It should be understood that the terms "first", "second", and the like, as described above, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit ly indicating a number of technical features being indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features.
In some embodiments, as shown in fig. 4, the wired charging module 21 includes a wired charging interface 211 and a wired charging management chip 212. The wired charging interface 211, the wired charging management chip 212, and the control circuit 23 are connected in sequence.
The wired charging interface 211 is used to connect an external power source, for example, the wired charging interface 211 may be used to connect a commercial power. The wired charging interface 211 may be an interface such as a Universal Serial Bus (USB).
The wired charging management chip 212 is configured to control the charging voltage and the charging current input by the wired charging module 21.
In some embodiments, as shown in fig. 5, the number of the wired charging management chips 212 is at least two, and may be 2, for example.

During the charging process of the wired charging module 21, the wired charging management chip 212 generates heat, which may affect the functions of the electronic device 100. When the plurality of wired charging management chips 212 are connected in parallel, the plurality of wired charging management chips 212 can play a role in shunting, so that the total heat productivity in the wired charging process can be reduced, and the influence on the electronic device 100 in the charging process is reduced.
In some embodiments, with continued reference to fig. 5, the wireless charging module 22 includes a receiving antenna 221, a wireless receiving chip 222, and two wireless charging management chips 223.

Wherein the receiving antenna 221 may comprise a receiving coil. The receiving antenna 221 is configured to be connected to an external power source by way of electromagnetic coupling, so that power can be received through the receiving antenna 221. For example, the receiving antenna 221 may be connected to a wireless charging base by electromagnetic coupling, and the wireless charging base may be connected to the commercial power. The wireless charging base can convert commercial power into a high-frequency alternating current signal and radiate the high-frequency alternating current signal to the outside in an electromagnetic wave mode.

At this time, the receiving antenna 221 may receive a high-frequency alternating current signal radiated to the outside by the wireless charging base, so that the receiving antenna 221 receives electric energy.
The wireless receiving chip 222 is configured to convert a wireless charging signal received by the receiving antenna 221. The receiving antenna 221 is connected to an external power source through an electromagnetic coupling method, so that the wireless charging signal received by the receiving antenna 221 is a high-frequency alternating current signal.

