Abstract

A power reception unit includes a secondary self-resonant coil receiving electric power from a power transmission unit of a power feeding device by resonating with a primary self-resonant coil included in the power transmission unit through an electromagnetic field. The power reception unit is stored in an engine room where a driving power generation unit including an engine and motor generator are stored. In detail, the power reception unit is arranged at the bottom of the engine room. A shielding member is provided to electromagnetically shield the engine room from inside and outside. For example, the shielding member is formed of a cloth, sponge, or the like having an electromagnetic shielding effect, and is arranged at the inner surface of the engine room.

Claims

1. An electrical powered vehicle capable of generating running driving power by an electric motor using electric power supplied from a power feeding device provided external to the vehicle, comprising:

a power reception unit including a power reception resonator receiving electric power from a power transmission resonator included in said power feeding device by resonating with said power transmission resonator through an electromagnetic field,

a storage chamber where said power reception unit is stored, and

a shielding member electromagnetically shielding said storage chamber from inside and outside.

2. The electrical powered vehicle according to claim 1, further comprising an internal combustion engine generating energy for running,

wherein said storage chamber is an engine room where said internal combustion engine is stored.

3. The electrical powered vehicle according to claim 1, wherein said storage chamber is a luggage compartment for storing a luggage of a user.

4. The electrical powered vehicle according to claim 1, wherein said storage chamber is a chamber where said electric motor is stored.

5. The electrical powered vehicle according to claim 1, further comprising an electric power conversion device carrying out power conversion between a power supply line in the vehicle and said electric motor,

wherein said storage chamber is a chamber where said electric power conversion device is stored.

6. The electrical powered vehicle according to claim 1, wherein said power reception unit is arranged at a bottom of said storage chamber.

7. The electrical powered vehicle according to claim 1, further comprising:

a door for opening and closing said storage chamber, and

an interlock mechanism for interrupting or prohibiting power reception from said power feeding device when said door attains an open state.

8. The electrical powered vehicle according to claim 7, wherein said interlock mechanism includes

a detection device detecting an open/close state of said door, and

a communication device transmitting to said power feeding device a command designating interruption or prohibition of power transmission from said power feeding device when an open state of said door is detected by said detection device.

9. The electrical powered vehicle according to claim 2, wherein said power reception unit is arranged at a bottom of said storage chamber.

10. The electrical powered vehicle according to claim 3, wherein said power reception unit is arranged at a bottom of said storage chamber.

a door for opening and closing said storage chamber, and

an interlock mechanism for interrupting or prohibiting power reception from said power feeding device when said door attains an open state.

14. The electrical powered vehicle according to claim 3, further comprising:

a door for opening and closing said storage chamber, and

an interlock mechanism for interrupting or prohibiting power reception from said power feeding device when said door attains an open state.

15. The electrical powered vehicle according to claim 4, further comprising:

a door for opening and closing said storage chamber, and

an interlock mechanism for interrupting or prohibiting power reception from said power feeding device when said door attains an open state.
