Walk-In Battery Pack Climatic Test Chamber
Walk-In Battery Pack Climatic Test Chamber is designed for testing large battery assemblies commonly found in electric vehicles, energy storage systems, and similar applications. It creates a controlled environment for evaluating battery performance under various conditions, including high and low temperatures, charge/discharge cycles, overcharging, and short circuits.
Application Fields of the Walk-In Battery Test Chamber
The explosion-proof walk-in battery test chamber features a robust steel construction and superior containment capabilities. During extreme testing or battery failures—such as internal short circuits or thermal runaway—it effectively contains shockwaves and flames, preventing them from reaching the surrounding environment and ensuring safety in laboratories or workspaces.
Key Application Areas:
- Electric Vehicle Industry: Used to assess the performance, stability, and safety of battery packs under various operating conditions.
- Energy Storage Systems: Evaluates the reliability and functionality of battery packs in large-scale energy storage applications.
- Research & Development: Ideal for the development and testing of battery materials and battery management systems.
The chamber is equipped with a high-efficiency temperature control system, enabling both high- and low-temperature testing to ensure consistent battery performance in diverse environmental conditions.

- Programmable Control: Allows users to create and run complex testing sequences, including heating, cooling, and constant temperature cycles. Multiple programs can be scheduled with an advanced start-time reservation feature.
- Multilingual Support: Interface options include English, and other languages.
- Remote Monitoring: Equipped with EZNET technology for real-time remote access. Users can monitor chamber status and test data from a PC or mobile device, enhancing convenience and control.
Note: Control system specifications may vary by model. Always refer to the "Environmental Test Chamber Manual" and follow all safety guidelines before operation.
Refrigeration System of the Climatic Test Chamber
The refrigeration system plays a critical role in the performance of the test chamber. Its stability directly impacts the accuracy and consistency of test results.
- Hot Gas Defrosting Technology: Qualitest Technology has developed an advanced hot gas defrosting method that injects high-temperature, high-pressure refrigerant vapor into the chamber’s heat exchanger. This process effectively prevents frost buildup on the evaporator and significantly reduces overall energy consumption.
- High-Quality Refrigeration Components: The system features components from leading global brands. Qualitest has integrated EPV and XUP series quick-opening solenoid valves designed for long-term reliability—exceeding 15 years of continuous operation. Additionally, a next-generation Danfoss AKV electronic expansion valve system is under development, offering greater efficiency, reduced noise, and improved energy savings.
- Energy-Efficient Operation: The system layout is optimized using VRF (Variable Refrigerant Flow) technology based on PID cold-end output control. This design enables energy-efficient low-temperature operation, reducing energy consumption by up to 30%.
- Modular Design: The refrigeration system uses a modular approach, which results in fewer welding points, lower failure rates, higher cooling efficiency, and simplified maintenance. This contributes to overall reliability and lower maintenance costs.
