ABSTRACT:
Disclosed is a wireless charging device for charging electronic devices placed in a docking area of the wireless charging device. The wireless charging device includes an inductive coupler, a reflected power detector, a power source and a power control system. The inductive coupler is configured to charge at least one electronic device present in the docking area. The inductive coupler takes power form the power source. The inductive coupler is also configured to communicate with the electronic device to exchange a set of information. The reflected power detector is operably coupled to the inductive coupler and identifies the set of information exchanged by the inductive coupler. The power control system is operably coupled to the reflected power detector and the power source. The power control system controls the charging of the electronic device by the power source based on the set of information identified by the reflected power detector.
