IEC 62619:2017

Overview

IEC 62619:2017 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies safety requirements for secondary lithium cells and batteries containing alkaline or other non-acid electrolytes. This standard is particularly focused on secondary lithium cells and batteries intended for use in various industrial applications, including stationary and motive purposes. It ensures the safe operation, handling, and testing of lithium battery systems, catering to industries requiring reliable power sources.

The scope of IEC 62619:2017 covers batteries used in applications such as telecom, uninterruptible power supplies (UPS), electrical energy storage systems, utility switching, emergency power, as well as motive applications like forklift trucks, golf carts, automated guided vehicles (AGVs), railways, and marine uses (excluding road vehicles).

Key Topics

• Safety Requirements: The standard defines minimum and common safety requirements across various industrial applications to minimize risks during battery use.
• Testing Procedures: IEC 62619 outlines rigorous test conditions and methods such as external short-circuit tests, impact tests, drop tests, thermal abuse, overcharge, and forced discharge tests to simulate realistic misuse and abuse scenarios.
• Battery System Safety: The standard includes guidelines for battery management systems (BMS) to ensure overcharge control, current regulation, thermal management, and risk mitigation of thermal runaway propagation.
• Operating Region: Specifies safe charging, discharging, and temperature ranges for batteries to avoid hazardous situations.
• Design and Assembly: Addresses considerations for assembling cells into modules or battery packs, emphasizing insulation, wiring, venting, and terminal contacts to prevent failures.
• Risk Analysis: Focuses on electrical safety as part of overall risk management, though detailed electrical safety measures are deferred to application-specific standards.
• Information and Markings: Sets out requirements for safety information, product markings, and declarations by manufacturers to ensure clear communication of tested units and safety instructions.

Applications

IEC 62619:2017 covers a wide range of industrial applications where secondary lithium cells and batteries are critical to operation and safety, including:

• Stationary Applications

  • Telecom infrastructure power backups
  • Uninterruptible Power Supply (UPS) systems
  • Electrical energy storage solutions for utilities
  • Emergency power systems and utility switching devices

• Motive Applications (excluding road vehicles)

  • Forklift trucks and warehouse vehicles
  • Golf carts and automated guided vehicles (AGVs)
  • Railway battery systems for traction or auxiliary power
  • Marine battery applications for onboard electrical power

This standard ensures consistent safety measures are applied for diverse industrial uses, providing a baseline for manufacturers and operators to implement robust battery safety management.

Related Standards

• IEC 62660 Series: Specifies safety and performance requirements for lithium cells used in road vehicles and takes precedence over IEC 62619 in case of conflicts for automotive applications.
• IEC 62133: International standard covering safety requirements for portable secondary cells and batteries containing alkaline or other non-acid electrolytes; complementary for certain battery types.
• ISO/IEC Directives: Provides guidelines followed for drafting and maintaining the IEC 62619 standard.
• Other IEC standards and technical reports provide test procedures, terminology, and detailed safety assessments that support or complement IEC 62619 requirements.
