Abstract
(EN)
A battery pack (10) having a substantially sealed structure comprises a plurality of cells (11-16), each provided with an open part through which gas is discharged when there is an increase in internal pressure. A non-resettable pressure switch unit (30, 31) is connected to a controller (50) via a signal line, and irreversibly changes from a significant state to an insignificant state when the pressure within the battery pack (10) exceeds a prescribed pressure threshold.
(FR)
Un bloc-batterie (10) ayant une structure sensiblement étanche comprend une pluralité de cellules (11-16), chacune pourvue d'une partie ouverte à travers laquelle un gaz est évacué lorsqu'il y a une augmentation de la pression interne. Une unité de commutation de pression non réinitialisable (30, 31) est connectée à un dispositif de commande (50) par l'intermédiaire d'une ligne de signal, et passe de manière irréversible d'un état significatif à un état négligeable lorsque la pression à l'intérieur du bloc-batterie (10) dépasse un seuil de pression prescrit.

略密閉構造の電池パック(10)に、内圧が上昇した場合に内部のガスを排出するための開放部がそれぞれ設けられている複数のセル(11-16)が含まれている。非復帰型の圧力スイッチ部(30、31)は、コントローラ(50)に信号線で接続され、電池パック(10)内の圧力が所定の圧力閾値を上回った場合、有意な状態から非有意な状態に不可逆的に変化する。
