouse 20.

[0294] In some embodiments, when p3 second warehouses 2014 are stacked for assembly or for land or sea transportation, a support member 1011 may also be provided between two adjacent second warehouses 2014 along the height direction Z. The p3 second warehouses 2014 may be stacked so that the sum of the dimensions of the p3 second warehouses 2014 along the height direction Z is the same as the dimension of a standard container; or the p3 second warehouses 2014 may be stacked and a support member 1011 is provided between every two adjacent second warehouses 2014, and the sum of the dimensions of the p3-1 support member 1011 along the height direction Z and the sum of the dimensions of the p3 second warehouses 2014 along the height direction Z is the same as the dimension of a standard container.

[0295] A support member 1011 may be provided between every two second bins 2014 ; a support member 1011 may be provided only between some adjacent second bins 2014 ; or no support member may be provided between all adjacent second bins 2014 .

[0296] In the embodiment where the second warehouse 2014 and the container 10 are stacked along the height direction Z, a support member 1011 may be provided between the second warehouse 2014 and the container 10, or may not be provided.

[0297] In some embodiments, the control module 202 is housed in the second compartment 2014, the second compartment 2014 includes a seventh connector 10j, the seventh connector 10j is electrically connected to the control module 202, each container 10 includes an eighth connector 10k, the eighth connector 10k is electrically connected to the battery cell 21, and the seventh connector 10j is used to cooperate with each eighth connector 10k.

[0298] The seventh connector 10j can be directly connected to the eighth connector 10k to achieve the mating of the seventh connector 10j and the eighth connector 10k. For example, the seventh connector 10j can be plugged into and mated with each of the eighth connectors 10k. The seventh connector 10j can be fixed to the second compartment 2014, and the eighth connector 10k can be movably disposed in the housing 1. Alternatively, the seventh connector 10j can be movably disposed in the second compartment 2014, and the eighth connector 10k can be fixed in the housing 1. Alternatively, the seventh connector 10j and the eighth connector 10k can be movably disposed in the second compartment 2014 and the housing 1, respectively. The seventh connector 10j can include multiple connecting portions, each corresponding to and connected to the eighth connector 10k, to achieve the connection between the seventh connector 10j and multiple eighth connectors 10k.

[0299] Alternatively, the seventh connector 10j and the eighth connector 10k may be connected via a connector, which may be a cable. Alternatively, the seventh connector 10j and the eighth connector 10k may be fixed to the second compartment 2014 and the housing 1, respectively; alternatively, the seventh connector 10j may be fixed to the second compartment 2014, and the eighth connector 10k may be movably disposed in the housing 1; alternatively, the seventh connector 10j may be movably disposed in the second compartment 2014, and the eighth connector 10k may be fixed in the housing 1; alternatively, the seventh connector 10j and the eighth connector 10k may be movably disposed in the second compartment 2014 and the housing 1, respectively.

[0300] As an example, as shown in FIG10 , a seventh connector 10 j is installed in the second compartment 2014 , an eighth connector 10 k is installed in each box 1 , and the seventh connector 10 j and the eighth connector 10 k are connected by a cable.

[0301] By cooperating with the seventh connector 10j and the eighth connector 10k, the control module 202 and the battery cell 21 can be quickly connected, making the installation of the second compartment 2014 and the container 10 more convenient.

[0302] In some embodiments, please refer to Figure 15, which is a schematic diagram of the structure of an energy storage device 100 (first compartment 2013 located within housing 1) provided in further embodiments of the present application. Housing 1 includes a battery compartment 11, in which battery cells 21 are accommodated. First compartment 2013 is located within housing 1, and first compartment 2013 is located at an end of housing 1 along the length direction X.

[0303] The first compartment 2013 is located in the box body 1, which means that each box body 1 has a first compartment 2013, and the first compartment 2013 corresponds to the box body 1 one by one.

[0304] The control module 202 is entirely located in the first compartment 2013 , and the first compartment 2013 and the battery compartment 11 are independent of each other in the box body 1 .

[0305] By arranging the first compartment 2013 at the end of the box body 1 along the length direction X, the battery compartment 11 and the control module 202 are relatively independent, thereby reducing the risk of interference between the battery compartment 11 and the control module 202.

[0306] In some embodiments, the second warehouse 2014 is separated from the box body 1; or the second warehouse 2014 is located on the top of the topmost container 10; or the second warehouse 2014 is hung on the side of the box body 1 along the length direction X close to the first warehouse 2013.

[0307] The second warehouse 2014 can be separated from the box body 1, and the first warehouse 2013 can be located inside the box body 1; the second warehouse 2014 can be located on the top of the topmost container 10, and the first warehouse 2013 can be located inside the box body 1; or the second warehouse 2014 can be hung on one side of the box body 1 along the length direction X or the width direction Y, and the first warehouse 2013 can be located inside the box body 1.

[0308] In the embodiment where the second warehouse 2014 is hung on one side of the box body 1 along the length direction X or the width direction Y, the second warehouse 2014 can be hung on the side of the box body 1 along the length direction X close to the second warehouse 2014; the second warehouse 2014 can also be hung on the side of the box body 1 along the length direction X away from the second warehouse 2014, or the second warehouse 2014 can be hung on the side of the box body 1 along the width direction Y.

[0309] By separating the first compartment 2013 and the second compartment 2014 , the risk of interference between the thermal management module 203 and the control module 202 is reduced, and the operational stability of the thermal management module 203 and the control module 202 is improved.

[0310] In some embodiments, please refer to FIG. 16 , which is a schematic diagram of the structure of the energy storage device 100 provided in some embodiments of the present application (showing the second access door 2017). The control module 202 is housed in the first compartment 2013 , which has a second access door 2017 located on one side of the housing 1 along the length direction X.

[0311] The second inspection door 2017 is located on one side of the box body 1 along the length direction X. The four energy storage devices 100 can be arranged in two rows and two columns, with the two rows of energy storage devices 100 arranged along the width direction Y and the two columns of energy storage devices 100 arranged along the length direction X, so that the second inspection doors 2017 of the four energy storage devices 100 are respectively located on both sides of their arrangement structure along the length direction X or along both sides of the width direction Y.

[0312] By arranging the second inspection door 2017 at the end of the box body 1 along the length direction X, the control module 202 is located in the second compartment 2014, so that the control module 202 can be inspected at the end of the box body 1 along the length direction X.

[0313] In some embodiments, an emergency stop button is provided on the second inspection door 2017 , which can disconnect the electrical connection between the battery cell 21 and the main control module 2021 , thereby cutting off the power input or output of the container 10 .

[0314] In some embodiments, the first bin 2013 is hung on one side of at least one box body 1 along the length direction X or along the width direction Y, and the second bin 2014 is placed separately from the box body 1.

[0315] The first warehouse 2013 may be mounted on one side of a container 10 along the length direction X, or on one side of a container 10 along the width direction Y. Alternatively, one first warehouse 2013 may be mounted on one side of multiple containers 10 along the length direction X, or on one side of multiple containers 10 along the width direction Y.

[0316] The first compartment 2013 and the container 10 can be fixed by bolts, hinges, welding, or by a frame.

[0317] By separating the second warehouse 2014 from the box body 1, the risk of interference between the second warehouse 2014 and the container 10 can be reduced, and the stability of use of the second warehouse 2014 and the container 10 can be improved.

[0318] In some embodiments, the container 10 includes a battery compartment 11 and a wiring harness compartment 12. Multiple battery cells 21 are housed in the battery compartment 11. The wiring harness compartment 12 is located within the housing 1 and is arranged with the battery compartment 11 along the longitudinal direction X. The wiring harness compartment 12 is provided with an opening 33, through which at least a portion of the wiring harness connecting the container 10 and the control compartment 20 passes.

[0319] 11 and 10 as examples, openings 33 are provided on the top and bottom walls of the harness compartments 12 of the two boxes 1 to facilitate connection of cables or pipes with the control compartment 20 through the harness compartment 12 and the openings 33 on the top and bottom walls.

[0320] In some embodiments, the cables connecting the first connector 10 b and the second connector 10 c and the pipes connecting the third connector 10 d and the fourth connector 10 e are both passed through the wiring harness compartment 12 .

[0321] By providing the harness compartment 12 , the harness connecting the container 10 and the control compartment 20 at least partially passes through the harness compartment 12 , thereby reducing the risk of the harness connecting the container 10 and the control compartment 20 being exposed to the outside of the container 10 and damaged.

[0322] Please refer to Figure 17, which is a schematic diagram of the structure of a container 10 provided in some embodiments of the present application. In some embodiments, the container 10 includes multiple batteries 2, which are arranged in rows and columns. The multiple batteries 2 in each row are arranged along the length direction X, and the multiple batteries 2 in each column are arranged along the height direction Z. Each battery 2 includes a thermal management component 22 and multiple battery cells 21. The container 10 also includes a main line 301 and multiple branch lines 302. The main line 301 connects the thermal management module 203 and each branch line 302. Each branch line 302 connects to the thermal management component 22 of the multiple batteries 2 in a column.

