In this paper we investigate the charging coordination of battery electric vehicles (BEV) with respect to the availability of intermittent renewable energy generation considering individual real world driving profiles in a deterministic simulation based analysis, mapping a part of the German power system in 2009. We propose a price based charging approach, initiated by an aggregator, which combines numerous BEVs in his fleet in order to optimize the utilization of energy from renewable sources, here wind and solar, thus offering a renewable tariff to consumers. Our results show that a price mechanism based on the availability of renewable energy and the charging availability of the BEVs combined with a voluntary reduction of the individual charging power to 1 kW, can increase the share of renewable energy charged in a year from 53 % to 75 % as compared to no charging coordination under similar conditions. An additional average cost evaluation of the proposed renewable energy tariff shows that wind power can be competitive with conventional sources at the end consumer level, while enabling considerable carbon emission reductions.
