[0038] The power detection method provided in this application embodiment can be executed by the processor of an electronic device when running a computer program with corresponding functions. By acquiring the detected power of the battery at time k+1, and determining the actual power of the battery at time k+1 based on the relationship between the detected power of the battery at time k+1 and the actual power at time k, the method can effectively improve the accuracy of the power detection results compared to the method of calculating the power of the battery based on the collected battery voltage.

[0039] In application, the power detection method can be applied to any electronic device equipped with a battery and capable of detecting the battery's power level, such as wireless headphones, charging cases, power banks, mobile phones, tablets, laptops, netbooks, personal digital assistants (PDAs), augmented reality (AR) devices, virtual reality (VR) devices, electronic clocks, and smart wearable devices.

The battery can be a rechargeable battery with both charging and discharging functions, or a non-rechargeable battery with only discharging functions.

[0040] like Figure 1 As shown, the power detection method provided in this application embodiment includes the following steps S101 and S102:

[0041] Step S101: Obtain the detected battery charge at time k+1, and proceed to step S102.

[0042] In this application, k is any positive integer, and the (k+1)th time can be any time within which the battery level of the electronic device needs to be detected. The electronic device can periodically acquire the battery's detected battery level, with the (k+1)th time being any time within the (k+1)th acquisition cycle. The battery voltage is acquired by the electronic device's voltage acquisition module, which can be set independently or integrated into the processor. The voltage acquisition module can be implemented using an analog-to-digital converter (ADC). The voltage acquisition module acquires the battery voltage in the (k+1)th detection cycle and sends it to the processor. Based on the battery voltage, the processor calculates the detected battery level at the (k+1)th time.

[0043] In applications, the battery's detected charge at time k+1 can be calculated based on only one voltage collected in the (k+1)th acquisition cycle to improve detection efficiency. However, collecting only one voltage may lead to inaccurate charge readings due to sudden voltage changes. Therefore, the battery's detected charge at time k+1 can also be calculated by averaging the multiple voltages collected in the (k+1)th acquisition cycle to improve accuracy. Alternatively, m voltages can be collected in the (k+1)th acquisition cycle, abnormal voltages can be removed, and the battery's detected charge at time k+1 can be calculated based on the average of the remaining voltages. Here, m is an integer greater than 2, and the number of abnormal voltages can be zero. Abnormal voltages are determined by obtaining the median of the m voltages, calculating the voltage difference between each of the m voltages and the median, and identifying any voltage difference outside a preset range as an abnormal voltage. The preset voltage difference range can be set according to actual needs.

[0044] like Figure 2 As shown, in one embodiment, step S101 includes the following steps S201 to S203:

[0045] S201. Collect the battery voltage multiple times at time k+1 to obtain multiple voltages of the battery at time k+1, and proceed to step S202.

[0046] S202. Obtain the average value of multiple voltages of the battery at time k+1, and proceed to step S203;

[0047] S203. Based on the average value, obtain the detected charge of the battery at time k+1.

[0048] In applications, the (k+1)th time can be the (k+1)th moment, a moment before the (k+1)th moment, or a time period including the (k+1)th moment. To improve the accuracy of the acquired detected battery power, multiple battery voltages collected at the (k+1)th moment, a moment before the (k+1)th moment, or a time period including the (k+1)th moment can be used to calculate the battery's detected battery power at the (k+1)th moment. When the (k+1)th time is a time period including the (k+1)th moment, the (k+1)th moment can be any moment within the (k+1)th time period, such as the start time, middle time, or end time. When the electronic device periodically acquires the battery's detected battery power, the (k+1)th time can be any moment within the (k+1)th acquisition cycle.

[0049] Step S102: Determine the actual charge of the battery at time k+1 based on the relationship between the detected charge at time k+1 and the actual charge at time k.

[0050] In this application, time k is the previous time before time k+1. When an electronic device periodically acquires the battery's detected power level, the k-th acquisition period is the previous period before the (k+1)-th acquisition period, time k is any time within the k-th acquisition period, and time k is any time within the k-th acquisition period. It should be understood that the logical relationship between time k, the k-th acquisition period, and time k is the same as the logical relationship between time k+1, the (k+1)-th acquisition period, and time k+1, and will not be elaborated further here.

