In order to improve the smoothness of electric energy supply and realize the normal operation of production and life, an energy storage system needs to be used. The energy storage system includes an energy storage device. The energy storage device is a device for cyclically storing and releasing electric energy. Through charging or discharging of the energy storage device, electric energy can be stored in the energy storage device, or the electric energy stored in the energy storage device can be supplied to an electric device.

DETAILED DESCRIPTION

[0113] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and not to limit the present application.

[0114] 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.

[0115] It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0116] In addition, the terms "first", "second", "third", "fourth", "fifth", "sixth", "seventh", "eighth", "ninth", "tenth" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second", "third", "fourth", "fifth", "sixth", "seventh", "eighth", "ninth", "tenth" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0117] In the present application, the battery cell can include a lithium ion secondary battery cell, a lithium ion primary battery cell, a lithium-sulfur battery cell, a sodium lithium ion battery cell, a sodium ion battery cell, or a magnesium ion battery cell, etc., and the embodiments of the present application are not limited thereto. The battery cell can be in the shape of a cylinder, a flat body, a cuboid, or other shapes, etc., and the embodiments of the present application are not limited thereto.

[0118] The battery mentioned in the embodiments of the present application can 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 a mixed connection through a busbar component.

[0119] In some embodiments, the battery can be a battery module. When there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module.

[0120] In some embodiments, the battery can be a battery pack, which includes a housing box and battery cells, and the battery cells or battery modules are accommodated in the housing box.

[0121] The battery cell generally includes an electrode assembly. The electrode assembly includes a positive electrode, a negative electrode, and a separator. During the charging and discharging process of the battery cell, active ions (such as lithium ions) are embedded and extracted between the positive electrode and the negative electrode. The separator is arranged between the positive electrode and the negative electrode, which can prevent the positive and negative electrodes from short-circuiting, and at the same time, the active ions can pass through.

[0122] Optionally, the electrode assembly is in a jelly-roll structure. The positive electrode sheet and the negative electrode sheet are wound into a jelly-roll structure.

[0123] Optionally, the electrode assembly is in a stacked structure.

[0124] Optionally, the shape of the electrode assembly can be cylindrical, flat, or polygonal, etc.

[0125] The area energy density requirement of the energy storage equipment 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 transportation, and there is a transportation weight limit for land and sea transportation in general, so there is a contradiction between the improvement of the energy density and the weight of the energy storage container. In addition, when assembling the energy storage system, the energy storage container usually needs to be arranged separately from the electrical components such as transformers and power conversion devices. Since the spacing space between the power conversion device and the energy storage container and the spacing space between the power conversion device and the transformer cannot be utilized, space is wasted, which is not conducive to improving the area energy density of the energy storage system, thereby causing the performance of the energy storage system to decrease.

[0126] Therefore, 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 an energy storage device and an energy storage system including the energy storage device.

[0127] The energy storage system can be used in an energy storage power station, a wind power generation system, a solar power generation system, a mobile power system, or a temporary power supply system, etc. The energy storage power station can store electric energy during a low electricity consumption period, and provide electric energy for related users or electric equipment during a high electricity consumption period. The wind power generation system can store electric energy collected by a wind turbine generator after the electric energy is converted from wind energy, and supply the electric energy to users in time. The solar power generation system can store electric energy converted from solar energy, and supply the electric energy to users in time. The mobile power system can supply electric energy for related electric equipment in places where a power grid supply system cannot reach, such as remote mountainous areas, remote wild areas, etc. The temporary power supply system can supply electric energy for users in a situation of insufficient power supply. The energy storage system provided in the embodiments of the present application can be any power system requiring the use of an energy storage device.

The charging pile 300 has a connector, which can be connected to electric equipment, so as to supply electric energy to the electric equipment. The charging network 2000 applies the energy storage device 100, which can effectively improve the performance of the charging network 2000, and also effectively reduce the use cost of the charging network 2000.

[0139] Optionally, for various sizes of standard containers, the dimensions within a range of ±5% of the size can be considered as dimensions within a tolerance range.

[0140] In some embodiments, the first direction can be one of a height direction Z, a length direction X and a width direction Y of the box 111.

[0141] As an example, the size of the box 111 along the first direction is less than the size of a 10-foot standard container along the first direction.

[0142] As an example, the size of the box 111 along the first direction is less than the size of a 20-foot standard container along the first direction.

[0143] As an example, the size of the box 111 along the first direction is less than the size of a 30-foot standard container along the first direction.

[0144] As an example, the size of the box 111 along the first direction is less than the size of a 40-foot standard container along the first direction.

[0145] As an example, the size of the box 111 along the first direction is less than the size of a 45-foot standard container along the first direction.

[0146] The box 111 is generally a cuboid structure, the length direction X and the width direction Y of the box 111 are parallel to a horizontal plane, the length direction X of the box 111 is parallel to the longest side of the cuboid structure of the box 111, the height direction Z of the box 111 is perpendicular to the ground, and the width direction Y of the box 111 is perpendicular to the length direction X and the height direction Z of the box 111.

[0147] The size a of the box 111 along the length direction X is the distance between the two ends of the box 111 along the length direction X, the size b of the box 111 along the width direction Y is the distance between the two ends of the box 111 along the width direction Y, and the size h of the box 111 along the height direction Z is the distance between the two ends of the box 111 along the height direction Z. The above-mentioned size a, size b and size h are the maximum dimensions of the outer contour of the box 111 in the corresponding direction.

