Problems solved by technology

[0002] At present, mobile terminals (such as smart phones) are increasingly favored by consumers, but mobile terminals consume a lot of power and need to be charged frequently. Therefore, realizing fast charging is a key means to ensure the experience of mobile terminals. The accuracy of battery parameters collected by the fuel gauge function in the fast charging stage is low. Therefore, the existing charging system generally sets an external fuel gauge on the terminal to realize the collection of battery parameters. However, the external fuel gauge not only takes up the volume of the terminal , which is not conducive to the miniaturization of the terminal, and the cost is high

Embodiment Construction

[0023] Embodiments of the present application will be further described below in conjunction with the accompanying drawings. The same or similar reference numerals in the drawings represent the same or similar elements or elements having the same or similar functions throughout. In addition, the embodiments of the present application described below in conjunction with the accompanying drawings are exemplary, and are only used to explain the embodiments of the present application, and should not be construed as limiting the present application.

[0024] At present, the power of fast charging is getting bigger and bigger, and the charging speed is getting faster and faster, but at present, fast charging generally obtains battery parameters through an external fuel gauge, which will compare battery current, battery power and battery voltage. The calculation is stored in a specific register. The AP reads these specific registers through the interface of reading battery power, bat...

Abstract

The invention provides a charging control method. The charging control method comprises the steps of acquiring a first battery parameter of a terminal, wherein the first battery parameter is an analogsignal; converting the first battery parameter into a second battery parameter through a first analog-to-digital conversion module arranged in a microprocessor in an adapter; and controlling chargingparameters of the adapter for charging the terminal according to the second battery parameter. According to the charging control method provided by the embodiment of the invention, the first batteryparameter of the terminal is obtained; the battery parameter is subjected to analog-to-digital conversion through the first analog-to-digital conversion module arranged in the microprocessor to obtainthe accurate second battery parameter, an external voltameter does not need to be arranged at the terminal to obtain the battery parameter, miniaturization of the terminal is facilitated, and the cost is low. The invention further provides a charging control device, a charging system and a nonvolatile computer readable storage medium.

Description

technical field [0001] The present application relates to the technical field of charging, and in particular to a charging control method, a charging control device, a charging system and a non-volatile computer storage medium. Background technique [0002] At present, mobile terminals (such as smart phones) are increasingly favored by consumers, but mobile terminals consume a lot of power and need to be charged frequently. Therefore, realizing fast charging is a key means to ensure the experience of mobile terminals. The accuracy of battery parameters collected by the fuel gauge function in the fast charging stage is low. Therefore, the existing charging system generally sets an external fuel gauge on the terminal to realize the collection of battery parameters. However, the external fuel gauge not only takes up the volume of the terminal , which is not conducive to the miniaturization of the terminal, and the cost is relatively high. Contents of the invention [0003] E...
