Abstract
The disclosure relates to systems and methods for controlling a wireless power transfer system based upon Inductive Charging Technology using frequency based signaling communication protocol, operable to function in modes of Standby, Digital Ping, Identification, Power Transfer and End of Charge (EOC). The power transfer system comprising at least one wireless power outlet associated with a wireless power transmitter coil and at least one electrical device associated with a wireless power receiver coil, where the wireless power receiver coil is in multi-directional communication with the wireless power transmission of a message transmitter coil. The amount of power transferred is controlled by feedback communication between the receiver and the transmitter configured to increase or NO decrease power. More specifically, the present disclosure supports wireless power transfer incorporating transmission opportunity extended signaling supporting uni-directional and bi-directional communication enabling data transfer over extended range, higher power levels of power transfer and improved foreign object detection functionality.
