The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0069] Figure 1 This is a process of a charging method according to an exemplary embodiment. Figure 1 .like Figure 1As shown, the charging method is applied to a first electronic device including a first connector, the first connector including a first data transmission interface, and the method mainly includes the following steps:

[0070] S11. In response to detecting, through the first data transmission interface, that a second electronic device is connected, and the power level of the second electronic device does not meet a preset power condition, receiving, through the first data transmission interface, a charging request from the second electronic device; wherein the charging request carries charging parameters, and the first data transmission interface is connected to a second data transmission interface of the second electronic device;

[0071] S12: Charge the second electronic device based on the charging parameter.

[0072] In an embodiment of the present disclosure, the charging method can be applied to a first electronic device including a first connector, wherein the first electronic device can be an electronic device such as a display screen, a keyboard, a capacitive stylus, a charging stand, a projector, a headset, a printer, a game controller, etc. that can be connected to an electronic device such as a user equipment (UE), a mobile device, a user terminal, a mobile phone, a tablet computer, a personal digital assistant (PDA), a handheld device, a computing device, an in-vehicle device, a wearable device, etc. For example, the charging method of the embodiment of the present disclosure can be applied to a scenario where a keyboard charges a tablet computer. For another example, the charging method of the embodiment of the present disclosure can be applied to a scenario where a car charging stand charges a tablet computer.

[0073] In an embodiment of the present disclosure, a first electronic device includes a first connector, and the first connector includes a first data transmission interface, wherein the first connector can be a pogo pin connector, a Universal Serial Bus (USB) connector, or a High Definition Multimedia Interface (HDMI) connector, and the embodiment of the present disclosure does not impose any restrictions on this. The first data transmission interface is one of the interfaces in the first connector, such as when the first connector has a plurality of pogo pin structures, the first data transmission interface is one of the pin contacts; when the first connector is a USB connector, the first data transmission interface is an interface for connecting a USB data transmission line; when the first connector is an HDMI connector, the first data transmission interface is one or more pins of the HDMI connection.

[0074] In some embodiments, the first connector comprises a pogo pin.

[0075] In the embodiment of the present disclosure, the first connector can be an integration of multiple pogo pins, and the first data transmission interface can be one of the pogo pins in the first connector. For example, the first data transmission interface is a data pin for data transmission among multiple pogo pins. In the embodiment of the present disclosure, data transmission and connection with other electronic devices are performed through the pogo pin.

[0076] In the embodiment of the present disclosure, the provision of the pogo pin can improve the stability, durability, and corrosion resistance of the first connector, and the provision of the pogo pin is relatively simple, easy to implement, and low in cost.

[0077] In step S11, the first electronic device receives a charging request from the second electronic device through the first data transmission interface in response to detecting that the second electronic device is connected through the first data transmission interface and the power level of the second electronic device does not meet the preset power condition; wherein the charging request carries charging parameters, and the first data transmission interface is connected to the second data transmission interface of the second electronic device.

[0078] In the embodiment of the present disclosure, the second electronic device can be a user equipment (UE), a mobile device, a user terminal, a mobile phone, a tablet computer, a personal digital assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, or other electronic device.

[0079] In an embodiment of the present disclosure, the first electronic device detects whether the second electronic device is connected through the first data transmission interface. In some embodiments, the first electronic device can determine whether the second electronic device is connected by detecting the electrical parameters of the first data transmission interface. It can be understood that when the first data transmission interface is connected to the second data transmission interface of the second electronic device, the electrical parameters of the first data transmission interface (such as current value and voltage value) will change. For example, if the current value of the first data transmission interface increases instantaneously, it indicates that the second electronic device is connected; if the current value of the first data transmission interface does not change, it can be determined that the second electronic device is not connected.

[0080] In other embodiments, the first electronic device can detect whether the second electronic device is connected based on the single-wire protocol. For example, the first electronic device can set relevant parameters of the single-wire protocol and perform signal detection through the first data transmission interface. When the detected signal is the relevant parameters in the single-wire protocol, it indicates that the second electronic device is connected; otherwise, it indicates that the second electronic device is not connected.

[0081] In other embodiments, the first electronic device can determine whether the second electronic device is connected by detecting the communication status of the first data transmission interface. Specifically, the first electronic device can send a detection signal or command based on the first data transmission interface to detect whether communication can be established with the second electronic device; if communication can be established, it is determined that the second electronic device is connected; if communication cannot be established, it is determined that the second electronic device is not connected.

[0082] In other embodiments, the second electronic device can also detect whether the first electronic device is connected, and send a connection instruction or signal to the first electronic device based on the detection result. The first electronic device can receive the connection instruction or signal sent by the second electronic device through the first data transmission interface, and determine whether the second electronic device is connected through the instruction or signal.

