The Large-Scale Combustion Laboratory is a comprehensive research facility dedicated to conducting full-scale fire experiments on energy storage systems. Its core mission lies in systematically studying the fire behavior and evolution laws of lithium-ion battery energy storage systems under thermal runaway conditions. With the rapid development of the new energy industry and the continuous expansion of energy storage power station scales, the fire risk of energy storage systems has become a key bottleneck restricting the safe development of the industry. Unlike traditional building fires, fires in energy storage systems involve complex processes such as internal thermal runaway of batteries, flammable gas ejection, thermal spread between multiple modules, and toxic gas release. Small-scale experiments cannot fully reproduce these phenomena, necessitating the full-scale testing capabilities of large-scale combustion laboratories. Such laboratories, by constructing full-scale energy storage containers or battery module arrays, equipped with high-precision heat release measurement systems, multi-component gas analysis networks, three-dimensional temperature field monitoring equipment, and high-definition imaging recording devices, are capable of simultaneously capturing the entire process information of the energy storage system from thermal runaway triggering, fire development, to final extinction.

As a pivotal platform for fundamental research and application verification in the field of energy storage safety, the large-scale combustion laboratory bears the significant mission of unveiling the intrinsic dynamics of energy storage fires, evaluating the efficacy of novel fire protection systems, and optimizing the layout design of power stations. The full-scale experimental data produced by the laboratory, encompassing heat release rate curves, thermal runaway propagation speeds, jet flame characteristics, and toxic gas release concentrations, serves as the cornerstone for establishing and validating numerical fire models. Furthermore, it provides direct scientific evidence for formulating energy storage safety standards and refining technical regulations. Through ongoing systematic experimental research, the large-scale combustion laboratory is constructing a solid scientific defense line for the safe and healthy development of the energy storage industry.
