CLOU Aqua C2.5 Establishes Unprecedented Safety Benchmark with 59-Hour Large-Scale Fire Test

CLOU Aqua C2.5 5MWh liquid-cooled energy storage system has successfully completed an extraordinary 59-hour and 10-minute Large-Scale Fire Test - setting a new benchmark for energy storage safety evaluation. The test was fully witnessed and documented by CSA Group personnel throughout the entire process. The system demonstrated exceptional resilience by maintaining complete structural integrity while withstanding temperatures exceeding 1,300°C, without resulting thermal runaway propagtion between initiating BESS and target BESSs nearby.

The Large-Scale Fire Test is designed to evaluate the possibility of fire spreading from one system enclosure to adjacent systems in centralized installations of energy storage systems. During the test, under conditions where the triggered system was fully engulfed in flames, the fire did not cause any adjacent systems to exhibit valve opening or thermal runaway signs. This demonstrates the product's exceptional flame-retardant and thermal insulation performance, meeting the customized testing requirements of the client.

This testing milestone embodies Clou's profound commitment to addressing clients' safety imperatives.By ignition of Container A, sustained combustion persisted for 59 hours and 10 minutes until complete extinguishment without reignition. The testing methodology accurately simulates the full progression of extreme fire scenarios - from ignition, escalation to natural attenuation. The obtained critical data provides essential parameters for optimizing fire protection system design in energy storage plants..

"The test results have far exceeded our most stringent safety benchmarks. CLOU's integrated approach combining superior flame retardancy, advanced thermal management and inherent system protection represents a significant advancement in energy storage safety engineering." Eric Wang, System Director of CLOU ESS Division emphasized the solution's forward-looking design, specifically engineered to address emerging challenges posed by high-energy-density battery technologies.
