Wireless charging interference mitigation

Abstract:

An electronic device such as a portable electronic device has wireless power receiving circuitry. A vehicle has a vehicle remote keyless system that transmits beacons. A key receives the beacons and responds with key codes to unlock doors and enable a vehicle ignition in the vehicle. In the presence of wireless power transfer operations there is a risk that wireless power signals will interfere with the reception of the beacons by the key. To ensure that beacons are satisfactorily received, conditions in which there is a risk of interference are detected and corresponding interference mitigation operations are performed.
