Description

Technical Field

[0001] This disclosure relates to the field of battery power supply technology, and in particular to a method, apparatus, device and computer-readable storage medium for determining a battery power supply mode. Background Technology

[0002] Figure 1 This is a schematic diagram of a structure including a battery-powered circuit according to an embodiment of the present disclosure.

[0003] like Figure 1 As shown, some batteries or battery packs have a high voltage, which needs to be converted to a low voltage by the battery power supply circuit before it can supply power to the load circuit.

[0004] In related technologies, a voltage detection module can be added to the battery power supply circuit to determine the power supply mode by detecting the battery voltage.

[0005] However, this method requires adding a voltage detection module, which involves hardware modifications and is quite cumbersome. Furthermore, the battery output voltage changes depending on the load. For example, during tasks such as taking photos or running games, the current fluctuates significantly, leading to corresponding voltage fluctuations and causing the power supply mode to switch repeatedly, resulting in poor stability. Summary of the Invention

[0006] To overcome the problems existing in the related technologies, this disclosure provides a method, apparatus, device and computer-readable storage medium for determining a battery power supply mode, which can solve the above problems.

[0007] According to a first aspect of the present disclosure, a method for determining a battery-powered mode is provided, the method comprising:

[0008] Determine the current charge level of the battery;

[0009] The power supply mode of the battery is determined under preset conditions; wherein,

[0010] The preset conditions include: the current power value is within the range of the corresponding power supply mode.

[0011] According to a second aspect of the present disclosure, a device for determining a battery-powered mode is provided, the device comprising:

[0012] A power determination unit is configured to determine the current power level of the battery;

[0013] The mode determination unit is configured to determine the power supply mode of the battery under preset conditions; wherein the preset conditions include: the current power level is within the range of the corresponding power supply mode.

[0014] According to a third aspect of the present disclosure, an electronic device is provided, comprising: a processor and a memory;

[0015] The memory is used to store computer programs;

[0016] The processor is configured to execute the method for determining the battery power supply mode as described in the first aspect by invoking the computer program.

[0017] According to a fourth aspect of the present disclosure, a computer-readable storage medium is provided having a computer program stored thereon that, when executed by a processor, implements the method for determining a battery-powered mode as described in the first aspect.

[0018] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0019] This disclosure allows for the determination of the battery's current charge level and, based on this charge level, the determination of the battery's power supply mode. Firstly, most terminals already possess a battery charge level sensor, eliminating the need for additional detection circuitry in the hardware, resulting in lower implementation costs and a simpler solution. Secondly, unlike voltage, battery charge changes continuously and slowly, without fluctuations with load, thus preventing the power supply mode from repeatedly switching due to load within a short period, resulting in greater stability.

Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0031] To address the aforementioned technical problems, this disclosure proposes a method for determining a battery-powered mode.

[0032] Figure 2 This is a system architecture diagram illustrating a method for determining a battery power supply mode according to embodiments of the present disclosure.

[0033] like Figure 2 As shown, the system includes:

[0034] The processor 210 is used to execute the method for determining the battery power supply mode proposed in this disclosure. After determining the battery power supply mode, it sends a control signal to the battery power supply circuit 220 to instruct the battery power supply circuit to use the corresponding power supply mode to supply power to the load circuit 230.

[0035] The battery power supply circuit 220 has its controlled end connected to the processor 210, its input end connected to the battery 240, and its output end connected to the load circuit 230. It is used to convert the higher voltage input from the battery 240 into a lower voltage and output it to the load circuit 230.

[0036] Load circuit 230 is used for load;

[0037] Battery 240 is used to provide electrical energy and outputs a higher voltage to the battery power supply circuit. It should be noted that this disclosure does not limit the form of battery 240. Typically, the circuit of battery 240 includes a power sensor, and processor 210 can determine the power level of battery 240 based on the power sensor.

[0038] Figure 3 This is a schematic flowchart illustrating a method for determining a battery power supply mode according to an embodiment of the present disclosure. The method for determining the battery power supply mode can be executed by a processor 210 in a terminal. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and Internet of Things devices.

