A device operative to transfer power and communicate wirelessly includes a drive-sense circuit (DSC), memory that stores operational instructions, and processing module(s). The DSC generates a drive signal based on a reference signal and provides the drive signal to a first coil via a single line and via a resonating capacitor, and simultaneously senses the drive signal via the single line, to facilitate electromagnetic coupling to a second coil to transfer power wirelessly to another device. The DSC also detects electrical characteristic(s) of the drive signal including whether a communication signal is transmitted from another device and generates a digital signal representative thereof. The processing module(s) generates the reference signal, processes the digital signal including to determine whether the communication signal is transmitted from the other device to the device and appropriately processes the digital signal to interpret control information of the communication signal to adapt the reference signal.

Described herein are techniques for providing authorization of vehicle charging requests in a manner that limits losses to unauthorized parties. Such techniques may comprise receiving, from a charging station, a request to access power resources, the request indicating a vehicle identifier, determining, based on the vehicle identifier, vehicle usage data for a vehicle associated with the vehicle identifier, determining expected usage data relevant to the request to access power resources, comparing the vehicle usage data to the expected usage data to identify a variance, and determining whether to authorize or decline the request to access power resources based on the identified variance.
