Grid integration of electric vehicles considering the mobility needs

Battery electric vehicles combined with renewable energies have a huge potential to reduce CO2- emissions, especially in the field of motorized individual transport. However, a future change from combustion engines to electric drives leads to new problems and challenges. From the perspective of energy engineering, among others, the following questions arise:
• Where should be charging infrastructure for electric vehicles created?
• Which connection power should be provided?
• How big is the additional grid load?
• What must be done to prevent overloading?
These questions are dealt with in the Austrian research projects “Smart Electric Mobility” and “V2G - Strategies” with national partners from academia and industry (funded by the Austrian Climate and Energy Fund, programme “New Energy 2020”). The methods and selected results are presented in this paper.
