[0029] In addition, "a plurality of" in the embodiments of the present application means two or more. In view of this, "a plurality of" in the embodiments of the present application can also be understood as "at least two".

[0031] Before introducing the charging device and the terminal device of the present application, the relevant background information of the embodiments of the present application will be introduced first.

[0032] In the existing charging system, the interaction between the charging device and the terminal device is extremely limited. During the charging process, the terminal device can mostly only passively receive power and knows very little about many important characteristics of the charging power source, such as battery power, battery capacity, current capacity, number of battery strings, battery power, battery status, etc. This information asymmetry makes the terminal device have obvious blindness in charging management. For example, when abnormal events occur in the charging power source, such as overcurrent, overvoltage, or too high temperature, etc., the terminal device cannot obtain this information in time and still charges according to the conventional mode, inevitably increasing the risk of causing irreversible damage to the battery of the terminal device.

[0033] Over time, the service life of the battery will be greatly shortened, which not only brings economic losses to users but also affects the normal use experience of the device. In addition, due to the lack of mastery of key parameters such as the peak current of the power source and the internal temperature, it is difficult for the terminal device to adjust the charging strategy according to the actual situation of the charging power source and cannot achieve truly healthy charging.

[0034] With the rapid development of technology and the continuous improvement of user needs, the existing charging technologies can no longer meet people's growing pursuit of charging safety, efficiency, and intelligence. Users expect that during the charging process, not only can the safety of the terminal device and the health of the battery be ensured, but also they can deeply understand the working status and detailed parameters of the charging power supply. However, the information interaction mode between the current charging devices and terminal devices is relatively simple, with relatively single functions, unable to provide comprehensive and accurate charging power supply information, and it is also difficult to support the terminal device to perform scientific and reasonable charging management based on this information.

[0035] Based on this, the embodiments of the present application provide a charging device and a terminal device, which will be described in detail below respectively.

[0036] Please refer to Figure 1 , Figure 1 FIG. is a schematic diagram of an application scenario of the charging device provided in the embodiments of the present application. The charging device 100 can be connected to the terminal device 200 and the power conversion device 300 through data lines respectively to realize information interaction with the terminal device 200 and the power conversion device 300.

[0037] Among them, the charging device 100 can be a power supply device such as a backup power supply, a charging power supply, a mobile power supply, a power bank, etc. The terminal device 200 can be a mobile terminal device such as a mobile phone, a tablet computer, a laptop computer, a smart watch, etc. The power conversion device 300 can be a hardware device such as a power adapter, a charger, an interface converter, etc.

[0038] Those skilled in the art can understand that Figure 1 the application environment shown in FIG. is only an application scenario adapted to the solution of the present application, and does not constitute a limitation on the application scenario of the solution of the present application. The charging device 100 of the present application can be applied in application scenarios such as communication, power equipment, screen mirroring interaction, etc., and specifically, it is not limited here.

[0039] First, the embodiments of the present application provide a charging device. Please refer to Figure 2 , Figure 2It is a schematic diagram of a module of a charging device provided in an embodiment of the present application. The charging device 100 may include a first interface 110, a second interface 120, and a control module 130. Among them, the first interface 110 may be used to connect to a terminal device 200. The second interface 120 may be used to connect to a power conversion device 300. The control module 130 is respectively connected to the first interface 110 and the second interface 120, and may be used to send device information and device information to the terminal device 200 in response to a power management communication instruction, so that the terminal device 200 can present the device information and the device information, and perform charging management according to the device information and the device information. Among them, the power management communication instruction comes from the terminal device 200, the device information is the information of the charging device 100, and the device information is the information of the power conversion device 300.

[0040] In an embodiment of the present application, both the first interface 110 and the second interface 120 may adopt a USB Type-C interface. Among them, the first interface 110 may be a Type-C male head, and the second interface 120 may be a Type-C female socket. It can be understood that in some other application scenarios, the first interface 110 may also be a Type-C female socket, and the second interface 120 may also be a Type-C male head. The types of the first interface 110 and the second interface 120 may be determined according to the actual application scenario, and are not limited here.

