[0111] In order to make the technical problems to be solved by the present application, the technical solutions and the beneficial effects clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, and are not intended to limit the present application.

[0112] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0113] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0114] In addition, the terms "first", "second", "third", "fourth", "fifth", "sixth", "seventh", "eighth", "ninth", and "tenth" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first", "second", "third", "fourth", "fifth", "sixth", "seventh", "eighth", "ninth", and "tenth" may explicitly or implicitly include one or more of the features. In the description of this application, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0115] In this application, battery cells may include lithium-ion secondary battery cells, lithium-ion primary battery cells, lithium-sulfur battery cells, sodium-lithium-ion battery cells, sodium-ion battery cells, or magnesium-ion battery cells, and the embodiments of this application are not limited thereto. Battery cells may be cylindrical, flat, rectangular, or in other shapes, and the embodiments of this application are not limited thereto.

[0116] The battery mentioned in the embodiments of the present application may include one or more battery cells to provide a single physical module with higher voltage and capacity. When there are multiple battery cells, the multiple battery cells are connected in series, in parallel or in hybrid through a busbar.

[0117] In some embodiments, the battery may be a battery module; when there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module.

[0118] In some embodiments, the battery may be a battery pack, which includes a receiving box and battery cells, wherein the battery cells or battery modules are received in the receiving box.

[0119] A battery cell typically includes an electrode assembly. This assembly includes a positive electrode, a negative electrode, and a separator. During the charge and discharge process of a battery cell, active ions (such as lithium ions) are inserted and removed between the positive and negative electrodes. The separator, located between the positive and negative electrodes, prevents short circuits while allowing the active ions to pass through.

[0120] Optionally, the electrode assembly is a wound structure, wherein the positive electrode sheet and the negative electrode sheet are wound into a wound structure.

[0121] Optionally, the electrode assembly is a laminated structure.

[0122] Optionally, the electrode assembly can be in a cylindrical shape, a flat shape or a multi-prism shape, etc.

[0123] The area energy density requirement of the energy storage device for the energy storage container is getting higher and higher, so in order to improve the electric quantity, the weight of the energy storage container will also increase accordingly. The energy storage container needs to be transported from the production place to the use place by land and / or sea, and there is a transport weight limit for land and sea transportation in general, so there is a contradiction between the improvement of energy density and the weight of the energy storage container.

[0124] Therefore, the embodiments of the present application propose a new technical solution, and the technical solution described in the embodiments of the present application is applicable to the energy storage device and the energy storage system including the energy storage device.

[0125] The energy storage system can be used in energy storage power stations, wind power generation systems, solar power generation systems, mobile power systems or temporary power supply systems, etc. The energy storage power station can store electric energy during the low electricity consumption valley, and provide electric energy for related users or electric equipment during the electricity consumption peak. The wind turbine generator set of the wind power generation system converts the wind energy into electric energy, which is stored by the energy storage device and supplied to the user in time. The solar power generation system can convert solar energy into electric energy, which is stored by the energy storage device and supplied to the user in time. The mobile power system can supply power to related electric equipment in places where the power grid power supply system cannot reach, such as remote mountainous areas and remote wild areas. The temporary power supply system can supply power to users in the case of insufficient power supply. The energy storage system provided by the embodiments of the present application can be any power system that needs to use the energy storage device.

[0181] As an example, the dimension of the box body 111 along the height direction Z is smaller than the dimension of a 20-foot standard container along the height direction Z, that is, the height of the box body 111 is smaller than the height of a 20-foot standard container.

[0182] As an example, the dimension of the box body 111 along the height direction Z is smaller than the dimension of a 30-foot standard container along the height direction Z, that is, the height of the box body 111 is smaller than the height of a 30-foot standard container.

[0183] As an example, the dimension of the box body 111 along the height direction Z is smaller than the dimension of a 40-foot standard container along the height direction Z, that is, the height of the box body 111 is smaller than the height of a 40-foot standard container.

[0184] As an example, the dimension of the box body 111 along the height direction Z is smaller than the dimension of a 45-foot standard container along the height direction Z, that is, the height of the box body 111 is smaller than the height of a 45-foot standard container.

[0185] By adopting the above technical solution, the dimension of the box body 111 along the height direction Z is smaller than the dimension of a standard container along the height direction Z, so that the energy storage container 110 does not exceed the dimension of the height direction Z of a corresponding standard container for ocean or land transportation during transportation. This is conducive to improving the convenience of the energy storage container 110 during transportation, reducing the transportation cost of the energy storage container 110, and thus effectively reducing the use cost of the energy storage device 100.

[0187] m1 energy storage container m out of 110 11 The energy storage containers 110 refer to any m of the m1 energy storage containers 110. 11 Energy storage container 110. For example, the energy storage device 100 has three energy storage containers 110, namely the first energy storage container, the second energy storage container and the third energy storage container. 11 =2, the two energy storage containers 110 can be the first energy storage container and the third energy storage container, or the first energy storage container and the second energy storage container, or the second energy storage container and the third energy storage container.

[0188] It can be m 11Less than m1, the sum of the dimensions of some of the m1 energy storage containers 110 along the height direction Z is equal to the sum of the dimensions of n1 standard containers along the height direction Z. For example, m1=8, m 11 =5, n1=3; wherein, the five energy storage containers 110 can be any five energy storage containers 110 among the eight energy storage containers 110, and the sum of the heights of the five energy storage containers 110 is equal to the height of one standard container.

[0189] It can also be m 11 =m1, the sum of the dimensions of m1 energy storage containers 110 along the height direction Z is equal to the sum of the dimensions of n1 standard containers along the height direction Z. For example, m1=2, m 11 =m1, n1=1, the sum of the heights of the two energy storage containers 110 is equal to the height of one standard container.

[0190] The dimensions of the energy storage container 110 along the height direction Z may be the same, that is, the dimension of the energy storage container 110 along the height direction Z may be m times the sum of the dimensions of n1 standard containers along the height direction Z. 11 One-tenth, that is, m 11 The sum of the dimensions of the energy storage containers 110 along the height direction Z is the sum of the dimensions of n1 standard containers along the height direction Z. Thus, when n1 is 1, m 11 The energy storage containers 110 can form the size of a standard container along the height direction Z, which is convenient for assembly into the size of a standard container for land and sea transportation; when n1 is an integer greater than 1, m 11 The energy storage containers 110 can be combined into n1 standard containers along the height direction Z, and can also be conveniently transported in the size of a standard container. When combined into the size of a standard container for transportation, transportation costs can be greatly reduced.

[0191] Optionally, it can also be m 11 The dimensions of the energy storage containers 110 along the height direction Z are different, but at least m of them need to be set. 11 The sum of the dimensions of the energy storage containers 110 along the height direction Z is the dimensions of n1 standard containers along the height direction Z. 11 The energy storage containers 110 are assembled into one or more standard containers along the height direction Z, which greatly facilitates transportation and reduces transportation costs.

[0192] In the embodiment of the present application, m 11 The sum of the dimensions of n1 energy storage containers 110 along the height direction Z is equal to the sum of the dimensions of n1 standard containers along the height direction Z, which means: 11The sum of the sizes of the m energy storage containers 110 along the height direction Z is approximately equal to the sum of the sizes of the n1 standard containers along the height direction Z. When the size difference between the sum of the sizes of the m energy storage containers 110 along the height direction Z and the sum of the sizes of the n1 standard containers along the height direction Z is within the above-mentioned tolerance range, it can be considered that the sizes are approximately equal. 11 The size difference between the sum of the sizes of the m energy storage containers 110 along the height direction Z and the sum of the sizes of the n1 standard containers along the height direction Z is within the above-mentioned tolerance range, it can be considered that the sizes are approximately equal.

[0193] Optionally, the approximate equal difference value is W, W≤m 11 ×35mm-30mm. For example, m 11 =2, the approximate equal difference value W can be up to 40mm, and when the size difference between the sum of the sizes of the 2 energy storage containers 110 along the height direction Z and the size of the 1 standard container along the height direction Z is within 40mm, i.e. the sum of the sizes of the 2 energy storage containers 110 along the height direction Z is equal to the size of the 1 standard container along the height direction Z. For another example, m 11 =3, the approximate equal difference value W can be up to 75mm, and when the size difference between the sum of the sizes of the 3 energy storage containers 110 along the height direction Z and the size of the 1 standard container along the height direction Z is within 75mm, i.e. the sum of the sizes of the 3 energy storage containers 110 along the height direction Z is equal to the size of the 1 standard container along the height direction Z; or when the size difference between the sum of the sizes of the 3 energy storage containers 110 along the height direction Z and the sum of the sizes of the 2 standard containers along the height direction Z is within 75mm, i.e. the sum of the sizes of the 3 energy storage containers 110 along the height direction Z is equal to the sum of the sizes of the 2 standard containers along the height direction Z.

[0194] Optionally, due to manufacturing errors, the sum of the sizes of the m energy storage containers 110 along the height direction Z can have m 11 manufacturing errors W1, W1≤5mm, i.e. the sum of the sizes of the m energy storage containers 110 along the height direction Z is equal to the sum of the sizes of the n1 standard containers along the height direction Z, or the sum of the sizes of the m energy storage containers 110 along the height direction Z plus m 11 manufacturing errors W1 is equal to the sum of the sizes of the n1 standard containers along the height direction Z. 11 manufacturing errors W1 is equal to the sum of the sizes of the n1 standard containers along the height direction Z. 11 manufacturing errors W1 is equal to the sum of the sizes of the n1 standard containers along the height direction Z. 11 manufacturing errors W1 is equal to the sum of the sizes of the n1 standard containers along the height direction Z.

[0195] For example, m 11 =2, n1=1, the height h of the energy storage container 110 is 1293mm, the height H of the corresponding standard container is 2591mm, n1×H-m 11 ×h=5mm, 5mm 11 ×W1=10mm; therefore, the sum of the sizes of the m energy storage containers 110 along the height direction Z is equal to the sum of the sizes of the n1 standard containers along the height direction Z. 11 manufacturing errors W1 is equal to the sum of the sizes of the n1 standard containers along the height direction Z.

[0196] By adopting the technical scheme, m 11 The size of the m 11 The energy storage container 110 occupies the same space as the n1 standard containers in the stacking process, improves the utilization rate of the space for placing the energy storage container 110, is conducive to fully utilizing the height space in the transportation process, reduces the space waste of the energy storage container 110 in the transportation process, and reduces the transportation cost of the energy storage container 110, thereby further reducing the use cost of the energy storage device 100.

