Electrically propelled road vehicles — Functional and safety requirements for power transfer between vehicle and external electric circuit — Part 5: Automatic conductive power transfer

This document defines requirements for the onboard system (vehicle side) related to the automatic connection for conductive alternating current (AC) and/or direct current (DC) power transfer between electrically propelled road vehicles (EVs) and external electric circuits. This document addresses the following aspects: — electrical and mechanical safety requirements; — compatibility requirements; — environmental conditions; — functionality requirements; — test procedures. This document applies to: — EVs supporting automatic connection of a vehicle inlet according to IEC 62196-2, IEC 62196-3, IEC TS 62196-3-1 or IEC TS 63379 (category 1) and — EVs supporting automatic connection of a category 3 vehicle inlet or category 3 plug (typically at the underbody of the vehicle) according to IEC TS 61851-26. NOTE 1 IEC TS 61851-26 does not include automatic connection of vehicle inlets or plugs of category 1 and category 2, that can also be mounted at the underbody of the vehicle. Requirements for EVs equipped with an ACD or ACD counterpart of category 2 are specified in EN 50696 and IEC 63407. Requirements for simultaneous operation of multiple power transfer interfaces are under consideration and not covered in this document. NOTE 2 Requirements for ACD infrastructure, communication sequence and communication interface are specified in IEC 61851-23-1, IEC TS 61851-26 and IEC TS 61851-27. NOTE 3 EMC requirements for vehicles conductively connected to the supply network are defined in IEC 61851-21-1.
