Abstract
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.
