Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The following is for reference. Figures 1-5 Description of support member 100 according to an embodiment of the present utility model.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the support member 100 according to an embodiment of the present utility model includes a first plate 1, a second plate 2 and an inclined plate 3.

[0030] Specifically, such as Figures 1-3 As shown, the first plate 1 can be used to connect with the battery pack 7. One end of the first plate 1 in the length direction is provided with a first mounting part 11. The second plate 2 is parallel to the first plate 1. Along the length direction of the first plate 1, the first plate 1 and the second plate 2 are spaced apart. The second plate 2 is provided with a second mounting part 21. The two ends of the inclined plate 3 are respectively connected to the ends of the first plate 1 and the second plate 2 that are close to each other. In the direction from the first plate 1 to the second plate 2, the inclined plate 3 is inclined toward the second plate 2.

[0031] The first plate 1 can be detachably connected to the battery pack 7. For example, the first plate 1 and the battery pack 7 can be connected by fasteners, which can ensure the connection stability between the support 100 and the battery pack 7, and facilitate the disassembly of the first plate 1 and the battery pack 7, which can provide convenience for subsequent maintenance and assembly.

[0032] By connecting the first plate 1 to the battery pack 7, the support member 100 can fix and connect the battery pack 7. The first mounting portion 11 of one support member 100 is connected to the second mounting portion 21 of another support member 100, thus connecting the two support members 100 and fixing the two battery packs 7 together. By connecting multiple support members 100 sequentially in the above manner, multiple battery packs 7 can be fixedly connected. The support member 100, with its first mounting portion 11 and second mounting portion 21, facilitates the fixed connection of multiple battery packs 7 to form an energy storage system 300. While ensuring the connection stability between multiple battery packs 7, the difficulty of fixing and connecting multiple battery packs 7 can be reduced, thereby improving the structural stability and assembly efficiency of the energy storage system 300.

[0033] For example, the support member 100 is connected to the battery pack 7, and multiple support members 100 are sequentially connected in the vertical direction to form a bracket assembly 6. In two adjacent support members 100, the first plate 1 of the upper support member 100 is attached to the second plate 2 of the lower support member 100, and the first mounting part 11 of the upper support member 100 is connected to the second mounting part 21 of the lower support member 100. In the vertical direction, multiple support members 100 correspond one-to-one with multiple battery packs 7, and each support member 100 is connected to the corresponding battery pack 7. In this way, multiple battery packs 7 are arranged and fixedly connected in the vertical direction, thereby forming an energy storage system 300.

[0034] like Figure 1 In the example shown, the first plate 1 extends along the X direction, and the length direction of the first plate 1 is... Figure 1 The X-direction shown is the thickness direction of the first plate 1. Figure 1 The Y direction is shown, where the X direction is perpendicular to the Y direction. Along the X direction, the first plate 1, the inclined plate 3, and the second plate 2 are connected in sequence. By tilting the inclined plate 3, the first plate 1 and the second plate 2 are offset in the Y direction.

[0035] When multiple support members 100 are connected to each other, the inclined plate 3 and the second plate 2 of the lower support member 100 can form a clearance space for the first plate 1 of the upper support member 100, so that the first plate 1 of the upper support member 100 and the first plate 1 of the lower support member 100 can be aligned vertically, avoiding the multiple support members 100 and the multiple battery packs 7 from being tilted in the vertical direction, and facilitating the connection between the support member 100 and the battery pack 7.

[0036] This application enables the stacking and fixed connection of multiple battery packs 7 through the connection of multiple support members 100, thereby forming an energy storage system 300. The support members 100 have a simple structure and uniform specifications, facilitating mass production. Replacing existing cabinets or racks with support members 100 can significantly shorten the processing cycle and reduce production costs. Furthermore, the support members 100 occupy very little space, facilitating transportation and effectively improving the utilization rate of transportation space, thereby improving transportation efficiency.

[0037] In addition, the multiple support components 100 and the support components 100 and the battery pack 7 can be quickly disassembled, which solves the problem of inconvenience in moving and transporting existing cabinets or racks. It can be applied to usage scenarios where the installation location of the energy storage system 300 needs to be moved frequently, thereby improving the flexibility and applicability of the support components 100 and the energy storage system 300.

