As the electric vehicle (EV) market expands into high-altitude regions and the aerospace industry transitions to more electric aircraft (MEA), the demand for Battery Altitude Chambers has surged. Testing batteries at low pressures is no longer a niche requirement but a critical safety protocol under UN38.3 and UL 1642 standards.
Batteries operating in high-altitude environments (above 3,000 meters) experience significantly reduced heat dissipation efficiency due to thinner air. Our chambers simulate these precise conditions to ensure thermal management systems can handle the stress without going into thermal runaway.
One critical "Information Gain" factor in our research is the study of electrolyte leakage and cell pouch swelling under vacuum. Our custom altitude chambers provide high-speed visual recording and pressure sensors to detect the exact millibar at which structural failure occurs.
Dongguan Huanyi Instruments Technology Co., Ltd. leverages the world's most complete industrial supply chain. By integrating R&D with digital sheet metal centers and ERP-driven production, we offer a 30% faster lead time than Western competitors without compromising on the precision of simulation.
Our facility uses automated laser cutting and wood processing to minimize waste. Every component, from the compressor to the PLC controller, is sourced from internationally renowned brands like Bitzer, Tecumseh, and Schneider.
With established offices in Jiangsu, Xi'an, Chongqing, Shanghai, and Beijing, we maintain a domestic network that supports our global export capabilities to Southeast Asia, Europe, and the United States.
Established on March 20, 2007, covering 6,022 square meters, Dongguan Huanyi is a high-tech enterprise integrating R&D, production, sales, and after-sales service. We are proud participants in drafting national standards for environmental simulation equipment.
"Customer-centric, quality-guaranteed, honesty-based, and innovation-oriented". We have cultivated a team with over 20 years of expertise in testing instrumentation.
Our factory display includes finished product display libraries, office sales teams, and dedicated production departments. We use ERP systems to monitor every step of the process.
