3C Lithium-ion battery certification process and test solutions

3C lithium battery certification process and test solutions 3C lithium battery use scope includes portable electronic products and mobile communication products. In short, the batteries used in mobile phones, tablet computers, notebook computers, wearable devices and other products are collectively referred to as 3C lithium batteries. As a kind of energy storage element, 3C lithium battery's safety and importance cannot be ignored. In order to ensure the safety of lithium batteries for electronic products, improve the company's processing and management capabilities, and promote and standardize the development of the battery industry, 3C lithium batteries require 3C certification and testing. This article mainly describes the certification process and test processing methods of 3C lithium batteries, as well as the effect of the high-current shrapnel micro-needle module used for connection testing and conduction. 3C lithium battery certification process 3C lithium battery certification is divided into four steps: first, determine the scope of use of the lithium battery; 2. confirm the test content of the 3C lithium battery; 3. send the 3C lithium battery sample to the battery testing laboratory for testing; 4. check The 3C lithium battery factory, after confirming that it meets the qualified specifications, obtains the 3C certification of lithium battery. 3C lithium battery certification testing content 3C lithium battery certification testing includes: 1. Safety requirements General safety requirements 2. Battery maintenance circuit safety requirements System maintenance circuit safety requirements (4) General requirements 2. Safety test Battery safety experiment (2) Battery environment Safety experiment (3) Battery safety experiment (4) Battery pack environmental safety experiment 3C Lithium battery test and treatment method After 3C lithium battery has passed the 3C certification, the battery manufacturer can put it into processing. The completed 3C lithium battery will also undergo performance and safety tests. How to ensure that the test is carried out safely and effectively is the most important issue for demand processing. The high-current shrapnel microneedle module provides a processing method for 3C lithium battery testing. The high-current shrapnel micro-needle module is the transmission preamble of connection and conduction, which can effectively ensure the continuity of the connection during the 3C lithium battery test process. It can transmit large currents, and has a strong habit in small pitches, and has a long service life. The rated current of the high-current shrapnel microneedle module can reach 50A, and the current transmission is very stable in the range of 1-50a. The reason is that the current flows in the same data body, the resistance is constant, and there is no current attenuation, so it has a better connection function, so that the 3C lithium battery test can proceed smoothly. In the small pitch category, the minimum pitch value of the high-current shrapnel microneedle module can reach 0.15mm, breaking through the limitation of the traditional probe module. Between 0.15mm~0.4mm, it has strong habitability, its expressive power and service life are much higher than that of the probe module, and the connection is stable and reliable. The average service life of the high-current shrapnel microcrystalline module exceeds 20w times, and can reach 50w times under good operation, environmental and maintenance conditions. Maintain long-term stability in the 3C lithium battery test. The self-cleaning function of the shrapnel head makes the test free of impurities, and the yield reaches 99.8%. As far as 3C lithium battery manufacturers are concerned, the characteristics of high-current lamellar micro-modules solve the problem of 3C lithium battery testing and provide a stable guarantee for testing. It can assist the orderly processing of 3C lithium batteries, both in terms of performance and cost performance.
