Title (EN) OFF-PREVENTION CIRCUIT OF CONTACTOR
(FR) CIRCUIT DE PRÉVENTION DE DÉSACTIVATION D'UN CONTACTEUR
(KO) 컨택터의 오프 방지 회로
Abstract:
(EN) The present invention relates to an off-prevention circuit of a contactor, wherein the off-prevention circuit makes multiple connections between a battery management system and the contactor through a plurality of positive/negative terminals provided in the battery management system and the contactor, so that, even when one connection among connections between the multiple positive/negative terminals is short-circuited or opened, the off-prevention circuit can maintain power supplied to the contactor from the battery management system through another connection between the multiple positive/negative terminals.
(FR) La présente invention concerne un circuit de prévention de désactivation d'un contacteur. Le circuit de prévention de désactivation effectue de multiples connexions entre un système de gestion de batterie et le contacteur par l'intermédiaire d'une pluralité de bornes positives/négatives disposées dans le système de gestion de batterie et le contacteur, de telle sorte que, même lorsqu'une connexion parmi des connexions entre les multiples bornes positives/négatives est court-circuitée ou ouverte, le circuit de prévention de désactivation peut maintenir la puissance fournie au contacteur par le système de gestion de batterie par l'intermédiaire d'une autre connexion entre les multiples bornes positives/négatives.
(KO) 본 발명은 배터리 관리 시스템과 컨택터를 각각에 구비되는 복수의 양/음극 단자를 통해 다중으로 연결시킴으로써, 복수의 양/음극 단자 간의 연결 중 어느 하나의 연결이 단락 또는 개방되더라도, 다른 하나의 양/음극 단자의 연결을 통해 배터리 관리 시스템으로부터 컨택터에 공급되는 전원 공급을 유지할 수 있는 컨택터의 오프 방지 회로에 관한 것이다.
