When the electronic equipment needs to be maintained, a maintainer or a service staff can quickly know the service condition of the battery through the recorded charge and discharge times, so that the electronic equipment or the battery can be maintained conveniently.

In practical applications of electronic devices, when the electronic device is repaired or when the battery of the electronic device is replaced and tested, the BTB (connection button between the battery and the electronic device) is pulled out, and the interface end of the battery is disconnected.

Detailed Description

The terms first, second, third and the like in the description and in the claims and drawings are used for distinguishing between different objects and not for limiting the specified sequence.

In the embodiments of the present application, words such as "exemplary" or "such as" are used to mean serving as examples, illustrations, or descriptions. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

At present, after the battery is charged and discharged once, the electronic device can record the charge and discharge times of the battery in a register of the electronic device. When the electronic equipment needs to be maintained, a maintainer or a service staff can quickly know the service condition of the battery through the recorded charge and discharge times, so that the electronic equipment or the battery can be maintained conveniently.

Based on the problems in the technical scheme, the application provides a method for recording the charge and discharge times, which uses a nonvolatile memory to store the old charge and discharge times of the battery before the interface end of the battery is disconnected, and can also store the new charge and discharge times which are recorded again after the interface end is disconnected, so that maintenance personnel or service personnel can obtain the real charge and discharge times of the battery through the nonvolatile memory, and the battery safety protection and health monitoring are facilitated.

Illustrating the implementation of the present application: the charging and discharging times directly recorded by the preset electronic equipment in a conventional mode are real-time charging and discharging times, namely the charging and discharging times recorded in the register are real-time charging and discharging times. The charge and discharge times stored in the first field of the first storage area of the nonvolatile memory are first charge and discharge times, and the charge and discharge times stored in the second field of the first storage area are second charge and discharge times.

After the battery finishes one-time charge and discharge, the electronic equipment records the real-time charge and discharge times and records the real-time charge and discharge times in a first field of a first storage area of the nonvolatile memory. That is, if the interface end of the battery is not disconnected (the battery is not pulled out), the real-time charge and discharge times recorded by the electronic device are the same as the first charge and discharge times.

When the interface end of the battery is disconnected (the battery is pulled out), the real-time charge and discharge times are cleared, but the first charge and discharge times stored in the nonvolatile memory are not cleared, and the first charge and discharge times in the first field are stored in the second field. That is, the second field stores the old charge and discharge times of the battery when the interface terminal is disconnected.

And when the battery is charged and discharged again, the electronic equipment records the real-time charging and discharging times again, and records the re-recorded real-time charging and discharging times in a first field of the first storage area. That is, the first field stores the new charge and discharge times recorded again after the interface terminal is disconnected. Therefore, even if the electronic equipment has a battery pulling scene in the actual use process, a maintainer or service personnel can acquire the real charge and discharge times (namely the real charge and discharge times) of the battery through the first charge and discharge times and/or the second charge and discharge times of the nonvolatile memory.

The charge and discharge times recording method can be applied to electronic devices such as mobile phones, tablet computers, desktop computers, laptops, notebook computers, ultra-mobile personal computers (UMPC), handheld computers, netbooks, personal digital assistants (Personal Digital Assistant, PDA), wearable electronic devices, intelligent watches and the like.

ISP can also optimize the noise, brightness and skin color of the image. The ISP can also optimize parameters such as exposure, color temperature and the like of a shooting scene. In some embodiments, the ISP may be provided in the camera 193.

The camera 193 is used to capture still images or video. The object generates an optical image through the lens and projects the optical image onto the photosensitive element. The photosensitive element may be a charge coupled device (charge coupled device, CCD) or a Complementary Metal Oxide Semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, which is then transferred to the ISP to be converted into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV, or the like format. In some embodiments, electronic device 100 may include 1 or N cameras 193, N being a positive integer greater than 1.

In some embodiments of the present application, the kernel layer further includes a charge and discharge number recording process driver, and when the charge and discharge number recording process is driven, the real-time charge and discharge number of the battery and the identification information of the battery, such as sn, are obtained by calling hal. In the running process of the charge and discharge frequency recording process, whether the real-time charge and discharge frequency is zero is identified, if the real-time charge and discharge frequency is not zero, the real-time charge and discharge frequency is updated to a first field of a first storage area of the nonvolatile memory through hal, and if the real-time charge and discharge frequency is zero, the first charge and discharge frequency in the first field is stored to a second field of the first storage area through hal. Wherein hal is a hardware abstraction layer, which is an interface layer between the operating system kernel and the hardware circuitry.

In some embodiments of the present application, when an application layer or an application framework layer requests a request for obtaining usage information of a power generation pool, for example, a request for inquiring the number of charging and discharging times, the kernel invokes the first number of charging and discharging times in a first field of the nonvolatile memory and/or the second number of charging and discharging times in a second field through hal, and uploads the actual number of charging and discharging times to the application layer after obtaining the actual number of charging and discharging times of the battery based on the first number of charging and discharging times and/or the second number of charging and discharging times, where the application layer outputs usage information of the battery according to the actual number of charging and discharging times.

For easy understanding, the following embodiments of the present application will take the electronic device 200 having the structure shown in fig. 1 and fig. 2 as an example, and the method for recording the number of charge and discharge provided in the embodiments of the present application will be specifically described with reference to the drawings and application scenarios.

Fig. 3 is a flowchart of a method for recording the number of charge and discharge according to an embodiment of the present application, and fig. 4 is a block interaction diagram of the method for recording the number of charge and discharge according to an embodiment of the present application.

