Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs. The terms used herein in the specification of the application are for the purpose of describing specific embodiments only, and are not intended to limit the application.

The existing power display method is based on a certain adjustment rate, for example, every preset time period, the displayed power changes by 1%, so that the displayed power gradually approaches the actual power. The existing power display method is more suitable for scenarios where the working conditions change smoothly or the average discharge rate is low, but it is not suitable for the scene where the working conditions change greatly and the discharge rate is high. This is because: if the adjustment rate is set small, the displayed power will appear to change too slowly under high power consumption, so that it cannot keep up, and eventually lead to sudden changes in power, which will make it too late for the user to prepare for the end and use the drone For example, a sudden change in the power level will make it too late for the user to prepare for the return flight; if the adjustment rate is set to a large value, the displayed power level will appear to change too fast under low power consumption, which will make the user feel that the electronic device is not used much, and the battery power will decrease is still faster. It can be seen that the user experience is not good if the power changes suddenly or changes too fast.

In order to solve the above problem, an embodiment of the present application proposes a new power display method, so that the actual power estimated in real time is filtered and then displayed to the user, so that the displayed battery power can be smoothly synchronized with the actual battery power of the battery , to improve the user experience.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

FIG. 1 is a schematic flowchart of a power display method provided by an embodiment of the present application. The execution body of the method provided by the embodiments of the present application may be any device that needs to be powered by a battery, such as a drone, an electric vehicle, a mobile phone, a notebook computer, a tablet computer, and so on. As shown in Figure 1, the method includes:

101. Determine the actual power change amount currently corresponding to the battery.

102. Obtain an update coefficient.

The update coefficient is used to represent the ratio of the expected change rate of the displayed power corresponding to the battery to the change rate of the actual power corresponding to the battery.

103. Update the displayed power level corresponding to the battery according to the update coefficient and the actual power change amount.

In the above 101, the variation of the actual electric power corresponding to the battery currently refers to the difference between the current estimated value of the actual electric power corresponding to the battery and the last estimated value.

In an achievable solution, the current actual amount of change in battery power corresponding to the battery can be estimated by using the ampere-hour integration method. For the estimation process of the ampere-hour integration method, reference may be made to the prior art, which will not be described in detail here.

Among them, the power can be represented by the state of charge (SOC) of the battery.

In the above 102, in an example, the above update coefficient may be a set value, and the specific size may be set according to actual needs, which is not specifically limited in this embodiment of the present application. In another example, the above-mentioned update coefficient can be obtained by real-time calculation according to the current actual situation of the battery, and the specific implementation method will be described in detail in the following embodiments.

In the above 103, the update amount corresponding to the displayed power level may be determined according to the update coefficient and the actual power change amount; according to the update amount, the displayed power level corresponding to the battery is updated. Specifically, the product of the update coefficient and the actual power change amount can be used as the update amount.

In the technical solutions provided by the embodiments of the present application, when the currently displayed displayed power is updated, the current actual power change corresponding to the battery is considered. The current actual power change corresponding to the battery reflects the current charge/discharge rate of the battery, that is to say, the technical solutions provided by the embodiments of the present application can combine the current charge/discharge rate of the battery to adjust each update amount of the displayed power in real time, In this way, problems such as too fast or sudden change of the display power caused by improper setting of the update amount are avoided, so that the displayed battery power can be smoothly synchronized with the actual battery power of the battery, and the user experience is improved.

In an achievable solution, the “obtaining the update coefficient” in the above 102 may be implemented by the following steps:

1021. Determine the current estimated value of the actual power corresponding to the battery.

1022. Determine an expected value that the actual power level and the displayed power level reach at the same time.

1023. Determine, according to the current displayed value of the displayed power, the current estimated value, and the expected value, a ratio of the expected rate of change of the displayed power to the rate of change of the actual power, as the update coefficient.

In the above 1021, the last estimated value of the actual power corresponding to the battery can be obtained; according to the last estimated value and the current change of the actual power corresponding to the battery, the current estimated value of the actual power corresponding to the battery is determined .

