Battery high-altitude low-pressure simulation test chamber








Battery Altitude Simulation Test Chamber 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. It can automatically control the test cycle, monitor the air pressure change in the chamber during the whole process, and realize the automatic termination of the test.


Test Process
Battery and battery pack are stored for 6 hours at a pressure equal to or lower than 11.6kPa and an ambient temperature of (20±5)°C.

If the battery has no leakage, no exhaust, no disassembly, no rupture, and no fire, and every open circuit voltage of a test cell or battery pack after the test is not less than 90% of its voltage before the simulation test, which is considered qualified.
