Embodiment Construction

[0034] It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0035] The main solution of the embodiment of the present application is: detect the DC impedance of the battery; according to the detected DC impedance of the battery and the charging cut-off current, set the charging cut-off voltage of the constant current charging stage during the current charging; The battery is charged. Therefore, by tracking the impedance change of the battery, adjusting the charging parameters in real time, and considering the correlation between the charging cut-off voltage and the impedance, when the impedance increases, the charging cut-off voltage is also increased accordingly, thus solving the problem that the charging time of the battery is getting worse as the battery ages. Longer questions.

[0036] The embodiment of the present application takes into account the i...

Abstract

The present application discloses a charging control method, device, terminal equipment and storage medium. The method includes: detecting the DC impedance of the battery; according to the detected DC impedance of the battery and the charging cut-off current, setting the constant current charging stage for the current charging The charging cut-off voltage; the battery is charged according to the set charging cut-off voltage. This application tracks the impedance change of the battery, adjusts the charging parameters in real time, and considers the correlation between the charging cut-off voltage and the impedance. longer question.

Description

technical field [0001] The present application relates to the technical field of charging, and in particular to a charging control method, device, terminal equipment, and storage medium. Background technique [0002] At present, the conventional charging scheme of the battery is the "constant current + constant voltage" charging mode, and the charging scheme remains constant throughout the life cycle of the product. This "constant current + constant voltage" conventional charging scheme, since the charging process is solidified throughout the charging process, the charging time will become longer and longer due to the gradual aging of the battery during actual use. Contents of the invention [0003] The main purpose of the present application is to provide a charging control method, device, terminal equipment and storage medium, aiming to solve the problem that the charging time of the battery becomes longer and longer as the battery ages. [0004] In order to achieve the...
