Detailed ways

In order to make those skilled in the art better understand the solutions of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.

At present, when charging an electronic device, there is usually a charging time limit, and the charging limit time is usually fixed. For example, the charging limit time of the electronic device is uniformly set to a fixed H hours. However, with the gradual increase of battery capacity, the battery capacity of some electronic devices has increased to 5000mAh

(Megawatt Hour, mAh), or even 6000mAh, it may be larger in the future. If the charging limit time is set to H hours, then in some scenarios with relatively small charging current (such as USB CDP mode), the large-capacity battery is The battery cannot be fully charged, and for some fast charging scenarios, it is uniformly set to H hours, which also poses a greater risk to the protection of the battery.

After long-term research, the inventor has discovered and proposed the charging method, device, electronic device, and storage medium provided by the embodiments of the present application, which can set different charging limit durations for different charging scenarios, so as to realize the charging limit for each charging scenario. The differentiated control of the duration avoids a one-size-fits-all approach, thereby avoiding the situation that the battery cannot be fully charged in a scenario with a small current, and at the same time reducing the risk of battery damage in a scenario with a large charging current. The specific charging method will be described in detail in the following embodiments.

Please refer to FIG. 1. FIG. 1 shows a schematic flowchart of a charging method provided by an embodiment of the present application. In a specific embodiment, the charging method can be applied to the charging apparatus 700 as shown in FIG. 11 and the electronic equipment ( FIG. 12 ) equipped with the charging apparatus 700 . The process shown in FIG. 1 will be described in detail below, and the charging method shown may specifically include the following steps:

Step S110: When the electronic device is in the charging state, determine the current charging scene.

In some embodiments, the electronic device may include a detection circuit for detecting whether the electronic device is in a charged state. As a way, the detection circuit can identify the level value of the pin in the charging interface that is used to indicate the connection to the charging cable. When the level value is high, it can be considered that the current electronic device is connected to the charging device. At this time, it can be considered that the electronic device is detected to be in a charging state. As another way, the detection circuit can also be used to detect whether the coil of the wireless charging unit generates alternating current of a certain frequency. When the coil generates alternating current, it can also be considered that the electronic device is connected to the charging device. An electronic device is detected to be charging.

In other embodiments, whether the electronic device is in a charging state can also be determined through the BatteryManager of the power manager of the electronic device. For example, the BatteryManager broadcasts the charging details of the battery unit, the charging details may include whether the electronic device is in a charging state, and the charging information can be obtained through an Intent to determine whether the electronic device is in a charging state.

In still other embodiments, the detection of whether the electronic device is in a charging state can also be implemented through an API (application programming interface) provided by the electronic device. For example, in the Android system, the command line mPluggedIn=updateMonitor.isDevicePluggedIn() can be used to detect whether the electronic device is in a charging state.

It can be understood that the above method of detecting whether the electronic device is in a charging state is only an example, and the specific detection method is not limited in the embodiments of the present application.

In this embodiment of the present application, when it is detected that the electronic device is in a charging state, the current charging scene can be determined. The charging scene may be a charging environment with a certain charging speed, that is, different charging scenes have different charging speeds.

Since different charging modes may have different charging currents, the charging speeds of different charging modes may be different. Therefore, in some embodiments, the charging scene may be determined according to the charging mode. Among them, the charging method can be a wired charging method and a wireless charging method. The wired charging method needs to plug the plug of the charging cable with the charging interface on the electronic device to be able to charge the electronic device; the wireless charging method needs to place the electronic device. On the wireless charging device, even close to the transmitter of the wireless charging device, the charging operation of the electronic device can be realized. As an embodiment, whether the electronic device adopts the wired charging mode can be determined by detecting the voltage change on the charging interface of the electronic device, and whether the electronic device adopts the wireless charging mode can also be determined by detecting whether the wireless communication module, such as the Bluetooth module, is turned on. charging method. When the electronic device adopts a wired charging method, it can be determined that the current charging scene is a wired charging scene, and when the electronic device adopts a wireless charging method, it can be determined that the current charging scene is a wireless charging scene.

