Battery Altitude Simulation Test Chamber

UN38.3 UL1642 High Altitude Low Pressure Simulation Test Chamber for Sale

Lithium-ion Battery Altitude Simulation Test Chamber is also called the high altitude low pressure simulation test chamber. It is used to simulate air transport under low-pressure conditions.

Specifically, the device reproduces an unpressurized cabin of an aircraft flying at high altitude and allows samples to be placed in this environment. After a specified period of time, the sample is observed to determine its conformity.

The altitude test chamber is one of the vital battery safety testing machines. If you are looking for other lithium-ion battery safety testing devices, please feel free to reach us for more.

The test space features an enclosed vacuum chamber. When its internal air pressure is reduced to a specific value, the environment in which the sample is located is equivalent to that at the altitude corresponding to the air pressure value. Lithium-ion cells or batteries usually require a test air pressure of 11.6 KPa, equivalent to an altitude of 15,000 meters. Our high altitude simulation test chamber can provide air pressure ranging from 5 KPa to 101.3 KPa to meet your different testing requirements.

The control area of our high altitude low pressure test chamber is equipped with a high-definition LCD touch screen controlled by PLC man-machine interface. It is user-friendly and allows you to enter the desired simulated air pressure or altitude. You are also available to preset the pressure hold time according to the test requirements. The real-time air pressure and altitude will be displayed on the screen for you to check. The altitude test chamber has a built-in high-quality vacuum pump, which effectively reduces the noise during operation and improves the efficiency of vacuuming. The pump is stable, reliable, and easy to maintain. The altitude simulation tester will automatically stop after the preset test time is achieved.

In addition to verifying the safety and reliability of the battery, this altitude test chamber can also be used for reliability testing of other products and devices. It can be powered during the test of the product to verify whether it can work normally in a high-altitude environment. For specimens that need to be energized during testing, we install wiring posts on the sides of the vacuum chamber so that power or signal lines can be routed into the vacuum chamber and sealed without leaking the vacuum.

Besides regular models, we are capable of producing different chamber dimensions and thicknesses to match your sample sizes and capacities. If you are interested in this machine, please tell us your sample specifications and required features first. So that, we can recommend matching models to better meet your testing needs.

Why do High Altitude Simulation Test on Lithium-ion Batteries?

First of all, as we know, the UN38.3 certificate is the passport for all lithium metal and lithium-ion batteries or products containing lithium metal or lithium-ion batteries to board a cargo aircraft for air transportation. High altitude low-pressure test is one of the essential test items in the UN38.3 test standard.

Secondly, lithium-ion batteries’ application is becoming more extensive, especially since many portable electronic devices such as mobile phones, laptops, wearable watches, etc., basically use lithium-ion batteries as power sources. When we fly, we inevitably carry these devices with us or store them separately in the cargo hold of the aircraft along with other luggage. Therefore, we need to carry out relevant safety tests on the lithium-ion batteries in these products in advance to ensure that they can be transported at such a high altitude safely and to verify whether these devices can still work normally after being stored in the low-pressure environment for a period of time.

Methods & Requirements for the High Altitude Simulation Test of Lithium-ion Batteries and Cells

Put the test cells or batteries into the inner chamber of the altitude simulation tester at an ambient temperature of (20±5)℃ and then close the door.
Power on and use the touch screen to preset the test pressure of 11.6 KPa and pressure hold time of 6 hours, then start the test.
When the time is up, the equipment will automatically stop. Turn on the pressure relief switch. After the pressure inside the chamber is released, open the door to observe the change in the sample.
Specimens are qualifiedif there is no leakage, no venting, no disassembly, no rupture and no fire and if the open-circuit voltage of each test cell or battery after testing is not less than 90% of its voltage immediately before this process. The requirement relating to voltage is not applicable to test cells and batteries at fully discharged states.
