DEVICES, SYSTEMS, AND METHOD FOR DYNAMIC ELECTRIC VEHICLE CHARGING WITH POSITION DETECTION
First Claim
1. An apparatus for wirelessly charging an electric vehicle, comprising:
- at least one charging circuit configured to generate a wireless field at a power level sufficient to charge the electric vehicle;
at least one proximity device configured to generate a proximity signal upon detecting an arrival of the electric vehicle at the at least one charging circuit, the detecting of the arrival based at least in part on detecting a change in an electrical characteristic of the at least one charging circuit, the change based on a change in distance of the electric vehicle from the at least one charging circuit; and
a processor configured to generate a signal controlling an activation or deactivation of the at least one charging circuit in response to receiving the proximity signal from the at least one proximity device.

Abstract
Systems, methods, and apparatus are disclosed for wirelessly charging an electric vehicle. In one aspect, a method of wirelessly charging an electric vehicle is disclosed. The method includes generating a wireless field at a power level sufficient to charge the electric vehicle by at least one charging circuit comprising at least one coil. The method further includes detecting an arrival of the electric vehicle at the at least one charging circuit, the detection of the arrival of the electric vehicle determined based on a level of current flowing through the at least one coil. The method further includes generating a proximity signal upon the detection of the arrival of the electric vehicle at the at least one charging circuit.
