Abstract
(EN) The present subject matter relates generally to provide a closely packed battery having a plurality of partition structure arranged to separate a plurality of cell units 208. The plurality of partition structure includes a first partition structure 201 and a second partition structure 211 being adapted to prevent flame propagation to the other cell unit of the battery pack 100. The first partition structure 201 is placed between a cell module 202 and the second partition structure 211 is placed on a top and a bottom portion of the closely packed cell module 202 in the battery pack. This configuration prevents the propagation of flame from one cell unit 208 to another cell unit 208 and restricts the flames within the battery pack 100 keeping the vehicle and the rider of the vehicle safe.
(FR) La présente invention concerne, de manière générale, une batterie compacte ayant une pluralité de structures de séparation agencées pour séparer une pluralité d'unités de cellule 208. La pluralité de structures de séparation comprend une première structure de séparation 201 et une seconde structure de séparation 211 conçues pour empêcher la propagation des flammes vers l'autre unité de cellule du bloc-batterie 100. La première structure de séparation 201 est placée entre un module de cellules 202 et la seconde structure de séparation 211 est placée sur une partie supérieure et une partie inférieure du module de cellules 202 compacte dans le bloc-batterie. Cette configuration empêche la propagation des flammes d'une unité de cellule 208 à une autre unité de cellule 208 et limite la propagation des flammes à l'intérieur du bloc-batterie 100 tout en maintenant le véhicule et le conducteur du véhicule en sécurité.
