[0051] Optionally, current wireless charging technology primarily relies on the principle of electromagnetic induction, described by Faraday's law of electromagnetic induction. Alternatively, when current passes through the coil at the transmitting end, an alternating magnetic field is generated around it. This alternating magnetic field is driven by alternating current, and its frequency and intensity depend on the characteristics of the current and the design of the coil. The design of the transmitting coil typically takes into account the coverage and efficiency of the magnetic field to ensure maximum energy transfer.

[0052] When an alternating magnetic field propagates through space and encounters a receiving coil, the change in the magnetic field induces a current in the receiving coil. This process generates an electromotive force (EMF) in the receiving coil due to the change in the magnetic field, thus producing an induced current. The induced current in the receiving coil is typically alternating current (AC), which needs to be converted to direct current (DC) by a rectification and regulation circuit to charge the receiving device. The rectification circuit is usually composed of a diode bridge, while the regulation circuit may include a voltage regulator to ensure the stability of the output voltage and current. This process enables wireless power transfer, providing a convenient charging method for various devices, especially in applications requiring reduced physical connections, such as smartphones, smartwatches, and other portable electronic devices.

[0053] Taking a mobile phone as the receiving device as an example, the charging pad contains a coil called the transmitting coil. When alternating current passes through this coil, it generates an alternating magnetic field around it. The mobile phone also contains a coil called the receiving coil. When the phone is placed on the charging pad, the receiving coil is located within the magnetic field range generated by the transmitting coil. According to the principle of electromagnetic induction, the alternating magnetic field generated by the transmitting coil will induce a current in the receiving coil. This process does not require physical contact, thus enabling wireless charging. The received alternating current is converted into direct current by a rectifier circuit, and then the voltage and current are adjusted by a regulating circuit to suit the charging requirements of the mobile phone battery.

[0054] Using the wireless charging scheme described above, there must be strict alignment between the transmitting coil and the receiving coil, resulting in low transmission efficiency and limited power transmission distance, making it only suitable for short-range wireless charging.

[0055] The technical content provided in this application aims to solve the aforementioned technical problems in related technologies. In the embodiments of this application, the charging device includes: a positioning component, a light-emitting component, and a motor. Optionally, the positioning component is configured to identify the location information of the device to be charged; the light-emitting component is connected to the positioning component and configured to emit light energy to the device to be charged based on the location information; the motor is connected to the positioning component and configured to control the movement of the positioning component according to the location information. The technical solution of this application allows the charging device to identify the location of the device to be charged and emit light energy to the device, enabling energy transmission over a longer distance, thereby achieving long-distance wireless charging.

[0056] The technical solution of this application and how it solves the above-mentioned technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0057] Example 1

[0058] Figure 1This is a schematic diagram of the structure of a charging device provided in Embodiment 1 of this application, as shown below. Figure 1 As shown, this embodiment provides a charging device, including: a positioning component 1, a light-emitting component 2, and a motor 3, wherein: the positioning component 1 is configured to identify the location information of the device to be charged; the light-emitting component 2 is connected to the positioning component 1 and is configured to emit light energy to the device to be charged based on the location information; the motor 3 is connected to the positioning component 1 and is configured to control the positioning component 1 to move according to the location information.

[0059] Optionally, the positioning component 1 is used to locate the position information of the device to be charged. After the positioning component 1 locates the position of the device to be charged, the motor 3 drives the positioning component 1 to move based on the position information. The light-emitting component 2 is connected to the positioning component 1. While the motor 3 drives the positioning component 1 to move, the light-emitting component 2 emits light energy towards the device to be charged. Optionally, the positioning component 1 and the light-emitting component 2 can be the same component, and the same component can be used to locate the device to be charged and emit light energy; alternatively, the positioning component 1 and the light-emitting component 2 can be two components, which can move synchronously or independently.

