Wireless charging for vehicle batteries
First Claim
1. A method for detecting a relative position between a vehicle-side receiving charging coil and a fixed transmission charging coil, the method comprising:
- generating an alternating magnetic orientation field using one of the coils;
detecting the orientation field using at least one coil provided for inductive excitation, wherein the orientation field is detected in a frequency-selective manner by the at least one coil; and
ascertaining the relative position using an orientation receiving signal induced by the orientation field in the at least one coil.
