FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organisation for standardisation comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardisation in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. 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 nongovernmental organisations liasing with
the IEC also participate in this preparation. The IEC collaborates closely with the International Organisation for
Standardisation (ISO) in accordance with conditions determined by agreement between the two organisations.
2) The formal decisions or agreements of the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62196-1 has been prepared by IEC subcommittee 23H: Industrial
plugs and socket-outlets, of IEC technical committee 23: Electrical accessories.

INTRODUCTION
IEC 61851-1 specifies electric vehicle conductive charging equipment. This International
Standard, referred to as the IEC 60309 series in IEC 61851-1, specifies the requirements for
plugs, socket-outlets, connectors, inlets and cable assemblies as described in IEC 61851-1.
Some charging can be achieved by direct connection from an electric vehicle to common
mains socket outlets. Some modes of charging require a dedicated supply and charging
equipment incorporating control and communication circuits. This standard covers the
mechanical, electrical and performance requirements for dedicated plugs, socket outlets,
vehicle connectors and vehicle inlets for interfacing between such dedicated charging
equipment and the electric vehicle.
This International Standard may be published in several parts, as necessary, including this
Part 1, comprising clauses of a general character, and subsequent parts, presenting particular
requirements for individual types.

1 Scope
This part of IEC 62196 is applicable to plugs, socket-outlets, connectors, inlets and cable
assemblies for electric vehicles, intended for use in conductive charging systems which
incorporate control means, with a rated operating voltage not exceeding:
– 690 V a.c., 50 – 60 Hz, at a rated current not exceeding 250 A;
– 600 V d.c., at a rated current not exceeding 400 A.
These accessories and cable assemblies are intended to be used for circuits specified in
IEC 61851-1 which operate at different voltages and frequencies and which may include ELV
and communication signals.
These accessories and cable assemblies are to be used in an ambient temperature of
between –30 °C and +50 °C. In some countries, other requirements may apply.
These accessories are intended to be connected only to cables with copper or copper-alloy
conductors.
The accessories covered by this standard are for use in certain modes of charging EV’s.
These modes are defined in IEC 61851-1. These definitions and a description of the types of
connection (cases A, B and C), also described in IEC 61851-1, are reproduced herein as
Annex A.
Table 1 illustrates the types of accessories (B, U , U , U ) permitted for each charging
32 A D
situation (mode and case) and identifies where it is mandatory to use the accessories covered
by this standard. These are indicated by the entries in the columns headed “62196” in
Table 1.
The table also describes situations in which either an accessory covered by this standard, or
other standardized accessories, are permitted to be used. They are identified by an entry in
the column headed “62196” and the word “Any” under the column headed “Type”.
This standard does not apply to those standardised accessories used in charging systems
where the use of such accessories constructed to the requirements of other standards is
permitted (e.g. in mode 1 and mode 2). Such standardized accessories may be used for those
situations (mode and case) identified in Table 1 by the word “Any” under the column headed
“Type” and with no corresponding entry under the column headed “62196”.
This standard can be used as a guide for accessories with a lesser number of contacts and
lower ratings for use with light duty vehicles.

4.1 General requirements
Accessories shall be so designed and constructed that in normal use their performance is
reliable and minimises the risk of danger to the user or surroundings.
Compliance is checked by meeting all of the relevant requirements and tests specified.
4.2 General notes on tests
4.2.1 Tests according to this standard are type tests. If a part of an accessory has previously
passed tests for a given degree of severity, the relevant type tests shall not be repeated if the
severity is not greater.
4.2.2 Unless otherwise specified, the samples are tested as delivered and under normal
conditions of use, at an ambient temperature of (20 ± 5) °C; the tests are made at rated
frequency.
4.2.3 Unless otherwise specified, the tests are carried out in the order of the clauses of this
standard.
4.2.4 Three samples are subjected to all the tests, except if necessary for the test of Clause
30, one new additional sample is tested. If, however, the tests of Clauses 21, 22 and 23 have
to be made with both d.c. and a.c., the tests with a.c. in Clauses 21, 22 and 23 are made on
three additional samples. For the tests of Clauses 21.3 and 33, three new samples are to be
used.
– 14 – 62196-1  IEC:2003(E)
4.2.5 Accessories are deemed to comply with this standard if no sample fails in the complete
series of appropriate tests. If one sample fails in a test, that test and those preceding which
may have influenced the test result are repeated on another set of three samples, all of which
shall then pass the repeated tests.
NOTE In general, it will only be necessary to repeat the test which caused the failure, unless the sample fails in
one of the tests of Clauses 22 and 23, in which case the tests are repeated from that of Clause 21 onwards.
The applicant may submit, together with the first set of samples, the additional set which may be wanted should
one sample fail. The testing station, without further request, will then test the additional samples and will reject
only if a further failure occurs. If the additional set of samples is not submitted at the same time, the failure of one
sample will entail a rejection.
4.2.6 When the tests are carried out with conductors, they shall be copper and comply with
IEC 60227, IEC 60228 [Clause 2, solid (class 1), stranded (class 2), flexible (class 5 and 6)],
and IEC 60245-4 as accessories according to this standard are intended to be connected to
