The electronic device includes multiple battery levels and multiple load levels, each battery level corresponding to a different battery range. The load level of the electronic device is determined based on the battery temperature and enabled load functions of the electronic device. Based on the correspondence between battery level, load level, and charging power, it determines the current charging power corresponding to the current battery level and the current load level, and designates the current charging power as a third charging power. Reverse charging is then performed based on the third charging power.

[0021] In one embodiment, when the load level of the electronic device is a fixed load level, the reverse charging power of the electronic device is positively correlated with the power level; when the power level of the electronic device is a fixed power level, the reverse charging power of the electronic device is negatively correlated with the load level; the reverse charging power corresponding to the lowest load level and the highest power level of the electronic device is less than or equal to a first charging power, and the highest load level and the lowest power level of the electronic device correspond to stopping reverse charging or corresponding to the lowest reverse charging power supported by the electronic device.

The electronic device then performs reverse charging according to the reverse charging power corresponding to the current charging mode. The electronic device has a first charging mode and a second charging mode, and the reverse charging power corresponding to the first charging mode is different from the reverse charging power corresponding to the second charging mode. Through this disclosure, when an electronic device is reverse-charging, different charging modes (i.e., the first charging mode and the second charging mode) can be used to perform reverse charging with different reverse charging powers. This allows the electronic device to change the charging power by switching charging modes during the reverse charging process, ensuring charging efficiency while making the charging process conform to user needs and the device state.

[0041] Figure 13 This is a block diagram illustrating a device for reverse charging according to an exemplary embodiment. Detailed Implementation

[0042] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0043] The reverse charging method provided in this disclosure is applied to scenarios where an electronic device with reverse charging capability is used to reverse charge an electronic device to be charged.

[0044] Currently, the use of electronic devices such as mobile phones, wearable devices, and laptops is growing exponentially, occupying an indispensable position in users' lives, entertainment, and work. Based on the long-term use needs of electronic devices, users require them to have sufficient battery power to maintain standby mode for extended periods. Ensuring sufficient battery power is predicated on the ability to charge electronic devices at any time. However, when users are out and about, if there is no power source nearby and they do not carry a backup power source, they cannot charge their electronic devices in a timely manner, and the battery capacity becomes insufficient.

[0045] Given that users typically carry multiple electronic devices (such as a primary phone and a backup phone), related technologies incorporate reverse charging functionality for these devices. Electronic devices with reverse charging capabilities can power other electronic devices. Based on this reverse charging function, users can use less frequently used devices to reverse charge other electronic devices with longer usage needs, ensuring that the devices with longer usage needs can remain in standby mode for extended periods. In one example, a user can use a backup phone with reverse charging capabilities to charge their primary phone.

[0046] However, considering the normal usage requirements of electronic devices (such as power consumption and temperature rise during use), related technologies employ a relatively conservative reverse charging strategy when using electronic devices for reverse charging. That is, these technologies do not consider the load state of the electronic device itself, using a fixed minimum charging power or other low, constant power for reverse charging to prevent the electronic device, as the power supply, from being used during charging and causing excessive power consumption or temperature. In summary, the conservative charging strategy using low charging power in these technologies results in low charging efficiency, failing to quickly bring the device to the user's required level of power.

[0047] In view of this, this disclosure proposes a reverse charging method, which determines the current charging mode of the electronic device when it is reverse charging. The electronic device then performs reverse charging according to the reverse charging power corresponding to the current charging mode. The electronic device has a first charging mode and a second charging mode, and the reverse charging power corresponding to the first charging mode is different from the reverse charging power corresponding to the second charging mode. Through this disclosure, when the electronic device is reverse charging, different charging modes (i.e., the first charging mode and the second charging mode) can be used to perform reverse charging with different reverse charging powers. This allows the electronic device to change the charging power by switching charging modes during the reverse charging process, ensuring charging efficiency while making the charging process conform to user needs and the device's state.

[0048] Figure 1This is a flowchart illustrating a reverse charging method according to an exemplary embodiment. Figure 1 As shown, the method includes steps S101 to S102.

