Heat Distribution Study in Li-Ion Battery with Different Cell Configuration

Abstract

This project delves into the intricate interplay between different cell configurations and the thermal performance of lithium-ion battery packs. A comprehensive study is conducted to elucidate the effects of various cell shapes and structures on heat distribution during charging and discharging cycles. A robust computational model is developed to simulate temperature patterns within the battery pack, employing advanced simulation tools such as Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD). The model's accuracy is rigorously tested by constructing a small-scale battery pack featuring interchangeable cell configurations. Hands-on experimentation involves measuring temperature distribution under diverse operating conditions, providing valuable real-world data. The experimental results are meticulously compared with the predictions from the simulation model, ensuring a thorough validation process. This multi-faceted approach advances our understanding of thermal dynamics in lithium-ion batteries and contributes to enhancing battery safety and efficiency. Furthermore, this project serves as an educational platform, offering students practical insights into battery pack construction, exposure to sophisticated simulation tools, and an opportunity to develop proficiency in thermal management strategies. The knowledge gained extends beyond the immediate focus on lithium-ion batteries, providing a foundation for understanding and optimizing thermal applications in various energy storage systems.
