Abstract

The invention provides a sorting method of lithium ion power batteries. According to the sorting method, by means of three reference quantities of the lithium ion power battery capacity, the charge-discharge instant internal resistance and voltage values corresponding to battery different SOCs, the lithium ion power batteries are sorted, the lithium ion power batteries consistent in parameter can be sorted out accurately and reliably so that battery cells good in consistency can be assembled into battery packs, the cycle life and charge-discharge performance of the paired battery packs are guaranteed, and the battery packs can provide electricity for electric equipment safely, stably and efficiently; and the cycle life of the battery packs is prolonged, the charge-discharge performance of the battery packs is increased, and therefore the aim of reducing the cost of the battery packs 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 lithium-ion power 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 again and again for human beings. Therefore, under this increasingly serious environmental problem, the goal of finding an environment-friendly energy source has become urgent. Environmental pollution and energy crisis are driving the scientific research field to find new energy to solve these two problems.

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