ELECTRIC VEHICLE AND ELECTRIC SUPPLY ARRANGEMENT FOR THE SAME
First Claim
1. An electric vehicle comprising:
- a plurality of power generating elements disposed in an internal space region of a tire of each of a plurality of wheels in such a manner as to come into contact with the inner peripheral surface of the tire over an entire circumference of an annular-shaped inner peripheral surface of the tire, and each adapted to generate electric power by electromagnetic induction caused by a periodical change in magnetic field applied from the side of a road surface; and
a motor adapted to be rotated by electric power supplied from the power generating elements through a power distribution system, and to rotationally drive the wheels through a driving-force transmission mechanism.

Abstract
In an electric vehicle, a power unit is installed in an internal space region of a tire of each of front and rear wheels. The unit has a plurality of power elements arranged on an inner peripheral surface of a ground contact portion of the tire. Each of the elements includes a core made of a permalloy, and a power coil wound around the core. When a periodically-changing magnetic field is generated in a region above a road by an electric supply arrangement installed in the road, each of the elements generates electric power. This electric power is supplied to a motor of the vehicle through a power distribution system. The motor drives front wheels. The electric vehicle can continuously run over long distances without charging a battery at a buttery station.
