  • Custom Environmental Test Chamber for Battery Packs

    Battery packs integrate multiple cells with a BMS and thermal controls for stable power. Key uses include EVs, energy storage, electronics, drones, and medical devices. Examples: Tesla’s 4680 and BYD’s Blade Battery.   The temperature and humidity testing of battery packs is a critical evaluation of their performance and reliability under varying thermal and hygrometric conditions. To simulate real-world operating environments, battery packs must undergo comprehensive testing across diverse conditions, including low temperature with low humidity (LT/LH), low temperature with high humidity (LT/HH), and high temperature with high humidity (HT/HH).   Based on actual case studies, this paper analyzes the technical requirements that a constant temperature and humidity test chamber must fulfill to conduct these assessments effectively.                                                       Key Technical Requirements for Test Chambers:   Temperature Range: Capable of achieving extreme conditions (e.g., -40°C to +85°C) with high stability (±0.5°C).   Humidity Range: Adjustable from 10% to 98% RH, ensuring precision (±2% RH).   Ramp Rates: Controllable temperature/humidity transition speeds (e.g., ≥1°C/min) to simulate rapid environmental changes.   Uniformity: Maintain consistent temperature (±1°C) and humidity (±3% RH) distribution within the workspace.   Data Logging: Real-time monitoring and recording of test parameters for compliance with standards (e.g., ISO 16750, GB/T 31467).   Safety Features: Explosion-proof design, leak detection, and emergency shutdown protocols for hazardous scenarios.   Battery Pack Environmental Testing Conditions 1. Temperature Testing High-Temperature Testing: Simulates vehicle operation or storage in hot climates. Test temperatures typically range from 45°C to 70°C, depending on standards (e.g., ISO, GB, or customer specifications). Test items include:           High-temperature storage          High-temperature cycling          High-temperature discharge   Low-Temperature Testing: Simulates vehicle operation or storage in cold climates. Test temperatures typically range from -40°C to -20°C, depending on standards. Test items include:          Low-temperature storage          Low-temperature startup          Low-temperature cycling          Low-temperature discharge   Thermal Shock Testing: Simulates rapid temperature fluctuations (e.g., -40°C ↔ 70°C) to evaluate the battery pack’s resistance to extreme thermal stress.   Thermal Runaway Testing: Simulates internal/external short circuits to assess the effectiveness of the battery pack’s thermal management and safety mechanisms, preventing explosions or fires.   2. Humidity Testing Damp Heat Cycling Test: Simulates high-temperature, high-humidity environments (e.g., 40°C / 95% RH) to evaluate corrosion resistance and sealing performance.   3. Salt Spray Testing Salt Fog Corrosion Test: Simulates high-salinity coastal environments to verify the battery pack’s corrosion resistance.   4. Waterproof Testing Water Ingress Test: Simulates water exposure (e.g., immersion, rain) to validate waterproofing performance (evaluated by IP protection rating).   5. Dustproof Testing Dust Ingress Test: Simulates high-dust environments (e.g., deserts) to verify sealing integrity.   6. Low-Pressure Testing Altitude Simulation Test: Simulates atmospheric pressure changes at different elevations to assess battery pack adaptability.   Technical Specifications for Constant Temperature & Humidity Test Chamber (Compliant with customer requirements)   Chamber Dimensions Internal dimensions (W×D×H): 3000 × 2000 × 2000 mm   Functional Requirements 1.Temperature Range: -60°C to +150°C   2.Heating Rate: ≥1°C/min (average, under load: 1T, 5kW heat output) from -40°C to +125°C   3.Cooling Rate: ≥1°C/min (average, under load: 1T, 5kW heat output) from +125°C to -40°C   4.Temperature Resolution: 0.01°C   5.emperature Fluctuation: ≤±0.2°C (no load)   6.Temperature Deviation: ≤±2°C   7.Temperature Uniformity: ≤2°C (no load)   8.Continuous Low-Temperature Operation: 1000 hours at low temperature without frost/icing (requires dry air system)   9.Humidity Resolution: 0.1% RH   10.Humidity Fluctuation: ≤±2.5% RH   11.Humidity Deviation:        ≤+3% RH (when >75% RH)         ≤±5% RH (when <75% RH)   12.Extended Operation Capability:        Low-temperature & low-humidity: 240 hours        High-temperature & low-humidity: 240 hours   Key Enhancements & Scientific Rigor 1.Standard References: Added implicit compliance with ISO, GB, and IP standards for credibility.   2.Precision Metrics: Specified resolution, uniformity, and deviation to meet engineering demands.   3.Safety & Reliability: Highlighted frost prevention (dry air system) and long-duration testing capability.   4.Clarity & Structure: Organized into logical sections for readability while maintaining technical accuracy.   To meet the rigorous demands of battery pack environmental testing, our advanced constant temperature and humidity test chambers are engineered to deliver precision, reliability, and compliance with global standards.   Why Choose Our Environmental Test Chambers? ✅ Wide Temperature Range: -70°C to +150°C for comprehensive high/low-temperature testing, including thermal shock. ✅ Rapid Temperature Transition: ≥1°C/min heating/cooling rates under load (1T, 5kW heat output). ✅ High Humidity Precision: 10%–98% RH with ±2.5% RH fluctuation and 0.1% resolution for accurate damp heat cycling. ✅ Stable Long-Duration Operation: 1000+ hours at extreme low temps (anti-frost dry air system included). 240+ hours in low-humidity conditions (both high & low temp). ✅ Uniformity & Accuracy: ≤±0.2°C temp fluctuation (no load) ≤2°C spatial uniformity. ✅ Large Testing Capacity: 3000×2000×2000mm (W×D×H) internal workspace of Walk-in Climate Test Chamber for full-scale battery pack evaluations. ✅ Safety & Durability: Designed for thermal runaway prevention, salt fog, waterproof (IP-rated), and dustproof testing.                                  

  • New Energy

    Based on new technologies and new materials, we will modernize the development and utilization of traditional renewable energy. We will replace fossil energy with renewable energy that has limited resources and pollutes the environment. Among them, solar energy, wind energy, biomass energy, tidal energy, geothermal energy, hydrogen energy and nuclear energy are the key development energy determined by the United Nations. The collectors and converters of new energy often need to be placed in the outdoor environment, so the detection of these equipment materials and design is an important part.    

  • Semiconductor

    Semiconductor products are often used in high-end electronic equipment, such as medical devices and communication equipment, so its quality and reliability can not be ignored, reliability testing is through a series of experiments and analytical means to evaluate the reliability,stability and life of semiconductor devices under specific conditions, is an important means to ensure product quality and stability, and also the basis of customer trust and satisfaction. Therefore, the establishment of scientific and rigorous semiconductor reliability test standards is crucial to the development of the semiconductor industry.
