[0010] Wherein, the size of at least one the warehouse body in a plurality of the warehouse body along the first direction is less than the size of one standard container along the first direction, the sum of the size of a plurality of the warehouse body along the first direction is greater than the sum of the size of one or more the standard container along the first direction, the first direction is the length direction, width direction or height direction of the warehouse body.

[0011] The energy storage device provided by the embodiments of the present application can reduce the total weight of the warehouse body and the components in the warehouse body by reducing the size of the warehouse body, which is beneficial to improve the problem of overweight transportation, reduce the transportation cost of the energy storage device, and thus reduce the use cost of the energy storage device. And the sum of the size of a plurality of warehouse bodies along the first direction is greater than the sum of the size of one or more standard containers along the first direction, that is, on the one hand, the sum of the size of a plurality of warehouse bodies along the first direction is greater than the sum of the size of one or more standard containers along the first direction, which means that the size of at least one warehouse body along the first direction is as large as possible, and under the premise of meeting the transportation weight, the power of the energy storage device can be improved as much as possible.

[0112] The two ends of the limiting pin are respectively connected with the limiting slot and the limiting hole to fix the adjacent two bin bodies, and a simple structure is used to limit the relative movement of the adjacent two bin bodies.

[0113] In some embodiments, the plurality of bin bodies includes m bin bodies, the first direction is the height direction of the bin bodies, and the energy storage device further includes a connecting mechanism configured to connect two adjacent bin bodies in the height direction of the bin bodies.

[0114] The connecting mechanism includes a support arranged between the two adjacent bin bodies in the height direction, the sum of the sizes of m1 bin bodies in the m bin bodies in the height direction and the sum of the sizes of m1-1 supports in the height direction is less than the sum of the sizes of n standard containers in the height direction, and the sum of the sizes of m1+1 bin bodies in the m bin bodies in the height direction and the sum of the sizes of m1 supports in the height direction is greater than the sum of the sizes of n standard containers in the height direction.

[0115] The connecting mechanism is used to connect the bin bodies, so that the stacking of the bin bodies is more stable. When the bin bodies are transported, the sum of the sizes of m1 bin bodies in the height direction and the sum of the sizes of supports arranged between the two adjacent bin bodies in the m1 bin bodies in the height direction is less than the sum of the heights of n standard containers, and the sum of the sizes of m1+1 bin bodies in the m bin bodies in the height direction and the sum of the sizes of m1 supports in the height direction is greater than the sum of the sizes of n standard containers in the height direction, which is beneficial to improve the volume and energy of the energy storage device, and further reduces the use cost of the energy storage device.

[0116] In some embodiments, the first direction is the height direction of the silo body, and along the height direction of the silo body, the height of a portion of the silo bodies is not equal to the height of another portion of the silo bodies; or the dimensions of the silo bodies along the height direction of the silo body are equal.

[0117] This facilitates greater flexibility in warehouse capacity, allowing for better matching of different needs.

[0118] This simplifies the manufacturing process and reduces costs.

[0119] In some embodiments, the first direction is the height direction of the container, the standard container is a 20-foot standard container, and the height of the standard container is 2896mm, 2591mm or 2438mm.

[0121] In this embodiment, the land wasted by the traditional requirement to reserve maintenance passages of more than 3 meters between adjacent warehouses is reduced. The grid-like warehouses only need to reserve normal paint touch-up and maintenance passages, which can improve the user's land investment returns and increase the user's energy returns per unit area.

[0122] This application embodiment also provides an energy storage device, which includes a housing and a plurality of energy units, wherein the plurality of energy units are housed within the housing;

[0123] The dimension of the cargo hold along the first direction is greater than one-third of the dimension of a standard container along the first direction, but less than one-half of the dimension of a standard container along the first direction; or,

[0124] The dimension of the silo along the first direction is greater than half the dimension of a standard container along the first direction, but less than the dimension of one standard container along the first direction.

[0125] The energy storage device provided in this application embodiment reduces the size of the storage chamber, thereby reducing the total weight of the storage chamber and its components. This helps to improve the problem of excessive weight during transportation, reduces the transportation cost of the energy storage device, and thus reduces the operating cost of the energy storage device.

Among them, power batteries are not only applied to energy storage power supply systems such as hydroelectric, thermal, wind and solar power stations, but also widely used in electric bicycles, electric motorcycles, electric vehicles and other electric vehicles, and aerospace and other fields.

[0153] The energy unit generally includes an electrode assembly. For example only, the electrode assembly includes a positive electrode, a negative electrode, and a separator disposed between the negative electrode and the positive electrode. During the charging and discharging process of the energy unit, active ions (such as lithium ions) are inserted and extracted between the positive electrode and the negative electrode. The separator is disposed between the positive electrode and the negative electrode, which can prevent the positive and negative electrodes from short-circuiting, and at the same time allow the active ions to pass through.

[0154] In some embodiments, the positive electrode can be a positive electrode sheet, which can include a positive electrode current collector and a positive electrode active material disposed on at least one surface of the positive electrode current collector.

[0155] For example, the positive electrode current collector has two opposite surfaces in its own thickness direction, and the positive electrode active material is disposed on any one or both of the two opposite surfaces of the positive electrode current collector.

[0156] For example, the positive electrode current collector can be a metal foil, a conductive polymer material, a carbon material, or a composite current collector.

The type of electrolyte is not particularly limited in the present application and can be selected as desired. The electrolyte can be in a liquid, gel or solid state.

[0167] The electrode assembly can be in a wound structure, a stacked structure, or a hybrid structure of wound and stacked.

[0168] In some embodiments, the electrode assembly is in a wound structure. The positive and negative electrode sheets are wound into the wound structure.

[0182] Power plants have increasingly high requirements for the area energy density of energy storage devices, so in order to improve the power, the total weight of the bin body and the components in the bin body is also correspondingly increased. The energy storage device needs to be transported from the production place to the use place by land and / or sea transportation, and there is a transportation weight limit for land and sea transportation in general.

[0225] The 45 feet can include: a length direction size of 13716mm, a tolerance of 0mm-10mm; a width direction size of 2438mm, a tolerance of 350mm-5mm; and a height direction size of 2591mm or 2896mm; a tolerance of 0mm-5mm.

[0226] In the embodiments of the present application, for the warehouse body 10 of various sizes, the size within ±1%, ±2%, ±3%, ±4%, ±5% of the size can be considered as the size within the tolerance range.

[0227] 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 loaded with components such as energy units 2 can be reduced, which is beneficial to improve the problem of transportation overweight, and reduces the transportation cost of the energy storage device 100.

[0228] Exemplarily, the sum of the sizes of the plurality of bin bodies 10 along the first direction is greater than the sum of the sizes of the one or more standard containers along the first direction.

