Description

Technical Field

[0001] The present application belongs to the field of battery health management, and specifically relates to a battery health detection method, device and electronic device for an electronic device. Background Art

[0002] Lithium-ion batteries are increasingly used in mobile devices such as mobile phones, laptops, tablets, digital cameras, etc. due to their high energy density and low environmental pollution.

[0003] However, lithium-ion batteries present different degrees of potential health risks during daily use without being discovered by users. For example, external force or internal foreign matter pierces the separator between the positive and negative electrodes, causing a battery short circuit; long-term overcharging or abnormally high current charging causes lithium ion dendrites to precipitate from the negative electrode, and the dendrites easily pierce the separator between the positive and negative electrodes of the battery, causing a micro short circuit in the battery; damaged battery appearance causes water vapor to penetrate the interior to cause electrochemical reactions, destroying the interface between the positive and negative electrode materials of the battery; for example, the battery works in high temperature and high pressure scenarios for a long time, resulting in an increase in the chemical impedance of the battery. All of the above may cause the battery's voltage drop (K value) per unit time to increase, affecting the battery life and even causing charging safety issues.

[0004] In this regard, although there are existing battery health detection methods that detect the battery health status by calculating the battery's K value, most of them passively calculate the battery's K value by keeping the battery in a fully charged or discharged state for a long time, and do not consider the complex power consumption scenarios of the electronic devices where the battery is located. The calculated K value is not accurate, resulting in low accuracy of the battery health status detection results. Summary of the invention

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0027] The following, in conjunction with the accompanying drawings, describes in detail the battery health detection method, device and electronic device of the electronic device provided in the embodiments of the present application through specific embodiments and their application scenarios.

[0028] <Example 1>

[0029] refer to Figure 1 , Figure 1 A battery health detection method for an electronic device provided in this embodiment is shown. The method can be applied to an electronic device, which may be a terminal device such as a mobile phone, a tablet, or a computer. The application scenario of this embodiment is that the electronic device is in a charging state, that is, the battery is in a charging state, so as to detect the charging and discharging performance of the battery according to the operating data of the battery during the charging and discharging process.

[0030] The battery health detection method of the electronic device of this embodiment includes the following steps S110 to S130:

[0031] S110: When the power level of the battery reaches a preset power level, adjust the power supply state of the electronic device to a charger power supply state.

[0032] The application scenario of this embodiment is that the electronic device is in a charging state, that is, the battery is in a continuously charging state. The preset power of this embodiment can be 80% of the full power when the battery is fully charged to ensure that the electronic device is in a sufficient power state. The preset power of this embodiment can also be 60% of the full power when the battery is fully charged to obtain the charging and discharging information of the battery under different power levels, so that the battery health detection results are more comprehensive and convincing.

[0033] In this embodiment, when the battery power reaches the preset power level, the power supply state of the electronic device is adjusted to the charger power supply state, the electronic device is powered directly by the voltage received by the charger, and the battery is stopped from charging. At the same time, the battery is not used to power the electronic device, but only to maintain the normal operation of the battery itself. It can be that when the battery power reaches 80% of the full power, the battery is stopped from charging, so that the battery is maintained at the current power level, and the voltage received by the charging port of the electronic device is used to maintain the system operation of the electronic device. In this case, the collected data such as the battery's own voltage and current can reflect the battery's own health data and will not be affected by the electronic device, so that the battery health detection results can be more accurate.

[0034] It is understandable that in this embodiment, the battery is controlled to be in a state of neither charging nor discharging, so as to avoid the battery being in a long-term charging state, which affects the battery life. In one scenario, the battery is in a long-term charging state mostly at night when the user is sleeping, and when the user is in a sleeping state, most programs in the electronic device are in a dormant state, and the power consumption of the electronic device is more stable. At this time, a health check of the battery can obtain a more accurate test result.

[0035] Therefore, in this embodiment, before adjusting the power supply state of the electronic device to the charger power supply state, it also includes generating a control instruction for the battery according to the user's sleep information. That is, before step S110, it also includes:

[0036] S1000: Acquire sleep information of the user, and generate a charge limit instruction when the sleep information indicates that the user is in a sleep state.

[0037] In one example, the user's sleep information may be the user's heart rate, breathing rate, body temperature, limb movements, and other physical signs that can be collected by a wearable device. The sleep information may be collected by a wearable device worn by the user, such as a smart watch, which can monitor the user's sleep data. For example, the smart watch collects that the user's heart rate during sleep is 65 beats / min; the user's breathing rate is 13 times / min; the user's wrist height during sleep is 9 cm, etc.

