Batteries used in electric vehicles, renewable energy storage, and portable devices must endure sudden and extreme temperature changes during real-world operation, transport, and storage. Without proper stress testing, these rapid shifts can cause hidden defects, shorten battery lifespan, or even trigger safety risks. Thermal shock testing has therefore become a critical step in ensuring battery durability, performance, and consumer safety.
To address these challenges, LIB offers Two-Zone and Three-Zone Thermal Shock Chambers designed specifically for battery reliability testing. With extreme temperature ranges from +220 °C to –70 °C, rapid transition times of <3 seconds, and recovery in under 5 minutes, LIB chambers provide the precision, repeatability, and safety that modern battery manufacturers require. Whether testing small cells or full battery packs, LIB delivers dependable solutions that replicate the harshest conditions batteries may face.
【Reliable, Precise, and Safe Thermal Shock Testing by LIB's Two-Zone and Three-Zone Shock Chambers】
When it comes to battery reliability, the ability to simulate sudden and extreme temperature changes is essential. LIB's Two-Zone and Three-Zone Thermal Shock Chambers are engineered specifically to replicate real-world stress conditions that batteries encounter during operation, transport, and storage.

Two-Zone Thermal Shock Test Chambers move the battery samples in a basket vertically between hot and cold chambers. Transfer occurs in less than 3 seconds, with temperature recovery achieved in under 5 minutes. These specifications ensure accelerated testing cycles without compromising accuracy.
Three-Zone Thermal Shock Test Chambers keep the test samples stationary in the middle test room. Hot or cold air is redirected through pneumatic dampers, allowing temperature shocks from +220 °C to –75 °C without physically moving the sample. This design is ideal for large, heavy, or fragile batteries, where safe handling is critical.
Both systems employ SUS304 stainless steel interiors for corrosion resistance, anti-condensation systems to prevent ice buildup, and multi-layer safety interlocks that protect equipment and operators.

What Makes LIB's Thermal Shock Chamber Ideal for Reliable Battery Testing?
LIB has refined its chambers with features that directly address the challenges of modern battery testing-delivering extreme performance, uncompromised safety, and operational efficiency.
Extreme Performance Range
- Test temperature range: +220 °C down to –70 °C (optional low-type designs extend to –86 °C).
- Ramp rates adjustable: ≥5 °C/min, ≥10 °C/min, or ≥15 °C/min.
- Tight deviation control: ±0.5 °C fluctuation, ensuring accurate repeatability across the entire test chamber.
- Uniform airflow system: Bidirectional circulation keeps chamber variation within ±0.5 °C, eliminating hot or cold spots.
