The method has the advantages that the quick charging mode and the super quick charging mode can be preset in the electronic equipment, and the electronic equipment is charged by adopting the super quick charging mode only when the electric quantity of the battery is low, so that the number of times of charging for a long time with the maximum charging power is reduced, the phenomenon that the battery capacity of the electronic equipment is lowered is also slowed down, and the service life of the battery is prolonged.

Description

Charging method and electronic equipment

Technical Field

The application relates to the technical field of terminals, in particular to a charging method and electronic equipment.

Background

The longer the electronic device is operated, the more power is consumed. When the residual electric quantity of the electronic equipment is small, a user is required to charge in time. If the electronic device is not charged all the time, normal use of the user may be affected. In order to reduce the influence of the overlong charging time of the electronic device on the user, some electronic devices are designed to have a larger charging power, for example, 60W (watts), 100W, etc. In this way, the electronic device can be charged with a larger charging power, thereby reducing the charging time.

However, larger charging power may affect the battery capacity of the electronic device. If the electronic device is charged with a relatively large charging power every time, the battery capacity of the electronic device is rapidly reduced, so that the user always fails to use the electronic device even if the user does not use the electronic device frequently. Therefore, although the present charging method provides a faster charging mode, and ensures the experience of users in terms of fast use of electronic equipment, the charging method accelerates the reduction of the battery capacity, thereby greatly reducing the service life of the battery.

Disclosure of Invention

The embodiment of the application provides a charging method and electronic equipment, wherein a charging mode (such as a super rapid charging mode) with relatively high charging speed is adopted to charge the electronic equipment only when the equipment state of the electronic equipment meets certain conditions, so that the number of times of charging with the maximum charging power is reduced, the speed of reducing the battery capacity of the electronic equipment is also slowed down, and the service life of a battery is prolonged.

In order to achieve the above purpose, the embodiments of the present application adopt the following technical solutions:

in a first aspect, a charging method is provided. The charging method is applied to the electronic equipment, and a first charging mode and a second charging mode are preset in the electronic equipment. The first preset temperature corresponding to the first charging mode is smaller than the second preset temperature corresponding to the second charging mode. The first preset temperature is used for limiting the maintenance time of the maximum charging power corresponding to the first charging mode, and the second preset temperature is used for limiting the maintenance time of the maximum charging power corresponding to the second charging mode. In the charging method, the current battery electric quantity of the electronic equipment is firstly obtained, and then the second charging mode is adopted for charging under the condition that the current battery electric quantity of the electronic equipment is smaller than or equal to the first preset electric quantity.

Therefore, in the charging method, the electronic equipment can be charged in the second charging mode only under the condition that the battery electric quantity is smaller than or equal to the first preset electric quantity, so that the electronic equipment is prevented from being charged in the second charging mode every time, the number of times of charging for a long time with the maximum charging power is reduced, the phenomenon that the battery capacity of the electronic equipment is lowered is also slowed down, and the service life of the battery is prolonged. And the electronic device has lower temperature limit on the second charging mode and higher temperature limit on the first charging mode, so when the second charging mode is adopted for charging, the charging maintenance time of the maximum charging power is longer before the battery temperature reaches the second preset temperature, and the charging maintenance time of the maximum charging power is longer than that when the first charging mode is adopted for charging. And in the condition that the maximum charging power is maintained for a long time, the electronic equipment can be charged rapidly, so that the charging speed of the electronic equipment can be improved, and the charging time is shortened. And better use experience is brought to users.

In an implementation manner of the first aspect, when the second charging mode is adopted for charging, a mode selection interface may be displayed to the user when the current battery power of the electronic device is less than or equal to the first preset power, where the mode selection interface is used to display a prompt message for controlling the electronic device to adopt the second charging mode for charging, and the prompt message is used to prompt the user to adopt the second charging mode for charging. Then, in response to the user selecting the second charging mode, charging is performed in the second charging mode. In this implementation manner, the second charging mode is displayed for the user only when the battery power is less than or equal to the first preset power, so that the user can select the second charging mode only when the battery power is less than or equal to the first preset power. Therefore, the situation that the user selects the second charging mode every time is avoided, and the time of charging for a longer time with the maximum charging power can be reduced, so that the phenomenon that the battery capacity of the electronic equipment is lowered is slowed down, and the service life of the battery is prolonged.

In an implementation manner of the first aspect, a control area corresponding to the prompt information may be further displayed on the mode selection interface, and the prompt information may be used to prompt a user to press the control area for a long time to control the electronic device to charge in the second charging mode. In the foregoing charging method, when the second charging mode is used for charging, the second charging mode may also be used for charging in response to the operation of the user pressing the control area for a long time. In this implementation manner, the control area on the mode selection interface may provide an operation area for the user to select the charging mode, and the mode selection interface is only displayed when the battery power is less than or equal to the first preset power, so that the user can select the second charging mode only when the battery power is less than or equal to the first preset power, and the phenomenon that the battery capacity of the electronic device is reduced when the user selects the second charging mode each time can be avoided.

