[0051] Combine the following Figures 1 to 9 A connection line, a charging control method, a charging control device, and an electronic device according to embodiments of the present application are described.

[0052] In some embodiments of the present application, a connecting line is provided. Figure 1 A circuit diagram of a connecting line according to an embodiment of the present application is shown. Figure 1 As shown, the connecting lines include:

[0053] A first connector 100 is used to connect a power supply device and a terminal, and a first Vbus contact 102 and a first SBU contact 104 are provided in the first connector 100;

[0054] A second connector 200 is used to connect the power supply device and the other terminal, and a second Vbus contact 202 and a second SBU contact 204 are provided in the second connector 200;

[0055] A wiring harness 300, wherein a first end of the wiring harness 300 is connected to a first connector 100, a second end of the wiring harness 300 is connected to a second connector 200, and the wiring harness 300 comprises a first wire core 302, wherein the first wire core 302 is connected to a first Vbus contact 102 and a second Vbus contact 202 to transmit electrical energy between the first Vbus contact 102 and the second Vbus contact 202;

[0056] A first resistive element 400, wherein a first end of the first resistive element 400 is connected to the first SBU contact 104, and a second end of the first resistive element 400 is grounded;

[0057] The second resistive element 500 has a first end connected to the second SBU contact 204 and a second end connected to the ground.

[0058] In the embodiment of the present application, the first connector 100 and the second connector 200 can be set as Type-C connectors, and the wiring harness 300 of the connecting line includes a first wire core 302, and the first wire core 302 is specifically Figure 1 The Vbus line core in the circuit shown is used to transmit electric energy between the power supply device travel charger and a terminal such as a mobile phone, that is, to transmit a charging signal.

[0059] A first SBU contact 104 and a second SBU contact 204 are respectively provided in the first connector 100 and the second connector 200, a first resistive element 400 is connected to the first SBU contact 104, and a second resistive element 500 is connected to the second SBU contact 204. Figure 1 As shown, the first SBU contact 104 and the second SBU contact 204 are SBU (SBU1, SBU2) contacts in the figure, and the first resistive element 400 and the second resistive element 500 are respectively used to prompt the travel charger and the terminal that the current connection line supports "high power" charging.

[0060] Among them, both the first connector 100 and the second connector 200 can be connected to the charging device and the terminal. It can be understood that when the first connector 100 is connected to the charging device, the second connector 200 should be connected to the terminal to charge the terminal. When the first connector 100 is connected to the terminal, the second connector 200 can be connected to the charging device for charging, or it can be connected to the terminal, such as a mobile phone, a power bank, a human-computer interaction device, etc., so as to realize charging or transmit data instructions. It should be noted that if the first connector 100 and the second connector 200 are both connected to the charging device, the charging device and the connecting line will not work at this time.

[0061] Specifically, the first end of the first resistive element 400 is connected to the first SBU contact 104, and the second end of the first resistive element 400 is grounded. Therefore, when the first connector 100 is inserted into the interface, the interface can identify that a pull-down resistor is connected to the first SBU contact 104 through the contact in contact with the first SBU contact 104, thereby determining that the current connection line is a connection line that supports high-power charging. Similarly, the second resistive element 500 set in the second connector 200 can enable the terminal to identify that the current connection line is a connection line that supports high-power charging.

[0062] Furthermore, the resistance values ​​of the first resistive element 400 and the second resistive element 500 can be set accordingly according to the maximum charging power that the connecting line can support. For example, if the resistance values ​​of the first resistive element 400 and the second resistive element 500 are set to aΩ, it means that the maximum charging power that the connecting line can carry is bW, and if the resistance values ​​of the first resistive element 400 and the second resistive element 500 are set to cΩ, it means that the maximum charging power that the connecting line can carry is dW.

