본 개시는 배터리 팩 보호장치 및 그 방법에 관한 것으로, 해결하고자 하는 기술적 과제는 자동차 시동 시 배터리 팩 및 릴레이의 고장에 대응하여 자동차를 안정적으로 시동 오프 할 수 있고, 안전사고로부터 탑승자와 자동차를 보호하는 배터리 팩 보호장치 및 그 방법을 제공하는 데 있다. 이를 위해 본 개시는 배터리 모듈, 상기 배터리 모듈의 출력이 자동차의 부하로 인가되도록 하거나 차단하는 릴레이, 시동배터리로부터 공급되는 전원에 의해 동작하는 액추에이터 및 시동신호가 입력되면 상기 배터리 모듈을 모니터링하고 상기 릴레이의 고장을 검출하며, 상기 릴레이가 고장인 경우 상기 액추에이터를 동작하도록 제어하여 상기 시동배터리의 방전에 의해 상기 자동차의 시동을 차단하는 프로세서를 포함한다.

    The present disclosure relates to an apparatus and method for protecting a battery pack, and the technical object to be achieved is to provide an apparatus and method for protecting a battery pack in which, when a vehicle is started, the ignition of the vehicle may be stably turned off in response to a failure of a battery pack and a relay, and passengers and the vehicle may be protected from accidents. To this end, the apparatus of the present disclosure includes a battery module, a relay configured to allow an output of the battery module to be applied as a load of a vehicle or block the output of the battery module, an actuator operated by power supplied from a starter battery, and a processor configured to, when a start signal is input, monitor the battery module and detect a failure of the relay, and when the relay fails, control the actuator to operate to discharge the starter battery and block a start of the vehicle.