[0229] That is, on the one hand, the sum of the sizes of the plurality of bin bodies 10 along the first direction is greater than the sum of the sizes of the one or more standard containers along the first direction, which means that the size of at least one bin body 10 along the first direction is as large as possible, and the capacity of the energy storage device 100 can be as large as possible under the premise of meeting the transportation weight. On the other hand, it is beneficial to increase the volume and capacity of the energy storage device 100, and further reduce the use cost of the energy storage device 100.

[0230] Of course, in other embodiments, the sum of the sizes of the plurality of bin bodies 10 along the first direction can also be equal to the sum of the sizes of the one or more standard containers along the first direction.

[0231] In some embodiments, the first direction is the height direction of the bin body 10, the standard container is a 20-foot standard container, and the height of the standard container is 2896mm, 2591mm or 2438mm.

[0232] The sum of the sizes of the m1 bin bodies 10 along the height direction is less than the height 2896mm, 2591mm or 2438mm of the 20-foot standard container, and the sum of the sizes of the m1+1 bin bodies 10 along the height direction is greater than the height 2896mm, 2591mm or 2438mm of the 20-foot standard container.

[0233] In some embodiments, the size of at least one bin body 10 in the plurality of bin bodies 10 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 the size of the standard container along the first direction.

[0234] Exemplarily, a plurality of energy units 2 can be placed in each bin body 10, or a plurality of energy units 2 can be placed in part of the bin bodies 10, and no energy units 2 can be placed in another part of the bin bodies 10. The bin bodies 10 without energy units 2 can place control modules 30, and of course, the bin bodies 10 with a plurality of energy units 2 can also place control modules 30.

[0235] Exemplarily, the size of each bin body 10 in the plurality of bin bodies 10 along the first direction can be greater than or equal to one-third of the size of the standard container along the first direction, and less than the size of the standard container along the first direction. Alternatively, the size of part of the bin bodies 10 in the plurality of bin bodies 10 along the first direction can be greater than or equal to one-third of the size of the standard container along the first direction, and less than the size of the standard container along the first direction.

[0236] Exemplarily, the energy storage device 100 can be composed of three warehouse bodies 10, the three warehouse bodies 10 are arranged in a stack along the first direction, and the sum of the sizes of the three warehouse bodies 10 along the first direction is greater than the size of one standard container along the first direction.

[0237] Exemplarily, the energy storage device 100 can be composed of two warehouse bodies 10, the two warehouse bodies 10 are arranged in a stack along the first direction, and the sum of the sizes of the two warehouse bodies 10 along the first direction is greater than the size of one standard container along the first direction.

[0238] 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 the standard container along the first direction, the energy storage device 100 has high manufacturability, high volumetric energy density, and is more convenient for transportation and installation.

[0239] In some embodiments, the size of at least one of the plurality of warehouse bodies 10 along the first direction is greater than or equal to one-half of the size of the standard container along the first direction, and less than the size of one standard container along the first direction.

[0240] Exemplarily, the energy storage device 100 can be composed of three warehouse bodies 10, the three warehouse bodies 10 are arranged in a stack along the first direction, and the sum of the sizes of the three warehouse bodies 10 along the first direction is greater than the size of one standard container along the first direction.

[0241] Exemplarily, the energy storage device 100 can be composed of three warehouse bodies 10, the three warehouse bodies 10 are arranged in a stack along the first direction, and the sum of the sizes of the three warehouse bodies 10 along the first direction is greater than the size of one standard container along the first direction.

[0242] When the size of the bin 10 along the first direction is greater than or equal to one-third of the size of the standard container along the first direction, the manufacturability of the energy storage device 100 is high, the volumetric energy density is high, and the transportation and installation are more convenient. For example, when the energy storage device 100 includes three bins 10 stacked together, each bin 10 has a plurality of energy units 2 placed inside, and the size of each bin 10 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. After the three bins 10 are stacked together, the height is higher than that of a standard container, but the weight of each bin 10 containing components such as energy units 2 is lower. In this way, each bin 10 containing components such as energy units 2 of the energy storage device 100 can be transported separately, and after being stacked at the use site, the energy storage device 100 has a higher capacity.

[0243] In some embodiments, the size of at least one bin 10 of the plurality of bins 10 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.

[0244] For example, each bin 10 can have a plurality of energy units 2 placed inside, or some bins 10 can have a plurality of energy units 2 placed inside, and some bins 10 can not have energy units 2 placed inside. The bins 10 without energy units 2 placed inside can have control modules 30 placed inside. Of course, the bins 10 with a plurality of energy units 2 placed inside can also have control modules 30 placed inside.

[0245] When the size of the bin 10 along the first direction is greater than or equal to one-third of the size of the standard container along the first direction, the manufacturability of the energy storage device 100 is high, the volumetric energy density is high, and the transportation and installation are more convenient. For example, when the energy storage device 100 includes three bins 10 stacked together, each bin 10 has a plurality of energy units 2 placed inside, and the size of each bin 10 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. After the three bins 10 are stacked together, the height is higher than that of a standard container, but the weight of each bin 10 containing components such as energy units 2 is lower. In this way, each bin 10 containing components such as energy units 2 of the energy storage device 100 can be transported separately, and after being stacked at the use site, the energy storage device 100 has a higher capacity.

[0246] Of course, in other embodiments, only one bin 10 can meet the above size requirements, and other bins 10 can not meet the above requirements, such as other bins 10 being the size of a standard container.

[0247] In some embodiments, each of the plurality of the bin bodies 10 contains a plurality of energy units 2, and each of the bin bodies 10 has a dimension along the first direction that is greater than or equal to one-half of the dimension of a standard container along the first direction and less than the dimension of a standard container along the first direction.

[0248] In some embodiments, there are m bin bodies 10, the sum of the dimensions of m1 bin bodies 10 along the first direction is less than the sum of the dimensions of n standard containers along the first direction, the sum of the dimensions of m1+1 bin bodies 10 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.

[0249] Here, by setting the sum of the dimensions of m1 bin bodies 10 along the first direction to be less than the sum of the dimensions of n standard containers along the first direction and m1 to be greater than or equal to n, that is, the dimension of each bin body 10 along the first direction is less than the dimension of a standard container along the first direction.

[0250] The m1+1 bin bodies 10 of the m bin bodies 10 refer to any m1+1 bin bodies 10 of the m bin bodies 10. For example, the energy storage device 100 has three bin bodies 10, which are the first bin body 3, the second bin body 4, and the third bin body 10. If m1+1 is equal to 2, the two bin bodies 10 can be the first bin body 3 and the third bin body 10, or the first bin body 3 and the second bin body 4, or the second bin body 4 and the third bin body 10.

[0251] It can be that m1+1 is less than m, the sum of the dimensions of m1 bin 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 bin 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 equal to 8, m1+1 is equal to 5, and n is equal to 3. Here, the five bin bodies 10 can be any five bin bodies 10 of the eight bin bodies 10.

[0252] It can also be that m1+1 is equal to m, the sum of the dimensions of m1 bin 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 bin 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 equal to 2, and the sum of the heights of the two bin bodies 10 is greater than the height of a standard container.

