PhotoVoltaic EV charge station

Abstract

The Electric Vehicles (EV) realize the clean and environment friendly traffic. It is true if the EV-s is fuelled by renewable based electricity. One viable energy source is the small and medium scale PV systems. This paper investigates the different PV - EV charger combinations. The concentrated load generated by the EV chargers can overload the existing network or huge developments are necessary. We found that the daytime garage of the officers and employees a possible place where to charge the cars during the work time. If we do not want to cause an extra load we have to synchronize the load to the actual PV generation. An appropriate rule based charger control can schedule the charge service of the suddenly arrived mass of consumers. In Óbuda University we made several developments for the investigation of the charging process. © 2013 IEEE.
