RS ISO 5474-2: 2024
Electrically propelled road vehicles — Functional and safety requirements for power transfer between vehicle and external electric circuit — Part 2: AC power transfer

Abstract

This document in combination with ISO 5474-1 specifies requirements for conductive power transfer using
alternating current (AC) with a voltage up to 1 000 V a.c. between electrically-propelled road vehicles and
external electric circuits.
NOTE External electric circuits are not part of the vehicle.
This document provides requirements for conductive charging in modes 2, 3 according to IEC 61851-1 and
reverse power transfer.
This document applies to vehicle power supply circuits. Examples of circuit diagrams for different
configurations of chargers on-board electric vehicles are shown in Annex A.
This document also provides requirements for reverse power transfer through on-board standard socketoutlets
and/or a EV plug or vehicle inlet according to IEC 62196-1 or IEC 62196-2 conductively connected to
the vehicle power supply circuit. Requirements for AC power transfer using a charger without at least simple
separation are under consideration.
This document does not provide:
— requirements for simultaneous operation of multiple EV plugs or vehicle inlets and
— requirements for power transfer while driving (electric road systems)
but they are under consideration.
This document does not provide:
— requirements for mopeds and motorcycles (which are specified in ISO 18246);
— comprehensive safety information for manufacturing, maintenance and repair personnel;
— requirements for vehicle to load adapters.