[0039] like Figure 3 As shown, the method for determining the battery power supply mode includes:

[0040] In step S301, the current charge level of the battery is determined;

[0041] In step S302, the power supply mode of the battery is determined under the condition that the preset conditions are met; wherein the preset conditions include: the current power value is within the range of the corresponding power supply mode.

[0042] In some embodiments, the battery includes a battery pack.

[0043] The battery pack can be connected in series or in parallel.

[0044] In some embodiments, the current battery charge level can be obtained by detecting the battery charge level using a battery power meter.

[0045] Since the terminal needs to display the battery level, most terminals have a battery level detector. Therefore, the method proposed in this disclosure does not require adding an extra detection module to the power supply circuit to determine the current battery level; it can directly use the existing battery level detector.

[0046] In some embodiments, the power sensor can detect the current battery level and send the detected current battery level to the processor.

[0047] The processor determines the current battery charge level using a power sensor.

[0048] In some embodiments, the processor can read information from the battery sensor via a communication interface to determine the current battery charge level.

[0049] In some embodiments, the current charge level of the battery may increase or decrease as the battery is charged or discharged.

[0050] It should be noted that the increase or decrease in the current battery level will not fluctuate significantly with changes in the load of the load circuit 230. The current battery level reflects the electrical energy currently stored in the battery. Compared to changes in battery voltage, changes in the battery level are continuous and slow, and generally do not fluctuate.

[0051] In some embodiments, the power supply mode of the battery is determined when preset conditions are met.

[0052] The processor can preset the correspondence between power supply modes and preset conditions. When the preset conditions are met, the battery power supply circuit will determine to use the corresponding power supply mode.

[0053] In some embodiments, the preset conditions include: the current power value is within the range of the corresponding power supply mode.

[0054] The power supply mode is determined based on the current battery level. Depending on the current battery level's range, the corresponding power supply mode for that range is selected.

[0055] For example, when the current battery level is greater than the first threshold, the first power supply mode can be selected; when the current battery level is not greater than the first threshold, the second power supply mode can be selected; it is also possible to preset the third power supply mode to be used when the current battery level is between the first and second thresholds.

[0056] Compared to related technologies that determine the power supply mode of the battery power supply circuit by detecting the battery voltage, this disclosure does not require adding a new detection module for detecting battery voltage in the circuit. Instead, it determines the power supply mode based on the existing battery level sensor in the circuit and the current battery level. On the one hand, not adding a detection module means that this solution has lower implementation costs and is simpler and more convenient. On the other hand, determining the power supply mode based on the battery level rather than the voltage avoids voltage fluctuations caused by load circuit fluctuations, which would lead to frequent switching of the power supply mode, resulting in higher stability.

[0057] In some embodiments, the power supply modes include charge pump mode and BUCK mode.

[0058] In charge pump mode, the voltage output by the battery-powered circuit is half of the input voltage. Compared to BUCK mode, charge pump mode has no inductor and less energy loss during voltage reduction, resulting in higher efficiency.

[0059] For example, if the battery uses a series battery pack that can provide 8V, while the load circuit hardware is matched to 4V, then a charge pump mode can be used to step down the voltage to power the load circuit.

[0060] However, as the battery is used, its charge will decrease, which will reduce the battery's output voltage. At this time, the charge pump's buck mode may not be able to meet the voltage requirements of the load circuit. In this case, the BUCK mode can be used to reduce the voltage.

[0061] For example, as the battery is used, its output voltage drops from 8V to 6V. If the charge pump mode is still used, the voltage drop will be half the input voltage, resulting in an output voltage of only 3V, which cannot meet the 4V voltage requirement of the load circuit. In this case, the BUCK mode can be used to meet the voltage requirement of the load circuit. The BUCK mode has an inductor, resulting in a smaller voltage drop, but it consumes more energy during the voltage reduction process, thus its conversion efficiency is lower than that of the charge pump mode.

[0062] In some embodiments, the battery-powered circuit can use charge pump mode for step-down or switch to BUCK mode for step-down.

[0063] The battery power supply circuit can be a coupled circuit of charge pump step-down circuit and BUCK step-down circuit. The specific circuit connection method will be described in detail later.

[0064] In some embodiments, determining the power supply mode of the battery under preset conditions includes: determining the power supply mode of the battery as charge pump mode when the current power level is higher than a first threshold; and determining the power supply mode of the battery as BUCK mode when the current power level is lower than the first threshold.

