DIN IEC/TS 61851-27:2025-09 - Draft

This document 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. This document provides requirements for aEVSE with a single vehicle connector. 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 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). 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. 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. Use of aEVSE with the megawatt charging system is under consideration. Requirements for aEVSE with more than one vehicle connector are under consideration. 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.
