DeMoBat

The aim of the joint research project DeMoBat is to contribute 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/manufacturing or, depending on the material, pre-sorted for recycling. Previous projects, e.g. "Ultra Efficiency Factory and Digitalization", have shown that economic efficiency and resource efficiency, however, require a (partially) automated solution.

To demonstrate 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 disassembly line for traction batteries at joint venture 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
  • Flexibilization of disassembly by using robot vision systems
  • Optimization of the disassembly sequence (Precedence Graph)
  • Removal of cooling water and gear 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.

Overall, the DeMoBat project positions itself at the center of the TU-Clausthal's "Circular Economy" guiding theme. www.tu-clausthal.de/universitaet/ueber-uns/leitthema-circular-economy

A project extension until June 2023 has been applied for.
