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 socket-outlets 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.
