DeMoBat

The aim of the joint research project DeMoBat is to make a contribution to increasing sustainability and securing economically strategic raw materials in the field of e-mobility. To this end, Li-ion traction batteries and e-drive units are dismantled for reuse/remanufacturing or, depending on the material, pre-sorted for recycling. Previous projects, e.g. "Ultra-efficient factory and digitalization", have shown that cost-effectiveness and resource efficiency require a (partially) automated solution.

In order to show the feasibility of automated disassembly of complex assemblies, four demonstrators are being developed and tested as part of the project. Three of these demonstrators represent the dismantling line for traction batteries at joint partners. The fourth demonstrator developed by CUTEC tests the industrial disassembly of e-drives.

The main focal points of the work are

• Design and control of the robot arms
• Making disassembly more flexible through the use of robot vision systems
• Optimization of the disassembly sequence (precedence graph)
• Removal of cooling water and transmission oil residues
• Design and manufacture of disassembly tools
• Development of camera and sensor-supported success control systems

Furthermore, obstacles to automated disassembly are to be identified and an optimized design for recycling derived from this.

Overall, the DeMoBat project is positioned at the center of the TU Clausthal's key topic "Circular Economy". Link: https: //www.tu-clausthal.de/universitaet/ueber-uns/leitthema-circular-economy

A project extension until June 2023 has been applied for.