[0060] Optionally, the positioning component 1 can employ various technologies to determine the location information of the device to be charged. For example, the positioning component 1 can be an infrared sensor, determining its position by detecting the infrared signals emitted by the device; it can also be a camera, tracking the movement of the device through image recognition technology; or it can be a lidar, measuring distance and angle by emitting and receiving laser pulses to construct the spatial coordinates of the device. The combination of these technologies enables the positioning component 1 to acquire the location information of the device in real time and accurately. This information is transmitted to the motor 3, driving it to adjust the direction and angle of the light-emitting component 2, ensuring that the laser continuously and accurately illuminates the corresponding position of the device. This dynamic adjustment mechanism not only improves the efficiency of energy transmission but also reduces energy loss due to positional deviations, enabling the system to maintain high charging performance in complex and dynamic environments.

[0061] Optionally, the light-emitting component 2 can be a light-emitting tube. The design of the light-emitting component 2 aims to emit a high-intensity, narrow-beam laser for efficient energy transfer. The laser selection is typically based on its wavelength and power to ensure compatibility with different charging requirements and device types. The light-emitting component 2 needs to have good heat dissipation performance, as heat accumulation at high power output can affect its performance and lifespan. Optionally, the light-emitting component 2 is equipped with a heat sink or active cooling system to maintain its stability during long-term operation. Optionally, the material and structural design of the light-emitting component 2 also needs to take into account the reflection and refraction characteristics of the laser to maximize energy transfer efficiency.

[0062] Alternatively, as Figure 1 As shown, motor 3 includes a first motor 31 and a second motor 32; the first motor 31 and the second motor 32 are mounted on a fixed shaft and are arranged perpendicular to each other; wherein, the first motor 31 is used to move in a first direction and the second motor 32 is used to move in a direction perpendicular to the first direction.

[0063] Optionally, motor 3 is responsible for precisely adjusting the orientation of positioning component 1 and light-emitting component 2 to ensure that the laser accurately illuminates the corresponding position of the device to be charged. Motor 3 consists of a first motor 31 and a second motor 32, which are mounted on a fixed shaft and arranged perpendicularly to each other, connected to a motor drive module, which in turn is connected to a system control unit. The first motor 31 is a horizontal motor specifically designed to move positioning component 1 and light-emitting component 2 in the X direction, enabling 360° rotation. By controlling the rotation of the first motor 31, the angles of positioning component 1 and light-emitting component 2 can be adjusted in the horizontal direction. This design allows for precise angular adjustment of positioning component 1 and light-emitting component 2 in the horizontal plane to accommodate changes in the position of the device to be charged in the X direction. The accuracy and response speed of the horizontal motor are crucial for ensuring accurate laser positioning; therefore, a bus servo motor or other servo motor is typically used to achieve this function.

[0064] Optionally, the second motor 32 is a vertical motor, responsible for moving the positioning component 1 and the light-emitting component 2 in a direction perpendicular to the X direction (i.e., the Y direction), enabling a 180° rotation. Controlled by the second motor 32, the positioning component 1 and the light-emitting component 2 can be adjusted in the Y direction to adapt to changes in the position of the device to be charged. This vertical adjustment capability allows for flexible laser positioning in three-dimensional space, ensuring that the laser accurately illuminates the target position even when the height of the device to be charged changes. The vertical motor also needs to possess high precision and fast response characteristics to adapt to positional changes in dynamic environments.

[0065] In the example above, through the coordinated operation of the first and second motors, the motors can achieve omnidirectional angle adjustment, ensuring that the light-emitting component can maintain the optimal laser transmission path at all times, thereby improving charging efficiency and reliability.

[0066] In one example, the light-emitting component 2 includes an optical focusing module, a light source, and a control circuit; the optical focusing module and the control circuit are connected to focus the light source to generate a collimated beam, and the control circuit is used to adjust the output power of the collimated beam.

