Description

Technical Field

[0001] This application relates to the field of energy storage technology, and in particular to an energy storage device, container, energy storage system and charging network. Background Technology

[0002] Containerized energy storage systems are complete energy storage devices that highly integrate battery cells, electrical equipment, temperature control systems, and other components into a container.

[0003] Currently, containerized energy storage systems suffer from problems such as large weight, high cost, and transportation difficulties. Utility Model Content

[0004] This application provides an energy storage device, a container, an energy storage system, and a charging network, which helps to reduce weight, cost, and transportation difficulty.

[0005] A first aspect of this application provides an energy storage device, the energy storage device comprising: a container including a detachably connected body and a support member, the body opening downwards along the direction of gravity, the support member closing the opening, the body and the support member forming a receiving cavity; a battery device disposed within the receiving cavity and supported by the support member; and a control device connected to the battery device for thermal management and / or electrical management of the battery device.

[0006] In the energy storage device of this application embodiment, the container is configured as a split structure including a detachably connected box body and a load-bearing component. The weight of the battery device is mainly supported by the load-bearing component, which reduces the structural strength requirements of the box body, simplifies the box body structure, reduces its weight, and consequently helps to reduce the overall weight and cost of the energy storage device. The transportation difficulty is also reduced accordingly due to the weight reduction. On the other hand, this configuration allows users to disassemble the energy storage device, transport it to the site, and then assemble it, thereby further reducing transportation difficulty. Furthermore, in this embodiment, users are allowed to place the load-bearing component first when assembling the energy storage device, then assemble the battery device and other related structures onto the load-bearing component, and finally assemble the box body onto the load-bearing component. Compared with the assembly method in related technologies that uses a box door for assembly, this assembly method provides a larger assembly operation space (reducing the obstruction caused by the box body), making it easier for users to operate large assembly mechanisms (such as forklifts, lifting structures, etc.) for assembly, thereby helping to reduce the assembly difficulty of the energy storage device and improve assembly efficiency.

[0007] In some embodiments, the control device is at least partially supported by the carrier.

[0008] In this embodiment, the carrier further assumes the function of carrying the control device. This helps to improve the assembly stability of the control device and the reliability of the energy storage device. On the other hand, it also makes it possible for the control device, battery device and carrier to move together as a whole, reducing the difficulty of later maintenance.

[0009] In some embodiments, at least a portion of the control device is supported on the carrier and located within the receiving cavity, or at least a portion of the control device is supported on the carrier and located outside the receiving cavity.

[0010] By configuring at least a portion of the control device to be supported by a carrier and located within the housing cavity, the container can provide certain limits and / or protection for this portion of the control device. This helps reduce the self-protection requirements of this portion of the control device and / or simplify the related limiting structure, thereby further simplifying the structure of the energy storage device and reducing costs. By configuring at least a portion of the control device to be supported by a carrier and located outside the housing cavity, on the one hand, it helps improve the convenience of user operation and / or maintenance of the control device (operation can be performed directly outside the container), and reduces the impact on the battery devices within the housing cavity during maintenance. On the other hand, it helps reduce the number of openings in the container used to accommodate the control device, thereby reducing the difficulty and cost of sealing the container and better meeting the sealing requirements of the battery devices.

[0011] In some embodiments, the control device includes an electronic control device and a thermal management device. The electronic control device is connected to the battery device to perform electrical management of the battery device, and the thermal management device is connected to the battery device to perform thermal management of the battery device. Both the electronic control device and the thermal management device are carried on the carrier.

[0012] In this embodiment, by setting both the electronic control device and the thermal management device to be supported by a support component, it helps to further improve the reliability of the energy storage device and also helps to further reduce the difficulty of later maintenance.

[0013] In some embodiments, the control device includes a fire control device supported on the support member, or the fire control device is supported on at least one of the electrical control device and the thermal management device.

[0014] In this embodiment, by mounting the fire control device on a support member, the assembly difficulty is reduced. By mounting the fire control device on an electrical control device and / or a thermal management device, space reuse in the direction of gravity is achieved, thereby improving space utilization.

[0015] In some embodiments, the container has at least one first door opening corresponding to the battery device, the container includes a first door body disposed in the first door opening, and / or, at least a portion of the control device is located within the receiving cavity, the container has at least one second door opening corresponding to the control device, and the container includes a second door body disposed in the second door opening.

[0016] By providing a first doorway, users can open the first door and perform simple maintenance on the battery unit during actual use, thus reducing the difficulty and cost of maintaining the energy storage device. By providing a second doorway, users can open the second door to maintain the control unit during actual use, and the second door can also be used to maintain the container's seal during normal operation.

[0017] In some embodiments, the container includes an insulation structure disposed on at least one of the container body and the carrier; and / or, the container includes a sealing structure disposed between the container body and the carrier; and / or, the container includes a lifting structure disposed on at least one of the container body and the carrier.

[0018] By incorporating an insulation structure, the container's insulation performance is improved, thus reducing the insulation requirements on the battery unit itself. This allows for a simplification of the battery unit's structure, lowering the cost of the energy storage device while increasing energy density. Similarly, by incorporating a lifting structure into the container and / or load-bearing components, the container and / or load-bearing components can be installed and dismantled using lifting methods. Furthermore, the entire container can be moved using lifting (i.e., moving the container as a whole while it is mounted on the load-bearing components), further reducing the difficulty of transporting, assembling, and maintaining the energy storage device.

[0019] In some embodiments, the container includes a liquid guide disposed on the carrier, one end of the liquid guide opening into the receiving cavity and the other end opening onto the surface of the carrier opposite to the receiving cavity.

[0020] By installing a liquid guiding component on the support, the condensate in the containment cavity can be drained out of the containment cavity by gravity, thus improving the reliability of the energy storage device.

[0021] In some embodiments, the battery device includes a battery housing and a battery cell assembly, the battery housing having a mounting cavity in which the battery cell assembly is disposed; or, the battery device includes a support mechanism and a battery cell assembly, the battery cell assembly being supported by the support mechanism and exposed in the receiving cavity.

[0022] By configuring the battery device to include a battery housing and housing the individual battery cells within the housing's mounting cavity, the protection of the individual battery cells is enhanced, thereby improving the reliability of the energy storage device. Compared to the battery housing, the supporting structure is simpler in structure, lower in cost, occupies less space, and is easier to assemble. This helps reduce the cost and assembly difficulty of the energy storage device and increases its energy density.

[0023] In some embodiments, the container includes a support assembly fixed to the carrier and extending in the direction of gravity, and a plurality of the battery devices are distributed in the support assembly in the direction of gravity.

[0024] In this embodiment, multiple battery devices are distributed along the direction of gravity on the supporting component. This helps to reduce the interaction force between two adjacent battery devices along the direction of gravity and helps to improve the stability of the battery devices stacked along the direction of gravity, thereby helping to improve the reliability of the energy storage device.

[0025] In some embodiments, the support component is detachably connected to the carrier.

[0026] In this embodiment, by setting the support component to be detachably connected to the carrier, it helps to further reduce the difficulty of transportation. For example, the box, carrier, support component and battery device can be transported to the site separately and then assembled. On the other hand, this setting allows users to detach one support component from the carrier and install another support component onto the carrier. In this way, the arrangement and number of battery devices in the energy storage device can be changed by changing the support component, providing more possibilities for the expansion and structural changes of the energy storage device.

[0027] In some embodiments, the support assembly includes a plurality of fixed posts extending along the direction of gravity, the plurality of fixed posts being distributed at least along a first direction, the battery device being connected to the fixed posts at both ends along the first direction, the first direction being perpendicular to the direction of gravity.

[0028] In this embodiment, the support component of this structural form can provide reliable support for the battery device while reducing the space occupied in the cavity, thereby helping to improve the energy density of the energy storage device.

[0029] In some embodiments, the energy storage device includes a plurality of battery clusters, each battery cluster including a plurality of battery devices arranged along the direction of gravity, the plurality of battery clusters being arranged along a first direction perpendicular to the direction of gravity, and the fixing post including a first fixing post disposed between two adjacent battery clusters, the first fixing post being connected to the battery devices of the two battery clusters on both sides along the first direction respectively.

