Specifically, the mobile power supply control method provided in the present embodiment is applied to the mobile power supply of the above embodiment.
When a user needs to use a mobile power supply to wirelessly charge the electronic device, an external device to be charged is placed on the mobile power supply, a receiving coil in the external device is correspondingly placed at a position of the transmitting coil 600, the wireless charging control unit 310 scans and identifies that the device side is in wireless charging control, the device side is in wireless charging control to request the wireless charging control unit 310 to output corresponding power according to the working state of the device side, and the wireless charging control unit 310 sends the first power supply requirement to the main control module 100 according to the power required by the external device after receiving the power request of the wireless charging control of the device side. When the main control module 100 receives the first power supply requirement and the second power supply requirement, the main control module 100 generates a power allocation signal according to a preset allocation rule, and sends the power allocation signal to the dc conversion module 200. At this time, the preset allocation rule may include, for example: when the first request power of the first power supply requirement is not zero, the second request power of the second power supply requirement is zero, and the first request power is set to be the first target power. The main control module 100 receives the first power supply requirement, generates a first power allocation signal according to a first request power set in the first power supply requirement, and the first power allocation signal may, for example, include setting the first request power in the first power supply requirement to be a first target power, and sends the first power allocation signal to the dc conversion module 200, where the dc conversion module 200 converts the current provided by the battery 700 into the first target power according to the first power allocation signal, and outputs the first target power to the wireless charging control unit 310 through the wireless charging power output unit 320, so as to wirelessly supply power to the external device.
When a user needs to use the mobile power supply to perform wired charging on the electronic device, and the external device to be charged is connected to the mobile power supply through the wired interface, the power supply protocol unit 410 communicates with the main control module 100, and the power supply protocol unit 410 sends a second power supply requirement to the main control module 100 through the charging protocol to request to output the required current. When the main control module 100 receives the first power supply requirement and the second power supply requirement, the main control module 100 generates a power allocation signal according to a preset allocation rule, and sends the power allocation signal to the dc conversion module 200. At this time, the preset allocation rule may include, for example: when the first request power of the first power supply requirement is zero, the second request power of the second power supply requirement is not zero, and the second request power is set to be a second target power. The main control module 100 receives the second power supply requirement, generates a second power allocation signal according to a second request power in the second power supply requirement, where the second power allocation signal may, for example, include setting the second request power in the second power supply requirement to be a second target power, and sends the second power allocation signal to the dc conversion module 200, and the dc conversion module 200 converts the current provided by the battery 700 into the second target power according to the second power allocation signal, and performs wired power supply to the external device through the wired power output unit 420.

The preset allocation rule comprises the following steps: obtaining the maximum value of power supply power; when the sum of the first request power of the first power supply requirement and the second request power of the second power supply requirement is smaller than or equal to the maximum value of the power supply power, setting the first request power as a first target power and setting the second request power as a second target power; when the sum of the first request power and the second request power is larger than the maximum value of the power supply power, the second request power is set to be a second target power, and the difference between the maximum value of the power supply power and the second request power is set to be a first target power. The main control module 100 controls the direct current conversion module 200 to output the current of the required power for the wired power supply module 400 according to the power supply requirement of the wired power supply module, and outputs the remaining power current to the wireless power supply module 300 according to the maximum value of the power supply power. Of course, the preset allocation rule may also include, for example, preferentially meeting the power supply requirement of the wireless power supply module, and the main control module 100 controls the dc conversion module 200 to output the current of the required power for the wireless power supply module 300, and then outputs the remaining power current to the wired power supply module 400 according to the maximum value of the power supply power. The preset allocation rule may be set according to actual requirements, which is not limited in this embodiment.
In one implementation manner of this embodiment, before the main control module generates a power allocation signal according to the first power supply requirement and the second power supply requirement, and sends the power allocation signal to the dc conversion module, the method further includes: the main control module sends a default power allocation signal to the direct current conversion module, and the direct current conversion module outputs default power to the wireless power supply module and the wired power supply module respectively according to the default power allocation signal. The default power may be, for example, 1/2 of the maximum value of the power supply, and when the maximum value of the power supply is 12W, the default power may be, for example, 5W. The main control module 100 sends a default power allocation signal to the direct current conversion module 200, and the direct current conversion module 200 outputs current with default power to the wireless charging power output unit 320 according to the default power allocation signal, so that the external device can be electrified when being connected to the mobile power supply; and then the main control module 100 and the wireless charging control unit 310 communicate with each other to output high power current required by the external device. The main control module 100 sends a default power allocation signal to the direct current conversion module 200, and the direct current conversion module 200 outputs a default power current to the wired power output unit 420 according to the default power allocation signal, so that the external device can be electrified when being connected to the mobile power supply; and then the main control module 100 and the power supply protocol unit 410 communicate with each other to output high power current required by the external device.

Specifically, when a user needs to wirelessly charge the electronic device using the mobile power supply, an external device to be charged is placed on the mobile power supply, and when the user also needs to charge the mobile power supply, the wired interface is connected to the mobile power supply. For example, a wired charge is connected first and then a wireless power supply is connected, or a wireless power supply is connected first and then a wired charge is connected. At this time, the main control module 100 receives the first power supply requirement and the charging power requirement, and the main control module 100 generates a power allocation signal according to a preset allocation rule, the first power supply requirement and the charging power requirement, and sends the power allocation signal to the dc conversion module, so as to dynamically allocate wired charging and wireless power supply, thereby ensuring stable and balanced overall operation. In this embodiment, the preset allocation rule may be, for example, to preferentially satisfy the requirement of charging the mobile power supply, and if the power input by the charging module cannot simultaneously satisfy the wired input and the wireless power supply, the main control module 100 preferentially controls the dc conversion module 200 to provide the current of the required power for the charging module, and then outputs the remaining power current to the wireless power supply module 300 according to the maximum value of the power supply power. Specifically, the preset allocation rule may, for example, include acquiring a power supply power maximum value; and judging the relation between the first request power and the third request power and the maximum value of the power supply power so as to keep dynamic balance of charging and discharging of the mobile power supply. When the sum of the first request power of the first power supply requirement and the third request power of the charging power requirement is smaller than or equal to the maximum value of the power supply power, setting the first request power as a first target power and setting the third request power as a third target power; when the sum of the first request power and the third request power is larger than the maximum value of the power supply power, the third request power is set to be a third target power, and the difference between the maximum value of the power supply power and the second request power is set to be a first target power. Of course, the preset allocation rule may be set according to actual requirements, which is not limited in this embodiment.