[0323] It can be understood that the main line 301 and multiple branches 302 of the container 10 form a set of piping systems 30. Each container 10 has two sets of piping systems 30 as the liquid inlet channel and liquid outlet channel of the thermal management component 22. The structure of each piping system 30 is the same. The following is an example of the liquid inlet pipeline of the container 10.

[0324] As an example, as shown in FIG17 , there are eight batteries 2 in the container 10, and the eight batteries 2 are arranged in two rows and four columns. The container 10 has a main line 301 connected to the thermal management module 203, and four branches 302 connected to the main line 301. Each branch 302 is connected to the thermal management components 22 of two batteries 2 located in the same column.

[0325] The thermal management module 203 is connected via the main line 301 , and the thermal management module 203 can provide fluid to the main line 301 , and the main line 301 provides fluid to multiple branches 302 respectively, so that the temperature of the fluid entering the thermal management component 22 is more uniform, reducing the risk of temperature runaway of the battery 2.

[0326] In some embodiments, the plurality of batteries 2 may be arranged in multiple rows, such as 2 rows, 3 rows, 4 rows, 5 rows, or 6 rows; or in multiple columns, such as 2 columns, 3 columns, 4 columns, 5 columns, or 6 columns.

[0327] In some embodiments, the thermal management components 22 in any two containers 10 can be connected in series or in parallel. For example, m containers 10 include a first container and a second container, and all thermal management components 22 in the first container are connected in series with all thermal management components 22 in the second container.

[0328] Please refer to Figure 18, which is a schematic diagram of the structure of a thermal management module 203 provided in some embodiments of the present application. In some embodiments, the container 10 includes a plurality of batteries 2, which are arranged in rows and columns. The plurality of batteries 2 in each row are arranged along the length direction X, and the plurality of batteries 2 in each column are arranged along the height direction Z. Each battery 2 includes a thermal management component 22 and a plurality of battery cells 21. The thermal management module 203 includes a pumping device 2031, a first heat exchanger 2032, a compressor 2033, a throttling device 2034, and a second heat exchanger 2036. The pumping device 2031, the first heat exchanger 2032, the thermal management component 22, and the pumping device 2031 are sequentially connected to form a cooling circulation loop. The compressor 2033, the second heat exchanger 2036, the throttling device 2034, the first heat exchanger 2032, and the compressor 2033 are sequentially connected to form a refrigerant circulation loop 203b. The components of the thermal management module 203 are independent of the battery 2 , which reduces the risk of interference between the thermal management module 203 and the battery 2 .

[0329] The thermal management module 203 includes a pumping device 2031 and a first heat exchanger 2032 . The pumping device 2031 , the first heat exchanger 2032 , the thermal management component 22 , and the pumping device 2031 are sequentially connected to form a coolant circulation loop 203 a .

[0330] It should be noted that the pumping device 2031 (also known as a water pump) is a component used to transport coolant. The first heat exchanger 2032 is a component used to exchange heat with the coolant flowing therethrough. The first heat exchanger 2032 can be, but is not limited to, a plate heat exchanger, a shell and tube heat exchanger, an air cooler, a spiral plate heat exchanger, a heat exchange tube bundle, etc. The coolant can be, but is not limited to, a mixture of ethylene glycol and water.

[0331] Under the conveying action of the pumping device 2031, the coolant can circulate in the coolant circulation loop 203a and circulate through the pumping device 2031, the first heat exchanger 2032, the thermal management component 22, and the pumping device 2031. The above connection can be a direct connection or an indirect connection via a pipeline.

[0332] By adopting the above solution, the coolant can circulate through the thermal management component 22 to directly exchange heat with the battery cell 21, thereby cooling the battery cell 21; the coolant after heat exchange with the battery cell 21 can also circulate through the first heat exchanger 2032 and exchange heat with the first heat exchanger 2032, and heat exchange the heat exchanged from the battery cell 21 to the first heat exchanger 2032, so that the coolant is cooled.

[0333] In some embodiments of the present application, the thermal management module 203 further includes a compressor 2033, a throttling device 2034, and a second heat exchanger 2036. The compressor 2033, the second heat exchanger 2036, the throttling device 2034, the first heat exchanger 2032, and the compressor 2033 are sequentially connected to form a refrigerant circulation loop 203b.

[0334] It should be noted that the above-mentioned connection can be a direct connection or an indirect connection via a pipeline. Compressor 2033 is a component that provides power for the refrigerant circulation and is capable of cooling the refrigerant. Throttling device 2034 is a component used to reduce temperature and pressure. Throttling device 2034 can be, but is not limited to, a throttle valve, an expansion valve, etc. Second heat exchanger 2036 is a component used to exchange heat with the refrigerant flowing therethrough. Second heat exchanger 2036 can be, but is not limited to, a plate heat exchanger, a shell and tube heat exchanger, an air cooler, a spiral plate heat exchanger, a heat exchange tube bundle, etc. The refrigerant has a low boiling point and heat of vaporization, can evaporate and condense at relatively low temperatures, and can achieve a cooling effect by absorbing and releasing heat. The refrigerant can be, but is not limited to, Freon, ammonia, carbon dioxide, R134A (1,1,1,2-tetrafluoroethane), R410A (Freon R-410A refrigerant), etc.

[0335] Among them, the first heat exchanger 2032 is provided in both the coolant circulation loop 203a and the first refrigerant circulation loop 203b. The first heat exchanger 2032 is internally provided with a coolant flow channel and a refrigerant flow channel. The coolant flow channel participates in forming the coolant circulation loop 203a, and is used to allow coolant to flow therein. The refrigerant flow channel participates in forming the first refrigerant circulation loop 203b, and is used to allow refrigerant to flow therein. The coolant flow channel and the refrigerant flow channel are not connected to each other to prevent the coolant and refrigerant from mixing. In the first heat exchanger 2032, the coolant and the refrigerant can exchange heat, and in particular, the heat of the coolant can be heat-exchanged with the refrigerant, so that the first heat exchanger 2032 can cool the coolant flowing therethrough.

[0336] The thermal management module 203 further includes a cooling fan 2035 , which dissipates heat from the second heat exchanger 2036 .

[0337] In some embodiments, the container 10 includes a battery cell 21 disposed in the box body 1 , and the weight of a single battery cell 21 is 5 kg to 60 kg.

[0338] The weight of a single battery cell 21 may be any one of 5 kg, 10 kg, 15 kg, 20 kg, 25 kg, 30 kg, 35 kg, 40 kg, 45 kg, 50 kg, 55 kg, 60 kg, or any value therebetween. For example, the mass of a single battery cell 21 is 30 kg.

[0339] The weight of the battery cells 21 is appropriate so that an appropriate number of batteries 2 can be placed in the box 1, and the energy density is moderate while meeting the transportation requirements.

[0340] In some embodiments, the number of battery cells 21 is between 416 and 2080. For example, the number of batteries 2 is any one of 416, 500, 600, 700, 800, 950, 1000, 2000, or 2080, or any value in between. The number of battery cells 21 refers to the number of battery cells 21 within a single box 1. The weight of each battery cell 21 and the number of battery cells 21 are appropriately balanced so that the total weight of all battery cells 21 meets transportation requirements and improves the energy density per unit area of ​​the box 1.

[0341] In some embodiments, the weight of the container 10 is M, M≤35 tons. During the lifting process of the container 10 , it is convenient to lift the relevant lifting devices and to transfer the container 10 .

[0342] For example, the weight of the container 10 may be any one of 10 tons, 15 tons, 20 tons, 25 tons, 30 tons, 35 tons, or any value in between.

[0343] In some embodiments, the weight of the container 10 is M, the total weight of the battery cells 21 in the box body 1 is M1, and (M1 / M)×100%≥60%.

[0344] (M1 / M)×100% can be 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 90%, etc.

[0345] In this way, on the one hand, the weight proportion of the battery cells 21 in the unit volume of the container 10 can be increased, thereby increasing the power capacity of the unit volume of the container 10. On the other hand, during the transportation of the container 10, more battery cells 21 that contribute to energy storage and are difficult to produce and cannot be completed at the destination are transported, while other structures can be completed at a location closer to the destination without having to be transported or with reduced transportation. After the container 10 is assembled into the energy storage device 100, this is conducive to reducing the transportation cost of the assembled energy storage device 100.

[0346] In some embodiments, (M1 / M)×100%≧80%.

[0347] (M1 / M)×100% can be 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89% or 90%, etc.

[0348] This further helps reduce the transportation cost of the assembled energy storage device 100 .