[0030] In this embodiment, the first fixing post is connected to the battery devices of two battery clusters on both sides along the first direction. In other words, two adjacent battery clusters share the first fixing post. This will help to further reduce the number of fixing components that need to be set, thereby helping to further improve the energy density of the energy storage device.

[0031] In some embodiments, each battery cluster includes at least two battery device groups arranged along a second direction, and each battery device group includes a plurality of battery devices distributed along a gravity direction, wherein the first direction, the second direction, and the gravity direction are perpendicular to each other.

[0032] In this embodiment, each battery cluster is further configured to include two battery device groups distributed along the second direction, which will help to further increase the stacking density of the battery devices in the cavity.

[0033] In some embodiments, the energy storage device includes a plurality of control components disposed corresponding to the battery cluster, the control components being disposed on the bottom side of the corresponding battery cluster along the direction of gravity.

[0034] In this embodiment, by setting a control component, independent control of a single battery cluster can be achieved, which helps to improve the control and maintenance efficiency of the energy storage device. The control component is set on the bottom side of the corresponding battery cluster along the direction of gravity, which helps to improve space utilization.

[0035] In some embodiments, a gap is formed between adjacent battery devices along the direction of gravity; and / or, the support assembly includes an adapter, the adapter including a first adapter portion and a second adapter portion, the first adapter portion being fixed to the fixing post, the second adapter portion being located on the bottom side of the battery device along the direction of gravity, and the two ends of the battery device along the first direction being respectively supported by the two second adapter portions.

[0036] By creating a gap between adjacent battery units along the direction of gravity, the battery unit on the bottom side is relieved of its weight from supporting the top battery unit, which helps to further simplify the structure of the battery unit and reduce the cost of the energy storage device. The aforementioned adapter also increases the effective fixing area between the battery unit and the supporting components, thereby improving the installation stability of the battery unit and ultimately enhancing the reliability of the energy storage device.

[0037] In some embodiments, the support assembly includes a reinforcing beam connecting a plurality of the fixed columns; and / or, the support assembly includes a reinforcing rib connecting the fixed columns and the load-bearing member.

[0038] By incorporating reinforcing beams, multiple fixed columns can form a closed-loop stress distribution, enhancing their resistance to deformation and reducing the likelihood of deformation (e.g., bending) under the weight of the battery device and / or vibration (such as earthquakes or bumps during transport), thus improving the reliability of the energy storage device. Reinforcing ribs also increase the fixing area between the bottom of the fixed column and the load-bearing component, thereby improving the connection strength between the fixed column and the load-bearing component without significantly increasing the column's diameter, further enhancing reliability.

[0039] A second aspect of this application provides a container, the container including a detachably connected body and a carrier, the body opening downwards along the direction of gravity, the carrier closing the opening, the body and the carrier forming a receiving cavity, the receiving cavity being used to receive at least a battery device, and the carrier being used to support at least the battery device.

[0040] A third aspect of this application provides an energy storage system, the energy storage system including an energy storage converter and the energy storage device described in the first aspect of this application, wherein the energy storage converter is used to electrically connect a power generation device and the energy storage device.

[0041] A fourth aspect of the present application provides a charging network, including a charging pile and an energy storage device as described in the first aspect of the present application, or an energy storage system as described in the third aspect of the present application, wherein the energy storage device or the energy storage system is used to provide electrical energy to the charging pile.

[0042] The container, energy storage system, and charging network of the embodiments of this application have all the advantages of the energy storage device described in any of the above embodiments, and will not be repeated here. Attached Figure Description

[0053] This application proposes that in related technologies, the containers for energy storage devices are often designed to include an integrated steel structure welded frame, which results in a heavier overall weight, higher cost, and more difficult transportation of the energy storage device.

[0054] To address the aforementioned problems, an energy storage device according to an embodiment of this application is proposed. The energy storage device according to an embodiment of this application includes a container, a battery device, and a control device. The container includes a detachably connected body and a support member. The body opens downwards along the direction of gravity, and the support member closes the opening. The body and the support member enclose a receiving cavity. The battery device is disposed within the receiving cavity and supported by the support member. The control device is connected to the battery device to perform thermal management and / or electrical management of the battery device.

[0055] In the energy storage device of this embodiment, the container is configured as a split structure comprising a detachably connected body and a load-bearing component. The weight of the battery device is mainly supported by the load-bearing component, which reduces the structural strength requirements of the body, simplifies the body structure, and reduces its weight. Consequently, it helps to reduce the overall weight and cost of the energy storage device, and the transportation difficulty is also reduced accordingly due to the weight reduction. On the other hand, this configuration allows users to disassemble the energy storage device, transport it to the site, and then assemble it, further reducing transportation difficulty. Furthermore, in this embodiment, users are allowed to place the load-bearing component first, then assemble the battery device and other related structures onto the load-bearing component, and finally assemble the body onto the load-bearing component. Compared with the assembly method in related technologies that uses container doors for assembly, this assembly method provides a larger assembly operation space (reducing the obstruction caused by the body), facilitating the user's operation of large assembly mechanisms (such as forklifts, lifting structures, etc.), thereby helping to reduce the assembly difficulty of the energy storage device and improve assembly efficiency.

[0056] This application also provides a container, which is the container in the above-mentioned energy storage device. Specifically, the container includes a detachably connected body and a carrier. The body opens downwards along the direction of gravity, and the carrier closes the opening. The body and the carrier form a receiving cavity, which is used to accommodate at least the battery device, and the carrier is used to support at least the battery device.

[0057] This application also provides an energy storage system, including an energy storage converter and an energy storage device, wherein the energy storage converter is used to electrically connect the power generation device and the energy storage device.

[0058] This application also provides a charging network, including a charging pile and an energy storage device, wherein the energy storage device is used to provide electrical energy to the charging pile.

[0059] In some embodiments, the battery device may be a battery pack, which includes a battery housing and one or more individual battery cells housed within the battery housing.

[0060] As an example, a battery cell assembly can be a battery module, which can be housed in a battery housing by fixing the battery module in the battery housing.

[0061] As an example, battery cell assemblies can also be housed in a battery housing by directly fixing multiple battery cells to the battery housing.

[0062] In this embodiment of the application, the battery cell can be a secondary battery, which refers to a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged.

[0063] The battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and the embodiments of this application are not limited to this.

[0064] Below, some embodiments of this application will be described in detail with reference to the accompanying drawings.

[0065] Reference Figures 1 to 2 , Figure 1 This is a schematic diagram of the structure of a charging network 1000 provided in some embodiments of this disclosure. Figure 2 This is a schematic diagram of the structure of an energy storage system 2000 provided in some embodiments of this disclosure.

[0066] This disclosure provides a charging network 1000, which includes an energy storage device 100 and a charging pile 200. The charging pile 200 is used to charge electrical equipment, and the energy storage device 100 is electrically connected to the charging pile 200 to provide power to the charging pile 200.

[0067] It should be noted that the charging pile 200 and the battery cells in the energy storage device 100 are electrically connected via cables, and the battery cells can supply the charging pile 200 with their stored electrical energy. The charging pile 200 can be connected to electrical equipment, thereby replenishing the equipment's power. The application of the energy storage device 100 in this charging network 1000 can effectively improve the safety of the charging network 1000 and also help to enhance the flexibility of the charging network 1000 during deployment.

[0068] In a charging network 1000, there can be one charging pile 200, and the energy storage device 100 provides power to the one charging pile 200; there can also be multiple charging piles 200, and the energy storage device 100 provides power to multiple charging piles 200.

[0069] As an example, such as Figure 1 As shown, the charging network 1000 includes an energy storage device 100 and two charging piles 200, with the energy storage device 100 providing power to the two charging piles 200.

[0070] Figure 2 This is a schematic diagram of the structure of an energy storage system 2000 provided in some embodiments of this application. The energy storage system 2000 in this application includes an energy storage converter 300, which can be electrically connected to a power generation device 3000 to convert the electrical 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 energy storage converter 300. The energy storage converter 300 converts the electrical energy provided by the power generation device 3000 and then stores it in the energy storage device 100.

