Modelling and Comparison of Different Cooling Methods for a Lithium-Ion Battery Pack

Abstract: This paper describes and focuses on the major comparison between different cooling methods used for thermal management in a lithium-ion battery. It is the most suitable battery power alternative for electric vehicles. High power density, long-lasting life cycle, no memory effect, and minimal auto discharge features are the responsible factors behind its suitability. However, thermal issues related to Li-ion batteries can degrade the battery's performance and function. Therefore, selecting an appropriate cooling technique becomes essential for the commercialization of electric drive vehicles (EDVs). Fostering an ideal cooling control procedure to keep the temperature at an ideal scope of 20°C to 40°C is crucial for extending wellbeing, expanding the pack the board life, and decreasing costs. In this paper, we have considered three distinct types of cell cooling methods i.e. air, water, and PCM. Results have revealed that the temperature distributions inside the battery pack can be significantly affected by the type of coolant used. As compared to air, liquid coolant affects cooling 10-15 times faster.
