电动汽车传导充电系统 第26部分：配备位于电动汽车底部对接器的电动汽车供电设备

[中文适用范围]： IEC TS 61851-26:2026 结合 IEC 61851-1 或 IEC 61851-23，规定了根据 ISO TS 5474-5 标准，在电动道路车辆底部安装的具有自动对接和分离功能的电动汽车供电设备（aEVSE）的要求。兆瓦充电系统的应用正在考虑之中。本文件适用于具有单个车辆连接器或单个插座的 aEVSE，而多个车辆连接器或多个插座的 aEVSE 要求仍在考虑之中。本文件仅适用于位于电动汽车底部的类别 3 自动连接器。本文件不适用于类别 1 自动连接器：采用 IEC 62196-2、IEC 62196-3 或 IEC TS 62196-3-1 定义的车辆连接器。本文件也不适用于类别 2 自动连接器：采用 EN 50696 定义的机电接口。EN 50696 还规定了位于电动汽车底部的自动连接器，但这些连接器仅提供直流电传输。aEVSE 与电动汽车之间对接和分离的可互操作通信，扩展 IEC 61851-1、IEC 61851-23、IEC 61851-24 和 ISO 15118 系列中规定的电动汽车供电设备与电动汽车之间的通信，也正在考虑之中。本文件不涵盖与维护相关的所有安全方面。 [外文原描述]： 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.
