Abstract
This paper discusses the importance and need for predicting battery degradation in an all-electric battery powered aircraft. This type of aircraft is expected to represent an emission-free alternative to the conventional light aircraft used for pilot training and leisure flying. The drawbacks of limited life-span of batteries, important parameters like total charge capacity and internal resistance which indicate battery health, and the need to define end-of-life (EOL) parameter values are addressed. The importance of analysing the particularities of the mission flown by light planes and the different approaches to model battery cells for battery management system (BMS) algorithms are presented. Further avenues to continue the work are also presented.
