Abstract: Due to the growing greenhouse effect, reducing greenhouse gas emissions is becoming increasingly important. Electric Vehicles (EVs), thanks to their lower carbon footprint, therefore are seen as the mainstream transportation of the future. However, single charging mode cannot accommodate a large number of parallel EV charging requests with limited charging infrastructures. To guarantee the Quality of Experience (QoE) of the charging service, this paper proposes a hybrid charging management scheme, by facilitating stable and fast charging from plug-in charging and flexible charging from V2V charging. Here, an optimization objective, charging cost is introduced as an optimization indicator. It considers charging price, charging waiting time and charging energy, to jointly optimize EV charging in price–time–energy dimensions. Each influencing factor is assigned a value through the Analytic Hierarchy Process (AHP) to identify its importance for EV charging. Meanwhile, due to the high mobility of EVs, charging reservation (including arrival time, required energy) is introduced, to optimize the charging selection with accurate information. Simulation results based on the Helsinki road topology show that the proposed scheme flexibly utilizes both charging modes and guarantees QoE for EV charging, in terms of increasing average charging energy and reducing charging price and charging waiting time.