[0253] It can be understood that m, m1, and n are positive integers.

[0254] In some embodiments, m1=1 and n=1.

[0255] The number of the at least one container body 10 can be more than two, for example, the number of the container bodies 10 in the energy storage device 100 is three, five, or eight. The number of the at least one container body 10 can also be two.

[0256] By setting the height of the at least one container body 10 to be less than the height of one standard container, and the sum of the heights of the two container bodies 10 after stacking to be greater than the height of one standard container, the total weight of the container bodies 10 containing the energy units 2 and other components can be reduced by reducing the size of the container bodies 10, which is conducive to improving the problem of overweight transportation and reducing the transportation cost of the energy storage device 100. On the other hand, the sum of the sizes of the two container bodies 10 along the first direction is set to be greater than the sum of the sizes of one standard container along the first direction, which means that the size of the at least one container body 10 along the first direction is as large as possible, and the power of the energy storage device 100 can be as large as possible under the premise of meeting the transportation weight. In addition, it is also conducive to improving the volume and power of the energy storage device 100, and further reducing the use cost of the energy storage device 100.

[0257] In some embodiments, m1 = 2 and n = 1.

[0258] By setting the height of the at least one container body 10 to be less than the height of one standard container, and the sum of the heights of the three container bodies 10 after stacking to be greater than the height of one standard container, the manufacturability, volume energy density, transportation and installation of the energy storage device 100 are more convenient by reducing the size of the at least one container body 10. On the other hand, the sum of the sizes of the three container bodies 10 along the first direction is set to be greater than the sum of the sizes of one standard container along the first direction, which can make the power of the energy storage device 100 as large as possible under the premise of meeting the transportation weight. In addition, it is also conducive to improving the volume and power of the energy storage device 100, and further reducing the use cost of the energy storage device 100.

[0259] In some embodiments, m1 = 2 and n = 2.

[0260] By setting the height of the at least one container body 10 to be less than the height of two standard containers, and the sum of the heights of the three container bodies 10 after stacking to be greater than the sum of the heights of two standard containers after stacking, the manufacturability, volume energy density, transportation and installation of the energy storage device 100 are more convenient by reducing the size of the at least one container body 10. On the other hand, the sum of the sizes of the three container bodies 10 along the first direction is set to be greater than the sum of the sizes of one standard container along the first direction, which can make the power of the energy storage device 100 as large as possible under the premise of meeting the transportation weight. In addition, it is also conducive to improving the volume and power of the energy storage device 100, and further reducing the use cost of the energy storage device 100.

[0261] Here, the m storage bodies 10 can have the same size in the height direction, or the m storage bodies 10 can have different sizes in the height direction.

[0262] In some embodiments, referring to Figures 6 to 13 The energy storage device 100 further comprises a connecting mechanism (not shown in the figure) configured to connect two adjacent storage bodies 10 in the height direction of the storage bodies 10. The connecting mechanism comprises a support 43 arranged between the two adjacent storage bodies 10 in the height direction. The sum of the sizes of m1 storage bodies 10 in the height direction and the sum of the sizes of m1-1 supports 43 in the height direction is less than the sum of the sizes of n standard containers in the height direction, and the sum of the sizes of m1+1 storage bodies 10 in the height direction and the sum of the sizes of m1 supports 43 in the height direction is greater than the sum of the sizes of n standard containers in the height direction.

[0263] Alternatively, the storage bodies 10 assembled for transportation in the height direction are connected and fixed by the supports 43. The sizes of the m1 storage bodies 10 to form the n standard containers further include the height sizes of the supports 43 therebetween. That is, when the supports 43 are arranged, the size of some of the m1 storage bodies 10 in the height direction can be the sum of the height of the storage body itself and the height of the support 43 connected thereto. Because the supports 43 connecting the storage bodies 10 in the height direction also occupy the height size of the storage bodies 10 to some extent.

[0264] For example, when the m1 storage bodies 10 are all connected and fixed for transportation by the supports 43, the sum of the sizes of the m1 storage bodies 10 in the height direction and the sum of the sizes of the m1-1 supports 43 in the height direction is less than the sum of the sizes of n standard containers in the height direction, and the sum of the sizes of the m1+1 storage bodies 10 in the height direction and the sum of the sizes of the m1 supports 43 in the height direction is greater than the sum of the sizes of n standard containers in the height direction. Alternatively, the number of supports 43 between the m1 storage bodies 10 can be less than m1-1, and when these storage bodies 10 are assembled to the size of the standard container, the size of the m1 storage bodies 10 and the actual size of the supports 43 are included.

[0265] The connection of the bin body 10 through the connecting mechanism can make the stacking of the bin body 10 more stable. When the bin body 10 is transported, the sum of the sizes of the m1 bin bodies 10 along the height direction plus the sum of the sizes of the support members 43 arranged between adjacent two of the m1 bin bodies 10 along the height direction is less than the sum of the sizes of the n standard containers along the height direction, and the sum of the sizes of the m1+1 bin bodies 10 along the height direction plus the sum of the sizes of the m1 support members 43 along the height direction is greater than the sum of the sizes of the n standard containers along the height direction, which is beneficial to increase the volume and the electric quantity of the energy storage device 100, and further reduces the use cost of the energy storage device 100.

[0266] When the energy storage device 100 of the embodiment of the present application uses the support member 43 during transportation, and the bin bodies 10 constituting the energy storage device 100 do not need the support member 43, the "the sum of the sizes of the m1 bin bodies 10 along the height direction is less than the sum of the sizes of the n standard containers along the height direction, and the sum of the sizes of the m1+1 bin bodies 10 along the height direction is greater than the sum of the sizes of the n standard containers along the first direction" should be understood as including the height of the used support member 43. That is, the sum of the sizes of the m1 bin bodies 10 along the height direction is less than the sum of the sizes of the n standard containers along the height direction minus the sum of the heights of the used support members 43, and the sum of the sizes of the m1+1 bin bodies 10 along the height direction is greater than the sum of the sizes of the n standard containers along the height direction minus the sum of the heights of the used support members 43. Such a case also belongs to the case of the embodiment of the present application.

[0267] In some embodiments, referring to Figures 3 to 13 , the first direction is the height direction of the bin body 10, the size of the bin body 10 along the length direction is consistent with the size of the standard container along the length direction, and the size of the bin body 10 along the width direction is consistent with the size of the standard container along the width direction.

[0268] In this embodiment, by setting the size of the bin body 10 along the length direction to be consistent with the size of the standard container along the length direction, and setting the size of the bin body 10 along the width direction to be consistent with the size of the standard container along the width direction, it is beneficial to match the existing standard container transportation tools and spreaders, and reduce the transportation cost of the energy storage device 100, thereby reducing the use cost of the energy storage device 100.

