Abstract

A vehicle includes a coil (22) receiving electric power contactlessly from a power transmission unit (56) provided externally; and a bottom surface. The coil (22) is formed to surround a winding axis (O1) of the coil (22). When the winding axis (O1) and the bottom surface (76) are viewed from above the vehicle, the coil (22) is disposed such that the winding axis (O1) located to fall within the bottom surface (76) is shorter in length than the vehicle in a front-rear direction.

First claim

The invention claimed is:

1. A vehicle comprising:
a first wheel and a second wheel arranged in a width direction of the vehicle;
a refueling portion configured to connect to an external refueling plug, wherein the refueling portion is disposed on a first side surface of the vehicle;
a charging portion configured to connect to an external charging plug, wherein the charging portion is disposed on a second side surface of the vehicle, wherein the first side surface and the second side surface are surfaces that are viewable from a position outside of the vehicle,
wherein the refueling portion and the charging portion are located only at a rear side relative to a center of said vehicle in a front-rear direction of the vehicle; and
a first coil and a second coil each receiving electric power contactlessly from a power transmission unit provided externally,
the first coil being formed to surround a first winding axis extending in a vertical direction,
the second coil being formed to surround a second winding axis extending in the vertical direction,
the first coil and the second coil being formed such that a current direction in a winding direction of the first coil and a current direction in a winding direction of the second coil are opposite to each other during power reception,
an electromagnetic field being formed around the first coil and the second coil,
wherein the first coil and the second coil are located at a front side relative to the center of said vehicle in the front-rear direction,
wherein the first coil and the second coil are disposed between the first front wheel and the second front wheel along a virtual plane in the width direction of the vehicle, wherein the virtual plane in the width direction of the vehicle intersects the first front wheel and the second front wheel, and
wherein the electromagnetic field is distributed wider in the width direction of the vehicle than in a traveling direction of the vehicle.

2. A vehicle comprising:
a first wheel and a second wheel arranged in a width direction of the vehicle;
a refueling portion configured to connected to an external refueling plug, wherein the refueling portion is disposed on a first side surface of the vehicle;
a charging portion configured to connected to an external charging plug, wherein the charging portion is disposed on a second side surface of the vehicle, wherein the first side surface and the second side surface are surfaces that are viewable from a position outside of the vehicle,
wherein the refueling portion and the charging portion are located only at a rear side relative to a center of said vehicle in front-rear direction of the vehicle; and
a first coil and a second coil each receiving electric power contactlessly from a power transmission unit provided externally,
the first coil being formed to surround a first winding axis extending in a vertical direction,
the second coil being formed to surround a second winding axis extending in the vertical direction,
the first coil and the second coil being formed to be symmetric with respect to a virtual plane located between the first and the second coil, the virtual plane being parallel with a traveling direction of the vehicle,
an electromagnetic field being formed around the first coil and the second coil,
wherein the first coil and the second coil are located at a front side relative to the center of said vehicle in the front-rear direction,
wherein the first coil and the second coil are disposed between the first front wheel and the second front wheel along another virtual plane in the width direction of the vehicle, wherein the another virtual plane in the width direction of the vehicle intersects the first front wheel and the second front wheel, and
wherein the electromagnetic field is distributed wider in the width direction of the vehicle than in the traveling direction of the vehicle.
