GB/T 18387-2008 Limits and test method of magnetic and electric field strength from electric vehicles,broadband,9 kHz to 30 MHz
Basic Information
Scope
This standard specifies the limits and measurement methods for radiation emissions from magnetic and electric fields in the frequency range of 9 kHz to 30 MHz in electric vehicles, as well as the limits and measurement methods for conduction emissions in the frequency range of 450 kHz to 30 MHz. The conduction emission measurement in this standard only applies to on-board battery charging systems, whose switching frequency should be above 9 kHz, and energy is transmitted through metal conductors. The technical requirements for conduction emissions only apply during the battery charging process via AC power lines. This standard does not include the measurement of conduction and radiation emissions for battery charging systems using power induction coupling devices. Note: For electromagnetic interference measurements in the frequency range of 30 MHz to 1,000 MHz, GB 14023 is used.
