Estimation of Critical Performance Parameters of the Thermocouple in a Bypass Device, Made of SME Alloy, Designed for LIABs on Spacecraft

Abstract:

Critical parameters of the bypass device thermocouple made of SME alloy are optimized on the base of the developed thermal model of Lithium-Ion storage battery (LISB) for space applications. It is shown that the terminal is the most dangerous element within LIAB. To ensure LIAB reliability in case of one cell failure, a temperature limit in the vicinity of the terminal is set to 100°C, and the bypass device action time – to 2–3 s, which corresponds to phase transitions temperature range of the thermocouple spring made of SME alloy.
