Abstract

A propulsion system (20) for an aircraft includes a battery, an electrical distribution system (66), and a ground-based charger (86). The battery (64) includes a plurality of battery strings (72). Each of the plurality of battery strings (72) includes a plurality of battery cells (76). The electrical distribution system (66) includes a battery string switch assembly (98). The battery string switch assembly (98) is operable to electrically interconnect each of the plurality of battery strings (72) together in parallel. The ground-based charger (86) is electrically connected to the electrical distribution system (66). The ground-based charger (86) includes a charger controller (132). The charger controller (132) is configured to determine a battery charging profile (138) specific to the battery (64) and charge the battery (64) by supplying electrical power to the electrical distribution system (66) at a set voltage and a set current defined by the battery charging profile (138).