[0049] In step S101, in response to the electronic device performing reverse charging, the current charging mode is determined.

[0050] In step S102, reverse charging is performed according to the reverse charging power corresponding to the current charging mode. The charging modes of the electronic device include a first charging mode and a second charging mode. The reverse charging power corresponding to the first charging mode is different from the reverse charging power corresponding to the second charging mode.

[0051] In this embodiment of the disclosure, the electronic device has multiple charging modes, including a first charging mode and a second charging mode, and the first charging mode and the second charging mode correspond to different reverse charging powers. By selecting the desired charging mode when the electronic device determines that reverse charging needs to be performed, the charging rate of the electronic device can meet the user's needs, and reverse charging can be performed with the charging power required by the user. By switching the charging mode during the reverse charging process of the electronic device, the charging power of the electronic device can meet the user's dynamic needs and the dynamically changing device state of the electronic device.

[0052] It is understood that the different charging modes in this disclosure can correspond to different reverse charging control logics, rather than simply adjusting the charging level when reverse charging is required. Furthermore, it is understood that, based on the different reverse charging modes of the electronic device, the user can select the desired charging mode when establishing an electrical connection between the electronic device and the device to be charged, ensuring that the electronic device charges at the optimal charging power and guarantees charging efficiency. It is further understood that during the reverse charging process, the electronic device's own state (such as load, remaining power, etc.) will change as charging progresses, and the user's usage of the electronic device (such as not using the electronic device and putting it into standby mode, or opening application functions, etc.) will also change. In this case, a single charging control logic (i.e., using a fixed charging mode) cannot adapt to the dynamically changing usage and state of the electronic device. Through the multiple charging modes (first charging mode) involved in this disclosure, mode switching can be achieved during charging, thereby adapting the reverse charging process to the usage and state of the electronic device, ensuring that the electronic device maintains its normal state while performing reverse charging at the optimal charging rate.

[0053] In the embodiments of this disclosure, the first charging mode and the second charging mode correspond to different charging control logics. The following embodiments of this disclosure describe a method for adjusting the charging power of reverse charging according to the first charging mode.

[0054] Figure 2 This is a flowchart illustrating a method for reverse charging based on the reverse charging power corresponding to the current charging mode, according to an exemplary embodiment. Figure 2 As shown, the method includes steps S201 and S202.

[0055] In step S201, in response to the current charging mode being the first charging mode, the load mode of the electronic device is set to the preset load mode, and the reverse charging power of the electronic device is adjusted to the first charging power.

[0056] The first charging mode is a charging mode that uses the first charging power for reverse charging. The difference between the first charging power and the maximum reverse charging power supported by the electronic device is less than a threshold. The preset load mode is a load mode that disables the preset load function.

[0057] In step S202, reverse charging is performed according to the first charging power.

[0058] In this embodiment, the first charging mode is a high-efficiency reverse charging mode. In the first charging mode, the electronic device charges in reverse with a first charging power wave. The first charging power is close to or equal to the maximum charging power it supports (i.e., the difference between the first charging power and the maximum reverse charging power supported by the electronic device is less than a threshold). When the current charging mode is the first charging mode, the electronic device shuts down preset load functions (such as various third-party applications and system applications, Wi-Fi function, location function, etc.), that is, it shuts down all load functions except for the reverse charging function and basic load functions (such as load functions that keep the device in normal standby and communication functions), enters the preset load mode, and after entering the preset load mode, the charging power of the electronic device is set to the first charging power corresponding to the highest reverse charging power supported by the electronic device, and reverse charging is performed with the first charging power. In summary, in the first charging mode, the electronic device is not considered to be used normally, but only its reverse charging function is used while its basic functions are being performed, that is, the electronic device is used as a "portable power bank".

[0059] In this embodiment of the disclosure, the "preset load functions" that need to be turned off in the first charging mode include various load functions, but do not include basic functions that maintain the normal standby mode of the electronic device. In one example, this disclosure turns off functions such as Wi-Fi, mobile data, location services, and Bluetooth, closes various applications, and enters a screen-off state, thereby enabling the electronic device to enter a low-load mode.

