[0052] Figure 10 This is a block diagram illustrating an electronic device according to an exemplary embodiment. Detailed Implementation

[0053] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0054] Figure 1 This is a schematic diagram of a power supply circuit according to an exemplary embodiment, such as... Figure 1As shown, the power supply circuit includes: a controller 101, a battery module 102, a first switch assembly 1031, a first power consumption module 104, and a second power consumption module 105. The battery module 102 includes a first battery module 1021, a second battery module 1022, and a third battery module 1023. The first battery module 1021 is connected to the first power consumption module 104, the second battery module 1022 is connected in series with the third battery module 1023 through the first switch assembly 1031, and the third battery module 1023 is connected to the second power consumption module 105.

[0055] The controller 101 is connected to the first battery module 1021, the second battery module 1022, the third battery module 1023, and the first switch assembly 1031, respectively. It is used to acquire the first charge level of the first battery module 1021, the second charge level of the second battery module 1022, and the third charge level of the third battery module 1023. When it is determined that the first charge level, the second charge level, and the third charge level are all greater than or equal to a preset charge threshold, it controls the first switch assembly 1031 to close and controls the first battery module 1021 to supply power to the first power consumption module 104, while the second battery module 1022 and the third battery module 1023 jointly supply power to the second power consumption module 105.

[0056] The controller 101 can be a platform chip for a smart terminal device such as a mobile phone or tablet. The platform chip can include a central processing unit, an image processor, a memory controller, and a storage controller, etc., and can handle tasks such as computing, storage, and communication, as well as control and manage various functional modules of the smart terminal device. The first power module 104 can be the platform chip and the audio part of the smart terminal device. The audio part can handle tasks such as input, output, decoding, and amplification of sound signals. The second power module 105 can be the screen of the smart terminal device. The first switch component 1031 can be a P-type MOSFET or an N-type MOSFET. The battery module 102 can include multiple battery cells for storing or releasing electrical energy. The battery module 102 can also include a battery management system for monitoring parameters such as voltage, current, and temperature of the first battery module 1021, the second battery module 1022, and the third battery module 1023, and can also provide a communication interface to interact with the controller 101.

[0057] It should be noted that the power of the second power module 105 is fixed. When the first power, the second power, and the third power are all greater than or equal to the preset power threshold, the second power module 105 can be powered by the second battery module 1022 and the third battery module 1023. Increasing the supply voltage of the second power module 105 reduces the supply current, thereby reducing current consumption and power consumption.

[0058] For example, Figure 2 This is a schematic diagram of a screen power supply circuit according to an exemplary embodiment, such as... Figure 2 As shown, the second power module is the screen, and the screen's power is 5000mW. With a default power supply, the default power supply is connected to the drive inductor L6408 via the power pin VPH_PWR to power the screen. The default power supply provides a voltage of 4V, and the efficiency of powering the screen via the default power supply is 85%. With a battery power supply, the battery power supply is connected to the drive inductor L6408 via the power pin VBATT to power the screen. The battery power supply is provided by the second and third battery modules connected in series. The battery power supply provides a voltage of up to 8V, and the efficiency of powering the screen via the battery power supply is 92%. The default power supply for the screen can be changed to the battery power supply to increase the screen's supply voltage, thereby reducing the supply current and minimizing power loss.

[0059] The above technical solution, by controlling the second battery module and the third battery module to jointly supply power to the second power module, can increase the voltage to reduce current consumption and power consumption, thereby improving the battery's range and effectively enhancing the user experience and satisfaction.

[0060] Figure 3 It is based on Figure 1 The illustrated embodiment shows a schematic diagram of a power supply circuit, as shown below. Figure 3 As shown, the power supply circuit also includes a second switch assembly 1032, and the second battery module 1022 is connected to the first power consumption module 104 through the second switch assembly 1032;

[0061] The controller 101 is also connected to the second switch assembly and is used to control the first switch assembly to open and the second switch assembly to close when the first power level is determined to be less than or equal to a preset first power level threshold, and to control the second battery module 1022 to supply power to the first power module 104.

[0062] The second switching component 1032 can be a P-type MOSFET or an N-type MOSFET. When the first switching component 1031 is open, the second battery module 1022 and the third battery module 1023 switch to a parallel state, and can supply power to the first power module 104 and the second power module 105 by increasing the current.

[0063] It should be noted that when the first power level is less than or equal to a preset first power threshold, the first battery module 1021 automatically cuts off power and no longer supplies power to the first power-consuming module 104. At this time, the second battery module supplies power to the first power-consuming module through the second switching assembly, and the third battery module supplies power to the second power-consuming module.

[0064] The above technical solution, when the first battery module is powered off, adds a path for the second battery module to supply power to the first power-consuming module through the second switching component, which helps to improve the reliability of the power supply circuit.

