Safety Performance:

NO.	Test iterm	performance criteria	Test conditions and methods
1	Vibration	No fire, no explosion, no liquid leakage	Ref.: UL1642-16 After standard charging, the battery shall withstand vibration with amplitude of 0.8mm, and the vibration frequency varies at the rate of lHz / min in the range of 10-55 HZ, and the vibration is 60min.
2	Heating	No fire, no explosion	Reference: GB 38031 8.1.5 After standard charging, the oven temperature was increased to 130℃ ± 2℃ at 5 ± 2℃ / min, retaining this temperature for 30min and observing for 1 hour.
3	Short circuit	No fire, no explosion	Reference: GB 38031 8.1.4 After standard charging, observe the battery positive terminal and negative terminal through the external short circuit l 0min (external line resistance <5m Ω) at 25℃± 3℃ for 1 hour
4	Overcharge	No fire, no explosion	Reference: GB 38031 8.1.3 After standard charging, the battery was stopped at 25℃± 3℃ with 1C constant current to 5.0V or 120% SOC and observed for 1 hour.
5	Over-put	No fire, no explosion	Reference: GB 38031 8.1.2 After standard charging, the battery was discharged at 1C and current at 25℃± 3℃ until the discharge time reached 90min and observed for 1 hour.
6	Heavy shock	No fire, no explosion	Ref.: UL 1642-14 After standard charging, a round rod of 15.8mm diameter was placed in the center of the battery, and a 9.1 Kg heavy hammer was dropped vertically from the height of 610mm at the center of the battery
7	fall-down	No fire, no explosion	Reference: GB / T 31485 6.2.5 After standard charging, the positive and negative electrode terminal of the battery sample was freely dropped down from the height of 1.0m to the cement floor and observed for 1 hour
8	squeezing	No fire, no explosion	Reference: GB 38031 8.1.7 After standard charging, the battery is placed between the two extrusion surfaces of the extrusion equipment, the cylindrical battery core shaft is parallel to the extrusion plane, with the extrusion speed of 2mm / s, gradually increase the pressure to the deformation reaches 15% or the extrusion pressure reaches l 00kN or 1000 times the battery weight, maintain the pressure of l 0min, and observe for 1 hour.
9	Depression	No fire, no explosion	Ref.: UL1642-19 After standard charging, the battery is stored for 6 hours at an absolute pressure of 11.6Kpa and a temperature of 20 soil of 5°C.