[0038] According to the embodiment of this utility model, the support member 100 is provided with a first plate 1, a second plate 2, and an inclined plate 3. The first plate 1 is used to connect with the battery pack 7. One end of the first plate 1 in the length direction is provided with a first mounting part 11, and the second plate 2 is provided with a second mounting part 21. This allows the support member 100 to fix and connect the battery pack 7. By connecting the first mounting part 11 and the second mounting part 21, multiple support members 100 can be connected together, thereby facilitating the fixed connection of multiple battery packs 7 to form an energy storage system 300. The inclined plate 3 is inclined and its two ends are respectively connected to the ends of the first plate 1 and the second plate 2 that are close to each other, which facilitates the alignment of the first plates 1 of multiple support members 100, so as to facilitate the connection of the support members 100 with the battery pack 7. The support member 100 has a simple structure, which can significantly shorten the processing cycle and reduce production costs. Moreover, the support member 100 occupies very little space, which is convenient for transportation and can effectively improve the utilization rate of transportation space, thereby improving transportation efficiency. It is suitable for application scenarios that require frequent relocation of the installation position of the energy storage system 300.

[0039] In one specific embodiment, the battery pack 7 has a housing 71 with a first mounting hole. A first nut is fixed inside the housing 71, which can be a press-fit nut that is riveted to the inside of the housing 71. The first nut is opposite to the first mounting hole. A second mounting hole 13 is provided on the first plate 1 to mate with the first mounting hole. An operator can pass a bolt or other first fastener through the second mounting hole 13 and the first mounting hole in sequence, thereby fixing the first fastener inside the first nut, thus achieving a fixed connection between the support member 100 and the battery pack 7. The structure is simple and easy to implement, and assembly is convenient.

[0040] Furthermore, there are multiple first mounting holes and second mounting holes 13 in a one-to-one correspondence, and the multiple second mounting holes 13 are spaced apart along the length direction of the first plate 1. This allows the first plate 1 to connect to the battery pack 7 at multiple points, enhancing the connection stability between the support member 100 and the battery pack 7, thereby improving the structural reliability of the energy storage system 300. Specifically, the number of first mounting holes and second mounting holes 13 can be 2, 3, 4, 5, 6, etc.

[0041] Furthermore, the first mounting hole and the second mounting hole 13 have the same diameter, which can be 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, etc.

[0042] Furthermore, the second mounting hole 13 is a slotted hole, which can provide adjustment allowance. During the assembly process of the support 100 and the battery pack 7, it can compensate for the size and position errors of the first mounting hole and the second mounting hole 13, thereby compensating for the manufacturing and installation errors of the support 100 and the battery pack 7, reducing the assembly difficulty of the support 100 and the battery pack 7, and thus helping to improve production and assembly efficiency.

[0043] In some embodiments, the first mounting part 11 and the second mounting part 21 are detachably connected. For example, the first mounting part 11 and the second mounting part 21 can be connected by fasteners, which can ensure the connection stability between multiple support members 100, thereby ensuring the reliability and stability of the bracket assembly 6 and the energy storage system 300, and also facilitate the disassembly of the support members 100, which can provide convenience for maintenance and transportation.

[0044] In one specific embodiment, the first mounting part 11 includes a first connecting hole 111, which is located at one end of the first plate 1 away from the second plate 2 along its length. A second nut is fixed to one side of the first plate 1 along its thickness. Specifically, the second nut can be a press-fit nut that is pressed onto the first plate 1. The second nut is opposite to the first connecting hole 111. The second mounting part 21 includes a second connecting hole 211. When the two support members 100 are connected to each other, the second connecting hole 211 on the lower support member 100 is opposite to the first connecting hole 111 on the upper support member 100. The operator can pass a bolt or other second fastener through the second connecting hole 211 and the first connecting hole 111 in sequence, and then fix the second fastener in the second nut, thereby realizing the fixed connection between the two support members 100. The structure is simple and easy to implement, and the assembly is convenient.

[0045] Furthermore, there are multiple first connecting holes 111 and second connecting holes 211 that correspond one-to-one, and the multiple first connecting holes 111 are along the width direction of the first plate 1 (e.g., Figure 1As shown in the Z direction, multiple second connecting holes 211 are spaced apart along the width direction of the first plate 1, thereby allowing the two support members 100 to be connected at multiple points, which can enhance the connection stability between the support members 100, thereby improving the structural stability and reliability of the bracket assembly 6 and the energy storage system 300. Specifically, the number of first connecting holes 111 and second connecting holes 211 can be 2, 3, 4, 5, 6, etc.

