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;
a first communication unit for communicating first information about power reception by said first power reception unit with an outside of the vehicle;
a second communication unit for communicating second information about power reception by said second power reception unit with the outside of the vehicle; and
,a control unit controlling said first and second communication units, when power reception from said power source is performed using both of said first and second power reception units, to communicate common information with the outside of the vehicle using only one of said first and second communication units, said common information being information in common with each other in information contained in said first information and information contained in said second information.

Abstract
A contact charging circuit composed of a charging inlet and a charger receives electric power from an outside power source via a charging cable. A non-contact charging circuit composed of a power reception unit, a rectifier, and a sensor unit receives electric power from an outside power source in a non-contact manner. A first communication device communicates contact charging information about power reception by the contact charging circuit with a third communication device of a power supply apparatus. A second communication device communicates non-contact charging information about power reception by the non-contact charging circuit with a fourth communication device of the power supply apparatus.