In an implementation manner of the first aspect, when the charging is performed in the second charging mode, a battery temperature of the electronic device may also be obtained, and when the battery temperature is greater than or equal to a second preset temperature, a maximum charging power currently used for charging is reduced, and the charging is performed by using the reduced charging power. In this implementation, the reduction of the charging power is started when the battery temperature is greater than or equal to the second preset temperature, thereby reducing the battery temperature during the reduction of the charging power. Therefore, the temperature of the battery can be ensured to meet the requirement of a temperature threshold value while the charging duration is prolonged, and the battery can not be in a state of maximum power charging for a long time, so that the reduction speed of the battery capacity is slowed down, and the service life of the battery is prolonged.

In an implementation manner of the first aspect, the charging method may further obtain a preset corresponding relationship corresponding to the second charging mode when a current battery power of the electronic device is less than or equal to a first preset power. The preset corresponding relation corresponding to the second charging mode represents the corresponding relation of the battery electric quantity, the battery temperature and the charging power when the electronic equipment is charged. And then, charging by adopting the second charging mode according to the preset corresponding relation corresponding to the second charging mode. In this implementation manner, since the change of the charging power is closely related to the battery temperature and the battery power, the preset corresponding relationship may reflect the situation that the charging power changes with the battery temperature and the battery power when the electronic device is charged in the second charging mode. Therefore, the battery is charged according to the preset corresponding relation, and the purpose of reducing the charging power when the temperature of the battery reaches the temperature threshold value can be achieved, so that the reduction speed of the battery capacity is slowed down, and the service life of the battery is prolonged.

In an implementation manner of the first aspect, the maximum charging power corresponding to the second charging mode and the maximum charging power corresponding to the first charging mode may be the same, or the maximum charging power corresponding to the second charging mode is greater than the maximum charging power corresponding to the first charging mode. Therefore, the purpose of reducing the temperature limit of the second charging mode can be achieved under the condition that the second preset temperature corresponding to the second charging mode is larger than the first preset temperature corresponding to the first charging mode, so that the charging maintenance time of the maximum charging power corresponding to the second charging mode is prolonged, and the charging speed of the electronic equipment is accelerated.

In an implementation manner of the first aspect, the above charging method may further use the second charging mode to perform charging when the electronic device is connected to a standard charger and a current battery capacity of the electronic device is less than or equal to a first preset electric capacity. The standard charger is used for providing charging power which is matched with the maximum charging power corresponding to the second charging mode. In this implementation, after the electronic device is connected to the standard charger, the standard charger can support high-power charging of the electronic device and provide larger charging power for the electronic device.

In an implementation manner of the first aspect, a third charging mode may be preset in the electronic device, where a maximum charging power corresponding to the third charging mode is smaller than a maximum charging power corresponding to the first charging mode. In this implementation, if the third charging mode is a slow charging mode, the first charging mode may be a fast charging mode and the second charging mode may be a super fast charging mode, which may provide multiple charging modes for the user.

In an implementation manner of the first aspect, the above charging method may further use the first charging mode or the third charging mode to perform charging in response to an instruction operation of a user when a current battery capacity of the electronic device is greater than a first preset electric capacity. In this implementation manner, if the obtained battery power is greater than the first preset power when the electronic device starts to charge, the obtained battery power can be regarded as sufficient power when the electronic device starts to charge, and the electronic device cannot use the second charging mode to charge, so that the number of times of charging with the maximum charging power for a long time can be reduced, the phenomenon that the battery capacity of the electronic device is reduced is slowed down, and the service life of the battery is prolonged.

In an implementation manner of the first aspect, in the charging method of the first aspect, in a process of charging in the second charging mode, when a battery power of the electronic device is greater than or equal to a second preset power, the second charging mode is automatically switched to the first charging mode or the third charging mode, and the first charging mode or the third charging mode is used for charging. In this implementation manner, if the battery temperature is still less than or equal to the second preset temperature after the electronic device is charged for a period of time, but the current electric quantity of the battery is relatively high, the electronic device may actively reduce the charging power, so as to reduce the duration of charging with the maximum charging power and slow down the speed of reducing the battery capacity.

In an implementation manner of the first aspect, in the charging method, during charging in the second charging mode, the second charging mode is switched to the first charging mode or the third charging mode in response to a charging mode switching operation of a user, and charging is performed in the first charging mode or the third charging mode. In this implementation, if the battery temperature is still less than or equal to the second preset temperature after the electronic device is charged for a period of time, but the current electric quantity of the battery is relatively high, in this case, the user may choose to reduce the charging power, so as to reduce the duration of charging with the maximum charging power, and slow down the speed of reducing the battery capacity.

