Vehicle Environmental Chamber

The vehicle environmental chamber is a special equipment used to test and verify the performance of the vehicle under different environmental conditions.so as to evaluate the durability, reliability and performance of the vehicle under severe weather, extreme temperatures and other external environmental conditions.

• •Suitable for battery module and vehicle battery pack testing.
• •The vehicle environmental test room is mainly composed of a test cabin, temperature and humidity control system, lighting simulation system, rain system, ventilation system, power system and other parts.
• •Full spectrum environmental simulation test to detect vehicle aging performance.
• •Simulated automobile exhaust emission environment test.
• •The box size can be customized according to test requirements.
• •The test chamber door has a protective device that can be opened from the inside to prevent people from being locked out.

The vehicle environmental chamber plays an important role in the process of automobile research and development and production. It can also be used in metrology, aerospace and defense industries . As far as automobiles are concerned, it is mainly used in the following aspects:

• •Battery testing: used to evaluate the performance of the vehicle under different climatic conditions, including the impact of high temperature, high humidity, low temperature and other environmental conditions on the charging and discharging, output power and other performance of the vehicle battery.
• •Electronic component testing: Conduct temperature and humidity tests on electronic components, sensors, control modules, etc. in the vehicle to evaluate their performance and stability.
• •Material testing: Evaluate the aging of body materials, interior materials, etc. under different temperature and humidity environments to ensure UV resistance, high temperature resistance, corrosion resistance and other properties.
• •Emission test: simulates automobile exhaust emission environment test to detect whether the automobile exhaust emission meets the standards, such as China , EU, Japan, EPA, CARB and other standards, and improves the automobile performance based on these standards.

The testing standards for vehicle environmental chambers are usually based on international and national standards, as well as technical specifications of the automotive industry. These standards are designed to ensure the performance, safety and reliability of the vehicle under various extreme environmental conditions. The following are some common vehicle environmental chamber testing standards:

• •ISO 16750: This series of standards deals with the testing of automotive electronic equipment under different environmental conditions, covering requirements in terms of temperature, humidity, vibration, etc.
• •ISO 9141: Standard for automotive electronic communications, including how the vehicle behaves under specific environmental conditions.
• •SAE J1211: Evaluates the performance of electric vehicles under different thermal conditions, which is also of reference value for the testing of vehicle environmental chambers.
• •FMVSS, EURO NCAP: Although these standards are mainly aimed at collision tests, they also often involve safety considerations of the entire vehicle under environmental conditions such as high temperature and high humidity.

These standards provide guidance for testing the vehicle climate chamber to ensure that the vehicle can meet the market's safety and performance requirements within its design life.

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.
