Abstract

L'invention porte sur un système de refroidissement de batterie qui permet de supprimer des élévations de température d'une batterie durant des opérations en stationnement, et permet d'allonger la durée de vie de la batterie. Le système de refroidissement de batterie comprend un boîtier (2) qui contient une batterie (3) qui est chargée et déchargée, une partie de stockage de refroidissement (6) destinée à un stockage thermique et qui est formée d'une seule pièce avec le boîtier (2) sur l'intérieur de la surface de paroi de celui-ci, et un ventilateur de refroidissement (4) et une partie de passage de refroidissement (5) pour refroidir la partie de stockage de refroidissement (6). Des moyens de refroidissement comportent le ventilateur de refroidissement (4) permettant d'envoyer de l'air de refroidissement vers la batterie (3) et la partie de passage de refroidissement (5) pour distribuer une partie de l'air retenue pour la batterie (3) vers la partie de stockage de refroidissement (6).
