Le bloc-batterie comprend un contrepoids et au moins une cellule de batterie comprenant une partie réunie au contrepoids. Le bloc-batterie est installé sur la caisse de véhicule de telle sorte qu'une partie de la cellule de batterie qui n'est pas réunie au contrepoids échange de la chaleur avec un vent de déplacement davantage que la partie de la cellule de batterie réunie au contrepoids.
