IEC 62196-1:2025

Overview

IEC 62196-1:2025 - Part 1 of the IEC 62196 series - defines general requirements for plugs, socket‑outlets, vehicle connectors and vehicle inlets used for conductive charging of electric vehicles (EVs). This fifth edition replaces the 2022 edition and covers accessories and cable assemblies that incorporate control means with rated operating voltages and currents not exceeding:

• 690 V AC (50–60 Hz) at up to 250 A; and
• 1 500 V DC at up to 800 A.

Significant updates in this edition include new tests for latching devices and retaining means and the inclusion of type 4 accessories.

Key Topics and Technical Requirements

IEC 62196-1:2025 sets out comprehensive requirements that manufacturers, test labs and designers rely on:

• Ratings and preferred operating ranges (voltage, current, signal/control circuits)
• Interfaces and classification of accessories by purpose, electrical operation, locking/interlock facilities and shutters
• Mechanical and electrical construction: terminals, strain relief, cable glands and overall assembly
• Protection against electric shock and contact sequencing (order of contact insertion/withdrawal)
• Insulation resistance, dielectric strength and breaking capacity
• Thermal performance (temperature rise, thermal cycling) and contact endurance
• Mechanical strength tests: drop, impact, flexing, vehicle drive-over and misalignment tests
• Environmental durability: humidity exposure, corrosion resistance, resistance to heat and fire
• Electromagnetic compatibility (EMC), conditional short‑circuit current requirements and marking/labeling
• New test coverage for latching/retaining devices and requirements for type 4 accessories
• Annexes include standard test gauge sheets and guidance for accessories connected directly to printed circuit boards (PCBs)

Practical Applications - Who Uses This Standard

IEC 62196-1:2025 is essential for:

• EV charging hardware manufacturers producing plugs, sockets, vehicle connectors, inlets and cable assemblies
• Charging station designers and system integrators ensuring safe, interoperable conductive charging interfaces
• Test laboratories and certification bodies conducting conformity and type testing
• Regulators, procurement teams and fleet operators specifying product compliance and safety
• Electrical and product design engineers responsible for connector mechanical/electrical compliance

Using this standard supports product safety, interoperability and regulatory compliance in EV infrastructure and helps reduce field failures and safety risks associated with conductive charging.
