Finland, Sept. 11 -- Technology group Wartsila has successfully completed large-scale testing of its proprietary Active Ignition Mitigation System (AIMS). AIMS is engineered to mitigate potential flammable gas build-up during an abnormal thermal scenario within battery energy storage systems (BESS). With this milestone, Wartsila becomes one of the first BESS integrators to demonstrate the effectiveness of an integrated explosion control system.In July, Wartsila conducted a series of three rigorous full-system tests in the United States. Each test simulated worst-case thermal runaway scenarios within Wartsila's Quantum2 containerised BESS enclosure. During the tests, a flammable gas blend, representative of UL 9540A CATL 306Ah cell-level tes...
