Abstract

A testing system (90) for use in testing of wireless power transfer is disclosed. The testing system has at least one wireless power receiver circuit (34) for receiving inductive power from an external wireless power transmitter (20). The testing system is arranged to detect received inductive power at least two operating frequencies relating two both a wireless power standard and a wireless communication standard. Measurements data originating from inductive power received adopting the wireless communication standard is forwarded to a processing means (42) which based on reference data is arranged to detect whether a communication receiver circuit (15) and arranged to communicate according to the wireless communication standard adopting the second frequency range, when arranged in operative proximity to the external wireless power transmitter device (20), would be negatively affected by the inductive power transmitted from the external wireless power transmitter device (20).

Description

technical field [0001] The present invention relates generally to the field of wireless power transfer, and more particularly to testing of wireless power transfer. More specifically, the present invention relates to a test system capable of detecting whether an external device would be adversely affected if placed near an external wireless power transmitter device while operating in its inductive charging mode, the external device Comprising a specific communication receiver circuit arranged to communicate according to a wireless communication standard and a wireless power receiver coil operating according to a conventional wireless power transfer standard for receiving inductive power. Background technique [0002] Wireless power transfer is expected to become increasingly popular, e.g. for mobile devices such as mobile terminals, tablet computers, notebook computers, cameras, audio players, rechargeable toothbrushes, wireless headsets, and various other consumer products ...
