Battery comprising at least one stack of electrical cells and an associated elastic play recovery device

Abstract

This electrical energy storage battery (1) comprises at least one stack (7) of electrical cells (6) and a casing having a base (3) on which said stack (7) of battery cells (1) is fixed. The battery (1) comprises at least two compression plates (8) arranged on either side of the stack, means for fixing the compression plates (8) to the base (3), at least one tie rod (12) capable of compressing the compression plates (8) against the cells (6) of the stack (7), and at least one elastic device (15) for compensating for play in the stack in a direction of dimensional variation of the stack.
