RS ISO 5474-3: 2024
Electrically propelled road vehicles — Functional and safety requirements for power transfer between vehicle and external electric circuit — Part 3: DC power transfer

Abstract

This document in combination with ISO 5474-1 specifies requirements for conductive power transfer
using direct current (DC) with a voltage up to 1 500 V d.c. between electrically propelled road vehicles and
external electric circuits.
This document provides requirements for conductive charging in mode 4 according to IEC 61851-1. For
mode 4, this document provides requirements regarding the power transfer only with isolated DC EV supply
equipment according to IEC 61851-23.
The requirements in this document are applicable to vehicle power supply circuits.
An outlook of requirements for megawatt charging applications is given in Annex B.
This document does not provide:
— requirements for simultaneous operation of multiple power transfer interfaces 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.
