Problems solved by technology

[0002] With the rise of various terminal electronic devices such as high-configuration large screens, the battery life of the built-in lithium battery is often insufficient, which has become a current problem. The mobile power supply is a solution to this deficiency, but the current The output current of the mobile power supply is generally not more than 2.4A, and the input current is generally limited to more than 2A, which makes charging the mobile power supply or using the mobile power supply to charge the terminal electronic equipment slower, causing inconvenience in use

Embodiment Construction

[0026] An embodiment of the present invention firstly provides a method for fast charging of a mobile power supply, the method includes a method of using an adapter to quickly charge a mobile power supply and a method of using a mobile power supply to charge a terminal electronic device, wherein,

[0027] a1, the power adapter is connected to the mobile power supply, and the input mode control module turns on the normal current charging mode to charge the lithium battery;

[0028] a2, the communication identification module communicates with the power adapter to shake hands to identify whether the power adapter supports high-current fast charging mode;

[0029] a3, in step a2, if the high-current fast charging mode is supported, adjust the input mode control module to select the high-current charging mode to charge the lithium battery; if the high-current fast charging mode is not supported, maintain the original normal current charging mode;

[0030] a4. The monitoring and co...

Abstract

The invention discloses a rapid charging method and system for a portable power source. A communication recognition module is connected to a power adaptor or terminal electronic equipment for recognizing whether to support a large-current charging mode, an input mode control module and an output mode control module are connected with the communication recognition module simultaneously, and a charging input mode or a charging output mode is selected according to a recognition result of the communication recognition module, so that the portable power source is charged or the portable power source is used for charging the terminal electronic equipment. According to the method and the system, the input and output current can be intelligently selected and controlled, and 2-5A large current can be supplied to increase the charging speed and shorten the charging time; when the electronic equipment is charged, the voltage-reduction scheme is adopted to improve the charging efficiency; a monitoring confirmation module is additionally arranged, thus well ensuring the charging safety and preventing safety risk.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a fast charging method and system for a mobile power supply. Background technique [0002] With the rise of various terminal electronic devices such as high-configuration large screens, the battery life of the built-in lithium battery is often insufficient, which has become a current problem. The mobile power supply is a solution to this deficiency. The maximum output current of the mobile power supply is generally not more than 2.4A, and the input current is generally limited to more than 2A, which makes charging the mobile power supply or using the mobile power supply to charge the terminal electronic equipment slower, causing inconvenience in use. Contents of the invention [0003] The object of the present invention is to provide a method and system for fast charging of a mobile power supply to address the shortcomings of the above technical solutions. [0004] The presen...
