Analysis on the Influencing Factors of Driving Mileage of Electric Vehicles: A Case Study of Taxis in Beijing

Abstract

With the seriousness of energy and environment problem, the electric vehicle (EV) has been widely used. However, the low endurance mileage limits the popularization of electric vehicles (EVs). The aim of this work is to study the influencing factors of driving mileage and then take appropriate measures to extend it as possible. In this paper, the influencing factors of driving mileage are discussed based on the operation data of electric taxis monitored by the Electric Vehicles Monitoring and Service Center of Beijing (EVMSC). The results illustrate that the driving mileage is maximum when the ambient temperature is around 20°C, which will decrease with temperature rising or dropping. Furthermore, the aggressive driving behaviors will increase the consumption of energy and decrease the driving mileage. Lastly, the driving mileage increases with the increase of charging frequency and charging capacity. The conclusions of this work can give EV drivers of EVMSC driving instructions to help them reach the next charging station or the destination in safety and in time.
