알루미늄 냉각 판을 이용한 하이브리드/전기차용 배터리 냉각시스템의 수치적 연구

초록

The battery cells in lithium-ion battery pack assembled with high-capacity and high-power pouch cells, arecommonly cooled with thin aluminum cooling plates in contact with the cells. For HEV/EV lithium-ion battery systemsassembled with high-capacity, high-power pouch cells, the cells are commonly cooled with thin aluminum coolingplates in contact with the cells. Thin aluminum cooling plates are cooled by cold plate with coolant flow paths. In thisstudy, the effect of the battery cooling system design including aluminum cooling plate thickness and various positionof cold plate on the cooling performance are investigated by using finite element methods (FEM). Optimal cooling plateand cold plate design are proposed for improving the uniformity in temperature distributions as well as loweringaverage temperature for the cells with large capacities based on the simulation results.
