    Abstract: A wireless charging apparatus and method utilizing a secure element is disclosed. Illustratively, a receiver containing a secure element securely communicates with a charging pad also equipped with a secure element. The communication can be used to establish the identity of the receiver and facilitate billing for the wireless charging. The charging pad may further communicate in a secure manner with a server to authenticate the identity and other information about the receiver before providing wireless charging. Direct communication between the receiver and server is also contemplated.

    Abstract: A method for performing foreign object detection in an inductive wireless power transfer system is disclosed. In the embodiment, the method involves obtaining measurements from a base station of a wireless power transfer system during charging and determining transmitter energy loss in a power transmitter, Ptxloss, using the obtained measurements, wherein the transmitter energy loss, Ptxloss, is a function of at least Vcap and PTx, wherein Vcap is proportional to the voltage amplitude across the capacitor of an LC tank circuit in a power transmitter and PTx is the total power supplied to the power transmitter. The method also involves detecting the presence of a foreign object in response to the estimated transmitter energy loss.
