电动汽车碳排放计算与跟踪评估的探讨

The Discussion of Calculation Method of Electric Vehicle Carbon Emission and Tracking Evaluation

电动汽车作为新能源的交通工具给人类社会提供新型驱动动力,同时减少二氧化碳排放;但电动汽车在制造以及使用过程中排放了多少二氧化碳,不同型号与驱动性能各异的电动汽车碳排放量能否到达国家碳排放减排要求?首先我们计算传统汽车与电动汽车的100公里碳排放,合理评估电动汽车使用中的碳排放,最后推导出一个电动汽车碳排放与跟踪评估公式;这一公式引入一个可再生能源用电系数,通过公式对比纯电动汽车与HEV在生命周期结束时二氧化碳排放情况。电动汽车能效的提升,充电电能来源追踪,这都需要综合考虑,以上可指导电动汽车类型选择及使用过程中碳跟踪与评估。

As a new energy vehicle,electric vehicle provides new driving force for human society and reduces carbon dioxide emission at the same time;however,how much carbon dioxide is emission in the manufacturing and use of electric vehicles,whether electric vehicles with different models and driving performance can be fulfill with the national carbon emission reduction requirements.Firstly,we could calculate 100 kilometer carbon emission of fuel automobile and electric cars,further reasonably evaluate the carbon emission in using of electric cars.Finally,we deduced a formula for carbon emission and tracking evaluation of electric cars;The formula introduces a power consumption coefficient of renewable energy.Through this formula,we knew the result of comparing the carbon emission of pure electric cars with HEV at the end of life.The improvement of energy efficiency of electric cars and the tracking of charging power sources need to be comprehensively considered,These could guide type choosing of electric vehicles and the carbon tracking and evaluation in use of electric vehicles.
