最近，中国特大城市遭受了严重的空气污染。以往的研究指出，交通系统已成为空气污染的主要来源之一，道路上的污染物浓度明显高于非道路。电动汽车（EV）的引入被提出作为一种方法来缓解目前的情况。为了更好地了解电动汽车在北京的使用效益，已经开发了一个模拟平台，以评估在选定的区域内使用电动汽车的空气质量的改善定量。研究结果表明，当电动汽车普及率为5%、10%、15%时，PM2.5、NOx、CO的排放量分别减少0.86%、9.01%、12.23%、0.92%、9.01%、13.32%、0.95%、8.86%、13.73%。结果显示，电动汽车的引入有望改善空气质量。
Recently, Chinese megacities have suffered serious air pollution. Previous studies have pointed out that transportation systems have become one of the major sources of air pollution and on-road pollutant concentrations are significantly higher than off-road. Electric vehicle (EV) introduction is proposed as a method to alleviate the current situation. In order to better understand the benefit of the use of EVs in Beijing, a simulation platform has been developed to evaluate the improvement of air quality with the use of EVs quantitatively within the selected area. Four scenarios with different EV penetration rates are proposed and the results revealed 5%, 10%, 15% EV penetration rates which will bring about improvement of 0.86%, 9.01% and 12.23% for PM2.5, 0.92%, 9.01% and 13.32% for nitrogen oxides (NOx), 0.95%, 8.86% and 13.73% for CO, respectively. The results revealed a promising improvement of air quality with the introduction of EVs.
