EticaAG Completes the First UL 9540A Thermal Runaway Propagation Testing for an Immersion-Cooled Battery Energy Storage System

EticaAG has completed the battery energy storage industry’s first UL 9540A thermal runaway propagation testing for an immersion-cooled battery system. Pre-test trials showed thermal runaway could not be induced with immersion cooling active, requiring removal of the dielectric fluid to generate propagation data for the official UL 9540A procedure used in permitting and safety evaluations.
