Title (EN) BATTERY PACK INCLUDING CELL RESTRAINT
(FR) BLOC-BATTERIE COMPRENANT UN DISPOSITIF DE RETENUE DE CELLULE
Abstract:
(EN) A battery pack (1) includes a housing (2) and an array (40) of electrochemical cells (80) disposed in the housing (2). The housing (2) includes a container (3) and a lid (30) that closes an open end of the container (3). The container (3) has a base (4), a sidewall (8) that surrounds the base (4), and a spring plate (110) disposed inside the sidewall (8) between the cells (80) and the sidewall (8). The spring plate (110) is free standing within the container (3) and applies a spring force to the cell array (40) that restrains the cells (80) along an axis normal to the surface of the spring plates (110). The lid (30) includes inwardly-protruding pins (50, 60) that further restrain the cells (80) within the housing (2).
(FR) L'invention concerne un bloc-batterie (1) comprenant un boîtier (2) et un réseau (40) de cellules électrochimiques (80) disposées dans le boîtier (2). Le boîtier (2) comprend un récipient (3) et un couvercle (30) renfermant une extrémité ouverte du récipient (3). Le récipient (3) a une base (4), une paroi latérale (8) qui entoure la base (4), et une plaque à ressort (110) disposée à l'intérieur de la paroi latérale (8) entre les cellules (80) et la paroi latérale (8). La plaque à ressort (110) est libre à l'intérieur du récipient (3) et applique une force de ressort au réseau de cellules (40) qui restreint les cellules (80) le long d'un axe perpendiculaire à la surface des plaques à ressort (110). Le couvercle (30) comprend des broches faisant saillie vers l'intérieur (50, 60) qui restreignent en outre les cellules (80) à l'intérieur du boîtier (2).