[0041] The terminal device 200 may be configured with a docking interface matching the first interface 110, and is connected to the first interface 110 through the docking interface to access the charging device 100. Similarly, the power conversion device 300 may also be configured with a docking interface matching the second interface 120, and is connected to the second interface 120 through the docking interface to access the charging device 100.

[0042] The control module 130 is respectively connected to the first interface 110 and the second interface 120. The control module 130 may perform PD (Power Delivery, power management) communication with the terminal device 200 through the first interface 110 and with the power conversion device 300 through the second interface 120 respectively. It can be understood that PD communication is the core mechanism for power negotiation and data transmission between devices in the USB Power Delivery protocol, and mainly realizes intelligent power distribution and safety control based on the USB Type-C interface.

[0043] When the power conversion device 300 is connected to the second interface 120, the control module 130 conducts PD communication with it through the second interface 120, so as to obtain the device information of the power conversion device 300 and store it; when the terminal device 200 is connected to the first interface 110, it can conduct PD communication with the control module 130 through the first interface 110, for example, sending a power management communication instruction to the control module 130, so as to obtain the device information of the charging device 100 itself and the stored device information of the power conversion device 300.

[0044] Among them, the device information may include but is not limited to VID (Vendor ID) information, PID (Product ID) information, number of battery strings, maximum power, power peak current, current capacity information, current battery status information, current internal temperature information, current output voltage, current output current, current power status, whether the charging device is a DC power supply or an AC power supply, whether it is currently powered by the battery or by the power conversion device 300, current abnormal events such as over-current protection (OCP), over-temperature protection (OTP), over-voltage protection (OVP), charge fault (CF), constant voltage charging (CV), etc.; the device information may include but is not limited to rated power, input and output voltage range, current amount, etc.

[0045] After the terminal device 200 obtains the device information and the device information, it can display the obtained relevant information to the user, for example, presenting it to the user in the form of a display screen interface or a pop-up window, so that the user can independently select a suitable charging strategy through the presented information, such as reducing the charging voltage, reducing the charging current, extending the charging time, increasing the charging speed, reducing the charging temperature, switching from the charging device power supply to the power conversion device power supply, charging with the battery, etc., healthy charging strategies.

[0046] The terminal device 200 can also analyze the obtained information while presenting the foregoing information, and infer a better charging strategy through a pre-set program or a trained model, so as to recommend the charging strategy to the user for better charging management.

[0047] The charging device 100 provided by the embodiment of the present application is configured with a first interface 110 to connect to the terminal device 200 and a second interface 120 to connect to the power conversion device 300. The control module 130 responds to the power management communication instruction of the terminal device 200 and sends the device information of the charging device 100 itself and the device information of the power conversion device 300 to the terminal device 200, realizing the comprehensive acquisition of charging-related information by the terminal device 200. In this way, the limitation of information interaction between traditional charging devices and terminal devices is broken, enabling users to deeply understand the device conditions of the connected charging devices, such as key parameters like battery power and battery capacity. Moreover, based on this information, the terminal device 200 can perform charging management, dynamically adjust the charging strategy according to real-time states such as the peak power current and internal temperature, effectively avoiding damage to the battery of the terminal device caused by abnormal events or unreasonable charging parameters, realizing a healthier charging process, improving the reliability of the charging device 100, extending the service life of the battery of the terminal device, and enhancing the intelligent level and user experience of the collaborative work between the charging device 100 and the terminal device 200.

[0048] Next, continue to Figure 2 elaborate in detail on each module shown and the specific implementation manners that may be adopted in practical applications.

[0049] As Figure 3 shown, in some embodiments of the present application, the first interface 110 is configured with a first male pin and a second male pin. The control module 130 includes a first control unit 1301, which is respectively connected to the first male pin and the second male pin, and can be used to perform power management communication with the terminal device 200 when the terminal device 200 is connected to the first male pin and the second male pin, so as to send device information and device information.

