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.
