flexible, responsive, renewable, efficient e-buses - FreeE-Bus


In public transport, many diesel buses are to be replaced by e-buses. However, large-scale operation of e-bus fleets is still untested. The project collects measurement data and IT framework conditions of the charging infrastructure as well as experiences and needs in the Lake Constance area to develop an optimized charging management. An optimization model creates control signals for the e-buses and the charging infrastructure based on current timetable, weather, and energy grid information.

Project Objective

In the project, an optimized charging management system for e-buses in public transport in the Lake Constance region will be developed. In the process, optimal charging curves are created from the determined parameters of the technical infrastructure as well as from current system information. Sustainable, cost-efficient and flexible charging management is intended to support the transformation of public transport, which is still powered by fossil fuels, to climate-friendly e-mobility. At the same time, the cross-national transfer of knowledge is to be promoted.

Support Program

This project is carried out with funding from the interreg VI program Interreg Alpenrhein-Bodensee-Hochrhein, which is co-financed by the European Regional Development Fund
