We sincerely invite our customers and those who are taking interest in Battery Testing Technology to visit us at the exhibition. We are glad to share our latest battery testing technology with …
UN38.3 Standard Testing Items & Procedures The UN38.3 standard includes the following 8 detection items: T1 low pressure, T2 temperature cycle, T3 vibration, T4 shock, T5 external short circuit, T6 heavy object impact (lithium battery core), T7 overcharge (lithium battery or lithium battery ) T8 forced discharge (lithium battery cells). For lithium batteries or lithium …
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, …
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 …
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 …
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, …
With the widespread use of lithium-ion batteries in people’s daily lives. The safety performance of lithium-ion batteries is getting more and more attention. For example, the battery explosion of digital camera manufacturer Nikon in 2005, the explosion of Nokia mobile phone battery in 2006 and the battery explosion of Apple’s mobile phone. These accidents have …
The thermal shock chamber is capable of simulating transient changes before high temperatures and low temperatures. It is generally used to determine if physical damage or performance degradation occurs when the equipment is subjected to drastic changes in ambient temperature. It is an essential test equipment for aviation, automotive, home appliances and scientific research. To …
Battery testing is an important part of ensuring battery safety and reliability. Because the battery itself has certain risks (such as short circuit, leakage, leakage corrosion, etc.), the detection process also hides various safety risks. In the inspection process, large-scale mechanical auxiliary equipment, high-current charging and discharging systems, and simulation experiments of extreme environmental conditions …
