IEEE 3381-2025

This guide applies to electric vehicle supply equipment (EVSE) with a rated supply voltage up to 1000 V alternating current (ac) or up to 1500 V direct current (dc) and a rated output voltage up to 1500 V dc. This guide specifies a method of condition evaluation of EVSE, including general principles, condition evaluation method, and classification.

This guide provides basic equipment condition evaluation methods for EVSE manufacturers and charging facility operators to track EVSE operating status and provide early warning of equipment failures for targeted maintenance, helping to ensure the safe and stable operation of the charging stations and power grids.
