The battery charge&discharge test chamber is a device specially designed for charging and discharging safety tests on batteries ( such as lithium-ion batteries).This type of test chamber can simulate the extreme charge and discharge conditions that the battery may encounter in actual use to evaluate

Advantages of Sanwood Test chamber

The battery charge&discharge test chamber has a battery charge and discharge cabinet or a charge and discharge device configured in the test chamber.

• Can evaluate the battery life of the battery in charge and discharge tests.
• The equipment manufacturing complies with UN38.3 , UL, IEC, SAE, GB/T testing standards.
• The equipment has balanced and stable heating and humidification performance.
• The test chamber complies with the best safety test for EUCAR hazard levels (0-7).
• Equipped with safety devices proven in battery explosion tests, it provides the best protection against this type of danger.
• Simulate various states of the battery in actual use to more accurately evaluate its performance.

Main Application of Battery Test Chamber

The explosion-proof test chamber for charging and discharging batteries is widely used in battery manufacturing, research and development, quality inspection and safety assessment, and is especially important in the safety verification of lithium-ion batteries used in electric vehicles, energy storage systems and consumer electronics. Its test uses are as follows:

• Charge and discharge operation: During the test, the battery explosion-proof test chamber can charge and discharge the battery, simulating various states of the battery in actual use, so as to more accurately evaluate its performance.
• Overcharge and over-discharge test: Battery explosion-proof test chambers are often used to conduct overcharge and over-discharge safety tests on batteries. Placing it in an explosion-proof chamber and connecting it to a charge and discharge tester can ensure the safety of the test process even if the battery fails under extreme charging or discharging conditions.
• Short-circuit protection performance: The battery explosion-proof test chamber simulates a battery short-circuit to test whether the battery’s short-circuit protection mechanism is effective and how the battery reacts after a short circuit.

The charge and discharge battery explosion-proof test chamber should be able to perform reliability tests on the battery, such as cycle life test, storage life test, etc. These tests can evaluate the reliability of the battery under different usage conditions to determine the service life and safety of the battery.

The Test Standards Of Battery test Chamber

charge and discharge battery explosion-proof test chamber should be able to perform reliability tests on the battery, such as cycle life test, storage life test, etc. These tests can evaluate the reliability of the battery under different usage conditions to determine the service life and safety of the battery.

• IEC 60086-4: Safety standard for lithium batteries, Part 4 of primary batteries, about the safety of lithium batteries , including altitude simulation test, thermal cycle test, external short circuit test and thermal abuse test.
• SAE J2464: Guidelines for safety and abuse testing of rechargeable energy storage systems for EVs and HEVs , including thermal stability testing and temperature cycling testing.
• IEC 62233: Electrical safety in the workplace - Explosion protected equipment.This standard specifies the requirements for explosion-protected equipment, including batteries, in hazardous areas.
• UL 913: Standard for Safety for Intrinsically Safe Apparatus and Associated Apparatus for Use in Class I, Division 1, Hazardous (Classified) Locations.

The three-layer battery explosion-proof test chamber also complies with testing standards such as EN 60079, IEC 62233,SAE J2929, UN/DOT 38.3,IEC 62133,IEC 62660-2, etc

Control System Of Battery Test Chambers

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.

Refrigeration System Of Battery Test Chamber

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.
