Heat Generation & Thermal Fatigue in EV Batteries with Different C-Ratings using Abaqus and Fe-Safe

In the pursuit of more efficient and powerful electric vehicles, understanding the intricate relationship between battery performance and thermal dynamics has become paramount. The project, "Assessing Heat Generation and Resulting Thermal Fatigue based on S-N Curve for Electric Vehicle Batteries with Different C-Ratings," delves into this crucial junction. By subjecting electric vehicle batteries to varying charge and discharge rates, represented by different C-ratings, researchers aim to quantify the resultant heat generation. This heat, often a consequence of internal resistance and inefficiencies, can profoundly influence battery longevity and safety. Moreover, the project extends its investigation to the realm of thermal fatigue, a phenomenon characterized by the stresses endured due to cyclic temperature changes. Drawing parallels with the S-N curve used to depict material fatigue, the project seeks to develop a comprehensive understanding of how thermal fluctuations impact battery performance over time. Such insights hold the key to designing battery systems that can withstand the rigorous demands of electric vehicle operation. Ultimately, this Endeavor aspires to enhance both the efficiency and durability of electric vehicle batteries, contributing to the advancement of sustainable transportation solutions
