[0079] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0080] The parameters for calculating the usable time of the battery include: the remaining battery power R M and the predicted subsequent discharge power P M , the battery life is: t = R M / P M .

[0081] Remaining power R MIt is obtained by the simulation of the fuel gauge. Since the internal resistance of lithium batteries is higher when RSOC (Relative State Of Charge) is lower, that is, when RSOC is lower, the greater the load, the lower the battery output voltage. If the battery voltage drops to the system shutdown voltage of 3.4V under normal load, it can be switched to a smaller load than the normal load. At this time, the battery voltage will rebound slightly, and the voltage rebound will provide the system with longer additional battery life. For example, see Figure 1 The schematic diagram of the capacity corresponding to different cut-off voltages and different discharge currents in a low temperature environment is shown, or refer to Figure 2 The schematic diagram of the capacity corresponding to different cut-off voltages and different discharge currents in a normal temperature environment is shown. In a low temperature or normal temperature environment, at the same cut-off voltage, the smaller the discharge current (i.e., the lower the discharge power, the smaller the load), the larger the capacity that can be discharged by the battery (i.e., the more remaining power), and the longer the battery can be used. Moreover, at the same discharge current, the smaller the cut-off voltage, the larger the capacity that can be discharged by the battery, and the longer the battery can be used. In other words, in the final discharge stage, the lower the discharge power, the more remaining power the battery can discharge, and when switching from a larger load to a smaller load, the battery voltage will rebound.

[0082] In the related art, the power meter calculates the remaining power R M The method is: simulate according to the average discharge power of the first 4% of the power, the first 4% of the power refers to the 4% of the power before the current visible power, for example, the current visible power is 20, and the first 4% of the power is 20%-24%. However, when the power is low, most users will stop high-power loads (such as playing games, video chatting, etc.), and the lower the power, the more afraid the user is to shut down, and the frequency of using electronic devices will be lower; when the BCL (Battery Current Limit) mode is turned on, that is, the power saving mode is turned on, the lower the power, the lower the limited power usage. Therefore, using the average discharge power of the first 4% of the power to simulate the remaining power will result in a smaller simulated remaining power, which will result in a smaller calculated battery usable time.

[0083] Discharge power P M It is the predicted average discharge power in the next period. Currently, it uses the average discharge power in the previous period, and does not take into account the changes in user usage under low power and the BCL strategy. Therefore, the discharge power is too large, resulting in a shorter calculated battery life.

[0084] To sum up, in the related technology, the remaining power is too small and the discharge power is too large, so the calculated available battery life is too long and inaccurate. When the available time is displayed to the user, the user receives an erroneous available time, which affects the user's usage experience.

[0085] In response to the above-mentioned problems, the embodiments of the present disclosure take into account the user's usage habits and determine the discharge parameters and the remaining power to more accurately represent the battery usage under the remaining power, thereby determining the battery's available time more accurately, thereby improving the accuracy of the available time. When the available time is displayed to the user, the user can understand the more accurate available time, thereby improving the user experience.

[0086] The method for displaying the available battery life provided by the embodiment of the present disclosure is executed by an electronic device, which may be a mobile phone, a tablet computer, a laptop computer, a wearable device, a smart home device, or other device that includes a battery.

[0087] In the embodiment of the present disclosure, in response to the visible power level of the battery being lower than a preset threshold, the electronic device displays the available time of the battery, wherein the available time is determined based on the current remaining power level of the battery and the discharge parameter, and the discharge parameter is determined based on the historical usage data of the battery, and the historical usage data is used to characterize the historical discharge parameters of the battery at different visible power levels during the historical use of the battery.

