Abstract
A full duplex, low latency, near field data link controls a resonant induction, wireless power transfer system for recharging electric vehicles. An assembly of a vehicle is aligned with respect to a ground assembly to receive a charging signal. The vehicle assembly includes one or more coils, each coil having a full duplex inductively coupled data communication system that communicates with a ground assembly including one or more coils, with each coil also having a full duplex inductively coupled data communications system. The coils of the ground assembly and the vehicle assembly are selectively enabled based on geometric positioning of the vehicle assembly relative to the ground assembly for charging. As appropriate, the transmit/receive system of the ground assembly and/or the vehicle assembly are adjusted to be of the same type to enable communication of charging management and control data between the ground assembly and the vehicle assembly during charging.
