Technical Field

The present application relates to the field of power electronics technologies, and in particular, to a battery power display method, an electronic device, a program product, and a medium.

Background

The coulometer is one of the key components for calculating the electric quantity of the battery in the electronic equipment, and can obtain the coulomb value according to the charge-discharge current accumulation of the battery and transmit the coulomb value to the processor in the equipment, so that the processor can calculate the electric quantity of the battery based on the coulomb value, namely the real electric quantity.

However, after the processor obtains the actual power, it cannot guarantee that the power of the UI displayed on the User Interface (UI) is refreshed in time, so the power of the UI remains as the previous actual power, and the power of the UI displayed on the electronic device is inaccurate.

Disclosure of Invention

The application provides a battery power display method, electronic equipment, a program product and a medium, and aims to solve the problem that the UI power is inaccurate due to untimely refreshing.

In order to achieve the above object, the present application provides the following technical solutions:

the application provides a battery power display method, which is applied to electronic equipment, and the battery power display method comprises the following steps: determining the real electric quantity of a battery according to the coulomb value of the battery in the electronic equipment; determining a refresh period corresponding to the current according to the current of the battery; when the current is larger and the coulomb value obtained by integration is faster, the refresh cycle of the electric quantity refresh module can be set to be smaller, so that the refresh speed is faster; and then refreshing and displaying the UI electric quantity of the user interface by using the real electric quantity according to a refreshing period, so that the UI electric quantity can be timely refreshed and displayed, and the method can be suitable for high-power charging scenes.

In one possible embodiment, the refresh period is inversely proportional to the absolute value of the current. For example, determining a refresh period corresponding to a current according to the current of the battery specifically includes: according to the display precision of the UI electric quantity, determining the unit capacity represented by the minimum display unit of the UI electric quantity; the time required to reach the unit capacity in current is determined as the refresh period. And within the time range of each refreshing period, the rising amplitude of the electric quantity is not more than 1%, so that under the condition that the UI electric quantity is matched with the real electric quantity, the electric quantity is further displayed smoothly, and the electric quantity is prevented from jumping.

In a possible implementation manner, after the refresh period corresponding to the current is determined according to the current of the battery, the refresh period at the current may be further adjusted and updated according to the difference between the actual power and the UI power. Specifically, the refresh cycle may be updated with the aim that the UI power is equal to the real power before the real power reaches the charge/discharge limit of the battery. For example, firstly, determining a catch-up refresh period required to be adopted for realizing a target according to the running state of a battery; and updating the refresh period by the catch-up refresh period. Furthermore, determining the catch-up refresh period required to be adopted to achieve the target according to the operating state of the battery may specifically include: if the running state of the battery is a charging state, calculating to obtain a catch-up refresh period by taking the proportion of the sum of the real electric quantity and the preset value to the sum of the UI electric quantity and the preset value as the proportion of the refresh time to the catch-up refresh period; and if the running state of the battery is a discharging state, calculating to obtain the catch-up refresh period by taking the proportion of the sum of the UI electric quantity and the preset value to the sum of the real electric quantity and the preset value as the proportion of the refresh time to the catch-up refresh period. And then the difference between the UI electric quantity and the real electric quantity can be eliminated within the range represented by the preset value.

In a possible embodiment, the preset value is the smaller of the two following values: absolute value of difference between the real electric quantity and the charge and discharge limit value in the corresponding operation state; and the absolute value of the difference between the real electric quantity and the charge-discharge limit value in the corresponding operation state, and the absolute value of the difference between the real electric quantity and the UI electric quantity are respectively summed after corresponding weights are taken. And further, the phenomenon that the preset value is too large can be avoided, and the adjusting effect is ensured. Moreover, in a possible implementation manner, the absolute value of the difference between the actual electric quantity and the charge and discharge limit value in the corresponding operation state may be 20% of the empirical value; and the absolute value of the difference between the real electric quantity and the UI electric quantity, the corresponding weight can be an empirical value of 3.

In a possible embodiment, before determining the refresh period corresponding to the current according to the current of the battery, it is also possible to: firstly, carrying out abnormity screening on a plurality of continuous sampling values of the current; if the plurality of continuous sampling values are not abnormal, the average value of the plurality of continuous sampling values is used as the current, and the subsequent steps are executed, so that the calculation deviation caused by abnormal sampling is avoided.

