Environmental Simulation Test is conducted to verify the functional reliability of products during use, transportation and storage. It is to expose the product to natural or artificial environmental conditions to undergo its action, so as to evaluate the performance of the product under the environmental conditions of actual use, transportation and storage, and analyze and …

The temperature test chamber is generally composed of working room, adjusting equipment, auxiliary equipment and control system. The regulating system includes heater, evaporator and air supply device, and auxiliary equipment main room refrigeration unit. The control system includes temperature controller, program setter, safety alarm device and so on.   The heater is realized by electric …

As a type of reliability test, environmental test has developed into a method to predict how the product environment affects the performance and function of the product. In other words, environmental tests are used to assess the degree of environmental impact on products before they are put into the market. When the function of the …

Environmental chamber manufacturer DGBELL introduces a great chamber which combines temperature, humidity and vibration into one equipment. This Temperature Humidity Vibration Combined Test Chamber is mainly to simulate the adaptability, safety and integrity of product in the process of transportation and actual use in the change of temperature, humidity, vibration and also other complex environments. …

The cycle life of lithium batteries has always been one of the most important parameters for electric vehicle buyers. How does a lithium battery get old? Aging always appears together with failure, but to be precise, aging and failure are two concepts. Aging, which refers to the deterioration of power battery performance parameters over time, …

The activation stage of lithium battery pack includes precharge, formation, aging, constant capacity and so on. There are two main factors influencing the performance of lithium battery pack, namely aging temperature and aging time. What’s more, it is important that the battery tested in the aging test chamber is in a sealed state. If it …

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 …

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, …

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 …
