Technical Field

[0002] The present disclosure relates to the field of battery technology, and in particular to an energy storage device, an energy storage system, and a charging network. Background Art

[0003] 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.

[0004] 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.

[0005] Summary of the Invention

[0006] In view of this, embodiments of the present disclosure aim to provide an energy storage device, an energy storage system, and a charging network that can reduce the cost of using the energy storage device.

[0007] To achieve the above objectives, a first aspect of an embodiment of the present disclosure provides an energy storage device, comprising:

[0008] A plurality of bins, wherein the bins are arranged along a first direction of the bins;

[0009] A plurality of energy units, wherein the plurality of energy units are accommodated in at least one of the storage bodies;

[0010] a control module, the control module being used to electrically control the plurality of energy units;

[0011] Among them, the size of at least one of the multiple warehouse bodies along the first direction is smaller than the size of a standard container along the first direction, the sum of the sizes of the multiple warehouse bodies along the first direction is greater than the sum of the sizes of one or more standard containers along the first direction, and the first direction is the length direction, width direction or height direction of the warehouse body.

[0012] The energy storage device provided by the embodiment of the present disclosure can reduce the total weight of the warehouse body and the components therein by reducing the size of the warehouse body, which is beneficial to improving the problem of overweight transportation, reducing the transportation cost of the energy storage device, and thus reducing the use cost of the energy storage device. The sum of the dimensions of the multiple warehouse bodies along the first direction is set to be greater than the sum of the dimensions of one or more standard containers along the first direction. That is to say, on the one hand, the sum of the dimensions of the multiple warehouse bodies along the first direction is set to be greater than the sum of the dimensions of one or more standard containers along the first direction, which means that the dimension of at least one warehouse body along the first direction is made as large as possible, and the power of the energy storage device can be increased as much as possible while meeting the transportation weight. On the other hand, it is beneficial to increase the volume and power of the energy storage device, further reducing the use cost of the energy storage device.

[0013] In some embodiments, the size of at least one of the plurality of warehouses along the first direction is greater than or equal to one third of the size of the standard container along the first direction, and is smaller than the size of one standard container along the first direction.

[0014] The size of the warehouse body cannot be infinitely small. When the size of the warehouse body along the first direction is greater than or equal to one-third of the size of a standard container along the first direction, the energy storage device has high manufacturability, high volume energy density, and is more convenient to transport and install.

[0015] In some embodiments, a size of at least one of the plurality of warehouse bodies along the first direction is greater than or equal to half a size of the standard container along the first direction, and is smaller than a size of one standard container along the first direction.

[0016] When the size of the silo along the first direction is greater than or equal to half the size of a standard container along the first direction, the energy storage device has high manufacturability, high volumetric energy density, and is more convenient to transport and install. For example, when the energy storage device includes two stacked silos, multiple energy units are placed in each silo, and the size of each silo along the first direction is greater than or equal to half the size of a standard container along the first direction, and is smaller than the size of a standard container along the first direction. When the two silos are stacked, they are taller than a standard container, but the total weight of each silo containing components such as energy units is lower. With this arrangement, each silo containing components such as energy units of the energy storage device can be transported separately, and after being stacked at the place of use, the energy storage device has a higher power consumption.

[0017] In some embodiments, the size of at least one of the plurality of warehouses along the first direction is greater than or equal to one-third of the size of the standard container along the first direction, and less than one-half of the size of the standard container along the first direction.

[0018] When the size of the silo along the first direction is greater than or equal to one-third the size of a standard container along the first direction, the energy storage device has high manufacturability, high volumetric energy density, and is more convenient to transport and install. For example, when the energy storage device includes three stacked silos, each silo contains multiple energy units, and the size of each silo along the first direction is greater than or equal to one-third the size of a standard container along the first direction, and less than one-half the size of a standard container along the first direction. When the three silos are stacked, they are taller than a standard container, but the total weight of each silo containing components such as energy units is lower. With this arrangement, each silo containing components such as energy units of the energy storage device can be transported separately, and after being stacked at the place of use, the energy storage device has a higher power consumption.

[0019] In some embodiments, each of the multiple warehouse bodies accommodates multiple energy units, and the size of each warehouse body along the first direction is greater than or equal to half the size of the standard container along the first direction, and is smaller than the size of a standard container along the first direction.

[0020] The size of each of the multiple warehouse bodies along the first direction may be greater than or equal to half the size of a standard container along the first direction, and smaller than the size of a standard container along the first direction; or the size of some of the multiple warehouse bodies along the first direction may be greater than or equal to half the size of a standard container along the first direction, and smaller than the size of a standard container along the first direction.

[0021] In some embodiments, there are m warehouse bodies, the sum of the dimensions of m1 of the m warehouse bodies along the first direction is smaller than the sum of the dimensions of n standard containers along the first direction, the sum of the dimensions of m1+1 of the m warehouse bodies along the first direction is greater than the sum of the dimensions of n standard containers along the first direction, m is greater than m1, m is greater than or equal to 2, and m1 is greater than or equal to n.

[0022] In this embodiment, by setting the sum of the dimensions of m1 silos along the first direction to be less than the sum of the dimensions of n standard containers along the first direction, and m1 ≥ n, that is, by reducing the size of the silo, the total weight of the silo and the components within the silo can be reduced, which helps to improve the problem of overweight transportation, reduces the transportation cost of the energy storage device, and thus reduces the cost of using the energy storage device. On the other hand, by setting the sum of the dimensions of m1+1 silos along the first direction to be greater than the sum of the dimensions of n standard containers along the first direction, it means that the dimension of at least one silo along the first direction is made as large as possible, and the power of the energy storage device can be increased as much as possible while meeting the transportation weight. On the other hand, it is beneficial to increase the volume and power of the energy storage device, further reducing the cost of using the energy storage device.

[0023] In some embodiments, m1=1, n=1; or, m1=2, n=1; or, m1=2, n=2.

[0024] In some embodiments, the first direction is the height direction of the warehouse body, the height dimension of the warehouse body is h, and 850 mm ≤ h < 2896 mm.

[0025] In this embodiment, by setting the height of the silo to 850mm≤h<2896mm, the total weight of the silo and the components inside the silo is reduced, and the volume and power of the energy storage device can be increased as much as possible, thereby reducing the use cost of the energy storage device.

[0026] In some embodiments, 1300 mm ≤ h ≤ 2400 mm.

[0027] This is beneficial to reducing the total weight of the warehouse body and the components inside the warehouse body, and can maximize the volume and power of the energy storage device, further reducing the use cost of the energy storage device.

[0028] In some embodiments, the first direction is the height direction of the warehouse body, the dimension of the warehouse body along its length direction is consistent with the dimension of the standard container along its width direction, and the dimension of the warehouse body along its width direction is consistent with the dimension of the standard container along its width direction.

[0029] In this embodiment, by setting the dimensions of the warehouse body along its length direction to be consistent with the dimensions of the length direction of a standard container, and setting the dimensions of the warehouse body along its width direction to be consistent with the dimensions of the width direction of a standard container, it is convenient to match the transportation tools and slings of existing standard containers, reducing the transportation cost of the energy storage device, and thus reducing the use cost of the energy storage device.

[0030] In some embodiments, the energy storage device includes a thermal management module, and the thermal management module is used to manage the temperature of the plurality of energy units of the energy storage device.

[0031] In this embodiment, by providing a thermal management module, the thermal management module can manage the temperature of the energy unit and reduce the risk of the temperature of the energy unit being out of control.

[0032] In some embodiments, there are m warehouse bodies, each of which accommodates a plurality of the energy units, and the thermal management module is used to manage the temperatures of the plurality of energy units in the m warehouse bodies.

[0033] In other words, the energy storage devices share the thermal management module to form a complete system, which is conducive to saving space.

[0034] In some embodiments, there are m warehouse bodies, each of which contains a plurality of the energy units, and the control module is used to electrically control the plurality of the energy units in the m warehouse bodies.

[0035] In other words, the energy storage devices share a control module to form a complete system, which helps save space.

[0036] In some embodiments, the control module is housed in at least one of the compartments.

[0037] Here, part of the warehouse body may house the control module, or all of the warehouse body may house the control module.

[0038] In some embodiments, the thermal management module is housed in at least one of the housings.

[0039] Here, part of the warehouse body may house the thermal management module, or all of the warehouse body may house the thermal management module.

[0040] In some embodiments, at least part of the interior of the warehouse body has an energy warehouse and a control warehouse, the energy warehouse is used to accommodate at least one of the energy units, at least part of the control module and / or at least part of the thermal management module is accommodated in the control warehouse.

[0041] In this embodiment, by arranging an energy chamber and a control chamber inside at least part of the warehouse body, and arranging at least part of the control module and / or at least part of the thermal management module inside the warehouse body, the space inside the warehouse body can be fully utilized, thereby further improving the space utilization rate of the warehouse body.

[0042] In some embodiments, at least part of the control compartment and the energy compartment are arranged along the height direction of the compartment body; and / or,

[0043] At least part of the control compartment and the energy compartment are arranged along the length direction of the compartment body.

[0044] Here, some of the control compartments and the energy compartments may be arranged along the height direction of the compartment body, or all of the control compartments and the energy compartments may be arranged along the height direction of the compartment body.

[0045] Here, some of the control compartments and the energy compartments may be arranged along the length direction of the compartment body, or all of the control compartments and the energy compartments may be arranged along the length direction of the compartment body.

[0046] In some embodiments, the thermal management module is housed in at least a portion of the control compartment, and the thermal management module is located at the top of the topmost compartment body.

[0047] In this embodiment, the thermal management module is located at the top of the topmost silo. Unobstructed above the thermal management module facilitates heat dissipation from the thermal management module, thereby increasing the service life of the energy storage device. This also helps lower the overall center of gravity of the individual silos, contributing to transportation safety. Furthermore, the design of a separate silo from the energy silo improves the thermal insulation of the energy silo. The thermal management module shields the top heat radiation, reducing its impact on the interior of the energy silo.

[0048] In some embodiments, at least a portion of the control compartment contains the control module; the control module and the energy compartment are arranged along the height direction of the compartment body; or,

[0049] The control module and the energy bin are arranged along the length direction of the bin body.

[0050] The operating part is highly ergonomically designed. Maintenance personnel can reach the operating handle of the control part by standing on one side of the warehouse, which is convenient for maintenance and inspection. At the same time, the control warehouse is located at the top, which helps to shorten the length of the high-voltage and low-voltage wiring harnesses connecting to the upper warehouse, thereby reducing costs.

[0051] That is to say, the control module can be located at the left end of the energy bin, or at the right end of the energy bin, or in the middle of the two energy bins along the length direction.

[0052] In some embodiments, at least a portion of the bin body comprises a first partition;

[0053] The first partition is provided between the energy compartment and the control compartment, and the energy compartment and the control compartment share the first partition; and / or,

[0054] There are multiple control compartments, and the first partition is arranged between adjacent control compartments. The adjacent control compartments share the first partition.

[0055] Here, the first partition is beneficial to improving the structural strength of the warehouse body, and is also beneficial to improving the sealing performance and thermal insulation performance of the energy warehouse.

[0056] In some embodiments, the interior of the first partition is filled with a heat insulating medium.

[0057] The heat-insulating medium is beneficial to improving the structural strength of the first partition, and can also play a flame retardant and heat-insulating effect, which is beneficial to reducing the heat loss of the energy bin and the impact of external heat on the energy units in the energy bin.

[0058] In some embodiments, the size of the housing containing the thermal management module along the first direction is larger than the size of other housings along the first direction.

[0059] This increases the space within the housing housing the thermal management module, thereby reducing the impact of the thermal management module on the energy unit's storage volume. This ensures that the housing has sufficient space to accommodate both the energy unit and the thermal management module. Furthermore, it can accommodate thermal management modules with higher cooling capacity, improving thermal management capabilities.

[0060] In some embodiments, at least part of the control module is disposed outside the chamber; and / or,

[0061] At least a portion of the thermal management module is disposed outside the housing.

[0062] By arranging at least part of the control module outside the warehouse, the influence of the control module on the energy unit can be reduced to a certain extent, and the control module will not occupy space inside the warehouse.

[0063] By arranging at least part of the thermal management module outside the warehouse, the impact of the thermal management module on the energy unit can be reduced to a certain extent, and the thermal management module will not occupy space inside the warehouse.

[0064] In some embodiments, the energy storage device includes a pipeline bin, which is used to accommodate at least part of the connecting pipelines between the control module, the thermal management module or the energy unit.

[0065] In this embodiment, the energy storage device is provided with a pipeline warehouse, which is used to accommodate at least part of the connecting pipelines between the control module, the thermal management module and the energy unit, which is convenient for wiring and piping, and is conducive to making the layout of the connecting pipelines reasonable and easy to repair and replace.

[0066] In some embodiments, each of the warehouse bodies is provided with the pipeline warehouse; or, some of the warehouse bodies are provided with the pipeline warehouse, and another part of the warehouse bodies are not provided with the pipeline warehouse.

[0068] That is to say, the pipeline bin can be at the left end of the energy bin, or at the right end of the energy bin, or in the middle of the two energy bins along the length direction.

[0069] In some embodiments, at least a portion of the silo body includes a second partition, the second partition is disposed between the energy silo and the pipeline silo, and the energy silo and the pipeline silo share the second partition.

[0070] Here, the second partition is beneficial to improving the structural strength of the warehouse body, and is also beneficial to improving the sealing performance and thermal insulation performance of the energy warehouse.

[0071] In some embodiments, at least a portion of the silo body includes a third partition, the third partition is disposed between the pipeline silo and at least a portion of the control silo, and the pipeline silo and at least a portion of the control silo share the third partition.

[0072] Here, the third partition is beneficial to improving the structural strength of the warehouse body, and is also beneficial to improving the sealing performance and thermal insulation performance of part of the control warehouse.

[0073] In some embodiments, the multiple warehouse bodies include a first warehouse body and a second warehouse body, the first warehouse body is located above the second warehouse body, at least the first warehouse body accommodates multiple energy units, the thermal management module is arranged in the first warehouse body and located on top of the multiple energy units, and the control module is arranged in the first warehouse body and / or the second warehouse body.

