Abstract

The present invention relates to a battery management system and method for performing a battery state and optionally health parameter observation, in particular cell state-of-charge (SOC) observation, with two redundant, independent and dissimilar lanes. Specifically, a SOC determination in a first one of the lanes is based on Coulomb Counting. The other lane employs a different algorithm than Coulomb Counting. In embodiments, a battery health observation is further performed independently by the two lanes, wherein the first lane employs an ageing model and the other lane a different (dissimilar) algorithm. On the basis of state and health observation, state (state of function) of the battery system can be predicted to determine a range of flight in accordance with a predetermined flight profile.
