between 7Hz and 200Hz and back to 7Hz traversed in 15 minutes. This
cycle shall be repeated 12 times for a total of 3 hours for each of three
mutually perpendicular mounting positions of the cell. One of the
directions of vibration must be perpendicular to the terminal face. The
logarithmic frequency sweep is increased from 7 Hz a peak acceleration
of 1 gn is maintained until 18 Hz is reached. The amplitude is then
maintained at 0.8 mm（1.6 mm total excursion） and the frequency
increased until a peak acceleration of 8 gn occurs. A peak acceleration of
8 gn is then maintained until the frequency is increased to 200 Hz.
Criteria: No fire, no explosion, no leakage, with less than 10% of OCV drop.
Vibration test is according to the UN38.3 standard.
9.0. Safety
9.1 Overcharge test
Test method: Fully standard discharged cell is charged with 3100mA to 6.3V or until
charging time up to 1h.
Criteria: No fire, no explosion.
Overcharge test is according to the GBT31485-2015 standard.
9.2 External Short-circuit test
Test method: Fully standard charged cell is to be short-circuited by connecting the
positive and negative terminals of the cell with a circuit load having a
resistance load less than 5mΩ. Until the test time is lasting to 10min.
Criteria: No fire, no explosion.
External short-circuit test is according to the GBT 31485-2015 standard.
9.3 Forced Discharge test
Test method: A fully standard discharged cell is subjected to forced discharge at 3100mA
(1C) for 90 min.
Criteria: No fire, no explosion.
Forced discharge test is according to the GBT31485-2015 standard.
9.4 Heating test
Test method: To heat up the standard charged cell at heating rate 5° C ±2° C per minute
up to 130° C ±2° C and keep the cell in oven for 30 minutes.
