Safe and quiet flying through a high degree of automation and electric drives using the example of e-Schlepps

Larger batteries made of lithium-ion cells are gradually finding their way into aviation. However, they have to be designed, developed and manufactured elaborately and specifically for individual applications. In particular, the different requirements in terms of safety, power and energy demand, and geometry call for individualized products. A modular battery concept is best suited for this purpose.

In this project, a modular battery concept will be developed and built that can map the different requirements of different aircraft types. The modular concept will significantly reduce the cost and time of battery integration. In addition, these flexible battery modules can be quickly and easily replaced during operation. In collaboration with Garrecht Avionik GmbH, the Institute of Flight Mechanics and Flight Control (University of Stuttgart) and the Institute of Aircraft Design (University of Stuttgart), the modular battery concept and the appropriate charging technology will be designed, built and integrated into the e-Genius research aircraft. This will test the practical suitability of the battery modules.

Our goal in the project is to bring a modular battery concept into our portfolio that will enable more aircraft manufacturers to enter this clean technology due to lower costs and shorter development times.
