According to the present invention, provided is a failure diagnosing device of a precharge device, which is configured to sense a current flowing through a precharge resistor by a precharge relay and a current sensor connected in series with the precharge resistor. Since a control unit is configured to diagnose a failure of a precharge device using the current sensed by the current sensor, so that it is possible to diagnose both the failure of the precharge resistor and the precharge relay constituting the precharge device.

    본 발명에 따른 프리차지 장치의 고장 진단 장치는 프리차지 릴레이 및 프리차지 저항과 직렬로 연결되는 전류 센서에 의해 프리차지 저항에 흐르는 전류를 센싱하고, 제어부가 상기 전류 센서에 의해 센싱되는 전류를 이용하여 프리차지 장치의 고장을 진단하도록 구성되어 있기 때문에, 프리차지 장치를 구성하는 프리차지 저항 및 프리차지 릴레이의 고장을 모두 진단할 수 있게 된다.