[0067] Optionally, the light-emitting component 2 is the core component responsible for emitting the laser, and its internal structure includes an optical focusing module, a light source, and control circuitry. The main function of the optical focusing module is to focus the light beam generated by the light source into a collimated beam. A collimated beam has high directionality and low divergence, which is crucial for long-distance energy transmission. The optical focusing module typically consists of lenses and reflectors; these optical elements are precisely designed and arranged to ensure concentrated energy and stable direction of the beam. By adjusting the curvature and position of the lenses, the optical focusing module can optimize the quality of the beam, maintaining minimal energy loss and maximum transmission efficiency during transmission.

[0068] Optionally, the control circuit in the light-emitting component 2 functions to regulate and optimize the beam output. Connected to the optical focusing module, it is responsible for adjusting the output power of the collimated beam to adapt to different charging needs and environmental conditions. The control circuit can adjust the beam intensity by changing the current or voltage of the light source, thereby achieving precise control of the laser power. This adjustment capability not only helps improve energy transfer efficiency but also ensures the system's stable performance at different distances and angles. In the example above, through the coordinated operation of the optical focusing module and the control circuit, the light-emitting component can provide efficient and stable laser output, providing reliable support for the energy transfer of the charging device.

[0069] In one example, the positioning component 1 includes a camera; the camera is used to capture the location information of the device to be charged.

[0070] Optionally, the positioning component 1 is responsible for accurately locating the device to be charged, and one of its core components is a camera. The camera establishes a communication connection with the device to be charged, enabling it to capture the light signals emitted by the device in real time. The camera's high resolution and fast capture capability allow it to accurately identify the light source information of the device to be charged in dynamic environments. This information includes light intensity, position, and flicker pattern, etc. By analyzing this data, the camera can determine the spatial position and movement state of the device to be charged. The camera is typically installed in the positioning component 1 and has a wide-angle field of view and high sensitivity to ensure effective operation under different lighting conditions.

[0071] Optionally, the camera captures the light source information of the device to be charged and transmits this data to the communication unit within the charging device. The communication unit processes and transmits the information acquired by the camera, typically using a high-speed data transmission protocol to ensure real-time performance and accuracy. By exchanging data with other components of the device to be charged, the communication unit assists the charging device in quickly adjusting the direction and output power of the light-emitting component 2 to optimize the energy transmission path. This real-time feedback mechanism not only improves the device's response speed but also enhances positioning accuracy, ensuring that the laser always accurately illuminates the corresponding position on the device to be charged.

[0072] In the example above, the positioning component provides reliable positioning support for the charging device through the coordinated work of the camera and the communication unit, ensuring efficient energy transfer in complex and dynamic environments.

[0073] Optionally, the charging device also includes a first bracket, a second bracket, and a back plate; the positioning component 1 and the light-emitting component 2 are both mounted on the first bracket and fixed to the motor 3 via a rotating shaft; the motor 3 is fixed to the back plate via the second bracket.

[0074] Optionally, the first bracket is an important load-bearing component in the charging device. Its main function is to support the positioning component 1 and the light-emitting component 2. Placing both the positioning component 1 and the light-emitting component 2 on the first bracket allows these functional components to be relatively concentrated in space, facilitating design and layout, and also promoting their electrical connection and coordinated operation. The first bracket is connected to the motor 3 via a rotating shaft, which gives the charging device a certain degree of flexibility. The main function of the second bracket is to fix the motor, providing a stable support platform to ensure that the motor does not shift due to vibration or external forces during operation. The backplate is the rear support structure of the entire charging device, serving to support and fix the entire device. The motor 3 is fixed to the backplate via the second bracket. This structure allows the motor 3 to be securely installed inside the device and also facilitates the transmission of power from the motor 3 to the first bracket.

[0075] Optionally, the optimization of function and structure is achieved through the reasonable combination of the first bracket, the second bracket and the back plate, as well as the ingenious connection between the positioning component, the light-emitting component and the motor.