[0050] In the embodiment of the present application, the first male pin and the second male pin may be two channel configuration (Configuraon Channel, CC) pins of a Type-C male head, that is, the CC1 pin and the CC2 pin of the Type-C male head; the first control unit 1301 may be any existing PD controller.

[0051] When the terminal device 200 is connected to the first male pin and the second male pin, it can perform PD communication with the charging device 100 and send a power management communication instruction to the first control unit 1301 through the first male pin and the second male pin to obtain device information and devices.

[0052] For example, the vendor information of the charging device 100 is obtained through VDM (Vendor_Defined Message) communication of the PD communication protocol; specifically, through the Get_Source_Cap_Extended command, the VID information, PID information, number of battery strings, maximum power, and peak power current of the charging device 100 are obtained; through the Get_Battery_Cap_Message command, the current capacity information and the current battery status information of the charging device 100 are obtained; through the Get_Status_Message command, the current internal temperature information of the charging device 100, whether the charging device is a DC power supply or an AC power supply, whether it is currently powered by the battery or by the AC, and abnormal events of the power supply, including OCP, OTP, OVP, CF, CV, etc. are obtained; through the Get_PPS_Status_Message command, the current output voltage, output current, and current power status of the charging device 100 are obtained.

[0053] Please continue to refer to Figure 3 , in some embodiments of the present application, the second interface 120 is configured with a first female socket pin and a second female socket pin, and the control module 130 includes a second control unit 1302, which is respectively connected to the first female socket pin and the second female socket pin, and is used to perform power management communication with the power conversion device 300 when the power conversion device 300 is connected to the first female socket pin and the second female socket pin, so as to obtain device information.

[0054] In the embodiments of the present application, the first female socket pin and the second female socket pin may be two CC pins of a Type-C female socket, that is, the CC1 pin and the CC2 pin of the Type-C female socket; the second control unit 1302 may also be any existing PD controller; it can be understood that, in some embodiments, the second control unit 1302 may be integrated with the first control unit 1301 into the same control unit, and perform PD communication with the terminal device 200 and the power conversion device 300 respectively through time-division multiplexing.

[0055] When the power conversion device 300 is connected to the first female socket pin and the second female socket pin, the charging device 100 can perform PD communication with the power conversion device 300, and the second control unit 1302 sends a power management communication instruction to the power conversion device 300 through the first female socket pin and the second female socket pin to obtain device information, such as rated power, input and output voltage ranges, current amount, etc.

[0056] It can be understood that in some embodiments, the control module 130 may further include a main control unit 1303, which can be respectively connected to the first control unit 1301 and the second control unit 1302, and is used to control the first control unit 1301 to perform PD communication with the terminal device 200, and control the second control unit 1302 to perform PD communication with the power conversion device 300.

[0057] The main control unit 1303 can be any existing controller, including but not limited to a microcontroller unit (MCU), a system on chip (SOC), a single-chip microcomputer, etc., and can be specifically determined according to the actual application scenario.

[0058] As Figure 4 shown, in some embodiments of the present application, the first interface 110 is further configured with a first communication pin and a second communication pin, and the control module 130 further includes a first communication unit 1304, which is respectively connected to the first communication pin and the second communication pin, and can be used to perform serial bus communication with the terminal device 200 when the terminal device 200 accesses the first communication pin and the second communication pin.

[0059] In the embodiments of the present application, the first communication pin and the second communication pin can be differential pair pins for USB 2.0 connection, such as DP pins and DM pins; the first communication unit 1304 can be any existing universal serial bus (USB) module.

[0060] When the communication interface of the terminal device 200 accesses the first communication pin and the second communication pin, the first communication unit 1304 can perform USB communication with the terminal device; for example, perform HID (Human Interface Device) communication according to the USB HID protocol, and identify the inserted terminal device through descriptors, etc.

