Ultra slim power supply device and power acquisition device for electric vehicle
First Claim
1. An ultra slim power supply device for supplying power to an electric vehicle in a contactless manner, comprising:
- at least one power supply track including a plate or strip shaped magnetic core extending along a road, the magnetic core being in the shape of a square bracket open upward, a magnetic field generator arranged above the magnetic core through which an alternating current is supplied to generate a magnetic field, and an insulating body positioned between the magnetic core and the magnetic field generator to isolate them from each other,wherein the magnetic core is arranged such that two uppermost ends of the magnetic core become coplanar with a surface of the road, and wherein a material having a composition identical to that of the road is filled in an inner space between the uppermost ends.

Abstract
An ultra slim power supply device for supplying power to an electric vehicle in a contactless manner includes at least one power supply track buried in a road. Each power supply track includes a plate-shaped magnetic core extending along the road, a plate or strip shaped magnetic field generator arranged above the magnetic core through which an alternating current is supplied to generate a magnetic field, a plate or strip shaped insulating body positioned between the magnetic core and the magnetic field generator to isolate them from each other, and a housing for enclosing the magnetic core, the magnetic field generator and the insulating body.
