Abstract

An assembly for an aircraft propulsion system (20) includes a battery (64), an electrical distribution system (66), a battery cell voltage sensor (132A), and a controller (28, 108). The battery (64) includes a plurality of battery cells (76). The electrical distribution system (66) is operable to electrically interconnect the battery (64) with a charging power source (62, 86). The battery cell voltage sensor (132A) is operable to measure a cell voltage of a first battery cell of the plurality of battery cells (76). The controller (28, 108) is connected in signal communication with the battery cell voltage sensor (132A) and the HVPDU (88). The controller (28, 108) configured to execute a charging sequence for the battery (64), determine a change in cell voltage of the first battery cell (76), determine a test cell resistance of the first battery cell (76), determine a change in resistance of the first battery cell (76), and identify a presence or an absence of an end-of-life condition of the first battery cell (76).
