제어부에서, 연료전지에 수소와 공기를 공급하여, 상기 연료전지의 출력단이 연결된 고전압버스단과 고전압 배터리 사이에 마련된 컨버터의 상기 고전압 버스단 측 전압이 사전 설정된 최저 제어전압이 되도록 정전압 제어하는 단계; 상기 제어부에서, 상기 고전압 배터리의 목표충전전류를 충전제한전류로 설정하는 단계; 상기 제어부에서, 상기 공기의 공급량 및 상기 컨버터를 제어하여 상기 충전제한전류의 크기에 대응되는 전류를 상기 고전압 배터리로 제공하는 단계; 및 상기 제어부에서, 상기 고전압 배터리로 입력되는 전류를 센싱한 센싱충전전류와 상기 충전제한전류를 비교한 결과에 기반하여 상기 충전제한전류를 변경하는 단계를 포함하는 연료전지 차량의 시동 제어방법이 개시된다.

    A system and method for controlling a start of a fuel cell vehicle are provided. The method includes providing hydrogen and air to a fuel cell and operating a converter to maintain a voltage of a high voltage bus constant. The converter is disposed between a high-voltage battery and the high voltage bus to which an output stage of the fuel cell is connected, and the voltage of the high voltage bus becomes a preset lowest control voltage. A charge current of the high-voltage battery is set as a charge limit current and an air supply amount is adjusted and the converter is operated to provide a current corresponding to an amplitude of the charge limit current to the high-voltage battery. The charge limit current is changed based on comparing a sensed charge current, obtained by sensing a current input to the high-voltage battery, with the charge limit current.