[0074] In this embodiment, by accommodating the thermal management module in the control compartment of the first compartment located above and the control module in the control compartment of the second compartment located below, the interference of the thermal management module on the control module can be reduced. In addition, the location of the thermal management module in the first compartment above is further conducive to the heat dissipation of the thermal management module, so that the thermal management module can have more heat dissipation channels, thereby improving the temperature control effect of the thermal management module. At the same time, it is conducive to reducing the overall center of gravity height of a single energy storage cabinet, which is beneficial to transportation safety. In addition, the design of the compartment separated from the energy compartment is conducive to improving the thermal insulation effect of the energy compartment. At the same time, the thermal management module blocks the heat radiation from the top, reducing the impact of heat radiation on the interior of the energy compartment.

[0075] In some embodiments, at least the second storage body accommodates a plurality of the energy units, and the control module is disposed in the second storage body and located on top of the plurality of the energy units in the second storage body.

[0076] In this embodiment, by placing the control module within the second silo, located above the multiple energy units within the second silo, the operating area is ergonomically designed. Maintenance personnel standing on the side of the silo can easily reach the control handle, facilitating maintenance and inspection. Furthermore, the top location of the control silo shortens the length of the high-voltage and low-voltage wiring harnesses connecting to the upper silo, thereby reducing costs. Furthermore, it helps lower the overall center of gravity of each silo, improving transportation safety.

[0077] In some embodiments, at least a portion of the top wall and / or side walls of the storage body are provided with ventilation holes, and the ventilation holes are used for ventilating the thermal management module.

[0078] In this embodiment, the vents are located on the top wall and / or side wall of the bin body, which is beneficial to heat dissipation of the thermal management module, so that the thermal management module can have more heat dissipation channels and improve the temperature control effect of the thermal management module.

[0079] In some embodiments, each of the warehouse bodies accommodates multiple energy units, at least part of the warehouse bodies include a first connector, the first connector is electrically connected to the control module, each of the warehouse bodies includes a second connector, the second connector is electrically connected to multiple energy units, and the first connector is used to cooperate with each of the second connectors.

[0080] In this embodiment, the first connector cooperates with each second connector to achieve a quick connection between the control module and the energy unit, making the connection between the control module and the energy unit more convenient.

[0081] In some embodiments, each of the compartments contains a plurality of the energy units, the energy storage device includes a plurality of battery devices, each of the battery devices includes a thermal management component and a plurality of the energy units, and the thermal management component is used to regulate the temperature of the energy units;

[0082] At least part of the warehouse body includes a third connector, each of the warehouse bodies includes a fourth connector, the third connector is connected to the thermal management module, the fourth connector is connected to the thermal management component, and the third connector is used to cooperate with each of the fourth connectors.

[0083] In this embodiment, the third connector and the fourth connector cooperate to achieve rapid connection between the thermal management component and the thermal management module, thereby facilitating installation of the thermal management module.

[0085] Here, by arranging the main pipe above the multiple battery devices, or below the multiple battery devices, the liquid cooling pipe can be shortened, thereby reducing costs and improving cooling efficiency.

[0086] In some embodiments, the control module includes at least one of a main control module, a power distribution module, a general control module, and a fire control module.

[0087] The main control module controls the input and output of high-voltage electrical energy to the energy units within the warehouse. The master control module controls the switching operations of the main control module within the warehouse. The fire control module controls the operation of firefighting components, such as fire extinguishers, when a fire occurs due to a temperature imbalance within the warehouse. The power distribution module electrically connects the main control module, master control module, and fire control module to ensure continuity among these modules and maintain their normal operation.

[0088] In some embodiments, the energy unit is a battery cell, and the weight of a single energy unit is 5 kg to 60 kg.

[0089] The weight of the energy unit is appropriate so that an appropriate amount of energy units can be placed in the warehouse, and the energy density is moderate while meeting the transportation needs.

[0090] In some embodiments, the energy storage device includes an energy storage cabinet, which includes the storage body and components disposed in the storage body. The weight of the energy storage cabinet is M, and M is less than or equal to 35 tons.

[0091] To ensure that a single energy storage cabinet meets the transportation limit requirements of some countries, the overall weight of the energy storage cabinet is controlled within 35 tons, and the integration of the energy storage cabinet is as high as possible to reduce the workload of on-site installation; at the same time, the energy per unit area is increased, reducing customer cost investment.

The weight of the energy storage cabinet is M, and the total weight of the energy units in the warehouse body is M1, (M1 / M)×100%≥60%.

[0093] In this way, on the one hand, the weight proportion of energy units in the unit volume of the warehouse can be increased, and the power of the energy storage device per unit volume can be increased; on the other hand, during the transportation of the energy storage device, more energy units that contribute to the stored energy and are difficult to produce and cannot be completed at the destination are transported, while other structures can be produced at a place closer to the destination without having to be transported or with reduced transportation. After the warehouse is assembled into the energy storage device, it is beneficial to reduce the transportation cost of the assembled energy storage device.

[0094] In some embodiments, (M1 / M)×100%≥80%.

[0095] This is further beneficial to reducing the transportation cost of the assembled energy storage device.

The weight of the energy storage cabinet is M. Multiple battery devices are arranged in the warehouse body, and the battery devices include a box body and multiple energy units. Multiple energy units are accommodated in the box body. The total weight of the battery devices is M2, 70%≤(M2 / M)×100%≤90%.

[0097] It can take into account both the energy density of the energy storage cabinet and the structural strength of the warehouse body, making the warehouse body more practical.

[0098] In some embodiments, the volume of the chamber is V, the total volume of the energy units in the chamber is V1, and (V1 / V)×100%≥30%.

[0099] On the one hand, the volume ratio of energy units in the unit volume of the warehouse can be increased, and the power of the energy storage device per unit volume can be increased; on the other hand, during the transportation of the energy storage device, more energy units that contribute to the stored energy and are difficult to produce and cannot be completed at the destination are transported, while other functional components of the energy storage device, such as control components, can be produced at a location closer to the destination without having to be transported or with reduced transportation. After the warehouse is assembled into the energy storage device, it is beneficial to reduce the transportation cost of the assembled energy storage device.

[0100] In some embodiments, (V1 / V)×100%≥50%.

[0101] This is further beneficial to reducing the transportation cost of the assembled energy storage device.

[0102] In some embodiments, the volume of the warehouse is V, and multiple battery devices are arranged in the warehouse. The battery device includes a box and multiple energy units. The multiple energy units are accommodated in the box. The total volume of the battery device is V2, 50%≤(V2 / V)×100%≤80%.

[0103] It can take into account both the energy density of the energy storage device and the structural strength of the warehouse body, and the practicality of the warehouse body is stronger.

[0104] In some embodiments, the energy storage device includes an energy storage cabinet, which includes the silo and components disposed in the silo. The energy of the energy storage cabinet is E, the dimension of the silo along the length direction is a, the dimension of the silo along the width direction is b, and the energy consumption of the energy storage cabinet is 250KW / m 2 ≤E / (a×b)≤700KW / m 2 .

[0105] The energy density of the energy storage device 100 and the mass setting of the warehouse body 10 are taken into consideration, thereby improving the practicality of the energy storage device 100 and facilitating the transportation of the energy storage device 100.

[0106] In some embodiments, 450KW / m 2 ≤E / (a×b)≤600KW / m 2 .

[0107] The energy density of the energy storage device 100 and the mass setting of the warehouse body 10 can be further improved, making transportation of the energy storage device 100 easier.

[0108] In some embodiments, along the height direction of the bin body, two adjacent bin bodies are connected by welding, snapping, locking or by fasteners.

[0114] In some embodiments, there are m warehouse bodies, the first direction is the height direction of the warehouse bodies, and the energy storage device further includes a connecting mechanism configured to connect two adjacent warehouse bodies along the height direction of the warehouse bodies;

[0115] In which, the connecting mechanism includes a support member, which is arranged between two adjacent warehouse bodies along the height direction; the sum of the dimensions of m1 warehouse bodies among the m warehouse bodies along the height direction and the sum of the dimensions of m1-1 support members along the height direction is less than the sum of the dimensions of n standard containers in the height direction, and the sum of the dimensions of m1+1 warehouse bodies among the m warehouse bodies along the height direction and the sum of the dimensions of m1 support members along the height direction is greater than the sum of the dimensions of n standard containers in the height direction.

[0116] Connecting the silos through a connecting mechanism makes stacking the silos more stable. During transportation, the sum of the height dimensions of m1 silos plus the sum of the height dimensions of the supports between two adjacent silos in the m1 silo is less than the sum of the heights of n standard containers. The sum of the height dimensions of m1+1 silos in the m silo plus the sum of the height dimensions of m1 supports is greater than the sum of the height dimensions of n standard containers. This helps increase the volume and energy capacity of the energy storage device, further reducing its operating costs.

[0117] In some embodiments, the first direction is the height direction of the warehouse body, and along the height direction of the warehouse body, the heights of some of the multiple warehouse bodies are not equal to the heights of another part of the warehouse bodies; or the dimensions of the multiple warehouse bodies along the height direction of the warehouse body are equal.

[0118] In this way, it is easy to improve the flexibility of warehouse capacity and match different needs.

[0119] This simplifies the manufacturing process and reduces costs.

[0120] In some embodiments, the first direction is the height direction of the warehouse body, the standard container is a 20-foot standard container, and the height of the standard container is 2896 mm, 2591 mm, or 2438 mm.

[0121] In some embodiments, at least part of the interior of the warehouse body has an energy warehouse and a control warehouse, the energy warehouse is used to accommodate at least one of the energy units, at least part of the control module and / or at least part of the thermal management module is accommodated in the control warehouse; the warehouse body is provided with a first warehouse door on at least one side along the width direction, and the control warehouse and / or the pipeline warehouse are provided with a second warehouse door on at least one side along the width direction.

[0122] In this embodiment, it is helpful to reduce the land waste of traditional warehouses that must reserve maintenance channels of more than 3m between adjacent warehouses. Only normal paint repair channels need to be reserved between the grid warehouses, which increases the user's land investment returns and increases the user's energy benefits per unit area.

[0123] The embodiment of the present disclosure further provides an energy storage device, the energy storage device comprising a warehouse body and a plurality of energy units, wherein the plurality of energy units are accommodated in the warehouse body;

[0124] The size of the warehouse body along the first direction is greater than one-third of the size of a standard container along the first direction, and less than one-half of the size of the standard container along the first direction; or,

[0125] The size of the warehouse body along the first direction is greater than half the size of a standard container along the first direction, and smaller than the size of one standard container along the first direction.

[0126] The energy storage device provided in the embodiment of the present disclosure can reduce the total weight of the warehouse body and the components inside the warehouse body by reducing the size of the warehouse body, which is beneficial to improving the problem of overweight transportation, reducing the transportation cost of the energy storage device, and thus reducing the use cost of the energy storage device.

[0150] Unless otherwise specified, all technical features and optional technical features disclosed herein can be combined with each other to form a new technical solution.

[0151] With the development of clean energy, more and more devices are using electricity as a driving force. Consequently, power batteries, such as lithium-ion batteries, that can store large amounts of electricity and undergo multiple charge and discharge cycles are rapidly developing. These batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric vehicles, as well as in aerospace and other fields.

[0152] In the embodiment of the present disclosure, the energy unit may be a secondary battery. A secondary battery refers to an energy unit that can be continuously used by activating active materials by charging after the energy unit is discharged.

[0153] The energy unit can be a lithium-ion battery, a sodium-ion battery, a sodium-lithium-ion battery, a lithium metal battery, a sodium metal battery, a lithium-sulfur battery, a magnesium-ion battery, a nickel-hydrogen battery, a nickel-cadmium battery, a lead-acid battery, etc., which is not limited in the embodiments of the present disclosure.

[0154] An energy cell typically includes an electrode assembly. As an example, the electrode assembly includes a positive electrode, a negative electrode, and a separator, which is positioned between the positive and negative electrodes. During the charge and discharge process of the energy cell, active ions (such as lithium ions) are embedded and released back and forth between the positive and negative electrodes. The separator is positioned between the positive and negative electrodes to prevent short circuits between the positive and negative electrodes while allowing active ions to pass through.

[0155] In some embodiments, the positive electrode may be a positive electrode sheet, which may include a positive electrode current collector and a positive electrode active material disposed on at least one surface of the positive electrode current collector.

[0156] As an example, the positive electrode current collector has two surfaces facing each other in its thickness direction, and the positive electrode active material is provided on either or both of the two facing surfaces of the positive electrode current collector.

[0157] As an example, the positive electrode current collector may be a metal foil, a conductive polymer material, a carbon material or a composite current collector. For example, as the metal foil, a pure metal, an alloy, a surface-treated metal may be used, including but not limited to stainless steel, copper, aluminum, nickel, nickel, titanium or silver. The composite current collector may include a polymer material base layer and a metal layer. The composite current collector may be formed by forming a metal material (aluminum, aluminum alloy, nickel, nickel alloy, titanium, titanium alloy, silver and silver alloy, etc.) on a polymer material substrate (such as a substrate of polypropylene, polyethylene terephthalate, polybutylene terephthalate, polystyrene, polyethylene, etc.).

[0158] As an example, the positive electrode active material may include at least one of the following materials: lithium-containing phosphates, lithium transition metal oxides, and their respective modified compounds. However, the present disclosure is not limited to these materials, and other conventional materials that can be used as positive electrode active materials for batteries may also be used.

[0159] In some embodiments, the negative electrode may be a negative electrode sheet, and the negative electrode sheet may include a negative electrode current collector.

[0160] As an example, the negative electrode current collector may be a metal foil, a conductive polymer material, a carbon material, or a composite current collector. For example, as the metal foil, a pure metal, an alloy, or a surface-treated metal may be used, including but not limited to stainless steel, copper, aluminum, nickel, nickel, titanium, or silver. The composite current collector may include a polymer material base layer and a metal layer. The composite current collector may be formed by forming a metal material (copper, copper alloy, nickel, nickel alloy, titanium, titanium alloy, silver, and silver alloy, etc.) on a polymer material substrate (such as a substrate of polypropylene, polyethylene terephthalate, polybutylene terephthalate, polystyrene, polyethylene, etc.).

[0161] As an example, the negative electrode sheet may include a negative electrode current collector and a negative electrode active material disposed on at least one surface of the negative electrode current collector.

[0162] In some embodiments, the material of the positive electrode current collector may be aluminum, and the material of the negative electrode current collector may be copper.

