safety performance testing
A round bar weighting around 9kgs with a diameter of 15.8 mm is placed on the battery falling on the battery surface from 61±2.5cm of height. An evaluation is done to assess situations that may cause internal short circuits, such as possible impacts or crushing during shipping
Using a press machine with a steel needle of 3-3.5mm diameter, the battery is punched at 10-40mm/s speed and there should be no smoke, no fire, no explosion after pulling it out. The internal short circuit condition is evaluated and simulated by this prodding test .