[0148] In some embodiments, the box 111 can include eight corner pieces and six box walls, the eight corner pieces are located at the eight corners of the cuboid structure of the box 111, the eight corner pieces respectively protrude from the box walls of the box 111, the total span of the two corner pieces arranged along the height direction Z is the height of the box 111, the total span of the two corner pieces arranged along the length direction X is the length of the box 111, and the total span of the two corner pieces arranged along the width direction Y is the width of the box 111. When calculating the size of the box 111, the pipelines and cables connected to the box 111 and located outside the box 111 are not included in the size of the box 111.

[0149] The battery module 112 is placed in the box 111, and the battery module 112 includes a plurality of battery cells 1121 which can be connected in series, in parallel, or in a mixed connection.

[0150] Referring to FIG. 8, the battery cell 1121 in the embodiment of the present application includes an electrode assembly 11212 and a case 11210 having a receiving cavity 11214 in which the electrode assembly 11212 is received.

[0151] The case 11210 includes a case body 11211 and an end cover 11213. In assembling the battery cell 1121, the electrode assembly 11212 is first placed in the receiving cavity 11214, and then the end cover 11213 is coupled to the case body 11211, and electrolyte is injected into the receiving cavity 11214 through an electrolyte injection port in the end cover 11213.

[0152] Optionally, the case 11210 can also be used to contain electrolyte, such as the electrolyte.

[0153] The case 11210 can have various shapes, such as a cylindrical shape, a cuboid shape, etc. The shape of the case 11210 can be determined according to the specific shape of the electrode assembly 11212. For example, if the electrode assembly 11212 has a cylindrical structure, the case 11210 can also have a cylindrical structure. If the electrode assembly 11212 has a cuboid structure, the case 11210 can also have a cuboid structure.

[0154] The case 11210 can be made of various materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, etc., and the embodiment of the present application does not make special limitations on this.

[0155] The electrode assembly 11212 contained in the case 11210 can be one or more. As an example, as shown in FIG. 8, the electrode assembly 11212 contained in the case 11210 is two.

[0156] The power conversion device 120 can be electrically connected to the power grid to convert the power provided by the power grid. The energy storage container 110 is electrically connected to the power conversion device 120, and the power conversion device 120 guides the power provided by the power grid into the energy storage container 110 after power conversion.

[0157] The size of the box 111 of the energy storage device 100 in the first direction is smaller than the size of a standard container in the first direction, so that the energy storage container 110 does not exceed the size of the standard container in the first direction during transportation, which facilitates the transportation of the energy storage container 110 and reduces the transportation cost of the energy storage container 110, thereby effectively reducing the use cost of the energy storage system 1000 using the energy storage device 100. At the same time, by accommodating the power conversion device 120 in the box 111, the power conversion device 120 is integrated with the energy storage container 110 as a whole, which effectively saves the spacing space of the power conversion device 120 and the energy storage container 110 or other electrical equipment in the energy storage device, compared with the conventional separate arrangement of the power conversion device 120 and the energy storage container 110. Thus, under the same land area of the energy storage system 1000, more energy storage containers 110 can be configured, which effectively improves the area energy density of the energy storage system 1000, thereby effectively improving the performance of the energy storage system 1000.

[0158] In some embodiments of the present application, the first direction is the height direction Z of the box 111.

[0159] For example, the size of the box 111 in the height direction Z is smaller than the size of a 10-foot standard container in the height direction Z, that is, the height of the box 111 is smaller than the height of the 10-foot standard container.

[0160] For example, the size of the box 111 in the height direction Z is smaller than the size of a 20-foot standard container in the height direction Z, that is, the height of the box 111 is smaller than the height of the 20-foot standard container.

[0161] For example, the size of the box 111 in the height direction Z is smaller than the size of a 30-foot standard container in the height direction Z, that is, the height of the box 111 is smaller than the height of the 30-foot standard container.

[0162] For example, the size of the box 111 in the height direction Z is smaller than the size of a 40-foot standard container in the height direction Z, that is, the height of the box 111 is smaller than the height of the 40-foot standard container.

[0163] For example, the size of the box 111 in the height direction Z is smaller than the size of a 45-foot standard container in the height direction Z, that is, the height of the box 111 is smaller than the height of the 45-foot standard container.

[0164] By adopting the technical scheme, the size of the box body 111 along the height direction Z is smaller than the size of the standard container along the height direction Z, so that the energy storage container 110 does not exceed the size of the standard container along the height direction Z in the process of transportation, which is beneficial to improve the convenience of the energy storage container 110 in the process of transportation, reduce the transportation cost of the energy storage container 110, and effectively reduce the use cost of the energy storage system 1000 adopting the energy storage device 100.

[0165] In some embodiments of the present application, the energy storage device 100 includes m1 energy storage containers 110, the sum of the sizes of m 11 energy storage containers 110 along the height direction Z of the box body 111 is equal to the sum of the sizes of n1 standard containers along the height direction Z, where m1 is a positive integer greater than or equal to 2, and n1 is a positive integer less than m 11 .

[0166] The m 11 energy storage containers 110 in the m1 energy storage containers 110 refer to any m 11 energy storage containers 110 in the m1 energy storage containers 110. For example, the energy storage device 100 has three energy storage containers 110, which are the first energy storage container, the second energy storage container, and the third energy storage container. If m 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.

[0167] m 11 may be less than m1, and the sum of the sizes of part of the m1 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. For example, m1 = 8, m 11 = 5, and n1 = 3; the five energy storage containers 110 can be any five energy storage containers 110 in 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.

[0168] m 11 may be equal to m1, and the sum of the sizes of the m1 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. For example, m1 = 2, m 11 = m1, and n1 = 1, and the sum of the heights of the two energy storage containers 110 is equal to the height of one standard container.

[0169] 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.

[0170] 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.

