Abstract

A propulsion system (20) includes a battery (64), a plurality of temperature sensors (110), and a controller (92). The battery includes a plurality of battery cells (112). Each temperature sensor of the plurality of temperature sensors is disposed at a respective battery cell of the plurality of battery cells. The controller includes a first control channel (94). The first control channel is configured to monitor a temperature of each battery cell of the plurality of battery cells measured, execute a model (136) trained to identify a faulted condition or an unfaulted condition of each temperature sensor of the plurality of temperature sensors using one or more operating parameters of the propulsion system, and identify the faulted condition or the unfaulted condition of a first temperature sensor of the plurality of temperature sensors using the model to determine an expected temperature range for the first temperature sensor based on the one or more operating parameters.