Since different charging devices may support different charging protocols and may have different charging currents, the charging speeds of different charging devices may also be different. Therefore, in another embodiment, the charging scene may also be based on the charging device that charges the electronic device. type is determined. Among them, the type of the charging device may be an adapter charging type, a USB charging type, a type-c charging type, a wireless charger charging type, and the like. Among them, the adapter can be understood as using the standard power adapter configured by the manufacturer. Since there are also different types of adapters, wireless chargers, etc., the type of charging device may be a specific type of adapter, USB, type-c wireless charger, and other charging types. Therefore, it can be determined whether the current charging scene is an adapter charging scene, a USB charging scene, a type-c charging scene, or a wireless charger charging scene, etc. according to the type of the charging device charging the electronic device.

Since the electronic device may have different power consumption when running different application programs, the charging speed of the electronic device may also be different. Therefore, in other embodiments, the charging scene may also be determined according to the device state of the electronic device. The device state may include a standby state and a non-standby state. Therefore, according to the device state of the electronic device, it can be determined whether the current charging scene is a standby charging scene or a non-standby charging scene. Further, when in the non-standby state, the current charging scene may also be determined according to the type of the specific running application.

It can be understood that the above-mentioned types of charging scenarios and methods for determining the current charging scenarios are only examples, and the specific types of charging scenarios and the methods for determining the current charging scenarios are not limited in the embodiments of the present application.

Step S120: Determine the charging limit duration corresponding to the current charging scenario, wherein the charging limit duration corresponding to different charging scenarios is different.

Because if the charging time limit is set uniformly, the electronic device will be charged in some slow charging scenarios, and the large-capacity battery cannot fully charge the battery, and charging in some fast charging scenarios will increase the damage to the battery. risk. Therefore, in the embodiment of the present application, different charging limit durations may be set for different charging scenarios, so as to ensure that the battery is fully charged and at the same time reduce the risk of battery damage. Specifically, after the current charging scene is determined, the charging limit duration corresponding to the current charging scene may be determined, so as to control the charging process of the electronic device according to the charging limit duration.

In some embodiments, the charging limit duration of each charging scenario may be set in advance, so that each time the electronic device is charged, an appropriate charging limit duration may be selected and controlled according to the current charging scenario. As a method, after setting the charging parameters, the charging duration of each charging scene can be obtained through laboratory tests, and then the charging limit duration can be set according to the charging duration of each charging scene obtained by the test. Wherein, the charging limit duration may be greater than the charging duration obtained by testing. For example, the charging time limit can be 1.5 times the test charging time. It can also be equal to the charging time obtained by the test, which is not limited here.

Step S130 : when the charging duration of the electronic device reaches the charging limit duration, stop charging the electronic device.

In the embodiment of the present application, after recognizing the current charging scene and obtaining the charging limit duration corresponding to the current charging scene, the electronic device may record the charging duration of the electronic device, so as to detect that the charging duration of the electronic device reaches the charging limit duration , you can stop charging the electronic device.

In some embodiments, the charging duration of the electronic device may be obtained through the BatteryManager of the power manager of the electronic device, or the charging duration of the electronic device may be recorded through a timer, which is not limited herein. After the charging duration of the electronic device is acquired, it can be determined whether the charging duration is less than the charging limit duration determined above. When the charging duration is less than the above-determined charging limit duration, the charging state of the electronic device can be maintained, and when the charging duration is not less than the above-determined charging limit duration, charging the electronic device can be stopped.

In some embodiments, when the charging duration of the electronic device reaches the charging limit duration, reminder information may also be generated to remind the user to stop charging the electronic device. Further, after it is detected that the charging time of the electronic device reaches the charging limit, if it is still detected that the electronic device is in a charging state after a preset period of time, the power can be automatically cut off or the charging can be stopped automatically. For example, when the current charging method of the electronic device is the Bluetooth wireless charging method, and the charging time of the electronic device reaches the charging limit, if it is still detected that the electronic device is in the charging state after the preset time period, the Bluetooth wireless communication module can be automatically controlled to turn off , which automatically stops charging the electronic device.