[0065] Figure 4 It is based on Figure 3 The illustrated embodiment shows a schematic diagram of a power supply circuit, as shown below. Figure 4 As shown, the power supply circuit also includes a third switch assembly 1033, and the third battery module 1023 is connected to the first power consumption module 104 through the third switch assembly 1033;

[0066] The controller 101 is also connected to the third switch assembly 1033, and is used to control the first switch assembly 1031 to open and the third switch assembly 1033 to close when the first power is determined to be less than or equal to a preset first power threshold, and to control the third battery module 1023 to supply power to the first power module 104.

[0067] The third switching component 1033 can be either a P-type MOSFET or an N-type MOSFET.

[0068] It should be noted that when the first power level is less than or equal to a preset first power level threshold, the first switch component can be controlled to open and the third switch component can be controlled to close. The third battery module can supply power to the first power module and also supply power to the second power module through the third switch component.

[0069] The above technical solution, when the first battery module is powered off, adds a path for the third battery module to supply power to the first power-consuming module through the third switching component, which helps to improve the reliability of the power supply circuit.

[0070] Figure 5 It is based on Figure 3 The illustrated embodiment shows a schematic diagram of another power supply circuit, as shown below. Figure 5 As shown, the power supply circuit also includes a fourth switch assembly 1034, and the second battery module 1022 is connected to the second power consumption module 105 through the fourth switch assembly 1034;

[0071] The controller 101 is also connected to the fourth switch assembly 1034 and is used to control the first switch assembly 1031 to open and the second switch assembly 1032 and the fourth switch assembly 1034 to close when the first power is determined to be less than or equal to a preset first power threshold, and to control the second battery module 1022 to supply power to the first power module 104 and the second power module 105.

[0072] The fourth switching component 1034 can be either a P-type MOSFET or an N-type MOSFET.

[0073] It should be noted that when the second battery module supplies power to the first power module and the second power module, the first switch assembly, the third switch assembly, and the fifth switch assembly are disconnected, and the second switch assembly and the fourth switch assembly are closed. The second battery module can supply power to the first power module through the second switch assembly, and the second battery module can also supply power to the second power module through the fourth switch assembly.

[0074] The above technical solution, when the first battery module is powered off, adds a path for the second battery module to simultaneously supply power to the first and second power modules through the second and fourth switch components, which helps to improve the reliability of the power supply circuit.

[0075] Figure 6 It is based on Figure 1 The illustrated embodiment shows a schematic diagram of another power supply circuit, as shown below. Figure 6 As shown, the power supply circuit also includes a fifth switch assembly 1035, and the second battery module 1022 is connected to the second power consumption module 105 through the fifth switch assembly 1035;

[0076] The controller 101 is further configured to control the fifth switch assembly 1035 to close and control the first battery module 1021 to supply power to the second power module 105 when it is determined that the second power level is less than a preset second power level threshold or the third power level is less than a preset third power level threshold.

[0077] The fifth switching component 1035 can be either a P-type MOSFET or an N-type MOSFET.

[0078] It should be noted that the second and third battery modules are connected in series, allowing simultaneous consumption of power from both modules. However, differences in power levels between the batteries may exist, resulting in situations where the second power level is less than a preset second power threshold or the third power level is less than a preset third power threshold. If either the second or third power level is determined to be less than the preset second power threshold or the third power level is less than the preset third power threshold, the first battery module can supply power to the second power-consuming module via the fifth switching assembly, and the first battery module can also supply power to the first power-consuming module.

[0079] The above technical solution, when the second or third battery module is powered off, adds a path for the first battery module to supply power to the second power module through the fifth switch assembly, which helps to improve the reliability of the power supply circuit.

[0080] Optionally, the controller 101 is further configured to obtain a target difference between the second power level and the third power level, and if the target difference is greater than or equal to a preset deviation value, and if it is determined that the first switch assembly 1031 is open, then control the first switch assembly 1031 to close.

[0081] The target difference is the absolute value of the difference between the second power level and the third power level.

[0082] It should be noted that the first switch assembly is in the closed state by default, and the second and third battery modules are connected in series. However, when designing different second and third battery modules, a master battery and a slave battery are determined. With a master and slave battery, the master battery's power is consumed first, resulting in a power deviation between the second and third battery modules. Therefore, if the target difference is greater than or equal to a preset deviation value, the first switch assembly needs to be closed again to ensure that the power of both the second and third battery modules can be consumed simultaneously.

[0083] The above technical solution, when the target difference is greater than or equal to the preset deviation value, controls the first switch component to close, which can ensure that the power of the second battery module and the third battery module are consumed at the same time, thereby avoiding the phenomenon of power fluctuation.

