IEC 61851-23:2023
(Main)Electric vehicle conductive charging system - Part 23: DC electric vehicle supply equipment
Electric vehicle conductive charging system - Part 23: DC electric vehicle supply equipment
IEC 61851-23:2023 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.
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
Système de charge par conduction pour véhicule électrique – Partie 23: Système d'alimentation en courant continu pour véhicules électriques
Etablit des exigences relatives aux connexions brasées pour montage en surface. Les exigences se rapportent aux ensembles intégrant uniquement le montage en surface ou aux portions d'ensembles pour montage en surface incluant d'autres technologies associées (par exemple montage par trous traversants, montage à puce, à borne, etc.).
