  This passage summarizes the mechanism of thermal runaway and preventive measures, which have been applied in the design and manufacturing of all battery systems. However, in practice, different material systems have different chemical characteristics, so the thermal runaway mechanism of the battery core is different. Different system designs will also lead to different system-level risks and different solutions. Among them, the explosion is the power battery system is more common harm performance, caused by the impact, is more serious, not only will cause property loss and environmental damage, or even cause personal injury or life danger. Possible causes of combustion or explosion of a power battery system are: The exothermic side reaction of the power battery (cell) leads to thermal runaway and ignites the electrolyte and other combustible substances; 1、The local connection resistance of the high voltage circuit of the power battery system is too large, and when a large current...

  About salt spray test The salt spray corrosion test can evaluate the ability of salt spray corrosion to materials and their protective layers, and the comparison of process quality of similar protective layers, and also the ability of some products to resist salt spray corrosion. It is mainly used for the corrosion test of parts, electronic components, metal materials and industrial products. Salt fog test is mainly to test the influence of salt fog environment on the product in atmospheric corrosion environment, and provide data reference for product optimization. The environmental effects of salt fog can be divided into three categories: corrosion effect, electrical effect and physical effect. Corrosion effect: electrochemical reaction corrosion, accelerated stress corrosion, acid-base corrosion Electrical effects: salt deposits damage electrical equipment, produce conductive coatings, insulation materials and metal corrosion Physical effect: corrosive substances affect the ope...

  6 Facts About Vibration Testing Systems Vibration problem exists widely in the popular life and production, buildings, machines or the outside world will produce vibration under the incentive. And mechanical vibration often damages the normal work of machinery, and even reduces the service life of machinery and causes irreversible damage to the machine. Most of the mechanical vibration is harmful.  Therefore, the study of vibration is not only conducive to improving the living environment and living standards, but also helpful to improve the service life of mechanical equipment. Mechanical vibration testing technology plays a very important role in industrial production, manufacturing efficient mechanical vibration testing system has become an important content of testing technology. What is  mechanical vibration ? Mechanical vibration refers to the process in which the displacement of an observation point on the mechanical equipment or structure changes with time aroun...

  Nowadays, battery is widely used in various fields as a storage method of renewable energy. In addition, the research on battery has been deepening, which makes the scope of its application gradually expanded from ordinary electronic equipment, electrical machinery, etc. to the power battery of electric vehicles and important components of aerospace equipment and so on. The widespread application of batteries is not only the credit of battery safety detection, but also the batteries without various safety technical standards can not be applied to the energy power system of general electronic and mechanical equipment. The batteries in scientific research direction, let alone, safety and stability are placed first. Because the battery test covers a wide range, this paper takes the stability of the battery in the high and low pressure environment as the foothold. Through the introduction and comparison of three products of our company, the relevant knowledge of the high altitude low...
