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.
BSI recommends this version of standard for organisations operating in or with the UK. The ISO edition is available here if required.
