Battery Charge Depletion Prediction on an Electric Aircraft

To this end, a series of flight tests have been conducted using an unmanned electric vehicle during which the motor system batteries were monitored by a prognostic algorithm. The research presented here endeavors to produce and validate a technology for predicting the remaining time until end-ofdischarge of the batteries on an electric aircraft as a function of an expected future flight and online estimates of the charge contained in the batteries.

Flight data and flight experiment results are presented along with an assessment of model and algorithm performance