[0038] In one example, the user's sleep information includes the user being in a sleeping state and the user being in a non-sleeping state, wherein the non-sleeping state includes the user being in an awake state or a semi-awake state. It can be understood that when the user is in a sleeping state, there is no need to use the electronic device, and when the user is in a non-sleeping state, it can be considered that the user is about to use the electronic device. Therefore, when the sleep information indicates that the user is in a sleeping state, and the battery power has reached a preset power level at this time, a charge limit instruction can be generated to suspend the battery charging voltage input, adjust the power supply state of the electronic device to the charger power supply state, suspend the charging device from charging the battery, and protect the battery.

[0039] In one example, it can be determined that the user is in a sleeping state when the user's heart rate value is less than a first threshold value and the user's movement amplitude is less than a preset amplitude. In a feasible example, the first threshold value can be the heart rate value of a general user in a sleeping state collected through big data, for example, the first threshold value is 70 times / min. In a feasible example, the preset amplitude can be the maximum amplitude of the arm raised by a general user in a sleeping state collected through big data, and under this amplitude, the user can still be in a sleeping state. For example, the preset amplitude is 10cm.

[0040] In one example, when the user's heart rate value is greater than or equal to the first threshold value, and the user's motion amplitude is greater than or equal to the preset amplitude, the duration of the user's heart rate value greater than or equal to the first threshold value within the preset period, and the frequency of the user's motion amplitude greater than or equal to the preset amplitude within the preset period can be obtained to determine the user's sleep state. When the duration is greater than the first time, and the frequency of occurrence is greater than the preset value, it is determined that the user is in a non-sleep state. In an example, taking the first threshold value of 70 times / min, the first time is 5 minutes, the preset amplitude is 10cm, and the preset value is 5 times / min as an example, if the user's heart rate value H=75 times / min, and H continues to be 75 times / min for more than 5 minutes; and the user's motion amplitude G=12cm, that is, the user's motion amplitude is greater than 10cm, and the frequency of G=12cm within the preset period is greater than 5 times / min, it indicates that the user is in a non-sleep state. Otherwise, it is determined that the user is in a sleep state.

[0041] S1001. When the battery power reaches a preset power level, execute a charge limit instruction.

[0042] It can be understood that since the user's sleep state is a variable, that is, the user may change from a sleep state to a non-sleep state at any time, then the charge limit instruction of this embodiment can be generated when the battery power has not reached the preset power. However, if the battery power reaches the preset power and the user is still in a sleep state, the charge limit instruction can be executed to suspend the charging device from charging the battery to protect the battery.

[0043] S120: Acquire an actual discharge rate of the battery within a first period of time, and determine a reference threshold corresponding to the discharge rate of the battery.

[0044] In this embodiment, the first time may be a time set by the system of the electronic device, or a time set by the user through software. In one example, considering that the battery has a small self-discharge under normal circumstances and there is a voltage fluctuation within a certain range, if the first time of measuring the self-discharge of the battery is too short, there will be a certain error. Therefore, the first time in this embodiment is preferably greater than 5 minutes.

[0045] In this embodiment, the actual discharge rate of the battery within the first time can be obtained by the ratio of the voltage difference ΔV of the battery within the first time to the first time Δt1, for example, the discharge rate K=ΔV / Δt1.

[0046] In this embodiment, determining a reference threshold corresponding to the discharge rate of the battery may include the following steps S1201 and S1202:

[0047] S1201. Obtain a set reference model.

[0048] In this embodiment, the reference model may be a mapping function or a comparison table, etc., which is not limited here.

[0049] Taking the reference model as a comparison table as an example, we can establish a battery K value model under different cycle numbers, take a certain number of batteries with different cycle numbers, test the K values ​​under different power ranges, and use the maximum value of multiple sampling values ​​in each battery power range to obtain the maximum value of the K value in each battery power range. According to the maximum value of the K value, the reference threshold of the battery discharge rate in each power range is determined.

[0050] Take the battery with less than 100 cycles as an example, refer to Figure 2 , Figure 2This is a comparison table of the reference model of this embodiment for batteries with a cycle number of less than 100 times. In the range of battery power of 70% to 80%, five samples with battery numbers 1, 2, 3, 4, and 5 are set, and the time interval △t of the voltage difference is unified. The voltage differences corresponding to the five samples are △V1, △V2, △V3, △V4, and △V5. Then take the maximum value of △V1, △V2, △V3, △V4, and △V5 as the maximum Max value of the battery K value, that is, K Max =△Vmax1 / △t, therefore, when the number of battery cycles is within 100 times and the battery power range is 70% to 80%, the reference threshold value of the K value of the corresponding battery is K less than △Vmax1 / △t.

