IEC 62619 certification is an international standard for the safety performance of lithium energy storage batteries, developed by the International Electrotechnical Commission (IEC). The standard aims to ensure the safe and reliable operation of energy storage lithium batteries in various industrial applications, covering the electrical performance, mechanical performance, environmental adaptability and safety performance of the battery.

1. IEC 62619 Standard Overview

: batteries and batteries containing alkaline or other non-acid electrolytes-safety requirements for industrial lithium batteries and batteries (Secondary cells and batteries containing alkaline or other non-acid electrolytes - Safety requirements for secondary lithium cells and batteries, for use in industrial applications).

Issued by: International Electrotechnical Commission (IEC).

release time: there are multiple versions, such as IEC 62619:2017 and IEC 62619:2022, different versions may be updated in details.

nature: it belongs to the category of voluntary certification, but it is widely used in many countries and regions, such as Europe, Australia, Japan, etc., as the basic standard of battery system in power energy storage system certification.

2. IEC 62619 Scope

IEC 62619 standard is mainly used for energy storage batteries and battery systems in industrial products, including stationary applications (such as power energy storage systems, uninterruptible power supplies, backup power supplies, etc.) and power applications (such as electric forklifts, trackless trucks AGV, rail vehicles and other non-road vehicles). The standard does not apply to lithium batteries for electric road vehicles, which follow the IEC 62660 standard.

4. IEC 62619 standard update

Take IEC 62619:2022 as an example. Compared with the previous version, the standard has made a number of updates, including:

the safety requirements for the moving parts of the new battery system, such as anti-pinch and anti-misoperation.

strengthens the protection requirements for dangerous live parts, and introduces the concepts of tool accessibility and standard test fingers.

has added a laser-induced thermal runaway propagation test to simulate the safety performance of batteries at extreme temperatures.

explicitly required to comply with IEC 61000.
