Batteries are increasingly used in a wide range of applications, from consumer electronics to electric vehicles and large-scale energy storage systems. During operation, they encounter diverse environmental stresses such as extreme temperatures, humidity, mechanical vibration, and corrosive conditions. Ensuring battery reliability, safety, and long service life is therefore essential for manufacturers and end users alike.
LIB Industry offers a comprehensive portfolio of environmental chambers designed specifically for battery testing. Our solutions include Temperature Chambers, Constant Temperature & Humidity Chambers, Thermal Shock Chambers, Vibration & Combined Chambers, Explosion Proof Chambers, and Salt Spray/Corrosion Chambers. Each environmental chamber is engineered to meet international standards while providing precise control over test parameters, helping engineers and researchers optimize battery performance and durability.
Test Type | Recommended Equipment | Key Parameters / Considerations |
Room Temperature Charge/Discharge | Temperature Chamber | −20–60℃, ±0.5℃ accuracy, supports cable passthrough |
High-Temperature Storage | Constant Temperature Chamber | +60–85℃, long-term stability, exhaust interface |
Humidity & Damp Heat Aging | Constant Temperature & Humidity Chamber | 40–85% RH / 40℃, anti-condensation design |
Thermal Shock | Thermal Shock Chamber | Ramp rate ≥10℃/min, multiple cycles |
Transportation Vibration | Vibration / Combined Chamber | Random vibration 3–10g, temperature + vibration combination |
Thermal Runaway Safety | Explosion / Safety Chamber | Exhaust system, gas detection, fire suppression interface |
Salt Spray / Corrosion | Salt Spray / Corrosion Chamber | 1–5% NaCl, spray duration 24–1000h, 35±2℃ |
Batteries are highly sensitive to environmental conditions. Temperature fluctuations can accelerate capacity degradation, while high humidity may cause condensation, compromising both performance and lifespan. For example, a lithium-ion cell stored at 60℃ may degrade faster if temperature uniformity is poor, or if 85% relative humidity leads to moisture accumulation. Accurate testing under controlled conditions ensures reliability.

Applications
Single-cell testing for capacity and efficiency verification
Module cycling and full-pack aging studies
Reliability assessment of different material combinations under thermal and humid stress
Multi-point data acquisition ensures precise monitoring
High-temperature and humid environments also introduce mechanical stress on batteries, naturally leading into vibration and transportation reliability testing.
Thermal Shock Test → Two-zone / three-zone thermal shock test chamber
When the battery transitions from a low-temperature environment to a high-temperature environment (or vice versa), the internal stress changes may cause the shell to deform, the seal to fail, or the performance to deteriorate. The cold and heat shock test is used to evaluate the tolerance limits of the battery structure and materials.

Applications
EV battery pack transportation simulation
Stacked energy storage battery shipments
Connector and terminal fatigue testing under vibrational stress
Even when mechanical robustness is validated, batteries exposed to outdoor or marine environments may face corrosive stress, necessitating salt spray and corrosion testing.
In coastal or offshore environments, salt-laden air can corrode battery housings and terminals, reducing lifespan. Salt spray testing reproduces these conditions to verify durability.
Test Type and Recommended Equipment
Salt Spray Corrosion → Salt Spray Chamber/Cyclic Corrosion Chamber

Applications
Outdoor energy storage systems
Offshore photovoltaic storage systems
EV battery pack enclosure and terminal corrosion resistance testing
Even with corrosion resistance validated, high-risk operational scenarios—such as overcharge, short-circuit, or mechanical abuse—require safety and thermal runaway testing.
Battery thermal runaway is a critical safety concern. Overcharge, short circuits, or nail penetration can trigger uncontrollable reactions, endangering personnel and equipment. Explosion proof test chambers provide a controlled environment to safely test these scenarios.
