Performance Levels and Methods of Measurement of Magnetic and Electric Field Strength from Electric Vehicles, Broadband,9 kHz To 30 MHz
The test procedures and performance levels in this SAE Recommended Practice cover the
measurement of magnetic and electric field strengths over the frequency range 9 kHz to 30
MHz and conducted emissions over the frequency range of 450 kHz to 30 MHz .
Conducted emission measurements in this document are applicable 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 of 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 this document.
The measurement of electromagnetic disturbances for frequencies from 30 MHz to 1000 MHz and
narrowband electromagnetic disturbances for frequencies from 150 KHz to 30 MHz are covered
in SAE J551-2.
