• •Can cooperate with unmanned automation design to save labor costs.
• •The test equipment is equipped with a high-precision intelligent temperature regulator. The temperature and humidity are displayed on a touch screen. Temperature and humidity recording is optional.

The walk-in battery pack test chamber allows operators to safely enter the test chamber for sample installation, maintenance and monitoring. This space design is suitable for testing large battery packs.

The battery explosion-proof test chamber is known for its sturdy steel structure and excellent explosion-proof performance. 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 pack test chamber is equipped with an efficient temperature control system, which can realize high and low temperature testing to ensure the stable performance of the battery pack under various environmental conditions.

The walk-in battery pack 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 pack 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 optional: English, Korean, Russian, Chinese and Japanese.
• •Remote monitoring: Using SAMWON-EZNET 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. In cooperation with Japan's Saginomiya and the United States' Sporlan, the EPV series and XUP series energy-saving system quick-opening solenoid valves have been developed, with an all-weather service life of more than 15 years. And began to develop a new Danfoss AKV series throttling electronic expansion valve system, 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.
