Power supply system and power feeding device
First Claim
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 power feeding device includinga communication unit for communication between said vehicle and said power feeding device, anda power supply unit that supplies said communication unit with power,said vehicle includinga 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, anda control device that controls said power feeding unit to convert the power received from said power generation unit into power to drive said load when said external power supply has failed,when said external power supply has failed, said power feeding device supplying the power that is received from said vehicle to said power supply unit to activate said communication unit, and said power feeding device also transmitting via said communication unit to said control device a specification regarding power supplied from said external power supply to said load,while said control device follows a predetermined specification to control said power feeding unit, once said specification regarding power supplied from said external power supply to said load has been received, said control device following said specification regarding power supplied from said external power supply to said load, rather than said predetermined specification, to control said power feeding unit.

Abstract
A power feeding device receives power from a vehicle and feeds the received power to a load external to the vehicle. A communication unit communicates between the vehicle and the power feeding device. A power supply unit supplies the communication unit with power. When an external power supply has failed, the power feeding device supplies the power that is received from the vehicle to the power supply unit to activate the communication unit, and the power feeding device also transmits via the communication unit to an ECU a specification regarding power supplied from the external power supply to the load. While the ECU follows a predetermined specification to control the power feeding unit, once the specification regarding power supplied from the external power supply to the load has been received, the ECU follows the received specification, rather than the predetermined specification, to control the power feeding unit.

6. A power feeding device for receiving power from a vehicle and feeding the received power to a load external to said vehicle, comprising:
-
a communication unit for communication between said vehicle and the power feeding device; a power supply unit that supplies said communication unit with power; and a switch unit configured to compare voltage on a power feeding line associated with an external power supply and voltage on a power feeding line associated with said vehicle and supply the voltage on said power feeding line that has voltage thereon to said power supply unit, wherein; when said external power supply has failed, and if there is voltage on said power feeding line associated with said vehicle, said switch unit supplies power that is received from said vehicle to said power supply unit; and when said communication unit receives the power from said power supply unit and is thus activated, said communication unit transmits to said vehicle a specification regarding power supplied from said external power supply to said load. - View Dependent Claims (7)
