DETAILED DESCRIPTION OF ASPECTS OF THE INVENTION

[0011] An information processing method and an electronic device according to the embodiment of the present application, which are used to solve the technical problem that the calibration of the battery capacity in the prior art can only be carried out in a fully charged state of the battery present in the electronic device, thus achieves the technical effect that the calibration of the battery capacity in the battery can be realized in a not fully charged state.

[0012] To solve the aforementioned technical problem, the technical solution in the embodiment of the present application proposes the following general idea: Receive at least one initial battery status message when the electronic device's battery is in its initial sleep state; Receiving at least one second battery status message of the battery in a second hibernation state and the charging or discharging capacity of the battery during the first hibernation state and the second hibernation state, if it has been determined that the battery transitions from the first hibernation state to non-hibernation state and from non-hibernation state to the second hibernation state, wherein, when the battery is in the first hibernation state and the second hibernation state, both the charging current and the discharging current of the battery are zero.

[0013] The actual full charging capacity of the battery can be calculated based on at least one first battery status message, at least one second battery status message, and the charging or discharging capacity.

[0014] In the aforementioned technical solution, wherein at least one initial battery status message is received when the battery of the electronic device is in an initial sleep state; at least one second battery status message is received in a second sleep state; and the charging or discharging capacity of the battery is determined during the initial sleep state and the second sleep state when it is determined that the battery transitions from the initial sleep state to the non-sleep state and from the non-sleep state to the second sleep state, wherein, when the battery is in the initial sleep state and the second sleep state, the charging and discharging currents of the battery are each zero; the actual full charge capacity of the battery can be determined based on the at least one initial battery status message.The battery's full charge capacity can be calculated from at least one second battery status message and the charging or discharging capacity. Unlike the prior art, where the battery must first be fully charged and then discharged from 100% to 1% to calibrate its capacity, recording the actual discharged capacity to correct the reported capacity, this technical solution allows the actual full charge capacity of the battery to be calculated based on the status messages received between the two resting states of the electronic device's battery, as well as the charging or discharging capacity between these states, without requiring the battery to be fully charged beforehand. This solves the prior art technical problem.that the calibration of the battery capacity can only be carried out when the battery in the electronic device is fully charged, thereby achieving the technical effect that the calibration of the battery capacity can even be realized in the battery when it is not fully charged.

[0015] For a better understanding of the above-mentioned technical solution, the technical solution of the present invention is subsequently described in detail with reference to the drawings and specific embodiments, whereby it is to be understood that the embodiments of the present application and the specific characteristics in the embodiments are intended to serve the detailed description of the technical solution of the present invention and are not to be regarded as restrictive, wherein the embodiments of the present application and the technical characteristics in the embodiments can be combined with each other in the event that there are no conflicts. First embodiment

[0016] An information processing method according to the first embodiment of the present application can be used for an electronic device, wherein the electronic device may be a smartphone, a tablet PC or a notebook as well as another electronic device; wherein no special limits are set in this regard in this embodiment of the present application.

[0017] See Fig. 1. The present application provides an information processing system comprising the following: S101: Receive / determine at least one initial battery status message when the electronic device's battery is in its initial sleep state; S102: Obtain at least one second battery state message of the battery in a second hibernation state and the charge or discharge capacity of the battery during the first hibernation state and the second hibernation state when it is determined that the battery transitions from the first hibernation state to non-hibernation and from non-hibernation to the second hibernation state, wherein the charge and discharge current of the battery are each zero when the battery is in the first hibernation state and the second hibernation state; and wherein, from the at least one first battery state message, the at least one second battery state message, and the charge or discharge capacity, the actual full charge capacity of the battery can be calculated.

[0018] In the embodiment of the present application, step S101 is performed first: Obtaining / determining at least one initial battery status message when the battery of the electronic device is in the initial sleep state.

[0019] The specific implementation of step S101 in the embodiment of the present application comprises: Obtaining the initial current remaining battery capacity when the electronic device's battery is in its initial sleep state, and obtaining the initial cell temperature of the battery cell.

[0020] The concrete implementation of step S102 therefore includes: Maintaining the second current remaining battery capacity of the electronic device's battery in the second resting state and maintaining the second cell temperature of the cell.

[0021] In the specific implementation, the historical power consumption data of the battery must also be preserved, since in the embodiment of the present application, the historical power consumption data is stored in the BMU (Battery Management Unit) of the electronic device, wherein the BMU is arranged on the circuit board inside the battery and is always and directly powered by the battery cell, and wherein the BMU is also always in an operating state, even when the electronic device is in switched-off mode, therefore the step of preserving the historical power consumption data of the battery can be determined both before step S101, after the execution of step S101, or during the execution of step S101.All three of the above implementation methods are applicable and can be selected by the person skilled in the art in this field according to the actual needs; no special restrictions are imposed in the embodiment of the present application.

