[0025] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0027] In order to solve the above technical problems, the present application provides a control method for a power chip. The control method for a power chip provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0028] like Figure 1 As shown, Figure 1 : is a flow chart of a control method of a power chip provided by an embodiment of the present application. The embodiment of the present application provides a control method of a power chip. The electronic device includes a power chip, a power module and an energy storage module. The power module and the energy storage module are respectively located on different power supply lines of the power chip. The method may include:

[0029] S101, obtaining a first temperature of a mainboard of the electronic device and a first load current output by the power chip to the power module;

[0030] The energy conversion efficiency of a power chip refers to the ability of the power chip to effectively convert input electrical energy into the electrical energy required by the load. A higher conversion efficiency means that more input electrical energy is converted into effective output electrical energy rather than wasted on ineffective energy such as heat. The inventors have found that energy conversion efficiency is usually related to load current. If the load current required by the load is low, the energy conversion efficiency of the power chip is also low, which will cause a large efficiency loss.

[0031] In this embodiment, the electronic device can be a mobile phone, a tablet computer, a smart watch, etc. The electronic device includes a power supply module, a power chip, a power module and an energy storage module. Among them, the power supply module is the power supply of the entire electronic device, which supplies power to the power chip, the power module and the energy storage module. The power chip is responsible for managing the power supply in the electronic device. The power chip can convert the unstable voltage and current output by the battery into stable voltage and current to power the power module and the energy storage module. The power module refers to the part of the electronic device that actually uses electrical energy, such as a processor, a screen, etc. These modules directly use the current output by the power chip to complete the normal functions of the device. The energy storage module is mainly used to temporarily store the electrical energy output by the power chip. When the load current is insufficient, it obtains additional current from the power chip by "drawing load" to help the power chip maintain the best energy conversion efficiency.

[0032] In this embodiment, the system detects the first temperature of the current electronic device mainboard and obtains the first load current currently output by the power chip to the power module. The mainboard of the electronic device refers to the core circuit board in the electronic device, which connects and manages all modules in the electronic device, provides a transmission channel for data and power, and ensures that the modules work together.

[0033] S102, determining a target load current corresponding to the first temperature; the target load current is a load current output by the power chip when the power conversion efficiency at the first temperature meets a first condition;

[0034] In this embodiment, based on the detected first temperature of the mainboard, the system calculates a target load current, which is the current required for the electronic device to meet the first condition for the power conversion efficiency at the first temperature. For example, the first condition can achieve the highest power conversion efficiency for the electronic device. Among them, the power conversion efficiency refers to the ratio of the power chip converting the power input from the power supply module into the output power actually used by the electronic device. The power conversion efficiency ranges from 0% to 100%. Higher power conversion efficiency means less energy waste and more power is used for equipment operation. Conversely, if the power conversion efficiency is low, it means that more power is wasted in the form of heat, etc.

[0035] As an optional embodiment, Figure 2As shown, the power supply module can be a battery. When the power chip only serves the power module, the calculation formula for the power conversion efficiency is:

[0036]

[0037] Wherein, η represents the power conversion efficiency, Va and Ia represent the input voltage and input current of the power chip respectively, and Vb and Ib represent the output voltage and output current of the power chip respectively.

[0038] The power conversion efficiency is mainly affected by the load current and temperature of the power chip. For example, as the load current increases, the power conversion efficiency of the power chip gradually increases. When the load current reaches a certain value, the power conversion efficiency approaches its maximum value. For another example, within the normal temperature range, the higher the temperature, the higher the power conversion efficiency of the power chip. For example, when the temperature rises from -10°C to 25°C, the efficiency continues to increase.

[0039] As an optional embodiment, Figure 3 As shown in the figure, at each temperature, the power chip has a corresponding target load current. At a certain temperature, as the load current increases, the efficiency of the power chip continues to improve until the load current reaches a certain current value, and its power conversion efficiency reaches the maximum and tends to be stable. This current value is the target load current. At this target load current, the power chip can convert the input power into output power with the highest power conversion efficiency. Even if the load current continues to increase, the power conversion efficiency will not increase significantly. Figure 3 As shown, at 25°C, the load current of the target load current is 100mA. At 0°C, the load current of the target load current is 300mA. At -10°C, the load current of the target load current is 500mA. Then in this embodiment, after determining the temperature of the mainboard, the target load current corresponding to the temperature can be obtained.