[0171] 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: 11 The sum of the dimensions of the energy storage containers 110 along the height direction Z is approximately equal to the sum of the dimensions of n1 standard containers along the height direction Z. 11 When the difference between the sum of the dimensions of the energy storage containers 110 along the height direction Z and the sum of the dimensions of n1 standard containers along the height direction Z is within the above tolerance range, they can be considered to be approximately equal in size.

[0172] Optionally, the approximately equal difference is W, W≤m 11 ×35mm-30mm. For example, m 11 =2, the approximately equal difference W can be up to 40mm. When the difference between the sum of the dimensions of the two energy storage containers 110 along the height direction Z and the dimension of a standard container along the height direction Z is within 40mm, the sum of the dimensions of the two energy storage containers 110 along the height direction Z is equal to the dimension of a standard container along the height direction Z. For another example, m 11Wmax can be 75mm, when the sum of the sizes of the 3 energy storage containers 110 along the height direction Z and the size of 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 1 standard container along the height direction Z; or when the sum of the sizes of the 3 energy storage containers 110 along the height direction Z and the sum of the sizes of 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 2 standard containers along the height direction Z.

[0173] Optionally, due to manufacturing errors, m 11 The sum of the sizes of the m 11 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 11 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, or the sum of the sizes of the m 11 energy storage containers 110 along the height direction Z plus m 11 W1 is equal to the sum of the sizes of n1 standard containers along the height direction Z.

[0174] For example, m 11 =2, n1=1, the height h of the energy storage container 110 is 1293mm, and the height H of the corresponding standard container is 2591mm, n1xH-m 11 xh=5mm, 5mm 11 xW1=10mm; therefore, the sum of the sizes of the m 11 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.

[0175] By adopting the above technical solution, the size of the m 11 energy storage containers 110 along the height direction Z of the container body 111 is equal to the size of n1 standard containers along the height direction Z, so that the space occupied by the m 11 energy storage containers 110 when stacked is the same as the space occupied by n1 standard containers, which improves the utilization rate of the space for placing the energy storage containers 110, is conducive to fully utilizing the height space during transportation, reduces the space waste of the energy storage containers 110 during transportation, and reduces the transportation cost of the energy storage containers 110, thereby further reducing the use cost of the energy storage system 1000 adopting the above energy storage device 100.

[0176] In some embodiments of the present application, m 11 =2, n1=1.

[0177] The number of energy storage containers 110 in the energy storage device 100 can be more than 2, for example, the number of energy storage containers 110 in the energy storage device 100 is 3, 5, or 8. The number of energy storage containers 110 in the energy storage device 100 can also be 2.

[0178] By setting the height of the two energy storage containers 110 as the height of a standard container, when transporting the plurality of energy storage containers 110 in the energy storage device 100, the two adjacent 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 a standard container, improving the space utilization of the energy storage containers 110, and facilitating the reduction of the transportation cost of the energy storage containers 110.

[0179] In some embodiments of the present application, m 11 = 3, n1= 1.

[0180] By setting the height of the three energy storage containers 110 as the height of a standard container, when transporting the plurality of energy storage containers 110 in the energy storage device 100, the three adjacent 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 a standard container, improving the space utilization of the energy storage containers 110, and facilitating the reduction of the transportation cost of the energy storage containers 110.

[0181] In some embodiments of the present application, m 11 = 3, n1= 2.

[0182] 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 three adjacent 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, improving the space utilization of the energy storage containers 110, and facilitating the reduction of the transportation cost of the energy storage containers 110.

[0183] In some embodiments of the present application, please refer to FIG. 3 and FIG. 4 together, 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.

[0184] The number of the energy storage containers 110 in the energy storage device 100 can be any number greater than or equal to 2. For example, the energy storage device 100 includes two energy storage containers 110, which are stacked along the height direction Z during assembly of the energy storage device 100. For another example, the energy storage device 100 includes three energy storage containers 110, which are stacked along the height direction Z during assembly of the energy storage device 100.

[0185] In some embodiments, when the number of the energy storage containers 110 in the energy storage device 100 is too large, the bottommost energy storage container 110 is prone to damage. Therefore, 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 along the height direction Z.

[0186] By using the above technical solutions, more energy storage containers 110 can be configured in the energy storage device 100 with the same floor area, which further improves the area energy density of the energy storage system 1000, thereby further improving the performance of the energy storage system 1000.

[0187] 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 container body 111 of the first energy storage container is provided with a first connecting portion 1113. The top of the container body 111 of the second energy storage container is provided with a second connecting portion 1114. The first connecting portion 1113 is connected to the second connecting portion 1114.

[0188] The first connecting portion 1113 and the second connecting portion 1114 cooperate to form at least part of a connecting structure for connecting two adjacent energy storage containers 110 along the height direction Z. 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.

[0189] The two energy storage containers 110 transported and assembled along the height direction Z are connected and fixed by the above connecting structure. Therefore, the height of the m 11 energy storage containers 110 is the sum of the height of the n1 standard containers and the height of the connecting structure therebetween. That is, when the connecting structure is provided, the height of some of the m 11 energy storage containers 110 along the height direction Z can be the sum of the height of the energy storage container itself and the height of the connecting structure connected thereto. Because the connecting structure for connecting the energy storage containers 110 along the height direction Z also occupies the height dimension of the energy storage container 110 to some extent.

[0190] For example, when the m 11The sum of the sizes of the m 11 energy storage containers 110 along the height direction Z and the sum of the sizes of the m 11 -1 connection structures along the height direction Z is equal to the sum of the sizes of the n1 standard containers along the height direction Z. Alternatively, the number of connection structures in the m 11 energy storage containers 110 is less than m 11 -1, then when the m 11 energy storage containers 110 are assembled into the size of the standard container, the sum of the sizes of the m 11 energy storage containers 110 along the height direction Z and the sum of the sizes of the actual connection structures.

