Axel Kagerer, plant manager at Siemens AG in Regensburg, and Christian Albrecht, head of product management at Siemens in Regensburg, visited the lab. They were welcomed by Prof. Dr. Rainer Holmer, dean, and laboratory managers Prof. Bernhard Hopfensperger and Prof. Thomas Kühner. Günther Dürrmeier, 2nd chairman of the IG Historische Straßenbahn Regensburg (Regensburg Historical Tram Association), took part in the exchange on behalf of the association.
From overhead lines to batteries
The Regensburg tram operated in the city until 1964. Today, a restored motor car and a trailer car still exist. The aim of the current project is to equip the historic motor car with a battery-electric drive system, thereby rethinking a piece of Regensburg's city history from a technical perspective.
Since 2020, students from various degree programmes have been developing a powerful drive system as part of their project and final theses. The work includes the development and optimisation of power electronics and their integration into compact control cabinet solutions.
Technical exchange in the laboratory
During the meeting, guests were given an insight into the current state of development. The laboratory prototype was presented, along with key technical issues relating to battery-electric drives. The event served as a platform for technical dialogue between the university, industry and the association. The focus was on technical requirements, possible solutions and the exchange of expertise from research and practice.
Project work in the laboratory will continue at the start of the 2026 summer semester. Students will once again be actively involved in the further development of the system.
