Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a charging method for automatically adjusting a charging current according to an embodiment of the present invention. The present embodiment may be applicable to a case where the charging current needs to be automatically adjusted, and the method may be performed by an automatic charging current adjusting apparatus, which may be implemented by software and/or hardware. The method specifically comprises the following steps:

Specifically, the terminal device refers to a device that inputs a program and data to a computer via a communication facility, or receives a processing result output by the computer. The terminal equipment is usually set in a convenient place where it can be connected with remote computer by means of communication equipment, and is mainly formed from communication interface control device and special-purpose or selected input and output device. During the charging process of the terminal device, the temperature of the terminal device gradually increases as the charging time becomes longer. The temperature rise mainly originates from two components, namely the battery and the motherboard. The battery can store electric energy during charging so as to supply power to the terminal equipment. The main board provides a carrier or platform for the hardware of the terminal device, and integrates various operation management functions of the mobile phone.

The first temperature threshold is preset by the system according to the performance of the terminal device, for example, the first temperature threshold may be 45 ℃, that is, when the battery temperature is less than 45 ℃, the charging current is adjusted according to the temperature of the motherboard, for example, different charging currents may be set for different temperatures of the motherboard, so that the magnitude of the charging current changes with the change of the temperature of the motherboard.
Preferably, the charging is stopped when the voltage of the battery charged to the terminal device reaches a first voltage threshold.
In the charging process of the terminal equipment, the voltage of the terminal equipment can be gradually increased along with the increase of the charging time. A first voltage threshold is preset, and when the battery voltage of the terminal device reaches the first voltage threshold during charging, the charging is stopped, for example, the first voltage threshold may be a full-charge voltage of the battery of the terminal device, and in this embodiment, the first voltage threshold is 4.35V, where V is a voltage unit volt. The battery temperature is too high due to the fact that the voltage is too high, and the charging is stopped when the voltage of the battery reaches the first voltage threshold value, so that the protection of the terminal equipment and the safety of the charging process are improved.

After the battery temperature and the mainboard temperature in the charging process of the terminal equipment are detected, the temperature of the battery is judged, optionally, the temperature of the mainboard is not considered any more, and the charging is stopped as long as the battery temperature is greater than the first temperature threshold value. For example, the first temperature threshold may be 45 ℃. When the temperature of the battery is too high, the terminal equipment is stopped to be charged, so that the protection of the terminal equipment and the safety of the charging process are improved.
Preferably, when the battery temperature is lower than a first temperature threshold, if the mainboard temperature is higher than a third temperature threshold, the charging is stopped.
When the battery temperature is judged to be smaller than the first threshold value, the mainboard temperature is continuously judged, and if the mainboard temperature is larger than a third temperature threshold value, the charging is stopped. Illustratively, the third temperature threshold may be 60 ℃. The terminal equipment is easily burnt out due to overhigh temperature of the mainboard, and the charging is stopped when the temperature of the mainboard is overhigh, so that the safety of the terminal equipment and a user is protected.
The embodiment of the invention detects the battery temperature and the mainboard temperature of the terminal equipment in the charging process; and when the battery temperature is smaller than a first temperature threshold value, adjusting the charging current according to the temperature of the mainboard. The problem that the local temperature is higher and the safety of a user is not facilitated due to the fact that large current charging is achieved is solved, the temperature of the terminal equipment is prevented from rising too fast, and the purpose of improving charging safety in the charging process is achieved.

In the charging process, if the terminal equipment is not used, a large charging current is applied for charging, and if the terminal equipment is in use, a small charging current is applied for charging.

The application program is a program for completing one or more specific works, operates in a user mode, can interact with a user, has a visual user interface, and is a part of programs provided for meeting application requirements of the user in different fields and different problems. Illustratively, the system program may be a calendar, file management, etc., and the application program may be a WeChat, QQ, browser, etc.
The terminal device is not used, including that both a system program and an application program in the terminal device are in a closed state, the terminal device is in use, including that at least one system program or application program in the terminal device is in an open state, for example, when a user is using a chat function of WeChat, and the WeChat is in the open state, it indicates that the terminal device is in use.
