Altitude 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 box during the whole process, and
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 11.6kPa 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 The 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.
