Abstract

A propulsion system (20) for an aircraft (1000) includes a battery (64) and a battery sensor assembly (92). The battery (64) includes a plurality of battery strings (74). A first battery string of the plurality of battery strings (74) includes a plurality of substring assemblies (94). Each of the substring assemblies (94) includes a battery substring (96), a first substring contactor (98), and a first substring controller (102). The battery substring (96) includes a plurality of battery cells (106) electrically connected together. The first substring contactor (98) is electrically connected with the battery substring (96). The first substring contactor (98) is positionable in a closed state or an open state. The first substring controller (102) is configured to control a position of the first substring contactor (98) in the closed state or the open state. The battery sensor assembly (92) includes a cell temperature sensor (92A) for each of the plurality of battery cells (106). The cell temperature sensor (92A) is connected in signal communication with the first substring controller (102).
