[0016] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] In traditional energy storage boxes, steel cable ties are typically used to securely install battery modules composed of battery cells within the box cavity. The bundled battery modules are then hoisted into the box cavity and locked in place. This method requires numerous components and has a complex structure. Furthermore, the steel cable ties and other parts occupy space within the box cavity, reducing the number of battery cells the box can accommodate. In this embodiment, one side wall along the length of the box 1 is designed as a detachable movable side plate 12. A first foam 13 is provided at its compression end 121 and on the corresponding inner wall of the box 1. When the movable side plate 12 is in place, it can compress the battery module 2, thus restricting the battery module 2 along the length of the box 1. Simultaneously, a second foam 15 is provided on one inner wall along the width of the box 1. By inserting a first insulating plate 14 into the other inner wall along the width of the box 1, the battery module 2 can be compressed, thus restricting the battery module 2 along the width of the box 1.

[0018] Please refer to Figures 1 to 4 As shown, this utility model discloses an energy storage box, including a box body 1 for loading at least one set of battery modules 2. The top of the box body 1 is provided with an opening 11. At least one side wall of the box body 1 along its own length direction is a movable side plate 12 detachably mounted on the box body 1. The movable side plate 12 has a pressing end 121 extending into the inner cavity of the box body 1. The inner wall of the box body 1 along its own length direction and the pressing end 121 are provided with a first foam 13 that abuts against the battery module 2. The two inner walls of the box body 1 along its own width direction are respectively provided with a first insulating plate 14 and a second foam 15 that abut against the battery module 2.

[0019] Working principle: During assembly, the battery cells can be inserted one by one into the inner cavity through the opening 11 at the top of the housing 1 and assembled into a battery module 2. By designing one side wall of the housing 1 along its length as a detachable movable side plate 12, and setting a first foam 13 on its extrusion end 121 and the corresponding inner wall of the housing 1, when the movable side plate 12 is installed in place, the battery module 2 can be squeezed to compress the first foam 13, thereby restricting the battery module 2 along the length of the housing 1. At the same time, a second foam 15 is set on one inner wall along the width of the housing 1. By inserting a first insulating plate 14 into the other inner wall along the width of the housing 1, the battery module 2 can be squeezed to compress the second foam 15, thereby restricting the battery module 2 along the width of the housing 1.

[0020] It is worth noting that one side wall of the housing 1 in the width direction can be designed as a detachable movable side plate 12. When the movable side plate 12 is installed in place, the battery module 2 can be squeezed to compress the first foam 13, thereby restricting the battery module 2 in the width direction of the housing 1. A second foam 15 is provided on one inner wall in the length direction of the housing 1. By inserting the first insulating plate 14 into the other inner wall in the length direction of the housing 1, the battery module 2 can be squeezed to compress the second foam 15, thereby restricting the battery module 2 in the length direction of the housing 1.

[0021] The enclosure 1 is preferably made of aluminum alloy, which can reduce the weight of the enclosure 1 while ensuring its strength.

[0022] In some implementations, please refer to Figure 5 As shown, if multiple battery modules 2 are loaded inside the housing 1, a second insulating plate 5 is provided between adjacent battery modules 2. The second insulating plate 5 acts as a physical barrier to effectively block the spread of heat and flame in case the cells 21 of one of the battery modules 2 malfunction.

[0023] In some implementations, please refer to Figure 6 As shown, the housing 1 includes two movable side panels 12 along its length and two symmetrically arranged L-shaped frames 8. The two symmetrical L-shaped frames 8 form part of the housing 1 primarily to reduce the volume of the extrusion die, thereby increasing the extrusion success rate and reducing die and production costs. The two symmetrically arranged L-shaped frames 8 are connected by friction welding.

[0024] In some implementations, please refer to Figure 3 As shown, the battery module 2 includes multiple battery cells 21 arranged along the length or width of the housing 1, and a third foam 22 disposed between two adjacent battery cells 21. During normal battery cell cycling, the third foam 22 absorbs and releases the expansion stress generated by the battery cells 21, maintaining the structural stability of the battery module 2. Simultaneously, in the event of thermal runaway of adjacent battery cells 21, the third foam 22 acts as a physical barrier, effectively preventing the spread of heat and flame.

[0025] In some implementations, please refer to Figure 1 As shown, the top of the battery module 2 is provided with an integrated busbar 3, which is used to electrically connect each of the battery cells 21. The integrated busbar 3 can be used to electrically connect the battery cells 21 carried in the inner cavity of the housing 1 together.

[0026] In some implementations, please refer to Figure 1 and Figure 7As shown, an energy storage box also includes an electrical module 4. A socket 16, electrically connected to the integrated busbar 3, is provided on the outer wall of the box body 1. The electrical module 4 is detachably mounted on the outer wall of the box body 1 and electrically connected to the socket 16. Mounting the electrical module 4 on the outer wall of the box body 1 saves internal space, allowing the box body 1 to accommodate a larger number of battery cells 21. Furthermore, since the electrical module 4 is the most vulnerable part of the entire energy storage box, its external mounting eliminates the need for work on the box body 1, allowing for maintenance of the electrical module 4.

[0027] In some implementations, please refer to Figures 2 to 5 As shown, the bottom of the housing 1 is provided with heat dissipation fins 17. The heat generated by the battery cell 21 during operation is transferred to the housing 1, and the housing 1 uses the heat dissipation fins 17 to improve the heat dissipation effect.

[0028] In some embodiments, a thermally conductive adhesive layer is provided at the bottom of the inner cavity of the housing 1. The thermally conductive adhesive layer not only better transfers the heat generated by the operation of the battery cell 21 to the housing 1, but also, after the thermally conductive adhesive solidifies, it can restrict the battery module 2 in the height direction of the housing 1.

[0029] In some implementations, please refer to Figures 2 to 5 As shown, the outer side wall of the box 1 is provided with reinforcing ribs 18. The reinforcing ribs 18 can enhance the strength of the box 1.

[0030] In some implementations, please refer to Figure 1 and Figure 7 As shown, an energy storage box also includes a cover 6, which covers the opening 11 of the box body 1. After the battery module 2 is assembled inside the box body 1, the cover 6 covers the opening 11 of the box body 1 to protect the battery module 2.

[0031] In some implementations, please refer to Figure 1 As shown, a sealing gasket 7 is provided between the box cover 6 and the box body 1. The sealing gasket 7 is used to seal the opening 11 of the box body 1 to prevent water, dust and other debris from entering the inner cavity of the box body 1 from the opening 11.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
