  • The humidity range of 10% to 95% RH, with an accuracy of ±2% RH, allows for a comprehensive evaluation of the effect of moisture on EV components. High humidity can affect the corrosion resistance of battery terminals and the integrity of the battery casing, while low humidity can cause drying and cracking of certain materials. The ability to precisely control the humidity level is essential for understanding how these components respond to different moisture environments.
• Testing Volume and Payload Capacity
  • The chamber offers a customizable testing volume, typically ranging from 1 m³ to 5 m³, depending on the specific model. The payload capacity can handle a significant amount of test samples, with a maximum capacity of up to 2000 kg, allowing for the testing of multiple cells, modules, or packs simultaneously.
• Data Sampling Frequency and Resolution
  • The data acquisition system samples data at a frequency of up to 200 Hz, providing a highly detailed record of the temperature, humidity, and other environmental parameter changes. The resolution of the temperature data is 0.1°C, the humidity data is 0.1% RH, and other relevant data also have high precision. This high-resolution data is invaluable for identifying even the slightest trends and potential failure points, allowing for a more accurate assessment of product performance.

4. Product Functions
