Empirical Study of Using Renewable Energies in Innovative Car-Sharing Business Model "in Tandem" at the University of Hildesheim.

The renewable energy is becoming an integral part for the electric vehicle charging station to reduce greenhouse gases. The combination of this clean technology with appropriate business models reinforce the positive impact on the environment. In this paper we present empirical study of photovoltaic charging system used in a new car-sharing business model "in Tandem" implemented at the University of Hildesheim under the project name e2work. The data analyzed from photovoltaic (PV) over the period of one year, exhibits an interesting insight into the renewable energies supply of electric vehicles under preset conditions of the business model and thus helps to dimension an appropriate size and storage capacity of a photovoltaic system considering different weather conditions and mobility demands. It ensures the quick transferability and easy implementation of both the business model and the appropriate infrastructure to any place.