[0040] In some embodiments, before determining the target load current corresponding to the first temperature, the method includes:

[0041] Obtaining target load currents corresponding to a plurality of temperatures of a mainboard of the electronic device;

[0042] Fitting multiple temperatures of the mainboard of the electronic device and target load currents corresponding to the multiple temperatures of the mainboard of the electronic device, to obtain a corresponding relationship between the temperature and the target load current;

[0043] The determining a target load current corresponding to the first temperature includes:

[0044] The target load current corresponding to the first temperature is determined according to the corresponding relationship between the temperature and the target load current.

[0045] In this embodiment, the system can first obtain multiple temperatures of the electronic device and the target load currents at different temperatures, and then perform data fitting between these temperatures and the target load currents corresponding to each temperature to obtain a function that can represent the corresponding relationship between the temperature and the target load current. This function can calculate the target load current of the power chip at any temperature.

[0046] Therefore, when the system is running, the current first temperature of the mainboard is detected, and the target load current at the first temperature is determined through the fitted corresponding relationship. This is the most suitable operating current for the power chip at the current first temperature, which can ensure that the power conversion efficiency of the electronic device at the first temperature meets the first condition.

[0047] For example, the first condition may be that the power conversion efficiency of the electronic device is the highest. Then, the efficiency curves at multiple temperatures can be obtained through testing. The efficiency curve represents the curve of the energy conversion efficiency of the power chip at a certain temperature as the load current changes. The set of efficiency curves at multiple temperatures is determined as the following formula:

[0048] P = {η t (I)}

[0049] Wherein, P represents a collection of efficiency curves at multiple temperatures, t represents different temperatures, η represents the power conversion efficiency at different load currents, and I represents different load currents.

[0050] Then, the target load current corresponding to each temperature can be determined from these efficiency curves, that is, the load current when the electric energy meets the first condition, and the set of these target load currents can be expressed as the following formula:

[0051] I t ={I}

[0052] Where I represents the target load current and t represents different temperatures.

[0053] Subsequently, these target load currents can be fitted to calculate the corresponding relationship between temperature and target load current, and finally the following fitting formula is obtained:

[0054] Q t =f(t)

[0055] Where Q is the target load current and t represents different temperatures.

[0056] In this way, by obtaining the target load current at different temperatures and fitting to establish the corresponding relationship between temperature and load current, the system can accurately determine the optimal load current at a specific temperature. This ensures that the power chip always operates at the optimal efficiency point and minimizes energy loss.

[0057] S103, when the first load current is less than the target load current, controlling the power chip to supply power to the energy storage module, so as to adjust the current output by the power chip from the first load current to the target load current.

[0058] In the embodiment of the present application, if the first load current output by the power chip to the power module is lower than the target load current, it means that the current power chip has not achieved the best power conversion efficiency, and the system will start the energy storage module to obtain additional current from the power chip by withdrawing the load. In this way, the output current of the power chip can be increased from the first load current to the target load current, so that the power chip works at the best efficiency point and reduces the loss of power.

[0059] In an embodiment of the present application, the target load current of the power chip at the current temperature can be determined by detecting the temperature of the mainboard and the load current of the current power module. The target load current is the load current output by the power chip when the power conversion efficiency meets the first condition at the current mainboard temperature. When the actual load current is less than the target load current, the system increases the load current by controlling the power chip to supply power to the energy storage module, and adjusts the output current of the power chip to the target load current. In this way, the power chip works in a more efficient state, reducing the efficiency loss caused by the load current being too small, thereby improving the energy conversion efficiency.

