  • ELECTRIC VEHICLE AND ELECTRIC SUPPLY ARRANGEMENT FOR THE SAME
    Publication number: 20140131121
    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.
