Abstract
Battery packs used in automotive powertrains either electric vehicles or hybrid electric vehicles support heavy electrical loads resulting in significant heat generation within them. Cooling systems are embedded to regulate the battery pack temperatures, helping in maintaining the battery condition and slowing down the aging of the batteries. Therefore, a good battery cooling system is important for the superior performance of the battery. So, in this paper, an analysis was reported on the nature of the thermal performance of the liquid-cooled battery module system using a three-dimensional computational fluid dynamics simulation with different cooling mediums and variable inlet velocities. The minimum temperature, average temperature and maximum battery cell temperature at a module discharge rate of 2C are assessed to find the optimal coolant for different velocities.
