[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] The terms "first" and "second" in the specification and claims of this application may explicitly or implicitly include one or more of the features. In the description of this invention, unless otherwise stated, "a plurality of" means two or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0051] like Figure 1 As shown, this application provides an electronic device, including:

[0052] The first interface 1 is used to connect to the second interface of the charging device;

[0053] Battery 2 is connected to the first interface 1;

[0054] Sending module 3 is connected to the first interface 1;

[0055] The processor 4, connected to the battery 2 and the transmitting module 3, is used to detect the state of the battery 2 and / or send a charging request message to the charging device through the transmitting module 3.

[0056] In this embodiment, the first interface 1 can be a charging interface of an electronic device, used to connect to a second interface of the charging device. When the first interface 1 is connected to the second interface, the charging device charges the electronic device. The battery 2 is connected to the first interface 1, and the charging device charges the battery 2 of the electronic device through the first interface 1 and the second interface.

[0057] The first interface 1 can also be used to transmit information with the charging device. The sending module 3 is used to send information to the charging device. The sending module 3 is connected to the first interface 1 and transmits information to the second interface of the charging device through the first interface 1. The charging device can be a charging adapter.

[0058] The processor 4 is connected to the battery 2 and can obtain the battery power status of the battery 2, thereby determining the charging timing, charging status, etc. For example, when the charging device is charging the electronic device, if the battery power of the battery 2 reaches the maximum allowable value, that is, the battery is fully charged, it can send a stop charging information to the charging device; and / or, the processor 4 can detect the status of the battery 2 to determine the voltage, current, etc. that need to be charged, and then send a corresponding charging request message to the charging device.

[0059] The processor 4 is also connected to the sending module 3. When the processor 4 sends information to the charging device, it needs to send the information to the sending module 3, which will then convert the information and send it to the charging device through the first interface 1.

[0060] Optionally, the transmitting module 3 can perform signal modulation and conversion on the input information, for example, modulating the input information to a mode suitable for DC communication before transmitting it. The second interface of the charging device receives the information and transmits it to the receiving module, which demodulates the information to obtain information that the control module of the charging device can recognize, and then transmits the demodulated information to the control module. The control module can adjust the voltage and / or current output to the electronic device according to the parsed information. The control module is located on the charging device side, and the control module can be a charging control chip. That is, by placing the charging control chip on the charging device side instead of in the electronic device (such as a terminal), the overheating of the electronic device can be effectively reduced or even avoided.

[0061] In the embodiments of this application, the electronic device can complete the charging process without the need for a charging management chip, which can avoid the heat generated by the charging management chip, solve the heat generation problem during the charging process of the electronic device, and save device costs and internal space of the electronic device.

[0062] As an optional embodiment, the transmitting module 3 includes: a modulation circuit 31 and a first capacitor 32; wherein, the input terminal of the modulation circuit 31 is connected to the processor 4, the output terminal of the modulation circuit 31 is connected to the first capacitor 32, and the first capacitor 32 is connected to the first interface 1; the modulation circuit 31 is used to perform DC-DC conversion on the input charging request message.

[0063] In this embodiment, such as Figure 2As shown, the transmitting module 3 includes a modulation circuit 31 and a first capacitor 32 for DC-DC conversion of the input information. Optionally, the modulation circuit 31 can be a 2 Amplitude Shift Keying (2ASK) modulation circuit, a Frequency Shift Keying (FSK) modulation circuit, a frequency modulation circuit, or an amplitude modulation circuit. Optionally, the processor 4 includes a Universal Asynchronous Receiver / Transmitter (UART) interface, or a General Purpose I / O Port (GPIO). The charging request message generated by the processor 4 is sent to the 2ASK modulation circuit through the UART interface. The 2ASK modulation circuit converts the charging request message into a signal suitable for transmission on a DC line, couples it to the first interface 1 through the first capacitor 32, and the first interface 1 sends the modulated charging request message to the charging device. The receiving module of the charging device includes a demodulation circuit. After demodulating the charging request message, the demodulation circuit sends it to the control module of the charging device. The control module then controls and adjusts the output voltage and / or current to charge the electronic device.

