摘要： In a first method (100) of providing a secondary reference for wireless power transfer measurements, an inanimate calibration object (50) is subjected (110) to electromagnetic field variations (38) by controlling operating points of a reference wireless power transmitter device (30). Key power absorption parameters (58) of the calibration object (50) resulting from the electromagnetic field variations (38) are generated (120) and stored (130) together with data (57) that defines the operating points in a data storage (52) being associated (54) with the calibration object (50). A second method (200) of evaluating a wireless power measurement device (DUT) then involves providing (210) an inanimate calibration object, and retrieving (220), from a data storage (52) associated with the calibration object (50), stored key power absorption parameters (58) for the calibration object together with data (57) that defines operating points. The second method (200) further involves subjecting (230) the calibration object (50) to electromagnetic field variations (68) by causing the wireless power measurement device (60, DUT) to operate at the operating points defined by the retrieved data (57), obtaining (240) key power absorption parameters of the calibration object resulting from the electromagnetic field variations (68); and comparing the obtained key power absorption parameters and the retrieved key power absorption parameters (58) to obtain a measurement result.

摘要： Disclosed is a method (310) for providing operational feedback during power transfer in a wireless power transfer system. The wireless power transfer system comprises a power transmit device arranged to transfer power over an inductive wireless power transfer interface operating at a transmit frequency to a power receive device. The wireless power transfer system is adapted to transfer information at half duplex using Frequency Shift Keying, FSK, in one direction and Amplitude Shift Keying, ASK, in the other direction. The method comprises transferring (308), at the transmit frequency by the power transmit device, power to the power receive device. During the transferring (308), the method further comprises transmitting (311), at the transmit frequency by one of the power transmit device or the power receive device, a first data packet to the other of the power transmit device or the power receive device using one of two modulation types being FSK or ASK. The method (310) further comprises receiving (311), by the other of the devices, the first data packet and, during the receiving (312) and if a signaling condition is determined (313) to be fulfilled, transmitting (314), at the transmit frequency, by the other of the devices to said one of the devices, operational information using the other of said modulation types. In addition to this, a power receive device, a power transmit device and a test system are introduced.