In the charging method provided by the embodiment of the present application, when the electronic device is in the charging state, the current charging scene is determined to determine the charging limit duration corresponding to the current charging scene. When the charging time of the device reaches the charging limit, the charging of the electronic device can be stopped. By setting different charging limit durations for different charging scenarios, the present application can realize differentiated control of the charging limit duration for each charging scenario, so that when the electronic device is in the charging state, it can be charged according to the current specific charging status of the electronic device. In some scenarios, the charging time of electronic devices is reasonably limited, which avoids the situation that some scenarios cannot be fully charged due to short charging time, and also reduces the risk of battery damage in some scenarios due to long charging time.

Please refer to FIG. 2, which shows a schematic flowchart of a charging method provided by another embodiment of the present application. The process shown in FIG. 2 will be described in detail below, and the charging method shown may specifically include the following steps:

Step S210: When the electronic device is in a charging state, determine the current charging scene.

In some embodiments, when the electronic device is in the standby state, the power consumption of the electronic device is very small, and when the electronic device is in the non-standby state, the power consumption of the electronic device is relatively large, so that the electronic device is in the standby state. The charging speed of charging in the state is faster than that of charging in the non-standby state. Therefore, it is necessary to set different charging time limits according to different states of the electronic device. Specifically, please refer to FIG. 3. The above-mentioned determination of the current charging scene may include:

Step S211: Detect a device state of the electronic device, where the device state includes a standby state or a non-standby state.

In some embodiments, the device state of the electronic device may be determined by judging whether an application program is running in the foreground of the electronic device. Specifically, when an application program is running in the foreground of the electronic device, it indicates that the user may be currently using the electronic device. At this time, it can be considered that the electronic device is currently in a non-standby state. When the application program is not running in the foreground of the electronic device, it indicates that the user The electronic device may not be currently in use, and at this time, it may be considered that the electronic device is currently in a standby state.

In other embodiments, the device state of the electronic device may also be determined by judging whether the screen state of the electronic device is the screen-off state. Specifically, when the screen state of the electronic device is a bright screen state, it indicates that the user may be currently using the electronic device, and it can be considered that the electronic device is currently in a non-standby state; when the screen state of the electronic device is a screen-off state, it indicates that the user The electronic device may not be currently in use, and it may be considered that the electronic device is currently in a standby state.

In still other embodiments, since there are some low-power applications running, the power consumption is relatively low. Therefore, when the electronic device only runs low-power applications in the foreground, it can be considered equivalent to detecting When the electronic device is currently in a standby state, and when other applications except low-power applications are running in the foreground of the electronic device, it can be considered that it is detected that the electronic device is currently in a non-standby state.

It can be understood that the foregoing detection methods of the device status are only examples, and the specific device status detection methods are not limited in the embodiments of the present application.

Step S212: Determine the current charging scene according to the device state.

In some embodiments, after the device state of the current electronic device is detected, the current charging scene may be determined according to the device state of the electronic device. As a method, when it is detected that the electronic device is currently in the standby state, it is determined that the current charging scene is the standby charging scene, so that the charging of the electronic device can be controlled according to the charging limit time corresponding to the standby charging scene; When the electronic device is currently in a non-standby state, it is determined that the current charging scene is a standby charging scene, so that the charging of the electronic device can be controlled subsequently according to the charging limit duration corresponding to the non-standby charging scene.

As another way, after it is determined that the current device state of the electronic device is the standby state, the current charging scene may be further determined according to the specific charging environment in the standby state. Specifically, referring to FIG. 4 , step S222 may include:

Step S2121: When the device state is the standby state, determine the type of charging device for charging the electronic device.

Since the power consumption of the battery by the electronic device is relatively low when the electronic device is in a standby state, the current charging speed of the electronic device is mainly related to the charging current. Due to different charging devices, the charging current may be different. When different charging devices charge electronic devices, the time for the battery to be fully charged may also be different. Therefore, it is necessary to determine different charging scenarios according to different charging device types. Different charging scenarios can set different charging time limits to reduce the risk of damage to the battery when the charging speed is relatively fast. Specifically, when the device state is the standby state, the type of the charging device for charging the electronic device may be determined. Among them, the charging device type can be an adapter charging type, a USB charging type, a wireless charger charging type, etc. Since different types of charging devices under the same charging type may also support different charging currents, the charging device types can be different types. Adapter charging types, different types of USB charging types, different types of wireless charger charging types, etc. are not limited here.

