Abstract

An assembly (24) for an aircraft (1000) includes an aircraft electrical distribution bus (66), a battery (70), and a battery monitoring system (72). The battery includes a plurality of battery strings (80). The plurality of battery strings is configured as a main subset (106) and a reserve subset (108). The battery monitoring system further includes a processor (100) in communication with a non-transitory memory (102) storing instructions, which instructions when executed by the processor, cause the processor to electrically connect the reserve subset to the aircraft electrical distribution bus by: determining the bus voltage and the battery string voltage of each battery string of the reserve subset, identifying a threshold voltage range of the reserve subset for electrically connecting the reserve subset to the aircraft electrical distribution bus, where identifying the threshold voltage range is based at least on the bus voltage, and electrically connecting at least one battery string of the reserve subset to the aircraft electrical distribution bus with the bus voltage within the identified threshold voltage range.
