E-Mobility is gaining more and more attention and importance not only for researchers but for all community members. Therefore the German government presently supports several projects on E-Mobility with a total funding of about 500 million Euros. Preliminary results of one of these projects are presented in this paper. The main focus is a field test on vehicle to grid communications, ICT-Solutions and business models. To support a vehicle to grid communication a roaming concept was developed. An ICT-Solution called Energy Name Service (ENS), enabling the identification and providing the functionality to retrieve additional sources of information on vehicles to grid is specified below together with two new E-Mobility-specific ID types. Preliminary results of an E-Mobility car-pooling field test using an ICT-System with an intelligent control prediction algorithm show important factors for future E-Mobility business models. They are currently under development in order to help accelerating market launch.