[0163] In some embodiments, the electrode assembly further includes a separator disposed between the positive electrode and the negative electrode.

[0164] In some embodiments, the separator is a separator. The present disclosure has no particular limitation on the type of separator, and any known separator with a porous structure having good chemical stability and mechanical stability can be selected.

[0165] As an example, the primary material of the separator can be selected from at least one of glass fiber, non-woven fabric, polyethylene, polypropylene, polyvinylidene fluoride, and ceramic. The separator can be a single-layer film or a multi-layer composite film, without particular limitation. When the separator is a multi-layer composite film, the materials of each layer can be the same or different, without particular limitation. The separator can be a separate component located between the positive and negative electrodes, or it can be attached to the surfaces of the positive and negative electrodes. The surface of the separator can also be coated with an inorganic particle coating, an organic particle coating, or an organic / inorganic composite coating.

[0166] In some embodiments, the separator is a solid electrolyte, which is disposed between the positive electrode and the negative electrode and serves to transport ions and isolate the positive and negative electrodes.

[0167] In some embodiments, the energy cell further includes an electrolyte, which acts as a conductive medium between the positive and negative electrodes. The present disclosure does not specifically limit the type of electrolyte, and the electrolyte may be selected based on needs. The electrolyte may be liquid, gel, or solid.

[0168] The electrode assembly may be a wound structure, a laminated structure, or a mixed structure of wound and laminated structures.

[0169] In some embodiments, the electrode assembly is a wound structure, wherein the positive electrode sheet and the negative electrode sheet are wound into the wound structure.

[0170] In some embodiments, the electrode assembly is a laminate structure.

[0171] As an example, multiple positive electrode sheets and multiple negative electrode sheets can be provided respectively, and the multiple positive electrode sheets and the multiple negative electrode sheets can be alternately stacked.

[0172] As an example, a plurality of positive electrode sheets may be provided, and the negative electrode sheet may be folded to form a plurality of stacked folded segments, with a positive electrode sheet being sandwiched between adjacent folded segments.

[0173] As an example, both the positive electrode sheet and the negative electrode sheet are folded to form a plurality of stacked folded segments.

[0174] As an example, a plurality of separators may be provided, each of which is disposed between any adjacent positive electrode sheets or negative electrode sheets.

[0175] As an example, the separator may be provided continuously, and may be provided between any adjacent positive electrode sheets or negative electrode sheets by folding or winding.

[0176] In some embodiments, the shape of the electrode assembly can be cylindrical, flat, or polygonal.

[0177] In some embodiments, the electrode assembly is provided with tabs that can conduct current from the electrode assembly. The tabs include a positive tab and a negative tab.

[0178] In some embodiments, the energy unit may include an outer shell. The outer shell may be a steel shell, an aluminum shell, a plastic shell (such as polypropylene), a composite metal shell (such as a copper-aluminum composite shell) or an aluminum-plastic film. In some embodiments, the outer shell may be a sealed structure or a non-sealed structure. As an example, when the outer shell is a non-sealed structure, the outer shell serves to protect the electrode assembly, and a sealed bag is further included between the outer shell and the electrode assembly, and the sealed bag is used to encapsulate the electrode assembly and the electrolyte. Specifically, the sealed bag may be a bag-shaped insulating member or an aluminum-plastic film. When the outer shell is a sealed structure, it is used to encapsulate components such as the electrode assembly and the electrolyte.

[0179] As an example, the energy unit can be a cylindrical energy unit, a prismatic energy unit, a soft-pack energy unit or an energy unit of other shapes. The prismatic energy unit includes a square shell energy unit, a blade-shaped energy unit, a polygonal prismatic battery, and a polygonal prismatic battery such as a hexagonal prismatic battery, etc. There is no special limitation in the present disclosure.

[0180] In some embodiments, the housing includes an end cap and a shell, wherein the shell has an opening and the end cap covers the opening. The shell may have one or more openings. One or more end caps may also be provided.

[0181] In some embodiments, the housing is provided with at least one electrode terminal, which is electrically connected to the tab. The electrode terminal may be directly connected to the tab or indirectly connected to the tab via a current collecting member. The electrode terminal may be provided on an end cap or on the housing.

[0182] In some embodiments, the energy storage device includes an energy storage container, etc.

[0183] Power stations are increasingly demanding higher areal energy density for energy storage devices. Therefore, to increase power output, the total weight of the storage tank and its components must be reduced accordingly. However, energy storage devices must be transported from their production site to their intended destination via land and / or sea transport, which often has weight restrictions. This creates a conflict between increasing energy density and the weight of the storage device.

[0184] In view of this, the embodiments of the present disclosure propose a new technical solution. The technical solution described in the embodiments of the present disclosure is applicable to energy storage devices, energy storage systems including energy storage devices, and charging networks.

[0185] 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. Energy storage devices can store electrical energy as needed and output it at the appropriate time. For example, an energy storage device can store electrical energy during periods of low electricity consumption and provide it to relevant users or electrical equipment during periods of peak electricity consumption. The energy storage system provided in the embodiments of the present disclosure can be any power system that requires an energy storage device.

[0186] Please refer to Figure 1, which is a schematic diagram of the structure of a charging network provided in one embodiment of the present disclosure. This embodiment of the present disclosure provides 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 or energy storage system 2000, which is electrically connected to charging piles 200 and is used to provide electrical energy to charging piles 200.

[0187] It should be noted that the charging pile 200 is electrically connected to the energy unit 2 in the energy storage device 100 via a cable, and the energy unit 2 can provide its stored electrical energy to the charging pile 200. The charging pile 200 has one or more connectors, which are used to connect to electrical equipment (such as vehicles) to replenish energy to the electrical equipment. The application of the energy storage device 100 in the charging network 1000 can effectively improve the reliability of the charging network 1000 and also help improve the flexibility of the charging network 1000 during deployment.

[0188] The energy storage device 100 may be located inside the charging pile 200 (eg, an integrated storage and charging device), or may be located outside the charging pile 200 .

[0189] 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 .

[0190] The energy storage device 100 may include multiple warehouse bodies 10 and multiple energy units 2. The multiple energy units 2 are accommodated in at least one warehouse body 10. The energy unit 2 is electrically connected to the charging pile 200 so that the energy unit 2 provides electrical energy to the charging pile 200.

[0191] 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 .

This embodiment of the present disclosure provides an energy storage system 2000. Energy storage system 2000 includes a power conversion device 300. Power conversion device 300 can be electrically connected to a power generation device 3000 and an energy storage device 100 to convert the electrical power provided by power generation device 3000. Power conversion device 300 converts the electrical energy provided by power generation device 3000 into energy storage device 100 for storage.

[0193] The power conversion device 300 is connected 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 generated electrical energy is stored in the energy storage device 100 via the power conversion device. The energy storage system 2000 employs the energy storage device 100, which effectively improves the operational reliability of the energy storage system 2000. In a specific implementation, the power generation equipment may include solar panels, hydropower generation equipment, thermal power generation equipment, etc. The specific type of power generation equipment is not limited in this disclosure.

[0197] The warehouse body 10 is generally a rectangular parallelepiped structure, with both its length and width parallel to the horizontal plane. The length of the warehouse body 10 is parallel to the longest side of the rectangular parallelepiped structure. The height of the warehouse body 10 is perpendicular to the ground. For example, as shown in Figures 3 and 5 , the length of the warehouse body 10 is represented by X, the width of the warehouse body 10 is represented by Y, and the height of the warehouse body 10 is represented by Z.

[0198] The plurality of bin bodies 10 are arranged along the first direction of the bin body 10 , which can be understood as the plurality of bin bodies 10 being stacked or connected along the first direction of the bin body 10 .

[0199] Exemplarily, the first direction is the length direction, width direction or height direction of the silo body 10. The embodiment of the present disclosure is described by taking the first direction as the height direction as an example.

[0200] Referring to Figures 3 and 6 , the number of silos 10 in the energy storage device 100 can be any number greater than two. For example, the energy storage device 100 may include two silos 10 stacked in a vertical direction. Another example is the energy storage device 100 including three silos 10 stacked in a vertical direction. For example, the sum of the heights of all stacked silos 10 is less than or equal to the sum of the heights of eight standard containers stacked together.

[0201] The energy storage device 100 further includes a plurality of energy units 2 , which are used to provide or store electrical energy.

[0202] Here, the energy unit 2 may be a battery cell, or may be a battery device 80 formed by electrically connecting a plurality of battery cells.

[0203] 18 , a plurality of energy units 2 may be formed into multiple layers and / or multiple columns of battery devices 80 , and each row or column of battery devices 80 includes a plurality of battery devices 80 .

[0204] The battery apparatus 80 mentioned in the embodiments of the present disclosure may include one or more battery cell assemblies for providing voltage and capacity. The battery cell assembly may include multiple battery cells, which are connected in series, parallel, or hybrid via a busbar.

[0205] In some embodiments, a battery cell assembly is generally formed by arranging a plurality of battery cells.

[0206] As an example, the battery cell assembly may be a battery module, which is formed by arranging and fixing multiple battery cells to form an independent module. As an example, the battery module may be formed by bundling multiple battery cells with a cable tie.

[0207] In some embodiments, the battery device 80 may be a battery pack, which includes a case 81 and one or more battery cell assemblies, wherein the battery cell assemblies are housed in the case 81 .

[0208] As an example, the battery cell assembly may be a battery module, and the battery cell assembly may be accommodated in the box body 81 by fixing the battery module in the box body 81 .

[0209] As an example, the battery cell assembly may also be housed in the box body 81 by directly fixing a plurality of battery cells to the box body 81 .

[0210] As an example, referring to Figure 18 , the housing 81 may include a first housing 811 and a second housing 812 . The first housing 811 and the second housing 812 engage to form an enclosed space within the housing 81 for housing the battery cell assembly. Enclosed here means covered or closed, and can be either sealed or unsealed. The first housing 811 can be a top cover or a bottom plate.

[0211] As an example, the box body 81 may include a top cover, a frame, and a bottom plate. The top cover and the bottom plate are respectively connected to the frame, so that a closed space is formed inside the box body 81 to accommodate the battery cell assembly.

[0212] Exemplarily, a plurality of energy units 2 are accommodated in at least one warehouse body 10 .

[0213] That is to say, part of the warehouse body 10 may contain the energy unit 2, while another part of the warehouse body 10 may not contain the energy unit 2; or all of the warehouse body 10 may contain the energy unit 2.

[0214] In the embodiment where the energy unit 2 is accommodated in part of the warehouse bodies 10 , the energy unit 2 may be accommodated in only one of the warehouse bodies 10 , or may be accommodated in multiple warehouse bodies 10 .

[0215] The compartment 10 contains a plurality of energy units 2, which may be battery modules or battery packs.

[0216] In some embodiments, referring to FIG. 4 , the energy storage device 100 includes a control module 30 , and the control module 30 is used to electrically control the multiple energy units 2 of the energy storage device 100 .

[0217] In this embodiment, by providing a control module 30 , the control module 30 can control the input or output of electrical energy of the energy unit 2 , thereby achieving electrical control of the energy unit 2 .

[0218] Exemplarily, a dimension of at least one of the plurality of warehouse bodies 10 along the first direction is smaller than a dimension of a standard container along the first direction.

[0219] Here, the size of part of the warehouse body 10 along the first direction may be smaller than the size of a standard container along the first direction, or the size of all the warehouse bodies 10 along the first direction may be smaller than the size of a standard container along the first direction.

[0220] Referring to Figures 3 and 6 , the length dimension a of the silo 10 is the distance between its two ends along the length direction; the width dimension b of the silo 10 is the distance between its two ends along the width direction; and the height dimension h of the silo 10 is the distance between its two ends along the height direction. Dimensions a, b, and h represent the maximum dimensions of the outer contour of the silo 10 in the corresponding directions. The silo 10 can include eight corner fittings and six walls. The eight corner fittings are located at the eight corners of the silo's rectangular structure and protrude from the walls of the silo 10. The total span of the two corner fittings arranged along the height direction is the height of the silo 10, the total span of the two corner fittings arranged along the length direction is the length of the silo 10, and the total span of the two corner fittings arranged along the width direction is the width of the silo 10. When calculating the dimensions of the silo 10, pipes and cables connected to the silo 10 and located outside the silo 10 are not included in the dimensions of the silo 10.

[0221] A standard container may be a standard container size used in transportation, such as 10 feet, 20 feet, 30 feet, 40 feet, or 45 feet, which meets corresponding standards and has corresponding dimensions for length, width, and height. Standard containers may refer to GB / T1413-2023 Series 1 Container Classification, Dimensions, and Rated Weights.

[0222] 10 feet can include: the length dimension is 2991mm, with a tolerance of 0mm-5mm; the width dimension is 2438mm, with a tolerance of 0mm-5mm; and the height dimension is 2438mm or less than 2438mm; the tolerance is 0mm-5mm.

[0223] 20 feet can include: the length dimension is 6058mm, with a tolerance of 0mm-6mm; the width dimension is 2438mm, with a tolerance of 0mm-5mm; and the height dimension is 2896mm, 2591mm or not more than 2438mm; the tolerance is 0mm-5mm.

[0224] 30 feet can include: the length dimension is 9125mm, with a tolerance of 0mm-10mm; the width dimension is 2438mm, with a tolerance of 0mm-5mm; and the height dimension is 2896mm, 2591mm or not more than 2438mm; the tolerance is 0mm-5mm.

[0225] 40 feet can include: the length dimension is 12192mm, with a tolerance of 0mm-10mm; the width dimension is 2438mm, with a tolerance of 0mm-5mm; and the height dimension is 2896mm, 2591mm or not more than 2438mm; the tolerance is 0mm-5mm.

[0226] 45 feet can include: the length dimension is 13716mm, with a tolerance of 0mm-10mm; the width dimension is 2438mm, with a tolerance of 350mm-5mm; and the height dimension is 2591mm or 2896mm; the tolerance is 0mm-5mm.

[0227] In the embodiment of the present disclosure, for warehouse bodies 10 of various sizes, sizes within the range of ±1%, ±2%, ±3%, ±4%, and ±5% thereof can be regarded as sizes within the tolerance range.

[0228] The size of the warehouse body 10 along the first direction is set to be smaller than the size of a standard container along the first direction. By reducing the size of the warehouse body 10, the total weight of the warehouse body 10 containing components such as the energy unit 2 can be reduced, which is beneficial to improving the problem of overweight transportation and reducing the transportation cost of the energy storage device 100.

