The utility model provides a battery module which comprises a module body, two end plates and a winding belt, one of the two end plates is arranged on a first end face of the module body, the other one of the two end plates is arranged on a second end face of the module body, and the first end face and the second end face are oppositely arranged; and the winding belt is wound on the outer surfacesof the module body and the two end plates. Therefore, through the matching of the module body, the two end plates and the winding belt, the arrangement of side plates in the battery module can be omitted, the grouping efficiency of the battery module can be improved, and the weight of the battery module can also be reduced, so that the manufacturing cost of the battery module can be reduced, andthe situation of poor welding of the battery module can be avoided.
