| Zusammenfassung: | Disclosed are a battery management system having a reverse voltage protection function for multi-battery management and a reverse voltage protection circuit therefor. According to one aspect of the present invention, the battery management system comprises: a BMS semiconductor for managing two battery modules connected by a busbar by using a plurality of channels; and a protection circuit unit that prevents overcurrent from flowing into the BMS semiconductor when a reverse voltage occurs in a voltage applied to the busbar.
멀티 배터리 관리를 위한 역전압 보호 기능을 갖는 배터리관리시스템 및 그를 위한 역전압 보호회로가 개시된다. 본 발명의 일측면에 따른 배터리관리시스템은 버스바(busbar)로 연결되는 두 개의 배터리 모듈을 복수의 채널을 이용하여 관리하기 위한 BMS반도체 및 버스바에 걸리는 전압에 역전압이 발생하면 BMS반도체에 과전류의 유입을 방지하는 보호회로부를 포함한다. |
