DETECTION OF A MALFUNCTION IN AN ELECTROCHEMICAL ACCUMULATOR

摘要

The invention relates to an electrochemical accumulator (3), comprising: -a casing (301); -at least two electrodes (31, 33) and an electrolyte contained in the casing; -at least ferromagnetic material contained inside the casing, said ferromagnetic material having remanent magnetism; -a magnetic sensor arranged outside the casing and capable of measuring the variations in magnetic fields inside the casing; -a circuit configured to determine the temperature inside the casing on the basis of the magnetic field measured.
