본원발명에 따른 자동차 전원 릴레이 오프 점검 시스템 및 이를 이용한 양극 릴레이 및 음극 릴레이의 오프 여부를 확인하는 방법은 이차전지 팩을 구비한 전기자동차에 있어서, 자동차의 운전이 중지되었을 때 능동 방전회로를 작동시켜 자동차 캐패시터를 방전시킴으로써 상기 이차전지 팩과 전기자동차 사이에 마련된 릴레이의 온/오프를 신속하게 파악할 수 있는 장점이 있다. 또한 본원발명은 자동차가 운전이 완전히 중지되었음에도 불구하고 릴레이가 오프가 되지 않았을 경우로 확인될 경우, 사용자에게 알람을 보내고 강제적으로 해당 자동차의 시동이 걸리지 않게 하여 추가의 위험을 예방할 수 있는 효과가 있다.

    The present invention relates to a vehicle power relay short circuit checking system and a method for checking short circuit of positive electrode relay and a negative electrode relay using the same are able to, in an electric vehicle having a secondary battery pack, when the driving of the vehicle is stopped, operate an active discharge circuit, discharge a vehicle capacitor, and rapidly identify whether the relay placed between the secondary battery pack and the electric vehicle is on or off. In addition, the present invention is able to, when it is found that the relay has not been short-circuited even if the driving of the vehicle has stopped completely, send an alarm to a user, forcibly prevent the vehicle from being started, and prevent any additional danger.
