Scope

This part of IEC 61851-3 series (in a first step as Technical Specification for three-year period) together with part 1 of IEC 61851, applies to the equipment for the conductive transfer of electric power between the supply network and an electric road vehicle when connected to the supply network, supply voltage up to 480 V a.c. or up to 400 V d.c. and a rated output voltage up to 480 V a.c. or up to 200 V d.c..The supply systems described in the IEC 61851-3 series are primarily intended for the use by electric road vehicles of category L hereinafter referred to as light electric vehicles (light Evs).
NOTE 1 Light EV includes all electrically propelled two and three wheeled vehicles of Category L1 up to Category L7 according to the definition of ECE-TRANS-WP29-78r2e and all electrically propelled or assisted cycles.Light electric road vehicles (light EVs) imply all road vehicles, including plug-in hybrid road vehicles (PHEV), that derive all or part of their energy from on-board rechargeable energy storage systems, (RESS), including traction batteries.The electrical protection of the complete light EV supply system from the connection to the supply network up to the light EV or removed RESS complies with protective separation between mains and d.c. and with galvanic separation between mains and d.c. or class III.Supplementary requirements for output voltages over 60 V d.c. are given in this document.Supplementary requirements for Class III equipment with output voltages over 15 V d.c. and over 6 V a.c. are given in this document.Requirements for bidirectional energy transfer d.c. to a.c. are under consideration and are not part of this edition.
NOTE 2 This standard is not mandatory for proprietary EV supply system configurations Type B or D according to IEC 61851-3 series provided they have equivalent or higher safety levels.
