基于生命周期评价纯电动中型货车环境排放研究

Study on Environmental Emission of Pure Electric medium truck based on Life cycle Assessment

文章基于Ga Bi建模软件对某款纯电动中型货车构建了评价模型,利用此模型分析了该纯电动中型货车各生命周期阶段的排放,并获取了全生命周期的排放结果。研究结果表明:在全生命周期过程中,使用阶段的排放物最多,且主要污染排放物为CO、NO_X和SO_2。虽然纯电动汽车在使用过程中不会产生污染,但由于我国电力供给中大部分是火力发电,在产生电力的过程中,会有大量污染物排放;因此,改善电力供给结构,利用可再生能源发电,对于纯电动车辆的降排也有着重要意义。

In this paper, we based on the GaBi modeling software, the evaluation model of a battery electric medium truck is constructed. By using this model, the emission of all the life cycle phases of the Pure electric medium truck is analyzed, and the emission results of the whole life cycle are obtained. The result of research shows that: in the whole life cycle, the emissions in the use phase are the most, and the main pollution emissions are CO, NOX and SO2. Although Battery Electric Vehicles will not produce pollution in the use process, there will be a large number of pollutants discharged in the process of generating electricity because most of the power supply in our country is thermal power generation.Therefore, improving the power supply structure and using renewable energy to generate electricity is also of great significance for the emission reduction of pure electric vehicles.
