IEC 61851-21-2:2018 defines the EMC requirements for any off-board components or equipment of such systems used to supply or charge electric vehicles with electric power by conductive power transfer (CPT), with a rated input voltage, according to IEC 60038:2009, up to 1 000 VC or 1 500 V DC and an output voltage up to 1 000 V C or 1 500 V DC.This document covers off-board charging equipment for mode 1, mode 2, mode 3 and mode 4 charging as defined in IEC 61851-1:2017.This first edition, together with IEC 61851-21-1, cancels and replaces IEC 61851-21:2001. It constitutes a technical revision.This edition includes the following significant technical changes with respect to IECA 61851-21:2001:a) this document addresses now only EMC related tests instead of other electrical tests;b) Clauses 2 and 3 have been updated;c) the port definition, the test-setups and their corresponding limits as well as the operation modes are defined more precisely;d) Annexes A to F have been added.
