Concept development for a steel-intensive circular and modular design of BEVs

The aim of this research project is to make use of the advantages of a modulary manufactured design in terms of sustainability and circularity. The project will develop concepts for functionally integrated modulary manufacutred steel designs in combination with design for disassembly approaches for sustainable and energy-efficient production, usephase, and recycling. The joint project consists of three interdisciplinary subprojects.

Subproject 1 (ika): Development of a circular vehicle concept in steel-intensive modular design - KoZiMo Vehicle: The first subproject aims at the constructive and requirement-oriented design of steel modules to be used and their integration into a full vehicle. To this end, the requirements of future body concepts in production will first be analyzed with a focus on sustainability. When integrating them into the full vehicle, the focus will be on the dismantlability and efficient replacement of modules in existing car bodies. Structural simulation and numerical optimization will be used to identify potential improvements and examine them with a focus on crash safety. The increase in sustainability of the concept to be developed will be evaluated with the help of a life cycle assessment (LCA).

Subprojects 2 and 3 are carried out in close cooperation:
Subproject 2 (IPK): Development of the joining process for functionally integrated modules made of green steel in outsourced production - KoZiMo Joining
Subproject 3 (LWF): Method development for structural joining and disassembly of painted modules in final production - KoZiMo Disassembly
