본 발명은, 외부에 급전되는 전력을 계측하는 센서의 이상을 검지한 경우에 있어서도 외부에의 급전을 계속시키는 것을 과제로 한다. 차량에 탑재된 연료 전지 및 이차 전지로부터 외부에 전력을 공급하는 외부 급전 시스템의 제어 방법이다. 연료 전지와 이차 전지가 접속 가능한 전력 배선으로부터 외부에 급전되는 전력을 계측하는 센서의 이상을 검지한 경우에 있어서, (a) 이차 전지의 축전량의 감소가 검지되는 경우에는, 축전량의 감소를 멈추도록 연료 전지의 발전 전량을 증가시켜서 외부 급전을 행하고, (b) 이차 전지의 축전량의 증가가 검지되는 경우에는, 축전량의 증가를 멈추도록 연료 전지의 발전 전력을 감소시켜서 외부 급전을 행한다.

    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.
