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 The previous edition of this standard superseded by this standard is as follow: GB/T 18487.2-2001 Electric Vehicle Conductive Charging System Part 2: EMC Requirements for Off-board Electric Vehicle Supply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.

所有试验应使用由制造商提供的典型的供电设备和通信电缆（在CPT端口）。若供电设备未提供电缆，试验应在电缆的典型长度下进行。 附录A给出了非车载直流供电设备在CPT端口进行传导骚扰测量的试验布置示例。具体的试验布置参考GB 4824-2013和GB/T6113.201。 充电模式2的缆上控制与保护盒（不含电缆）及装置（IC-CPD），应按照台式设备布置进行测试。 5　供电设备的试验负载条件 5.1　概述 具有通信功能（在供电设备和车辆之间）的供电设备的通信线应按附录C进行端接，通信信号必须由各自的模拟器提供并经由适合的耦合装置馈入。 若供电设备具有大量类似端口或连接器的端口，则应选择足够数量的端口来模拟实际运行状况，并确保覆盖了所有不同类型的终端，如所有端口数量的20%或至少四个端口。 注：需注意的是，这并不总是代表实际使用，因为当电池逐渐充满时功率将下降。 5.2　电动汽车的CPT供电设备 供电设备的CPT端口应连接到AE，该AE包括由AN和/或ISN所形成的车辆模拟器，并与可调电阻负载相连。 6　测试过程中的操作条件 6.1　概述 试验在本部分规定的模式下进行。试验应在第5章规定的负载条件下进行。 试验计划中应规定EUT的配置和运行模式，且试验报告中应准确记录试验时的实际条件。 应对以下两种运行模式进行评估：  待机模式：模拟供电设备正常供电，其车辆插头插入车辆插座，此时供电设备处于未充电状态（例如，当车辆电池已充满电或等待电网决定何时充电）；  充电模式：试验过程中，供电设备的输出电流处于产生最高发射情况的功率。 注：当没有负载连接时无需进行评估，在待机模式中已充分考虑。 若供电设备和车辆之间（如：充电控制）使用非控制导引方式或其他信号（例如PLC）方式的通信，则试验应在最恶劣的信号情况下进行，如选择制造商规定的最大通信速率的信号。 试验应在供电设备规定的工作范围和额定输入电压下实施，除非相关基础标准另有规定。 缆上控制与保护装置（IC-CPD）应按照充电模式3进行试验。 6.2　试验说明 供电设备应同时符合本部分规定的抗扰度和发射要求。 本部分涉及的供电设备要求是基于逐个端口给出的。表1~表4规定了抗扰度要求。本部分中的表5~表13规定了发射要求。 本部分规定的所有测试项目可按照任何顺序进行试验。 试验应调节阻性负载，使得供电设备在额定输出电压情况下，发射测量在功率分别为额定功率的20%，50%和80%状态下进行。抗扰度测量在额定功率的50%下进行。 所有类型端口都应按本部分要求进行抗扰度测试。 试验仪器、试验方法和试验布置见表1~表6。 6.3　环境条件/限制 本部分已考虑了在正常的EMC环境中的所有供电设备。供电设备可在多种场所安装使用。本部分覆盖所有安装于室内或室外的供电设备，安装使用环境包括住宅、商业、轻工业环境（以下统称非工业环境）（见GB/T 17799.1和 GB 17799.3）和工业环境（见GB/T 17799.2和 GB 17799.4）。当供电设备制造商未规定供电设备的预期使用的环境时，应实施最严格的发射和抗扰度试验，即采用最低的发射限值和最高的抗扰度试验等级。 7　抗扰度要求 7.1　性能判据 7.1.1　概述 供电设备应维持在一种安全状态，作为本部分中规定的试验实施结果。进一步指导信息见标准 GB/T 18487.1。 基于供电设备的充电模式有不同的性能判据，尤其是对于充电模式3和充电模式4。 在交流或直流电源输入端口上实施浪涌（GB/T 17626.5）和电快速瞬变/脉冲群（GB/T 17626.4）时，应使用合适的仪器进行测量，该仪器可测量直流输出端口上相关的瞬态幅值。这种测量应按照附录E所描述的布置进行。应满足附录E的要求。 当受试设备有计量和计费功能时，相应的性能判据应按照适用的产品标准进行定义，例如GB/T 17215.321。 供电设备制造商应提供EMC试验过程中或试验后的功能描述和性能判据定义。 7.1.2　性能判据A 试验实施的过程中或试验后，供电设备应在供电设备制造商所定义的容许范围内，按照预期继续运行。其运行状态不允许改变（即充电模式下继续保持充电，待机模式下保持闲置状态）。 注：对于充电模式2和充电模式3，状态的改变包括PWM信号的变化，对于充电模式4，状态的改变包括充电电流的任意变化（超过制造商定义的容许范围）。 7.1.3　性能判据B 试验完成后，供电设备应在供电设备制造商所定义的容许范围内，按照预期继续运行。此外，在试验实施过程中，应保持供电设备的主要功能（在供电设备制造商所定义的容许范围内）。次要功能（包括显示等）在试验过程中允许性能降级，但应在试验后恢复到初始状态。 试验实施后，供电设备应不改变其运行状态（即充电模式下继续保持充电，待机模式下保持闲置状态）。 注1：对于充电模式2和充电模式3，状态的改变包括PWM信号的变化，对于充电模式4，状态的改变包括充电电流的任意变化（超过制造商定义的容许范围）。 注2：对于电压暂降和短时中断抗扰度测试，如果进行了充电流程中规定的人工操作，如刷卡或者充电启动等，可视为符合性能判据B。 7.1.4　性能判据C 试验实施的过程中和试验后，供电设备变化到故障保护状态。如已符合GB/T18487.1中定义的安全要求，这种状态需要用户干预以重启充电或自动恢复充电。 7.2　试验要求 根据供电设备类型和其预期使用的环境，测试要求见表1~4。 所有缆上控制与保护装置应满足表1。 当供电设备制造商限制了产品使用场所，抗扰度要求见表2。 后续表中所有提及的“信号/控制端口”均指供电设备的电源输入侧的端口。供电设备电源输出和负载侧无浪涌抗扰度要求，除非制造商说明书中规定的典型充电电缆超过30 m。 直流供电设备的浪涌和电快速瞬变脉冲群的试验布置见附录E。
