GB/T 18487 “Electric vehicle conductive charging system “covers the following three parts: Part 1: General requirements Part 2: EMC requirements for off-board electric vehicle supply equipment Part 3: A.C./D.C.Electric vehicle charging station This part is Part 2 in GB/T 18487. This part was developed in accordance with the rules given in GB/T 1.1-2009. This part replaces “Electric Vehicle Conductive Charging System-Electric Vehicles Requirements for Conductive Connection to an A.C/D.C. Supply” (GB/T 18487.2-2001). Compared with GB/T 18487.2-2001, in addition to the editorial changes, this standard has the following major technical changes: ——since the content of supply equipment is added, the title of this part is changed to “EMC requirements for off-board electric vehicle supply equipment ” ——The Requirements of Supply Equipment Configuration is added (See Chapter 4) ——The Test Load Condition of Supply Equipment is added (See Chapter 5) ——The Operation Condition during the Testing is added (See Chapter 6) ——The Immunity Requirements is added (See Chapter 7) ——The O Emission Requirements is added (See Chapter 8) This part was proposed by and is under the jurisdiction of the China Electricity Council. The previous edition of this standard superseded by this standard is as follow: GB/T 18487.2-2001 Electric Vehicle Conductive Charging System Part 2: EMC Requirements for Off-board Electric Vehicle Supply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. 2 Normative References The following documents for the application of this document are essential.