[0051] In applications, when the power module of an electronic device is connected to an external power source to charge the battery, the charging pin of the power module is connected to a voltage from the external power source, which enables the processor to detect the voltage signal. The processor determines that the battery is in a charging state based on the voltage signal. If the processor does not detect the voltage signal, it determines that the battery is in a discharging state. If the battery is neither charging nor discharging, the electronic device is turned off.

[0052] In applications, when the battery is charging, its charge level will continuously increase. Therefore, theoretically, when the battery is charging, the detected charge level at time k+1 should be greater than the actual charge level at time k. If the detected charge level at time k+1 is less than or equal to the actual charge level at time k, it indicates that the detected charge level at time k+1 is inaccurate. Similarly, when the battery is discharging, its charge level will continuously decrease. Therefore, theoretically, when the battery is discharging, the detected charge level at time k+1 should be less than the actual charge level at time k. If the detected charge level at time k+1 is greater than or equal to the actual charge level at time k, it indicates that the detected charge level at time k+1 is inaccurate. In applications, the detected battery charge at time k+1 may be inaccurate. Therefore, it is necessary to refer to the actual battery charge at time k. Based on the relationship between the detected battery charge at time k+1 and the actual battery charge at time k, it is necessary to determine whether the detected battery charge at time k+1 is accurate. If it is inaccurate, the detected battery charge at time k+1 needs to be corrected, and the corrected detected battery charge at time k+1 is taken as the actual battery charge at time k+1. In this way, the accuracy of the charge detection results can be effectively improved.

[0053] like Figure 3 As shown, in one embodiment, step S102 includes:

[0054] Step S300: Determine the actual charge of the battery at time k+1 based on the battery's charge / discharge state at time k+1, the detected charge, and the actual charge at time k.

[0055] In applications, the relationship between the detected charge level and the actual charge level at time k+1 varies depending on the battery's charge / discharge state. Therefore, it is necessary to combine the battery's charge / discharge state, the detected charge level, and the actual charge level at time k+1 to determine the battery's actual charge level at time k+1.

[0056] like Figure 4 As shown, in one embodiment, step S300 includes steps S401 to S403:

[0057] Step S401: If the battery is in a charging state and the detected charge of the battery at time k+1 is less than or equal to the actual charge at time k, determine that the actual charge of the battery at time k+1 is equal to the actual charge at time k.

[0058] Step S402: When the battery is in a charging state and the detected charge of the battery at time k+1 is greater than the actual charge at time k, obtain the first charge difference between the detected charge of the battery at time k+1 and the actual charge at time k, and proceed to step S403.

[0059] Step S403: Determine the actual charge of the battery at time k+1 based on the first charge difference.

[0060] In the application, when the battery is charging, if the detected battery charge at time k+1 is less than or equal to the actual battery charge at time k, the actual battery charge at time k can be used as the actual battery charge at time k+1. If the detected battery charge at time k+1 is greater than the actual battery charge at time k, a first charge difference between the detected battery charge at time k+1 and the actual battery charge at time k can be obtained, and the actual battery charge at time k+1 can be determined based on the magnitude of the first charge difference.

[0061] like Figure 5 As shown, in one embodiment, step S403 includes steps S501 and S502:

[0062] Step S501: If the first power difference is within the range of the first preset power difference, determine that the actual power of the battery at time k+1 is equal to the detected power at time k+1, and proceed to step S502.

[0063] In application, theoretically, when the battery is charging, the charging rate (positive value) is known. The first charge difference should be less than or equal to the product of the charging rate and the time difference between time (k+1) and time (k). The lower limit of the first preset charge difference range is greater than 0, and the upper limit of the first preset charge difference range should be less than or equal to the product of the charging rate and the time difference between time (k+1) and time (k). Therefore, the first preset charge difference range can be (0, the product of the charging rate and the time difference between time (k+1) and time (k)). The battery charging rate is determined based on the known battery charging curve, which reflects the relationship between the battery voltage and charging time.