The embodiments of the present application relate to a plurality of numbers greater than or equal to two. It should be noted that, in the description of the embodiments of the present application, the terms "first", "second", and the like are used for distinguishing the description, and are not to be construed as indicating or implying relative importance or order.

In electronic devices, a coulometer shown in fig. 1 is generally used as a fuel gauge to calculate the amount of electricity of a battery. The coulometer includes: an Analog-to-digital converter (ADC), a counter (e.g., counter shown in fig. 1), and a Real-time communication module (RTC) for clock synchronization. In the power transmission branch of the battery, usually in its negative branch, a corresponding detection resistor R is provided _sense The resistance value can be about 5 to 10m omega; ADC is used for detecting the resistance R _sense Voltage V across _Rsense After the collection and conversion treatment, the current passing through the detection resistor R is obtained _sense Current of (I) _Rsense (ii) a Then, the counter passes through the formula Q _R ＝∫I _Rsense dt, calculating to obtain the coulomb value Q of the battery _R And output.

In FIG. 1, the current I is measured _Rsense The direction of (d) is shown by way of example for battery discharge; when the battery is charged, its current I _Rsense In the opposite direction to that shown in figure 1.

The processor of the electronic equipment can transmit the coulomb value Q according to the fuel gauge _R To calculate the coulomb value Q _R The proportion in the total capacity of the battery is obtained, and then the real electric quantity of the battery is obtained; and then, refreshing and displaying the UI electric quantity according to a fixed refreshing period and the real electric quantity. However, when the coulomb value Q _R When the change is fast, the real electric quantity calculated by the processor may change for many times in the corresponding refreshing period, and the UI electric quantity stays at the real electric quantity in the last refreshing; orUnder special scenes (such as Relax described in fig. 2) such as Full power (such as Battery Full shown in fig. 2), low power (such as Battery Empty shown in fig. 2), or startup for the first time after abnormal power failure, startup for the first time after normal low power shutdown, startup for the first time after mobile phone failure shutdown, the actual power (such as dashed line shown in fig. 2) needs to be calibrated due to integration error, which may cause power mutation, and if refresh is not timely, UI power (such as solid line shown in fig. 2) may have a large deviation from the actual power; both of these situations result in low display accuracy of the battery level.

Especially in a high-power charging scenario of the electronic device, taking a mobile phone as an example, the status bar in fig. 3a and the screen locking interface in fig. 3b both display the UI power, because the coulomb counter integration speed is very fast, the refresh of the UI power cannot catch up with the rising speed of the real power, and further the displayed UI power is significantly delayed, and the user feels that the charging is slow; therefore, the UI power is required to be refreshed in time in a high-power charging scene, so that the UI power keeps up with the rising speed of the real power.

Based on the above, the application provides a battery power display method to solve the problem that the UI power is inaccurate due to untimely refreshing.

In addition, the interface can also be used for connecting other electronic devices, such as AR devices and the like.

The charging management module 140 is used to receive charging input from an external charger. The charging management module 140 may also supply power to the electronic device through the power management module 141 while charging the battery 142. The power management module 141 is used for connecting the battery 142, the charging management module 140 and the processor 110. The power management module 141 receives the input of the battery 142 and/or the charging management module 140, and supplies power to the processor 110, the internal memory 121, the speaker 170A, the external memory, the motor 191, the flexible screen 194, the camera 193, the wireless communication module 160, and the like through corresponding power conversion circuits.

In order to solve the problem of low UI power display accuracy caused by untimely refreshing, the following battery power display method is executed by the processor 110 in the embodiment of the present application; when the battery power display method is executed, the communication relationship between the software architecture inside the processor 110 and the devices related to the hardware layer of the electronic device is as shown in fig. 5:

in the hardware layer, the charging chip (such as the Charge IC shown in fig. 5) is the main device of the charging management module 140 in fig. 4, the power management chip (such as the PMIC shown in fig. 5) is the main device of the power management module 141 in fig. 4, the Fuel Gauge (such as the Fuel Gauge shown in the figure) is responsible for executing the above-mentioned collecting and calculating process of the coulometer, and its internal register is through I ² C interface calculates the coulomb value Q _R And collecting the obtained current I _Rsense Are both transmitted to the electricity meter drive of the inner core layer.

