[0048] The embodiments of the present application provide an electronic device, referring to Figure 1 The electronic device includes a battery pack 1.

[0049] The battery pack 1 includes:

[0050] A first battery cell 11;

[0051] A second battery cell 12;

[0052] A control circuit 13 connected to the first battery cell 11 and the second battery cell 12. The first battery cell 11, the second battery cell 12 and the control circuit 13 are packaged as a battery pack and provide a first positive connection end 14, a second positive connection end 15 and a negative connection end 16.

[0053] The battery pack 1 provides two different voltages through the first positive connection end 14, the second positive connection end 15 and the negative connection end 16; or / and,

[0054] The battery pack 1 provides two same voltages through the first positive connection end 14, the second positive connection end 15 and the negative connection end 16.

[0055] In the embodiments of the present application, the battery pack includes a first battery cell and a second battery cell, which can improve the power supply time of the battery pack. The capacity of the first battery cell can be the same as or different from the capacity of the second battery cell. Preferably, the capacity of the first battery cell is greater than the capacity of the second battery cell. The control circuit is used to connect the first battery cell and the second battery cell to output a voltage to the first positive connection end and the second positive connection end of the battery pack. The voltage of the first battery cell and the second battery cell can be used to make the battery pack provide two same voltages or two different voltages to meet different voltage requirements of external devices. The battery pack can supply power to different components of the same device through the first positive connection end and the second positive connection end, and can also supply power to different devices.

[0056] The electronic device provided by the embodiments of the present application can provide two different voltages or / and the same voltage through the first positive connection end, the second positive connection end and the negative connection end of the battery pack, so as to meet different requirements of external devices, that is, the same external device with two voltage requirements can be powered, and the external device with different voltage requirements can also be powered, without the help of other boost circuits and buck circuits, thereby solving the problem of power loss caused by using boost circuits and buck circuits to meet the requirements of power components in the related art, reducing power loss and prolonging power-on time.

[0057] Based on the foregoing embodiments, the embodiments of the present application provide an electronic device, which comprises a battery pack 1, wherein,

[0058] The battery pack 1 comprises:

[0059] a first battery cell 11;

[0060] a second battery cell 12;

[0061] a control circuit 13 connected with the first battery cell 11 and the second battery cell 12. The first battery cell 11, the second battery cell 12 and the control circuit 13 are packaged as a battery pack and provide a first positive connection end 14, a second positive connection end 15 and a negative connection end 16.

[0062] The battery pack 1 provides two different voltages through the first positive connection end 14, the second positive connection end 15 and the negative connection end 16; or / and,

[0063] The battery pack 1 provides two same voltages through the first positive connection end 14, the second positive connection end 15 and the negative connection end 16.

[0064] The control circuit controls the first battery cell and the second battery cell to be in a first connection mode to provide two different voltages through the first positive connection end, the second positive connection end and the negative connection end; or / and

[0065] The control circuit controls the first battery cell and the second battery cell to be in a second connection mode to provide the same voltage through the first positive connection end, the second positive connection end and the negative connection end.

[0066] As shown in FIG. 1, the first connection mode is: Figure 2

[0067] The positive pole of the first battery cell 11 is connected with the first positive connection end 14, the positive pole of the second battery cell 12 is connected with the negative pole of the first battery cell 11 and the second positive connection end 15, and the negative pole of the second battery cell 12 is connected with the negative connection end 16.

[0068] ​In this embodiment, one end of the voltage of the second battery cell can be directly output to the second positive terminal, and the other end of the voltage of the second battery cell is connected in series with the first battery cell and then output to the first positive terminal. Since the voltage obtained at the first positive terminal is the voltage of the first and second battery cells connected in series, the voltage at the first positive terminal is the sum of the voltages of the first and second battery cells, and the voltage obtained at the second positive terminal is the voltage of the second battery cell. That is, if the voltages of the first and second battery cells are both 4V, then the voltage output to the first positive terminal is 8V, and the voltage output to the second positive terminal is 4V. This allows two different voltages to be provided through the first and second positive terminals. A higher voltage is output through the first positive terminal to meet the voltage supply requirements of devices connected to the first positive terminal with higher voltage demands, and a lower voltage is output through the second positive terminal to meet the voltage supply requirements of devices connected to the second positive terminal with higher voltage demands. This reduces energy consumption and improves energy utilization.

[0069] It should be noted that during normal use, the first and second cells of the battery pack are connected in the first connection mode to meet the different voltage requirements of different components.

[0070] In other embodiments of this application, the second connection method may include a series connection method and a parallel connection method.

[0071] Among them, such as Figure 3 As shown, the series connection method is as follows:

[0072] The positive terminal of the first battery cell 11 is connected to the first positive terminal 14 and the second positive terminal 15, and the negative terminal of the first battery cell 11 is connected to the positive terminal of the second battery cell 12.

