Item
Test Method
Standard
1
Overcharge
After normal charge, test the batteries’ initial state and capacity.
Charge to 10.0V at 3C, then charge at CV mode to 0.01C.
Observe battery’s variation of appearance.
No explosion,
No fire.
2
Over
Discharge
After normal charge, test the batteries’ initial state. When the
batteries are normal, Discharge to 0V at 0.5C. Observe
battery’s variation of appearance.
No explosion,
No fire.
3
External
Short-circuit
After normal charge, test the batteries initial state, Keep the
battery into explosion protection cover, short-circuit the
positive and negative terminals directly (general resistance
shall be less than or equal to 50mΩ). Stop the test when the
temperature falls to 10℃ lower than the peak value. Observe
the variation of the batteries’ appearance and temperature.
No explosion,
No fire.
4
Thermal
Abuse
Test the batteries’ initial state and capacity. Standard charge.
Put battery into oven, increase the temperature to 130±2℃ at
rate of （ 5±2℃ ） /min, and keep it for 30min. Observe the
variation of batteries’ appearance.
No explosion,
No fire.
5
Drop
After normal charge, test the batteries’ initial state and capacity.
Then let it fall from a height of 1m (the lowest height) to a
smooth cement floor, twice.
No explosion,
No fire.
6
Heavy Impact
A diameter of 15.8 mm steel rod is placed in the middle of the
fully charged battery, then the weight of 10Kg hammer from
1.0m height free falls to the battery upper.
No explosion,
No fire.
7
Extrusion Test
Place the battery in between the pressing surface of extrusion
apparatus, parallel the axes of cylindrical battery to the pressing
surface, and gradually increase pressure up to 13KN, keeping
the pressure for 1min.
No explosion,
No fire.