[0060] In some embodiments, controlling the power chip to supply power to the energy storage module includes:

[0061] determining a second load current according to a difference between the target load current and the first load current;

[0062] The power chip is controlled to supply power to the energy storage module according to the second load current.

[0063] In this embodiment, the system first compares the actual first load current with the target load current with the highest power conversion efficiency. If the actual first load current is less than the target load current, a difference will be generated, indicating that the power chip is not currently operating at the optimal efficiency. That is, the difference between the target load current at the current first temperature and the actual first load current can be calculated as the second load current. Then, the power chip can be controlled to supply power to the energy storage module with the second load current. By supplying power to the energy storage module, the total output current of the power chip can be increased to reach the target load current, thereby achieving the highest energy conversion efficiency.

[0064] Furthermore, the second load current supplied to the energy storage module will not be consumed by the actual power consumption module, but will be temporarily stored by the energy storage module.

[0065] In this way, the power chip can operate at a higher power conversion efficiency without wasting extra output power.

[0066] In some embodiments, the electronic device further includes a power supply module, and the power supply module is used to supply energy to the power chip; the method further includes:

[0067] When the energy storage module stores electric energy, the energy storage module is controlled to release the electric energy to the power supply module.

[0068] In this embodiment, after the power chip outputs the second load current to the energy storage module, the energy storage module can convert the second load current into electrical energy, and when it is detected that electrical energy is stored in the energy storage module, the system will control the energy storage module to discharge to the power supply module, release the stored electrical energy and transmit it back to the power supply module. The energy storage module can be a capacitor.

[0069] In this way, the energy storage module releases the excess electric energy accumulated in the previous load withdrawal process back to the power supply module, avoiding the waste of electric energy. And by recycling this energy, the energy efficiency of the entire system can be improved.

[0070] In some embodiments, the electronic device further includes a comparator and a first switch module, the comparator is connected to the power chip, the power module and the energy storage module, the first end of the first switch module is connected to the power chip, the second end of the first switch module is connected to the positive electrode of the energy storage module, and the control end of the first switch module is connected to the comparator;

[0071] When the first load current is less than the target load current, controlling the power chip to supply power to the energy storage module includes:

[0072] When the comparator detects that the first load current is less than the target load current, the comparator controls the first end and the second end of the first switch module to be turned on;

[0073] Wherein, when the first end and the second end of the first switch module are turned on, the power chip outputs a second load current to the energy storage module.

[0074] In this embodiment, the first switch module is used to control whether the power chip supplies power to the energy storage module, and the comparator is used to detect the difference between the actual load current and the target load current, and control the switch state of the first switch module according to the comparison result.

[0075] Specifically, the comparator can monitor the actual first load current. If the comparator detects that the first load current is less than the target load current, the comparator will send a control signal to conduct the first end and the second end of the first switch module. When the first load current is turned on, the power chip will start to output current to the energy storage module, that is, the second load current. After the power chip outputs current to the energy storage module, the total output current of the power chip is the sum of the first load current and the second load current. Finally, the current output by the power chip is adjusted to the target load current, so that the power chip can reach the optimal efficiency point.

[0076] For example, Figure 4 As shown, the first switch module can be a PMOS transistor, the source of the PMOS transistor is connected to the power chip, the drain is connected to the energy storage module, and the gate is controlled by a comparator. When the comparator detects that the first load current is less than the target load current, the comparator will control the gate voltage of the PMOS to be lower than the source voltage, that is, when the gate is negative relative to the source voltage, the control signal is 0, at which time the energy storage module turns on the energy storage function, and the PMOS is turned on. When the comparator detects that the first load current is greater than or equal to the target load current, the comparator will control the gate voltage of the PMOS to be not lower than the source voltage, that is, when the gate is positive relative to the source voltage, the control signal is 1, the energy storage module turns off the energy storage function, and the PMOS is turned off.

[0077] In the above manner, the load current can be monitored by the comparator, and the first switch module can be controlled to adjust the power supply chip to supply power to the energy storage module, so as to adjust the load current. When the current first load current is less than the target load current, the first switch module is turned on, and the power supply chip supplies power to the energy storage module until the load current reaches the target load current, thereby ensuring that the power supply chip operates at the highest efficiency point.