[0063] When the power supply device detects that the connection line is plugged in, it first determines whether a resistive element is set on the first SBU contact or the second SBU contact. If so, it further obtains the resistance value of the resistive element and determines the maximum carrying power of the connection line based on the resistance value, thereby setting the target charging power. Similarly, the terminal side sets the target power according to the same logic to establish a charging connection with the power supply device.

[0064] When the first connector is inserted into the first interface of the power supply device, the power supply device determines whether the current connection line supports fast charging by detecting whether there is a pull-down resistor on the first SBU contact (that is, detecting whether there is a first resistive element). If the power supply device detects the presence of a pull-down resistor on the first SBU contact, the power supply device confirms that the current connection line can carry a high-power charging current / voltage. If the power supply device does not detect the presence of a pull-down resistor on the first SBU contact, it confirms that the connection line is an ordinary connection line, and the charging power can be determined in accordance with the PD protocol.

[0065] Similarly, when the second connector 200 is inserted into the second interface of the terminal, the terminal adjusts its own maximum charging power by detecting whether there is a pull-down resistor on the second SBU contact 204 in the same manner.

[0066] The embodiment of the present application sets additional contacts and resistive elements in the connector of the connecting cable, so that the power supply device (such as a travel charger) and the terminal (such as a mobile phone) can identify whether the connecting cable supports high-power charging. Therefore, the power supply device and the terminal device can be quickly charged by exceeding the power limit of the protocol specification (such as the 100W display specified by the PD protocol), thereby improving the charging power and charging efficiency.

[0067] In some embodiments of the present application, Figure 1 As shown, a first CC contact 106 is also provided in the first connector 100, a second CC contact 206 is also provided in the second connector 200, and the wiring harness 300 also includes a second wire core 304, which connects the first CC contact 106 and the second CC contact 206; the connecting line also includes: a register chip 600 for storing wire material information of the connecting line, and the register chip 600 includes a data pin 602, which is connected to the second wire core 304.

[0068] In an embodiment of the present application, the connecting line is provided with a register chip 600 (E-mark), wherein the register chip 600 is used to store the wire information of the current connecting line, including the maximum current and maximum voltage that the connecting line can carry, the wire resistance, wire model, wire manufacturer identification, etc.

[0069] The second core 304 is Figure 1 The CC core shown is an AC charging confirmation signal line, which is used to enable the power supply device to detect whether there is a terminal connected. The core is mainly used to transmit data signals and is respectively connected to the first CC contact 106 in the first connector 100 and the second CC contact 206 in the second connector 200. At the same time, the signal pin of the register chip 600 is also connected to the second core 304, so that the wire information stored therein is sent to the power supply device or the terminal.

[0070] Specifically, when the connecting line is connected to the power supply device and the terminal, the power supply device detects that there is a pull-down resistor on the second core 304, that is, the CC core, which means that the terminal is connected. At this time, the wire information of the connecting line is obtained from the storage chip 600 through the second core 304, and after confirming the wire information, the wire information is sent to the terminal side through the second core 304.

[0071] At the same time, the power supply device and the terminal respectively detect whether there is a pull-down resistor on the first SBU contact 104 and the second SBU contact 204. If a pull-down resistor is detected, the power supply device and the terminal send corresponding information through the second core 304, and adjust the charging power and the power extraction power according to the resistance value of the pull-down resistor to achieve high-power charging. If the pull-down resistor on the first SBU contact 104 or the second SBU contact 204 is not detected, the power supply device sends a PD communication protocol to the terminal through the second core 304, sets the charging power and the power extraction power according to the content of the PD communication protocol, and starts charging.

[0072] The embodiment of the present application can further improve the compatibility of the connecting wires by providing a register chip 600 to store wire information.

