IARU Region 1 President Warns of QRM from Wireless Power Chargers for Electric Cars

Speaking of IARU Region 1 (which covers Europe, Africa and the Middle East), region President Don Beattie, G3BJ, is warning of tremendous interference potential from wireless charging systems for electric vehicles. According to the ARRL Letter, Beattie notes that these charging systems, which are similar to wireless charging systems for cell phones but operating at power levels of 20 kilowatts or more, may generate harmonics causing interference on a wide range of frequencies. He urged IARU member societies to discuss these issues with their national regulators, noting that discussions about WPT-EV (wireless power transfer for electric vehicles) "have reached a point where they are moving from the technical to the political arena."
