The aim of the research project MeRegioMobil is to efficiently integrate mobile electrical storage in vehicles by means of innovative information and communication technologies and their implementation as integrated concepts into the established energy system. For this purpose, a wide variety of usage scenarios concerning the mobility behavior is examined. In the context of MeRegioMobil, a research and demonstration laboratory is to be established, in which, besides of research in the context of the e-energy project MeRegio, especially concepts concerning “smart home & mobility” can exemplary be examined. In addition to its benefit for demonstration purposes the laboratory can be used to test technologies and services prior to their application in the model region. Furthermore, a fleet test in Karlsruhe is being planed. As not all of the developed concepts and methods can be tested on any amount of real participants in the course of the project, off- and online simulations are made in addition to laboratory experiments and field studies, thus allowing for the examination of scaling effects is possible (e.g. 1 million electric vehicles). A continuous evaluation intended during the entire course of the project. The project is lead by the EnBW Energie Baden-Württemberg AG, at the KIT members are the AIFB, IIP, IISM, ITM, ZAR, DSN, ITI and IPD are involved.
