Abstract: The present disclosure provides a battery module. The battery module includes a plurality of batteries that are stacked and two end plates disposed at two ends of the plurality of batteries in a stacking direction of the batteries. The battery module further includes a fixing strap, which includes a strap-shaped body and an elastic fixing part. The strap-shaped body surrounds the plurality of batteries and the end plates and defines a gap. The elastic fixing part is disposed in the gap and connected to the strap-shaped body. The elastic fixing part, together with the strap-shaped body, can provide an expansion space for the battery module with a certain restraint. In this way, the deformation of the battery module can be suppressed, and the battery module is protected from being damaged by a shear force of the strap-shaped body, thereby improving reliability of the battery performance.

Abstract: The present application relates to the technical field of batteries and, particularly, relates to an end plate of a battery module and a battery module. The end plate of a battery module includes a main body and an energy absorbing body, the energy absorbing body includes an acting portion and a connecting portion, the acting portion protrudes in a direction from the main body toward a battery, and the acting portion is connected with the main body through the connecting portion. After the battery module is assembled, if the battery of the battery module expands and applies an expansion force to the end plate, then the energy absorbing body will deform elastically, so as to absorb the expansion force of the battery. Therefore, the end plate can prevent the housing of the battery module from failure, so as to improve structural strength of the battery module.
