Full title and description

ISO/TS 5474-5:2024 — Electrically propelled road vehicles — Functional and safety requirements for power transfer between vehicle and external electric circuit — Part 5: Automatic conductive power transfer. This Technical Specification defines vehicle-side requirements for automatic conductive connection systems that enable AC and/or DC power transfer between electrically propelled road vehicles (EVs) and external electric circuits, covering safety, compatibility, environmental and functional aspects plus test procedures.

Abstract

This document specifies requirements for the onboard (vehicle) system related to automatic connection for conductive alternating current (AC) and/or direct current (DC) power transfer between electrically propelled road vehicles and external electric circuits. It addresses electrical and mechanical safety, compatibility, environmental conditions, functional behaviour and test procedures. It applies to EVs that support automatic connection using vehicle inlets or plugs referenced in IEC/EN/ISO technical documents (for example IEC 62196 series and IEC TS 61851-26) and notes interfaces and topics that are covered by other standards.

Scope

ISO/TS 5474-5:2024 applies to vehicle-side equipment that supports automatic conductive power transfer for EVs. It covers safety (electrical and mechanical), compatibility with vehicle inlets/plugs and external equipment, environmental requirements (operating conditions, ingress protection, temperature), functionality (connection/disconnection behaviour, interlocks, status indication) and test methods to verify compliance. The document applies to automatic connection arrangements referenced to IEC vehicle inlet/plug categories and excludes detailed requirements for ACD infrastructure, some EMC matters and simultaneous operation of multiple interfaces, which are addressed elsewhere.

Key topics and requirements

• Electrical safety requirements for automatic conductive connections (clearances, protection against electric shock, earth/PE considerations).
• Mechanical safety and robustness of automatic coupling systems (mechanical strength, retention, grounding, locking and release mechanisms).
• Compatibility requirements with standardized vehicle inlets/plugs and categories (references to IEC 62196 series, IEC TS 61851-26, IEC TS 62196-3-1, IEC TS 63379, etc.).
• Environmental and climatic requirements (operating temperature ranges, vibration, ingress protection and corrosion resistance).
• Functional requirements for connection, disconnection and fault handling (interlocks, sequencing, status signalling and safe interruption of power).
• Test procedures and verification methods to demonstrate conformity (electrical, mechanical, environmental and functional tests).
• Limitations and normative cross-references: this TS does not cover infrastructure-side ACD details, multi-interface simultaneous operation, or some EMC and communication specifics (covered in IEC/EN documents).

Typical use and users

Primary users include EV manufacturers (OEMs), charging system designers and suppliers, vehicle electrical-system engineers, component manufacturers (inlets, couplers, actuators), test laboratories, conformity assessment bodies and regulators. The standard is used for product design, supplier specifications, type testing and integration of automatic conductive charging systems on passenger cars, light commercial vehicles and heavy vehicles that implement underbody or other automated conductive connections.

Related standards

Key related documents and standards commonly referenced alongside ISO/TS 5474-5 include IEC 62196-2 / IEC 62196-3 and related IEC TS documents for connector/inlet definitions, IEC TS 61851-26 and IEC TS 61851-27 for automated connection of underbody couplers, IEC 61851-21-1 for EMC aspects, EN 50696 and IEC 63407 for certain ACD categories, and ISO 5474 series parts (Part 1 general requirements, Part 2 AC, Part 4 wireless magnetic-field WPT, etc.).
