Abstract

A propulsion system (20) includes a battery (64), a plurality of temperature sensors (110), and a controller (92). The battery (64) includes a plurality of battery cells (112). The plurality of temperature sensors (110) includes a plurality of first temperature sensors (110A; 110C; 110E; 110F) and at least one second temperature sensor (110B). Each temperature sensor of the plurality of first temperature sensors (110A; 110C; 110E; 110F) is disposed at a respective battery cell of the plurality of battery cells (112). The at least one second temperature sensor (110B) is disposed at the plurality of battery cells (112). The controller (92) includes a first control channel (94) and a second control channel (96). The first control channel (94) is configured to monitor a T1 temperature of each battery cell of the plurality of battery cells (112) measured using the plurality of first temperature sensors (110A; 110C; 110E; 110F). The second control channel (96) is configured to monitor at least one T2 temperature of the plurality of battery cells (112) measured using the at least one second temperature sensor (110B).
