Study on thermal runaway simulation of lithium battery energy storage system for naval platform

ObjectiveWith the continuous advancement of high-energy weapon technology, energy storage systems are becoming increasingly crucial for maintaining stable energy supply on naval platforms. Therefore, this paper simulates thermal runaway in lithium battery energy storage systems on naval platforms.MethodsFirst, using Fluent and Simulink software, simulation models for submerged and liquid-cooled plate energy storage systems are constructed. Based on the actual working conditions of a specific vessel, thermal runaway simulation experiments were conducted. ResultsThe results show that, compared to the liquid-cooled plate method, the submerged cooling method exhibits superior performance in managing thermal runaway, is better at controlling temperature fluctuations, and maintains system stability, which makes it more promising for naval platform applications. ConclusionThis research provides reference for the safety control technologies of energy storage systems used on naval platforms.
