Stress screening tests for battery modules, battery packs, battery assemblies and complete batteries. Lithium-ion battery packs or systems are placed in an alternating temperature environment of (-40 ± 2)℃ to (85 ± 2)℃, with the transition time between the two extreme temperatures within 30 minutes. The test subjects are maintained at each extreme temperature for 8 hours, and the cycle is repeated 5 times.
Application scenario: Covering the full life cycle testing of batteries
Battery test chambers are widely used in various stages of battery research and development, production, and quality inspection. During the battery R&D phase, by simulating different environmental conditions such as high temperature, low temperature, and high humidity, the charging and discharging performance, cycle life, and other key indicators of batteries under different environments are tested, providing data support for battery R&D and improvement.

Battery Temperature Test Chamber Installation Requirements
I. Site Requirements
1.1 Space Dimensions
Installation Space: A maintenance space of ≥500mm should be reserved around the equipment (front, back, left, and right), and ≥300mm at the top (for heat dissipation and maintenance).
Door Opening Direction: The chamber door should face an open area to avoid blocking passageways or colliding with other equipment.
Load Capacity: The floor load capacity should be ≥1.5 times the total weight of the equipment (e.g., for a 500kg equipment, the floor load capacity should be ≥750kg).
1.2 Environmental Conditions
Temperature Range: The installation environment temperature is recommended to be 5℃ to 35℃ (additional ventilation or air conditioning may be required in extreme high temperatures).
Humidity Requirement: Relative humidity ≤80% (no condensation), and dehumidification equipment should be installed in high-humidity areas.
Cleanliness: Avoid environments with dust and corrosive gases (such as acid/alkali vapors). Air filtration devices should be installed if necessary.
1.3 Floor Requirements
Levelness: The floor flatness error should be ≤2mm/m² (calibrated with a laser level).
Vibration Isolation: Keep away from large motors, stamping equipment, and other vibration sources. Vibration isolation pads should be installed if necessary.
Drainage: The floor should have a drainage slope of 1% to 2% to facilitate the drainage of condensation water or leaked liquids.
Electrical Requirements
2.1 Power Supply Configuration
Voltage Range: ±10% of the equipment's rated voltage (e.g., AC 380V ± 10%). A voltage stabilizer is required when voltage fluctuation exceeds ±5%.
Power Demand: Total power = equipment's nominal power × 1.2 (considering peak starting current), with separate circuit supply.
Grounding Requirements: Independent grounding wire (grounding resistance ≤ 4Ω), avoiding shared use with lightning protection grounding.
2.2 Wiring Specifications
Cable Specifications: Select copper core cables based on equipment power (e.g., ≥ 4mm² three-phase five-wire system).
Circuit Breaker Protection: Install overload, short circuit, and leakage protection devices (rated current ≥ 1.5 times the equipment's maximum current).
Phase Balance: For three-phase equipment, ensure three-phase current balance (error ≤ 15%).
