Environmental Impact And Life Cycle Cost Analysis Of New Energy Vehicles And Traditional Fuel Vehicles

As a strategic substitute for traditional fuel vehicles,new energy vehicles enter the market with the core purpose of reducing the terminal energy consumption and environmental impact.In recent years,many scholars have studied the environmental impact of new energy vehicles and traditional fuel vehicles,which ignores the life-cycle cost of vehicles.With the diversified needs of the society,it is no longer possible to evaluate the automobile only from the single Angle of environmental impact.In this context,based on the previous research results of scholars,this paper proposes a method combining life cycle assessment with life cycle cost theory to evaluate the automobile from the perspectives of environmental impact and life cycle cost.This paper based on the life cycle assessment method,systematically analyzes the electric cars,hydrogen fuel cell vehicles and traditional fuel vehicle life cycle environmental impact,then based on the theory of life cycle cost automotive life cycle cost model is set up,choose three kinds of automobile market sales of the highest models empirical research,this paper discusses the background of regional policy incentives under car cost difference,and select the key factors in the sensitivity analysis.It is found that（1）in the complete life cycle,the environmental inventory of new energy vehicles has significant advantages.The energy consumption,CO₂emission and conventional pollutant emissions of new energy vehicles are all lower than that of traditional fuel vehicles,but particulate matter emissions are higher than that of traditional fuel vehicles.The environmental impact index of new energy vehicles is better than that of traditional fuel vehicles,and the environmental index of hydrogen fuel cell vehicles is better than that of electric vehicles.（2）in terms of life cycle cost,new energy vehicles perform better than traditional fuel vehicles,but the explicit cost of the former is generally higher than the latter.New energy vehicles in first-tier cities have an absolute cost advantage.Providing government subsidies,reducing battery costs and extending life cycle mileage are critical to reduce the explict life cycle costs of new energy vehicles.
