Abstract

This application is applicable to the field of battery technology, and provides a battery screening method, battery screening device, terminal equipment, and computer-readable storage medium, including: obtaining the charging and discharging curve of the battery to be screened; obtaining the charging and discharging curve of the battery to be screened; The voltage values ​​of the four preset time periods in the discharge curve; the voltage values ​​of the four preset time periods of the battery to be screened are respectively input into the corresponding K-means clustering result model, and the battery to be screened is respectively output The category numbers of the four preset time periods of the battery, wherein, a category number corresponds to a class; the category numbers of the four preset time periods of the battery to be screened are input to the trained random forest model, and the to-be-screened battery is output. The capacity group to which the battery belongs. The application can solve the problem that the battery cannot be screened in the prior art.

Description

technical field [0001] The present application belongs to the technical field of batteries, and in particular relates to a battery screening method, a battery screening device, terminal equipment and a computer-readable storage medium. Background technique [0002] Energy and the environment have become the most concerned issues in the world. Due to the consumption of oil resources and environmental pollution, traditional fuel vehicles are constantly being impacted by new clean energy vehicles. Electric vehicles replace oil with electricity and can achieve "zero emission" and "low noise", which is an important means to solve energy and environmental problems. With the shortage of petroleum resources and the development of battery technology, electric vehicles have gradually been popularized and applied all over the world. At present, electric vehicles are mainly based on lithium-ion batteries with high energy density. Judging from the current situation, lithium-ion batteri...