[0064] Step S502: If the first power difference is not within the range of the first preset power difference, determine that the actual power of the battery at time k+1 is equal to the sum of the actual power at time k and the first preset power value corresponding to the first power difference.

[0065] In application, if the first charge difference is not within the range of the first preset charge difference when the battery is charging, it indicates that the detected charge at time k+1 is inaccurate. In this case, the sum of the actual charge at time k and the first preset charge value corresponding to the first charge difference can be taken as the actual charge at time k+1. The first preset charge value can be determined according to the battery's charging rate.

[0066] like Figure 6 As shown, in one embodiment, step S502 includes:

[0067] Step S600: If the first power difference is not within the range of the first preset power difference, determine that the actual power of the battery at time k+1 is equal to the sum of the actual power at time k and the first preset power value corresponding to the first power difference interval where the first power difference is located.

[0068] In application, the first power difference interval is one of m first preset power difference intervals, where m is an integer greater than or equal to 2. When the battery is charging, all m first preset power difference intervals are positive power intervals, and the corresponding m first preset power values ​​are all positive power values. The m first preset power difference intervals can be obtained by subdividing the positive interval (the upper limit of the first preset power difference range, +∞) into m continuous or discontinuous intervals. The relationship between the m first preset power values ​​can be linear or stepwise, where the largest third preset power value is equal to the product of the charging rate and the time difference between time k+1 and time k. When the battery is charging, by setting multiple subdivided first power difference intervals when the first power difference is not within the first preset power difference range, and then finely adjusting the detected power of the battery at time k+1 according to the first power difference interval in which the first power difference is located, the actual power of the battery at time k+1 can be determined, thus effectively improving the accuracy of the power detection results.

[0069] like Figure 7 As shown, an exemplary illustration illustrates the relationship between the detected charge level and the actual charge level of the battery at time k+1 when the battery is in a charging state.

[0070] like Figure 8 As shown, in one embodiment, step S300 includes steps S701 to S703:

[0071] Step S701: If the battery is in a discharging state and the detected charge of the battery at time k+1 is greater than or equal to the actual charge at time k, determine that the actual charge of the battery at time k+1 is equal to the actual charge at time k.

[0072] Step S702: When the battery is in a discharging state and the detected charge of the battery at time k+1 is less than the actual charge at time k, obtain the second charge difference between the detected charge of the battery at time k+1 and the actual charge at time k, and proceed to step S703.

[0073] Step S703: Determine the actual charge of the battery at time k+1 based on the second charge difference.

[0074] In application, when the battery is in a discharging state, if the detected charge of the battery at time k+1 is greater than or equal to the actual charge at time k, the actual charge of the battery at time k can be taken as the actual charge of the battery at time k+1. If the detected charge of the battery at time k+1 is less than the actual charge at time k, a second charge difference between the detected charge at time k+1 and the actual charge at time k can be obtained. The actual charge of the battery at time k+1 is determined based on the magnitude of the second charge difference.

[0075] like Figure 9 As shown, in one embodiment, step S703 includes steps S801 and S802:

[0076] Step S801: If the second power difference is within the range of the second preset power difference, determine that the actual power of the battery at time k+1 is equal to the detected power at time k+1, and proceed to step S802.

[0077] In application, theoretically, when the battery is in a discharging state, the discharge rate (negative value) is known. The second charge difference should be greater than or equal to the product of the discharge rate and the time difference between time (k+1) and time (k). The lower limit of the second preset charge difference range should be greater than or equal to the product of the discharge rate and the time difference between time (k+1) and time (k), and the upper limit of the second preset charge difference range should be less than 0. Therefore, the second preset charge difference range can be [the product of the discharge rate and the time difference between time (k+1) and time (k), 0]. The battery's discharge rate is determined based on the known battery discharge curve, which reflects the relationship between the battery's voltage and discharge time.

[0078] Step S802: If the second power difference is not within the range of the second preset power difference, determine that the actual power of the battery at time k+1 is equal to the sum of the actual power at time k and the second preset power value corresponding to the second power difference.

