Over the last few years, electric mobility has once again been the subject of lively discussions due to new, more powerful rechargeable batteries and the high volatility on the oil markets. Political objectives such as a reduction on the dependency on oil, more efficient energy transformation, significant CO2 reductions and a reduction of local emissions from transport are important drivers of electromobility. Electromobility is therefore a prominent topic in environmental, economic and social terms. Many challenges still have to be solved with regard to technology and infrastructure. Also, suitable business models have to be developed, and needs and preferences of users have to be taken into account for electromobility services to be successfully diffused and used. Policy support can make a decisive contribution for a solution of these challenges. Electromobility has already been promoted by the German government in numerous research programmes and pilot projects. These support programmes and projects tackle different questions and consider different applications and aspects of electromobility. So far, there has been no comprehensive collection of currently available results. Because of the complexity of the topic, however, such an overall picture is essential for a wide-ranging discussion and evaluation of electromobility with regard to ecological, economical and social aspects and for any decision about political objectives and measures in this context.
