Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms "first" and "second," and the like, in the description and in the claims of the present application, are used for distinguishing between different objects and not for describing a particular order of the objects. For example, the first charging current and the second charging current, etc. are for distinguishing different charging currents, and are not for describing a specific order of charging currents.

It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

Along with wearable equipment is more miniaturized, battery capacity is difficult to improve because of the limitation of battery space, but the function of wearable equipment is more and more abundant, and the endurance of wearable equipment is poor more and more. Especially in the telephone and watch industry, the front and back cameras, video chat, photographing, video recording and other high-power consumption applications are more and more owned, the standby power consumption is closer to that of a smart phone, but the maximum battery capacity does not exceed 1000 milliampere hours (mAh), and is only one fifth of the battery of the mobile phone. And at present when charging wearable equipment, can adopt the charging mode of constant current earlier then constant voltage usually, specifically as follows: the method comprises the steps of firstly using a larger charging current to carry out constant current charging, using the rated voltage of the battery to carry out constant voltage charging after the voltage of the battery reaches the rated voltage of the battery, and stopping charging until the charging current of the battery is less than or equal to a charging cut-off current corresponding to the rated voltage of the battery. Due to the small battery capacity of the wearable device, the charging cutoff current is too small.

For example, assume that the wearable device has a battery specification of 800mAh/4.45V, i.e., a battery capacity of 800mAh and a battery rated voltage of 4.45V. Usually, the charging current is 0.9 times the battery capacity (the maximum charging current allowed by the battery is 0.9 times the battery capacity), i.e. 800 × 0.9 equals 720mA, and the charging cutoff current corresponding to 4.45V is 0.02 times the battery capacity, i.e. 800 × 0.02 equals 16mA, i.e. the battery of the wearable device needs to be charged until the charging current of the battery is less than or equal to 16mA, so as to indicate that the battery of the wearable device is fully charged. Fig. 1 shows a graph of voltage and current changes during charging, where a curve 101 is a current change curve, a curve 102 is a voltage change curve, a curve 101 is a change curve of first level and then descending, and a curve 102 is a change curve of first rising and then level. In the constant current phase, namely from 0 to t1, charging the battery of the wearable device according to the constant current of 720mA, wherein the voltage of the battery of the wearable device gradually rises from 0 until the voltage of the battery reaches 4.45V, and the constant current phase is ended; then, the battery of the wearable device enters a constant voltage phase, that is, when the time is from t1 to t2, the battery of the wearable device is charged according to a constant voltage of 4.45V, since the charging voltage of the battery is kept constant, but the battery voltage is still rising, as the difference between the charging voltage and the battery voltage continuously rises, the charging current of the wearable device gradually falls from 720mA, and experiments show that when the charging current of the wearable device is reduced to 60mA, the charging cannot be continued, and at this time, when 60mA is greater than 16mA, the battery of the wearable device is not fully charged.

To sum up, the main problem that exists of battery charging process of present wearable equipment is: the cut-off current of the full charge of the small-capacity battery is very small, and at present, charging equipment with very small cut-off current is basically not available in the market.

Generally, a small-capacity battery requires a charge cutoff current of less than 0.02C to fully charge the battery.

For an exemplary 800mAh battery, the cut-off current required for full charge is 0.02C, i.e. 16mAh, and the cut-off current for charging by the current charging equipment in the market is generally above 50mA, i.e. the cut-off condition required for full charge is not reached.

A charging chip with small cut-off current is additionally arranged in part of wearable equipment on the market at present, so that the cost of the product is increased, and the internal space of the wearable equipment is occupied.

In order to solve the above problem, embodiments of the present application provide a charging method for a wearable device, and a storage medium, where the wearable device may first perform constant current charging (i.e., a maximum charging current allowed by a battery cell) by using a first charging current, when a voltage of a battery rises to a rated voltage of the battery, the first charging current is reduced to a second charging current to continue the constant current charging, when the voltage of the battery continues to rise to a target voltage, the target voltage is used to perform constant voltage charging, and when the charging current is less than or equal to a cutoff current corresponding to the target voltage, the charging is stopped; and the cutoff current corresponding to the target voltage is greater than the cutoff current corresponding to the rated voltage of the battery. In the scheme, the wearable device can perform two-stage constant-current charging and one-stage constant-voltage charging, and the charging voltage during constant-voltage charging is increased, so that the cut-off current of the battery can be increased, and the battery charging time of the wearable device can be effectively shortened; moreover, the wearable device is charged by adopting larger voltage and higher cut-off current, and the cut-off current can be increased under the condition that a charging chip is not additionally added, so that the wearable device can be fully charged by using common charging equipment, and the utilization rate of the battery is effectively increased.

