Abstract
(EN)
The present invention relates to a device and a method for preventing the overcharge of a rechargeable battery, whereby overcharge is prevented for a starting lighting ignition (SLI) battery having at least one rechargeable battery. The device for preventing overcharge, according to one embodiment of the present invention, regulates a voltage applied to a cell assembly, and thus has an advantage of being applicable to both a system which has a voltage regulator (a regulated system) and a system which does not have a voltage regulator (an unregulated system).
(FR)
La présente invention concerne un dispositif et un procédé de prévention de surcharge d'une batterie rechargeable, moyennant quoi une surcharge d'une batterie de démarrage, d'éclairage et d'allumage (SLI) comportant au moins une batterie rechargeable est empêchée. Le dispositif de prévention de surcharge, selon un mode de réalisation de la présente invention, régule une tension appliquée à un ensemble d'éléments, et présente ainsi l'avantage de pouvoir être appliqué à la fois à un système qui comporte un régulateur de tension (un système régulé) et à un système qui ne comporte pas de régulateur de tension (un système non régulé).
(KO)
본 발명은 적어도 하나 이상의 이차 전지를 구비하는 SLI(Starting Lighting Ignition) 배터리의 과충전을 방지하는 이차 전지의 과충전 방지 장치 및 방법에 관한 것이다. 본 발명의 일 실시예에 따른 과충전 방지 장치는, 셀 어셈블리에 인가되는 전압을 조정하여, 전압 조정기가 구비된 시스템(Regulated System)과 전압 조정기가 구비되지 않은 시스템(Unregulated System)에 모두 적용될 수 있는 장점이 있다.
