Summary

How can long-range capability of e-vehicles be achieved? The decisive factors are the price, the range and the speed, respectively the time of travel. This paper will show solutions aimed at obtaining improvements in all areas. Of course, the battery is at the centre of such discussions. Several different measures will be proposed to provide technically optimum and cost-effective solutions for the integration of the continuously developing cells. They result in a battery pack for use in electric vehicles with a height of just 80 mm. A further critical element regarding long-distance e-mobility is fast charging, whereby voltage levels of 800 to 1000 V are expected in the near future. This is the only way to achieve the expected charging performance and charging time. This also has other positive effects on the vehicle. Considerable improvements in the efficiency of the e-powertrain will be achieved in the future through the introduction of silicon carbide based power electronics. The climate control of the vehicle’s passenger cabin, as the most important energy consumer outside of the powertrain, will also be discussed, where an intelligent selection of technologies can enable significant energy savings and hence range extension in real conditions.
