Free QuoteWith an increase in cooling flow rate and a decrease in temperature, the heat exchange between the lithium-ion battery pack and the coolant gradually tends to balance. No datasets were generated or analysed during the current study.
To simulate the thermal behavior and airflow characteristics of the lithium-ion battery pack system, a steady-state computational fluid dynamics approach was employed using Ansys Discovery 2024 R1 and Ansys Workbench 2024 R1.
This study presents a comprehensive thermal analysis of a 16-cell lithium-ion battery pack by exploring seven geometric configurations under airflow speeds ranging from 0 to 15 m/s and integrating nano-carbon-based phase change materials (PCMs) to enhance heat dissipation.
However, the thermal performance of lithium-ion batteries is a major concern, as overheating can lead to safety hazards. This study aims to investigate the impact of structural parameters on the temperature field of battery packs, with a focus on, the width of wedge-shaped channels, inclination angles, and gaps between battery cells.
According to research experience, the temperature distribution of lithium-ion batteries is usually determined by changes in the internal heat flux of the battery, including the heat generated internally and its conduction to the external environment.
The thermal changes inside lithium-ion batteries are affected by parameters such as electrochemical reaction rate, entropy coefficient, diffusion coefficient, and open-circuit voltage.
