Analysis of current patterns of private car usage shows that everyday journeys can generally be handled without any problem by a purely electric vehicle. Less frequent long journeys, on the other hand, represent the greatest problem. In the relevant »mini« to »compact« segments, long distances were only possible in up to 13 % of cases using a battery-powered electric car without alternative mobility options. The potential in commercial vehicle fleets is between 53 % and 81 % depending on the segment. The theoretical total potential for battery-powered electric cars in Germany is around 4 million vehicles.
Over 30 fleet operators were surveyed on the suitability and acceptability of electric vehicles. The results show that the most important procurement criteria are purchase and operating costs. Companies that attribute a high level of importance to the environmental characteristics of their fleet and a »green« company image would accept a cost premium of 10–20 %.
The electricity demand was portrayed on a precise hourly basis for various scenarios based on typical private and commercial car usage patterns. The results show that the total electricity demand through to 2030 is relatively low. However, without any system of charge management new load peaks could occur sooner. Furthermore, while simulations show that electric vehicles may in future become so-called »flexible consumers« of temporary excess renewable energy, their power demand, however, will not be sufficiently or completely covered in this manner.