In an implementation manner of the first aspect, the above charging method may further use a third charging mode to perform charging when the electronic device is not connected to a standard charger. At this time, since the charger connected to the electronic device is a general charger, the general charger cannot support high-power charging of the electronic device, and cannot provide large charging power for the electronic device. Therefore, when the electronic device and the common charger are used, the electronic device can only be charged in the third charging mode, so that the electronic device can be charged with lower charging power.

In a second aspect, an electronic device is provided that includes a memory, one or more processors; the memory is coupled with the processor; wherein the memory has stored therein computer program code comprising computer instructions which, when executed by the processor, cause the electronic device to perform the charging method according to any of the implementation forms of the first aspect.

In a third aspect, a computer readable storage medium is provided, comprising computer instructions which, when run on an electronic device, cause the electronic device to perform the charging method according to any one of the implementations of the first aspect.

In a fourth aspect, a computer program product is provided which, when run on a computer, causes the computer to perform the charging method according to any of the implementations of the first aspect.

It will be appreciated that the advantages achieved by the electronic device according to the second aspect, the computer readable storage medium according to the third aspect, and the computer program product according to the fourth aspect provided above may refer to the advantages in the first aspect and any possible design manner thereof, and are not described herein.

With the richness of functions of electronic devices such as mobile phones, users increasingly spend time on the electronic devices, so that the electronic devices work for a longer time. However, the longer the electronic device is operated, the more power consumption will be. When the residual electric quantity of the electronic equipment is small, the user is required to charge in time.

Generally, the smaller the remaining power of the electronic device, the longer the charging time of the electronic device. If the electronic device is not charged, normal use of the user is affected. In order to reduce the influence of the overlong charging time of the electronic device on the user, some electronic devices are designed to have a larger charging power, for example, 60W (watts), 100W, etc. In this way, the electronic device can be charged with a larger charging power, thereby reducing the charging time.

For example, in some current charging methods, a charging mode of an electronic device may be set. The charging modes may include a quick charging mode and a normal charging mode, among others. Under the condition that a user connects the charger with the electronic equipment, a charging mode option and the like can be popped up on an interface of the electronic equipment, and the user can select different charging modes according to own requirements.

The quick charging mode and the common charging mode of the electronic equipment are respectively corresponding to preset corresponding relations, wherein the preset corresponding relations refer to corresponding relations of battery electric quantity, battery temperature and charging power in the charging process of the electronic equipment, the corresponding relations can be represented as a change trend of the charging power under different charging time or satisfy curve rules between the charging power and the charging time, and the corresponding relations can be specifically represented in a charging curve mode. For example, referring to the charge graph shown in fig. 1, the horizontal axis of the coordinates in fig. 1 represents the charge time in minutes (min), and the vertical axis represents the charge power in watts (W). The corresponding fast charging curve in the fast charging mode and the corresponding slow charging curve in the normal charging mode are respectively corresponding to the respective maximum charging power. Since the battery temperature of the electronic device increases as the charging power increases, the maximum charging power in the charging curve is maintained for a period of time only, and is not always maintained, in order to meet the requirement of the battery temperature. In order to meet the requirement of the fast charge, the maximum charge power in the fast charge curve is higher than the maximum charge power in the slow charge curve, and then the end time of the fast charge curve (i.e., the charge end time) is earlier than the end time of the slow charge curve.

When the user needs to fully charge the electronic device, the user can select the quick charging mode, and the electronic device can be charged according to the quick charging curve, so that the charging time is greatly reduced. When the user is not urgent to fully charge the electronic device, the user can select the normal charging mode, and the electronic device is charged according to the slow charging curve, and correspondingly, the charging time is longer.

Since the electronic device provides such a fast charging mode, a user often selects the fast charging mode and rarely selects the normal charging mode in order to use the electronic device as soon as possible during actual charging, regardless of the current remaining power of the electronic device. And charging with a larger charging power often affects the battery capacity of the electronic device. If the user selects the quick charge mode every time, the electronic device is charged with a relatively large charge power every time, so that the battery capacity of the electronic device is rapidly reduced, and the electronic device is always powered down even if the user does not use the electronic device frequently. It can be seen that, although the present charging method provides a fast charging mode, ensuring the experience of the user in terms of fast use of the electronic device, the charging method inevitably accelerates the reduction of the battery capacity, thereby greatly reducing the service life of the battery.

