Purpose/Principle:

The test sample battery should be placed on a flat surface, with a cross shaped rod with a diameter of 15.8 ± 0.2mm (5/8 inch) placed at the center of the sample. A 9.1kg or 10kg weight falls from a certain height (610mm or 1000mm) onto the sample. When cylindrical or square batteries undergo impact testing, their longitudinal axis should be parallel to the plane and perpendicular to the longitudinal axis of the steel column. The longest axis of the square battery is perpendicular to the steel column, and the largest surface is perpendicular to the impact direction. Each battery only undergoes one impact test.
