Description

Mobile power supply testing method and device, computer equipment and storage medium

Technical Field

The present application relates to the field of power testing technologies, and in particular, to a method and apparatus for testing a mobile power supply, a computer device, and a storage medium.

Background

A portable power source, also called a portable charger or an external power source, is a portable battery device, usually in a portable small form factor, and is intended to provide power support for mobile electronic devices such as smart phones, tablet computers, notebook computers, and the like. Its core function is to store electrical energy and release it as current when needed to meet the charging needs of the user equipment.

In the use process of the mobile power supply, the number of charge and discharge cycles of the internal battery or the battery pack can increase with time, so that the physical loss of the internal materials of the battery or the battery pack is caused. And chemical reactions inside the battery or the battery pack may change over time, resulting in a decrease in charge capacity of the battery or the battery pack, and the like. The above causes the internal battery or battery pack of the power supply to gradually lose its original performance with the lapse of time, a phenomenon called aging of the mobile power supply.

Aging of the mobile power supply may result in reduced power storage capacity, reduced charging speed, reduced battery life, overheating of the power supply, or other safety issues. Therefore, when the aging degree of the mobile power supply is high, the mobile power supply needs to be replaced for use. However, in the process of using the mobile power supply by the ordinary user, no related professional equipment or program is usually available for testing the aging degree of the mobile power supply, and only the discharge condition of the mobile power supply can be estimated. Therefore, a more accurate method is needed to realize the aging degree test of the mobile power supply.

The embodiment discloses a testing method of a mobile power supply, referring to fig. 1, comprising the following steps S110-S150:

s110, discharging the power to be tested through the test power until the power to be tested enters a full power state, and determining the residual capacity of the test power.

The test method of the mobile power supply disclosed by the embodiment of the application is applied to a test system, and the test system comprises a test power supply, a timing device and a power supply, wherein the timing device is used for recording time. The test power supply is used for assisting in carrying out aging degree test on the power supply to be tested, and the rated capacity of the test power supply is the same as that of the power supply to be tested. A test power supply is understood here to mean a mobile power supply with essentially no charge-discharge cycles and negligible battery ageing.

When testing, firstly, determining that the test power supply is in a full-charge state, namely, the full-charge state of the test power supply, which means that the test power supply or the battery is fully charged, and the electric quantity of the battery reaches the maximum value of rated capacity. And meanwhile, determining that the power supply to be tested is in an empty state, wherein the empty state is that the electric quantity of the power supply to be tested is in a zero state, which means that the electric quantity of the power supply or the battery to be tested is exhausted and the power cannot be supplied to the outside.

And then connecting the test power supply and the power supply to be tested, enabling the power supply to be tested to be in a discharging state, enabling the test power supply to be in a charging state, and discharging the power supply to be tested through the test power supply. In general, the mobile power sources each include a charging port and a discharging port. In order to realize the discharge of the test power supply to the power supply to be tested, the discharge port of the test power supply is required to be connected with the charge port of the power supply to be tested through the related power line so as to realize the discharge of the test power supply to the power supply to be tested. When the test power supply cannot discharge the power supply to be tested, the discharge process is ended, and the discharge quantity of the test power supply is measured. This can be achieved by recording the difference in charge before and after the discharge of the power supply. Currently, most mobile power supplies are provided with power display, including detailed percentage display. Therefore, the discharge amount of the test power supply can be obtained by multiplying the rated capacity of the test power supply according to the percentage difference before and after charging and discharging. The discharge amount of the test power supply can be simply determined as the residual electric quantity of the power supply to be tested.

And determining that the test power supply is in a full power state and the power supply to be tested is in an empty power state. This ensures that the power supply to be tested is charged from a completely empty state during discharge. And discharging the power supply to be tested through the test power supply until the power supply to be tested enters a full-power state, and determining the discharge capacity of the test power supply. This step allows to know the behavior of the power supply to be tested during discharge and the amount of power it needs from the empty to the full state. The residual capacity of the power supply to be tested can be accurately estimated by simulating the discharge condition in the actual use process, so that the power supply to be tested is used for reflecting the aging degree of the power supply to be tested.

