CHARGING DEVICE FOR VEHICLE
First Claim
1. A charging device for a vehicle for charging a power storage device mounted on a vehicle from an AC power supply outside the vehicle, comprising:
- an electric power reception terminal configured such that it can electrically be connected to said AC power supply;
a charger configured to convert AC Power input from said electric power reception terminal to a prescribed DC voltage;
a non-contact electric power reception portion configured to receive electric power in a non-contact manner from said AC power supply as a result of magnetic coupling to an electric power transmission portion of said AC power supply; and
a control device for controlling said charger to perform charging by using any greater one of first received electric power indicating electric power input from said electric power reception terminal and second received electric power indicating electric power received by said non-contact electric power reception portion.

Abstract
An electric power reception terminal is configured such that it can electrically be connected to an AC power supply. A charger is configured to convert AC power input from the electric power reception terminal to a prescribed DC voltage. A non-contact electric power reception portion is configured to receive electric power in a non-contact manner from an AC power supply as a result of magnetic coupling to an electric power transmission portion of the AC power supply. The non-contact electric power reception portion is connected to an electric power conversion circuit of the charger. A charge ECU compares conductive-reception electric power with non-contact-reception electric power, and controls the charger to perform charging by using any greater one of the conductive-reception electric power and the non-contact-reception electric power, based on a result of comparison.

5. A charging device for a vehicle for charging a power storage device mounted on a vehicle from an AC power supply outside the vehicle, comprising:
-
an electric power reception terminal configured such that it can electrically be connected to said AC power supply; a charger configured to convert AC power input from said electric power reception terminal to a prescribed DC voltage; a non-contact electric power reception portion configured to receive electric power in a non-contact manner from said AC power supply as a result of magnetic coupling to an electric power transmission portion of said AC power supply; and a control device for controlling said charger, said charger including a first rectifier unit configured to be able to rectify the AC power input from said electric power reception terminal, an inverter connected to said first rectifier unit, an isolation transformer connected to said inverter, and a second rectifier unit configured to rectify an output from said isolation transformer, said non-contact electric power reception portion including an electric power reception coil configured to magnetically be coupled to an electric power transmission coil provided in said electric power transmission portion, and a third rectifier unit configured to rectify an output from said electric power reception coil, said third rectifier unit being connected between said first rectifier unit and said inverter, and said control device adjusting a DC voltage between said first rectifier unit and said inverter between which said third rectifier unit is connected based on magnitude of electric power received by said non-contact electric power reception portion, when charging is performed by using electric power received by said non-contact electric power reception portion. - View Dependent Claims (6, 7, 10)
