Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

In the embodiments of the present application, "at least one" means one or more, and "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a alone, a and B together, and B alone, wherein a, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship. "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one (one) of a, b, or c may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or plural.

The "at … …" in the embodiment of the present application may be an instant when a certain situation occurs, or may be a period of time after a certain situation occurs, which is not particularly limited. In addition, the display interface provided by the embodiment of the application is only used as an example, and the display interface can also comprise more or less contents.

When the battery power of the electronic device is measured, the battery power of the electronic device can be measured by an entity power meter, or the battery power of the electronic device can be calculated by using a software code, wherein the mode of calculating the battery power by using the software code can be called a software power meter.

Because the physical electricity meter needs to occupy the volume of the electronic device and has high cost, in some implementations, the physical electricity meter is not used, but the battery power of the electronic device is calculated by means of a software electricity meter due to the consideration of the volume and the cost of the electronic device.

In the embodiment of the application, the electronic device may be a handwriting pen, a bluetooth headset, an intelligent watch, a Virtual Reality (VR) terminal device (such as VR glasses and VR game handle), etc., and the battery power of the electronic device may be calculated by means of a software power meter without using an entity power meter due to the consideration of the volume and cost of the electronic device.

FIG. 1 is a flow chart of the calculation of a software fuel gauge in some implementations. In fig. 1 and the following embodiments, a handwriting pen (stylus) is taken as an example.

As shown in fig. 1, a specific flow of the software fuel gauge calculation is as follows.

S101, initializing a software electricity meter algorithm.

In some implementations, the initialization of the software coulomb calculation may be assigning values to an initial battery charge, an initial battery voltage, etc., that are involved in the calculation process.

S102, judging whether a universal serial bus (universal serial bus, USB) interface of the handwriting pen is in place or not.

When the USB interface is in place, that is, when the handwriting pen is connected with the charging power supply, for example, the USB interface of the handwriting pen is connected with the USB interface of the electronic equipment, or the USB interface of the handwriting pen is connected with the charging power supply through a USB connecting wire, and the handwriting pen is in a charging state.

When the USB interface is not in place, that is, when the handwriting pen is not connected to the charging power supply, for example, the USB interface of the handwriting pen is not connected to the USB interface of the electronic device, or the USB interface of the handwriting pen is not connected to the charging power supply through the USB connection line, the handwriting pen is in a discharging state.

In a possible implementation, for a handwriting pen supporting wireless charging, whether the handwriting pen is in a charging state or a discharging state can be judged through whether a wireless charging coil of the handwriting pen is overlapped with a wireless charging coil of the electronic device. When the wireless charging coil of the handwriting pen is overlapped with the wireless charging coil of the electronic equipment, the handwriting pen is in a charging state; when the wireless charging coil of the handwriting pen is not overlapped with the wireless charging coil of the electronic equipment, the handwriting pen is in a discharging state.

S103, when the USB interface is in place, the handwriting pen executes a software fuel gauge charging algorithm.

When the USB interface is in place, namely the handwriting pen is in a charging state, the handwriting pen can calculate the battery electric quantity of the handwriting pen during charging through a software electric quantity meter charging algorithm. Specifically, the software electricity meter charging algorithm may calculate an increase value of the battery electricity through a preset charging current, so as to obtain the battery electricity when the handwriting pen is charged in real time.

For example, the stylus pen has a preset charging current i (t), according to the formulaThe time integration is carried out on the preset charging current, and the moment t1 is calculatedThe time period from the time t2 to the time when the electric quantity of the handwriting pen increases. According to the electric quantity of the handwriting pen at the time t1 and the calculated increment value of the electric quantity from the time t1 to the time t2, the electric quantity of the handwriting pen at the time t2 can be obtained.

S104, when the USB interface is out of place, the handwriting pen executes a software fuel gauge discharging algorithm.

When the USB interface is out of place, namely the stylus is in a discharging state, the stylus can calculate the battery power during discharging through a software fuel gauge discharging algorithm. Specifically, the software electricity meter discharging algorithm may be that, through a voltage detection device inside the handwriting pen, voltage values on two sides of a handwriting pen battery are periodically measured, a time integral is performed on a ratio of the measured battery voltage value to the internal resistance, and a decrease value of the battery electric quantity, that is, the discharging electric quantity of the battery is calculated, so that the battery electric quantity when the handwriting pen is discharged can be obtained in real time.

