Elektromobility at the Ruhr-University Bochum

Bus - train - car - e-car - bicycle - on foot: intermodal transport

Intermodal mobility and electromobility are two essential elements for the intended change in transport, towards ecologically sustainable mobility. However, these forms of mobility are currently usually associated with high planning effort, restrictions and uncertainties for users. Another disadvantage of e-vehicles for many users is their cost-effectiveness. The project interflexibEl uses a cloud-based data management system (CDMS) to interconnect and evaluate offers from various mobility providers (including public transport, car and bike sharing providers) as well as real-time data from carriers, the charging infrastructure and, if necessary, your own e-vehicle. For the user, intermodal mobility-planning is simplified by the CDMS calculating mobility solutions based on the appointments entered in the user's own calendar and individual preferences and requirements, displaying them via a smartphone app and controlling the charging process of the e-vehicle.

Many people are not quite certain if an electric car would fit into their everyday life. A new smartphone app might help with this issue

A new app helps drivers decide if switching from a petrol-driven car to an electric car is a viable solution for them – and which vehicle model would be best suited to their individual requirements. It was developed by engineers at Ruhr-Universität Bochum under the auspices of Prof Dr Constantinos Sourkounis. Using the smartphone app, drivers can record typical routes. Based on the gathered data, the program generates a list of vehicle models that would meet the driver’s requirements, for example cars with sufficient range. Information pertaining to cost saving can also be provided.

Also available as web application

People who do not own an Android smartphone or a car can access a simplified, gratuitous version of the service online. There, users can enter typical route data to generate information similar to those supplied by the app.

If you are interested in supporting the development of the apps or in linking the suggested vehicles with your offer, please feel free to contact us. Of course, also other ideas are welcome.



Individual and adaptive technologies for connected mobility - this is the motto of the project interflexibEl, which aims at the optimal combination of means of transport. We want to obtain a clear overall picture of people's mobility in everyday life and rely on your opinion. Make a valuable contribution and support our research by participating in our survey.

Project logo - EValuation


In the web-application you can input your frequent trips and find out, which electric vehicle can satisfy your demand best.

Android Application

The android application allows you to record your trips and suggests full electric and plug-in hybrid electric vehicles which satisfy your demand. In addition, a comparison of costs with your own conventional vehicle is possible. All available and suitable vehicles are suggested in the evaluation with extensive information. Moreover, special details can be illustrated for every recorded trip, e.g. the estimated state of charge of the battery. Finally you have the chance to receive an offer for a selection of vehicles without obligation.
