This study addresses the critical challenge of fast-charging lithium-ion batteries for electric vehicles while maintaining safety and longevity. Two optimized charging profiles (MSCC and spline-based) are developed to minimize charging time while respecting voltage and temperature constraints. The research utilizes both cell and battery module models to solve this optimization problem. A key innovation is the investigation of dual-side cooling, employing both top and bottom cooling plates simultaneously. This novel thermal management approach significantly reduces thermal gradients and promotes uniform temperature distribution across battery cells, enhancing the overall charging process. The study also explores modifications to cell internal connections to improve performance. The optimized cooling configuration demonstrates substantial improvements, reducing charging time by 30 % compared to the test bench configuration and decreasing thermal gradients by 63 % relative to high-convection bottom cooling. These results underscore the importance of advanced thermal management in fast-charging applications. Additionally, the research proposes an implementation solution to address discrepancies between the model used for profile optimization and the actual battery characteristics. This adaptive approach ensures the optimal charging profiles remain effective when applied to real-world systems. By integrating optimized charging profiles, efficient cooling systems, and sophisticated modelling techniques, this study provides valuable insights for achieving faster and safer charging of lithium-ion batteries. The findings have significant implications for advancing electric vehicle technologies and addressing key barriers to widespread EV adoption.< Leer menos
