混合动力汽车动力系统环境影响对比分析

Comparative Analysis of Environmental Impact of Hybrid Electric Vehicle Power System

本文主要运用生命周期评价法对目前市面上普遍使用的两套混合动力汽车动力系统(方案A、方案B)进行生命周期评价对比,从动力系统组装(包括原材料获取)、道路运输以及废弃三个阶段对两种动力系统进行比对分析,最后在保证使用条件的前提下选取最优。本文所研究的动力系统构成包括电动机、发动机和动力电池三个主要元件。综合结果显示方案A为最优选择。

This article mainly uses the life cycle assessment method to compare the two sets of hybrid electric vehicle power systems currently used in the market(Scheme A,Option B),from the power system assembly(including the acquisition of raw materials),to road transportation and disposal.The two power systems are compared and analyzed in three stages,and finally the best is selected under the premise of ensuring the conditions of use.The composition of the power system studied in this paper includes three main components:electric motor,engine and power battery.The comprehensive results show that option A is the best choice.
