systems, methods and apparatus for guiding and aligning inductive wireless charging systems for electric vehicles

摘要

It is an apparatus for determining a relative position of a wireless power transmitter from a wireless power receiver. the apparatus comprises a plurality of sensing coils, each of which is configured to generate a respective signal under the influence of an alternating magnetic field comprising a plurality of wave pulses, each wave pulse occurring within a time interval. respective one of a plurality of time slots. The apparatus further comprises a processor configured to determine the relative position of the wireless power transmitter from the wireless power receiver based on the respective signal from each of the plurality of detection coils.