The kernel layer is a layer between hardware and software. The kernel layer at least includes a touch screen Driver (TP Driver), a display Driver (e.g., LCD/LED screen Driver), a Graphics Processing Unit (GPU) Driver, a sensor Driver, and the like, which is not limited in this embodiment of the present application. Only a part relevant to the present application is shown in fig. 5: electricity meter driving and charging and discharging services; the electric quantity refreshing module in the charging and discharging service is responsible for the coulomb value Q transmitted according to the drive of the fuel gauge _R Calculating the coulomb value Q _R And obtaining the real electric quantity of the battery according to the ratio of the real electric quantity to the total capacity of the battery, and refreshing and displaying the UI electric quantity according to the real electric quantity according to a certain refreshing period. In addition, in the charging and discharging service, an electric quantity refreshing algorithm module is additionally added in the embodiment to drive the transmitted current I according to the electric quantity meter _Rsense Calculating the adaptive refreshing period in real time to replace the originally adopted fixed refreshing period of the electric quantity refreshing module; thus, when the current I is _Rsense The larger the coulomb value Q obtained by integration _R When the change is faster, if the refresh period of the electric quantity refresh module is set to be smaller, the refresh period and the current I are also set _Rsense And inversely, the refresh speed of the battery pack is higher, timely refresh display of the UI electric quantity is ensured, and the battery pack is suitable for a high-power charging scene.

Then, the power refreshing module may report the power to a status bar of the application layer and a System user interface (e.g., system UI shown in fig. 5) through a Heathd service of the Framework layer, and finally, UI power display on the electronic device is realized.

The Framework layer is used for providing an Application Programming Interface (API) and a programming Framework for an application program of the application layer. The Framework layer includes a number of predefined functions. The Framework layer may further include a view system (view system), an activity manager (package manager), a content provider (content provider), a resource manager (resource manager), an input system (input system), which are not shown in fig. 5.

The application layer may include a series of applications and may also include system services. System services refer to programs, routines, or processes that perform specified system functions in order to support other programs. In practice, the series of application programs generally includes: applications (APP) such as cameras, maps, bluetooth, contacts, short messages, etc.; only the status bar and systemuui referred to in the embodiments of the present application are shown in fig. 5.

It should be noted that the thin solid line with arrows in fig. 5 represents a data transmission line, but the data transmission between any two in practical application is not limited to the direction shown by the arrows in the figure.

That is, the power refresh algorithm module is based on the current I _Rsense The business logic for calculating the refresh period is the key point for realizing timely refresh, and a specific example is that the refresh period is inversely proportional to the current I _Rsense Absolute value of (d); for example, it may be possible to refer to UI _ refresh _ time = C/100/| I _Rsense To enable calculation of the refresh period UI refresh time(ii) a Wherein, C is the total capacity (unit is mAh) of the battery, when the UI electric quantity is displayed in 100 grids, the capacity corresponding to each grid of electric quantity is C/100; under the condition of constant charging current or discharging current, the time consumption is C/100/| I theoretically every time one grid of electricity is increased _Rsense 60 minutes; assuming that the total capacity of the battery C =5000mAh, and the capacity corresponding to one cell of electricity is 50mAh, if the current I is I _Rsense At 2A, each grid of electricity is used for 50/1000/2 × 60=1.5min when the electricity is increased. If the calculation is done in seconds, the refresh period UI _ refresh _ time = C/100/| I _Rsense 3600 seconds. In the time range of each refreshing period UI _ refresh _ time, the electric quantity rising amplitude is not more than 1%, further under the condition that the UI electric quantity is matched with the real electric quantity, electric quantity smooth display is further realized, and electric quantity jumping is avoided.