[0079] In application, if the second charge difference is not within the range of the second preset charge difference when the battery is discharging, it indicates that the detected charge at time k+1 is inaccurate. In this case, the sum of the actual charge at time k and the second preset charge value corresponding to the second charge difference can be taken as the actual charge at time k+1. The second preset charge value can be determined according to the battery's discharge rate.

[0080] like Figure 10 As shown, in one embodiment, step S802 includes:

[0081] Step S900: If the second power difference is not within the range of the second preset power difference, determine that the actual power of the battery at time k+1 is equal to the sum of the actual power at time k and the second preset power value corresponding to the second power difference interval where the second power difference is located.

[0082] In application, the second power difference interval is one of n second preset power difference intervals, where n is an integer greater than or equal to 2. When the battery is discharging, all n second preset power difference intervals are negative power intervals, and the corresponding n second preset power values ​​are all negative power values. The n second preset power difference intervals can be obtained by subdividing the negative interval (-∞, the lower limit of the second preset power difference range) into n continuous or discontinuous intervals. The relationship between the n second preset power values ​​can be linear or stepwise decreasing, where the smallest second preset power value is equal to the product of the discharge rate and the time difference between time k+1 and time k. By setting multiple subdivided second power difference intervals when the second power difference is not within the second preset power difference range, and then finely adjusting the detected power of the battery at time k+1 according to the second power difference interval in which the second power difference is located, the actual power of the battery at time k+1 can be determined, thus effectively improving the accuracy of the power detection results.

[0083] like Figure 11 As shown, an exemplary illustration is provided of the relationship between the detected charge and the actual charge of the battery at time k+1 when the battery is in a discharging state.

[0084] like Figure 12 As shown, in one embodiment, step S102 includes steps S111 and S112:

[0085] Step S111: Obtain the third power difference between the detected power level of the battery at time k+1 and the actual power level at time k; Step S112:

[0086] Step S112: Determine the actual charge of the battery at time k+1 based on the third charge difference.

[0087] In practice, theoretically, when the battery is charging, the third charge difference between the detected charge at time k+1 and the actual charge at time k should be greater than 0. If the third charge difference is less than or equal to 0, it indicates that the detected charge at time k+1 is inaccurate. When the battery is discharging, the third charge difference should be less than 0. If the third charge difference is greater than or equal to 0, it indicates that the detected charge at time k+1 is inaccurate.

[0088] In applications, since the detected battery charge at time k+1 may be inaccurate, it is necessary to refer to the actual battery charge at time k. The actual battery charge at time k+1 is then determined based on the third charge difference between the theoretical charge at time k+1 and the actual charge at time k. This can effectively improve the accuracy of the charge detection results.

[0089] like Figure 13 As shown, in one embodiment, step S112 includes steps S121 to S123:

[0090] Step S121: If the third power difference is within the range of the third preset power difference, determine that the actual power of the battery at time k+1 is equal to the actual power at time k.

[0091] Step S122: If the third power difference is within the range of the fourth preset power difference, determine that the actual power of the battery at time k+1 is equal to the detected power at time k+1.

[0092] Step S123: If the third power difference is not within the range of the third preset power difference and not within the range of the fourth preset power difference, determine that the actual power of the battery at time k+1 is equal to the sum of the actual power at time k and the third preset power value corresponding to the third power difference.

[0093] In application, if the third power difference is within the range of the third preset power difference, the actual power of the battery at time k can be taken as the actual power of the battery at time k+1. If the third power difference is within the range of the third preset power difference, it can be further determined whether the third power difference is within the range of the fourth preset power difference. If it is, the detected power of the battery at time k+1 is taken as the actual power of the battery at time k+1. If it is not, it indicates that the detected power of the battery at time k+1 is inaccurate. In this case, the sum of the actual power of the battery at time k and the third preset power value corresponding to the third power difference can be taken as the actual power of the battery at time k+1.

[0094] In application, when the battery is charging, the upper limit of the third preset power difference range is less than or equal to 0, and the third preset power difference range can be set to (-∞, 0). The lower limit of the fourth preset power difference range is greater than 0, and the upper limit of the fourth preset power difference range should be less than or equal to the product of the charging rate and the time difference between time k+1 and time k. Therefore, the fourth preset power difference range can be (0, the product of the charging rate and the time difference between time k+1 and time k). The third preset power value can be determined according to the battery's charging rate; for example, the third preset power value is equal to the product of the charging rate and the time difference between time k+1 and time k.

