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.

The life and efficiency of electric vehicle batteries are susceptible to temperature. The impact of cold climate dramatically decreases battery life, while at the same time increasing internal impedance. Thus, a battery thermal management system (BTMS) is vital to heat and maintain temperature range if the electric vehicle’s batteries are operating in a cold climate. This paper presents an induction heater-based battery thermal management system that aims to ensure thermal safety and prolong the life cycle of Lithium-ion batteries (Li-Bs). This study used a standard simulation tool known as GT-Suite to simulate the behavior of the proposed BTMS. For the heat transfer, an indirect liquid heating method with variations in flow rate was considered between Lithium-ion batteries. The battery and cabin heating rate was analyzed using the induction heater powers of 2, 4, and 6 kW at ambient temperatures of −20, −10, and 0 °C. A water and ethylene glycol mixture with a ratio of 50:50 was considered as an operating fluid. The findings reveal that the thermal performance of the proposed system is generally increased by increasing the flow rate and affected by the induction heater capacity. It is evident that at −20 °C with 27 LPM and 6 kW heater capacity, the maximum heat transfer rate is 0.0661 °C/s, whereas the lowest is 0.0295 °C/s with 2 kW heater capacity. Furthermore, the proposed BTMS could be a practical approach and help to design the thermal system for electric vehicles in the future.
