IEC 61851-21-1:20 17(E)与IEC 61851-1:20 10一起给出了电动车辆(EV)与AC或DC电源的导电连接的要求。它仅适用于在整车上测试或在充电系统组件级别（ESA-电子子组件）上测试的车载充电单元。 本文件涵盖了连接到主电源时任何充电模式下的电力推进车辆的电磁兼容性（EMC）要求。第一版与IEC 61851-21-2一起取消并取代了IEC 61851-21:20 01。它构成技术修订。本版本包括以下与IEC 61851相关的重大技术变更？21:2001: a)本文件现在仅涉及EMC测试，而不涉及其他电气测试； b)更精确地定义测试设置； c)增加了附件A“人工网络、非对称人工网络和将充电站集成到测试设置中”。

IEC 61851-21-1:2017(E), together with IEC 61851-1:2010, gives requirements for conductive connection of an electric vehicle (EV) to an AC or DC supply. It applies only to on-board charging units either tested on the complete vehicle or tested on the charging system component level (ESA - electronic sub assembly).
This document covers the electromagnetic compatibility (EMC) requirements for electrically propelled vehicles in any charging mode while connected to the mains supply. This first edition, together with IEC 61851-21-2, cancels and replaces IEC 61851-21:2001. It constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 61851？21:2001:
a)   this document addresses now only EMC tests instead of other electrical tests;
b)   test setups are defined more precisely;
c)   Annex A "Artificial networks, asymmetric artificial networks and integration of charging stations into the test setup" was added.