[0088] Under the same visible power level, the battery usage this time is likely to be similar to the usage in the previous historical usage process. Then, the discharge parameters determined based on the historical usage data can more accurately represent the next discharge parameters. Therefore, compared with the related art, the average value of the discharge power in the previous period is taken as the next discharge parameter, and the discharge parameters determined based on the historical usage data are obviously more accurate. For the remaining power of the battery, the remaining power is simulated based on the discharge parameters, wherein the simulated remaining power will be different for different discharge parameters. Therefore, when more accurate discharge parameters are obtained, the simulated remaining power will also be more accurate. Therefore, after determining the accurate discharge parameters and remaining power, the available time determined based on the remaining power and discharge parameters is also more accurate. When the available time is displayed to the user, the user can understand the more accurate available time, which improves the user experience.

[0089] The process of determining the available time and displaying the available time is described in detail below through the following embodiments.

[0090] Figure 3 is a flow chart showing a method for displaying the available battery life according to an exemplary embodiment, which is executed by an electronic device, see Figure 3 , the method comprises the following steps:

[0091] Step S301 , in response to the visible power level of the battery being lower than a preset power level, a discharge parameter of the battery is determined based on historical usage data of the battery.

[0092] The visible power level of the battery is the power level displayed to the user, and the preset threshold is a preset value, for example, the preset threshold is 40%, 30%, 20%, etc. Optionally, the user may be more concerned about the available battery life when the battery is low, so the preset threshold can be set to a smaller value, so that when the battery is low, the available battery life is determined in the manner provided by the embodiment of the present disclosure, so that the user receives a more accurate available battery life.

[0093] In the embodiment of the present disclosure, considering that the discharge parameters of the battery are different in different operating modes, the corresponding discharge parameters are obtained for the operating mode the battery is currently in. Optionally, the operating mode is divided into a first operating mode and a second operating mode, the first operating mode may also be referred to as a non-power saving mode, and the second operating mode may also be referred to as a power saving mode, wherein the power saving mode refers to a mode for saving the battery power by limiting the discharge current or discharge power, and the non-power saving mode does not limit the discharge current or discharge power. Among them, the discharge parameter is the discharge current or discharge power.

[0094] In some embodiments, in the first operating mode, the discharge parameter determined based on the historical usage data is directly used as the discharge parameter of the battery. In the second operating mode, an upper limit discharge parameter is set. If the discharge determined based on the historical usage data is greater than the upper limit discharge parameter, the upper limit discharge parameter is used as the discharge parameter of the battery. If the discharge parameter determined based on the historical usage data is less than or equal to the upper limit discharge parameter, the discharge parameter determined based on the historical usage data is used as the discharge parameter of the battery.

[0095] Step S302: determining the current remaining power of the battery based on the discharge parameters.

[0096] Step S303, determining the usable time of the battery according to the discharge parameters and the remaining power.

[0097] The usable time of the battery is determined based on the ratio of the remaining power to the discharge parameter.

[0098] Step S304, displaying the available time.

[0099] The method provided by the embodiment of the present disclosure determines the discharge parameters based on the historical usage data of the battery, takes into account the user's usage habits, and more accurately represents the usage of the battery under the remaining power, so that the determined available battery life is more accurate. When the available time is displayed to the user, the user can understand the more accurate available time, thereby improving the user experience.

[0100] In some embodiments, in different operating modes, different methods are used to determine the discharge parameters corresponding to the battery.

[0101] Figure 4 is a flow chart showing another method for displaying the available battery life according to an exemplary embodiment, which is executed by an electronic device, see Figure 4 , the method comprises the following steps:

[0102] Step S401 , in response to the visible power level of the battery being lower than a preset threshold, determining the operating mode of the battery.

[0103] The operating mode of the battery is the first operating mode or the second operating mode.

[0104] In some embodiments, when it is detected that the power saving mode is turned on, it is determined that the battery is in the second operating mode, and when it is detected that the power saving mode is not turned on, it is determined that the battery is in the first operating mode.

[0105] When the battery is in the first operating mode, step S402 is executed, and when the battery is in the second operating mode, step S403 is executed.

