The battery module includes a battery module body, two end plates and a plurality of fixing belts; the end plates are arranged at both ends of the length direction of the battery module body; the fixing belt is sleeved outside the two end plates, and the two end plates clamp the battery module body; and the plurality of fixing belts pass through the upper and lower parts of the battery module body, and the battery module relies on the fixing belt to clamp the two end plates to the battery module body, and the fixing belt is located below the battery module body, which can play a role in supporting the battery module body; compared with the existing battery module, the bottom plate of the battery module is reduced, the mass of the entire battery module is reduced, and the energy density of the battery module is improved, but the patent still has the following problems in actual use:

[0004] The device achieves the effect of splicing and fixing the battery cells by providing a first connecting plate and a fixing belt. However, when assembling the battery cells, it is difficult to quickly limit the positions of the upper and lower ends of the battery cells by the fixing belt, resulting in poor stability in the vertical direction of the battery cells after being fixed by the fixing belt. The battery cells that are tightly attached after being fixed are not conducive to the heat dissipation of the battery module, and the battery module does not protect the upper and lower ends of the battery cells, resulting in poor safety of the battery module. When the battery module is in use, the electric row of the battery module is exposed to the outside of the battery module, which easily affects the overall aesthetics of the battery module and is not convenient for disassembly of the battery module, resulting in poor practicality of the battery module.
