AB - Lithium-ion batteries have become more and more recently. Because of their more density of energy and extended life cycle. In this research investigate the paraffin wax and composite phase change material (CPCM) were used to make a hexagonal and trapezoidal-shaped lithium-ion battery pack. Because thermal conductivity of paraffin wax is very low, to increase thermal conductivity adding carbon-based material of graphite powder. Without cooling, PCM cooling, and CPCM cooling studies on the battery module were all done. This investigation found that environment temperature of 28-32°C, the experiment utilized three different discharge rates of 1C, 2C, and 3C. At all discharge rates, the CPCM with hexagonal battery pack has demonstrated good performance by keeping its temperature below 50°C. In related to PCM cooling, the peak temperature was decreased by 6.7%, 9.1%, and 8.9% at 1C, 2C, and 3C. The CPCM-with trapezoidal based battery pack lowered the high temperature increase by 14.2% when related to the PCM-based battery pack. Additionally, it reduced the temperature variance of the trapezoidal battery pack.
