Testing Chambers Knowledge

  Foreword China is the world’s largest producer of primary batteries and the second largest producer and exporter of lithium-ion batteries. Battery products are high-risk products. In all aspects of its production, storage, transportation, testing and use, there may be safety accidents such as ignition and explosion. In recent years, China’s battery industry has developed rapidly, and battery product quality and safety have received widespread attention. Battery testing laboratories are also undergoing large-scale development. Due to the particularity of battery products, many testing items, such as thermal shock, heavy object shock, vibration, short circuit, overcharge and over-discharge, and forced reverse charging, are prone to explosion or even fire during the test. For this reason, while paying attention to the quality and safety of battery products and improving the ability of battery testing technology, it is also necessary to pay attention to the safety protection measures...

  With the development of science and technology, the requirements for the reliability of electronic components are getting higher and higher. Especially in aviation, aerospace and other applications. In general, in order to meet the reliability requirements of the project, a series of environmental tests are performed to verify the reliability of the component during the period from production to delivery. Among these environmental tests, the most important and effective test is the temperature cycling test.  According to the IES report from the United States, among various commonly used environmental screening stresses, the screening cycling temperature benefit is the highest, reaching 77%.  Therefore, the effective temperature cycling test is of great significance to improve the reliability of electronic components. Mechanism of Temperature Cycling Test Principle of Temperature Cycling Test The temperature cycling test mainly USES the difference of thermal expansion co...

  Lithium-ion batteries have attracted great interest because of their high capacity, high operating voltage, safety and stability, and no memory effect. And caused a worldwide climax of research. Lithium-ion batteries have thus rapidly developed into industrial applications and are widely used in portable appliances such as mobile phones, video cameras, and notebook computers.  This article briefly introduces the development trend of lithium-ion batteries and the safety problem. The Development Trend of Lithium-ion Batteries Today, mobile communication terminals such as mobile phones and tablet computers have become the most popular mass consumer electronic products. The battery is the only large-capacity energy storage component in the mobile communication terminal, which provides energy protection for the functions of the terminal. At the same time, the communication network is becoming more and more mature, and mobile communication terminals will become the focus of the en...

  Simulated Environmental test chamber mainly simulates a series of natural conditions such as high temperature, low temperature, moist heat, infrared radiation and low pressure, dust and mold. And the environmental test chamber has high requirements for analog accuracy. With the development of the industry, more and more customers need to implement the above environmental simulation, and put forward explosion-proof requirements for the equipment. Thereby adapting to a wider range of test samples. The Explosion- proof Structure of High Low Temperature Humidity Test Chamber 1. Chamber Reinforcement The outside of the chamber is strengthened with 80MM steel trough. The test chamber will be subjected to a huge impact when the explosion occurs. If the test chamber of the cabinet is not thick enough, it may even be deformed, damaged, spread of fire, and hard objects may cause accidental injury. Therefore, the reinforcement of the cabinet is very important. 2. Security Door In addition t...