In order to test the residual electric quantity of the power supply to be tested more accurately, the power supply to be tested can be subjected to multiple times of discharge, so that the residual electric quantity of the power supply to be tested is determined according to multiple times of discharge results.

Specifically, the power supply to be tested is in a full-power state every time, the power supply to be tested is in a charging state, and then the power supply to be tested is discharged through the power supply to be tested until the power supply to be tested enters the full-power state. And recording the discharge quantity of the test power supply in each discharge process to obtain a plurality of discharge quantities. And then, averaging the multiple discharge amounts to obtain an average discharge amount. And finally, setting the average discharge capacity as the residual capacity of the power supply to be tested.

By discharging for a plurality of times and calculating the average discharge amount, errors can be reduced, the accuracy of data can be improved, and the residual capacity of the power supply to be tested can be reflected more accurately. And meanwhile, by calculating the average value, abnormal fluctuation of individual data can be eliminated, and more stable residual capacity data can be obtained.

S120, determining the capacity reduction amount of the power supply to be tested according to the residual capacity and the rated capacity of the power supply to be tested.

In the foregoing, the test power source and the power source to be tested are mobile power sources with the same rated capacity, and the remaining capacity of the power source to be tested, that is, the maximum capacity of the whole power source to be tested after the battery or the battery pack of the power source to be tested is used for a long time, has been calculated through step S110. And according to the difference between the rated capacity and the residual capacity, the capacity reduction of the power supply to be tested can be obtained, namely the capacity reduction of the battery or the battery pack caused by aging when the power supply to be tested is used for a long time.

S130, respectively charging the test power supply and the power supply to be tested by adopting the same power supply, and determining a first charging speed of the test power supply and a second charging speed of the power supply to be tested.

And then, the test system charges the test power supply and the power supply to be tested respectively through the power supply. It should be noted that, before charging, it is necessary to ensure that both the test power supply and the power supply to be tested are in an empty state and the power supply is in a full state, so as to ensure the accuracy of the test process. When the power supply starts to charge the test power supply, the timing device is used for timing. And stopping timing when the test power supply enters a full power state, and recording the time length consumed by charging, wherein the time length is marked as a first time length. And when the power supply starts to charge the power supply to be tested, timing is performed through the timing device. And when the power supply to be tested enters a full power state, stopping timing, recording the time length consumed by charging, and marking the time length as a second time length.

Then, the rated capacity of the test power supply is used for removing the first time period to obtain a first charging speed, namely, the speed of the process of enabling the test power supply to enter a full power state from an empty power state through the power supply. And removing the second time length by using the residual capacity of the power supply to be tested to obtain a second charging speed, namely, the speed of the process of enabling the power supply to be tested to enter the full power state from the empty power state through the power supply.

And respectively charging the test power supply and the power supply to be tested by adopting the same power supply. The purpose of this is to ensure that both power supplies charge under the same charging conditions in order to compare their charging speeds. When the test power supply enters a full power state, recording a first duration of charging consumption, and when the power supply to be tested enters the full power state, recording a second duration of charging consumption. These durations may reflect the charging rates of the two power sources. By comparing the charging speeds of the two power supplies, the aging degree of the power supply to be tested can be directly reflected, because the charging speed of the battery is generally reduced with the increase of the aging degree.

Of course, in order to test accuracy, multiple tests can be performed, and the charging speed of the test power supply and the charging speed of the power supply to be tested are obtained by calculating an average value. Also in the state of charge of the power supply to be tested and the test power supply, and in the state of full power of the power supply. And charging the test power supply and the power supply to be tested respectively through the power supply. And respectively recording the first time spent by the test power supply from the empty power state to the full power state each time, and obtaining a plurality of first time. And simultaneously, respectively recording second time spent by the power supply to be tested in the full power state from the power supply state each time, and obtaining a plurality of second time. Since the rated capacity of the test power supply is unchanged in a short time, a plurality of first charging speeds can be obtained according to the quotient of the rated capacity and each first duration. And finally, averaging the plurality of first charging speeds to obtain a first average charging speed. Also for short periods of time. The remaining capacity of the test power supply is unchanged, so that a plurality of second charging speeds can be obtained according to the quotient of the remaining capacity and each second duration. And finally, averaging the plurality of second charging speeds to obtain a second average charging speed.

