Abstract

An FCV includes an FC system and a battery. The FC system includes an FC stack and a boost converter that adjusts output from the FC stack. An FDC-ECU controls the boost converter to adjust an SOC of the battery to a target SOC while electric power is supplied from the FC stack to an inverter. Then, the FDC-ECU lowers the target SOC with decrease in remaining amount of hydrogen in a hydrogen tank.

Claims (17)

1. A fuel cell vehicle comprising:

a fuel cell system output of which can be adjusted;

a power storage;

a driving device that receives electric power from at least one of the fuel cell system and the power storage and generates travel power; and

a controller that controls output from the fuel cell system to adjust an SOC of the power storage to a target SOC while electric power is supplied from the fuel cell system to the driving device, wherein

when a remaining amount of fuel in the fuel cell system decreases, the controller lowers the target SOC.

2. The fuel cell vehicle according to claim 1 , wherein

when the remaining amount of fuel becomes smaller than a threshold value, the controller lowers the target SOC with decrease in the remaining amount of fuel.

3. The fuel cell vehicle according to claim 1 , wherein

the controller lowers the target SOC with decrease in the remaining amount of fuel such that the target SOC attains to a lower limit value at timing when fuel in the fuel cell system runs out.

4. The fuel cell vehicle according to claim 1 , wherein

the fuel cell system includes

a tank where fuel is stored,

a fuel cell stack that generates electric power with fuel stored in the tank, and

a converter that adjusts output from the fuel cell stack, and

the power storage is electrically connected to a power line between the converter and the driving device.

5. The fuel cell vehicle according to claim 1 , further comprising a charger that charges the power storage with a power supply outside the vehicle.
