Abstract: front page image
(EN)The present invention relates to a system and method for protecting an inter-battery circuit through which a vehicle lead-storage battery and a lithium polymer battery are connected to each other, wherein a counter-electromotive force generated from the lead-storage battery is prevented from being applied to a MOSFET switch when power is blocked through the MOSFET switch. Therefore, the present invention can prevent a MOSFET switch from over current and prevent electric current, which has leaked from a lead-storage battery when the lead-storage battery is charged, from flowing to a path other than a determined path in advance.
(FR)La présente invention concerne un système et un procédé de protection d'un circuit inter-batterie à travers lequel une batterie de stockage au plomb de véhicule et une batterie au lithium-polymère sont reliées l'une à l'autre. L'application d'une force contre-électromotrice générée à partir de la batterie de stockage au plomb à un commutateur à MOSFET est empêchée lorsque l'énergie est bloquée par l'intermédiaire du commutateur à MOSFET. Par conséquent, la présente invention peut protéger un commutateur à MOSFET contre les surintensités et empêche un courant électrique, qui a fui depuis une batterie de stockage au plomb lorsque la batterie de stockage au plomb est chargée, de s'écouler vers un chemin autre qu'un chemin déterminé à l'avance.
(KO)본 발명은 차량용 납축 배터리 및 리튬 폴리머 배터리가 서로 연결된 회로에 있어서 모스펫(MOSFET) 스위치를 통한 전원 차단 시 납축 배터리로부터 발생되는 역기전력이 모스펫 스위치에 인가되지 않도록 하여 모스펫 스위치를 과전류로부터 방지하고, 또한 납축 배터리의 충전 시 납축 배터리로부터 누출된 전류가 정해진 경로가 아닌 다른 경로로 도통되는 것을 사전에 차단할 수 있는 배터리 간 회로 보호 시스템 및 보호 방법에 관한 것이다.
