### Abstract

In order to meet the operating temperature requirements of lithium batteries, air-conditioning parallel cooling battery packs are used when the ambient temperature is high in summer. Through the orthogonal analysis method, the study compared the influence of the diameter of the air inlet, the air temperature and the flow velocity on the cooling effect, and concluded that the cooling air temperature has the most significant effect and the flow velocity has the least significant effect. Through the TOPSIS method, three indicators of the module's maximum temperature, maximum temperature difference, and air conditioning power are selected, and the air temperature is comprehensively evaluated, and concluded that the optimal temperature of the cooling air is 291.15K.
