Standard history

This part of IEC 61851-3 series (in a first step as Technical Specification for three-year period) together with part 1 of IEC 61851-3, applies to communication for the conductive transfer of electric power between the supply network and a light electric road vehicle or a removable RESS or traction-battery of a light electric road vehicle, with a rated supply voltage up to 480 V a.c. or up to 400 V d.c. and a rated ìoutputî voltage up to 480 V a.c. or up to 200 V d.c.. Energy management system for control of power transfer between battery systems and voltage converter units specifies the communication for all devices that may take part in energy management control. The basic application profile for energy management systems consists of the following parts: Part 3-4: General definitions for communication; Part 3-5: Pre-defined communication parameters and general application objects; Part 3-6: Voltage converter unit communication; Part 3-7: Battery system communication.
