Temperature range
Power battery: -70℃ (low temperature lithium evolution protection) to +180℃ (thermal runaway simulation)
Rubber seals: -55℃ (low temperature embrittlement) to +150℃ (high temperature compression permanent deformation)
Electronic components: -40℃ (cold start verification) to +135℃ (vehicle ECU temperature limit)If you need more models about our test equipment, please reference our chamber-testing（.）com
Temperature variation rate
The power battery needs to meet the linear rise and fall of ≥15℃/min (simulating the sudden change of polar to desert environment)
Sensor parts require a gradient accuracy of ±0.5℃/min (to avoid signal drift caused by thermal shock)
Uniformity control
Working chamber space temperature difference ≤±1.5℃ (ISO 16750-4 Class 3 requirements)
3D circulating air duct design (adjustable wind speed 0.5-2.5m/s to meet the needs of different volume parts)
2. Environmental simulation and failure acceleration
Combined stress loading
Temperature cycle and humidity coupling: Verification of connector oxidation failure at 85℃/95%RH
Synchronous vibration stacking: Three-axis vibration table integration (according to SAE J2380 vibration spectrum)
