Item
Criteria
Test Instructions
5.3.1
Overcharge
No fire or explosion
Put the batteries with thermocouple into the ventilation cabinet.
Connect the polarities to constant voltage and adjust the current to
3C5A, voltage to 4.8V. Charged the cells with 3C5A until voltage of
4.8V and current approach 0 A.
5.3.2
Short-Circuit
No fire or explosion;
The maximum
Temperature: 150℃
Put the batteries with thermocouple into the ventilation cabinet.
Batteries are short-circuited by connecting the positive and negative
terminals with a total resistance load of 100mΩ. Watch the changes of
temperature. End the test when the temperature of the batteries drops
to 10℃lower than the peak value.
5.3.3
Heating
No fire or explosion
Cell is heated in a circulating air oven at a rate of (5±2)℃per minute
to 130±2℃, and then placed for 30 minutes
5.3.4
Temperature
cycle
No leakage, no fire
or explosion
After full charge , place the battery in the temperature control box of
20±5℃, do the following steps:
⑴Put the battery into test chamber of 75℃2℃and keep for 6h.
⑵Lower the temperature to -40±2℃and keep for 6h
⑶Temperature conversion time is no longer than 30 min
⑷Repeat the above three steps for 10 cycles.
Note: Unless otherwise specified, all tests stated in this specification are conducted at the following conditions:
Temp. : 20±5℃; Relative Humidity: 25%～85%.