For example, the internal resistance value of the stylus is R, the time t1 is to the time t2, the voltage at two sides of the battery is periodically detected by the voltage detection device in the stylus, the voltage at two sides of the battery is detected to be u (t), and the formula is based on the following formulaAnd (3) performing time integration on the ratio of the battery voltage to the battery resistance, and calculating to obtain the reduction value of the electric quantity of the handwriting pen in the time period from the time t1 to the time t 2. According to the electric quantity of the handwriting pen at the time t1 and the calculated reduction value of the electric quantity from the time t1 to the time t2, the electric quantity of the handwriting pen at the time t2 can be obtained.

S105, judging whether the battery power of the handwriting pen is changed or not.

And after the battery electric quantity of the handwriting pen is obtained through calculation of a software electric quantity meter charging algorithm or a software electric quantity meter discharging algorithm, judging whether the battery electric quantity is changed or not.

When the battery power is not changed, the handwriting pen does not update the battery power.

And S106, when the battery power changes, the handwriting pen updates the battery power.

The stylus pen can send the updated battery power to a matched power display device, such as a tablet computer, through Bluetooth, and the electronic device can display the updated battery power of the stylus pen.

It can be understood that, according to the determination in step S105, after the battery power of the handwriting pen is not updated, or after the battery power of the handwriting pen is updated, the handwriting pen can continue to execute step S102 and subsequent steps, so as to realize continuous updating of the battery power of the handwriting pen.

However, in some implementations, the internal resistance used in calculating the battery level of the stylus in step S104 is fixed, and the internal resistance of the stylus may be different when the stylus is in different operating scenarios.

For example, a stylus operating scenario may include: write, empty mouse, stand unused, sleep, etc. The writing and drawing work scene can be that a user can use a handwriting pen to complete writing or drawing functions on the electronic equipment with the touch screen, for example, the user can use the handwriting pen to conduct writing and drawing operations on the touch screen of the electronic equipment to complete drawing of images or editing of characters; the working scene of the empty mouse can be that the handwriting pen can replace a mouse to operate the electronic equipment, for example, when the presentation is played, a user can use the empty mouse mode of the handwriting pen to replace the mouse to play the presentation; the work scene which is not used for standing can be a scene in which a user does not operate the handwriting pen temporarily; the dormant working scene can be a scene that a user does not use a handwriting pen for a period of time, and the handwriting pen enters a low-energy consumption state.

The internal resistance of the stylus may be different in different operating scenarios. If the internal resistances adopted in calculating the battery power are the same constant value for different working scenes, the deviation between the calculated battery power and the actual battery power may be larger.

In view of this, the embodiment of the application provides a method for calculating the battery power, which calculates the battery discharge power according to the internal resistance values corresponding to the same voltage under different scenes. That is, the calculation of the battery power can be performed according to the actual working scene of the electronic device through the internal resistance corresponding to the working scene, so that the accuracy of the calculation of the battery discharge power of the electronic device can be improved, more accurate power indication is given to the user, and the use experience of the user is improved.

It will be apparent to one skilled in the art that some of the specific details presented above with respect to the power display device 200 may not be required to practice a particular embodiment or equivalent thereof. Similarly, other electronic devices may include a greater number of subsystems, modules, components, etc. Some of the sub-modules may be implemented as software or hardware, where appropriate. It should be understood, therefore, that the foregoing description is not intended to be exhaustive or to limit the disclosure to the precise form disclosed herein. On the contrary, many modifications and variations will be apparent to those of ordinary skill in the art in light of the above teachings.

Next, a method for calculating battery power according to an embodiment of the present application will be described with reference to fig. 5 to 6, where the method is applied to an electronic device, and at least one correspondence is stored in the electronic device, and the correspondence includes: the corresponding relation between the working scenes, the battery voltage and the internal resistance value, wherein the internal resistance values corresponding to different working scenes and/or different battery voltages are different.

In the embodiment of the application, the electronic equipment can have one or more working scenes, and the working scenes of the electronic equipment can also be called as working modes of the electronic equipment.

Taking the example that the electronic device is a stylus, the working scenario may include any of the following scenarios: a write stroke scene, an air mouse scene, a rest unused scene, or a dormant scene.

