Thesis "Optimization of a Sorptive Dry Air Supply for Battery Cell Production"
The Fraunhofer Institute for Solar Energy Systems ISE, based in Freiburg, plays a leading international role in the field of renewable energy systems and technologies with its research and development work. Securing the livelihoods of current and future generations as well as preserving our natural environment drive our efforts. With our currently around 1,400 employees, we are shaping the transformation of energy supply through outstanding research results, successful projects with industrial partners, spin-offs, and global collaborations – towards the exclusive use of renewable energies. For our team “System Integration and Energy Concepts”, we are looking for a student assistant to start as soon as possible, with the opportunity to write a bachelor's, diploma, or master's thesis. One of our projects, funded by the Federal Ministry of Education and Research, focuses on the energy-efficient production of battery cells. The goal of the project is to design a controlled production environment that surrounds the manufacturing processes with the smallest possible volume while meeting both cleanroom and dry room requirements. To meet these requirements, very low residual moisture levels are necessary in the controlled manufacturing environment, as higher levels would otherwise impair the future storage capacity of the battery cells. Therefore, sorption wheels are used for dehumidification, which require enormous amounts of energy for regeneration. To reduce this energy consumption and therefore the CO₂ footprint of the produced batteries, we are investigating the operation and interconnection of the sorption wheels using a numerical simulation model in Modelica/Dymola. We are optimizing the processes according to the given requirements. The aim is to develop a parametrizable universal model based on various created models that achieve the target dew points of up to -30 °C. Using discrete and continuous parameters, this model should find the optimal parameter set via a “Functional Mock-up Interface” (FMI) with an algorithm to be implemented in Python.
