Abstract

Embodiments are provided for charging system for an aircraft. The charging system may comprise a plurality of electric propeller units (EPUs), a plurality of battery packs configured to power the plurality of EPUs, a charge control unit configured to determine a target charge level for each of the plurality of battery packs, receive charge status information from each of the plurality of battery packs, and upon determining that a target charge level of at least one of the battery packs has been reached, command the at least one battery pack to disconnect from a common charging bus having a high voltage connection to a power source external to the aircraft.
