• Environmental Testing of Rechargeable Battery

  Feb 21, 2025

  Rechargeable battery, which can be re-active by charging after be used. They are widely used in the fields of environmentally friendly vehicles, power storage, and Dynamic field. Environmental testing of rechargeable battery is an important means of evaluating their performance under different environmental conditions. Ⅰ.  Testing Purpose The environmental testing of rechargeable battery aims to simulate various conditions that may be encountered in actual usage environments to evaluate the reliability and performance of the battery. Through testing, it is possible to understand the conditions of working battery under different temperature, humidity, vibration, impact and other conditions, providing scientific basis for the research and development, production and use of battery. Ⅱ.  Testing content A. Temperature testing a. High temperature test: Rich a high temperature environment to observe its temperature stability and the risk of thermal runaway. b. Low temperature testing: Testing the discharge performance, capacity degradation, and low-temperature starting ability of the battery under low temperature conditions. c. Temperature cycling test: Simulate the temperature changes that the battery may experience in actual use, evaluate its thermal durability and cycle life. B. Humidity test: Evaluate the battery’s performance, sealing, and corrosion resistance in a humid environments. C. Vibration testing: Through simulate the battery in the vibration environment that may encounter during transportation, installation, and use, evaluate its structural integrity, electrical connection reliability, and performance stability. D. Impact testing: Through simulating the battery in unexpected situations such as drops and collisions, and evaluate their impact resistance. E. External short circuit test: Test the performance of the battery under external short circuit conditions, including risks of thermal runaway and explosion and so on. Ⅲ. Test standards and specifications The environmental testing of rechargeable battery should follow relevant testing standards and specifications to ensure the accuracy and comparability of test results. Common testing standards include: IEC 62133/ IEC 61960、UN 38.3、UL 1642/UL 2580、GB/T 31467、JIS C 8714 Ⅳ. Test equipment Environmental testing on rechargeable battery requires the professional testing equipment and methods. Common testing equipment includes： High and low temperature test chamber: Used to simulate different temperature environments. Humidity test chamber: used to evaluate the performance of battery in humid environments. Vibration test bench: Simulate vibration environment to evaluate the structural integrity and performance stability of battery. Impact testing machine: used to simulate impacts in unexpected situations such as drops and collisions. Ⅴ. Test results and evaluation After completing the test, it is necessary to analyze and evaluate the test results. Based on test data and standard requirements, determine whether the performance of the battery meets the requirements under different environmental conditions. For undesirable battery, further analysis and corresponding improvement measures should be taken. In summary, environmental testing of rechargeable battery is an important means to ensure their stable and reliable performance in practical use. Professional testing instruments can provide more professional, safe, scientific and effective experimental results for rechargeable battery testing, greatly reducing the cost of testing and bringing convenience to companies.

• Introduction to the Solar Simulation Radiation Test Chamber

  Oct 16, 2024

  Introduction to the Solar Simulation Radiation Test Chamber The solar simulation irradiation test chamber, also known as the "solar radiation protection test device", is divided into three types according to the test standards and methods: air-cooled xenon lamp (LP/SN-500), water-cooled xenon lamp (LP/SN-500), and desktop xenon lamp (TXE). The difference lies in the temperature, humidity, accuracy, time, etc. of the test. It is an indispensable testing instrument in the aging test chamber series. The test chamber uses an artificial light source combined with a G7 OUTDOOR filter to adjust the system light source to meet the requirements of IEC61646 for solar simulators by simulating the radiation in natural sunlight. The above system light source is used to conduct the IEC61646 photoaging test on the solar cell module, and the temperature on the back of the module needs to be constantly controlled between 50 ± 10oC during the test. Can automatically monitor temperature; Configure a radiometer to control the irradiance of light, ensuring it remains stable at a specified level, while also controlling the testing time. During the ultraviolet light cycle period in the solar simulation irradiation test chamber, photochemical reactions are usually not sensitive to temperature. But the rate of any subsequent reaction depends on the temperature. The rate of these reactions accelerates with increasing temperature. Therefore, controlling the temperature during UV exposure is crucial. In addition, it is necessary to ensure that the temperature of the accelerated aging test is consistent with the highest temperature at which the material is directly exposed to sunlight. In the solar simulation irradiation test chamber, the UV exposure temperature can be set at any temperature between 50 ℃ and 80 ℃ based on the illuminance and ambient temperature. The UV exposure temperature is adjusted by a sensitive temperature controller and blower system to achieve excellent uniformity in the temperature of this test chamber.
