Safety Characteristics Test

S/N	Items	Criteria	Test Instructions
1	Overcharge	No fire, no explore,cell temperature no above 150°C.	After fully charged at constant current of 0.5C2.5A, batteries are charged continually to 14.4V or for 1.5h at constant current of 1A, then 14.4V CV for 7h.
2	Over discharge	No fire, no explore,cell temperature no above 150°C.	Discharge to limited voltage with 0.5C(2.5A) at 20±2 °C. Then discharge to 0V with 0.2C(1A).
3	Short-circuit test	No fire, no explore,cell temperature no above 150°C.	Batteries are short-circuited by connecting the positive and negative terminals with a resistance load of ≤50mΩ until batteries’ temperature come back to no above RT 10°C.
4	Heating test	No fire, no explore,cell temperature no above 200°C.	Batteries are heated in a circulating air oven at a rate of 5°C±2°C per minute to 85°C, and then placed for 120 minutes at 85°C.

To insure safety, PCB &BMS Parameter should meet requirement as below.