As shown in fig. 3, the above method for recording the number of charge and discharge times is applied to an electronic device, and may include:

step S301: acquiring the real-time charge and discharge times of the battery recorded by the electronic equipment;

the electronic device includes a battery that is a rechargeable battery, and in a single cell electronic device, the battery includes a first battery; in the multi-battery device, the battery at least comprises a first battery and a second battery, and correspondingly, a first register of the electronic device records a first real-time charge-discharge frequency, a second real-time charge-discharge frequency and the like of the first battery, and a second register of the electronic device records a third real-time charge-discharge frequency, a fourth real-time charge-discharge frequency and the like of the second battery. A single-cell electronic device will be described below as an example.

When the electronic equipment finishes charging and discharging once, the charging and discharging times of the battery are recorded in a register, and the recorded charging and discharging times of the electronic equipment are the real-time charging and discharging times. After the battery interface end is disconnected (for example, after the connection button of the battery is scratched), the electronic equipment clears the real-time charge and discharge times recorded in the register, that is to say, clears the real-time charge and discharge times. Therefore, the real-time charge and discharge times are the charge and discharge times of the battery recorded before the interface end of the battery is from the connection state to the disconnection state, wherein the connection state of the interface end of the battery refers to the connection of the battery with the control circuit of the electronic equipment, and the disconnection state of the interface end of the battery refers to the disconnection of the battery from the control circuit of the electronic equipment. Optionally, when receiving a connection port disconnection signal, resetting the real-time charge and discharge times recorded by the register.

In the using process of the electronic device, the electric quantity of the battery is detected in real time, whether the electronic device completes one charge and discharge event is determined by monitoring the electric quantity of the battery, specifically, the electronic device monitors the electric quantity to change from the first electric quantity to the second electric quantity and then changes from the second electric quantity to the first electric quantity, and then judges that the battery completes one charge and discharge, for example, the electric quantity is from 0 to 100 and then from 100 to 0, and then completes one charge and discharge. When the battery finishes charging and discharging, the electronic equipment records the times of charging and discharging once in a register and stores the times of charging and discharging in real time. Because the battery interface end of the electronic equipment is disconnected, when the connecting buckle of the battery is scratched, the real-time charge and discharge times can be cleared. After the real-time charge and discharge is cleared, the real charge and discharge times of the battery cannot be obtained. Based on the above, in the usage process of the electronic device, the method for recording the charge and discharge times provided in the embodiment of the present application stores the real charge and discharge times in the nonvolatile memory in synchronization with the real charge and discharge times, so that the real charge and discharge times of the battery are saved.

For example, when the electronic device enters a charging state during use, the recorded real-time charge and discharge times are obtained from the register, and then the real-time charge and discharge times are stored in the nonvolatile memory at the same time. For example, the acquired real-time charge and discharge times are stored in a first field of a first storage area of a nonvolatile memory, the charge and discharge times stored in the first field are defined as first charge and discharge times, the first charge and discharge times are charge and discharge times of a battery associated with the real-time charge and discharge times before the real-time charge and discharge times are not cleared, for example, the first charge and discharge times are real-time charge and discharge times, or the first charge and discharge times are charge and discharge times of the battery after the real-time charge and discharge times are accumulated.

Optionally, when the charging port of the electronic device is plugged into the charger, the electronic device receives a charging signal, and determines that the electronic device is in a charging state. Optionally, the charging signal may be a connection signal of a charging interface of the electronic device, and may also be an input voltage/current signal of the battery. The electronic device may trigger and acquire the real-time charge and discharge times at other occasions besides the real-time charge and discharge times when entering the charge state. For example, the electronic device acquires the real-time charge and discharge times according to a preset period (for example, 11 points per night), which is not limited in any way in the embodiment of the present application.

Or in another possible implementation manner, in a use state of the electronic device, the process of the embodiment of the application may be triggered based on the fact that the battery completes one charge and discharge, for example, the recorded real-time charge and discharge times are obtained from a register, and then the real-time charge and discharge times are stored in the nonvolatile memory at the same time. The manner of storing the number of times of charging and discharging in real time in the nonvolatile memory is the same as that of the above-described embodiment. In this implementation manner, when the battery completes a charge-discharge event, the electronic device records the real-time charge-discharge times in the register, and records the charge-discharge times in the nonvolatile memory at the same time before the real-time charge-discharge times are not cleared. And after the charge and discharge are completed each time, the charge and discharge times are recorded in the nonvolatile memory, so that the real charge and discharge times of the battery are obtained by accumulating the recorded real-time charge and discharge times for a plurality of times.

Or in a possible implementation manner, in a use state of the electronic device, the process of the embodiment of the application may be triggered based on the time clearing of the real-time charge and discharge times, for example, the recorded real-time charge and discharge times are obtained from a register, and then the real-time charge and discharge times are stored in the nonvolatile memory at the same time. The manner of storing the number of times of charging and discharging in real time in the nonvolatile memory is the same as that of the above-described embodiment.

Step S302: judging whether the real-time charge and discharge times are zero or not;

when the real-time charge and discharge times are non-zero, step S303 is executed: updating the first charge and discharge times in a first field of a first storage area of a preset nonvolatile memory according to the real-time charge and discharge times;

when the number of times of real-time charging and discharging is zero, step S304 is executed: updating the second charge-discharge times in the second field of the first storage area according to the first charge-discharge times;

when the battery interface end of the electronic equipment is disconnected (the battery is pulled out), the real-time charge and discharge times recorded in the register by the electronic equipment can be cleared. Therefore, in the process of recording the charge and discharge times, after the trigger obtains the real-time charge and discharge times, whether the connecting buckle of the battery of the electronic equipment is scratched or not is determined by judging whether the real-time charge and discharge times are zero. For example, if the real-time charge and discharge times is not zero, it is indicated that the connection buckle of the battery is not scratched, and at this time, the real-time charge and discharge times in the register can be synchronously stored in the nonvolatile memory, so as to record the charge and discharge times of the electronic device after the current charge and discharge are completed. If the real-time charge and discharge times are zero, the connection buckle of the battery is not scratched in the current charge and discharge period, and at the moment, the first charge and discharge times synchronized with the real-time charge and discharge times in the storage of the nonvolatile memory can be stored as second charge and discharge times, so that the first charge and discharge times stored before the real-time charge and discharge are prevented from being updated simultaneously when the real-time charge and discharge times are re-recorded, and the first charge and discharge times stored before the real-time charge and discharge are cleared are prevented from being covered or lost.

