1. Product Name and Purpose

2. Product Features

• Robust and Insulated Chamber Structure
  • The chamber is constructed with a heavy-duty framework, typically made of high-strength steel or aluminum alloys, providing exceptional durability and resistance to the rigors of continuous testing. The walls are insulated with advanced materials that minimize heat transfer and maintain highly accurate temperature and humidity levels. The door is engineered with a reliable sealing mechanism and a large viewing window, allowing operators to closely monitor the testing process without compromising the integrity of the internal environment. The interior is designed with smooth, non-reactive surfaces to prevent any contamination or interference with the test samples.
• Precision Temperature and Humidity Control System
  • At the core of the chamber's capabilities lies a sophisticated temperature and humidity control system. It can achieve a wide temperature range, typically from -40°C to +80°C, with an accuracy of ±0.3°C. The humidity control range extends from 10% to 95% relative humidity, with an accuracy of ±2% RH. The system utilizes high-performance refrigeration units, powerful heaters, and advanced humidifiers and dehumidifiers, all coordinated by a precise PID controller. Multiple sensors are strategically placed throughout the chamber to provide real-time feedback, enabling the control system to make rapid and accurate adjustments to maintain the desired environmental conditions.
• Programmable Testing Sequences
  • The chamber is equipped with a highly programmable control panel that allows for the creation and execution of complex testing sequences. Operators can easily set up temperature cycling, humidity cycling, and combinations of both, simulating various real-world scenarios such as seasonal changes, extreme weather conditions, and different geographical locations. Additionally, the chamber can be programmed to introduce other environmental factors like altitude simulation and corrosive gas exposure, providing a comprehensive evaluation of the components' performance and durability.
• Intuitive Control Panel and Data Acquisition Interface
  • The user-friendly control panel simplifies the operation and parameter setting. It features a clear and intuitive interface that enables operators to adjust temperature, humidity, test durations, and other parameters with ease. The control panel also provides real-time displays of the current environmental conditions, as well as any alarms or warnings. The chamber is integrated with a comprehensive data acquisition system that records all relevant test data, including temperature and humidity histories, rate of change of environmental parameters, and any observable changes in the test samples. The data can be stored in a built-in memory or exported to external storage devices for further analysis. The system can also generate detailed test reports in various formats, facilitating easy documentation and sharing of results.
• Safety Features and Alarms
  • To ensure the safety of operators and the integrity of the testing process, the chamber is equipped with a range of safety features. These include over-temperature and over-pressure protection, emergency stop buttons, and alarms for abnormal temperature fluctuations, humidity levels, or equipment malfunctions. The safety features are designed to prevent damage to the chamber, the test samples, and the surrounding environment, providing peace of mind during the testing operation.

3. Specific Parameters

• Temperature Range and Accuracy
  • With a temperature range of -40°C to +80°C and an accuracy of ±0.3°C, the chamber can subject EV components to a wide spectrum of temperatures. This is crucial for testing the performance and durability of cells, modules, and packs in extreme cold and hot conditions, such as during winter driving or in high-temperature environments. The accurate temperature control ensures that the test conditions are precisely maintained, providing reliable and repeatable results.
• Humidity Range and Accuracy
  • 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

• Accurate Simulation of Environmental Conditions
  • The primary function of the chamber is to provide a precise and reliable simulation of the temperature, humidity, and other environmental conditions that EV cells, modules, and packs may encounter. By subjecting these components to controlled environmental stresses, it allows manufacturers and researchers to evaluate their performance and durability. This is crucial for ensuring the safety and reliability of EVs, as any failure in the battery system could lead to reduced range, performance issues, or even safety hazards.
• Product Design Optimization and Quality Control
  • Through a series of tests on different EV component prototypes, the data obtained from the chamber can be used to optimize product designs. Engineers can analyze the behavior of various materials an
