Research on thermal propagation of battery modules based on thermal insulation materials with different thicknesses
Aiming at the thermal runaway suppression of lithium-ion battery,a mini module was triggered to study the effect of different materials and thicknesses of thermal insulation materials on thermal runaway suppression.The experimental results show that it was difficult to restrain the spread of heat between batteries only considering thermal insulation,and thermal runaway would occur in all batteries.The liquid cooling plate was added and a certain flow rate was set,and the heat spread was successfully suppressed under the synergistic effect of the thermal insulation material and the liquid cooling plate,and the heat dissipation and heat absorption of the second battery were quickly balanced without thermal runaway.The results provide a basis for selecting the most suitable insulation material scheme.
