Battery module

A battery module, comprising a plurality of batteries, a first enclosing plate, a second enclosing plate, and fasteners, wherein

• the first enclosing plate comprises a first side plate, a first front plate connected to the first side plate and containing a first connecting hole, and a first rear plate connected to the first side plate and containing a third connecting hole, wherein the first rear plate and the first front plate are disposed oppositely in a longitudinal direction;
• the second enclosing plate comprises a second side plate, a second front plate connected to the second side plate and containing a second connecting hole, and a second rear plate connected to the second side plate and containing a fourth connecting hole, wherein the second rear plate and the second front plate are disposed oppositely in the longitudinal direction;
• the battery module further comprises two end plates disposed on two sides of the plurality of batteries along the longitudinal direction;
• the first front plate and the second front plate are at least partially stacked, and the first connecting hole and the second connecting hole are penetrated through and overlapped along a stacked direction of the first front plate and the second front plate;
• the first rear plate and the second rear plate are at least partially stacked, and the third connecting hole and the fourth connecting hole are penetrated through and overlapped along a stacked direction of the first rear plate and the second rear plate;
• and
• the first front plate and the second front plate are fixedly connected to one of the two end plates by the fasteners penetrating through the first connecting hole and the second connecting hole, and the first rear plate and the second rear plate are fixedly connected to the other of the two end plates by the fasteners penetrating through the third connecting hole and the fourth connecting hole, so that the first enclosing plate, the second enclosing plate and the two end plates jointly enclose and fix the plurality of batteries.