[0197] In some embodiments of the present application, m 11 = 2, n1 = 1.

[0198] The energy storage device 100 can include more than two energy storage containers 110, for example, the energy storage device 100 includes three, five, or eight energy storage containers 110. The energy storage device 100 can also include only two energy storage containers 110.

[0199] By setting the height of the two energy storage containers 110 to be the height of one standard container, when transporting multiple energy storage containers 110 in the energy storage device 100, the adjacent two energy storage containers 110 can be stacked along the height direction Z, so that the two energy storage containers 110 can just occupy the space required by one standard container, improving the space utilization rate of the energy storage container 110, and being conducive to reducing the transportation cost of the energy storage container 110.

[0200] In some embodiments of the present application, m 11 = 3, n1 = 1.

[0201] By setting the height of the three energy storage containers 110 to be the height of one standard container, when transporting multiple energy storage containers 110 in the energy storage device 100, the adjacent three energy storage containers 110 can be stacked along the height direction Z, so that the three energy storage containers 110 can just occupy the space required by one standard container, improving the space utilization rate of the energy storage container 110, and being conducive to reducing the transportation cost of the energy storage container 110.

[0202] In some embodiments of the present application, m 11 = 3, n1 = 2.

[0203] By setting the height of the three energy storage containers 110 as the height of two standard containers, when transporting the plurality of energy storage containers 110 in the energy storage device 100, the adjacent three energy storage containers 110 can be stacked along the height direction Z, so that the three energy storage containers 110 can just occupy the space required by two standard containers, thereby improving the space utilization rate of the energy storage containers 110, and facilitating the reduction of the transportation cost of the energy storage containers 110.

[0204] In some embodiments of the present application, referring to FIG. 3, the energy storage device 100 includes a plurality of energy storage containers 110, and the plurality of energy storage containers 110 are stacked along the height direction Z of the box body 111.

[0205] The number of energy storage containers 110 in the energy storage device 100 can be any number greater than 2, for example, the energy storage device 100 includes two energy storage containers 110, and during the assembly of the energy storage device 100, the two energy storage containers 110 can be stacked along the height direction Z; for another example, the energy storage device 100 includes three energy storage containers 110, and during the assembly of the energy storage device 100, the three energy storage containers 110 can be stacked along the height direction Z.

[0206] In some embodiments, when the number of energy storage containers 110 in the energy storage device 100 is too large, it is easy to cause damage to the box body 111 of the bottommost energy storage container 110, so the sum of the heights of the energy storage containers 110 stacked along the height direction Z is less than or equal to the sum of the heights of eight standard containers stacked.

[0207] By adopting the above technical solution, under the condition that the occupied area of the energy storage device 100 is the same, more energy storage containers 110 can be configured, thereby improving the energy density of the energy storage device 100, and effectively improving the performance of the energy storage device 100.

[0208] In some embodiments of the present application, referring to FIG. 3, the plurality of energy storage containers 110 include a first energy storage container and a second energy storage container, the first energy storage container is located above the second energy storage container, the bottom of the box body 111 of the first energy storage container is provided with a first connecting portion 1113, the top of the box body 111 of the second energy storage container is provided with a second connecting portion 1114, and the first connecting portion 1113 is connected with the second connecting portion 1114.

[0209] The first connecting portion 1113 and the second connecting portion 1114 cooperate to form at least part of a first connecting structure for connecting two adjacent energy storage containers 110 along the height direction Z, and the connection mode of the first connecting portion 1113 and the second connecting portion 1114 can be, but is not limited to, welding, clamping, threaded connection, etc.

[0210] The two energy storage containers 110 in the transportation are connected and fixed by the first connecting structure in the height direction Z. Then, the sum of the heights of m 11 energy storage containers 110 and the heights of the first connecting structures between the energy storage containers 110 is equal to the sum of the heights of n1 standard containers. That is, when the first connecting structure is arranged, the height of each of the m 11 energy storage containers 110 is equal to the sum of the height of the energy storage container 110 itself and the height of the first connecting structure connected to the energy storage container 110. Because the first connecting structure for connecting the energy storage containers 110 in the height direction Z also occupies the height of the energy storage container 110 to some extent.

[0211] For example, when the m 11 energy storage containers 110 are connected and fixed by the first connecting structure for transportation, the sum of the heights of the m 11 energy storage containers 110 and the sum of the heights of the first connecting structures are equal to the sum of the heights of n1 standard containers. 11 Optionally, the number of the first connecting structures in the m 11 energy storage containers 110 can be less than m 11 -1. When the m 11 energy storage containers 110 are assembled into the size of the standard container, the sum of the heights of the m 11 energy storage containers 110 and the sum of the heights of the actual first connecting structures is equal to the sum of the heights of n1 standard containers.

[0212] For example, the height of the first connecting structure in the height direction Z is W2, and W2≤30 mm. For example, m 11 =3, n1=2, the height h of the energy storage container 110 is 845 mm, the height H of the corresponding standard container is 2591 mm, n1×H-m 11 ×h=56 mm, 56 mm 11 ×W1+(m 11 -1)×W2=75 mm; therefore, the sum of the heights of the m 11 energy storage containers 110 is equal to the sum of the heights of n1 standard containers. W=m 11 ×W1+(m 11 -1)×W2.

[0213] Therefore, when the energy storage device 100 is transported by using the first connecting structure, the energy storage containers 110 constituting the energy storage device 100 do not need the first connecting structure. The sum of the heights of m 11The sum of the sizes of the energy storage containers 110 along the height direction Z is equal to the sum of the sizes of n1 standard containers along the height direction Z minus the sum of the heights of the first connecting structures used. 11 The sum of the sizes of the energy storage containers 110 along the height direction Z is equal to the sum of the sizes of n1 standard containers along the height direction Z minus the sum of the heights of the first connecting structures used.

[0214] As an example, the first connecting part 1113 can be a first locking hole, and the second connecting part 1114 can be a first locking member, which is locked and connected in the first locking hole.

[0215] As an example, the first connecting part 1113 can be a second locking member, and the second connecting part 1114 can be a second locking hole, which is locked and connected in the second locking hole.

[0216] As an example, the first connecting part 1113 can be a first locking hole, and the second connecting part 1114 can be a second locking hole, and the first connecting structure further comprises a first connecting piece, one end of the first connecting piece is connected in the first locking hole along the height direction Z of the container body 111, and the other end of the first connecting piece is connected in the second locking hole along the height direction Z of the container body 111.

[0217] By adopting the above technical solutions, the structure of the stacked multiple energy storage containers 110 becomes more stable, thereby effectively improving the transportation safety of the energy storage containers 110 and the use safety of the energy storage device 100.

[0218] In some embodiments of the present application, the multiple energy storage containers 110 include a first energy storage container and a second energy storage container, the first energy storage container is located above the second energy storage container, the bottom of the container body 111 of the first energy storage container is provided with a first limiting part, the top of the container body 111 of the second energy storage container is provided with a second limiting part, and the first limiting part cooperates with the second limiting part to limit the relative position of the first energy storage container and the second energy storage container along a direction perpendicular to the height direction Z of the container body 111.

[0219] The first limiting part and the second limiting part cooperate to form at least part of the limiting structure for limiting the relative position of the two adjacent energy storage containers 110 along the height direction Z.

[0220] As an example, the first limiting part can be a first limiting hole, and the second limiting part can be a first limiting member, which is inserted into the first limiting hole along the height direction Z of the container body 111.

[0221] As an example, the first limiting part can be a second limiting piece, and the second limiting part can be a second limiting hole. The second limiting piece is inserted into the second limiting hole along the height direction Z of the box body 111.

[0222] As an example, the first limiting part can be a first limiting hole, and the second limiting part can be a second limiting hole. The above limiting structure further includes a limiting piece. One end of the limiting piece is inserted into the first limiting hole along the height direction Z of the box body 111, and the other end of the limiting piece is inserted into the second limiting hole along the height direction Z of the box body 111.

[0223] By adopting the above technical solution, the relative positions of the two energy storage containers 110 in the direction perpendicular to the height direction Z of the box body 111 are effectively limited, thereby effectively reducing the risk of relative movement of adjacent two energy storage containers 110.

[0224] In some embodiments of the present application, referring to FIG. 3, the second direction is the length direction X of the box body 111, and the size of the box body 111 along the width direction Y is consistent with the size of a standard container along the width direction Y.

[0225] The size of the box body 111 along the width direction Y is consistent with the size of a standard container along the width direction Y, which does not mean that the width of the box body 111 is exactly equal to the width of a standard container. Within the allowable error range, there can be a certain error. As an example, referring to GB / T1413-2008 and GB / T 1413-2023, the difference between the size of the box body 111 along the width direction Y and the size of a standard container along the width direction Y is within ±5mm.

[0226] It should be noted that in actual application, the size of the box body 111 along the length direction X, the size of the box body 111 along the height direction Z, and the size of the box body 111 along the width direction Y can correspond to the size of a standard container of the same standard size, or can correspond to the size of a standard container of different standard sizes.

[0227] In some embodiments, the size of the box body 111 along the length direction X is smaller than the size of a standard container of a standard size along the length direction X, the size of the box body 111 along the height direction Z is smaller than the size of a standard container of another standard size along the height direction Z, and the size of the box body 111 along the width direction Y is consistent with the size of a standard container of another standard size along the width direction Y.

[0228] As an example, the box 111 has a length in the length direction X that is less than the length in the length direction X of a 10 ft standard container, a height in the height direction Z that is less than the height in the height direction Z of a 20 ft standard container, and a width in the width direction Y that is the same as the width in the width direction Y of a 30 ft standard container.

[0229] In other embodiments, the box 111 has a length in the length direction X and a height in the height direction Z that are less than the length in the length direction X and the height in the height direction Z of a standard container of one standard size, and a width in the width direction Y that is the same as the width in the width direction Y of a standard container of another standard size.

[0230] As an example, the box 111 has a length in the length direction X and a height in the height direction Z that are less than the length in the length direction X and the height in the height direction Z of a 20 ft standard container, and a width in the width direction Y that is the same as the width in the width direction Y of a 30 ft standard container.