[0229] Exemplarily, the sum of the dimensions of the plurality of warehouse bodies 10 along the first direction is set to be greater than the sum of the dimensions of one or more standard containers along the first direction.

[0230] In other words, on the one hand, the sum of the dimensions of the multiple silos 10 along the first direction is set to be greater than the sum of the dimensions of one or more standard containers along the first direction. This means that the dimension of at least one silo 10 along the first direction is maximized, thereby maximizing the power capacity of the energy storage device 100 while still meeting the transport weight. On the other hand, this helps increase the volume and power capacity of the energy storage device 100, further reducing the operating cost of the energy storage device 100.

[0231] Of course, in other embodiments, the sum of the dimensions of the plurality of warehouse bodies 10 along the first direction may be equal to the sum of the dimensions of one or more standard containers along the first direction.

[0232] In some embodiments, the first direction is the height direction of the warehouse body 10, the standard container is a 20-foot standard container, and the height of the standard container is 2896 mm, 2591 mm, or 2438 mm.

[0233] The sum of the height dimensions of m1 warehouse bodies 10 is less than the height of a 20-foot standard container, 2896 mm, 2591 mm, or 2438 mm; the sum of the height dimensions of m1+1 warehouse bodies 10 is greater than the height of a 20-foot standard container, 2896 mm, 2591 mm, or 2438 mm.

[0234] In some embodiments, a dimension of at least one of the plurality of silos 10 along the first direction is greater than or equal to one-third the dimension of a standard container along the first direction, and is smaller than the dimension of one standard container along the first direction.

[0235] For example, multiple energy units 2 may be placed in each warehouse body 10, or multiple energy units 2 may be placed in some warehouse bodies 10, and no energy unit 2 may be placed in other warehouse bodies 10. The control module 30 may be placed in the warehouse body 10 without the energy unit 2. Of course, the control module 30 may also be placed in the warehouse body 10 with multiple energy units 2.

[0236] For example, the size of each warehouse body 10 among the multiple warehouse bodies 10 along the first direction may be greater than or equal to one-third of the size of a standard container along the first direction, and smaller than the size of a standard container along the first direction; or the size of some warehouse bodies 10 among the multiple warehouse bodies 10 along the first direction may be greater than or equal to one-third of the size of a standard container along the first direction, and smaller than the size of a standard container along the first direction.

[0237] Exemplarily, the energy storage device 100 may include three warehouse bodies 10 , which are stacked along a first direction, and the sum of the dimensions of the three warehouse bodies 10 along the first direction is greater than the dimension of a standard container along the first direction.

[0238] Exemplarily, the energy storage device 100 may include two warehouse bodies 10 , which are stacked along a first direction, and the sum of the dimensions of the two warehouse bodies 10 along the first direction is greater than the dimension of a standard container along the first direction.

[0239] The size of the warehouse body 10 cannot be infinitely small. When the size of the warehouse body 10 along the first direction is greater than or equal to one-third of the size of a standard container along the first direction, the energy storage device 100 has high manufacturability, high volume energy density, and is more convenient to transport and install.

[0240] In some embodiments, a size of at least one of the plurality of warehouse bodies 10 along the first direction is greater than or equal to half the size of a standard container along the first direction, and smaller than the size of one standard container along the first direction.

[0241] For example, multiple energy units 2 may be placed in each warehouse body 10, or multiple energy units 2 may be placed in some warehouse bodies 10, and no energy unit 2 may be placed in other warehouse bodies 10. The control module 30 may be placed in the warehouse body 10 without the energy unit 2. Of course, the control module 30 may also be placed in the warehouse body 10 with multiple energy units 2.

[0242] For example, the size of each warehouse body 10 among the multiple warehouse bodies 10 along the first direction may be greater than or equal to half the size of a standard container along the first direction, and smaller than the size of a standard container along the first direction; or the size of some warehouse bodies 10 among the multiple warehouse bodies 10 along the first direction may be greater than or equal to half the size of a standard container along the first direction, and smaller than the size of a standard container along the first direction.

[0243] When the size of the silo 10 along the first direction is greater than or equal to half the size of a standard container along the first direction, the energy storage device 100 has high manufacturability, high volume energy density, and is more convenient to transport and install. For example, when the energy storage device 100 includes two stacked silos 10, each silo 10 contains multiple energy units 2, and the size of each silo 10 along the first direction is greater than or equal to half the size of a standard container along the first direction, and is smaller than the size of a standard container along the first direction. When the two silos 10 are stacked, they are taller than a standard container, but the weight of each silo 10 containing components such as energy units 2 is lower. With this arrangement, each silo 10 containing components such as energy units 2 of the energy storage device 100 can be transported separately, and after being stacked at the place of use, the energy storage device 100 has a higher power capacity.

[0244] In some embodiments, the size of at least one of the plurality of silos 10 along the first direction is greater than or equal to one-third the size of a standard container along the first direction, and less than one-half the size of a standard container along the first direction.

[0245] For example, multiple energy units 2 may be placed in each warehouse body 10, or multiple energy units 2 may be placed in some warehouse bodies 10, and no energy unit 2 may be placed in other warehouse bodies 10. The control module 30 may be placed in the warehouse body 10 without the energy unit 2. Of course, the control module 30 may also be placed in the warehouse body 10 with multiple energy units 2.

[0246] When the size of the silo 10 along the first direction is greater than or equal to one-third the size of a standard container along the first direction, the energy storage device 100 has high manufacturability, high volumetric energy density, and is more convenient to transport and install. For example, when the energy storage device 100 includes three stacked silos 10, each silo 10 contains multiple energy units 2, and the size of each silo 10 along the first direction is greater than or equal to one-third the size of a standard container along the first direction, and less than one-half the size of a standard container along the first direction. When the three silos 10 are stacked, they are taller than a standard container, but the weight of each silo 10 containing components such as energy units 2 is lower. With this arrangement, each silo 10 containing components such as energy units 2 of the energy storage device 100 can be transported separately, and after being stacked at the location of use, the energy storage device 100 has a higher charge capacity.

[0247] Of course, in other embodiments, only one warehouse body 10 may meet the above size requirements, and other warehouse bodies 10 may not meet the above requirements. For example, other warehouse bodies 10 may be the size of a standard container.

[0248] In some embodiments, each of the multiple warehouse bodies 10 accommodates multiple energy units 2, and the size of each warehouse body 10 along the first direction is greater than or equal to half the size of a standard container along the first direction, and is smaller than the size of a standard container along the first direction.

[0249] In some embodiments, there are m warehouse bodies 10, the sum of the dimensions of m1 warehouse bodies 10 along the first direction among the m warehouse bodies 10 is smaller than the sum of the dimensions of n standard containers along the first direction, the sum of the dimensions of m1+1 warehouse bodies 10 along the first direction among the m warehouse bodies 10 is greater than the sum of the dimensions of n standard containers along the first direction, m is greater than m1, m is greater than or equal to 2, and m1 is greater than or equal to n.

[0250] Here, by setting the sum of the dimensions of m1 warehouse bodies 10 along the first direction to be smaller than the sum of the dimensions of n standard containers along the first direction, and m1 is greater than or equal to n, that is, the dimension of each warehouse body 10 along the first direction is smaller than the dimension of a standard container along the first direction.

[0251] The m1+1 bins 10 among the m bins 10 refer to any m1+1 bins 10 among the m bins 10. For example, the energy storage device 100 has three bins 10, namely the first bin 3, the second bin 4, and the third bin 10. If m1+1 equals 2, the two bins 10 can be the first bin 3 and the third bin 10, the first bin 3 and the second bin 4, or the second bin 4 and the third bin 10.

[0252] It is possible that m1+1 is less than m, the sum of the dimensions of m1 of the m warehouse bodies 10 along the first direction is less than the sum of the dimensions of n standard containers along the first direction, and the sum of the dimensions of m1+1 of the m warehouse bodies 10 along the first direction is greater than the sum of the dimensions of n standard containers along the first direction. For example, m is 8, m1+1 is 5, and n is 3; the five warehouse bodies 10 can be any five of the eight warehouse bodies 10.

[0253] Alternatively, m1+1 equals m, where the sum of the dimensions of m1 of the m warehouse bodies 10 along the first direction is less than the sum of the dimensions of n standard containers along the first direction, and the sum of the dimensions of m1+1 of the m warehouse bodies 10 along the first direction is greater than the sum of the dimensions of n standard containers along the first direction. For example, if m equals 2, the sum of the heights of two warehouse bodies 10 is greater than the height of one standard container.

[0254] It can be understood that m, m1, and n are all positive integers.

[0255] In some embodiments, m1=1, n=1.

[0256] The energy storage device 100 may include more than two storage bodies 10 , for example, the energy storage device 100 may include 3, 5, or 8 storage bodies 10 . Alternatively, the energy storage device 100 may include only two storage bodies 10 .

[0257] By setting the height of at least one silo 10 to be less than the height of a standard container, and the sum of the heights of the two stacked silos 10 to be greater than the height of a standard container, the reduced size of the silo 10 can reduce the total weight of the silo 10 containing components such as the energy unit 2, thereby alleviating the problem of overweight during transportation and reducing the transportation cost of the energy storage device 100. Furthermore, setting the sum of the dimensions of the two silo 10 along the first direction to be greater than the sum of the dimensions of a standard container along the first direction means that the dimensions of at least one silo 10 along the first direction are maximized, thereby maximizing the power capacity of the energy storage device 100 while still meeting the transportation weight. Furthermore, this also helps to increase the volume and power capacity of the energy storage device 100, further reducing the cost of using the energy storage device 100.

[0258] In some embodiments, m1=2, n=1.

[0259] By setting the height of at least one silo 10 to be less than that of a standard container, and the sum of the heights of the three stacked silos 10 to be greater than that of a standard container, the energy storage device 100 improves manufacturability, achieves a high volumetric energy density, and facilitates transportation and installation by reducing the size of at least one silo 10. Furthermore, by setting the sum of the dimensions of the three silos 10 along the first direction to be greater than the sum of the dimensions of a standard container along the first direction, the energy storage device 100 can maximize its capacity while meeting the transport weight requirement. This also helps increase the volume and capacity of the energy storage device 100, further reducing its operating costs.

[0260] In some embodiments, m1=2, n=2.

[0261] By setting the height of at least one silo 10 to be less than the height of two standard containers, and the sum of the heights of the three silos 10 when stacked to be greater than the sum of the heights of two standard containers, the energy storage device 100, by reducing the size of at least one silo 10, has improved manufacturability, a high volumetric energy density, and is more convenient to transport and install. Furthermore, by setting the sum of the dimensions of the three silos 10 along the first direction to be greater than the sum of the dimensions of a standard container along the first direction, the energy storage device 100 can maximize its capacity while meeting the transport weight. This also helps increase the volume and capacity of the energy storage device 100, further reducing its operating cost.

[0262] Here, the m warehouse bodies 10 may have the same dimensions along the height direction, or the m warehouse bodies 10 may have different dimensions along the height direction.

[0263] In some embodiments, referring to Figures 6 to 13 , the energy storage device 100 further includes a connecting mechanism (not shown), which is configured to connect two adjacent silos 10 along the height direction of the silos 10. The connecting mechanism includes a support member 43, which is disposed between two adjacent silos 10 along the height direction; the sum of the dimensions of m1 silos 10 along the height direction among the m silos 10 and the sum of the dimensions of m1-1 support members 43 along the height direction is less than the sum of the dimensions of n standard containers along the height direction, and the sum of the dimensions of m1+1 silos 10 along the height direction among the m silos 10 and the sum of the dimensions of m1 support members 43 along the height direction is greater than the sum of the dimensions of n standard containers along the height direction.

[0264] Alternatively, if the warehouse bodies 10 assembled for transportation are connected and secured together along the height direction via supports 43, then the dimensions of the m1 warehouse bodies 10 constituting n standard containers also include the height dimensions of the supports 43 between them. In other words, when supports 43 are provided, the height dimensions of some of the m1 warehouse bodies 10 along the height direction may be the sum of their own height and the height of the supports 43 connected to them. This is because the supports 43 connecting the warehouse bodies 10 along the height direction also contribute to a certain degree of the height dimension of the warehouse bodies 10.

[0265] For example, when m1 warehouse bodies 10 are assembled and fixed for transportation using supports 43, the sum of the height dimensions of the m1 warehouse bodies 10 and the sum of the height dimensions of the m1-1 supports 43 is less than the sum of the height dimensions of n standard containers. The sum of the height dimensions of the m1+1 warehouse bodies 10 and the sum of the height dimensions of the m1 supports 43 is greater than the sum of the height dimensions of n standard containers. Optionally, the number of supports 43 between the m1 warehouse bodies 10 can be less than m1-1. In this case, when these warehouse bodies 10 are assembled to the standard container size, the sum of the dimensions of the m1 warehouse bodies 10 and the actual dimensions of the supports 43 are included.

[0266] Connecting the silos 10 via a connecting mechanism makes stacking the silos 10 more stable. When the silos 10 are being transported, the sum of the height dimensions of m1 silos 10 plus the sum of the height dimensions of the support members 43 disposed between two adjacent silos 10 in the m1 silo 10 is less than the sum of the heights of n standard containers. The sum of the height dimensions of m1+1 silos 10 in the m silo 10 plus the sum of the height dimensions of m1 support members 43 is greater than the sum of the height dimensions of n standard containers. This helps increase the volume and power capacity of the energy storage device 100, further reducing the cost of using the energy storage device 100.

[0267] In the energy storage device 100 of the embodiment of the present disclosure, when supports 43 are used during transportation, but supports 43 are not required between the warehouse bodies 10 constituting the energy storage device 100, "the sum of the dimensions of the m1 warehouse bodies 10 in the height direction is less than the sum of the dimensions of the n standard containers in the height direction, and the sum of the dimensions of the m1+1 warehouse bodies 10 in the height direction is greater than the sum of the dimensions of the n standard containers in the first direction" should be understood to include the height of the used supports 43. In other words, the sum of the dimensions of the m1 warehouse bodies 10 in the height direction is less than the sum of the dimensions of the n standard containers in the height direction minus the sum of the heights of the used supports 43, and the sum of the dimensions of the m1+1 warehouse bodies 10 in the height direction is greater than the sum of the dimensions of the n standard containers in the height direction minus the sum of the heights of the used supports 43. Such a situation also falls within the scope of the embodiment of the present disclosure.

