Abstract
A method for detecting a malfunction of an acoustic sensor coupled to an electrochemical generator includes applying an electrical signal at a given frequency and a given amplitude, termed the signal frequency and signal amplitude; measuring, by the acoustic sensor, an acoustic signal emitted by the electrochemical generator in response to the application of the electrical signal; and, when the amplitude of the acoustic signal is below a predetermined threshold value, and detecting a malfunction of the acoustic sensor.
