Abstract

The invention relates to a lithium battery echelon utilization sorting method and device based on an IC curve. The method comprises the steps that image information of batteries to be sorted is obtained; carrying out primary screening according to the image information, and determining a corresponding first sorting battery; obtaining an IC curve obtained after the first sorting battery is charged and discharged; and inputting the IC curve into a completely trained neural network, and determining a corresponding second sorting battery. According to the method, the batteries are sorted from the aspects of external and internal aging mechanisms of the batteries by utilizing the IC curve and the image information, so that the sorted batteries have longer service life and better consistency, and the cascade battery pack has longer service life.

Description

technical field [0001] The present invention relates to the technical field of lithium-ion batteries, in particular to a step-by-step utilization and sorting method and device for lithium batteries based on IC curves. Background technique [0002] Due to the rise of the electric vehicle industry, the sales of electric vehicles have grown explosively, which has also led to an increase in the sales of lithium-ion power batteries. At the same time, the blowout development of electric vehicles has also led to a sharp increase in the number of batteries that need to be scrapped. For the power battery used in electric vehicles, in order to ensure that it meets the cruising range of electric vehicles, when the battery capacity drops to 80% of the original capacity, it needs to be eliminated from the vehicle. Direct elimination will cause waste of the remaining value of the battery At present, decommissioned echelon batteries can be used in communication base stations, home backup ...
