Netzintegration von Elektrofahrzeugen in Deutschland

According to various studies, a strong market penetration of electric mobility is expected in the next few years. On the one hand, electric vehicles can contribute to achieve climate targets, but on the other hand, they can place a heavy burden on the power grid and have serious consequences, such as component overload and voltage instabilities, if they are charged in an uncoordinated manner. Proper grid integration of electric vehicles with a coordinated charging approach can minimize these negative impacts and brings about positive aspects, such as improving grid quality and integrating larger amounts of renewable energy. Taking into consideration the legal framework and the different requirements of network operators, vehicle manufacturers and owners, this paper compares different network integration techniques. It is concluded that a decentralized charging management approach, in which the vehicle owners themselves make the charging decisions, is a good compromise between the different parties and consequently the best alternative for the grid integration of electric vehicles in Ger-many. One aspect that needs further investigation is which is the best way to motivate vehicle owners to actively participate in a flexible charging management
