All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The battery detection method provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

Before describing the embodiments of the present application, a brief description will be first given of a discharge curve of a battery.

The discharge curve refers to a corresponding curve of the operating voltage and the remaining power of the electronic device. In a specific implementation, the electronic device may obtain the operating voltage of the electronic device by monitoring the voltage of the battery. The electronic device may detect the remaining power of the battery, typically in percent, by an electricity meter. And generating a discharge curve according to the working voltage and the residual electric quantity. During use of the electronic device, the discharge curve of the battery is used to display the amount of electricity. In the implementation, in the use process of the electronic equipment, the current working voltage of the electronic equipment is obtained in real time, and the current residual electric quantity corresponding to the current working voltage is obtained according to the current working voltage and the discharge curve of the battery, and is the display electric quantity of the electronic equipment.

Based on the above description, it is possible to display the electric quantity according to the discharge curve of the battery during the use of the electronic device. The standard discharge curve is stored in advance when the electronic device leaves the factory, and the electric quantity is displayed according to the stored standard discharge curve in the using process of the electronic device. However, after the battery is used for a period of time, the battery is aged due to long-term loss, so that a battery discharge curve is shifted, at this time, the electric quantity is displayed according to a pre-stored standard discharge curve, and a phenomenon that the displayed electric quantity is inconsistent with the actual electric quantity, such as a jump of the displayed electric quantity, occurs, and user experience is affected.

In order to solve the above-mentioned problems, the embodiment of the present application provides a battery detection method.

Referring to the flowchart shown in fig. 1, the method includes the following steps S1100-S1400.

Step S1100, a first discharge curve of the battery is obtained in a first manner.

The first discharge curve is an actual discharge curve of the battery acquired during use of the electronic device. In this embodiment, by acquiring the first discharge curve of the battery, the battery may be self-checked to determine whether the stored discharge curve of the electronic device needs to be updated, and under the condition that whether the stored discharge curve needs to be updated, the reminding information is output to remind the user to start the battery test function.

In some embodiments of the present application, the step of obtaining a first discharge curve of the battery in a first manner may further comprise: and under the condition that the using state of the battery meets the first preset condition, acquiring a first discharging curve of the battery in a first mode. Wherein the use state of the battery meeting the first preset condition includes at least one of: the number of charge-discharge cycles of the battery is greater than or equal to a first threshold; the battery life cycle is greater than or equal to the second threshold.

In this embodiment, the number of charge and discharge cycles is greater than or equal to the first threshold, or the service cycle of the battery is greater than or equal to the second threshold, which indicates that the performance of the battery may be significantly degraded, that is, the discharge curve of the battery may drift, and the first discharge curve of the battery needs to be obtained, and further whether to start the battery test function may be determined according to the first discharge curve.

In specific implementation, the number of charge and discharge cycles and the service cycle of the battery are obtained, and when the number of charge and discharge cycles of the battery is greater than or equal to a first threshold value or the service cycle of the battery is greater than or equal to a second threshold value, prompt information for prompting a user to obtain a first discharge curve of the battery is output.

For example, the first threshold is set to 800 times, and when the number of charge/discharge cycles of the battery is greater than or equal to 800 times, a prompt message prompting the user to acquire the first discharge curve of the battery is output. Of course, in practice, different first thresholds may be set for different models of batteries. And, as the battery performance is continuously improved, the first threshold value also needs to be adjusted. The first threshold value may be set based on experimental simulation data, and is not particularly limited herein.

For example, the second threshold is set to 12 months, and when the service cycle of the battery is greater than or equal to 12 months, a prompt message prompting the user to acquire the first discharge curve of the battery is output. Of course, in practice, a different second threshold may be set for different models of batteries. And, as the battery performance is continuously improved, the second threshold value also needs to be adjusted. The second threshold value may be set based on experimental simulation data, and is not particularly limited herein.

The first discharge curve may be a discharge curve in a full power interval, i.e. a discharge curve in a 100% -0% power interval. The first discharge curve may also be a discharge curve of a partial charge interval, for example, a discharge curve of a 90% -80% charge interval. In this embodiment, whether to start the battery test function may be determined through the first discharge curve of the full power interval, or whether to start the battery test function may be determined through the first discharge curve of the partial power interval. These two cases are respectively described below.

In some embodiments, the step of obtaining a first discharge curve of the battery in a first manner may further comprise: and obtaining a first discharge curve of the battery in a mode that the battery is discharged in a partial electric quantity interval with a first preset discharge rate.

