Applying exploratively the international standard IEC CISPR36 to electric vehicles : radiated emissions produced by an electric vehicle and a plug-in hybrid vehicle

This technical report describes the results of an intensive test campaign involving two different electric vehicles. The first was a battery electric vehicle (i.e. fully electric) and the second was a plug-in hybrid electric vehicle. Both were tested in the Vehicle Emissions Laboratory (VELA) 9 electromagnetically semi-anechoic testing chamber. Radiated emissions produced by the vehicles under test within the frequency range 150 kHz to 30 MHz were evaluated in line with the international standard IEC CISPR 36:2020, with the evaluation even going beyond its requirements. This standard sets out the limits and methods of measurements for the protection of off-board receivers below 30 MHz. Test conditions that could potentially have an impact on measurement results and that could be of possible scientific interest, such as different vehicle positions, speeds, driving cycles and driving modes, were explored, as were potential common frequencies at which electromagnetic interference might be present. In order to create a more comprehensive and realistic picture of the different electric vehicle technologies currently available, the two types of electric vehicles that require assessment using the IEC CISPR 36:2020 standard (i.e. battery electric vehicles and plug-in hybrid electric vehicles) were selected. The activity was part of the Joint Research Centre's VELA 9 work regarding radiated emissions generated by vehicles, which focuses on ever more realistic conditions with regard to geometrical set-up and dynamic driving conditions.