[0060] It is understandable that users, when urgently needing to restore the battery of a device, would have high requirements for the charging power when the electronic device performs reverse charging. The first charging mode in this disclosure allows the electronic device to reverse charge the device at a power close to or equal to its maximum charging power. Furthermore, it is understood that power consumption from screen illumination and application operation affects the charging power during reverse charging. Therefore, when the electronic device performs reverse charging in the first charging mode, unnecessary load functions are disabled to maintain the highest charging power for reverse charging.

[0061] It is understood that users can set the reverse charging mode again based on their own needs while the electronic device is performing reverse charging in a certain reverse charging mode. For example, while the electronic device is performing reverse charging in a second charging mode, the user can set the reverse charging mode back to the first charging mode. The following embodiments further illustrate the reverse charging method of this disclosure.

[0062] In one embodiment of this disclosure, during the process of setting the load mode of an electronic device to a preset load mode, the method further includes: using a second charging power for reverse charging, wherein the second charging power is less than the first charging power.

[0063] Understandably, when an electronic device determines that the current charging mode is the first charging mode, it needs to disable various preset load functions to enter the preset load mode, which requires a certain delay. To improve the overall charging speed of reverse charging and prevent device overheating caused by inconsistency between the charging efficiency and the device state, this disclosure charges the device to be charged at a second charging power close to the lowest supported reverse charging power during the time period between determining that the current charging mode is the first charging mode and entering the zero-load mode.

[0064] It is understood that the first charging mode in this disclosure requires the electronic device to reverse charge at a first charging power close to or equal to the maximum charging power, which places certain requirements on the device state of the electronic device. When the device state of the electronic device changes, it may cause the electronic device to exit the first charging mode. The following embodiments of this disclosure further illustrate the reverse charging method of this disclosure.

[0065] Figure 3 This is a flowchart illustrating a reverse charging method according to an exemplary embodiment. Figure 3 As shown, the method includes steps S301 to S302.

[0066] In step S301, in response to determining that the electronic device exits the first charging mode, the current charging mode of the electronic device is set to the second charging mode, which is a charging mode that uses a third charging power for reverse charging, and the third charging power is less than or equal to the first charging power.

[0067] In step S302, reverse charging is performed according to the third charging power.

[0068] In this embodiment, the first charging mode is a relatively extreme charging mode that requires disabling unnecessary load functions and using a reverse charging power (i.e., the first charging power) close to or equal to the maximum charging rate of the electronic device. Enabling the first charging mode places relatively strict requirements on the load state and remaining battery power of the electronic device. User usage and a decrease in the device's battery power can both cause the device to exit the first charging mode. Therefore, in the event that the electronic device exits the first charging mode, this disclosure activates a second charging mode, using the reverse charging power (the third charging power) corresponding to the second charging mode for reverse charging.

[0069] This disclosure enables mode switching during charging, thereby adapting the reverse charging process to the usage and status of the electronic device, ensuring that the electronic device maintains its normal state while performing reverse charging at the optimal charging rate.

[0070] In this embodiment of the disclosure, when the electronic device is reverse-charged, changes in the load state of the electronic device and a decrease in the remaining power will cause the electronic device to exit the first charging mode. The following embodiments of this disclosure describe the method for determining when the electronic device exits the first charging mode.

[0071] Figure 4 This is a flowchart illustrating a method for determining whether an electronic device should exit a first charging mode, according to an exemplary embodiment. Figure 4 As shown, the method includes steps S401 to S402.

[0072] In step S401, in response to determining that the electronic device exits the preset load mode and / or the current battery level of the electronic device is less than a preset battery level threshold.

[0073] In step S402, it is determined that the electronic device exits the first charging mode.

