Over Discharging Test
After fully charging the 3.2V 135Ah battery module, discharge it at 1I1 for 90 minutes and observe for 1 hour. There should be no explosion, fire, or leakage.
Test results: no explosion, fire, or leakage.
Over Charging Test
After fully charging the 3.2v 135ah battery module, discharge it at a current of 1I1(A) to any cell battery until it reaches 1.5 times of charging termination voltage specified in the enterprise technology condition or the discharging time reaches 1 hour. There should be no explosion or fire.
Test results: no explosion, fire.
Short Circuit Test
Fully charge the battery module and have an outer short circuit for 10 minutes. The outer circuit resistance should be less than 5mΩ. Observe it for 1 hour, and there should be no explosion or fire.
Test results: no explosion, fire.
Drop Test
Fully charge the battery module with the positive and negative electrodes facing down. Drop it from a height of 1.2 meters to the concrete floor and observe it for 1 hour. There should be no explosion, fire, or leakage.
Test results: no explosion, fire, or leakage.
High Temperature Test
Fully charge the battery module and put it in the environment simulation box. Raise the temperature from room temperature at a rate of 5℃/min to 130℃±2℃. Keep it for 30 minutes and stop heating and observe it for 1 hour. There should be no explosion or fire.
Test results: no explosion, fire.
Crush Test
Fully charge the battery module and apply pressure perpendicular to the arrangement direction of the cell batteries at a rate of (5±1)mm/s until the deformation amount reaches 30%, or the pressing force reaches as great as 1000 times the module weight or the greater number listed in the graph 1. Observe it for 1 hour and there should be no explosion or fire.
Test results: no explosion, fire.
