Referring to fig. 5, fig. 5 is a schematic structural diagram of an electronic device according to an embodiment of the present disclosure. The electronic apparatus 100 includes: a wired charging module 21, a wireless charging module 22, a battery control circuit 23, a first battery 24, and a second battery 25.

The wired charging module 21 may be connected to an external power source through a cable, that is, connected to the external power source through a wired connection. The wireless charging module 22 may be connected to the external power source in a wireless manner, for example, by electromagnetic coupling.

The battery control circuit 23 is connected to the first battery 24, the second battery 25, the wired charging module 21, and the wireless charging module 22.

When the output terminal of the wired charging module 21 outputs the first charging signal, the battery control circuit 23 sets the first battery 24 and the second battery 25 in parallel, and connects the output terminal of the wired charging module 21 with the first battery 24 and the second battery 25 connected in parallel with the first battery 24.

When the output terminal of the wireless charging module 22 outputs the second charging signal and the output terminal of the wired charging module 21 does not output the first charging signal, the battery control circuit 23 serially connects the first battery 24 and the second battery 25, and connects the output terminal of the wireless charging module 22 with the first battery 24 and the second battery 25 serially connected with the first battery 24.

It is understood that the electronic device 100 includes two charging modes, namely a wired charging mode for charging the first battery 24 and the second battery 25 through the wired charging module 21 and a wireless charging mode for charging the first battery 24 and the second battery 25 through the wireless charging module 22. For the wireless charging mode, the problem is that heat is generated at present. The heat generation source mainly comes from three aspects: a receiving coil, a wireless receiving chip, and a wireless charging management chip 223. Since the receiving antenna 221 (e.g., receiving coil) is disposed substantially in the battery area, in order to reduce the heat generated by the receiving antenna 221 (e.g., receiving coil) and ensure the safety of the battery, it is necessary to reduce the heat generated by the receiving antenna 221 (e.g., receiving coil) and reduce the temperature of the receiving antenna 221 (e.g., receiving coil). The method for reducing the heat generation of the receiving antenna 221 (such as a receiving coil) in the embodiment of the present application is to increase the output voltage of the wireless receiving chip, thereby reducing the current. The problem caused by the increase of the output voltage of the wireless receiving chip is that the voltages applied to the input and output terminals of the back-end wireless charging management chip 223 become large, resulting in an increase of heat generation at the back-end. In order to reduce the heat generation at the rear end, the first battery 24 and the second battery 25 are connected in series, so that the voltages at the two ends of the first battery 24 and the second battery 25 after being connected in series are increased, for example, 4.8V is needed at the two ends of the original battery, 9.6V is needed at the two ends of the first battery 24 and the second battery 25 after being connected in series, the voltage difference between the input and the output of the wireless charging management chip 223 is reduced, and the heat generation of the wireless charging management chip 223 is reduced. Meanwhile, the output voltage of the wireless receiving chip can be further increased, the output current of the wireless receiving chip can be reduced, and the heat generation of the receiving antenna 221 and the wireless receiving chip can be reduced. Improving the overall temperature rise of the wireless charging module 22.

When the output terminal of the wired charging module 21 outputs the first charging signal, the battery control circuit 23 connects the third output terminal 235 to the ground, for example, the second output terminal 234 is connected to the ground inside the battery control circuit 23, so as to ground the negative electrode of the first battery 24 connected to the third output terminal 235 of the battery control circuit 23. Meanwhile, the first output terminal 233 and the second output terminal 234 are both communicated with the first input terminal so that the first battery 24 and the second battery 25 connected in parallel with the first battery 24 are connected with the output terminal of the wired charging module 21.

When the output terminal of the wireless charging module 22 outputs the second charging signal and the output terminal of the wired charging module 21 does not output the first charging signal, the battery control circuit 23 connects the second output terminal 234 with the third output terminal 235 to connect the negative electrode of the first battery 24 with the positive electrode of the second battery 25, that is, the first battery 24 and the second battery 25 are connected in series. Meanwhile, the second input terminal 232 is communicated with the first output terminal 233 to realize the connection of the first battery 24 and the second battery 25 connected in series with the first battery 24 with the output terminal of the wireless charging module 22.

It is understood that the electronic device includes two charging modes, namely a wired charging mode and a wireless charging mode. For the wireless charging mode, the problem is that heat is generated at present. The heat generation source mainly comes from three aspects: a receiving antenna (such as a receiving coil), a wireless receiving chip and a wireless charging management chip. Since the receiving antenna (e.g., receiving coil) is located substantially in the battery area, in order to reduce the heat generated by the receiving antenna (e.g., receiving coil) and ensure the safety of the battery, it is necessary to reduce the heat generated by the receiving antenna (e.g., receiving coil) and lower the temperature of the receiving antenna (e.g., receiving coil). The method for reducing the heat generation of the receiving antenna (such as a receiving coil) is to increase the output voltage of the wireless receiving chip, so as to reduce the current. The problem that comes after wireless receiving chip output voltage improves is that the voltage that adds in the wireless management chip input of charging of rear end and output grow, leads to the increase of generating heat of rear end. In order to reduce the heat generation of the rear end, the first battery and the second battery are connected in series, so that the voltages at two ends of the first battery and the second battery after being connected in series are increased, if the voltage at two ends of the original battery needs 4.8V, the voltage at two ends of the first battery and the voltage at two ends of the second battery after being connected in series need 9.6V, the voltage difference of the input and the output of the wireless charging management chip is reduced, and the heat generation of the wireless charging management chip is reduced. Meanwhile, the output voltage of the wireless receiving chip can be further improved, the output current of the wireless receiving chip can be reduced, and the heating of the receiving antenna and the wireless receiving chip can be reduced. Improve wireless charging module's whole temperature rise.
