System and method for detecting venting of a sealed storage cell

A venting detection system for a sealed storage cell, the sealed storage cell comprising a container comprising a sealing cap adapted to be detached from the rest of the container and to move in the presence of excessive gas pressure within the container to allow the venting of said sealed storage cell, the detection system comprising a printed circuit board comprising:

• a central portion delimited by a circumference designed to be situated facing said sealing cap
• a peripheral portion surrounding the central portion and connected to said central portion by connecting means consisting of:
• a hinge adapted to flex during movement of the sealing cap, and
• at least one frangible portion adapted to break upon movement of the sealing cap
• an electrical track connecting said peripheral portion to the central portion through the hinge and at least one frangible portion, the electrical printed track being adapted to be broken through breaking of the frangible portion upon movement of the sealing cap.
