Walk-in Battery Test Chamber

As a professional manufacturer of environmental testing equipment, we are committed to providing stable-performance, precision-controlled testing solutions.

The Sanwood Walk-in Battery Test Chamber is engineered for comprehensive environmental and performance validation of large-format battery packs, modules, and complete energy storage systems. Combining spacious testing volume with precise climatic control and integrated charge-discharge cycling, this solution enables realistic testing of battery behavior under controlled yet extreme operating and storage conditions.

• •Ample interior space accommodates entire battery packs, stacked modules, or multiple units under test.
• •Delivers stable temperature ranges, humidity control, and thermal cycling for real-world simulation.
• •Integrated Safety & Monitoring – Built-in thermal runaway gas detection, fire suppression interfaces, exhaust ventilation, and real-time voltage/temperature monitoring for high-risk testing scenarios.
• •Compatible with high-power battery cyclers, data acquisition systems, and BMS communication protocols for synchronized environmental and electrical testing.

When the battery is undergoing extreme testing or has internal short circuits, thermal runaway and other faults during actual use, it can effectively isolate the shock waves and flames generated by the explosion and prevent them from spreading to the external environment, thereby ensuring the safety of the laboratory or workplace.

• •Electric vehicle industry: used to test the performance, stability and safety of electric vehicle battery packs under various working conditions.
• •Energy storage system: evaluate the performance and reliability of battery packs in large-scale energy storage systems.
• •R&D institutions: suitable for the research and development of battery materials and battery management systems.

The walk-in battery  test chamber can perform a variety of tests such as charge and discharge cycle testing, fast charging testing, overcharge testing, short circuit testing, temperature shock testing, etc. Its common test standards are as follows:

• •UN 38.3: Regulation No. 38.3 in the United Nations Recommendations on the Transport of Dangerous Goods, mainly for the transportation test of lithium batteries.
• •IEC 62133: International Electrotechnical Commission (IEC) standard, covering the safety and performance testing of rechargeable batteries (such as lithium batteries).
• •UL 1973: Underwriters Laboratories (UL) specification, mainly for battery energy storage devices, covering safety and performance requirements.
• •SAE J2464: Standard of the American Society of Automotive Engineers, mainly for the testing of lithium batteries in electric vehicles. The walk-in battery test chamber also complies with testing standards such as EN 60079, IEC 62233,SAE J2464, SAE J2929,IEC 62133,IEC 60086-4, etc

The control system of the Sanwood test chamber adopts the world's leading software and hardware system to ensure that the test chamber operates under preset conditions, provide accurate and reliable experimental data, and help users achieve precise control and data collection of various experimental conditions.

• •Controller: It adopts the controller imported from South Korea Sanwon and the self-developed control system, which can be equipped with Siemens control system and equipped with RS232, RS485 and Ethernet communication ports.
• •Programmable control: It supports setting experimental programs, such as heating, cooling, constant temperature time, etc., and can execute multiple program settings, and supports advance reservation startup function.
• •Multiple languages are available: English, Korean, Russian, Chinese and Japanese.
• •Remote monitoring: Using network remote technology to achieve remote control, the test chamber can be monitored at any time, and the current data can be viewed through the user's PC and mobile phone, which improves the convenience of testing. The specific control system of the test chamber will vary depending on the model. Please read the "Sanwood Environmental Test Chamber Manual" carefully before use and comply with the safety operating procedures.

The refrigeration system of the test chamber is a complex and important system. The stability of the refrigeration system is crucial to the accuracy and reliability of the test results.

• •Sanwood Technology has developed a refrigerant hot gas defrosting technology, which effectively melts the frost on the evaporator by injecting high-temperature and high-pressure refrigerant steam into the heat exchanger in the test chamber. This not only ensures that the evaporator does not frost, but also greatly reduces the energy consumption of the equipment.
• •The refrigeration unit adopts an internationally renowned brand.which is more efficient and energy-saving, and reduces noise.
• •Optimize the layout of the refrigeration system, and adopt VRF (refrigerant flow control) technology based on the PID cold end output principle to achieve low-temperature energy-saving operation, which can reduce energy consumption by 30% under low-temperature conditions.
• •The refrigeration system adopts a modular design, with low failure rate, few welding points, high refrigeration efficiency, good reliability, simple maintenance, and low maintenance cost.
