DEVICES FOR PROVIDING CONSTANT PRESSURE ON BATTERY CELLS UNDER TEST AND ASSOCIATED SYSTEMS AND METHODS

A battery cell testing system is provided. This system includes a platform and a force distributor disposed above the platform. The force distributor has a plate and a plurality of force distributor sheets disposed above the plate. The system also includes an arm disposed above the force distributor and a rod passing through and perpendicular to the arm, with the rod being in contact with the force distributor. In this system, a gravitational force of a weight is applied on one end of the arm such that the gravitational force of the weight results in a constant pressure on the plate, via the rod and the plurality of force distributor sheets. Additionally, the applied pressure on the plate is proportional to the gravitational force and a position on the arm through which the rod passes through.
