Vehicle Environmental Chamber

A comprehensive environmental test chamber specifically developed for electric vehicles. It performs temperature-humidity cycling, thermal shock, and performance testing on battery cells, battery modules, and BMS, meeting reliability verification requirements from component to vehicle level.

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.

• •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 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.

• •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.

• •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.

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 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.
• •The refrigeration unit adopts an internationally renowned brand.
• •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.
