Vehicular power reception device, power supply apparatus, and electric power transfer system
First Claim
1. A vehicular power reception device for receiving electric power from a power source outside a vehicle, comprising:
- a first power reception unit receiving the electric power from said power source via a power line;
a second power reception unit receiving the electric power from said power source in a non-contact manner; and
a control unit controlling first electric power indicative of the electric power received by said first power reception unit and second electric power indicative of the electric power received by said second power reception unit such that the electric power received from said power source does not exceed electric power receivable by said vehicle,wherein said control unit controls said first electric power and said second electric power based on a sum of said first electric power and said second electric power.

Abstract
Contact charging is performed using a charging inlet and a charger, and non-contact charging is performed using a power transmission unit and a power reception unit. An ECU controls charging power by the contact charging and charging power by the non-contact charging such that the sum of the charging power by the contact charging and the charging power by the non-contact charging does not exceed a predetermined limitation. When the sum of electric power receivable by the contact charging and electric power receivable by the non-contact charging exceeds the predetermined limitation, the ECU controls the charging power by the contact charging and the charging power by the non-contact charging to limit one of the contact charging and the non-contact charging which is less efficient.

25. An electric power transfer system transferring electric power from a power supply apparatus to a vehicle, comprising:
-
a first power transmission/reception unit for transferring the electric power from said power supply apparatus to said vehicle via a power line; a second power transmission/reception unit for transferring the electric power from said power supply apparatus to said vehicle in a non-contact manner; and a control unit controlling first electric power indicative of the electric power transferred by said first power transmission/reception unit and second electric power indicative of the electric power transferred by said second power transmission/reception unit such that the electric power transferred from said power supply apparatus to said vehicle does not exceed electric power receivable by said vehicle, wherein said control unit controls said first electric power and said second electric power based on a sum of said first electric power and said second electric power.