In some embodiments, the above-mentioned determination of the type of the charging device for charging the electronic device may be to detect the voltage parameter of the charging interface of the electronic device, so as to determine the type of the charging device for charging the electronic device according to the specified voltage condition satisfied by the voltage parameter, The voltage conditions corresponding to different charging device types are different. Generally, the charging interface of the electronic device may be a Mini USB interface, a Micro USB interface, a Type-C interface, a Lighting interface, etc., but is not limited thereto. It can identify whether to use USB charging or adapter charging by detecting the difference in the voltage of each signal of the charging interface. In some embodiments, whether it is a wireless charger charging type can be determined by detecting whether the wireless communication module is turned on. It can be understood that, the charging current of the charging interface of the electronic device can also be detected to determine the type of charging device for charging the electronic device, which is not limited here.

In some embodiments, when detecting the charging voltage of the charging interface of the electronic device, the detection may be performed at intervals of a preset time period, or the detection may be performed in real time, which is not limited thereto. For example, ADC (Analog-to-Digital Converter, analog-to-digital converter) sampling may be performed, and the charging voltage of the charging interface of the electronic device is sampled once at an interval of 2 ms (milliseconds).

Step S2122: Determine the current charging scene according to the type of the charging device.

In some embodiments, when the charging device type is determined, a charging scene related to the charging device type may be determined as the current charging scene. For example, when it is determined that the charging device type is an adapter charging type, a USB charging type, or a wireless charger charging type, it is determined that the current charging scene is an adapter charging scene, a USB charging scene, or a wireless charger charging scene.

As another way, after it is determined that the current device state of the electronic device is a non-standby state, the current charging scene may be further determined according to a specific charging environment in the non-standby state. Specifically, referring to FIG. 5 , step S212 may further include:

Step S2123: When the device state is a non-standby state, determine the type of application currently running on the electronic device.

Step S2124: Determine the current charging scene according to the application type.

In some embodiments, due to the different consumption of battery power when running different applications, the charging speed is also different, so the current charging speed of the electronic device is related to both the charging current and the running application. Therefore, it is necessary to determine different charging scenarios according to the different types of applications running, so as to set different charging time limits according to the different charging scenarios to achieve precise regulation. Specifically, when the device state is in the non-standby state, the type of the application currently running on the electronic device can be determined, so as to determine the current charging scene according to the type of the application. The application type may be an audio type, a game type, an instant communication type, etc., which is not limited here. The corresponding determined current charging scene may also be an audio charging scene, a game charging scene, an instant messaging charging scene, etc., which is not limited here.

Step S220: Determine the charging limit duration corresponding to the current charging scenario, wherein the charging limit duration corresponding to different charging scenarios is different.

Step S230 : when the charging duration of the electronic device reaches the charging limit duration, stop charging the electronic device.

In this embodiment of the present application, for step S220 and step S230, reference may be made to the contents of the foregoing embodiments, and details are not repeated here.

Referring to FIG. 6 , FIG. 6 shows a schematic flowchart of a charging method provided by another embodiment of the present application. The process shown in FIG. 6 will be described in detail below, and the charging method shown may specifically include the following steps:

Step S310: Determine charging limit durations corresponding to different charging scenarios based on a preset reference charging duration, where the reference charging duration is used to represent the charging duration required when the electronic device is in a standby charging scenario.

In some implementations, a reference charging duration may be used as a standard to specifically measure the charging limit duration corresponding to different charging scenarios. As a method, the charging duration required when the electronic device is in a standby charging scenario may be used as the above-mentioned reference charging duration, so as to determine the charging limitation duration corresponding to different charging scenarios.

In some embodiments, the standby charging duration obtained by testing when the electronic device is in a standby charging scenario may be obtained as a preset reference charging duration. Therefore, the charging duration in the standby charging scenario can be tested to obtain a more realistic reference charging duration based on a large amount of experimental data. It is understandable that due to the relatively low power consumption in the standby charging scenario, the charging speed in the standby charging scenario is relatively fast. Therefore, other charging speeds with relatively slow charging speeds are determined according to the standby charging time in the standby charging scenario. The charging limit time of the scene can at least ensure that the battery can be fully charged. In addition, the corresponding charging limit time can also be determined according to the specific charging speed of other charging scenes, so as to reduce the risk of battery damage in different charging scenes.