[0084] Figure 7 It is based on Figure 1 The illustrated embodiment shows a schematic diagram of another power supply circuit, such as... Figure 7 As shown, the power supply circuit also includes a second switch assembly 1032, a third switch assembly 1033, a fourth switch assembly 1034, and a fifth switch assembly 1035;

[0085] When it is determined that the first power level, the second power level, and the third power level are all greater than or equal to a preset power threshold, the first switch assembly 1031 is closed, the second switch assembly 1032, the third switch assembly 1033, the fourth switch assembly 1034, and the fifth switch assembly 1035 are opened, the first battery module 1021 supplies power to the first power consumption module 104, and the second battery module 1022 and the third battery module 1023 supply power to the second power consumption module 105.

[0086] When the first power level is determined to be less than or equal to a preset first power level threshold, the second switch assembly 1032 is closed, and the first switch assembly 1031, the third switch assembly 1033, the fourth switch assembly 1034 and the fifth switch assembly 1035 are opened. The second battery module 1022 supplies power to the first power module 104 through the second switch assembly 1032, and the third battery module 1023 supplies power to the second power module 105.

[0087] When the first power level is determined to be less than or equal to a preset first power level threshold, the third switch assembly 1033 is closed, and the first switch assembly 1031, the second switch assembly 1032, the fourth switch assembly 1034 and the fifth switch assembly 1035 are opened. The third battery module 1023 supplies power to the first power module 104 through the third switch assembly 1033, and at the same time, the third battery module 1023 supplies power to the second power module 105.

[0088] When the first power level is determined to be less than or equal to a preset first power level threshold, the second switch assembly 1032 and the fourth switch assembly 1034 are closed, and the first switch assembly 1031, the third switch assembly 1033 and the fifth switch assembly 1035 are opened. The second battery module 1022 supplies power to the first power consumption module 104 through the second switch assembly 1032, and at the same time, the second battery module 1022 supplies power to the second power consumption module 105 through the fourth switch assembly 1034.

[0089] When it is determined that the second power level is less than a preset second power level threshold or the third power level is less than a preset third power level threshold, the fifth switch assembly 1035 is closed, and the first switch assembly 1031, the second switch assembly 1032, the third switch assembly 1033, and the fourth switch assembly 1034 are disconnected. The first battery module 1021 supplies power to the second power consumption module 105 through the fifth switch assembly 1035, and at the same time, the first battery module 1021 supplies power to the first power consumption module 104.

[0090] The above technical solution, where the second and third battery modules jointly power the second power-consuming module, increases the supply voltage to reduce current consumption, thereby reducing power consumption, improving battery life, and ultimately enhancing user experience and satisfaction. Furthermore, in the event that the first, second, or third battery module is powered off, providing multiple power supply pathways to the first and second power-consuming modules improves the reliability of the power supply circuit.

[0091] Figure 8 This is a flowchart illustrating a power supply method according to an exemplary embodiment, such as... Figure 8 As shown, this power supply method can be applied to a preset power supply circuit, which can be one of the above-mentioned power supply circuits. Figure 1 or Figures 3 to 7 The power supply circuit in any one of the following embodiments, wherein the preset power supply circuit comprises: a battery module, a first switch assembly, a first power consumption module and a second power consumption module, the battery module comprising a first battery module, a second battery module and a third battery module; the first battery module is connected to the first power consumption module, the second battery module is connected in series with the third battery module through the first switch assembly, and the third battery module is connected to the second power consumption module;

[0092] The power supply method may include the following steps:

[0093] Step 801: Obtain the first battery level of the first battery module, the second battery level of the second battery module, and the third battery level of the third battery module.

[0094] The controller can be a platform chip of a smart terminal device, which may include a central processing unit, an image processor, a memory controller, and a storage controller, etc., and can handle tasks such as computing, storage, and communication, as well as control and manage various functional modules of the smart terminal device; the first power module can be the platform chip and the audio part of the smart terminal device, which can handle tasks such as input, output, decoding, and amplification of sound signals; the second power module can be the screen of the smart terminal device, and the first switching component can be a P-type MOSFET or an N-type MOSFET; the battery module can monitor parameters such as voltage, current, and temperature of the first battery module, the second battery module, and the third battery module, and can also provide a communication interface to interact with the controller.

[0095] In this step, the controller can interact with the battery module to obtain the first battery module's first charge level, the second battery module's second charge level, and the third battery module's third charge level.

[0096] Step 802: When it is determined that the first power level of the first battery module, the second power level of the second battery module, and the third power level of the third battery module are all greater than or equal to a preset power threshold, the first switch assembly is controlled to close, and the first battery module is controlled to supply power to the first power-consuming module, while the second battery module and the third battery module jointly supply power to the second power-consuming module.

