ISO 5474-2:2024

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.