The first preset discharge rate may be, for example, 0.1C. The partial power interval may be a power interval in which drift is likely to occur. For example, a power interval of 100% to 80%. That is, the battery is controlled to discharge at a discharge rate of 0.1C to obtain a first discharge curve within a 100% to 80% electric quantity interval.

It should be noted that, the partial power interval may be set by those skilled in the art according to simulation test data, and is not limited herein.

According to the embodiment of the application, the first discharge curve of the battery is obtained in a mode that the battery discharges in a partial electric quantity interval with the first preset discharge rate, so that the corresponding first discharge curve can be obtained aiming at the electric quantity interval which is easy to drift, the obtained discharge curve is high in precision, and whether to start a battery test function can be accurately judged by combining with the follow-up steps.

In other embodiments, the step of obtaining a first discharge curve of the battery in a first manner may further comprise: and obtaining a first discharge curve of the battery in a mode that the battery is discharged in a full-power interval with a second preset discharge rate. The second preset discharge rate is larger than the first preset discharge rate.

The second preset discharge rate may be, for example, 0.5C. Full electric quantity interval, namely 100% -0% electric quantity interval. That is, the battery is controlled to discharge at a discharge rate of 0.5C, and a first discharge curve in a 100% to 0% electric quantity interval is obtained.

According to the embodiment of the application, the first discharge curve of the battery is obtained in a mode that the battery discharges in the full-electric-quantity interval with the second preset discharge rate, so that the discharge curve of the 100% -0% full-electric-quantity interval can be obtained, whether to start a battery test function or not can be determined according to the first discharge curve of the full-electric-quantity interval in combination with the subsequent steps, the full-electric-quantity interval can be covered, and the detection accuracy is higher. In addition, under the condition that the battery is discharged at a second preset discharge rate, a discharge curve of the battery in a full-power interval is obtained, the accuracy is ensured, meanwhile, the time for generating the discharge curve can be reduced, and the curve obtaining efficiency is improved.

Step S1200, outputting a reminder message for reminding a user to start the battery test function under the condition that the smoothness of the first discharge curve is abnormal.

The smoothness of the discharge curve may reflect the correspondence of the operating voltage to the remaining power. Under the condition that the smoothness of the discharge curve is normal, the working voltage and the residual electric quantity have better correspondence, namely the duration of each certain electric quantity consumed under the same power consumption is the same. Under the condition that the smoothness of the discharge curve is abnormal, for example, a peak or a trough appears in the discharge curve, which indicates that the poorer the correspondence between the working voltage and the residual electric quantity is, namely, the difference exists in the time length used for each certain electric quantity under the same power consumption, so that the phenomenon of electric quantity jump easily occurs in the using process. Based on this, it can be determined whether the discharge curve of the battery needs to be updated, that is, whether the battery test function needs to be turned on, by the smoothness of the first discharge curve.

In this embodiment, under the condition that the smoothness of the first discharge curve is abnormal, that is, under the condition that the discharge curve of the battery needs to be updated, a reminding message for reminding a user to start the battery test function is output, so that the user starts the battery test function, and the battery is controlled to perform the discharge test, so as to obtain a second discharge curve of the battery.

The reminder information may be, for example, a notification prompting the user to turn on the battery health repair. For example, referring to fig. 2, the electronic device may provide a switch 21 for turning on the battery health repair, and the user may turn on the battery test function by clicking the switch 21 for turning on the battery health repair.

In some more specific examples, the battery detection method further includes a step of determining whether the smoothness of the discharge curve is abnormal, specifically including: steps S2100-S2400.

In step S2100, according to the first discharge curve, the information of the electric quantity of the battery at a plurality of sampling moments is obtained.

For example, the first discharge curve is a discharge curve within a power interval of 90% to 80%. The following table is a table showing the power information at a plurality of sampling moments obtained according to the first discharge curve.

Step S2200, obtaining the actual time length used by the battery for each consumption of the preset electric quantity according to the electric quantity information of the battery at a plurality of sampling moments.

The preset electric quantity can be, for example, 1% of the electric quantity, and can be determined according to actual needs, and is not particularly limited herein. For example, referring to the above table, the actual time period for each 1% of the battery to consume is obtained from the information of the battery's amount of electricity at a plurality of sampling times.

In step S2300, it is determined that the smoothness of the first discharge curve is normal if the actual duration satisfies the second preset condition.

