  "textContent": "The method involves measuring an acoustic emission response of a battery for internal states of the battery (E1), and recording response characteristic signals. The response characteristic signals are processed (E2), and an acoustic signature of the internal state is determined by calibrating a relationship between common parameters of the signals and an internal state of the battery. An acoustic emission response of another battery is determined to obtain a characteristic signal, and an internal state of the latter battery is estimated from the characteristics of the acoustic signature. An independent claim is also included for a system for estimating an internal state of a battery.",