[0046] Furthermore, the first connecting hole 111 and the second connecting hole 211 have the same diameter, which can be 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, etc.

[0047] Furthermore, the second connecting hole 211 is a waist hole, which can provide adjustment margin. During the assembly of multiple support components 100, it can compensate for the size and position errors of the first connecting hole 111 and the second connecting hole 211, thereby compensating for the manufacturing and installation errors of the support component 100, reducing the assembly difficulty of the bracket assembly 6, and thus helping to improve the production and assembly efficiency of the bracket assembly 6 and the energy storage system 300.

[0048] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the support member 100 also includes a support portion 4, which is disposed on one side of the first plate 1 in the thickness direction and at one end of the first plate 1 in the length direction opposite to the second plate 2, for supporting the battery pack 7. It can be understood that the support portion 4 can support the battery pack 7, reduce the stress at the connection between the first plate 1 and the battery pack 7, thereby enhancing the connection stability between the battery pack 7 and the first plate 1, and thus improving the stability and reliability of the energy storage system 300.

[0049] For example, when the support member 100 is applied to the energy storage system 300, the length direction of the first plate 1 is vertical, and the battery pack 7 is connected to the first plate 1. At this time, the support part 4 is located below the battery pack 7 and can support the battery pack 7. The support part 4 can bear part of the weight of the battery pack 7, thereby reducing the stress at the connection between the first plate 1 and the battery pack 7, which is conducive to enhancing the connection stability between the battery pack 7 and the first plate 1, and thus improving the stability and reliability of the energy storage system 300.

[0050] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the support part 4 includes a first sub-plate 41, one end of which is connected to the first plate 1. The first sub-plate 41 and the first plate 1 are at an angle to each other. The ends of the first sub-plate 41 and the first plate 1 are spaced apart in the length direction. The first mounting part 11 is located on the side of the first sub-plate 41 that is away from the second plate 2.

[0051] It is understandable that the first sub-board 41 can be set perpendicular to the first board 1. The battery pack 7 is generally a cuboid structure. The first sub-board 41, which is set perpendicular to the first board 1, can fit more closely to the battery pack 7 and better support the battery pack 7, thereby enhancing the connection stability between the battery pack 7 and the first board 1, and thus improving the stability and reliability of the energy storage system 300.

[0052] The first sub-board 41 is spaced apart from the end of the first board 1 along its length, which makes it easy for the first mounting part 11 and the battery pack 7 to be separated on both sides of the first sub-board 41 along the length of the first board 1. This avoids interference between the connection of the first mounting part 11 and the battery pack 7, and the structure is reasonably arranged.

[0053] Furthermore, when the support member 100 is applied to the energy storage system 300, multiple support members 100 are sequentially connected in the vertical direction to form a bracket assembly 6. The first mounting portion 11 of the upper support member 100 is connected to the second mounting portion 21 of the lower support member 100 in a pair of adjacent support members 100. Therefore, the distance between the surface of the first sub-plate 41 that is in contact with the battery pack 7 and the end of the first plate 1 that is away from the second plate 2 in the length direction is approximately the same as the distance between two adjacent battery packs 7. In specific implementations, the distance between two adjacent battery packs 7 can be determined based on the type of battery pack 7 and the length of the wiring harnesses connected in parallel or series among multiple battery packs 7, thereby determining the distance between the surface of the first sub-plate 41 that is in contact with the battery pack 7 and the end of the first plate 1 that is away from the second plate 2 in the length direction.

[0054] Preferably, such as Figure 2 In the example shown, along the length of the first plate 1, the distance between the surface of the first sub-plate 41 near the second plate 2 and the end of the first plate 1 away from the second plate 2 is h, and satisfies 20mm ≤ h ≤ 30mm. This ensures a suitable spacing between adjacent battery packs 7, facilitating matching the length of wiring harnesses connected in parallel or series between multiple battery packs 7. Specifically, h can be 20mm, 22mm, 24mm, 26mm, 28mm, 30mm, etc.

[0055] In some embodiments of this utility model, such as Figures 1-3 As shown, the first sub-plate 41 has a protrusion 411 at one end near the first plate 1, and the first plate 1 has a fixing hole 12 that mates with the protrusion 411. In the specific assembly process, the first sub-plate 41 and the first plate 1 can be connected by inserting the protrusion 411 into the fixing hole 12. The operation is simple and convenient, which helps to improve the assembly efficiency of the support 100.

