SYSTEM AND METHOD FOR DETECTING THERMAL RUNAWAY USING ACOUSTIC AND GAS SENSORS

A system and method for utilizing acoustic and/or gas sensors for detecting thermal runaway in a battery system is provided. An example system may include a battery housing defining an internal battery compartment containing a battery cell. The system may further include an acoustic sensor within the internal battery compartment and positioned to receive an acoustic signal from the battery cell. Additionally, the system may include a fan attached to the battery housing and positioned to direct gasses away from the battery cell. In some embodiments, the fan may be enabled in an instance in which the acoustic sensor detects an acoustic signal indicative of thermal runaway. The system may further include an internal gas sensor and an external gas sensor, wherein an alert is transmitted in an instance in which the internal gas sensor detects a gas indicative of thermal runaway and the external gas sensor does not.
