3 c lithium battery quality test

Source: 2020 - 03 - 29 then click traffic: 3 c lithium battery quality inspection, promptly has very big effect to the micro needle module! Must see, 3 c quality detection, lithium-ion batteries shrapnel microporous module has much effect! 3 c is refers to the mobile phone batteries, laptop battery, mobile power consumption, such as battery. The use of the 3 c product characteristics determine the performance of the 3 c lithium batteries and quality requirements, so it is necessary for the 3 c lithium batteries for testing. 3 c lithium battery test difficulty lies in the current is too large, the traditional sensor module can not meet the required current, so you don't normally use. Rev of shrapnel micro needle module can take 3 c lithium battery by current transfer 50 largest when a current, have better connection function, improves the 3 c lithium battery test finished product yield. 3 c products are widely used in lightweight, portable, high-performance, long life and other fields, and puts forward new requirements to the 3 c lithium battery, high specific capacity, high security, small volume, the battery and battery encapsulation also put forward higher requirements. How to detect the quality of the 3 c lithium battery, the need to use the following methods: 1. View 3 c lithium battery appearance, investigate whether lithium battery appearance damage or deformation, etc, to see the fullness of the 3 c lithium battery and precision work; 2. Check the 3 c hardness of lithium-ion batteries. With the hand gently knead a lithium battery. Hardness is moderate. 3. Check the weight of the 3 c lithium batteries, remove the lithium battery packaging, the weight of the lithium battery, if you have the feeling of weight, 3 c lithium battery is the high quality batteries; 4. Test lithium battery internal resistance and 3 c maximum current, select 20 series of multimeter, short connecting two electrodes of lithium battery, at present in 10 or higher, you can stay for a period of time, relatively stable, small internal resistance, large discharge current display 3 c lithium battery's quality is very good. 5. 3 c lithium battery charged operation, continuous discharge for 10 minutes, no fever, lithium batteries poles that 3 c lithium battery protection board quality is relatively high, the battery quality is better. In 3 c lithium battery test, the service life of shrapnel microporous module is very high, an average of more than 20 w, if the operation, the environment, good maintenance, in the case of service life can reach 50 w. In the field of small pitch, shrapnel microporous modules, strong adaptability, can be at zero value. 15mm ~ 0. Between 4 mm. Promptly after plated, needle and card pin is not easy to fracture in the process of test, for a long time is not easy to break. Compaction shrapnel micro needle module is using laser equipment through special process. Integrated design made the current conduction in the same data volume, constant resistance, almost no current attenuation, very stable. In the improvement of 3 c lithium battery test power supply at the same time, without damage of lithium battery, joint test yield is as high as 99. 8%! In the 3 c lithium battery test plays an important role.
