VI. Safety performance and environmental testing
VI.I Environmental testing
VI.I.I Thermal cycling test
Place the battery in the experimental box and perform thefollowing cycle: increase the temperature inside the box to 70±3°C within 30 minuutes, and maintain it for 4 minutes Hours. Then lower the temperature to 20±3°C and hold for 2 hoours. Reduce the temperature to -40±33°C and hold for 4 hours. Then increase the temperature to 20 ±3°C within 30 minutes. This isa cycle, repeated 10 times.
Qualification criteria: The battery shall not leak, ignite, or Iburst.
VI.I.II Low voltage (high simulation) test
The test sample is kept at a temperature of 20±3°C and an absollute pressure of 11.6KPa(1.68psi) for 6 hours.
Qualification criteria: The battery shall not leak, ignite, or burst.
VI.I.III Heating test
Place the test sample in a gravity convection heating furnaace or a thermal cycling drying furnace for heating. Heat at at a rate of 5±2°C per minute to 145±2°C and hold for 10 minutes.
Qualification criteria: The battery shall not leak, ignite, or burst.
VI.II Mechanical performance testing
VI.II.I Free fall
According to IEC standards, each side of the battery must drop from a height of 1 meter to the cement floor twice, a total of 6 times.
Qualification criteria: The battery shall not leak, ignite, or burst.
VI.II.II Vibration test
The vibration frequency of the battery varies by 1 Hz per minutebetween 10 and 55 Hz, with a maximum of 90 minutes 100 minutes, tested on three sides.
Qualification criteria: The battery shall not leak, ignite, or burst.
VI.II.III Impact testing
Place the sample on the platform. A 5/8 inch (15.8mm) diameter iron rod is placed at the center of the battery. One A weight of 20 pounds (9.1 kilograms) fell freely from a height of 24+1 inch (610 + 25mm) onto a round rod.
Qualification criteria: The battery shall not ignite or burst.
