Estimation of Electric Vehicle's Crusing Range Based on Real-Time Links Average Speed
For the reasons of relative short cruising range and insufficient charging facilities, the use and promotion of electric vehicles (EV) is restricted. The estimation of cruising range is important for the EV drivers when selecting the travel route. Energy consumption for different running status is the prerequisite for estimation of cruising range. In this study, an energy consumption factor model is established, which is characterized with reflecting the impact of frequent acceleration and deceleration of urban road, and the input parameter is easily obtained from usual road traffic information system. The results show that the proposed model can predict energy consumption with high accuracy. Then based on real-time links average travel speed, this paper proposes a method of estimating the cruising range when EV travels on a planned route according to drivers demand.
