The Battery High Altitude Low Pressure Test Chamber is a specialized piece of equipment designed to simulate the effects of high altitude conditions on lithium batteries, crucial for assessing their performance and safety under low pressure environments.This chamber is engineered to replicate the low pressure and reduced atmospheric conditions found at high altitudes, which can significantly impact battery performance and safety . It achieves this by subjecting batteries to pressures as low as 11.6kPa, equivalent to the atmospheric pressure at high altitudes, to test for potential explosions, fires, or leakages .
This chamber is an indispensable tool for the aviation, electric vehicle, and battery manufacturing industries, providing a controlled platform to evaluate battery performance under simulated high altitude conditions.
1. Rapid Low-Pressure Simulation: Capable of quickly achieving the low-pressure storage state required for samples, this chamber can replicate the pressure conditions equivalent to high altitudes in a short time .
2. Automated Test Cycle Control: Equipped with automatic controls that monitor air pressure changes throughout the testing process and can terminate the test automatically .
3. Safety Compliance：Designed to meet various international standards such as UN 38.3, IEC 62133, UL 1642, and GB/T standards, ensuring comprehensive testing for different applications .
4. Construction and Design: The interior is crafted from 304 stainless steel with Teflon insulation on the bottom, and the box features an air vent, pressure relief port, and internal lighting .
5. Safety Features: The chamber includes a single door with a safety limit switch and an explosion-proof chain, ensuring that the door is closed before operation, which is crucial for personnel safety .
6. Convenience for Testing: A 50mm diameter test hole on the side of the device facilitates the insertion of temperature, voltage, and current collection lines for comprehensive data acquisition .
7. Pressure and Vacuum Control: The chamber offers a pressure range of 0.5 to 100Kpa, with a common test air pressure of 11.6 Kpa, and features a digital vacuum meter for precise control and display of vacuum levels .
8. Timer and Display: Equipped with an LED digital timer that can be set within a range of 0-99 hours and 99 minutes, and a two-layer tempered glass observation window with a size of 250x250mm, complete with a stainless steel mesh for safe observation .
9. Efficiency and Precision: The chamber maintains a pressure fluctuation of ≤5%, ensuring the accuracy and reliability of the tests .
10. Power and Dimensions: Operates on an AC220V, 50HZ, 2.2KW power supply with internal and external dimensions that accommodate various battery sizes for testing .
