Research on the Optimum Continuous Mileages under the Pure Electric Mode of Plug-In Hybrid Electric Vehicles

Abstract

Plug-in hybrid vehicles (PHEVs) combine the motor and traditional internal combustion engine with their full advantages, they have great advantages in practical application, are an important direction to develop the energy saving and emission reduction vehicles. The PHEVs’ capacity of battery pack determines the continuous mileages under the pure electric mode, the larger the capacity of battery pack is, the higher the PHEVs’ cost is. But the continuous mileages under the pure electric mode are longer, the fuel cost of consumers is lower. For ordinary consumers, economy and utility are two important factors to purchase PHEVs. Considering different consumers, city forms and people use habits, the PHEVs’ optimum continuous mileages under the pure electric mode for suitable promotion were presented, to make they have the optimum consumer ownership cost, have the important practical significance to promote the development of PHEVs in different area.
