ELECTRIC VEHICLE CONDUCTIVE CHARGING SYSTEM –
Part 24: Digital communication between a d.c. EV charging
station and an electric vehicle for control of d.c. charging
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61851-24 has been prepared by IEC technical committee 69:
Electric road vehicles and electric industrial trucks.
The text of this standard is based on the following documents:
FDIS
69/273FDIS
Report on voting
69/280/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

market, responding
Concurrently, the development of charging infrastructure for electric vehicles has also been
expanding. As supplementary system of a.c. charging system, d.c. charging is recognized as
an effective solution to extend the available range of electric vehicles, and different d.c.
charging systems are being used over the world. The international standardization in terms of
charging infrastructure including d.c. charging systems is indispensable for the diffusion of
electric vehicles, and this standard is developed for the manufacturers’ convenience by
providing general specifications for control communication protocols between off-board d.c.
charger and electric vehicles.

ELECTRIC VEHICLE CONDUCTIVE CHARGING SYSTEM –
Part 24: Digital communication between a d.c. EV charging
station and an electric vehicle for control of d.c. charging
1 Scope
This part of IEC 61851, together with IEC 61851-23, applies to digital communication between
a d.c. EV charging station and an electric road vehicle (EV) for control of d.c. charging, with
an a.c. or d.c. input voltage up to 1 000 V a.c. and up to 1 500 V d.c. for the conductive
charging procedure.
The EV charging mode is mode 4, according to IEC 61851-23. The charging station supplied
by high voltage a.c. supply is not covered by this standard.
Annexes A, B, and C give descriptions of digital communications for control of d.c. charging
specific to d.c. EV charging systems A, B and C as defined in Part 23.