[0231] In yet other embodiments, the box 111 has a length in the length direction X and a height in the height direction Z that are less than the length in the length direction X and the height in the height direction Z of a standard container of one standard size, and a width in the width direction Y that is the same as the width in the width direction Y of a standard container of that standard size.

[0232] As an example, the box 111 has a length in the length direction X and a height in the height direction Z that are less than the length in the length direction X and the height in the height direction Z of a 20 ft standard container, and a width in the width direction Y that is the same as the width in the width direction Y of a 20 ft standard container.

[0233] In still other embodiments, the box 111 has a length in the length direction X that is less than the length in the length direction X of a standard container of one standard size, a width in the width direction Y that is the same as the width in the width direction Y of a standard container of that standard size, and a height in the height direction Z that is less than the height in the height direction Z of a standard container of another standard size.

[0234] As an example, the size of the box 111 along the length direction X is less than the size of a 20-foot standard container along the length direction X, i.e., the length of the box 111 is less than the length of a 20-foot standard container, the size of the box 111 along the width direction Y is the same as the size of a 20-foot standard container along the width direction Y, i.e., the width of the box 111 is the same as the width of a 20-foot standard container, and the size of the box 111 along the height direction Z is less than the size of a 30-foot standard container along the height direction Z, i.e., the height of the box 111 is less than the height of a 30-foot standard container.

[0235] In some other embodiments, the size of the box 111 along the height direction Z is less than the size of a standard container of a standard size along the height direction Z, the size of the box 111 along the width direction Y is the same as the size of the standard container of the standard size along the width direction Y, and the size of the box 111 along the length direction X is less than the size of a standard container of another standard size along the length direction X.

[0236] As an example, the size of the box 111 along the height direction Z is less than the size of a 20-foot standard container along the height direction Z, i.e., the height of the box 111 is less than the height of a 20-foot standard container, the size of the box 111 along the width direction Y is the same as the size of a 20-foot standard container along the width direction Y, i.e., the width of the box 111 is the same as the width of a 20-foot standard container, and the size of the box 111 along the length direction X is less than the size of a 30-foot standard container along the length direction X, i.e., the length of the box 111 is less than the length of a 30-foot standard container.

[0237] By using the above technical solutions, the size of the energy storage container 110 along the length direction X does not exceed the size of a standard container for marine transportation or land transportation, which is beneficial to improve the convenience of the energy storage container 110 during transportation and reduce the transportation cost of the energy storage container 110, thereby effectively reducing the use cost of the energy storage device 100.

[0238] In some embodiments of the present application, referring to FIG. 3, the energy storage device 100 includes a plurality of energy storage containers 110, m2 energy storage containers 110 in the plurality of energy storage containers 110 are arranged in a row along the length direction X of the box 111, and m3 rows of energy storage containers 110 are stacked along the height direction Z of the box 111, where m2 and m3 are positive integers greater than or equal to 2.

[0239] In some embodiments, the energy storage device 100 includes at least 4 energy storage containers 110, and the number of energy storage containers 110 in the energy storage device 100 is an integer multiple of 2.

[0240] As an example, the energy storage device 100 includes four energy storage containers 110. During assembly of the energy storage device 100, every two energy storage containers 110 can be arranged into a row along the length direction X of the box body 111, and then the two rows of energy storage containers 110 can be stacked along the height direction Z of the box body 111.

[0241] As an example, the energy storage device 100 includes six energy storage containers 110. During assembly of the energy storage device 100, every two energy storage containers 110 can be arranged into a row along the length direction X of the box body 111, and then three rows of energy storage containers 110 can be stacked along the height direction Z of the box body 111.

[0242] By adopting the above technical solution, more energy storage containers 110 can be configured when the footprint of the energy storage device 100 remains the same, thereby increasing the energy density of the energy storage device 100 and effectively improving the performance of the energy storage device 100.

[0243] In some embodiments of the present application, m of the m2 energy storage containers 110 21 The sum of the dimensions of the energy storage containers 110 along the length direction X of the box body 111 is equal to the sum of the dimensions of n2 standard containers along the length direction X, and n2 is less than m 21 A positive integer, m3 of the energy storage container 110 31 The sum of the dimensions of the energy storage container 110 along the height direction Z of the box body 111 is equal to the sum of the dimensions of n3 standard containers along the height direction Z, where n3 is less than m 31 A positive integer.

[0244] m2 energy storage container m in 110 21 The energy storage container 110 refers to any m2 of the energy storage containers 110. 21 Energy storage containers 110. For example, the energy storage device 100 has four energy storage containers 110, namely the first energy storage container, the second energy storage container, the third energy storage container and the fourth energy storage container. 21 =2, the two energy storage containers 110 can be the first energy storage container and the third energy storage container, or the first energy storage container and the second energy storage container, or the second energy storage container and the fourth energy storage container.

[0245] It can be m 21 Less than m2, the sum of the dimensions of some of the m2 energy storage containers 110 along the length direction X is equal to the sum of the dimensions of n2 standard containers along the length direction X. For example, m2=8, m 21=5, n2=3; wherein, the five energy storage containers 110 can be any five energy storage containers 110 among the eight energy storage containers 110, and the sum of the lengths of the five energy storage containers 110 is equal to the length of one standard container.

[0246] It can also be m 21 = m2, the sum of the dimensions of m2 energy storage containers 110 along the length direction X is equal to the sum of the dimensions of n2 standard containers along the length direction X. For example, m2 = 2, m 21 =m2, n2=1, the sum of the lengths of the two energy storage containers 110 is equal to the length of one standard container.

[0247] The dimensions of the energy storage container 110 along the length direction X may be the same, that is, the dimension of the energy storage container 110 along the length direction X may be m times the sum of the dimensions of n2 standard containers along the length direction X. 21 One-tenth, that is, m 21 The sum of the dimensions of the energy storage containers 110 along the length direction X is the sum of the dimensions of n2 standard containers along the length direction X. Thus, when n2 is 1, m 21 The energy storage containers 110 can form a standard container along the length direction X, which is convenient for assembly into the size of a standard container for land and sea transportation; when n2 is an integer greater than 1, m 21 The energy storage containers 110 can be combined into n2 standard containers along the length direction X, and can also be conveniently transported in the size of standard containers. When transported in the size of standard containers, transportation costs can be greatly reduced.

[0248] Optionally, it can also be m 21 The dimensions of the energy storage containers 110 along the length direction X are different, but at least m of them need to be set. 21 The sum of the dimensions of the energy storage containers 110 along the length direction X is the dimensions of n2 standard containers along the length direction X. 21 The energy storage containers 110 are assembled into one or more standard containers along the length direction X to greatly facilitate transportation and reduce transportation costs.

[0249] In the embodiment of the present application, m 21 The sum of the dimensions of n energy storage containers 110 along the length direction X is equal to the sum of the dimensions of n2 standard containers along the length direction X, which means: 21 The sum of the dimensions of the energy storage containers 110 along the length direction X is approximately equal to the sum of the dimensions of n2 standard containers along the length direction X. 21When the difference between the sum of the dimensions of n energy storage containers 110 along the length direction X and the sum of the dimensions of n2 standard containers along the length direction X is within the above tolerance range, they can be considered to be approximately equal in size.

[0250] Optionally, due to manufacturing errors, m 21 The sum of the dimensions of the energy storage containers 110 along the length direction X may be m 21 A manufacturing error W3, W3 ≤ 5mm, that is, m 21 The sum of the dimensions of the energy storage containers 110 along the length direction X is equal to the sum of the dimensions of n2 standard containers along the length direction X, which can also be m 21 The sum of the dimensions of the energy storage containers 110 along the length direction X plus m 21 W3 is equal to the sum of the dimensions of n2 standard containers along the length direction X.

[0251] As an example, m 21 =2, n2=1, the length l of the energy storage container 110 is 3027 mm, the length L of the corresponding standard container is 6058 mm, n2×Lm 21 ×l=4mm,4mm<m 21 ×W3=10mm; therefore, m 21 The sum of the dimensions of n energy storage containers 110 along the length direction X is equal to the sum of the dimensions of n2 standard containers along the length direction X.

[0252] m3 row energy storage container 110 m 31 The row energy storage container 110 refers to any m3 row energy storage container 110 31 For example, the energy storage device 100 includes 8 energy storage containers 110, with every 2 energy storage containers 110 arranged in a row along the length direction X, and 4 rows of energy storage containers 110 stacked along the height direction Z. 31 =2, the two rows of energy storage containers 110 can be the first row and the second row, the first row and the third row, or the second row and the fourth row.

[0253] It can be m 31 Less than m3, the sum of the dimensions of several rows of energy storage containers 110 in the m3 row energy storage container 110 along the height direction Z is equal to the sum of the dimensions of n3 standard containers along the height direction Z. For example, m3=8, m 31 =5, n3=3; wherein, the 5 rows of energy storage containers 110 can be any 5 rows of energy storage containers 110 among the 8 rows of energy storage containers 110, and the sum of the heights of the 5 rows of energy storage containers 110 is equal to the height of one standard container.

[0254] It can also be m 31= m3, the sum of the dimensions of m3 energy storage containers 110 along the height direction Z is equal to the sum of the dimensions of n3 standard containers along the height direction Z. For example, m3 = 2, m 31 =m3, n3=1, the sum of the heights of the two rows of energy storage containers 110 is equal to the height of one standard container.

[0255] It can be m 31 The dimensions of the energy storage containers 110 in the row along the height direction Z are the same, that is, the dimension of one row of energy storage containers 110 in the height direction Z can be m times the sum of the dimensions of n3 standard containers in the height direction Z. 31 One-tenth, that is, m 31 The sum of the dimensions of the row energy storage container 110 along the height direction Z is the sum of the dimensions of n3 standard containers along the height direction Z. Thus, when n3 is 1, m 31 The energy storage container 110 can form the size of a standard container along the height direction Z, which is convenient for assembly into the size of a standard container for land and sea transportation; when n3 is an integer greater than 1, m 31 The row energy storage container 110 can be formed into n3 standard containers along the height direction Z, and can also be conveniently transported in the size of a standard container. When transported in the size of a standard container, the transportation cost can be greatly reduced.

[0256] Optionally, it can also be m 31 The dimensions of the energy storage container 110 along the height direction Z are different, but at least m 31 The sum of the dimensions of the energy storage container 110 along the height direction Z is the dimensions of n3 standard containers along the height direction Z. 31 The energy storage container 110 is assembled into one or more standard containers along the height direction Z to greatly facilitate transportation and reduce transportation costs.

