Embodiment Construction

[0042] Below, specific embodiments of the present invention will be described in detail in conjunction with the accompanying drawings, but they are not intended to limit the present invention.

[0043] Embodiments of the present invention provide a fast charging control method and an electronic device, wherein the power supply mode provided by the USB port is judged by obtaining the remaining power of the power supply module of the USB port to charge the peripherals, and there is no need to charge each USB port The power supply is set separately, reducing the cost and also reducing the load on the electronic equipment.

[0044] Such as figure 1 As shown, it is a schematic flowchart of a fast charging control method in an embodiment of the present invention, which may include the following steps:

[0045] S1: Detect the access of peripherals;

[0046] Generally, a plurality of USB ports can be set in intelligent electronic devices such as computer equipment, and an embedded c...

Abstract

The invention provides a quick charging control method and electronic equipment. The quick charging control method comprises the following steps of S1, detecting peripheral equipment connection; S2, obtaining current residual power; and S3, adjusting a power supply mode of a USB port which is connected with the peripheral equipment according to the value of the residual power. By adoption of the embodiments, a quick charging function for the USB port can be realized without setting an extra power supply device.

Description

technical field [0001] The invention relates to the field of charging control, in particular to a fast charging control method and electronic equipment. Background technique [0002] As the performance of smart phones becomes more and more powerful and the battery technology is relatively backward, the dependence of smart phones on external power sources is getting stronger and stronger. And the USB port of our computer equipment in our daily office charges the mobile phone slowly, which is a problem that greatly affects the use of mobile phones with fragmented charging time. [0003] In the existing solution, the 5V current can be directly increased during design to increase the charging current of a single USB port, thereby increasing the charging speed. The disadvantage of this solution is that the number of fast charging ports is limited, and providing 5V current for each USB port will increase the load.