[0349] In some embodiments, the weight of the container 10 is M, and multiple batteries 2 are arranged in the box body 1. The battery 2 includes a storage box 23 (shown in Figure 17) and multiple battery cells 21. The multiple battery cells 21 are accommodated in the storage box 23. The total weight of the battery 2 is M2, 70%≤(M2 / M)×100%≤90%.

[0350] The storage box 23 may include two parts that cover each other, such as an upper cover and a bottom plate, or an upper cover and a lower box body 1, which together form a storage space for the battery cells 21. The thermal management component 22 may be part of the storage box 23 or located within the storage space.

[0351] (M2 / M)×100% can be any one of 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90% or any point value between any two of them.

[0352] When (M2 / M)×100%≥70%, the weight ratio of the battery 2 per unit volume of the container 10 can be increased, thereby improving the energy density of the container 10. When (M2 / M)×100%≤90%, the structural strength of the container 10 can be maintained. Therefore, when 70%≤(M2 / M)×100%≤90%, both the energy density and the structural strength of the container 10 are achieved, making the container 10 more practical.

[0353] In some embodiments, the volume of the container 10 is V, the total volume of the battery cells 21 in the box body 1 is V1, and (V1 / V)×100%≥30%.

[0354] The battery cell 21 includes a housing 211 , and the volume of the battery cell 21 is the volume of the housing 211 . For example, if the battery cell 21 is a square-shell battery cell 21 , the product of the length, width, and height of the square-shell battery cell 21 is the product of the length, width, and height of the housing 211 .

[0355] In an embodiment where the battery cell 21 further includes an electrode terminal 213 , the electrode terminal 213 is disposed in the outer shell 211 and partially protrudes from the outer shell 211 . The electrode terminal 213 is electrically connected to the electrode assembly 212 , and the portion of the electrode terminal 213 protruding from the outer shell 211 is not counted as part of the volume of the battery cell 21 .

[0356] (V1 / V)×100% can be 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 55%, 60%, 65% or 70%, etc.

[0357] On the one hand, the volume ratio of the battery cells 21 in the unit volume of the container 10 can be increased, thereby increasing the power capacity of the unit volume of the container 10. On the other hand, during the transportation of the container 10, more battery cells 21 that contribute to energy storage and are difficult to produce and cannot be completed at the destination are transported, while other functional components of the energy storage device 100, such as control components, can be completed at a location closer to the destination and do not need to be transported or transportation is reduced. After the container 10 is assembled into the energy storage device 100, this is conducive to reducing the transportation cost of the assembled energy storage device 100.

[0358] In some embodiments, (V1 / V)×100%≧50%.

[0359] (V1 / V)×100% can be 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 75%, 80%, 85% or 90%, etc.

[0360] This is further beneficial to reducing the transportation cost of the assembled energy storage device 100 .

[0361] In some embodiments, the volume of the container 10 is V, and multiple batteries 2 are arranged in the box body 1. The battery 2 includes a storage box 23 and multiple battery cells 21. The multiple battery cells 21 are accommodated in the storage box 23. The total volume of the battery 2 is V2, 50%≤(V2 / V)×100%≤80%.

[0362] The volume of the battery 2 is the volume of the container 23. For example, if the container 23 is a rectangular parallelepiped structure, the volume of the battery 2 is equal to the product of the length, width, and height of the container 23.

[0363] (V2 / V)×100% can be any one of the point values ​​of 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 75%, 80% or any point value between any two of them.

[0364] When (V2 / V)×100%≥50%, the volume ratio of the battery 2 per unit volume of the container 10 can be increased, thereby improving the energy density of the container 10. When (V2 / V)×100%≤80%, the container 10 can have sufficient volume for structural components to maintain the structural strength of the container 10. Therefore, when 50%≤(V2 / V)×100%≤80%, both the energy density and the structural strength of the container 10 are achieved, making the container 10 more practical.

[0365] In some embodiments, the energy of the container 10 is E, the dimension of the container 1 along the length direction X is a (shown in FIG21 ), the dimension of the container 1 along the width direction Y is b (shown in FIG21 ), 250KW / m 2 ≤E / (a×b)≤700KW / m 2 .

[0366] E / (a×b) can be 250KW / m 2 、300KW / m 2 、350KW / m 2 , 400KW / m 2 450KW / m 2 、460KW / m 2 、470KW / m 2 、480KW / m 2 、485KW / m 2 、490KW / m 2 、495KW / m 2 500KW / m 2 、510KW / m 2 、550KW / m 2 、600KW / m 2 、650KW / m 2 , 700KW / m 2 The point value of any one of them or any point value between them.

[0367] The energy E can be obtained from the nameplate of the container 10.

[0368] When E / (a×b)≥250KW / m 2When E / (a×b)≤700KW / m 2 When the power is 250KW / m 2 ≤E / (a×b)≤700KW / m 2 At the same time, the energy density of the container 10 and the mass setting of the container 10 are taken into consideration, the practicality of the container 10 is improved, and the transportation of the container 10 is also facilitated.

[0369] In some embodiments, 450KW / m 2 ≤E / (a×b)≤600KW / m 2 .

[0370] E / (a×b) can be 450KW / m 2 、455KW / m 2 、460KW / m 2 、465KW / m 2 、470KW / m 2 、475KW / m 2 、480KW / m 2 、485KW / m 2 、490KW / m 2 、495KW / m 2 500KW / m 2 、505KW / m 2 、510KW / m 2 、515KW / m 2 、520KW / m 2 、530KW / m 2 、540KW / m 2 、550KW / m 2 、600KW / m 2 The point value of any one of them or any point value between them.

[0371] As an example, E / (a×b)=490KW / m 2 The energy density of the container 10 and the mass setting of the container 10 can be further improved, thereby facilitating the transportation of the container 10 .

[0372] In some embodiments, the energy storage device 100 further includes a connecting mechanism configured to connect two containers 10 adjacent in the height direction Z. The connecting mechanism can connect two containers 10 adjacent in the height direction; it can also lock two containers 10 adjacent in the height direction Z to achieve a detachable connection between the two containers 10 adjacent in the height direction Z.

[0373] In the embodiment of the present application, the locking mechanism 101 may be a connecting mechanism.

[0374] Please refer to Figure 19, which is a schematic diagram of the structure of an energy storage device 100 provided in some embodiments of the present application (showing a locking mechanism 101). The present embodiment provides an energy storage device 100, comprising a plurality of containers 10, which are stacked in a height direction Z.

[0375] In some embodiments, the energy storage device 100 further includes a locking mechanism 101, which is configured to lock two containers 10 adjacent to each other along the height direction Z. The locking mechanism 101 includes a support member 1011, which is arranged between two adjacent containers 10 along the height direction Z; wherein, the sum of the dimensions of m1 containers 10 in the multiple containers 10 along the height direction Z and the sum of the dimensions of m1-1 support members 1011 along the height direction Z is equal to the sum of the dimensions of n standard containers 10 in the height direction Z.

[0376] The locking mechanism 101 can be used to lock two containers 10 adjacent to each other in the height direction Z by means of snap-fit ​​locking or a locking member 1012. For example, the locking mechanism 101 includes a bolt and two locking portions, each of which is provided on one of the two containers 10 adjacent to each other in the height direction Z. The bolt cooperates with the two locking portions to lock the two containers 10.

[0377] The sum of the dimensions of m1 containers 10 in the height direction Z and the sum of the dimensions of m1-1 support members 1011 in the height direction Z among the plurality of containers 10 is equal to the sum of the dimensions of n standard containers 10 in the height direction Z, which means that the sum of the dimensions of m1 containers 10 in the height direction Z and the sum of the dimensions of m1-1 support members 1011 in the height direction Z is approximately equal to the sum of the dimensions of n standard containers 10 in the height direction Z, and the approximately equal difference is m1×W1, W1≤5mm, and the height of the support member 1011 is W2, W2≤30. W1 can be any one of 0mm, 1mm, 2mm, 3mm, 4mm, and 5mm, or any value between them.

[0378] As an example, m1=2, n=1, the height h of the container 1010 is 1434 mm, W1=0 mm, the height of the support 1011W2 is 28 mm, and the corresponding height H of the standard container 10 is 2896 mm, m1×h+(m1-1)×W2=n×H; therefore, the sum of the dimensions of m1 containers 1010 along the height direction ZZ is equal to the sum of the dimensions of n standard containers 10 along the height direction ZZ.

[0379] By locking the containers 10 with the locking mechanism, the stacking of the containers 10 can be made more stable. When transporting the containers 10, m1 containers 10 are stacked and supports 1011 are provided between adjacent containers 10. This ensures that the stacking height of the m1 containers 10 is equal to the height of n standard containers 10. This ensures that the space required for transporting the m1 containers 10 is the same as the space required for transporting n standard containers 10, thereby efficiently utilizing the space occupied by the containers 10 and saving transportation costs.

