Impact Test
After standard charged,the cell is to be
placed on a flat surface.A 5/8 inch(15.8mm)
diameter bar is to be placed across the center
of the sample.A 20 pound(9.1kg) weight is to
be dropped from a height of 24±1 inch(610
±25mm) onto the sample.
NO fire, No explode
7.5
Crush Test
After standard charged,the cell is to be
crushed between two flat surfaces.The force
for the crushing is to be applied by a
hydraulic ram with a 1.25inch(32mm) diameter
piston.The crushing is to be continuing until
a pressure reading of 2500 psig(17.2Mpa)
isreached on the hydraulic ram,applied force
of 3000 pounds(13KN).Once the maximum
pressure has been obtained it is to be
released.
NO fire, No explode
7.6
Vibration
Battery charged by the regulation, after the
battery is fixed on the vibration table,
don't make the battery out of shape, with
sinusoidal vibration, and within 15 min in
logarithmic sweep from 7 hz frequency sweep
to 200 hz and return to the 7 hz. Vibration
along three mutually perpendicular
direction of sample (one direction is
perpendicular to the plane of the cathode)
must match the sample, according to the
logarithmic sweep in each direction way to
12 repetitions, vibration 3h. Logarithmic
frequency sweeping method is as follows: 7
hz ~ 18 hz maintain peak acceleration of 9.8
No leakage, no fire and no
explosion.
