The 3 c certification process and test solution lithium-ion batteries

Source: 2020 - 03 - 29 then hits: 3 c lithium battery certification process and test solution 3 c lithium battery including the scope of application of portable electronic products and mobile communication products. In short, used in mobile phones, tablets, laptops, wearable equipment products such as battery generally referred to as the 3 c lithium battery. 3 c lithium battery as a kind of energy storage component, its safety and importance cannot be ignored. In order to ensure the security of electronic products of lithium-ion batteries, improve the production management ability of enterprises, to promote and standardize the development of battery industry, 3 c lithium battery needs 3 c certification and testing. This article mainly expounds the 3 c certification process of lithium battery and test scheme, and used to connect to test, and the conduction of the effect of the large current shrapnel micro needle module. 3 c certification process 3 c lithium-ion batteries lithium battery certification is divided into four steps: first, determine the using range of lithium-ion batteries; 2. Confirm the 3 c lithium battery test content; 3. 3 c lithium battery samples will be sent to battery testing laboratory tests; 4, check the 3 c lithium battery factory, determined to conform to the specifications of qualified, the lithium battery 3 c authentication certificate. 3 c certification testing lithium-ion batteries 3 c certification test lithium-ion batteries include: 1. General safety requirements 2 safety requirements. Battery maintenance circuit security system maintenance circuit safety requirements ( 4) General requirements 2. Safety test battery safety experiment ( 2) Battery environment security experiment ( 3) The battery safety experiment ( 4) Battery environment security 3 c lithium battery tests deal 3 c lithium batteries through 3 c certification, battery manufacturers can be put into production. To complete the 3 c lithium battery also need for performance and safety testing. How to ensure that test safely and effectively is the most important of the demand for processing. Large current shrapnel micro needle module for 3 c lithium battery test provides a treatment scheme. Large current shrapnel micro needle module is connected with the conduction transfer preface, can effectively guarantee the 3 c connect the continuity of the lithium battery test process. It can be achieved by large current transmission, and in the small pitch class has a strong habit, high service life. Large current shrapnel micro needle module rated current up to 50 a, current transmission in 1 - 50 a scope is very stable. Reason is that the current flows in the same data volume, the resistance is constant, not happen current attenuation, so it has better connection function, make the 3 c lithium battery test smoothly. In the small pitch class, large current shrapnel micro needle module, the minimum pitch value can reach 0. 15 mm, breakthrough the limitation of the traditional sensor module. At zero. 15mm ~ 0. Between 4 mm, with strong habitability, its performance and service life is much higher than the probe module, stable and reliable connection. Large current shrapnel microcrystalline module of uniform service life more than 20 w, under the condition of good operation, environment and maintenance can be up to 50 w. In the 3 c lithium battery test maintain long-term stability. Shrapnel head of self-cleaning function, make test without impurities, yield of 99. 8%. For 3 c lithium battery manufacturers, the characteristics of large current wafer micro module well solved the problem of the 3 c lithium battery test, provided the guarantee of stability for test. Can assist the 3 c the orderly production of lithium batteries, both in performance and price is very high.
