Abstract
Batteries have become one of the most important components of electronic devices. However, a large issue lies in overheating batteries, which decreases their performance and lifespan. Although cooling systems have been researched to combat this, the combination of phase change material polyethylene glycol (PEG) and fans has not been observed. The purpose of this study was to determine if a hybrid system consisting of PEG and air cooling would decrease temperatures compared to individual cooling systems such as just air cooling. It was hypothesized that the hybrid cooling system would have lower overall temperatures as compared to individual active and passive cooling systems as combining the two methods has been found to decrease temperatures in batteries (Mohammed et al., 2024). Four Lithium-ion batteries were taken and connected to twelve 0.5Ω resistors in a 4 series 3 parallel. Tests were conducted using no cooling, forced air cooling, PCM cooling with PEG, and a hybrid system combining forced air cooling and the PEG, and temperatures were measured every 2 minutes for 6 minutes. Based on a two-way ANOVA test with a p < .05, (F(3, 234) = [132.81], p < .0001) between cooling methods and (F(2, 234) = [262.37], p < .0001) between time, so the null hypothesis could be rejected. A post-hoc Tukey test was performed and all except the forced air vs PEG comparison were significant. Therefore, there is significant evidence that a hybrid cooling system consisting of PEG and fans could decrease temperatures more than individual systems.