[0022] In the embodiment of the present application, the historical full charge capacity of the battery is taken, in particular as a concrete example of the historical power consumption data, such as 38 Wh or 40 Wh, wherein in the embodiment of the present application the historical full charge capacity of the battery is, in particular, a full charge capacity updated via a recent calculation or a primary full charge capacity at the time of the first use of the battery, such asa full charge and discharge test, which is carried out for the battery of the electronic device in the factory before leaving the factory, calculating the primary full charge capacity of the battery, wherein both of the above situations are executable, wherein the historical full charge capacity is determined as appropriate to the situation as a full charge capacity updated via a last calculation or a primary full charge capacity, whereby in the embodiment of the present application no special restrictions are imposed in this respect.

[0023] In addition to the step of obtaining the historical full charge capacity of the battery, the concrete implementation also requires determining the first current remaining battery capacity in the initial resting state and the first cell temperature of the battery cell, in particular, for example: the determined first current remaining battery capacity is 30 Wh and represents 80% of the historical full charge capacity, with the first cell temperature being 20 degrees.

[0024] Accordingly, in the embodiment of the present application, at least one second battery status message of the electronic device must also be obtained in a second sleep state, wherein in the specific implementation the method before obtaining the at least one second battery status message of the electronic device in the second sleep state further comprises the following: Obtain / determine the current remaining battery capacity.

[0025] Perform the following step if the difference between the current remaining battery capacity and the first remaining battery capacity is within a preset range: Obtain the second current remaining battery capacity of the battery in the second resting state and the second cell temperature of the cell.

[0026] To ensure the calibration accuracy of the battery capacity in the specific implementation, it should be ensured that the change in the percentage of the remaining battery capacity between the two resting states lies within the preset range, wherein the preset range in the embodiment of the present application is, in particular, 30%-50%; the reason for limiting the preset range to 30%-50% in the embodiment of the present application is that if the change in the percentage of the remaining battery capacity is less than 30%, as is the case, for example,2%, the battery capacity must be calibrated after a moment of use of the electronic device, thus increasing the frequency of calibration and causing inconvenience to the user; if the change in the percentage of remaining battery capacity is higher than 50%, such as 80%, the battery capacity will only be calibrated when there is a larger change in the percentage of remaining battery capacity, thus reducing the number of automatic battery capacity calibrations and affecting the accuracy of the battery capacity calibration.

[0027] In the specific implementation, the preset range is 11 Wh-30 Wh, where the received current remaining battery capacity is 11 Wh and represents 30% of the historical full charge capacity, and where the first current remaining battery capacity is 30 Wh, namely, the difference of 19 Wh between the current remaining battery capacity and the first current remaining battery capacity lies within the preset range of 11 Wh-30 Wh, and at least one second battery status message is received from the battery in the second sleep state.

[0028] In the embodiment of the present application, the at least one specific second battery status message is the second current remaining battery capacity, the second cell temperature of the cell and the charging or discharging capacity between the first rest state and the second rest state, such as, for example, the second current remaining battery capacity is 11 Wh, the second cell temperature is 25 degrees and the discharge capacity is 20 Wh.

[0029] In the embodiment of the present application, the charging current and the discharging current of the battery are each zero when the battery is in the first resting state and the second resting state.

[0030] See Fig. 2, in the embodiment of the present application, the procedure after performing step S102 further comprises the following: S201: Obtaining the current calculated full charge capacity of the battery based on the first current remaining battery capacity, the second current remaining battery capacity and the charging or discharging capacity, where the current calculated full charge capacity is a current full charge capacity of the battery determined by calculation; S202: Maintaining the actual full charge capacity of the battery based on historical power consumption data, the current calculated full charge capacity, the first cell temperature, and the second cell temperature.

[0031] In the concrete implementation, step S201 is executed first: Obtaining the current calculated full charge capacity of the battery based on the first current remaining battery capacity, the second current remaining battery capacity and the charging or discharging capacity, where the current calculated full charge capacity is a full charge capacity of the battery currently determined by calculation.

[0032] In the embodiment of the present application, after obtaining the first current remaining battery capacity, the second current remaining battery capacity, and the charging or discharging capacity between the first hibernation state and the second hibernation state, the current calculated full charge capacity of the battery is calculated using the formula FCC1=PC / (RSOC1-RSOC2), where FCC1 is the current calculated full charge capacity of the battery and PC is the charging or discharging capacity, and where RSOC1 and RSOC2 are the percentage of the first remaining battery capacity and the percentage of the second remaining battery capacity, respectively, calculated from the first current remaining battery capacity and the second current remaining battery capacity.

[0033] Given the conditions PC=20 wh, RSOC1=80 % and RSOC2=30 %, the current calculated full charge capacity of the battery, which is 40 wh, can be calculated in the concrete implementation by inserting these values ​​into the above-mentioned formula.

[0034] After performing step S201, in the embodiment of the present application, step S202 must be performed: Obtaining the actual full charge capacity of the battery based on the historical power consumption data, the current calculated full charge capacity, the first cell temperature and the second cell temperature.