[0257] In the embodiment of the present application, m 31 The sum of the dimensions of the row energy storage container 110 along the height direction Z is equal to the sum of the dimensions of n3 standard containers along the height direction Z, which means: m 31 The sum of the dimensions of the row energy storage container 110 along the height direction Z is approximately equal to the sum of the dimensions of n3 standard containers along the height direction Z. 31 When the difference between the sum of the dimensions of the row energy storage container 110 along the height direction Z and the sum of the dimensions of n3 standard containers along the height direction Z is within the above tolerance range, they can be considered to be approximately equal in size.

[0258] Optionally, due to manufacturing errors, m 31 The sum of the dimensions of the energy storage container 110 along the height direction Z may be m.31 a manufacturing error W1, W1≤5mm, i.e. m 31 The sum of the dimensions of the energy storage containers 110 along the height direction Z is equal to the sum of the dimensions of n3 standard containers along the height direction Z, or m 31 The sum of the dimensions of the energy storage containers 110 along the height direction Z plus m 31 W1 is equal to the sum of the dimensions of n3 standard containers along the height direction Z.

[0259] For example, m 31 =2, n3=1, the height h of the energy storage container 110 is 1293mm, the height H of the corresponding standard container is 2591mm, n3xH-m 31 xh=5mm, 5mm 31 xW1=10mm; therefore, m 31 The sum of the dimensions of the energy storage containers 110 along the height direction Z is equal to the sum of the dimensions of n3 standard containers along the height direction Z.

[0273] In some embodiments of the present application, m 21 = 3, n2 = 2, m 31 = 2, n3 = 1.

[0274] By adopting the above technical solutions, when transporting the plurality of energy storage containers 110 in the energy storage device 100, not only a certain number of energy storage containers 110 can be arranged and disposed along the length direction X of the box body 111, but also a certain number of energy storage containers 110 can be stacked and disposed along the height direction Z of the box body 111, so that the certain number of energy storage containers 110 can just occupy the space required to be occupied by at least one standard container, thereby improving the space utilization rate of the energy storage containers 110, and being conducive to reducing the transportation cost of the energy storage containers 110.

[0275] In some embodiments of the present application, m 21 = 3, n2 = 2, m 31 = 3, n3 = 1.

[0276] By adopting the above technical solutions, when transporting the plurality of energy storage containers 110 in the energy storage device 100, not only a certain number of energy storage containers 110 can be arranged along the length direction X of the box body 111, but also a certain number of energy storage containers 110 can be stacked along the height direction Z of the box body 111, so that the certain number of energy storage containers 110 can just occupy the space required by at least one standard container, thereby improving the space utilization rate of the energy storage containers 110, and being conducive to reducing the transportation cost of the energy storage containers 110.

[0277] In some embodiments of the present application, m 21 = 3, n2= 2, m 31 = 3, n3= 2.

[0278] By adopting the above technical solutions, when transporting the plurality of energy storage containers 110 in the energy storage device 100, not only a certain number of energy storage containers 110 can be arranged along the length direction X of the box body 111, but also a certain number of energy storage containers 110 can be stacked along the height direction Z of the box body 111, so that the certain number of energy storage containers 110 can just occupy the space required by at least one standard container, thereby improving the space utilization rate of the energy storage containers 110, and being conducive to reducing the transportation cost of the energy storage containers 110.

[0279] In some embodiments of the present application, referring to FIG. 3, the plurality of energy storage containers 110 include a third energy storage container and a fourth energy storage container arranged along the length direction X of the box body 111, the third energy storage container is provided with a third connecting portion 1115 facing one side of the fourth energy storage container, the fourth energy storage container is provided with a fourth connecting portion 1116 facing one side of the third energy storage container, and the third connecting portion 1115 is connected with the fourth connecting portion 1116.

[0280] The third connecting portion 1115 and the fourth connecting portion 1116 cooperate to form at least part of a second connecting structure for connecting two energy storage containers 110 adjacent along the length direction X, and the connection mode of the third connecting portion 1115 and the fourth connecting portion 1116 can be, but is not limited to, welding, clamping, threaded connection, etc.

[0281] The two energy storage containers 110 assembled and transported along the length direction X are connected and fixed through the above-mentioned second connecting structure, so that m 21 The energy storage containers 110 along the length direction X form the size of n2 standard containers along the length direction X, and also include the size of the second connecting structure between each other along the length direction X. That is, when the second connecting structure is provided, m 21The length of some of the energy storage containers 110 along the length direction X may be the sum of its own length and the length of the second connecting structure connected thereto along the length direction X. This is because the second connecting structure connecting the energy storage containers 110 along the length direction X also occupies the length of the energy storage container 110 to a certain extent.

[0282] For example, when m 21 When the energy storage containers 110 are assembled and fixed by the second connection structure for transportation, m 21 The sum of the dimensions of the energy storage containers 110 along the length direction X and m 21 The sum of the dimensions of the -1 second connecting structures along the length direction X is equal to the sum of the dimensions of n2 standard containers along the length direction X. Optionally, at m 21 The number of second connection structures in an energy storage container 110 may be less than m 21 -1, then when these energy storage containers 110 are assembled into the size of a standard container, including m 21 The sum of the dimensions of the energy storage containers 110 along the length direction X and the sum of the dimensions of the actual second connecting structure along the length direction X.

[0283] For example, the size of the second connection structure along the length direction X is W4, W4≤30mm. As an example, m 21 =3, n2=2, the length l of the energy storage container 110 is 4020 mm, the length L of the corresponding standard container is 6058 mm, n2×Lm 21 ×l=56mm,56mm<m 21 ×W3+(m 21 -1)×W4=75mm; therefore, m 21 The sum of the dimensions of n energy storage containers 110 along the length direction X is equal to the sum of the dimensions of n2 standard containers along the length direction X.

[0284] Therefore, when the energy storage device 100 of the embodiment of the present application uses the second connection structure during transportation, and the energy storage containers 110 constituting the energy storage device 100 do not need the second connection structure, "m 21 The sum of the dimensions of the energy storage containers 110 along the length direction X of the box body 111 is equal to the sum of the dimensions of n2 standard containers along the length direction X” should be understood to include the dimension of the second connection structure used along the length direction X. That is, m 21 The sum of the dimensions of the energy storage containers 110 along the length direction X is equal to the sum of the dimensions of n2 standard containers along the length direction X minus the sum of the dimensions of the second connecting structure used along the length direction X. This situation also falls within the scope of the embodiments of claims 10 to 12 of the present application.

[0285] As an example, the third connecting part 1115 can be a third locking hole, and the fourth connecting part 1116 can be a third locking piece, which is locked and connected in the third locking hole.

[0286] As an example, the third connecting part 1115 can be a fourth locking piece, and the fourth connecting part 1116 can be a fourth locking hole, and the fourth locking piece is locked and connected in the fourth locking hole.

[0287] As an example, the third connecting part 1115 can be a third locking hole, and the fourth connecting part 1116 can be a fourth locking hole, and the second connecting structure further includes a second connecting piece, one end of the second connecting piece is connected to the third locking hole along the length direction X of the box body 111, and the other end of the second connecting piece is connected to the third locking hole along the length direction X of the box body 111.

[0288] By adopting the above technical solution, the structure of the plurality of energy storage containers 110 after stacking can be made more stable, thereby effectively improving the transportation safety of the energy storage container 110 and the use safety of the energy storage device 100.

[0289] In some embodiments of the present application, referring to FIG. 6, the second direction is the width direction Y of the box body 111, and the size of the box body 111 along the length direction X is consistent with the size of the standard container along the length direction X.

[0290] The size of the box body 111 along the length direction X is consistent with the size of the standard container along the length direction X, which does not mean that the length of the box body 111 is exactly equal to the length of the standard container, but within the error allowable range, there can be a certain error. As an example, referring to GB / T1413-2008, GB / T 1413-2023, the difference between the size of the box body 111 along the length direction X and the size of the standard container along the length direction X is within ±10mm.

[0291] It should be noted that in actual application, the size of the box body 111 along the length direction X, the size of the box body 111 along the height direction Z and the size of the box body 111 along the width direction Y can correspond to the size of the standard container of the same standard size, or can correspond to the size of the standard container of different standard sizes.

[0292] In some embodiments, the size of the box body 111 along the width direction Y is smaller than the size of the standard container of one standard size along the width direction Y, the size of the box body 111 along the height direction Z is smaller than the size of the standard container of another standard size along the height direction Z, and the size of the box body 111 along the length direction X is consistent with the size of the standard container of another standard size along the length direction X.

[0293] As an example, the box 111 has a size along the width direction Y that is smaller than a size along the width direction Y of a standard container of a standard size of 10 feet, i.e. the width of the box 111 is smaller than the width of a standard container of 10 feet, a size along the height direction Z that is smaller than a size along the height direction Z of a standard container of 20 feet, i.e. the height of the box 111 is smaller than the height of a standard container of 20 feet, and a size along the length direction X that is identical to a size along the length direction X of a standard container of 30 feet, i.e. the length of the box 111 is identical to the length of a standard container of 30 feet.

[0294] In other embodiments, the box 111 has a size along the width direction Y and a size along the height direction Z that are smaller than a size along the width direction Y and a size along the height direction Z of a standard container of a standard size, and a size along the length direction X that is identical to a size along the length direction X of a standard container of another standard size.

[0295] As an example, the box 111 has a size along the width direction Y and a size along the height direction Z that are smaller than a size along the width direction Y and a size along the height direction Z of a standard container of 20 feet, i.e. the width of the box 111 is smaller than the width of a standard container of 20 feet and the height of the box 111 is smaller than the height of a standard container of 20 feet, and a size along the length direction X that is identical to a size along the length direction X of a standard container of 30 feet, i.e. the length of the box 111 is identical to the length of a standard container of 30 feet.

[0296] In yet other embodiments, the box 111 has a size along the width direction Y and a size along the height direction Z that are smaller than a size along the width direction Y and a size along the height direction Z of a standard container of a standard size, and a size along the length direction X that is identical to a size along the length direction X of a standard container of the standard size.

