High technology expertise and strong advancement in electric vehicles and Lithium (Li)-ion battery devices and systems have increased the speed of development and application of new equipment. It is reported that Li-ion battery life reduces almost by 60 days per degree temperature rise in an operational temperature of 30°C to 40°C, which makes cooling a high priority. The current study focuses on cooling the battery system using Phase Change Material (PCM) placed as bands of different dimensions around the prismatic battery. Eight novel designs of varying dimensions were constructed for three-volume scenarios. The heat generations considered in this study are 6,855 W/m3, 12,978 W/m3, 19,100 W/m3, and 63,970 W/m3. The data obtained was trained using an artificial neural network (ANN), and an equation was attained to fit the data. The optimum placement of PCM with respect to the number of bands and dimensions was achieved through a Genetic Algorithm. From the results of simulation studies, it can be interpreted that covering the full face of the cell gives the most optimal cooling rates. The optimization algorithm shows that the heat generation is directly proportional to the thickness of the PCM band, whereas it is inversely proportional to the height of the band. The optimal design depends on the heat generation of the cell. As the heat generation varies from 6,855 W/m3 to 19,100 W/m3, the optimized band height decreases from 196 mm to 100 mm by keeping the total volume of the PCM constant at 32,280 mm3 to maintain the maximum battery temperature between 303 K and 305 K.