[0076] Building upon the previous example, the backplane connects to a power source to supply power to the charging device. Power is also required to power the charging device during its use. The power source provides the necessary electrical support to the charging device through its connection to the backplane. The power source design typically needs to consider the overall power consumption requirements of the system to provide sufficient current and voltage to support the operation of positioning component 1, lighting component 2, motor 3, and other electronic components. The power source can be an external power adapter or a built-in battery pack, depending on the application scenario and portability requirements of the charging device. The connection between the power source and the backplane not only provides a power transmission channel but also integrates power management circuitry to monitor and regulate the power supply, ensuring stability and safety under various operating conditions.

[0077] The charging device provided in this embodiment includes a positioning component, a light-emitting component, and a motor. The positioning component is configured to identify the location information of the device to be charged. The light-emitting component is connected to the positioning component and configured to emit light energy towards the device to be charged based on the location information. The motor is connected to the positioning component and configured to control the movement of the positioning component according to the location information. The technical solution of this application allows the charging device to identify the location of the device to be charged and emit light energy towards it, enabling energy transmission over a longer distance and thus achieving long-distance wireless charging.

[0080] The solar energy receiver 5 is configured to receive solar energy to charge the device to be charged.

[0081] Optionally, the device to be charged includes a beacon component 4 and a light receiving board 5, both of which play important roles in the entire device. The beacon component 4 provides location information to the charging device, helping the positioning component 1 within the charging device to accurately identify the spatial location of the device to be charged. This is typically achieved by emitting specific signals or reflecting signals from the charging device, ensuring that the charging device can adjust the direction of the laser in real time.

[0082] Optionally, the solar energy receiving panel 5 is responsible for receiving laser light from the charging device and converting it into electrical energy to charge the device to be charged. The solar energy receiving panel 5 is typically made of highly efficient photoelectric conversion materials to maximize energy conversion efficiency. Optionally, the solar energy receiving panel 5 includes a solar panel. Optionally, the beacon assembly 4 and the solar energy receiving panel 5 can be positioned anywhere within the device to be charged; alternatively, the beacon assembly 4 and the solar energy receiving panel 5 are respectively located on the back of the device to be charged.

[0083] In one example, beacon component 4 includes a light-emitting unit, a drive control unit, and a communication unit; the drive control unit is connected to the light-emitting unit and is used to drive the light-emitting unit to emit light; the communication unit is connected to the charging device.

[0084] Optionally, the beacon component 4 assists in positioning in conjunction with the positioning component 1 in the charging device. It mainly consists of a light-emitting unit, a drive control unit, and a communication unit, and is installed on the device to be charged. The main function of the light-emitting unit is to emit identifiable light signals, which can be detected by the positioning component 1 of the charging device. The light-emitting unit is typically composed of LEDs or laser diodes, which can generate stable and controllable light output. The drive control unit is directly connected to the light-emitting unit and is responsible for adjusting and driving its operation. By adjusting the current or voltage, the drive control unit can control the brightness and flashing mode of the light-emitting unit, thereby generating specific light signals. Optionally, the drive control unit generates an adjustable constant current source to drive the LED to emit light, and controls the brightness and on / off state of the LED. Optionally, the LED light source can be a visible light source with a wavelength less than 850nm or an invisible laser source with a wavelength greater than 850nm, depending on the wavelength.

[0085] Optionally, the communication unit, responsible for data transmission within the beacon component 4, communicates with the positioning component 1 in the charging device. The communication unit can employ wireless communication technology, optionally Bluetooth, Wi-Fi, or infrared communication, to achieve real-time data exchange with the charging device. Through this connection, the beacon component 4 can transmit the location information and other status information of the device to be charged to the charging device, helping it adjust the direction and power output of the light-emitting component 2. This real-time communication and feedback mechanism ensures that the charging device can quickly respond to changes in the location of the device to be charged, maintaining efficient energy transfer. Optionally, through the coordinated operation of the light-emitting unit, the drive control unit, and the communication unit, the beacon component provides reliable positioning and communication support for the device to be charged, ensuring the accuracy and stability of energy transfer.

