Abstract: With the deepening development of China's energy conservation and emission reduction policies and the continuous improvement of new energy vehicles, the proportion of plug-in hybrid electric vehicles in the entire new energy vehicles is expected to further increase to 41%. This paper analyzes the current development of plug-in hybrid electric vehicles, and gives a simplified cost analysis model under the whole life cycle scenario. At the same time, based on the scenario of plug-in hybrid electric vehicles with different battery capacities, the cost difference of the whole life cycle is analyzed, and the influencing factors of the cost of plug-in hybrid electric vehicles under different daily use conditions such as the change of battery capacity cost, different charging modes and oil price are analyzed. The optimal and economical purchasing choice of plug-in hybrid electric vehicle in the whole life cycle scenario is given.

Key words: plug-in hybrid electric vehicle; the whole life cycle; battery costs; charging mode; oil price

摘要： 随着中国节能减排政策的深化发展和新能源汽车的持续提升，插电式混合动力汽车在 整个新能源汽车中的占比有望进一步提升到 41%。文章对插电式混合动力汽车当前发展情况 进行分析，给出全生命周期场景下的简化成本分析模型。同时，基于插电式混合动力汽车配 置不同电池容量场景下进行全生命周期的成本差异分析，分析电池容量成本变化、不同充电 模式和油价变化等日常不同使用情况下插电式混动汽车成本的影响因素，针对性地给出插电 式混合动力汽车在全生命周期场景中最优经济的购置选择。