In other embodiments, since the power consumption in the standby charging scenario is relatively low, the charging current in this scenario may be similar to the theoretical charging current of the electronic device. Therefore, it may also be based on the rated charging parameters and rated battery capacity of the electronic device. Determine the theoretical charging duration of the electronic device as a preset reference charging duration. Among them, the rated charging parameter and the rated battery capacity can be factory default parameters and can be obtained directly.

In some embodiments, the above-mentioned electronic device is in a standby charging scenario, which may be a standby charging scenario when the electronic device is charging with a standard adapter, or a standby charging scenario where other charging devices are charging, which is not limited here. It can be understood that, according to the standby charging scenario of one of the charging devices, after obtaining the charging limit duration, the standby duration of the other charging devices can be calculated through the relationship between the current and the voltage.

In some embodiments, after obtaining the above reference charging duration, the corresponding charging limit duration may be determined according to the specific charging situation of each charging scenario. Specifically, referring to FIG. 7 , step S310 may include:

Step S311: Determine a reference charging parameter of the electronic device based on a preset reference charging duration.

In some embodiments, the reference charging parameter of the electronic device may be determined according to the above-mentioned preset reference charging duration. The reference charging parameter may be a reference charging current, which may be determined by the battery capacity C of the electronic device and the reference charging duration A in the standby charging scenario. For example, by obtaining the ratio C/A of the battery capacity C and the reference charging duration A, the reference charging current B, that is, the average value of the standby charging current in the standby charging scenario, can be obtained.

Step S312: Detect actual charging parameters of the electronic device under different charging scenarios.

Due to the influence of the operating power consumption of the charging device and the electronic device, the actual charging parameters of the electronic device in different charging scenarios are also different. Therefore, the actual charging parameters of the electronic device in different charging scenarios can be detected. The difference between the parameters and the above reference charging parameters is used to determine the charging limit duration in different charging scenarios. Wherein, the actual charging parameter may be an actual charging current.

In some embodiments, when the electronic device is in a standby state, the running power consumption of the electronic device is relatively small, and the actual charging parameter of the electronic device at this time may be determined according to the current charging device type. As a method, when the electronic device is in the standby adapter charging scene, the actual charging parameters of the charging scene can be collected in real time by testing the standby adapter charging scene. It can be understood that, when the above-mentioned reference charging duration is obtained by testing in a charging scenario of a standby adapter, the above-mentioned reference charging parameters can be directly used as actual charging parameters. Therefore, the reference charging duration in the standby adapter charging scenario can be directly used as the charging limit duration in the standby adapter charging scenario.

As another way, when the electronic device is in the standby USB charging scene, the actual charging parameters of the charging scene can be collected in real time by testing the standby USB charging scene. Since the USB charging scene includes the CDP charging mode scene and the SDP charging mode scene, and the charging current of the CDP charging mode scene and the SDP charging mode scene are different, the charging current of the specific charging mode scene can be tested to determine the charging of the specific charging mode scene. Time limit. For example, if the average value E of the charging current in the test SDP charging mode scenario is: 500mA≥E≥300mA, the minimum value of 300mA can be taken as the actual charging parameter of the SDP charging mode scenario.

In some embodiments, when the electronic device is in a non-standby state, the operating power consumption of the electronic device is relatively large, and the actual charging parameter of the electronic device at this time may be determined according to the current operating power consumption of the electronic device. Specifically, referring to FIG. 8 , step S312 may include:

Step S3121: When the electronic device is in the non-standby charging scene, detect the current usage power consumption of the electronic device.

Step S3122: Determine actual charging parameters of the electronic device in the non-standby charging scenario according to the power consumption.

Since the electronic device is in a non-standby charging scenario, the electronic device will cause a relatively large consumption of battery power, so that the charging speed in this charging scenario will definitely be lower than the charging speed in the standby charging scenario. Therefore, when the electronic device is in the non-standby charging scenario, the current usage power consumption of the electronic device can be detected, so as to determine the actual charging parameters of the electronic device in the non-standby charging scenario according to the usage power consumption, so as to be offset The current parameter that is actually charged into the battery after the battery is depleted.