[0061] As Figure 5As shown, in some embodiments of the present application, the first interface 110 is further configured with male power pins. The charging device 100 may further include a charge and discharge module 140, which is respectively connected to the male power pins and the control module 130. The control module 130 may be configured to output a first control signal kz_1 to the charge and discharge module 140 when the terminal device 200 is connected to the first interface 110 and the power conversion device 300 is not connected to the second interface 120. The charge and discharge module 140 may be configured to generate a first voltage signal adapted to the terminal device 200 in response to the first control signal kz_1 and output it to the male power pins to charge the terminal device 200, wherein the male power pins are connected to the power supply terminal of the terminal device 200.

[0062] As an example, when the control module 130 detects that the terminal device 200 is connected to the first interface 110, it may perform PD communication with the terminal device 200 to obtain the power parameters of the terminal device 200, such as voltage parameters. If the control module 130 does not detect the connection of the power conversion device 300, the terminal device 200 may act as a power receiving party, and the control module 130 outputs the first control signal kz_1 to the charge and discharge module 140, so that the charge and discharge module 140 can output the first voltage signal to the male power pins in response to the first control signal kz_1. It can be understood that the first voltage signal may be adapted to the obtained voltage parameters of the terminal device 200, so that the male power pins can transmit the first voltage signal to the power supply terminal of the terminal device 200 to charge the terminal device 200 based on the first voltage signal.

[0063] As Figure 6 As shown, in some embodiments of the present application, the charge and discharge module 140 may include a battery unit 1401 and a voltage conversion unit 1402. The voltage conversion unit 1402 is respectively connected to the control module 130, the battery unit 1401, and the male power pins, and may be configured to convert the battery voltage signal from the battery unit 1401 into a first voltage signal in response to the first control signal kz_1 and output it to the male power pins.

[0064] In the embodiments of the present application, the battery unit 1401 may include one or more series-connected rechargeable batteries. The one or more series-connected rechargeable batteries may generate a battery voltage signal and output it to the voltage conversion unit 1402. The amplitude of the battery voltage signal may be determined according to the voltage parameters and the series connection number of the rechargeable batteries, such as 3V, 12V, 18V, etc.

[0065] The voltage conversion unit 1402 may be a direct current to direct current (DC-DC) converter. The first control signal kz_1 may be a digital signal output from the inter-integrated circuit (IIC) port of the control module 130, or an analog signal output from the digital to analog converter (DAC) port of the control module 130. The type of the first control signal kz_1 may be specifically determined according to the actual application scenario and is not limited herein.

[0066] In response to the first control signal kz_1, the voltage conversion unit 1402 may boost or buck the battery voltage signal, so as to convert the battery voltage signal into a first voltage signal adapted to the terminal device 200, and output the first voltage signal to the power supply terminal of the terminal device 200 through the male power pin, thereby charging the terminal device 200.

[0067] As Figure 7 shown, in some embodiments of the present application, the second interface 120 is further configured with a female power pin, and the female power pin is connected to the voltage conversion unit 1402; the control module 130 may be configured to output a second control signal kz_2 to the voltage conversion unit 1402 when the power conversion device 300 is connected to the second interface 120 and the terminal device 200 is not connected to the first interface 110; the voltage conversion unit 1402 may further be configured to convert the power supply voltage signal from the power conversion device 300 into a charging voltage signal adapted to the battery unit 1401 in response to the second control signal kz_2, so as to charge the battery unit 1401, wherein the female power pin is connected to the power supply voltage output terminal of the power conversion device 300.

[0068] In the embodiments of the present application, when the control module 130 does not detect the connection of the terminal device 200 and determines through PD communication that the second interface 120 is connected to the power conversion device 300, the power conversion device 300 may be used as a source end. At this time, the control module 130 may output the second control signal kz_2 to the voltage conversion unit 1402, so that the voltage conversion unit 1402 may boost or buck the power supply voltage signal output from the female power pin according to the voltage parameter of the battery unit 1401, so as to convert the power supply voltage signal into a charging voltage signal adapted to the battery unit 1401 and output the charging voltage signal to the battery unit 1401 to charge the battery unit 1401.