[0056] Furthermore, there are multiple protrusions 411 and fixing holes 12 in a one-to-one correspondence. The protrusions 411 are spaced apart along the width direction of the first sub-plate 41, and the fixing holes 12 are spaced apart along the width direction of the first plate 1. The width direction of the first sub-plate 41 is consistent with the width direction of the first plate 1. This further enhances the connection stability between the first sub-plate 41 and the first plate 1, thereby improving the structural strength of the support member 100. Specifically, the number of protrusions 411 and fixing holes 12 can be 2, 3, 4, 5, 6, etc.

[0057] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, along the thickness direction of the first plate 1, the length of the protrusion 411 is less than or equal to the depth of the fixing hole 12. It is understood that the protrusion 411 will not pass through the fixing hole 12 and protrude from the surface of the first plate 1 facing away from the first sub-plate 41, thus keeping the plane of the first plate 1 facing away from the first sub-plate 41 flush. When the support member 100 is applied to the energy storage system 300, multiple support members 100 are sequentially connected in the vertical direction to form a bracket assembly 6. This facilitates the fit between the first plate 1 of the upper support member 100 and the second plate 2 of the lower support member 100, avoiding interference from the protrusion 411 on the connection between the first mounting part 11 and the second mounting part 21. The structural design is reasonable. This reduces the assembly difficulty between the first mounting part 11 and the second mounting part 21, resulting in a more stable and reliable connection between them, thereby enhancing the structural stability of the bracket assembly 6 and improving the stability and reliability of the energy storage system 300.

[0058] In some embodiments of this utility model, the first sub-plate 41 is welded to the first plate 1, which can further enhance the connection strength between the first sub-plate 41 and the first plate 1, thereby improving the support stability of the support part 4 on the battery pack 7, which is beneficial to improving the structural strength of the support member 100 and improving the reliability and stability of the energy storage system 300.

[0059] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the support part 4 also includes a second sub-plate 42 and a third sub-plate 43. The second sub-plate 42 is at an angle to the first plate 1. The second sub-plate 42 is connected to the first plate 1 and is located on the side of the first sub-plate 41 away from the second plate 2. The opposite ends of the third sub-plate 43 are respectively connected to the ends of the first sub-plate 41 and the second sub-plate 42 away from the first plate 1.

[0060] The first sub-plate 41, the second sub-plate 42, and the third sub-plate 43 are sequentially connected to the first plate 1 to form a U-shaped structure, which can achieve better bending and torsional stiffness, thereby effectively improving the structural strength and stability of the support part 4. This is beneficial to further improving the support stability of the support part 4 for the battery pack 7, thereby improving the reliability and stability of the energy storage system 300.

[0061] Preferably, the first sub-plate 41, the second sub-plate 42 and the third sub-plate 43 can be integrally processed by bending, which has high production efficiency and can enhance the structural stability of the support part 4.

[0062] In some embodiments, one end of the second sub-plate 42 is connected to one end of the first plate 1 that is opposite to the second plate 2 in the length direction. This facilitates the integral processing of the second sub-plate 42 and the first plate 1 through a bending process, which can reduce the processing difficulty, thereby improving production efficiency and effectively improving the connection strength between the second sub-plate 42 and the first plate 1.

[0063] Furthermore, the first sub-plate 41 and the third sub-plate 43 can be integrally processed by bending, and then the L-shaped second sub-plate 42 and the first plate 1, as well as the L-shaped first sub-plate 41 and the third sub-plate 43, are connected together, making the production and processing simple and quick.

[0064] In some embodiments of this utility model, such as Figures 1-3 As shown, the support member 100 also includes a guide plate 5. One end of the guide plate 5 is connected to the end of the second plate 2 away from the inclined plate 3, and the other end of the guide plate 5 extends obliquely towards the side of the second plate 2 away from the first plate 1 in the thickness direction. The guide plate 5 can play a guiding role. During the assembly process of the two support members 100, the lower end of the first plate 1 of the upper support member 100 can be guided by the guide plate 5 of the lower support member 100, so that the first plate 1 of the upper support member 100 and the second plate 2 of the lower support member 100 fit together, which can effectively reduce the assembly difficulty and thus improve the assembly efficiency.

