Detailed ways

In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

Example 1

The smart charging device in this embodiment can be a mobile power supply or a portable charger. In some embodiments, the smart charging device in this embodiment can also be included in devices such as desktop computers and notebook computers. The intelligent charging device of this embodiment uses the charging method of this embodiment to achieve the purpose of charging different mobile terminals according to the charging priority of the charging port, and these all belong to the protection scope of this embodiment.

As shown in FIG. 1, FIG. 1 is a program flow chart of this embodiment. The charging method for the smart charging device of this embodiment, the smart charging device has a control unit and at least two charging ports respectively connected to the control unit, including the following steps:

S1: The control unit reads the current value of each charging port to detect whether there is a mobile terminal inserted into the charging port. If there is a current value, jump to step S2 and enter the charging process. If there is no current value in each charging port, the charging process ends;

S2: Each charging port determines the magnitude of the output current to different mobile terminals during the charging process according to the charging priority of each charging port set by the control unit.

As shown in FIG. 3 , FIG. 3 is a schematic block diagram of the structure of this embodiment. The smart charging device of this embodiment includes a control unit 1 and at least two charging ports 2 respectively connected to the control unit 1;

The control unit 1 reads the current value of each charging port 2 to detect whether there is a mobile terminal inserted into the charging port 2. If each charging port 2 has no current value, the charging process ends, and if there is a current value, the charging process starts: each charging port 2 according to The charging priority of each charging port 2 set by the control unit 1 determines the magnitude of the output current to different mobile terminals during the charging process.

The smart charging device in this embodiment has two charging ports, numbered as charging port 1 and charging port 2 , wherein the charging priority of charging port 1 is higher than that of charging port 2 . When a mobile terminal (such as a mobile phone) is plugged into charging port 1 or charging port 2, the control unit sets the output current of the charging port as the upper limit of the output current, for example, the upper limit of the output current is 2A, then the control unit The unit sets the output current of the charging port to 2 amps for charging, so as to achieve the purpose of fast charging. When two mobile terminals are plugged into charging port 1 and charging port 2 respectively, the two mobile terminals are charged according to the charging priority of the charging port, that is, the current output by the charging port is distributed, for example, charging port 1 distribution The current of charging port 2 is 1.2 amps, and the current distributed by charging port 2 is 0.8 amps, so that the current of charging port 1 is greater than the current of charging port 2, and the mobile terminal connected to charging port 1 is given priority to be fully charged first; of course, it can also be set The charging priority of the charging port 1 and the charging port 2 are the same, and at this time, the current output by the charging port is evenly distributed to charge the two mobile terminals. In other embodiments, the number of charging ports may also be other numbers greater than 2, such as 3, 5, etc., and the others are the same as in this embodiment.

Example 2

As shown in FIG. 2, FIG. 2 is a program flow chart of this embodiment. The charging method for the smart charging device of this embodiment, the smart charging device has a control unit and 5 charging ports respectively connected to the control unit, including the following steps:

S1: The control unit reads the current value of each charging port to detect whether there is a mobile terminal inserted into the charging port. If there is a current value, jump to step S2 and enter the charging process. If there is no current value in each charging port, the charging process ends;

S2: Each charging port determines the magnitude of the output current to different mobile terminals during the charging process according to the charging priority of each charging port set by the control unit.

Further, the step S2 includes two charging process modes, the balance mode and the sequence mode, and the two charging process modes will be described in detail below. Of course, it should be noted that, in other embodiments, one of the balanced mode and the sequential mode may also be used, and the others are the same as in this embodiment, and will not be repeated here.

Equilibrium mode consists of the following steps:

S2.11: Only one mobile terminal is connected to the charging port, then the control unit sets the output current of the charging port as the upper limit value of the output current to charge. For example, the upper limit of the output current is 3 amps, then the output current of the charging port is set to 3 amps, so that it can be charged quickly.

S2.12: Multiple mobile terminals are respectively connected to the charging ports, and the control unit divides the output current equally according to the detected number of mobile terminals, so that the output currents of the charging ports connected to the mobile terminals are equal in size, and the charging is performed. For example, if three mobile terminals are respectively connected to the charging ports, the control unit will divide the 3 A evenly, so that the output currents of the charging ports connected to the mobile terminals are all 1 A for charging.

The step S2.12 also includes the following steps:

S2.13: Detecting that the power of a mobile terminal reaches the first set value, the control unit reduces the output current of the charging port connected to the mobile terminal, and re-equalizes the output of other charging ports connected to the mobile terminal current for charging. For example, the size of the first set value can be set to 95% of the power of the mobile terminal, and when the power of the mobile terminal reaches 95% during charging, the control unit reduces the output current of the charging port connected to the mobile terminal , for example, it can be reduced from 1 amp to 0.6 amps, and then re-equally share the output current of other charging ports connected to the mobile terminal for charging. For example, if 3 mobile terminals are respectively connected to the charging port, the upper limit of the output current is 3 amps , when the power of a mobile terminal reaches 95% during the charging process, the control unit will reduce the output current of the charging port connected to the mobile terminal from 1A to 0.6A, and divide the remaining 2.4A equally, so that the other two The output current of the charging port connected with the mobile terminal is 1.2 amps.

