As the number of electric vehicles increases, vehicle manufacturers will soon need to keep battery modules (cell assemblies) and battery packs in stock in order to be able to supply spare parts promptly. This is where the proposed funding project comes in: These battery packs must also be constantly charged and discharged to a certain extent during storage in order to maintain capacity. If several hundred or thousand batteries are stored,  a correspondingly large energy store is created. However, this energy storage cannot yet be used, as existing BMS can only be used in the vehicle and do not support the partial operation of incomplete batteries.

Of key importance in this context is the use of this universal battery management system to be developed at the level of car dealerships and repair workshops. The innovative new battery management system puts these SMEs (small and medium-sized enterprises) in a position to address the issue of repairability with a view to optimizing resources. This innovation gives these companies the opportunity to store, charge and discharge "incomplete" battery packs, which can result from the removal of individual modules (up to residual quantity 1), in a professional and appropriate manner.

This enables SMEs to carry out maintenance and repair work on the battery systems at short notice and makes a significant contribution to using existing resources appropriately and conserving basic raw materials by acting responsibly and sensitively.

The aim is to develop a universal battery management system at the level of car dealerships and repair workshops.