The wearable equipment that this application embodiment relates to can be for intelligent wrist-watch, intelligent bracelet, wrist-watch phone, intelligent foot ring, intelligent earrings, intelligent necklace, intelligent earphone etc. and this application embodiment does not limit.

An execution main body of the charging method of the wearable device provided in the embodiment of the present application may be the wearable device, or may also be a functional module and/or a functional entity capable of implementing the charging method of the wearable device in the wearable device, which may be specifically determined according to actual use requirements, and the embodiment of the present application is not limited. The following takes a wearable device as an example, and an exemplary description is provided for a charging method of the wearable device provided in the embodiments of the present application.

As shown in fig. 2, an embodiment of the present application provides a charging method for a wearable device, which may include the following steps:

201. and carrying out constant current charging on the battery of the wearable device by adopting the first charging current.

In this embodiment, the wearable device may first perform constant current charging on a battery of the wearable device by using the first charging current until a battery voltage of the wearable device reaches a battery rated voltage.

It should be noted that the battery rated voltage is a fixed parameter of the battery of the wearable device, and is already set to a fixed value when the battery cell of the battery is produced.

Optionally, the battery rated voltage of the wearable device may be greater than or equal to 4.2V and less than or equal to 4.6V, such as 4.2V, 4.45V, and the like.

Optionally, a ratio between the first charging current and a battery capacity of the wearable device may be less than or equal to 0.9; the battery capacity of the wearable device is a fixed parameter of the battery of the wearable device, and is set to be a fixed value when the battery cell of the battery is produced, and the maximum charging rate is also determined when the battery cell is produced.

For example, assuming that the battery capacity of the wearable device is 800mAh, and the ratio between the first charging current and the battery capacity of the wearable device is 0.9, the first charging current is 800 × 0.9 — 720 mA.

In the embodiment of the application, when the battery of the wearable device is charged by adopting the first charging current, the battery current is kept unchanged, and the battery voltage is continuously increased until the battery voltage reaches the rated voltage of the battery.

For example, as shown in fig. 3, a graph of voltage and current changes during charging is shown, where a curve 301 is a current change curve, a curve 302 is a voltage change curve, a curve 301 is a change curve of first level and then descending, and a curve 302 is a change curve of first rising and then level. During the first constant current phase, i.e. from 0 to t1, the battery of the wearable device is charged with a constant current of 720mA, and the voltage of the battery of the wearable device gradually rises from 0 until the voltage of the battery reaches 4.45V, at which time the first constant current phase ends.

Optionally, the constant current charging of the battery of the wearable device by using the first charging current may specifically include: the method comprises the steps that constant current charging is conducted on the wearable device through a first charging current, and the initial charging power of the wearable device is detected; and if the initial charging power is greater than the charging safety power, performing constant-power charging on the battery of the wearable device by using the charging safety power until the battery voltage of the wearable device reaches the rated voltage of the battery.

In the embodiment of the application, when the wearable device is charged with the first charging current at a constant current, the initial charging power of the battery of the wearable device can be detected, and if the initial charging power is greater than the charging safety power, it is shown that the current charging power is higher, and there is a certain risk, the wearable device can charge the battery of the wearable device with the charging safety power at a constant power until the voltage of the battery of the wearable device reaches the rated voltage of the battery.

It should be noted that the charging safety power that the wearable device can bear is set when the battery cell is produced.

For example, as shown in fig. 4, a curve 401 is a current variation curve, a curve 402 is a voltage variation curve, a curve 401 is a continuously decreasing variation curve, and a curve 402 is a first increasing and then horizontal variation curve. In the constant power phase, i.e. from 0 to t1, the battery current of the wearable device decreases and the battery voltage of the wearable device increases, so as to ensure that the product of the battery current and the battery voltage of the wearable device, i.e. the power of the wearable device remains unchanged until the battery voltage of the wearable device increases to the rated voltage of the battery.

In this optional implementation, the wearable device may perform constant power charging according to the initial charging power, which may ensure that the charging power of the wearable device is kept within a safe range and does not cause damage to the wearable device and the battery of the wearable device.

