Technology Transfer Center for Electric Mobility Würzburg-Schweinfurt begins work

The first theses in the field of battery systems were defended in Barcelona

In the Technology Transfer Center for Electric Mobility (TTZ-EMO) of the Technical University of Würzburg-Schweinfurt (THWS) For the first time, two employees have been able to obtain collaborative doctorates in the Spanish language Universidade Politecnica de Catalunya Obtaining a Ph.D. in Battery Systems. Scientific staff Dr. Andreas Ziegler of Essleben and Dr. David Oeser from Unterspießheim wrote their theses in the years 2019 to 2022 and successfully defended them in Barcelona at the end of October 2022 with a first mark “with excellent distinction”. On January 10, 2023 they received written consent to use the title of Ph.D.

The two new doctors, who received their master’s degrees from the Würzburg-Schweinfurt University of Applied Sciences (FHWS) in 2017, have spent several years researching various topics related to battery life. For this purpose, David Oeser examined the depth of parameter variation of battery cells. Through a complex series of tests, he was able to identify the causes of deviations between individual cells of an aging lithium-ion battery, thus offering manufacturers and end users new options for extending battery life in the future.

With the help of the active battery management system he developed, Andreas Ziegler was able to show the opportunities and limitations in extending the service life and increasing the efficiency of lithium-ion batteries. Through extensive long-term testing that lasted several years, he demonstrated the advantages and disadvantages of complex balancing algorithms. Both works contribute to a better understanding of the use of modern battery systems and to make them safer, more efficient and longer lasting.

Supervising the worlds Daniel-Montesinos-Mircale at Universidade Politecnica de Catalunya (UPC) in Barcelona, ​​who served as PhD supervisor, together with TTZ-EMO Institute Director Professor Dr. Ansgar Akva accompanied Ph.D. Daniel Montesinos was particularly impressed that both PhD students did not lose focus during the COVID-19 pandemic and continued to develop their work in a slew of online meetings. Director of the Institute, Prof. Dr. Akva praised the excellent work done by his staff, who also agreed to stay at TTZ-EMO and would thus open up many other perspectives for the Institute. This and other research work of THWS will be augmented by an additional Professor of Battery Systems starting in March 2023.