[0051] It should be noted that, during the modeling process, the battery power range and time interval △t can be optimized according to the actual battery chemical system.

[0052] In this embodiment, since the aging state of the battery, that is, the number of battery cycles, affects the discharge rate of the battery, the reference model of this embodiment can reflect the corresponding relationship between the number of battery cycles and the reference threshold of the discharge rate. Figure 2 As shown, the reference threshold value of the discharge rate of a battery with a battery cycle number within 100 times is K less than △Vmax1 / △t. In a feasible example, when the battery cycle number is between 100 and 300 times or between 300 and 500 times, the reference threshold value of the discharge rate of a battery may be K less than △Vmaxn / △t.

[0053] The model of this embodiment only needs to model the K value of the battery under different aging conditions. The modeling database is simple and easy to retrieve for comparison and analysis.

[0054] S1202: Acquire the actual battery cycle number of the battery, and obtain a reference threshold value corresponding to the discharge rate of the battery according to the actual battery cycle number and a set reference model.

[0055] In this embodiment, the battery cycle number x recorded by the processor of the electronic device can be read, and a pre-established K value comparison table can be retrieved at the same time, based on the battery cycle number x and the reference threshold value of the K value corresponding to the corresponding battery when the battery cycle number is x.

[0056] S130. Obtain a detection result indicating whether the battery is healthy based on a comparison result between the actual discharge rate and the reference threshold.

[0057] In this embodiment, obtaining a test result indicating whether the battery is healthy includes the following steps S1301 and S1302:

[0058] S1301. When the actual discharge rate is within a reference threshold, obtain a first detection result indicating battery health.

[0059] In an example, assuming that the actual discharge rate is 0.07 mV / h and the reference threshold is K<0.08 mV / h, then it can be determined that the actual discharge rate is within the reference threshold, and a first detection result indicating battery health is obtained.

[0060] S1302: When the actual discharge rate exceeds a reference threshold, obtain a second detection result indicating that the battery is unhealthy.

[0061] In one example, assuming that the actual discharge rate is 0.09 mV / h and the reference threshold is K<0.08 mV / h, then it can be determined that the actual discharge rate is within the reference threshold, and a first detection result indicating that the battery is unhealthy is obtained.

[0062] In this embodiment, an unhealthy battery may include that the battery is in a short circuit or micro-short circuit state, or the material of the battery is damaged.

[0063] Among them, in this embodiment, when the second test result indicating that the battery is unhealthy is obtained, a warning message can be generated to remind the user to go to the nearest service outlet for repair confirmation to improve the safety of battery use.

[0064] After obtaining the above results, if it is detected that the user is not in a sleeping state at this time, a resume charging instruction can be generated to continue charging the electronic device until the full charge is restored. When the battery is fully charged, if the electronic device is still connected to the charger, a limited charging instruction can continue to be generated to suspend the full charging of the electronic device to ensure the user's battery life experience.

[0065] In addition, the user's sleep information collected in this embodiment is only stored in the local application of the terminal device, and does not involve uploading, so there is no security risk.

[0066] In this embodiment, a wearable device can monitor the user's sleep behavior and obtain data from the wearable device, analyze and process the data, cut off the path for the battery to power the mobile phone without affecting the user's sleep state, adjust the charger to directly power the mobile phone, and put the battery in a self-consumption state to avoid the mobile phone consuming battery power. At the same time, the battery discharge rate K value is calculated, and the battery health status is determined by comparing the K value with the reference threshold, thereby further improving the detection accuracy.

[0067] <Example 2>

[0068] In one example, considering that the battery has a small self-discharge under normal circumstances and there is a voltage fluctuation within a certain range, if the first time of measuring the battery self-discharge is too short, the measured battery voltage difference △V may offset the fluctuating voltage, resulting in calculation errors and affecting the battery health status judgment. For example, 4 minutes after the battery power reaches the preset power, the user is in a non-sleep state, then the result measured by the above embodiment may be inaccurate at this time, then the battery health detection method for the user in the non-sleep state of this embodiment includes: generating a diversion instruction when the sleep information indicates that the user has changed from a sleep state to a non-sleep state.

[0069] In this embodiment, the shunt instruction is used to divide the charging voltage received by the electronic device into a first voltage and a second voltage, the first voltage is used to power the electronic device, and the power supply of the electronic device can provide power for the system operation of the electronic device, or power a running application, and the second voltage is used to charge the battery. This method can prevent the user from using the electronic device in a non-sleep state, which makes the battery discharge process complicated, thereby affecting the battery health detection.

[0070] That is, when the sleep information indicates that the user changes from a sleep state to a non-sleep state, in the above embodiment 1, the actual discharge rate of the battery within the first time is obtained, referring to Figure 3 , also includes:

[0071] S210: Obtain the duration of the electronic device being in a charger powered state.

