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,wherein each of the power generating elements includesa core made of an electromagnetic material and disposed such that one end surface thereof is in contact with the inner peripheral surface of the tire and the other end surface is opposed to a rotational center of the tire, anda power generating coil made of an electrical conductive material and wound around a side surface of the core, the power generating coil having opposite ends each electrically connected to the power distribution system.

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.