[0106] Step S402: in response to the battery being in the first operation mode, determining an average value of M historical discharge parameters in the historical usage data as a discharge parameter of the battery.

[0107] In some embodiments, the average value of M historical discharge parameters in the historical usage data is determined as the discharge parameter; wherein M is greater than or equal to 1, and the M historical discharge parameters are historical discharge parameters for each historical visible power in the first power range, and the upper limit value of the first power range is the current visible power of the battery, and the lower limit value is the preset power. In other words, the historical discharge parameters of the battery under the same historical visible power as the current visible power and the subsequent historical visible power in the historical usage data are obtained, wherein the historical discharge parameters under different historical visible powers may be the same or different. Wherein, the preset power is 0%.

[0108] Optionally, taking into account that the historical discharge parameters may suddenly increase or decrease during historical use, when determining the discharge parameters, M+2 historical discharge parameters are obtained, and then the maximum and minimum values ​​of the M+2 historical discharge parameters are removed, and then the remaining M historical discharge parameters are averaged to obtain the discharge parameters.

[0109] In some embodiments, historical usage data of the battery is obtained for L times, and for each historical usage data, the corresponding average values ​​of M historical discharge parameters are obtained respectively, and then the L average values ​​are averaged to obtain the discharge parameter. Optionally, considering that the historical discharge parameter may suddenly increase or decrease during the historical usage process, when determining the discharge parameter, L+2 historical usage data are obtained, and then the average value of the M historical discharge parameters corresponding to each historical usage data is determined, and then the maximum and minimum values ​​of the L+2 average values ​​are removed, and then the remaining L average values ​​are averaged to obtain the discharge parameter.

[0110] Step S403, in response to the battery being in the second operating mode, determining an average value of M historical discharge parameters in the historical usage data, and determining a discharge parameter of the battery according to the average value of the M historical discharge parameters and an upper limit discharge parameter in the second operating mode.

[0111] The process of determining the average values ​​of the M historical discharge parameters refers to the above step S402 and will not be described in detail here.

[0112] In some embodiments, the discharge parameter of the battery is determined according to the average value of M historical discharge parameters and the upper limit discharge parameter in the second operating mode, including: when the average value of the M historical discharge parameters is less than or equal to the upper limit discharge parameter in the second operating mode, the average value of the M historical discharge parameters is determined as the discharge parameter; when the average value of the M historical discharge parameters is greater than the upper limit discharge parameter, the upper limit discharge parameter is determined as the discharge parameter. In other words, the minimum value of the average value of the M historical discharge parameters and the upper limit discharge parameter is determined as the discharge parameter of the battery in the second operating mode, thereby ensuring that the discharge parameter is as small as possible in the second operating mode, so as to increase the usable time of the battery as much as possible.

[0113] Step S404: determining the current remaining power of the battery based on the discharge parameters.

[0114] In some embodiments, a current remaining capacity of the battery is obtained by simulating the discharge parameters through a power meter.

[0115] Step S405, determining the usable time of the battery according to the discharge parameters and the remaining power.

[0116] The ratio of the remaining power to the discharge parameter is used to determine the usable time of the battery.

[0117] Step S406, displaying the available time.

[0118] After the available time is obtained, the available time is displayed so that the user can check the available time to understand the battery usage.

[0119] It should be noted that, in some embodiments, when the visible power of the battery is less than or equal to a preset threshold, the discharge parameter corresponding to the mode in which the battery is located is obtained. That is, first determine whether the current visible power of the battery is less than or equal to the preset threshold, if the visible power is less than or equal to the preset threshold, then start to execute the above step S401, if the visible power is greater than the preset threshold, then do not execute the above step. The preset threshold is a preset value.

[0120] Optionally, when the battery level is high, the user does not worry about insufficient available time, but when the battery level is low, the user will pay more attention to the available battery time and hope that the available battery time is more accurate. Therefore, when the battery level is low, the available time can be determined using the method provided in the embodiment of the present disclosure, so that the preset threshold can be a smaller value, for example, the preset threshold is a smaller value such as 25%, 20%, 15%, etc.

