The high-altitude and low-pressure simulation test chamber for batteries is designed according to standard requirements to meet the requirements GB/T 18332.2-2001，IEC 62133:2002,EN 62133:2003，UN38.3，UL 2054,UL 1642，QC/T 743－2006 And the performance testing specifications for lithium-ion power batteries for electric vehicles, a major project of the "863 Program" for energy conservation and new energy vehicles; Simulate the storage state of 11.6kPa in a low-pressure environment that may occur during high-altitude transportation of batteries. The main features of the high-precision low-pressure simulation testing machine equipment are:

The battery high-altitude (low-pressure) simulation test chamber is designed according to the requirements of the test standards. The battery high-altitude simulation test machine can reach the low-pressure storage state of the sample in a short period of time, automatically control the test cycle, monitor the pressure changes inside the chamber throughout the process, and achieve automatic termination of the test. The entire device consists of three parts: the box, the inner container, and the vacuum system. The box is made of high-quality thin steel plate and the surface is treated with spray coating. The inner liner is made of stainless steel plate, and the shape of the inner cavity is rectangular; The box door adopts a double-layer laminated glass inspection window for easy observation of the items inside the box. At the same time, a long cylindrical door buckle is used to adjust the distance between the door and the glass, so that the box door can be tightly pressed against the rubber seal ring after closing, ensuring no air leakage during air extraction. The vacuum pumping system consists of a vacuum pump, a vacuum gauge, an electromagnetic vacuum valve, and a balancing port. The vacuum gauge design used in this product automatically controls the vacuum degree. The control of vacuum degree can be adjusted by setting the functions of the vacuum gauge. Adopting regional control methods. The protective device adopts leakage protection switches, fuses, etc. High precision low-pressure simulation testing machine technology
