Full title and description

St IEC 62196-1-2025 — Plugs, socket‑outlets, vehicle connectors and vehicle inlets — Conductive charging of electric vehicles — Part 1: General requirements. This edition (5th) sets general safety, construction and test requirements for EV conductive charging accessories and cable assemblies rated up to 690 V AC (≤250 A) and up to 1 500 V DC (≤800 A).

Abstract

This 2025 technical revision of IEC 62196‑1 updates general requirements for plugs, socket‑outlets, vehicle connectors and vehicle inlets used for conductive EV charging. Significant changes include addition of tests for latching and retaining means and the formal inclusion of "type 4" accessories, together with harmonized electrical and mechanical test methods appropriate for higher DC currents and modern connector designs. The revision replaces the previous (2022) edition.

Scope

The standard applies to EV plugs, EV socket‑outlets, vehicle connectors and vehicle inlets (collectively "accessories") and to cable assemblies intended for use in conductive charging systems that include control means. Rated operating limits covered include alternating current systems up to 690 V AC at up to 250 A and direct current systems up to 1 500 V DC at up to 800 A. The document establishes general requirements, tests and marking for safe interconnection and operation in conductive EV charging installations.

Key topics and requirements

• Electrical ratings and dielectric, insulation and temperature-rise tests for AC and DC charging accessories.
• Mechanical strength, endurance and contact retention tests for plugs, inlets and cable assemblies.
• New and updated tests for latching devices and retaining means to ensure secure mating under expected service conditions.
• Inclusion and definition of "type 4" accessories and associated requirements for interoperability and safety.
• Requirements for markings, identification, IP/ingress protection guidance and information supplied by the manufacturer.
• Guidance on compatibility with other parts of the IEC 62196 series and relevant EV charging system control means.