It is worth noting that when the current I of the battery is _Rsense When the values are different, the corresponding electric quantity change speeds are also different; namely, the difference value between the real electric quantity and the UI electric quantity is different during each refreshing; if the difference is large, the user is inevitably subjected to the feeling of electric quantity jump; if the difference is small, such as less than 1%, the refresh action is meaningless. Especially the current I _Rsense When the current is constant, the refresh period UI _ refresh _ time also keeps a fixed value, and the difference value between the real electric quantity and the UI electric quantity is maintained until the current I _Rsense A change occurs. Therefore, after the refresh period UI _ refresh _ time is calculated by the above formula, the current I can be further measured according to the difference between the actual electric quantity and the UI electric quantity _Rsense The next refresh period UI refresh time is adjusted and updated. Several specific scenario examples are given below:

example one: the actual charge is greater than the UI charge and the battery is charging.

Recording Real electric quantity as Real _ SOC, UI electric quantity as UI _ SOC, wherein the UI electric quantity lags behind the Real electric quantity at the moment, and the laggard specific difference value Diff _ SOC = | Real _ SOC-UI _ SOC |; because the corresponding limit value of the electric quantity is 100% in the charging state, the UI electric quantity can be driven to 100% at the latest when the real electric quantity reaches 100%; therefore, there are two factors that may affect the UI power to chase the refresh period of the Real power, one is remaining power remaining _ SOC =100% -Real _ SOC that is fully charged, and the other is the difference value Diff _ SOC between the two; a certain weight is taken for each of the two influence factors, which are respectively denoted as K1 and K2, so that a total influence factor K can be calculated, i.e., K = K1 Diff _ SOC + K2 Remain _ SOC.

Then, according to a proportional formula of UI _ refresh _ time/UI _ chase _ refresh _ time = [ (Real _ SOC + K)/(UI _ SOC + K) ], a catch-up refresh period UI _ chase _ refresh _ time can be calculated; the refresh period UI _ refresh _ time is updated by the refresh catch-up period UI _ chase _ refresh _ time, that is, the refresh catch-up period UI _ chase _ refresh _ time replaces the calculated refresh period UI _ refresh _ time to refresh the electric quantity display, so that unnecessary refresh operations can be avoided, and the final display result of the charging state can be ensured to be correct.

The values of the two weights K1 and K2 may be empirical values, such as K1=3, K2=20%; but is not limited thereto. In practical application, if K1 × Diff _ SOC + K2 × remaining _ SOC is too large, the remaining _ SOC is used as the upper limit of the influence factor K, so as to avoid that the influence factor K has too large influence on the ratio of the proportional formula, which results in invalid adjustment.

For example, real _ SOC =80%, UI _ SOC =70%, when: diff _ SOC =80% -70% =10%, remain _ SOC =100% -80% =20%,3 + Diff _soc +20% + Remain _ SOC =3 + 10% +20% =34%, then K = Remain _ SOC =20%; then, the refresh chasing period calculated by the electric quantity refresh algorithm module is specifically as follows: UI _ chase _ refresh _ time = UI _ refresh _ time/[ (80% + 20%)/(70% + 20%) ] = UI _ refresh _ time/1.111. That is, at this time, the refresh cycle can be reduced, and the refresh rate can be increased, so that the UI power can catch up with the real power as soon as possible.

That is, for the electric quantity change interval represented by the influence factor K, the UI electric quantity needs to catch up with the real electric quantity; for example, the value of UI _ chase _ refresh _ time may be no less than 5s, and the magnitude of the charge increase may be no more than 1% within 5s.

Example two: the actual charge is less than the UI charge and the battery is charging.

At the moment, the UI electric quantity is ahead of the Real electric quantity, and the specific difference value Diff _ SOC = | Real _ SOC-UI _ SOC |; taking Real _ SOC =80%, UI _ SOC =90%, K1=3, and K2=20% as an example, the following are given: diff _ SOC =10%, remain _ SOC =100% -80% =20%,3 + Diff _ SOC +20% + Remain _ SOC =3 + 10% +20% =34%, then K = Remain _ SOC =20%; then, the refresh chasing period calculated by the electric quantity refresh algorithm module is specifically as follows: UI _ chase _ refresh _ time = UI _ refresh _ time/[ (80% + 20%)/(90% + 20%) ] = UI _ refresh _ time/0.909. That is, at this time, the refresh rate may be slowed down, and the difference value Diff _ SOC between the UI power amount and the actual power amount may be reduced to bring the UI power amount and the actual power amount closer to each other.