[0269] By setting the size of the bin body 10 in the height direction to be smaller than the size of a standard container in the height direction, the bin body 10 does not exceed the height of the corresponding standard container in the height direction of the bin body 10 during transportation, which is conducive to improving the convenience of the bin body 10 during transportation and reducing transportation costs. The size of the bin body 10 in the length direction and the size of the bin body 10 in the width direction are consistent with the standard container, so that the horizontal area occupied by the bin body 10 during transportation is consistent with the standard container, which is conducive to matching the existing standard container transportation tools and lifting devices, thereby reducing the transportation cost of the energy storage device 100, and thus reducing the use cost of the energy storage device 100.

[0270] At the same time, the sum of the sizes of the m1 bin bodies 10 in the first direction is less than the sum of the sizes of the n standard containers in the first direction, and the sum of the sizes of the m1+1 bin bodies 10 in the first direction is greater than the sum of the sizes of the n standard containers in the first direction, which is conducive to improving the volume and capacity of the energy storage device 100, and further reducing the use cost of the energy storage device 100. By reducing the size of the bin body 10, the total weight of the bin body 10 containing components such as energy units 2 can be reduced, which is conducive to improving the problem of overweight transportation and reducing the transportation cost of the energy storage device 100. On the other hand, the sum of the sizes of the m1+1 bin bodies 10 in the first direction is greater than the sum of the sizes of the n standard containers in the first direction, which means that the size of at least one bin body 10 in the first direction is as large as possible. Under the premise of meeting the transportation weight, the capacity of the energy storage device 100 can be improved as much as possible. In addition, it is also conducive to improving the volume and capacity of the energy storage device 100, and further reducing the use cost of the energy storage device 100.

[0271] In some embodiments, the energy storage device includes an energy storage cabinet 100a, which includes a bin body and components arranged in the bin body, and the weight of the energy storage cabinet 100a is M, which is less than or equal to 35 tons.

[0272] The components arranged in the bin body 10 include, for example, energy units 2, connecting pipelines, control modules 30, or thermal management modules 20.

[0273] Here, the energy storage cabinet 100a refers to a cabinet body that can be transported and lifted individually.

[0274] For example, the weight of the energy storage cabinet 100a can be any one of 10 tons, 15 tons, 20 tons, 25 tons, 30 tons, 35 tons, or any point value between any two of them.

[0275] During the lifting of the energy storage cabinet 100a, the lifting of the related lifting device is facilitated, and the transfer work of the energy storage cabinet 100a is facilitated.

[0276] In order to make a single energy storage cabinet 100a meet the transportation limit requirements of some countries, the overall weight of the energy storage cabinet 100a is controlled to be less than 35 tons, and the integration of the energy storage cabinet 100a is as high as possible, thereby reducing the workload of on-site installation; at the same time, the energy per unit area is improved, and the customer's cost investment is reduced.

[0277] In this embodiment, by setting the sum of the sizes of the m1 bin bodies 10 along the first direction to be less than the sum of the sizes of the n standard containers along the first direction, the sum of the sizes of the m1+1 bin bodies 10 along the first direction is greater than the sum of the sizes of the n standard containers along the first direction, and the weight of the energy storage cabinet 100a is controlled to be less than 35 tons, the energy storage cabinet 100a can be normally transported and hoisted in multiple transportation scenarios such as land transportation and sea transportation, to a certain extent, the problem of increased transportation cost caused by the need to disassemble and transport the energy storage cabinet 100a or the need for special equipment to transfer the energy storage cabinet 100a due to the weight of the energy storage cabinet 100a exceeding the carrying limit of the road, bridge, hoist and the like can be avoided.

[0278] In some embodiments, referring to Figure 3 , the first direction is the height direction of the bin body 10, and the height size of the bin body 10 is h, 850mm≤h<2896mm.

[0279] Exemplarily, the height size of the bin 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, 2895mm or any point value between any two of them, and it needs to meet that the sum of the sizes of the m1 bin bodies 10 along the first direction is less than the sum of the sizes of the n standard containers along the first direction, and the sum of the sizes of the m1+1 bin bodies 10 among the m bin bodies 10 along the first direction is greater than the sum of the sizes of the n standard containers along the first direction.

[0280] In this embodiment, by setting the height size of the bin body 10 to 850mm≤h<2896mm, the total weight of the bin body 10 and its internal components can be controlled to be less than 35 tons, and the volume and capacity of the energy storage device 100 can be improved as much as possible, thereby further reducing the use cost of the energy storage device 100.

[0281] In some embodiments, the first direction is the height direction of the bin body 10, and the height size of the bin body 10 is h, 1300mm≤h≤2400mm.

[0282] Exemplarily, the height dimension of the bin body 10 can be any one of 1300 mm, 1350 mm, 1400 mm, 1450 mm, 1500 mm, 1550 mm, 1600 mm, 1650 mm, 1700 mm, 1750 mm, 1800 mm, 1850 mm, 1900 mm, 1950 mm, 2000 mm, 2050 mm, 2100 mm, 2150 mm, 2200 mm, 2250 mm, 2300 mm, 2350 mm, 2400 mm, or any point value between any two of them, and needs to meet that the sum of the dimensions of the m1 bin bodies 10 along the first direction is less than the sum of the dimensions of the n standard containers along the first direction, and the sum of the dimensions of the m1+1 bin bodies 10 among the m bin bodies 10 along the first direction is greater than the sum of the dimensions of the n standard containers along the first direction.

[0283] The energy storage device 100 provided by the embodiment of the present application sets the sum of the dimensions of the m1 bin bodies 10 along the first direction to be less than the sum of the dimensions of the n standard containers along the first direction, and m1≥n, that is, the dimension of the bin body 10 along the first direction is less than the dimension of a standard container along the first direction. On the one hand, by reducing the dimension of the bin body 10, the total weight of the bin body 10 and its internal components can be less than the weight of a standard container, so that the standard lifting appliance can be matched, that is, under the condition that the weight does not exceed the transportation and road limit, the transportation tool of the existing standard container can also be matched, which is beneficial to improve the transportation overweight problem and reduce the transportation cost of the energy storage device 100, thereby reducing the use cost of the energy storage device 100. On the other hand, by setting the sum of the dimensions of the m1+1 bin bodies 10 along the first direction to be greater than the sum of the dimensions of the n standard containers along the first direction, the volume and the electric quantity of the energy storage device 100 are improved, and the use cost of the energy storage device 100 is further reduced.

[0284] In some embodiments, referring to Figure 4 , the energy storage device 100 comprises a thermal management module 20, and the thermal management module 20 is configured to manage the temperature of the plurality of energy units 2 of the energy storage device 100.

[0285] In this embodiment, by setting the thermal management module 20, the thermal management module 20 can manage the temperature of the energy unit 2 and reduce the risk of temperature runaway of the energy unit 2.

[0286] In some embodiments, referring to Figure 4 , the bin body 10 is m, and the plurality of energy units 2 are accommodated in the m bin bodies 10, and the thermal management module 20 is configured to manage the temperature of the plurality of energy units 2 of the m bin bodies 10.

[0287] That is, the energy storage device 100 shares the thermal management module 20 to form a complete system, which is beneficial to save space.

