Scope

This Standard specifies the limits and test method of radiated emissions of electric and magnetic field
from electric vehicles over the frequency range of 9 kHz ~ 30 MHz, and the limits and test method of
conducted emissions over the frequency range of 450 kHz ~ 30 MHz.
Conducted emission measurements in this Standard are applicable only to battery-charging systems
which utilize a switching frequency above 9 kHz, which are mounted on the vehicle, and of which the
power is transferred by metallic conductors. Conducted emissions 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 Standard.
Note. GB 14023 shall govern, in the case of measurement of electromagnetic disturbances over the frequency range of 30
MHz ~ 1,000 MHz.

Summary	This standard specifies the electric vehicle 9kHz ~ 30MHz frequency range of magnetic and electric fields radiated emission limits and measurement methods, as well as in the frequency range of 450kHz ~ 30MHz for conducted emission limits and methods of measurement. This standard applies only to emission measurements conducted onboard battery charging system, its switching frequency should be above 9kHz, the energy transmitted through the metal conductor. Conducted emission technology requirements apply only through the AC power cord to the battery during the charging process. This standard does not include use of power inductive coupling device battery charging system for conducted and radiated emissions measurements.