Specifically, the first storage area of the nonvolatile memory is preset to include a first field and a second field, the first field is used for storing the charge and discharge times updated according to the real-time charge and discharge times update, and the second field is used for storing the charge and discharge times recorded before the connecting buckle of the battery is scratched. The charge and discharge times stored in the first field are first charge and discharge times, that is to say, the first charge and discharge times are newly updated charge and discharge times of the battery; the number of charge and discharge times stored in the second field is a second number of charge and discharge times, that is, the second number of charge and discharge times is the number of charge and discharge times recorded before the connecting buckle of the battery is scratched.

After the real-time charge and discharge times are obtained, judging whether the real-time charge and discharge times are zero, if not, updating the first charge and discharge times in a first field of a first storage area of a preset nonvolatile memory according to the real-time charge and discharge times to store the charge and discharge times of the battery in the nonvolatile memory, so that even if the real-time charge and discharge times are cleared by being scratched based on the connection buckles of the battery, the real charge and discharge times of the battery can be obtained through the nonvolatile memory.

When the interface end is disconnected due to the fact that the battery is scratched, the real-time charging and discharging times are cleared, although the first charging and discharging times in the first field cannot be cleared, maintenance personnel or service personnel can obtain the real charging and discharging times of the battery from the first field of the first storage area of the nonvolatile memory. However, when the battery continues to be used, the electronic device needs to update the re-recorded real-time charge and discharge times in the first field at the same time, so that the first charge and discharge times recorded before the battery is pulled out are stored in the second field, and the first charge and discharge times stored before the connecting buckle of the battery is scratched out are prevented from being covered or lost when the re-recorded real-time charge and discharge times are updated in the first field at the same time. Therefore, if the real-time charge and discharge times is zero, the second charge and discharge times in the second field of the first storage area are updated according to the first charge and discharge times.

The following list two implementation manners illustrate the process of recording the number of charge and discharge in the embodiment of the present application:

in one possible implementation manner, after the real-time charge and discharge times recorded by the electronic device are obtained, whether the real-time charge and discharge times are zero is judged, and if the real-time charge and discharge times are not zero, that is, the connecting buckle of the battery is not scratched, the real-time charge and discharge times are copied into the first field of the first storage area. In this implementation manner, the first charge-discharge frequency in the first field is the same as the real-time charge-discharge frequency. For example, when the real-time charge and discharge times is 2, 2 is copied to the first field, so that the first charge and discharge times stored in the first field are 2.

In this implementation manner, the first field of the first storage area synchronously updates the real-time charge and discharge times. If the connection buckle of the battery is scratched to zero the real-time charge and discharge times, the battery is continuously used, the real-time charge and discharge times are recorded again, the first charge and discharge times in the first field are recorded again, and the first charge and discharge times stored in the first field before the connection buckle of the battery is scratched are deleted. Therefore, when the real-time charge and discharge times are determined to be zero, the first charge and discharge times in the first field are stored in the second field, the first charge and discharge times of the battery recorded before the connecting buckle of the battery is scratched are stored in the second field, and the first charge and discharge times (also the actual charge and discharge times of the battery) of the battery recorded before the battery is scratched cannot be obtained after the first charge and discharge times are updated.

The second field stores the first charge and discharge times of the battery recorded before the battery is scratched, and if the battery is scratched for multiple times, the second charge and discharge times stored for multiple times are accumulated to obtain the real charge and discharge times of the battery. Therefore, in this implementation manner, since the first charge-discharge frequency is the same as the real-time charge-discharge frequency, after the connection button of the battery is scratched, the first field is re-recorded as the new charge-discharge frequency, so that when the first charge-discharge frequency in the first field is stored in the second field each time, the real charge-discharge frequency of the battery is stored in the second field by adding the first charge-discharge frequency to the second charge-discharge frequency. For example, if the current second charge/discharge number is zero and the first charge/discharge number is 2, 2 is accumulated to zero, and the second charge/discharge number stored in the second field is 2. If the current second charge and discharge times is 2 and the first charge and discharge times is 2, adding 2 to 2, and the second charge and discharge times stored in the second field is 4. That is, the second charge-discharge number, or the sum of the second charge-discharge number and the first charge-discharge number, is the actual charge-discharge number of the battery.

When maintenance personnel or service personnel need to check the charge and discharge times of the battery, the system can call the second charge and discharge times stored in the second field, or the first charge and discharge times stored in the first field and the second charge and discharge times stored in the second field, so as to provide the maintenance personnel or service personnel with the actual charge and discharge times of the battery.