[0071] A power conversion device is used to connect the power generation device 3000 and the energy storage device 100. The power generation device 3000 generates electrical energy and stores the generated electrical energy in the energy storage device 100 via the power conversion device. The application of the energy storage device 100 in the energy storage system 2000 can effectively improve the operational safety of the energy storage system 2000. In specific implementations, the power generation equipment can be solar panels, hydroelectric power generation equipment, thermal power generation equipment, etc. This application does not limit the specific type of power generation equipment.

[0072] As an example, such as Figure 2 As shown, the energy storage system 2000 includes an energy storage device 100 and an energy storage converter 300. The two power generation devices 3000 respectively transmit the generated electrical energy to the energy storage converter 300, and the energy storage converter 300 introduces the electrical energy into the energy storage device 100 for storage.

[0073] Reference Figures 3-10The energy storage device 100 of this application embodiment includes a container 10, a battery device 21, and a control device 30. The container 10 includes a detachably connected box body 11 and a support member 12. The box body 11 opens downward along the direction of gravity, and the support member 12 closes the opening. The box body 11 and the support member 12 enclose a receiving cavity 10a. The battery device 21 is disposed in the receiving cavity 10a and supported by the support member 12. The control device 30 is connected to the battery device 21 to perform thermal management and / or electrical management of the battery device 21.

[0074] The container 10 is mainly used to provide storage space for the battery device 21 and to provide protection for the battery device 21.

[0075] Container 10 can be configured as a standard-sized container. Here, standard size refers to the dimensions of a standard container, such as 10 feet, 20 feet, 30 feet, 40 feet, or 45 feet, with corresponding standard dimensions for length, width, and height. Standard container 10 can be referenced in GB / T1413-2023 Series 1 Container 10 Classification, Dimensions, and Rated Mass.

[0076] A 10-foot dimension can include: a length dimension of 2991mm with a tolerance of 0mm-5mm; a width dimension of 2438mm with a tolerance of 0mm-5mm; and a height dimension of 2438mm or less with a tolerance of 0mm-5mm.

[0077] A 20-foot measurement may include: a length of 6058mm with a tolerance of 0mm-6mm; a width of 2438mm with a tolerance of 0mm-5mm; and a height of 2896mm, 2591mm, or no greater than 2438mm with a tolerance of 0mm-5mm.

[0078] A 30-foot measurement may include: a length dimension of 9125mm with a tolerance of 0mm-10mm; a width dimension of 2438mm with a tolerance of 0mm-5mm; and a height dimension of 2896mm, 2591mm, or no greater than 2438mm with a tolerance of 0mm-5mm.

[0079] A 40-foot dimension may include: a length dimension of 12192mm with a tolerance of 0mm-10mm; a width dimension of 2438mm with a tolerance of 0mm-5mm; and a height dimension of 2896mm, 2591mm, or no greater than 2438mm with a tolerance of 0mm-5mm.

[0080] A 45-foot unit can include: a length dimension of 13716mm with a tolerance of 0mm-10mm; a width dimension of 2438mm with a tolerance of 350mm-5mm; and a height dimension of 2591mm or 2896mm with a tolerance of 0mm-5mm.

[0081] In the embodiments of this application, for containers 10 of various sizes, dimensions within the range of ±1%, ±2%, ±3%, ±4%, and ±5% can be regarded as dimensions within the tolerance range.

[0082] Reference Figure 3 and Figure 4 In this embodiment, the container 10 includes a detachably connected container body 11 and a carrier 12.

[0083] Here, the specific implementation of the detachable connection between the housing 11 and the carrier 12 is not limited. For example, the housing 11 and the carrier 12 are connected by fasteners, including but not limited to bolts, buckles, etc. The housing 11 and the carrier 12 can be disassembled by removing the fasteners.

[0084] The box 11 opens downwards along the direction of gravity, which specifically refers to the direction of Earth's gravity, or in other words, the direction perpendicular to the Earth's center.

[0085] The phrase "the container 11 opens downwards along the direction of gravity" specifically means that the container 11 has an opening that faces the Earth's center along the direction of gravity. Taking a container 10 placed on a horizontal plane as an example, the bottom side of the container 11 forms an opening.

[0086] Taking the container 10 as a cuboid structure as an example, the container body 11 is a pentahedral structure with an opening facing downwards along the direction of gravity. In other words, the container body 11 is a structure with a top surface and four sides, and the four sides surround to form the aforementioned opening.

[0087] For example, the enclosure 11 includes multiple enclosure walls and adapters 182, with adjacent enclosure walls being fixedly connected by the adapters 182. In other words, the enclosure 11 is formed as a spliced ​​structure composed of multiple enclosure walls.

[0088] For example, the box 11 includes a box 11 frame and a box 11 panel, with the box 11 panel fixed to the box 11 frame. Here, the box 11 frame specifically refers to a frame structure composed of multiple beams joined together; in other words, the box 11 frame at least constitutes a portion of the side of the box 11. The box 11 panel is used to conceal the openwork portion of the box 11 frame; in other words, the box 11 panel at least constitutes a portion of the wall of the box 11.

[0089] The support member 12 closes the opening of the box 11. The specific structure of the support member 12 is not limited, as long as it can close the opening of the box 11.

[0090] Taking the container 10 as an example of a cuboid structure, in some embodiments, the support member 12 can be configured as a pallet structure, which can be understood as a roughly plate-shaped structure. In this case, the bottom surface of the container 11 can be supported by the top surface of the support member 12, or the outer peripheral surface of the support member 12 can be connected to the inner surface of the container 11, as long as the support member 12 can close the opening of the container 11. Of course, in some other embodiments, the support member 12 can also be configured as a structure with an upward opening along the direction of gravity, such as a pentahedral structure with an upward opening along the direction of gravity. In this case, the bottom end face of the container 11 can abut against the top end face of the support member 12, or one of the container 11 and the support member 12 can be nested inside the other, as long as the support member 12 can close the opening of the container 11.

[0091] In some embodiments, the load-bearing member 12 includes a frame body and a covering layer connected to the frame body. The frame body is formed as a welded integral structure. Exemplarily, the frame body is configured as a rectangular frame, which includes at least two longitudinal beams extending along a first direction and at least two transverse beams extending along a second direction. The two ends of each transverse beam are connected to the two longitudinal beams, and the two ends of each longitudinal beam are connected to the two transverse beams. Here, the first direction, the second direction, and the gravity direction are perpendicular to each other. In this way, the load-bearing capacity of the load-bearing member 12 is improved.

[0092] The housing 11 and the support member 12 together form a receiving cavity 10a, and the battery device 21 is disposed in the receiving cavity 10a and supported by the support member 12.

[0093] Here, "battery device 21 supported by support member 12" specifically means that at least a portion of the weight of battery device 21 is borne by support member 12. The weight of battery device 21 can be directly transferred to support member 12; for example, battery device 21 can be directly supported by support member 12 without passing through other load-bearing structures. Alternatively, the weight of battery device 21 can be indirectly transferred to support member 12; for example, battery device 21 can be indirectly supported by support member 12 via other load-bearing structures.

[0094] The number of battery devices 21 can be multiple, for example, refer to Figure 3 and Figure 4 Multiple battery devices 21 are arranged at least along the direction of gravity.

[0095] For example, refer to Figure 3 and Figure 4 The energy storage device 100 includes a plurality of battery clusters 20, each battery cluster 20 including a plurality of battery devices 21 arranged along the direction of gravity, the plurality of battery clusters 20 being distributed along a first direction perpendicular to the direction of gravity.

[0096] For example, the first direction is the length direction of container 10.

[0097] The control device 30 is used to connect to the battery device 21 to perform thermal management and / or electrical management of the battery device 21. Exemplarily, the control device 30 includes an electronic control device 31 and a thermal management device 32, the electronic control device 31 being connected to the battery device 21 to perform electrical management of the battery device 21, and the thermal management device 32 being connected to the battery device 21 to perform thermal management of the battery device 21.

[0098] Exemplary examples include, but are not limited to, electrical control cabinets, distribution cabinets, combiner cabinets, etc., as are well known to those skilled in the art. Thermal management devices 32 include, but are not limited to, liquid cooling units, air conditioning units, etc. The specific structural forms of the electrical control device 31 and the thermal management device 32, and their specific connection methods with the battery device 21, can be found in relevant technologies in the art, and will not be elaborated here.