[0073] In some embodiments of the present application, Figure 1 As shown, the first connector 100 is further provided with a first VCON contact 108, the second connector 200 is further provided with a second VCON contact 208, and the wiring harness 300 further includes a third wire core 306 and a fourth wire core 308;

[0074] The register chip 600 further includes a first power supply pin 604 and a second power supply pin 606 , wherein the first power supply pin 604 is connected to the third wire core 306 , and the second power supply pin 606 is connected to the fourth wire core 308 ;

[0075] The connection line also includes:

[0076] A first decoupling capacitor 702, wherein a first end of the first decoupling capacitor 702 is connected to the fourth line core 308, and a second end of the first decoupling capacitor 702 is grounded;

[0077] A second decoupling capacitor 704 , wherein a first end of the second decoupling capacitor 704 is connected to the third line core 306 , and a second end of the second decoupling capacitor 704 is grounded.

[0078] In the embodiment of the present application, the wiring harness 300 of the connecting line also includes a third wire core 306 and a fourth wire core 308, wherein the third wire core 306 and the fourth wire core 308 are VCONN wire cores for supplying power to the register chip 600 (E-mark). Specifically, two power supply pins are provided on the register chip 600, which are respectively connected to the third wire core 306 and the fourth wire core 308, and the third wire core 306 and the fourth wire core 308 are respectively connected to the power supply pins of the register chip 600 and the power supply contacts on the first connector 100 / the second connector 200, that is, the first VCON contact 108 and the second VCON contact 208.

[0079] Therefore, no matter which of the first connector 100 and the second connector 200 is connected to the terminal or the power supply device, the corresponding wire core can be used to power the storage chip 600, thereby obtaining the wire information stored in the storage chip 600, thereby improving the user experience of the connecting line.

[0080] Furthermore, the connecting line also includes a first decoupling capacitor 702 and a second decoupling capacitor 704, wherein the fourth core 308 is grounded through the first decoupling capacitor 702, and the third core 306 is grounded through the second decoupling capacitor 704. The first decoupling capacitor 702 and the second decoupling capacitor 704 can ensure the voltage and current stability of the power supply signals on the third core 306 and the fourth core 308, thereby ensuring the power supply stability of the register chip 600 and improving the reliability of the connecting line.

[0081] In some embodiments of the present application, Figure 1 As shown, the number of the first SBU contacts 104 is two, and the two first SBU contacts 104 are arranged opposite to each other; the number of the second SBU contacts 204 is two, and the two second SBU contacts 204 are arranged opposite to each other;

[0082] The first resistive element 400 includes a first resistor 402 and a second resistor 404, and the first resistor 402 and the second resistor 404 are respectively connected to one of the two first SBU contacts 104; the second resistive element 500 includes a third resistor 502 and a fourth resistor 504, and the third resistor 502 and the fourth resistor 504 are respectively connected to one of the two second SBU contacts 204;

[0083] The resistance values ​​of the first resistor 402 , the second resistor 404 , the third resistor 502 and the fourth resistor 504 are equal.

[0084] In the embodiment of the present application, the number of the first SBU contact 104 and the second SBU contact 204 are both two, and the corresponding contacts are arranged relatively. Specifically, the first connector 100 and the second connector 200 are connected to the Type-C type, and the characteristic of this type of connector is that there is no need to distinguish the insertion direction of the connector when it is inserted into the interface. Therefore, contacts and corresponding pull-down resistors are set at symmetrical positions on both sides of the Typc C connector, that is, the first resistor 402, the second resistor 404, the third resistor 502 and the fourth resistor 504 mentioned above, so that no matter in what direction the connecting line is inserted into the interface, the corresponding contacts and pull-down resistors can always be recognized by the power supply device and the terminal, which improves the convenience of using the wire.

[0085] At the same time, the resistance values ​​of the first resistor 402, the second resistor 404, the third resistor 502 and the fourth resistor 504 are equal, so that the resistance values ​​of the pull-down resistors obtained by the power supply device and the terminal are the same, that is, the heavy-load power that the identified wires can carry is the same, ensuring charging reliability.

