Simulation
In the design of battery energy storage systems, in accordance with NFPA 855, the design of explosion-proof systems must be taken into account, especially in response to thermal runaway events. Preventing deflagration (the combination of explosion and combustion) is crucial. At this time, the model can be used for analysis, simulation analysis based on the cell level test data, combined with the structural design of the product, to verify the safety of the system.
By simulating the combustion characteristics under different situations, verify whether the released gas will reach the explosion limit under certain conditions, as well as the potential dedetonation intensity and consequences. Evaluate whether the ventilation system can effectively expel harmful gases and prevent gas concentrations from reaching dedetonation limits. At the same time, the role of the explosion-proof system in the protection system is analyzed, such as pressure relief devices, explosion-proof wall layout, etc.
With these tools, thermal runaway and associated risk scenarios can be simulated in detail in energy storage systems. This ensures that the explosion-proof system design, product design meets the relevant standards and ensures the safe operation of the battery energy storage system.