[0069] It can be understood that the power conversion device 300 can be connected to the AC mains power supply, and perform a series of processes on the connected AC mains power supply, such as rectification, filtering, voltage regulation, etc., to convert the AC mains power supply into a DC supply voltage signal and output it to the female socket power pin.

[0070] As Figure 8 shown, in some embodiments of the present application, the charging device 100 further includes a switch module 150, and the switch module 150 is respectively connected to the male socket power pin, the female socket power pin, and the control module 130; the control module 130 can also be used to output a switch enable signal EN to the switch module 150 when the terminal device 200 is connected to the first interface 110 and the power conversion device 300 is connected to the second interface 120; the switch module 150 can be used to electrically conduct between the female socket power pin and the male socket power pin in response to the switch enable signal EN.

[0071] In the embodiments of the present application, on the basis of the Figure 7 corresponding embodiments, when the control module 130 monitors that the terminal device 200 such as a mobile phone, a tablet computer, a notebook computer, etc. is connected to the first interface 110, the terminal device 200 can be used as the power receiving party, and at this time, the control module 130 can output the switch enable signal EN to the switch module 150 through the General-Purpose Input / Output (GPIO) port.

[0072] It can be understood that the switch enable signal EN can be active high or active low, and can be specifically determined according to the configuration of the switch module 150, which is not limited herein.

[0073] In response to the switch enable signal EN, when the switch module 150 is turned on, the female socket power pin and the male socket power pin are electrically conducted, and the supply voltage signal output by the power conversion device 300 to the female socket power pin can be directly bypassed and output to the male socket power pin, and the terminal device 200 can be fast charged through the male socket power pin. It can be understood that when the power supply is sufficient and there is a surplus, the power conversion device 300 can not only fast charge the terminal device 200 through the turned-on switch module 150, but also charge the battery unit 1401 through the voltage conversion unit 1402.

[0074] In this embodiment, the switch module 150 may include a switching transistor or a switching circuit composed of switching transistors. The switching transistor may be any existing controllable transistor, including but not limited to a triode. For example, NPN BJTs and PNP BJTs in bipolar junction transistors (BJTs), N-type MOSFETs and P-type MOSFETs in metal-oxide-semiconductor field-effect transistors (MOSFETs), etc. Specifically, it can be selected according to the actual application scenario and is not limited here.

[0075] As an example, the switch module 150 is configured to be enabled by a high level. The enable terminal of the switch module 150 is connected to a GPIO port of the control module 130. The first terminal of the switch module 150 is connected to the female socket power pin, and the second terminal is connected to the male plug power pin. When the control module 130 does not detect the access of the terminal device 200, this GPIO port remains at a low level. When it detects the access of the terminal device 200 to the first interface 110, the control module 130 outputs a high-level switch enable signal EN to the switch module 150 to drive the switch module 150 to conduct, so that electrical conduction is achieved between the female socket power pin and the male plug power pin, realizing charging of the terminal device 200.

[0076] As another example, the switch module 150 is configured to be enabled by a low level. The enable terminal of the switch module 150 is connected to a GPIO port of the control module 130. The first terminal of the switch module 150 is connected to the female socket power pin, and the second terminal is connected to the male plug power pin. When the control module 130 does not detect the access of the terminal device 200, this GPIO port remains at a high level. When it detects the access of the terminal device 200 to the first interface 110, the control module 130 outputs a low-level switch enable signal EN to the switch module 150 to drive the switch module 150 to conduct, so that electrical conduction is achieved between the female socket power pin and the male plug power pin, realizing fast charging of the terminal device 200.

[0077] Based on the above embodiments, the embodiments of the present application further provide a terminal device. Please refer to Figure 9, the terminal device 200 may include a device interface 210 and a main control module 220; wherein, the device interface 210 is used to connect to the charging device 100; the main control module 220 is connected to the device interface 210 and is used to output a power management communication instruction to obtain the device information of the charging device 100 and the device information of the power conversion device 300 when the device interface 210 is connected to the charging device 100, control the device information and the device information to be presented on a display screen (not shown in the figure), and perform charging management according to the device information and the device information; wherein, the power conversion device 300 is a power supply device connected to the charging device.