[0288] In some embodiments, referring to Figure 4 , the energy storage device 100 comprises m storage bodies 10, each of which contains a plurality of energy units 2, and the control module 30 is configured to electrically control the plurality of energy units 2 in the m storage bodies 10.

[0289] That is, the energy storage device 100 shares the control module 30, forming a complete system, which is conducive to saving space.

[0290] In some embodiments, referring to Figure 4 , the control module 30 is contained in at least one storage body 10.

[0291] Here, it can be that part of the storage bodies 10 contain the control module 30, or all of the storage bodies 10 contain the control module 30.

[0292] In the embodiment in which part of the storage bodies 10 contain the control module 30, the storage bodies 10 without the control module 30 can be electrically controlled by the control module 30 in other storage bodies 10. For example, the energy storage device 100 comprises two storage bodies 10, namely a first storage body 3 and a second storage body 4, wherein the first storage body 3 contains the control module 30, the second storage body 4 contains the energy unit 2, and the control module 30 in the first storage body 3 can electrically control the energy unit 2 in the second storage body 4.

[0293] When all of the storage bodies 10 contain the control module 30, and the first storage body 3 and the second storage body 4 are provided with a plurality of energy units 2, the control modules 30 in all of the storage bodies 10 can jointly act to electrically control the plurality of energy units 2 in the first storage body 3 and the second storage body 4; or the control modules 30 in each of the storage bodies 10 can act independently, that is, the control module 30 in the first storage body 3 electrically controls the plurality of energy units 2 in the first storage body 3, and the control module 30 in the second storage body 4 electrically controls the plurality of energy units 2 in the second storage body 4.

[0294] In some embodiments, referring to Figure 4 , the thermal management module 20 is contained in at least one storage body 10.

[0295] The thermal management module 20 can be a liquid cooling unit, an air conditioner, a ground source cooling device, or a sea liquid cooling device.

[0296] Here, it can be that part of the storage bodies 10 contain the thermal management module 20, or all of the storage bodies 10 contain the thermal management module 20.

[0297] In the embodiment in which some of the cartridges 10 contain the thermal management module 20, the cartridges 10 without the thermal management module 20 can manage the temperature of the energy units 2 by the thermal management module 20 in other cartridges 10. Exemplarily, the energy storage device 100 includes two cartridges 10, i.e., a first cartridge 3 and a second cartridge 4, wherein the first cartridge 3 contains the thermal management module 20, and the second cartridge 4 does not contain the thermal management module 20, and the thermal management module 20 of the first cartridge 3 can manage the temperature of the energy units 2 in the first cartridge 3 and the second cartridge 4.

[0298] When all the cartridges 10 contain the thermal management module 20, and a plurality of energy units 2 are arranged in the first cartridge 3 and the second cartridge 4, the thermal management modules 20 in all the cartridges 10 can jointly act to control the temperature of the plurality of energy units 2 in the first cartridge 3 and the second cartridge 4; or the thermal management modules 20 in each cartridge 10 can independently act, i.e., the thermal management module 20 in the first cartridge 3 controls the temperature of the plurality of energy units 2 in the first cartridge 3, and the thermal management module 20 in the second cartridge 4 controls the temperature of the plurality of energy units 2 in the second cartridge 4.

[0299] As an example, when the control module 30 and the thermal management module 20 in the first cartridge 3 and the second cartridge 4 can independently operate, the first cartridge 3 and the internal components thereof can be considered as an independent energy storage device 100; the second cartridge 4 and the internal components thereof 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 cartridge 3 and the second cartridge 4 need to jointly control the energy units in the two cartridges, the first cartridge 3 and the internal components thereof, and the second cartridge 4 and the internal components thereof can be considered as a common energy storage device 100. Of course, at this time, only part of the energy units 2 can be operated, for example, only the energy units 2 in the first cartridge 3 are electrically controlled and temperature controlled, so that the energy units 2 in the first cartridge 3 input or output electric energy, and the energy units 2 in the second cartridge 4 do not output electric energy, which can be determined according to actual use requirements.

[0300] Due to the size of the energy units 2, there can be a case that the energy units 2 cannot be fully inserted into the cartridge 10. By arranging the control module 30 and / or the thermal management module 20 in the cartridge 10, the space in the cartridge 10 can be fully utilized, and the space utilization of the cartridge 10 is further improved.

[0301] In addition, the control module 30 and / or the thermal management module 20 are installed together with the cartridge 10, the pipelines and lines of the control module 30 and / or the thermal management module 20 are connected when the product is shipped, the installation workload of the pipelines and lines of the control module 30 and / or the thermal management module 20 is reduced, and the installation cost is reduced.

[0302] Of course, in other embodiments, the control module 30 and / or the thermal management module 20 can also be disposed outside the bin body 10.

[0303] Exemplarily, at least part of the control module 30 is disposed outside the bin body 10.

[0304] That is, part of the control module 30 can be disposed outside the bin body 10, and part of the control module 30 can be disposed inside the bin body 10; and all of the control module 30 can also be disposed outside the bin body 10.

[0305] Here, by disposing at least part of the control module 30 outside the bin 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 will not occupy the space inside the bin body 10. In addition, it is also beneficial to maintain and replace the control module 30.

[0306] Here, the control module 30 disposed outside the bin body 10 can be connected with at least one bin body 10, or the control module 30 disposed outside the bin body 10 is separately disposed from the bin body 10, and the two are connected through a connection line or a connection pipeline.

[0307] Exemplarily, at least part of the thermal management module 20 is disposed outside the bin body 10.

[0308] That is, part of the thermal management module 20 can be disposed outside the bin body 10, and part of the thermal management module 20 can be disposed inside the bin body 10; and all of the thermal management module 20 can also be disposed outside the bin body 10.

[0309] Here, by disposing at least part of the thermal management module 20 outside the bin body 10, the influence of the thermal management module 20 on the energy unit 2 can be reduced to a certain extent, and the thermal management module 20 will not occupy the space inside the bin body 10. In addition, it is also beneficial to maintain and replace the thermal management module 20.

[0310] Here, the thermal management module 20 disposed outside the bin body 10 can be connected with at least one bin body 10, or the thermal management module 20 disposed outside the bin body 10 is separately disposed from the bin body 10, and the two are connected through a connection line or a connection pipeline.

[0311] Of course, part of the structure of the thermal management module 20 can also be disposed outside the bin body 10, and another part of the structure can be disposed inside the bin body 10.

[0312] Exemplarily, the thermal management module 20 includes a heat dissipation fan, and the heat dissipation fan is disposed outside the bin body 10. For example, the thermal management module 20 includes a heat dissipation fan and a heat exchanger, and the heat dissipation fan and the heat exchanger are disposed outside the bin body 10.

[0313] In this way, it is beneficial for the heat dissipation fan, the heat dissipation fan and the heat exchanger to exchange heat with the outside, thereby improving the heat exchange efficiency.

