Explosion-Proof Battery Test Chamber

The DHT® Explosion-Proof Battery Test Chamber is a next-generation solution purpose-built for the safety testing of lithium batteries used in electric vehicles (EVs), energy storage systems (ESS), and other high-energy applications. As one of DHT® ’s advanced battery safety test chambers, it enables precise simulation of extreme conditions—such as temperature cycling, humidity fluctuation, and electrical stress—to assess battery performance and failure behavior.

Engineered as a fully featured explosion resistant test chamber, it supports rigorous evaluations of thermal runaway response, pressure buildup, and flame containment under abnormal scenarios. With multiple configurations—including single-layer, double-layer, and walk-in chamber options—it accommodates various battery sizes and test volumes with exceptional flexibility.

Compliant with international safety standards such as UN38.3, IEC 62660, and GB/T 31485, this chamber delivers trusted protection through reinforced construction, intelligent monitoring, and multi-stage safety mechanisms. As part of DHT’s portfolio of explosion proof test chambers, it is widely adopted by global battery manufacturers, EV OEMs, and third-party certification labs for safe, standardized, and repeatable battery reliability testing.

Benefits

Comprehensive Explosion-Proof Safety Measures: The chamber features a high-strength stainless steel enclosure combined with a multi-layer composite explosion-proof structure. It includes built-in pressure relief channels and flame-retardant materials to ensure controlled release of explosive shockwaves.

Intelligent Monitoring System: Equipped with multi-sensor real-time monitoring for pressure, temperature, smoke, and other parameters, the system triggers automatic power-off and emergency exhaust mechanisms upon detecting abnormal data.

Precise Temperature Control and Extreme Environment Simulation: Supports a temperature range from -70°C to +150°C with a heating and cooling rate exceeding 5°C/min, meeting the requirements for high and low-temperature cycling tests of batteries. An optional humidity module (20%–98% RH) simulates the impact of hot and humid environments on battery performance.

Customization and Compatibility: Functions can be expanded based on customer needs, such as adding charge/discharge testing modules and vibration testing modules. Available in various volumes (100L–1000L) and test chamber layouts, compatible with prismatic, cylindrical, and pouch batteries.

International Certifications and Long-Term Reliability: Certified by CE, UL, TÜV, and other international safety standards, in compliance with industry standards like IEC 62133 and SAE J2464. Key components (e.g., heaters, refrigeration systems) have a lifespan exceeding 100,000 hours, reducing operational and maintenance costs.
