摘要：

开空调引起“实际续航里程显著缩短”是制约电动汽车发展的一大因素，如何降低空调系统能耗成为现阶段各大主机厂亟待解决的难题。本文综合考虑新风需求与能耗之间的平衡，提出制冷工况下汽车座舱新风比例智能控制策略，并针对基准通风方式与智能新风控制方式的节能效果进行了分析。分析发现新风比例智能控制策略可以显著降低空调系统能耗，环境温度为40 ℃时，压缩机能耗最大可降低约49.7%，电量为100 kW·h的电动汽车最多可增加实际续航82 km。

Abstract:

The development of electric vehicles is restricted by the "significant reduction of actual mileage" caused by air-conditioning. How to reduce the energy consumption of air-conditioning system is an urgent problem to be solved by electric vehicle manufacturers. Considering the balance between fresh air demand and energy consumption， this paper proposes an intelligent control strategy for the proportion of fresh air in the vehicle cabin under air-conditioning conditions， and compares the energy-saving effect of the standard ventilation mode and the intelligent fresh air control mode. The analysis shows that the fresh air proportion intelligent control strategy can significantly reduce the energy consumption of the air conditioning system. When the ambient temperature is 40 ℃， the energy consumption of the compressor can be reduced by about 49.7%， and the actual endurance mileage of the electric vehicle with the battery capacity of 100 kW·h can increase by about 82 km.
