SIST EN IEC 62196-3:2026 is the SIST adoption of IEC 62196-3:2026. It specifies dimensional compatibility requirements for DC and AC/DC pin and contact-tube vehicle couplers used in electric vehicle conductive charging systems with control means, so manufacturers, charging-system engineers and test laboratories can design, match and verify the same vehicle-side interface.
What does SIST EN IEC 62196-3:2026 specify?
SIST EN IEC 62196-3:2026 covers vehicle couplers with standardized pins and contact tubes for conductive charging of electric vehicles. It focuses on high power DC interfaces and combined AC/DC interfaces, and it is organized as a main body of clauses 1 to 37, standard sheets for several configurations, and annexes for gauges, PCB-related accessories, thermal-management applications and latching examples.
| Annex | What it covers |
|---|---|
| AAA | Standard sheets for test gauges in 14.1.9 |
| BBB | EV accessories directly connected to printed circuit boards (PCBs) |
| CCC | Vehicle connector, vehicle inlet and cable assembly for DC charging intended to be used with a thermal management system |
| DDD | Interlock function - example of retaining means and latching device |
The main clauses cover scope, references, terms, ratings, connection between the power supply and the electric vehicle, classification, marking, dimensions, safety, earthing, terminals, interlocks, construction, degrees of protection, insulation, breaking capacity, normal operation, temperature rise, cables, mechanical strength, creepage distances, heat and fire, corrosion, short-circuit current, EMC, vehicle drive-over, thermal cycling, humidity exposure, misalignment and contact endurance. The standard sheets then define the detailed geometry for configurations AA, BB, EE, FF and GG.
What are the key requirements of SIST EN IEC 62196-3:2026?
Interface definition and dimensional compatibility
SIST EN IEC 62196-3:2026 defines the DC interface and the combined AC/DC interface in Clause 6. The DC interface may use a single physical contact arrangement with power and signal contacts, while the combined interface carries AC or DC energy through separate power contacts. In practice, this means the mating parts are not free-form - the interface type, contact functions and configuration have to match the standard sheets.
Clause 7 classifies the accessories by purpose, interface and standard-sheet configuration. The document identifies vehicle connectors and vehicle inlets, and it distinguishes the configurations used for DC and combined AC/DC applications. For a buyer or design team, this is the clause that tells you which family of product you are specifying.
Clause 9 and Table 303 tie each configuration to the relevant standard sheets. The vehicle connector and vehicle inlet have to comply with the matching configuration, so the drawings, tooling and inspection gauges all come from the same geometry set.
Electrical safety, contact sequence and earthing
Clause 10.3 fixes the order of contact engagement for DC interfaces. Protective earth comes first, then the DC power contacts, then the isolation monitor contacts, and then the control pilot contact, with the proximity detection or connection switch contact placed in the specified sequence. In practice, this prevents the power contacts from closing before the protective connection is made.
Clause 11.301 covers the DC portion of the protective earthing conductor. The conductor size is based on the I t methodology or the earthing requirements cited in the document, and the conductor has to be identified by the green-and-yellow colour combination. This is the part that drives cable design, conductor selection and harness marking.
Clause 12 applies earthing provisions to non-isolated systems and not to isolated systems. Clause 14 and Annex DDD cover interlocks and latching, so the accessory has to hold the latched position and support the prescribed interlock behaviour before charging can proceed.
Thermal-management applications and testing
Annex CCC adds the version of the standard for DC charging accessories and cable assemblies intended for a thermal management system. It distinguishes between thermal sensing only and thermal transport with thermal sensing, and it requires manufacturer data sheets, installation instructions and intervention values for the thermal sensing device.
Annex CCC also changes how testing is handled. It groups the tests into sequences and uses defined reference devices and test setups for temperature rise, thermal sensing, vehicle driveover, humidity-related checks and coolant-related tests. For a test house, this annex is the practical guide for how to set up the sample, what to mate it with, and which configuration-specific figures to use.
Liquid coolants receive separate controls in Annex CCC. The coolant has to be environmentally acceptable, compatible with the materials, suitable for the flash point requirement, and safe under overpressure conditions. In practice, coolant choice and documentation become part of the technical file, not just a design detail.
Durability and configuration-specific checks
Clauses 34 to 37 cover thermal cycling, humidity exposure, misalignment and contact endurance. These checks matter because the coupler has to remain usable after environmental stress, repeated mating and imperfect alignment. Annex CCC also uses these clauses selectively for the thermal-management variants.
The document also links certain configuration-specific requirements to the standard sheets. Configuration AA, BB, EE, FF and GG each have dedicated geometry and functional information, so the correct configuration has to be chosen before testing or production release.
What terms does SIST EN IEC 62196-3:2026 define?
- Vehicle coupler - A standardized mating set with pins and contact tubes used on the vehicle side of conductive charging.
- Combined interface - An interface that includes both AC and DC portions with separate power contacts.
- DC interface - The interface used for DC charging, with power and signal contacts arranged by configuration.
- Control Pilot (CP) - The control contact used in the sequencing and signalling between the vehicle and the supply equipment.
- Protective earth (PE) - The earthing connection that must be made before the DC power contacts in the prescribed sequence.
- Proximity detection or connection switch (PP or CS) - The contact used to detect connection or insertion state during mating and withdrawal.
- Thermal sensing - A function that measures DC contact temperature and sends the temperature information to the DC EV supply equipment or the EV.
- Reference device (RD) - The mating test accessory used to create the required test condition in Annex CCC.
Who uses SIST EN IEC 62196-3:2026?
SIST EN IEC 62196-3:2026 is used by manufacturers of vehicle connectors, vehicle inlets and cable assemblies when they design the mating geometry and choose the contact arrangement. It is also used by EV and charging-system engineers who need to match the vehicle side to the DC EV supply equipment architecture.
Test laboratories and certification bodies use it to build test setups, choose reference devices and check dimensional compatibility, interlocks, temperature rise and thermal sensing performance. Quality managers, compliance teams and buyers use it to confirm that a product family matches the right configuration and that the supplied documentation supports the intended charging application.
It is relevant to the electric road vehicle sector, including DC charging equipment and combined AC/DC charging interfaces. The document is especially useful where thermal management, cable assemblies and high-current vehicle-side couplers are part of the design.
What changed in SIST EN IEC 62196-3:2026 from the previous edition?
SIST EN IEC 62196-3:2026 replaces the second edition published in 2022. The edition is described as a technical revision.
The changes stated in the document are:
- content from IEC TS 62196-3-1 is integrated into a normative annex for thermal-management applications
- ratings are increased for all configurations
- references are added to the new tests in IEC 62196-1:2025, Clauses 34, 35, 36 and 37

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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 62196-3 has been prepared by IEC subcommittee 23H: Plugs, socket-outlets, and couplers
for industrial and similar applications, and for electric vehicles, of IEC technical committee 23:
Electrical accessories. It is an International Standard.
This third edition cancels and replaces the second edition published in 2022. This edition
