The diffusion of innovations is an important process and its models have applications in many fields, with particular relevance in technological forecast. The logistic equation is one of most important models in this context. Extensions of this approach as the Lotka-Volterra model have been...

Elektromobilität bietet große Potenziale zur Reduktion der verkehrsbedingten Treibhausgasemissionen und Erhöhung der Versorgungssicherheit, bedeutet aber auch Veränderungen in der Automobilbranche. In der Vielzahl der Entwicklungen und Ereignisse gehen häufig der Blick auf die wesentlichen...

Plug-in hybrid electric vehicles (PHEV) combine electric propulsion with an internal combustion engine. Their potential to reduce transport related green-house gas emissions highly depends on their actual usage and electricity provision. Various studies underline their environmental and economic...

Commercial passenger cars are often discussed as an early market segment for plug-in electric vehicles (EVs). Compared to private vehicles, the commercial vehicle segment is characterized by higher vehicle kilometers travelled and a higher share of vehicle sales in Germany. Studies which...

Der Wirtschaftsverkehr wird häufig als potenzieller Erstmarkt für Elektrofahrzeuge diskutiert. Der Anteil gewerblich zugelassener Fahrzeuge ist in Deutschland zwar bestandsmäßig gering (10%), bei den Neuzulassungen beträgt er jedoch rund 60 %. Zudem verhelfen hohe Fahrleistungen zu einer...

Electric vehicles (EVs) have the potential to reduce green house gas emissions from the transport sector. However, the limited electric range of EVs could impede their market introduction. Still some potential users are willing to pay more for EVs. The combined effect of these and other...

The future market diffusion of electric vehicles (EVs) is of great importance for transport related green house gas emissions and energy demand. But most studies on the market diffusion of EVs focus on average driving patters and neglect the great variations in daily driving of individuals...

The vehicle distances travelled by individual users can very strongly between different days. This is particularly problematic for electric vehicles since trips larger than the electric range clearly reduce the vehicle's utility. Here we estimate the number of days with driving distance larger...
