en پژوهشي Research With respect to the limitations of fossil energy resources, different types of electric vehicles (EVs) are developed as suitable alternatives. Lithium-ion (Li-ion) battery cells play an extremely important role in EVs due to their unique features. But they need a thermal management system (TMS) to maintain their surface temperature uniformity and avoid them from thermal runaways. In the current study a phase change material (PCM) based TMS is introduced and applied to provide a uniform temperature distribution on a Li-ion battery cell surface. This PCM based TMS declines the final maximum temperature difference to (1/5) and (2/3) at 1 C and 2 C discharge rate respectively.<br> &nbsp; Electric vehicles, Li-ion battery, Thermal management system, Phase change material 2848 2853 http://ase.iust.ac.ir/browse.php?a_code=A-10-316-2&slc_lang=en&sid=1 Sina Jenabi Haqparast sinajenabihaghparast@yahoo.com 180031947532846002292 180031947532846002292 No Iran University of Science and Technology Gholam Reza Molaeimanesh molaeimaneh@iust.ac.ir 180031947532846002293 180031947532846002293 Yes Iran University of Science and Technology Seyed Morteza Mousavi-Khoshdel mmousavi@iust.ac.ir 180031947532846002294 180031947532846002294 No Iran University of Science and Technology
