Title
(EN) BATTERY CELL FOR ELECTRIC VEHICLE BATTERY PACK
(FR) ÉLÉMENT DE BATTERIE POUR BLOC-BATTERIE DE VÉHICULE ÉLECTRIQUE
Abstract
(EN)
Provided herein is a battery cell of a battery pack to power an electric vehicle. The battery cell can include a housing having a first end and a second end and defining an inner region. The battery cell can include a lid that includes a first polarity portion, a second polarity portion and a first isolation layer between the first polarity portion and the second polarity portion. The second polarity portion can be coupled with the first end of the housing. The battery cell can include an electrolyte disposed in the inner region defined by the housing and a first polarity tab that electrically couples the electrolyte with the first polarity portion of the lid. The first polarity tab can include a spring element. The spring element can be configured to apply a force at a predetermined level to the electrolyte.

L'invention concerne un élément de batterie d'un bloc-batterie destiné à alimenter un véhicule électrique. L'élément de batterie peut comprendre un boîtier ayant une première extrémité et une seconde extrémité et définissant une région interne. L'élément de batterie peut comprendre un couvercle qui comprend une première partie de polarité, une seconde partie de polarité et une première couche d'isolation entre la première partie de polarité et la seconde partie de polarité. La seconde partie de polarité peut être couplée à la première extrémité du boîtier. L'élément de batterie peut comprendre un électrolyte disposé dans la région interne définie par le boîtier et une première languette de polarité qui couple électriquement l'électrolyte à la première partie de polarité du couvercle. La première languette à polarité peut comprendre un élément ressort. L'élément ressort peut être configuré pour appliquer une force à un niveau prédéterminé à l'électrolyte.
