실시 예의 릴레이 융착 진단 방법은 스택 전압을 제공하는 연료 전지와, 충전 전압 또는 스택 전압의 레벨을 증가시켜 승압 전압으로서 출력하는 멀티 컨버터와, 충전기와 멀티 컨버터 사이에 배치된 충전 릴레이 및 승압 전압의 전기 에너지를 저장하는 배터리를 포함하고, 멀티 컨버터는 충전 릴레이와 배터리 사이에 연결되어, 승압 전압을 생성하는 승압부 및 충전 릴레이의 입력단 전압과 출력단 전압을 센싱한 결과를 이용하여, 충전 릴레이의 융착 여부를 진단하는 컨버터 제어부를 포함한다.

    A vehicle including a relay welding diagnosis function and a relay welding diagnosis method performed in the vehicle, is configured to be connectable to a charger providing a charging voltage, and includes a fuel cell configured to provide a stack voltage, a multi-converter configured to increase the level of the charging voltage or the stack voltage and to output the charging voltage or the stack voltage having the increased level as a boosted voltage, a charging relay disposed between the charger and the multi-converter, and a battery configured to store electrical energy of the boosted voltage. The multi-converter includes a voltage booster connected between the charging relay and the battery and configured to generate the boosted voltage and a converter controller configured to diagnose whether the charging relay is welded using a result of sensing an input-terminal voltage and an output-terminal voltage of the charging relay.