[0083] In an embodiment of the present disclosure, the second electronic device can monitor its own power level. In some embodiments, the second electronic device includes a power meter, and the second electronic device monitors the power level through the power meter; in other embodiments, the second electronic device includes a power management module, and the second electronic device monitors the power level through the power management module; in still other embodiments, the second electronic device can monitor the power level through an installed software application. In this regard, the embodiments of the present disclosure are not limited. When the power level of the second electronic device does not meet a preset power level condition, the second electronic device can send a charging request to the first electronic device. The fact that the power level of the second electronic device does not meet the preset power level condition may mean that the power level of the second electronic device is not fully charged, or that the power level of the second electronic device is less than a preset power level threshold, for example, the power level is less than 30%.

[0084] In an embodiment of the present disclosure, a first electronic device receives a charging request from the second electronic device through the first data transmission interface in response to detecting through the first data transmission interface that a second electronic device is connected and the power level of the second electronic device does not meet a preset power condition, wherein the first data transmission interface is connected to the second data transmission interface of the second electronic device. Then, the first electronic device can receive the charging request from the second electronic device sent by the second data transmission interface through the first data transmission interface.

[0085] In the embodiment of the present disclosure, the charging request carries charging parameters, wherein the charging parameters may include charging voltage, charging current, charging power, etc. In addition, the charging request may also carry device identification information of the second device, etc.

[0086] In step S12, the first electronic device charges the second electronic device based on the charging parameters. After receiving a charging request carrying the charging parameters from the second electronic device, the first electronic device may charge the second electronic device based on the charging parameters. In some embodiments, the charging parameter is a charging voltage. The first electronic device includes a charge pump, a direct current-direct current (DC-DC) converter, a boost circuit, a buck circuit, and other voltage-adjustable devices or circuits to convert the voltage in the first electronic device into a charging voltage to charge the second electronic device.

[0087] In some embodiments, the charging parameter is a charging current. The first electronic device includes current-adjustable devices or circuits such as resistors, capacitors, and transistors, which convert the current in the first electronic device into a charging current to charge the second electronic device.

[0088] In the embodiment of the present disclosure, when the first electronic device has a device for storing electrical energy such as a battery, the second electronic device can be charged based on charging parameters through the device for storing electrical energy such as a battery of the first electronic device; when the first electronic device does not have a device for storing electrical energy such as a battery, an external power supply device can be connected to receive electrical energy provided by the power supply device, and the power supply parameters provided by the power supply device can be converted into charging parameters to charge the second electronic device.

[0089] In an embodiment of the present disclosure, a first electronic device first detects the connection of a second electronic device via a first data transmission interface. When the power level of the second electronic device does not meet a preset power condition, the first electronic device receives a charging request from the second electronic device carrying charging parameters via the first data transmission interface, and charges the second electronic device based on the charging parameters. On the one hand, electronic devices typically include a data transmission interface, and detecting whether a second electronic device is connected via the first data transmission interface reuses the data transmission interface, eliminating the need to install additional detection equipment, saving costs, and making implementation easier. On the other hand, receiving the charging request carrying charging parameters sent by the second electronic device and charging the second electronic device based on the charging parameters can improve the charging compatibility between electronic devices, improve the safety and reliability of electronic devices, save energy, and provide greater intelligence.

[0090] In some embodiments, the method further comprises:

[0091] Whether the second electronic device is connected is detected through the first data transmission interface based on the single-wire protocol.

[0092] In the embodiment of the present disclosure, as mentioned above, the first electronic device can detect whether the second electronic device is connected based on the single-line protocol through the first data transmission interface. In some embodiments, the first electronic device and the second electronic device may include a control module, such as a central processing unit (CPU), a microcontroller unit (MCU), etc. The control module in the first electronic device and the control module of the second electronic device can customize the single-line protocol, such as setting relevant parameters in the single-line protocol. The first electronic device can perform signal detection through the first data transmission interface. When the detected signal is the relevant parameter in the single-line protocol, it indicates that the second electronic device is connected. Otherwise, it indicates that the second electronic device is not connected. The relevant parameters may include data transmission rate, baud rate, etc., such as setting the data transmission rate in the single-line protocol. The data transmission rate detection is performed through the first data transmission interface. When the detected data transmission rate is the data transmission rate set in the single-line protocol, it indicates that the second electronic device is connected. Otherwise, it indicates that the second electronic device is not connected. It should be noted that in the embodiment of the present disclosure, it is also possible to determine whether the second electronic device is connected by detecting other signals. This is not limited by the embodiment of the present disclosure.

