Battery Explosion-proof Test Chamber

The battery explosion-proof test chamber is a professional testing equipment, which is mainly used to evaluate the safety and reliability of batteries in various extreme environments.

• •A variety of safety devices can be selected according to test requirements.
• •The equipment manufacturing complies with UN38.3 , UL, IEC, SAE, GB/T testing standards.
• •The test chamber complies with the best safety test for EUCAR hazard levels (0-7).
• •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 battery explosion-proof test chamber is widely used in the battery manufacturing industry, new energy vehicle industry and related R&&D laboratories.

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.

• •Battery temperature cycling performance: The battery explosion-proof test chamber simulates a temperature cycling environment to test the adaptability and stability of the battery under conditions of rapid temperature changes.
• •Battery high and low temperature testing: The battery explosion-proof test chamber can simulate high and low temperature environments to test the battery's high and low temperature resistance under these conditions.
• •Other extreme environment tests: The battery explosion-proof test chamber can simulate extreme environmental conditions such as high voltage and low voltage to comprehensively evaluate the stability and reliability of the battery.

Among the various installation devices equipped in the battery explosion-proof test chamber, the fire extinguishing device is a very important one. It can configure different fire extinguishing devices according to the combustion conditions of the test product, and can also be configured with intelligent control, which can not only avoid fire, but also protect the test equipment from damage.

Battery explosion-proof test chamber should be able to perform reliability tests on batteries, such as cycle life tests, storage life tests, etc. These tests can evaluate the reliability of batteries under different usage conditions to determine the service life and safety of the batteries. There are testing standards for each aspect of the battery , such as:

• •UN/DOT 38.3: United Nations lithium battery testing requirements, which stipulates the safety testing standards for lithium batteries during transportation.
• •IEC 60086-4: Safety standard for lithium batteries, Part 4 of primary batteries, about the safety of lithium batteries. It includes altitude simulation test, thermal cycle test, external short circuit test and thermal abuse test, etc.
• •UL 913: Standard for Safety for Intrinsically Safe Apparatus and Associated Apparatus for Use in Class I, Division 1, Hazardous (Classified) Locations.This standard specifies the requirements for intrinsically safe apparatus, including batteries, for use in hazardous locations.
• •CSA C22.2 No. 157: Explosive atmospheres - Part 1: This standard provides requirements for equipment intended for use in explosive atmospheres, including batteries.

The three-layer battery explosion-proof test chamber also complies with testing standards such as EN 60079, IEC 62233,SAE J2464, SAE J2929,IEC 62133,IEC 60086-4, etc

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

• •Controller: The TEMI 1500 controller imported from Sanwontech in South Korea and the self-developed Siemens control system are used, equipped with RS232, RS485, and Ethernet communication ports.
• •Programmable control: supports setting experimental programs, such as heating, cooling, holding time, etc., and executing multiple program settings.Support advance reservation for power on 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 emails can be sent to users' PCs and phones, enhancing convenience.

The specific control system of the test chamber may vary depending on the model, so it is necessary to carefully read the Sanwood Environmental Test Chamber Manual and follow safety operating procedures before use.

The refrigeration system of the test chamber is a complex and important system, and the quality of the refrigeration system is crucial for the accuracy and reliability of the test results.

• •Sanwood has developed hot air refrigerant defrosting technology, which effectively melts the frost on the evaporator by injecting high-temperature and high-pressure refrigerant vapor into the heat exchanger inside 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 international famous brands and cooperates with Japan's Eginomiya and the US Sporan to develop EPV series and XUP series quick opening solenoid valves for energy-saving systems, with an all-weather service life of over 15 years. And began to develop the new Danfoss AKV series throttling electronic expansion valve system, which is more efficient and energy-saving.
• •Optimizing the layout of the refrigeration system adopts VRF (refrigerant flow control) technology based on 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 modular design, achieving low failure rate,less welding joints, high refrigeration efficiency, good reliability, simple maintenance, and low repair costs.
