摘要

The system (1) has a compressible compartment (4) including electrochemical cells (2) and a compressible pocket (31) for protection against a shock. The pocket is placed between one of the electrochemical cells and the compartment. The pocket comprises a shock absorber element (6) that is made of a material chosen among gel, gas or foam. The element is fireproofed to delay propagation of a starting point of fire. The pocket is provided with a drilling point adapted to bore a wall of the cell. The point comprises a weakness zone adapted to create an opening in the pocket.