[0314] In some embodiments, the energy storage device 100 can also not include the thermal management module 20.

[0315] In some embodiments, referring to Figure 14 , the control module 30 includes at least one of a master control module 301, a power distribution module 302, a general control module 303, and a fire control module 304.

[0316] The energy unit 2 and the master control module 301 are electrically connected. The master control module 301 and the general control module 303 are electrically connected. The master control module 301, the general control module 303, and the fire control module 304 are electrically connected to the power distribution module 302.

[0317] The master control module 301 is used to control the input and output of high-voltage electrical energy of the energy unit 2 in the bin body 10. The general control module 303 is used to control the switching action of the master control module 301 in the bin body 10.

[0318] The fire control module 304 is used to control the action of the fire-fighting element when the bin body 10 temperature imbalance causes a fire. The fire-fighting element can be a fire extinguisher, etc. The fire-fighting element can be arranged in the bin body 10.

[0319] The power distribution module 302 is used to electrically connect the master control module 301, the general control module 303, and the fire control module 304, so as to facilitate the circuit conduction of the master control module 301, the general control module 303, and the fire control module 304, and maintain the normal operation of the master control module 301, the general control module 303, and the fire control module 304.

[0320] Here, in the embodiment in which the energy storage device 100 includes a plurality of control modules 30, the plurality of control modules 30 can be the same or different.

[0321] Exemplarily, each bin body 10 is provided with a control module 30, that is, the control module 30 corresponds to the bin body 10 one by one, and one control module 30 corresponds to control the input and output of electrical energy of the energy unit 2 in one bin body 10, so as to facilitate the electrical control of the control module 30 on the energy unit 2.

[0322] Exemplarily, referring to Figures 6 to 13 , part of the bin bodies 10 are provided with control modules 30, and the other part of the bin bodies 10 are not provided with control modules 30, that is, one control module 30 corresponds to control the input or output of electrical energy of the energy unit 2 in multiple bin bodies 10. For example, when the number of bin bodies 10 is two, one of the bin bodies 10 is provided with a control module 30, and the other bin body 10 is not provided with a control module 30. The control module 30 corresponds to control the input or output of electrical energy of the energy unit 2 in the two bin bodies 10.

[0323] Of course, one bin body 10 can have multiple control modules 30, one bin body 10 can have multiple energy units 2, multiple energy units 2 can be connected in series to form a battery cluster, multiple battery clusters can be connected in parallel, and one control module 30 can control one or more battery clusters.

[0324] The thermal management module 20 includes a heat exchange unit, 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 the heat exchange pipeline 40 (for example, a liquid cooling pipeline 90), so as to manage the temperature of the energy unit 2 and reduce the risk of temperature runaway of the energy unit 2.

[0325] Exemplarily, each bin body 10 is provided with a thermal management module 20, that is, the thermal management module 20 corresponds to the bin body 10 one by one, and one thermal management module 20 corresponds to manage the temperature of the energy unit 2 in one bin body 10.

[0326] Exemplarily, please refer to Figures 6 to 13 Some bin bodies 10 are provided with a thermal management module 20, and the other bin bodies 10 are not provided with a thermal management module 20, that is, one thermal management module 20 corresponds to manage the temperature of the energy unit 2 in multiple bin bodies 10. For example, when the number of bin bodies 10 is two, one bin body 10 is provided with a thermal management module 20, and the other bin body 10 is not provided with a thermal management module 20. The thermal management module 20 can exchange heat with the energy units 2 in the two bin bodies 10 through the heat exchange pipeline 40 (for example, a liquid cooling pipeline 90), that is, the thermal management module 20 can correspond to manage the temperature of the energy units 2 in the two bin bodies 10.

[0327] In some embodiments, the bin body 10 containing the thermal management module 20 has a size along the first direction greater than the size of the other bin bodies 10 along the first direction.

[0328] In this way, it is beneficial to increase the space in the bin body 10 containing the thermal management module 20, so as to reduce the influence of the thermal management module 20 on the accommodation volume of the energy unit 2, that is, to make the bin body 10 have enough space to accommodate the energy unit 2 and the thermal management module 20. In addition, a higher refrigeration capacity thermal management module 20 can be placed to improve the thermal management capability.

[0329] Please refer to Figure 4 The bin body 10 includes the bin body 10 and the energy unit 2, and the energy unit 2 has multiple energy units 2, and the multiple energy units 2 are accommodated in the bin body 10.

[0330] Exemplarily, the bin body 10 can be used to accommodate at least one of the control module 30 and the thermal management module 20.

[0331] In some embodiments, referring to Figures 3 to 13 At least part of the interior of the storage body 10 has an energy storage 11 and a control storage 12. The energy storage 11 is used to accommodate at least one energy unit 2, and at least part of the control module 30 and / or at least part of the thermal management module 20 are accommodated in the control storage 12.

[0332] Here, at least part of the control module 30 and / or at least part of the thermal management module 20 accommodated in the control storage 12 means that at least part of the control module 30 can be accommodated in the control storage 12, at least part of the thermal management module 20 can be accommodated in the control storage 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 storage 12.

[0334] Exemplarily, in the embodiment in which the interiors of the plurality of storage bodies 10 have the control storage 12, the control modules 30 in all of the storage bodies 10 can jointly act, or the control modules 30 in each of the storage bodies 10 can act independently.

[0335] Exemplarily, in the embodiment in which the interiors of the plurality of storage bodies 10 have the thermal management module 20, the thermal management modules 20 in all of the storage bodies 10 can jointly act, or the thermal management modules 20 in each of the storage bodies 10 can act independently.

[0336] In this embodiment, by arranging the interiors of at least part of the storage bodies 10 with the energy storage 11 and the control storage 12, and arranging at least part of the control module 30 and / or at least part of the thermal management module 20 in the storage body 10, the space in the storage body 10 can be fully utilized, and the space utilization rate of the storage body 10 is further improved.

[0337] In some embodiments, at least part of the storage body 10 comprises a first partition 101, and the first partition 101 is arranged between the energy storage 11 and the control storage 12, and the energy storage 11 and the control storage 12 share the first partition 101.

[0338] Here, the first partition 101 can include a metal plate.

[0339] Here, the first partition 101 is conducive to improving the structural strength of the storage body 10, and is also conducive to improving the sealing performance and thermal insulation performance of the energy storage 11.

[0340] The first partition 101 is provided with a heat exchange pipeline 40 and a connection wire harness 50, the connection wire harness 50 includes a high-voltage wire harness 51 and / or a low-voltage wire harness 52, the heat management module 20 in the control bin 12 can exchange heat with the energy unit 2 in the energy bin 11 through the heat exchange pipeline 40 (for example, a liquid cooling pipeline 90), and the control module 30 in the control bin 12 can electrically control the energy unit 2 in the energy bin 11 through the connection wire harness 50.

[0341] As an example, when the heat exchange pipeline 40 and the connection wire harness 50 pass through the first partition 101, the passing position can be sealed.

