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 62196-3 has been prepared by subcommittee 23H: Plugs, socket-

outlets and couplers foe industrial and similar applications, and for electric vehicles, of IEC

technical committee 23: Electrical accessories.
The text of this standard is based on the following documents:
FDIS Report on voting

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all the parts in the IEC 62196 series, under the general title Plugs, socket-outlets,

vehicle connectors and vehicle inlets – Conductive charging of electric vehicles, can be found

on the IEC website.

This part of IEC 62196 is to be read in conjunction with IEC 62196-1. The clauses of the

particular requirements in Part 3 supplement or modify the corresponding clauses in Part 1.

Where the text indicates an "addition" to or a "replacement" of the relevant requirement, test

specification or explanation of Part 1, these changes are made to the relevant text of Part 1,

which then becomes part of the standard.

Subclauses, figures, tables or notes which are additional to those in IEC 62196-1 are

numbered starting from 301.
In this standard, the following print types are used:
– requirements proper: in roman type;
– test specifications: in italic type;
– notes: in smaller roman type.

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,

INTRODUCTION

Responding to global challenges of CO reduction and energy security, the automobile

industries have been accelerating the development and commercialization of electric vehicles

and hybrid electric vehicles.

In addition to the prevailing hybrid electric vehicles, battery electric vehicles including plug-in

hybrid electric vehicles are going to be mass-marketed.

To support the diffusion of such vehicles, this standard provides the standard interface

configurations of vehicle couplers to be used in conductive charging of electric vehicles,

taking the most frequent charging situations into consideration.
IEC 62196 is divided into several parts as follows:
– Part 1: General requirements, comprising clauses of a general character.

– Part 2: Dimensional compatibility and interchangeability requirements for a.c. pin and

contact-tube accessories.

– Part 3: Dimensional compatibility and interchangeability requirements for d.c. and a.c./d.c.

pin and contact-tube vehicle couplers.

Part 3: Dimensional compatibility and interchangeability requirements
for d.c. and a.c./d.c. pin and contact-tube vehicle couplers
1 Scope

This part of IEC 62196 is applicable to vehicle couplers with pins and contact-tubes of

standardized configuration, herein also referred to as “accessories”, intended for use in

electric vehicle conductive charging systems which incorporate control means, with rated

operating voltage up to 1 500 V d.c. and rated current up to 250 A, and 1 000 V a.c. and rated

current up to 250 A.

This part of IEC 62196 applies to high power d.c. interfaces and combined a.c./d.c. interfaces

of vehicle couplers specified in IEC 62196-1:2014, and intended for use in conductive

charging systems for circuits specified in IEC 61851-1:2010, and IEC 61851-23:2014.

The d.c. vehicle connectors covered by this part of the standard are used only in charging

mode 4, according to Case C in Clause 6.2 of IEC 61851-1:2010, Figure 3 in Clause 6.3.1 of

IEC 61851-1:2010 and IEC 62196-2:2011.

The d.c. vehicle inlets covered by this part of the standard are used only in charging mode 4,

according to Case C in Clause 6.2 of IEC 61851-1:2010, Figure 3 in Clause 6.3.1 of

IEC 61851-1:2010.

These vehicle couplers are intended to be used for circuits similar to those specified in

IEC 61851-23 which operate at different voltages and which may include ELV and
communication signals.

This part of IEC 62196 applies to the vehicle couplers to be used in an ambient temperature

of between –30 °C and +50 °C.
NOTE 1 In some countries, other requirements may apply.
NOTE 2 In the following country, –35 °C applies: SE.

IEC 61851-23:2014, Annex AA “D.C. electric vehicle charging station of System A” or Annex

BB “D.C. Electric vehicle charging station of System B” respectively. See the corresponding

standard sheets for additional interface details.

Additional subclause:
6.301 Configuration EE and FF combined interface

A combined interface extends the use of a basic interface for a.c. and d.c charging. D.C.

charging can be achieved by providing additional d.c. power contacts to supply d.c. energy to

the electric vehicle.

The basic portion of the combined vehicle inlet can be used with a basic connector for a.c.

charging only or a combined vehicle connector for d.c. charging.

Combined couplers shall only be used for d.c. charging with the “d.c. electric vehicle charging

station of System C” described in IEC 61851-23:2014, Annex CC.

General requirements and ratings for all contacts are given in IEC 62196-1:2014, Table 5.

If the a.c. or d.c ratings of a mating connector and inlet differ, the coupler (mating pair) shall

be used at the lower rating of either the vehicle connector or vehicle inlet of the mating

accessory.

Ratings and requirements for the use of the combined interface with a.c. are defined in

IEC 62196-2:2011.

Electric vehicles with a combined vehicle inlet shall withstand a.c. voltage at the power

contacts of the basic portion.

NOTE This requirement will be withdrawn when an equivalent update is included in ISO 17409.
