A New Calibration Strategy for Transfer-Power Measurement of Wireless Charging of Electric Vehicles

Accurate measurement is a hinge pin of a functioning society, engendering a sense of value, fairness, trust, and safety. A particularly salient example is wireless energy transfer to electric vehicles. A robust calibration method is needed for the fair and accurate measurement of the wireless power transferred to electric vehicles using the TPM (Transfer-Power Measurement)method. A prevalent obstacle to affordable, reliable, and accurate measurements in the field is lack of suitable transfer standards. This paper presents both a new transfer standard and a calibration path for TPM towards the standardization of power and energy metering in wireless power transfer.
