As battery technology continues to expand across electric vehicles, energy storage systems, consumer electronics, and renewable energy applications, manufacturers are facing increasing demands for battery safety, durability, and reliability validation. To address these challenges, LIB provides advanced environmental testing solutions designed to simulate extreme temperature conditions and verify battery performance according to global testing standards.

LIB Environmental Testing Solutions for Batteries support critical thermal testing requirements, including thermal cycling, thermal abuse, high-temperature endurance, low-temperature performance, and temperature shock evaluation. By combining precise temperature control, intelligent safety systems, and customized designs, LIB helps battery manufacturers and research laboratories improve product reliability and accelerate development.

【LIB Launches Advanced Thermal Cycling Test Equipment for Battery Safety Validation】

LIB Thermal Cycling Test Equipment is designed to simulate repeated temperature changes and evaluate battery durability, stability, and safety under harsh environmental conditions. The equipment supports a wide range of international standards, including IEC 62133, IEC 62660-2, IEC 61960, UL 1642, UL 2054, UL 2580, UL 2271, UL 1973, SAE J2464, SAE J2929, and IEC 60068-2-30.

For example, IEC 62133 Thermal Abuse Test requires fully charged battery cells to be placed inside a convection oven. The temperature increases at a rate of 5℃/min ± 2℃/min until reaching 130℃ ± 2℃, and the battery remains at this temperature for 30 minutes to verify that extreme heat does not cause fire or explosion.

For electric vehicle batteries, UL 2580 and UL 2271 Thermal Cycling Tests require battery systems to experience temperature changes from 85℃ ± 2℃ to -40℃ ± 2℃, simulating severe environmental temperature variations during actual vehicle operation.

UL 1642 Thermal Cycling Test Method

The UL 1642 standard is widely used for lithium battery safety evaluation. During temperature cycling testing, batteries are placed inside LIB Thermal Cycling Test Equipment and exposed to repeated high and low temperature conditions.

The testing procedure includes:

After testing, batteries are examined to confirm there is no explosion, fire, leakage, or abnormal deformation.

LIB Thermal Cycling Test Equipment provides accurate temperature control from -70℃ to +150℃, with temperature fluctuation within ±0.5℃ and temperature deviation within ±2.0℃, ensuring reliable test results according to UL and IEC requirements.

Safe Operation Principle of LIB Battery Thermal Testing Equipment

Battery testing requires not only accurate temperature control but also advanced safety protection. LIB Thermal Cycling Test Equipment combines intelligent control technology, multiple sensors, and safety protection systems to provide a reliable testing environment.

The equipment uses PID temperature control technology and PT100 Class A sensors to monitor temperature changes in real time. The programmable controller automatically adjusts heating and cooling performance to maintain stable testing conditions.

LIB battery testing chambers can be equipped with advanced safety functions, including:

① Independent temperature limit protection.

② Compressor overload protection.

③ Leakage protection.

④ Emergency shutdown systems.

⑤ Smoke detection and exhaust systems.

⑥ Optional automatic fire prevention and fire extinguishing systems.

These safety functions help laboratories reduce testing risks while maintaining accurate and stable battery evaluation.