[0065] In some embodiments of this utility model, the length of the guide plate 5 along the length direction of the first plate 1 is greater than or equal to 6.5 mm. The inclined guide plate 5 can be processed by bending the upper end of the first plate 1. If the length of the guide plate 5 is less than 6.5 mm, the size is too small, making it inconvenient for the clamping tools in the bending process to clamp the guide plate 5, and it will also affect the guiding effect of the guide plate 5. Making the length of the guide plate 5 along the length direction of the first plate 1 greater than or equal to 6.5 mm can effectively reduce the processing difficulty of the guide plate 5, thereby improving production efficiency, and can also ensure the guiding role of the guide plate 5 in the assembly process, thereby improving assembly efficiency. Of course, the length of the guide plate 5 cannot be too large, as it will easily lead to the guide plate 5 occupying too much space and thus easily interfering with other components.

[0066] Specifically, such as Figure 2 As shown in the example, in the longitudinal section perpendicular to the width direction of the first plate 1, the length of the guide plate 5 can be understood as the distance c from one end of the guide plate 5 connected to the second plate 2 to the other end. The length of the guide plate 5 can be 6.5mm, 7mm, 8mm, 9mm, 10mm, etc.

[0067] In some embodiments of this utility model, such as Figure 2 As shown, the thickness of the first plate 1 is 'a', and the distance between the first plate 1 and the second plate 2 along the thickness direction of the first plate 1 is 'b', satisfying: 0.5mm ≤ ba ≤ 1mm. That is, the distance between the first plate 1 and the second plate 2 along the thickness direction of the first plate 1 should be slightly greater than the thickness of the first plate 1. Thus, when the two support members 100 are connected to each other, the second plate 2 of the lower support member 100 can provide sufficient clearance for the first plate 1 of the upper support member 100, avoiding interference between the first plate 1 and the second plate 2. This facilitates the vertical alignment of the first plate 1 of the upper support member 100 and the first plate 1 of the lower support member 100, preventing the multiple support members 100 and the multiple battery packs 7 from being tilted in the vertical direction, and facilitating the connection between the support members 100 and the battery packs 7. Furthermore, it facilitates the fitting of the first plate 1 of the upper support member 100 with the second plate 2 of the lower support member 100, thereby reducing the assembly difficulty between the first mounting part 11 and the second mounting part 21, making the first mounting part 11 and the second mounting part 21 form a more stable and reliable connection, thereby enhancing the structural stability of the bracket assembly 6 and improving the stability and reliability of the energy storage system 300.

[0068] In some embodiments of this utility model, such as Figures 1-3 As shown, the support component 100 is a single piece, which can achieve higher structural strength and rigidity, thereby enhancing the structural stability of the support assembly 6 and improving the stability and reliability of the energy storage system 300.

[0069] In some embodiments, the support member 100 is a hot-dip galvanized steel part, specifically made of hot-dip galvanized steel sheet. The surface of the hot-dip galvanized steel part can be protected by a physical barrier formed by the zinc layer, thereby improving the corrosion resistance of the support member 100 and improving the reliability and stability of the support assembly 6 and the energy storage system 300.

[0070] In some embodiments, the thickness of the first plate 1 and the second plate 2 is 1.5mm-2mm, that is, the support member 100 can be processed by a metal plate with a thickness of 1.5mm-2mm, which can ensure the structural strength of the support member 100 and avoid excessive cost.

[0071] The following describes a battery cabinet 200 according to an embodiment of the present invention.

[0072] The battery cabinet 200 according to an embodiment of the present utility model includes: a support assembly 6.

[0073] Specifically, such as Figure 4 and Figure 5 As shown, the bracket assembly 6 includes the aforementioned support member 100. There are multiple support members 100. The length direction of the first plate 1 is vertical. The multiple support members 100 are arranged in the vertical direction. In two adjacent support members 100, the first plate 1 of the upper support member 100 is attached to the second plate 2 of the lower support member 100, and the first mounting part 11 of the upper support member 100 is connected to the second mounting part 21 of the lower support member 100.

[0074] Along the vertical direction, multiple support members 100 correspond one-to-one with multiple battery packs 7, and each support member 100 is connected to the corresponding battery pack 7, so that multiple battery packs 7 are arranged and fixedly connected along the vertical direction, thereby forming an energy storage system 300.

[0075] Each bracket assembly 6 can be equipped with 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 and other different numbers of support members 100, so that the bracket assembly 6 can fix and connect different numbers of battery packs 7 to meet the power demand of the energy storage system 300.

