摘要： An assembly for an aircraft includes an aircraft electrical distribution bus, a battery, and a battery monitoring system. The battery includes a plurality of battery strings. The plurality of battery strings is configured as a main subset and a reserve subset. The battery monitoring system further includes a processor in communication with a non-transitory memory 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.

摘要： An assembly for an aircraft includes a battery, a charger, and a battery monitoring system. The battery includes a plurality of battery strings. The charger is configured to charge the plurality of battery strings. The battery monitoring system further includes a processor in communication with a non-transitory memory storing instructions, which instructions when executed by the processor, cause the processor to determine the battery string voltage for each battery string of the plurality of battery strings and identify a battery string voltage hierarchy for the plurality of battery strings, the battery string voltage hierarchy identifying at least a lowest-voltage battery string of the plurality of battery strings, at least one intermediate-voltage battery string of the plurality of battery strings, and a highest-voltage battery string of the plurality of battery strings, and sequentially charge the plurality of battery strings with the charger based on the battery string voltage hierarchy.

摘要： An assembly for an aircraft includes an aircraft electrical distribution bus, a battery, and a battery monitoring system. The battery includes a plurality of battery strings and a main battery contactor. The plurality of battery strings are electrically connected in parallel. Each battery string includes a string contactor. The string contactor is positionable in a closed string position or an open string position. The main battery contactor is electrically connected in series with the string contactor of each battery string. The main battery contactor is positionable in a closed battery position or an open battery position. The battery monitoring system is configured to control a position of the string contactor of each battery string. Control of a position of the main battery contactor in the closed battery position and the open battery position is independent of the battery monitoring system.

摘要： An assembly for an aircraft includes an aircraft electrical distribution bus, a battery, and a control system. The battery includes a plurality of battery strings. Each battery string includes a string contactor. The control system is in signal communication with the string contactor of each battery string. The control system is configured to control a position of the string contactor of each battery string in a closed string position or an open string position. The control system is configured to: detect a fault in a faulted first battery string of the plurality of battery strings and position the string contactor of the faulted first battery string in the open string position, in response to the detected fault in the faulted first battery string and maintain the string contactor of at least one unfaulted second battery string of the plurality of battery strings in the closed string position.