[0064] The modulation circuit 31 in this embodiment can include various circuit forms, as long as it can realize the DC-DC conversion of information. Examples are given below.

[0065] As an optional embodiment, the modulation circuit 31 includes: a logic control unit 311;

[0066] The input terminal of the logic control unit 311 is connected to the processor 4, and the input terminal of the logic control unit 311 receives the charging request message and the clock signal; the output terminal of the logic control unit 311 is connected to the first capacitor 32, and the output terminal of the logic control unit 311 outputs the DC-DC conversion signal of the charging request message.

[0067] Optionally, the logic control unit 311 can be a logic AND gate, which modulates the charging request message and clock signal of the processor 4 together into a 2ASK signal suitable for DC transmission. Taking the logic control unit 311 as an example of a logic AND gate, such as... Figure 3As shown, the processor 4 outputs a charging request and a clock signal through the UART interface; the logic AND gate modulates the charging request and the clock signal to obtain a 2ASK signal that can be transmitted in DC; the converted signal is coupled to the first interface 1 through the first capacitor 32 and transmitted to the charging device through the first interface 1.

[0068] As another optional embodiment, such as Figure 4 As shown, the modulation circuit 31 includes:

[0069] A first resistor 312, the first end of the first resistor 312 is connected to the processor 4, and the first end of the first resistor 312 receives the charging request message;

[0070] The second resistor 313 has a first end connected to the processor 4, and the first end of the second resistor 313 receives the charging request message.

[0071] The second capacitor 314 has its first end connected to the processor 4, and a clock signal is input to the first end of the second capacitor 314.

[0072] The third resistor 315 has its first end connected to the second end of the second capacitor 314, and its second end is grounded.

[0073] The first transistor 316 has its first terminal connected to the second terminal of the second capacitor 314, the second terminal of the second resistor 313, and the first terminal of the third resistor 315; the second terminal of the first transistor 316 is connected to the second terminal of the first resistor 312, and outputs a DC-DC conversion signal of the charging request message to the first capacitor 32 at the connection point; the third terminal of the first transistor 316 is grounded.

[0074] In this embodiment, the clock signal output by the processor 4 is connected to the second capacitor 314, and the UART interface of the processor 4 is connected to the first end of the first resistor 312 and the first end of the second resistor 313. Then, the charging request output through the UART interface is transmitted to the first resistor 312 and the second resistor 313.

[0075] The first terminal of the first transistor 316 is connected to the second terminal of the second resistor 313 and the first terminal of the third resistor 315, respectively. The second terminal of the first transistor 316 is connected to the second terminal of the first resistor 312, and the third terminal of the first transistor 316 is grounded. The first transistor 316 is controlled by the high and low levels of the UART, causing the second terminal of the first transistor 316 to output a modulated 2ASK signal. This signal is coupled to the first interface 1 through the first capacitor 32, and the first interface 1 transmits the modulated charging request to the charging device.

[0076] In this embodiment, the modulation circuit 31 can be a 2ASK modulation circuit. The 2ASK modulation circuit transmits the charging request message from the processor 4 of the electronic device to the demodulation circuit on the charging device side. The demodulation circuit can be a 2ASK demodulation circuit, and the message is transmitted to the control module on the charging device side. The control module then adjusts the output voltage and / or output current of the charging device. Optionally, the electronic device and the charging device exchange information via two lines, VBUS and GND, i.e., the information to be transmitted (such as the charging request message) is loaded onto VBUS for transmission. For example... Figure 2 As shown, the first interface 1 on the electronic device side is connected to the second interface on the charging device side through VBUS and GND to realize the transmission of information and simplify the cable design for transmitting information.

