An optimal local charging strategy for competing electric vehicles on quick charging facilities

Abstract

Electrification of Transportation is seen as a sustainable way for future mobility. Electric vehicles (EV) play therefore a substantial role, and are strongly supported for their market appearance while at the same time, they pose substantial challenges for the electric grid infrastructure. In contrast to the current gasoline fuel stations, electric charging stations do depend on the conditions of the power grid they are connected to. Based on the generation profile, these conditions vary regarding the provided power level. We present an approach for dynamic on-site reservation (locally on a single charging station) for instant charging needs increasing the efficiency and exploits the local quick charging capacities for the charging station owner and the conditions of the power grid. Results show an optimized usage of the available power resources of the station, as well as an increase in the number of EVs that can be served.