[0297] As an example, the box 111 has a size along the width direction Y and a size along the height direction Z that are smaller than a size along the width direction Y and a size along the height direction Z of a standard container of 20 feet, i.e. the width of the box 111 is smaller than the width of a standard container of 20 feet and the height of the box 111 is smaller than the height of a standard container of 20 feet, and a size along the length direction X that is identical to a size along the length direction X of a standard container of 20 feet, i.e. the length of the box 111 is identical to the length of a standard container of 20 feet.

[0298] In still other embodiments, the box 111 has a size along the width direction Y that is smaller than a size along the width direction Y of a standard container of a standard size, a size along the length direction X that is identical to a size along the length direction X of a standard container of the standard size, and a size along the height direction Z that is smaller than a size along the height direction Z of a standard container of another standard size.

[0299] For example, the size of the box 111 along the width direction Y is less than the size of a 20-foot standard container along the width direction Y, i.e., the width of the box 111 is less than the width of a 20-foot standard container, the size of the box 111 along the length direction X is the same as the size of a 20-foot standard container along the length direction X, i.e., the length of the box 111 is the same as the length of a 20-foot standard container, and the size of the box 111 along the height direction Z is less than the size of a 30-foot standard container along the height direction Z, i.e., the height of the box 111 is less than the height of a 30-foot standard container.

[0300] In some embodiments, the size of the box 111 along the height direction Z is less than the size of a standard container of a standard size along the height direction Z, the size of the box 111 along the length direction X is the same as the size of the standard container of the standard size along the length direction X, and the size of the box 111 along the width direction Y is less than the size of a standard container of another standard size along the width direction Y.

[0301] For example, the size of the box 111 along the height direction Z is less than the size of a 20-foot standard container along the height direction Z, i.e., the height of the box 111 is less than the height of a 20-foot standard container, the size of the box 111 along the length direction X is the same as the size of a 20-foot standard container along the length direction X, i.e., the length of the box 111 is the same as the length of a 20-foot standard container, and the size of the box 111 along the width direction Y is less than the size of a 30-foot standard container along the width direction Y, i.e., the width of the box 111 is less than the width of a 30-foot standard container.

[0302] By using the above technical solutions, the size of the energy storage container 110 along the width direction Y does not exceed the size of a standard container for marine transportation or land transportation, which is beneficial to improve the convenience of the energy storage container 110 during transportation and further reduce the transportation cost of the energy storage container 110, thereby further reducing the use cost of the energy storage device 100.

[0303] In some embodiments of the present application, referring to FIG. 6, the energy storage device 100 includes a plurality of energy storage containers 110, m4 energy storage containers 110 in the plurality of energy storage containers 110 are arranged in a column along the width direction Y of the box 111, and m5 columns of energy storage containers 110 are stacked along the height direction Z of the box 111, where m4 and m5 are positive integers greater than or equal to 2.

[0304] In some embodiments, the energy storage device 100 includes at least 4 energy storage containers 110, and the number of energy storage containers 110 in the energy storage device 100 is an integer multiple of 2.

[0305] As an example, the energy storage device 100 includes four energy storage containers 110. During the assembly of the energy storage device 100, every two energy storage containers 110 can be arranged into a row along the width direction Y of the box body 111, and then the two rows of energy storage containers 110 can be stacked along the height direction Z of the box body 111.

[0306] As an example, the energy storage device 100 includes six energy storage containers 110. During assembly of the energy storage device 100, every two energy storage containers 110 can be arranged into a row along the width direction Y of the box body 111, and then three rows of energy storage containers 110 can be stacked along the height direction Z of the box body 111.

[0307] By adopting the above technical solution, more energy storage containers 110 can be configured when the footprint of the energy storage device 100 remains the same, thereby increasing the energy density of the energy storage device 100 and effectively improving the performance of the energy storage device 100.

[0308] In some embodiments of the present application, please refer to FIG6 , m of the m4 energy storage containers 110 41 The sum of the dimensions of the energy storage containers 110 along the width direction Y of the box body 111 is equal to the sum of the dimensions of n4 standard containers along the width direction Y, where n4 is less than m 41 A positive integer, m5 in the energy storage container 110 51 The sum of the dimensions of the energy storage container 110 in the height direction Z of the box body 111 is equal to the sum of the dimensions of n5 standard containers in the height direction Z, where n5 is less than m 51 A positive integer.

[0309] m4 energy storage containers m out of 110 41 The energy storage containers 110 refer to any m of the m4 energy storage containers 110. 41 Energy storage containers 110. For example, the energy storage device 100 has four energy storage containers 110, namely the first energy storage container, the second energy storage container, the third energy storage container and the fourth energy storage container. 41 =2, the two energy storage containers 110 can be the first energy storage container and the third energy storage container, or the first energy storage container and the second energy storage container, or the second energy storage container and the fourth energy storage container.

[0310] It can be m 41 Less than m4, the sum of the dimensions of some of the m4 energy storage containers 110 along the width direction Y is equal to the sum of the dimensions of n4 standard containers along the width direction Y. For example, m4=8, m 41= 5, n4= 3; wherein, the 5 energy storage containers 110 can be any 5 energy storage containers 110 of the 8 energy storage containers 110, and the sum of the widths of the 5 energy storage containers 110 is equal to the width of one standard container.

[0311] Also, m 41 = m4, the sum of the dimensions of the m4 energy storage containers 110 along the width direction Y is equal to the sum of the dimensions of the n4 standard containers along the width direction Y. For example, m4= 2, m 41 = m4, n4= 1, the sum of the widths of the 2 energy storage containers 110 is equal to the width of one standard container.

[0312] The dimensions of the energy storage containers 110 along the width direction Y can be the same, that is, the dimensions of the energy storage containers 110 along the width direction Y can be m 41 times the sum of the dimensions of the n4 standard containers along the width direction Y. That is, m 41 = m4, the sum of the dimensions of the m4 energy storage containers 110 along the width direction Y is equal to the sum of the dimensions of the n4 standard containers along the width direction Y. For example, m4= 2, m 41 = m4, n4= 1, the sum of the widths of the 2 energy storage containers 110 is equal to the width of one standard container. 41 = m4, n4= 1, the sum of the widths of the 2 energy storage containers 110 is equal to the width of one standard container.

[0313] Optionally, the dimensions of the m 41 energy storage containers 110 along the width direction Y can be different, but at least the sum of the dimensions of the m 41 energy storage containers 110 along the width direction Y is equal to the sum of the dimensions of the n4 standard containers along the width direction Y. In this way, the m 41 energy storage containers 110 with different dimensions along the width direction Y can be assembled into the dimensions of one or more standard containers along the width direction Y, so as to greatly facilitate transportation and reduce transportation costs.

[0314] In the embodiments of the present application, the sum of the dimensions of the m 41 energy storage containers 110 along the width direction Y is equal to the sum of the dimensions of the n4 standard containers along the width direction Y means that the sum of the dimensions of the m 41 energy storage containers 110 along the width direction Y is approximately equal to the sum of the dimensions of the n4 standard containers along the width direction Y. When m 41When the difference between the sum of the dimensions of n energy storage containers 110 along the width direction Y and the sum of the dimensions of n4 standard containers along the width direction Y is within the above tolerance range, they can be considered to be approximately equal in size.

[0315] Optionally, due to manufacturing errors, m 41 The sum of the dimensions of the energy storage containers 110 along the width direction Y may be m 41 A manufacturing error W5, W5 ≤ 5mm, that is, m 41 The sum of the dimensions of the energy storage containers 110 along the width direction Y is equal to the sum of the dimensions of n4 standard containers along the width direction Y, which can also be m 41 The sum of the dimensions of the energy storage containers 110 along the width direction Y plus m 41 W5 is equal to the sum of the dimensions of n4 standard containers along the width direction Y.

[0316] As an example, m 41 =2, n4=1, the width k of the energy storage container 110 is 1215 mm, the corresponding width K of the standard container is 2438 mm, n4×Km 41 ×k=8mm,8mm<m 41 ×W5=10mm; therefore, m 41 The sum of the dimensions of n4 energy storage containers 110 along the width direction Y is equal to the sum of the dimensions of n4 standard containers along the width direction Y.

[0317] m5 row of energy storage containers 110 m 51 The energy storage container row 110 refers to any m5 energy storage container row 110. 51 For example, the energy storage device 100 includes 8 energy storage containers 110, with every 2 energy storage containers 110 arranged in a row along the width direction Y, and 4 rows of energy storage containers 110 stacked along the height direction Z. 51 =2, the two rows of energy storage containers 110 can be the first row and the second row, the first row and the third row, or the second row and the fourth row.

[0318] It can be m 51 Less than m5, the sum of the dimensions of several rows of energy storage containers 110 in the m5 row of energy storage containers 110 along the height direction Z is equal to the sum of the dimensions of n5 standard containers along the height direction Z. For example, m5=8, m 51 =5, n5=3; wherein, the 5 rows of energy storage containers 110 can be any 5 rows of energy storage containers 110 among the 8 rows of energy storage containers 110, and the sum of the heights of the 5 rows of energy storage containers 110 is equal to the height of one standard container.

[0319] It can also be m 51m5, the sum of the sizes of the m5 energy storage containers 110 along the height direction Z is equal to the sum of the sizes of the n5 standard containers along the height direction Z. For example, m5 = 2, m 51 m5, n5 = 1, the sum of the heights of the 2 columns of energy storage containers 110 is equal to the height of 1 standard container.

[0320] m5 can be equal to 1 51 The sizes of the m5 columns of energy storage containers 110 along the height direction Z are the same, that is, the size of 1 column of energy storage containers 110 along the height direction Z can be m 51 times the sum of the sizes of the n5 standard containers along the height direction Z. That is, when n5 is 1, m 51 The sizes of the m5 columns of energy storage containers 110 along the height direction Z are the same, that is, the size of 1 column of energy storage containers 110 along the height direction Z can be m 51 times the sum of the sizes of the n5 standard containers along the height direction Z. That is, when n5 is 1, m 51 times the sum of the sizes of the n5 standard containers along the height direction Z. This can also facilitate transportation in the size of a standard container. When transportation is performed in the size of a standard container, the transportation cost can be greatly reduced.