In some embodiments, when the current charging scene is determined according to the type of application currently running on the electronic device, the power consumption of the electronic device when running different applications can also be obtained, so as to determine the charging of various application types. Actual charging parameters in the scene.

In some application scenarios, the charging current of the electronic device may be appropriately adjusted according to the different running applications. For example, when running high-power applications (such as game applications, etc.), the charging current will be increased to avoid affecting the use of electronic devices, while when running low-power applications, the normal charging current can be used for charging. Charge. Therefore, as a method, you can first test the charging parameters of the electronic device under various application types of charging scenarios, and then obtain the power consumption generated by the electronic device when running various applications, and subtract the charging parameters from the charging parameters. The actual charging parameters that the electronic device can actually charge into the battery under various application types of charging scenarios can be obtained by using the power consumption.

For example, when the electronic device currently runs a video application, the current charging scene is a video charging scene, and the average charging current M in the video charging scene can be obtained by testing. Among them, M can be set by charging parameters, and can be tested and collected by multiple electronic devices. Then, the software can directly capture the current use power consumption G of the electronic device in the video charging scene, so that the difference M-G between the average charging current M and the use power consumption G in the video charging scene can be obtained as the electronic device. Actual charging parameters in this video charging scenario.

As another way, the actual charging parameters of the electronic device in the non-standby charging scenario can also be obtained by acquiring the charging parameters of the electronic device in the standby charging scenario, and subtracting the non-standby charging from the charging parameters in the standby charging scenario The usage power consumption in the scenario is determined. Wherein, the charging parameter of the electronic device in the standby charging scenario may be the above-mentioned reference charging parameter of the electronic device determined according to the preset reference charging duration (for example, uploading the reference charging current B); it may also be the rated charging parameter of the electronic device; It may also be the charging current set by the charging protocol in the currently used charger, which is not limited here.

Step S313: Determine the charging limit duration corresponding to different charging scenarios according to the reference charging duration, the reference charging parameters, and the actual charging parameters in the different charging scenarios.

In some embodiments, after the actual charging parameters in different charging scenarios are acquired, the charging limit duration corresponding to different charging scenarios may be determined according to the difference between the reference charging parameters and the actual charging parameters. Specifically, the ratio of the reference charging parameter to the actual charging parameter of different charging scenarios can be obtained first, and then the product of the ratio and the reference charging duration can be obtained, and the product can be used as the charging limit duration of the corresponding charging scenario.

For example, when the actual charging parameter in the standby USB charging scenario is the average charging current E: 300mA, you can first obtain (refer to the charging parameter) the ratio B/E of the reference charging current B to the actual charging parameter E, and then obtain the ratio B The product of /E and the reference charging duration A is F=A*B/E=C/300, and the product F can be used as the charging limit duration in the standby USB charging scenario.

For another example, when the actual charging parameter in the video charging scenario is M-G, the ratio B/(M-G) of the reference charging current B to the actual charging parameter M-G can be obtained (reference charging parameter) first, and then the ratio B/E and the reference charging parameter M-G can be obtained. The product I of the charging duration A=A*B/(M-G)=C/(M-G), and the product I can be used as the charging limit duration in the video charging scenario.

In some scenarios, when the reference charging time is short, if the charging limit time is determined according to the reference charging time, the obtained charging limit time will be relatively short, so that the charging of the electronic device may be stopped earlier. In the case of using an electronic device while charging, the process of charging, stopping charging, then charging again, and stopping charging may be performed frequently, which affects the user's performance. Therefore, in some embodiments, the reference charging duration may also be appropriately extended to determine the charging limitation duration according to the extended reference charging duration. Specifically, referring to FIG. 9 , step S310 may further include:

Step S314: Determine a delay parameter according to the battery performance parameter of the electronic device.

In some embodiments, a delay parameter for delaying the reference charging duration may be determined according to a battery performance parameter of the electronic device. The delay parameter may be a specific time value of the delay, or may be a time multiple of the delay, which is not limited here, and can be set reasonably according to the specific scene.

