IEC 62196-2:2016

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.