[0099] It should be noted that the control device 30 is not limited to the above-mentioned electronic control device 31 and thermal management device 32. Those skilled in the art can set any suitable control device 30 according to actual usage requirements.

[0100] In the energy storage device 100 of this application embodiment, the container 10 is configured as a split structure including a detachably connected box body 11 and a support member 12. The weight of the battery device 21 is mainly supported by the support member 12, which reduces the structural strength requirements of the box body 11, helps to simplify the structure of the box body 11, reduces the weight of the box body 11, and thus helps to reduce the overall weight and cost of the energy storage device 100. The transportation difficulty is also reduced accordingly due to the reduction in weight. On the other hand, this configuration allows users to disassemble the energy storage device 100, transport it to the site, and then reassemble it, thereby further reducing the transportation difficulty. On the other hand, in this embodiment, the user is allowed to place the carrier 12 first when assembling the energy storage device 100, and then assemble the battery device 21 and other related structures onto the carrier 12, and finally assemble the housing 11 onto the carrier 12. Compared with the assembly method of assembling through the housing door in related technologies, this assembly method can provide a larger assembly operation space (reducing the obstruction caused by the housing 11), which makes it easier for the user to operate large assembly mechanisms (such as forklifts, lifting structures 10d, etc.) to perform assembly, thereby helping to reduce the assembly difficulty of the energy storage device 100 and improve the assembly efficiency.

[0101] In some embodiments, refer to Figure 3 and Figure 4 At least a portion of the control device 30 is supported by the support member 12.

[0102] Taking the control device 30, which includes an electronic control device 31 and a thermal management device 32, as an example, at least a portion of the electronic control device 31 may be supported on the support member 12, while at least a portion of the thermal management device 32 may be supported on other structures; or, at least a portion of the thermal management device 32 may be supported on the support member 12, while at least a portion of the electronic control device 31 may be supported on other structures; or, at least a portion of both the electronic control device 31 and the thermal management device 32 may be supported on the support member 12.

[0103] In the case where only a portion of the control device 30 is supported by the support member 12, for example, another portion of the control device 30 and the support member 12 are supported on the same working surface, such as the ground. Of course, the other portion of the control device 30 can also be supported by other suitable structures of the energy storage device 100; for example, a part of the control device 30 can be supported by another part of the control device 30.

[0104] In this embodiment, the carrier 12 further assumes the function of carrying the control device 30. This helps to improve the assembly stability of the control device 30 and the reliability of using the energy storage device 100. On the other hand, it also makes it possible for the control device 30, the battery device 21 and the carrier 12 to move together as a whole, reducing the difficulty of later maintenance.

[0105] In some embodiments, for example, the carrier 12 includes a first carrier portion and at least one second carrier portion. The first carrier portion is used to carry the battery device 21, and the second carrier portion is used to carry the control device 30. The first carrier portion and the second carrier portion are arranged in at least one direction perpendicular to the direction of gravity.

[0106] For example, the first support portion and the second support portion are arranged along a first direction and / or a second direction.

[0107] Here, the first direction, the second direction, and the direction of gravity are perpendicular to each other. Taking the container 10 as a cuboid structure as an example, the first direction is the length direction of the container 10, and the second direction is the width direction of the container 10.

[0108] In some embodiments, the first support portion and the second support portion are configured as an integral structure. Exemplarily, the first support portion and the second support portion are configured as an integral welded structure.

[0109] In this embodiment, by setting the first support part and the second support part as an integral structure, it helps to further reduce the assembly stability of the control device 30 and reduce the possibility of relative movement between the control device 30 and the battery device 21, thereby further improving the reliability of the energy storage device 100.

[0110] In some embodiments, the first support portion and the second support portion are configured to be detachably connected. Exemplarily, the first support portion and the second support portion are connected by fasteners (e.g., bolts, latches, etc.), so that the first support portion and the second support portion can be disassembled by removing the fasteners.

[0111] In this embodiment, by making the first support part and the second support part detachably connected, the first support part and the battery device 21 it carries can be removed separately, while the second support part and the control device 30 are left in place. In this process, it is only necessary to disconnect the connection between the first support part and the second support part and the connection between the battery device 21 and the control device 30. The connection between the control device 30 and the external structure can be partially or completely preserved. For example, the connection between the electronic control device 31 and the power conversion system (PCS), energy management system (EMS), and other structures can be preserved. Thus, the maintenance, expansion, reconfiguration, etc. of the energy storage device 100 can be achieved with lower operating costs and higher operating efficiency.

[0112] In some embodiments, as mentioned above, at least a portion of the control device 30 may be supported on the same working surface as the carrier 12, or a portion of the control device 30 may be supported on another portion of the control device 30.

[0113] In some embodiments, refer to Figure 3 At least a portion of the control device 30 is supported on the carrier 12 and located within the receiving cavity 10a.

[0114] For example, the container 10 may include a partition disposed in the receiving cavity 10a, which divides the receiving cavity 10a into a battery compartment and an electrical compartment. The battery device 21 is disposed in the battery compartment and the control device 30 is disposed in the electrical compartment. In this way, the battery device 21 and the control device 30 can be isolated to a certain extent, so as to better meet the environmental sealing requirements of the battery device 21 and the control device 30 respectively.

[0115] Of course, at least a portion of the control device 30 may also be located in the same compartment as the battery device 21 in the receiving cavity 10a.

[0116] Taking the control device 30, which includes an electronic control device 31 and a thermal management device 32, as an example, the electronic control device 31 may be supported on the support member 12 and located inside the receiving cavity 10a, while the thermal management device 32 may be located outside the receiving cavity 10a. Alternatively, the thermal management device 32 may be supported on the support member 12 and located inside the receiving cavity 10a, while the electronic control device 31 may be located outside the receiving cavity 10a. Or, both the electronic control device 31 and the thermal management device 32 may be supported on the support member 12 and located inside the receiving cavity 10a.

[0117] In this embodiment, by configuring at least a portion of the control device 30 to be supported on the support member 12 and located within the receiving cavity 10a, the housing 11 can provide certain limiting and / or protection for this portion of the control device 30. This helps to reduce the self-protection requirements of this portion of the control device 30 and / or simplify the relevant limiting structure, thereby helping to further simplify the structure of the energy storage device 100 and reduce costs.

[0118] In some embodiments, refer to Figure 4 At least a portion of the control device 30 is supported on the carrier 12 and located outside the receiving cavity 10a.

[0119] For example, the carrier 12 extends out of the housing 11 in at least one direction perpendicular to the direction of gravity, such as in a first direction and / or a second direction, so that at least a portion of the control device 30 is carried on the carrier 12 and located outside the receiving cavity 10a.

[0120] In this embodiment, by configuring at least a portion of the control device 30 to be supported on the carrier 12 and located outside the receiving cavity 10a, it helps to improve the convenience of user operation and / or maintenance of the control device 30 (which can be operated directly outside the container 11) and reduces the impact on the battery device 21 inside the receiving cavity 10a during maintenance. On the other hand, it helps to reduce the opening structure of the container 11 for accommodating the control device 30, thereby helping to reduce the sealing difficulty and cost of the container 10 and better meet the sealing requirements of the battery device 21.

[0121] It should be noted that, in some embodiments, at least a portion of the control device 30 may be supported on the same working surface as the support member 12 and located within the receiving cavity 10a. In some embodiments, at least a portion of the control device 30 may be supported on the same working surface as the support member 12 and located outside the receiving cavity 10a.

[0122] In some embodiments, refer to Figure 3 and Figure 4 The control device 30 includes an electronic control device 31 and a thermal management device 32. The electronic control device 31 is connected to the battery device 21 to perform electrical management of the battery device 21, and the thermal management device 32 is connected to the battery device 21 to perform thermal management of the battery device 21. Both the electronic control device 31 and the thermal management device 32 are supported on the support member 12.

[0123] The electronic control device 31 and the thermal management device 32 may both be located inside the receiving cavity 10a, or both may be located outside the receiving cavity 10a, or one may be located inside the receiving cavity 10a and the other may be located outside the receiving cavity 10a. There is no restriction on this.