[0380] It should be noted that in the embodiments of the present application, the positional relationship, matching relationship, and connection relationship between the control compartment 20 and the container 10 as well as the connection relationship between the pipes and cables described in the embodiment in which the energy storage device 100 does not include the support member 1011 are all applicable to the embodiment in which the energy storage device 100 includes the support member 1011.

[0381] Please refer to Figure 20, which is a schematic diagram of the structure of the locking mechanism 101 provided in some embodiments of the present application. In some embodiments, the locking mechanism 101 further includes a locking member 1012, and a support member 1011 is disposed between two adjacent containers 10 along the height direction Z. The locking member 1012 is rotatably disposed on the support member 1011 about an axis extending along the height direction Z, and is used to lock two adjacent containers 10 along the height direction Z.

[0382] The locking accessory 1012 may lock the two containers 10 by snapping together; or the locking accessory 1012 may lock the two containers 10 by bolting together. For example, the locking accessory 1012 is a locking rod, and threads with opposite rotation directions are provided on both sides of the locking rod extending along its length. Screw holes are provided on both containers 10. The locking rod is rotated to make the threads engage or separate with the screw holes to lock or unlock the two containers 10.

[0383] The support member 1011 is provided between two adjacent containers 10 along the height direction Z, thereby connecting the two containers 10 and buffering the fit between the two containers 10. The locking member 1012 locks the two containers 10, making the stacking of the containers 10 more stable.

[0384] In some embodiments, one of the two containers 10 adjacent to each other in the height direction Z has a first locking hole 102 (shown in FIG. 16 ), and the other has a second locking hole 103. The first locking hole 102 and the second locking hole 103 are arranged relative to each other in the height direction Z. The locking member 1012 further includes a first locking portion 10121, a second locking portion 10122 and a connecting portion 10123. The connecting portion 10123 is rotatably arranged on the support member 1011 around an axis extending in the height direction Z. The connecting portion 10123 connects the first locking portion 10121 and The second locking portion 10122, the first locking portion 10121 and the second locking portion 10122 are respectively located on both sides of the support member 1011, and the connecting portion 10123 has a first position and a second position; when the connecting portion 10123 is located at the first position, the first locking portion 10121 and the second locking portion 10122 can be inserted into or withdrawn from the first locking hole 102 and the second locking hole 103 respectively; when the connecting portion 10123 is located at the second position, the first locking portion 10121 and the second locking portion 10122 can cooperate to lock two adjacent containers 10.

[0385] The first locking portion 10121 , the second locking portion 10122 and the connecting portion 10123 may be integrally formed, or the first locking portion 10121 , the second locking portion 10122 and the connecting portion 10123 may be welded.

[0386] The first locking hole 102 and the second locking hole 103 may be waist-shaped holes of the same size, the length of the waist-shaped hole is greater than the width, the first locking portion 10121 and the second locking portion 10122 are both T-shaped blocks, the length and width of the T-shaped part of the first locking portion 10121 are both smaller than the length and width of the waist-shaped hole, and the length of the T-shaped part is greater than the width of the waist-shaped hole, and the first locking portion 10121 and the second locking portion 10122 have the same size; the first locking portion 10121 and the second locking portion 10122 can both be inserted into the corresponding first locking hole 102 and the second locking hole 103, and by rotating the connecting portion 10123, the first locking portion 10121 and the second locking portion 10122 can be respectively clamped in the first locking hole 102 and the second locking hole 103 to achieve the locking of two adjacent containers 10.

[0387] By switching the connecting portion 10123 between the first position and the second position, the locking accessory 1012 can lock or unlock two adjacent containers 10 , thereby facilitating assembly and disassembly of the two adjacent containers 10 .

[0388] In some embodiments, the support member 1011 is provided with a through hole 10111 passing through the support member 1011 along the height direction Z, and the locking accessory 1012 is rotatably inserted in the through hole 10111 around an axis extending along the height direction Z; the locking mechanism 101 includes a driving arm 1013, the driving arm 1013 is connected to the locking accessory 1012, the support member 1011 is provided in an accommodating cavity 10112 connected to the through hole 10111, the accommodating cavity 10112 passes through at least one end of the support member 1011 along a direction perpendicular to the height direction Z, and the driving arm 1013 is swingably provided in the accommodating cavity 10112.

[0389] The driving arm 1013 can be connected to the locking accessory 1012 by welding, clamping or bolting.

[0390] The accommodating cavity may extend through both ends of the support member 1011 in a direction perpendicular to the height direction Z, or may extend through only one end of the support member 1011 in a direction perpendicular to the height direction Z. The driving arm 1013 may be entirely located within the accommodating cavity 10112, and may be moved by swinging the driving arm 1013 by inserting a hand or a connecting member into the accommodating cavity 10112; the driving arm 1013 may also be partially located outside the accommodating cavity 10112, so as to facilitate swinging the driving arm 1013 for movement.

[0391] By swinging the driving arm 1013 in the accommodating cavity 10112 , the connecting portion 10123 is switched between the first position and the second position, thereby facilitating rapid locking or unlocking between two adjacent containers 10 .

[0392] In some embodiments, along the height direction Z, the heights of some of the m containers 10 are different from the heights of the other containers 10. This facilitates improving the flexibility of the capacity of the containers 10 to meet different needs.

[0393] The sum of the heights of multiple containers 10 having unequal dimensions along the height direction Z may be exactly equal to the dimensions of one or more containers 10. For example, if three containers 10 have different dimensions along the height direction Z, the sum of the dimensions of the three containers 10 along the height direction Z may be equal to the sum of the dimensions of two standard containers along the height direction Z. For another example, if five containers 10 have different dimensions along the height direction Z, the sum of the dimensions of the five containers 10 along the height direction Z may be equal to the sum of the dimensions of three standard containers along the height direction Z.

[0394] In some embodiments, the m containers 10 have the same size along the height direction Z. This simplifies the manufacturing process and reduces costs.

[0395] In some embodiments, the standard container is a 20-foot standard container, and the height of the standard container is 2896 mm, 2591 mm, or 2438 mm. That is, the sum of the dimensions of the m1 containers 10 along the height direction Z is the height of the 20-foot standard container, 2896 mm, 2591 mm, or 2438 mm.

[0396] Please refer to Figures 21 and 22. Figure 21 is a schematic diagram of the structure of a container 10 according to another embodiment of the present application; Figure 22 is a schematic diagram of the exploded structure of a battery cell 21 in the container 10 according to an embodiment of the present application. The battery cell 21 described in the embodiment of the present application includes an electrode assembly 212 and a housing 211. The housing 211 has a receiving cavity 10112, and the electrode assembly 212 is received in the receiving cavity 10112.

[0397] The outer shell 211 includes a shell 2111 and an end cover 2112. When assembling the battery cell 21, the electrode assembly 212 can be placed in the accommodating cavity 10112 first, and then the end cover 2112 is covered on the shell 2111. Then, the electrolyte is injected into the accommodating cavity 10112 through the electrolyte injection port on the end cover 2112.

[0398] Optionally, the housing 211 can also be used to accommodate electrolytes, such as electrolytes. The housing 211 can be in various structural forms.

[0399] The housing 211 can have a variety of shapes, such as a cylinder, a rectangular parallelepiped, etc. The shape of the housing 211 can be determined based on the specific shape of the electrode assembly 212. For example, if the electrode assembly 212 has a cylindrical structure, the housing 211 can also be a cylindrical structure. If the electrode assembly 212 has a rectangular parallelepiped structure, the housing 211 can also be a rectangular parallelepiped structure. In Figure 22, for example, both the housing 211 and the electrode assembly 212 have rectangular parallelepiped structures.

[0400] The material of the housing 211 can be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, etc., and the embodiment of the present application does not impose any special restrictions on this.

[0401] There may be one or more electrode assemblies 212 housed in the housing 211. In FIG22 , there are two electrode assemblies 212 housed in the housing 211.

[0402] As shown in Figures 21 and 22, an embodiment of the present application provides a container 10, including a box body 1 and a battery cell 21. The battery cell 21 is accommodated in the box body 1. The dimension a of the container 10 along the length direction X and the dimension b along the width direction Y are respectively consistent with those of a standard container, and the dimension h of the container 10 along the height direction Z is smaller than the dimension H of a standard container along the height direction Z of the container 10.

[0403] The container 10 includes a battery cell 21. The container 10 may include multiple battery cells 21, which are connected in series or in parallel to form an energy storage unit corresponding to the container 10. When in use, multiple containers 10 may be connected in series or in parallel to obtain an energy storage device 100 of corresponding power.

[0404] The container 10 includes the battery cells 21 . The container 10 may only include the battery cells 21 , or related functional components such as control components, fire protection components, etc. may be integrated into the container 10 .

