Influence of Ventilation Placement on the Cooling Efficiency of Lithium-ion Batteries Under Forced Airflow Conditions
Year: 2024
Type: article
Abstract: In line with a rise in demand for lithium-ion batteries (LIBs) around the globe, LIB thermal management optimization is desirable. Moreover, the temperature rise of LIBs while discharging and charging affects their degradation and thermal runaway. The objective of this study is to investigate cooling performance in LIBs due to battery pack ventilation configuration. In this study, twenty 18650 lithium-ion cells (in 10S2P configuration) were simulated in Altair HyperWorks CFD - AcuSolve. The analysis provides a significant finding for the best thermal management approach by Design 2 with the position of an inlet at the top and outlet at the bottom of the battery pack, indirectly promoting uniform temperature distribution across the pack and avoiding local hot spots. These findings contribute significant insights into the effect of battery ventilation configuration for enhancing lithium-ion cooling performance
