Retired battery sorting method, device and equipment based on time distance sequence

The invention relates to a retired battery sorting method, device and equipment based on a time distance sequence, and the method comprises the steps: carrying out the charging and discharging pulse test of a first preset time for a plurality of retired batteries to be sorted, and obtaining a plurality of first voltage curves, performing a charge-discharge pulse test on the same type of new batteries for a second preset time to obtain a second voltage curve; calculating a time distance sequence in the first preset time according to the first voltage curve and the second voltage curve; predicting voltage curves of a plurality of to-be-sorted retired batteries in a third preset time based on the time distance sequence to obtain a plurality of third voltage curves of the third preset time; and calculating an average European deviation according to the third voltage curve, and sorting the retired batteries through the average European deviation. According to the method, the voltage curve of the decommissioned bat