[0405] The container 10 needs to be smaller than or equal to the size of a standard container during transportation. The standard container can be the size of a standard container during transportation, such as 20 feet, 30 feet, 40 feet or 45 feet, which meets the corresponding standards, and its length, width and height have corresponding dimensions respectively.

[0406] For example, according to GB / T 1413-2008, GB / T 1413-2023, and internationally accepted dimensions, for a standard container with a length of 6058 mm, its dimension H along the height direction Z may be 2591 mm, 2438 mm, less than 2438 mm, or 2896 mm, etc. For a standard container with a length of 9125 mm, its dimension H along the height direction Z may be 2896 mm, 2591 mm, less than 2438 mm, or 2438 mm, etc.

[0407] While the dimension a along the length direction X and the dimension b along the width direction Y of the container 10 are consistent with those of a standard container, this does not mean that the length and width of the container 10 are exactly the same as those of a standard container. Rather, certain errors are permitted within an acceptable range. For example, referring to GB / T 1413-2008 and GB / T 1413-2023, the difference between the dimension a along the length direction X of the container 10 and the dimension of a standard container along the length direction X of the container 10 is within a range of ±10 mm, and the difference between the dimension b along the width direction Y of the container 10 and the dimension of a standard container along the width direction Y of the container 10 is within a range of ±5 mm.

[0408] If the dimension h of the container 10 along the height direction Z is smaller than the dimension H of a standard container along the height direction Z of the container 10, 2h can be set to be less than or equal to H, or 3h can be set to be less than or equal to H, so that the height of multiple containers 10 stacked along the height direction Z is equivalent to the height H of a standard container.

[0409] Of course, the sum of the dimensions of the three containers 10 after stacking along the height direction Z can also be set to be the same as the dimension H of the two standard containers along the height direction Z, so that after the three containers 10 are stacked along the height direction Z, the dimension of the three containers 10 along the height direction Z is equivalent to the dimension of the two standard containers stacked along the height direction Z.

[0410] The container 10 provided in the embodiment of the present application has a dimension h in the height direction Z of the container 10 that is smaller than the dimension h in the height direction Z of a standard container. Therefore, the container 10 does not exceed the height of a standard container for sea or land transportation during transportation, which is beneficial to improving the convenience of the container 10 during transportation and reducing the transportation cost of the container 10 and the energy storage device 100 using the container 10.

[0411] In some embodiments, |2h-H|≤5mm.

[0412] For example, |2h-H| may be 0, 1 mm, 2 mm, 3 mm, 4 mm, or 5 mm.

[0413] On the one hand, the height of a container 10 is equivalent to half the height of a standard container, which can reduce the use of structural parts of the box body 1 and increase the weight of the battery cell 21 per unit volume; on the other hand, when two containers 10 are stacked along the height direction Z, the dimension H along the height direction Z is equivalent to that of a standard container, which is conducive to making full use of the available space along the height direction Z during transportation, reducing space waste during transportation of the container 10, and thus helping to reduce transportation costs.

[0414] In some embodiments, |3h-H|≤5mm.

[0415] For example, |3h-H| can be 0, 1 mm, 2 mm, 3 mm, 4 mm or 5 mm, etc.

[0416] On the one hand, the height of a container 10 is equivalent to one-third of the height of a standard container, which can reduce the use of structural parts of the box body 1 and increase the weight of the battery cell 21 per unit volume; on the other hand, when three containers 10 are stacked along the height direction Z, the dimension H along the height direction Z of the container 10 is equivalent to that of a standard container, which is conducive to making full use of the available space along the height direction Z during transportation, reducing space waste during transportation of the container 10, and thus helping to reduce transportation costs.

[0417] In some embodiments, the container 10 weighs less than or equal to 45 tons.

[0418] For example, the weight of the container 10 may be 10 tons, 15 tons, 20 tons, 25 tons, 30 tons, 35 tons, 40 tons or 45 tons, etc.

[0419] During the transshipment process of the container 10, relevant lifting equipment needs to be used to lift the container 10 on the container 10 or on the ground. The load capacity of the relevant lifting equipment is usually limited, and the maximum load capacity is usually 45 tons. By setting the weight of the container 10 to be less than or equal to 45 tons, the lifting of the relevant lifting equipment is facilitated during the lifting of the container 10, and the transshipment of the container 10 is facilitated.

[0420] In some embodiments, the weight of the container 10 is M, the total weight of the battery cells 21 in the box body 1 is M1, and M1 / M≥60%.

[0421] If M1 / M≥60%, then optionally, M1 / M≥60%, M1 / M≥70%, M1 / M≥80% or M1 / M≥90% can be set, and for example, M1 / M can be 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80% or 85%, etc.

[0422] It is understood that the higher the weight of the battery cells 21 within the container 1, the higher the energy storage capacity of the container 10, and the higher the energy density of the container 10. This can increase the weight ratio of the battery cells 21 per unit volume of the container 10, thereby increasing the amount of electricity per unit volume of the container 10. Furthermore, during the transportation of the container 10, more battery cells 21 that contribute to energy storage and are difficult to produce at the destination are transported. Other structures can be produced closer to the destination, eliminating the need for transportation or reducing transportation costs. This helps reduce the transportation costs of the assembled energy storage device 100 after the container 10 is assembled into the energy storage device 100.

[0423] In some embodiments, M1 / M ≥ 80%.

[0424] Alternatively, M1 / M may be 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89% or 90%, etc.

[0425] This increases the volume ratio of the battery cells 21 within the container 10, thereby increasing the amount of energy stored per unit volume of the container 10. The container 10 can carry more battery cells 21. During transportation, the container 10 can transport more battery cells 21, which are difficult to produce and contribute to energy storage, without having to transport, or with minimal transport, other functional components of the energy storage device 100. This further reduces the transportation cost of the assembled energy storage device 100 after the container 10 is assembled into the energy storage device 100.

[0426] In some embodiments, the volume of the container 10 is V, the total volume of the battery cells 21 in the box body 1 is v, and v / V ≥ 30%.

[0427] v / V ≥ 30%. Optionally, v / V ≥ 40% can be set. Exemplarily, v / V can be 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 55%, 60%, 65% or 70%, etc.

[0428] It is understandable that the more volume of the container 10 occupied by the battery cells 21, the more beneficial it is to increasing the energy storage capacity and energy storage density of the container 10. Thus, the container 10 can be loaded with fewer or no related functional components, while maximizing the number of battery cells 21. Thus, during the transportation of the container 10, more battery cells 21, which contribute to energy storage and are difficult to produce at the destination, are transported. Other functional components of the energy storage device 100, such as control components, can be produced closer to the destination, eliminating the need for transportation or reducing transportation costs. This helps reduce the transportation costs of the assembled energy storage device 100 after the container 10 is assembled into the energy storage device 100.

[0429] In some embodiments, v / V ≥ 50%.

[0430] Alternatively, v / V may be 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 75%, 80%, 85% or 90%, etc.

[0431] In this way, the container 10 can be loaded with more battery cells 21. During transportation, the container 10 can transport more battery cells 21 that are difficult to produce and contribute to energy storage, without having to transport or transporting as few other related functional components of the energy storage device 100 as possible. After the container 10 is assembled into the energy storage device 100, it is further beneficial to reduce the transportation cost of the assembled energy storage device 100.

[0432] As shown in Figures 21, 23, and 24, Figure 23 is a partial enlarged view of point B in Figure 21; Figure 24 is a partial structural schematic diagram of a step in the lifting process of the container 10 provided in an embodiment of the present application. In some embodiments, the top of the container body 1 has multiple lifting portions 22, which are configured to cooperate with the lifting device 7 to lift the container 10.

[0433] The hoisting portion 22 is located at the top of the box body 1 , and the hoisting portion 22 can be above the box body 1 along the height direction Z. The hoisting portion 22 can be integrally formed with the box body 1 , or a relevant hoisting portion 22 can be specially provided on the top of the box body 1 .

[0434] Optionally, the box body 1 may have one or more lifting parts 22 , and the multiple lifting parts 22 may be arranged at multiple positions to facilitate lifting of the container 10 .

[0435] After the container 10 is hoisted, the hoisting portion 22 on the top of the container 10 can cooperate with the container 10 above it in the height direction Z to achieve position-limiting cooperation between two adjacent containers 10.

[0436] The lifting part 22 can be any structure that can carry the container 10 and can cooperate with the hook and other structures of the sling 7, so as to lift the container 10 through the sling 7 to facilitate the stacking of the container 10 along the height direction Z, or to facilitate the lifting operation of the container 10 during transportation.

[0437] As shown in Figures 24 to 27, Figure 25 is a partial structural diagram of another step in the lifting process of the container 10 provided in an embodiment of the present application; Figure 26 is a partial structural diagram of another step in the lifting process of the container 10 provided in an embodiment of the present application; Figure 27 is a partial structural diagram of another step in the lifting process of the container 10 provided in an embodiment of the present application. In some embodiments, the lifting portion 22 includes a load-bearing portion 221, a receiving groove 222, and an opening 33. The receiving groove 222 is located inside the load-bearing portion 221, and the opening 33 connects the receiving groove 222 with the outside of the receiving groove 222. The opening 33 is located at the top of the load-bearing portion 221.

