The Administrative Council (AC) of the International Amateur Radio Union (IARU) believes high-power wireless power transfer (WPT) for electric vehicles has significant potential for interference with radio communication. That assessment came as the AC met on September 15 and 16 in Landshut, Germany, immediately prior to the IARU Region 1 Conference, to review its priorities and positions with regard to the 2019 World Radiocommunication Conference (WRC-19). Conference Agenda Item 9.1.6 would call for studies in advance of WRC-23 to assess the impact of WPT for electric vehicles on radiocommunication services and to study suitable harmonized frequency ranges to minimize its impact. The AC determined that addressing the threat requires an increased commitment of resources by potentially affected radiocommunication services, including Amateur Radio.
The WPT issue came up earlier this month at the meeting of CEPT WRC Project Team D, held in Vilnius, Lithuania, the week of September 11. At that gathering, IARU addressed the impact of spurious emissions from proposed high-power WPT systems for electric vehicles. IARU has expressed concern that current spurious emissions limits are not fit for this purpose in residential environments, and the potential impact on both Amateur Radio and broadcast reception is severe.
