Simulation on the Thermal Management of Electrical Vehicle Battery Pack with Different Cooling Methods

EasyChair Preprint 10227

Abstract

Electrical vehicles (EVs) are becoming more popular every day. Lithium-ion (Li-ion) batteries in the cylindrical form are utilized as the power source of both electrical vehicles and hybrid electric vehicles due to their small size and high-power density. There is typically very little space between the batteries. Heat dissipation must be properly evaluated to ensure that the battery operates as intended. The study goal is to examine how well a battery pack performs overall while using alternating cooling strategies. Three models were created in Solidworks 2016 for the purpose of determining the best cooling approach. Three battery thermal management (BTM) options were also chosen, analyzed, and simulated in Ansys Fluent 19.2 to ensure accurate thermal modeling. According to the findings, geometry 2 ethynyl glycol exhibits a more efficient temperature distribution and maximum temperature than the other cooling methods. Furthermore, in channel cooling based on BTMs, the consistent temperature distribution is carried out, and the maximum temperature is regulated to 306.66 K, with a minimum temperature of 293. 20 K being attained.