[0191] Exemplarily, the size of the connection structure along the height direction Z is W2, and W2≤30mm. As an example, m 11 =3, n1=2, the height h of the energy storage container 110 is 845mm, the height H of the corresponding standard container is 2591mm, n1xH-m 11 xh=56mm, 56mm 11 xW1+(m 11 -1)xW2=75mm; therefore, the sum of the sizes of the m 11 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. Wherein, W=m 11 xW1+(m 11 -1)xW2.

[0192] Therefore, when the energy storage device 100 uses the connection structure during transportation, the sum of the sizes of the m 11 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, which should be understood as including the height of the used connection structure. That is, the sum of the sizes of the m 11 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 minus the sum of the heights of the used connection structures. Such a case also belongs to the case of the embodiments of claims 3 to 6 of the present application.

[0193] 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.

[0194] 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.

[0195] 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. The connecting structure further includes a connecting piece, one end of the connecting piece is connected to the first locking hole along the height direction Z of the box body 111, and the other end of the connecting piece is connected to the second locking hole along the height direction Z of the box body 111.

[0196] By adopting the above technical solution, the structure of the plurality of energy storage containers 110 after stacking becomes more stable, thereby effectively improving the transportation safety of the energy storage container 110 and the use safety of the energy storage device 100.

[0197] In some embodiments of the present application, the plurality of energy storage containers 110 includes 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 limiting part, the top of the box 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 box body 111.

[0198] The first limiting part and the second limiting part cooperate to form at least part of a limiting structure for limiting the relative position of two adjacent energy storage containers 110 along the height direction Z.

[0199] As an example, the first limiting part can be a first limiting hole, and the second limiting part can be a first limiting piece. The first limiting piece is inserted into the first limiting hole along the height direction Z of the box body 111.

[0200] 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.

[0201] 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 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.

[0202] By adopting the above technical solution, the relative position of the two energy storage containers 110 along a direction perpendicular to the height direction Z of the box body 111 is effectively limited, thereby effectively reducing the risk of relative movement of the two adjacent energy storage containers 110.

[0211] As an example, 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 the 20-foot standard container, the size of the box 111 along the height direction Z is smaller than the size of the 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, and the size of the box 111 along the width direction Y is the same as the size of a 30-foot standard container along the width direction Y, i.e., the width of the box 111 is the same as the width of the 30-foot standard container.

[0216] By adopting the technical solutions described above, the horizontal area occupied by the energy storage container 110 during transportation is consistent with that of a standard container, facilitating the transportation of the energy storage container 110.

[0217] In some embodiments of the present application, the size of the box 111 along the length direction X is smaller than the size of a standard container along the length direction X, and the size of the box 111 along the width direction Y is consistent with the size of the standard container along the width direction Y.

[0218] The size of the box 111 along the width direction Y being consistent with the size of a standard container along the width direction Y does not mean that the width of the box 111 is exactly equal to the width of the standard container, but can have a certain error within an error allowable range. For example, according to GB / T1413-2008 and GB / T 1413-2023, the difference between the size of the box 111 along the width direction Y and the size of the standard container along the width direction Y is within ±5mm.

[0219] It should be noted that in actual applications, the size of the box 111 along the length direction X, the size of the box 111 along the height direction Z, and the size of the box 111 along the width direction Y can correspond to the size of a standard container of a same standard size, or can correspond to the size of a standard container of different standard sizes.

[0225] As an example, the box 111 has a dimension along the width direction Y that is the same as a dimension along the width direction Y of a 10-foot standard shipping container, i.e., the width of the box 111 is the same as the width of a 10-foot standard shipping container, the box 111 has a dimension along the length direction X that is less than a dimension along the length direction X of a 20-foot standard shipping container, i.e., the length of the box 111 is less than the length of a 20-foot standard shipping container, and the box 111 has a dimension along the height direction Z that is less than a dimension along the height direction Z of a 30-foot standard shipping container, i.e., the height of the box 111 is less than the height of a 30-foot standard shipping container.

[0226] In some embodiments, the size of the box 111 along the length direction X is smaller than the size of a standard container along the length direction X, the size of the box 111 along the width direction Y is smaller than the size of the standard container along the width direction Y, and the size of the box 111 along the height direction Z is the same as the size of another standard container along the height direction Z.

[0227] For example, the size of the box 111 along the length direction X is smaller than the size of a 20-foot standard container along the length direction X, the size of the box 111 along the width direction Y is smaller than the size of the 20-foot standard container along the width direction Y, and the size of the box 111 along the height direction Z is the same as the size of a 30-foot standard container along the height direction Z.

[0229] For example, 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, the size of the box 111 along the length direction X is smaller than the size of the 20-foot standard container along the length direction X, and the size of the box 111 along the height direction Z is smaller than the size of the 20-foot standard container along the height direction Z.

[0230] 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 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 system 1000 using the above energy storage device 100.

[0231] In some embodiments of the present application, 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.

[0232] In some embodiments, the energy storage device 100 includes at least four energy storage containers 110 , and the number of energy storage containers 110 in the energy storage device 100 is an integer multiple of 2.

[0233] 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.

[0234] 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.

[0235] 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.

[0236] 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.

[0237] 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.

[0238] It can be m 21m2 < m, the sum of the lengths of the m2 energy storage containers 110 is equal to the sum of the lengths of the n2 standard containers. 21 For example, m2 = 8, m = 5, n2 = 3; wherein the 5 energy storage containers 110 can be any 5 of the 8 energy storage containers 110, and the sum of the lengths of the 5 energy storage containers 110 is equal to the length of one standard container.