[0074] In this embodiment of the disclosure, when the electronic device is reverse charging in the first charging mode, it is determined in real time whether to exit the preset load mode and the battery level of the electronic device is determined in real time. When the electronic device exits the preset load mode and / or the current battery level of the electronic device corresponds to the lowest battery level, it indicates that the electronic device cannot perform reverse charging with the highest charging power, and therefore exits the first charging mode.

[0075] Understandably, when users have temporary needs for using electronic devices, they will activate the device's load function. In this case, the electronic device is considered to have exited the preset load mode. After exiting the preset load mode, the electronic device's load level increases, and it can no longer continue to reverse charge at the highest charging power. Therefore, after exiting the preset load mode, the electronic device also simultaneously exits the first charging mode. Furthermore, it can be understood that the charging efficiency of the electronic device during reverse charging is affected by the remaining battery power. When the remaining battery power is below a certain value, the electronic device cannot continue to reverse charge at the highest charging power. Therefore, when the remaining battery power is below a certain value, the electronic device also simultaneously exits the first charging mode. In this situation, the electronic device starts the second charging mode, using the corresponding reverse charging power (third charging power) for reverse charging.

[0076] It is understandable that during reverse charging of an electronic device, if the user has temporary usage needs, the user will activate part of the electronic device's load function, causing the electronic device's load to increase. In this case, the electronic device is considered to have exited the zero-load mode. Furthermore, it is understood that when the electronic device is charging in reverse at its maximum charging power, the battery temperature of the electronic device will gradually rise. Since the battery temperature is also a factor determining the load state of the electronic device, when the battery temperature exceeds a certain value, the electronic device is considered to have exited the zero-load mode. The following embodiments of this disclosure describe a method for determining when an electronic device exits a preset load mode.

[0077] Figure 5 This is a flowchart illustrating a method for determining whether an electronic device should exit a preset load mode, according to an exemplary embodiment. Figure 5 As shown, the method includes steps S501 to S502.

[0078] In step S501, in response to the battery temperature of the electronic device being higher than a temperature threshold and / or the electronic device activating a preset load function.

[0079] In step S502, it is determined that the electronic device exits the preset load mode.

[0080] In this embodiment, during reverse charging of the electronic device in the first charging mode, the battery temperature of the electronic device is monitored in real time, and it is also monitored whether the electronic device enables a new load function. If the battery temperature of the electronic device is lower than or equal to a temperature threshold, and the electronic device does not enable a new load function, it is considered that the electronic device is still maintaining the preset load mode and continues to reverse charge at the highest charging power. If the battery temperature of the electronic device is higher than the temperature threshold and / or the electronic device enables a new load function, it is considered that the electronic device has exited the preset load mode, and then exits the first charging mode and enters the second charging mode. In the second charging mode, the load level and power level of the electronic device are determined in real time, and the charging level is determined according to the load level, power level and preset correspondence of the electronic device, and reverse charging is performed according to the charging efficiency corresponding to the determined charging level.

[0081] It is understandable that during reverse charging of an electronic device, if the user has temporary usage needs, they may activate some of the device's load functions, causing the device's load to increase. In this case, the electronic device is considered to have exited the preset load mode. Furthermore, it is understandable that when an electronic device performs reverse charging at its maximum charging power, the battery temperature gradually rises. Since battery temperature is a factor determining the device's load state, when the battery temperature exceeds a certain value, the electronic device is considered to have exited the preset load mode.

[0082] In this embodiment of the disclosure, in the second charging mode, the load level and power level of the electronic device are parameters that can be determined in real time. By using the real-time determined load level and power level, and a preset correspondence representing the relationship between load level, power level, and charging level, the current charging level can be determined in real time, and reverse charging can be performed according to the charging power corresponding to the current charging level. The following embodiments of this disclosure describe the method of reverse charging according to the second charging mode.

[0083] Figure 6 This is a flowchart illustrating a method for reverse charging based on the reverse charging power corresponding to the current charging mode, according to an exemplary embodiment. Figure 6 As shown, the method includes steps S601, S602 and S603.

[0084] In step S601, in response to the current charging mode being the second charging mode, the current power level corresponding to the current power level of the electronic device is determined, and the current load level of the electronic device is determined.

