Energy storage battery system safety test

Are batteries for stationary battery energy storage systems safe?

Batteries for stationary battery energy storage systems (SBESS), which have not been covered by any European safety regulation so far, will have to comply with a number of safety tests. A standardisation request was submitted to CEN/CENELEC to develop one or more harmonised standards that lay out the minimum safety requirements for SBESS.

Do battery energy storage systems need ul 9540a testing?

Building and fire codes require testing of battery energy storage systems (BESS) to show that they do not exceed maximum allowable quantities and they allow for adequate distancing between units. UL 9540A is the consensus test method that helps prove systems comply with fire safety standards.

How should a battery safety test be reported?

The SAE recommends that results of each test should be reported in terms of the Hazard Severity levels described in Table 8, and the use of such information in Battery safety and Hazard risk migration approaches. Rechargeable Energy Storage System (RESS) responses in abusive tests should be determined. Table 8.

Why do you need ESS battery testing?

Stationary lithium-ion storage systems, which are increasingly popular due to their energy density and cyclic strength, impose special demands on safety which must be met. ESS battery testing provides multiple benefits to you as manufacturer and to your customers:

What is ESS battery testing & certification?

ESS battery testing and certification according to international standards Energy storage systems (ESS) are important building blocks in the energy transition. An ESS battery can be used to efficiently store electricity from renewable sources such as wind and solar.

What is a battery safety test?

“This test shall evaluate the safety performance of a battery in internal short-circuit situations. The occurrence of internal short circuits, one of the main concerns for battery manufacturers, potentially leads to venting, thermal runaway, and sparking which can ignite the electrolyte vapours escaping from the cell.
