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 purposes

Battery low pressure (high altitude) simulation test, all tested samples are tested under a negative pressure of 11.6 kPa (1.68 psi)

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 1h

Battery module safety test Low air pressure (GB/T 31485-2015)

a) Battery module charging

b) 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 1h