In another possible implementation manner, after the real-time charge and discharge times recorded by the electronic device are obtained, whether the real-time charge and discharge times are zero is judged, if the real-time charge and discharge times are not zero, that is, the connecting buckle of the battery is not scratched, the real-time charge and discharge times are the real charge and discharge times of the battery, so that the real-time charge and discharge times are copied into the first field, and the first charge and discharge times of the first field are updated. If the real-time charge and discharge times are zero, that is, the connection button of the battery is scratched, the first charge and discharge times are copied to the second field of the first storage area, and the old charge and discharge times (that is, the first charge and discharge times recorded before the real-time charge and discharge times are cleared) of the battery recorded before the battery is scratched are stored in the second field. When the battery is charged and discharged again, the electronic equipment is triggered again to acquire the real-time charging and discharging times recorded by the electronic equipment, if the acquired charging and discharging times are no longer zero, the connection buckle of the battery is not scratched in the current charging and discharging process, and the first charging and discharging times are updated based on the real-time charging and discharging times and the second charging and discharging times in the second field (namely, the sum of the re-recorded real-time charging and discharging times and the old charging and discharging times recorded before the battery is the real charging and discharging times of the battery). The real-time charge and discharge times and the second charge and discharge times can be accumulated and copied into the first field to update the first charge and discharge times; the second charge and discharge times may be copied to the first field, and then the real-time charge and discharge times may be added to the first charge and discharge times of the first field.

That is, in this implementation, the first field holds the latest actual charge/discharge number of the battery (i.e., the first charge/discharge number is the actual charge/discharge number). The real-time charge and discharge times are the charge and discharge times of the battery recorded by the electronic equipment. If the connecting buckle of the battery is not scratched, the real-time charge and discharge times recorded by the electronic equipment are real charge and discharge times of the battery, and the real-time charge and discharge times are directly copied to the first field. If the connecting buckle of the battery is scratched, the real-time charge and discharge times recorded by the electronic equipment are the charge and discharge times recorded again after the connecting buckle of the battery is scratched. In this scenario, the actual charge and discharge times of the battery are: the second charge and discharge times recorded before the connecting buckle of the battery is scratched and the real-time charge and discharge times recorded again after the connecting buckle of the battery is scratched. The second field stores the old charge-discharge times (i.e., the second charge-discharge times) recorded before the battery is scratched, so that when the first charge-discharge times are updated, updating is performed based on the real-time charge-discharge times and the second charge-discharge times in the second field, so that the first charge-discharge times stored in the first field are the latest real charge-discharge times of the battery.

Illustrating: when the obtained real-time charge and discharge times is 2 and the second charge and discharge times of the second field is 0 (the connecting buckle of the battery is not scratched), the real-time charge and discharge times are copied to the first field, and the first charge and discharge times in the first field are 2. And when the battery is charged again, triggering again to acquire the real-time charge and discharge times recorded by the electronic equipment, and when the real-time charge and discharge times is 0, copying the first charge and discharge times into the second field, wherein the second charge and discharge times in the second field are 2. And when the battery is charged again, triggering again to acquire the real-time charge and discharge times recorded by the electronic equipment, and when the real-time charge and discharge times is 1, accumulating the real-time charge and discharge times and the first charge and discharge times and updating the accumulated real-time charge and discharge times and the first charge and discharge times into a first field, wherein the first charge and discharge times in the first field are 3.

Thus, when the maintenance personnel or the service personnel need to check the charge and discharge times of the battery, the system can adjust the first charge and discharge times stored in the first field so as to provide the maintenance personnel or the service personnel with the actual charge and discharge times of the battery.

It can be understood that the method for implementing the record of the number of charge and discharge in the embodiment of the present application includes, but is not limited to, the above two methods, for example, a plurality of second fields may be further provided to respectively store the number of charge and discharge stored in the first field, and the number of charge and discharge recorded before the connection buckle of the battery is scratched multiple times may be obtained by accumulating the second number of charge and discharge in the plurality of second fields.

Step S305: and when a query request of the battery is received, outputting the actual charge and discharge times of the battery according to the first charge and discharge times and/or the second charge and discharge times.

Optionally, since the nonvolatile memory stores the first charge-discharge frequency and the second charge-discharge frequency, when a serviceman or service personnel detects the service condition of the battery, the first charge-discharge frequency and the second charge-discharge frequency in the nonvolatile memory can be adjusted to obtain the actual charge-discharge frequency of the battery. For example, a serviceman may connect an electricity meter to the electronic device, and read the actual number of charges and discharges in the nonvolatile memory through the electricity meter. Subsequently, the maintenance personnel or service personnel can evaluate or optimize the service life, the health condition and the like of the local battery based on the real charge and discharge times, and the embodiment of the application does not limit the service life, the health condition and the like.

In a possible implementation manner, the fuel gauge is connected with an interface of the nonvolatile memory, when the fuel gauge reads the nonvolatile memory, a query request of the battery, such as a charge and discharge frequency acquisition request, is triggered, the electronic device outputs the real charge and discharge frequency to the fuel gauge, and the fuel gauge displays the real charge and discharge frequency.

In another possible implementation manner, when the maintenance APP or the battery safety APP of the electronic device is triggered, a query request, such as a charge/discharge number acquisition request, of the battery is triggered, the electronic device invokes the real charge/discharge number of the battery to the nonvolatile memory, and the maintenance APP or the battery safety APP analyzes the usage information of the battery according to the real charge/discharge number of the battery and outputs the usage information on a display interface.

As shown in FIG. 4, one of the interactive processes is used to enumerate the method for recording the charge and discharge times of the electronic device in the embodiment of the application.

When the charging module of the electronic equipment is connected with the power supply, the charging management module generates a charging signal to trigger the charging and discharging frequency recording process. And acquiring real-time charge and discharge times recorded by the electronic equipment through a charge management module, judging whether the real-time charge and discharge times are zero, and if the charge and discharge times are not zero, updating the first charge and discharge times of the first field of the first storage area of the nonvolatile memory according to the real-time charge and discharge times. And if the real-time charge and discharge times are zero, updating the second charge and discharge times of the second field of the first storage area according to the first charge and discharge times in the first field, so that the data related to the charge and discharge times of the battery are stored in the nonvolatile memory. When a maintenance worker or service worker triggers a maintenance APP, the maintenance APP sends a charge-discharge acquisition request to the electronic equipment; or a serviceman or service personnel externally connects an electric quantity timer on the electronic equipment and sends a charge and discharge frequency acquisition request. The electronic equipment invokes the first charge and discharge times and/or the second charge and discharge times stored in the nonvolatile memory to output the actual charge and discharge times of the battery according to the first charge and discharge times and/or the second charge and discharge times.

