High altitude low pressure simulation test box for simulating plateau ambient air pressure
product description:
The test cabinet is designed for UL, EN, IEC and other standard
test requirements. It can reach the low pressure storage state of
the sample in a short time, and can automatically control the test
cycle. The whole process monitors the pressure change in the tank
to realize the automatic termination of the test. The simulated
battery and battery pack are stored for 6 hours at a pressure equal
to or lower than 11.6 kPa and an ambient temperature of (20 ± 5)
°C. If the battery has no leakage, no venting, no disintegration,
no cracking and no fire, and each The test circuit or battery pack
has an open circuit voltage of not less than 90% of its voltage
before the simulation test, which is acceptable.
Fulfill the standard:
