Abstract

IEC TS 61851-27:2026, in combination with IEC 61851-1 or IEC 61851-23, gives the requirements for EV supply equipment with automatic docking and undocking functions (aEVSE) of a vehicle coupler according to IEC 62196-2, IEC 62196-3 or IEC TS 62196-3-1 for power transfer with electrically propelled road vehicles according to ISO TS 5474-5.Use of aEVSE with the megawatt charging system is under consideration.This document provides requirements for aEVSE with a single vehicle connector.Requirements for aEVSE with more than one vehicle connector are under consideration.This document only applies to aEVSE with automatic couplers of category 1: using vehicle couplers defined by IEC 62196-2, IEC 62196-3 or IEC TS 62196-3-1.This document only specifies automatic conductive energy transfer using a vehicle connector and a vehicle inlet; it does not specify automatic conductive power transfer using a plug and a socket-outlet.This document does not apply to aEVSE with automatic couplers of category 2: using an electro-mechanical interface defined by EN 50696.This document does not apply to aEVSE with automatic coupler of category 3 (see IEC TS 61851-26).EMC requirements for EV supply equipment are defined in IEC 61851-21-2.Interoperable communication for docking and undocking between an aEVSE and an EV, extending the communication between an EV supply equipment and an EV as specified in IEC 61851-1, IEC 61851-23, IEC 61851-24 and the ISO 15118 series, is under consideration.This document does not cover all safety aspects related to maintenance
