Abstract

Système de dégazage configuré pour gérer un possible dégagement de gaz à partir d’une pluralité de cellules électrochimiques (2) de batterie de véhicule électrique, le système de dégazage comprenant un collecteur de rétention (1) délimitant généralement hermétiquement un volume tampon (V1), le collecteur de rétention comprenant en vis-à-vis de chaque cellule une ouverture faisant partie d’un passage à ouverture sélective (PS) entre un volume intérieur de la cellule et le volume tampon (V1), chaque cellule comprenant une première soupape de décharge (3), configurée pour faire communiquer le volume intérieur de la cellule avec le collecteur de rétention en cas de surpression à l’intérieur de la cellule, le système de dégazage comprenant au moins une deuxième soupape de décharge aval (4) agencée sur une paroi du collecteur de rétention, configurée pour faire communiquer le volume tampon avec l’air ambiant en cas de surpression à l’intérieur.