[0093] In other embodiments, the first electronic device may set an identifier of the second electronic device in the single-wire protocol and detect the identifier through the first data transmission interface. When the identifier of the second electronic device is detected, it indicates that the first electronic device is connected to the second electronic device.

[0094] In some embodiments, detecting whether the second electronic device is connected through the first data transmission interface based on a single-wire protocol includes:

[0095] At preset time intervals, detecting whether the second electronic device is connected is performed through the first data transmission interface based on the single-wire protocol.

[0096] In an embodiment of the present disclosure, a first electronic device may detect whether it is connected to a second electronic device through a first data transmission interface based on a single-wire protocol at a preset time interval, wherein the preset time interval is a set value and may be changed according to specific circumstances. Specifically, it may be changed according to the power level of the second electronic device. For example, when the power level of the second electronic device is greater than 80%, the preset time interval may be set to 10 seconds; when the power level of the second electronic device is less than 80%, the preset time interval may be set to 5 seconds. It is understood that the preset time interval may not be changed according to the power level of the second electronic device, such as being set to 10 seconds, and this is not limited in the embodiment of the present disclosure.

[0097] In the embodiment of the present disclosure, the setting of the preset time interval can improve the timeliness of electronic device detection, help to timely discover the connection and disconnection of the device, and provide timely information feedback for subsequent processing operations.

[0098] In an embodiment of the present disclosure, a first electronic device detects whether a second electronic device is connected through a first data transmission interface based on a single-wire protocol. Since the single-wire protocol is a communication protocol customized by the first electronic device and the second electronic device, detecting whether a second electronic device is connected through the single-wire protocol can enhance the accuracy and reliability of detection and is more intelligent.

[0099] In some embodiments, in response to detecting, through the first data transmission interface, that a second electronic device is connected and the power level of the second electronic device does not meet a preset power level condition, receiving, through the first data transmission interface, a charging request from the second electronic device, includes:

[0100] In response to detecting that the second electronic device is connected through the first data transmission interface, performing identity authentication with the second electronic device based on the single-wire protocol through the first data transmission interface;

[0101] In response to the identity authentication being passed and the power level of the second electronic device not meeting the preset power level condition, a charging request from the second electronic device is received through the first data transmission interface.

[0102] In an embodiment of the present disclosure, in response to detecting that a second electronic device is connected through a first data transmission interface, the first electronic device performs identity authentication with the second electronic device through the first data transmission interface based on a single-line protocol; in some embodiments, the first electronic device can perform identity authentication with the second electronic device through the first data transmission interface based on the identity information and identity password specified in the single-line protocol. For example, in response to detecting that a second electronic device is connected through the first data transmission interface, the first electronic device can send an identity authentication request to the second electronic device based on the first data transmission interface, and the identity authentication request carries the identity information specified in the single-line protocol (such as device identification, user name, etc.). After receiving the identity authentication request, the second electronic device enters the identity password corresponding to the identity information in the single-line protocol to complete the identity authentication.

[0103] In other embodiments, the first electronic device may authenticate the second electronic device based on an encryption algorithm in the single-wire protocol. In other embodiments, the first electronic device may authenticate the second electronic device based on a specific data format and instructions in the single-wire protocol. This is not limited in the present disclosure.

[0104] In an embodiment of the present disclosure, a first electronic device receives a charging request from a second electronic device via a first data transmission interface in response to successful identity authentication and the second electronic device's power level not meeting a preset power level condition. Successful identity authentication between the first and second electronic devices indicates successful pairing of the first and second electronic devices, and the first electronic device has permission to charge the second electronic device.

[0105] In an embodiment of the present disclosure, in response to detecting that a second electronic device is connected, the first electronic device performs identity authentication with the second electronic device based on a single-wire protocol through a first data transmission interface, and in response to passing the identity authentication and the power level of the second electronic device not meeting a preset power condition, receives a charging request from the second electronic device through the first data transmission interface. This can improve the security of communication between the first electronic device and the second electronic device and the reliability of charging, eliminate the need for identity authentication for each communication, and can also improve communication efficiency. In addition, the identity authentication method based on the single-wire protocol is more flexible.

[0106] In some embodiments, charging the second electronic device based on the charging parameter includes:

[0107] In response to the first electronic device being connected to an external power supply device, the second electronic device is charged after converting the power supply parameters provided by the external power supply device into the charging parameters.

