Abstract

Ce système de refroidissement d’une batterie de traction d’un véhicule automobile comporte une prise de charge (12), une batterie de traction comportant au moins un connecteur de puissance fixé sur une surface et au moins un câble électrique connectant la prise de charge au connecteur de puissance. Il comporte en outre une première pluralité d’alvéoles (20) disposées autour de la prise de charge (12) ; un conduit disposé autour du câble électrique et en communication de fluide avec la première pluralité d’alvéoles (20) ; une seconde pluralité d’alvéoles disposées dans la surface précitée, autour du connecteur de puissance et en communication de fluide avec le conduit. Les première et seconde pluralités d’alvéoles et le conduit sont destinés à recevoir un fluide de refroidissement en cas d’emballement thermique de la batterie de traction. Figure pour l’abrégé : Fig. 2