[0321] Alternatively, m 51 The sizes of the m5 columns of energy storage containers 110 along the height direction Z are different, but at least m 51 The sizes of the m5 columns of energy storage containers 110 along the height direction Z are different, but at least m 51 The sizes of the m5 columns of energy storage containers 110 along the height direction Z are different, but at least m

[0322] In the embodiments of the present application, m 51 The sum of the sizes of the m5 columns of energy storage containers 110 along the height direction Z is equal to the sum of the sizes of the n5 standard containers along the height direction Z means that m 51 The sum of the sizes of the m5 columns of energy storage containers 110 along the height direction Z is equal to the sum of the sizes of the n5 standard containers along the height direction Z means that m 51 The sum of the sizes of the m5 columns of energy storage containers 110 along the height direction Z is equal to the sum of the sizes of the n5 standard containers along the height direction Z means that m

[0323] Alternatively, due to manufacturing errors, m 51 The sum of the sizes of the m5 columns of energy storage containers 110 along the height direction Z can have a difference of m51 a manufacturing error W1, W1≤5mm, i.e. m 51 The sum of the dimensions of the column of energy storage containers 110 along the height direction Z is equal to the sum of the dimensions of n5 standard containers along the height direction Z, or m 51 The sum of the dimensions of the column of energy storage containers 110 along the height direction Z plus m 51 W1 is equal to the sum of the dimensions of n5 standard containers along the height direction Z.

[0324] For example, m 51 =2, n5=1, the height h of the energy storage container 110 is 1293mm, the height H of the corresponding standard container is 2591mm, n5xH-m 51 xh=5mm, 5mm 51 xW1=10mm; therefore, m 51 The sum of the dimensions of the column of energy storage containers 110 along the height direction Z is equal to the sum of the dimensions of n5 standard containers along the height direction Z.

[0325] By adopting the above technical solution, m 41 The dimension of the energy storage container 110 along the width direction Y of the container body 111 is n4 times the dimension of a standard container along the width direction Y, m 51 The dimension of the energy storage container 110 along the height direction Z of the container body 111 is n5 times the dimension of a standard container along the height direction Z, which can make the space occupied by the plurality of energy storage containers 110 in stacking the same as the space occupied by at least one standard container, improve the utilization rate of the space where the energy storage containers 110 are placed, be conducive to fully utilizing the length space and height space in the transportation process, reduce the space waste of the energy storage containers 110 in the transportation process, and reduce the transportation cost of the energy storage containers 110, thereby further reducing the use cost of the energy storage device 100.

[0339] By adopting the technical scheme, when the plurality of energy storage containers 110 in the energy storage device 100 is transported, not only a certain number of energy storage containers 110 can be arranged and disposed along the width direction Y of the box body 111, but also a certain number of energy storage containers 110 can be stacked and disposed along the height direction Z of the box body 111, so that the certain number of energy storage containers 110 can just occupy the space required by at least one standard container, the space utilization rate of the energy storage containers 110 is improved, and the transportation cost of the energy storage containers 110 is reduced.

[0340] In some embodiments of the present application, m 41 = 3, n4 = 2, m 51 = 3, n5 = 1.

[0341] By adopting the above technical solutions, when transporting the plurality of energy storage containers 110 in the energy storage device 100, not only a certain number of energy storage containers 110 can be arranged along the width direction Y of the box body 111, but also a certain number of energy storage containers 110 can be stacked along the height direction Z of the box body 111, so that the certain number of energy storage containers 110 can just occupy the space required by at least one standard container, thereby improving the space utilization rate of the energy storage containers 110, and being conducive to reducing the transportation cost of the energy storage containers 110.

[0342] In some embodiments of the present application, m 41 = 3, n4= 2, m 51 = 3, n5= 2.

[0343] By adopting the above technical solutions, when transporting the plurality of energy storage containers 110 in the energy storage device 100, not only a certain number of energy storage containers 110 can be arranged along the width direction Y of the box body 111, but also a certain number of energy storage containers 110 can be stacked along the height direction Z of the box body 111, so that the certain number of energy storage containers 110 can just occupy the space required by at least one standard container, thereby improving the space utilization rate of the energy storage containers 110, and being conducive to reducing the transportation cost of the energy storage containers 110.

[0344] In some embodiments of the present application, referring to FIG. 6, the plurality of energy storage containers 110 include a fifth energy storage container and a sixth energy storage container arranged along the width direction Y of the box body 111, the box body 111 of the fifth energy storage container is provided with a fifth connecting portion 1117 facing one side of the sixth energy storage container, the box body 111 of the sixth energy storage container is provided with a sixth connecting portion 1118 facing one side of the fifth energy storage container, and the fifth connecting portion 1117 is connected with the sixth connecting portion 1118.

[0345] The fifth connecting portion 1117 and the sixth connecting portion 1118 cooperatively constitute at least part of a third connecting structure for connecting two energy storage containers 110 adjacent along the width direction Y, and the connection mode of the fifth connecting portion 1117 and the sixth connecting portion 1118 can be, but is not limited to, welding, clamping, threaded connection, etc.

[0346] The two energy storage containers 110 assembled and transported along the width direction Y are connected and fixed through the above third connecting structure, so that m 41 The energy storage containers 110 along the width direction Y form the size of n4 standard containers along the width direction Y, and further include the size of the third connecting structure along the width direction Y between each other. That is, when the third connecting structure is arranged, m 41The size of some of the energy storage containers 110 along the width direction Y can be the sum of the size of the energy storage container 110 itself and the size of the third connecting structure connected to the energy storage container 110 along the width direction Y. Because the third connecting structure connecting the energy storage containers 110 along the width direction Y also occupies the width size of the energy storage container 110 to some extent.

[0347] Exemplarily, when m 41 energy storage containers 110 are assembled and fixed for transportation through the third connecting structure, the sum of the size of m 41 energy storage containers 110 along the width direction Y and the sum of the size of m 41 -1 third connecting structures along the width direction Y is equal to the sum of the size of n4 standard containers along the width direction Y. Alternatively, the number of third connecting structures in m 41 energy storage containers 110 can be less than m 41 -1, and then these energy storage containers 110 are assembled into the size of the standard container, including the sum of the size of m 41 energy storage containers 110 along the width direction Y and the sum of the size of the actual third connecting structures along the width direction Y.

[0348] Exemplarily, the size of the third connecting structure along the width direction Y is W6, and W6≤30mm. As an example, m 41 =3, n4=2, the width k of the energy storage container 110 is 1605mm, and the width K of the corresponding standard container is 2438mm, n4×K-m 41 ×k=57mm, 57mm 41 ×W5+(m 41 -1)×W6=75mm; therefore, the sum of the size of m 41 energy storage containers 110 along the width direction Y is equal to the sum of the size of n4 standard containers along the width direction Y.

[0349] Therefore, when the energy storage device 100 uses the third connecting structure for transportation, and the energy storage containers 110 constituting the energy storage device 100 do not need the third connecting structure, the sum of the size of m 41 energy storage containers 110 along the width direction Y of the container 111 is equal to the sum of the size of n4 standard containers along the width direction Y should be understood as including the size of the third connecting structure used along the width direction Y. That is, the sum of the size of m 41 energy storage containers 110 along the width direction Y is equal to the sum of the size of n4 standard containers along the width direction Y minus the sum of the size of the third connecting structure used along the width direction Y. Such a case also belongs to the case of the embodiments of claims 15 to 17 of the present application.

[0350] As an example, the fifth connecting part 1117 can be a fifth locking hole, and the sixth connecting part 1118 can be a fifth locking piece, which is locked and connected in the fifth locking hole.

[0351] As an example, the fifth connecting part 1117 can be a sixth locking piece, and the sixth connecting part 1118 can be a sixth locking hole, which is locked and connected in the sixth locking hole.

[0352] As an example, the fifth connecting part 1117 can be a fifth locking hole, and the sixth connecting part 1118 can be a sixth locking hole, and the third connecting structure further includes a third connecting piece, which is connected to the fifth locking hole at one end along the width direction Y of the box body 111, and is connected to the sixth locking hole at the other end along the width direction Y of the box body 111.

[0353] By adopting the above technical solution, the energy storage container 110 will not exceed the size of the standard container along the length direction X and the width direction Y during transportation, which is more conducive to improving the convenience of the energy storage container 110 during transportation, further reducing the transportation cost of the energy storage container 110, and further reducing the use cost of the energy storage device 100.

[0354] In some embodiments of the present application, the second direction is the length direction of the box body 111, and the size of the box body 111 along the width direction is smaller than the size of the standard container along the width direction.

[0355] It should be noted that in actual application, the size of the box body 111 along the length direction X, the size of the box body 111 along the height direction Z and the size of the box body 111 along the width direction Y can correspond to the size of the standard container of the same standard size, or can correspond to the size of the standard container of different standard sizes.

[0357] As an example, the dimensions of the box 111 along the length direction X, the height direction Z, and the width direction Y are less than the dimensions of a 10-foot standard container along the length direction X, the height direction Z, and the width direction Y, respectively, i.e., the length of the box 111 is less than the length of a 10-foot standard container, the height of the box 111 is less than the height of a 10-foot standard container, and the width of the box 111 is less than the width of a 10-foot standard container.

[0359] As an example, the dimensions of the box 111 along the length direction X and the height direction Z are less than the dimensions of a 20-foot standard container along the length direction X and the height direction Z, respectively, i.e., the length of the box 111 is less than the length of a 20-foot standard container, the height of the box 111 is less than the height of a 20-foot standard container, and the dimension of the box 111 along the width direction Y is less than the dimension of a 30-foot standard container along the width direction Y, i.e., the width of the box 111 is less than the width of a 30-foot standard container.

[0360] In yet other embodiments, the dimensions of the box 111 along the length direction X and the height direction Z are less than the dimensions of a standard container of one standard size along the length direction X and the height direction Z, and the dimension of the box 111 along the width direction Y is less than the dimension of a standard container of the standard size along the width direction Y.

[0361] As an example, the dimensions of the box 111 along the length direction X and the height direction Z are less than the dimensions of a 20-foot standard container along the length direction X and the height direction Z, respectively, i.e., the length of the box 111 is less than the length of a 20-foot standard container, the height of the box 111 is less than the height of a 20-foot standard container, and the dimension of the box 111 along the width direction Y is less than the dimension of a 20-foot standard container along the width direction Y, i.e., the width of the box 111 is less than the width of a 20-foot standard container.

[0362] In still other embodiments, the dimension of the box 111 along the length direction X is less than the dimension of a standard container of one standard size along the length direction X, the dimension of the box 111 along the width direction Y is less than the dimension of a standard container of the standard size along the width direction Y, and the dimension of the box 111 along the height direction Z is less than the dimension of a standard container of another standard size along the height direction Z.