[0124] In this embodiment, by setting both the electronic control device 31 and the thermal management device 32 to be supported on the support member 12, it helps to further improve the reliability of the energy storage device 100 and also helps to further reduce the difficulty of later maintenance.

[0125] In some embodiments, refer to Figure 3 and Figure 4 The energy storage device 100 includes a connecting line 40, which connects to the battery device 21 and the control device 30.

[0126] Here, the connecting pipeline 40 includes, but is not limited to, connecting wire harnesses (such as high-voltage wire harnesses, low-voltage wire harnesses, optical fibers, etc.) for connecting the electronic control device 31 and the battery device 21, and connecting pipelines (such as heat exchange medium pipelines) for connecting the battery device 21 and the thermal management device 32.

[0127] Taking the electronic control device 31 and / or thermal management device 32 as an example, which are supported by the carrier 12 and located outside the receiving cavity 10a, the carrier 12 may, exemplarily, have a wiring cavity through which the connecting line 40 extends into the receiving cavity 10a and connects to the battery device 21. Alternatively, the connecting line 40 may extend into the receiving cavity 10a and connect to the battery device 21 by means of a sealed through-wall structure passing through the wall of the housing 11. In comparison, wiring via the wiring cavity of the carrier 12 helps improve the sealing of the receiving cavity 10a and provides better protection for the connecting line 40.

[0128] Taking the example of the electronic control device 31 and / or thermal management device 32 being disposed on the carrier 12 and located within the receiving cavity 10a, the container 10 may include a partition that divides the space within the receiving cavity 10a into a battery compartment and an electrical compartment. The electronic control device 31 and / or thermal management device 32 are disposed in the electrical compartment, and the connecting pipeline 40 extends through the partition to the battery compartment and connects to the battery device 21 via a sealed through-wall structure.

[0129] In some embodiments, refer to Figure 3 and Figure 4 The control device 30 includes a fire control device 33, which is supported on the support member 12, or the fire control device 33 is supported on at least one of an electrical control device 31 and a thermal management device 32.

[0130] Here, the fire control device 33 is used for fire control. For example, the energy storage device 100 includes a fire sensor and a fire pipeline installed in the housing cavity 10a. The fire control device 33 is used to acquire the data collected by the fire sensor and control the fire pipeline to release the fire medium (e.g., inert gas, extinguishing agent, etc.).

[0131] For example, the fire control device 33 may be carried on the support member 12, or for example, the fire control device 33 may be carried on the electrical control device 31 and / or the thermal management device 32. This embodiment does not limit this.

[0132] In this embodiment, by mounting the fire control device 33 on the support member 12, the assembly difficulty is reduced. By setting the fire control device 33 to be mounted on the electrical control device 31 and / or the thermal management device 32, space reuse in the direction of gravity is achieved, thereby improving space utilization.

[0133] In some embodiments, refer to Figure 5 The container 11 has at least one first door opening 11a corresponding to the battery device 21, and the container 10 includes a first door 13 disposed in the first door opening 11a.

[0134] Here, the first doorway 11a specifically refers to the opening structure formed in the housing 11 that communicates with the receiving cavity 10a. The first doorway 11a being correspondingly arranged with the battery device 21 specifically means that the first doorway 11a is connected to the space where the battery device 21 is located (e.g., the battery compartment). For example, in the same projection plane perpendicular to the opening direction of the first doorway 11a, the projection of the battery device 21 and the projection of the first doorway 11a at least partially overlap.

[0135] The number of first openings 11a can be multiple. For example, the battery device 21 includes multiple battery clusters 20 distributed along a first direction, and the multiple first openings 11a are distributed along the first direction. Each battery cluster 20 is provided with at least one first opening 11a.

[0136] The first door 13 is configured to open or close the first door opening 11a. Exemplarily, the first door 13 is configured to be sealed to the housing 11 (e.g., sealed to the housing 11 via a sealing strip) to close the first door opening 11a.

[0137] In this embodiment, by providing a first doorway 11a, users can open the first door 13 and perform simple maintenance on the battery device 21 through the first doorway 11a during actual use, thus reducing the maintenance difficulty and cost of the energy storage device 100.

[0138] Of course, in some other embodiments, the housing 11 may not be provided with the first door opening 11a and the first door 13, and the housing 11 can be disassembled from the support member 12 when the battery device 21 needs to be maintained.

[0139] In some embodiments, refer to Figure 6At least a portion of the control device 30 is located within the receiving cavity 10a, the container 11 has at least one second door opening 11b corresponding to the control device 30, and the container 10 includes a second door 14 disposed in the second door opening 11b.

[0140] Similar to the first doorway 11a, the second doorway 11b specifically refers to an opening structure formed in the housing 11 that communicates with the receiving cavity 10a. The second doorway 11b being correspondingly positioned with the control device 30 specifically means that the second doorway 11b communicates with the space where the control device 30 is located (e.g., the electrical compartment). For example, in the same projection plane perpendicular to the opening direction of the second doorway 11b, the projection of the control device 30 at least partially overlaps with the projection of the second doorway 11b.

[0141] The second door 14 is configured to open or close the second door opening 11b. Exemplarily, the second door 14 is configured to be sealed to the housing 11 (e.g., sealed to the housing 11 via a sealing strip) to close the second door opening 11b.

[0142] In this embodiment, by providing a second doorway 11b, the user can open the second door 14 to perform maintenance on the control device 30 during actual use, and the container 10 can be kept sealed through the second door 14 during normal use.

[0143] Of course, in some other embodiments, the container 11 may not be provided with the second door 14, and the control device 30 may be exposed on the outer surface of the container 10 through the second door opening 11b. In this case, the control device 30 may be sealed to the container 10 to maintain the sealing of the container 10.

[0144] In some embodiments, refer to Figure 5 and Figure 6 The container 10 includes a hinge 15 that hinges the first door 13 and / or the second door 14 to the container body 11, thereby enabling the first door 13 and / or the second door 14 to rotate relative to the container body 11 to open or close the first door opening 11a and / or the second door opening 11b.

[0145] In some embodiments, further, refer to Figure 5 and Figure 6 The container 10 includes a locking member 16 disposed on the first door 13 and / or the second door 14. The locking member 16 is configured to lock or unlock the first door 13 and / or the second door 14 to the container body 11, thereby enabling the first door 13 and / or the second door 14 to be kept in a closed state of the first door opening 11a and / or the second door opening 11b.

[0146] In some embodiments, refer to Figure 6The control device 30 includes an electronic control device 31 and a thermal management device 32 disposed in the receiving cavity 10a. The container 11 has two second door openings 11b, which correspond to the electronic control device 31 and the thermal management device 32, respectively. The second door opening 11b corresponding to the electronic control device 31 is provided with a second door body 14, while the second door opening 11b corresponding to the thermal management device 32 is not provided with a second door body 14. The thermal management device 32 is exposed on the outer surface of the container 10 through the second door opening 11b, thus meeting the heat dissipation requirements of the thermal management device 32.

[0147] In some embodiments, refer to Figure 8 The container 10 includes an insulation structure 10b, which is disposed in at least one of the container body 11 and the load-bearing member 12.

[0148] Here, the specific structural form of the insulation structure 10b is not limited. For example, the insulation structure 10b includes insulation filler, which includes, but is not limited to, wood materials (e.g., wood chips, wood strips, etc.), foam plastics (e.g., polyvinyl chloride foam), rock wool, glass fiber, ceramic fiber, and aerogel insulation materials. For another example, the insulation structure 10b includes an insulation board.

[0149] Taking the insulation structure 10b disposed in the housing 11 as an example. In an embodiment where the insulation structure 10b includes insulation filler, exemplarily, refer to... Figure 8 The housing 11 includes multiple housing walls, each housing wall comprising a housing wall beam 111, an inner covering layer 112 disposed on the housing wall beam 111 facing the receiving cavity 10a, and an outer covering layer 113 disposed on the housing wall beam 111 away from the receiving cavity 10a. Thermal insulation filler is disposed between the inner covering layer 112 and the outer covering layer 113. In an embodiment where the thermal insulation structure 10b includes an insulation board, exemplarily, the housing 11 includes a housing 11 frame and a housing 11 plate disposed on the housing 11 frame, the housing 11 plate including an insulation board.

