Abstract
With the recent explosion of the global electric vehicle (EV) market comes the need for improved battery technology, and specifically battery cooling system performance. Heat pipes play an important role in the thermal management of electric vehicle (EV) batteries, ensuring efficient and reliable cooling to maintain optimal operating temperatures. The primary function of heat pipes in EV battery cooling is to dissipate excess heat generated during the charging and discharging processes. As the battery operates, it experiences fluctuations in temperature, and excessive heat can degrade battery performance and lifespan. Heat pipes can help regulate these temperatures by absorbing and transporting heat away from critical components. By using heat pipes, EV manufacturers can enhance the overall thermal performance of the battery, contributing to increased energy efficiency, extended battery life, improved operating performance and improved safety. In this paper, the application of heat pipe technology to meet the cooling challenges of modern EV battery packs is studied. Heat pipe size, shape, and configuration in EV battery applications is presented. Working fluid choices are highlighted. Configurations of Battery Thermal Management Systems (BTMSs) using heat pipes are presented. The use of nanofluid particles in the working fluid to enhance the heat pipe efficiency is presented.
