Abstract

La présente invention concerne un module de batterie comprenant de multiples rangées de batteries comprenant de multiples cellules de batterie. Chacune des cellules de batterie comprend un boîtier de batterie incliné ayant une surface inférieure, une première paire de surfaces latérales de grande largeur, et une seconde paire de surfaces latérales de petite largeur. Le module de batterie comprend en outre de multiples premières barres omnibus et au moins une seconde barre omnibus. Les première et seconde barres omnibus sont conçues pour connecter électriquement les cellules de batterie. Selon la présente invention, les cellules de batterie adjacentes dans la même rangée se font face par leurs surfaces latérales de petite largeur, et les cellules de batterie adjacentes dans des rangées adjacentes se font face par leurs surfaces latérales de grande largeur. De plus, les cellules de batterie adjacentes dans la même rangée sont connectées électriquement en série par l'intermédiaire de l'une des multiples premières barres, et les rangées individuelles sont connectées électriquement en série par l'intermédiaire d'au moins une seconde barre omnibus. Par conséquent, les chemins de rangée à travers les boîtiers de batterie et les barres omnibus, en tant que connecteurs électriques, sont séparés, et le risque de propagation d'un emballement thermique dans le module de batterie est réduit.
