As electric vehicles, energy storage systems, and high-capacity lithium-ion batteries continue to scale globally, safety testing has become more critical than ever. Among all battery safety evaluations, thermal runaway testing stands out as the most demanding and high-risk procedure.
A single uncontrolled thermal event can lead to fire, explosion, toxic gas release, and catastrophic system failure. For manufacturers and certification laboratories, conducting thermal runaway experiments is no longer optional — it is mandatory for compliance and market access.
However, performing this test safely requires far more than a standard environmental chamber. It demands a purpose-built battery test chamber engineered specifically to withstand extreme conditions. LIB industry provides a comprehensive solution through its advanced Battery Thermal Runaway Test Chamber and complementary TH series chambers.
Thermal runaway occurs when internal chemical reactions generate heat faster than it can dissipate, triggering a self-accelerating chain reaction. Once initiated, temperatures can exceed 800°C within seconds.
International standards such as:
IEC 62133
UL 1642
UL 2580
SAE J2464
UN 38.3
require lithium-ion batteries to undergo abuse conditions including controlled heating, overcharge, short circuit, or mechanical damage to evaluate failure behavior.
For EV battery packs, energy storage modules, and research cells, demonstrating controlled thermal behavior is essential for certification, transportation approval, and insurance validation. This makes the Battery Thermal Runaway Test Chamber a cornerstone of modern battery development laboratories.
LIB industry also supports thermal runaway experiments for all EUCAR hazard levels (0–7), ensuring that the chamber accommodates a full spectrum of testing needs.
A true thermal runaway test environment must address three core challenges: extreme heat, explosive pressure, and hazardous gas management.
The chamber must provide:
Programmable heating rates (up to 5, 10, 15°C/min)
Wide temperature range (-70℃ to +150℃, up to +170℃ if required)
Temperature stability within ±0.5℃
Rapid thermal cycling capability
Precision is critical. Inconsistent heating may invalidate test results or fail to trigger representative failure modes. LIB industry battery test chambers use nickel-chromium alloy electric heaters combined with intelligent control to ensure uniform temperature distribution.
During thermal runaway, batteries may:
Burst violently
Release high-pressure gases
Produce flame jets
Fragment internally
A conventional chamber is not designed for these mechanical stresses. LIB industry chambers employ a three-level explosion-proof design:
Chamber reinforced with 6mm SUS304 stainless steel
Pressure relief channel
Observation window with explosion-proof mesh
Explosion-proof lock and hinge chain
This ensures containment during high-energy failure events, while allowing visual monitoring. Movable shelving and customizable chamber volume support cylindrical, prismatic, and soft pack batteries of various sizes.
Thermal runaway often results in open flame and sustained combustion. LIB battery test chambers integrate:
Spray system to cool and prevent fire propagation
Automatic fire suppression
Emergency stop and remote shutdown
Smoke detection (alarm threshold >300PPM)
Pressure probe monitoring (>200KPa)
This combination allows real-time response to fire or smoke events while maintaining personnel safety.
Lithium-ion battery failure can release:
Carbon monoxide (CO)
Hydrogen (H₂)
Hydrogen fluoride (HF)
Flammable electrolyte vapors
Without proper exhaust systems, laboratory personnel and equipment are at serious risk. LIB battery test chambers provide:
High-efficiency smoke exhaust system
Forced ventilation for toxic gas removal
Optional gas analysis interface
Compliance with international laboratory safety standards
This ensures laboratory safety while maintaining reliable experimental results.
Some laboratories attempt to conduct thermal abuse tests in modified environmental chambers. This approach introduces significant risks:
Structural deformation or rupture during explosion
Fire spreading outside the chamber
Toxic gas leakage
Incomplete data acquisition
Non-compliance with certification standards
Beyond equipment damage, inadequate testing infrastructure can compromise personnel safety and invalidate regulatory approval. A properly engineered Battery Thermal Runaway Test Chamber eliminates these risks by integrating thermal control, explosion resistance, fire protection, and exhaust management into one system.
LIB industry specializes in high-performance battery test chamber systems engineered specifically for lithium-ion safety testing. Rather than modifying general-purpose equipment, LIB industry develops integrated safety solutions for high-risk battery abuse experiments.
Battery safety regulations continue to tighten worldwide. LIB industry designs its Battery Thermal Runaway Test Chamber systems to support testing aligned with:
IEC 62133
UL 1642
UL 2580
SAE J2464
UN 38.3
By ensuring structural integrity, data reliability, and environmental safety, LIB industry helps laboratories accelerate certification approval with confidence.
