After a project term of 24 months, over 70,000 kilometres travelled and around 1,800 charging events, one of the key findings from the cologneE-mobil project is that electric vehicles can already be integrated into commercial vehicle fleets without any problems.
The results of the fleet trials and the accompanying research showed that the limited range of electric vehicles compared to conventionally powered types leads to no restrictions of any kind in everyday operation. In the case of 50 % of the urban trips, the daily power consumption was in fact only 4 kWh, meaning that with a battery capacity of 20 kWh there is not even any need to charge the battery every day. These results coincide with the wishes of potential customers, who would ideally like to charge their vehicle at home or at their place of work.
Extensive surveys of potential customers have shown that, in principle, they have a positive attitude towards electric cars. Key reasons for considering a purchase are environmental friendliness and independence from oil. In the area of urban delivery, analyses have shown that battery-powered electric vehicles are already an economically attractive alternative.
With the help of measurements and experiments on noise perception it was also possible to obtain empirical data to confirm the suspicion that electric vehicles are subjectively noticed less quickly. It was apparent, however, through a direct comparison with modern petrol vehicles with a similarly low level of noise, that innovative solutions will be necessary in this area in the future for more than just electric vehicles alone.
