Abstract

A vehicle includes: a power reception unit that receives electric power contactlessly from a power transmission unit externally provided; and an electronic device. The power reception unit includes a coil formed to surround a winding axis. Assuming that a region extending in a direction in which the winding axis extends from the coil when viewing the coil from above the vehicle is an adjacent region, the electronic device is away from the adjacent region.

Claims

1. A vehicle comprising:

a power reception unit including a coil that receives electric power contactlessly from a power transmission unit externally provided; and

a battery,

an electromagnetic field formed by transfer of electric power between said power reception unit and said power transmission unit being distributed more widely from said coil in a width direction of said vehicle than in a front-back direction of said vehicle,

the vehicle including one end surface and an other end surface that are arranged in the front-back direction of said vehicle, and a camera disposed at the one end surface,

the power reception unit being provided at a position on said vehicle that is closer to the one end surface than the other end surface,

said battery being disposed in a region in said front-back direction of said vehicle from said coil, so as to be provided between said power reception unit and the other end surface,

a distance in the vehicle longitudinal direction between said power reception unit and said battery is longer than a distance between said power reception unit and the camera.
