Description
of content: BOS 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