[0095] In application, when the battery is discharging, the lower limit of the third preset charge difference range is greater than or equal to 0, and the third preset charge difference range can be set to [0, +∞). The upper limit of the fourth preset charge difference range is less than 0, and the upper limit of the fourth preset charge difference range should be less than or equal to the product of the discharge rate and the time difference between time k+1 and time k. Therefore, the fourth preset charge difference range can be [the product of the discharge rate and the time difference between time k+1 and time k, 0). The third preset charge value can be determined according to the battery's discharge rate; for example, the third preset charge value is equal to the product of the discharge rate and the time difference between time k+1 and time k.

[0096] like Figure 14 As shown, in one embodiment, step S123 includes:

[0097] Step S130: If the third power difference is not within the range of the third preset power difference and not within the range of the fourth preset power difference, determine that the actual power of the battery at time k+1 is equal to the sum of the actual power at time k and the third preset power value corresponding to the power difference interval where the third power difference is located.

[0098] In application, the third power difference interval is one of q third preset power difference intervals, where q is an integer greater than or equal to 2. When the battery is charging, q = q1, and all q1 third preset power difference intervals are positive power intervals, corresponding to q1 third preset power values ​​that are all positive power values. The q1 third preset power difference intervals can be obtained by subdividing the positive interval (the upper limit of the fourth preset power difference range, +∞) into q1 continuous or discontinuous intervals. The relationship between the q1 third preset power values ​​can be linear or stepwise increasing, where the largest third preset power value is equal to the product of the charging rate and the time difference between time k+1 and time k. When the battery is discharging, q = q², and all q² third preset charge difference intervals are negative charge intervals, corresponding to q² third preset charge values ​​that are all negative. These q² third preset charge difference intervals can be obtained by subdividing the negative interval (-∞, the lower limit of the fourth preset charge difference range) into q² continuous or discontinuous intervals. The relationship between these q² third preset charge values ​​can be linear or stepwise decreasing, where the smallest third preset charge value equals the product of the discharge rate and the time difference between time k+1 and time k. By setting multiple subdivided third charge difference intervals when the third charge difference is not within the fourth preset charge difference range, and then finely adjusting the detected charge at time k+1 based on the third charge difference interval in which the third charge difference falls, the actual charge at time k+1 can be determined, thus effectively improving the accuracy of the charge detection results.

[0099] like Figure 15 As shown, an exemplary illustration illustrates the relationship between the battery's charge / discharge state at time k+1, the third charge difference, and the actual charge.

[0100] In one embodiment, after step S103, the following is included:

[0101] This displays the actual charge level of the battery at time k+1.

[0102] In applications, the actual battery level is displayed via a display device on the electronic device. This display device can be, but is not limited to, a display screen, a seven-segment or eight-segment LED display, or at least one of these. After determining the actual battery level at time k+1, the electronic device can display this actual battery level so that the user can know the real-time battery status. The electronic device can also perform power management on the battery based on the actual battery level at each time point.

[0103] In applications, when the battery is discharging, if the battery level falls below a first power threshold, a corresponding initial warning message will be issued to remind the user that the electronic device is low on power and needs charging. It can also automatically enter sleep mode, low-power mode, or reduce the brightness of the display. For example, when the electronic device is a mobile terminal with a power load, such as a mobile phone, tablet, laptop, netbook, personal digital assistant (PDA), augmented reality (AR) device, virtual reality (VR) device, or smart wearable device, background applications can be closed to save power. The first power threshold can be set to a low threshold, such as 20% of the battery's nominal capacity.

[0104] In the application, when the battery is charging, if the battery level exceeds a second power threshold, a corresponding second prompt message will be issued to remind the user that the electronic device has sufficient power. It may also automatically exit sleep mode or low-power mode, or increase the brightness of the display device. The second power threshold can be set to a relatively high threshold, for example, 80% of the battery's nominal capacity.
