Abstract
The present application relates to an end plate assembly of a battery module and a battery module. The end plate assembly includes an end plate and an energy absorbing component, the energy absorbing component is arranged between the end plate and a battery, the energy absorbing component includes a stress bearing plate and a bending plate, the bending plate and the stress bearing plate are connected with each other. After the battery module is assembled, if the battery of the battery module expands and applies an expansion force to the energy absorbing component, then the bending plate of the energy absorbing component will deform elastically, so as to absorb the expansion force of the battery. Therefore, the end plate of the end plate assembly will stress smaller expansion force, so as to prevent the battery module from failure, thereby improving structural strength of the battery module.
