Why is ESS battery testing important?

ESS battery testing is crucial for ensuring the safety of stationary lithium-ion storage systems. These systems, which are increasingly popular due to their energy density and cyclic strength, impose special demands on safety that must be met. ESS battery testing provides multiple benefits to you as a manufacturer and to your customers.

How to test a battery?

To obtain the most reliable results, testing activities should be carried out at dedicated battery testing laboratories. These facilities are often equipped with multiple testing devices specifically designed for testing battery cells, modules and complete packs or even systems.

Is energy storage device testing the same as battery testing?

Energy storage device testing is not the same as battery testing. There are, in fact, several devices that are able to convert chemical energy into electrical energy and store that energy, making it available when required.

How can I ensure the safety of my battery?

To ensure the safety of your battery, TÜV SÜD tests stationary lithium-ion batteries according to IEC 62619. This standard addresses safety testing at cell level. After successful testing, you can apply a CE mark as declaration of conformity to your product.

What is a battery testing facility?

These facilities are often equipped with multiple testing devices specifically designed for testing battery cells, modules and complete packs or even systems. Testing can include electrical, mechanical and/or thermal test programs.

What are energy storage systems?

Energy storage systems (ESSs), and particularly battery energy storage systems, are finding their way into a very wide range of applications for utilities, commercial, industrial, military and residential power. Applications include renewable integration, frequency regulation, critical backup power, peak shaving, load leveling, and more.