Based on the above, the embodiment of the application provides a charging method, which can be applied to electronic equipment. In the method, the electronic equipment presets a first charging mode and a second charging mode. The first preset temperature corresponding to the first charging mode is smaller than the second preset temperature corresponding to the second charging mode, the first preset temperature is used for limiting the maintenance time of the maximum charging power corresponding to the first charging mode, and the second preset temperature is used for limiting the maintenance time of the maximum charging power corresponding to the second charging mode.

Thereafter, in the case where the device state of the electronic device satisfies a certain condition, the charging may be performed in the second charging mode.

The device state of the electronic device may refer to a current battery power of the electronic device, a number of software running in a background of the electronic device, an environmental temperature where the electronic device is located, and the like. The device state meeting a certain condition may be that the current battery power of the electronic device is smaller than or equal to a first preset power, the number of software running in the background of the electronic device is larger than or equal to a preset number, or the environmental temperature of the electronic device is smaller than or equal to a preset temperature threshold value, etc. And the maximum charging power corresponding to the second charging mode may be greater than the maximum charging power corresponding to the first charging mode, or may be equal to the maximum charging power corresponding to the first charging mode.

In the charging method, the electronic equipment adopts the second charging mode only when the equipment state meets certain conditions, so that the electronic equipment is prevented from being charged in the second charging mode every time, the number of times of charging for a long time with the maximum charging power is reduced, the phenomenon that the battery capacity of the electronic equipment is lowered is also slowed down, and the service life of the battery is prolonged.

In addition, the longer the duration of continuous charging with maximum charging power, the higher the temperature of the electronic device is generally. The first preset temperature is used for limiting the maintenance time of the maximum charging power corresponding to the first charging mode, the second preset temperature is used for limiting the maintenance time of the maximum charging power corresponding to the second charging mode, and the first preset temperature is smaller than the second preset temperature, so that the electronic equipment can be regarded as having lower temperature limitation on the second charging mode and higher temperature limitation on the first charging mode. The electronic device has a lower temperature limit on the second charging mode, so that when the second charging mode is adopted for charging, the maximum charging power is charged and maintained for a longer time before the battery temperature reaches the second preset temperature. And in the condition that the maximum charging power is maintained for a long time, the electronic equipment can be charged rapidly, so that the charging speed of the electronic equipment can be improved, and the charging time is shortened. And better use experience is brought to users.

In other embodiments, the charging management chip driver may also receive a charging curve corresponding to the charging mode selected by the user and send the charging curve to the charging management module, and drive the charging management chip to charge the electronic device according to the charging power on the charging curve.

When the charging method in the embodiment of the present application is implemented based on the electronic device 100 shown in fig. 3, the application framework layer may provide a super-fast charging mode in the electronic device 100. The temperature limit of the electronic device for the super rapid charging mode is lower than that for the rapid charging mode, and the duration of the maximum charging power corresponding to the super rapid charging mode is longer than that of the maximum charging power corresponding to the rapid charging mode. When the current battery level of the electronic device 100 is less than or equal to the preset level, the application framework layer may display a super-fast charge mode for the user. In the case that the user selects the super fast charging mode, the application framework layer may send the mode selection result of the user to the kernel layer, so that the kernel layer charges the electronic device 100 according to the charging power corresponding to the super fast charging mode.

In the process, the core layer can also detect the temperature of the battery, and the current charging power is reduced when the temperature of the battery is greater than or equal to a certain temperature threshold value in the charging process of the electronic equipment. Thereby avoiding the problem of reduced battery capacity caused by charging at a larger charging power for a long time.

The charging method provided in the embodiment of the present application will be described below by taking an example in which the electronic device is a mobile phone. As shown in fig. 4, the method may include the following steps S201 to S203.

S201, presetting a first charging mode and a second charging mode by the mobile phone.

The mobile phone can preset a first charging mode and a second charging mode before delivery or in the upgrading process. The first charging mode may be a charging mode in which the maximum charging power is greater than the first preset power.

In some embodiments, the first preset power may be 60W, 80W, 100W, etc., which is not specifically limited in the embodiments of the present application. When the maximum charging power corresponding to the first charging mode of the mobile phone is larger than the first preset power, the first preset power is larger than the first preset power, so that the maximum charging power corresponding to the first charging mode is larger, and the charging speed is higher when the first charging mode is adopted for charging. Therefore, in the case where the maximum charging power corresponding to the first charging mode is greater than the first preset power, the first charging mode can be regarded as the quick charging mode in the foregoing embodiment. And the first charging mode corresponds to a first preset temperature, and the second charging mode corresponds to a second preset temperature.

The maximum charging power corresponding to the second charging mode and used for charging the mobile phone may be the same as or greater than the maximum charging power corresponding to the first charging mode. And the second preset temperature corresponding to the second charging mode is greater than the first preset temperature corresponding to the first charging mode, so that the temperature limit on the second charging mode is reduced.