[0077] In this embodiment, the processor's charging request message is transmitted to the charging device via a DC charging cable (such as VBUS and GND) through DC modulation. The demodulation module of the charging device outputs a demodulated signal, and the control module of the charging device parses the charging request message and controls the voltage regulation module to output a suitable voltage and / or the current regulation module to output a suitable current by outputting a PWM signal. Therefore, this embodiment eliminates the need for a charging control chip on the electronic device side, thus solving the overheating problem caused by the charging management chip on the electronic device side. Furthermore, the charging cable does not require an additional communication control cable, further reducing the overall implementation cost of the charging solution. This embodiment can be used in mobile devices such as mobile phones, headphones, and watches.

[0078] In the embodiments of this application, the electronic device can complete the charging process without the need for a charging management chip, which can avoid the heat generated by the charging management chip, solve the heat generation problem during the charging process of the electronic device, and save device costs and internal space of the electronic device.

[0079] like Figure 1 As shown in the illustration, this application also provides a charging device, including:

[0080] The second interface 5 is used to connect to the first interface of the electronic device;

[0081] The receiving module 6 is connected to the second interface 5;

[0082] The current regulation module 7 is connected to the second interface 5;

[0083] Voltage regulation module 8 is connected to current regulation module 7;

[0084] The control module 9 is connected to the receiving module 6, the current regulation module 7, and the voltage regulation module 8 respectively. The control module 9 is used to receive the charging request message sent by the electronic device through the receiving module 6, and control the current regulation module 7 to adjust the output current according to the charging request message, and / or control the voltage regulation module 8 to adjust the output voltage according to the charging request message.

[0085] In this embodiment, the charging device is, for example, a charging adapter. The second interface 5 can be used to output electrical energy to the electronic device and can also be used to receive information transmitted by the electronic device. The receiving module 6 is used to receive information sent by the electronic device, such as receiving a charging request message sent by the electronic device. The receiving module 6 can convert the received information to obtain information that the control module 9 can recognize. For example, if the receiving module 6 receives a charging request message transmitted by the second interface 5, and this charging request message is a message suitable for DC communication after being modulated by the electronic device, then the receiving module 6 demodulates the charging request message to obtain information content that the control module 9 can recognize, and transmits it to the control module.

[0086] The control module 9 is connected to the current regulation module 7 and the voltage regulation module 8. It can determine the required power, voltage, and current of the electronic device based on the parsed charging request message, thereby controlling the current regulation module 7 to output a suitable current and / or controlling the voltage regulation module to output a suitable voltage. The control module is located on the charging device side. This control module can be a charging control chip. By placing the charging control chip on the charging device side, rather than within the electronic device, the overheating of the electronic device can be effectively reduced or even avoided.

[0087] In embodiments of this application, a control module is provided within the charging device. This control module controls the current regulation module to output a suitable current and / or controls the voltage regulation module to output a suitable voltage based on the charging request message from the electronic device. Since the control module for regulating voltage and / or current is located within the charging device, the voltage and / or current conversion is completed within the charging device. This avoids overheating of the electronic device caused by the charging management chip, and also saves on the component costs and internal space of the electronic device.

[0088] As an optional embodiment, the receiving module 6 includes:

[0089] Demodulation circuit 61 and third capacitor 62;

[0090] One end of the third capacitor 62 is connected to the second interface 5, and the other end of the third capacitor 62 is connected to the input terminal of the demodulation circuit 61; the output terminal of the demodulation circuit 61 is connected to the control module 9; the demodulation circuit 61 is used to demodulate the input charging request message.

[0091] In this embodiment, such as Figure 2 As shown, the receiving module 6 includes a demodulation circuit 61 and a third capacitor 62, used to demodulate and convert the received information. Optionally, the demodulation circuit 61 can be a 2ASK demodulation circuit. For example, the transmitting module 3 of the electronic device couples a 2ASK signal (such as a modulated charging request message) to the 2ASK demodulation circuit through the first capacitor 32. The 2ASK demodulation circuit converts the 2ASK signal into a signal suitable for the control module 9 to receive, and sends it to the control module 9 through the UART interface.