[0072] In this embodiment, the duration of the electronic device being in the charger power supply state is, that is, the time difference between the moment when the battery power reaches the preset power and the moment when the user is in a non-sleep state. For example, at 3 a.m., the battery power reaches the preset power, and at 3:04 a.m., the user is in a non-sleep state. At this time, the electronic device generates a split current instruction, using the first voltage to power the electronic device and using the second voltage to charge the battery.

[0073] S220: When the duration is less than the second preset time, obtain charging information of the battery from a preset power level to a full power level.

[0074] In this embodiment, when the duration is less than the second preset time, that is, the time when the battery is neither charged nor discharged is too short, the measured battery voltage difference △V may offset the fluctuating voltage, resulting in calculation errors. Therefore, the actual discharge rate of the battery is calculated by obtaining the charging information of the battery from the preset power to the full power.

[0075] The charging information includes the first time, the amount of power provided by the second voltage to the battery during the first time, and the voltage change of the battery itself during the first time. It should be noted that the first time at this time is the time required for the battery to be fully charged from a preset power level. Calculating the discharge rate of the battery by changing the voltage within a large cycle can improve the accuracy of battery health status detection.

[0076] S230: Obtain an actual discharge rate of the battery within the first time according to the charging information.

[0077] According to S220, the first time is the time required for the battery to be fully charged from a preset power level. Assume that the start time of the first time is t2 and the end time is t3. The battery power is 80% at the start time and 100% at the end time. The actual power Q provided to the battery by the second voltage during the time from t2 to t3 is calculated by integration.

[0078] For example, refer to Figure 4 , use the real-time current a and time t to draw a dotted graph, with the horizontal axis being time t and the vertical axis being current a, to obtain the real-time current a=f(t). The shaded area enclosed by the drawn at curve and the horizontal axis is the actual amount of electricity Q provided to the battery by the second voltage, and the integral calculation is performed:

[0079]

[0080] Since the impedance R of the battery is relatively stable, the charge Q is equal to U / R*t, that is, the second voltage U=(F(t3)-F(t2))*R / (t3-t2).

[0081] It can be understood that the second voltage provided to the battery is the actual voltage given to the battery, and through the reference model described in Example 1, a reference voltage value of the battery in the range of a preset power level (for example, 80%) to a full power level can be obtained. Assuming that the reference voltage value is △V30, the difference between the actual voltage and the reference voltage value is the voltage consumed by the self-discharge of the battery, that is, the actual discharge rate of the battery K = (U-△V30) / (t3-t2).

[0082] When the sleep information indicates that the user has changed from a sleeping state to a non-sleeping state, after calculating the actual discharge rate of the battery, the actual discharge rate of the battery in the first time is compared with the corresponding reference threshold in the reference model to obtain a detection result indicating whether the battery is healthy, which is step S130 of the first embodiment.

[0083] This embodiment can avoid the problem of deviation in battery health detection results when the user's sleep state lasts for a short period of time. During the charging process, the charging current of the charger is shunted to ensure that the battery is fully charged without affecting the user experience. At the same time, the battery self-discharge value can be accurately obtained through integral calculation to judge the battery health status.

[0084] It should be noted that the battery health detection method for an electronic device provided in the embodiment of the present application can be executed by a battery health detection device for an electronic device, or by a control module in the battery health detection device for the electronic device for executing the battery health detection method for loading the electronic device. In the embodiment of the present application, the battery health detection method for an electronic device provided in the embodiment of the present application is explained by taking the battery health detection device for an electronic device executing the battery health detection method for loading the electronic device as an example.

[0085] refer to Figure 5 , a battery health detection device for an electronic device is provided, the device comprising:

[0086] The control module 501 is used for adjusting the power supply state of the electronic device to a charger power supply state when the power of the battery reaches a preset power supply state, wherein in the charger power supply state, the battery is suspended from supplying power to the electronic device;

[0087] A data processing module 502 is used to obtain an actual discharge rate of the battery within a first period of time and determine a reference threshold value corresponding to the discharge rate of the battery;

[0088] The health detection module 503 is used to obtain a detection result indicating whether the battery is healthy according to a comparison result between the actual discharge rate and the reference threshold.

[0089] In one example, the data processing module is further used to:

[0090] Acquire a set reference model; wherein the reference model reflects the corresponding relationship between the number of battery cycles of the battery and the reference threshold of the discharge rate;

[0091] The actual battery cycle number of the battery is obtained, and a reference threshold corresponding to the discharge rate of the battery is obtained according to the actual battery cycle number and a set reference model.