202. And adjusting the first charging current into a second charging current, and continuously carrying out constant current charging on the battery by adopting the second charging current.

In this embodiment, the wearable device may adjust the first charging current to the second charging current after the first constant current phase is ended, and continue to perform constant current charging on the battery with the second charging current until the battery voltage rises from the battery rated voltage to the target voltage.

And the second charging current is less than the first charging current, and the target voltage is greater than the rated voltage of the battery.

The off-current corresponding to the target voltage is larger than the off-current corresponding to the rated voltage of the battery.

Optionally, each charging voltage may correspond to an off-current, and when the charging voltage is higher, the corresponding off-current is also higher, that is, the charging time is shorter.

It should be noted that, when the wearable device adjusts the first charging current to the second charging current, the battery voltage of the wearable device will also drop synchronously due to the drop of the charging current (the drop is caused by the internal resistance of the battery itself, and the virtual voltage generated during the charging process is the product of the charging current and the internal resistance), and then rises with the constant current charging.

For example, as shown in fig. 3, a curve 301 is a current variation curve, a curve 302 is a voltage variation curve, the curve 301 is a horizontal-first-then-descending variation curve, and the curve 302 is a horizontal-first-then-ascending variation curve. Assuming that the second charging current is 400mA and the target voltage is 4.48V, the charging current of the battery of the wearable device decreases from 720mA to 400mA in the second constant current phase, i.e., the time from t1 to t2, and the voltage of the battery of the wearable device also decreases, and when the battery of the wearable device is charged at the constant current of 400mA, the voltage of the battery of the wearable device starts to gradually increase until the voltage of the battery reaches 4.48V, and the second constant current phase ends.

Optionally, the adjusting the first charging current to a second charging current, and the constant current charging of the battery is continued by using the second charging current, which may specifically include: adjusting the first charging current to a third charging current, and adopting the third charging current to continuously perform constant-current charging on the battery until the voltage of the battery is increased from the rated voltage of the battery to the first charging voltage, wherein the third charging current is smaller than the first charging current; and adjusting the third charging current to be a second charging current, and continuously carrying out constant-current charging on the battery by adopting the second charging current until the voltage of the battery is increased from the first charging voltage to the target voltage, wherein the second charging current is smaller than the third charging current.

In this embodiment, the wearable device may adjust the first charging current to the third charging current for constant current charging, and then adjust the third charging current to the second charging current for constant current charging.

The first charging current is greater than the third charging current, and the third charging current is greater than the second charging current; constant current charging is carried out by adopting a third charging current, and the voltage of the battery needs to be increased from the rated voltage of the battery to the first charging voltage; and performing constant current charging by using a second charging current, wherein the voltage of the battery needs to be increased from the first charging voltage to a target voltage.

The off-current corresponding to the rated voltage of the battery is smaller than the off-current corresponding to the first charging voltage, and the off-current corresponding to the first charging voltage is smaller than the off-current corresponding to the target voltage.

For example, as shown in fig. 5, a curve 501 is a current variation curve, a curve 502 is a voltage variation curve, a curve 501 is a horizontal-first-then-descending variation curve, and a curve 502 is a horizontal-first-then-ascending variation curve. Assume that the third charging current is 560mA, the second charging current is 400mA, the first charging voltage is 4.46V, and the target voltage is 4.48V. Then in the second constant current phase, i.e. from t1 to t2, the charging current of the battery of the wearable device decreases from 720mA to 560mA, at which time the voltage of the battery of the wearable device decreases on the basis of 4.45V, when the battery of the wearable device is charged with the constant current of 560mA, the voltage of the battery of the wearable device starts to gradually increase until the voltage of the battery reaches 4.46V, at which time the second constant current phase ends; and in the third constant current phase, namely time is t2-t3, the charging current of the battery of the wearable device is reduced from 560mA to 400mA, the voltage of the battery of the wearable device is reduced on the basis of 4.46V, when the battery of the wearable device is charged according to the constant current of 400mA, the voltage of the battery of the wearable device starts to gradually rise until the voltage of the battery reaches 4.48V, and the third constant current phase is ended.

Optionally, in the optional implementation manner, a process of performing two-stage constant current charging after performing the constant current charging by using the first charging current is shown. The wearable device can perform the N-segment constant current charging process again after performing the constant current charging by using the first charging current, the charging current during each constant current charging is gradually reduced, the battery voltage after each constant current charging is gradually increased, and N is an integer greater than or equal to 1.

