Overview

SIST EN IEC 62196-3:2023 (identical to IEC 62196-3:2022) specifies dimensional compatibility requirements for vehicle couplers with pins and contact tubes used in conductive charging of electric vehicles. It covers high-power DC interfaces and combined AC/DC interfaces intended for conductive charging systems that include control means, with rated voltage and current as defined in IEC 62196-1:2022. The standard applies to vehicle couplers used in charging mode 4 (IEC 61851‑1:2017, Clause 6.2.4, case C) and to circuits referenced in IEC 61851-1 and IEC 61851-23, for ambient temperatures from -30 °C to +40 °C (note: -35 °C for SE). Only cables with copper or copper-alloy conductors are covered.

Key Topics and Requirements

• Dimensional compatibility: standardized geometries and layout for pins, contact tubes and mating interfaces to ensure mechanical fit and safe connection between vehicle inlets and connectors.
• Scope of interfaces: high-power DC vehicle connectors and combined AC/DC couplers intended for mode 4 charging and for circuits covered by IEC 61851 series.
• Reference ratings: electrical ratings (voltage/current) follow IEC 62196‑1:2022; the document increases ratings compared with the previous edition and updates test requirements.
• Safety and performance clauses: marking, protection against electric shock, earthing provisions, insulation, breaking capacity, temperature rise, mechanical strength, contact endurance, EMC and environmental exposure (humidity, thermal cycling, corrosion).
• Operational limits: ambient temperature range and requirement for copper/copper-alloy conductors are explicitly stated.
• Conformance and test guidance: harmonized with EN adoption and references to tests and normative documents across the IEC/EN ecosystem.

Practical Applications

• Ensures interoperable, safe physical interfaces for EV manufacturers, charging station (EVSE) designers, and connector suppliers working on DC fast-charging and combined AC/DC systems.
• Used by component designers to produce vehicle inlets and couplers that mate reliably with standardized plugs and contact tubes.
• Guides testing laboratories, certification bodies, and OEM quality teams when validating dimensional, mechanical and electrical compliance for high-power EV charging hardware.
• Valuable for infrastructure planners and fleet operators specifying chargers and vehicles to ensure mechanical compatibility and safe, repeatable connections.

Who Should Use This Standard

• Electric vehicle OEMs and suppliers

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.

The basic portion of the combined vehicle inlet can be used with a basic connector for either
AC charging or with a combined vehicle connector for DC charging.
Combined couplers shall only be used for DC charging with the "DC EV supply equipment of
System C" described in IEC 61851-23:—, Annex CC.
NOTE 1 Implementation of all aspects (i.e., topology and communication) according to IEC 61851-23:—, Annex CC
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.
