Replacement:

This part of the IEC 61851 series, together with [IEC 61851-1 Ed. 3] and [IEC 61851-23, Ed. 2.0], applies to the EV supply equipment to provide energy transfer between the supply network and electric vehicles (EVs), with a rated maximum voltage at side A (supply network side) up to 1 000 V AC or up to 1 500 V DC and a rated maximum voltage at side B (EV side) up to 1 250 V DC.

NOTE 1 A rated maximum voltage of the EV supply equipment at side B of 1 500 V DC is under consideration.

This document specifies the EV supply equipment of Megawatt Charging System (MCS) equipped with a coupler according to IEC TS 63379. Systems different to system MCS using a coupler specified in IEC TS 63379 are under consideration.

Requirements for bidirectional power flow systems are under consideration.

This document does not cover all safety aspects related to maintenance.

Requirements for systems not providing protective separation between side A (supply network side) and side B (EV side) are under consideration.

The requirements for digital communication between the EV supply equipment and the EV for control of energy transfer are defined in ISO 15118-10[1] and ISO 15118-20.

The specific requirements for EV supply equipment with multiple side Bs (EV sides) are provided in Annex FF.

General information of communication and the energy transfer process is described in Annex GG.

General information on the touch current and touch impulse current is provided in Annex HH.

EV supply equipment in compliance with this document is not intended to provide energy transfer to a single EV using:

multiple vehicle connectors of the same EV supply equipment; or

multiple EV supply equipments.

Requirements for such use case are not specified in this document, but are under consideration.

NOTE 2  The safety requirements of vehicle during charging are specified in ISO 5474 series.

NOTE 3  Requirements for an optional automated connection of system MCS are under preparation in IEC 61851-27.

Requirements for EVs mated to an EV supply equipment according to this document are specified in ISO 5474-3:2023, Annex B.
