What is the capacity of lithium battery? What are the uses of lithium battery capacity?

What is the capacity of lithium battery? The first explanation: Lithium battery capacity classification: a simple understanding is capacity classification, performance screening and classification. When the lithium battery is divided into capacity, the data of each test point is obtained through computer management, and the data such as the size and internal resistance of the battery can be decomposed to determine the quality level of the lithium battery. This process is the capacity classification. After the lithium battery is divided into capacity for the first time, it needs to stand for a period of time, generally no less than 15 days. During this period, some inherent quality problems will show up. The second explanation: After a batch of lithium batteries are completed, although the size is the same, the capacity of the batteries will be different. Therefore, it is necessary to overflow the device according to the specifications, and then discharge according to the specified current (discharge). The time it takes to discharge the battery multiplied by the discharge current is the battery capacity. Only if the detected capacity meets or exceeds the designed capacity, the lithium battery is qualified, and the battery less than the designed capacity cannot be regarded as a qualified battery. This process of screening qualified batteries through capacity detection is called capacity division. Lithium battery formation: generally refers to the implementation of a series of technological measures to stabilize the performance of the first-charged battery, including low-current charging and discharging, and constant temperature standing. What are the uses of lithium batteries? The processed lithium batteries cannot be sold immediately. They should be stored in the warehouse for at least 15 days. During this period, some inherent ills will appear, such as excessive self-discharge, etc. Curry batteries that have reached the shelf life, after receiving the order, take them out and test again and divide the capacity again, that is to say, charge and discharge again, and eliminate the batteries that are not up to the level or have quality problems, and then keep about 50%. The power of the battery is handed over to the sales department, and finally to the mobile phone battery block assembly plant. The batteries that will be used for lithium battery packaging are transformed into machine-differentiated batteries again. Through this process, some batteries that do not meet the requirements can always be picked out and returned to the battery factory. After the mechanical detection of the lithium battery test, it can be seen that the battery cell is charged and discharged again, and it is charged. Therefore, it is normal that there are two bars of electricity when the battery is received. Each channel of the battery capacity can be started and stopped at a single point, and the response speed is fast. Each channel has independent constant current source and constant voltage source, real-time sampling of current and voltage, constant current to constant voltage continuous switching without disturbance. Can be used for cycle life detection. To classify and group lithium batteries is to screen out the monomers with the same internal resistance and capacity for combination. When combined, only those with similar performance can form a lithium battery pack. For example, in order to meet the energy demand of electric vehicles, power lithium-ion battery packs often require dozens to thousands of batteries. Affected by the complexity of the system, the behavior of the battery pack has its magical properties, and it is not a single battery. Do a simple addition and subtraction to get the performance of the lithium battery pack. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
