In contrast to fuel vehicles, the wide-spread use of electric vehicles (EVs) is still hindered by limited battery capacity and cruising range. It is important to forecast the EVs cruising range accurately before departure and reduce the risk of running out of electricity before arriving at the destination or charging station. In this article, through analyzing the variation characteristics of energy consumption rate with instantaneous speed and acceleration, a series of EV energy consumption rate models are established according to different operation modes. Further, a novel cruising range estimation method is proposed based on the presented EV energy consumption rate models, which is characterized by fully considering the impacts of instantaneous speed and acceleration. Finally, using the simulation data of a road in Beijing, the model presented in this article is utilized in conjunction with microscopic traffic simulation technologies to demonstrate its application in estimating the EVs cruising range under different traffic volumes.
