Battery thermal management system using nano enhanced phase change materials

Abstract Electric vehicles are being developed as a crucial tool in the fight against global warming and car pollution. As a result, battery heat management is critical for optimal operation in all climates in electric vehicles (EVs) and hybrid electric vehicles (HEVs). Extreme or higher temperatures may cause the battery’s maximum voltage to drop and its durability to deteriorate. An effective battery cooling system is required for the safe operation of electric vehicles throughout their lifecycle. The current work involves the simulation of a battery thermal management system that employs nano-enhanced phase change materials (NEPCM). Ansys Fluent is used to conduct the numerical analysis. To test the thermal performance, paraffin wax is used as the base fluid, into which various combinations of nanoparticles such as Copper Oxide, Copper, and Multi Walled Carbon Tube (MWCNT) are disseminated. The parametric study is carried out by altering the battery temperature and nanoparticle volume fraction. The findings show that at large particle volume fractions, the battery system’s heat transmission properties are greatly improved. The findings of this study will aid in the identification of optimal NEPCMs with increased thermal performance.