[0342] As an example, the inside of the first partition 101 is filled with a heat insulation medium.

[0343] Here, the heat insulation medium can be some material capable of heat insulation, such as heat insulation cotton, etc.

[0344] The heat insulation medium is beneficial to improve the structural strength of the first partition 101, and can also play a fire-retardant and heat-preserving effect, which is beneficial to reduce the heat loss of the energy bin and the influence of external heat on the energy unit in the energy bin.

[0345] Here, in some embodiments, the bin body 10 includes a plurality of control bins 12, the control bin 12 can contain the control module 30 and the heat management module 20, or all control bins 12 contain the control module 30, or all control bins 12 contain the heat management module 20.

[0346] In some embodiments, the control bin 12 has a plurality of first partitions 101, and the first partition 101 can be arranged between adjacent control bins 12, and the adjacent control bins 12 share the first partition 101.

[0347] As an example, the first partition 101 separates the heat management module 20 and the control module 30, reduces the risk of interference between the heat management module 20 and the control module 30, and improves the reliability of the energy storage device 100.

[0348] The heat management module 20 and the control module 30 are separated by the first partition 101, the first partition 101 can separate the heat management module 20 and the control module 30, which can reduce the interference of the heat management module 20 to the control module 30, that is, can reduce the electromagnetic interference of the high-voltage line to the low-voltage, and can also reduce the influence of external rainfall or sunlight on the control module 30.

[0349] The energy bin 11 and the control bin 12 can be arranged in various ways.

[0350] In some embodiments, at least part of the control bin 12 and the energy bin 11 are arranged along the height direction of the bin body 10.

[0351] Here, some of the control chambers 12 and energy chambers 11 can be arranged along the height of the chamber body 10, or all of the control chambers 12 and energy chambers 11 can be arranged along the height of the chamber body 10.

[0352] As an example, the control chamber 12 is positioned above the energy chamber 11, so that the components inside the control chamber can shield the heat radiation from the top, reducing the impact of heat radiation on the interior of the energy chamber 11.

[0353] For example, at least part of the control chamber 12 and the energy chamber 11 are arranged along the length of the chamber body 10.

[0354] Here, some of the control chambers 12 and energy chambers 11 can be arranged along the length of the chamber body 10, or all of the control chambers 12 and energy chambers 11 can be arranged along the length of the chamber body 10.

[0355] Here, by arranging the control compartment 12 at the end of the compartment 10, the space utilization inside the compartment 10 is maximized. In addition, the control compartment 12 and the energy compartment 11 can be arranged closer together, which is beneficial to improving the structural compactness.

[0356] In some embodiments, please refer to Figures 3 to 4 At least part of the control compartment 12 contains a thermal management module 20, which is located on top of the topmost compartment 10.

[0357] In this embodiment, the thermal management module 20 is located at the top of the topmost compartment 10. The absence of obstructions above the thermal management module 20 facilitates heat dissipation, thereby extending the lifespan of the energy storage device 100. This also helps lower the overall center of gravity of the individual compartment 10, improving transportation safety. Furthermore, the compartmentalized design with the energy compartment 11 enhances the thermal insulation of the energy compartment 11, while the thermal management module 20 shields the top from heat radiation, reducing its impact on the interior of the energy compartment 11.

[0358] In some embodiments, please refer to Figures 6 to 7 At least part of the control compartment 12 contains a control module 30. The control module 30 and the energy compartment 11 are arranged along the height of the compartment 10.

[0359] In other words, the control module 30 can be located above the energy chamber 11, below the energy chamber 11, or in the middle of the two energy chambers 11 along the height direction.

[0360] For example, when the number of the bins 10 is two, the control module 30 is arranged on the top of the lower bin 10, i.e. above the energy bin 11 of the lower bin 10, the operation part height meets the ergonomic requirements, the maintenance personnel standing on one side of the bin 10 can reach the operation handle of the control part with hands, which is convenient for maintenance and repair, and meanwhile, the control bin 12 on the top is beneficial to shorten the length of the high-voltage wire harness 51 and the low-voltage wire harness 52 connected between the upper bin 10, thereby reducing the cost.

[0361] In some embodiments, referring to Figures 8 to 9 , at least part of the control bin 12 contains the control module 30. The control module 30 is arranged along the length direction of the bin 10 with the energy bin 11.

[0364] Exemplarily, the connecting pipelines can be liquid cooling pipelines 90, high-voltage wire harnesses 51, low-voltage wire harnesses 52, fire-fighting pipelines, water fire-fighting pipelines, etc.

[0365] The pipeline bin 13 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, that is, the connecting pipelines and / or connecting wires between the control module 30, the thermal management module 20 and the energy unit 2 can be partially arranged in the pipeline bin 13 or can be completely arranged in the pipeline bin 13.

[0366] Of course, the pipeline bin 13 can also be used to accommodate other components of the energy storage device 100, such as a fire-fighting control module, etc.

[0367] Exemplarily, the high-voltage wire harnesses 51 and the low-voltage wire harnesses 52 connected between the pipeline bin 13 and the energy bin 11 and the control bin 12 are connected through the connectors mounted on the partition wall; the pipeline connection between the pipeline bin 13 and the energy bin 11 is connected through the liquid cooling adapter; the through-wall interfaces are all sealed.

[0368] In this embodiment, the energy storage device 100 is provided with the pipeline bin 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 beneficial to wiring and piping, and is beneficial to making the layout of the connecting pipelines reasonable and facilitating maintenance and replacement.

[0370] In some embodiments, part of the cabinet 10 is provided with a pipeline cabinet 13, and the other part of the cabinet 10 is not provided with a pipeline cabinet 13.

[0371] Part of the cabinet 10 is provided with a pipeline cabinet 13, and the other part of the cabinet 10 is not provided with a pipeline cabinet 13, that is, one pipeline cabinet 13 corresponds to accommodate at least part of the connecting pipelines between the control module 30, the thermal management module 20 and the energy unit 2 of multiple cabinets 10. For example, when the number of cabinets 10 is two, one of the cabinets 10 is provided with a pipeline cabinet 13, and the other cabinet 10 is not provided with a pipeline cabinet 13, and the pipeline cabinet 13 corresponds to accommodate at least part of the connecting pipelines between the control module 30, the thermal management module 20 and the energy unit 2 of the two cabinets 10.

[0373] That is, the pipeline cabinet 13 can be at the left end of the energy cabinet 11, or at the right end of the energy cabinet 11, or in the middle of the two energy cabinets 11 along the length direction.

[0374] Of course, in the embodiment with the control cabinet 12, the pipeline cabinet 13 and the energy cabinet 11 can be arranged along the length direction of the cabinet 10, or arranged along the height direction of the cabinet 10.

[0375] In other embodiments, please refer to Figure 16 The pipeline cabinet 13 is arranged outside the cabinet 10, exemplarily, by arranging a protective cover 60, the interior of the protective cover 60 has a pipeline cabinet 13, or the protective cover 60 and the cabinet 10 define a pipeline cabinet 13.