[0085] The electronic device includes multiple power levels and multiple load levels. The multiple power levels of the electronic device correspond to different power ranges, and the load level of the electronic device is determined based on the battery temperature and the enabled load functions.

[0086] In step S602, based on the correspondence between the power level, load level and charging power, the current charging power corresponding to the current power level and the current load level is determined, and the current charging power is determined as the third charging power.

[0087] In step S603, reverse charging is performed according to the third charging power.

[0088] In this embodiment, when the current charging mode is the second charging mode, reverse charging control logic that dynamically adjusts the charging power according to the device status is used to perform directional charging. That is, the third charging power used in the second charging mode is a dynamically changing charging power. In the second charging mode, the current battery level and current load level of the electronic device are determined in real time. Based on the current load level, current battery level, and a preset correspondence (defining the correspondence between the load level, battery level, and charging level of the electronic device), the current charging level corresponding to the current load level and current battery level is determined, and the charging power corresponding to the current charging level is set as the charging power of the electronic device (i.e., the third charging power). Reverse charging is then performed according to the set charging power.

[0089] It is understandable that there is a time delay between determining the current battery level and load level of the electronic device and setting the charging power according to the determined current load level. This disclosure enables the electronic device to reverse charge at the lowest charging power supported by the electronic device within the aforementioned time delay, avoiding the use of a charging power higher than the charging power corresponding to the current load level and current battery level, thereby preventing the temperature of the electronic device from rising and ensuring the stability of the electronic device during the reverse charging function.

[0090] In an exemplary embodiment of this disclosure, such as Figure 7As shown in the flowchart of the reverse charging method, this disclosure adopts the following approach for reverse charging based on the second charging mode: Upon detecting insertion and confirming the current charging mode is the second charging mode, reverse charging begins. The minimum power is broadcast, meaning reverse charging is performed using the minimum charging power supported by the electronic device. The current battery level and user usage scenario are determined, i.e., the current battery level and current load level are identified. The maximum power at that level is broadcast, i.e., the charging level corresponding to the current battery level and current load level is determined according to a preset relationship, and reverse charging is performed using the charging power corresponding to the determined charging level. Whether other battery levels and user usage scenarios are triggered, i.e., whether the current battery level and current load level have changed. If no change has occurred, the charging power corresponding to the previously determined charging level is maintained. If a change has occurred and another reverse charging level is triggered, the changed charging level power is broadcast, i.e., reverse charging is performed using the charging power corresponding to the changed charging level. If a change has occurred and another uncharged charging level is triggered, reverse charging is stopped.

[0091] In an exemplary embodiment of this disclosure, battery capacity is categorized into high, medium, and low. Usage scenarios (i.e., load levels) are categorized into high-load scenarios (i.e., high load level), medium-load scenarios (i.e., medium load level), and low-load scenarios (i.e., low load level). Reverse charging levels are categorized into 1-5, where level 1 is the highest charging level and level 5 is the lowest charging level. Under the above conditions, the preset correspondence between the load level, capacity level, and charging level of the electronic device is shown in the following table:

[0092]

[0093] In this embodiment of the disclosure, in the second charging mode, the charging efficiency during reverse charging is set according to a preset correspondence, the electronic device's battery level, and the electronic device's load level. The electronic device's battery level reflects its electrical capacity, and the electronic device's load level reflects its load state (or load scenario). In other words, the preset correspondence characterizes the relationship between battery capacity, load state, and charging efficiency during reverse charging. The following embodiments further illustrate the reverse charging method of this disclosure.

[0094] In one embodiment of this disclosure, when the load level of the electronic device is a fixed load level, the reverse charging power of the electronic device is positively correlated with the power level, and when the power level of the electronic device is a fixed power level, the reverse charging power of the electronic device is negatively correlated with the load level; the reverse charging power corresponding to the lowest load level and the highest power level of the electronic device is less than or equal to the first charging power, and the highest load level and the lowest power level of the electronic device correspond to stopping reverse charging or the lowest reverse charging power supported by the electronic device.

