CISPR 36: “Electric and hybrid electric road vehicles - Radio disturbance characteristics - Limits and methods of measurement for the protection of off-board receivers below 30 MHz”
CISPR 36 is a relatively new standard, with its first official release in 2020. You can purchase a copy here. While it is strongly influenced by an earlier Chinese standard, GB/T 18387, CISPR 36 has a narrower frequency range, starting at 150 kHz instead of 9 kHz. It stops at 30 MHz, which is where CISPR 12 picks up.
CISPR 36 is unusual in focusing on low frequency magnetic fields, although its purpose is still to protect the radio reception of receivers outside the vehicle. On board receivers are protected by CISPR 25, same as any other vehicle. CISPR 36 only applies to ground vehicles with electric motors that draw power from a traction battery with voltage between 100 and 1000 V.
CISPR 36 uses magnetic field (loop) antennas positioned 3 m away from the vehicle. Measurements are taken with the vehicle at speed (on a dynamometer) at four positions (in front, behind, and to either side of the vehicle) and two orientations, for a total of eight sweeps. The sweeps are from 150 kHz - 30 MHz with a resolution bandwidth of 9 kHz. The limits are the magnetic field strength in dBuA/m, taken as a quasi peak (QP) measurement. In general most test operators will sweep in peak detection mode first, and only return to take QP measurements at specific frequencies where the peak value is above the QP limit. (See our explainer on quasi peak measurements.) Measurements can be taken in a semianechoic chamber or properly characterized open air test site, not in a reverb chamber.
Right now CISPR 36 does not address the charging mode, either via plug in or wireless power transfer (WPT). Other committees are looking into those modes, and ANSI C63.30 was published in 2021 describing test methods for WPT specifically.