[0092] Among them, such as Figure 2 As shown, the control module 9 receives the charging request message from the processor 4 of the electronic device through the UART port. The control module 9 can control the voltage regulation module 8 to output a suitable voltage by outputting a PWM signal; the control module 9 can also control the current regulation module 7 to output a suitable current by outputting a PWM signal.

[0093] As an optional embodiment, such as Figure 5 As shown, the demodulation circuit 61 includes:

[0094] The second transistor 611, the input terminal of which is connected to the third capacitor 62;

[0095] The fourth capacitor 612 has its first terminal connected to the output terminal of the second transistor 611, and its second terminal grounded.

[0096] The fourth resistor 613 has its first end connected to the output terminal of the second transistor 611, and its second end grounded.

[0097] The positive terminal of the comparator 614 is connected to the output terminal of the second transistor 611, the first terminal of the fourth resistor 613, and the first terminal of the fourth capacitor 612, respectively. The negative terminal of the input terminal of the comparator 614 is connected to the reference voltage. The output terminal of the comparator 614 is connected to the control module 9.

[0098] In this embodiment, the input terminal of the second transistor 611 is connected to the third capacitor 62; the output terminal of the second transistor 611 is connected to the first terminal of the fourth capacitor 612 and the first terminal of the fourth resistor 613, respectively, and the second terminals of the fourth capacitor 612 and the fourth resistor 613 are both grounded. The output terminal of the second transistor 611 is also connected to the comparator 614. The second transistor 611 may be a diode.

[0099] Among them, such as Figure 5 As shown, the first end of the third capacitor 62 is connected to the DC charging cable of the second interface 5, which can couple the 2ASK signal to the anode of the second transistor 611 (i.e., diode); the cathode of the second transistor 611, together with the fourth capacitor 612 and the fourth resistor 613, forms an envelope detector for the 2ASK signal, realizing the envelope output of the 2ASK signal.

[0100] The positive (+) terminal of the input of the comparator 614 is connected to the cathode of the second transistor 611, the first terminal of the fourth capacitor 612, and the first terminal of the fourth resistor 613. The negative (-) terminal of the input of the comparator 614 is connected to the reference voltage. By comparing the envelope signal output from the cathode of the second transistor 611 with the magnitude of the reference voltage, the 2ASK signal (such as the charging request message) is demodulated, and the demodulated UART signal is output to the control module 9.

[0101] In this embodiment, the modulation circuit on the charging device side can be a 2ASK modulation circuit. The 2ASK modulation circuit transmits the charging request message from the electronic device's processor to the demodulation circuit 61 on the charging device side. The demodulation circuit 61 can be a 2ASK demodulation circuit, and the message is transmitted to the control module 9. The control module 9 then adjusts the output voltage and / or output current of the charging device. Optionally, the electronic device and the charging device transmit information via two lines, VBUS and GND, meaning the information to be transmitted is loaded into VBUS for transmission. For example... Figure 2 As shown, the first interface 1 on the electronic device side is connected to the second interface 5 on the charging device side via VBUS and GND to realize the transmission of information and simplify the cable design for transmitting information.

[0102] In this embodiment, the charging request message from the processor of an electronic device is transmitted to the 2ASK demodulation module (i.e., the receiving module) via a DC charging cable using 2ASK modulation. The control module parses the charging request message from the processor through the UART signal output by the 2ASK demodulation module, and controls the voltage regulation module to output a suitable voltage and / or the current regulation module to output a suitable current by outputting a PWM signal. Therefore, this embodiment eliminates the need for a charging control chip in the electronic device, avoiding overheating issues caused by the charging management chip, and eliminates the need for an additional communication control cable, further reducing the overall cost of the charging solution. This embodiment can be used in mobile devices such as mobile phones, headphones, and watches.

[0103] The following describes the control process for charging the electronic device and the charging device described in the embodiments of this application.