In some embodiments, the battery performance parameter may be a parameter for evaluating the charging speed of the battery when the electronic device is in a relatively good charging environment, which may be the rated capacity of the battery, or when the electronic device is in a relatively good charging environment, How long to charge the battery to full capacity. There is no limitation here. As a method, when the battery performance parameter is the rated capacity of the battery, if the rated capacity of the battery is less than the preset capacity, it can indicate that the battery will be fully charged in a relatively short period of time. In order to reduce the frequency of charging, the delay parameter can be determined, The above-obtained reference charging duration is extended according to the delay parameter. As another method, when the battery performance parameter is the charging time for the battery to be fully charged, if the charging time is less than the preset time, it means that the battery will be fully charged in a relatively short period of time. In order to reduce the charging frequency, also A delay parameter may be determined to extend the obtained reference charging duration according to the delay parameter. For example, if the charging time when the battery capacity is fully charged is 0.5 hours, the delay parameter can be determined to be the time multiple n of the delay. Wherein, n can take 1.5 or 2, which is not limited here.

Step S315: Extend the preset reference charging duration based on the delay parameter.

In some embodiments, after the delay parameter is determined, the preset reference charging duration may be extended based on the delay parameter. For example, when the delay parameter is the time multiple n of the delay, the extended reference charging duration may be nA, that is, n times the reference charging duration.

Step S316: Determine the charging limit duration corresponding to different charging scenarios according to the extended reference charging duration.

In some embodiments, after obtaining the above-mentioned extended reference charging duration, the charging limit duration corresponding to different charging scenarios may be determined according to the extended reference charging duration.

As a method, when the above-mentioned reference charging duration is obtained by testing in the standby adapter charging scenario, the reference charging duration A can be extended based on the delay parameter, and the extended reference charging duration A can be used as the standby adapter charging duration in the charging scenario. the charging time limit. For example, when the delay parameter is the delay time multiple n, the extended reference charging duration may be nA, that is, the charging limit duration in the standby adapter charging scenario may be D=nA. In some embodiments, when the reference charging duration is relatively short, the extended reference charging duration may be appropriately greater than nA, so that the charging limitation duration in the standby adapter charging scenario may be D≥nA.

In some embodiments, the above-mentioned determination of the charging limit duration corresponding to different charging scenarios according to the reference charging duration, the reference charging parameters, and the actual charging parameters in the different charging scenarios may also be based on an extended reference The charging time duration, the reference charging parameters, and the actual charging parameters in the different charging scenarios determine the charging limit duration corresponding to the different charging scenarios.

For example, when the actual charging parameter in the standby USB charging scenario is the average charging current E: 300mA, you can first obtain (refer to the charging parameter) the ratio B/E of the reference charging current B to the actual charging parameter E, and then obtain the ratio B The product of /E and the extended reference charging duration nA F=nA*B/E=n C/300, the product F can be used as the charging limit duration in the standby USB charging scenario. In some embodiments, when the reference charging duration is relatively short, the extended reference charging duration may be appropriately greater than nA, so that the charging limit duration F≥nA*B/E=n in the standby USB charging scenario C/300.

For another example, when the actual charging parameter in the video charging scenario is M-G, the ratio B/(M-G) of the reference charging current B to the actual charging parameter M-G can be obtained (reference charging parameter) first, and then the ratio B/E and the reference charging parameter M-G can be obtained. The product I=nA*B/(M-G)=nC/(M-G) of the charging duration nA, the product I can be used as the charging limit duration in the video charging scenario. In some embodiments, when the reference charging duration is relatively short, the extended reference charging duration can also be appropriately greater than nA, so that the charging limit duration I≥nA*B/E=nC in the video charging scenario /300.

It can be understood that when the extended reference charging duration is greater than nA, the charging limit duration in the standby adapter charging scenario can be D≥nA. Therefore, it can be deduced that F=D*B/E, I=D*B/( M-G). That is, after obtaining the charging limitation duration D in the standby adapter charging scenario, the charging limitation durations of other charging scenarios can be calculated according to the charging limitation duration D in the standby adapter charging scenario.

Step S320: When the electronic device is in the charging state, determine the current charging scene.

Step S330: Determine the charging limit duration corresponding to the current charging scenario, wherein the charging limit duration corresponding to different charging scenarios is different.

Step S340 : when the charging duration of the electronic device reaches the charging limit duration, stop charging the electronic device.

In this embodiment of the present application, for steps S320 to S340, reference may be made to the contents of the foregoing embodiments, and details are not repeated here.
