Test vibration performance of three different directions
(flat, on its side, erected)
(1) Side Lay
(a) At peak acceleration is 5G to take 2000 times sinusoidal cycles in the frequency range 10~30Hz.
(b) Raise frequency from 10Hz to 90Hz, then return to 10Hz. Take sine sweep vibration for 60 times with scan rate of1Hz/s. The entire cycle is 6h. Adopt following acceleration levels:
Frequency range(Hz) Peak acceleration(G)
10~20 3.0
20~40 2.0
40~90 1.5
90~140 1.0
140~190 0.75

(2) Keep upright
(a) At peak acceleration is 3.5G to take 4000 times sinusoidal cycles in the frequency range 10~30Hz.
(b) Raise frequency from 10Hz to 190Hz, then return to 10Hz, take sine sweep vibration for 60 times with scan rate of1Hz/s. The entire cycle is 6h. Adopt following acceleration levels:
Frequency range(Hz) Peak acceleration(G)
10~15 2.5
15~30 1.75
30~60 1.25
60~110 1.0
110~190 0.75

(3) Flatwise
Test according to (1) methods.
Test DC resistance, insulation, sealing performance of battery module before and after vibration. Test the data acquisition and transmission is abnormal or not after vibration if there is protection board.
