Product introduction The high-altitude low-pressure test machine is used to simulate the detection of battery leakage, shell rupture, fire or explosion in a test environment with a constant temperature or variable temperature (ie high altitude). Test purpose and description Test purposes Battery low pressure (high altitude) simulation test, all tested samples are tested under a negative pressure of 11.6 kPa (1.68 psi) Test description Single battery safety test Low air pressure (GB/T 31241 -2014) a) Single battery charging b) In the low-pressure tank of the single-cell battery method, the air pressure in the test chamber is adjusted to 11.6kpa, the temperature is room temperature, and it is allowed to stand for 6h. c) Observation 1 h Battery module safety test Low air pressure (GB/T 31485-2015) a) Battery module charging d) The battery module is placed in a low-pressure test chamber, and the air pressure in the test chamber is adjusted to 11.6kpa, the temperature is room temperature, and it is allowed to stand for 6h. c) Observation 1 h
