Abstract :This study explores the advanced thermal management of lithium-ion batteries (LiBs) using a comprehensive Battery Thermal Management System (BTMS) framework. Employing numerical simulations and experimental validations, the research evaluates three distinct cooling configurations (Case 1, Case 2, and Case 3) under varying coolant flow velocities (0.1 m/s, 0.5 m/s, and 1 m/s) and coolant types (water and ethylene glycol). Incorporating nanofluids, the study demonstrates significant improvements in heat transfer efficiency compared to conventional methods. Findings reveal that higher flow velocities enhance heat dissipation and temperature uniformity. Additionally, water outperforms ethylene glycol due to its superior thermal conductivity. A temperature gradient from 298 K to 318 K underscores the importance of optimized flow distribution and channel geometry. This work not only addresses critical challenges in LiB thermal management but also offers significant insights into the design of safer and more efficient cooling systems for applications such as electric vehicles and renewable energy storage. In addition to providing theoretical insights, this research offers actionable recommendations for the design of such systems. Future directions for this research include the integration of microchannel cooling and phase change materials to further enhance thermal performance.
