混合动力汽车全寿命周期成本计算模型及分析
摘要：为了定量分析混合动力汽车(hybrid electric vehicle，HEV)的环境效益和全寿命周期内的综合成本，首先，从外部环境成本和直接经济成本两个方面，分析了HEV全寿命周期成本的构成;在此基础上，分别建立了混合动力汽车的外部环境成本模型和直接经济成本模型;从车型和时间两个维度，提出了基于分步叠加思想的计算方法;最后，通过算例，将混合动力汽车的环境和经济效益与传统汽车进行了对比，并就能源价格和碳排放价格对HEV的影响做了敏感性分析。结果表明，在设定条件下HEV全寿命周期成本要低于传统汽车，发展HEV符合经济性和可持续性要求。
Abstract:To quantify the environmental benefits of hybrid electric vehicles and comprehensive cost in total life cycle, the structure of total life cycle costs of hybrid vehicles is put forward from two aspects, the external environmental cost and the direct economic cost of hybrid vehicles. Base on this, an external environmental cost estimation model and a direct economic cost model of hybrid vehicles are established respectively, in which a superimposed step by step calculation method is presented from two dimensions of vehicle type and time. In the end, the environmental and economic benefits between hybrid vehicles and conventional cars are compared by an example, and the sensitivity on energy price and carbon price is analyzed. The results show that the life cycle cost of the hybrid vehicles in specific conditions is lower than that of conventional cars, and the development of hybrid electric vehicles meet the economy and sustainability requirements.