By charging for multiple times and calculating the average charging speed, errors can be reduced, the accuracy of data can be improved, and the charging speeds of the test power supply and the power supply to be tested can be reflected more accurately. Meanwhile, through multiple times of charging and average value calculation, operation errors and data measurement errors can be reduced, and the reliability and stability of data are improved.

And S140, determining the charge speed reduction amount of the power supply to be tested based on the first charge speed and the second charge speed.

If only the test power supply and the power supply to be tested are subjected to single charging test, the reduction of the charging speed of the power supply to be tested, namely the reduction of the charging speed after the power supply to be tested is aged, can be obtained according to the difference between the first charging speed of the test power supply and the second charging speed of the power supply to be tested.

If the test power supply and the power supply to be tested are subjected to multiple charging tests, the reduction of the charging speed of the power supply to be tested can be obtained according to the difference value between the first average charging speed of the test power supply and the second average charging speed of the power supply to be tested.

And averaging the plurality of first charging speeds to obtain a first average charging speed. This step is to obtain more stable and reliable data, and by calculating the average value of the plurality of first charging speeds, abnormal fluctuations of individual data can be eliminated, resulting in a more accurate first average charging speed. And averaging the plurality of second charging speeds to obtain a second average charging speed. This step is also to obtain more stable and reliable data, and by calculating the average value of the plurality of second charging speeds, abnormal fluctuations of the individual data can be eliminated, resulting in a more accurate second average charging speed. And averaging the plurality of second charging speeds to obtain a second average charging speed. This step is also to obtain more stable and reliable data, and by calculating the average value of the plurality of second charging speeds, abnormal fluctuations of the individual data can be eliminated, resulting in a more accurate second average charging speed.

And S150, determining the ageing index of the power supply to be tested according to the capacity reduction amount and the charging speed reduction amount.

First, the ratio of the capacity reduction amount to the rated capacity of the test power supply is calculated. This can be achieved by using the following formula: first ratio = capacity reduction/rated capacity of the test power supply. This ratio will reflect the relationship between the capacity loss of the power supply under test and its original rated capacity.

Next, a second ratio is calculated, and a ratio of the charge speed reduction amount to the first charge speed is calculated. This can be achieved by using the following formula: second ratio=charge speed decrease amount/first charge speed. This ratio will reflect the relationship between the slowing of the charge rate of the power supply to be tested and its initial charge rate.

The weight values are then determined, and in order to further distinguish the effects of the different factors, the weight values need to be determined for the first ratio and the second ratio. These weight values are typically determined based on the priority and importance of the power supply test. The first weight value and the second weight value may be between 0 and 1, and the sum should be equal to 1. For example, if capacity reduction is considered more important for aging, a higher weight value may be given to the first ratio and a lower weight value to the second ratio, or the weights may be assigned according to specific needs.

Finally, the aging index of the power supply is calculated according to the first ratio, the first weight value, the second ratio and the second weight value. This can be achieved by using the following formula: aging index= (first ratio x first weight value + second ratio x second weight value)/2. This aging index will reflect the overall aging of the power supply based on the weight you assign to the different factors.

By combining the capacity reduction amount and the charge speed reduction amount, the degree of aging of the power supply to be tested can be estimated more comprehensively. And meanwhile, different weight values are allowed to be set according to actual conditions so as to adapt to different requirements and scenes. For example, if capacity reduction is more of a concern, the first weight value may be set higher. By calculating the first ratio, the second ratio and the weighted average, a quantized evaluation result can be obtained, and the aging degree of the power supply to be tested can be reflected more intuitively.

It can be seen from the calculation process of the whole aging index that the aging index is obtained to be greater when the remaining capacity of the power supply to be tested is smaller, that is, the battery aging causes lower capacity of the battery, and the decrease of the remaining capacity is greater. Also, when the charging speed of the power supply to be tested is smaller, the charging speed reduction amount is larger, and the corresponding aging index is larger. And the larger the ageing index, the more serious the ageing degree of the power supply to be tested is reflected. The user can be prompted to replace the power supply to be tested for use by setting a threshold value when the calculated aging index is greater than or equal to the threshold value.