In some embodiments, the number of the wireless charging management chips 223 is at least two, and may be 2, 3 or more, for example. Taking 3 as an example, as shown in fig. 6, in this embodiment, the number of the wireless charging management chips 212 includes three, such as a first wireless charging management chip 223, a second wireless charging management chip 223, and a third wireless charging management chip 223, wherein the first wireless charging management chip 223, the second wireless charging management chip 223, and the third wireless charging management chip 223 are connected in parallel.
That is, the input end of each wireless charging management chip 223 is connected to the wireless receiving chip 222, and the output end of each wireless charging management chip 223 is connected to the control circuit 23.
During the charging process of the wireless charging module 22, the wireless charging management chip 223 generates heat, which may affect the function of the electronic device 100. When the plurality of wireless charging management chips 223 are connected in parallel, the plurality of wireless charging management chips 223 can play a role in shunting, so that the total heat productivity in the wireless charging process can be reduced, and the influence on the electronic device 100 in the charging process is reduced.
In this embodiment, the electronic device 100 may be charged by a plurality of charging methods. The specific description is as follows.
In the first charging mode, when the wired charging module 21 and the wireless charging module 22 are both connected to an external power source, the control circuit 23 controls the wired charging module 21 and the wireless charging module 22 to respectively charge the first battery 24 and the second battery 25 according to the remaining power of the first battery 24 and the second battery 25 and the charging power of the wired charging module 21 and the wireless charging module 22, so that the charging efficiency can be improved.
For example, when the wired charging module 21 and the wireless charging module 22 are both connected to an external power source, the remaining capacities of the first battery 24 and the second battery 25 are compared, and if the remaining capacity of the first battery 24 is greater than the remaining capacity of the second battery 25 and the charging power of the wired charging module 21 is greater than that of the wireless charging module 22, the control circuit 23 may control the first input port 231 to be connected to the second output port 234, and the second input port 232 to be connected to the first output port 233, so that the wired charging module 21 charges the second battery 25, and the wireless charging module 22 charges the first battery 24.
For another example, when the wired charging module 21 and the wireless charging module 22 are both connected to an external power source, if the remaining capacity of the first battery 24 is greater than the remaining capacity of the second battery 25, and the charging power of the wired charging module 21 is less than that of the wireless charging module 22, the control circuit 23 may control the first input port 231 to be connected to the first output port 233, and the second input port 232 to be connected to the second output port 234, so that the wired charging module 21 charges the first battery 24, and the wireless charging module 22 charges the second battery 25.
For another example, when the wired charging module 21 and the wireless charging module 22 are both connected to an external power source, if the remaining capacity of the first battery 24 is less than the remaining capacity of the second battery 25, and the charging power of the wired charging module 21 is greater than that of the wireless charging module 22, the control circuit 23 may control the first input port 231 to be connected to the first output port 233, and the second input port 232 to be connected to the second output port 234, so that the wired charging module 21 charges the first battery 24, and the wireless charging module 22 charges the second battery 25.
In the second charging mode, when the wired charging module 21 or the wireless charging module 22 is connected to an external power source, the control circuit 23 controls the wired charging module 21 or the wireless charging module 22 connected to the external power source to charge the first battery 24 or the second battery 25 according to the remaining power of the first battery 24 and the second battery 25.
For example, when the wired charging module 21 is connected to an external power source, if the remaining capacity of the first battery 24 is greater than the remaining capacity of the second battery 25, the control circuit 23 may control the first input port 231 to connect the second output port 234, so as to charge the second battery 25 in advance, and after the second battery 25 is fully charged, the control circuit 23 may control the first input port 231 to connect the first output port 233, so as to charge the first battery 24.
For another example, when the wireless charging module 22 is connected to an external power source, if the remaining capacity of the first battery 24 is less than the remaining capacity of the second battery 25, the control circuit 23 may control the second input port 232 to connect the first output port 233, so as to charge the first battery 24 in advance, and after the first battery 24 is fully charged, the control circuit 23 may control the second input port 232 to connect the second output port 234, so as to charge the second battery 25.
In some embodiments, as shown in FIG. 7, electronic device 100 also includes power supply circuitry 26. Wherein, the power supply circuit 26 is connected with the first battery 24 and the second battery 25. Meanwhile, the power supply circuit 26 is connected to a load in the electronic apparatus 100. Thus, the power supply circuit 26 may be used to control at least one of the first battery 24 and the second battery 25 to supply power to the electronic device 100.
For example, the power supply circuit 26 may control the first battery 24 to supply power to the electronic device 100, may control the second battery 25 to supply power to the electronic device 100, and may control the first battery 24 and the second battery 25 to supply power to the electronic device 100 at the same time.
In the first charging mode, when the first battery 24 and the second battery 25 are charged simultaneously by a wired charging mode or a wireless charging mode, the power supply circuit 26 may control the first battery 24 and the second battery 25 to simultaneously supply power to the electronic device 100.
In the second charging mode, when one of the first battery 24 and the second battery 25 is charged by a wired charging mode or a wireless charging mode, the power supply circuit 26 may control the battery being charged to supply power to the electronic device 100. For example, when the first battery 24 is in a charged state, the electronic device 100 may be controlled to be powered by the first battery 24; when the second battery 25 is in the charging state, it is possible to control the power supply of the electronic apparatus 100 by the second battery 25.
In the third charging mode, when the first battery 24 and the second battery 25 are charged by the wired charging mode and the wireless charging mode at the same time, the power supply circuit 26 may control power to be supplied to the electronic device 100 from any one of the first battery 24 and the second battery 25, or may control power to be supplied to the electronic device 100 from both the first battery 24 and the second battery 25. It should be understood that the terms "first", "second", and the like, as described above, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit ly indicating a number of technical features being indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features.
In addition, in the embodiment of the present application, when neither the first battery 24 nor the second battery 25 is in the charging state, the electronic device 100 may be powered by one battery first. For example, the electronic device 100 may be powered by the first battery 24. When the battery power for powering the electronic device 100 is about to be exhausted, for example, the first battery 24 is about to be exhausted, the electronic device 100 may control the system to enter a low power consumption state, where the power consumption of the electronic device is low. The electronic device then controls the connection of the further battery to the system side via a smaller resistance (e.g. 100 ohms), for example controls the connection of the second battery 25 to the system side. The electronic device then controls the battery to be drained off, for example the first battery 24. Finally, the electronic device controls the short-circuiting of the resistance to supply power to the electronic device via the further battery, for example via the second battery 25. Thus, the electronic device 100 may implement a switch from being powered by one battery to being powered by another battery.