[0035] See Fig. 3, the concrete implementation of step S201 in the concrete implementation includes in particular the following steps: S301: Obtaining a rate of change of the full charge capacity based on the historical full charge capacity, the current calculated full charge capacity, the first cell temperature and the second cell temperature, where the rate of change is a ratio of the difference between the historical full charge capacity and the current calculated full charge capacity to the difference between the first cell temperature and the second cell temperature; S302: Use the historical full charging capacity as the actual full charging capacity if the rate of change is higher than a preset value; S303: Use the current calculated full charging capacity as the actual full charging capacity if the rate of change is lower than the preset value.

[0036] In the embodiment of the present application, the historical full charge capacity of the battery is taken as an example of the historical power consumption data.

[0037] Due to cumulative errors during the calculation, in the concrete implementation, after calculating the current calculated full charge capacity of the battery, it is possible that the calculated current full charge capacity is not the actual full charge capacity of the battery. Therefore, the rate of change of the full charge capacity must also be calculated based on the obtained current calculated full charge capacity, the historical full charge capacity, the first cell temperature and the second cell temperature, and with the corresponding formula (FCC1-FCC0) / (T2-T1), where FCC0 is the historical full charge capacity, T1 is the first cell temperature and T2 is the second cell temperature.

[0038] After calculating the rate of change, the rate of change and a preset value are compared, with the historical full load capacity being used as the actual full load capacity if the rate of change is higher than a preset value, and with the current calculated full load capacity being used as the actual full load capacity if the rate of change is lower than a preset value.

[0039] If, during the actual implementation, under the conditions of FCC1=40wh, FCC0=38wh, T1=25 degrees and T2=20 degrees, the calculated rate of change is 0.4 and the preset value is 1, the rate of change is lower than the preset value and the currently calculated full charging capacity is used as the actual full charging capacity, namely 40 wh.

[0040] In the embodiment of the present application, the method, after the step of obtaining the actual full charging capacity based on the at least one first battery status message, the at least one second battery status message and the charging or discharging capacity, further comprises the following: Obtaining an initial discharge capacity of the battery, where the initial discharge capacity is a capacity discharged by the battery from a fully charged state to the current time; Obtaining the current actual remaining battery capacity and the percentage of the current actual remaining battery capacity of the battery at the current time based on the actual full charge capacity and the first discharge capacity.

[0041] In the concrete implementation, after obtaining the actual full charge capacity, the first discharge capacity of the battery must also be obtained in order to adjust the percentage of the remaining battery capacity. In the embodiment of the present application, the first discharge capacity is the capacity discharged by the battery from the fully charged state to the current time, such as a capacity discharged by the battery from 100% to 65%. In particular, the first discharge capacity is DC=26.6 Wh. If a calculation is now performed using the historical full charge capacity of FCC0=38 Wh, the percentage of the remaining battery capacity is 30%.

[0042] Since in the embodiment of the present application a calibration for the full charge capacity is completed and the actual full charge capacity updated after calibration is 40 Wh, the percentage of the current actual remaining battery capacity of the battery is (40 Wh-26.6 Wh) / 40 Wh = 34%, therefore the percentage of the remaining battery capacity of the battery should be adjusted to 34%.

[0043] Since, in the embodiment of the present application, the full charging capacity of the battery is calibrated and subsequently the percentage of the remaining battery capacity is calibrated and adjusted, the user can be provided with a percentage of the remaining battery capacity with high accuracy, so that the user can operate the electronic device appropriately based on the percentage of the actual remaining battery capacity, in order to avoid the electronic device suddenly switching off during the usage process due to inaccuracies in the displayed percentage of the remaining battery capacity, thus preventing inconvenience to the user; therefore, the technical solution in the embodiment of the present application can improve the user experience in comparison.

[0051] The following one or more technical effects can be achieved through one or more technical solutions in the embodiment of the present application: Since, in the embodiment of the present application, the technical solution is to obtain at least one first battery status message of the battery of an electronic device in an initial sleep state, at least one second battery status message of the battery in a second sleep state, and the charging or discharging capacity of the battery in the initial sleep state and the second sleep state when it is determined that the battery transitions from the initial sleep state to a non-sleep state and from the non-sleep state to the second sleep state, wherein the charging current and the discharging current of the battery are each zero when the battery is in the initial sleep state and the second sleep state, it is possible to determine, based on the at least one first battery status message,The actual full charge capacity of the battery can be calculated using at least one second battery status message and the charging or discharging capacity. Unlike the prior art, where the battery must first be fully charged and then discharged from 100% to 1% to calibrate the battery capacity, while the actually discharged capacity is recorded to correct the reported capacity, this technical solution allows the actual full charge capacity of the battery to be calculated based on the status messages received between the two resting states of the battery in the electronic device, as well as the charging or discharging capacity between the two resting states, without the need to fully charge the battery beforehand. This solves the prior art technical problem.that the calibration of the battery capacity can only be carried out when the battery in the electronic device is fully charged, thereby achieving the technical effect that the calibration of the battery capacity can even be realized in the battery when it is not fully charged.
