Abstract

A power supply system includes a vehicle, and a power feeding device for receiving power from the vehicle and feeding the received power to a load external to the vehicle. The vehicle includes a power generation unit, a power feeding unit for receiving power from the power generation unit and supplying the received power to the power feeding device, a storage unit for storing therein a specification of power supplied from an external power supply to the load, and a control device that controls the power feeding unit to convert power that is received from the power generation unit into power to drive the load, as based on the specification of the supplied power that is stored in the storage unit, once the external power supply has failed.

Claims

1. A power supply system comprising:

a vehicle; and

a power feeding device for receiving power from said vehicle and feeding the received power to a load external to said vehicle,

said load being configured to receive power supplied from an external power supply and be driven thereby and to also receive power from said vehicle and be driven thereby once said external power supply has failed,

said vehicle including

a power generation unit,

a power feeding unit for receiving power from said power generation unit and supplying the received power to said power feeding device.

a storage unit for storing therein a specification of power supplied from said external power supply to said load, and

a control device that stores said specification of the supplied power to said storage unit when said external power supply normally operates, and that also controls said power feeding unit to convert power that is received from said power generation unit into power to drive said load, as based on said specification of the supplied power that is stored in said storage unit, once said external power supply has failed.

2. The power supply system according to claim 1, said vehicle further including a communication unit for communicating with said power feeding device, wherein when said external power supply normally operates, said control device receives said specification of the supplied power from said power feeding device via said communication unit and stores said specification to said storage unit.

3. The power supply system according to claim 1, wherein:

said vehicle is configured to receive power that is supplied from said external power supply when said external power supply normally operates; and

said control device calculates said specification of the supplied power, as based on power supplied from said external power supply, and stores said specification to said storage unit.

4. The power supply system according to claim 1, wherein:

said power generation unit includes a rechargeable power storage device; and

said power feeding unit receives power discharged from said power storage device and converts the received power into power to drive said load.

5. The power supply system according to claim 1, said vehicle further including an internal combustion engine as a source of force to drive said vehicle, wherein:

said power generation unit includes

a rechargeable power storage device, and

a power generator configured to use an output of said internal combustion engine to generate power; and

said power feeding unit converts at least one of power discharged from said power storage device and power generated by said power generator into power to drive said load.

9. The power supply system according to claim 2, wherein:

said power generation unit includes a rechargeable power storage device; and

said power feeding unit receives power discharged from said power storage device and converts the received power into power to drive said load.

10. The power supply system according to claim 3, wherein:

said power generation unit includes a rechargeable power storage device; and

said power feeding unit receives power discharged from said power storage device and converts the received power into power to drive said load.

11. The power supply system according to claim 2, said vehicle further including an internal combustion engine as a source of force to drive said vehicle, wherein:

said power generation unit includes

a rechargeable power storage device, and

a power generator configured to use an output of said internal combustion engine to generate power; and

said power feeding unit converts at least one of power discharged from said power storage device and power generated by said power generator into power to drive said load.

12. The power supply system according to claim 3, said vehicle further including an internal combustion engine as a source of force to drive said vehicle, wherein:

said power generation unit includes

a rechargeable power storage device, and

a power generator configured to use an output of said internal combustion engine to generate power; and

said power feeding unit converts at least one of power discharged from said power storage device and power generated by said power generator into power to drive said load.

6. A vehicle capable of supplying power to a load external to the vehicle, said load being configured to receive power supplied from an external power supply and be driven thereby and to also receive power from the vehicle and be driven thereby once said external power supply has failed, the vehicle comprising:

a power generation unit;

a power feeding unit for receiving power from said power generation unit and supplying the received power to said load;

a storage unit for storing therein a specification of power supplied from said external power supply to said load; and

a control device that stores said specification of the supplied power to said storage unit when said external power supply normally operates, and that also controls said power feeding unit to convert power that is received from said power generation unit into power to drive said load, as based on said specification of the supplied power that is stored in said storage unit, once said external power supply has failed.

7. The vehicle according to claim 6, further comprising a communication unit for communicating outside the vehicle, wherein when said external power supply normally operates, said control device receives said specification of the supplied power from outside the vehicle via said communication unit and stores said specification to said storage unit.

8. The vehicle according to claim 6, wherein:

the vehicle is configured to receive power supplied from said external power supply when said external power supply normally operates; and

said control device calculates said specification of the supplied power, as based on power supplied from said external power supply, and stores said specification to said storage unit.