S2.14: When it is detected that a new mobile terminal is connected to the charging port, the control unit re-equalizes the output currents of all the charging ports connected to the mobile terminal for charging. For example, there are 3 mobile terminals connected to the charging ports respectively, and the upper limit of the output current is 3 amps, and 2 mobile terminals are connected to the remaining 2 charging ports during the charging process, then the control unit will re-equalize all the charging ports with the mobile terminals. The output current of the connected charging port is 0.6A after re-equalizing, and it is 1A when there are 3 mobile terminals.

S2.15: When it is detected that the mobile terminal is pulled out of the charging port, the output current of the remaining charging ports connected to the mobile terminal is re-equalized for charging.

Sequential mode consists of the following steps:

S2.21: only one mobile terminal is connected to the charging port, then the control unit sets the output current of the charging port as the upper limit value of the output current for charging;

S2.22: Multiple mobile terminals are respectively connected to the charging port, and the output current of the charging port with a higher charging priority is greater than the output current of the charging port with a lower charging priority, so as to perform charging.

The step S2.22 further includes: detecting the rated current value of the mobile terminal connected to the charging port with the highest charging priority, and if it is greater than or equal to the upper limit value of the output current of the charging port, then the upper limit value to charge the mobile terminal, and other charging ports stop charging; if it is less than the upper limit value of the output current of the charging port, the output current value of the charging port is set as the base value of the rated current value, and the value greater than or equal to 1 times multiple; at the same time, the output current value of the charging port with the second highest charging priority is equal to the upper limit value of the output current minus the multiplied value. At this time, the rated current of the mobile terminal connected to the charging port with the second highest charging priority is detected Current value, if it is greater than or equal to the output current value of the charging port with the second highest charging priority, then charge the mobile terminal with the output current value of the charging port with the second highest charging priority, if it is less than the second highest charging priority If the output current value of the charging port is higher, the output current value of the charging port with the second highest charging priority is set as the product of the base value of the rated current value and the multiple of the value greater than or equal to 1 times; and so on, Set the output current of all charging ports to charge the mobile terminal.

For example, 3 mobile terminals are respectively connected to 3 of the 5 charging ports. For the convenience of expression, the 3 mobile terminals are respectively the first mobile terminal, the second mobile terminal and the third mobile terminal. The charging ports are respectively charging port 1, charging port 3 and charging port 5, wherein the charging priorities of the three charging ports are charging port 1, charging port 3 and charging port 5 in descending order. The upper limit of the output current of the charging port is 3A.

If the rated current value of the first mobile terminal is greater than or equal to 3 amps, such as 4 amps, then the charging port 1 charges the first mobile terminal with an output current upper limit of 3 amps; the charging port 3 and the charging port 5 stop charging.

If the rated current value of the first mobile terminal is less than 3 amps, such as 1.2 amps, then the output current value of the charging port 1 is the base value of the rated current value and the product of a multiple of a value greater than or equal to 1 times, such as charging The output current value of port 1 is 1.2A (the base is 1.2A, the multiple is 1 times) or 1.8A (the base is 1.2A, the multiple is 1.5 times).

Taking the output current value of the charging port 1 as 1.8A as an example to continue the description. At this time, the output current value of the charging port 3 is equal to the upper limit value of the output current minus the product number, that is, the value equal to 3 A minus 1.8 A, which is 1.2 A. The charging port 3 detects the rated current value of the second mobile terminal. If the rated current value is greater than or equal to 1.2 amps, such as 2 amps, the charging port 3 charges the second mobile terminal with a current of 1.2 amps. Charging port 5 with a low charging priority will stop charging; if the rated current value is less than 1.2 A, for example, 0.8 A, then the output current value of charging port 3 is set to 0.8 A as the base, and the value greater than or equal to 1 times The product of multiples, for example, the output current value of charging port 3 is 0.8A (the base is 0.8A, and the multiple is 1 times). Of course, the value of the multiple should not make the product greater than the output current value of charging port 3, which is 1.2A.

Continue the description with the output current value of the charging port 3 set to 0.8A. The charging port 3 repeats the above steps to set the output currents of all charging ports to charge the mobile terminal.

The step S2.22 also includes the following steps:

S2.23: It is detected that there is a new mobile terminal connected to the charging port, then re-perform step S2.22; of course, if in the state of step S2.21, it is detected that a new mobile terminal is connected to the charging port, then re-perform the step S2.22.

S2.24: Detecting that the power of a mobile terminal reaches the second set value, the control unit reduces the output current of the charging port connected to the mobile terminal, and repeats step S2.22. For example, the second set value can be set as 96% of the power of the mobile terminal, and when the power of the mobile terminal reaches 96% during charging, step S2.22 is performed again.

S2.25: It is detected that the mobile terminal is pulled out of the charging port, then step S2.22 is performed again.

Switching between the balanced mode and the sequential mode is performed through the mode switching switch set on the smart charging device. The mode status indicator light set on the smart charging device shows whether the charging process is equalization mode or sequential mode. When the smart charging device in this embodiment is charging, it can be charged by connecting to the mains, or it can be charged by the built-in rechargeable battery of the smart charging device.

The control unit 1 reads the current value of each charging port 2 to detect whether there is a mobile terminal inserted into the charging port 2.