[0095] In this embodiment, multiple load levels (such as high load level, medium load level, and low load level) are defined based on the enabled load function and battery temperature of the electronic device. Different load levels correspond to different load functions and battery temperatures. This disclosure also defines power levels (such as high power level, medium power level, and low power level) by setting different power thresholds, each power level corresponding to a different power range (e.g., high power level corresponds to 66%-100% power percentage, medium power level corresponds to 33%-66% power percentage, and low power level corresponds to 0%-33% power percentage). This disclosure provides multiple incremental charging levels, each corresponding to a different charging power. The highest charging level corresponds to a charging power less than or equal to the highest charging power supported by the electronic device, while the lowest charging level corresponds to the lowest charging power supported by the electronic device or corresponds to stopping reverse charging. The preset correspondence in this disclosure is the correspondence between the electronic device's load level, power level, and charging level.

[0096] It is understood that users can set a default reverse charging mode for electronic devices. If the electronic device has a preset default reverse charging mode, then when reverse charging is needed, the default reverse charging mode will be used as the current charging mode and reverse charging will be performed. However, if the electronic device does not have a preset default reverse charging mode, then when reverse charging is needed, the user selects the current charging mode from a first charging mode and a second charging mode, and reverse charging will be performed according to the user-selected current charging mode. The following embodiments of this disclosure describe the method for determining the current charging mode.

[0097] Figure 8 This is a flowchart illustrating a method for reverse charging based on the reverse charging power corresponding to the current charging mode, according to an exemplary embodiment. Figure 8 As shown, the method includes steps S701, S702A, and S702B.

[0098] In step S701, it is determined that the electronic device is performing reverse charging.

[0099] In step S702A, in response to the electronic device having a default reverse charging mode, the default reverse charging mode is determined as the current charging mode.

[0100] In step S702B, in response to the electronic device not having a default reverse charging mode set, a charging mode selection interface is displayed, and function options for the user to select a charging mode are displayed on the charging mode selection interface. Based on the function options selected by the user, the current charging mode is determined.

[0101] This disclosure includes an exemplary embodiment, such as Figure 9AAs shown in the schematic diagram of the charging mode selection interface, the electronic device displays a variety of charging modes that the user can select. These include options such as enabling extreme reverse charging mode (i.e., using the first charging mode as the current charging mode) or enabling dynamic adjustment reverse charging mode (i.e., using the second charging mode as the current charging mode).

[0102] This disclosure includes an exemplary embodiment, such as Figure 9B As shown in the schematic diagram of the charging mode selection interface, the electronic device displays a single option pointing to a specific charging mode (whether to enable extreme reverse charging, corresponding to the first charging mode). If the user selects "OK," the charging mode specified by that single option (such as the first charging mode) is set as the current charging mode. If the user selects a blank area, another charging mode (such as the second charging mode) is entered.

[0103] In this embodiment of the disclosure, the user can preset the default charging mode to be used when performing reverse charging in the interface for setting the reverse charging mode (such as the corresponding interface in the system settings application). For example, if the default reverse charging mode of the electronic device is the first charging mode, then when it is determined to perform reverse charging, the first charging mode is determined as the current charging mode, and the charging power is set according to the first charging mode to perform reverse charging.

[0104] In this embodiment of the disclosure, if the electronic device has not been pre-set with a reverse charging mode, the user needs to further select the desired reverse charging mode. That is, when the electronic device establishes an electrical connection with the device to be charged and determines that reverse charging is required, the electronic device displays function options (including a first charging mode and a second charging mode) for the user to select a charging mode, and determines the current charging mode based on the function option selected by the user, and then performs reverse charging according to the reverse charging mode selected by the user.

[0105] In this embodiment, the user can pre-set the default reverse charging mode during the reverse charging process of the electronic device, or select the desired reverse charging mode on the spot if no default reverse charging mode is set. This diverse reverse charging mode setting allows users to customize the charging mode according to their own needs, ensuring charging efficiency while also meeting personalized requirements.

