With the rapid development of new energy vehicles, energy storage systems, and aerospace fields, performance verification of power batteries under different environmental conditions has become particularly important. Especially in high-altitude, mountainous, or aviation application scenarios, low air pressure has a direct impact on the safety, reliability, and functionality of batteries.
To meet the special testing requirements of battery modules and battery packs, walk-in high-altitude simulation test chamber has been specially developed for battery testing. It can simulate temperature, pressure, and humidity conditions at different altitudes and meets the requirements of standards such as GB/T 31467, UN38.3, IEC 62133, UL 2580, etc.
This device is designed specifically for large-sized battery packs or multiple battery modules, integrating large space, high load, precise air pressure control, and temperature and humidity linkage regulation, providing a professional and reliable environmental simulation platform for battery research and verification.
1 Main functions and features
- Large testing space
The internal effective volume reaches 18 cubic meters, suitable for conducting comprehensive environmental tests on altitude, temperature, and humidity for the entire battery system or multiple large modules simultaneously.
- High precision air pressure control
It can simulate high-altitude environments ranging from 0 meters (atmospheric pressure) to 5000 meters, and even up to 10000 meters (as low as 10.9 kPa atmospheric pressure), with precise pressure regulation and small fluctuations, meeting various standard testing requirements.
- Temperature and humidity linkage function
The temperature range covers -40 ℃ to+100 ℃, and the humidity range is 20% RH to 95% RH. It can achieve stable temperature and humidity environment control under different pressure conditions and simulate complex climate conditions in high-altitude areas.
- Security protection system
Based on the characteristics of battery testing, multiple safety mechanisms such as explosion-proof pressure relief device, smoke alarm, hydrogen detection system, high temperature and over temperature protection, and door lock linkage protection are configured.
- Intelligent control system
Equipped with high-performance PLC and color touch screen display, supporting multi-stage program settings, real-time monitoring, remote control, and data recording. The testing process is traceable and meets laboratory management standards.
- Reliable airtightness and pressure bearing structure
Adopting thick stainless steel inner liner and high-strength box structure to ensure equipment sealing and structural safety under long-term low-pressure conditions.
- Efficient and energy-saving design
By using imported compressor units and optimized air duct systems, the advantages of low energy consumption, fast temperature control, and stable air pressure can still be maintained in large volume environments.
