  • Publication number: 20250125401
    Abstract: A battery pack for an electric road vehicle includes a first electrochemical cell comprising a cathode, an anode and a solid electrolyte electrically connected thereto. The first cell has a first thickness along a direction increasing following the activation of the first cell. A first compensation element cooperates with the first cell along the direction and is subjected to a compression force, which is variable along the direction between a minimum value and a maximum value. The compensation element has a second thickness along the direction, which is variable between a maximum value and a minimum value. The first compensation element plastically deforms itself when it is subjected to a predetermined value of the compression force, which is greater than or equal the minimum value and is smaller than the maximum value, so as to plastically reduce the second thickness for values of the force exceeding the predetermined value.

  • Publication number: 20230155196
    Abstract: 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.