[0086] In some embodiments of the present application, a charging control method is provided for controlling a power supply device, the power supply device comprising a first interface, Figure 2 FIG. 1 shows one of the flow charts of the charging control method according to an embodiment of the present application. Figure 2 As shown, the method includes:

[0087] Step 802, when it is identified that the first interface is connected to the connection line, detecting a first resistive element or a second resistive element of the connection line;

[0088] In step 802, the connection line is specifically a connection line provided in any of the above embodiments.

[0089] Step 804, when the first resistive element or the second resistive element is detected, determining the first power according to the resistance value of the first resistive element or the second resistive element;

[0090] Step 806: output a power supply signal to the first wire core of the connecting wire according to the first power.

[0091] In the embodiment of the present application, corresponding contacts and resistive elements are provided in the connector of the connecting line. When the resistive element is detected, it indicates that the current connecting line is a connecting line that supports high-power charging. Furthermore, the maximum carrying power of the charging line is determined based on the resistance value of the resistive element, and the first power when charging the terminal is determined based on the maximum carrying power. Based on the first power, a power supply signal is output to the terminal through the first core in the wiring harness of the connecting line, that is, the Vbus core, for charging and power use of the terminal.

[0092] Specifically, for example, setting the resistance of the first resistive element and the second resistive element to aΩ means that the maximum charging power that the connecting line can carry is bW, and setting the resistance of the first resistive element and the second resistive element to cΩ means that the maximum charging power that the connecting line can carry is dW. After determining the maximum charging power that the connecting line can carry, select the appropriate charging power to charge the terminal. This allows the power supply device (such as a travel charger) and the terminal (such as a mobile phone) to identify whether the connecting line supports high-power charging, so that the power supply device and the terminal device can be quickly charged by exceeding the power limit specified by the protocol (such as the 100W display specified by the PD protocol), thereby improving the charging power and charging efficiency.

[0093] In some embodiments of the present application, when no resistive element is detected, a confirmation signal of the second core of the connecting line is obtained; when the confirmation signal is obtained, a protocol charging signal is sent to the terminal through the second core; the second power is determined according to the protocol charging signal, and a power supply signal is output to the first core of the connecting line according to the second power; wherein the second power is lower than the first power.

[0094] In an embodiment of the present application, if the power supply device does not detect that the corresponding contacts and resistive elements are provided in the connector of the connecting line, that is, when the pull-down resistor is not detected, a confirmation signal is further obtained through the second core connected first. Among them, the second core is specifically the CC core, that is, the AC charging confirmation signal line. If there is a confirmation signal on the second core, that is, the presence of a pull-down resistor is detected on the CC core, it means that the terminal device has been inserted. At this time, according to the PD communication information, a communication is sent to the terminal, and the corresponding second power and the PD protocol are determined according to the communication information. The power supply signal is input to the first core of the connecting line according to the second power, that is, the power supply signal is output to Vbus, so that the terminal obtains electrical energy through the power supply signal on Vbus.

[0095] Among them, since the maximum charging power stipulated by the PD protocol is 100W, the charging power at this time is generally less than or equal to 100W, and is also less than the charging power during "high power" charging, that is, the first power mentioned above.

[0096] Among them, for power supply equipment, Figure 3 The following is a flowchart of the working process of the power supply device according to the embodiment of the present application. Figure 3 As shown, including:

[0097] Step 902, detecting that a connecting line is inserted;

[0098] Step 904, determine whether there is resistance on the SBU contact; if yes, proceed to step 908, otherwise proceed to step 906;

[0099] Step 906, determine whether there is resistance on the CC core; if yes, proceed to step 910, otherwise proceed to step 912;

[0100] Step 908, determining the charging power according to the resistance value of the SBU;

[0101] Step 910, performing PD communication on CC;

[0102] Step 912, Vbus does not output power;

[0103] Step 914: Vbus outputs the corresponding power.

[0104] In some embodiments of the present application, a charging control method is provided for a terminal. Figure 4 FIG. 2 shows a second flow chart of a charging control method according to an embodiment of the present application. Figure 4 As shown, the method includes:

[0105] Step 1002, when it is identified that the second interface is connected to the connecting line, detecting a power supply signal of a first core of the connecting line;

[0106] In step 1002, the connecting line is the connecting line provided in any of the above embodiments.

