Abstract

The invention provides a cell sorting method. Cells are sorted through three reference quantities of the cell capacity, the charge / discharge instant internal resistance and different cell SOC corresponding voltage values, so that the cells with consistent parameters can be accurately and reliably sorted, the cells with good consistency can be assembled as cell sets, the circulating life and the charge / discharge performances of the mated cell sets are guaranteed, the cell sets can safely, stably and efficiently supply electricity to power use equipment, the circulating life of the cell sets is prolonged, the charge / discharge performances of the cell sets are improved, and the purpose of reducing the costs of the cell sets is achieved.

Description

technical field

[0001] The invention relates to the technical field of battery detection and sorting, in particular to a sorting method for single batteries. Background technique

[0002] As we all know, with the widespread use of fossil fuels, environmental pollution has become a worldwide problem. Large areas of smog in the north, urban heat island effect, acid rain and other disasters are sounding the alarm for human beings again and again. Therefore, under the increasingly serious environmental problems, the goal of finding an environmentally friendly energy source has become urgent. Environmental pollution and energy crisis are spurring the field of scientific research to find new energy sources to solve these two major problems.

[0003] Batteries, as a storage and conversion carrier of electrical energy, have attracted extensive attention because of their extremely high electrical energy conversion efficiency without affecting the environment. At present, from small...
