Elaboration and Evaluation of Concepts for Battery Modules in Electrified Aircraft Propulsion Systems

Kurzfassung

The weight of battery modules keeps hindering them from being commercially attractive as sole power supply for short-range electric passenger flight. Furthermore, the challenging requirements for aerospace applications limit the range of options for module elements and complicate the implementation of lightweight solutions. Hence, the objective of this study is to elaborate and evaluate concepts for battery modules to identify promising solutions for electrified aircraft propulsion systems. For that purpose, a house of quality is compiled to assess the relations between options for module elements and module requirements, as well as correlations between options. Potential concepts are elaborated by combining suitable elements. Finally, the concepts are evaluated to highlight the most preferable and compatible ones for aircraft battery modules.
