The author analyses the necessity of 3 c lithium battery test

Source: 2020 - 03 - 29 and clicks: 3 c 3 c lithium battery in the application of the lithium battery application field are mainly concentrated in the electronic market, mobile phones, laptops, tablets, smart products such as demand for 3 c lithium battery is concentrated and widely. In addition, the 3 c lithium-ion batteries in electric cars and industrial/also occupies an important proportion of energy storage applications. From this perspective, 3 c lithium battery in the field of communications and transportation has penetrated into people's life. With the development of intelligence technology, wearable intelligent equipment, unmanned aerial vehicle (uav) new intelligent products has been applied gradually. 3 c lithium batteries, therefore, relatively wide prospect of market. 2, 3 c lithium batteries since 2012, the importance of smart mobile phones began to replace traditional function in the Chinese market. Today, the appearance of the smart phone is more and more fashionable and beautiful, the body is becoming more and more frivolous, function of rapid expansion. When people choose, they will pay more attention to the hardware of the mobile phone function. With the increase of mobile phone software and the increase of energy consumption, durability of mobile power supply will be one of the most important factor when the public to buy mobile phones. With the rise of Chinese enterprises in the smartphone market, huawei, millet, the influence of the oppo, zte, lenovo mobile phone brands such as more and more profound, in the production of smartphones, on a piece of hardware function also can have higher requirements. It usually for China's lithium battery store is a good thing. Iii. 3 c lithium battery checking mobile phones, portable power supply and the necessity of tablets factory have to pass strict inspection, especially a battery-powered device. In the lithium battery tests, there will be a series of tests, including appearance, basic chemical testing, functional testing of lithium battery. At first, this paper illustrates the necessity of 3 c lithium battery testing capabilities. Test 3 c lithium battery life is very important. Lithium battery of number means it can charge and discharge cycles. According to the battery working environment, under different temperature cycle life can achieve it; While it is presented. according to and presented. according to standard is to pass the measurement standard. 3 c lithium battery safety test more and more important. When we see in the news of mobile phone battery explosion, we must be concerned about the security of mobile phone function, so the battery safety test is necessary. Test need professional module test equipment for the stability of the lithium battery and impedance test them one by one. Four, pogo pins in 3 c lithium battery detection probe the problems existing in the module for 3 c lithium battery detection, using the probe module on the market at present pogo pin is also imperfect. Because of the limitation of the pogo pin detector module 3 c lithium battery detection has a lot of problems. The appearance of sensor module by a needle, syringe and needle tail three parts. In the process of conduction, current can be in different parts of the attenuation, just under the influence of different contact area, rated current is only 1 a. Pogo pin detector module is composed of many parts, contact point, more prone to contact is not stable, low impedance consistency problem. When the probe in testing the mother can only come into contact with the connector end vertex maximum azimuth, point to point contact way cause wear and tear. When after reaching a certain number of applications, and broken card needle will appear, lead to measurement error. Because the master BTB connector pogo almost impossible, so it's easy to breakage, stability is poor. Most of them choose a light touch on the solution to a temporary deal with it. In addition, the life of the pogo pin detector module has passed about 5 w times detection, mother block test yield is only 80%. In addition, the pogo pin detector modules due to the processing difficulty is big, high production cost, long construction period, no longer has the advantage in the market, new shrapnel microporous modules are replacing its location. Five, the blade pin high current shrapnel micro needle module in the 3 c the advantages of lithium battery testing large current shrapnel micro blade needle module is specifically designed to test the 3 c lithium battery and micro needle module of BTB connector. Micro blade needle module, good solved the difficulties encountered in the detection of pogo pin detector module.