By way of example, the first preset temperature may be a temperature value that is greater than or equal to 35 ℃, and less than 40 ℃, such as 35 ℃, 37 ℃, 39 ℃, etc.

By way of example, the second preset temperature may be a temperature value that is greater than or equal to 40 ℃, and less than or equal to 45 ℃, such as 40 ℃, 42 ℃, 45 ℃, etc.

The first preset temperature is used for limiting the maintenance time of the maximum charging power corresponding to the first charging mode, and the second preset temperature is used for limiting the maintenance time of the maximum charging power corresponding to the second charging mode. Because the second preset temperature is higher than the first preset temperature, compared with the first charging mode, the second charging mode improves the temperature threshold, so that the limitation of the battery temperature on the charging power is reduced, the charging duration with the maximum charging power is prolonged when the second charging mode is adopted for charging, and the charging speed of the mobile phone is also increased rapidly. The second charging mode may be the super-fast charging mode in the foregoing embodiment.

Fig. 5 is a schematic diagram illustrating a maximum charging power maintenance time when the mobile phone is charged in the first charging mode and the second charging mode, respectively. As shown in fig. 5, the horizontal axis of the coordinate system in the figure represents the charging period, and the vertical axis represents the charging power. The first charge mode corresponds to charge curve a and the second charge mode corresponds to charge curve b. Wherein the charging curve a is the same as the maximum charging power of the charging curve b. Because the temperature threshold corresponding to the second charging mode is increased, when the second charging mode is adopted, the charging time of the maximum charging power is prolonged to a certain extent, so that the battery temperature reaches the temperature threshold, and the time for maintaining the maximum charging power in the charging curve b is longer than the time for maintaining the maximum charging power in the charging curve a. The longer the maximum charge power is maintained, the faster the cell phone charges.

It should be noted that, some mobile phones do not have a fast charging mode, or only have one charging mode, for example, the above-mentioned normal charging mode or slow charging mode, etc., so long as the maximum charging power corresponding to the current charging mode of the mobile phone is greater than the first preset power, the method in the embodiment of the present application may be adopted, and the mobile phone may preset a new charging mode according to the current charging mode, where the charging mode increases the maintenance time of the maximum charging power and increases the temperature threshold of the battery temperature based on the original charging mode. Thus, the purpose of quick charging of the mobile phone can be realized.

In some embodiments, when the maximum charging power corresponding to the charging mode preset by the mobile phone is less than or equal to the first preset power, it may be regarded that the maximum charging power corresponding to the charging mode is actually smaller, and when the charging mode is used for charging, the charging speed is also slower. Therefore, in the case where the maximum charging power corresponding to such a charging mode is less than or equal to the first preset power, such a charging mode can be regarded as the third charging mode, i.e., the slow charging mode in the foregoing embodiment. And the third charging mode corresponds to a third preset temperature. The third preset temperature is used for limiting the maintenance time of the maximum charging power corresponding to the third charging mode.

By way of example, the third preset temperature may be a temperature value that is greater than or equal to 25 ℃, and less than or equal to 33 ℃, such as 25 ℃, 27 ℃, 31 ℃, 33 ℃, etc.

In some embodiments, the mobile phone may have the first charging mode, the second charging mode, and the third charging mode at the same time. In other embodiments, the mobile phone may also have the first charging mode and the second charging mode.

S202, the mobile phone is connected with a charger, the mobile phone obtains the current battery power, and when the current battery power is smaller than or equal to the first preset power, the mobile phone charges in a second charging mode.

Generally, a user can charge a mobile phone regardless of the current battery level of the mobile phone. The specific charging mode is that a user connects the mobile phone with a charger, the charger is connected into a power grid such as household electricity, and high-voltage alternating current in the power grid is converted into low-voltage direct current through the charger, so that charging electric energy is provided for the mobile phone. The charger can be a wireless charger or a wired charger.

In this embodiment, when the battery power of the mobile phone is less than or equal to the first preset power, the battery power of the mobile phone is considered to be less, and the mobile phone needs to be charged urgently. This can reduce the number and duration of charging using the maximum charging power.

The first preset power may be 10%, 20%, 25% of the current battery limit, and the embodiment of the present application is not specifically limited.

In some embodiments, the manner in which the cell phone is charged in the second charging mode includes automatically charging in the second charging mode, charging in the second charging mode in response to a user operation, and so on.

In a mode that the mobile phone is charged in a second charging mode in response to operation of a user, the mobile phone prompts the user in the second charging mode only when the electric quantity of the battery is smaller than or equal to the first preset electric quantity. That is, the user cannot select the second charging mode when the battery power of the mobile phone is greater than the first preset power. Therefore, the condition that a user selects the second charging mode when the electric quantity is sufficient can be reduced, the number of times of charging with the maximum charging power is reduced, the reduction speed of the battery capacity can be slowed down, and the service life of the battery is prolonged.