[0108] In an embodiment of the present disclosure, in response to a first electronic device being connected to an external power supply device, the power supply parameters provided by the external power supply device are converted into charging parameters before charging the second electronic device. As previously mentioned, the charging parameters may be charging voltage, charging current, etc. The first electronic device may first detect the power supply parameters of the external power supply device based on the charging parameters, and then convert the power supply parameters into charging parameters to charge the second electronic device. For example, when the charging parameter is charging voltage, the first electronic device may first detect the power supply voltage provided by the external power supply device, and then convert the power supply voltage into a charging voltage to charge the second electronic device. Specifically, the first electronic device may include a DC-DC converter, and the first electronic device may convert the power supply voltage provided by the external power supply device into a charging voltage through the DC-DC converter.

[0109] In an embodiment of the present disclosure, when a first electronic device is connected to an external power supply device, the power supply parameters provided by the external power supply device are converted into charging parameters and then used to charge a second electronic device. This enables the first electronic device to automatically adjust the output voltage and current according to the charging requirements of the second electronic device, thereby realizing an automated charging process and improving the convenience and efficiency of charging.

[0119] In an embodiment of the present disclosure, the second electronic device can also detect its own power level, and when it detects that it is connected to the first electronic device and the power level does not meet the preset power level condition, it sends a charging request carrying charging parameters to the first electronic device through the second data transmission interface, wherein the second data transmission interface is connected to the first data transmission interface of the first electronic device, then the second electronic device can send a charging request to the first data transmission interface through the second data transmission interface.

[0120] In the embodiments of the present disclosure, as previously described, the second electronic device may monitor its own power level via a power meter, a power detection module, a software application, or the like, and the embodiments of the present disclosure are not limited thereto. The fact that the power level of the second electronic device does not meet the preset power level condition may mean that the power level of the second electronic device is not fully charged, or that the power level of the second electronic device is less than a preset power level threshold, such as less than 30%, and the embodiments of the present disclosure are not limited thereto.

[0121] In the embodiment of the present disclosure, the charging request carries charging parameters, where, as mentioned above, the charging parameters may include charging voltage, charging current, charging power, etc. In addition, the charging request may also carry device identification information of the second device, etc.

On the one hand, electronic devices typically include a data transmission interface, and detecting whether a second electronic device is connected via the second data transmission interface reuses the data transmission interface, eliminating the need to install additional detection equipment, saving costs, and making implementation easier. On the other hand, sending a charging request carrying charging parameters to the first electronic device and receiving power provided by the first electronic device based on the charging parameters can improve charging compatibility between electronic devices, enhance the safety and reliability of electronic devices, and provide greater intelligence.

[0124] In some embodiments, the method further comprises:

[0126] In an embodiment of the present disclosure, as mentioned above, the second electronic device can detect whether the first electronic device is connected based on the single-line protocol through the second data transmission interface. The first electronic device and the second electronic device may include a control module, such as a CPU, an MCU, etc. The control module in the first electronic device and the control module of the second electronic device can customize the single-line protocol, such as setting relevant parameters in the single-line protocol. The second electronic device can perform signal detection through the second data transmission interface. When the detected signal is the relevant parameter in the single-line protocol, it indicates that the first electronic device is connected. Otherwise, it indicates that the first electronic device is not connected. The relevant parameters may include data transmission rate, baud rate, etc., such as setting the data transmission rate in the single-line protocol. The data transmission rate is detected through the second data transmission interface. When the detected data transmission rate is the data transmission rate set in the single-line protocol, it indicates that the first electronic device is connected. Otherwise, it indicates that the first electronic device is not connected. It should be noted that in the embodiment of the present disclosure, it is also possible to determine whether the first electronic device is connected by detecting other signals. The embodiment of the present disclosure does not limit this.

[0127] As mentioned above, the second electronic device may also set the identifier of the first electronic device in the single-wire protocol and detect the identifier through the second data transmission interface. When the identifier of the first electronic device is detected, it indicates that the second electronic device is connected to the first electronic device.

[0128] In some embodiments, detecting whether the first electronic device is connected through the second data transmission interface based on a single-wire protocol includes:

[0129] At preset time intervals, detecting whether the first electronic device is connected is performed through the second data transmission interface based on the single-wire protocol.

[0130] In an embodiment of the present disclosure, a second electronic device may detect whether it is connected to a first electronic device via a second data transmission interface based on a single-wire protocol at a preset time interval. As previously described, the preset time interval is a set value that may be changed according to specific circumstances. Specifically, it may be changed according to the power level of the second electronic device. For example, when the power level of the second electronic device is greater than 80%, the preset time interval may be set to 10 seconds; and when the power level of the second electronic device is less than 80%, the preset time interval may be set to 5 seconds. It is understood that the preset time interval may not be changed according to the power level of the second electronic device, such as being set to 10 seconds, and this is not limited in the embodiment of the present disclosure.

