Safety Test with UN38.3 Standard for  Lithium Polymer Battery For Table PC 1.6ah 3,7V 0850110 Charge And Discharge 0.5C

1 / Short Circuit Test (20±2℃ ) process and result

  1. sort  fresh battery samples 100% fully charged each test sample battery, in turn,
  2. the battery should be is short-circuited by connecting the (+) and (-) terminals of the battery with a Cu wire having a maximum resistance load of 0.1Ω.
  3. At room temperature(20±2℃ ).
  4. Test result: No explosion, No fire The Temperature of the surface of the Cells are lower than 150℃

2 / Vibration Test  process and result

  1. Standard charging the samples
  2. Fixed the cell to vibration table and subjected to vibration cycling that the frequency is to be varied at the rate of 1Hz per minute between 10Hz an 55Hz,
  3. the excursion of the vibration is 1.6mm.
  4. The cell shall be vibrated for 30 minutes per axis of XYZ axes.
  5. Test result: No explosion,No fire

3 / Crush Test  process and result

  1. sort fresh battery samples 100% fully charged
  2. Crush between two flat plates. Applied force is about 13kN(1.72Mpa) for 30min.
  3. Test result: No explosion,No fire

 

4 / Drop Test process and result

  1. The samples should  be dropped from a height of 1 meter twice onto concrete ground.
  2. Test result: No explosion,No fire

 

 

5 / Short Circuit(60±2℃ ) test process and result

      sort fresh battery samples 100% fully charged each test sample battery, in turn,

  1. the battery should be is short-circuited by connecting the (+) and (-) terminals of the battery with a Cu wire having a maximum resistance load of 0.1Ω.
  2. At room temperature(60±2℃ ).
  3. Test result: No explosion, No fire The Temperature of the surface of the Cells are lower than 150℃

 

6 / Impact test process and result

  1. A 56mm diameter bar is inlayed into the bottom of a 10kg weight.
  2. And the weight is to be dropped from a height of 1m onto a sample battery 
  3. then the bar will be across the center of the sample.
  4. Test result:No explosion, No fire

 

7 / Forced Discharge test process and result

  1. sort fresh battery samples 100% fully charged
  2. Discharge the samples at a current of 1 C5A for 2.5h.
  3. Test result:No explosion, No fire

 

8 / Nail Pricking test process and result

  1.          sort fresh battery samples 100% fully charged
  2. Prick through the sample battery with a nail having a diameter of 3mm and remain 2h.
  3. Test result : No explosion, No fire
