Abstract

Le problème à résoudre dans le cadre de cette invention consiste à loger un grand nombre d'éléments de batterie secondaire sans augmenter le coût. La solution consiste en un support d'éléments (20) qui est divisé dans le sens de la longueur des unités de logement d'éléments, en un premier support divisé (21), un deuxième support divisé (22) et un troisième support divisé (23). Les premier support divisé (21), deuxième support divisé (22) et troisième support divisé (23) sont formés par moulage par injection. Le premier support divisé (21) est fixé à la surface interne d'un premier boîtier divisé (12A), le deuxième support divisé (22) est fixé à la surface interne d'un second boîtier divisé (12B) et le troisième support divisé (23) est intercalé entre le premier support divisé (21) et le deuxième support divisé (22). Les premier support divisé (21), troisième support divisé (23) et deuxième support divisé (22) sont combinés pour former une pluralité d'unités de logement d'éléments permettant de loger les éléments de batterie secondaire (11).