Through above-mentioned optional implementation, wearable equipment can increase the number of times that the constant current charges, through the mode that constantly reduces charging current, improves charging voltage, can improve the cutoff current that charging voltage corresponds like this, shortens wearable equipment's charging time.

203. And carrying out constant voltage charging on the battery of the wearable device by adopting the target voltage.

In this application embodiment, wearable equipment is after constant current charging, and battery voltage has reached target voltage, and wearable equipment can adopt target voltage to carry out constant voltage charging to wearable equipment's battery this moment, and the charging current of wearable equipment's battery can descend gradually this moment.

204. And stopping charging when the charging current of the battery is less than or equal to the cut-off current corresponding to the target voltage.

In this embodiment of the application, in the constant voltage phase, the charging current of the battery of the wearable device may gradually decrease, and when the charging current of the battery is less than or equal to the cutoff current corresponding to the target voltage, it may be indicated that the battery of the wearable device is fully charged, and then the charging is stopped.

For example, as shown in fig. 3, a curve 301 is a current variation curve, a curve 302 is a voltage variation curve, the curve 301 is a horizontal-first-then-descending variation curve, and the curve 302 is a horizontal-first-then-ascending variation curve. Assuming that the target voltage is 4.48V and the corresponding cutoff current is 0.15 × 800 — 120mA, the battery of the wearable device is charged at a constant voltage of 4.48V during the constant voltage phase, i.e., from t2 to t3, and the battery current of the wearable device starts to decrease until the charging current of the battery reaches 120mA, at which time the constant voltage phase ends.

The embodiment of the application provides a charging method of wearable equipment, the wearable equipment can firstly adopt a first charging current to carry out constant current charging, when the voltage of a battery rises to the rated voltage of the battery, the first charging current is reduced to a second charging current to continue the constant current charging, when the voltage of the battery continues to rise to a target voltage, the target voltage is adopted to carry out constant voltage charging, and when the charging current is less than or equal to a cut-off current corresponding to the target voltage, the charging is stopped; and the cutoff current corresponding to the target voltage is greater than the cutoff current corresponding to the rated voltage of the battery. In the scheme, the wearable device can perform two-stage constant-current charging and one-stage constant-voltage charging, and the charging voltage during constant-voltage charging is increased, so that the cut-off current of the battery can be increased, and the battery charging time of the wearable device can be effectively shortened; moreover, the wearable device is charged by adopting larger voltage and higher cut-off current, and the cut-off current can be increased under the condition that a charging chip is not additionally added, so that the wearable device can be fully charged by using common charging equipment, and the utilization rate of the battery is effectively increased.

As an optional implementation manner, the constant-voltage charging is performed on the battery of the wearable device by using the target voltage, and when the charging current of the battery is less than or equal to the cutoff current corresponding to the target voltage, the charging is stopped, which specifically includes: carrying out constant voltage charging on a battery of the wearable device by adopting the target voltage, and detecting the charging current of the battery in real time; when the charging current of the battery reaches a preset current threshold value, performing constant-voltage charging on the battery of the wearable device by adopting a second charging voltage, wherein the second charging voltage is greater than a target voltage; and stopping charging when the charging current of the battery is less than or equal to the cut-off current corresponding to the second charging voltage.

In this embodiment of the application, after the battery of the wearable device is charged at the constant voltage by using the target voltage, when the charging current of the battery reaches the preset current threshold, the target voltage is adjusted to the second charging voltage and the constant voltage charging is performed, until the charging current of the battery is less than or equal to the cutoff current corresponding to the second charging voltage, the charging is stopped.

Wherein the second charging voltage is greater than the target voltage; the cutoff current corresponding to the second charging voltage is greater than the cutoff current corresponding to the target voltage.