[0376] It should be noted that in the embodiment in which the pipeline cabinet 13 is arranged outside the cabinet 10, the pipeline cabinet 13 does not belong to the cabinet 10, and thus the size of the pipeline cabinet 13 is not included in the size of the cabinet 10.

[0377] In some embodiments, please refer to Figures 6 to 9 At least part of the compartment 10 includes a second partition 102, which is disposed between the energy compartment 11 and the pipeline compartment 13, and the energy compartment 11 and the pipeline compartment 13 share the second partition 102.

[0378] Here, the second separator 102 may include a metal plate.

[0379] Here, the second partition 102 helps to improve the structural strength of the chamber 10, and also helps to improve the sealing and heat preservation performance of the energy chamber 11.

[0382] Here, the third partition 103 helps to improve the structural strength of the chamber 10, and also helps to improve the sealing and insulation performance of the partial control chamber 12.

[0383] For example, the control compartment 12 containing the thermal management module 20 can be connected to the pipeline compartment 13 so that the energy compartment 11 can be connected to the control compartment 12 containing the thermal management module 20 through the pipeline compartment 13.

[0384] For example, the control compartment 12, which houses the control module 30, can be isolated from the pipeline compartment 13.

[0385] In some embodiments, please refer to Figure 4 The first doors 104 of the energy compartment 11, control compartment 12, and pipeline compartment 13 are all located on the front side of the compartment body 10.

[0386] In this embodiment, by setting the first doors 104 of the energy chamber 11, control chamber 12 and pipeline chamber 13 on the front side of the chamber body 10, maintenance can be carried out through their respective first doors 104. This reduces the land waste that traditional chamber bodies 10 must reserve more than 3m of maintenance passage between each chamber body 10. The grid-like chamber bodies 10 only need to reserve normal paint touch-up maintenance passages, which can improve the user's land investment returns and increase the user's energy returns per unit area.

[0466] When E / (a x b)≥250KW / m 2 , the energy storage device 100 can have a larger energy density, and the practicality of the energy storage device 100 is improved; when E / (a x b)≤700KW / m 2 , the risk of the mass of the bin body 10 being too large to crush other bin bodies 10 can be reduced, and the transportation of the bin body 10 is facilitated. Therefore, when 250KW / m 2 ≤E / (a x b)≤700KW / m 2 , the energy density of the energy storage device 100 and the mass of the bin body 10 are considered, the practicality of the energy storage device 100 is improved, and the transportation of the energy storage device 100 is facilitated.

[0467] In some embodiments, 450KW / m 2 ≤E / (a x b)≤600KW / m 2 .

[0468] E / (a x b) can be any one of 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 , or any point value between any two of them.

[0470] In some embodiments, along the height direction of the bin body 10, two adjacent bin bodies 10 are welded, clamped, locked, or connected by a fixing member.

[0471] The fastener can be at least one of bolts, nuts, pins, screws, or rivets. Of course, the fastener may also include a fixing plate to securely connect two adjacent compartments 10 along the height direction.

[0472] For example, two adjacent compartments 10 are connected by a central twist lock.

[0473] By connecting two adjacent compartments 10 along the height direction with fasteners, the fasteners can limit the movement of the two adjacent compartments 10 along the height direction, which helps to reduce the risk of mutual movement between the two adjacent compartments 10 after stacking, and thus helps to improve the structural stability of the energy storage device 100.

[0474] In some embodiments, please refer to Figures 6 to 9 ,as well as Figure 15 The multiple compartments 10 include a first compartment 3 and a second compartment 4.

A limit pin 42 is provided at the bottom of the first compartment 3, and a limit hole 411 is provided at the top of the second compartment 4. The limit pin 42 is engaged with the limit hole 411.

[0475] The compartment 10 includes a first compartment 3 and a second compartment 4. The same compartment 10 is the first compartment 3 relative to the compartment 10 below it, and the second compartment 4 relative to the compartment 10 above it. In other words, a compartment 10 can be both the first compartment 3 and the second compartment 4. Alternatively, a limiting pin 42 can be provided at the bottom of a compartment 10, and a limiting hole 411 can be provided at its top.

[0476] Thus, by using a simple structure, the two adjacent compartments 10 along the height direction can restrict the relative movement of the two adjacent compartments 10 through the cooperation of the limiting pin 42 and the limiting hole 411.

[0477] The limiting hole 411 at the top of the second compartment 4 can be an opening for hoisting the compartment 10. In this way, during the hoisting stage of the compartment 10, the opening is used to hoist the compartment 10. After the compartment 10 is hoisted, the opening at the top of the compartment 10 is used to cooperate with the limiting pin 42 at the bottom of the adjacent upper compartment 10 to achieve the limiting of the two adjacent compartments 10. This helps to simplify the structure of the compartment 10.

[0478] In some embodiments, please refer to Figures 6 to 9 ,as well as Figure 15 The bottom of the first compartment 3 is provided with a first limiting member 31, and the first limiting member 31 is provided with a limiting groove 311. The top of the second compartment 4 is provided with a second limiting member 41, 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.

[0479] The second limiting member 41 can be the aforementioned hoisting portion, and the limiting hole 411 can be the aforementioned opening. The limiting hole 411 can also be a hole provided on the bin body 10.

[0480] 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 of the two adjacent bin bodies 10 and cooperates with the limiting hole 411 of the lower bin body 10 of the two adjacent bin bodies 10, so that the relative movement of the two adjacent bin bodies 10 is limited by a simple structure.

[0481] In some embodiments, please refer to Figures 10 to 13 The first direction is the height direction of the bin body 10, and the heights of the part of the bin bodies 10 are not equal to the heights of the other part of the bin bodies 10 along the height direction of the bin body 10.

[0482] For example, the height of the upper bin body 10 can be greater than the height of the lower bin body 10, or the height of the upper bin body 10 can be less than the height of the lower bin body 10.

[0483] In this way, the flexibility of the capacity of the bin body 10 is improved, and different requirements can be matched.

[0484] In some embodiments, the sizes of the m bin bodies 10 along the height direction of the bin body 10 are equal.

[0485] In this way, the manufacturing process is simplified, and the cost is reduced.

[0486] The embodiments of the present application also provide a storage device 100, which comprises a bin body 10 and a plurality of energy units 2, and the plurality of energy units 2 are contained in the bin body 10. The size of the bin body 10 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 a standard container along the first direction, or the size of the bin body 10 along the first direction is greater than one-half of the size of a standard container along the first direction and less than the size of a standard container along the first direction.

[0487] The bin body 10 contains a plurality of energy units 2, which can be a battery module or a battery pack.

[0488] The size of the bin 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 bin body 10, the total weight of the bin body 10 loaded with the energy unit 2 and other components can be reduced, which is conducive to improving the problem of overweight transportation and reducing the transportation cost of the energy storage device 100. The size of the bin body 10 cannot be infinitely small. When the size of the bin 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.