[0073] In this embodiment, the first and second battery cells can be connected in series to provide voltage to the first and second positive terminals. In this case, the voltages output by the first and second battery cells flow through the same circuit to provide voltage to the first and second positive terminals, thus ensuring that the voltages at the first and second positive terminals are the same. If the voltages of the first and second battery cells are relatively low, they can be connected in series to provide voltage to the first, second, and negative terminals, thereby increasing the battery pack's power supply time.

[0074] The parallel connection method is as follows:

[0075] The positive terminal of the first battery cell 11 is connected to the first positive terminal 14 and the second positive terminal 15, and the negative terminal of the first battery cell 11 is connected to the negative terminal 16.

[0076] The positive electrode of the second battery cell 12 is connected with the first positive electrode connecting end 14 and the second positive electrode connecting end 15, and the negative electrode of the second battery cell is connected with the negative electrode connecting end 16.

[0077] In the embodiment of the present application, the first battery cell and the second battery cell can provide voltage to the first positive electrode connecting end and the second positive electrode connecting end after being connected in parallel. In this case, the voltage obtained by the first positive electrode connecting end and the second positive electrode connecting end is the same, which can be the average of the sum of the voltage of the first battery cell and the second battery cell. If the voltage of the first battery cell and the second battery cell is relatively small, the parallel connection mode can be used to provide voltage to the first positive electrode connecting end, the second positive electrode connecting end and the negative electrode connecting end, so as to increase the power supply time of the battery pack.

[0078] In other embodiments of the present application, the control circuit controls the connection mode of the first battery cell 11 and the second battery cell 12 based on the voltage of the battery pack 1.

[0079] In the embodiment of the present application, the control circuit is used to control the connection mode of the first battery cell and the second battery cell. After obtaining the voltage of the first battery cell and the second battery cell, the control circuit controls the connection mode of the first battery cell and the second battery cell to be the first connection mode, or the series connection mode, or the parallel connection mode based on the voltage of the first battery cell and the second battery cell.

[0080] In other embodiments of the present application, if the voltage of the battery pack 1 is greater than the threshold value, the control circuit controls the first battery cell 11 and the second battery cell 12 to be in the first connection mode based on the voltage of the battery pack 1.

[0081] If the voltage of the battery pack is less than or equal to the threshold value, the control circuit controls the first battery cell 11 and the second battery cell 12 to be in the second connection mode based on the voltage of the battery pack 1.

[0082] In the embodiment of the present application, the voltage of the battery pack being greater than the threshold value means that the voltage of the first battery cell and the second battery cell is greater than the threshold value; the voltage of the battery pack being less than or equal to the threshold value can mean that the voltage of the first battery cell and the second battery cell is less than or equal to the threshold value, or the voltage of the first battery cell is less than the threshold value, or the voltage of the second battery cell is less than the threshold value, or the voltage of the first battery cell and the second battery cell is less than the threshold value, which is not limited in the embodiment of the present application. The threshold value can be a pre-set threshold value for measuring whether the first battery cell and the second battery cell reach low voltage. Generally, the voltage of the battery cell is between 3.2V and 4.4V, and preferably, the threshold value can be set to 3.5V. If the voltage of the battery pack is greater than 3.5V, the control circuit controls the connection mode of the first battery cell and the second battery cell to be the first connection mode. If the voltage of the battery pack is less than or equal to 3.5V, the control circuit controls the connection mode of the first battery cell and the second battery cell to be the second connection mode.

[0083] In other embodiments of the present application, if the voltage of the first battery cell 11 and / or the voltage of the second battery cell 12 is less than or equal to the threshold value, and the voltage of the first battery cell 11 is different from the voltage of the second battery cell 12, the control circuit controls the first battery cell 11 and the second battery cell 12 to be connected in series to provide two same voltages through the first positive connection end 14, the second positive connection end 15 and the negative connection end 16; or,

[0084] If the voltage of the first battery cell 11 and / or the voltage of the second battery cell 12 is less than or equal to the threshold value, and the voltage of the first battery cell 11 is the same as the voltage of the second battery cell 12, the control circuit controls the first battery cell 11 and the second battery cell 12 to be connected in parallel or in series to provide two same voltages through the first positive connection end 14, the second positive connection end 15 and the negative connection end 16.

[0085] In embodiments of the present application, when the first battery cell and the second battery cell normally provide voltages to the first positive connection end, the second positive connection end and the negative connection end to supply power to external devices, the voltages of the first battery cell and the second battery cell will decrease over time, and the voltages of the first battery cell and the second battery cell will be different due to circuit, hardware and device reasons. In this case, if the connection mode of the first battery cell and the second battery cell is directly switched to the parallel connection mode, it will cause the battery pack to fail. In this case, when the voltages of the first battery cell and the second battery cell are less than or equal to the threshold value, and the voltages of the first battery cell and the second battery cell are different, there are two possible processing methods as follows:

[0086] In one possible processing method, the connection mode of the first battery cell and the second battery cell can be directly switched from the first connection mode to the series connection mode. When the first battery cell and the second battery cell are connected in series, the voltage difference between the first battery cell and the second battery cell will gradually decrease over time, so that the first battery cell and the second battery cell can reach the same low voltage. In this case, the control circuit can continue to maintain the current connection mode of the first battery cell and the second battery cell, or control the first battery cell and the second battery cell to be connected in parallel to increase the power supply time of the battery pack to the external device and ensure the normal operation of the external device.

