Advanced Cold Climate & Icing Simulation Capability
The system provides highly controlled environmental conditions for automotive testing:
• Minimum temperature: ≤ -30°C
• Cooling performance: 25°C → -30°C within ≤ 2 hours
• Stable low-temperature holding capability at -30°C for extended test cycles
• Total test cycle time: ≤ 3 hours (with 3-ton full vehicle load)
Icing Simulation System
The chamber is equipped with a controllable icing mechanism:
• Localized vehicle surface icing simulation
• Manual or automatic spray icing system
• Formation of thin ice layers and ice accumulation effects
• Icing initiation time: ≤ 1 hour
This enables realistic reproduction of northern winter driving conditions, including snow accumulation, freezing rain, and surface icing.
Full Vehicle Test Chamber Design
To support complete vehicle validation, the system is engineered with large-scale internal dimensions:
• Internal size: 8.3m (L) × 4.3m (W) × 3.225m (H)
• External size: 10m (L) × 4.8m (W) × 3.75m (H)
This allows full-size passenger vehicles, including EV platforms, to be tested under dynamic environmental stress conditions.
Engineering Value for EV & Automotive Industry
As electric vehicles expand into cold climate markets, manufacturers face increasing challenges such as:
• Battery performance degradation at low temperatures
• Sensor and ADAS system icing interference
• Door and sealing system freezing
• Material contraction and structural stress under extreme cold
The TestEQ icing low-temperature chamber provides a controlled validation environment to detect and eliminate these risks early in the development cycle.
