Abstract

This study examines the use of liquid cooling systems and phase change materials (PCMs) to control the temperature of lithium iron phosphate battery packs. The objective is to satisfy the 5C battery pack's heat dissipation requirements. The impacts of several factors, such as phase change temperatures, liquid flow rates, and delayed cooling start times, on the battery pack's temperature are examined using commercial CFD code. The findings of the study show that the battery pack's temperature dropping is slowed down with an earlier start of liquid cooling. Also, the temperature differential and rise of the battery gradually decrease as the cooling liquid's flow rate increases.
