不同类型车辆全生命周期碳排放对比分析

Comparative Analysis of Life Cycle Carbon Emissions of Different VehicleVehicles

通过对比燃油车、插电式混合动力车、纯电动车车辆全生命周期碳排放情况,分析不同类型车辆在原材料获取、生产阶段及使用阶段的碳排放,得到燃油车、插电式混合动力车、纯电动车在各阶段的碳排放增加或减少变化量,从而确认新能源车型碳排放的比较优势。对同款车型3种不同动力配置的车辆的碳排放进行计算分析得出,相较于燃油车、混合动力车,纯电动车在车辆使用阶段的碳排放量有较大幅度的减少,而在原材料获得阶段和整车生产阶段的碳排放量有所增加。

By comparing the carbon emissions of fuel vehicles,plug-in hybrid vehicles and pure electric vehicles in the whole life cycle,the carbon emissions of different types of vehicles in raw material acquisition,production stage and use stage were analyzed to obtain the change amount of carbon emissions increase or decrease of fuel vehicles,plug-in hybrid vehicles and pure electric vehicles in each stage,so as to confirm the comparative advantages of carbon emissions of new energy vehicles.In this paper,the calculation and analysis of gasoline cars with three different power configurations of the same model show that compared with fuel cars and hybrid cars,the carbon emissions of pure electric cars are significantly reduced in the vehicle use stage,while the carbon emissions of raw materials acquisition stage and vehicle production stage are increased.