[0086] Optionally, after receiving the laser light, the optical energy receiving board 5 in the device to be charged needs to convert the light energy into electrical energy to charge the device. Optionally, the device to be charged also includes an electrical energy conversion module; the electrical energy conversion module is connected to the optical energy receiving board 5 and is used to convert the light energy received by the optical energy receiving board 5 into electrical energy.

[0087] Optionally, one of the key functions of the device to be charged is to convert the received light energy into usable electrical energy, a task performed by the power conversion module. The power conversion module is directly connected to the light energy receiving board 5 and is responsible for converting the laser energy captured by the light energy receiving board into electrical energy. However, the current output by the light energy receiving board 5 is typically direct current and may have unstable voltage and current characteristics, requiring further processing.

[0088] In one example, the power conversion module includes a charging control circuit and a voltage detection circuit. The charging control circuit is connected to the solar energy receiving board 5 and the voltage detection circuit for charging the device to be charged. Optionally, the charging control circuit rectifies the current generated by the solar energy receiving board 5 to eliminate any possible AC components, ensuring that the output is pure DC. Subsequently, the voltage detection circuit regulates the voltage to provide a constant output voltage and current, suitable for powering the battery or other electrical equipment of the device to be charged. Optionally, the power conversion module also integrates energy management functions to optimize energy use efficiency and protect the device to be charged from overvoltage or overcurrent. Through these functions, the power conversion module ensures efficient conversion from solar energy to electrical energy, providing reliable power support.

[0090] The following description will use a mobile terminal as an example. Those skilled in the art will understand that, apart from components specifically designed for mobile purposes, the construction according to this embodiment can also be applied to fixed-type terminals.

[0091] Please see Figure 3 This is a schematic diagram of the hardware structure of a mobile terminal implementing this embodiment. The mobile terminal 300 may include: an RF (Radio Frequency) unit 301, a WiFi module 302, an audio output unit 303, an A / V (Audio / Video) input unit 304, a sensor 305, a display unit 306, a user input unit 307, an interface unit 308, a memory 309, a processor 310, and a power supply 311, etc. Those skilled in the art will understand that... Figure 3 The mobile terminal structure shown does not constitute a limitation on the mobile terminal. The mobile terminal may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0092] The following is combined with Figure 3 A detailed introduction to each component of the mobile terminal:

[0093] The radio frequency (RF) unit 301 can be used for receiving and transmitting signals during information transmission or calls. Specifically, it receives downlink information from the base station and processes it with the processor 310; additionally, it transmits uplink data to the base station. Typically, the RF unit 301 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, and a duplexer. Furthermore, the RF unit 301 can also communicate wirelessly with networks and other devices. The aforementioned wireless communications may use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (Code Division Multiple Access 2000), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution), TDD-LTE (Time Division Duplexing-Long Term Evolution), 5G, and 6G.

[0094] WiFi is a short-range wireless transmission technology. Mobile terminals, through the WiFi module 302, can help users send and receive emails, browse web pages, and access streaming media, providing users with wireless broadband internet access. Although Figure 3 WiFi module 302 is shown, but it is understood that it is not a necessary component of a mobile terminal and can be omitted as needed without changing the nature of this application.

[0095] The audio output unit 303 can convert audio data received by the radio frequency unit 301 or the WiFi module 302 or stored in the memory 309 into audio signals and output them as sound when the mobile terminal 300 is in call signal receiving mode, call mode, recording mode, voice recognition mode, broadcast receiving mode, etc. Furthermore, the audio output unit 303 can also provide audio output related to specific functions performed by the mobile terminal 300 (e.g., call signal receiving sound, message receiving sound, etc.). The audio output unit 303 may include a speaker, earpiece, buzzer, etc.

