Abstract

The cell arrangement is one of the most crucial rules for designing an efficient cooling system of the lithium-ion battery pack in electric vehicles (EVs). This study focused on the decreasing of the temperature of the battery pack with simple arrangements that utilized the space and the turbulent airflow passing the battery pack was considered. Furthermore, this paper aims to comparative analysis of different arrangements (aligned, staggered) with an increasing number of columns and adjusting the gaps between the cells to reduce the temperature of the battery. Parametric analysis effected on the cooling performance is studied on a cylindrical battery pack with a forced air-cooling system in axial-flow configuration based on computational fluid dynamics (CFD). The results showed that the increase in the number of columns leads to reduce the air velocity and lower the heat dissipation of the battery. Furthermore, the aligned arrangement has the best cooling performance. After adjusting the gaps between the center of battery cells found that the temperature decreased by increase the gaps between cells due to the gaps lead to improve the turbulent flow which was larger heat transfer and the gap at 13 mm is the best option in this study.
