The increasing stipulation of electric vehicles underscores the critical requirement for effective thermal management in lithiumion battery systems, particularly during high-rate charging. Overheating and Capacity Degradation remain a primary challenge, as it impact battery safety, lifespan, and performance. The study examines a thorough evaluation of cooling techniques to improve battery packs’ thermal management under situations of fast discharge. A comprehensive analysis of heat generation and dissipation mechanisms within the battery cells has been conducted to identify critical factors influencing thermal performance in battery packs. This paper has been focused on battery pack temperature and state of charge analysis at different atmospheric conditions.
The air cooling technique is evaluated through simulation studies to determine the effectiveness of maintaining an optimal temperature range. The result demonstrates significant improvement in thermal regulation, exploring the benefits and limitations of the proposed cooling strategy. Simulation studies highlight the impact of air cooling on temperature control by using an autotune  Propotional-Integral-Derivatives controller, revealing significant improvements in thermal stability, battery lifespan, and overall efficiency by 13.11%. In addition to improving battery performance and longevity. It has been evaluated on the OPAL-RT real-time simulator’s test bench. The proposed strategy enhances the overall safety and efficiency of high-power battery systems. For the creation of efficient heat management techniques in the future of battery technologies, the study offers valuable suggestions.