There are various ways in which the mobile phone prompts the user for the second charging mode, for example, displaying the first mode selection interface, and displaying prompt information on the mode selection interface for the user to select. The prompt information can comprise a plurality of charging modes including a second charging mode; or displaying a second mode selection interface, displaying prompt information corresponding to the second charging mode and a corresponding control area on the mode selection interface, and the like.

For example, referring to fig. 6, when the battery level of the mobile phone is less than or equal to the first preset level after the mobile phone is charged in succession, the mobile phone may display the first mode selection interface. The first mode selection interface may include a super-fast charge mode in addition to a fast charge mode, a slow charge mode, and the like. The user can select the corresponding charging mode according to the own requirement. If the user wants to use the mobile phone at a fast point, the super fast charge mode may be selected, and if the user does not have the need to use the mobile phone, the user may select the fast charge mode, or select the slow charge mode. It can be seen that the first mode selection page can provide the user with options for multiple charging modes, thereby facilitating the selection of the user.

Or after the first mode selection interface is displayed on the mobile phone, the user does not need to use the mobile phone, and does not need to select any charging mode. In this case, the mobile phone may detect whether the selection operation of the user is received within the first preset duration, and if no selection operation of the user is received within the first preset duration, the mobile phone may perform charging in a default charging mode. The default charging mode may be a fast charging mode or a slow charging mode.

For example, referring to fig. 7, when the battery level of the mobile phone is less than or equal to the first preset level after the mobile phone is charged in succession, the mobile phone may further display a second mode selection interface. The second mode selection interface may display only the prompt information for entering the super fast charge mode, the corresponding control area, and the like. For example, the prompt message may be "long press screen center selectable super fast charge mode" or the like, and the control area may be a circular area 700 shown in fig. 7, and the control area may provide an operation area for the user to select the charge mode. The user can be regarded as selecting the super quick charge mode after pressing the circular area 700 in the center of the screen for a long time according to the prompt message. And the mobile phone can also detect whether the long-press operation of the user is received within the first preset time period, and if any selection operation of the user is not received within the first preset time period, the mobile phone can adopt a default charging mode for charging.

In some embodiments, when the mobile phone starts to charge, if the current battery power is greater than the first preset power, the mobile phone may be regarded as having sufficient power when starting to charge. In this case, the mobile phone is not charged in the second charging mode although the second charging mode is already set. In this case, the user cannot select the second charging mode either. At this time, the mobile phone is charged in a default charging mode. Or, referring to fig. 6, the mobile phone may also display a mode selection interface for the user, where only the fast charging mode and/or the slow charging mode are displayed on the mode selection interface, and then the user selects the fast charging mode or the slow charging mode on the mode selection interface, so as to perform an instruction operation, and the mobile phone responds to the instruction operation of the user and charges in the corresponding charging mode.

Therefore, the mobile phone can be limited in a mode of charging the mobile phone in the second charging mode, the number of times and the duration of charging the mobile phone with the maximum charging power can be reduced, the speed of reducing the battery capacity is slowed down, and the service life of the battery is prolonged.

And S203, when the mobile phone is charged in the second charging mode, acquiring the current battery temperature, and when the current battery temperature is greater than or equal to the second preset temperature, controlling the maximum charging power corresponding to the second charging mode to be reduced, and continuing to charge by using the reduced charging power until the mobile phone is charged.

In this embodiment of the present application, the purpose of the second charging mode is to enable the mobile phone to extend the duration of charging with the maximum charging power, but since charging with the maximum charging power for a long time can enable the battery to continuously raise the temperature, thereby reducing the battery capacity, in this embodiment of the present application, the mobile phone also needs to detect the battery temperature and start to reduce the charging power when the battery temperature is greater than or equal to the second preset temperature, thereby reducing the battery temperature in the process of reducing the charging power. Therefore, the temperature of the battery can be ensured to meet the requirement of a temperature threshold value while the charging duration is prolonged, and the battery can not be in a state of maximum power charging for a long time, so that the reduction speed of the battery capacity is slowed down, and the service life of the battery is prolonged.

For example, referring to the charging curve shown in fig. 5, in the charging curve b corresponding to the second charging mode, the time point when the charging power starts to be reduced is the time point when the mobile phone detects that the battery temperature is greater than or equal to the second preset temperature. Before this point in time, the handset is charged with the maximum charging power, and after this point in time, the handset begins to reduce the charging power. The maximum charge power in the charge curve b is maintained for a relatively long time, and the handset may already be in a higher state of charge, e.g., 80%, 85%, etc., when the charge power starts to decrease. Therefore, even if the charging power is lowered thereafter, the remaining uncharged amount of the cellular phone is filled in a short time. As a whole, the charging duration corresponding to the charging curve b is shorter than the charging duration corresponding to the charging curve a.