The above scenario may refer to the relevant description of the handwriting pen working scenario in fig. 1, and will not be repeated here.

Taking the example that the electronic device is a bluetooth headset, the working scenario may include any one of the following scenarios: playing audio scenes, dormant scenes or shutdown scenes.

Under the audio playing scene, the Bluetooth headset is matched with the electric quantity display equipment for use, and the Bluetooth headset can play audio such as music, conversation and the like; when the user does not use the Bluetooth headset for a period of time, the Bluetooth headset can be in a dormant scene; when the user turns off the bluetooth headset, for example, after the user operates a shutdown button on the bluetooth headset, the bluetooth headset may be in a shutdown scene.

Taking the example that the electronic device is a smart watch, the working scenario may include any of the following scenarios: a normal operation scenario, a power saving operation scenario, a night operation scenario, or a shutdown scenario.

Under a conventional working scene, each functional module provided by the intelligent watch can normally operate, for example, the intelligent watch can normally provide functions such as music, games, short messages, telephones, heart rate detection, step count, clocks and the like. Under the power-saving working scene, part of functional modules provided by the intelligent watch can normally operate, for example, functions such as short messages, telephones, heart rate detection, step count, clocks and the like can normally operate, and functions such as music, games and the like are disabled. In a night work scene, the intelligent watch only allows key functional modules to normally operate, such as heart rate detection, clock and other functional modules to be disabled. Under the shutdown scene, all functions provided by the intelligent watch can not normally run.

The battery voltage may refer to the voltage of the battery of the electronic device.

The internal resistance value may refer to an internal resistance value of a battery of the electronic device.

The correspondence may be based on multiple experimental tests performed on the electronic device. For example, in each working scene, measuring the measured internal resistance values of a plurality of electronic devices with the same model under each voltage, and calculating an average value or a value near the average value of the measured internal resistance values measured under each voltage to obtain the corresponding relation between the battery voltage and the internal resistance value in each working scene; or under each working scene, measuring the measured internal resistance value of one electronic device under each voltage for multiple times, and calculating an average value or a value near the average value of the measured internal resistance values measured under each voltage to obtain the corresponding relation between the battery voltage and the internal resistance value under each working scene.

The obtained corresponding relation can be loaded into the electronic equipment, and when the subsequent electronic equipment calculates the battery power, the internal resistance value of the electronic equipment can be obtained based on the working scene and the battery voltage of the electronic equipment. For example, the electronic device may store the following correspondence: and under each working scene of the electronic equipment, the corresponding relation between the battery voltage and the internal resistance value. For example, for a first operating scenario, the battery voltage has a first correspondence with the internal resistance value; for the second working scene, the battery voltage and the internal resistance value have a second corresponding relation. In a possible implementation, the internal resistance value obtained according to the first corresponding relation of the battery voltages with equal magnitudes in the first working scene may be different from the internal resistance value obtained according to the second corresponding relation in the second working scene.

As shown in fig. 5, the method for calculating the battery power according to the embodiment of the present application is as follows:

s501, obtaining M battery voltage values obtained by the electronic equipment at M sampling moments; m is a positive integer.

In the embodiment of the application, the time interval between the M sampling moments may be a constant value, for example, the time interval of sampling is 0.5 seconds, which means that the voltage detection circuit obtains the voltage of the primary battery every 0.5 s; the time interval between the M sampling moments may also be a non-constant value, which is not particularly limited in the embodiment of the present application.

In one possible implementation, the electronic device may obtain, through a voltage detection circuit in the electronic device, a battery voltage value of the electronic device at M sampling moments. The voltage detection circuit may include an analog-to-digital converter (ADC) for converting a continuously varying analog voltage signal into a discrete digital voltage signal, and the voltage circuit may sample the battery voltage value based on the ADC.

Thus, in a period of time, the electronic device samples the battery voltage value through the voltage detection circuit, and if M sampling moments are T ₁ ，T ₂ ，……，T _M-1 ，T _M The battery voltage values that the electronic device can obtain at the M sampling moments include V ₁ ，V ₂ ，……，V _M-1 ，V _M Wherein M may be 1 or an integer greater than 1.

