IEC TS 61851-26:2026 PDF

IEC TS 61851-26:2026, in combination with IEC 61851-1 or IEC 61851-23, gives the requirements for EV supply equipment with automatic docking and undocking functions (aEVSE) at the underbody of 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 or a single socket-outlet. Requirements for aEVSE with more than one vehicle connector or more than one socket-outlet are under consideration. This document only applies to automatic couplers of category 3, located at the underbody of an electric vehicle. This document does not apply to automatic coupler of category 1: using a vehicle coupler defined by IEC 62196-2, IEC 62196-3 or IEC TS 62196-3-1. This document does not apply to automatic couplers of category 2: using an electro-mechanical interface defined by EN 50696. EN 50696 also specifies automatic couplers located at the underbody of an electric vehicle. However, these couplers only provide DC power transfer. 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.
