Two explosion-proof test boxes for batteriesPerformance and Configuration

• Temperature range: A: -20 ℃~150 ℃ B: -40 ℃~150 ℃ C: -60 ℃~150 ℃ D: -70 ℃~150 ℃
• Temperature uniformity: ≤ 2.0 ℃ (when unloaded)
• Temperature fluctuation: ± 0.5 ℃ (when unloaded)
• Temperature deviation: ± 2.0 ℃ (when unloaded)
• Heating rate: 1.0-3.0 ℃/min
• Cooling rate: 0.7-1.0 ℃/min
• Outer box material: double-sided galvanized high-quality cold-rolled steel plate, surface treated with electrostatic spraying, plate thickness t=1.5mm
• Inner box material: stainless steel plate (SUS304-CP 2B ground processing), plate thickness t=1.0mm
• Insulation material: 120mm hard polyurethane foam insulation layer
• Explosion proof design: 1. Explosion proof chains are installed on the front and top pressure relief doors of the box; 2. The connection between the explosion-proof door and the box body adopts reinforced hinges, and the door lock adopts a strong flat lock; 3. The observation window is equipped with an explosion-proof cover to prevent glass splashing from injuring people; 4. The top of the box is equipped with an automatic explosion-proof pressure relief port, which will automatically pop open to release pressure once overpressure is detected
• Controller: Imported "Youyi Control" brand temperature and humidity instrument
• Refrigeration system: French "Taikang" fully enclosed air-cooled compressor refrigeration method
• Temperature sensor: high-precision Pt100 platinum resistance temperature sensor
• Pressure relief hole: equipped with an electric pressure balancing device to maintain a slight positive pressure in the range of 0-50Pa inside the box under any circumstances
• Safety detection and fire protection devices: 1) Temperature detection and alarm: equipped with 4 temperature detection sensors for test samples, the temperature sensors can be linked with the control system to achieve alarm and shutdown functions in case of high temperature or temperature runaway; 2) Smoke detection and alarm: equipped with smoke detection sensors, capable of identifying smoke when the battery system burns, and can promptly alarm and shut down in case of a fire; 3) Spray system: equipped with a spray system, it can timely judge the combustion status of the battery system and take corresponding linkage measures in a timely and effective manner to prevent the spread of accidents.
• Safety protection: compressor low/overload/high pressure alarm, fan motor overload, emergency stop switch, sound and light alarm, overall equipment timing, water shortage, short circuit, phase loss, overheating, leakage protection, etc
• Power supply voltage: AC380V ± 10% 50Hz
• Total power: approximately 11.0kW