[0239] m2 = m, the sum of the lengths of the m2 energy storage containers 110 is equal to the sum of the lengths of the n2 standard containers. 21 For example, m2 = 2, m = 2, n2 = 1; wherein the sum of the lengths of the 2 energy storage containers 110 is equal to the length of one standard container. 21 For example, m2 = 2, m = 2, n2 = 1; wherein the sum of the lengths of the 2 energy storage containers 110 is equal to the length of one standard container.

[0240] The length of the energy storage container 110 can be the same, that is, the length of the energy storage container 110 can be m 21 times the sum of the lengths of the n2 standard containers along the length direction X, that is, the sum of the lengths of the m 21 energy storage containers 110 is equal to the sum of the lengths of the n2 standard containers along the length direction X. In this way, when n2 is 1, the m 21 energy storage containers 110 can form the length of one standard container along the length direction X, which is convenient for land transportation and sea transportation in the size of one standard container; when n2 is an integer greater than 1, the m 21 energy storage containers 110 can form the length of n2 standard containers along the length direction X, which is also convenient for transportation in the size of a standard container. When the size of the standard container is transported, the transportation cost can be greatly reduced.

[0241] Alternatively, the lengths of the m 21 energy storage containers 110 along the length direction X can be different, but at least the sum of the lengths of the m 21 energy storage containers 110 along the length direction X is equal to the length of n2 standard containers along the length direction X. In this way, the m 21 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, which greatly facilitates transportation and reduces transportation cost.

[0242] In the embodiments of the present application, the sum of the lengths of the m 21 energy storage containers 110 is equal to the sum of the lengths of the n2 standard containers along the length direction X, which means that the m 21The sum of the sizes of the m number of energy storage containers 110 along the length direction X is approximately equal to the sum of the sizes of the n2 number of standard containers along the length direction X. When the size difference between the sum of the sizes of the m number of energy storage containers 110 along the length direction X and the sum of the sizes of the n2 number of standard containers along the length direction X is within the above tolerance range, it can be considered that the sizes are approximately equal. 21 The size difference between the sum of the sizes of the m number of energy storage containers 110 along the length direction X and the sum of the sizes of the n2 number of standard containers along the length direction X is within the above tolerance range, it can be considered that the sizes are approximately equal.

[0243] Alternatively, due to manufacturing errors, the sum of the sizes of the m number of 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 number of energy storage containers 110 along the length direction X is equal to the sum of the sizes of the n2 number of standard containers along the length direction X plus m 21 ×W3. 21 The sum of the sizes of the m number of energy storage containers 110 along the length direction X is equal to the sum of the sizes of the n2 number of standard containers along the length direction X plus m 21 ×W3. 21 The sum of the sizes of the m number of energy storage containers 110 along the length direction X is equal to the sum of the sizes of the n2 number of standard containers along the length direction X plus m 21 ×W3.

[0244] As an example, m 21 =2, n2=1, the length l of the energy storage container 110 is 3027mm, the length L of the corresponding standard container is 6058mm, n2×L-m 21 ×l=4mm, 4mm 21 ×W3=10mm; therefore, the sum of the sizes of the m number of energy storage containers 110 along the length direction X is equal to the sum of the sizes of the n2 number of standard containers along the length direction X. 21 The sum of the sizes of the m number of energy storage containers 110 along the length direction X is equal to the sum of the sizes of the n2 number of standard containers along the length direction X.

[0245] The m 31 number of energy storage containers 110 in the m3 rows of energy storage containers 110 refers to any m 31 number of energy storage containers 110 in the m3 rows of energy storage containers 110. For example, the energy storage device 100 includes 8 energy storage containers 110, every 2 energy storage containers 110 are arranged into a row along the length direction X, and 4 rows of energy storage containers 110 are stacked along the height direction Z. If m 31 =2, the 2 rows of energy storage containers 110 can be the first row and the second row, or the first row and the third row, or the second row and the fourth row.

[0246] The m 31 number of energy storage containers 110 in the m3 rows of energy storage containers 110 refers to any m 31n3=3; wherein, the 5 rows of energy storage containers 110 can be any 5 rows of 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 1 standard container.

[0247] m can also be 31 m3, and the sum of the sizes of the m3 energy storage containers 110 along the height direction Z is equal to the sum of the sizes of the n3 standard containers along the height direction Z. For example, m3=2, m 31 m3, n3=1, and the sum of the heights of the 2 rows of energy storage containers 110 is equal to the height of 1 standard container.

[0248] m can be 31 The sizes of the rows of energy storage containers 110 along the height direction Z are the same, that is, the size of 1 row of energy storage containers 110 along the height direction Z can be m 31 of the sum of the sizes of the n3 standard containers along the height direction Z, that is, m 31 The sum of the sizes of the rows of energy storage containers 110 along the height direction Z is the sum of the sizes of the n3 standard containers along the height direction Z. In this way, when n3 is 1, m 31 The rows of energy storage containers 110 can form the size of 1 standard container along the height direction Z, which is convenient for assembling into the size of 1 standard container for land transportation and sea transportation; when n3 is an integer greater than 1, m 31 The rows of energy storage containers 110 can form the size of n3 standard containers along the height direction Z, which can also be convenient for 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.

[0288] As an example, the energy storage device 100 includes 4 energy storage containers 110, and in the process of assembling the energy storage device 100, every 2 energy storage containers 110 can be arranged in a column along the width direction Y of the box body 111, and then 2 columns of energy storage containers 110 are stacked along the height direction Z of the box body 111.