In the above-mentioned 1022, in one example, the above-mentioned expected value may be a set value. In order to prevent the calculated update coefficient from being too large or too small, the above-mentioned expected value can be set to be greater than or equal to the first preset threshold and less than or equal to the second preset threshold; the second preset threshold is greater than the first preset threshold, The first preset threshold is greater than 0. The sizes of the first preset threshold and the second preset threshold may be set according to actual needs, which are not specifically limited in this embodiment of the present application. For example, during battery discharge, the first preset threshold is 10% and the second preset threshold is 30%; during battery charging, the first preset threshold is 70% and the second preset threshold is 90%.

In another example, in the above 1022, "determine the expected value that the actual power level and the displayed power level reach at the same time", specifically:

S11. Determine, according to the current estimated value, an expected value that the actual electric quantity and the displayed electric quantity reach at the same time.

In the above S11, during the discharging process of the battery, a first preset difference value may be obtained, and the expected value is obtained by subtracting the first preset difference value from the current estimated value of the actual power corresponding to the battery. During the battery charging process, a second preset difference value may be obtained, and the expected value is obtained by adding the second preset difference value to the current estimated value of the actual power corresponding to the battery.

The sizes of the first preset difference and the second preset difference can be set according to actual needs, which are not specifically limited in this embodiment of the present application, for example: the first preset difference and the first preset difference The two preset difference values can be set to 30%.

The expected value obtained in this way is more reasonable and more in line with the current actual situation of the battery.

In the above 1023, the first difference between the current display value and the expected value of the displayed power is calculated; the second difference between the current estimated value and the expected value is calculated; the ratio of the first difference to the second difference is The ratio of the expected rate of change of the displayed power to the rate of change of the actual power.

In order to facilitate the understanding of the technical solutions provided by the embodiments of the present application, the following description will be made with reference to FIG. 2 . Wherein, the horizontal axis of the coordinate system in FIG. 2 is the time axis, and the vertical axis is the electric quantity axis. The abscissa coordinate of the origin O of the coordinate system in Fig. 2 represents the current moment; the ordinate coordinate of point A represents the current display value SOC _s of the display power corresponding to the battery; the ordinate coordinate of point B represents the current estimation of the actual power corresponding to the battery The value of SOC _r ; the horizontal axis of point C represents the time when the displayed power corresponding to the battery is synchronized to the actual power at the latest. The ordinate of point F represents the above-mentioned desired value SOC _f . Among them, the slope k _AF of the straight line AF is also the expected change rate of the displayed electric quantity; the slope k _BF of the straight line BF is also the change rate of the actual electric quantity. Therefore, the calculation formula of the update coefficient K1 is:

Note: For ease of understanding, the slope k _BF of the straight line BF can be normalized to 1, then the update coefficient K1 is also the slope k _{AF of the straight line AF} .

Using the technical solutions provided by the embodiments of the present application can ensure that the displayed power is synchronized to the actual power before the actual power of the battery is exhausted, and there is no problem of sudden changes in power. In order to make the displayed value of the displayed power as close as possible to the estimated value of the actual power during the entire discharging or charging process of the battery, and to prevent the displayed power from changing too quickly, upper and lower limits can be set for the expected value, that is, the expected value is set to be greater than or equal to The first preset threshold is smaller than or equal to the second preset threshold; the second preset threshold is greater than the first preset threshold; the first preset threshold is greater than 0.

As we all know, when the discharge cut-off condition is certain, the actual dischargeable capacity of the battery is affected by the real-time working conditions (such as temperature, discharge rate, etc.) and the aging state of the battery (capacity, internal resistance). Therefore, the power that the user cares about is not based on the remaining power estimated by the ampere-hour integration method, but is based on the remaining power under the current operating conditions. Therefore, in the above-mentioned 101, "determining the actual amount of change of the battery's current corresponding power" can be implemented by the following steps:

1011. Use the ampere-hour integration method to perform a preliminary estimation on the actual power change corresponding to the battery currently, to obtain an initial actual power change.

1012. Correct the initial actual power change amount according to the operating condition data and/or aging data of the battery to obtain the corrected actual power change amount.

1013. Determine, according to the corrected actual power change amount, a current actual power change amount corresponding to the battery.