[0065] Using a first threshold, the battery level is divided into two ranges. When the current battery level is higher than the first threshold, a charge pump mode is used, which is highly efficient and has low power loss. When the current battery level is lower than the first threshold, a BUCK mode is used, which can still meet the voltage requirements of the load circuit even when the battery voltage drops.

[0066] In some embodiments, determining the power supply mode of the battery under preset conditions includes: determining the power supply mode of the battery as charge pump mode when the current power level is higher than a first threshold; and determining the power supply mode of the battery as BUCK mode when the current power level is lower than a second threshold.

[0067] If, as in the previous embodiment, only the first threshold is used to divide the two intervals, the current battery level may fluctuate around the first threshold during the alternating charging and discharging operation of the battery. In this case, the power supply mode may switch back and forth.

[0068] To avoid this situation, different threshold values ​​can be set between the first and second thresholds to prevent repeated switching of battery-powered modes.

[0069] In some embodiments, when the first threshold is lower than the second threshold, the priority order of charge pump mode and BUCK mode can be set, and when the current power value is higher than the first threshold and lower than the second threshold, the power supply mode can be determined based on the priority order.

[0070] If the first threshold is lower than the second threshold, the interval corresponding to the charge pump mode and the interval corresponding to the BUCK mode partially overlap. Therefore, a priority order can be set to determine the power supply mode in the overlapping interval.

[0071] In some embodiments, the first threshold is not lower than the second threshold.

[0072] If the first threshold is not lower than the second threshold, frequent switching of power supply mode caused by short-term power fluctuations can be avoided.

[0073] It should be noted that the processor can determine the battery power supply mode as charge pump mode when the current battery level is higher than the first threshold, so that the battery power supply circuit maintains charge pump mode as long as the current battery level is higher than the first threshold; or it can determine the power supply mode as charge pump mode when the current battery level is higher than the first threshold and send a signal to switch the battery power supply circuit to charge pump mode.

[0074] In some embodiments, the battery-powered circuitry continues to use the previously used power supply mode until it receives an instruction from the processor.

[0075] The battery-powered circuit can continue to use the previously used power supply mode until the processor instructs the battery-powered circuit to use a power supply mode determined by the processor through the method presented in this disclosure.

[0076] In some embodiments, the preset conditions further include: when the current battery level is higher than a first threshold, the battery is in a charging state; or when the current battery level is lower than a second threshold, the battery is in a discharging state; wherein, when the current battery level is higher than the first threshold and the battery is in a charging state, the system switches to the charge pump mode for power supply; and when the current battery level is lower than the second threshold and the battery is in a discharging state, the system switches to the BUCK mode for power supply.

[0077] When the battery is charging, the current charge level will continuously increase. When the current charge level is higher than a first threshold, the processor can send a signal to the battery power supply circuit to indicate switching to charge pump mode for power supply. When the battery is discharging, the current charge level will continuously decrease. When the current charge level decreases to below a second threshold, it indicates switching to BUCK mode for power supply.

[0078] In this embodiment, if the first threshold is higher than the second threshold, it can effectively prevent the battery from repeatedly switching power supply modes due to the switching of charging and discharging states.

[0079] For example, the first threshold is 6%, and the second threshold is 5%. When the battery is discharging, it uses charge pump mode to supply power until it reaches 5%. After reaching 5%, it switches to BUCK mode. If the charger is connected at this time, the battery is charging, and the current charge level slowly increases. Even if the current charge level is greater than 5%, it still uses BUCK mode because it has not yet reached 6%. It only switches to charge pump mode after reaching 6%. If the charger is disconnected after switching to charge pump mode and the battery enters a discharging state, it will still run in charge pump mode for a period of time until the current charge level drops below 5% in the discharging state before switching back to charge pump mode.

[0080] Figure 4 This is a schematic diagram of a battery-powered circuit according to an embodiment of the present disclosure.

[0081] like Figure 4 As shown, in the battery power supply circuit 220, the controller is used to receive signals from the processor and control the conduction and disconnection of each MOSFET according to the power supply mode indicated by the processor, thereby realizing different power supply modes.

