11 Thermal Shock
No fire, No explosion
Battery is heated in a circulating air oven
at a rate of (5±2)℃ per minute to 130℃,
and then placed for 30 minutes at 130℃.
12 Overcharge No fire, No explosion
Place battery connected
thermocouple
in a ventilated cabinet, connect the
positive and negative to CC/CV source,
and adjust constant current to 3C
5
A,
and constant voltage to N*10V. Charge
the battery to N*10V and current to 0 A.
Then monitor the changes of
temperature. If the temperature of battery
drops to about 10℃ lower than the max
temperature, test is finished.
13
Short circuit
No fire, No explosion. The out
side temperature of the battery is
less than 130℃.
Place battery connected
thermocouple
in a ventilated cabinet, short-circuit the
positive and negative, then monitor the
changes of temperature. If the
temperature of battery drops to about
10℃ lower than the max temperature,
test is finished.
14 Nail No fire, No explosion
Put battery in the nail test platform.
then, use a diameter 8 mm steel tip to
poke through into hole.
Finally, use a heavy hammer to blow the
battery
15
Cycle life Cycle life ≥ 300
At 20±5℃,charge battery with 0.5 C
5
A to
4.2V and then charge it with constant
voltage to the current less than 20mA.
Stop charge and display for 0.5~1 hour.
Then discharge it with 1 C
5
A to cut-off
voltage. Display for 0.5 ~1 hour, do next
charge and discharge cycle. Repeat
these steps. Stop it until the continuous
two cycle discharge time is less than 48
minutes.
