The fast-growing electric vehicle market demands robust and efficient thermal management solutions for battery packs, such as gap fillers and thermal pads. Gap fillers outperform thermal pads to achieve lower thermal impedance, as the gap fillers conform to surface roughness before curing. This allows gap fillers to adhere well to surfaces and provide mechanical support during normal operation. However, this also poses a challenge during repair, removal and re-manufacturing. Currently, there is no set standard for measuring vertical pull-off, and hence, there is a lack of knowledge on what level of pull-off force is needed to service these battery packs.
