Abstract
A partially magnetized pavement is placed above a transmitter coil for improved efficiency of electric vehicles charging through wireless power transfer. The partially magnetized pavement includes a non-magnetized pavement portion positioned vertically above the transmitter coil and a magnetized pavement portion positioned vertically above a first area surrounded by the inner dimension of the transmitter coil and a second area outside the outer dimension of the transmitter coil. In some cases, the partially magnetized pavement further includes a transmitter coil having the inner dimension and the outer dimension and a capacitor electrically coupled to the transmitter coil to form a resistor-inductor-capacitor circuit at a system level. In some cases, a plurality of electric vehicle charging units are positioned in a center of a lane in a roadway and separated from one another by a predetermined distance along a direction of the lane in the roadway.
