Battery high altitude low pressure simulation test chamber

This test case is designed for UL, EN, IEC and other standard test requirements. It can reach the low pressure storage state of samples in a short time, and can automatically control the test cycle, monitor the pressure changes in the whole process, and realize the automatic termination of the test. The simulated cells and batteries are qualified if they are stored for 6 hours at a pressure equal to or less than 11.6kPa and at an ambient temperature of (20±5) ℃, and if there is no leakage, exhaust, disintegration, rupture, or fire, and each experimental cell or battery has an open circuit voltage after the test that is not less than 90% of its voltage before the simulation.
