Overview

EN ISO 4165:2003 is an international standard that defines the dimensions and electrical characteristics of the double-pole connection used in road vehicles. This standard ensures the interchangeability of electrical connections designed to supply additional appliances in vehicles operating at nominal supply voltages of 12 V or 24 V direct current (d.c.). Developed by ISO/TC 22 Technical Committee on Road Vehicles and adopted by CEN, this standard applies primarily to connections in protected areas such as passenger compartments and luggage spaces.

By adhering to EN ISO 4165:2003, manufacturers and vehicle operators can ensure consistent performance, safety, and compatibility of electrical connectors used for auxiliary power in road vehicles, supporting various onboard electrical appliances and devices.

Key Topics

  • Standardized Dimensions
    Specifies precise physical dimensions for plugs and sockets to guarantee mechanical compatibility and reliable connection performance.

  • Electrical Characteristics

    • Nominal voltages supported: 12 V and 24 V d.c.
    • Maximum connection force: 50 N
    • Connection and disconnection force range: 16 N to 50 N
    • Voltage drop limits: Maximum 50 mV after repeated use
    • Temperature rise during operation: Maximum 16 K after 1 hour at 12 A current
  • Application Scope
    Designed for use within vehicle compartments or luggage areas, requiring additional protection when mounted externally.

  • Performance and Durability Tests
    Includes test procedures and requirements for:

    • Connection and disconnection forces
    • Temperature rise under continuous current load
    • Voltage drop measurement for electrical efficiency
    • Withstand voltage test ensuring safety under elevated voltages
    • Temperature and humidity cycling to verify environmental resistance
    • Durability through repeated insertion and withdrawal cycles (1,000 cycles)
  • Compliance with Related Standards
    References ISO 6722 for cable specifications and ISO 8092-2 for general performance requirements and test methods, ensuring harmonious integration within vehicle electrical systems.

Applications

EN ISO 4165:2003 is widely used in the automotive industry for supplying power to additional electrical devices and accessories that require reliable electrical connections within road vehicles. Typical applications include:

  • Supplying power to aftermarket or factory-installed appliances such as portable refrigerators, battery chargers, and communication devices.
  • Ensuring standardized electrical connections for camper vans, recreational vehicles (RVs), and commercial trucks operating on 12 V or 24 V systems.
  • Facilitating quick connection and disconnection of auxiliary electrical equipment within protected areas of the vehicle.
  • Providing a robust interface in onboard electrical wiring harnesses used for vehicle accessories and add-ons.

This standard supports road vehicle manufacturers, component suppliers, and aftermarket accessory producers by defining a common, reliable interface for electrical appliance power supply, enhancing interoperability and safety.

Related Standards

  • ISO 6722 – Road vehicles - Single-core cables up to 600 V: Defines cable dimensions, test methods, and requirements relevant to cables used with connectors defined in ISO 4165.
  • ISO 8092-2 – Road vehicles - Electrical connections - Part 2: Provides general definitions, test procedures, and performance criteria that complement the requirements in EN ISO 4165.
  • EN 24165:1991 – Previous European standard replaced by EN ISO 4165:2003, reflecting updated technical requirements.

Adherence to EN ISO 4165:2003 ensures compatibility with these standards for comprehensive quality and safety management within road vehicle electrical systems.


By implementing the specifications of EN ISO 4165:2003, automotive and electrical manufacturers can achieve consistent, safe, and reliable electrical connections for double-pole systems used in auxiliary supply applications across a range of 12 V and 24 V road vehicle platforms. This promotes harmonization, better product compatibility, and elevated user safety standards in the automotive electrical domain.
