Battery cascade utilization sorting method, device and equipment and storage medium

The invention relates to the technical field of secondary batteries, and discloses a battery echelon utilization sorting method, device and equipment and a storage medium, and the method comprises the following steps: carrying out constant current charging on an initial single battery after a battery module is disassembled, and obtaining target battery data; performing feature extraction on the target battery data, and determining the estimated capacity of the initial single battery according to the obtained battery features; obtaining a quality detection result corresponding to the initial single battery based on the target battery data; and determining a target battery in the initial single batteries according to the quality detection result and the estimated capacity. Compared with an existing battery sorting method, the method has the advantages that battery sorting can be carried out based on the fragment type battery charging data under the condition that historical data is missing, the sorting duration
