About this role

Bachelor's or Master's thesis - Prototype Development of Detachable Cell Contacts for Pouch Cells (all genders) Darmstadt As electric mobility continues to expand globally, the repairability and recyclability of traction batteries are becoming increasingly critical. Current battery modules commonly use welded cell connections, which provide good electrical performance but make maintenance, repair, and recycling difficult: if a single cell becomes defective, the entire module often has to be replaced. At Fraunhofer LBF, we are therefore developing detachable and reusable cell contacting solutions that allow defective cells to be exchanged individually and simplify module disassembly at the end of life. The thesis focuses on the prototype development and experimental validation of an easily detachable cell contacting solution for pouch-cell battery modules. Based on the detachable cell contact concept selected in a previous thesis, a prototype module will be manufactured by additive manufacturing and conventional machining, assembled with the provided cells, and evaluated on the eMAST test bench under vibration and climate conditions as well as in a driving cycle including charging and discharging. The cells, additional components, and the complete test infrastructure are provided in-house. The test results will be analysed with regard to mechanical stability, contact reliability, and functional performance, and will contribute to more maintainable, reusable, and recyclable battery systems. Hier sorgst Du für Veränderung Manufacture a prototype using additive manufacturing and conventional machining methods based on the selected detachable cell contact design from the previous thesis Integrate the provided cells and additional required components into the module prototype Prepare and carry out tests on the eMAST vibration test bench in a climate chamber Perform vibration testing under relevant environmental conditions Conduct a driving cycle test including charging and discharging of the prototype Analyse the test results and assess mechanical stability, contact reliability, and functional performance Document the prototype development, test setup, results, and conclusions Hiermit bringst Du Dich ein Studies in Mechanical Engineering / Electrical Engineering / Mechatronics or related fields Interest in battery systems, experimental testing, and prototype development Basic knowledge of CAD Experience with testing or battery technology is an advantage Good command of English and German Was wir für Dich bereithalten Hands-on work on site in our battery and vibration test laboratories at Fraunhofer LBF in Darmstadt Please note: this is an unpaid thesis position An individually tailored task with plenty of creative freedom A highly topical and practically relevant research topic with direct relevance to the circular economy The opportunity to actively participate in an innovative and interdisciplinary project Insight into current developments in battery module design, detachable contacting, and vibration and climate testing Wir wertschätzen und fördern die Vielfalt der Kompetenzen unserer Mitarbeitenden und begrüßen daher alle Bewerbungen – unabhängig von Alter, Geschlecht, Nationalität, ethnischer und sozialer Herkunft, Religion, Weltanschauung, Behinderung sowie sexueller Orientierung und Identität.
