The present invention relates to a method for conserving an energy when ignition of a fuel cell vehicle is turned off. According to the present invention, when a vehicle is turned off, a residual energy of a high-voltage stage of a motor and a supercapacitor is recovered by a low-voltage battery. Accordingly, energy loss and stack durability degradation are prevented. The method for conserving the energy when the ignition of the fuel cell vehicle is turned off according to the present invention comprises: a computing step; a calculating step; and a charging step.

    본 발명은 연료전지 차량의 시동 오프 시 에너지 보존 방법에 관한 것으로, 차량의 시동 오프 시 모터 고전압단 및 수퍼캐패시터의 잔류에너지를 저전압배터리로 회수하여서 에너지 손실 및 스택 내구 저하를 방지하도록 한 연료전지 차량의 시동 오프 시 에너지 보존 방법을 제공하는 것에 목적이 있다.
