Abstract
There is provided a control method of an external power supply system configured to supply power to the outside from a fuel cell and a secondary battery mounted on a vehicle. When a failure is detected in a sensor that measures an electric power supplied to the outside from an electric power line to which the fuel cell and the secondary battery are connectable, (a) if a decrease in a state of charge of the secondary battery is detected, external power supply is performed by increasing a generated power of the fuel cell so as to stop the decrease in the state of charge, and (b) if an increase in a state of charge of the secondary battery is detected, external power supply is performed by decreasing the generated power of the fuel cell so as to stop the increase in the state of charge.
