Title
(EN) BATTERY MODULE USING POUCH CELLS
(FR) MODULE DE BATTERIE UTILISANT DES CELLULES DE POCHE
Abstract
(EN)
A battery module made from a plurality of side-by-side pouch cell modules, wherein each pouch cell module is formed with a pair of cells on either side of an insulation pad with the cells in turn positioned between first and second metal brackets such that each cell contacts an insulation pad on one side and a metal bracket on the other. Also included are a pair of pressure plates at the ends of the stack of side-by-side pouch cells and a compression band wrapping around the plurality of side-by-side pouch cells and the pressure plates. A busbar electrically connects the plurality of side-by-side pouch cells together.
(FR)
La présente invention concerne un module de batterie constitué d'une pluralité de modules de cellules de poche côte à côte, chaque module de cellule de poche étant formé d'une paire de cellules de chaque côté d'une pièce d'isolation, les cellules étant à leur tour positionnées entre des premier et second supports métalliques de telle sorte que chaque cellule entre en contact avec une pièce d'isolation sur un côté et un support métallique sur l'autre côté. La présente invention concerne également une paire de plaques de pression au niveau des extrémités de la pile de cellules de poche côte à côte et une bande de compression enveloppant la pluralité de cellules de poche côte à côte et les plaques de pression. Une barre omnibus raccorde électriquement ensemble la pluralité de cellules de poche côte à côte.