[0106] It is understood that the electronic device in this disclosure also supports a "normal charging mode" that performs reverse charging at a specific charging power. In an exemplary embodiment of this disclosure, as... Figure 10As shown in the flowchart of the charging method, this disclosure controls the electronic device to perform reverse charging function in the following manner: In response to the start of reverse charging, it is determined whether to enter the extreme reverse charging mode (i.e., whether the default charging mode is the first charging mode). If the extreme reverse charging mode is entered, after detecting insertion and powering on the charging line, normal power (i.e., reverse charging at a specific charging power, corresponding to the second charging power) is broadcast, and system power consumption is reduced (i.e., entering a low power mode, corresponding to the preset load mode). If the reverse charging mode is not entered, it is determined again whether to enter the extreme reverse charging mode after detecting insertion and powering on the charging line. If the reverse charging mode is not entered after the second determination, normal power is broadcast until charging ends. If the reverse charging mode is entered after the second determination, system power consumption is reduced. After reducing system power consumption, it is determined whether the mobile terminal (i.e., the electronic device) exits the extreme reverse charging mode. If the extreme reverse charging mode is not exited, the maximum power (i.e., reverse charging at the highest charging power, corresponding to the first charging power) is broadcast, and it is determined again whether the mobile terminal (i.e., the electronic device) exits the extreme reverse charging mode. The determination process is repeated until the extreme reverse charging mode is exited. If the electronic device exits the extreme reverse charging mode, normal power is broadcast until charging ends.

[0107] In an exemplary embodiment of this disclosure, such as Figure 11 As shown in the flowchart of the charging method, this disclosure controls the electronic device to perform reverse charging function in the following manner: In response to the start of reverse charging, it is determined whether to enter the extreme reverse charging mode (i.e., whether the default charging mode is the first charging mode). If the reverse charging mode is entered, after the insertion is detected and the charging line (Vbus) is powered on, reverse charging is performed using normal charging power (i.e., reverse charging with a specific charging power, i.e., reverse charging with the second charging power), and the system power consumption is reduced (i.e., entering the low power mode, entering the preset load mode). If the reverse charging mode is not entered, it is determined again whether to enter the extreme reverse charging mode after the insertion is detected and the charging line is powered on. If the reverse charging mode is not entered after the second determination, normal power is broadcast until charging ends. If the reverse charging mode is entered after the second determination, the system power consumption is reduced. After reducing the system power consumption, it is determined whether the mobile terminal (i.e., the electronic device) exits the extreme reverse charging mode. If the extreme reverse charging mode is not exited, the maximum power (i.e., reverse charging with the highest charging power) is broadcast, and it is determined again whether the mobile terminal (i.e., the electronic device) exits the extreme reverse charging mode. Repeat the judgment process until the extreme reverse charging mode is exited. If the electronic device exits the extreme reverse charging mode, a dynamic adjustment scheme (i.e., the second charging mode) is adopted to reverse charge until the charging ends.

[0108] In this embodiment, when the electronic device is reverse-charging, the current charging mode of the electronic device is determined. If the current charging mode is a first charging mode, the electronic device is controlled to enter a preset load mode and reverse-charged with a first charging power close to or equal to the maximum charging power. If the current charging mode is a second charging mode, the battery level and load level of the electronic device are determined, and the charging power of the electronic device is adjusted according to the battery level, load level, and preset correspondence, and reverse-charging is performed according to the adjusted power. During reverse charging using the first charging mode, it is monitored in real time whether the electronic device exits the preset load mode and the battery level of the electronic device is monitored. If the electronic device exits the preset load mode and / or the current battery level of the electronic device corresponds to the lowest battery level, the first charging mode is exited and reverse charging is performed using the second charging mode. Through this disclosure, when the electronic device is reverse-charging, it is possible to perform reverse charging with the maximum charging power, or to set the charging power according to the load state of the electronic device and perform reverse charging, ensuring the charging efficiency of the electronic device during reverse charging.

[0109] Based on the same concept, this disclosure also provides a reverse charging device 100.

