Publication number: 20230155196Abstract: A method for the diagnosis of thermal runaway in an electric battery having at least one stack of electrochemical cells connected to one another in series. The diagnosis method provides for the steps of: measuring a first electric voltage at the ends of each electrochemical cell; measuring a second electric voltage at the ends of the entire stack of electrochemical cells; calculating a difference between the second electric voltage and the sum of all first electric voltages; and diagnosing a thermal runaway of an electrochemical cell, if the first electric voltage of the electrochemical cell is smaller than a first threshold value and if, simultaneously, the difference between the second electric voltage and the sum of all first electric voltages is smaller than a second threshold value.Type: ApplicationFiled: November 1, 2022Publication date: May 18, 2023Inventors: Roberto BETRO', Andrea Benoit ABBIATI, Irene DONA', Ugo SITTA, Matias TRONCOSO, Elena LIGABUE, Luca POGGIO
