Political action supports the built-up of public charging infrastructure to increase market shares of battery electric vehicles (BEV). For a cost-effective deployment of public charging infrastructure, a detailed knowledge of charging infrastructure needs is necessary. However, the effect of increased vehicle ranges on charging infrastructure needs is not yet sufficiently understood. The aim of the present paper is to determine the number of fast charging points needed in Germany for different ranges of BEV. We use information on daily driving distances of real-world driving data from 6,339 German conventional passenger cars to deduce yearly charging demands for different ranges of BEV. Finally, we determine fast charging infrastructure needs in Germany by combining a coverage-oriented with a demand oriented approach and take differences in local charging demands into account. For Germany, we find that 500 fast charging points could meet charging demands of up to 500,000 BEV. In addition, we see charging demands decreasing with higher vehicle ranges as the resulting effect of a lower number of charging events on charging infrastructure needs outweighs the effect of increased charging times per charging event.

Potential users of plug-in electric vehicles often ask for public charging facilities before buying vehicles. Furthermore, the speed of public charging is often expected to be similar to conventional refueling. For this reason, research on and political interest in public charging focus more and more on fast charging options with higher power rates, yet estimates for future needs are rare. This paper tries to fill this gap by analyzing current charging behavior from a large charging data set from Sweden and Norway and take the findings to calibrate a queuing model for future fast charging infrastructure needs. We find that the ratio of battery electric vehicles to public fast charging points can be similar to other alternative fuels in the future (close to one fast charging point per 1000 vehicles for high power rates of 150 kW). In addition, the surplus on the electricity prices for payoff is only 0.05–0.15 €/kWh per charging point. However, charging infrastructure needs highly depend on battery sizes and power rates that are both likely to increase in the future.