According to the charge and discharge frequency recording method, the use scene of the battery is determined according to the real-time charge and discharge frequency recorded by the electronic equipment, and the charge and discharge frequency of the battery is recorded in different recording modes according to different use scenes. If the interface end of the battery is not disconnected and the real-time charge and discharge times are not clear, the real-time charge and discharge times are simultaneously stored in a first field of a first storage area of the nonvolatile memory so as to store the charge and discharge times after the battery is updated; if the interface end of the battery is disconnected and the real-time charge and discharge times are zero, the first charge and discharge times in the first field are stored in the second field of the first storage area so as to save the charge and discharge times of the battery before the real-time charge and discharge times are zero. The first field of the first storage area is used for storing the old charge and discharge times of the battery when the interface end of the battery is disconnected, and the first field is used for storing the new charge and discharge times which are recorded again after the interface end is disconnected, so that the real charge and discharge times of the battery can be reserved through the data of the first field and the second field. The maintenance personnel or service personnel can obtain the real charge and discharge times of the battery through the nonvolatile memory, and the battery safety protection and health monitoring are facilitated.

In the above embodiment, the disconnection of the interface end of the battery is based on the reason that the battery is scratched, and the scratched battery includes the following scenarios:

first scene:

the connection button of the battery is scratched to disconnect the interface end, but the battery is not replaced. For example, a serviceman or service person disconnects the interface end of the battery, but does not remove the battery.

And after the interface of the battery is disconnected, the real-time charge and discharge times recorded by the electronic equipment are cleared. Whether the battery is replaced or not can be determined by the identification information of the battery currently used by the electronic equipment. The identification information can be sn number on the battery.

Based on the first scenario, another embodiment of the present application provides a method for recording the number of charge and discharge, as shown in fig. 5, where the method includes:

step S501: when a charging signal is received, acquiring real-time charging and discharging times of a battery recorded by the electronic equipment and acquiring target identity information corresponding to an identity port of the battery;

when the battery finishes charging and discharging, the electronic equipment records the times of charging and discharging once and stores the times of charging and discharging in real time. Because the battery interface end of the electronic equipment is disconnected, when the connecting buckle of the battery is scratched, the real-time charge and discharge times can be cleared. When receiving a charging signal of the electronic equipment, the embodiment of the application acquires the real-time charging and discharging times of the battery recorded by the electronic equipment. And acquiring target identity information of the battery passing through battery anti-counterfeiting through inquiring a battjd node of the electronic equipment, such as sn of the battery. It can be understood that when the battery leaves the factory, after anti-counterfeiting authentication, the anti-counterfeiting mark sn number is arranged on the battery, and the sn number can be read through the battid node of the battery.

Step S502: searching whether the preset nonvolatile memory stores the identification information of the battery or not;

and when the charge and discharge times of the battery are stored in the nonvolatile memory, the identity information of the battery is stored. And each identity information is associated with the charge and discharge times. That is, the nonvolatile memory stores the number of times of charge and discharge per battery.

In the embodiment of the application, whether the charge and discharge times of the battery are stored for the first time in the nonvolatile memory is determined in advance through the identity information of the battery, and if not, the specific scene that the connecting buckle of the battery is scratched is identified. If the non-volatile memory does not store the identification information, the non-volatile memory is not stored with any charge and discharge times of the battery before, and the record is the first record. If the non-volatile memory stores the identification information, the specific scene that the connecting buckle of the battery is scratched is determined through the comparison of the identification information if the non-volatile memory does not store the charge and discharge times of the battery for the first time.

If the identification information of the battery is stored, step S503 is executed: acquiring first identity identification information stored in a first storage area of the nonvolatile memory;

Step S504: judging whether the first identity information is the same as the target identity information;

the first storage area of the nonvolatile memory is updated along with the real-time charge and discharge times, and the real-time charge and discharge times are the charge and discharge times of the battery currently used by the electronic equipment, so that the battery corresponding to the charge and discharge times stored in the first storage area is the battery currently used by the electronic equipment. If the battery stored in the first storage area is different from the battery currently used by the electronic equipment, the battery of the electronic equipment is replaced, and if the battery is the same, the battery of the electronic equipment is not replaced. Based on this, the present embodiment recognizes a scenario of whether the battery is replaced in the following manner.

Optionally, the battery identification information corresponding to the number of charging and discharging stored in the first storage area is first identification information, and the first identification information may be the same as the target identification information, if the battery is not replaced. Thus, it can be determined whether the battery is replaced by comparing the first identification information with the target identification information. If the identification information is found in the nonvolatile memory and the first identification information is the same as the target identification information corresponding to the battery currently used by the electronic equipment, the battery is not replaced.

In this embodiment, when it is determined that the battery is not replaced through the first identity information, it is determined whether an interface end of the currently used battery is disconnected, that is, whether a connector of the battery is scratched, and specifically, whether the situation that the connector of the battery is scratched but the battery is not replaced is determined. If the connecting buckle of the battery is scratched, the real-time charge and discharge times recorded by the electronic equipment are zero, and if the connecting buckle of the battery is not scratched, the real-time charge and discharge times recorded by the electronic equipment are not zero.

Therefore, when the first identity information is the same as the target identity information, step S505 is performed: judging whether the real-time charge and discharge times are zero or not;

if yes, that is, the real-time charge/discharge frequency is zero, step S506 is executed: and updating the second charge-discharge times in the second field of the first storage area according to the first charge-discharge times.

