PASSIVE DETECTION OF THERMAL RUNAWAY USING ACOUSTIC WAVES

A computer system (100) comprising processing circuitry (102) configured to: receive sensing data (D) from at least one sensor (104) arranged to detect sound waves emitted from electrical energy storage cells (106) of an electrical energy storage system (108), the sensing data indicating at least one characteristic of the sound waves, apply an algorithm (110) configured to predict a thermal runaway event by analyzing the sensing data, provide a message (W) if the outcome of the analysis is that a thermal runaway is predicted.