[0150] In this embodiment, by setting the thermal insulation structure 10b, the thermal insulation performance of the container 10 is improved. This helps to reduce the requirements for the thermal insulation performance of the battery device 21 itself, which simplifies the structure of the battery device 21, reduces the cost of the energy storage device 100 and increases the energy density.

[0151] In some embodiments, refer to Figure 8 The container 10 includes a sealing structure 10c, which is disposed between the container body 11 and the load-bearing member 12.

[0152] Here, the specific structural form of the sealing structure 10c is not limited. For example, the sealing gasket is set as a flexible structure, such as a rubber body, silicone body, sponge body, etc., so as to effectively fill the gap between the box 11 and the carrier 12 and achieve a sealed connection between the box 11 and the carrier 12.

[0153] For example, the bottom surface of the housing 11 along the direction of gravity is supported by the top surface of the support member 12 along the direction of gravity, and the sealing structure 10c is disposed between the housing 11 and the support member 12 along the direction of gravity.

[0154] For example, in the orthographic projection of a plane perpendicular to the direction of gravity, the sealing structure 10c extends circumferentially along the container 10 to form a ring-shaped closed structure. In other words, the sealing gasket is configured to completely cover the connection between the container body 11 and the carrier 12, thereby improving the sealing connection performance between the container body 11 and the carrier 12.

[0155] In this embodiment, by setting the sealing structure 10c, the sealing performance of the container 10 is improved. This helps to reduce the requirements for the sealing performance of the battery device 21 itself, which simplifies the structure of the battery device 21, reduces the cost of the energy storage device 100 and increases the energy density.

[0156] In some embodiments, container 10 is configured to meet at least the IP67 standard for waterproofing and dustproofing.

[0157] Here, IP stands for Ingress Protection Rating (or International Protection code), which defines an interface's ability to protect against liquid and solid particles. The first digit after IP indicates the solid protection rating, ranging from 0 to 6, representing protection against everything from large foreign objects to dust; the second digit indicates the liquid protection rating, ranging from 0 to 8, representing protection against everything from vertical water droplets to pressure at the bottom of the water. The higher these two digits are, the stronger the protection.

[0158] By setting the container 10 to meet at least the IP67 standard for waterproof and dustproof requirements, the requirements for the sealing performance of the battery device 21 itself can be further reduced, and even the battery cells of the battery device 21 can be directly exposed in the housing cavity 10a. In this way, the structure of the battery device 21 can be further simplified, the cost of the energy storage device 100 can be reduced, and the energy density can be increased.

[0159] In some embodiments, refer to Figure 8 The container 10 includes bolted connectors that securely connect the container body 11 and the load-bearing member 12.

[0160] For example, the threaded connection includes a bolt.

[0161] In this embodiment, the housing 11 and the carrier 12 are fixedly connected by screws, which helps to further improve assembly efficiency and reduce assembly costs. Furthermore, fixing the housing 11 and the carrier 12 by screws also improves the ease of disassembling the housing 11, facilitating maintenance and replacement of the housing 11 and other structures within the receiving cavity 10a.

[0162] In the embodiment of the container 10 that includes a sealing gasket, for example, the screws pass through the container body 11, the sealing gasket and the carrier 12 in sequence along the direction of gravity, thereby achieving a fixed connection between the container body 11, the sealing gasket and the carrier 12.

[0163] It should be noted that the fixed connection between the housing 11 and the bearing 12 is not limited to this method. For example, it can also be achieved by snap-fit, tenon and mortise connection, etc.

[0164] In some embodiments, refer to Figure 3 and Figure 4 The container 10 includes a lifting structure 10d, which is disposed in at least one of the container body 11 and the load-bearing member 12.

[0165] For example, the lifting structure 10d includes a lifting hole for threading a lifting rope.

[0166] Taking the lifting structure 10d as a load-bearing component 12 as an example, the load-bearing component 12 is a rectangular structure, and the four corners of the load-bearing component 12 are provided with support feet, and the support feet have lifting holes. Taking the lifting structure 10d as a box body 11 as an example, the box body 11 is a cuboid structure, and the four apex corners of the box body 11 are provided with lifting ears, and the lifting ears have lifting holes.

[0167] In this embodiment, by providing a hoisting structure 10d on the container 11 and / or the carrier 12, the container 11 and / or the carrier 12 can be installed and disassembled by hoisting. Furthermore, the container 10 can be moved as a whole by hoisting (that is, the container 11 can be moved as a whole while it is installed on the carrier 12), thereby further reducing the transportation difficulty, assembly difficulty, and maintenance difficulty of the energy storage device 100.

[0168] In some embodiments, the container 10 includes a liquid guide 17 disposed on the carrier 12, one end of the liquid guide 17 opening into the receiving cavity 10a, and the other end opening onto the surface of the carrier 12 opposite to the receiving cavity 10a.

[0169] Here, the specific structural form of the liquid guiding member 17 is not limited. For example, the liquid guiding member 17 includes a liquid guiding pipe, one end of which opens into the receiving cavity 10a, and the other end opens into the surface of the carrier 12 away from the receiving cavity 10a, for example, opening into the bottom surface of the receiving cavity 10a along the direction of gravity and / or the surface in the direction perpendicular to the direction of gravity.

[0170] In this embodiment, by providing a liquid guiding component 17 on the support component 12, the condensate in the receiving cavity 10a can be discharged to the outside of the receiving cavity 10a by means of gravity, thereby improving the reliability of the energy storage device 100.

[0171] In some embodiments, refer to Figure 9 The battery device 21 includes a battery housing 211 and a battery cell assembly 212. The battery housing 211 has a mounting cavity 211a, and the battery cell assembly 212 is disposed in the mounting cavity 211a.

[0172] Here, the specific structural form of the battery box 211 is not limited. For example, the battery box 211 includes a box body and a cover. The box body has an opening, and the cover is placed over the opening of the box body. The box body and the cover form an installation cavity 211a, and the battery cell assembly 212 is disposed in the installation cavity 211a.

[0173] In this embodiment, by configuring the battery device 21 to include a battery housing 211 and placing the battery cell assembly 212 in the mounting cavity 211a of the battery housing 211, the protection function of the battery cell assembly 212 is improved, thereby improving the reliability of the energy storage device 100.

[0174] In some embodiments, refer to Figure 10 The battery device 21 includes a support mechanism 213 and a battery cell assembly 212, with the battery cell assembly 212 supported by the support mechanism 213 and exposed in the receiving cavity 10a.

[0175] Here, the specific structural form of the supporting mechanism 213 is not limited, as long as it can support the battery cell assembly 212.

[0176] For example, the support mechanism 213 is configured as a plate-like structure, and for example, the support mechanism 213 is configured in a structure with the opening facing upward along the direction of gravity.

[0177] For example, the support mechanism 213 includes a heat exchange plate with a medium flow channel that is connected to the thermal management device 32 to conduct heat exchange medium for exchanging heat with the battery cell assembly 212. This allows the support mechanism 213 to exchange heat with the battery cell assembly 212 while supporting it.

[0178] Understandably, compared with the battery housing 211, the supporting structure 213 has a simpler structure, lower cost, smaller footprint, and simpler assembly. This helps to reduce the cost and assembly difficulty of the energy storage device 100 and improve the energy density of the energy storage device 100.

[0179] Furthermore, it is understood that in this embodiment, the environmental requirements for the use of the battery cell assembly 212 can be met by improving the sealing performance and thermal insulation performance of the container 10. For example, this simplifies the structure of the energy storage device 100, increases the energy density of the energy storage device 100, and also ensures the reliability of the energy storage device 100. For example, in this embodiment, the container 10 is configured to meet at least the IP67 standard for waterproof and dustproof requirements.

[0180] In some embodiments, refer to Figure 3 and Figure 4 The container 10 includes a support assembly 18, which is fixed to the support member 12 and extends along the direction of gravity, and a plurality of battery devices 21 are distributed along the direction of gravity on the support assembly 18.

[0181] The specific structural form of the support component 18 is not limited, as long as it can support a plurality of battery devices 21 distributed along the direction of gravity. For example, the support component 18 has a plurality of mounting positions distributed along the direction of gravity, and each mounting position is provided with at least one battery device 21.

