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 buried in a road, each power supply track including 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, and a plate or strip shaped insulating body positioned between the magnetic core and the magnetic field generator to isolate them from each other.