[0438] During the lifting process, the lifting head of the lifting device 7 can be passed through the opening 33 into the accommodating groove 222 , and then the lifting head of the lifting device 7 is rotated to cooperate with the load-bearing portion 221 to lift the container 10 .

[0439] The shape of the opening 33 can be a long strip, a circle, etc., or of course it can also be an irregular shape, which can be set according to actual needs.

[0440] Therefore, the hoisting portion 22 includes a bearing portion 221 , a receiving groove 222 and an opening 33 . The hoisting portion 22 has a simple structure, which facilitates the hoisting of the container 10 .

[0441] In some embodiments, the opening 33 may be the first locking hole 102 or the second locking hole 103 .

[0442] Optionally, as shown in FIG. 21 , in some embodiments, four hoisting portions 22 are provided on the top of the box body 1 , and the four hoisting portions 22 are arranged diagonally in pairs.

[0443] In this way, during the lifting process of the container 10, the four lifting parts 22 are lifted to facilitate maintaining a stable posture of the container 10. This makes it easier for the container 10 to cooperate and align with the container 10 below, thereby facilitating the lifting and stacking operations of the container 10.

[0444] As shown in Figure 28, Figure 28 is a schematic diagram of the structure of two adjacent containers 10 of an energy storage device 100 provided in an embodiment of the present application. In some embodiments, the bottom of the container 1 has a limit pin 41, which is used to cooperate with the container 1 of the adjacent container 10 to limit the position.

[0445] In this way, in the process of stacking the containers 10 along the height direction Z, the limit pins 41 can be used to limit the two adjacent containers 10 along the height direction Z to limit the displacement of the two adjacent containers 10 along the direction intersecting with the height direction Z, thereby reducing the risk of the two adjacent containers 10 moving relative to each other.

[0446] In some embodiments, the box 1 contains a plurality of batteries 2 arranged in rows and columns, and each battery 2 includes a plurality of battery cells 21 .

[0447] The battery 2 can be a battery 2 module or a battery 2 pack. In this way, multiple battery cells 21 are connected in series or in parallel to form a battery 2. Multiple batteries 2 are arranged in rows and columns and connected in series or in parallel to form a higher-power energy storage unit, which is conducive to making full use of the space in the box 1 to place more battery cells 21. This is conducive to improving the power and energy density of the container 10.

[0448] Continuing to refer to FIG. 21 , in some embodiments, the housing 1 includes a frame 13 and a maintenance door 14 . The maintenance door 14 is movably connected to the frame 13 to open or close the maintenance door 14 .

[0449] The maintenance door 14 is movably connected to the frame 13 , so that the maintenance door 14 can be detached from the frame 13 or can be rotated relative to the frame 13 to open or close the maintenance door 14 .

[0450] The box body 1 is provided with a maintenance door 14 , and the maintenance door 14 is movably connected to the frame 13 . In the event of a failure of the container 10 during operation, the components in the container 10 can be replaced or repaired by opening the maintenance door 14 .

[0451] As shown in Figure 29, Figure 29 is a schematic structural diagram of an energy storage device 100 provided in some embodiments of the present application. The energy storage device 100 provided in accordance with an embodiment of the present application includes the container 10 provided in any of the above embodiments.

[0452] The energy storage device 100 provided in the embodiment of the present application has the same technical effects as the container 10 provided in any of the above embodiments, and thus will not be described in detail here.

[0453] In some embodiments, the energy storage device 100 includes m containers 10, where m is a positive integer greater than or equal to 2, and the m containers 10 are stacked along the height direction Z, |h1+…+hm-nH|≤5n (mm), where h1,… and hm are respectively the dimensions of the m containers 10 along the height direction Z, and n is a positive integer.

[0454] The energy storage device 100 includes m containers 10 stacked along the height direction Z. The dimensions of each container 10 along the height direction Z are h1, ..., and hm, respectively. Optionally, h1 to hm may all be equal, or all unequal. Of course, at least two of h1 to hm may also be set to be equal.

[0455] Generally, during transportation, the error range of the difference between the allowable height of the transported goods and the height of a single standard container is within the range of -5mm to 0mm. In this way, the space in the height direction Z allowed during transportation can be fully utilized, and the requirements of the container 10 during transportation can be met.

[0456] Exemplarily, m can be set to 2 and n to 1, or m can be set to 3 and n to 2. Of course, m and n can also be other combinations.

[0457] |h1+…+hm-nH|≤5n (mm). This means that when the energy storage device 100 is stacked in the height direction Z, it is equivalent to the height dimension of n standard containers stacked in the height direction Z, and the absolute value of the height difference between the total height of the energy storage device 100 (h1+…+hm) and the total height nH of the n standard containers stacked in the height direction Z is less than or equal to 5n millimeters. In other words, when multiple containers 10 are stacked in the height direction Z, the stacked energy storage device 100 is equivalent to the height dimension of n standard containers stacked in the height direction Z, and the total height of the energy storage device 100 and the height dimension of the n standard containers stacked in the height direction Z meet the relevant error criteria.

[0458] Therefore, setting |h1+…+hm-nH|≤5n(mm) helps fully utilize the available loading space during transportation and meets relevant error requirements, so that the height dimension of m containers 10 stacked in the height direction Z is equivalent to the height dimension of n standard containers in the height direction Z. This helps further reduce the transportation cost of the energy storage device 100.

[0459] In some embodiments, n≤8.

[0460] Alternatively, n may be 8, 7, 6, 5, 4, 3, 2 or 1.

[0461] Setting n to be less than or equal to 8 means that the energy storage device 100 can be stacked in standard containers in a maximum of 8 layers during transportation, so that relevant load requirements can be met during transportation.

[0462] In some embodiments, m≤12.

[0463] Alternatively, m can be 12, 11, 10, 9, 8, 7, 6, 5, 4, 3 or 2.

[0464] Setting m≤12 means that the energy storage device 100 can stack a maximum of 12 containers 10 along the height direction Z. This helps improve the structural stability of the energy storage device 100 and reduces the load-bearing capacity of the bottom container 10, thereby reducing the load-bearing capacity of the container 10.

[0465] In some embodiments, m≤8.

[0466] Alternatively, m can be 8, 7, 6, 5, 4, 3 or 2.

[0467] In this way, the energy storage device 100 can be stacked with a maximum of 8 containers 10 along the height direction Z, which is beneficial to further improve the structural stability of the energy storage device 100 and further reduce the demand for the carrying capacity of the containers 10.

[0468] In some embodiments, two adjacent containers 10 along the height direction Z are welded, clamped, or connected via a fixing member 4 .

[0469] In some embodiments, at least a portion of the control compartment 20 is welded, clamped, or connected to the adjacent container 10 along the height direction Z by a fixing member 4. This helps reduce the risk of the control compartment 20 and the container 10 moving relative to each other after stacking, thereby improving the structural stability of the energy storage device 100.

[0470] The fixing member 4 may be at least one of a bolt, a nut, a pin, a screw or a rivet, etc. Of course, the fixing member 4 may also include a fixing plate, etc., so as to fix and connect two adjacent containers 10 in the height direction Z.

[0471] Two adjacent containers 10 along the height direction Z are connected by a fixing member 4. The fixing member 4 can be used to limit the two adjacent containers 10 along the height direction Z, which is beneficial to reducing the risk of the two adjacent containers 10 moving with each other after stacking is completed, and further beneficial to improving the structural stability of the energy storage device 100.

[0472] As shown in Figures 28 and 29, in some embodiments, multiple containers 10 include a first container and a second container, the first container is located above the second container, a limit pin 41 is provided at the bottom of the first container, and a limit hole 91 is provided at the top of the second container, and the limit pin 41 is engaged with the limit hole 91.

[0473] The container 10 includes a first container and a second container. The same container 10 is the first container relative to the container 10 below it, and the second container relative to the container 10 above it. That is, the same container 10 can be both the first container and the second container. In other words, a limit pin 41 can be provided on the bottom of the container 10, and a limit hole 91 can be provided on the top of the container 10.

[0474] In this way, the two adjacent containers 10 along the height direction Z can achieve the purpose of limiting the relative movement of the two adjacent containers 10 by using a simple structure through the cooperation between the limiting pin 41 and the limiting hole 91.

[0475] The limiting hole 91 on the top of the second container can be an opening 33 for lifting the container 10. In this way, during the lifting stage of the container 10, the opening 33 is used to lift the container 10. After the lifting of the container 10 is completed, the opening 33 on the top of the box body 1 is used to cooperate with the limiting pin 41 at the bottom of the adjacent upper container 10 to achieve the limitation of the two adjacent containers 10. This is conducive to simplifying the structure of the container 10.

