Abstract

The invention provides a battery sorting method. Batteries are sorted through three reference quantities of charging and discharging instantaneous internal resistance, battery capacity, and corresponding voltage values of different SOC of the batteries. The batteries with same parameters can be sorted accurately and reliably, so that the batteries with good conformance are assembled as a battery pack; the cycling life and charging and discharging performance of the matched battery pack are guaranteed so that the battery pack can supply electricity for electrical equipment safely, stably and efficiently; and the cycling life of the battery pack is prolonged, the charging and discharging performance of the battery pack is improved, so that cost of the battery pack is reduced.

Description

Technical field

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

[0002] As we all know, with the widespread use of fossil fuels, environmental pollution has become a worldwide problem. Disasters such as large areas of smog in the north, urban heat island effect, acid rain, etc. are sounding alarm bells time and time again for mankind. Therefore, with this increasingly serious environmental problem, the goal of finding an environmentally friendly energy source has become urgent. Environmental pollution and energy crisis are spurring 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 received extensive attention because of their extremely high electrical energy conversion efficiency without affecting the environment. At present, from small electrical equipment such as ...