The method of updating the second charge/discharge number in the second field of the first storage area according to the first charge/discharge number refers to the embodiment shown in fig. 3.

If not, that is, the real-time charge and discharge times are non-zero, step S507 is executed: and updating the first charge and discharge times in a first field of a first storage area of a preset nonvolatile memory according to the real-time charge and discharge times.

The method of updating the first charge/discharge number in the first field of the first storage area of the preset nonvolatile memory according to the real-time charge/discharge number refers to the embodiment shown in fig. 3.

If the identification information is not stored, step S508 is executed: and storing the target identity information and the real-time charge and discharge times in the nonvolatile memory.

If the non-volatile memory does not store the identification information, the non-volatile memory is indicated that the charge and discharge times of any battery are not stored before, and the current record is the first record of the charge and discharge times. When the nonvolatile memory of the electronic equipment records the charge and discharge times for the first time, the obtained target identity information of the battery and the real-time charge and discharge times are stored in the nonvolatile memory.

Optionally, in an embodiment, the target identity information and the real-time charge-discharge number are stored in a first storage area of the nonvolatile memory, and are stored as the first charge-discharge number, or are stored as the first charge-discharge number and the second charge-discharge number.

In this embodiment, whether the battery is replaced is determined through the identity information, so that the recorded actual charge and discharge times are not corresponding to the battery, and the error in the record of the charge and discharge times of the battery is avoided, so that the analysis of the actual service condition of the battery is affected.

In an implementation manner, after the step of obtaining the target identity information corresponding to the identity port of the battery, the method further includes:

and verifying the target identity information effectively, and executing the step of searching whether the preset nonvolatile memory stores the identity information or not.

That is, before comparing the identity information, the obtained target identity information is subjected to anti-counterfeiting authentication again to determine the validity of the target identity information.

The second scenario:

the battery is scratched and replaced with the battery that was originally used. For example, a service person or service person removes the battery, tests with a new battery, and then replaces the original battery.

And after the interface of the battery is disconnected, the real-time charge and discharge times recorded by the electronic equipment are cleared. Whether the battery is replaced or not can be determined by the identification information of the battery currently used by the electronic equipment. The identification information may be SN identification on the battery, for example.

Based on the second scenario, a method for recording the number of charge and discharge according to still another embodiment of the present application, as shown in fig. 6, includes:

Step S601: when a charging signal is received, acquiring real-time charging and discharging times of a battery recorded by the electronic equipment and acquiring target identity information corresponding to an identity port of the battery;

in the embodiment of the present application, step S601 may be referred to the embodiment shown in fig. 5, and the detailed description of step S501 is omitted here.

Step S602: searching whether the preset nonvolatile memory stores the identification information of the battery or not;

in the embodiment of the present application, step S602 may be referred to the embodiment shown in fig. 5, and the detailed description of step S502 is omitted here.

If the identity information of the battery is stored, step S603 is executed: acquiring first identity identification information stored in a first storage area of the nonvolatile memory;

step S604: judging whether the first identity information is the same as the target identity information;

Optionally, the battery identification information corresponding to the first charge and discharge times stored in the first storage area is first identification information, where the first identification information may be different from the target identification information, such as changing the battery scenario. Thus, it can be determined whether the battery is replaced by comparing the first identification information with the target identification information. If the identification information of the battery is found in the nonvolatile memory and the first identification information in the first storage area is different from the target identification information corresponding to the battery currently used by the electronic equipment, the battery is indicated to be replaced.

In the case where the battery is replaced, the old battery which is used by the electronic device may be replaced on the electronic device, or new electronic which is not used may be replaced on the electronic device. In different scenes, the corresponding recording modes of the charge and discharge times are different. Based on this, the embodiment of the present application determines a specific scenario in which the battery is replaced in the following manner in the case where the replacement of the electron is recognized.

If the first identity information is different from the target identity information, step S605 is executed: acquiring second identity information stored in a second storage area of the nonvolatile memory;

In this embodiment of the present application, a second storage area of the nonvolatile storage is defined, where the second storage area is used to store identification information of an old battery that has been used by the electronic device and historical charge and discharge times of the old battery.

Therefore, if the first identity information is different from the target identity information, it is indicated that the battery currently used by the electronic device is the replaced battery. Whether the replaced battery is a used slave battery or not can be determined by the second identification information stored in the second storage area of the nonvolatile memory.

Step S606: judging whether the second identity information is the same as the target identity information;

if the same, step S607 is executed: and acquiring historical charge and discharge times corresponding to the second identity information, updating the first charge and discharge times and the second charge and discharge times stored in the first storage area by adopting the historical charge and discharge times, and updating the first identity information stored in the first storage area by adopting the second identity information.

If the second identity information is the same as the target identity information, the situation that the replaced battery is the battery used by the electronic equipment, namely the battery is determined to be scratched and replaced with the battery used originally, is indicated.

If the battery of the electronic device is replaced by an old battery which is used once, based on the fact that a certain amount of charge and discharge times exist before the old battery is removed, the old battery is removed to clear the real-time charge and discharge times, if the old battery is reloaded, the register reloads the real-time charge and discharge times recorded from 0, the recorded real-time charge and discharge times are not actually the real charge and discharge times of the battery, and the authenticity of the charge and discharge times is affected. Therefore, the present embodiment stores the number of charge and discharge of the removed battery using the second storage area. When the old battery is reloaded, the historical charge and discharge times and the second identity information stored in the second storage area are updated into the first storage area, so that the charge and discharge times are continuously accumulated on the basis of the historical charge and discharge times in the process of using the battery by the electronic equipment, and the times of the true middle-aged side of the battery are obtained.

