In the following embodiments of a fast charging system and method of the present invention, the described first electronic devices are all first electronic devices supporting an iOS operating system, such as an iPhone, an ipad, a notebook computer, and the like; in the following embodiments of the present invention, the above-mentioned contents are not further described. The first electronic device herein may be an intelligent mobile terminal; the second electronic device may be another intelligent mobile terminal.
As shown in fig. 1, fig. 1 is a functional module schematic diagram of an embodiment of the quick charging system of the present invention; the invention provides a quick charging system, comprising: a power adapter 100 and a controller 200 supporting a fast charging communication protocol; one end of the power adapter 100 is connected to a power supply, and the other end is connected to the controller 200; the controller 200 is connected with a first electronic device to be charged through a data line; thus, a complete charging scene in the actual application scene is formed.
In the rapid charging system of the present invention, the controller 200 and the power adapter 100 perform a fast charging protocol docking, and determine whether a first electronic device connected to the controller supports the fast charging protocol; that is, the controller 200 determines, based on the power adapter 100, whether or not a first electronic device communicatively connected to the controller 100 via a data line supports a fast charge protocol, and whether or not the first electronic device has a fast charge function corresponding to the fast charge protocol. If the first electronic device supports a fast charging protocol, the controller 200 obtains a voltage option that can be output by the power adapter 100; sending voltage demand information to the power adapter 100 according to the demand voltage of the first electronic device; the power adapter 100 outputs a corresponding voltage according to the power demand information to charge the first electronic device.
If the controller 200 determines that the first electronic device connected to the controller 200 does not support the fast charging protocol, the controller 200 sends corresponding charging control information to the power adapter 100; in a colloquial sense, the controller 200 sends general charging information to the power adapter 100; the power adapter 100 charges the first electronic device according to the charging control information sent by the controller 200 in a normal charging manner. That is, in this case, the first electronic device does not have the fast charging function corresponding to the fast charging protocol, and does not support the fast charging corresponding to the fast charging protocol. At this time, the power adapter 100 is used as a normal power adapter to provide a normal charging service for the first electronic device.
In a preferred embodiment of the present invention, the data line is a fast charging data line, and the described fast charging protocol includes but is not limited to: QC2.0 communication protocol; the QC2.0 is a Quick Charge 2.0 technology, and a charger (i.e., the power adapter 100 described in the embodiments of the present invention) which is specified by the QC2.0 protocol and can adaptively output 5V, 9V, or 12V is used to quickly Charge smart mobile devices such as mobile phones supporting the QC2.0 protocol. The QC2.0 technique can be understood simply as: the device outputs voltage signals to the charger through the USB data communication port D +/D-, and the charger is internally provided with a USB input decoding chip to judge the required output voltage of the charger, so that no special requirement is made on a charged USB line. In addition, the QC2.0 technology is divided into two industry standards of A level and B level; the A standard supports: 5V, 9V and 12V output voltages, and B standard supports: at present, most of first electronic devices (such as smart phones) supporting fast charging are all the a standards using QC2.0 technology, with output voltages of 5V, 9V, 12V and 20V. In the embodiment of the quick charging system of the present invention, the power adapter 100 is described as having all functions of the charger described above, and the first electronic device is specifically described by taking a mobile phone as an example.
In a specific application scenario of the rapid charging system of the present invention, when one end of the power adapter 100 is connected to the mobile phone through the controller 200 and the data line, the power adapter 100 short-circuits the D + and the D-by default, so that the mobile phone end detects that the charger type is DCP (dedicated charging port mode), and outputs 5V voltage by default, and the mobile phone charges normally. If the controller 200 determines that the mobile phone supports the QC2.0 fast charging protocol, a high voltage dedicated charging port (hvdcp) process of the power adapter 100 is started, and starts to load a voltage of 0.325V on D + and maintains the voltage for more than 1.25S. When the power adapter 100 detects that the voltage on D + is 0.325V and remains over 1.25S, the power adapter 100 disconnects the short circuit between D + and D-, and disconnects D + D-, so the voltage on D-no longer follows the voltage on D + by 0.325V, and the voltage will start to drop. When the mobile phone terminal detects that the voltage on the D-is reduced from 0.325V and is maintained to be more than 1MS, the hvdcp reads the maximum voltage value (/ sys/class/power supply/usb/voltage max) of the direct current power supply of the system, if 9000000mV, the voltage on the D + is set to be 3.3V, the voltage on the D-is set to be 0.6V, and if 5000000mV, the voltage on the D + is set to be 0.6V, and the D-is set to be 0V. When the power adapter 100 detects the voltages on D + and D-, it adjusts its output voltage to 9V or 5V.
In a preferred embodiment of the present invention, as shown in fig. 2, fig. 2 is a functional block diagram of an embodiment of a controller 200 in the quick charging system of the present invention; the controller 200 is divided according to functions and includes an adapter module 210 and a micro control unit 220; the adapter module 210 includes a USB-a port matched with the interface of the power adapter 100 and a USB-C port matched with the data line, and the micro control unit 220 is disposed between the USB-a port and the USB-C port, so that the controller 200 can be adapted to and connected to a general type of power adapter 100 without converting the interface, and can also be connected to the data line.
In a preferred embodiment of the present invention, the determining, by the controller 200, whether the first electronic device connected to the controller 200 supports the fast charging protocol includes:

For example, when the power amount of the first electronic device is greater than or equal to 80% of the total power amount, the controller 200 analyzes that the required voltage of the first electronic device is 5V, and sends corresponding control information to the power adapter 100, and the power adapter 100 outputs a voltage of 5V according to the control information sent by the controller 200; when the electric quantity of the first electronic device is less than 80% of the total electric quantity, the controller 200 analyzes and obtains that the required voltage of the first electronic device is 9V or 12V, and sends corresponding control information to the power adapter 100, and the power adapter 100 outputs the voltage of 9V or 12V according to the control information sent by the controller 200.
The quick charging system comprises a common power adapter supporting a quick charging protocol and a controller with a corresponding function, wherein the controller is used for judging whether a first electronic device in communication connection with the controller through a data line supports the quick charging protocol or not, and sending control information to the power adapter on the basis that the first electronic device supports the quick charging protocol, so that the first electronic device can be quickly charged by using the power adapter according to the actual requirement of the first electronic device, the aim of quickly charging the first electronic device using an iOS operating system by using the common power adapter is fulfilled, and the quick charging cost of the first electronic device using the iOS operating system is reduced.
