Abstract
There are provided: a power supply provided with a fuel cell; a fuel cell vehicle; an inverter device capable of supplying electric power that is supplied from the fuel cell to an external load; a radiator; a radiator fan; a dryness detection device that detects a dry condition of the fuel cell; and an ECU that control supply of electric power to the external load. The ECU drives the radiator fan when the dryness detection device detects dryness of the fuel cell while electric power is being supplied from the fuel cell to the external load.
Claims4
An electric power supply system comprising:
- a power supply provided with a fuel cell that generates electric power with a fuel gas and an oxidant gas;
- a vehicle that is driven with electric power supplied from the power supply;
- an external power feeding circuit configured to supply electric power supplied from the power supply to an external load in a state where the vehicle is stopped;
- a radiator that releases heat of a coolant for cooling the fuel cell;
- a radiator fan that blows air to the radiator;
- a dryness detection device that detects a dry condition of the fuel cell;
- and
- a control device that controls supply of electric power to the external load, wherein
- the external power feeding circuit connects a power feed opening provided in the vehicle and the external load outside the vehicle to supply electric power, is provided as a separate device from the vehicle, and is formed so as to be moved separately from the vehicle, and
- the control device is programmed to cool the fuel cell by causing the radiator fan to drive in a case where the dryness detection device detects dryness of the fuel cell while electric power is being supplied from the power supply to the external load in the state where the vehicle is stopped after it is determined that the vehicle is in an external power feeding state based on a connection state between the power feed opening and the external power feeding circuit.