[0082] The battery power supply circuit disclosed herein is actually formed by coupling a charge pump circuit for implementing the charge pump power supply mode with a BUCK circuit for implementing the BUCK mode.

[0083] In some embodiments, the charge pump mode is implemented based on a charge pump circuit, which includes a first MOSFET Q1, a second MOSFET Q2, a third MOSFET Q3, and a fourth MOSFET Q4. The BUCK mode is executed in the following manner: either the first MOSFET Q1 or the second MOSFET Q2 is used as the upper transistor of the BUCK circuit, and either the third MOSFET Q3 or the fourth MOSFET Q4 is used as the lower transistor of the BUCK circuit; wherein the remaining MOSFETs not selected as the upper or lower transistors are turned on.

[0084] In related technologies, Q1 and Q2 are typically used as a single unit as the upper transistor in a BUCK circuit, while Q3 and Q4 are used as a single unit as the lower transistor. The upper transistor is turned on by controlling Q1 and Q2 to conduct simultaneously, and turned off by controlling them simultaneously; similarly, the lower transistor is turned on by controlling Q3 and Q4 to conduct simultaneously, and turned off by controlling them simultaneously. This approach requires synchronous control of multiple MOSFETs, which is quite complex.

[0085] In this disclosure, when the battery power supply circuit 220 is in BUCK mode, the controller only needs to control either Q1 or Q2, which becomes the upper transistor of the BUCK circuit, while the other remains on. At this time, the on or off of the upper transistor in BUCK mode can be achieved by controlling the MOSFET that becomes the upper transistor, without the need to synchronously control the two MOSFETs, thereby reducing the control complexity of the controller and making the implementation simpler.

[0086] It should be noted that in BUCK mode, either Q1 or Q2 can be used as the upper tube, and similarly, either Q3 or Q4 can be used as the lower tube in BUCK mode.

[0087] For example, when Q1 is selected as the upper transistor and Q3 as the lower transistor, Q2 and Q4 are kept in a normally conducting state. The control of the upper and lower transistors in the BUCK circuit is achieved by controlling Q1 and Q3.

[0088] In some embodiments, Q1 and Q2 can be selected alternately as the upper tube, and Q3 and Q4 can be selected alternately as the lower tube.

[0089] Since the control frequency of the MOSFET selected as the upper or lower transistor in the BUCK circuit is different from that of the other transistor that is always on, the fatigue level between the MOSFETs can be balanced by selecting them alternately. This avoids the problem of one MOSFET being used significantly more times than the other, which would lead to excessively rapid lifespan degradation.

[0090] In some embodiments, a fifth MOSFET Q5 is connected in parallel across the inductor of the BUCK circuit. When power is supplied in charge pump mode, the fifth MOSFET Q5 is turned on; when power is supplied in BUCK mode, the fifth MOSFET Q5 is turned off.

[0091] In addition to controlling Q1, Q2, Q3, and Q4, the controller can also control Q5. In charge pump mode, Q5 is turned on; in BUCK mode, Q5 is turned off.

[0092] In some embodiments, the battery reduces the supply voltage via a power supply mode.

[0093] The battery provides a relatively high voltage. The supply voltage can be reduced by adjusting the power supply mode of the battery power supply circuit. This can reduce the battery discharge rate and extend the battery's battery life while still meeting the load circuit requirements.

[0094] Corresponding to the embodiments of the battery power supply mode determination method of this disclosure, this disclosure also provides embodiments of a corresponding battery power supply mode determination device.

[0101] In some embodiments, the charge pump mode is implemented based on a charge pump circuit, which includes a first MOSFET, a second MOSFET, a third MOSFET, and a fourth MOSFET. The BUCK mode is executed by: using either the first MOSFET or the second MOSFET as the upper transistor of the BUCK circuit, and using either the third MOSFET or the fourth MOSFET as the lower transistor of the BUCK circuit; wherein the remaining MOSFETs not selected as the upper or lower transistors are turned on.

[0102] In some embodiments, a fifth MOSFET is connected in parallel across the inductor of the BUCK circuit. When powered in charge pump mode, the fifth MOSFET is turned on; when powered in BUCK mode, the fifth MOSFET is turned off.
