EV usage and city planning of charging station installations

Abstract

Electric vehicles (EVs) are becoming popular in the United States. Battery EVs, powered exclusively by electricity, draw more attention because they emit zero exhaust fumes, transfer energy efficiently and can be more economical compared with internal combustion automobiles. This paper presents a comprehensive analysis of the real-world charging, driving and energy consumption patterns of electric vehicles and charging stations deployed in a college town over a period of ten months. Data collection approaches include data from charging stations and from Nissan CARWINGS telematics services. Results indicate that most charging events last fewer than three hours and most battery EVs are used locally within Athens, GA. Based on this EV usage analysis, potential impacts of wireless EV charging stations as well as a list of practical factors are discussed when implementing wireless charging stations across the city.
