<p>Electric vehicle conductive charging system - Part 23-1: DC electric vehicle supply equipment - Automated connection device</p>

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 sy