[0078] In some embodiments, the electronic device further includes a comparator and a second switch module, the comparator is connected to the power chip, the power module and the energy storage module, a first end of the second switch module is connected to the power supply module, a second end of the second switch module is connected to the negative electrode of the energy storage module, and a control end of the second switch module is connected to the comparator;

[0079] The controlling the energy storage module to release electric energy to the power supply module comprises:

[0080] Controlling the first end and the second end of the second switch module to be conductive;

[0081] Wherein, when the first end and the second end of the second switch module are turned on, the energy storage module releases electric energy to the power supply module.

[0082] In this embodiment, the second switch module is used to control whether the power supply chip controls the energy storage module to release electric energy to the power supply module, and the comparator is used to monitor and judge whether the electric energy in the energy storage module needs to be released to the power supply module, and control the conduction and shutdown of the second switch module according to the monitoring results.

[0083] Specifically, the comparator detects the current state of the circuit and determines whether the electric energy in the energy storage module needs to be transmitted back to the power supply module. If the electric energy in the energy storage module is greater than 0, the comparator will send a control signal to control the second switch module to turn on; if the electric energy in the energy storage module is equal to 0, the comparator will send a control signal to control the second switch module to turn off.

[0084] For example, Figure 4 As shown, the power supply module is a battery, the second switch module can be an NMOS transistor, the source of the NMOS tube is connected to the battery, the drain of the NMOS tube is connected to the negative electrode of the energy storage capacitor, and the gate of the NMOS tube is connected to the comparator. When the comparator detects that the electric energy in the energy storage module is greater than 0, the comparator will control the NMOS to turn on, and the current in the energy storage module will flow from the energy storage module through the NMOS to form a loop, and transfer the electric energy back to the power supply module. When the comparator detects that the electric energy in the energy storage module is 0, the comparator will control the NMOS to turn off.

[0085] In the above manner, when the system needs to recover the energy in the energy storage module, the second switch module can be controlled to conduct, and the electric energy stored in the energy storage module can be released to the power supply module. This mechanism ensures that the device can efficiently utilize the stored energy during the energy recovery phase, reduce energy waste, and improve overall energy efficiency.

[0087] Specifically, Figure 4 As shown, the control module includes a comparator and a first switch module, the comparator is connected to the power chip, the power module and the energy storage module, the first end of the first switch module is connected to the power chip, the second end of the first switch module is connected to the positive electrode of the energy storage module, and the control end of the first switch module is connected to the comparator. The control module also includes a second switch module, the first end of the second switch module is connected to the power supply module, the second end of the second switch module is connected to the negative electrode of the energy storage module, and the control end of the second switch module is connected to the comparator.

[0091] The adjustment module 603 is used to control the power chip to supply power to the energy storage module when the first load current is less than the target load current, so as to adjust the current output by the power chip from the first load current to the target load current.

[0092] In the present application, the target load current of the power chip at the current temperature can be determined by detecting the temperature of the mainboard and the load current of the current power module. The target load current is the load current output by the power chip when the power conversion efficiency meets the first condition at the current mainboard temperature. When the actual load current is less than the target load current, the system increases the load current by controlling the power chip to supply power to the energy storage module, and adjusts the output current of the power chip to the target load current. In this way, the power chip works in a more efficient state, reducing the efficiency loss caused by the load current being too small, thereby improving the energy conversion efficiency.

[0118] In the present application, the target load current of the power chip at the current temperature can be determined by detecting the temperature of the mainboard and the load current of the current power module. The target load current is the load current output by the power chip when the power conversion efficiency meets the first condition at the current mainboard temperature. When the actual load current is less than the target load current, the system increases the load current by controlling the power chip to supply power to the energy storage module, and adjusts the output current of the power chip to the target load current. In this way, the power chip works in a more efficient state, reducing the efficiency loss caused by the load current being too small, thereby improving the energy conversion efficiency.
