1. Test A: High -altitude simulation >1. Purpose
Simple air transport in the low -exhaust environment. ;
2. Testing method
At the environmental temperature, the battery was placed at least 6 h under the pressure of not greater than 11.6 kPa.
The battery should have no quality loss, no leakage, non -leak Explosion, no fire.
2. Test B: Heat shock
Methods to evaluate the overallsealing performance
and internal electricity connection performance. > 2, inspection method
The battery was placed at least 6 h at a temperature of 75 C, and then at a 40 C of 1 40 C Place at least 6h under the environment. DifferentThe conversion time of temperature should not exceed 30 min. After 10 cycles of the battery inspection, at least at least
24h at the ambient temperature. The storage time of the large battery at the test temperature should be at least 12h instead of 6h.
This inspection was performed with a battery that had been checked by a high altitude simulation test.
3. Test D: impact
Simulating rough installations in transportation.
2, inspection method
The rigid branch of all fixed planes that can be checked by the ability to support the battery will be fixed on the detection equipment on the detection equipment Essence Each of each of the batteries in three
is fixed perpendicular to each other each position has been impacted 3 times in a total of 18 times. See Table 6 for each impact parameter.
This test was performed with a battery used for vibration test. > 3. Requirement
The battery should have no quality loss, no leakage, non -leakage, no short circuit, no rupture, no explosion, no fire.
The battery extrusion test machine is suitable for simulation of various types of batteries in use, transportation, storage or processing family waste, the battery is squeezed, The battery does not explode and cannot fire
