Does a battery energy storage system undergo thermal runaway?

The requirements were designed to evaluate the fire characteristics of a battery ESS that undergoes thermal runaway. The data generated was intended to be used to determine the fire and explosion protection required for an installation of a battery energy storage system.

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 to test thermal runway fire propagation in battery energy storage systems?

Test Method for Evaluating Thermal Runway Fire Propagation in Battery Energy Storage Systems. The primary measurement is heat release r nsumption calorimetry which is core to FTT’s product range and expe tise.FTT UL 9540A TestFTT supplies and installs the UL 9540A and trains clients in its use. FTT can also s

Why is thermal runaway a concern for ESS installations?

The greatest concern for ESS installations was thermal runaway in a battery module that could propagate to a significant fire or explosion, especially since there were no proven methods for controlling or suppressing a fire or mitigating a potential explosion.

What is the UL 9540a test methodology?

Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems UL 9540A 1.1 The test methodology in this document evaluates the fire characteristics of a battery... Find the most up-to-date version of UL 9540A at GlobalSpec.

What are the NFPA requirements for battery ESS?

Size (electrical capacity in a unit), separation and maximum allowable quantity (total electrical capacity in one space) requirements were introduced in the 2018 International Fire Code and the NFPA 1 Fire Code to address uncertainty with thermal runaway and fire propagation of battery ESS.
