Overview
The IEC 62196-2:2016 standard specifies dimensional compatibility and interchangeability requirements for plugs, socket-outlets, vehicle connectors, and vehicle inlets used in conductive charging of electric vehicles (EVs). Designed by the International Electrotechnical Commission (IEC), this edition focuses on a.c. (alternating current) pin and contact-tube accessories with nominal operating voltages up to 480 V a.c. and rated currents up to 63 A three-phase or 70 A single-phase.
This second edition revises and replaces the 2011 standard, reflecting updated specifications particularly for configuration types 2 and 3, including the introduction of an optional shutter for configuration type 2 connectors. It is intended for use with IEC 62196-1:2014, which covers general requirements.
Key Topics
-
Dimensional Compatibility: Defines precise measurements to ensure accessories-such as plugs and connectors-are physically compatible for reliable and safe connection in EV charging systems.
-
Interchangeability: Guarantees that components from different manufacturers conforming to this standard will fit and function together, supporting widespread infrastructure interoperability.
-
Rated Electrical Parameters:
- Maximum voltage: 480 V a.c.
- Rated current: up to 63 A for three-phase or 70 A for single-phase setups
- Frequency range: 50 Hz to 60 Hz
-
Configurations:
- Types 1, 2, and 3 connector interfaces with dedicated standard sheets
- Updates primarily focus on types 2 and 3, including the safety-feature option of shutters for type 2 plugs
-
Safety and Protection:
- Requirements for protection against electric shock
- Specifications for earthing provisions and protective earthing conductor size/color
- Mechanical durability and resistance to aging, heat, fire, corrosion, and environmental factors
-
Test and Performance Criteria:
- Insulation resistance and dielectric strength tests
- Breaking capacity and short-circuit current withstand testing
- Temperature rise under normal operation
- Electromagnetic compatibility (EMC) considerations
-
Marking and Identification: Standardized labeling of components to ensure traceability and correct usage.
Applications
IEC 62196-2:2016 plays a crucial role in the development and deployment of electric vehicle charging infrastructure by:
- Enabling manufacturers to produce interoperable charging accessories, which helps expand user options and charging station compatibility.
- Supporting automotive OEMs and charging station providers by specifying common mechanical and electrical interfaces.
- Enhancing consumer safety and charging reliability, through uniform safety requirements like shutters and standardized protective earthing.
- Facilitating mass-market adoption of EVs by ensuring standardized conductive charging interfaces that meet international safety and performance expectations.
- Integrating with other parts of the IEC 62196 series to provide a comprehensive framework covering all aspects of EV conductive charging.
