Electric vehicle conductive charging system - Part 1: General requirements
IEC 61851-1:2010 applies to on-board and off-board equipment for charging electric road vehicles at standard a.c. supply voltages (as per IEC 60038) up to 1 000 V and at d.c. voltages up to 1 500 V, and for providing electrical power for any additional services on the vehicle if required when connected to the supply network. It includes characteristics and operating conditions of the supply device and the connection to the vehicle; operators and third party electrical safety, and the characteristics to be complied with by the vehicle with respect to the a.c./d.c. EVSE, only when the EV is earthed. This second edition cancels and replaces the first edition published in 2001. It constitutes a technical revision. The main changes with respect to the first edition of this standard are:
- revision of connector definitions and current levels (Clause 8);
- modification definition of pilot wire to pilot function;
- division of Clause 9 to create Clauses 9 and 11;
- Clause 9: specific requirements for inlet, plug and socket-outlet;
- Clause 11: EVSE requirements: the basic generic requirements for charging stations;
- renumbering of annexes;
- deletion of previous Annex A and integration of charging cable requirements into new Clause 10;
- Annex B becomes Annex A and is normative for all systems using a PWM pilot function with a pilot wire; Annex C becomes Annex B;
- replacement of previous Annex D (coding tables for power indicator) with B.4 in Annex B using new values;
- new informative Annex C describing an alternative pilot function system.
This publication is of high relevance for Smart Grid.

ELECTRIC VEHICLE CONDUCTIVE CHARGING SYSTEM –
Part 1: General requirements
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 61851-1 has been prepared by IEC technical committee 69:
Electric road vehicles and electric industrial trucks.
This second edition cancels and replaces the first edition published in 2001. It constitutes a
technical revision.
The main changes with respect to the first edition of this standard are the following:
– revision of connector definitions and current levels (Clause 8);
– modification definition of pilot wire to pilot function;
– division of Clause 9 to create Clauses 9 and 11;
– Clause 9: specific requirements for inlet, plug and socket–outlet;
– Clause 11: EVSE requirements: the basic generic requirements for charging stations;
– renumbering of annexes;
---------------------- Page: 7 ----------------------
– 6 – 61851-1 Ó IEC:2010
– deletion of previous Annex A and integration of charging cable requirements into new
Clause 10;
– Annex B becomes Annex A and is normative for all systems using a PWM pilot function
with a pilot wire;
– Annex C becomes Annex B;
– replacement of previous Annex D (coding tables for power indicator) with B.4 in Annex B
using new values;
– new informative Annex C describing an alternative pilot function system.
The text of this standard is based on the following documents:
FDIS Report on voting
69/173/FDIS 69/179/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.
A list of all parts of the IEC 61851 series, under the general title: Electric vehicle conductive
charging system can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
reconfirmed,
withdrawn,
replaced by a revised edition, or
amended.
IMPORTANT – The “colour inside” logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct understanding
of its contents. Users should therefore print this publication using a colour printer.

ELECTRIC VEHICLE CONDUCTIVE CHARGING SYSTEM –
Part 1: General requirements
1 Scope
This part of IEC 61851 applies to on-board and off-board equipment for charging electric road
vehicles at standard a.c. supply voltages (as per IEC 60038) up to 1 000 V and at d.c.
voltages up to 1 500 V, and for providing electrical power for any additional services on the
vehicle if required when connected to the supply network.
Electric road vehicles (EV) implies all road vehicles, including plug in hybrid road vehicles
(PHEV), that derive all or part of their energy from on-board batteries.
The aspects covered include characteristics and operating conditions of the supply device
and the connection to the vehicle; operators and third party electrical safety, and the
characteristics to be complied with by the vehicle with respect to the a.c./d.c. EVSE, only
when the EV is earthed.
NOTE 1 Class II vehicles are not defined, but the lack of information for this type of vehicle means that the
requirements for the standard are under consideration.
NOTE 2 This standard also applies to EVSE with on-site storage capability.
Requirements for specific inlet, connector, plug and socket-outlets for EVs are contained in
IEC 62196-1:2003. Standard sheets for the vehicle connector and inlet are also under
consideration. They will be incorporated in a separate part of standard IEC 62196.
This standard does not cover all safety aspects related to maintenance.
This standard is not applicable to trolley buses, rail vehicles, industrial trucks and vehicles
designed primarily for use off-road.
