2. Safety Performance

 
 

ItemsTest Method and ConditionCriteria

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,
Noexplosion, No fire,
No smoking, No leakage.

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.
Cut circuit of resistance; test the battery’s voltage after charging with 1C constant current for 5 seconds.

The appearance is normal,
Noexplosion, No fire,
No smoking, No leakage.
