Disassembly of electric vehicle batteries using the example of the Audi Q5 hybrid system

Abstract

The rising number of electric vehicles comes along with an increasing demand for Li-Ion batteries. As resources such as lithium are valuable it is economically worthwhile to recycle EV batteries. One of the first steps of every battery recycling process is the disassembly, which can be a quite time and cost consuming process and hence has to be planned properly. Using the battery of the hybrid car Audi Q5 as a case study, a planning approach for the disassembly will be discussed in this paper. Therefore, disassembly sequences will be derived from a priority matrix and a disassembly graph will be drawn up. Finally, recommendations for the design of the disassembly system and work stations will be given.
