Abstract

Accumulateur électrochimique muni d'un capteur de détection d'un signal acoustique. L’invention concerne un accumulateur électrochimique (1) comprenant : au moins une cellule électrochimique (2) et un dispositif d'interruption de courant (CID) (4) de la cellule (2) destiné à être activé par une augmentation de la pression dans la cellule (2) et à émettre un signal acoustique lors de son activation, et au moins un capteur (5) du signal acoustique, caractérisé en ce que l'accumulateur (1) comprend un guide d'onde acoustique configuré pour assurer la transmission du signal acoustique au capteur (5) par propagation solide, le au moins un capteur (5) étant agencé en continuité mécanique avec le guide d'onde. La présente invention concerne le domaine de la sécurité des batteries. Elle trouve pour application particulièrement avantageuse le domaine des accumulateurs électrochimiques, pouvant être à électrolyte solide ou liquide, notamment au lithium, pour détecter les états de sécurité. La présente invention concerne plus spécifiquement la détection et le traitement de l’information reçue par des capteurs acoustiques. Figure pour l’abrégé : Fig.4Electrochemical accumulator fitted with a sensor for detecting an acoustic signal. The invention relates to an electrochemical accumulator (1) comprising: at least one electrochemical cell (2) and a current interrupting device (CID) (4) of the cell (2) intended to be activated by an increase in pressure in the cell (2) and to emit an acoustic signal when it is activated, and at least one sensor (5) of the acoustic signal, characterized in that the accumulator (1) comprises an acoustic waveguide configured to ensure the transmission of the acoustic signal to the sensor (5) by solid propagation, the at least one sensor (5) being arranged in mechanical continuity with the waveguide. The present invention relates to the field of battery safety. It finds for particularly advantageous application the field of electrochemical accumulators, which can be with solid or liquid electrolyte, in particular with lithium, to detect the states of security. The present invention relates more specifically to the detection and processing of information received by acoustic sensors. Figure for abstract: Fig.4
