Abstract

An authentication between a wireless charger and a device configured to receive wireless energy from the wireless charger includes establishing a wireless data channel between the wireless charger and the device. An authentication challenge signal is driven onto a transmit charging coil of the wireless charger and a receive charging coil of the device is configured to receive the authentication challenge signal. The device sends an authentication response signal to the wireless charger based at least in part on the authentication challenge signal.
