Abstract

La présente invention se rapporte à un nouvel ensemble de batterie (1) et à un nouveau couvercle de module (1.1). Selon la présente invention, la carte de circuit imprimé de surveillance de cellule (1.2) est rentrée et retenue dans un ensemble (1) de cellules de poche au lithium-ion de la manière la plus efficace dans l'espace. Le codage des baies de barre omnibus (1.4) et des fentes de cassette (1.5) donne une conception antierreur. La carte de circuit imprimé (1.2) peut directement être équipée de capteurs de température (2.1). Le couvercle de module (1.1) qui recouvre le dispositif de batterie (4.2) protège les languettes de cellule et les barres omnibus et sert à assurer une cohésion mécanique avec la carte de circuit imprimé (1.2). L'invention comprend en outre des ailettes de protection contre les courts-circuits (1.3) qui offrent également un support mécanique à la carte de circuit imprimé (1.2) pendant l'assemblage. Le matériau du couvercle de module (1.1) est en outre composé d'un matériau non électroconducteur mais thermoconducteur et fait office de dissipateur thermique pour la chaleur produite par les barres omnibus.