[0363] As an example, the size of the box 111 along the length direction X is less than the size of a 20-foot standard container along the length direction X, i.e., the length of the box 111 is less than the length of a 20-foot standard container, the size of the box 111 along the width direction Y is less than the size of a 20-foot standard container along the width direction Y, i.e., the width of the box 111 is less than the width of a 20-foot standard container, and the size of the box 111 along the height direction Z is less than the size of a 30-foot standard container along the height direction Z, i.e., the height of the box 111 is less than the height of a 30-foot standard container.

[0364] In some embodiments, the size of the box 111 along the length direction X is less than the size of a 20-foot standard container along the length direction X, i.e., the length of the box 111 is less than the length of a 20-foot standard container, the size of the box 111 along the width direction Y is less than the size of a 20-foot standard container along the width direction Y, i.e., the width of the box 111 is less than the width of a 20-foot standard container, and the size of the box 111 along the height direction Z is less than the size of a 30-foot standard container along the height direction Z, i.e., the height of the box 111 is less than the height of a 30-foot standard container.

[0365] As an example, the size of the box 111 along the length direction X is less than the size of a 20-foot standard container along the length direction X, i.e., the length of the box 111 is less than the length of a 20-foot standard container, the size of the box 111 along the width direction Y is less than the size of a 20-foot standard container along the width direction Y, i.e., the width of the box 111 is less than the width of a 20-foot standard container, and the size of the box 111 along the height direction Z is less than the size of a 30-foot standard container along the height direction Z, i.e., the height of the box 111 is less than the height of a 30-foot standard container.

[0366] By adopting the above technical solutions, the energy storage container 110 will not exceed the size of a standard container along the length direction or the size of a standard container along the width direction in the process of transportation, which is more conducive to improving the convenience of the energy storage container 110 in the process of transportation, further reducing the transportation cost of the energy storage container 110, and further reducing the use cost of the energy storage device 100.

[0367] In some embodiments of the present application, the energy storage device 100 includes a plurality of energy storage containers 110, m6 energy storage containers 110 in the plurality of energy storage containers 110 are arranged along the length direction of the box 111, m7 rows of energy storage containers 110 are arranged into an array structure along the width direction of the box 111, and m8 array structures are stacked along the height direction of the box 111, wherein m6, m7 and m8 are positive integers greater than or equal to 2.

[0368] In some embodiments, the energy storage device 100 includes at least 8 energy storage containers 110, and the number of energy storage containers 110 in the energy storage device 100 is an integer multiple of 4.

[0369] As an example, the energy storage device 100 includes eight energy storage containers 110. During assembly of the energy storage device 100, two energy storage containers 110 may be arranged in a row along the length direction X of the container body 111. The two rows of energy storage containers 110 may then be arranged in an array structure along the width direction Y of the container body 111. Finally, the two array-structured energy storage containers 110 may be stacked along the height direction Z of the container body 111.

[0370] As an example, the energy storage device 100 includes 12 energy storage containers 110. During assembly of the energy storage device 100, three energy storage containers 110 can be arranged into a row along the length direction X of the box body 111, two rows of energy storage containers 110 can be arranged into an array structure along the width direction Y of the box body 111, and two array-structured energy storage containers 110 can be stacked along the height direction Z of the box body 111.

[0371] By adopting the above technical solution, more energy storage containers 110 can be configured when the footprint of the energy storage device 100 remains the same, thereby further improving the area energy density of the energy storage system 1000 and thus further enhancing the performance of the energy storage system 1000.

[0372] In some embodiments of the present application, m of the m6 energy storage containers 110 61 The sum of the dimensions of the energy storage containers 110 along the length direction X of the box body 111 is equal to the sum of the dimensions of n6 standard containers along the length direction X, and n6 is less than m 61 A positive integer, m7 rows of energy storage containers 110 71 The sum of the dimensions of the energy storage containers 110 along the width direction Y of the box body 111 is equal to the sum of the dimensions of n7 standard containers along the width direction Y, where n7 is less than m 71 A positive integer, m in the m8 array structure 81 The sum of the dimensions of the array structures along the height direction Z of the box body 111 is equal to the sum of the dimensions of n8 standard containers along the height direction Z, and n8 is less than m 81 A positive integer.

[0373] m6 energy storage containers m out of 110 61 The energy storage containers 110 refer to any m6 energy storage containers 110. 61 Energy storage containers 110. For example, the energy storage device 100 has eight energy storage containers 110, namely the first energy storage container, the second energy storage container, the third energy storage container, the fourth energy storage container, the fifth energy storage container, the sixth energy storage container, the seventh energy storage container and the eighth energy storage container. 61= 2, the two energy storage containers 110 can be the first and third energy storage containers, the second and fourth energy storage containers, or the fifth and eighth energy storage containers.

[0374] may be m 61 less than m6, the sum of the lengths of the m6 energy storage containers 110 is equal to the sum of the lengths of the n6 standard containers. 61 = 5, n6 = 3; wherein the five energy storage containers 110 can be any five of the eight energy storage containers 110, and the sum of the lengths of the five energy storage containers 110 is equal to the length of one standard container.

[0375] may also be m 61 = m6, the sum of the lengths of the m6 energy storage containers 110 is equal to the sum of the lengths of the n6 standard containers. 61 = m6, n6 = 1, the sum of the lengths of the two energy storage containers 110 is equal to the length of one standard container.

[0376] may be that the lengths of the energy storage containers 110 are the same, i.e., the lengths of the energy storage containers 110 can be m 61 times the sum of the lengths of the n6 standard containers along the length direction X, i.e., the sum of the lengths of the m 61 energy storage containers 110 along the length direction X is equal to the sum of the lengths of the n6 standard containers along the length direction X. In this way, when n6 is 1, the m 61 energy storage containers 110 can form the length of one standard container along the length direction X, facilitating land and sea transportation in the size of one standard container; when n6 is an integer greater than 1, the m 61 energy storage containers 110 can form the length of n6 standard containers along the length direction X, which can also facilitate transportation in the size of a standard container. When transportation is performed in the size of a standard container, transportation costs can be greatly reduced.

[0377] Optionally, the lengths of the m 61 energy storage containers 110 along the length direction X can also be different, but at least the sum of the lengths of the m 61 energy storage containers 110 along the length direction X is equal to the length of n6 standard containers along the length direction X. In this way, the m 61 energy storage containers 110 with different lengths along the length direction X can be assembled into the length of one or more standard containers along the length direction X, greatly facilitating transportation and reducing transportation costs.

[0378] In the embodiments of the present application, the sum of the sizes of the m energy storage containers 110 along the length direction X is approximately equal to the sum of the sizes of the n6 standard containers along the length direction X. 61 The sum of the sizes of the m energy storage containers 110 along the length direction X is approximately equal to the sum of the sizes of the n6 standard containers along the length direction X. When the size difference between the sum of the sizes of the m energy storage containers 110 along the length direction X and the sum of the sizes of the n6 standard containers along the length direction X is within the above tolerance range, it can be considered that the sizes are approximately equal. 61 The sum of the sizes of the m energy storage containers 110 along the length direction X is approximately equal to the sum of the sizes of the n6 standard containers along the length direction X. When the size difference between the sum of the sizes of the m energy storage containers 110 along the length direction X and the sum of the sizes of the n6 standard containers along the length direction X is within the above tolerance range, it can be considered that the sizes are approximately equal. 61 The sum of the sizes of the m energy storage containers 110 along the length direction X is approximately equal to the sum of the sizes of the n6 standard containers along the length direction X. When the size difference between the sum of the sizes of the m energy storage containers 110 along the length direction X and the sum of the sizes of the n6 standard containers along the length direction X is within the above tolerance range, it can be considered that the sizes are approximately equal.

[0379] Alternatively, due to manufacturing errors, the sum of the sizes of the m energy storage containers 110 along the length direction X can have a manufacturing error W3, W3≤5mm, that is, the sum of the sizes of the m energy storage containers 110 along the length direction X is equal to the sum of the sizes of the n6 standard containers along the length direction X plus m 61 The sum of the sizes of the m energy storage containers 110 along the length direction X is approximately equal to the sum of the sizes of the n6 standard containers along the length direction X. When the size difference between the sum of the sizes of the m energy storage containers 110 along the length direction X and the sum of the sizes of the n6 standard containers along the length direction X is within the above tolerance range, it can be considered that the sizes are approximately equal. 61 The sum of the sizes of the m energy storage containers 110 along the length direction X is approximately equal to the sum of the sizes of the n6 standard containers along the length direction X.

When the size difference between the sum of the sizes of the m energy storage containers 110 along the length direction X and the sum of the sizes of the n6 standard containers along the length direction X is within the above tolerance range, it can be considered that the sizes are approximately equal.

[0380] For example, m 61 =2, n6=1, the length l of the energy storage container 110 is 3027mm, and the length L of the corresponding standard container is 6058mm, n6xL-m 61 x l=4mm, 4mm 61 x W3=10mm; therefore, the sum of the sizes of the m energy storage containers 110 along the length direction X is equal to the sum of the sizes of the n6 standard containers along the length direction X. 61 The sum of the sizes of the m energy storage containers 110 along the length direction X is approximately equal to the sum of the sizes of the n6 standard containers along the length direction X. When the size difference between the sum of the sizes of the m energy storage containers 110 along the length direction X and the sum of the sizes of the n6 standard containers along the length direction X is within the above tolerance range, it can be considered that the sizes are approximately equal.

[0381] The m 71 energy storage containers 110 in the m7 rows of energy storage containers 110 refer to any m 71 energy storage containers 110 in the m7 rows of energy storage containers 110. For example, the energy storage device 100 has 4 rows of energy storage containers 110, and m 71 =2, the 2 rows of energy storage containers 110 can be the first and third rows, or the first and second rows, or the second and fourth rows.

[0382] The m 71 energy storage containers 110 in the m7 rows of energy storage containers 110 refer to any m 71= 5, n7= 3; wherein, the 5 rows of energy storage containers 110 can be any 5 rows of energy storage containers 110 in the 8 rows of energy storage containers 110, and the sum of the widths of the 5 rows of energy storage containers 110 is equal to the width of 1 standard container.

