SAE J551 specifies measurement procedures and performance levels for magnetic and electric field emissions and conducted power mains emissions over the frequency range of 150 kHz to 30 MHz for vehicles incorporating electric propulsion systems, e.g., battery, hybrid, or plug-in hybrid electric vehicles.
Conducted emissions measurements for SAE J551 apply only to battery-charging systems which utilize a switching frequency above 9 kHz, are mounted on the vehicle, and whose power is transferred by metallic conductors. Conducted emission requirements apply only during charging the batteries from AC power lines. Conducted and radiated emissions measurements of battery-charging systems that use an induction power coupling device are not covered by the SAE J551 document. The measurement of electromagnetic disturbances for frequencies from 30 MHz to 100 MHz is covered in CISPR 12.
