What are the uses of lithium battery pack capacity?

Lithium battery pack capacity: a simple understanding is capacity sorting, performance screening and grading. Battery sub-capacity is to determine the capacity of the lithium battery pack by charging and discharging the battery, and by testing the discharge capacity when the sub-capacity is fully charged. When the lithium battery pack 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 battery. This process is the capacity classification. 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 be manifested, such as excessive self-discharge, etc., batteries that have reached the shelf life in the warehouse After getting the order, take it out and test again and divide the capacity again, that is, charge and discharge again, eliminate the capacity that does not reach the level or the quality problem, and then hand over to the sales department to maintain about 50% of the power. In the hands of the cell phone battery block assembly plant. The batteries that will be used for lithium battery packaging are converted into machine-divided capacity 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. So it is normal that there are two bars of electricity when the battery is received. Each channel of the lithium battery pack can be started and stopped at a single point, and the reaction 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. Disclaimer: Some pictures and content of the articles published on this site are from the Internet. If there is any infringement, please contact to delete.