[0268] In some embodiments, referring to Figures 3 to 13, the first direction is the height direction of the warehouse body 10, the size of the warehouse body 10 along its length direction is consistent with the size of the length direction of a standard container, and the size of the warehouse body 10 along its width direction is consistent with the size of the width direction of a standard container.

[0269] In this embodiment, by setting the dimensions of the warehouse body 10 along its length direction to be consistent with the dimensions of the length direction of a standard container, and setting the dimensions of the warehouse body 10 along its width direction to be consistent with the dimensions of the width direction of a standard container, it is convenient to match the transportation tools and slings of existing standard containers, thereby reducing the transportation cost of the energy storage device 100 and thus reducing the use cost of the energy storage device 100.

[0270] By setting the height of the silo 10 to be smaller than that of a standard container, the silo 10 does not exceed the height of a standard container for sea or land transport during transportation, thereby improving the convenience of transporting the silo 10 and reducing transportation costs. The length and width of the silo 10 are both consistent with those of a standard container, ensuring that the horizontal area occupied by the silo 10 during transportation is consistent with that of a standard container. This facilitates compatibility with existing standard container transport vehicles and spreaders, reduces the transportation cost of the energy storage device 100, and thus reduces the cost of using the energy storage device 100.

[0271] At the same time, the sum of the dimensions of m1 of the m silos 10 along the first direction is less than the sum of the dimensions of n standard containers along the first direction, and the sum of the dimensions of m1+1 of the m silos 10 along the first direction is greater than the sum of the dimensions of n standard containers along the first direction. This helps increase the volume and power capacity of the energy storage device 100, further reducing the cost of using the energy storage device 100. By reducing the size of the silo 10, the total weight of the silo 10 containing components such as the energy unit 2 can be reduced, which helps alleviate the problem of overweight transportation and reduces the transportation cost of the energy storage device 100. Furthermore, the sum of the dimensions of m1+1 of the m silo 10 along the first direction is greater than the sum of the dimensions of n standard containers along the first direction. This means that by making the dimensions of at least one silo 10 along the first direction as large as possible, the power capacity of the energy storage device 100 can be maximized while meeting the transportation weight. This also helps increase the volume and power capacity of the energy storage device 100, further reducing the cost of using the energy storage device 100.

[0272] In some embodiments, the energy storage device includes an energy storage cabinet 100a, which includes a storage body and components disposed within the storage body. The weight of the energy storage cabinet 100a is M, and M is less than or equal to 35 tons.

[0273] The components disposed in the warehouse body 10 include, for example, the energy unit 2 , connecting pipelines, the control module 30 or the thermal management module 20 .

[0274] Here, the energy storage cabinet 100a refers to a cabinet body that can be transported and hoisted independently.

[0275] For example, the weight of the energy storage cabinet 100 a may be any one of 10 tons, 15 tons, 20 tons, 25 tons, 30 tons, and 35 tons, or any value between any two of them.

[0276] During the process of hoisting the energy storage cabinet 100a, it is convenient to hoist the relevant hoisting devices and to transport the energy storage cabinet 100a.

[0277] To ensure that a single energy storage cabinet 100a meets the transportation limit requirements of some countries, the overall weight of the energy storage cabinet 100a is controlled within 35 tons, and the integration of the energy storage cabinet 100a is as high as possible to reduce the workload of on-site installation; at the same time, the energy per unit area is increased, reducing customer costs.

[0278] In this embodiment, by setting the sum of the dimensions of m1 warehouse bodies 10 along the first direction to be smaller than the sum of the dimensions of n standard containers along the first direction, setting the sum of the dimensions of m1+1 warehouse bodies 10 along the first direction to be larger than the sum of the dimensions of n standard containers along the first direction, and controlling the weight of the energy storage cabinet 100a to be within 35 tons, the energy storage cabinet 100a can be properly transported and hoisted in multiple transportation scenarios, such as land and sea transportation. To a certain extent, this can avoid the problem of the energy storage cabinet 100a being overweight, which would cause the transportation to exceed the load limits of roads, bridges, hoists, etc., and thus require the energy storage cabinet 100a to be disassembled for transportation or require specialized equipment for transshipment, thereby increasing transportation costs.

[0279] In some embodiments, referring to FIG. 3 , the first direction is the height direction of the silo body 10 , the height dimension of the silo body 10 is h, and 850 mm ≤ h < 2896 mm.

[0280] Exemplarily, the height dimension of the warehouse body 10 can be any one of 850mm, 900mm, 950mm, 1000mm, 1050mm, 1100mm, 1150mm, 1200mm, 1300mm, 1400mm, 1500mm, 1600mm, 1800mm, 2000mm, 2100mm, 2200mm, 2300mm, 2400mm, 2500mm, 2600mm, 2700mm, 2800mm, and 2895mm, or a point value between any two of them, and it is necessary to satisfy that the sum of the dimensions of m1 warehouse bodies 10 along the first direction is less than the sum of the dimensions of n standard containers along the first direction, and the sum of the dimensions of m1+1 warehouse bodies 10 among the m warehouse bodies 10 along the first direction is greater than the sum of the dimensions of n standard containers along the first direction.

[0281] In this embodiment, by setting the height of the silo 10 to 850 mm ≤ h < 2896 mm, the total weight of the silo 10 and its internal components can be controlled within 35 tons, and the volume and power of the energy storage device 100 can be increased as much as possible, further reducing the use cost of the energy storage device 100.

[0282] In some embodiments, the first direction is the height direction of the silo body 10 , and the height dimension of the silo body 10 is h, 1300 mm≤h≤2400 mm.

[0283] Exemplarily, the height dimension of the warehouse body 10 can be any one of 1300mm, 1350mm, 1400mm, 1450mm, 1500mm, 1550mm, 1600mm, 1650mm, 1700mm, 1750mm, 1800mm, 1850mm, 1900mm, 1950mm, 2000mm, 2050mm, 2100mm, 2150mm, 2200mm, 2250mm, 2300mm, 2350mm, and 2400mm, or a point value between any two of them, and it is necessary to satisfy that the sum of the dimensions of m1 warehouse bodies 10 along the first direction is less than the sum of the dimensions of n standard containers along the first direction, and the sum of the dimensions of m1+1 warehouse bodies 10 among the m warehouse bodies 10 along the first direction is greater than the sum of the dimensions of n standard containers along the first direction.

[0284] The energy storage device 100 provided by the embodiment of the present disclosure sets the sum of the dimensions of m1 warehouse bodies 10 along the first direction to be smaller than the sum of the dimensions of n standard containers along the first direction, and m1≥n, that is, the dimension of the warehouse body 10 along the first direction is smaller than the dimension of a standard container along the first direction. On the one hand, by reducing the size of the warehouse body 10, the total weight of the warehouse body 10 and its internal components can be made less than the weight of a standard container, so that it can match standard slings, that is, while ensuring that the weight does not exceed the transportation and road limits, it can also match existing standard container transportation tools, which is conducive to improving the problem of overweight transportation, reducing the transportation cost of the energy storage device 100, and thus reducing the use cost of the energy storage device 100; on the other hand, by setting the sum of the dimensions of m1+1 warehouse bodies 10 along the first direction to be greater than the sum of the dimensions of n standard containers along the first direction, it is conducive to increasing the volume and power of the energy storage device 100, and further reducing the use cost of the energy storage device 100.

[0285] In some embodiments, referring to FIG. 4 , the energy storage device 100 includes a thermal management module 20 , which is used to manage the temperatures of the multiple energy units 2 of the energy storage device 100 .

[0286] In this embodiment, by providing the thermal management module 20 , the thermal management module 20 can manage the temperature of the energy unit 2 and reduce the risk of the temperature of the energy unit 2 being out of control.

[0287] In some embodiments, referring to FIG. 4 , there are m warehouse bodies 10 , each of which contains a plurality of energy units 2 , and the thermal management module 20 is used to manage the temperatures of the plurality of energy units 2 in the m warehouse bodies 10 .

[0288] In other words, the energy storage devices 100 share the thermal management module 20 to form a complete system, which is conducive to saving space.

[0289] In some embodiments, referring to FIG. 4 , there are m warehouse bodies 10 , each of which contains a plurality of energy units 2 , and the control module 30 is used to electrically control the plurality of energy units 2 of the m warehouse bodies 10 .

[0290] In other words, the energy storage devices 100 share the control module 30 to form a complete system, which is conducive to saving space.

[0291] In some embodiments, referring to FIG. 4 , the control module 30 is housed in at least one compartment 10 .

[0292] Here, the control module 30 may be accommodated in part of the warehouse body 10 or in all of the warehouse body 10 .

[0293] In an embodiment where some of the storage bodies 10 house the control modules 30, the storage bodies 10 without the control modules 30 can electrically control the energy units 2 via the control modules 30 in the other storage bodies 10. For example, the energy storage device 100 includes two storage bodies 10, namely a first storage body 3 and a second storage body 4. The first storage body 3 houses the control modules 30, and the second storage body 4 houses the energy units 2. The control module 30 in the first storage body 3 can electrically control the energy units 2 in the second storage body 4.

[0294] All the warehouse bodies 10 contain control modules 30. When multiple energy units 2 are set in the first warehouse body 3 and the second warehouse body 4, the control modules 30 in all the warehouse bodies 10 can work together to electrically control the multiple energy units 2 in the first warehouse body 3 and the second warehouse body 4; the control module 30 in each warehouse body 10 can also act separately, that is, the control module 30 in the first warehouse body 3 electrically controls the multiple energy units 2 in the first warehouse body 3, and the control module 30 in the second warehouse body 4 electrically controls the multiple energy units 2 in the second warehouse body 4.

[0295] In some embodiments, referring to FIG. 4 , the thermal management module 20 is housed in at least one compartment 10 .

[0296] The thermal management module 20 may be a liquid cooling unit, an air conditioner, a ground source cooling device or a sea liquid cooling device.

[0297] Here, part of the warehouse body 10 may house the thermal management module 20 , or all of the warehouse body 10 may house the thermal management module 20 .

[0298] In an embodiment where some of the bins 10 house thermal management modules 20, the bins 10 without thermal management modules 20 can manage the temperature of the energy units 2 via the thermal management modules 20 in other bins 10. For example, the energy storage device 100 includes two bins 10, namely a first bin 3 and a second bin 4. The first bin 3 houses the thermal management module 20, while the second bin 4 does not. The thermal management module 20 in the first bin 3 can manage the temperature of the energy units 2 in both the first bin 3 and the second bin 4.

[0299] All the warehouse bodies 10 contain thermal management modules 20. When multiple energy units 2 are set in the first warehouse body 3 and the second warehouse body 4, the thermal management modules 20 in all the warehouse bodies 10 can work together to control the temperature of the multiple energy units 2 in the first warehouse body 3 and the second warehouse body 4; the thermal management module 20 in each warehouse body 10 can also act separately, that is, the thermal management module 20 in the first warehouse body 3 controls the temperature of the multiple energy units 2 in the first warehouse body 3, and the thermal management module 20 in the second warehouse body 4 controls the temperature of the multiple energy units 2 in the second warehouse body 4.

[0300] As an example, when the control module 30 and the thermal management module 20 in the first bin body 3 and the second bin body 4 can operate independently, the first bin body 3 and its internal components can be considered as an independent energy storage device 100; the second bin body 4 and its internal components can be considered as an independent energy storage device 100. As an example, when the control module 30 and the thermal management module 20 in the first bin body 3 and the second bin body 4 need to jointly control the energy units in the two bins, the first bin body 3 and its internal components, the second bin body 4 and its internal components can be considered to jointly form an energy storage device 100. Of course, at this time, only some of the energy units 2 can also be operated. For example, only the energy units 2 in the first bin body 3 are electrically controlled and temperature controlled, so that the energy units 2 in the first bin body 3 input or output electrical energy, and the energy units 2 in the second bin body 4 do not output electrical energy. This can be determined based on actual usage requirements.

[0301] Due to the size of the energy unit 2, there is a situation where the energy unit 2 cannot fill the warehouse body 10. By setting the control module 30 and / or the thermal management module 20 in the warehouse body 10, the space in the warehouse body 10 can be fully utilized, further improving the space utilization rate of the warehouse body 10.

[0302] In addition, the control module 30 and / or the thermal management module 20 are installed together with the warehouse body 10, and the pipes and lines of the control module 30 and / or the thermal management module 20 are connected when shipped, which reduces the installation workload of the pipes and lines of the control module 30 and / or the thermal management module 20 on site, and helps to reduce installation costs.

[0303] Of course, in other embodiments, the control module 30 and / or the thermal management module 20 may also be disposed outside the warehouse body 10 .

[0304] Exemplarily, at least part of the control module 30 is disposed outside the warehouse body 10 .

[0305] That is to say, part of the control modules 30 may be arranged outside the warehouse body 10 , and part of the control modules 30 may be arranged inside the warehouse body 10 ; or all of the control modules 30 may be arranged outside the warehouse body 10 .

[0306] Here, by arranging at least part of the control module 30 outside the warehouse body 10, the influence of the control module 30 on the energy unit 2 can be reduced to a certain extent, and the control module 30 does not occupy the space in the warehouse body 10. In addition, it is also convenient to repair and replace the control module 30.

[0307] Here, the control module 30 disposed outside the warehouse body 10 can be connected to at least one warehouse body 10, or the control module 30 disposed outside the warehouse body 10 is separated from the warehouse body 10, and the two are connected through a connecting line or a connecting pipe.

[0308] Exemplarily, at least part of the thermal management module 20 is disposed outside the warehouse body 10 .

[0309] That is to say, part of the thermal management modules 20 may be arranged outside the warehouse body 10 , and part of the thermal management modules 20 may be arranged inside the warehouse body 10 ; or all of the thermal management modules 20 may be arranged outside the warehouse body 10 .

[0310] Here, by disposing at least part of the thermal management module 20 outside the warehouse body 10, the impact of the thermal management module 20 on the energy unit 2 can be reduced to a certain extent, and the thermal management module 20 does not occupy space in the warehouse body 10. In addition, it is also convenient to repair and replace the thermal management module 20.

