Abstract:
This disclosure provides systems, methods, and apparatuses for controlling wireless charging between a first entity and a second entity. For example, the apparatus may include a receiver communication circuit of the first entity configured to receive a current from a second entity via electromagnetic induction during the charging or alignment with the second entity. The apparatus may include a frequency measurement circuit configured to determine an operating frequency of the received current or a voltage induced by the electromagnetic induction. The apparatus may include a controller configured to compare the operating frequency to a threshold and adjust an operation of the charging or the alignment based on the comparison.
