BATTERY MANAGEMENT SYSTEM, TEMPERATURE SENSING SYSTEMS AND METHODS

A propulsion system for an aircraft (1000) includes a battery (64), a battery management system (68), and an engine controller (28). The battery management system (68) includes a plurality of first battery temperature sensors (110), at least one second battery temperature sensor (110), and a single-channel battery management system (BMS) controller (92). The single-channel BMS controller (92) includes a BMS control channel connected in signal communication with the plurality of first temperature sensors (110). The engine controller (28) includes a first engine control channel (98) and a second engine control channel (100). The first engine control channel (98) is connected in signal communication with the BMS control channel to form a first control lane (142A). The second engine control channel (100) is connected in signal communication with the at least one second battery temperature sensor (110) to form a second control lane (142B).
