연료전지; 연료전지와 메인버스단을 통하여 연결된 고전압배터리; 고전압배터리의 충방전을 제어하는 충방전부; 메인버스단에서 분기되어 차량 외부의 부하와 연결되어 연료전지 또는 고전압배터리의 전력을 차량 외부의 부하에 공급하는 전력공급라인; 및 차량 외부의 부하에 공급하는 전력의 크기 및 고전압배터리의 충전량(SOC)을 함께 고려하여 연료전지의 가동 및 충방전부를 제어하는 제어부;를 포함하는 연료전지 차량의 외부 전력 공급시스템이 소개된다.
An external power supply system of a fuel cell vehicle is provided. The system includes a fuel cell and a high voltage battery that is connected to the fuel cell via a main bus terminal A charging/discharging unit executes charging or discharging of the high voltage battery. A power supply line is branched from the main bus terminal and connected to a load outside the vehicle to supply power of the fuel cell or the high voltage battery to the load outside the vehicle. A controller operates the fuel cell and the charging/discharging unit based on a magnitude in power supplied to the load outside the vehicle and a state of charge (SOC) of the high voltage battery.