Example three: the true charge is greater than the UI charge and the battery is discharging.

At the moment, the UI electric quantity lags behind the Real electric quantity, and the specific difference value Diff _ SOC = | Real _ SOC-UI _ SOC |; still taking the example of Real _ SOC =80%, UI _ SOC =70%, K1=3, and K2=20%, then: diff _ SOC =10%, remain _ SOC =100% -80% =20%,3 + Diff _ SOC +20% + Remain _ SOC =3 + 10% +20% =34%, then K = Remain _ SOC =20%; since the refresh rate should be slowed down, that is, the refresh period should be increased, the proportional relationship of the above proportional formula is exchanged to obtain a proportional formula applicable to the discharge state, which is specifically UI _ chase _ refresh _ time = UI _ refresh _ time/[ (UI _ SOC + K)/(Real _ SOC + K) ]; the refresh catch-up period is obtained as follows: UI _ chase _ refresh _ time = UI _ refresh _ time/[ (70% + 20%)/(80% + 20%) ] = UI _ refresh _ time/0.9, thereby enabling incremental adjustments and updates to the refresh period.

Example four: the true power is less than the UI power and the battery is discharging.

At the moment, the UI electric quantity is ahead of the Real electric quantity, and the specific difference value Diff _ SOC = | Real _ SOC-UI _ SOC |; still taking Real _ SOC =80%, UI _ SOC =90%, K1=3, and K2=20% as examples, then: diff _ SOC =10%, remain _ SOC =100% -80% =20%,3 + Diff _ SOC +20% + Remain _ SOC =3 + 10% +20% =34%, then K = Remain _ SOC =20%; the refresh pursuit period is calculated by adopting a proportional formula in a discharge state and is specifically as follows: UI _ chase _ refresh _ time = UI _ refresh _ time/[ (90% + 20%)/(80% + 20%) ] = UI _ refresh _ time/1.1, thereby enabling reduced adjustments and updates for the refresh period.

After the real electric quantity of the battery is obtained through calculation, the electric quantity refreshing module can timely, smoothly and non-jump refresh and display the UI electric quantity according to the refreshing cycle by the real electric quantity, and can eliminate the difference value between the UI electric quantity and the real electric quantity within a certain interval range.

As can be obtained from the above, the method for displaying battery power as shown in fig. 6 specifically includes: step S0 performed by the fuel gauge, and steps S1 to S4 performed by the processor. Wherein, each step is respectively:

and S0, collecting the current of the battery, and calculating to obtain the coulomb value.

After the coulometer obtains the current and coulomb value, the current can pass through I ² The interface C transmits the data to a fuel gauge driver of a kernel layer of the processor; then, the electricity quantity refreshing module of the charge and discharge service of the inner core layer reads the coulomb value from the electricity meter drive, and the newly added electricity quantity refreshing algorithm module in the charge and discharge service reads the current from the electricity meter drive.

S1, determining the real electric quantity of the battery according to the coulomb value of the battery.

This step is specifically executed by the power refreshing module, and the specific process thereof can be referred to the foregoing content, which is not described herein again.

And S2, determining a refresh period corresponding to the current according to the current of the battery.

The step is specifically realized by an electric quantity refreshing algorithm module, and the execution sequence of the step and the step S1 is not limited, and the step S can be executed simultaneously; in addition, a specific example is that before step S2 is executed, the electric quantity refreshing algorithm module performs abnormality screening on a plurality of continuous sampling values of the battery current, and if the plurality of continuous sampling values are not abnormal, an average value of the plurality of continuous sampling values is used as the current I used for calculating the refreshing period _Rsense . For example, in the case of a liquid,the sampling value can be read 5 times every 5ms, the current cannot suddenly change according to Lenz's law, so the maximum value and the minimum value can be selected, if the difference value between the maximum value and the minimum value is larger than a preset threshold Cur _ Diff _ Thld, such as 20mA, the sampling value can be actually optimized according to the actual measurement condition, the sampling value is abnormal, such as hardware fault or I ² And C, if the sampling value is abnormal when the communication is abnormal, discarding the group of data, repeatedly executing the sampling and the screening process, and executing the step S2 after obtaining the sampling result without abnormality.

