2. Safety Performance
| Items | Test Method and Condition | Criteria |
|
Over-Charge Protection |
At 20±5℃ conditions,after full-charging the battery with 0.5C and set the constant current and voltage supplier with 2times of the nominal voltage and current, then load it to the battery for 8h. |
The battery should be no leakage,deformation,smoking and explosion during the test processes. |
|
Over-Discharge Protection |
At 20±5℃ conditions, discharge battery to 6.0V with 0.5C constant current, then discharge with 30Ω loading for 24 hours. Check the appearance of battery. |
The appearance is normal, |
|
Short-Circuit Protection |
After fast-charging, use a cable of 0.1Ω resistance to short the battery for 1 hour. Then check the appearance of battery. |
The appearance is normal, |
Note: Size and capacity can be customized according to your requirements.
