Abstract
Battery cooling is essential to prevent battery damage. Lithium-Ion batteries do not perform well at high temperatures ;thus, by designing thermal management systems, the temperature of the batteries remains within the permissible range. In this paper, a Lithium-Ion battery is modeled electrically and thermally. The purpose is to investigate the temperature rise and the voltage drop of the battery and manage temperature rising by the cooling system. The results show that when the battery is discharged at a rate of 1c, the battery temperature reaches 318K and at a rate of 2c, the battery temperature reaches 335K which can cause damage. To overcome this problem, a cooling system is designed. In this system, temperature decreases to 303K for 0.01 m/s flow velocity in discharge rate of 2c. In addition, the battery cooling is investigated by using octadecane and nonadecane phase change materials. When octadecane and nonadecane are used, the battery temperature decreasesto 308K and 310K, respectively. The results show that octadecane material has a better cooling performance for the battery.
