Electric vehicle conductive charging system - Part 21-2: Electric vehicle requirements for conductive connection to an AC/DC supply - EMC requirements for off board electric vehicle charging systems

2Scope / Description

IEC 61851-1:2017 specifies the electromagnetic compatibility (EMC) requirements for all external (vehicle-side) components or equipment used in electric vehicle charging systems that employ conductive power transfer (CPT). These systems operate at input voltages up to 1,000 V AC or 1,500 V DC, and output voltages up to 1,000 V AC or 1,500 V DC, in accordance with IEC 60038:2009. This document covers external charging equipment corresponding to Charging Modes 1, 2, 3, and 4 as defined in IEC 61851-1:2017. Cables without electronic or electrical/electronic switching circuits are considered passive (benign) and shall meet the emission and immunity requirements of this document without undergoing any testing. This document does not apply to components or equipment of charging or power systems installed within vehicles. EMC requirements for such equipment are specified in IEC 61851-21-1:2017. Compliance with the emission and immunity requirements of this document is evaluated by demonstrating that the Equipment Under Test (EUT) meets the applicable limit values during the type testing procedures defined in this document. Requirements for wireless power transfer (WPT) systems in electric vehicles are addressed in IEC 61980 (all parts).
