Abstract

A power supplying unit includes a power supply, a power supplying side resonant coil that resonates with a power receiving side resonant coil mounted on a vehicle and contactlessly supply the power supplied from the power supply to the power receiving side resonant coil, and a conductive power supplying side shield case for housing the power supplying side resonant coil. A power receiving unit includes the power receiving side resonant coil that electromagnetically resonates with the power supplying side resonant coil and contactlessly receive the power from the power supplying side resonant coil, and a power receiving side shield case for housing the power receiving side resonant coil. A ferrite is disposed outside the power receiving side shield case.

Claims

1. A power supplying unit comprising:

a power supply;

a power supplying side resonant coil that resonates with a power receiving side resonant coil mounted on a vehicle for contactlessly supplying power supplied from the power supply to the power receiving side resonant coil; and

a conductive shield case for housing the power supplying side resonant coil,

wherein the power supplying unit further has a magnetic body disposed outside the shield case.

3. A power supplying system comprising

a power supplying unit described in claim 1, and

a power receiving unit comprising:

a power receiving side resonant coil that is mounted on a vehicle and electromagnetically resonates with a power supplying side resonant coil for contactlessly receiving power from the power supplying side resonant coil; and

a conductive shield case for housing the power receiving side resonant coil,

wherein the power receiving unit further has a magnetic body disposed outside the shield case.

4. The power supplying system according to claim 3,

wherein the magnetic body is provided in a plate-like shape, and is disposed vertically to a separation direction of the power supplying side resonant coil and the power receiving side resonant coil at the time of supplying power.

2. A power receiving unit comprising:

a power receiving side resonant coil that is mounted on a vehicle and electromagnetically resonates with a power supplying side resonant coil for contactlessly receiving power from the power supplying side resonant coil; and

a conductive shield case for housing the power receiving side resonant coil,

wherein the power receiving unit further has a magnetic body disposed outside the shield case.
