    Safety Performance  for Single Cell

     

    Tac single cell passed the UN38.3 Certification to keep the safe perofrmance of battery pack.

     

    No. Items Test Method and Condition Criteria
    1 Overcharge (3C/10V) Charge the cell with current of 3C, till the voltage of the cell reach 10V and current reduce to 0A. Monitor the variation of the cell’s temperature in the process of the test. Stop the test when the temperature of the cell falls to value 10ºC lower than the peak value.

    No explosion

    No fire

    2

    Over

    Discharge

    Charge: 1C CC to 3.65V and CV to 0.05C cut off, Discharge the cell with 1C current for 2.5 hours.

    No explosion

    No fire No leakage

    3 Nail test Charge: 1C CC to 3.65V, and CV to 0.05C cut off, Standby for 1 hour, then measure OCV, A nail is penetrated vertically through the center of the cell and left for over 1h. The diameter of the nail is 2.5~3.5 mm.
