POWER RECEIVING DEVICE, VEHICLE, AND CONTACTLESS POWER FEEDING SYSTEM
First Claim
1. A power receiving device configured to receive electric power that is transferred from a power transmitting device through electromagnetic resonance contactlessly, comprising:
- a power receiving unit configured to electromagnetically resonate with a power transmitting unit included in the power transmitting device to receive electric power from the power transmitting device;
a power storage device configured to store therein the electric power received by the power receiving unit; and
a light emitting unit configured to receive the electric power received by the power receiving unit to emit light, and vary in brightness with the electric power received,the electric power received by the power receiving unit varying according to positional displacement caused between the power transmitting unit and the power receiving unit.

Abstract
A contactless power feeding system includes a power transmitting device including a power transmitting unit and a power receiving device including a power receiving unit, and allows the power transmitting and receiving units to electromagnetically resonate with each other to supply electric power contactlessly. The power receiving device includes a power storage device for storing therein the electric power received by the power receiving unit, and a light emitting unit receiving the electric power received by the power receiving unit and emitting light, and varying in brightness according to the electric power received. The received electric power varies according to a positional displacement between the power transmitting unit and the power receiving unit. The user can recognize the positional displacement from information relevant to the brightness of the light emitting unit.
