Presentation of the research project eLab
Motivation and Introduction of eLab
The eLab explores the electro-mobile production process, from development to production. It represents two areas of expertise, in which development and production processes can be explored and optimized. In eLab the manufacturing processes of the battery and the electric powertrain can be analyzed in a real production environment. In addition to the automation of production and research of engineering systems and prototyping is the efficiency of the processes in the foreground
Objectives of eLab
- Support through expertise and construction of a comprehensive infrastructure for the development of electric vehicles to series production.
- eLab as a point of contact for companies in the development of electric vehicles and their components.
- Project-related and cross-project collaborations are possible.
- Laying the foundation for the series production of electric vehicles through a highly sophisticated development environment for battery and drive train components.
Research and Development in the Following Areas
- Battery production: Shuffle, coating, formation & aging, cell contacts, pack assembly
- Rotor Assembly: Gluing and assembling with magnets, heating of the rotor core, joining the rotor shaft, balancing, cleaning, magnetizing
- Stator: The stator winding, impregnation, interconnect
- Final assembly: Heating the housing, joining of housing and stator, joining of the bearings on the shaft, joining of the rotor in the stator assembly of bearing shields and seals, end-of-line test, rework

PEM Cell Manufacturing
The cell production of the PEM at RWTH Aachen University concentrates on the industry-oriented production of current and future battery cell technologies. The aim here is to achieve the most flexible, cost-effective and resource-saving production possible. To this end, various solutions are being pursued.
One concept is the so-called "mini-environments". Instead of a conventional clean room or dry room, which due to its dimensions entails enormous operating costs, the PEM manufactures in miniature clean rooms that are exactly as large as the respective process requires. This means that each system is encapsulated separately and connected by sluices. Thanks to automation, which is currently being implemented, the processes are just as powerful as comparable processes in conventional clean rooms. In addition, they can be used to process novel battery cell technologies with industrial processes that require an inert gas atmosphere.
PEM cell production develops new process solutions for new battery technologies in order to transfer them into industrializability. In addition, research is being conducted into which process synergies between battery and fuel cell production can be industrialized and thus made economically viable.
The data required for this is collected using IoT applications. The IoT applications are provided and further developed by several industrial partners. This enables data to be read out and visualized in real time, so that processes can always be optimally controlled in order to achieve industry-oriented and reproducible cell production.
