Embodiment 1

[0041] see figure 1 , this embodiment provides a charging control method, which is suitable for a terminal device with a built-in battery, including steps:

[0042] Step 101, when the terminal device enters the G0 working state, obtain the charging control parameter under the operating system, and charge the battery according to the charging control parameter; at the same time, write the obtained charging control parameter information into the register of the battery management chip to specify bit.

[0043] Repeated overcharging of the built-in battery of a terminal device such as a notebook computer will degrade the performance of the battery. For example, when fully charged for a long time, the actual capacity of the battery will decrease and the service life will be shortened.

[0044] For this reason, this embodiment will control the charging capacity of the battery to ensure that the maximum capacity of the battery is always lower than the total capacity of the battery ...

Embodiment 2

[0060] An embodiment of the present invention provides a terminal device, which includes: an embedded controller, a battery management chip, and a battery.

[0061] The embedded controller is used to obtain the charging control parameters input by the user under the operating system when the terminal device enters the G0 working state, perform charging control on the battery according to the charging control parameters, and write the obtained charging control parameter information into the battery The specified bit in the register of the management chip; it is also used to read the charging control parameter from the register of the battery management chip when the terminal device in the G3 mechanical shutdown state detects that the external power supply is connected, and according to the charging control parameter. The battery performs charge control.

[0062] The battery management chip can communicate directly with the embedded controller through SMBus (System Management Bu...

Embodiment 3

[0068] Those of ordinary skill in the art can understand that all or part of the steps in the various methods of the above embodiments can be completed by instructions, or by instructions controlling related hardware, and the instructions can be stored in a computer-readable storage medium, and loaded and executed by the processor.

[0069] To this end, an embodiment of the present invention provides a storage medium, in which a plurality of instructions are stored, and the instructions can be loaded by a processor to execute the steps in any one of the charging control methods provided by the embodiments of the present invention. For example, the command can perform the following steps:

[0070] When the terminal device enters the G0 working state, the charging control parameter is obtained under the operating system, and the battery is charged according to the charging control parameter; at the same time, the obtained charging control parameter information is written into th...

Abstract

The invention relates to the technical field of battery charging, and discloses a charging control method, terminal equipment and a storage medium. The charging control method comprises the steps: when the terminal equipment enters a G0 working state, obtaining charging control parameters under an operating system, and performing the charging control on a battery according to the charging controlparameters, and meanwhile, writing the charging control parameter information into a register of a battery management chip; detecting whether an external power supply is connected or not in a G3 mechanical shutdown state; when detection is carried out, reading the charging control parameters from the battery management chip, and continuously performing the charging control on the battery accordingto the charging control parameters. According to the invention, the readable and writable space in the battery management chip is used for storing the charging threshold value; when an external powersupply is plugged again after the terminal equipment enters the G3 mechanical shutdown state, the charging threshold value is actively read from the battery management chip, and the charging controlis continuously carried out according to the charging threshold value, so that charging control is automatically realized, and the overcharging of the battery is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of battery charging, in particular to a charging control method, terminal equipment and storage media. Background technique [0002] With the development of science and technology, functions of terminal devices (such as: notebook computers) become more and more powerful, and users can use the terminal devices for office work and entertainment, so that the terminal devices have become an indispensable part of people's daily life. However, the battery life of the terminal device is limited, and the user needs to charge the terminal continuously. [0003] During the charging process, if the charging is not effectively controlled, the battery of the terminal device may be overcharged, which will not only affect the service life of the battery, but also cause serious accidents such as spontaneous combustion and explosion of the battery. Contents of the invention [0004] The object of the present invention is ...
