ABSTRACT:
A wireless charging and power system for electronic devices and method for communicating power to a power receiver employing wireless energy transmission are disclosed. The remote charging system includes a power transmission unit, which transmits energy as a plurality of constructive transmitted frequencies, and a power receiver system that receives the transmitted frequencies. The power receiver system is preferably incorporated in a device and includes an energy receptor capable of receiving the wireless transmitted energy and transferring the energy from the transmitted frequencies to an energy storage device included in the device. The power transmission unit receives and tracks a power request signal from the power receiver system to track the power receiver system location during energy transmission. Data streams may be incorporated into the wireless signals of the remote charging system, allowing the remote charging system to function as a communications pathway as well as a power delivery system.
