Abstract
A bench for mechanical characterisation of a battery cell by applying a compression force includes a frame having a first compression plate, a movable element having a second compression plate opposite the first compression plate, a compression spring for applying a compression force to the cell between the first and second compression plates, a force sensor inserted between the movable element and the spring, and movement sensors measuring the movement between the first and second compression plates. The first compression plate includes a projecting compression zone with an area equal to a portion of interest of the cell and the frame includes a recess surrounding a thicker frame in the frame forming a pedestal supporting the first compression plate.
