Diverse Influence Factors on the Range of Electric Vehicles

Electric vehicles of today can be designed with high efficiency drives and drivetrains. This means that the aerodynamic drag, the tire losses and auxiliary equipment have an increasing influence on the range of the vehicle. Moreover, the user will experience "his range" in a single direction from A to B, rather than averaged. The rolling resistance and the drag force are not constants but temperature dependent. Effects of wind, rain and altitude change are also evaluated. Such factors are not included in typical driving cycle tests, but are important for the real range of the vehicle.
