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.

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 battery 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 or the wireless charging module 22 is connected to an external power source, the battery control circuit 23 controls the wired charging module 21 or the wireless charging module 22 connected to the external power source to simultaneously charge the first battery 24 and the second battery 25, so that the charging efficiency can be improved.

For example, when the wired charging module 21 is connected to an external power source, the battery control circuit 23 controls the first input port 231 to switch on the first output port 233 and the second output port 234, so that the wired charging module 21 can simultaneously charge the first battery 24 and the second battery 25.

For another example, when the wireless charging module 22 is connected to an external power source, the battery control circuit 23 controls the second input port 232 to switch on the first output port 233 and the second output port 234, so that the wireless charging module 22 charges the first battery 24 and the second battery 25 at the same time.

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 battery control circuit 23 controls the wired charging module 21 or the wireless charging module 22 connected to the external power source to alternately charge the first battery 24 or the second battery 25, so that heat generated by each battery in the whole charging process can be reduced.

For example, when the wired charging module 21 is connected to an external power source, the battery control circuit 23 may control the first input port 231 to alternately turn on the first output port 233 or the second output port 234. That is, the first input port 231 is switched on to the first output port 233 for a period of time, then switched on to the second output port 234, and then switched on to the first output port 233 after a period of time, and so on. Thus, it is possible to charge the first battery 24 for a certain period of time, to charge the second battery 25 again, to charge the first battery 24 again after a certain period of time, and so on.

For another example, when the wireless charging module 22 is connected to an external power source, the battery control circuit 23 may control the second input port 232 to alternately turn on the first output port 233 or the second output port 234. That is, the second input port 232 switches on the first output port 233 for a period of time, then switches on the second output port 234, and switches on the first output port 233 after a further period of time, and so on. Thus, it is possible to charge the first battery 24 for a certain period of time, to charge the second battery 25 again, to charge the first battery 24 again after a certain period of time, and so on.

In the third charging mode, when the wired charging module 21 and the wireless charging module 22 are both connected to an external power source, the battery control circuit 23 controls the wired charging module 21 to charge the first battery 24, and simultaneously the battery control circuit 23 also controls the wireless charging module 22 to charge the second battery 25, 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 battery control circuit 23 controls the first input port 231 to switch on the first output port 233, and controls the second input port 232 to switch on the second output port 234, so as to charge the first battery 24 through the wired charging mode and charge the second battery 25 through the wireless charging mode.

In some embodiments, as shown in FIG. 7, electronic device 100 also includes power control circuitry 26. The power supply control circuit 26 is connected to the first battery 24 and the second battery 25. Meanwhile, the power supply control circuit 26 is connected to a load in the electronic apparatus 100. Thus, the power supply control circuit 26 may be configured 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 control 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 control 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 control 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 control 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.

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.

The electronic equipment that this application embodiment provided both can charge through wired charging mode, also can charge through wireless charging mode to when at least one condition in wired charging and the wireless charging satisfies, for example when the user only need carry in charging adapter or the wireless base that charges, electronic equipment can charge, thereby can improve electronic equipment's convenience.

The electronic device provided by the embodiment of the application is described in detail above. The principles and implementations of the present application are described herein using specific examples, which are presented only to aid in understanding the present application. Meanwhile, for those skilled in the art, according to the idea of the present application, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present application.