[0289] As an example, the energy storage device 100 includes 6 energy storage containers 110, and in the process of assembling the energy storage device 100, every 2 energy storage containers 110 can be arranged in a column along the width direction Y of the box body 111, and then 3 columns of energy storage containers 110 are stacked along the height direction Z of the box body 111.

[0292] 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.

[0293] 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 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 widths of the five energy storage containers 110 is equal to the width of one standard container.

[0294] It can also be m 41 = m4, the sum of the dimensions of 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 = 2, m 41 =m4, n4=1, the sum of the widths of the two energy storage containers 110 is equal to the width of one standard container.

[0295] The dimensions of the energy storage container 110 along the width direction Y may be the same, that is, the dimension of the energy storage container 110 along the width direction Y may be m times the sum of the dimensions of n4 standard containers along the width direction Y. 41 One-tenth, that is, m 41 The sum of the dimensions of the energy storage containers 110 along the width direction Y is the sum of the dimensions of n4 standard containers along the width direction Y. Thus, when n4 is 1, m 41The energy storage containers 110 can form the size of a standard container along the width direction Y, which is convenient for assembly into the size of a standard container for land and sea transportation; when n4 is an integer greater than 1, m 41 The energy storage containers 110 can be combined into n4 standard containers along the width direction Y, and can also be conveniently transported in the size of a standard container. When transported in the size of a standard container, transportation costs can be greatly reduced.

[0296] Optionally, it can also be m 41 The dimensions of the energy storage containers 110 along the width direction Y are different, but at least m of them need to be set. 41 The sum of the dimensions of the energy storage containers 110 along the width direction Y is the dimensions of n4 standard containers along the width direction Y. 41 The energy storage containers 110 are assembled into one or more standard containers along the width direction Y, which greatly facilitates transportation and reduces transportation costs.

[0297] In the embodiment of the present application, m 41 The sum of the dimensions of n 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 means: 41 The sum of the dimensions of the energy storage containers 110 along the width direction Y is approximately equal to the sum of the dimensions of n4 standard containers along the width direction Y. 41 When 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.

[0298] Optionally, due to manufacturing errors, m 41 The sum of the dimensions of the energy storage containers along the width direction Y can be m 41 A manufacturing error W5, W5 ≤ 5mm, that is, m 41 The sum of the dimensions of n4 energy storage containers 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 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.

[0299] As an example, m 41 =2, n4=1, the width k of the energy storage container is 1215mm, the corresponding width K of the standard container is 2438mm, n4×Km 41 ×k=8mm,8mm<m 41 ×W5=10mm; therefore, m 41The sum of the dimensions of n4 energy storage containers along the width direction Y is equal to the sum of the dimensions of n4 standard containers along the width direction Y.

[0300] 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.

[0301] 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.

[0302] It can also be m 51 = m5, the sum of the dimensions of m5 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 = 2, m 51 =m5, n5=1, the sum of the heights of the two rows of energy storage containers 110 is equal to the height of one standard container.

[0303] It can be m 51 The dimensions of the energy storage containers 110 in a row along the height direction Z are the same, that is, the dimension of one row of energy storage containers 110 along the height direction Z can be m times the sum of the dimensions of n5 standard containers along the height direction Z. 51 One-tenth, that is, m 51 The sum of the dimensions of the energy storage container 110 in the height direction Z is the sum of the dimensions of n5 standard containers in the height direction Z. Thus, when n5 is 1, m 51 The energy storage container 110 can form 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 n5 is an integer greater than 1, m 51 The row of energy storage containers 110 can be formed into n5 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, transportation costs can be greatly reduced.

[0304] Optionally, m 51 The size of the column energy storage container 110 along the height direction Z is different, but at least m 51 The sum of the size of the column energy storage container 110 along the height direction Z is n5times the size of the standard container along the height direction Z. In this way, the sum of the size of the m 51 The column energy storage container 110 is assembled into one or more standard containers along the height direction Z, which greatly facilitates transportation and reduces transportation costs.

[0305] In the embodiments of the present application, m 51 The sum of the size of the column energy storage container 110 along the height direction Z is equal to n5times the sum of the size of the standard container along the height direction Z, which means that m 51 The sum of the size of the column energy storage container 110 along the height direction Z is approximately equal to n5times the sum of the size of the standard container along the height direction Z. When m 51 The sum of the size of the column energy storage container 110 along the height direction Z is approximately equal to n5times the sum of the size of the standard container along the height direction Z. When m

[0306] Optionally, due to manufacturing errors, m 51 The sum of the size of the column energy storage container 110 along the height direction Z can have a manufacturing error W1, W1≤5mm, that is, m 51 The sum of the size of the column energy storage container 110 along the height direction Z can have a manufacturing error W1, W1≤5mm, that is, m 51 The sum of the size of the column energy storage container 110 along the height direction Z is equal to n5times the sum of the size of the standard container along the height direction Z, which can also be m 51 The sum of the size of the column energy storage container 110 along the height direction Z is equal to n5times the sum of the size of the standard container along the height direction Z, which can also be m 51 The sum of the size of the column energy storage container 110 along the height direction Z is equal to n5times the sum of the size of the standard container along the height direction Z, which can also be m

[0307] As an example, m 51 =2, n5=1, the height h of the energy storage container 110 is 1293mm, and the height H of the corresponding standard container is 2591mm, n5×H-m 51 ×h=5mm, 5mm 51 ×W1=10mm; therefore, m 51 The sum of the size of the column energy storage container 110 along the height direction Z is equal to n5times the sum of the size of the standard container along the height direction Z.

