The vibration test method of Nickel–metal hydride battery is:


After discharging the battery at 0.2C to 1.0V, charge it at 0.1C for 16 hours, and let it stand for 24 hours before vibrating according to the following conditions:


Amplitude: 0.8mm


Shake the battery between 10HZ-55HZ, increasing or decreasing at a vibration rate of 1HZ per minute.


The voltage change of the battery should be within ± 0.02V, and the internal resistance change should be within ± 5m Ω. (Vibration time is within 90 minutes)


The vibration experimental method for lithium batteries is:


After discharging the battery at 0.2C to 3.0V, charge it at 1C constant current and voltage to 4.2V, with a cut-off current of 10mA. After 24 hours of storage, follow the following steps


Conditional vibration:


Conduct vibration experiments with a vibration frequency ranging from 10 Hz to 60 Hz and then to 10 Hz within 5 minutes, with an amplitude of 0.06 inches. electric


The pool vibrates in the three axis direction, with each axis vibrating for half an hour.


The voltage change of the battery should be within ± 0.02V, and the internal resistance change should be within ± 5m Ω. Vb
