What is thermal insulation in lithium-ion battery modules?

Does insulating material affect battery pack temperature?

It is seen that the variation in the specific heat of the insulating material has almost no effect on the average pack temperature at the end of the parking phase. Consequently, the heater energy required to heat the battery packs remained approximately equal as seen in Fig. 31.

Does insulating a battery pack reduce fire risk?

The heat transfer is blocked by the insulation layers, and the Tpe of the next cell is slightly reduced by heat exchange with the ambient environment through radiation and convection. Thereby, it can be concluded that the addition of the insulation layers reduces the average Tpe of the battery pack which reduces the fire risks for the battery pack.