[0308] By adopting the above technical solution, m 41 The size of the column energy storage container 110 along the width direction Y of the container body 111 is n4times the size of the standard container along the width direction Y, m 51The size of the column energy storage container 110 along the height direction Z of the box body 111 is n5 times the size of a standard container along the height direction Z. When the plurality of energy storage containers 110 are stacked, the space occupied by the plurality of energy storage containers 110 is the same as the space occupied by at least one standard container, thereby improving the utilization rate of the space for placing the energy storage containers 110, facilitating full use of the length space and height space during transportation, reducing the space waste of the energy storage containers 110 during transportation, and reducing the transportation cost of the energy storage containers 110, thereby further reducing the use cost of the energy storage system 1000 using the energy storage device 100.

[0309] In some embodiments of the present application, m 41 = 2, n4 = 1, m 51 = 2, n5 = 1.

[0339] By adopting the above technical solutions, the energy storage container 110 will not exceed the size of a standard container along the length direction X in the process of transportation, nor will it exceed the size of a standard container along the width direction Y 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 system 1000 adopting the above energy storage device 100.

[0340] 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 in a row along the length direction X of the box 111, m7 rows of energy storage containers 110 are arranged in an array structure along the width direction Y of the box 111, and m8 array structures are stacked along the height direction Z of the box 111, wherein m6, m7 and m8 are positive integers greater than or equal to 2.

[0341] 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.

[0342] As an example, the energy storage device 100 includes 8 energy storage containers 110, in the process of assembling the energy storage device 100, 2 energy storage containers 110 can be arranged in a row along the length direction X of the box 111, 2 rows of energy storage containers 110 can be arranged in an array structure along the width direction Y of the box 111, and 2 array structure energy storage containers 110 can be stacked along the height direction Z of the box 111.

[0343] As an example, the energy storage device 100 includes 12 energy storage containers 110, in the process of assembling the energy storage device 100, 3 energy storage containers 110 can be arranged in a row along the length direction X of the box 111, 2 rows of energy storage containers 110 can be arranged in an array structure along the width direction Y of the box 111, and 2 array structure energy storage containers 110 can be stacked along the height direction Z of the box 111.

[0344] By adopting the technical scheme, more energy storage containers 110 can be configured in the case of the same land area of the energy storage device 100, the area energy density of the energy storage system 1000 is further improved, and thus the performance of the energy storage system 1000 is further improved.

[0345] In some embodiments of the present application, m6 energy storage containers 110 in the m 61 th row of energy storage containers 110 have a total length along the length direction X of the box body 111 equal to a total length along the length direction X of n6 standard containers, n6 being a positive integer less than m 61 In some embodiments of the present application, m7 energy storage containers 110 in the m 71 th row of energy storage containers 110 have a total width along the width direction Y of the box body 111 equal to a total width along the width direction Y of n7 standard containers, n7 being a positive integer less than m 71 In some embodiments of the present application, m8 array structures in the m 81 th row of array structures have a total height along the height direction Z of the box body 111 equal to a total height along the height direction Z of n8 standard containers, n8 being a positive integer less than m 81 .

[0346] In some embodiments of the present application, m6 energy storage containers 110 in the m 61 th row of energy storage containers 110 refer to any m 61 energy storage containers 110 in the m6 energy storage containers 110. For example, the energy storage device 100 has 8 energy storage containers 110, which are a first energy storage container, a second energy storage container, a third energy storage container, a fourth energy storage container, a fifth energy storage container, a sixth energy storage container, a seventh energy storage container, and an eighth energy storage container. If m 61 = 2, the two energy storage containers 110 can be the first energy storage container and the third energy storage container, the second energy storage container and the fourth energy storage container, or the fifth energy storage container and the eighth energy storage container.

[0347] In some embodiments of the present application, m 61 may be less than m6, and a total length along the length direction X of part of the m6 energy storage containers 110 is equal to a total length along the length direction X of n6 standard containers. For example, m6 = 8, m 61 = 5, and n6 = 3. The five energy storage containers 110 can be any five energy storage containers 110 in the eight energy storage containers 110, and the total length of the five energy storage containers 110 is equal to the length of one standard container.

[0348] In some embodiments of the present application, m 61m6, the sum of the sizes of the m6 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. For example, m6 = 2, m 61 n6 = 1, the sum of the lengths of the m6 energy storage containers 110 is equal to the length of the n6 standard container.

[0349] The sizes of the energy storage containers 110 along the length direction X can be the same, that is, the sizes of the energy storage containers 110 along the length direction X can be m 61 times the sum of the sizes of the n6 standard containers along the length direction X. That is, m 61 times the sum of the sizes 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 size of the n6 standard container along the length direction X, facilitating the assembly into the size of the n6 standard container for land transportation and sea transportation; when n6 is an integer greater than 1, the m 61 energy storage containers 110 can form the size of the n6 standard container along the length direction X, which can also facilitate transportation in the size of the standard container. When the size of the standard container is assembled for transportation, the transportation cost can be greatly reduced.

[0350] Alternatively, the sizes of the m 61 energy storage containers 110 along the length direction X can be different, but at least the sum of the sizes of the m 61 energy storage containers 110 along the length direction X is equal to the size of the n6 standard container along the length direction X. In this way, the m 61 energy storage containers 110 with different sizes along the length direction X can be assembled into the size of one or more standard containers along the length direction X, greatly facilitating transportation and reducing transportation cost.

[0351] In the embodiments of the present application, the sum of the sizes of the m 61 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 means that the sum of the sizes of the m 61 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 61 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.

[0352] Alternatively, due to manufacturing errors, the sum of the sizes of the m 61 energy storage containers 110 along the length direction X can be m 61A manufacturing error W3, W3 ≤ 5mm, that is, m 61 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 n6 standard containers along the length direction X, which can also be m 61 The sum of the dimensions of the energy storage containers 110 along the length direction X plus m 61 W3 is equal to the sum of the dimensions of n6 standard containers along the length direction X.

