The present invention relates to a relay reconnection method in a battery management system. The inside and outside of a battery system are distinguished when a high voltage relay is stopped by the generation of insulating resistance failure. It is determined whether a high voltage relay connection is carried out again. So, unnecessary relay reconnection is minimized. Anxiety about repeat reconnections is removed. The relay reconnection method informs a user that the operation of the failure part of a high voltage such as a motor, an air compressor must be stopped. So, the normal driving of a vehicle can be carried out.

    본 발명은 절연 저항 고장의 발생에 따른 고전압 릴레이 차단 시에 배터리 시스템 내외부를 구분하여 고전압 릴레이 재접속 여부를 결정하여 불필요한 릴레이 재접속을 최소화함으로써 재접속이 반복되면서 발생할 수 있는 불안감을 제거하고, 모터, 에어컨 콤프레셔 등 고전압 장치에서의 고장 부위 동작 금지를 경보하여 차량의 정상 주행이 가능하도록 할 수 있는, 차량 배터리 관리 시스템의 릴레이 재접속 방법에 관한 것이다.