[0110] It is understood that the reverse charging device 100 provided in this disclosure includes hardware structures and / or software modules corresponding to each function in order to achieve the above-mentioned functions. In conjunction with the units and algorithm steps of the various examples disclosed in this disclosure, this disclosure can be implemented in hardware or a combination of hardware and computer software. Whether a function is executed by hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of the technical solutions of this disclosure.

[0111] Figure 12 This is a block diagram illustrating a reverse charging device 100 according to an exemplary embodiment. (Refer to...) Figure 11 The device includes a determining unit 101 and a processing unit 102.

[0112] The determining unit 101 is used to determine the current charging mode in response to the electronic device performing reverse charging.

[0113] The processing unit 102 is used to perform reverse charging according to the reverse charging power corresponding to the current charging mode.

[0114] The charging modes of the electronic device include a first charging mode and a second charging mode. The reverse charging power corresponding to the first charging mode is different from the reverse charging power corresponding to the second charging mode.

[0115] In one embodiment, the processing unit 102 performs reverse charging according to the reverse charging power corresponding to the current charging mode in the following manner: In response to the current charging mode being a first charging mode, the load mode of the electronic device is set to a preset load mode, and the reverse charging power of the electronic device is adjusted to the first charging power. The first charging mode is a charging mode that uses the first charging power for reverse charging, and the difference between the first charging power and the maximum reverse charging power supported by the electronic device is less than a threshold. The preset load mode is a load mode in which the preset load function is disabled. Reverse charging is performed according to the first charging power.

[0116] In one embodiment, during the process of setting the load mode of the electronic device to a preset load mode, the processing unit 102 is further configured to: perform reverse charging using a second charging power, wherein the second charging power is less than the first charging power.

[0117] In one embodiment, the processing unit 102 is further configured to: in response to determining that the electronic device has exited the first charging mode, set the current charging mode of the electronic device to a second charging mode, wherein the second charging mode is a charging mode that uses a third charging power for reverse charging, and the third charging power is less than or equal to the first charging power; and perform reverse charging according to the third charging power.

[0118] In one embodiment, the processing unit 102 determines that the electronic device exits the first charging mode in the following manner: in response to determining that the electronic device exits the preset load mode and / or that the current battery power of the electronic device is less than a preset power threshold, the electronic device exits the first charging mode.

[0119] In one embodiment, the processing unit 102 determines that the electronic device exits the preset load mode in the following manner: in response to the battery temperature of the electronic device being higher than a temperature threshold and / or the electronic device activating the preset load function, the processing unit 102 determines that the electronic device exits the preset load mode.

[0120] In one embodiment, the processing unit 102 performs reverse charging based on the reverse charging power corresponding to the current charging mode in the following manner: In response to the current charging mode being a second charging mode, it determines the current battery level corresponding to the current battery level of the electronic device and the current load level of the electronic device. The electronic device includes multiple battery levels and multiple load levels, each corresponding to a different battery range. The load level of the electronic device is determined based on the battery temperature and enabled load functions. Based on the correspondence between battery level, load level, and charging power, it determines the current charging power corresponding to the current battery level and current load level, and sets this current charging power as the third charging power. Reverse charging is then performed based on the third charging power.

[0121] In one implementation, when the load level of the electronic device is fixed, the reverse charging power is positively correlated with the battery level; when the battery level of the electronic device is fixed, the reverse charging power is negatively correlated with the load level. The reverse charging power corresponding to the lowest load level and the highest battery level of the electronic device is less than or equal to a first charging power, and the highest load level and the lowest battery level of the electronic device correspond to either stopping reverse charging or the lowest reverse charging power supported by the electronic device.

[0122] In one embodiment, the determining unit 101 determines the current charging mode in the following manner: In response to the electronic device having a default reverse charging mode, the default reverse charging mode is determined as the current charging mode. Alternatively, in response to the electronic device not having a default reverse charging mode, a charging mode selection interface is displayed, showing function options for the user to select a charging mode, and the current charging mode is determined based on the function options selected by the user.
