Abstract

Module d’accumulateurs apte à la gestion d’une surpression interne L’invention concerne un module d’accumulateurs (1) comprenant un caisson logement (11) à l’intérieur duquel une pluralité de cellules électrochimiques (12) sont juxtaposées et connectés avec une interface de connexion électrique (13), le caisson logement (11) comprenant un caisson (111) et un couvercle (112) complémentaire au caisson (111) et fixé par une liaison étanche sur sa périphérie, caractérisé en ce que le module d’accumulateurs (1) comprend des moyens de gestion d’une surpression dans son volume intérieur comprenant une ligne de faiblesse (21) dans l’épaisseur de l’une des faces (2) du caisson logement (11), cette ligne de faiblesse (21) longeant au moins une partie du bord d’une face (2) du caisson logement (11), de sorte que au moins une portion (22) de la ligne de faiblesse (21) soit fragilisée pour se rompre de façon localisée et circonscrite en cas de surpression à l’intérieur du caisson logement (11) au-delà d’une valeur seuil. Figure à publier avec l’abrégé : Fig. 2
