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.

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 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.