[0132] In an embodiment of the present disclosure, the second electronic device detects whether it is connected to the first electronic device based on a single-wire protocol through a second data transmission interface. Since the single-wire protocol is a communication protocol customized by the first electronic device and the second electronic device, detecting whether the first electronic device is connected through the single-wire protocol can enhance the accuracy and reliability of detection and is more intelligent.

[0133] In some embodiments, in response to detecting that the first electronic device is connected through the second data transmission interface and the power level of the second electronic device does not meet a preset power condition, sending a charging request to the first electronic device through the second data transmission interface includes:

[0134] In response to detecting that the first electronic device is connected through the second data transmission interface, performing identity authentication with the first electronic device based on the single-wire protocol through the second data transmission interface;

[0135] In response to the identity authentication being passed and the power level of the second electronic device not meeting the preset power level condition, a charging request is sent to the first electronic device through the second data transmission interface.

[0136] In the embodiment of the present disclosure, as mentioned above, the second electronic device can perform identity authentication with the first electronic device through the second data transmission interface based on the identity information and identity password specified in the single-line protocol. For example, in response to detecting that the first electronic device is connected through the first data transmission interface, the second electronic device can receive an identity authentication request sent by the first electronic device based on the second data transmission interface, which carries the identity information specified in the single-line protocol (such as device identification, user name, etc.), and enter the identity password corresponding to the identity information in the single-line protocol to complete the identity authentication. It should be noted that the second electronic device can also send an identity authentication request to the first electronic device, and the first electronic device can enter the identity password. This is not limited by the embodiment of the present disclosure.

[0137] As previously mentioned, the second electronic device can also authenticate itself with the first electronic device based on an encryption algorithm in the single-wire protocol. The second electronic device can also authenticate itself with the first electronic device based on specific data formats and instructions in the single-wire protocol. This disclosure does not limit this.

[0138] In the disclosed embodiment, in response to successful identity authentication and the second electronic device's power level not meeting a preset power level condition, the second electronic device sends a charging request to the first electronic device via the second data transmission interface. Successful identity authentication between the first and second electronic devices indicates successful pairing of the first and second electronic devices, and the first electronic device has permission to charge the second electronic device.

[0139] In an embodiment of the present disclosure, in response to detecting that a first electronic device is connected, the second electronic device performs identity authentication with the first electronic device through a second data transmission interface based on a single-line protocol, and in response to passing the identity authentication and the power level of the second electronic device not meeting a preset power condition, a charging request is sent to the first electronic device through the second data transmission interface. This can improve the security of communication between the first electronic device and the second electronic device and the reliability of charging, eliminate the need for identity authentication for each communication, and can also improve communication efficiency. In addition, the identity authentication method based on the single-line protocol is more flexible.

[0140] In some embodiments, the method further comprises:

[0141] During the charging process of the second electronic device, monitoring the power level of the second electronic device;

[0142] The charging parameter is determined according to the power amount.

[0143] In the embodiment of the present disclosure, the second electronic device can also monitor the power level of the second electronic device during the charging process, wherein the second electronic device can monitor the power level of the second electronic device in real time or at preset time intervals.

[0145] In an embodiment of the present disclosure, the second electronic device determines the charging parameters based on the power level. In some embodiments, the second electronic device may determine the charging parameters based only on the power level of the second electronic device. For example, when the charging parameter is the charging current, the charging current determined by the second electronic device when the power level is less than 20% is less than the charging current determined by the second electronic device when the power level is greater than 20% and less than 50%.

[0146] In other embodiments, the second electronic device may further determine a charging threshold based on the usage scenario and needs of the second electronic device, and determine charging parameters based on the charging threshold and the current power level. For example, if the second electronic device needs to operate for a long time, a charging threshold of 80% or 90% may be selected; if the device is mainly used for short periods of time, a charging threshold of 50% or 60% may be selected. The required charging power and charging time are then calculated based on the current power level and the charging threshold to determine the charging parameters.

[0147] In other embodiments, the second electronic device may also jointly determine charging parameters based on the power level of the second electronic device and the charging mode supported by the second electronic device. For example, if the second electronic device supports fast charging, the fast charging function may be enabled and the charging parameters may be appropriately increased to shorten the charging time.

[0148] In other embodiments, the second electronic device may also determine the charging parameters based on the power level and the temperature of the second electronic device. This is not limited in the embodiments of the present disclosure.

[0149] The disclosed embodiment monitors the power level of the second electronic device and determines charging parameters based on the power level, thereby improving the accuracy of the charging parameters and making the system more intelligent.