[0104] like Figure 6 As shown, this application provides a charging control method applied to the above-mentioned electronic device, including:

[0105] Step 601: Obtain battery status;

[0106] Step 602: Send a charging request message to the charging device;

[0107] The charging request message includes at least one of the following: battery status, voltage requirement information, and current requirement information.

[0108] Optionally, the processor of the electronic device acquires the battery status and, based on the battery status, can determine information such as charging timing and charging status. For example, when the charging device is charging the electronic device, if the battery level reaches the maximum allowable value, i.e., the battery is fully charged, it can send a stop charging message to the charging device; and / or, the processor of the electronic device detects the battery status to determine the required voltage, current, etc., and then sends a corresponding charging request message to the charging device. The charging request message may include: the battery status of the electronic device, voltage requirements, current requirements, etc., so that the charging device can adjust the output voltage and / or current to the electronic device.

[0109] After receiving the charging request message, the charging device parses the message content and adjusts the current and / or voltage output to the electronic device accordingly. That is, during charging of the electronic device, the current and / or voltage conversion is completed within the charging device. The electronic device can complete the charging process without a dedicated charging management chip, avoiding the heat generated by such a chip, solving the heat problem during charging, and saving on component costs and internal space.

[0110] Optionally, before sending a charging request message to the charging device, the method further includes:

[0111] The charging request message is generated based on the battery status.

[0112] The charging request message is modulated to obtain the charging request message after DC conversion;

[0113] Sending a charging request message to the charging device includes:

[0114] Send the charging request message after DC conversion to the charging device.

[0115] In this embodiment, the processor of the electronic device can determine the required input voltage, current, and other parameters based on the detected battery state, thereby generating the charging request message. The modulation circuit of the electronic device performs DC-DC conversion on the charging request message, converting it into a signal suitable for transmission on a DC line, and sends it to the charging device. The charging device includes a control module for adjusting the output voltage and / or current. This control module can be a charging control chip; placing the charging control chip on the charging device side effectively prevents the electronic device from overheating. The charging device can demodulate the charging request message and control and adjust the output voltage and / or current based on the parsed information content, thereby charging the electronic device.

[0116] In the embodiments of this application, the electronic device can complete the charging process without the need for a charging management chip, which can avoid the heat generated by the charging management chip, solve the heat generation problem during the charging process of the electronic device, and save device costs and internal space of the electronic device.

[0117] like Figure 7 As shown, this application provides a charging control method applied to the above-mentioned charging device, including:

[0118] Step 701: Receive a charging request message sent by the electronic device;

[0119] Step 702: Adjust the output voltage and / or output current according to the charging request message;

[0120] The charging request message includes at least one of the following: battery status, voltage requirement information, and current requirement information.

[0121] In this embodiment, the receiving module of the charging device can receive charging request messages sent by the electronic device. These charging request messages may include the battery status, voltage requirements, and current requirements of the electronic device. The control module of the charging device can adjust the output voltage and / or current to the electronic device according to its requirements.

[0122] Optionally, adjusting the output voltage and / or output current according to the charging request message includes: parsing the charging request message to obtain the charging needs of the electronic device; and adjusting the output voltage and / or output current according to the charging needs.

[0123] In this embodiment, the charging request message received by the charging device can be a modulated message from the electronic device. The charging device can demodulate the charging request message through a demodulation circuit to obtain information content that the control module can recognize. The control module of the charging device determines the charging needs of the electronic device based on the parsed information content, and adjusts the output current through the control current adjustment module and / or adjusts the output voltage through the voltage adjustment module.

[0124] In embodiments of this application, the charging device includes a control module for adjusting the output voltage and / or current. This control module can be a charging control chip, meaning that placing the charging control chip on the charging device side effectively prevents the electronic device from overheating. Based on the charging request message from the electronic device, the charging device controls the current adjustment module to output a suitable current, and / or controls the voltage adjustment module to output a suitable voltage.
