6.6 ESD Test/静电放电试验
For each output terminal of the battery, the contact discharge test ±4KV (5 times each) and the air
discharge test ±8KV (5 times each) are carried out. The interval between the two discharge tests is one
minute. The batteriess should not catch fire or explode, and the protective circuit should not fail.

6.7 Vibration Test/振动试验
Standard charged batteries use sinusoidal wave vibration, and sweep frequency from 7Hz to 200Hz in
15 minutes by logarithmic sweep mode, and return to 7Hz. Vibration is carried out in three directions
perpendicular to each other, and repeats 12 times in each direction according to the sweeping mode
mentioned above. Vibration lasts for 3 hours. The logarithmic sweep mode is as follows: maintain peak
acceleration of 9.8m/s2 from 7Hz to 18Hz. Keep the amplitude at 0.8mm ( displacement 1.6mm ) until the
peak acceleration reaches 78.4m/s2 ( frequency about 50Hz ). Maintain a peak acceleration of 78.4m/s2
until the frequency increases to 200Hz. After the test, a charge and discharge cycle is carried out according
to the 5.1 and 5.2. The batteries should not catch fire, explode or leak.
Drop the fully charged battery from a high 1.5m away from the cement floor onto each side of the
battery for 6 times. After the test, a charge and discharge cycle is carried out according to the 5.1 and 5.2.
The batteries should not catch fire, explode or leak.
