BATTERY CHARGING CONTROL SYSTEMS FOR AIRCRAFT BATTERIES

A propulsion system (20) for an aircraft (1000) includes a battery, an electrical distribution system (66), a ground-based charger (86), and an engine controller (28). The battery includes a plurality of battery strings each including a plurality of battery cells (72). The electrical distribution system includes a battery string switch assembly (98) operable to electrically interconnect each of the plurality of battery strings together in parallel. The ground-based charger is electrically connected to the electrical distribution system. The ground-based charger includes a charger controller (132) including a simple electronic hardware (SEH) system. The engine controller is connected in signal communication with the SEH system. The engine controller is configured to determine a battery charging profile (138) specific to the battery and charge the battery by controlling the ground-based charger, through the SEH system, to supply electrical power to the electrical distribution system at a set voltage and a set current defined by the battery charging profile.
