1. A power feeding device for feeding power to an outlet provided in a vehicle, comprising:
- a power receiving unit receiving supply power supplied from an external power source external to the vehicle;
a rechargeable power storage device;
a charger provided between said power receiving unit and said power storage device, and configured to convert said supply power into charging power for said power storage device and charge said power storage device;
a switching circuit configured to switch between a first power feeding path for feeding power from said power receiving unit to said outlet and a second power feeding path for feeding power from said power storage device to said outlet; and
a control device controlling said switching circuit to switch between said first power feeding path and said second power feeding path, based on a result of comparison between a first evaluation value indicating a value of a predetermined index in a case where the power is fed to said outlet through said first power feeding path and a second evaluation value indicating a value of said index in a case where the power is fed to said outlet through said second power feeding path.

Abstract
A switching relay is configured to switch between a first power feeding path for feeding power from a charge inlet to an outlet and a second power feeding path for feeding power from a power storage device to the outlet. A PM-ECU controls the switching relay to switch between the first power feeding path and the second power feeding path, based on a result of comparison between a power cost in a case where the power is fed to the outlet through the first power feeding path and a power cost in a case where the power is fed to the outlet through the second power feeding path.

11. A power feeding method for feeding power to an outlet provided in a vehicle, said vehicle including
a power receiving unit receiving supply power supplied from an external power source external to the vehicle, a rechargeable power storage device, a charger provided between said power receiving unit and said power storage device, and configured to convert said supply power into charging power for said power storage device and charge said power storage device, and a switching circuit configured to switch between a first power feeding path for feeding power from said power receiving unit to said outlet and a second power feeding path for feeding power from said power storage device to said outlet, said power feeding method comprising the steps of: -
calculating a first evaluation value indicating a value of a predetermined index in a case where the power is fed to said outlet through said first power feeding path; calculating a second evaluation value indicating a value of said index in a case where the power is fed to said outlet through said second power feeding path; and switching between said first power feeding path and said second power feeding path by controlling said switching circuit based on a result of comparison between said first evaluation value and said second evaluation value. - View Dependent Claims (12, 13, 14, 15)
