Embodiment Construction

[0052] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The exemplary described embodiments below do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with aspects of the present disclosure as recited in the appended claims.

[0053] At present, with the increase of the popularization rate of electronic devices, users' demand for fast charging is also higher and higher. Correspondingly, the accuracy of the charging method in the fast charging process is also becoming more and more important. In practical applications, considering that the number of pins on the battery connector is limited, the voltage sensing lines of the main charging circuit and the...

Abstract

The invention relates to a battery charging method and device, electronic equipment and a storage medium. The battery charging method comprises the steps that: a query request is sent to a voltameter in a battery, and the voltameter obtains charging data of a battery cell according to the query request and feeds the charging data back to a processor, wherein the charging data is voltage and / or current obtained by detecting the battery cell through a sensing line by the voltameter; charging data returned by the voltameter are received; and charging configuration information is generated according to the charging data, wherein the charging configuration information is used for configuring voltage and / or current provided for a charging module by a charging adapter. In the embodiment, the charging process is controlled by using the voltage of the battery cell, so that the battery voltage can be more accurately controlled, and the accuracy of the charging process can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of charging, and in particular to a battery charging method and device, electronic equipment, and a storage medium. Background technique [0002] At present, with the increase of the popularization rate of electronic devices, users' demand for fast charging is also higher and higher. Correspondingly, the accuracy of the charging method in the fast charging process is also becoming more and more important. In practical applications, considering that the number of pins on the battery connector is limited, the voltage sensing lines of the main charging circuit and the slave charging circuit in the electronic device can sense the voltage at the voltage detection point (pack point), according to the pack The voltage at the point charges the battery. [0003] Since there is a battery protection board between the battery cell terminal (cell point) and the battery connection terminal, there is a difference...