[0107] Step 1004, when the power supply signal is detected, detecting the first resistive element or the second resistive element of the connecting line;

[0108] Step 1006, when the first resistive element or the second resistive element is detected, determining the first power according to the resistance value of the first resistive element or the second resistive element;

[0109] Step 1008: charging at a first power via a power supply signal.

[0110] In the embodiment of the present application, firstly, it is detected whether there is a charging signal on the first core of the connecting line, that is, VBus. If there is, it means that the other end of the connecting line is connected to a power supply device, and at this time, the power supply power is further determined.

[0111] Specifically, the connector of the connection line is provided with corresponding contacts and resistive elements. When the resistive element is detected, it indicates that the current connection line is a connection line that supports high-power charging. Furthermore, the maximum carrying power of the charging line is determined according to the resistance value of the resistive element. According to the maximum carrying power, the terminal sets its own power supply and obtains the power supply signal output by the power supply device through the first core of the connection line, that is, the Vbus core.

[0112] For example, setting the resistance of the first resistive element and the second resistive element to aΩ means that the maximum charging power that the connecting line can carry is bW, and setting the resistance of the first resistive element and the second resistive element to cΩ means that the maximum charging power that the connecting line can carry is dW. After determining the maximum charging power that the connecting line can carry, the appropriate power is selected for charging.

[0113] In the embodiment of the present application, the power supply device (such as a travel charger) and the terminal (such as a mobile phone) can identify whether the connection line supports high-power charging by setting a pull-down resistor in the SBU, so that the power supply device and the terminal device can be fast charged by exceeding the power upper limit of the protocol specification (such as the 100W display specified by the PD protocol), thereby improving the charging power and charging efficiency. At the same time, by detecting the pull-down resistor to determine the charging power, the PD communication process is skipped, which can reduce the time to enter high-power fast charging and improve charging efficiency.

[0114] In some embodiments of the present application, when no resistive element is detected, a protocol charging signal is obtained through the second core of the connecting line; when the protocol charging signal is obtained, the corresponding second power is determined according to the protocol charging signal; charging is performed at the second power through the power supply signal; when the protocol charging signal is not obtained, charging is performed at a third power through the power supply signal; wherein the second power is lower than the first power, and the third power is lower than the second power.

[0115] In an embodiment of the present application, if no pull-down resistor is detected on the SBU, it means that the current connection line does not support high-power charging. At this time, PD protocol communication is performed with the power supply device through the second core of the connection line, that is, the CC core, specifically receiving the protocol charging signal sent by the power supply device. The protocol charging signal is used to determine the maximum charging power of the terminal during charging, and the power that the power supply device can provide.

[0116] When the protocol charging signal on the CC is obtained, the corresponding second power is determined according to the PD protocol, and charging is performed using the second power.

[0117] If the CC protocol charging signal cannot be obtained, it is determined that the CC core may be faulty. In order to ensure charging safety and enable the terminal to charge normally, the terminal charges at the third power. Since the maximum charging power specified by the PD protocol is 100W, the charging power at this time is generally less than or equal to 100W, and is also less than the charging power during "high power" charging, that is, the first power mentioned above.

[0118] When the charging power cannot be set through the PD protocol, the terminal is charged at a safe power that can meet the terminal activities, that is, the third power.

[0119] The embodiment of the present application configures the terminal to charge at a safe third power when the CC core of the terminal is abnormal, so that the terminal can still be charged when the CC core of the connecting line is abnormal, thereby improving the versatility of charging.

