Study on Life-Cycle Energy Impact of New Energy Vehicle Car-Sharing with Large-Scale Application

Abstract

Based on the life cycle assessment theory, the system of energy impact assessment is established relying on the demonstration project of new energy vehicle (NEV) car-sharing in Wuhan, Hubei province in China. The energy impact caused by NEV car-sharing is quantitatively analyzed. The results show that the NEV car-sharing business model needs to meet some operating conditions to obtain energy benefits. According to the operation scale of 3,000 vehicles, this demonstration project will lead to a decrease of annual gasoline consumption by 1,853t, while the power consumption will increase by 3.36GWh. The key factors affecting the energy benefit of NEV car-sharing include the average daily mileage of vehicles, energy consumption per 100km, operation period, vehicle class, power grid structure, and other aspects. Operators can improve energy benefit from two aspects: vehicle model selection (Class A0 and Class A00 should be preferred) and operating intensity (increasing the average daily mileage and operation period).