In some embodiments, during the charging process in the second charging mode, the mobile phone may also continue to obtain the current battery power, if the battery temperature is still less than or equal to the second preset temperature, but the current battery power of the battery is relatively high, for example, the battery power has reached 80%, 85%, etc., where the charging power may also start to be reduced, so as to reduce the duration of charging with the maximum charging power, and slow down the speed of reducing the battery capacity.

For example, the mobile phone may automatically switch the current second charging mode back to the previous first charging mode when the battery temperature is less than or equal to the second preset temperature and the battery power is greater than or equal to the second preset power. The second preset power may be 80%, 85%, etc. After that, the mobile phone continues to charge from the current battery level by adopting the first charging mode. It should be noted that, when the charging is continued in the first charging mode, the mobile phone may obtain a first charging curve corresponding to the first charging mode, for example, a charging curve a shown in fig. 5. And then, the mobile phone starts to charge from the current charging time point according to the first charging curve. Until the mobile phone is charged.

Or, the mobile phone may display a prompt message for reducing the charging power or switching the charging mode to the user when the battery temperature is less than or equal to the second preset temperature and the battery power is greater than or equal to the second preset power. Thus, the user can select whether to reduce the charging power or switch the charging mode according to his own demand.

Referring to fig. 8, when the battery temperature is less than or equal to the second preset temperature and the battery power is greater than or equal to the second preset power, the mobile phone may display a third mode selection interface. A fast charge mode, a slow charge mode, etc. may be displayed in the third mode selection interface. A prompt message for prompting the user to switch the charging mode, for example, "the current electric quantity is sufficient, you can choose to switch to other charging modes", etc. may also be displayed. If the user wants to continue charging in a faster manner, the user can select the fast charge mode; and if the user wants to charge in a slower manner, the user may select the slow charge mode.

In some embodiments, in the process of charging the mobile phone in the second charging mode, when the user does not need to quickly charge, the user can also select to switch the second charging mode to the first charging mode or the third charging mode at any time, so that the duration of charging the mobile phone with the maximum charging power is shortened, or the mobile phone is charged with smaller charging power. This also slows down the rate of decrease in battery capacity.

In this embodiment of the present application, the premise that the mobile phone can adopt the first charging mode or the second charging mode for charging is that a charger, a charging wire, and the like connected with the mobile phone can support the mobile phone to perform rapid charging. That is, the maximum power provided by the charger is matched with or greater than the maximum charging power corresponding to the first charging mode of the mobile phone, and the charging line connecting the mobile phone and the charger can support the maximum charging power corresponding to the first charging mode. If the charger, the charging wire and the like connected with the mobile phone can support the mobile phone to carry out quick charging, the charger is a standard charger matched with the maximum charging power of the mobile phone, and the charging wire is also a standard charging wire. Therefore, after the mobile phone is connected with the charger, the charger can support high-power charging of the mobile phone and provide larger charging power for the mobile phone, so that the mobile phone can adopt the rapid charging mode or the super rapid charging mode in the embodiment.

In some embodiments, if the charger is not a standard charger that can support fast charging, but is a normal charger; or the charging cord is not a standard charging cord that can support rapid charging, but a general charging cord. Then the common charger or common charging cord cannot support high power charging of the mobile phone, and cannot provide larger charging power for the mobile phone. Therefore, when the mobile phone is connected with the common charger or the common charging wire, the mobile phone can only be charged in the third charging mode, so that the mobile phone can be charged with lower charging power.

In general, the fast charging mode (the first charging mode) and the slow charging mode (the third charging mode) both have corresponding preset corresponding relations, and the preset corresponding relations represent the corresponding relations of the current battery power, the current battery temperature and the current charging power when the electronic device is charged in different charging modes. The correspondence may be represented as a trend of change of the charging power at different charging times or satisfy a curve rule between the charging power and the charging time, and may be specifically represented in a manner of a charging curve. Therefore, under the condition of being in a certain charging mode, the mobile phone can also directly acquire a charging curve corresponding to the certain charging mode, and then charge according to the charging curve. The charging curve represents a correspondence between each charging time point in the charging process and the corresponding charging power (or charging current). The inflection point of the charging curve when the maximum charging power starts to decrease and the charging time point corresponding to the inflection point are determined according to the battery electric quantity and the battery temperature of the mobile phone in the actual charging process.

In this embodiment of the present application, the super-fast charging mode (the second charging mode) also corresponds to a preset correspondence, that is, a corresponding curve charging (the second charging curve).

