Referring to fig. 4, the ultra-low cost fast charging control method of two-in-one adapter and mobile power supply of the present invention is applied to the ultra-low cost fast charging device of two-in-one adapter and mobile power supply, and includes:

S2: entering a mobile power supply working mode, judging whether the first output module 10 is connected with a load or not, and judging whether the second input and output module 20 is connected with a load or charging equipment or not, and if not, putting the mobile power supply working mode in a standby state; if the load is connected, the control module 70 controls the corresponding switch to be turned on or turned off, so that the BAT power module 50 can realize single-port fast charging or double-port sharing output of the load; if the charging device is connected, the control module 70 controls the corresponding switch to be turned on or off, so as to realize the quick charging of the BAT power supply module 50 by the charging device, and repeat step S1.

Specifically, in the present embodiment, in the mobile power operation mode, the protocol IC module 60 is in the high-resistance state, and the third switch Q3 is in the off state.

Specifically, in the standby state, when the output port is loaded, the system enters a single-port fast-charging output state. At this time, the current path flows through the BUCK-BOOST module 30 by the BAT power module 50, and then flows to the connected load through the USB-A interface or the TYPE-C interface, and the conduction of the current path is realized by the control of the switch on the path by the control module 70.

When the single USB-A interface is used for fast charging and outputting, the control module 70 controls the first switch Q1 and the fifth switch Q5 to be turned on, and the second switch Q2, the fourth switch Q4 and the sixth switch Q6 to be turned off; when the single TYPE-C interface is used for fast charging output, the control module 70 controls the second switch Q2 and the fifth switch Q5 to be turned on, and controls the first switch Q1, the fourth switch Q4 and the sixth switch Q6 to be turned off.

Specifically, in the embodiment, in the single-port fast charging output state, when the other output port is connected to a load, the system enters a double-port 5V output working state. At this time, the control module 70 controls the first switch Q1, the second switch Q2, the fifth switch Q5 to be turned on, and the fourth switch Q4 and the sixth switch Q6 to be turned off, so that the current path flows from the BAT power supply module 50 through the BUCK-BOOST module 30, and then flows through the USB-ase:Sub>A interface and the TYPE-C interface to the connected load.

Specifically, in the present embodiment, in the adapter working mode, when the USB-ase:Sub>A interface and the TYPE-C interface are both connected without load, the control module 70 performs I2C protocol communication with the protocol IC module 60, the control module 70 controls the fourth switch Q4 and the fifth switch Q5 to be turned on, and the first switch Q1, the second switch Q2 and the sixth switch Q6 to be turned off, the protocol IC module 60 controls the third switch Q3 to be turned off, and the protocol IC module 60 outputs ase:Sub>A suitable voltage value of the front AC-DC module 40 through feedback voltage regulation according to the configuration, and charges the BAT power module 50 quickly viase:Sub>A the BUCK-BOOST module 30.

Specifically, in this embodiment, when the adapter is connected in the working mode without load, that is, when the AC-DC module 40 charges the BAT power module 50, if 220V AC is pulled out at this time, the system returns to the mobile power supply working mode.

In this embodiment, S4 is further included: in the adapter working mode, whether the single port is connected with the load or the double ports are connected with the load is judged, if the single port is connected with the load, the control module 70 controls the corresponding switch to be turned on or off, so that the BAT power module 50 is charged while the single port is charged quickly, if the double ports are connected with the load, the charging of the BAT power module 50 is cut off, the double ports are charged independently and quickly in the adapter working mode, and the step S3 is repeated.

Specifically, in the present embodiment, when only the USB-ase:Sub>A interface is connected to the load in the adapter working mode, the system enters ase:Sub>A state of fast charging output of the USB-ase:Sub>A interface alone in the adapter working mode, at this time, the control module 70 controls the first switch Q1, the fourth switch Q4, and the fifth switch Q5 to be turned on, and the second switch Q2, the sixth switch Q6 to be turned off, and the protocol IC module 60 controls the third switch Q3 to be turned off; while the USB-A interface is being quickly charged and output, the excess power from the AC-DC module 40 may be used to charge the BAT power module 50 viase:Sub>A the BUCK-BOOST module 30. The voltage output by the fast charge is subjected to I2C protocol communication with the protocol IC module 60 by the control module 70, and the front-end AC-DC module 40 outputs a voltage value meeting the protocol requirement through feedback voltage regulation.

Specifically, in the present embodiment, when only the TYPE-C interface is connected to the load in the adapter working mode, the system enters a state of fast charging output of the independent TYPE-C interface in the adapter working mode, at this time, the control module 70 controls the fourth switch Q4 and the fifth switch Q5 to be turned on, and the first switch Q1, the second switch Q2 and the sixth switch Q6 to be turned off, and the protocol IC module 60 controls the third switch Q3 to be turned on; the protocol IC module 60 automatically performs feedback voltage regulation on the AC-DC module 40 according to the fast charge protocol information applied by the load connected to the second input/output module 20, so as to obtain the fast charge output voltage meeting the requirement of the second input/output module 20. While the TYPE-C interface is rapidly charged and outputting, redundant electricity of the AC-DC module 40 is regulated by the BUCK-BOOST module 30 and then charges the BAT power module 50.

Specifically, when the two ports are simultaneously connected to the load in the working mode of the adapter in the embodiment, the two ports are supported to be simultaneously and rapidly charged and output. First, the control module 70 turns off the fifth switch Q5 to cut off the current path from the BUCK-BOOST module 30 to the BAT power module 50, and turns on the sixth switch Q6 to turn on the current path from the AC-DC module 40 to the BUCK-BOOST module 30. The protocol IC module 60 will turn on the third switch Q3, and automatically perform feedback voltage regulation on the AC-DC module 40 according to the load application protocol information accessed by the TYPE-C interface, and enable the front AC-DC module 40 to output a voltage value meeting the protocol requirements through feedback voltage regulation, thereby realizing the fast charging output of the TYPE-C interface. At the same time, the output voltage of the AC-DC module 40 also serves as the input voltage of the BUCK-BOOST module 30. The control module 70 turns on the first switch Q1 and processes the protocol information of the USB-ase:Sub>A interface, and configures the BUCK-BOOST module 30 to output ase:Sub>A voltage according with the output protocol of the USB-ase:Sub>A interface, thereby implementing the fast charging output of the USB-ase:Sub>A interface.

It can be seen that, the control module 70 controls the second switch Q2, the fourth switch Q4 and the fifth switch Q5 to be turned off, and the first switch Q1 and the sixth switch Q6 to be turned on, and the protocol IC module controls the third switch Q3 to be turned on, so that the BUCK-BOOST module 30 can be reused by adopting ase:Sub>A smart circuit structure design, and the AC-DC module 40 output voltage can be used as the input voltage of the BUCK-BOOST module 30 while meeting the TYPE-C interface fast charging voltage by cutting off the path between the BAT power module 50 and the BUCK-BOOST module 30, and the second fast charging voltage conforming to the USB-ase:Sub>A interface output protocol can be obtained after the BUCK-BOOST module 30 regulates voltage.

The above embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are intended to be within the scope of the present invention as claimed.
