Influence of Insulation Material Thickness on Spread of Thermal Runaway in Battery Packs

Thermal runaway occasionally happens in batteries. A single battery, after thermal runaway, will release heat and transfer it to neighboring batteries, leading of battery packs. Thus, is necessary explore the diffusion law modules. Heating by far most common way trigger propagation In this paper, experiments simulations were conducted influence different insulation thicknesses on lithium iron phosphate result shows that best thickness between adjacent batteries 2 mm. For complex modules, simulation analysis when spacing modules pack was 10 mm occurred one side pack, did not occur other for a certain period time. Therefore, recommended This lays foundation safe design
