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.