In the above 1012, the working condition data includes: battery temperature and/or battery discharge rate. The aging data includes: battery capacity and/or battery internal resistance. Specifically, the correction coefficient may be determined according to the operating condition data and/or aging data of the battery; the product of the correction coefficient and the initial actual current change amount is taken as the corrected actual current change amount. The process of determining the correction coefficient according to the operating condition data and/or the aging data of the battery may refer to the prior art, which will not be described in detail here.

In the above 1013, in an example, the actual power change amount after the correction can be directly used as the actual power change amount corresponding to the battery currently.

In another example, product definitions such as: capacity concealment, temperature compensation, etc. are considered. Capacity hiding refers to the partial capacity of the battery. For example, 10% is hidden and cannot be used by the user. Therefore, it is necessary to map the actual capacity of the battery in the range of 10% to 100% to the range of 0 to 100%. Consider temperature compensation, that is, take into account the effect of temperature on the actual power of the battery. Therefore, in the above 1013, "determine the actual power change corresponding to the battery currently according to the corrected actual power change", specifically: map the corrected actual power change to obtain the current corresponding battery the actual power change. In practical application, the mapping coefficient can be obtained; the product of the mapping coefficient and the corrected actual power change amount is taken as the current corresponding actual power change amount of the battery. The above mapping coefficients are related to capacity concealment and/or temperature compensation.

In the above embodiment, the influence of temperature, charge/discharge rate, battery aging state, and product definition is fully considered, which is more suitable for the actual use scenario of the user.

In an example, the upper and lower limits of the above-mentioned update coefficients can also be set. That is, in the above 103, "update the displayed power level corresponding to the battery according to the update coefficient and the actual power change amount" may specifically include the following step 1031a and/or the following step 1032a.

1031a. When the update coefficient is greater than the first upper limit value of the first preset value range, update the displayed power level corresponding to the battery according to the first upper limit value and the actual power change amount.

1032a. When the update coefficient is smaller than the first lower limit value of the first preset value range, update the displayed power level corresponding to the battery according to the first lower limit value and the actual power change amount.

In the above 1031, the product of the first upper limit value and the actual power change amount may be used as the update amount; the displayed power level corresponding to the battery is updated according to the update amount.

In the above 1032, the product of the first lower limit value and the actual power change amount may be used as the update amount; the displayed power level corresponding to the battery is updated according to the update amount.

In another example, upper and lower limits of the update amount may also be set. Specifically, in the above 103, "update the displayed power level corresponding to the battery according to the update coefficient and the actual power change amount", which may specifically include the following step 1031b and the following step 1032b and/or the following steps 1032a.

1031b. Determine an update amount according to the update coefficient and the actual power change amount.

1032b. When the update amount is greater than the second upper limit value of the second preset value range, update the displayed power level corresponding to the battery according to the second upper limit value.

1033b. When the update amount is less than the second lower limit value of the second preset value range, update the displayed power level corresponding to the battery according to the second lower limit value.

In the above 1031b, the product of the update coefficient and the actual power change amount may be used as the update amount.

In the above-mentioned 1032b, the displayed power level is updated using the second upper limit value as the actual update amount.

In the above-mentioned 1033b, the displayed power level is updated using the second lower limit value as the actual update amount.

The technical solution provided by the embodiment itself will be described in detail below in conjunction with Fig. 3:

Step 201 , collecting signals, such as battery current and battery working condition.

Step 202 , using the ampere-hour integration method to estimate the initial actual power change.

Step 203 , acquiring the battery aging state.

Step 204 , correcting the initial actual power change.

Step 205: Map the actual power change after the correction to obtain the actual power change.

Step 206: Determine the current estimated value of the actual power according to the variation of the actual power.

Step 207: Calculate the update coefficient K1 according to the current estimated value of the actual power, the current displayed value of the displayed power, and the expected value.

Wherein, the size of the expected value is determined by the current estimated value of the actual power, and specifically, the expected value is obtained by subtracting 30% from the current estimated value.

Step 208: Determine the update amount according to the update coefficient K1 and the actual amount of electricity change.

Step 209: Update the displayed power according to the update amount.

Using the technical solutions provided by the embodiments of the present application can make the display of the power of the battery smoother and linear, and provide a more friendly user experience.
