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.
