基于全生命周期成本理论的六种能源类型城市公交的经济性对比分析

Economic Comparison and Analysis of Public City Buses of Six Energy Types Based on Life Cycle Cost Theory

以燃油、CNG天然气、LNG天然气、气电混动、纯电动、氢燃料六种类型城市公交作为研究对象,采用全生命周期成本理论法对其经济性进行对比分析,建立了以上六种类型城市公交的全生命周期的成本计量模型,对初始购置成本、使用成本、维修保养成本、报废收益、生命周期总成本进行了差异分析。结果表明,纯电动公交的全生命周期成本最低,具有明显的经济性优势,同时符合国家节能减排和蓝天保卫战的需求,是目前最为理想的公交类型。

Taking city buses with fuel,CNG,LNG,gas-electric hybrid,pure electric and hydrogen fuel as the research object,this paper compares and analyzes their costs based on the life cycle cost theory,builds the cost model for the life cycle of the above six types,and gives a comparison and analysis on their initial acquisition costs,usage costs,maintenance costs,scrap benefits and life cycle costs.The result shows that pure electric bus has the lowest life cycle cost,obvious economic advantages,and meets the needs of national energy conservation and emission reduction in blue sky defense war,so it is the most ideal type of public city bus at present.