Optionally, the historical charge-discharge times are adopted to further increase the first charge-discharge times and/or the second charge-discharge times of the first storage area. That is, the first field and the second field of the first storage area are updated synchronously.

Optionally, in this embodiment of the present application, after the battery is mounted on the electronic device, if the battery completes charging and discharging again, the number of times of charging and discharging of the battery is stored in the first storage area, where the number of times of charging and discharging is a sum of the historical actual number of times of charging and discharging and the newly recorded number of times of charging and discharging, and is a new actual number of times of charging and discharging of the battery. The method for recording the number of charge and discharge of the battery uses the embodiment shown in fig. 3 and 4.

In this embodiment, the second storage area is defined as oldbatey, and is used for storing the identity information of the old battery used by the electronic device and the historical charge and discharge times of the old battery. If the battery is detected to be replaced in the using process of the electronic equipment, the system stores the identity information of the replaced battery and the corresponding actual charge and discharge times in the second storage area so as to store the old battery and the charge and discharge times of the electronic equipment, and the historical charge and discharge times of the old battery cannot be obtained when the old battery is used again. The implementation manner can be as follows: when the electronic equipment detects a disconnection signal of an interface end of the battery, if the interface end is reconnected, acquiring target identity information corresponding to an identity port of the reconnected battery; judging whether the target identity information is consistent with first identity information recorded in a first storage area of the nonvolatile memory; if the first identity information and the first charge and discharge times and/or the second charge and discharge times recorded in the first storage area are inconsistent, the first identity information and the first charge and discharge times and/or the second charge and discharge times recorded in the first storage area are stored in the second storage area of the nonvolatile memory, and the historical charge and discharge times of the battery are obtained, wherein the historical charge and discharge times are the first charge and discharge times or the sum of the first charge and discharge times and/or the second charge and discharge times.

That is, when it is detected that the battery is replaced, the first charge/discharge number and the second charge/discharge number of the replaced battery stored in the nonvolatile memory are stored in the second storage area as the history charge/discharge number of the old battery. When the old battery is replaced again, the historical charge and discharge times of the old battery can be obtained through the second storage area, and then the actual charge and discharge times of the battery can be obtained based on the historical charge and discharge times and the real-time charge and discharge times which are recorded again after the old battery is replaced again.

Optionally, if the electronic device includes a plurality of batteries, the corresponding relationship between the identity information of the batteries and the historical charge and discharge times is used for storing the identity information of the batteries in the second storage area respectively. In this embodiment, the configuration of the storage area of the nonvolatile memory can be reduced, and the recording process of the charge and discharge times can be simplified.

Alternatively, in other embodiments, if the electronic device includes a plurality of batteries, a plurality of second storage areas may be configured to store the historical charge and discharge times of each battery, so as to distinguish the historical charge and discharge times of different batteries.

In order to realize simultaneous recording of the charge and discharge times of the new battery and the relevant battery, the embodiment avoids the charge and discharge times of the new battery from covering the charge and discharge times of the old battery after battery replacement. The first storage area of the nonvolatile memory is defined as storing the identity information and the charge and discharge times of the currently used battery, and the second storage area stores the identity information and the charge and discharge times of all used old batteries. Through the combination of the first storage area and the second storage area, each battery is flexibly switched to conduct charge and discharge recording, and applicability is improved.

Third scenario:

the battery is scratched and the battery is replaced with a new battery. For example, a maintenance person or service person removes the battery, detects that the battery is defective, and replaces the battery with a new one for use.

As shown in fig. 7, another embodiment of the present application provides a method for recording the number of charge and discharge times, including:

step S701: when a charging signal is received, acquiring real-time charging and discharging times of a battery recorded by the electronic equipment and acquiring target identity information corresponding to an identity port of the battery;

in the embodiment of the present application, step S701 can be referred to the embodiment shown in fig. 5, and the detailed description of step S501 is omitted here.

Step S702: searching whether the preset nonvolatile memory stores the identity information or not;

in the embodiment of the present application, step S702 may be referred to in the embodiment shown in fig. 5, and the detailed description of step S502 is omitted here.

If the identity information is stored, step S603 is executed: acquiring first identity identification information stored in a first storage area of the nonvolatile memory;

step S704: judging whether the first identity information is the same as the target identity information;

Optionally, the battery identification information corresponding to the first charge and discharge times stored in the first storage area is first identification information, where the first identification information may be different from the target identification information, such as changing the battery scenario. Thus, it can be determined whether the battery is replaced by comparing the first identification information with the target identification information. If the identification information is found in the nonvolatile memory and the first identification information in the first storage area is different from the target identification information corresponding to the battery currently used by the electronic equipment, the battery is indicated to be replaced.

If the first identity information is different from the target identity information, step S705 is executed: acquiring second identity information stored in a second storage area of the nonvolatile memory;

Step S706: judging whether the second identity information is the same as the target identity information;

if not, step S707 is executed: and storing the target identity information and the real-time charge and discharge times in the nonvolatile memory.

If the second identity information is different from the target identity information, the situation that the replaced battery is a battery which is not used by the electronic equipment, namely the battery is determined to be scratched and replaced with a new battery, is indicated.

If the battery of the electronic equipment is replaced by a new battery, the identity information and the real-time charge and discharge times are stored in the nonvolatile memory in order to record the charge and discharge times of the new battery conveniently in the subsequent use process.

Optionally, in one possible implementation manner, if the identity information stored in the nonvolatile memory is different from the target identity information, the replaced battery is not used on the electronic device, may be completely new, or may be used on another electronic device, and if the battery is completely new, the step S707 may be directly executed. If the battery is used on other electronic equipment, the historical charge and discharge times input port corresponding to the target identity information can be output for a user to input the historical charge and discharge times of the battery. In this implementation, if the replaced old battery is used on another electronic device, but not used on the local electronic device, the historical charge and discharge times of the battery can be obtained through a user input mode.

