Double-layer Battery Test Chamber

The double-layer battery explosion-proof test chamber adopts a superimposed double-layer design structure and has two independent control systems,compared with the general battery explosion-proof test chamber.

• •Better use of laboratory space and more space cost saving.
• •Can cooperate with unmanned automation design to save labor costs.
• •The equipment has balanced and stable heating and humidification performance.
• •Equipment manufacturing complies with UL, IEC, SAE, and GB/T testing standards.
• •The test chamber complies with the best safety test for EUCAR hazard levels (0-7).

The double-layer battery test chamber is mainly used to evaluate the safety performance of batteries in various extreme environments , and is also widely used in the battery manufacturing industry and related R&D laboratories .

Double-layer battery explosion-proof test chambers are mainly used to perform safety tests on batteries (especially lithium-ion batteries) to evaluate their performance and safety under extreme conditions. These test chambers can simulate various situations that may cause battery explosion or fire, including overcharging, short circuit, high temperature, high voltage, etc. as follows:

• •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.

The double-layer battery explosion-proof test chamber can effectively evaluate the safety of batteries under extreme conditions to determine whether they meet relevant safety standards and application requirements.

double-layer 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 62660-2: Reliability and abuse testing of lithium-ion batteries for electric vehicles. Covers capacity discharge test, high temperature endurance test, temperature cycle test, etc.
• •SAE J2464: Guidelines for safety and abuse testing of rechargeable energy storage systems for EV and HEV. Including thermal stability testing and temperature cycling testing, etc.
• •IEC 62233: Electrical safety in the workplace - Explosion protected equipment.This standard specifies the requirements for explosion-protected equipment, including batteries, in hazardous areas.

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.
