摘　　要：面对近年来全球日益凸显的能源危机与环境问题,我国正在大力推进汽车电动化进程。在双碳目标的推动下,国内新能源汽车市场增长迅速,全年销量或突破300万辆。与传统燃油车相比,纯电动汽车(Battery Electric Vehicle,BEV)生命周期碳排放水平更低,是汽车行业低碳发展的重要技术路线之一。本文从纯电动汽车碳排放量的主要影响因素出发,重点分析车辆行驶里程、电网清洁化、能耗水平、电池能量密度、可再生材料利用率这5个影响因子与碳排放量的相关性,并对纯电动乘用车的减碳途径提出发展建议。With the ever increasing energy crisis and environmental issues globally in recent years,China is enhancing the processes of automobile electrification.Driven by the double carbon targets,China new energy vehicle market is growing rapidly,and the annual sales volume may exceed 3 million units.Compared with traditional fuel vehicles,Battery Electric Vehicle(BEV)has lower carbon emission level during the whole life cycle,which is one of important technical routes for the low-carbon development of the automotive industry.Based on the main influencing factors of carbon emission for BEVs,this paper focuses on the correlation between the 5 influencing factors and carbon emission,including vehicle mileage,power grid cleaning,energy consumption level,battery energy density and utilization rate of renewable materials,and proposes development suggestions for carbon reduction ways for BEVs.
