GB/T 18487.2-2001
Electric Vehicle Conductive Charging System Part 2: EMC Requirements for Off-board Electric Vehicle Supply Equipment
1 Scope
This part of GB/T 18487 specifies electromagnetic compatibility requirements for off-board conductive charging power supply equipment (hereinafter referred to as supply equipment) for electric vehicles. For power supply of supply equipment, the maximum rated voltage is 1000V AC or 1500V DC, and the maximum rated output voltage is 1000V AC or 1500V DC.
This part is applicable to supply equipment in charging modes 2, 3 and 4 specified in GB/T 18487.1.
This part is applicable to electric vehicle supply equipment obtaining energy from the on-site energy storage system (e.g. buffer battery).
It is considered in this part that cables without electronic elements or switches (except manual switches) are passive, and meet emission and immunity requirements, so test is not needed.
This part is not applicable to any on-board supply equipment, as well as parts and equipment in power supply system of electric vehicles.
This part is not applicable to supply equipment charging or supplying power for electric vehicles in wireless charging (WPT) mode.
This part is not applicable to trolley bus, railway vehicles, industrial vehicles and supply equipment mainly used for non-road vehicles.
