This document specifies the EV supply equipment of system A, system B and system C as defined in Annex AA, Annex BB and Annex CC. Other systems are under consideration.
This document provides the requirements for bidirectional power transfer (BPT) EV supply equipment for system A, with a rated maximum voltage at side A up to 1 000 V AC or 1 500 V DC. The requirements for reverse power transfer (RPT) and BPT for system B and system C are under consideration and are not specified in this document.
This second edition cancels and replaces the first edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) the structure has been rearranged according to IEC 61851-1:2017;
b) electrical safety requirements in Clause 8 and Clause 12 have been revised based on the requirements in IEC 62477-1 and inspired by the hazard based safety approach of IEC 62368-1;
c) test methods for checking conformity to the stated requirements have been mostly added; general provisions for compliance tests have been specified in Clause 102;
d) specific requirements and/or information for the following functions have been added: energy transfer with thermal management system (101.2), bi-directional power transfer control (Annex DD), multi- side B separated EV supply equipment (Annex FF), and communication and energy transfer process (Annex GG);
e) Annex AA (system A), Annex BB (system B) and Annex CC (system C) have been updated including additions in conjunction with b) and c). This document has been limited to be applicable to system A, system B and system C;
f) the former Annex DD and Annex EE have been deleted. A new Annex EE, with the requirements for the artificial test load, has been added.
g) a new informative annex for the touch current and the touch impulse current (Annex HH) has been added
This part of IEC 61851 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 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 EV supply equipment of system A, system B and system C as defined in Annex AA, Annex BB and Annex CC. Other systems are under consideration.
This document provides the requirements for bidirectional power transfer (BPT) EV supply equipment for system A, with a rated maximum voltage at side A up to 1 000 V AC or 1 500 V DC. The requirements for reverse power transfer (RPT) and BPT for system B and system C are under consideration and are not specified in this document.
Annex DD provides information about BPT.
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.
The requirements for digital communication between EV supply equipment and the EV to control energy transfer are defined in IEC 61851-24.
Requirements for energy transfer with an automated connection device are given in IEC 61851-23-1 .
Specific requirements for EV supply equipment with multiple vehicle connectors are provided in Annex FF.
General information about energy transfer control, signalling and digital communication is provided in Annex GG.
General information on the touch current and touch impulse current is provided in Annex HH.
Requirements for EV supply equipment without current, voltage and/or power control 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.
Requirements for such use case are under consideration.
NOTE Requirements for EVs mated to an EV supply equipment are specified in ISO 17409:2020. ISO 17409 will be revised to the ISO 5474 series .
