최소셀전압비율에 도달할 경우, 해당 시점의 연료전지 출력전류를 사전제한전류로 저장하는 단계; 셀전압비율이 위험셀전압비율에 도달할 경우 연료전지의 출력제한전류를 사전제한전류로 설정하는 단계; 셀전압비율이 위험셀전압비율에 도달할 경우 제1고전압배터리와 제2고전압배터리가 병렬로 메인버스단에 연결되도록 하는 단계; 및 연료전지 출력전류가 사전제한전류에 모자란 만큼 제2고전압배터리로부터 보충전류를 출력하는 단계;를 포함하는 연료전지 차량의 에너지 공급 제어방법 및 제어시스템이 소개된다.

    A method of controlling energy supply in a fuel cell vehicle includes storing an output current of a fuel cell as a pre-limited current when a cell voltage ratio reaches a minimum cell voltage ratio, setting a limited output current of the fuel cell as the pre-limited current when the cell voltage ratio reaches a hazard cell voltage ratio, connecting first and second high-voltage batteries to a main bus terminal in parallel when the cell voltage ratio reaches the hazard cell voltage ratio, and outputting a supplementary current from the second high-voltage battery by an insufficient amount of the output current of the fuel cell for the pre-limited current, and a system for performing the same.
