Abstract

Electric vehicle (EV) use has been focused to reduce the amount of environmental emissions from private vehicles. However, the driving range of EV is much shorter than that of gasoline vehicles, because of the low capacity of battery. Our objective is to quantitatively estimate the risk of incurring an empting EV battery under the use of daily activities. A couple of surveys are conducted to investigate daily vehicle use, under the different usage environment. The questionnaire survey included the following items; a plan for vehicle use in tomorrow, and the actual vehicle use in today. A trajectory-monitoring survey using a Global Positioning System is conducted to collect a precise distance. We developed an energy consumption model based on a survival duration model, considering household, dominant vehicle user, and residential characteristics as covariate. The estimated model can give us a quantitative evaluation about the required driving range of EVs in daily vehicle use.