[0311] Here, the thermal management module 20 disposed outside the warehouse body 10 can be connected to at least one warehouse body 10, or the thermal management module 20 disposed outside the warehouse body 10 can be separated from the warehouse body 10 and connected by a connecting line or connecting pipe.

[0312] Of course, part of the structure of the thermal management module 20 may be disposed outside the warehouse body 10 , and another part of the structure may be disposed inside the warehouse body 10 .

[0313] For example, the thermal management module 20 includes a cooling fan, which is disposed outside the housing 10 . Alternatively, the thermal management module 20 includes a cooling fan and a heat exchanger, which are disposed outside the housing 10 .

[0314] This is beneficial for the cooling fan, the cooling fan and the heat exchanger to exchange heat with the outside world, thereby improving the heat exchange efficiency.

[0315] In some embodiments, the energy storage device 100 may not include the thermal management module 20 .

[0316] In some embodiments, referring to FIG. 14 , the control module 30 includes at least one of a main control module 301 , a power distribution module 302 , a general control module 303 , and a fire control module 304 .

[0317] The energy unit 2 is electrically connected to the main control module 301. The main control module 301 is electrically connected to the master control module 303. The main control module 301, the master control module 303, and the fire control module 304 are all electrically connected to the power distribution module 302.

[0318] The main control module 301 is used to control the input and output of high voltage electric energy of the energy unit 2 in the warehouse body 10. The master control module 303 is used to control the switching action of the main control module 301 in the warehouse body 10.

[0319] The fire control module 304 is used to control the operation of fire protection components when a fire occurs due to temperature imbalance in the warehouse body 10 . The fire protection components may be fire extinguishers, etc. The fire protection components may be arranged in the warehouse body 10 .

[0320] The power distribution module 302 is used to electrically connect the main control module 301, the general control module 303 and the fire control module 304, so as to facilitate the circuit conduction of the main control module 301, the general control module 303 and the fire control module 304 and maintain the normal operation of the main control module 301, the general control module 303 and the fire control module 304.

[0321] Here, in the embodiment where the energy storage device 100 includes a plurality of control modules 30 , the plurality of control modules 30 may be the same or different.

[0322] Exemplarily, each warehouse body 10 is provided with a control module 30, that is, the control module 30 corresponds one-to-one to the warehouse body 10, and one control module 30 controls the input and output of electrical energy of the energy unit 2 in one warehouse body 10. This is conducive to the control module 30 to electrically control the energy unit 2.

[0323] For example, referring to Figures 6 to 13 , some of the warehouse bodies 10 are provided with the control module 30, while other warehouse bodies 10 are not provided with the control module 30. In other words, one control module 30 controls the power input or output of the energy units 2 in multiple warehouse bodies 10. For example, when there are two warehouse bodies 10, one of the warehouse bodies 10 is provided with the control module 30, while the other warehouse body 10 is not provided with the control module 30. The control module 30 controls the power input or output of the energy units 2 in both warehouse bodies 10.

[0324] Of course, a warehouse body 10 may have multiple control modules 30, and a warehouse body 10 may contain multiple energy units 2. Multiple energy units 2 are connected in series to form a battery cluster, and multiple battery clusters are connected in parallel. One control module 30 can control one or more battery clusters accordingly.

[0325] The thermal management module 20 includes a heat exchange unit, which is, for example, a liquid cooling unit. Please refer to Figure 4. The thermal management module 20 can exchange heat with the energy unit 2 through a heat exchange pipeline 40 (for example, a liquid cooling pipeline 90), thereby achieving temperature management of the energy unit 2 and reducing the risk of temperature out of control of the energy unit 2.

[0326] Exemplarily, each warehouse body 10 is provided with a thermal management module 20 , that is, the thermal management module 20 corresponds to the warehouse body 10 one by one, and one thermal management module 20 manages the temperature of the energy unit 2 in one warehouse body 10 .

[0327] For example, referring to Figures 6 to 13 , some of the warehouse bodies 10 are provided with the thermal management module 20, while other warehouse bodies 10 are not provided with the thermal management module 20. In other words, one thermal management module 20 is responsible for managing the temperatures of the energy units 2 in multiple warehouse bodies 10. For example, when there are two warehouse bodies 10, one of the warehouse bodies 10 is provided with the thermal management module 20, while the other warehouse body 10 is not provided with the thermal management module 20. The thermal management module 20 can exchange heat with the energy units 2 in both warehouse bodies 10 via the heat exchange pipeline 40 (e.g., the liquid cooling pipeline 90). In other words, the thermal management module 20 can manage the temperatures of the energy units 2 in both warehouse bodies 10.

[0328] In some embodiments, the size of the chamber 10 containing the thermal management module 20 along the first direction is larger than the size of other chambers 10 along the first direction.

[0329] This helps increase the space within the housing 10 that houses the thermal management module 20, thereby reducing the impact of the thermal management module 20 on the storage volume of the energy unit 2. This means that the housing 10 has sufficient space to accommodate both the energy unit 2 and the thermal management module 20. Furthermore, a thermal management module 20 with higher cooling capacity can be placed, improving thermal management capabilities.

[0330] Please refer to FIG. 4 . An embodiment of the present disclosure provides a warehouse body 10 , which includes a warehouse body 10 and an energy unit 2 . There are multiple energy units 2 , and the multiple energy units 2 are accommodated in the warehouse body 10 .

[0331] Exemplarily, the housing 10 can be used to accommodate at least one of the control module 30 and the thermal management module 20 .

[0332] In some embodiments, referring to Figures 3 to 13 , at least a portion of the compartment body 10 includes an energy compartment 11 and a control compartment 12. The energy compartment 11 is used to accommodate at least one energy unit 2, and at least a portion of the control module 30 and / or at least a portion of the thermal management module 20 is accommodated in the control compartment 12.

[0333] Here, at least part of the control module 30 and / or at least part of the thermal management module 20 is accommodated in the control compartment 12, which means that at least part of the control module 30 can be accommodated in the control compartment 12, at least part of the thermal management module 20 can be accommodated in the control compartment 12, or at least part of the control module 30 and at least part of the thermal management module 20 can be accommodated in the control compartment 12.

[0334] For example, part of the control module 30 and / or part of the thermal management module 20 may be accommodated in the control compartment 12 inside the warehouse body 10, and another part of the control module 30 and / or another part of the thermal management module 20 may be arranged outside the warehouse body 10; or all of the control modules 30 and / or all of the thermal management modules 20 may be accommodated in the control compartment 12 inside the warehouse body 10.

[0335] For example, in an embodiment where a plurality of warehouse bodies 10 have control warehouses 12 therein, the control modules 30 in all warehouse bodies 10 may act together, or the control module 30 in each warehouse body 10 may act independently.

[0336] For example, in an embodiment where multiple warehouse bodies 10 have thermal management modules 20 inside, the thermal management modules 20 in all warehouse bodies 10 may act together, or the thermal management module 20 in each warehouse body 10 may act independently.

[0337] In this embodiment, by arranging an energy chamber 11 and a control chamber 12 inside at least a portion of the warehouse body 10, and arranging at least a portion of the control module 30 and / or at least a portion of the thermal management module 20 inside the warehouse body 10, the space inside the warehouse body 10 can be fully utilized, thereby further improving the space utilization rate of the warehouse body 10.

[0338] In some embodiments, at least a portion of the chamber body 10 includes a first partition 101 , which is disposed between the energy chamber 11 and the control chamber 12 , and the energy chamber 11 and the control chamber 12 share the first partition 101 .

[0339] Here, the first separator 101 may include a metal plate.

[0340] Here, the first partition 101 is beneficial to improving the structural strength of the warehouse body 10 and is also beneficial to improving the sealing performance and thermal insulation performance of the energy warehouse 11.

[0341] A heat exchange pipeline 40 and a connecting harness 50 are provided on the first partition 101. The connecting harness 50 includes a high-voltage harness 51 and / or a low-voltage harness 52. The thermal management module 20 in the control compartment 12 can exchange heat with the energy unit 2 in the energy compartment 11 through the heat exchange pipeline 40 (for example, a liquid cooling pipeline 90). The control module 30 in the control compartment 12 can electrically control the energy unit 2 in the energy compartment 11 through the connecting harness 50.

[0342] As an example, when the heat exchange pipe 40 and the connecting harness 50 pass through the first partition 101 , the passing position may be sealed.

[0343] Exemplarily, the interior of the first partition 101 is filled with a heat insulating medium.

[0344] Here, the heat insulating medium may be some heat insulating material, such as heat insulating cotton.

[0345] The heat-insulating medium is beneficial to improving the structural strength of the first partition 101 and can also play a flame retardant and heat-insulating effect, which is beneficial to reducing the heat loss of the energy bin and the impact of external heat on the energy units in the energy bin.

[0346] Here, in some embodiments, the warehouse body 10 includes multiple control warehouses 12, and the control warehouses 12 may accommodate the control module 30 and the thermal management module 20, or all the control warehouses 12 may accommodate the control module 30, or all the control warehouses 12 may accommodate the thermal management module 20.

[0347] In some embodiments, there are multiple control compartments 12 , and the first partition 101 can also be set between adjacent control compartments 12 , and the adjacent control compartments 12 share the first partition 101 .

[0348] Illustratively, the first separator 101 separates the thermal management module 20 and the control module 30 , reducing the risk of interference between the thermal management module 20 and the control module 30 , thereby improving the reliability of the energy storage device 100 .

[0349] The thermal management module 20 and the control module 30 are separated by a first partition 101. The first partition 101 can separate the thermal management module 20 and the control module 30, which can reduce the interference of the thermal management module 20 on the control module 30, that is, it can reduce the electromagnetic interference of high-voltage lines on low-voltage lines, and can also reduce the impact of external rainfall or sunlight exposure on the control module 30.

[0350] There are many ways to arrange the energy compartment 11 and the control compartment 12.

[0351] In some embodiments, at least part of the control chamber 12 and the energy chamber 11 are arranged along the height direction of the chamber body 10 .

[0352] Here, part of the control compartment 12 and the energy compartment 11 may be arranged along the height direction of the compartment body 10 , or all of the control compartment 12 and the energy compartment 11 may be arranged along the height direction of the compartment body 10 .

[0353] As an example, the control chamber 12 is arranged above the energy chamber 11 , so that the components in the control chamber can block the heat radiation from the top and reduce the impact of the heat radiation on the interior of the energy chamber 11 .

[0354] Exemplarily, at least part of the control compartment 12 and the energy compartment 11 are arranged along the length direction of the compartment body 10 .

[0355] Here, some of the control compartments 12 and the energy compartments 11 may be arranged along the length direction of the compartment body 10 , or all of the control compartments 12 and the energy compartments 11 may be arranged along the length direction of the compartment body 10 .

[0356] Here, by arranging the control chamber 12 at the end of the chamber body 10, the space utilization inside the chamber body 10 is maximized. In addition, the control chamber 12 and the energy chamber 11 can be arranged closer, which is conducive to improving the compactness of the structure.

[0357] In some embodiments, referring to FIG. 3 and FIG. 4 , at least a portion of the control compartment 12 accommodates a thermal management module 20 , and the thermal management module 20 is located on the top of the topmost compartment body 10 .

[0358] In this embodiment, the thermal management module 20 is located at the top of the topmost bin body 10. There is no obstruction above the thermal management module 20, which facilitates heat dissipation from the thermal management module 20, thereby increasing the service life of the energy storage device 100. This also helps lower the overall center of gravity height of a single bin body 10, which is beneficial for transportation safety. Furthermore, the design of a separate bin from the energy bin 11 helps improve the thermal insulation of the energy bin 11. At the same time, the thermal management module 20 blocks thermal radiation from the top, reducing the impact of thermal radiation on the interior of the energy bin 11.

[0359] 6 and 7 , at least a portion of the control compartment 12 contains a control module 30 . The control module 30 and the energy compartment 11 are arranged along the height direction of the compartment body 10 .

[0360] That is to say, the control module 30 can be located above the energy bin 11 , below the energy bin 11 , or in the middle of the two energy bins 11 in the height direction.

[0361] For example, when there are two warehouse bodies 10, the control module 30 is arranged on the top of the lower warehouse body 10, that is, above the energy warehouse 11 of the lower warehouse body 10. The height of the operating part meets the requirements of ergonomics. The maintenance personnel can reach the operating handle of the control part by standing on one side of the warehouse body 10, which is convenient for maintenance and inspection. At the same time, the control warehouse 12 at the top is conducive to shortening the length of the high-voltage wire harness 51 and the low-voltage wire harness 52 connecting with the upper warehouse body 10, thereby reducing costs.

[0362] 8 and 9 , at least a portion of the control compartment 12 contains a control module 30 . The control module 30 and the energy compartment 11 are arranged along the length of the compartment body 10 .

[0363] That is to say, the control module 30 can be located at the left end of the energy bin 11 , or at the right end of the energy bin 11 , or in the middle of the two energy bins 11 along the length direction.

[0364] In some embodiments, referring to FIG. 3 to FIG. 13 , the energy storage device 100 includes a pipeline compartment 13 , which is used to accommodate at least a portion of connecting pipelines between the control module 30 , the thermal management module 20 , and the energy unit 2 .

[0365] Illustratively, the connecting pipelines may be a liquid cooling pipeline 90 , a high-voltage wiring harness 51 , a low-voltage wiring harness 52 , a firefighting pipeline, a water firefighting pipeline, and the like.

[0366] The pipeline bin 13 is at least used to accommodate at least part of the connecting pipelines between the control module 30, the thermal management module 20 and the energy unit 2. That is, the connecting pipes and / or connecting lines between the control module 30, the thermal management module 20 and the energy unit 2 can be partially passed through the pipeline bin 13, or can be completely passed through the pipeline bin 13.

[0367] Of course, the pipeline compartment 13 can also be used to accommodate other components of the energy storage device 100, such as a fire control module.

[0368] For example, the high-voltage wiring harness 51 and the low-voltage wiring harness 52 connecting the pipeline compartment 13 to the energy compartment 11 and the control compartment 12 are connected by connectors installed on the partition wall; the pipeline connection between the pipeline compartment 13 and the energy compartment 11 is connected through a liquid-cooled adapter; and the wall-penetrating interfaces are all sealed.

[0369] In this embodiment, the energy storage device 100 is provided with a pipeline warehouse 13, which is used to accommodate at least part of the connecting pipelines between the control module 30, the thermal management module 20 and the energy unit 2, which is convenient for wiring and piping, and is conducive to making the layout of the connecting pipelines reasonable and easy to repair and replace.

