Abstract

Effective thermal management is crucial for ensuring the safety, durability, and efficiency of battery systems, particularly under high-load conditions. This research investigates the impact of various fan arrangements on the temperature characteristics of a lithium-ion (LiB) battery module. Three different battery thermal management systems (BTMS) were set and stated as BTMS I, BTMS II, and BTMS III. In BTMS I, one fan was located at the inlet, and a hole was left at the outlet. In BTMS II, two fans were located side by side at the inlet, with the outlet configured the same as in BTMS I. Lastly, in BTMS III, one fan was placed at the inlet, and another at the outlet. Reductions of up to 27.8% in maximum cell temperature (Tmax) and up to 57.2% in maximum cell-to-cell temperature difference (TD) were achieved with BTMS I and BTMS II, respectively.
