NON-CONTACT POWER RECEPTION DEVICE AND VEHICLE INCLUDING THE SAME
First Claim
1. A non-contact power reception device comprising:
- a load identified as a subject of power feeding, anda secondary self-resonant coil receiving electric power to be supplied to said load from an external primary self-resonant coil,said secondary self-resonant coil being configured so as to be switchable between a first state and a second state, said first state being selected in a power reception mode in which said secondary self-resonant coil is magnetically coupled with said primary self-resonant coil through resonance of a magnetic field, and said second state being selected in a power non-reception mode in which magnetic coupling of said secondary self-resonant coil with said primary self-resonant coil through resonance is weaker than in said first state.

Abstract
A non-contact power reception device includes a load such as a power storage device (150) identified as a subject of power feeding, and a secondary self-resonant coil (110) receiving electric power to be supplied to said load from an external primary self-resonant coil (240). The secondary self-resonant coil (110) is configured so as to be switchable between a first state and a second state. The first state is selected in a power reception mode in which the secondary self-resonant coil is magnetically coupled with the primary self-resonant coil (240) through resonance of a magnetic field. The second state is selected in a power non-reception mode in which the magnetic coupling of the secondary self-resonant coil with the primary self-resonant coil through resonance is weaker than in the first state.

14. A vehicle comprising:
-
a non-contact power reception device receiving electric power transferred in a non-contact manner from outside said vehicle, wherein said non-contact power reception device includes a load identified as a subject of power feeding, and a secondary self-resonant coil receiving electric power to be supplied to said load from an external primary self-resonant coil, said secondary self-resonant coil being configured so as to be switchable between a first state and a second state, said first state being selected in a power reception mode in which said secondary self-resonant coil is magnetically coupled with said primary self-resonant coil through resonance of a magnetic field, and said second state being selected in a power non-reception mode in which magnetic coupling of said secondary self-resonant coil with said primary self-resonant coil through resonance is weaker than in said first state. - View Dependent Claims (15)
