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.
