Battery High Altitude Low Pressure Test Chamber for UN38.3 Lithium Battery Safety Testing
A precision-engineered Battery Testing Equipment designed to simulate extreme high-altitude low-pressure environments (≤11.6kPa), ensuring lithium batteries meet global transport and safety standards such as UN38.3, IEC62133, and UL1642.
Product Overview
In global battery logistics and application scenarios, altitude simulation is one of the most critical safety validation steps. Batteries transported by air or used in high-altitude regions must remain stable under reduced atmospheric pressure.
The Battery High Altitude Low Pressure Test Chamber developed by HongCe replicates these real-world conditions with precision vacuum control, allowing manufacturers to identify risks such as leakage, rupture, or fire before market release.
This system automatically reaches and maintains a low-pressure environment (typically 11.6kPa) and monitors the entire test cycle—ensuring compliance, safety, and reliability across industries.
As a source factory, HongCe provides not only equipment—but a complete reliability solution backed by engineering expertise and responsive global service.
