Embodiment Construction

[0060] Firstly, a battery charging control method implemented in an embodiment of the present invention is described, including:

[0061] When a power supply is detected, determine whether the battery power is lower than the safety cut-off power;

[0062] If not, select the control mode, the control mode includes three modes, namely: power supply mode, sleep mode and charging mode, wherein the power supply mode refers to supplying power to the electric device without charging the battery; The sleep mode refers to charging the battery when the user does not operate, and supplies power to the electric device when the user operates; the charging mode refers to charging the battery.

[0063] In order to enable those skilled in the art to better understand and implement the technical solutions provided by the present invention, the following will be described in detail with reference to the accompanying drawings.

[0064] see Figure 2a , which is a flow chart of Embodiment 1 of ...

Abstract

The invention provides a battery charging control method, device and system. The method comprises: when it is detected that there is a power access, determining whether the electric quantity of a battery is lower than a safety cut-off electric quantity; and if no, selecting a control mode, wherein the control mode comprises there modes which are respectively a power supply mode, a dormancy mode and a charging mode, the power supply mode means that power is supplied to an electrical device and the battery is not charged, the dormancy mode means that the battery is charged in case there is no user operation and the power is supplied to the electrical device in case there is user operation, and the charging mode means that the battery is charged, such that the control mode for charging the battery is enriched, the problem of charging the battery when a user need is uncertain is solved, and the damage caused to the battery in case that a charging coefficient is too high. Besides, the user can freely select the control mode, such that the demands of different population groups can be satisfied.

Description

technical field [0001] The invention relates to the technical field of battery control, in particular to a battery charging control method, device and system. Background technique [0002] With the development of technology, people rely more and more on mobile devices, such as mobile phones and tablet computers. With the high-intensity use of the mobile device, sometimes the mobile device needs to be charged once in half a day. The life of existing rechargeable batteries depends on the number of times of charging and discharging, and the battery capacity of most rechargeable batteries has dropped significantly after 300 times of charging and discharging. [0003] Currently, when a mobile device is connected to an adapter, it follows the figure 1 The flow shown is for charging. Combine below figure 1 Now, how to control battery charging in the prior art will be introduced. [0004] S101: Detecting that an adapter is connected; [0005] S102: When judging that the batter...