[0182] In this embodiment, multiple battery devices 21 are distributed along the direction of gravity on the supporting component 18. This helps to reduce the interaction force between two adjacent battery devices 21 along the direction of gravity and helps to improve the stability of the stacking of battery devices 21 along the direction of gravity, thereby helping to improve the reliability of the energy storage device 100.

[0183] In some embodiments, the support component 18 is detachably connected to the carrier 12.

[0184] The specific implementation of the detachable connection between the support component 18 and the carrier component 12 is not limited. For example, the support component 18 and the carrier component 12 are connected by fasteners (e.g., bolts), so that the support component 18 can be installed and removed by installing and removing the fasteners. For another example, the support component 18 and the carrier component 12 can be detachably connected by means such as snap-fit ​​or interference fit.

[0185] In this embodiment, by setting the support component 18 to be detachably connected to the carrier component 12, on the one hand, it helps to further reduce the difficulty of transportation. For example, the box 11, carrier component 12, support component 18 and battery device 21 can be transported to the site separately and then assembled. On the other hand, this setting allows users to detach one support component 18 from the carrier component 12 and install another support component 18 onto the carrier component 12. In this way, the arrangement and number of battery devices 21 in the energy storage device 100 can be changed by changing the support component 18, providing more possibilities for the expansion and structural changes of the energy storage device 100.

[0186] In some embodiments, the support component 18 includes a plurality of fixed posts 181 extending along the direction of gravity, the plurality of fixed posts 181 being distributed at least along a first direction, and both ends of the battery device 21 along the first direction being connected to the fixed posts 181, the first direction being perpendicular to the direction of gravity.

[0187] Here, the specific implementation of the connection between the battery device 21 and the fixing post 181 is not limited. The battery device 21 and the fixing post 181 can be directly connected or indirectly connected by means of an intermediate structure. This embodiment does not impose any restrictions on this.

[0188] For example, the battery device 21 has a cuboid structure. The width direction of the battery device 21 is parallel to the first direction, and the length direction of the battery device 21 is parallel to the second direction. Each battery device 21 has two fixing posts 181 on each side along the first direction, and the two fixing posts 181 on the same side are distributed along the second direction. In this way, all four corner areas of the battery device 21 are connected to the fixing posts 181, improving the support reliability of the battery device 21.

[0189] Of course, each battery device 21 may also have a fixing post 181 on each side along the first direction. Alternatively, more fixing posts 181 may be provided on each side of each battery device 21 along the first direction, which can be determined by those skilled in the art according to actual fixing requirements.

[0190] In this embodiment, the support component 18 of this structural form can provide reliable support for the battery device 21 while reducing the space occupied in the housing cavity 10a, thereby helping to improve the energy density of the energy storage device 100.

[0191] In some embodiments, refer to Figure 3 and Figure 4The energy storage device 100 includes multiple battery clusters 20, each battery cluster 20 including multiple battery devices 21 arranged along the direction of gravity, the multiple battery clusters 20 are arranged along a first direction, the first direction being perpendicular to the direction of gravity, and the fixing post 181 includes a first fixing post 181a disposed between two adjacent battery clusters 20, the first fixing post 181a being connected to the battery devices 21 of the two battery clusters 20 on both sides along the first direction respectively.

[0192] In this embodiment, the first fixing post 181a is connected to the battery device 21 of the two battery clusters 20 on both sides along the first direction. In other words, the two adjacent battery clusters 20 share the first fixing post 181a. This will help to further reduce the number of fixing parts that need to be set, thereby helping to further improve the energy density of the energy storage device 100.

[0193] In some embodiments, refer to Figure 7 Each battery cluster 20 includes at least two battery device groups 20a arranged along a second direction, and each battery device group 20a includes a plurality of battery devices 21 distributed along the gravity direction, wherein the first direction, the second direction and the gravity direction are perpendicular to each other.

[0194] For example, refer to Figure 7 The fixing post 181 includes a second fixing post 181b disposed along a second direction between two adjacent battery packs 20a. The second fixing post 181b is connected to the battery packs 21 of the two battery packs 20a on both sides along the second direction. In this way, the second fixing post 181b is fixed between the two adjacent battery packs 20a, further reducing the number of fixing components required, thereby helping to further improve the energy density of the energy storage device 100.

[0195] In this embodiment, each battery cluster 20 is further configured to include two battery device groups 20a distributed along the second direction, which will help to further increase the stacking density of the battery devices 21 in the receiving cavity 10a.

[0196] In some embodiments, refer to Figure 7 The energy storage device 100 includes a plurality of control components 50 corresponding to the battery cluster 20. The control components 50 are disposed on the bottom side of the corresponding battery cluster 20 along the direction of gravity. The control components 50 are supported by the support member 12, or the control components 50 are fixed to the fixing column 181.

[0197] It should be noted that the main difference between the control component 50 and the aforementioned electronic control device 31 is that the control component 50 is used for electrical management of the battery devices 21 within a single battery cluster 20, while the electronic control device 31 is used for electrical management of multiple battery clusters 20. In other words, the electronic control device 31 is used for electrical management at the level of the energy storage device 100, while the control component 50 is used for electrical management at the level of the battery devices 21.

[0198] For example, the control component 50 is configured in a one-to-one correspondence with the battery cluster 20, that is, each battery cluster 20 is configured with one control component 50. Of course, one control component 50 can also correspond to multiple battery clusters 20, or multiple control components 50 can also correspond to one battery cluster 20.

[0199] For example, the control component 50 includes a control component 50 body and a controller disposed within the control component 50 body. The controller is electrically connected to the battery cell assembly 212 and includes at least one of an on / off unit and a battery management unit.

[0200] For example, the on / off unit is used to perform high-voltage control on the battery device 21 within the same battery cluster 20, and the battery management unit is used to perform low-voltage control on the battery device 21 within the same battery cluster 20.

[0201] For example, the battery management unit includes a sampling unit and a main control unit. The sampling unit is electrically connected to the battery device 21 to collect electrical signals, and the main control unit is electrically connected to the sampling unit and the on / off unit.

[0202] Here, the sampling unit CSC is used to collect temperature, current, voltage signals, etc. of the battery device 21, and the number of main control units SBMU is usually one, which is used to control the charging and discharging state of each battery device 21.

[0203] For example, a CSC includes a microcontroller unit (MCU) and at least one AFE chip, namely: AFE chip 1, ..., AFE chip m-1 and AFE chip m, each AFE chip being electrically connected to a battery device 21. The AFE chip can also be used to perform equalization functions. Alternatively, a CSC may also include one AFE chip electrically connected to all battery devices 21 in the battery cluster 20, used to collect data such as voltage, current, and temperature of all battery devices 21. The term AFE chip can also be replaced with other terms, such as acquisition chip. Furthermore, there is a communication connection between the MCU and the m AFE chips to control the m AFE chips. The SBMU can provide power to the MCU. Additionally, the MCU can be used for data processing, interface management, and communication. The SBMU and CSC can communicate via a dual cluster controller area network (CCAN) bus. Specifically, two CCAN buses, CCAN-H and CCAN-L, are deployed between the SBMU and CSC. CCAN-H is used to transmit high-voltage signals, and CCAN-L is used to transmit low-voltage signals. The SBMU can supply power to the CSC via two wires.

[0204] For example, in this embodiment, the housing 11 may include a first doorway 11a and a first door 13 disposed in the first doorway 11a, through which the user can operate the control component 50.

[0205] For example, the control component 50 can be placed directly on the carrier 12, or for example, the control component 50 can be connected to the fixed column 181. This embodiment does not limit this.

[0206] In this embodiment, by setting the control component 50, independent control of a single battery cluster 20 can be achieved, which helps to improve the control and maintenance efficiency of the energy storage device 100. The control component 50 is set on the bottom side of the corresponding battery cluster 20 along the direction of gravity, which helps to improve space utilization.

[0207] Of course, in some other embodiments, the control component 50 may also be directly mounted on the support member 12. In some other embodiments, the control component 50 may be mounted on the support member 12 and located outside the receiving cavity 10a, thus facilitating user operation of the control component 50. In some other embodiments, the energy storage device 100 may not include the aforementioned control component 50, and the functions of the control component 50 may be integrated into the electronic control device 31.

