Abstract

The invention discloses a battery monomer sorting method. The method comprises the steps that n battery monomers are randomly selected from a to-be-sorted battery monomer set comprising N battery monomers to form a sample set; the open-circuit voltage Ui of each battery monomer in the sample set is collected; the minimum grouping group interval deltaU of the sample set is determined, and deltaU is equal to S / l, wherein S is preset sorting open-circuit voltage allowable deviation, and l is the preset positive integer; the minimum grouping group interval deltaU is used for grouping all group monomers in the sample set; grouped frequencies of all groups are calculated; the sorting open-circuit voltage allowable deviation S serves as the interval, l adjacent groups, with the maximum sum of the grouped frequencies, in the sample set are determined, the maximum upper end voltage of the determined l adjacent groups is determined as the sorting open-circuit voltage upper limit U1, and the minimum lower end voltage of the determined l adjacent groups is determined as the sorting open-circuit voltage lower limit U2; and according to the U1 and the U2, the to-be-sorted battery monomer set collected to be sorted and matched. The method is simple and easy to operate, the production efficiency can be greatly improved, and the production cost is saved.

Description

technical field [0001] The invention relates to electric vehicle manufacturing technology, in particular to a method for sorting battery cells. Background technique [0002] As the core component of electric vehicles, the power battery box provides the power source for electric vehicles. As the core part of the battery box, lithium-ion power battery cells are usually combined in different series and parallel to meet different voltage and power output requirements. There are differences in technical parameters such as capacity, voltage, and internal resistance among individual power battery cells. If the difference is too large, the distribution of operating voltage and operating current of each battery cell / battery module will be unbalanced, which will inevitably lead to battery / battery modules. Overcharge / overdischarge of the battery box, or the capacity is not saturated, and even cause battery safety issues. [0003] Therefore, it is necessary to select power battery cel...
