Testing Chambers Knowledge

The battery pack crush nail penetration testing machine plays a crucial role in battery safety performance testing. With the continuous development of battery technology and the expansion of battery application fields, especially in the fields of new energy vehicles, mobile devices, etc., the safety of batteries has become a focus of people's attention. The function of the battery pack extrusion needle punching test machine is mainly reflected in the following aspects: Evaluate battery safety performance The battery pack crush nail penetration testing machine evaluates the safety performance of batteries by simulating the compression and needle punching of battery packs under extreme conditions. This test can reveal the reaction of batteries when subjected to external forces or internal short circuits, such as whether thermal runaway, fire, or explosion occurs. Prevent potential security risks By conducting crush nail penetration tests on battery packs, potential safety risks can ...

  The temperature chamber   and   the temperature humidity chamber   are two important types of simulated enironmental chambers in envrionemntal chamber. These temperature humiditychambers is widely used in electronics, machinery, chemical, construction and other industries. It provides a reliable artificial environment for environmental adaptability research of various equipment, materials and components. High low temperature chamber  has been widely used in electronics industry and some industries with high precision requirements. However, as processes and technologies improve, the ability to test chamber is increasing. Many different testing requirements and testing indicators will be encountered during the testing process. For example, the current constant temperature humidity chamber is required to be tested under low temperature and low humidity conditions. The thermal shock chamber requires temperature changes above 30 °C per minute and so on. This brings...

  Simulated environmental testing is an activity carried out to use, transport or store products in an intended environment to maintain product functional reliability. The simulated environmental test is mainly used to analyze the degree of influence of environmental factors and its mechanism of action. Because the simulated environmental test is not subject to nature, it is not limited by time and place, saving manpower, material resources, and can be carried out all day. Therefore, simulated environmental tests are widely used around the world.  On the one hand, it shows its scientific nature, on the other hand, it also confirmed its value. Simulated environmental testing techniques are the result of long-term repeated practice by several generations of scientists. Simulated Environmental Test Classification Under normal circumstances, environmental tests are divided into two categories:  Climate environment test Mechanical environment test 1. Climate environmental test...

  Present Situation Since the mass production of lithium batteries, it has quickly led the trend in the battery field with its high energy ratio, long cycle life, and high electrode voltage. It has an absolute advantage in mobile phones, computers and other industries. And become one of the important research topics of the current new energy vehicles. In order to meet the market demand for high storage energy, enterprises have increased the specific energy research and development of individual batteries. Although it is possible to increase the waiting time of the mobile phone, it also makes the volumetric energy density of a single battery higher and higher. The safety of lithium batteries is becoming more and more prominent. The main constraint to the commercialization of high-capacity and lithium-ion batteries is safety. Constrained Problem However, in recent years, with the large-scale utilization of the market and the increase in the capacity of the battery itself, under the a...