For example, referring to the charge curve diagram shown in fig. 9, the horizontal axis of the coordinate system represents the charge duration and the vertical axis represents the charge power. The fast charge mode corresponds to charge curve a, the super fast charge mode corresponds to charge curve b, and the slow charge mode corresponds to charge curve c. Because the temperature threshold corresponding to the super-fast charge mode is increased, when the super-fast charge mode is adopted, the charging time of the maximum charging power is prolonged to a certain extent, so that the temperature of the battery reaches the temperature threshold, and the time for maintaining the maximum charging power in the charging curve b is longer than the time for maintaining the maximum charging power in the charging curve a. The longer the maximum charge power is maintained, the faster the cell phone charges. And because the maximum charging power corresponding to the slow charging mode is smaller than the maximum charging power of the fast charging mode and the super fast charging mode, the charging time is longer when the slow charging mode is adopted for charging. Further, the charging duration of the charging curve c corresponding to the slow charging mode is longer than the charging durations of both the charging curves a and b.

The mobile phone may store the first charging curve, the second charging curve, and the third charging curve representing the correspondence together. And after the user selects a certain charging mode, the mobile phone can directly acquire the corresponding relation (charging curve) corresponding to the charging mode, so that the charging power is correspondingly adjusted according to the corresponding relation (charging curve) to charge.

Based on this, in some embodiments, the above-described charging method may also be implemented in the manner shown in fig. 10. Referring to fig. 10, after the user connects the mobile phone to the charger, the mobile phone may be charged in a default charging mode, for example, using a third charging mode. And the mobile phone detects the current battery power, and displays the option of the second charging mode to the user when the battery power is smaller than or equal to the first preset power. After the user selects the second charging mode, the mobile phone responds to the selection operation of the user to acquire a corresponding second charging curve. And then, the mobile phone charges according to the second charging curve. And displaying prompt information currently in the second charging mode on a display interface in the charging process.

When the battery power is greater than the first preset power, the mobile phone can display options of the first charging mode and the third charging mode to the user. And then, the mobile phone responds to the selection operation of selecting a certain charging mode by the user, acquires a corresponding charging curve, and charges according to the corresponding charging curve.

In the charging method shown in fig. 10, since the change of the charging power is closely related to the battery temperature and the battery power, and the second charging curve is a power-time curve correspondingly set according to the power change condition of the second charging mode during charging, the second charging curve may reflect the change condition of the charging power when the mobile phone is charged in the second charging mode, and the inflection point of the maximum charging power may represent the charging time point when the battery temperature is greater than or equal to the second preset temperature. Therefore, the battery is charged according to the second charging curve, and the purpose of reducing the charging power when the temperature of the battery reaches the temperature threshold value can be achieved, so that the reduction speed of the battery capacity is slowed down, and the service life of the battery is prolonged.

In some embodiments, if the user does not select the second charging mode, or the current battery power of the mobile phone is greater than the first preset power, the mobile phone may also obtain a corresponding charging curve according to the default charging mode, and correspondingly adjust the charging power according to the charging curve to perform charging.

The embodiment of the application also provides electronic equipment. Referring to fig. 11, the electronic device may include a charge mode setting module 301 and a charge mode judging module 302.

The charging mode setting module 301 is further configured to display an option of the second charging mode for the user when the current battery power is less than or equal to the first preset power. And transmits the result of the user's selection to the charge mode judgment module 302. For example, the relevant contents of step S202 in the foregoing embodiment are executed.

The charging mode determining module 302 is configured to control the electronic device to perform charging in the second charging mode in response to a selection operation of a user. And in the charging process, when the current battery temperature is greater than or equal to a second preset temperature, controlling the maximum charging power corresponding to the second charging mode to be reduced, and continuing to charge by using the reduced charging power until the charging of the electronic equipment is completed. For example, the relevant contents of step S203 in the foregoing embodiment are executed.

In some embodiments, referring to fig. 12, the electronic device may further include a charging profile management module 303. The charging curve management module 303 is configured to store a first charging curve, a second charging curve, a third charging curve, and the like.

The charging curve management module 303 is further configured to receive a result of selecting the charging mode by the user sent by the charging mode determining module 302, obtain a corresponding charging curve according to the selection result, and charge the electronic device according to the charging curve. For example, when the user selects the second charging mode, the charging curve management module 303 obtains a corresponding second charging curve, and charges the electronic device according to the second charging curve.

In some embodiments, as shown in fig. 13, the charge management module 140 in the electronic device may store a plurality of charging modes, such as a first charging mode, a second charging mode, a third charging mode, and so on. When the electronic device is connected to the charger, the charge management module 140 may provide these charging modes to the user.