[0096] The A / V input unit 304 is used to receive audio or video signals. The A / V input unit 304 may include a graphics processing unit (GPU) 3041 and a microphone 3042. The GPU 3041 processes image data of still images or videos acquired by an image capture device (such as a camera) in video capture mode or image capture mode. The processed image frames can be displayed on the display unit 306. The image frames processed by the GPU 3041 can be stored in the memory 309 (or other storage media) or transmitted via the radio frequency unit 301 or the WiFi module 302. The microphone 3042 can receive sound (audio data) in operating modes such as telephone call mode, recording mode, and voice recognition mode, and can process such sound into audio data. The processed audio (voice) data can be converted into a format that can be transmitted to a mobile communication base station via the radio frequency unit 301 in telephone call mode. The microphone 3042 can implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0097] The mobile terminal 300 also includes at least one sensor 305, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 3061 according to the ambient light level, and the proximity sensor can turn off the display panel 3061 and / or backlight when the mobile terminal 300 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the phone's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. Other sensors that may be configured in the phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

[0098] The display unit 306 is used to display information input by the user or information provided to the user. The display unit 306 may include a display panel 3061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0099] User input unit 307 can be used to receive input numerical or character information, and generate key signal inputs related to user settings and function control of the mobile terminal. Optionally, user input unit 307 may include touch panel 3071 and other input devices 3072. Touch panel 3071, also known as touch screen, can collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 3071), and drive corresponding connection devices according to a pre-set program. Touch panel 3071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, and sends it to processor 310, and can also receive and execute commands sent by processor 310. In addition, touch panel 3071 can be implemented using at least two types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 3071, the user input unit 307 may also include other input devices 3072. Optionally, other input devices 3072 may include, but are not limited to, one or more of the following: physical keyboard, function keys (such as volume control buttons, power buttons, etc.), trackball, mouse, joystick, etc., without being specifically limited here.

[0100] Optionally, the touch panel 3071 may cover the display panel 3061. When the touch panel 3071 detects a touch operation on or near it, it transmits the information to the processor 310 to determine the type of touch event. Subsequently, the processor 310 provides corresponding visual output on the display panel 3061 based on the type of touch event. Although in Figure 3 In this embodiment, the touch panel 3071 and the display panel 3061 are two independent components to realize the input and output functions of the mobile terminal. However, in some embodiments, the touch panel 3071 and the display panel 3061 can be integrated to realize the input and output functions of the mobile terminal. The specific implementation is not limited here.

[0101] Interface unit 308 serves as an interface through which at least one external device can connect to mobile terminal 300. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device with an identification module, an audio input / output (I / O) port, a video I / O port, a headphone port, and so on. Interface unit 308 may be used to receive input (e.g., data, power, etc.) from the external device and transmit the received input to one or more elements within mobile terminal 300, or it may be used to transmit data between mobile terminal 300 and the external device.

[0102] The memory 309 can be used to store software programs and various data. The memory 309 may primarily include a program storage area and a data storage area. Optionally, the program storage area may store the operating system, applications required for at least one function (such as sound playback, image playback, etc.), etc.; the data storage area may store data created based on the use of the mobile phone (such as audio data, phonebook, etc.). Furthermore, the memory 309 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0103] The processor 310 is the control center of the mobile terminal. It connects various parts of the mobile terminal via various interfaces and lines. By running or executing software programs and / or modules stored in the memory 309, and by calling data stored in the memory 309, it performs various functions and processes data of the mobile terminal, thereby providing overall monitoring of the mobile terminal. The processor 310 may include one or more processing units; preferably, the processor 310 may integrate an application processor and a modem processor. Optionally, the application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into the processor 310.

[0104] The mobile terminal 300 may also include a power supply 311 (such as a battery) that supplies power to various components. Preferably, the power supply 311 can be logically connected to the processor 310 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system.

[0105] although Figure 3 As not shown, the mobile terminal 300 may also include a Bluetooth module, etc., which will not be elaborated here. It is understood that the above scenarios are merely examples and do not constitute a limitation on the application scenarios of the technical solutions provided in the embodiments of this application.
