Abstract

A wireless power transmission device includes a power-supplying coil configured to wirelessly transmit power to an electric vehicle (EV) serving as a vehicle, be installed in a slanted state or perpendicularly to a horizontal plane, and form an electromagnetic coupling circuit along with a power-receiving coil provided in the EV.

First claim

1 . A wireless power transmission device to wirelessly transmit power to a vehicle, the wireless power transmission device comprising:
a power-supplying coil installed in a slanted state or perpendicularly to a horizontal plane and configured to form an electromagnetic coupling circuit along with a power-receiving coil provided in the vehicle.

2 . The wireless power transmission device according to claim 1 , wherein the power-supplying coil is provided in a plate-like container having at least one surface on which a fluororesin coating film is formed.

3 . The wireless power transmission device according to claim 1 , wherein the power-supplying coil is provided in a plate-like container having at least one surface on which a large number of micro projections are formed.

4 . The wireless power transmission device according to claim 1 , wherein the power-supplying coil is provided in a plate-like container having at least one surface on which a large number of grooves extending in a slanted direction are formed.

5 . The wireless power transmission device according to claim 1 , wherein the power-supplying coil is installed in a state in which at least an upper end portion projects from an installation surface, in a place into which entry of the vehicle is inhibited by a vehicle stopper.

6 . The wireless power transmission device according to claim 1 , the power-supplying coil is installed at a stopping position at which the vehicle should stop, in a state in which the entire power-supplying coil is embedded below an installation surface.

7 . A vehicle configured to receive power wirelessly transmitted from the outside, the vehicle comprising:
a power-receiving coil configured to face the power-supplying coil provided in the wireless power transmission device according to claim 1 and form the electromagnetic coupling circuit along with the power-supplying coil.

8 . A vehicle configured to receive power wirelessly transmitted from the outside, the vehicle comprising:
a power-receiving coil provided in a bottom of the vehicle and configured to form the electromagnetic coupling circuit along with the power-supplying coil provided in the wireless power transmission device according to claim 1 .

9 . A vehicle configured to receive power wirelessly transmitted from the outside, the vehicle comprising:
a power-receiving coil configured to face the power-supplying coil provided in the wireless power transmission device according to claim 5 and form the electromagnetic coupling circuit along with the power-supplying coil.

10 . A vehicle configured to receive power wirelessly transmitted from the outside, the vehicle comprising:
a power-receiving coil configured to face the power-supplying coil provided in the wireless power transmission device according to claim 6 and form the electromagnetic coupling circuit along with the power-supplying coil.

11 . A vehicle configured to receive power wirelessly transmitted from the outside, the vehicle comprising:
a power-receiving coil provided in a bottom of the vehicle and configured to form the electromagnetic coupling circuit along with the power-supplying coil provided in the wireless power transmission device according to claim 5 .

12 . A vehicle configured to receive power wirelessly transmitted from the outside, the vehicle comprising:
a power-receiving coil provided in a bottom of the vehicle and configured to form the electromagnetic coupling circuit along with the power-supplying coil provided in the wireless power transmission device according to claim 6 .
