Abstract
The present disclosure relates to automobiles and, more specifically, teaches methods and systems that may be used for wirelessly charging batteries used in vehicles. In one embodiment, a method for detecting a relative position between a vehicle-side receiving charging coil and a fixed transmission charging coil, may include: 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.
