BATTERY MODULE COMPRISING AN ENERGY STORING ELEMENT WHEREOF THE CONTACT IS ACTIVATED BY MUTUAL LAYER TIGHTENING

摘要

The invention concerns a battery module comprising at least one element consisting of stacked layers, some layers (40) having edges extending beyond the edges of other layers, thus forming projecting parts (42), and a tightening member (100) maintaining the projecting parts (42) of the layers (40) tightly close together. The invention is characterized in that the tightening member is a self-contained elastic member which by itself, without external aid, provides for the tightening of said projecting parts (42) and its own grip thereon, and is adapted to provide an electrical connection of said layers (40) to a circuit.
