How and where does (flexible) charging and discharging of electric vehicles take place?

One of the main research areas in mobility is the modeling and evaluation of different charging strategies for electric vehicles. Based on traffic surveys, user-group-specific driving profiles are modeled or measured. Based on this, various charging strategies are evaluated concerning their economic and ecological efficiency in an energy system increasingly based on renewable energies. Examples of ossible charging strategies are uncontrolled charging, self-consumption-optimized charging (PV self-consumption), price-optimized charging, emission-optimized charging, or combinations thereof. Likewise, bidirectional vehicles are considered.

The models allow analyses of single vehicles and different pool sizes with corresponding prioritizations.

In particular, we consider the following questions:

• Where will charging occur in the future (at home, at work, in public)?
• What types of charging controls are available?
• How many charging stations are there in Germany?