Step S2400, determining that the smoothness of the first discharge curve is abnormal if the actual duration does not satisfy the second preset condition.

Wherein the second preset condition includes: the absolute value of the difference between the actual time length and the preset time length is smaller than or equal to a third threshold value.

The actual time length includes a plurality of time length data, and the actual time length meeting the second preset condition may be any time length data meeting the second preset condition.

The actual duration meeting the second preset condition may also be that the number of duration data meeting the second preset condition meets the requirement. For example, the preset duration is set to be greater than or equal to 10min, the third threshold is set to be 3min, referring to the table, and assuming that the absolute value of the difference between one or two duration data and the preset duration (10 min) is greater than 3min, the actual duration is considered to satisfy the second preset condition; assuming that the absolute value of the difference between the more than two duration data and the preset duration (10 min) is greater than 3min, the actual duration is not considered to meet the second preset condition.

Step S1300, obtaining a second discharging curve of the battery in a second manner when the battery test function is turned on.

The second discharging curve may be a discharging curve obtained by controlling the battery to perform a discharging test when the battery testing function is turned on. The second discharge curve is a discharge curve acquired in real time, and may reflect the current state of the battery.

In this step, the manner of acquiring the second discharge curve of the battery may be set according to the manner of acquiring the first discharge curve. That is, the first mode is a mode in which the battery is discharged in a partial power interval at a first preset discharge rate, and the second mode is a mode in which the battery is discharged in a full power interval. When the first mode is a mode that the battery is discharged in a full-power interval with a second preset discharge rate, the second mode is a discharge curve of the power interval with abnormal smoothness of the first discharge curve. Wherein, the first preset discharge multiplying power is smaller than the second preset discharge multiplying power.

The first mode is a mode that the battery is discharged in a partial electric quantity interval with a first preset discharge rate, and the second mode is a mode that the battery is discharged in a full electric quantity interval. Under the condition that the smoothness of the first discharge curve is abnormal, the fact that the smoothness of the discharge curve of the battery in other electric quantity intervals is possibly abnormal is indicated, and based on the fact, the second discharge curve is obtained in a mode that the battery is discharged in all electric quantity intervals, and therefore detection accuracy can be improved.

Taking a discharge curve of an electric quantity section with abnormal smoothness of the first discharge curve as an example, when the first mode is a mode that the battery discharges in the full electric quantity section with a second preset discharge rate. For example, the battery is controlled to operate at a discharge rate of 0.5C, and a first discharge curve in a 100% -0% electric quantity interval is obtained. Assume that the first discharge curve has an abnormal electric quantity interval of 90% -80%. The battery is controlled to charge according to the step charging strategy until the electric quantity of the battery reaches 90%, and the charging process is finished; and controlling the battery to discharge, ending the discharging process when the electric quantity of the battery is reduced to 80%, and obtaining a second discharging curve in the electric quantity interval of 90% -80%. Further, the curve segment of the standard discharge curve at 90% -80% can be replaced by the second discharge curve, so that the stored standard discharge curve can be updated.

According to the embodiment of the application, when the first mode is the mode that the battery discharges in the full electric quantity interval with the second preset discharge rate, the second mode is the discharge curve of the electric quantity interval with abnormal smoothness of the first discharge curve, so that the time for acquiring the second discharge curve can be shortened while the accuracy of detection is ensured, and the detection efficiency is improved.

In some embodiments of the present application, the step of obtaining a second discharge curve of the battery in a second manner may further comprise: steps S3100 to S3400.

Step S3100, in the process of controlling the battery to perform the discharge test, obtains the device status of the electronic device.

In step S3200, if the device status of the electronic device does not meet the third preset condition, the discharge test is terminated, and the first-stage discharge curve obtained at present is saved.

In step S3300, under the condition that the device status of the electronic device meets the third preset condition, the discharge test is continued, and a second stage discharge curve is obtained.

Wherein the third preset condition includes at least one of: the electronic equipment is in a charging state; the charging access type of the electronic equipment is a first type; the electronic device is in a normal operating state. In this embodiment, the first type may be a non-USB access type. The electronic device is in a normal operating state, i.e. the electronic device has not failed.

In the specific implementation, when the electronic device is not in a charging state or the charging access type of the electronic device is a non-USB access type in the process of controlling the battery to perform the discharging test, the user is indicated to use the electronic device, and at this time, the discharging test is terminated, and the currently obtained discharging curve of the first stage is stored. The first-stage discharge curve obtained at present can be stored in a storage unit of the electronic device, and the first-stage discharge curve can be sent to a server for backup through a communication module. When the electronic equipment is in a charging state and the charging access type of the electronic equipment is a non-USB access type, the user is not using the electronic equipment, and at the moment, the discharge test is continued, and a second stage discharge curve is obtained.

