Full title and description

Safety requirements for secondary batteries and battery installations — Part 6: Safe operation of lithium‑ion batteries in traction applications (IEC 62485-6:2021). This part specifies safety measures and operational requirements for lithium‑ion battery installations used in electric off‑road and traction applications (for example: industrial trucks, cleaning machines, automated guided vehicles, electrically propelled lifting platforms, and electric‑propelled boats and ships).

Abstract

IEC 62485-6:2021 provides guidance and requirements to ensure the safe operation, charging, monitoring, handling, maintenance and emergency response for lithium‑ion battery installations in traction applications. It addresses installation environment, ventilation, thermal management, battery management systems, marking and information for safe use, risk assessment and operational procedures. A corrigendum (Corr.1) correcting editorial and technical points was published in February 2023 and is included in current consolidated copies.

Scope

Applies to battery installations used for electric off‑road vehicles and traction equipment but does not cover the design of the vehicles themselves. Typical covered applications include lift trucks, tow trucks, automated guided vehicles, cleaning machines, electrically propelled lifting platforms, and small electric watercraft. The standard focuses on safe operation, charging and maintenance of lithium‑ion traction batteries in those installations.

Key topics and requirements

• Operational safety requirements for charging, discharging and stand‑by conditions
• Battery management system (BMS) functions and monitoring requirements
• Thermal management, ventilation and prevention of thermal runaway propagation
• Requirements for installation layout, spacing, compartments and protective enclosures
• Fire mitigation, emergency procedures and incident response planning
• Information, marking, signage and documentation for safe use and maintenance
• Inspection, maintenance schedules, handling and storage precautions
• Risk assessment and measures to limit hazards to persons and property
• Requirements for charging equipment, isolation and electrical protection

Typical use and users

Used by battery and vehicle manufacturers, system integrators, facility engineers, safety and maintenance personnel, standards and compliance officers, testing laboratories and regulatory authorities to specify, operate and audit safe lithium‑ion traction battery installations. It is referenced in procurement, technical specifications and operational procedures for warehouses, manufacturing sites, ports and similar facilities using traction equipment.

FAQ

Q: What is this standard?

A: IEC 62485-6:2021 is an international standard that sets out safety and operational requirements for lithium‑ion battery installations used in traction and off‑road applications.

Q: What does it cover?

A: It covers safe operation, charging, monitoring, installation environment, maintenance, information/marking, risk assessment and emergency response for lithium‑ion traction battery installations; it does not cover vehicle design.

Q: Who typically uses it?

A: Manufacturers, integrators, facilities and safety engineers, maintenance teams, test labs and regulators involved with traction battery systems and equipment.

Q: Is it current or superseded?

A: The standard was published 5 January 2021 and is current; a corrigendum (IEC 62485-6:2021/COR1) was issued in February 2023 to correct/clarify items and is incorporated into consolidated copies. Users should apply the corrected (corrigendum‑included) edition.

Q: Is it part of a series?
