Abstract

Methods and systems for precision charging control of a vehicle include at least a wireless charging antenna carried by a vehicle and in electrical communication with a vehicle propulsion system. A plurality of wireless charging antennae is associated with a charging surface and is in communication with at least a control system and a power source. An authentication connection is established between the vehicle wireless charging antenna and the control system which uses a timestamping technique. The wireless charging antenna carried by the vehicle is paired with one or more of the plurality of wireless charging antennae associated with the charging surface by triggering a dynamic seek operation or establishing a connection based on a timestamped location point. Transfer of a quantity of electrical energy between the first wireless charging antenna and the one of the plurality of second wireless charging antennae is adaptively controlled.