Optionally, in combination with the scenario in each embodiment, one implementation manner is proposed that the number of times of charging and discharging the battery in each scenario can be recorded:

the method comprises the steps of presetting a storage area of one nonvolatile memory of the electronic equipment, defining a first storage area and a second storage area, defining two storage fields of the first storage area, such as a first field and a second field, wherein data stored in the first storage area are identification information of a currently used battery and charge and discharge times of the battery, the first charge and discharge times stored in the first field are updated based on real-time charge and discharge times of the electronic equipment, and the second charge and discharge times stored in the second field are used for storing actual charge and discharge times of currently used electrons. The data stored in the second storage area are the identification information of all used old batteries and the corresponding historical charge and discharge times.

When the electronic equipment is charged, acquiring target identity information of a battery currently used by the electronic equipment and real-time charge and discharge times recorded by the electronic equipment;

determining whether a storage area in the nonvolatile memory is empty;

if yes, the target identity information and the acquired real-time charge and discharge times are stored in the nonvolatile memory. Taking the first charge of the electronic device as an example, the non-volatile memory does not store the identification information and the charge and discharge times of the battery of the electronic device, so the non-volatile memory stores the identification information and the corresponding charge and discharge times of the battery as 0.

If not, comparing the target identity information with the first identity information stored in the first storage area;

and if the target identity information is matched with the first identity information, indicating that the battery of the electronic equipment is not replaced.

Determining whether the real-time charge and discharge times are zero;

if the real-time charge and discharge times are not zero, the real-time charge and discharge times are updated to a first field of the first storage area, and the actual charge and discharge times of the battery are recorded. Taking the battery as a second charging example, when the battery is charged for the first time, the identity information of the new battery and the corresponding charge and discharge times are stored in a nonvolatile memory to be 0. And after the first charge is completed and the discharge is completed, the real-time charge and discharge times of the electronic equipment are recorded as 1, and when the second charge is completed, the real-time charge and discharge times are obtained as 1 (non-zero), and then the real-time charge and discharge times are updated into a first field of the first storage area, namely, the first charge and discharge times are 1. After the third charge and discharge is completed, the real-time charge and discharge times of the electronic equipment are recorded as 2, and the real-time charge and discharge times are updated into the first field of the first storage area, namely, the first charge and discharge times are 2.

If the real-time charge and discharge times are zero, the interface end of the battery is disconnected, the real-time charge and discharge times are cleared, the first charge and discharge times of the first field of the first storage area are updated into the second field, and after the real-time charge and discharge times are recorded again by the battery, the actual charge and discharge times of the battery are obtained based on the second charge and discharge times and the real-time charge and discharge times stored in the second field. Taking the fourth charging of the battery as an example, after the third charging and discharging of the battery are completed and before the fourth charging, the interface end of the battery is disconnected, the real-time charging and discharging times are 0, at this time, the first charging and discharging times in the first field are updated to the second field, and the second charging and discharging times are 2 (or the corresponding charging and discharging times are 3 when the first charging and discharging times are updated and the count is increased by 1). When the battery is charged for the fifth time, if the real-time charge and discharge times are recorded again as 1, the second charge and discharge times are copied into the first field, the first charge and discharge times are updated as 2 or 3, and thus, the actual charge and discharge times are obtained by accumulation based on the real-time charge and discharge times of 1 and the first charge and discharge times of 2 or 3.

If the target identity information is not matched with the first identity information, indicating that the battery of the electronic equipment is replaced, wherein the real-time charge and discharge times are zero after the battery is replaced;

In this case, the currently used battery may be a new battery (a battery not recorded in the nonvolatile memory) or may be a used old battery. Based on the identification information of all used batteries stored in the second storage area, determining whether the currently used battery is a used old battery or not by searching the identification information in the second storage area;

when the target identity information is matched with the second identity information in the second storage area, the currently used battery is a used old battery, and at the moment, the second identity information in the second storage area and the corresponding historical electricity times are updated into the first storage area, so that after the battery finishes charging and discharging and the charging and discharging times are recorded again, the recorded charging and discharging times and the historical charging and discharging times are accumulated, and the actual charging and discharging times of the battery are obtained.

If the target identity information is not matched with the second identity information in the second storage area, the battery which is currently used is a new battery, and the battery which is not recorded in the nonvolatile memory is indicated. And recording the target identity information and the corresponding real-time charge and discharge times in the first storage area at the moment so as to record the battery in the nonvolatile memory.

Different scenes have different influences on the actual charge and discharge times, and if the same recording mode is adopted, the recording accuracy of the actual charge and discharge times can be influenced. Based on the recording process of the charge and discharge times, different recording modes can be adopted for the actual charge and discharge times of the battery under different scenes, and the accuracy of the actual charge and discharge times recording is improved.

In an implementation manner, when the electronic device includes at least two batteries, target identity information corresponding to the identity ports of the batteries is obtained respectively. And comparing the target identity information of each battery with the identity information stored in the nonvolatile memory, and recording the charge and discharge times corresponding to the target identity information according to different comparison results, so that the battery is not influenced by the service conditions of other batteries.

If the electronic device includes at least two batteries, the charging and discharging times may be acquired separately or simultaneously. In one implementation, when a request for acquiring the charge and discharge times of the battery is received, all the actual charge and discharge times in the nonvolatile memory are output. In an achievable mode, a battery charge and discharge frequency acquisition request is received, and the acquisition request is determined to acquire the identity information of the battery; outputting corresponding actual charge and discharge times according to the identity information; i.e. the actual charge and discharge times of each battery are obtained respectively.