For the refresh period UI _ refresh _ time and current I _Rsense A specific example is I _Rsense ∈(0,0.5]UI _ refresh _ time =20s; i is _Rsense ∈(0.5,1]UI _ refresh _ time =15s; i is _Rsense ∈(1,2]UI _ refresh _ time =10s; i is _Rsense ∈(2,4]When UI _ refresh _ time =5s. This is merely an example and is not limited thereto, for example, as mentioned above, the refresh period may be specifically inversely proportional to the absolute value of the current; at this time, the specific process of step S2 includes the process shown in fig. 6:

and S21, determining unit capacity represented by the minimum display unit of the UI electric quantity according to the display precision of the UI electric quantity.

Taking the display accuracy of the UI power as 1%, at this time, the minimum display unit is also 1%, that is, if the real power is changed from 80.15% to 80.75% during the refresh, the UI power does not need to be refreshed this time, and is still displayed as 80%. When the total capacity of the battery is C, the unit capacity represented by the minimum display unit is C/100.

And S22, determining the time required for the current to reach the unit capacity as a refresh period.

At its simplest, the refresh period may adopt the aforementioned formula UI _ refresh _ time = C/100/| I _Rsense I, calculating; wherein UI _ refresh _ time is the calculation of refresh period, C is the total capacity of the battery, I _Rsense Is the current.

After the refresh period UI _ refresh _ time is obtained, the UI _ refresh _ time can be directly reported to an electric quantity refresh module, the electric quantity refresh module executes the step S4, at the moment, the UI electric quantity can be refreshed timely, the electric quantity rising amplitude can be ensured not to be larger than 1% in a single time range of the refresh period UI _ refresh _ time, and smooth display without jumping is ensured; or, the electric quantity refreshing algorithm module may perform step S3 first, that is, further adjust and update the electric quantity, and report the electric quantity to the electric quantity refreshing module, and the electric quantity refreshing module performs step S4.

And S3, updating the refreshing cycle by taking the UI electric quantity equal to the real electric quantity as a target before the real electric quantity reaches the charge-discharge limit value of the battery.

At the latest when the real electric quantity reaches the charge-discharge limit value of the battery, the UI electric quantity can be equal to the real electric quantity, namely the goal is realized. Specifically, step S3 includes the steps shown in fig. 6:

and S31, determining a catch-up refresh period required to be adopted for realizing the target according to the running state of the battery.

As mentioned above, when the battery is in different operating states, the proportional formula for calculating the catch-up refresh period UI _ chase _ refresh _ time may be different, specifically: if the running state of the battery is the charging state, calculating to obtain a catching up refreshing period proportion formula as UI _ refresh _ time/UI _ chase _ refresh _ time = [ (Real _ SOC + K)/(UI _ SOC + K) ]; if the running state of the battery is a discharging state, calculating to obtain a proportional formula of the catching up refreshing period, namely UI _ refresh _ time/UI _ chase _ refresh _ time = [ (UI _ SOC + K)/(Real _ SOC + K) ]; the Real _ SOC is Real electric quantity, the UI _ SOC is UI electric quantity, the UI _ refresh _ time is refresh time, the UI _ chase _ refresh _ time is a catch-up refresh period, and K is a preset value.

The specific value of the preset value K has two conditions, and the specific calculation formula is as follows:

wherein, diff _ SOC = | Real _ SOC-UI _ SOC |, the remaining _ SOC is an absolute value of a difference between a Real electric quantity and a charging and discharging limit value in a corresponding operation state, the remaining _ SOC = |100% -Real _ SOC | in the charging state, and the remaining _ SOC = |0% -Real _ SOC | in the discharging state.

For the values of the two weights K1 and K2, reference may be made to the above, but the values are not limited to the above, and may vary depending on the specific application environment, and are within the scope of the present application.

And S32, updating the refresh period by the chasing refresh period.

That is, the refresh time UI _ refresh _ time calculated in step S2 is updated with the catch-up refresh period UI _ chase _ refresh _ time, and step S4 is executed.

And S4, refreshing and displaying the UI electric quantity with the real electric quantity according to a refreshing cycle.

s101, determining the real electric quantity of the battery according to the coulomb value of the battery in the electronic equipment.

In a specific example, before step S102, the method further includes:
