Abstract: A battery management system and method for performing a battery state and, optionally, health parameter observation is disclosed, 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 some embodiments, a battery health observation is further performed independently by the two lanes, wherein the first lane employs an aging 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.

Abstract: A method, system and computer-readable storage medium for data backup by a backup server having local storage. In normal mode of operation the backup server stores any ingest data in the local storage. A redirect monitor continuously monitors the capacity utilization of the local storage. When the capacity utilization surpasses a preset threshold, the backup server is switched to operate in redirect mode, where newly received ingest data is redirected to alternate storage. The alternate storage may be, e.g., cloud storage or storage as a service facility. Thereafter the redirect monitor checks the utilization of the local storage and if that drops below a preset safety margin, the backup server reverts to normal operating mode. The backup server may or may not copy all redirected data from the alternate storage to the local storage, depending on the setup.