[0383] Also, m 71 = m7, and the sum of the widths of the m7 rows of energy storage containers 110 along the width direction Y is equal to the sum of the widths of the n7 standard containers along the width direction Y. For example, m7= 2, and the sum of the widths of the 2 rows of energy storage containers 110 is equal to the width of 1 standard container. 71 = m7, n7= 1, and the sum of the widths of the 2 rows of energy storage containers 110 is equal to the width of 1 standard container.

[0384] The energy storage containers 110 along the width direction Y can have the same size, i.e., the size of the energy storage containers 110 along the width direction Y can be m 71 times the sum of the widths of the n7 standard containers along the width direction Y. That is, m 71 = n7, and the sum of the widths of the n7 rows of energy storage containers 110 along the width direction Y is equal to the sum of the widths of the n7 standard containers along the width direction Y. In this way, when n7 is 1, m 71 = 1, and the n7 rows of energy storage containers 110 can form the size of 1 standard container along the width direction Y, which is convenient for land transportation and sea transportation in the size of 1 standard container; when n7 is an integer greater than 1, m 71 = n7, and the n7 rows of energy storage containers 110 can form the size of n7 standard containers along the width direction Y, which is also convenient for transportation in the size of a standard container. When the energy storage containers 110 are transported in the size of a standard container, the transportation cost can be greatly reduced.

[0385] Optionally, m 71 = n7, and the sum of the widths of the n7 rows of energy storage containers 110 along the width direction Y is equal to the sum of the widths of the n7 standard containers along the width direction Y. In this way, the m 71 = n7, and the sum of the widths of the n7 rows of energy storage containers 110 along the width direction Y is equal to the sum of the widths of the n7 standard containers along the width direction Y. In this way, the m 71 = n7, and the sum of the widths of the n7 rows of energy storage containers 110 along the width direction Y is equal to the sum of the widths of the n7 standard containers along the width direction Y. In this way, the m

[0386] In the embodiments of the present application, m 71 = n7, and the sum of the widths of the n7 rows of energy storage containers 110 along the width direction Y is equal to the sum of the widths of the n7 standard containers along the width direction Y. In this way, the m 71 = n7, and the sum of the widths of the n7 rows of energy storage containers 110 along the width direction Y is equal to the sum of the widths of the n7 standard containers along the width direction Y. In this way, the m 71The dimension difference between the sum of the dimensions of the energy storage container 110 along the width direction Y and the sum of the dimensions of the n7 standard containers along the width direction Y is within the tolerance range, and the dimensions are considered approximately equal.

[0387] Optionally, due to manufacturing errors, m 71 The sum of the dimensions of the energy storage container 110 along the width direction Y can have m 71 manufacturing errors W5, W5≤5mm, i.e., m 71 The sum of the dimensions of the energy storage container 110 along the width direction Y is equal to the sum of the dimensions of the n7 standard containers along the width direction Y, and m 71 The sum of the dimensions of the energy storage container 110 along the width direction Y plus m 71 W5 is equal to the sum of the dimensions of the n7 standard containers along the width direction Y.

[0388] For example, m 71 =2, n7=1, the width k of the energy storage container 110 is 1215mm, and the width K of the corresponding standard container is 2438mm, n7×K-m 71 ×k=8mm, 8mm 71 ×W5=10mm; therefore, m 71 The sum of the dimensions of the energy storage container 110 along the width direction Y is equal to the sum of the dimensions of the n7 standard containers along the width direction Y.

[0389] The m 81 array structures in the m8 array structures refer to any m 81 array structures in the m8 array structures. For example, the energy storage device 100 includes 8 array structures, and the 8 array structures are stacked along the height direction Z. If m 81 =2, the two array structures can be the first array structure and the second array structure, or the first array structure and the third array structure, or the second array structure and the fourth array structure.

[0390] The m 81 array structures in the m8 array structures can be less than m8, and the sum of the dimensions of the array structures along the height direction Z is equal to the sum of the dimensions of the n8 standard containers along the height direction Z. For example, m8=8, m 81 =5, and n8=3. The 5 array structures can be any 5 array structures in the 8 array structures, and the sum of the heights of the 5 array structures is equal to the height of one standard container.

[0391] The m 81 array structures in the m8 array structures can be equal to m8, and the sum of the dimensions of the m8 array structures along the height direction Z is equal to the sum of the dimensions of the n8 standard containers along the height direction Z. For example, m8=2, and m81 m8n8=1, the sum of the heights of the 1 array structure is equal to the height of 1 standard container.

[0392] m 81 The size of the 1 array structure along the height direction Z is the same as the size of the n8 standard containers along the height direction Z, that is, the size of the 1 array structure along the height direction Z is m 81 times the size of the sum of the sizes of the n8 standard containers along the height direction Z, and the size of the sum of the sizes of the m 81 array structures along the height direction Z is equal to the size of the sum of the sizes of the n8 standard containers along the height direction Z. In this way, when n8 is 1, the m 81 array structures can form the size of 1 standard container along the height direction Z, facilitating the assembly of the size of 1 standard container for land transportation and sea transportation; when n8 is an integer greater than 1, the m 81 array structures can form the size of n8 standard containers along the height direction Z, which can also facilitate transportation in the size of a standard container. When the size of the standard container is transported, the transportation cost can be greatly reduced.

[0393] Alternatively, the size of the m 81 array structures along the height direction Z can be different, but at least the size of the sum of the sizes of the m 81 array structures along the height direction Z is equal to the size of the n8 standard containers along the height direction Z. In this way, the m 81 array structures with different sizes along the height direction Z can be assembled into the size of 1 or more standard containers along the height direction Z, to greatly facilitate transportation and reduce transportation costs.

[0394] In the embodiments of the present application, the sum of the sizes of the m 81 array structures along the height direction Z is equal to the sum of the sizes of the n8 standard containers along the height direction Z, which means that the sum of the sizes of the m 81 array structures along the height direction Z is approximately equal to the sum of the sizes of the n8 standard containers along the height direction Z. When the size difference between the sum of the sizes of the m 81 array structures along the height direction Z and the sum of the sizes of the n8 standard containers along the height direction Z is within the above tolerance range, it can be considered that the sizes are approximately equal.

[0395] Alternatively, due to manufacturing errors, the sum of the sizes of the m 81 array structures along the height direction Z can have a manufacturing error W1, W1≤5mm, that is, the sum of the sizes of the m 81 array structures along the height direction Z is equal to the sum of the sizes of the n8 standard containers along the height direction Z, and the sum of the sizes of the m 81 array structures along the height direction Z is equal to the sum of the sizes of the n8 standard containers along the height direction Z, and the sum of the sizes of the m 81The sum of the sizes of the array structures along the height direction Z plus m 81 W1 is equal to the sum of the sizes of n8 standard containers along the height direction Z.

[0396] For example, m 81 = 2, n8 = 1, the height h of the energy storage container 110 is 1293 mm, the height H of the corresponding standard container is 2591 mm, n3 x H - m 31 x h = 5 mm, 5 mm < m 31 x W1 = 10 mm; therefore, m 81 The sum of the sizes of the array structures along the height direction Z is equal to the sum of the sizes of n8 standard containers along the height direction Z.

[0397] By adopting the technical scheme, m 61 The size of the energy storage container 110 along the length direction X of the container body 111 is the size of n6 standard containers along the length direction X, m 71 The size of the energy storage container 110 along the width direction Y of the container body 111 is the size of n7 standard containers along the width direction Y, m 81 The size of the array structure along the height direction Z of the container body 111 is the size of n8 standard containers along the height direction Z, which can make the space occupied by the plurality of energy storage containers 110 in stacking the same as the space occupied by at least one standard container, improve the utilization rate of the space for placing the energy storage container 110, be conducive to fully utilizing the length space, width space and height space in the transportation process, reduce the space waste in the transportation process of the energy storage container 110, and reduce the transportation cost of the energy storage container 110, thereby further reducing the use cost of the energy storage device 100.

[0425] By adopting the above technical solutions, when transporting the plurality of energy storage containers 110 in the energy storage equipment 100, not only a certain number of energy storage containers 110 can be arranged and disposed along the length direction X and the width direction Y of the box body 111, but also a certain number of energy storage containers 110 can be stacked along the height direction Z of the box body 111, so that the certain number of energy storage containers 110 can just occupy the space required by at least one standard container, thereby improving the space utilization rate of the energy storage containers 110, and being conducive to reducing the transportation cost of the energy storage containers 110.

[0426] In some embodiments of the present application, the second direction is the width direction Y of the box body 111, and the size of the box body 111 along the length direction X is greater than the size of the standard container along the length direction X.

[0427] It should be noted that, in actual application, the size of the box body 111 along the length direction X, the size of the box body 111 along the height direction Z, and the size of the box body 111 along the width direction Y can correspond to the size of a standard container of the same standard size, or can correspond to the size of a standard container of different standard sizes.

[0434] In some embodiments, the size of the box 111 along the width direction Y is smaller than the size of a standard container of a standard size along the width direction Y, the size of the box 111 along the length direction X is larger than the size of the standard container of the standard size along the length direction X, and the size of the box 111 along the height direction Z is smaller than the size of a standard container of another standard size along the height direction Z.

[0435] For example, the size of the box 111 along the width direction Y is smaller than the size of a 20-foot standard container along the width direction Y, i.e., the width of the box 111 is smaller than the width of the 20-foot standard container, the size of the box 111 along the length direction X is larger than the size of the 20-foot standard container along the length direction X, i.e., the length of the box 111 is larger than the length of the 20-foot standard container, and the size of the box 111 along the height direction Z is smaller than the size of a 30-foot standard container along the height direction Z, i.e., the height of the box 111 is smaller than the height of the 30-foot standard container.

[0437] For example, the size of the box 111 along the height direction Z is smaller than the size of a 20-foot standard container along the height direction Z, i.e., the height of the box 111 is smaller than the height of the 20-foot standard container, the size of the box 111 along the length direction X is larger than the size of the 20-foot standard container along the length direction X, i.e., the length of the box 111 is larger than the length of the 20-foot standard container, and the size of the box 111 along the width direction Y is smaller than the size of a 30-foot standard container along the width direction Y, i.e., the width of the box 111 is smaller than the width of the 30-foot standard container.

[0438] By employing the above technical solutions, the capacity of the box 111 can be increased, so that the box 111 can accommodate more battery modules 112, thereby effectively improving the electric capacity of the energy storage device 100 and effectively improving the performance of the energy storage device 100.
