Introduction: 3C lithium batteries have the advantages of large capacity, good cycle life, and no memory effect. They are widely used in consumer electronic products. Because different electronic products require different voltages and capacities, lithium-ion batteries need to be used in series and parallel. The process of assembling 3C lithium battery cells into groups is called PACK, which can be a single battery or a series-parallel lithium battery pack. 3C lithium battery PACK means packaging, encapsulation, and assembly. Its process can be divided into three parts: processing, assembly, and packaging. It mainly assembles the battery cells, protection boards, connectors, packaging films, insulating auxiliary materials and other materials into battery packs through the pack processing technology. 3C lithium battery PACK is constantly developing towards large capacity, fast charging, long life and high safety. Therefore, higher requirements are also put forward for the performance test of 3C lithium battery PACK. When selecting a connection test module, it is necessary to consider large current transmission, test yield, cost control, etc. The large current shrapnel microneedle module developed by Kaizhitong as a connection test module not only meets the test requirements of large current, but also has better performance. 1 The large current shrapnel microneedle module is an integrated molding structure, flowing in the same material, with stable current transmission. In the 3C lithium battery PACK test, there will be no current attenuation, and it has good connectivity. 2 The maximum current that the large current shrapnel microneedle module can transmit is 50A, and the transmission is stable in the range of 1-50A, the resistance is constant, the current has no attenuation, and it has a good conduction effect. 3 In the field of small pitch, the minimum value of the large current shrapnel microneedle module is 0.15mm, between 0.15mm-0.4mm, with stable performance, no continuous pin and pin jam. 4. No puncture marks during the test. During the 3C lithium battery pack test, the high-current shrapnel microneedle module will not cause any damage to the connector. Before the test and after the test 20 times, the connector surface was placed under a 500x microscope and there were no puncture marks. It is safe to use. 5. The high-current shrapnel microneedle module has a service life of more than 20W times. It is a high-life connection test module, and it can also be customized according to the shape of the connector, with super adaptability! 6. The high-current shrapnel microneedle module has different test methods for different connectors. In the connector male seat test, the serrated shrapnel contacts the connector contact point to ensure stable testing. When testing the connector female seat, the shrapnel head is inserted into the connector terminal to create a certain amount of opening to ensure that the shrapnel contact surface is always in contact with both sides of the BTB connector terminal. The female seat test yield can reach 99.8%. The high-current shrapnel microneedle module has a long service life, strong current transmission capability, and stable and reliable connection. It is a powerful assistant for 3C lithium battery pack line testing. While ensuring test efficiency, it can effectively improve the test yield and solve the pain point of high test costs!