[0476] As shown in Figures 30, 31, and 32, Figure 30 is a schematic diagram of the structure of two adjacent containers 10 cooperating in another energy storage device 100 provided in an embodiment of the present application; Figure 31 is a schematic diagram of the structure of two adjacent containers 10 cooperating in another energy storage device 100 provided in an embodiment of the present application; and Figure 32 is a schematic diagram of the structure of the limit pin 41 in Figure 31. In some embodiments, a first limit member 8 is provided at the bottom of the first container, and the first limit member 8 has a limit groove 81. A second limit member 9 is provided at the top of the second container, and the second limit member 9 has a limit hole 91. The ends of the limit pin 41 are respectively engaged with the limit groove 81 and the limit hole 91.

[0477] The second limiting member 9 may be the aforementioned hoisting portion, and the limiting hole 91 may be the aforementioned opening 33. The limiting hole 91 may also be a hole provided on the box body 1 of the container 10.

[0478] As shown in Figures 31 and 32, the stop pin 41 may include a body 42 and a flange 43 disposed in the middle of the body 42. The flange 43 protrudes from the body 42 and surrounds the body 42. The body 42 is smaller than the size of the stop slot 81 and the size of the stop hole 91, so that the ends of the body 42 extend into the stop slot 81 and the stop hole 91, respectively. The flange 43 is larger than the size of the stop slot 81 and the size of the stop hole 91, so that the flange 43 is clamped between the first stop member 8 and the second stop member 9.

[0479] In this way, during the stacking process of the containers 10 along the height direction Z, the limit pin 41 cooperates with the limit groove 81 of the upper container 10 between the two adjacent containers 10, and cooperates with the limit hole 91 of the lower container 10 between the two adjacent containers 10. In this way, the purpose of limiting the relative movement of the two adjacent containers 10 is achieved through a simple structure.

[0480] As shown in FIG. 29 , in some embodiments, the limiting pin 41 may be integrally formed with the first limiting member 8 .

[0481] As shown in Figure 33, Figure 33 is a schematic diagram of the structure of another energy storage device 100 provided in an embodiment of the present application. In some embodiments, the energy storage device 100 further includes an electrical compartment 5 and electrical components 51. The electrical components 51 are housed in the electrical compartment 5, which is disposed outside the container 10. The electrical components 51 are electrically connected to the battery cells 21 of the multiple containers 10 of the energy storage device 100.

[0482] The electrical components 51 are electrically connected to the battery cells 21 of multiple containers 10 of the energy storage device 100 , and the electrical components 51 in the electrical compartment 5 are connected to the battery cells 21 of multiple containers 10 to control the normal operation of the battery cells 21 in the multiple containers 10 .

[0483] The electrical connection between the electrical component 51 and the battery cell 21 can be a direct connection or an indirect connection, a strong electrical connection, or a signal connection. For example, a connection line or a signal acquisition component electrically connected to the battery cell 21 can be set in the container 10, and a related connection interface can be set on the box body 1. The electrical component 51 is electrically connected to the battery cell 21 through the related connection interface to collect the working information of the battery cells 21 in multiple containers 10 and control the normal circulation of the related battery cells 21.

[0484] The electrical component 51 can be one or more of a general control component or a main control component, etc. The electrical component 51 is housed in the electrical warehouse 5, and the electrical warehouse 5 is separated from the container 10 of the energy storage device 100. In this way, the electrical component 51 does not occupy the weight and volume of the container 10, and can be manufactured and transported separately from the container 10, which is beneficial to reducing the transportation cost of the energy storage device 100.

[0485] In some embodiments, the electrical component 51 is the control module 202 , and the electrical compartment 5 is a portion of the compartment body 201 that accommodates the control module 202 .

[0486] In some embodiments, the energy storage device 100 may further include firefighting components for extinguishing fires in each container 10. The firefighting components may include fire extinguishers, firefighting pipes, nozzles, fire detectors, and other components. The firefighting control module 2024 is configured to control the firefighting components for extinguishing fires in each container 10.

[0487] As shown in FIG33 , in some embodiments, the energy storage device 100 further includes a water cooling unit 6 , which is disposed outside the container 10 . The water cooling unit 6 is configured to perform heat exchange with the battery cells 21 within the multiple containers 10 of the energy storage device 100 .

[0488] In some embodiments, the water cooling unit 6 is the thermal management module 203 .

[0489] In this way, relevant pipelines can be set in the container 10, and pipeline interfaces can be set on the box body 1. The water cooling unit 6 is connected to the pipeline interfaces of multiple containers 10 to supply high-temperature or low-temperature fluid to the container 10 through the water cooling unit 6, thereby realizing heat exchange with the battery cells 21 in the container 10.

[0490] The water cooling unit 6 is arranged outside the container 10 . The water cooling unit 6 does not occupy the weight and volume of the container 10 and can be manufactured and transported separately from the container 10 , which is beneficial to further reduce the transportation cost of the energy storage device 100 .

[0491] As shown in Figures 28 to 33, in some embodiments, an energy storage device 100 includes m containers 10, a stop pin 41, an electrical compartment 5, electrical components 51, and a water-cooling unit 6. m is a positive integer greater than or equal to 2. The m containers 10 are stacked along a height direction Z, with |h1+…+hm-nH|≤5n (mm), where h1, …, and hm are the dimensions of the m containers 10 along the height direction Z, and n is a positive integer. The container 10 includes a housing 1 and battery cells 21, which are housed within the housing 1. The dimensions of the container 10 along the length direction X and the width direction Y are consistent with those of a standard container, and the dimension h of the container 10 along the height direction Z is smaller than the dimension H of a standard container along the height direction Z. The electrical components 51 are housed within the electrical compartment 5 and are electrically connected to the battery cells 21 of the multiple containers 10 of the energy storage device 100. The water-cooling unit 6 is configured to exchange heat with the multiple containers 10 of the energy storage device 100. The weight of the container 10 is less than or equal to 45 tons. The weight of the container 10 is M, the total weight of the battery cells 21 in the box body 1 is M1, and M1 / M ≥ 60%. The volume of the container 10 is V, the total volume of the battery cells 21 in the box body 1 is v, and v / V ≥ 30%. The box body 1 includes a frame 13 and a maintenance door 14, and the maintenance door 14 is movably connected to the frame 13 to open or close the maintenance door 14. The bottom of the box body 1 has a limit groove 81, and the limit pin 41 cooperates with the upper limit groove 81 of the two adjacent containers 10 and cooperates with the opening 33 of the lower container 10 to limit the relative displacement of the two adjacent containers 10 along the direction intersecting the height direction Z.

[0492] Please refer to Figure 34, which is a schematic diagram of the structure of an energy storage device 100 provided in some embodiments of the present application (showing a silo 201). Embodiments of the present application provide an energy storage device 100, comprising a control silo 20 and a container 10 provided in any of the above embodiments. The control silo 20 comprises a silo 201, a control module 202, and a thermal management module 203. The control module 202 is used to electrically control the battery cells 21, and the thermal management module 203 is used to manage the temperature of the battery cells 21. The silo 201 and the container 10 are arranged along the height direction Z of the container 10. The thermal management module 203 and / or at least part of the control module 202 are disposed within the silo 201. The dimension of the silo 201 along its length direction X is consistent with the dimension of a standard container in the length direction X. The dimension of the silo 201 along its width direction Y is consistent with the dimension of a standard container in the width direction Y. The dimension of the silo 201 along its height direction Z times the dimension of the standard container in the height direction Z is equal to the dimension of the standard container in the height direction Z, where p is a positive integer and 2≤p≤5.

[0493] "p times the size of the warehouse body 201 in the height direction Z is equal to the size of a standard container in the height direction Z" means that p times the size of the warehouse body 201 in the height direction Z is approximately equal to the size of a standard container in the height direction Z. When the difference between the p times the size of the warehouse body 201 and the size of a standard container in the height direction Z is within a certain range, the sizes are considered to be approximately equal. The approximately equal difference is W, where W ≤ p × 35mm - 30mm. For example, if p = 3, the approximately equal difference W can be up to 75mm. When the difference between the sum of the heights of the three warehouse bodies 201 and the size of a standard container is within 75mm, the sum of the heights of the three warehouse bodies 201 in the height direction Z is equal to the size of a standard container in the height direction Z.

[0494] The height dimension of the warehouse body 201 along the height direction Z can be 1 / 2, 1 / 3, 1 / 4, or 1 / 5 of the height dimension of a standard container along the height direction Z. For example, if the height dimension of the warehouse body 201 along the height direction Z is 1 / 3 of the height dimension of a standard container along the height direction Z, then the height dimension of the warehouse body 201 tripled along the height direction Z is equal to the height dimension of a standard container along the height direction Z.

