The Battery High-Altitude (Low-Pressure) Simulation Test Chamber is

 designed in accordance with applicable standards, including GB/T 18332.2-2001, IEC 62133:2002, EN 62133:2003, UN 38.3, UL 2054, UL 1642, QC/T 743-2006, as well as the performance test specification for EV lithium-ion traction batteries under the national “863 Program” major project for energy-saving and new energy vehicles.

It is used to simulate the low-pressure storage condition (11.6 kPa) that batteries may encounter during high-altitude transportation, in order to evaluate battery performance and safety under such environments.

Main Features of the Equipment

The battery high-altitude (low pressure) simulation test chamber is designed in accordance with test standard requirements. The battery high-altitude simulation testing machine can quickly bring the sample to a low-pressure storage state, automatically control the test cycle, monitor the pressure changes inside the chamber throughout the process, and realize automatic test termination. The entire equipment consists of three parts: the outer chamber, the inner liner and the vacuum pumping system.

The outer chamber is made of high-quality thin steel plates with a powder-coated surface. The inner liner is made of stainless steel plates and has a cuboid inner cavity. The chamber door is equipped with a double-layer laminated glass observation window for easy viewing of items inside the chamber, and a long cylindrical door latch to adjust the distance between the door and the glass, ensuring the rubber sealing ring is compressed when the door is closed to prevent air leakage during vacuuming.

The vacuum pumping system is composed of a vacuum pump, a vacuum gauge, an electromagnetic vacuum valve and a balance port. The vacuum gauge adopted in this product features an optimized design for automatic and precise vacuum degree control, with customizable vacuum gauge functions and zone control method applied. The safety protection devices include earth leakage protection switch and fuse.
