The thematic volume provides contributions on trends in electric drive technology as well as a holistic system approach regarding electric drive systems. The hybrid vehicles offered by car manufacturers in the passenger car sector are currently only slowly being adopted in the market due to relatively high additional costs and comparatively few additional features. In the commercial vehicle sector, the parallel hybrid has mainly established itself for delivery vehicles, while the serial hybrid has become popular for city buses. In the passenger car sector, there is a noticeable trend towards plug-in hybrids. If an electrically driven front or rear axle is additionally integrated, an all-wheel drive function can also be implemented. If the range for fully electric driving is limited, for example, to the urban area of about 25 km, then size and costs remain manageable.
