This part of IEC 61851, defines the EMC requirements for off board components or equipment of systems used to supply or charge electric vehicles with electric power by conductive power transfer (CPT), with a rated input voltage, according to IEC 60038, up to 1000 V a.c. or 1500 V d.c. and an output voltage up to 1000 V a.c. or 1500 V d.c This standard covers off board charging equipment for mode 1, mode 2, mode 3 and mode 4 charging as defined in IEC 61851-1. Cables where there is no electronics or no electric/electronic switching are considered as passive (benign) and are deemed to comply with the emission and immunity requirements of this standard without any need for testing. This standard does not apply to any on-board components or equipment of charging or power supply systems for electric vehicles. The EMC requirements for such equipment are covered by IEC 61851-21-1. Compliance with the emission and immunity requirements of this standard is verified where it can be demonstrated that the EUT meets the respective limits, during type tests in the measuring arrangement of this standard. Requirements for electric vehicle wireless power transfer (WPT) systems are covered in IEC 61980 series of standards. Note 1: For components and subassemblies covered by other product standards regarding EMC these requirements should be considered.