S502, combining the working scene and the corresponding relation of the electronic equipment to obtain the internal resistance values corresponding to the voltage values of the M batteries.

According to the working scene of the electronic equipment and the corresponding relation stored in the electronic equipment, the electronic equipment can obtain the internal resistance values corresponding to the M battery voltage values. For example, during a period of time, the electronic device obtains M battery voltage values V through the voltage detection circuit ₁ ，V ₂ ，……，V _M-1 ，V _M According to the working scene of the electronic equipment in the period of time and the corresponding relation stored in the electronic equipment, the electronic equipment can obtain the internal resistance value R corresponding to each of M battery voltage values ₁ ，R ₂ ，……，R _M-1 ，R _M Wherein M is a positive integer.

S503, according to the battery power change values of the electronic equipment, M current values comprise: ratio of the M battery voltage values to the respective corresponding internal resistance values.

According to ohm law i=u/R, where I is a current value, U is a voltage value, and R is a resistance value, the electronic device may obtain M current values by using ratios of M battery voltage values and respective corresponding internal resistance values. For example, between the first time and the second time, the electronic device obtains M battery voltage values as V based on step S501 ₁ ，V ₂ ，……，V _M-1 ，V _M Based on step S502, the electronic device obtains internal resistance values R corresponding to the M battery voltage values ₁ ，R ₂ ，……，R _M-1 ，R _M According to ohm's law, M current values I are obtained _1＝ V ₁ /R ₁ ，I _2＝ V ₂ /R ₂ ，……，I _M-1＝ V _M-1 /R _M-1 ，I _M＝ V _M /R _M 。

It will be appreciated that the charge is a current accumulated over time, and thus a battery charge change value for the electronic device may be derived based on the resulting M current values. The embodiment of the application does not limit the specific implementation of obtaining the battery power change value of the electronic equipment based on the M current values.

That is, by the method provided by the embodiment of the application, the electronic equipment can obtain the internal resistance corresponding to each voltage value of the battery in the working scene according to the working scene, so that the current value can be obtained through the voltage value and the internal resistance value of the battery, and the calculation of the change value of the electric quantity of the battery is performed based on the current value. Therefore, the accuracy of the calculation of the battery electric quantity of the electronic equipment can be improved, more accurate electric quantity indication is given to the user, and the use experience of the user is improved.

In a possible implementation, according to the battery power change values of the electronic device, the method specifically includes: and carrying out time integration on the M current values to obtain a battery power change value of the electronic equipment.

It can be understood that the current is the amount of charge passing through any cross section of the conductor in a unit time, and therefore, the battery power change value of the electronic device can be obtained by integrating the M current values in time.

The calculation formula for performing time integration on the M current values may be: wherein t is calculated in the formula ₁ To t _M This period is a period for the electronic device to acquire the M battery voltage values in step S501, and Δt may be a time interval of M sampling moments.

It will be appreciated that in some implementations, the M current values may also be integrated over time by other calculation methods, which is not particularly limited by the embodiment of the present application.

Therefore, the electronic equipment can accurately calculate the battery power change value of the electronic equipment according to the obtained current value, and further can acquire the battery power of the electronic equipment in real time.

In a possible implementation, before obtaining the M battery voltage values obtained by the electronic device at the M sampling moments, the method further includes: it is determined whether the electronic device is being charged. And when the electronic equipment is not charged, obtaining M battery voltage values obtained by the electronic equipment at M sampling moments.

That is, before the electronic device executes the method for calculating the battery power according to the embodiment of the present application, the electronic device needs to determine whether the electronic device is in a charging state. When the electronic device is not being charged, that is, when the electronic device is in a discharge state, the electronic device may perform steps S501 to S503.

Thus, the battery electric quantity calculation method provided by the embodiment of the application can accurately calculate the electric quantity of the battery when the electronic equipment is in a discharging state.

In a possible implementation, determining whether the electronic device is charging includes: judging whether a Universal Serial Bus (USB) interface of the electronic equipment is in an in-place state or not; when the USB interface is in a bit state, judging that the electronic equipment is being charged; when the USB interface is not in a bit state, the electronic equipment is judged not to be charged.