[0370] In some embodiments, please refer to Figures 6 to 9. Each warehouse body 10 is provided with a pipeline warehouse 13, that is, one warehouse body 10 is provided with one pipeline warehouse 13. Of course, one warehouse body 10 can also be provided with multiple pipeline warehouses 13. At least part of the connecting pipelines between the control module 30, the thermal management module 20 and the energy unit 2 in one warehouse body 10 can be accommodated in the corresponding pipeline warehouse 13. This is beneficial for wiring and piping, and is conducive to making the layout of the connecting pipelines reasonable, which is convenient for maintenance and replacement.

[0371] In some embodiments, part of the warehouse body 10 is provided with a pipeline warehouse 13 , while another part of the warehouse body 10 is not provided with a pipeline warehouse 13 .

[0372] Some of the silos 10 are provided with pipeline compartments 13, while other silos 10 are not provided with pipeline compartments 13. In other words, one pipeline compartment 13 is used to accommodate at least a portion of the connecting pipelines between the control modules 30, thermal management modules 20, and energy units 2 of the multiple silos 10. For example, when there are two silos 10, one of the silos 10 is provided with a pipeline compartment 13, while the other silo 10 is not provided with a pipeline compartment 13. The pipeline compartment 13 is used to accommodate at least a portion of the connecting pipelines between the control modules 30, thermal management modules 20, and energy units 2 of the two silos 10.

[0373] In some embodiments, referring to Figures 10 to 13, at least part of the warehouse body 10 has an energy warehouse 11 and a control warehouse 12 inside, the energy warehouse 11 is used to accommodate at least one energy unit 2, at least part of the control module 30 and / or at least part of the thermal management module 20 is accommodated in the control warehouse 12, the pipeline warehouse 13 is arranged inside the warehouse body 10, and the pipeline warehouse 13 and the energy warehouse 11 are arranged along the length direction of the warehouse body 10.

[0374] That is to say, the pipeline bin 13 can be at the left end of the energy bin 11 , or at the right end of the energy bin 11 , or in the middle of the two energy bins 11 along the length direction.

[0375] Of course, in the embodiment with the control chamber 12 , the pipeline chamber 13 and the energy chamber 11 may be arranged along the length direction of the chamber body 10 or along the height direction of the chamber body 10 .

[0376] In other embodiments, referring to FIG. 16 , the pipeline bin 13 is disposed outside the bin body 10 . For example, a protective cover 60 is provided, and the interior of the protective cover 60 has the pipeline bin 13 , or the protective cover 60 and the bin body 10 define the pipeline bin 13 .

[0377] It should be noted that, in the embodiment where the pipeline bin 13 is arranged outside the bin body 10 , the pipeline bin 13 does not belong to the bin body 10 , and thus, the size of the pipeline bin 13 is not counted in the size of the bin body 10 .

[0378] In some embodiments, referring to Figures 6 to 9, at least a portion of the silo body 10 includes a second partition 102, and the second partition 102 is disposed between the energy silo 11 and the pipeline silo 13, and the energy silo 11 and the pipeline silo 13 share the second partition 102.

[0379] Here, the second separator 102 may include a metal plate.

[0380] Here, the second partition 102 is beneficial to improving the structural strength of the warehouse body 10 and is also beneficial to improving the sealing performance and thermal insulation performance of the energy warehouse 11.

[0381] In some embodiments, referring to Figures 9 and 13, at least part of the bin body 10 includes a third partition 103, and the third partition 103 is arranged between the pipeline bin 13 and at least part of the control bin 12, and the pipeline bin 13 and at least part of the control bin 12 share the third partition 103.

[0382] Here, the third spacer 103 may include a metal plate.

[0383] Here, the third partition 103 is beneficial to improving the structural strength of the warehouse body 10 and is also beneficial to improving the sealing performance and thermal insulation performance of the partial control warehouse 12.

[0384] Exemplarily, the control compartment 12 containing the thermal management module 20 may be in communication with the pipeline compartment 13 , so that the energy compartment 11 is connected to the control compartment 12 containing the thermal management module 20 through the pipeline compartment 13 .

[0385] For example, the control compartment 12 accommodating the control module 30 may be isolated from the pipeline compartment 13 .

[0386] In some embodiments, referring to FIG. 4 , the first compartment doors 104 of the energy compartment 11 , the control compartment 12 , and the pipeline compartment 13 are all located at the front side of the compartment body 10 .

[0387] In this embodiment, by arranging the first doors 104 of the energy bin 11, the control bin 12 and the pipeline bin 13 on the front side of the bin body 10, they can be inspected and maintained through their respective first doors 104, thereby reducing the land waste of the traditional bin bodies 10, which requires reserving a maintenance passage of more than 3m between each bin body 10. Only normal paint touch-up maintenance passages need to be reserved between the grid bin bodies 10, which improves the user's land investment income and increases the user's energy income per unit area.

[0388] In some embodiments, please refer to Figure 17, at least part of the warehouse body 10 has an energy warehouse 11 and a control warehouse 12 inside, the energy warehouse 11 is used to accommodate at least one energy unit 2, at least part of the control module 30 and / or at least part of the thermal management module 20 is accommodated in the control warehouse 12; the warehouse body 10 is provided with a first warehouse door 104 on at least one side along the width direction, and the control warehouse 12 and / or the pipeline warehouse 13 are provided with a second warehouse door 70 on at least one side along the width direction.

[0389] Here, the second compartment door 70 may be an inspection door. By providing the inspection door, it is convenient to inspect the energy storage device 100 through the inspection door.

[0390] The energy compartment 11, the control compartment 12 and the pipeline compartment 13 may all be provided with inspection doors.

[0391] In some embodiments, referring to FIG. 17 , a second compartment door 70 is provided on at least one side of the control compartment 12 and / or the pipeline compartment 13 along the width direction.

[0392] That is to say, the warehouse body 10 can be provided with a second warehouse door 70 on at least one side along the width direction, or can be provided with a second warehouse door 70 on both sides along the width direction, so that the warehouse body 10 is provided with a second warehouse door 70 in the area corresponding to at least part of the control warehouse 12 and / or at least part of the pipeline warehouse 13.

[0393] For example, a second compartment door 70 is provided on the right side of the upper compartment body 10, the right side of the control compartment 12, and the right side of the lower compartment body 10. By opening the second compartment door 70, the liquid cooling pipeline 90, the high-voltage wiring harness 51, and the low-voltage wiring harness 52 can be inspected and maintained.

[0394] In this embodiment, it is beneficial to reduce the land waste of traditional warehouse bodies 10 that must reserve maintenance channels of more than 3m between adjacent warehouse bodies 10. Only normal paint repair channels need to be reserved between the grid warehouse bodies 10, which increases the user's land investment returns and increases the user's energy benefits per unit area.

[0395] In some embodiments, referring to Figures 6 to 13, multiple warehouse bodies 10 include a first warehouse body 3 and a second warehouse body 4, the first warehouse body 3 is located above the second warehouse body 4, at least the first warehouse body 3 accommodates multiple energy units 2, the thermal management module 20 is arranged in the first warehouse body 3 and located on top of the multiple energy units 2, and the control module 30 is arranged in the first warehouse body 3 and / or the second warehouse body 4.

[0396] The first storage body 3 and the second storage body 4 are stacked in the height direction, and the first storage body 3 is located above the second storage body 4.

[0397] The control module 30 is arranged in the first warehouse body 3 and / or the second warehouse body 4, which means that the control module 30 can be arranged in the first warehouse body 3, the second warehouse body 4, or both the first warehouse body 3 and the second warehouse body 4.

[0398] The first housing 3 is located above the second housing 4, allowing the thermal management module 20 to be located at the top of the energy storage device 100. This leaves no obstructions above the thermal management module 20, further facilitating heat dissipation from the thermal management module 20. Furthermore, the thermal management module 20 and the control module 30 can be further separated, reducing interference from the thermal management module 20 on the control module 30.

[0399] In this embodiment, by accommodating the thermal management module 20 in the control compartment 12 of the first compartment body 3 located above, and accommodating the control module 30 in the control compartment 12 of the second compartment body 4 located below, the interference of the thermal management module 20 on the control module 30 can be reduced. In addition, the location of the thermal management module 20 in the first compartment body 3 located above is further conducive to the heat dissipation of the thermal management module 20, so that the thermal management module 20 can have more heat dissipation channels, thereby improving the temperature control effect of the thermal management module 20. At the same time, it is conducive to reducing the overall center of gravity height of a single energy storage cabinet 100a, which is beneficial to transportation safety. In addition, the compartment design with the energy compartment 11 is conducive to improving the thermal insulation effect of the energy compartment 11. At the same time, the thermal management module 20 blocks the heat radiation from the top, reducing the impact of heat radiation on the interior of the energy compartment 11.

[0400] In other embodiments, the thermal management module 20 may also be disposed at the bottom of the first storage body 3 ; and / or, at the bottom of the second storage body 4 ; and / or, at the top of the second storage body 4 .

The energy warehouse 11 is connected to the control warehouse 12 accommodating the thermal management module 20 in the upper layer through the pipeline warehouse 13, and is also connected to the warehouse body 10 in the lower layer; wherein the energy warehouse 11 accommodates energy units 2, connecting pipelines between energy units 2, connecting wiring harnesses 50 between energy units 2, liquid cooling main lines 91, fire sensors, etc.; the pipeline warehouse 13 includes liquid cooling pipelines 90 that penetrate the wall, high-voltage wiring harnesses 51, low-voltage wiring harnesses 52, fire pipelines, water fire pipelines, etc.; the control warehouse 12 accommodating the thermal management module 20 includes a liquid cooling unit and its fixing bracket, and the top wall and / or side wall of the control warehouse 12 accommodating the thermal management module 20 are provided with vents, which are used for ventilation of the thermal management module.

[0402] Exemplarily, the second warehouse body 4 includes an energy warehouse 11, a pipeline warehouse 13 and a control warehouse 12 accommodating a control module 30.

[0403] In order to facilitate quick installation at the customer's site, the control module 30 and the thermal management module 20 are integrated inside the warehouse body 10. After the warehouse body 10 is stacked on site, it can be connected to the PCS and EMS, which helps to reduce the workload of on-site assembly, improve assembly efficiency, and facilitate customer use.

[0404] The PCS (Power Conversion System) controls the battery's charging and discharging process, converting AC to DC, and can directly power AC loads in the absence of a power grid. The PCS consists of a DC / AC bidirectional converter and a control unit. The PCS controller receives backend control commands via communication and controls the converter to charge or discharge the battery based on the sign and magnitude of the power command, thereby regulating the grid's active and reactive power. The PCS controller communicates with the BMS via the CAN interface to obtain battery pack status information, enabling protective charging and discharging of the battery.

[0405] An EMS (Energy Management System) is a collection of software and hardware used to monitor, control, analyze, and optimize energy systems. It enables efficient energy management and optimized allocation through real-time monitoring and intelligent control of all aspects of energy production, distribution, and consumption.

Maintenance personnel standing on the side of the silo 10 can easily reach the operating handle of the control unit, facilitating maintenance and inspection. Furthermore, the top location of the control silo 12 helps shorten the length of the high-voltage and low-voltage wiring harnesses 51 and 52 connecting the silo 10 to the upper level, thereby reducing costs. Furthermore, it helps lower the overall center of gravity of a single silo 10, improving transportation safety.

Alternatively, a portion of the top wall of the silo 10 may be open to form a vent 14; for example, an opening may be provided on one side of the top wall of the silo 10 along its length, so that a portion of the top wall of the silo 10 forms the vent 14.

[0412] As an example, the vents 14 on the top wall of the silo body 10 can be used for exhausting air, and the vents 14 on the side walls of the silo body 10 can be used for taking in air.

[0413] In this embodiment, the vents 14 are located on the top wall of the housing 10 , which is beneficial for heat dissipation of the thermal management module 20 , so that the thermal management module 20 can have more heat dissipation channels, thereby improving the temperature control effect of the thermal management module 20 .

The thermal management component 82 can be a part of the box 81 or the thermal management component 82 is located in the accommodating space of the box 81. The thermal management component 82 can also be located between adjacent energy units 2.

[0426] At least part of the warehouse body 10 includes the third connector 8 means that part of the warehouse body 10 may include the third connector 8, and another part of the warehouse body 10 does not have the third connector 8, or all of the warehouse body 10 may include the third connector 8.

[0427] The third connector 8 can be directly connected to the fourth connector 9 to achieve the matching of the third connector 8 and the fourth connector 9. For example, the third connector 8 can be plugged into each of the fourth connectors 9.

[0428] Exemplarily, the third connector 8 is provided at the first partition 101 and / or the third partition 103 of the control compartment 12 .

[0429] Alternatively, the third connector 8 and the fourth connector 9 may be connected via a connector, which may be a pipe.

[0430] As an example, the thermal management module 20 is equipped with a third connector 8, and each housing 10 is equipped with a fourth connector 9. The third connector 8 and the fourth connector 9 are connected by a pipeline. The pipeline can be a quick-connect pipeline with quick-connect fittings at both ends. The first connector 6 and the second connector 7 are also quick-connect fittings. The two quick-connect fittings at both ends of the pipeline are connected to the first connector 6 and the second connector 7 respectively.

[0431] In this embodiment, the third connector 8 and the fourth connector 9 cooperate to achieve rapid connection between the thermal management component 82 and the thermal management module 20 , thereby facilitating the installation of the thermal management module 20 .

[0432] In some embodiments, the thermal management module 20 is connected to multiple thermal management components 82 through a liquid cooling pipeline 90. The liquid cooling pipeline 90 includes a main pipeline 91 and multiple branch pipelines 92. The multiple branch pipelines 92 are connected to the main pipeline 91 in parallel. The main pipeline 91 is connected to the thermal management module 20, and the multiple branch pipelines 92 are respectively connected to the multiple thermal management components 82; the main pipeline 91 is located above the multiple battery devices 80, or the main pipeline 91 is located below the multiple battery devices 80.

[0433] In the embodiment where the main pipe 91 is located above the multiple battery devices 80 , it is beneficial for the liquid cooling medium to flow from top to bottom through the main pipe 91 to the multiple branch pipes 92 to cool the battery devices 80 .