[0495] By providing a control module 202, the control module 202 can control the input or output of electrical energy of the battery cell 21, thereby achieving electrical control of the battery cell 21. By providing a thermal management module 203, the thermal management module 203 can manage the temperature of the battery cell 21, thereby reducing the risk of temperature runaway of the battery cell 21. The warehouse body 201 can integrate the control module 202 and the thermal management module 203, which facilitates the maintenance of the control module 202 and the thermal management module 203. The dimension of the warehouse body 201 along the height direction Z is smaller than the dimension of a standard container along the height direction Z. During transportation, the warehouse body 201 does not exceed the height along the height direction Z of the corresponding standard container for sea or land transportation, which facilitates the transportation convenience of the warehouse body 201. The dimensions of the warehouse body 201 along the length direction X and the dimensions of the warehouse body 201 along the width direction Y are both consistent with those of a standard container, so that the horizontal area occupied by the warehouse body 201 during transportation is consistent with that of a standard container. The dimensions of p warehouse bodies 201 along the height direction Z are the dimensions of a standard container along the height direction Z, so that the space occupied by p warehouse bodies 201 when stacked is the same as the space occupied by a standard container, thereby improving the utilization rate of the space where the warehouse bodies 201 are placed, making full use of the available space along the height direction Z during transportation, reducing space waste during transportation of the warehouse body 201, reducing the transportation cost of the warehouse body 201 and the energy storage device 100 using the warehouse body 201, and thus reducing the use cost of the energy storage device 100.

[0496] In some embodiments, when p warehouse bodies 201 are stacked for assembly or for land or sea transportation, a support member 1011 may also be provided between two adjacent warehouse bodies 201 along the height direction Z. The p warehouse bodies 201 may be stacked so that the sum of the dimensions of the p warehouse bodies 201 along the height direction Z is the same as the dimension of a standard container; or the p warehouse bodies 201 may be stacked and a support member 1011 is provided between every two adjacent warehouse bodies 201, and the sum of the dimensions of the p-1 support members 1011 along the height direction Z and the sum of the dimensions of the p warehouse bodies 201 along the height direction Z is the same as the dimension of a standard container.

[0497] A support member 1011 may be provided between every two warehouse bodies 201 ; a support member 1011 may be provided between only some adjacent warehouse bodies 201 ; or no support member may be provided between all adjacent warehouse bodies 201 .

[0498] In the embodiment where the warehouse body 201 and the container 10 are stacked along the height direction Z, a support member 1011 may be provided between the warehouse body 201 and the container 10 , or may not be provided.

[0499] In some embodiments, some control modules 202 are disposed in the warehouse body 201 , and the remaining control modules 202 are disposed in the container 10 .

[0500] In some embodiments, the control module 202 includes a main control module 2021 , a power distribution module 2023 , a general control module 2022 and a fire control module 2024 . The main control module 2021 , the general control module 2022 and the fire control module 2024 are all electrically connected to the power distribution module 2023 .

[0501] An embodiment of the present application provides an energy storage system 2000 , including a power conversion device and the energy storage device 100 provided in any one of the above embodiments. The power conversion device is used to electrically connect the power generation device 3000 and the energy storage device 100 or the container 10 .

[0502] Please refer to Figure 35, which is a schematic diagram of the structure of the control compartment 20, power conversion device 300, and transformer 500 provided in some embodiments of the present application. In some embodiments, the energy storage system 2000 also includes a transformer 500, which is electrically connected to the power conversion device and is used to electrically connect to the power grid; at least two containers 10 are arranged along the length direction X; the compartment body 201 is separated from the box body 1, and the control compartment 20, power conversion device 300, and transformer 500 are arranged along the length direction X. The total span of the control compartment 20, power conversion device 300, and transformer 500 along the length direction X is less than or equal to the total span of two adjacent containers 10 along the length direction X.

[0503] The control compartment 20, power conversion device 300, and transformer 500 are arranged along the length direction X. Along the length direction X, the control compartment 20 may be located between the power conversion device 300 and the transformer 500; the power conversion device 300 may be located between the control compartment 20 and the transformer 500; or the transformer 500 may be located between the power conversion device 300 and the control compartment 20. One of the control compartment 20, power conversion device 300, and transformer 500 may offset the other two; one of the control compartment 20, power conversion device 300, and transformer 500 may be separated from the other two; or the control compartment 20, power conversion device 300, and transformer 500 may be separated in pairs.

[0504] The total span of the control compartment 20, the power conversion device 300 and the transformer 500 along the length direction X refers to the total size of the control compartment 20, the power conversion device 300 and the transformer 500 along the length direction X; when there is no gap between the three, the total span is the sum of the sizes of the three along the length direction X; when there is a gap between the three, the total span is the sum of the sizes of the three along the length direction X plus the sum of the sizes of the gaps along the length direction X.

[0505] The total span of two adjacent containers 10 along the length direction X refers to the total dimensions of any two adjacent containers 10 in the multiple containers 10 along the length direction X. When there are more than three containers 10, there are multiple groups of adjacent containers 10, and the minimum total dimensions along the length direction X in the multiple groups is the total span of the two adjacent containers 10 along the length direction X. When there is no gap between two adjacent containers 10, the total span is the sum of their dimensions along the length direction X. When there is a gap between them, the total span is the sum of their dimensions along the length direction X plus the sum of the dimensions of the gap along the length direction X.

[0506] As an example, as shown in FIG35 , the total span of the control compartment 20 , the power conversion device 300 and the transformer 500 along the length direction X is L1 , and the total span of two adjacent containers 10 along the length direction X is L2 , and L1 is smaller than L2 .

[0507] By making the sum of the dimensions of the control compartment 20, the power conversion device 300, and the transformer 500 along the length direction X less than or equal to the sum of the dimensions of two standard containers along the length direction X, the control compartment 20, the transformer 500, and the power conversion device 300 can occupy only the space of two standard containers when transported together, thereby reducing transportation costs.

[0508] In some embodiments, the energy storage system 2000 also includes a transformer 500, which is electrically connected to the power conversion device and is used to be electrically connected to the power grid; at least two containers 10 are arranged along the length direction X; the control compartment 20 includes a first compartment 2013 and a second compartment 2014, the first compartment 2013 is connected to the box body 1, and the second compartment 2014 is separated from the box body 1, the second compartment 2014, the power conversion device 300 and the transformer 500 are arranged along the length direction X, and the total span of the second compartment 2014, the power conversion device 300 and the transformer 500 along the length direction X is less than or equal to the total span of the two adjacent containers 10 along the length direction X.

[0509] The second compartment 2014, the power conversion device 300, and the transformer 500 are arranged along the length direction X. Along the length direction X, the second compartment 2014 may be located between the power conversion device 300 and the transformer 500; the power conversion device 300 may be located between the second compartment 2014 and the transformer 500; or the transformer 500 may be located between the power conversion device 300 and the second compartment 2014. One of the second compartment 2014, the power conversion device 300, and the transformer 500 may be offset from the other two; one of the second compartment 2014, the power conversion device 300, and the transformer 500 may be separated from the other two; or the second compartment 2014, the power conversion device 300, and the transformer 500 may be separated from each other.

[0510] The total span of the second compartment 2014, the power conversion device 300, and the transformer 500 along the length direction X refers to the total dimensions of the second compartment 2014, the power conversion device 300, and the transformer 500 along the length direction X. When there is no gap between the three, the total span is the sum of the dimensions of the three along the length direction X. When there is a gap between the three, the total span is the sum of the dimensions of the three along the length direction X plus the sum of the dimensions of the gaps along the length direction X.

[0511] The total span of two adjacent containers 10 along the length direction X refers to the total dimensions of any two adjacent containers 10 in the multiple containers 10 along the length direction X. When there are more than three containers 10, there are multiple groups of adjacent containers 10, and the minimum total dimensions along the length direction X in the multiple groups is the total span of the two adjacent containers 10 along the length direction X. When there is no gap between two adjacent containers 10, the total span is the sum of their dimensions along the length direction X. When there is a gap between them, the total span is the sum of their dimensions along the length direction X plus the sum of the dimensions of the gap along the length direction X.

[0512] By making the sum of the dimensions of the second compartment 2014, the power conversion device 300, and the transformer 500 along the length direction X less than or equal to the sum of the dimensions of two standard containers along the length direction X, the second compartment 2014, the transformer 500, and the power conversion device 300 can occupy only the space of two standard containers when transported together, thereby reducing transportation costs.

[0513] An embodiment of the present application provides a charging network 1000, including a charging pile 200 and an energy storage device 100 provided in any of the above embodiments. The charging pile 200 is electrically connected to the energy storage device 100 and a container 10. The energy storage device 100 and the container 10 are used to provide electrical energy to the charging pile 200.