When the USB interface is in place, namely when the electronic equipment is connected to a charging power supply, the electronic equipment is judged to be charged. Taking a handwriting pen and a tablet computer as an example, when the USB interface of the handwriting pen is connected with the USB interface of the tablet computer, or the USB interface of the handwriting pen is connected with a charging power supply through a USB connecting wire, the handwriting pen is judged to be charged.

When the USB interface is out of place, namely the electronic equipment is not connected to the charging power supply, the electronic equipment is judged not to be charged. Taking a handwriting pen and a tablet computer as examples, when the USB interface of the handwriting pen is not connected with the USB interface of the tablet computer, or the USB interface of the handwriting pen is not connected with a charging power supply through a USB connecting wire, the handwriting pen is not in a charging state.

It will be appreciated that in some implementations, for an electronic device that supports wireless charging, it may also be determined whether the electronic device is charging or not charging by whether the wireless charging coil of the electronic device coincides with the wireless charging coil of the electronic device that is used to power the electronic device. When the wireless charging coil of the electronic device is overlapped with the wireless charging coil of the electronic device for supplying power, the electronic device is in a charging state; when the wireless charging coil of the electronic device is not coincident with the wireless charging coil of the electronic device for supplying power, the stylus pen is not in a charged state.

Therefore, whether the electronic equipment is being charged or not can be rapidly and accurately judged according to the in-place state of the USB interface of the electronic equipment.

In a possible implementation, when the electronic device is not charged, the battery power change value is subtracted from the power value of the electronic device to obtain an updated power value of the electronic device.

In the embodiment of the application, when the electronic equipment is not charged, the battery of the electronic equipment is continuously discharged, the battery electric quantity is lower and lower, and the battery electric quantity change value is subtracted from the electric quantity value of the electronic equipment, so that the updated electric quantity value of the electronic equipment can be obtained.

For example, the electronic device is not being charged from the first time to the second time, the power value of the electronic device corresponding to the first time is Q1, and the electronic device obtains, based on steps S501 to S503, the battery power change value of the electronic device between the first time and the second time is Q ', where the battery power corresponding to the second time, that is, the updated power value of the electronic device is Q1-Q'.

The residual electric quantity of the electronic equipment can be obtained rapidly and accurately by subtracting the battery electric quantity change value from the electric quantity value of the electronic equipment, and a user can estimate the usable time of the electronic equipment according to the residual electric quantity of the electronic equipment, so that the user experience is improved.

In a possible implementation, when the electronic device is being charged, the battery power variation value of the electronic device is obtained based on a preset charging current of the electronic device.

In the embodiment of the application, the preset charging current is based on a preset current value of the battery, and the preset charging current is usually a fixed value. It can be appreciated that the specific manner of obtaining the battery power change value based on the preset charging current of the electronic device may refer to the description of the software fuel gauge charging algorithm in step S103, which is not repeated herein.

It will be appreciated that the manner in which the software fuel gauge charging algorithm is calculated in accordance with embodiments of the present application is not particularly limited.

When the electronic device is being charged, the electronic device will also typically discharge, and in one possible implementation, the electronic device may obtain a battery power change value of the electronic device based on its preset charging current, without considering the discharging current of the electronic device, because the charging current of the electronic device is typically much greater than the discharging current, so that neglecting the discharging current has little influence on the accuracy of calculating the battery power change value.

Therefore, when the electronic equipment is being charged, the electronic equipment can accurately calculate the change value of the battery electric quantity during charging, and the calculation resource can be saved.

In the implementation, when the electronic equipment is being charged, a battery power change value is added to the power value of the electronic equipment, so as to obtain an updated power value of the electronic equipment.

It can be understood that when the electronic device is charged, the battery power of the electronic device is higher and higher, and the battery power change value is added to the power value of the electronic device, so that the updated power value of the electronic device can be obtained.

For example, from the first moment to the second moment, the electronic device is in a charging state, the electric quantity value of the electronic device corresponding to the first moment is Q1, the electronic device obtains, based on a preset charging current, a change value of the battery electric quantity of the electronic device between the first moment and the second moment is Q ', and then the battery electric quantity corresponding to the second moment, that is, the updated electric quantity value of the electronic device is q1+q'.

Through adding battery electric quantity change value in the electric quantity value of electronic equipment, can be accurate, real-time obtain the battery electric quantity of electronic equipment under the state of charge, electronic equipment can in time stop the charging according to self battery electric quantity, prevents that the battery from overcharging, prolongs the life of battery.

