Plugs, socket-outlets, vehicle connectors and vehicle inlets - Conductive charging of electric vehicles - Part 3-1: Vehicle connector, vehicle inlet and cable assembly for DC charging intended to be used with a thermal management system

IEC TS 62196-3-1:2020(E) applies to accessories and cable assemblies with the same configuration as specified in IEC 62196-3:2014 with rated operating voltage not exceeding 1 500 V DC and a rated current not exceeding 500 A that employ
- thermal sensing, or
- thermal transport and thermal sensing with the system architecture described in 4.101.
These accessories and cable assemblies are intended to be used in conductive charging systems for circuits specified in IEC 61851-23.
NOTE Edition 2 of IEC 61851-23 is under development.
The accessories covered by this document are intended to be used in charging mode 4 according to IEC 61851-1. These accessories are intended to be connected to cables according to the IEC 62893 series for DC cables.
