IEC 62196-3:2022 Overview

The IEC 62196-3:2022 standard, published by the International Electrotechnical Commission (IEC), specifies dimensional compatibility requirements for DC and AC/DC pin and contact-tube vehicle couplers used in conductive charging of electric vehicles (EVs). This second edition supersedes the 2014 version, introducing technical revisions including increased electrical ratings and updated testing methods aligned with IEC 62196-1:2022.

The standard applies to vehicle couplers, incorporating pins and contact tubes of standardized configurations-referred to as “accessories”-designed for conductive charging systems with rated voltage and current aligned to IEC 62196-1:2022. It covers plugs, socket-outlets, vehicle connectors, and inlets to ensure reliable and safe connections between EVs and charging infrastructure.

Key Topics

• Dimensional Compatibility: Defines precise physical dimensions and tolerances for pins and contact tubes to ensure interchangeability and proper fit.
• Electrical Ratings: Updates ratings for voltage and current to accommodate advancements in electric vehicle charging technology.
• Control and Safety Features: Includes requirements for control means embedded in connectors to prevent electric shock and ensure operational safety.
• Material and Durability: Standards for rubber and thermoplastic materials used in connectors to resist aging, heat, fire, corrosion, and mechanical stresses.
• Interlocks and Protection: Specifications for interlocking mechanisms and protective measures to avoid accidental disconnection or exposure to live parts.
• Testing Procedures: Integration of updated testing criteria for thermal cycling, humidity exposure, misalignment, contact endurance, and other reliability assessments as specified in IEC 62196-1 (Clauses 34 to 37).
• Connector Classifications and Markings: Definitions for accessory classifications with detailed marking requirements to support identification and compliance.
• Compliance and Safety: Guidelines to enhance compatibility, safety, and functionality in EV conductive charging interfaces worldwide.

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.

vehicle inlets and cable assemblies as described in IEC 61851 (all parts).
Charging using off-board DC charging equipment can be achieved by the direct connection of
an electric vehicle to DC EV supply equipment incorporating control and communication circuits.
To support the connection of DC power for such vehicles, this document provides the standard
interface configurations of DC vehicle couplers and accessories 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 requirements for AC pin and contact-tube accessories.
– Part 3: Dimensional compatibility requirements for DC and AC/DC pin and contact-tube
vehicle couplers.
– Part 3-1: Vehicle connector, vehicle inlet and cable assembly intended to be used with a

ensures that:
This system allows DC charging but prevents AC and DC charging at the same time.
– AC chargeable EVs with a basic vehicle inlet do not need any means to protect themselves against DC voltage
at the inlet. This protection is provided by the DC charging system.
– Vehicle protection against mischarging in case of fault is provided in accordance with ISO 17409:2020.
NOTE 2 If the AC or DC ratings of a mating connector and inlet differ, the coupler (mating pair) is used at the lower
rating of either the vehicle connector or vehicle inlet of the mating accessory.

25 Flexible cables and their connection
Clause 25 of IEC 62196-1:2022 applies except as follows:
Additional subclause:
25.301 Additional test for strain relief
Accessories shall be submitted to the additional following test:
Non-rewirable accessories are tested as delivered.
Rewirable accessories are tested with the maximum and minimum size cables recommended
by the manufacturer.
– 16 – IEC 62196-3:2022 © IEC 2022
Conductors of the cable of rewirable accessories are introduced into the terminals, the terminal
screws being tightened just sufficiently to prevent the conductors from easily changing their
position.
The cable anchorage is used in the normal way, clamping screws being tightened with a torque
equal to two-thirds of that specified in IEC 62196-1:2022, 27.1. After reassembly of the sample,
with cable glands, if any, in position, the component parts shall fit snugly, and it shall not be
possible to push the cable into the sample to any appreciable extent.
The sample is fixed in the test apparatus so that the axis of the cable is vertical where it enters
the sample.
The cable is then subjected once to a pull of 750 N. The pull is applied without jerks for a
duration of 1 min.
Immediately afterwards, the cable is subjected to a torque, of the value specified in
IEC 62196-1:2022, Table 11, for 1 min.
During the tests, the cable shall not be damaged.
After the tests, the cable shall not have been displaced by more than the values indicated in
IEC 62196-1:2022, Table 11. For rewirable accessories, the ends of the conductors shall not
have moved noticeably in the terminals; for non-rewirable accessories, there shall be no break
in the electrical connections.
For the measurement of the longitudinal displacement, a mark is made on the cable at a
distance of approximately 2 cm from the end of the sample or the cable anchorage before
starting the tests. If, for non-rewirable accessories, there is no definite end to the sample, an
additional mark is made on the body of the sample.
After the tests, the displacement of the mark on the cable in relation to the sample or the cable
anchorage is measured.
