Establishing trusted relationships for multimodal wireless power transfer

A method comprising:

• determining an operating mode of a first wireless power enabled device that includes a plurality of switches coupled in a full-bridge configuration with a resonant tank circuit, wherein the operating mode is selected from a receive mode and a transmit mode;
• establishing a trusted relationship between the first wireless power enabled device and a second wireless power enabled device;
• and
• when the determined operating mode is the receive mode, driving the plurality of switches to generate a wireless power signal that transmits power to the second wireless power enabled device.

A first wireless power enabled device comprising:

• a transceiver including a plurality of switches coupled in a full-bridge configuration with a resonant tank circuit;
• a secure storage that includes copies of two or more digital keys;
• and
• control logic configured to:
• detect a presence of a second wireless power enabled device;
• authenticate the second wireless power enabled device using the two or more digital keys;
• negotiate with the authenticated second wireless power enabled device to determine an operating mode of the first wireless power enabled device, the operating mode being selected from a transmit mode or a receive mode;
• drive the plurality of switches to operate the resonant tank circuit in the determined operating mode.
