Abstract

The invention discloses a battery sorting method and device, a computer readable storage medium and a processor. The method comprises the following steps of: determining a first characteristic point and a second characteristic point of a charging and discharging curve of a battery to be grouped; dividing the charging and discharging curve into three parts according to a starting point, the first characteristic point, the second characteristic point and an ending point of the charging and discharging curve, the curve between the starting point and the first characteristic point being a first polarization section, the curve between the first characteristic point and the second characteristic point being a platform section, and the curve between the second characteristic point and the endingpoint being a second polarization section; and sorting batteries to be grouped according to the platform sections. According to the battery sorting method and device, the computer readable storage medium and the processor, the technical problems of poor voltage difference, too fast capacity attenuation and short service life in the battery pack caused by different charging and discharging states of part of batteries due to various differences of performances between unit battery cells of the battery pack.

Description

technical field [0001] The present invention relates to the field of batteries, in particular to a battery sorting method, device, computer readable storage medium and processor. Background technique [0002] Due to the differences in product raw materials, process technology, precision and environmental control of lithium-ion batteries. In lithium-ion battery packs, there are always various differences in the performance of individual cells. During the charge-discharge cycle, this difference will gradually become prominent, causing some batteries to be in different charge-discharge states, resulting in problems such as poor pressure difference in the battery pack, rapid capacity decay and short lifespan. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present invention provide a battery sorting method, device, computer-readable storage medium, and processor to at least solve the problem ...
