Experimental Investigation on Single-Phase Immersion Cooling of a Lithium-Ion Pouch-Type Battery under Various Operating Conditions

The selection of a battery thermal management technique is important to overcoming safety and performance problems by maintaining the temperature batteries within desired range. In this study, LiFePO4 (LFP) pouch-type having capacity 20 Ah was experimentally cooled with both air liquid (immersion cooling) techniques. Distilled water selected as immersion fluid in experiments, impact discharge rate (1–4C), ratio (50–100%), coolant inlet (15–25 °C) on were investigated during period. experiments revealed that maximum temperatures reached at approximately 45 °C 33 for distilled cooling techniques, respectively, 4C. average surface can be reduced 28% 25%, implementation 4C compared technique. Moreover, demonstrated difference could lowered 4 means 100% highest rate, where they are 11 12 50% cooling, respectively. addition, it observed has significant %100 immersion.