[0121] In the method provided by the embodiment of the present disclosure, the discharge parameter is determined based on the user's historical usage or the upper limit discharge parameter in the second operating mode, taking into account the user's usage habits and the operating mode of the battery. The corresponding discharge parameters are used in different operating modes, which can more accurately represent the usage of the battery under the remaining power, so that the available time of the battery determined based on the discharge parameter and the remaining power is also more accurate, thereby improving the accuracy of the available time and enhancing the user experience.

[0122] In one example, Figure 4 The embodiment shown can be Figure 5 As shown, taking the preset threshold of 20% as an example, see Figure 5 , including the following steps:

[0123] 1. Make sure the visible power level of the electronic device is less than or equal to 20%.

[0124] 2. Determine whether the power saving mode is turned on. If the power saving mode is not turned on, go to step 3. If the power saving mode is turned on, go to step 4.

[0125] 3. Based on the historical usage data, determine the average value of M historical discharge parameters, and based on the average value of the M historical discharge parameters, determine the usable time of the battery.

[0126] The implementation of step 3 refers to the above steps S402 and S404-S405, which will not be repeated here.

[0127] 4. Based on the historical usage data, determine the average value of M historical discharge parameters, and obtain the upper limit discharge parameter in the power saving mode. Based on the average value of the M historical discharge parameters and the upper limit discharge parameter, determine the usable time of the battery.

[0128] The implementation of step 4 refers to the above steps S403-S405, which will not be described in detail here.

[0129] 5. Display the available time.

[0130] In some embodiments, the discharge parameters may be different within different power ranges. For example, when the visible power level of the battery is low, the user will try to reduce its usage as much as possible. That is, the higher the visible power level in the power range, the larger the discharge parameter, and the lower the visible power level in the power range, the smaller the discharge parameter. Therefore, in order to make the determined available time more accurate, corresponding discharge parameters are determined for each power range.

[0131] Figure 6 is a flow chart showing another method for displaying the available battery life according to an exemplary embodiment, which is executed by an electronic device, see Figure 6 , the method comprises the following steps:

[0132] Step S601 , in response to the visible power level of the battery being lower than a preset threshold, determining the operating mode of the battery.

[0133] The implementation of step S601 refers to the above step S401 and will not be described in detail here.

[0134] Step S602 , in response to the battery being in the first operating mode, for each second power range, an average value of K historical discharge parameters corresponding to the second power range in the historical usage data is determined as a discharge parameter.

[0135] In some embodiments, the current visible power of the battery corresponds to N second power ranges, where N is greater than or equal to 1, and the upper limit value of the N second power ranges is the current visible power of the battery, and the lower limit value is the preset power. For each second power range, the average value of the K historical discharge parameters corresponding to the second power range in the historical usage data is determined as the discharge parameter of the second power range; where K is greater than or equal to 1. That is, the discharge parameters of the battery include the discharge parameters of the N second power ranges.

[0136] Optionally, taking into account the possibility that historical discharge parameters may suddenly increase or decrease during historical use, for each second power range, when determining the discharge parameters of the second power range, N+2 historical discharge parameters corresponding to the second power range are obtained, and then the maximum and minimum values ​​of the N+2 historical discharge parameters are removed, and then the remaining N historical discharge parameters are averaged to obtain the discharge parameters of the second power range.

[0137] In some embodiments, historical usage data of the battery is obtained for L times, and for each historical usage data, the average value of N historical discharge parameters corresponding to each second power range is obtained respectively, and then the L average values ​​are averaged to obtain the discharge parameters of the second power range. Optionally, considering that the historical discharge parameters may suddenly increase or decrease during the historical use process, for each second power range, when determining the discharge parameters of the second power range, L+2 historical usage data are obtained, and then the average value of N historical discharge parameters corresponding to each historical usage data is determined, and then the maximum and minimum values ​​of the L+2 average values ​​are removed, and then the remaining L average values ​​are averaged to obtain the discharge parameters of the second power range.

