“…By optimizing the key control parameters, they achieved a significant reduction of 65.5% in the maximum temperature difference compared to the original model. Ibrahim et al [ 12 ] presented the results on pressure drop, average, and maximum temperature of a battery pack containing 45 cylindrical cells arranged rhombically with one inlet and two outlets of varying sizes at different flow velocities. As per their observations, the inflow velocity showed a positive effect on pressure drop while a deleterious effect on the battery temperature.…”

The significant heat generated during the operation of lithium‐ion batteries raises the battery temperature thereby leading to performance degradation and thermal runaway in a thermal abuse environment. Therefore, a simple but effective battery thermal management system (BTMS) is crucial to achieve the permissible operating temperatures. In this work, the performance of air‐cooled BTMS is evaluated by changing the arrangement of cells under discharging conditions. Seven distinct arrangements (trapezoidal, slanted, cross, aligned, staggered, tilted square, and zigzag) of lithium‐ion cells are investigated in a rectangular battery pack. Two‐way coupling of 1D electrochemical model and 2D conjugate thermal‐fluid model is employed. The increasing Reynolds number reduces the cell temperature due to augmented convective effects. Under otherwise identical conditions, the zigzag cell arrangement outperforms the other cell arrangements but at the expense of the highest pressure drop (≈threefold). Particularly, the values of average and maximum cell temperature are reduced by ≈5K and ≈4K, respectively, for Re = 1000 at 1C in comparison to the aligned cell arrangement. Similarly, the least favorable performance is predicted by the trapezoidal, slanted, and cross‐cell arrangements. Finally, a performance plot is suggested considering the trade‐off between the power requirement and the cooling enhancement.