[0434] In the embodiment where the main pipe 91 is located below the plurality of battery devices 80 , it is advantageous for the liquid cooling medium to flow from bottom to top through the main pipe 91 to the plurality of branch pipes 92 to cool the battery devices 80 .

[0435] Exemplarily, the energy storage device 100 includes two warehouse bodies 10, each of which contains an energy unit 2, and the main line 91 is located above the two warehouse bodies 10, or the main line 91 is located below the two warehouse bodies 10, or one of the main lines 91 is located above one of the warehouse bodies 10, and the other main line 91 is located below the other warehouse body 10.

[0436] Here, by arranging the main line 91 above the plurality of battery devices 80 or below the plurality of battery devices 80 , the liquid cooling line 90 can be shortened, thereby reducing costs and improving cooling efficiency.

[0437] In some embodiments, the energy unit 2 is a battery cell, and the weight of a single energy unit 2 is 5 kg to 60 kg.

[0438] The weight of a single energy unit 2 can be any one of 5kg, 10kg, 15kg, 20kg, 25kg, 30kg, 35kg, 40kg, 45kg, 50kg, 55kg, 60kg or any value therebetween. As an example, the mass of a single energy unit 2 is 30kg.

[0439] The weight of the energy unit 2 is appropriate so that an appropriate amount of energy units 2 can be placed in the warehouse 10, and the energy density is moderate while meeting the transportation requirements.

[0440] In some embodiments, the energy storage device 100 includes an energy storage cabinet 100a, which includes a warehouse body 10 and components disposed in the warehouse body 10. The weight of the energy storage cabinet 100a is M, and the total weight of the energy unit 2 in the warehouse body 10 is M1, and (M1 / M)×100%≥60%.

[0441] Exemplarily, (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.

[0442] In this way, on the one hand, the weight proportion of the energy unit 2 in the unit volume of the warehouse body 10 can be increased, and the power of the energy storage device 100 per unit volume can be increased; on the other hand, during the transportation of the energy storage device 100, more energy units 2 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 warehouse body 10 is assembled into the energy storage device 100, it is beneficial to reduce the transportation cost of the assembled energy storage device 100.

[0443] In some embodiments, (M1 / M)×100%≧80%.

[0444] Illustratively, (M1 / M)×100% may be 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89% or 90%, etc.

[0445] This further helps reduce the transportation cost of the assembled energy storage device 100 .

[0446] In some embodiments, the energy storage device 100 includes an energy storage cabinet 100a, which includes a warehouse body 10 and components disposed in the warehouse body 10. The weight of the energy storage cabinet 100a is M. Multiple battery devices 80 are disposed in the warehouse body 10. The battery device 80 includes a box body 81 and multiple energy units 2. The multiple energy units 2 are accommodated in the box body 81. The total weight of the battery device 80 is M2, and 70%≤(M2 / M)×100%≤90%.

[0447] (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.

[0448] When (M2 / M)×100% ≥ 70%, the weight ratio of the energy unit 2 per unit volume of the storage body 10 can be increased, thereby improving the energy density of the storage body 10. When (M2 / M)×100% ≤ 90%, the structural strength of the storage body 10 can be maintained. Therefore, when 70% ≤ (M2 / M)×100% ≤ 90%, both the energy density of the energy storage cabinet 100a and the structural strength of the storage body 10 are achieved, making the storage body 10 more practical.

[0449] In some embodiments, multiple battery devices 80 can be arranged in rows and columns, with the multiple battery devices 80 in each row arranged along the length direction and the multiple battery devices 80 in each column arranged along the height direction. Each battery device 80 includes a thermal management component 82 and multiple energy units 2. The housing 10 also includes a third connector 8 and multiple fourth connectors 9. The third connector 8 connects to the thermal management module 20 and each of the fourth connectors 9. Each of the fourth connectors 9 connects to the thermal management component 82 of the multiple battery devices 80 in a column.

[0450] Illustratively, the plurality of battery devices 80 are arranged in 2 layers and 2 columns, 3 layers and 3 columns, 4 layers and 4 columns, 4 layers and 3 columns, etc.

[0451] It should be noted that the plurality of battery devices 80 may also 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.

[0452] In some embodiments, the volume of the warehouse body 10 is V, the total volume of the energy units 2 in the warehouse body 10 is V1, and (V1 / V)×100%≥30%.

[0453] The energy unit 2 includes a shell, and the volume of the energy unit 2 is the volume of the shell. For example, the energy unit 2 is a square shell energy unit 2, and the product of the length, width and height of the square shell energy unit 2 is the product of the length, width and height of the shell.

[0454] In an embodiment where the energy unit 2 further includes an electrode terminal, the electrode terminal is disposed in the outer shell and partially protrudes from the outer shell. The electrode terminal is electrically connected to the electrode assembly, and the portion of the electrode terminal protruding from the outer shell is not counted as part of the volume of the energy unit 2 .

[0455] (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.

[0456] On the one hand, the volume ratio of the energy unit 2 in the unit volume of the warehouse body 10 can be increased, and the power of the energy storage device 100 per unit volume can be increased; on the other hand, during the transportation of the energy storage device 100, more energy units 2 that contribute to the 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 without having to be transported or with reduced transportation. After the warehouse body 10 is assembled into the energy storage device 100, this is conducive to reducing the transportation cost of the assembled energy storage device 100.

[0457] In some embodiments, (V1 / V)×100%≧50%.

[0458] (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.

[0459] This is further beneficial to reducing the transportation cost of the assembled energy storage device 100 .

[0460] In some embodiments, the volume of the warehouse body 10 is V, and multiple battery devices 80 are arranged in the warehouse body 10. The battery device 80 includes a box body 81 and multiple energy units 2. The multiple energy units 2 are accommodated in the box body 81. The total volume of the battery device 80 is V2, 50%≤(V2 / V)×100%≤80%.

[0461] The volume of the energy unit 2 is the volume of the box 81. For example, if the box 81 is a rectangular parallelepiped structure, the volume of the energy unit 2 is equal to the product of the length, width and height of the box 81.

[0462] (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.

[0463] When (V2 / V)×100%≥50%, the volume ratio of the energy unit 2 per unit volume of the silo 10 can be increased, thereby improving the energy density of the energy storage device 100. When (V2 / V)×100%≤80%, the silo 10 can have sufficient structural components to maintain the structural strength of the silo 10. Therefore, when 50%≤(V2 / V)×100%≤80%, both the energy density of the energy storage device 100 and the structural strength of the silo 10 can be achieved, making the silo 10 more practical.

[0464] In some embodiments, referring to FIG6 , the energy storage device 100 includes an energy storage cabinet 100 a, which includes a housing 10 and components disposed within the housing 10.

[0466] The energy E can be obtained from the nameplate of the energy storage device 100 .

[0467] 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, the energy density of the energy storage device 100 and the mass setting of the warehouse body 10 are taken into consideration, thereby improving the practicality of the energy storage device 100 and facilitating the transportation of the energy storage device 100.

[0468] In some embodiments, 450KW / m 2 ≤E / (a×b)≤600KW / m 2 .

[0469] 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.

[0470] As an example, E / (a×b)=490KW / m 2 The energy density of the energy storage device 100 and the mass setting of the warehouse body 10 can be further improved, making it easier to transport the energy storage device 100 .

[0471] In some embodiments, along the height direction of the bin body 10, two adjacent bin bodies 10 are connected by welding, snapping, locking or by fixing parts.

[0472] The fixing member may be at least one of a bolt and nut, a pin, a screw or a rivet, etc. Of course, the fixing member may also include a fixing plate, etc., to fix and connect two adjacent bin bodies 10 in the height direction.

[0473] Exemplarily, two adjacent bin bodies 10 are connected by an intermediate twist lock.

[0474] Two adjacent bin bodies 10 along the height direction are connected by fixing parts, and the fixing parts can be used to limit the two adjacent bin bodies 10 along the height direction, which is beneficial to reduce the risk of the two adjacent bin bodies 10 moving with each other after stacking is completed, and further beneficial to improve the structural stability of the energy storage device 100.

[0476] The silo 10 includes a first silo 3 and a second silo 4. The same silo 10 is the first silo 3 relative to the silo 10 below, and the second silo 4 relative to the silo 10 above. That is, the same silo 10 can be both the first silo 3 and the second silo 4. In other words, a limit pin 42 can be provided at the bottom of the silo 10, and a limit hole 411 can be provided at the top.

[0477] In this way, the two adjacent bin bodies 10 in the height direction can achieve the purpose of limiting the relative movement of the two adjacent bin bodies 10 by using a simple structure through the cooperation of the limiting pin 42 and the limiting hole 411.

[0478] The limiting hole 411 on the top of the second warehouse body 4 can be an opening for hoisting the warehouse body 10. In this way, during the hoisting stage of the warehouse body 10, the warehouse body 10 is hoisted using the opening. After the hoisting of the warehouse body 10 is completed, the opening on the top of the warehouse body 10 is used to cooperate with the limiting pin 42 at the bottom of the adjacent upper warehouse body 10 to achieve the limitation of the two adjacent warehouse bodies 10. This is conducive to simplifying the structure of the warehouse body 10.

[0479] In some embodiments, referring to Figures 6 to 9 and 15, a first limiting member 31 is provided at the bottom of the first bin body 3, and the first limiting member 31 is provided with a limiting groove 311. A second limiting member 41 is provided at the top of the second bin body 4, and the second limiting member 41 is provided with a limiting hole 411. The two ends of the limiting pin 42 are respectively engaged with the limiting groove 311 and the limiting hole 411.

[0480] The second limiting member 41 may be the aforementioned hoisting portion, and the limiting hole 411 may be the aforementioned opening. The limiting hole 411 may also be a hole provided on the bin body 10 .

[0481] In this embodiment, during the stacking of the bin bodies 10 along the height direction, the limiting pin 42 cooperates with the limiting groove 311 of the upper bin body 10 between the two adjacent bin bodies 10, and cooperates with the limiting hole 411 of the lower bin body 10 between the two adjacent bin bodies 10. In this way, the purpose of limiting the relative movement of the two adjacent bin bodies 10 is achieved through a simple structure.

[0482] In some embodiments, referring to Figures 10 to 13, the first direction is the height direction of the warehouse body 10. Along the height direction of the warehouse body 10, the height of a part of the warehouse bodies 10 among the multiple warehouse bodies 10 is not equal to the height of another part of the warehouse bodies 10.

[0483] For example, the height of the upper warehouse body 10 may be greater than the height of the lower warehouse body 10 , or the height of the upper warehouse body 10 may be less than the height of the lower warehouse body 10 .

[0484] In this way, the flexibility of the capacity of the warehouse body 10 can be improved to meet different needs.

[0485] In some embodiments, the m silo bodies 10 have the same dimensions along the height direction of the silo body 10 .

[0486] This simplifies the manufacturing process and reduces costs.

[0487] The disclosed embodiments further provide an energy storage device 100, comprising a silo 10 and a plurality of energy units 2, wherein the plurality of energy units 2 are housed within the silo 10. The size of the silo 10 along a first direction is greater than one-third the size of a standard container along the first direction, and less than one-half the size of a standard container along the first direction; alternatively, the size of the silo 10 along the first direction is greater than one-half the size of a standard container along the first direction, and less than the size of one standard container along the first direction.

[0488] The compartment 10 contains a plurality of energy units 2, which may be battery modules or battery packs.

[0489] The dimensions of the silo 10 along the first direction are set to be smaller than the dimensions of a standard container along the first direction. By reducing the dimensions of the silo 10, the total weight of the silo 10 containing components such as the energy unit 2 can be reduced, thereby alleviating the problem of overweight during transportation and reducing the transportation cost of the energy storage device 100. The dimensions of the silo 10 cannot be infinitely small. When the dimensions of the silo 10 along the first direction are greater than or equal to one-third the dimensions of a standard container along the first direction, the energy storage device 100 has high manufacturability, high volumetric energy density, and is more convenient to transport and install.

[0490] The embodiment of the present disclosure provides an energy storage device 100, comprising a first warehouse body 3, a second warehouse body 4, a control module 30, a thermal management module 20, and a plurality of energy units 2. The first warehouse body 3 and the second warehouse body 4 each contain a plurality of energy units 2, and the first warehouse body 3 is located above the second warehouse body 4. The dimensions of the first warehouse body 3 and the second warehouse body 4 along the first direction are both greater than or equal to half the dimensions of a standard container along the first direction, and are both smaller than the dimensions of a standard container along the first direction. The sum of the dimensions of the first warehouse body 3 and the second warehouse body 4 along the first direction is greater than the sum of the dimensions of a standard container along the first direction. The first warehouse body 3 comprises an energy warehouse 11 and a control warehouse 12. The control warehouse 12 is disposed above the energy warehouse 11. The thermal management module 20 is disposed in the control warehouse 12 of the first warehouse body 3. The energy warehouse 11 of the first warehouse body 3 contains a plurality of energy units 2. The second compartment 4 includes an energy compartment 11 and a control compartment 12. The control compartment 12 is located above the energy compartment 11. The control module 30 is located within the control compartment 12 of the second compartment 4. The energy compartment 11 of the second compartment 4 houses multiple energy units 2. The thermal management module 20 within the first compartment 3 is capable of temperature-controlling the multiple energy units 2 within the first compartment 3 and the multiple energy units 2 within the second compartment 4. The control module 30 within the second compartment 4 is capable of electrically controlling the multiple energy units 2 within the first compartment 3 and the multiple energy units 2 within the second compartment 4. By splitting the energy storage device 100 into the first compartment 3 and the second compartment 4, all components of the energy storage device 100 are housed within the first compartment 3 and the second compartment 4. This reduces the size of the compartment 10, thereby reducing the total weight of the compartment 10 containing the energy units 2 and other components. This helps alleviate the problem of overweight during transportation and reduces the transportation cost of the energy storage device 100. After the first and second silo bodies 3 and 4 are stacked together along the first direction, the sum of their dimensions along the first direction exceeds the dimensions of a standard container. This maximizes the power capacity of the energy storage device 100 while maintaining the required transport weight. This also helps increase the volume and power capacity of the energy storage device 100, further reducing its operating costs. Furthermore, all components of the energy storage device 100 are integrated within the silo body 10. Once the silo bodies 10 are stacked on-site, connections to the PCS and EMS can be made. This reduces on-site assembly workload, improves assembly efficiency, and facilitates customer use.
