Abstract: Various methods, apparatuses and systems are directed to battery-charging applications. As may be consistent with one or more embodiments discussed herein, a charging current for charging a battery is modulated, and the frequency of the modulated charging current is set based upon an impedance of the battery. Temperature of the battery is estimated based upon the impedance exhibited by the battery, while the battery is charged with the modulated charging current. In various implementations, the battery charging rate is controlled based on the estimated temperature.

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.
