ISO 5474:2024

Description

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.