[0138] In some embodiments, N second power ranges are divided according to preset rules and the current visible power of the battery. The preset rule is to evenly divide the current visible power into N second power ranges, for example, if the current visible power is 20%, it can be divided into four power ranges of 20%-15%, 15%-10%, 10%-5% and 5-0%; or the current visible power is divided into N second power ranges in descending order, that is, the N second power ranges obtained by division are descending in order, for example, if the current visible power is 20%, it can be divided into four power ranges of 20%-5%, 5%-3%, 3%-1% and 0%.

[0139] Step S603, in response to the battery being in the second operating mode, for each second power range, determine the average value of K historical discharge parameters corresponding to the second power range in the historical usage data, and determine the discharge parameter based on the average value of the K historical discharge parameters and the corresponding upper limit discharge parameter.

[0140] The process of determining the average values ​​of the K historical discharge parameters is as described in the above step S602, which will not be described in detail here. The current visible power of the battery corresponds to N second power ranges.

[0141] In some embodiments, for each second power range, when the average value of the K historical discharge parameters corresponding to the second power range is less than or equal to the corresponding upper limit discharge parameter, the average value of the K historical discharge parameters is determined as the discharge parameter of the second power range; or, when the average value of the K historical discharge parameters corresponding to the second power range is greater than the corresponding upper limit discharge parameter, the upper limit discharge parameter is determined as the discharge parameter of the second power range. That is to say, for each second power range, the minimum value of the average value of the K historical discharge parameters corresponding to the second power range and the corresponding upper limit discharge parameter is determined as the discharge parameter of the second power range in the second operating mode, thereby ensuring that in the second operating mode, the discharge parameter is as small as possible, so that the usable time of the battery is increased as much as possible.

[0142] Step S604: determining the current remaining power of the battery based on the discharge parameters of the third power range.

[0143] When simulating the remaining power, when the discharge parameter at the end of discharge is fixed, no matter how the discharge parameter changes during the discharge process, the discharge parameter at the end of discharge is fixed, and therefore, the current remaining power of the battery is simulated directly based on the discharge parameter of the third power range. The third power range is the smallest power range among the N second power ranges, for example, the third power range is 0%.

[0144] Step S605, the product of the remaining power and the power proportion corresponding to each second power range is determined as the available power corresponding to each second power range, and the sum of the ratios of the available power corresponding to multiple second power ranges and the corresponding discharge parameters is determined as the available time of the battery.

[0145] The remaining power determined in step S604 is the total remaining power of the battery. For each second power range, the available power corresponding to each second power range is a part of the remaining power, that is, the product of the remaining power and the power percentage corresponding to each second power range is determined as the available power corresponding to each second power range. The power percentage corresponding to the second power range is used to characterize the proportion of the available power corresponding to the second power range in the remaining power. Then, for each second power range, the ratio of the available power corresponding to the second power range to the corresponding discharge parameter is determined as the available time corresponding to the second power range, and the sum of the available time corresponding to multiple second power ranges is determined as the available time of the battery.

[0146] In some embodiments, for each second power range, based on historical usage data, a historical power difference and a historical remaining power corresponding to the second power range are determined, wherein the historical power difference is the difference between a first historical power corresponding to the upper limit value of the second power range and a second historical power corresponding to the lower limit value of the second power range, and the historical remaining power is the remaining power of the battery when the historical visible power is the current visible power; the ratio of the historical power difference to the historical remaining power is determined as the power ratio corresponding to the second power range.

[0147] Optionally, obtain historical usage data of the battery L times, obtain the historical remaining power when the visible power in each historical usage data is the current visible power of the battery, and the historical power difference corresponding to each second power range; for each second power range, obtain the ratio of each historical power difference corresponding to the second power range to the historical remaining power, obtain L ratios, and determine the average of the L ratios as the power ratio corresponding to the second power range.

