Seyed Morteza Mousavi-khoshdel Department of Chemistry, Iran University of Science and Technology Amir Bahador Nemati School of Automotive Engineering, Iran University of Science and Technology Journal Article 2018 05 13 There are two major challenges for today’s world: urban air pollution and the concern that fossil fuels will end, which forces humans to replace fossil fuels sources with renewable energy sources; the automobile industry can have a key role in tackling of both challenges. To overcome these challenges, during the last decade, the development of electric vehicles has been on the agenda for the automotive industry. Lithium-ion rechargeable batteries play a vital role in these vehicles. The performance, safety and life of these batteries are very much affected by their operating temperature. In this study, with the help of experimental data, a lithium-ion battery cell is simulated using the ANSYS Fluent software via a two-potential model. The time variations of the voltage and maximum cell temperature along with the temperature distribution at four constant discharge rates of 2C, 3C, 7C, and 9C and the discharge profile of dynamic stress test -which is a special profile used for testing hybrid vehicles battery systems- are presented. The simulation results indicate that high temperatures as 45 <em>C</em> are also experienced during the dynamic stress test. Such a temperature which could lead to a battery thermal runaway would be a hazard to the battery and electric vehicle.