For example, as shown in fig. 6, a curve 601 is a current variation curve, a curve 602 is a voltage variation curve, a curve 601 is a horizontal-first-then-descending variation curve, and a curve 602 is a horizontal-first-then-ascending variation curve. Assume that the preset current threshold is 230mA, the target voltage is 4.48V, the second charging voltage is 4.50V, and the cutoff current corresponding to the second charging voltage is 0.17 × 800 ═ 136 mA. Then in the first constant voltage phase, i.e. at time t2-t3, the battery of the wearable device is charged at a constant voltage of 4.48V, and the battery current of the wearable device starts to decrease until the charging current of the battery reaches 230mA, and the first constant voltage phase ends; during the second constant voltage phase, i.e. at time t2-t3, the voltage of the battery of the wearable device rises from 4.48V to 4.50V, at which time the charging current of the wearable device rises on the basis of 230mA, and when the battery of the wearable device is charged at a constant voltage of 4.50V, the charging current of the wearable device starts to gradually decrease until the charging current reaches 136mA, at which time the second constant voltage phase ends.

Optionally, in the above optional implementation, a process of performing constant voltage charging after performing constant voltage charging with the target voltage is shown.

701. and carrying out a plurality of charging tests on the battery of the wearable device by adopting the first test current, a plurality of different second test currents and a plurality of different test voltages.

In this embodiment, the wearable device may perform a cell test before leaving the factory to obtain an ideal second charging current and a target voltage through the test, so as to obtain a corresponding cutoff current.

Optionally, the battery of the wearable device is subjected to multiple charging tests by using the first test current, the multiple different second test currents, and the multiple different test voltages, which may specifically include:

performing constant-current charging on a battery of the wearable device by adopting a first test current until the voltage of the battery of the wearable device reaches the rated voltage of the battery; adjusting the first test current to a second test current, and adopting the second test current to continuously perform constant current charging on the battery until the voltage of the battery is increased from the rated voltage of the battery to the test voltage; carrying out constant voltage charging on a battery of the wearable equipment by adopting the test voltage, and stopping charging after the battery capacity of the wearable equipment reaches the rated battery capacity; determining the charging current when the charging is stopped as a cut-off current corresponding to the second test current and the test voltage; and adjusting the second test current and the test voltage, and performing constant current charging on the battery of the wearable device by adopting the first test current again until the battery voltage of the wearable device reaches the rated voltage of the battery.

And the second test current is less than the first test current, and the cut-off current corresponding to the test voltage is greater than the cut-off current corresponding to the rated voltage of the battery.

It should be noted that the ratio between the first test current and the battery capacity of the wearable device may be less than or equal to 0.9, and the battery capacity of the wearable device is a fixed parameter of the battery of the wearable device, and is already set to a fixed value when the battery cell of the battery is produced.

For example, assuming that the battery capacity of the wearable device is 800mAh, and the ratio between the first test current and the battery capacity of the wearable device is 0.9, the first test current is 800 × 0.9 — 720 mA.

In the embodiment of the application, the steps of each charging test performed by the battery of the wearable device are the same, the battery of the wearable device is charged by adopting a first test current, at the moment, the current of the battery is kept unchanged, and the voltage of the battery is continuously increased until the voltage of the battery reaches the rated voltage of the battery; adjusting the first test current to a second test current, and adopting the second test current to continuously perform constant current charging on the battery until the voltage of the battery is increased from the rated voltage of the battery to the test voltage; and then, carrying out constant voltage charging on the battery of the wearable device by adopting the test voltage, and stopping charging when the battery capacity of the wearable device reaches the rated battery capacity.

The first test current is the same in each charging test, and the values of at least one parameter in the second test current and the test voltage are different, namely the second test current is the same and the test voltage is different; or the second test currents are different, and the test voltages are the same; alternatively, the second test current is different and the test voltage is also different.

For example, assume that the wearable device has a rated battery capacity of 780 mAh. First charging test: the first test current is 720mA, the second test current is 400mA, the test voltage is 4.46V, and the charging current is 110mA when the battery capacity reaches 780 mAh; and (3) second charging test: the first test current is 720mA, the second test current is 360mA, the test voltage is 4.46V, and the charging current is 90mA when the battery capacity reaches 780 mAh; third charging test: the first test current is 720mA, the second test current is 380mA, the test voltage is 4.47V, and the charging current is 105mA when the battery capacity reaches 780 mAh; fourth charging test: the first test current is 720mA, the second test current is 420mA, the test voltage is 4.48V, and the charging current is 136mA when the battery capacity reaches 780 mAh; fifth charging test: the first test current is 720mA, the second test current is 400mA, the test voltage is 4.48V, and the charging current is 120mA when the battery capacity reaches 780 mAh.