[0208] In some embodiments, a gap is formed between adjacent battery devices 21 along the direction of gravity.

[0209] This eliminates the need for the bottom battery device 21 to bear the weight of the top battery device 21, which helps to further simplify the structure of the battery device 21 and reduce the cost of the energy storage device 100.

[0210] Of course, in some other embodiments, adjacent battery devices 21 can also abut against each other along the direction of gravity, thereby improving space utilization.

[0211] In some embodiments, refer to Figure 11 The supporting component 18 includes a connector 182, which includes a first connector 1821 and a second connector 1822. The first connector 1821 is fixed to the fixing post 181, and the second connector 1822 is located on the bottom side of the battery device 21 along the direction of gravity. The two ends of the battery device 21 along the first direction are respectively supported by the two second connectors 1822.

[0212] For example, the first adapter 1821 and the second adapter 1822 are configured as sheet-like structures, the first adapter 1821 is fixed to one side surface of the fixing post 181 along the first direction, and the second adapter 1822 is disposed on the bottom surface of the battery device 21.

[0213] For example, the adapters 182 at both ends of the same battery device 21 along the first direction are respectively the first adapter and the second adapter, and the second adapter portions 1822 of the first adapter and the second adapter are spaced apart along the first direction. In this way, the volume of the adapter 182 is reduced, and the weight and cost are reduced.

[0214] In this embodiment, by setting the adapter 182, the effective fixing area between the battery device 21 and the support component 18 is increased, thereby improving the installation stability of the battery device 21 and the reliability of the energy storage device 100.

[0215] Of course, in some other embodiments, the support component 18 may not include the adapter 182 described above, and the battery device 21 may be directly fixed to the fixing post 181, for example, by directly bolting it to the fixing post 181.

[0216] In some embodiments, refer to Figure 3 and Figure 4The supporting component 18 includes a reinforcing beam 183, which connects to multiple fixed posts 181. Thus, the multiple fixed posts 181, together with the reinforcing beam 183, form a closed-loop stress distribution, improving the deformation resistance of the fixed posts 181 and reducing the likelihood of deformation (e.g., bending) of the fixed posts 181 under the gravity of the battery device 21 and / or under vibration (e.g., during an earthquake, or during transport), thereby improving the reliability of the energy storage device 100.

[0217] For example, the reinforcing beam 183 is positioned on the top side of the battery cluster 20 along the direction of gravity and connects to the top of a plurality of fixed columns 181, thereby reducing the possibility of interference between the reinforcing beam 183 and the battery device 21.

[0218] For example, there are multiple reinforcing beams 183, including a first reinforcing beam and a second reinforcing beam. The first reinforcing beam and the second reinforcing beam are connected, and the extension directions of the first reinforcing beam and the second reinforcing beam intersect (that is, the first reinforcing beam and the second reinforcing beam are arranged crosswise). This helps to further optimize the stress distribution, thereby further reducing the possibility of deformation of the fixed column 181.

[0219] In some embodiments, refer to Figure 11 The support assembly 18 includes a reinforcing rib 184 that connects the fixing post 181 and the load-bearing member 12. This helps to increase the fixing area between the bottom end of the fixing post 181 and the load-bearing member 12, thereby helping to increase the connection strength between the fixing post 181 and the load-bearing member 12 without increasing the diameter of the fixing post 181 as much as possible, thus improving the reliability of use.

[0220] For example, the reinforcing rib 184 includes a first reinforcing rib and a plurality of second reinforcing ribs. The first reinforcing rib is configured as an annular structure extending circumferentially along the fixed column 181, and the bottom surface of the first reinforcing rib is connected to the bearing member 12. The second reinforcing rib is configured as a triangular sheet structure, with one side of the second reinforcing rib connected to the fixed column 181 and the other side connected to the top surface of the first reinforcing rib. The plurality of second reinforcing ribs are distributed circumferentially along the fixed column 181.

[0221] Embodiments of this application also provide a container 10, referring to... Figure 3 and Figure 4 The container 10 includes a detachably connected body 11 and a support member 12. The body 11 opens downward along the direction of gravity, and the support member 12 closes the opening. The body 11 and the support member 12 enclose a receiving cavity 10a, which is used to receive at least the battery device 21, and the support member 12 is used to support at least the battery device 21.

[0222] The specific technical details of container 10 can be found in the relevant sections above, and will not be repeated here.

[0223] The energy storage device 100 of one or more embodiments described above will be described in more detail below with reference to a specific embodiment.

[0224] Reference Figures 3-11 The energy storage device 100 includes a container 10, a support component 18, a thermal management device 32, an electrical control device 31, connecting pipelines 40, and a battery device 21, etc.

[0225] The container 10 includes a body 11 and a support member 12. The body 11 is a pentahedral structure with an opening facing downwards along the direction of gravity. The body 11 and the support member 12 are detachably connected, and the support member 12 closes the opening of the body 11. During installation, the body 11 is hoisted onto the support member 12 as a whole pentahedral structure, covering all battery devices 21 within the receiving cavity 10a, and simultaneously locking it to the support member 12. A sealing strip is installed at the locking interface to achieve overall sealing after installation.

[0226] The load-bearing component 12 is designed as a welded integral structure made of steel plates or rectangular profiles connected by welding. It bears the weight of all materials installed on the upper layer and meets the stress requirements under complex working conditions such as transportation fixation, hoisting fixation, and transportation bumps.

[0227] The container 11 has a door opening (first door opening 11a and / or second door opening 11b) and a maintenance door (first door body 13 and / or second door body 14) located in the door opening. The maintenance door is connected to the container 11 by a hinge 15 and a locking member 16, and has a sealing interface to ensure the overall sealing effect of the container 10.

[0228] The enclosure 11 has a thermal insulation structure 10b. For example, the enclosure 11 is made of composite materials such as lightweight rock wool board. While meeting the functions of thermal insulation, flame retardancy and sealing, it provides a good working environment for the internal equipment such as the battery device 21 in the cavity 10a. It is also lightweight, low cost, and easy to replace. At the same time, it does not affect the maintenance of components. With the enclosure 11 installed on the support 12, the maintenance door can be opened to replace all internal components, including the battery device 21.

[0229] Furthermore, the battery unit 21 is mounted on the support assembly 18, which includes fixing posts 181 and adapters 182. The fixing posts 181 are mainly distributed on both sides of each row of battery units 21 along the first direction. The fixing posts 181 are composed of rectangular profiles, and the bottom of each fixing post 181 is bolted to the support member 12. The fixing posts 181 are bolted to the support member 12. The tops of multiple fixing posts 181 are interconnected by reinforcing beams 183 to ensure overall rigidity and reduce the possibility of swaying or failure during transportation and earthquake conditions. Reinforcing ribs 184 are provided at the bottom of the fixing posts 181 to increase the load-bearing area at the base of the fixing posts 181 and prevent localized stress concentration.

[0230] The thermal management device 32 is used to ensure that the battery device 21 is always maintained within a good temperature range during use, so as to avoid the overall system's usable power being affected by the ambient temperature. The electronic control device 31 integrates the functions of power distribution and overall control. It mainly controls the on / off switching and detection of the high-voltage and low-voltage circuits of the system, and transmits data such as system operating temperature, voltage, and faults to the external EMS, so that customers can monitor the operating status of the energy storage device 100 in real time.

[0231] The top side of the electrical control device 31 is equipped with a fire control device 33, which is mainly used to realize the control and monitoring functions of the fire protection system, ensuring that the entire fire protection system is always under control during operation, and transmitting the operation data to the external EMS for easy monitoring by the client. The fire control device 33 is equipped with a backup power supply so that the fire control device 33 can operate normally after the auxiliary power supply fails.

[0232] The electronic control device 31 and / or the thermal management device 32 can be disposed inside the receiving cavity 10a or installed outside the receiving cavity 10a as replaceable accessories.

[0233] The battery device 21 can be a complete unit with a self-sealing interface including the top cover, or it can be a minimal structure without the top cover, only including the necessary water cooling plate, lower casing, flame retardant protection measures, etc.

[0234] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, and improvements made within the spirit and scope of this application are included within the scope of protection of this application.