When the electronic device is being charged, in another possible implementation, a first battery power change value of the electronic device may be obtained based on a preset charging current of the electronic device, and a second battery power change value of the electronic device may be obtained according to the M current values; and calculating the difference value between the first battery power change value and the second battery power change value to obtain the battery power change value of the electronic equipment.

That is, when the electronic device is being charged, the electronic device will also discharge, and the electronic device may obtain the change value of the battery power according to the increase value of the battery power during charging and the decrease value of the battery power during discharging.

For example, the electronic device obtains a first battery power change value of the electronic device between the first time and the second time to be Q1 based on a preset charging current from the first time to the second time; based on the steps S501 to S503, the electronic device obtains the change value of the battery power of the electronic device from the first time to the second time as Q2, and the change value of the battery power of the electronic device from the first time to the second time is Q1-Q2.

Therefore, when the electronic equipment is being charged, the electronic equipment can accurately calculate the change value of the electric quantity of the battery based on the charging current and the discharging current of the battery.

S6041, when the USB interface is out of place, acquiring the working scene of the electronic equipment.

Taking a handwriting pen as an example, the manner of judging the working scene by the handwriting pen can be as follows: an acceleration chip can be arranged in the handwriting pen, and the handwriting pen can be judged to be in a dormant scene or a static unused scene according to a preset value obtained by the acceleration chip; the pressure sensing chip can be arranged in the handwriting pen, and when the pressure sensing chip detects that the pen point of the handwriting pen has pressure, the handwriting pen can be judged to be in a writing scene; the handwriting pen can be provided with a key for switching the air mouse scene, and when the handwriting pen detects that the key is used for switching the working scene of the handwriting pen to the air mouse scene, the handwriting pen can be judged to be in the air mouse scene.

It may be appreciated that, in some implementations, the electronic device may also determine the working scenario of the electronic device by other manners, and the manner of determining the working scenario is not specifically limited in the embodiments of the present application.

S6042, the electronic equipment executes a battery electric quantity calculation method.

It is to be understood that the order of steps S6041 and S6042 is not fixed, and the electronic apparatus may execute step S6041 first and then step S6042, or may execute steps S6041 and S6042 simultaneously, which is not particularly limited in the embodiment of the present application.

S605, judging whether the battery power of the electronic equipment is changed.

And after the battery electric quantity of the electronic equipment is calculated by a software electric quantity meter charging algorithm or a battery electric quantity calculation method, judging whether the battery electric quantity is changed or not.

When the battery power change value is 0, the electronic device does not update the battery power.

And S606, when the battery power changes, the electronic equipment updates the battery power.

When the battery power change value is not 0, the electronic equipment updates the battery power. For the electronic equipment which is being charged, the method for updating the battery power of the electronic equipment is that the battery power change value is added to the power value of the electronic equipment; for a discharging electronic device, the electronic device updates the battery charge by subtracting the battery charge change value from the electronic device charge value.

It can be understood that, according to the determination in step S605, the battery power of the electronic device is not updated, or after the battery power of the electronic device is updated, the electronic device may continue to execute step S602 and the subsequent steps, so as to implement continuous updating of the battery power of the electronic device.

It can be understood that, after determining that the electronic device is in the charging state according to step S602, the electronic device will also discharge, and when calculating the battery power change value, the discharged power change value may be ignored in consideration of the battery power change value relative to the charging, so that the battery power change value may be calculated only according to the preset charging current; the charged battery power variation value and the discharged battery power variation value can also be calculated at the same time, that is, the electronic device executes step S603 and steps S6041-S6042 at the same time, and the battery power variation value of the electronic device is obtained according to the difference value of the charged battery power variation value and the discharged battery power variation value.

Thus, the electronic equipment can calculate the battery power of the electronic equipment in real time based on the software power meter charging algorithm and the battery power calculation method provided by the embodiment of the application. When the electronic equipment discharges, the calculation of the battery electric quantity can be carried out according to the actual working scene of the electronic equipment through the internal resistance corresponding to the working scene, the accuracy of the calculation of the battery discharge electric quantity of the electronic equipment can be improved, more accurate electric quantity indication is given to a user, and the use experience of the user is improved.