In a specific implementation, when the electronic device is not in a normal running state during the process of controlling the battery to perform the discharge test, for example, a processor of the electronic device fails, the discharge test is terminated, and a first-stage discharge curve which is obtained at present is stored. And when the fault of the electronic equipment is removed, namely the electronic equipment is in a normal running state, continuing the discharge test to obtain a second-stage discharge curve.

Step S3400, combining the first stage discharge curve and the second stage discharge curve to obtain a second discharge curve.

In specific implementation, the first stage discharge curve is fitted with the second stage discharge curve to obtain a second discharge curve.

Through steps S3100 to S3400, when the electronic device does not meet the third preset condition, the terminal discharge test can be performed, meanwhile, the first-stage discharge curve obtained at present can be saved, and when the electronic device meets the third preset condition, the second-stage discharge curve can be obtained when the discharge test is continued, so that normal use of the electronic device by a user is not affected, the situation that data are lost due to abnormal termination in the process of obtaining the second discharge curve can be avoided, and user experience is better.

In step S1400, the second discharge curve is uploaded to the server.

In the specific implementation, when the smoothness of the second discharge curve is normal, the second discharge curve is uploaded to a server for backup. Thus, data loss can be avoided, and user experience is better.

In some embodiments of the present application, after obtaining the second discharge curve, the battery detection method may further include: step S5100.

In step S5100, when the smoothness of the second discharge curve is normal, the stored standard discharge curve is updated by the second discharge curve.

The standard discharge curve may be a discharge curve stored in advance when the electronic device leaves the factory. For batteries of different models, corresponding standard discharge curves are preset. The standard discharge curve may be determined from experimental test data.

The step of determining whether the smoothness of the second discharge curve is abnormal is referred to as the step of determining whether the smoothness of the discharge curve is abnormal in the foregoing embodiment, and will not be described herein.

In the embodiment of the application, after the second discharge curve is obtained, under the condition that the smoothness of the second discharge curve is normal, the standard discharge curve of the stored battery is updated through the second discharge curve, so that the condition that the display electric quantity is inconsistent with the actual electric quantity due to drift of the discharge curve caused by aging of the battery can be avoided, and the accuracy of electric quantity display is improved.

In some embodiments of the present application, the battery detection method may further include: step S4100.

In step S4100, the battery is controlled to perform a discharge test at a preset temperature, and a second discharge curve corresponding to the preset temperature is obtained in a second manner.

The preset temperature may be an ambient temperature at which the electronic device is measured by a temperature sensor. In specific implementation, the temperature sensor is used for measuring the environmental temperature of the electronic equipment, a second discharge curve corresponding to the environmental temperature is obtained, and the second discharge curve is marked according to the environmental temperature.

The preset temperature may be a temperature set according to actual needs of the user. In specific implementation, the battery is controlled to perform discharge test at a preset temperature, a second discharge curve corresponding to the preset temperature is obtained, and the second discharge curve is marked according to the preset temperature.

In this embodiment, the step of updating the saved standard discharge curve by the second discharge curve may further include: and updating the stored standard discharge curve corresponding to the preset temperature through the second discharge curve to obtain an updated standard discharge curve.

In the embodiment of the application, the battery discharge curves corresponding to different temperatures can be updated in real time according to the environmental temperature change of the user, the electronic equipment can switch the curves according to the actual temperature, the use requirements of the user under different environments are met, the shutdown voltage can be accurately predicted under different temperature conditions, and low-power automatic shutdown is avoided.

The battery detection method will be described below with a specific example. Referring to fig. 3, the battery detection method includes the following steps.

Step S301, when the battery is operated at a discharge rate of 0.1C under the condition that the use state of the battery meets the first preset condition, a first discharge curve of a 100% -80% electric quantity interval is obtained.

Step S302, determining whether the smoothness of the first discharge curve is normal, if yes, returning to step S301, and if no, executing step S303.

The battery detection method will be described below with a specific example. Referring to fig. 4, the battery detection method includes the following steps.

Step S401, when the battery is operated at a discharge rate of 0.5C under the condition that the use state of the battery meets the first preset condition, a first discharge curve of a 100% -0% electric quantity interval is obtained.
