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
