1. A wireless power transfer system for a vehicle, the system comprising:
a direct current (DC) electrical power source including at least one battery unit;
a high-frequency alternating current (HFAC) inverter electrically coupled to the DC electrical power source;
a transmitter electrically coupled to the HFAC inverter; and
a controller electrically coupled to the HFAC inverter and the transmitter, wherein the controller is configured to
enable the HFAC inverter and the transmitter,
control the transmitter to generate a data signal,
control the HFAC inverter and the transmitter to wirelessly transmit a HFAC power signal to at least one device of a vehicle, and
wherein:
the data signal is superimposed on the transmitted HFAC power signal, and
the HFAC power signal provides wireless power to the at least one device.
