5. Conclusions Using the example of the Audi Q5 Hybrid battery system, a planning approach for the disassembly of electric vehicle batteries has been demonstrated. Based on a priority matrix, a disassembly sequence for the Q5 battery system has been derived.
The design solutions are assessed from an assembly, disassembly and modularity point of view to establish what solutions are of interest. Based on the evaluation, an “ideal” battery is developed with focus on the hardware, hence the housing, attachment of modules and wires, thermal system and battery management box.
If the modules would move around, the energy supply to the vehicle is disabled and the modules could potentially collide and get damaged. Moreover, by using the “click on, click off” solution for high voltage batteries might contribute to faster wear out on the connections and a decreased isolation.
This has 8 modules and a capacity of 101 kWh (0.01 kWh/cell) meanwhile the biggest battery in this product family has a capacity of 203 kWh and total of 16 modules. (56) One module consists of 12 so called Supercells, a Supercell is small module holding 84 cells in a housing connected to each other in parallel.
Another good example of module assembly and disassembly is found in Tesla S which also has modules mounted to the pack with four screws. To access these screws a plastic cover must be removed, but once that is gone, it is easy to unscrew the modules and later on lift them.
