[中文适用范围]： 本文件规定了采用自动连接装置（ACD）的直流电动汽车充电设备的通用要求，该设备通过导电方式与车辆连接，其中A侧额定最大电压不超过1 000 V交流电或1 500 V直流电，B侧额定最大电压不超过1 500 V直流电。本文件所涵盖的直流电动汽车充电设备基于以下两种系统：一是IEC 61851-23:2023附件BB中所述的B系统；二是该标准附件CC中所述的C系统。关于反向功率传输（RPT）和双向功率传输（BPT）的要求尚在研究之中，未在本文件中规定。直流电动汽车充电设备的电磁兼容（EMC）要求见IEC 61851-21-2:2018。本文件规定了直流电动汽车充电设备与电动汽车之间控制通信的通用要求；而用于控制直流能量传输的数字通信要求则分别由ISO 15118-20:2022和IEC 61851-24:2023界定。本文件仅适用于第2类自动耦合器，即采用机电接口的耦合器，具体为符合IEC 63407的自动化充电系统用自动耦合器。本文件不适用于IEC TS 61851-27中定义的第1类自动耦合器，亦不适用于IEC TS 61851-26中定义的第3类自动耦合器。本文件未涵盖与设备维护相关的所有安全方面。关于在A侧与B侧之间不提供简单隔离或保护隔离的系统的要求尚在研究中。关于不具备电流、电压或功率控制功能的充电设备的要求亦在研究中。符合本文件规定的充电设备，不得用于通过以下方式向单个电动汽车传输电能：（a）同一充电设备配备多个同类型车辆连接器；或（b）多个充电设备共同供电。 [外文原描述]： IEC 61851-23-1:2026 provides the requirements for DC EV supply equipment with an automated connection device (ACD) for conductive connection to the vehicle, with a rated maximum voltage at side A of up to 1 000 V AC or up to 1 500 V DC and a rated maximum voltage at side B up to 1 500 V DC. This document specifies the DC EV supply equipment with an automated connection device based on – system B described in IEC 61851-23:2023, Annex BB, and – system C described in IEC 61851-23:2023, Annex CC. The requirements for reverse power transfer (RPT) and bidirectional power transfer (BPT) are under consideration and are not specified in this document. EMC requirements for DC EV supply equipment are defined in IEC 61851-21-2:2018. This document provides the general requirements for the control communication between a DC EV supply equipment and an EV. The requirements for digital communication between DC EV supply equipment and electric vehicle for control of DC energy transfer are defined in ISO 15118-20:2022 and IEC 61851-24:2023. This document only applies to automatic couplers of category 2, i.e. using an electro-mechanical interface: automatic coupler for an automated charging system according to IEC 63407. This document does not apply to automatic coupler of category 1 as described in IEC TS 61851-27 . This document does not apply to automatic coupler of category 3 as described in IEC TS 61851-26 . This document does not cover all safety aspects related to maintenance. Requirements for systems not providing simple separation or protective separation between side A and side B are under consideration. Requirements for EV supply equipment without control of current, voltage or power are under consideration. EV supply equipment in compliance with this document are not intended to provide energy transfer to a single EV with – multiple vehicle connectors of the same EV supply equipment, or – multiple EV supply equipment.
