No	Project	Standard	Testing method
1	Over-charge performance	No exploding, No fire The highest temperature <130°C	After standard charge ,charge with 3C5A to 72V, then change to charge with constant voltage and stop charge until the current is 0.05C5A, check the temperature and appearance of the battery.
2	Over-discharge performance	No exploding, No fire	After standard charge,discharge with 0.2C5A to 32V,then connect the positive and negative with 10Ω resistor,rest for 60 minutes.check the temperature and appearance of the battery.
3	Short-circuit performance in normal temperature	No exploding, No fire The highest temperature <130°C	After standard charged,keep in bell glass and connect positive and negative to short-circuit(the total impedance is not over than 50mΩ),stop testing when the temperature of the battery reduce 10 °C .check the temperature and appearance of the battery.
4	Nail performance	No exploding, No fire The highest temperature <130°C	After standard charge,lay on the nog,connect with thermocouple,then at a height to impale the middle of battery rapidly with a diameter of 3mm nail.,check the temperature and appearance of the battery.
5	Heating impact safety performance	No exploding, No fire	After standard charge,lay in a hot case,connect with thermocouple,with speed of(5 °C±2 °C)/min to up to 150 °C±2 °C then keep for 30 minutes.check the temperature and appearance of the battery.