[0076] This application uses multiple support members 100 connected to form a support assembly 6, which enables the stacking and fixed connection of multiple battery packs 7, thereby forming an energy storage system 300. The support members 100 have a simple structure and uniform specifications, facilitating mass production. Replacing existing cabinets or racks with support members 100 can significantly shorten the processing cycle and reduce production costs. Furthermore, the support members 100 occupy very little space, facilitating transportation and effectively improving the utilization rate of transportation space, thus enhancing transportation efficiency.

[0077] In addition, the multiple support components 100 and the support components 100 and the battery pack 7 can be quickly disassembled, which solves the problem of inconvenience in moving and transporting existing cabinets or racks. It can be applied to usage scenarios where the installation location of the energy storage system 300 needs to be moved frequently, thereby improving the flexibility and applicability of the support components 100 and the energy storage system 300.

[0078] According to the battery cabinet 200 of this utility model embodiment, by connecting the first plate 1 to the battery pack 7, the bracket assembly 6 includes a plurality of support members 100 arranged in a vertical direction. In two adjacent support members 100, the first mounting portion 11 of the upper support member 100 is connected to the second mounting portion 21 of the lower support member 100. The support members 100 can fix and connect the battery pack 7. Through the connection of the first mounting portion 11 and the second mounting portion 21, the plurality of support members 100 can be connected together, thereby facilitating the bracket assembly 6 to fix and connect the plurality of battery packs 7 to form an energy storage system 300. The inclined plate 3 facilitates the alignment of the first plates 1 of the plurality of support members 100, making it convenient for the support members 100 to connect with the battery pack 7. The support member 100 has a simple structure, which can significantly shorten the processing cycle and reduce production costs. Furthermore, the support member 100 occupies very little space, making it convenient for transportation and effectively improving the utilization rate of transportation space, thereby improving transportation efficiency. It is suitable for application scenarios where the installation position of the energy storage system 300 needs to be frequently moved.

[0079] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, multiple support assemblies 6 are spaced apart in a horizontal plane, and these multiple support assemblies 6 are adapted to be arranged around the circumferential direction of the battery pack 7. Thus, each battery pack 7 is connected to multiple support members 100 in the circumferential direction. Along the vertical direction, multiple support members 100 of the same height can jointly support and hold the same battery pack 7. The multiple support assemblies 6 jointly support and connect multiple battery packs 7, thereby improving the stability of the battery cabinet 200 in fixing the battery pack 7, and thus improving the stability and reliability of the energy storage system 300.

[0080] In one specific embodiment, such as Figure 4 As shown, multiple spaced bracket assemblies 6 are connected to opposite sides of the battery pack 7. Specifically, each side of the battery pack 7 can be connected to a different number of bracket assemblies 6, such as 1, 2, 3, 4, or 5.

[0081] In the specific assembly process of the energy storage system 300, multiple support components 100 can be connected and assembled into a bracket assembly 6 first, and then the battery packs 7 can be fixed to the corresponding support components 100 to form the energy storage system 300. Alternatively, multiple support components 100 can be fixed to the battery packs 7 first, and then multiple battery packs 7 can be stacked and fixed layer by layer from bottom to top through the support components 100 to form the energy storage system 300.

[0082] The following describes an energy storage system 300 according to an embodiment of the present invention.

[0083] The energy storage system 300 according to an embodiment of the present invention includes: the battery cabinet 200 and the battery pack 7 described above.

[0084] According to the energy storage system 300 of this utility model embodiment, by connecting the first plate 1 to the battery pack 7, the support assembly 6 includes a plurality of support members 100 arranged in a vertical direction. In two adjacent support members 100, the first mounting portion 11 of the upper support member 100 is connected to the second mounting portion 21 of the lower support member 100. The support members 100 can fix and connect the battery pack 7. Through the connection of the first mounting portion 11 and the second mounting portion 21, the plurality of support members 100 can be connected together, thereby facilitating the support assembly 6 to fix and connect the plurality of battery packs 7 to form the energy storage system 300. The inclined plate 3 facilitates the alignment of the first plates 1 of the plurality of support members 100, thereby facilitating the connection between the support members 100 and the battery pack 7. The support members 100 have a simple structure, which can significantly shorten the processing cycle and reduce production costs. Furthermore, the support members 100 occupy very little space, making them convenient for transportation and effectively improving the utilization rate of transportation space, thereby improving transportation efficiency. This makes them suitable for application scenarios where the installation position of the energy storage system 300 needs to be frequently moved.
