Abstract: Systems, methods, and apparatuses for receiving charging power wirelessly are described herein. One implementation may include an apparatus for receiving charging power wirelessly from a charging transmitter having a transmit coil. The apparatus comprises a receiver communication circuit, coupled to a receive coil and to a load. The receiver communication circuit is configured to receive information associated with at least one characteristic of the charging transmitter. The apparatus further comprises a sensor circuit configured to measure a value of a short circuit current or an open circuit voltage associated with the receive coil. The apparatus further comprises a controller configured to compare the value of the short circuit current or the open circuit voltage to a threshold charging parameter set at a level that provides charging power sufficient to charge the load. The controller may be further configured to initiate receiving the charging power from the charging transmitter when the short circuit current or the open circuit voltage associated with the receive coil is greater than or equal to the threshold charging parameter.