[0148] For example, taking the current visible power as 20%, the second power range includes 20%-5%, 5%-3%, 3%-1% and 0% as an example, the average values ​​of K historical discharge parameters, upper limit discharge parameters and power proportions corresponding to different second power ranges are shown in Table 1:

[0149] Table 1

[0150]

[0151]

[0152] According to the parameters shown in Table 1, in the first operating mode, the calculation formula for the available time is:

[0153] t=μ1*R M / P1+μ2*R M / P2+μ3*R M / P3+μ4*R M / P4

[0154] Among them, t is the available time, R M is the remaining power, and the other parameters are the parameters shown in Table 1.

[0155] In the second operating mode, the calculation formula for the available time is:

[0156] t=μ1*R M / P N1 +μ2*R M / P N2 +μ3*R M / P N3 +μ4*R M / P N4

[0157] Among them, t is the available time, R M is the remaining power, P N1 For P1 and P M1 The minimum value in P N2 For P2 and P M2 The minimum value in P N3 For P3 and P M3 The minimum value in P N4 For P4 and P M4 The minimum value in .

[0158] Step S606, displaying the available time.

[0159] In the method provided by the embodiment of the present disclosure, the discharge parameter is determined based on the user's historical usage or the upper limit discharge parameter in the second operating mode, taking into account the user's usage habits and the operating mode of the battery, and adopting corresponding discharge parameters in different operating modes. In addition, in order to more accurately represent the usage of the battery under the remaining power, it is also considered that the user's usage of the electronic device may be different under different power levels, and the corresponding discharge parameters are determined for each second power range respectively, so that the available time of the battery determined based on the discharge parameters and the remaining power of each second power range is more accurate, thereby improving the accuracy of the available time and enhancing the user experience.

[0160] In one example, Figure 6 The embodiment shown can be Figure 7 As shown, the preset threshold is 20%, and four second power ranges are divided into 20%-5%, 5%-3%, 3%-1% and 0%, see Figure 7 , including the following steps:

[0162] 2. Determine whether the power saving mode is turned on. If the power saving mode is not turned on, go to step 3. If the power saving mode is turned on, go to step 6.

[0163] 3. Based on the historical usage data, the discharge parameters of the four second power ranges are determined respectively.

[0164] The implementation of step 3 refers to the above step S602 and will not be repeated here.

[0165] 4. Calculate the remaining power based on the discharge parameters of the second minimum power range.

[0166] 5. Calculate the usable time of the battery based on the discharge parameters, power percentage and remaining power of the four second power ranges.

[0167] The implementation of steps 4 and 5 refers to the above steps S604 and S605, which will not be described in detail here.

[0168] 6. Obtain upper limit discharge parameters corresponding to four second power ranges, and determine discharge parameters of the four second power ranges respectively based on historical usage data.

[0169] 7. Compare the upper limit discharge parameter corresponding to each second power range with the discharge parameter determined based on historical data to determine the discharge parameter of each second power range.

[0170] The implementation of steps 6 and 7 refers to the above step S603 and will not be repeated here.

[0171] 8. Calculate the remaining power based on the discharge parameters of the second minimum power range.

[0172] 9. Calculate the usable time of the battery based on the discharge parameters, power percentage and remaining power of the four second power ranges.

[0173] The implementation of steps 8 and 9 refers to the above steps S604 and S605, which will not be described in detail here.

[0174] 10. Display the available time.

[0175] In addition, it should be noted that the above implementation is only described by taking the prediction of the available battery life under the current visible power as an example. In another embodiment, the same implementation can also be used to predict the available battery life under other visible power levels. Optionally, the above implementation is used to predict the available battery life once every preset time, so that the user can obtain the latest available time. The preset time is any preset time, for example, the preset time is 5 minutes, 10 minutes or other time.
