BS IEC 62765-2-2019 PDF

Full title and description

STB BS IEC 62765-2-2019 — "Surface transport — Railway applications — Power supply and earthing for charging of electric vehicles — Part 2: Interfaces between the vehicle and the fixed infrastructure (based on IEC 62765-2:2018)". This standard specifies requirements for electrical interfaces, safety measures and earthing arrangements applicable to the charging of electric road vehicles by railway or tramway fixed infrastructure and for related conductive connection systems.

Abstract

This standard defines the electrical interface characteristics, protective measures and earthing arrangements for conductive charging systems where surface transport fixed infrastructure provides electrical energy to charge on-board energy storage systems. It covers connection interfaces between the vehicle and fixed infrastructure, including requirements for safe connection, disconnection, earthing, protective bonding and compatibility to reduce risk of electric shock and ensure interoperability.

Scope

This part of IEC 62765 applies to conductive interfaces between surface transport fixed infrastructure (for example, tramway or railway charging points integrated into stops, depots or wayside equipment) and electric vehicles using on-board rechargeable energy storage systems. It specifies requirements for electrical connection, protective equipotential bonding, earthing arrangements, switching and disconnection, as well as measures to reduce risk during mechanical coupling and charging operations. It does not cover wireless/power‑transfer systems, traction power supply for vehicle propulsion, nor in‑vehicle charging equipment beyond the immediate interface.

Key topics and requirements

• Definition of the electrical interface characteristics for conductive charging between vehicle and fixed infrastructure.
• Requirements for earthing and protective bonding to prevent electric shock and ensure safety during connection and in-service conditions.
• Specifications for switching, isolation and interlocking to ensure safe make/break operations and prevent energization when not intended.
• Compatibility and interoperability guidance for connector types and mechanical arrangements at the vehicle/infrastructure interface.
• Measures for insulation, clearances, creepage distances and protection against overcurrent and fault conditions.
• Operational and maintenance considerations, including marking, documentation and verification tests for interface equipment.

Typical use and users

Engineers and designers of surface-transport charging infrastructure, rolling stock electrical system designers, railway and tramway operators, safety assessors, installers and maintenance teams, and regulatory authorities use this standard to ensure safe, interoperable conductive charging interfaces. It is used when specifying, procuring or certifying fixed charging installations and the vehicle-side connections for depot charging, wayside charging and station-based charging for trams and light rail vehicles.

Related standards

Related documents include the other parts of IEC 62765 series, general vehicle charging standards and railway electrical safety standards addressing earthing, bonding and protection, as well as connector and charging interface standards for electric vehicles. Standards addressing traction supply systems, wireless charging, and national electrical safety regulations are also commonly referenced alongside this part.