[0087] In another possible processing method, the connection between the battery cell with higher voltage and the first positive connection end and the second positive connection end can be first cut off, that is, the battery cell with higher voltage is used to provide voltages to the first positive connection end, the second positive connection end and the negative connection end. In the case that the voltages of the first battery cell and the second battery cell are the same, the control circuit can control the first battery cell and the second battery cell to be connected in series or in parallel to increase the power supply time of the battery pack to the external device and ensure the normal operation of the external device.

[0088] In other embodiments of the application, as shown in Figure 5 The control circuit 13 further includes:

[0089] The first switch 131 has an input end connected with the positive pole of the first battery cell 11 and a first output end of the second switch 132, and an output end connected with the second positive pole connecting end 15.

[0090] The second switch 132 has an input end connected with the positive pole of the second battery cell 12, and a second output end connected with the negative pole of the first battery cell 11.

[0091] The third switch 133 has an input end connected with the positive pole of the second battery cell 12, and an output end connected with the second positive pole connecting end 15.

[0092] The fourth switch 134 has an input end connected with the negative pole connecting end 16, and an output end connected with the negative pole of the first battery cell 11.

[0093] In the embodiments of the application, the control circuit can switch the connection mode between the first battery cell and the second battery cell through the first switch, the second switch, the third switch and the fourth switch, that is, switch the connection mode between the first battery cell and the second battery cell between the first connection mode, the series connection mode and the parallel connection mode through the first switch, the second switch, the third switch and the fourth switch.

[0094] In other embodiments of the application, as shown in Figure 6 The control circuit 13 further includes:

[0095] The first measurement module 135 has an input end connected with the output end of the fourth switch 134, a first output end connected with the negative pole of the first battery cell 11, and is configured to detect the voltage of the first battery cell 11.

[0097] In the embodiments of the present application, the first measuring module and the second measuring module can be voltage measuring instruments. The voltage of the first battery cell can be obtained by the first measuring module, and the voltage of the second battery cell can be obtained by the second measuring module. Thus, the control circuit can obtain the voltage of the first battery cell and the voltage of the second battery cell, and control the connection mode between the first battery cell and the second battery cell to switch between the first connection mode, the series connection mode and the parallel connection mode based on the voltage of the first battery cell and the voltage of the second battery cell, so as to cope with different circuit conditions.

[0100] The control module 137 is configured to, in the case that the first battery cell 11 and the second battery cell 12 are in the first connection mode, control the input end of the second switch 132 to be in communication with the second output end of the second switch 132, and the third switch 133 to be in communication, and the first switch 131 and the fourth switch 134 to be turned off;

[0101] The control module 137 is further configured to, in the case that the first battery cell 11 and the second battery cell 12 are in the series connection mode, control the input end of the second switch 132 to be in communication with the second output end of the second switch 132, and the first switch 131 to be in communication, and the third switch 133 and the fourth switch 134 to be turned off;

[0102] The control module 137 is further configured to, in the case that the first battery cell 11 and the second battery cell 12 are in the parallel connection mode, control the input end of the second switch 132 to be in communication with the first output end of the second switch 132, and the first switch 131 and the fourth switch 134 to be in communication, and the third switch 133 to be turned off.

[0103] In the embodiments of the present application, the control module can be a microcontroller unit (MCU). The control module can control the communication and / or turn-off of the first switch, the second switch, the third switch and the fourth switch based on the voltage value measured by the first measuring module and the voltage value measured by the second measuring module, so as to switch the connection mode between the first battery cell and the second battery cell between the first connection mode, the series connection mode and the parallel connection mode, so as to cope with different circuit conditions.

[0109] The negative electrode of the second battery cell 12 is connected to the negative connection end 16.

[0110] In the embodiments of the present application, the target voltage can be pre-set, and the target voltage is used to determine whether the external charging device is high voltage or low voltage. For example, it can be set to 4V, and in the case where the voltage of the external charging device is greater than 5V, it is considered that the external charging device is high voltage, and in this case, the target connection mode of the first battery cell and the second battery cell is that the positive electrode of the first battery cell is connected to the first positive connection end, the negative electrode of the first battery cell is connected to the positive electrode of the second battery cell, and the negative electrode of the second battery cell is connected to the negative connection end, that is, the first battery cell and the second battery cell are connected in series.
