IEC 62619 Safety Testing Standard for Energy Storage Batteries

IEC 62619 focuses on the safety requirements for energy storage batteries and battery systems. It not only conducts safety tests such as external short circuit, impact, drop, thermal abuse, overcharge, and forced discharge on cells and battery modules, but also evaluates the functions of the Battery Management System (BMS), including overcharge voltage protection, overcharge current protection, overheating protection, and resistance to thermal runaway propagation.

 

As a standard for battery applications in industrial products, the release of IEC 62619:2017 fills the gap in lithium battery standards in this field. Lithium battery applications in industrial products include stationary products, such as telecommunications base stations, uninterruptible power supplies, energy storage systems, and emergency power supplies, as well as mobile products, such as forklifts, golf carts, automated guided vehicles, and other non-road vehicles.

 

In addition to covering traditional tests included in existing lithium battery standards, such as electrical tests, thermal tests, and mechanical tests, the new standard introduces dedicated sections to assess the Battery Management System (software evaluation). Previously, within the IEC system of battery standards, there were few clear requirements and assessment methods for the functional safety of batteries. With IEC 62619 standardizing the conventional safety and functional safety of industrial lithium batteries, it combines the trending technologies—functional safety and new energy batteries—effectively driving technological innovation and standard refinement.