[0097] The above technical solution, by controlling the second battery module and the third battery module to jointly supply power to the second power module, can increase the supply voltage to reduce current consumption, thereby reducing power consumption, improving battery life, and thus effectively improving user experience and satisfaction.

[0098] Optionally, the preset power supply circuit further includes: a second switching assembly, wherein the second battery module is connected to the first power-consuming module through the second switching assembly;

[0099] The power supply method further includes:

[0100] If the first power level is determined to be less than or equal to a preset first power level threshold, the first switch assembly is controlled to open, the second switch assembly is controlled to close, and the second battery module is controlled to supply power to the first power module.

[0101] The second switching component can be either a P-type MOSFET or an N-type MOSFET.

[0102] In this step, when the first battery level is less than or equal to a preset first battery level threshold, the first battery module automatically cuts off power and stops supplying power to the first power-consuming module. At this time, the second battery module supplies power to the first power-consuming module through the second switching component, and the third battery module supplies power to the second power-consuming module.

[0103] The above technical solution, when the first battery module is powered off, adds a path for the second battery module to supply power to the first power-consuming module through the second switching component, which helps to improve the reliability of the power supply circuit.

[0104] Optionally, the preset power supply circuit further includes: a third switch assembly, through which the third battery module is connected to the first power consumption module;

[0105] The power supply method further includes:

[0106] If the first power level is determined to be less than or equal to a preset first power level threshold, the first switch assembly is controlled to open, the third switch assembly is controlled to close, and the third battery module is controlled to supply power to the first power consumption module.

[0107] The third switching component can be either a P-type MOSFET or an N-type MOSFET.

[0108] In this step, when the first power level is less than or equal to a preset first power level threshold, the third battery module can supply power to the first power module and also supply power to the second power module through the third switch component.

[0109] The above technical solution, when the first battery module is powered off, adds a path for the third battery module to supply power to the first power-consuming module through the third switching component, which helps to improve the reliability of the power supply circuit.

[0110] Optionally, the preset power supply circuit further includes: a fourth switch assembly, through which the second battery module is connected to the second power consumption module;

[0111] The power supply method further includes:

[0112] If the first power level is determined to be less than or equal to a preset first power level threshold, the first switch assembly is controlled to open, the second switch assembly and the fourth switch assembly are controlled to close, and the second battery module is controlled to supply power to the first power module and the second power module.

[0113] The fourth switching component 1034 can be either a P-type MOSFET or an N-type MOSFET.

[0114] In this step, the second battery module can supply power to the first power module through the second switch assembly, and the second battery module can also supply power to the second power module through the fourth switch assembly.

[0115] The above technical solution, when the first battery module is powered off, adds a path for the second battery module to simultaneously supply power to the first and second power modules through the second and fourth switch components, which helps to improve the reliability of the power supply circuit.

[0116] Optionally, the preset power supply circuit further includes: a fifth switch assembly, through which the first battery module is connected to the second power consumption module;

[0117] The power supply method further includes:

[0118] If it is determined that the second power level is less than a preset second power level threshold or the third power level is less than a preset third power level threshold, the fifth switch assembly is controlled to close, and the first battery module is controlled to supply power to the second power module.

[0119] The fifth switching component 1035 can be either a P-type MOSFET or an N-type MOSFET.

[0120] In this step, the first battery module can supply power to the second power module through the fifth switch assembly, and the first battery module can also supply power to the first power module.

[0121] The above technical solution, when the second or third battery module is powered off, adds a path for the first battery module to supply power to the second power module through the fifth switch assembly, which helps to improve the reliability of the power supply circuit.

[0122] Figure 9 It is based on Figure 8 The illustrated embodiment shows a flowchart of a power supply method, such as... Figure 9 As shown, the power supply method includes:

[0123] Step S11: Obtain the target difference between the second power level and the third power level.

[0124] The target difference is the absolute value of the difference between the second power level and the third power level.

[0125] Step S12: If the target difference is greater than or equal to the preset deviation value, and it is determined that the first switch component is open, then the first switch component is controlled to close.

[0126] In this step, the first switch assembly is in the closed state by default, and the second and third battery modules are connected in series. However, when designing different second and third battery modules, a master battery and a slave battery are determined. With a master and slave battery, the master battery's power is consumed first, resulting in a power deviation between the second and third battery modules. Therefore, if the target difference is greater than or equal to a preset deviation value, the first switch assembly needs to be closed again to ensure that the power of both the second and third battery modules can be consumed simultaneously.

[0127] The above technical solution, when the target difference is greater than or equal to the preset deviation value, controls the first switch component to close, which can ensure that the power of the second battery module and the third battery module are consumed at the same time, thereby avoiding the phenomenon of power fluctuation.