Optionally, in each adjustment process of the second test current and the test voltage, the value of the second test current may be fixed, the value of the test voltage may be adjusted continuously, and then the value of the test voltage may be fixed, and the value of the second test current may be adjusted continuously; the values of the second test current and the test voltage may also be adjusted simultaneously.

Optionally, during each adjustment of the second test current and the test voltage, the adjustment may be performed according to a fixed variation, for example, the second test current may be increased or decreased by 20mA each time, or the test voltage may be increased or decreased by 0.01V each time.

Through the optional implementation mode, the wearable device can perform multiple charging tests on the battery of the wearable device by adopting the first test current, the multiple different second test currents and the multiple different test voltages, and the charging current when the battery capacity of the wearable device reaches the rated battery capacity in each charging test is determined as the cut-off current of the charging test. By the scheme, different second test currents and test voltages and corresponding relations between the cut-off currents can be obtained, so that the wearable device can be directly measured whether to be full or not through the cut-off currents in the subsequent charging process.

702. The charging time of each charging test of the battery of the wearable device is detected and recorded.

In this embodiment, the wearable device may calculate, at the time of the charging test, a charging time by using the synchronous start timer, where the charging time is a time from starting constant current charging with the first test current to when the battery capacity of the wearable device reaches the rated battery capacity.

703. And determining the second test current and the test voltage corresponding to the charging test with the shortest charging time as the second charging current and the target voltage.

In this embodiment of the application, the wearable device may sequence the charging time of each charging test, select the second test current and the test voltage corresponding to the charging test with the shortest charging time, determine the second test current and the test voltage as the second charging current and the target voltage, and perform subsequent charging.

It should be noted that, since the charging current at the time of stopping charging is determined as the cutoff current corresponding to the second test current and the test voltage at each time of the charging test, in the charging process of the wearable device, a certain second test current and a certain test voltage in the charging test are used for charging, and when the charging current drops to the cutoff current corresponding to the second test current and the test voltage in the charging test, that is, the wearable device is fully charged, then the charging of the battery of the wearable device may be stopped at this time.

For example, assuming a rated battery capacity of 780mAh, the wearable device is tested five times before leaving the factory, which is the first charging test: the first test current is 720mA, the second test current is 400mA, the test voltage is 4.46V, the charging current is 110mA when the battery capacity reaches 780mAh, and the charging time is 50 minutes; and (3) second charging test: the first test current is 720mA, the second test current is 360mA, the test voltage is 4.46V, the charging current is 90mA when the battery capacity reaches 780mAh, and the charging time is 61 minutes; third charging test: the first test current is 720mA, the second test current is 380mA, the test voltage is 4.47V, the charging current is 105mA when the battery capacity reaches 780mAh, and the charging time is 54 minutes; fourth charging test: the first test current is 720mA, the second test current is 420mA, the test voltage is 4.48V, the charging current is 136mA when the battery capacity reaches 780mAh, and the charging time is 45 minutes; fifth charging test: the first test current is 720mA, the second test current is 400mA, the test voltage is 4.48V, the charging current is 120mA when the battery capacity reaches 780mAh, and the charging time is 48 minutes. The detection shows that the time of the fourth charging test is shortest, so that when the wearable device is charged after leaving the factory, parameters of 720mA of the first test current, 420mA of the second test current and 4.48V of the test voltage can be adopted for charging, and when the charging current is reduced to 136mA, the current wearable device can be indicated to be fully charged, and then the charging can be stopped.

Optionally, before determining a second test current and a test voltage corresponding to the charge test with the highest battery capacity as the second charge current and the target voltage, the wearable device may further detect a battery electric core of the wearable device; and if the battery cell is detected to be free from the abnormal phenomenon, determining a second test current and a test voltage corresponding to the charging test with the highest battery capacity as a second charging current and a target voltage.

Wherein, the abnormal phenomenon comprises: and (3) when the humidity of the battery is greater than a preset humidity threshold value, the material is dissolved, and the discharge capacity of the battery is less than one of the preset discharge capacity threshold values.

In this embodiment of the application, the wearable device may detect whether an abnormal phenomenon exists in a battery cell of the wearable device after performing a plurality of charging tests on the battery, and if the abnormal phenomenon does not exist in the battery cell, it indicates that a second test current and a test voltage for performing the charging test are within a safety range of the battery cell, and then the wearable device may determine the second test current and the test voltage corresponding to the charging test with the highest battery capacity as the second charging current and the target voltage.