[0078] In the embodiment of the present application, the main control module 220 may adopt any existing controller such as an MCU, an SOC or a single-chip microcomputer; the device interface 210 may be a USB Type-C interface, and the USB Type-C interface may also include a CC1 pin and a CC2 pin; when the terminal device 200 accesses the charging device 100, its main control module 220 may perform PD communication with the charging device 100 through the CC1 pin and the CC2 pin, so as to obtain the device information and the device information.

[0079] For example, the main control module 220 obtains the manufacturer information of the charging device 100 through the VDM communication of the PD communication protocol; specifically, through the Get_Source_Cap_Extended command, it obtains the VID information, PID information, number of battery strings, maximum power and power peak current of the charging device 100; through the Get_Battery_Cap_Message command, it obtains the current capacity information and the current battery status information of the charging device 100; through the Get_Status_Message command, it obtains the current internal temperature information of the charging device 100, whether the charging device is a DC power supply or an AC power supply, whether it is currently powered by the battery or by the AC, and the abnormal events of the power supply, including OCP, OTP, OVP, CF, CV, etc.; through the Get_PPS_Status_Message command, it obtains the current output voltage, output current and the current power status of the charging device 100, etc.

[0080] After the main control module 220 obtains the device information and the device information, it may display the obtained relevant information to the user, for example, present it to the user in the form of a display screen interface or a pop-up window, so that the user can independently select a suitable charging strategy through the presented information, such as reducing the charging voltage, reducing the charging current, extending the charging time, accelerating the charging speed, reducing the charging temperature, switching from the charging device power supply to the power conversion device power supply, using the battery to charge and other healthy charging strategies.

[0081] In some embodiments of the present application, while presenting the foregoing information, the main control module 220 may also adjust at least one of the charging voltage, charging current, power supply, charging speed, charging temperature, and charging duration according to the acquired information; wherein, the charging voltage, charging current, and power supply are from the charging device 100, and here the power supply may be a battery or an external source such as AC mains.

[0082] The main control module 220 may analyze the acquired information, infer a better charging strategy through a preset program or a trained model, and automatically adjust the foregoing charging-related parameters according to the better charging strategy to facilitate better charging management.

[0083] For example, when it is acquired that the maximum charging current supported by the charging device 100 is "5A" and the current battery temperature of the terminal device 200 is relatively high, reaching "45°C", in order to protect the battery, the main control module 220 may adjust the charging current. Assuming that the original charging current is set to "5A", the main control module 220 reduces the charging current to "3A" according to the preset rules and appropriately extends the charging duration at the same time. It was originally expected to be fully charged in 1 hour, but now it may be extended to 1.5 hours to ensure the safety of the charging process and the health of the battery.

[0084] Or when it is detected that the power conversion device 300 is an AC power supply and the output power is relatively large, being "100W", the main control module 220 may preferentially choose to use the AC power supply for charging and appropriately increase the charging speed. By adjusting the parameters in the charging protocol, the charging speed is increased by 20%. For the terminal device 200 that originally took 2 hours to be fully charged, it may now be fully charged in 1.6 hours, greatly improving the charging efficiency.

[0085] Through the description of the above detailed embodiments, through the collaborative work of various interfaces, control modules, charge and discharge modules, and switch modules between the charging device and the terminal device, the terminal device realizes the comprehensive acquisition, intuitive presentation, and intelligent charging management of the charging power supply information. The tight connection relationship, clear functional relationship, and efficient data interaction relationship between different modules ensure the stability, safety, and efficiency of the entire charging process, providing users with a high-quality charging experience, protecting the health of the battery of the terminal device, and extending the service life of the battery.

Although the present application has been disclosed above with the preferred embodiments, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present application.