[0353] As an example, m 61 =2, n6=1, the length l of the energy storage container 110 is 3027 mm, the length L of the corresponding standard container is 6058 mm, n6×Lm 61 ×l=4mm,4mm<m 61 ×W3=10mm; therefore, m 61 The sum of the dimensions of n6 energy storage containers 110 along the length direction X is equal to the sum of the dimensions of n6 standard containers along the length direction X.

[0354] m7 row energy storage container 110 m 71 The row energy storage container 110 refers to any m in the m7 row energy storage container 110 71 For example, the energy storage device 100 has 4 rows of energy storage containers 110. 71 =2, the two rows of energy storage containers 110 can be the first row and the third row, the first row and the second row, or the second row and the fourth row.

[0355] It can be m 71 Less than m7, the sum of the dimensions of some energy storage containers 110 in the m7 row of energy storage containers 110 along the width direction Y is equal to the sum of the dimensions of n7 standard containers along the width direction Y. For example, m7=8, m 71 =5, n7=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 widths of the 5 rows of energy storage containers 110 is equal to the width of 1 standard container.

[0356] It can also be m 71 = m7, the sum of the dimensions of m7 rows of energy storage containers 110 along the width direction Y is equal to the sum of the dimensions of n7 standard containers along the width direction Y. For example, m7 = 2, m 71 =m7, n7=1, the sum of the widths of the two rows of energy storage containers 110 is equal to the width of one standard container.

[0357] The dimensions of the energy storage container 110 along the width direction Y may be the same, that is, the dimension of the energy storage container 110 along the width direction Y may be m times the sum of the dimensions of n7 standard containers along the width direction Y.71 m 71 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 n7 standard containers along the width direction Y. In this way, when n7 is 1, m 71 The energy storage containers 110 along the width direction Y can be assembled to form the dimensions of 1 standard container, which is convenient for land and sea transportation in the dimensions of 1 standard container; when n7 is an integer greater than 1, m 71 The energy storage containers 110 along the width direction Y can be assembled to form the dimensions of n7 standard containers, which is also convenient for transportation in the dimensions of standard containers. When the assembled dimensions of standard containers are transported, the transportation cost can be greatly reduced.

[0358] Alternatively, m 71 The energy storage containers 110 along the width direction Y can have different dimensions, but at least m 71 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 n7 standard containers along the width direction Y. In this way, the dimensions of the energy storage containers 110 along the width direction Y can also be different, and m 71 The energy storage containers 110 along the width direction Y can be assembled to form the dimensions of 1 or more standard containers along the width direction Y, which greatly facilitates transportation and reduces transportation cost.

[0359] In the embodiments of the present application, m 71 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 n7 standard containers along the width direction Y, which means that m 71 The sum of the dimensions of the energy storage containers 110 along the width direction Y is approximately equal to the sum of the dimensions of n7 standard containers along the width direction Y. When m 71 When the difference between the sum of the dimensions of the energy storage containers 110 along the width direction Y and the sum of the dimensions of n7 standard containers along the width direction Y is within the above tolerance range, it can be considered that the dimensions are approximately equal.

[0360] Alternatively, due to manufacturing errors, m 71 The sum of the dimensions of the energy storage containers 110 along the width direction Y can have a manufacturing error of m 71 W5, W5≤5mm, that is, m 71 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 n7 standard containers along the width direction Y, which can also be m 71 The sum of the dimensions of the energy storage containers 110 along the width direction Y plus m 71 W5 is equal to the sum of the dimensions of n7 standard containers along the width direction Y.

[0361] As an example, m 71= 2, n7 = 1, the width k of the energy storage container 110 is 1215 mm, and the width K of the corresponding standard container is 2438 mm, n7 x K - m 71 x k = 8 mm, 8 mm < m 71 x W5 = 10 mm; therefore, m 71 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 the n7 standard containers along the width direction Y.

[0362] The m 81 array structure refers to any m 81 array structure 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.

[0363] The m 81 may be less than m8, and the sum of the dimensions of several array structures in 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 = 8, m 81 = 5, n8 = 3; wherein 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 1 standard container.

[0364] The m 81 may also 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, m 81 = m8, n8 = 1, and the sum of the heights of the 2 array structures is equal to the height of 1 standard container.

[0365] The m 81 array structures along the height direction Z can have the same dimension, that is, the dimension of 1 array structure along the height direction Z can be m 81 times the sum of the dimensions of the n8 standard containers along the height direction Z, that is, the sum of the dimensions of the m 81 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. In this way, when n8 is 1, the m 81 array structures can form the dimension of 1 standard container along the height direction Z, facilitating land transportation and sea transportation in the form of 1 standard container; when n8 is an integer greater than 1, the m 81The array structure can be composed of the size of n8 standard containers along the height direction Z, and can be conveniently transported in the size of the standard container. When the array structure is composed of the size of the standard container for transportation, the transportation cost can be greatly reduced.

[0366] Alternatively, m 81 The array structure along the height direction Z has different sizes, but at least the sum of the sizes of m 81 The array structure along the height direction Z has different sizes, but at least the sum of the sizes of m 81 The array structure along the height direction Z has different sizes, but at least the sum of the sizes of m

[0367] In the embodiment of the present application, the sum of the sizes of m 81 The sum of the sizes of m 81 The sum of the sizes of m 81 The sum of the sizes of m

[0368] Alternatively, due to manufacturing errors, the sum of the sizes of m 81 The sum of the sizes of m 81 The sum of the sizes of m 81 The sum of the sizes of m 81 The sum of the sizes of m 81 The sum of the sizes of m
