Overview
IEC 62196-2:2025 specifies dimensional compatibility requirements for AC pin and contact‑tube accessories used in conductive charging of electric vehicles (EVs). It applies to EV plugs, EV socket‑outlets, vehicle connectors and vehicle inlets with standardized pin/contact‑tube configurations, rated up to 480 V AC (50–60 Hz) and currents not exceeding 63 A three‑phase or 70 A single‑phase. This fourth edition (2025) cancels and replaces the 2022 edition and includes a technical revision with new latching‑device tests and corrections to standard sheets.
Key topics and technical requirements
- Dimensional compatibility: Standard sheets define geometry and tolerances for four configuration types (standard sheets for each configuration are included).
- Ratings and interfaces: Nominal voltage and current limits, interface definitions (basic/combined/DC interfaces are covered in the series).
- Mechanical and electrical construction: Requirements for terminals, connections, earthing, insulation, dielectric strength, breaking capacity and temperature rise.
- Interlocks and latching devices: New tests for latching devices and interlock sequences to verify latched/unlatched positions and retention behavior.
- Tests and endurance: Contact endurance, mechanical strength, thermal cycling, humidity exposure, corrosion resistance, vehicle drive‑over and misalignment tolerance.
- Safety provisions: Protection against electric shock, creepage/clearance, fire resistance and EMC considerations.
- Standard sheets and test gauges: Normative sheets and annexes provide test gauge definitions and coordinate/package spaces for automated docking and undocking (useful for robotic coupling).
- Marking and classification: Rules for marking, classification by electrical operation and interface type.
Practical applications
- Ensure interoperability between EVs and charging equipment by using standardized pin/contact dimensions.
- Provide prescriptive design criteria for connector and inlet manufacturers to meet mechanical and electrical compatibility.
- Support type‑approval and conformity testing performed by laboratories and certification bodies (including latching/interlock tests added in this edition).
- Inform procurement and installation specifications for charging station OEMs, fleet operators and EV manufacturers.
- Facilitate design of automated docking systems via coordinate and package‑space guidance in annexes.
Who should use this standard
- EV connector and inlet designers and manufacturers
- Charging station and socket‑outlet OEMs
- Test laboratories and certification bodies
- Automotive OEMs and EV system integrators
- Regulators, procurement teams and standards committees
