Technologies for wireless charging of electric vehicles
First Claim
1. A wireless charging system to control wireless charging of an electric vehicle, the wireless charging system comprising:
- a first power coil;
an actuator operatively coupled to the first power coil to move the first power coil;
a proximity sensor to produce sensor data indicative of a distance between the first power coil and a second power coil;
a power transfer controller to control, based on the distance, the actuator to move the first power coil toward the second power coil and control transfer of power (i) from the first power coil to the second power coil or (ii) from the second power coil to the first power coil.

Abstract
Technologies for wireless charging of an electric vehicle include moving a first coil toward a second coil based on a sensed distance between the first coil and the second coil. In an embodiment, the first coil is embodied as a power transmission coil that is moved toward the second coil, which is embodied as a power receiving coil located in the electric vehicle. The power transmission coil may be moved vertically from a roadway or other substrate beneath the electric vehicle. In another embodiment, the first coil may be embodied as the power receiving coil located in the electric vehicle that is moved downwardly from the electric vehicle toward the second coil, which is embodied as the power transmission coil. In such embodiments, the power transmission coil may be embodied in the roadway or other substrate beneath the electric vehicle. Additional technologies for controlling the movement and transfer of power of the coils are also disclosed.
