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
- sort fresh battery samples 100% fully charged each test sample battery, in turn,
- 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.
- At room temperature(20±2℃ ).
- Test result: No explosion, No fire The Temperature of the surface of the Cells are lower than 150℃
2 / Vibration Test process and result
- Standard charging the samples
- 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,
- the excursion of the vibration is 1.6mm.
- The cell shall be vibrated for 30 minutes per axis of XYZ axes.
- Test result: No explosion,No fire
3 / Crush Test process and result
- sort fresh battery samples 100% fully charged
- Crush between two flat plates. Applied force is about 13kN(1.72Mpa) for 30min.
- Test result: No explosion,No fire
4 / Drop Test process and result
- The samples should be dropped from a height of 1 meter twice onto concrete ground.
- 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,
- 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.
- At room temperature(60±2℃ ).
- Test result: No explosion, No fire The Temperature of the surface of the Cells are lower than 150℃
6 / Impact test process and result
- A 56mm diameter bar is inlayed into the bottom of a 10kg weight.
- And the weight is to be dropped from a height of 1m onto a sample battery
- then the bar will be across the center of the sample.
- Test result:No explosion, No fire
7 / Forced Discharge test process and result
- sort fresh battery samples 100% fully charged
- Discharge the samples at a current of 1 C5A for 2.5h.
- Test result:No explosion, No fire
8 / Nail Pricking test process and result
- sort fresh battery samples 100% fully charged
- Prick through the sample battery with a nail having a diameter of 3mm and remain 2h.
- Test result : No explosion, No fire