[0120] Figure 5 The working flow diagram of the terminal according to the embodiment of the present application is shown as follows: Figure 5 As shown, including:

[0121] Step 1102, detecting that a connecting line is inserted;

[0122] Step 1104, determine whether there is voltage on Vbus; if yes, proceed to step 1106, otherwise repeat step 1104;

[0123] Step 1106, determine whether there is a resistor on the SBU; if yes, proceed to step 1110, otherwise proceed to step 1108;

[0124] Step 1108, determine whether there is voltage on CC; if yes, proceed to step 1114, otherwise proceed to step 1116;

[0125] Step 1110, determining the charging power according to the resistance value of the SBU resistor;

[0126] Step 1112, notifying the travel charger to adjust the power supply;

[0127] Step 1114, notifying the travel charger of output power via PD communication;

[0128] Step 1116, notifying the travel charger of output power according to a preset method.

[0129] In some embodiments of the present application, a charging control device is provided for a power supply device, wherein the power supply device includes a first interface, Figure 6 FIG. 1 shows one of the structural block diagrams of the charging control device according to an embodiment of the present application. Figure 6 As shown, the charging control device 1200 includes:

[0130] A first identification module 1202 is used to detect a first resistive element of the connection line when identifying that the first interface is connected to the connection line;

[0131] A first determining module 1204 is configured to determine a first power according to a resistance value of the first resistive element when the first resistive element is detected;

[0132] The output module 1206 is used to output the first power to the first core of the connecting line.

[0133] In the embodiment of the present application, corresponding contacts and resistive elements are provided in the connector of the connecting line. When the resistive element is detected, it indicates that the current connecting line is a connecting line that supports high-power charging. Furthermore, the maximum carrying power of the charging line is determined based on the resistance value of the resistive element, and the first power when charging the terminal is determined based on the maximum carrying power. Based on the first power, a power supply signal is output to the terminal through the first core in the wiring harness of the connecting line, that is, the Vbus core, for charging and power use of the terminal.

[0134] Specifically, for example, setting the resistance of the first resistive element and the second resistive element to aΩ means that the maximum charging power that the connecting line can carry is bW, and setting the resistance of the first resistive element and the second resistive element to cΩ means that the maximum charging power that the connecting line can carry is dW. After determining the maximum charging power that the connecting line can carry, select the appropriate charging power to charge the terminal. This allows the power supply device (such as a travel charger) and the terminal (such as a mobile phone) to identify whether the connecting line supports high-power charging, so that the power supply device and the terminal device can be quickly charged by exceeding the power limit specified by the protocol (such as the 100W display specified by the PD protocol), thereby improving the charging power and charging efficiency.

[0135] In some embodiments of the present application, the first identification module 1202 is further configured to obtain a confirmation signal of the second core of the connecting line when the resistive element is not detected;

[0136] The output module 1206 is also used to send a protocol charging signal to the terminal through the second core when the confirmation signal is obtained; determine the second power according to the protocol charging signal, and output a power supply signal to the first core of the connecting line according to the second power;

[0137] The second power is lower than the first power.

[0138] In an embodiment of the present application, if the power supply device does not detect that the corresponding contacts and resistive elements are provided in the connector of the connecting line, that is, when the pull-down resistor is not detected, a confirmation signal is further obtained through the second core connected first. Among them, the second core is specifically the CC core, that is, the AC charging confirmation signal line. If there is a confirmation signal on the second core, that is, the presence of a pull-down resistor is detected on the CC core, it means that the terminal device has been inserted. At this time, according to the PD communication information, a communication is sent to the terminal, and the corresponding second power and the PD protocol are determined according to the communication information. The power supply signal is input to the first core of the connecting line according to the second power, that is, the power supply signal is output to Vbus, so that the terminal obtains electrical energy through the power supply signal on Vbus.

[0139] Among them, since the maximum charging power stipulated by the PD protocol is 100W, the charging power at this time is generally less than or equal to 100W, and is also less than the charging power during "high power" charging, that is, the first power mentioned above.

[0140] In some embodiments of the present application, a charging control device is provided for a terminal, wherein the terminal includes a second interface. Figure 7 The second structural block diagram of the charging control device according to the embodiment of the present application is shown as follows: Figure 7 As shown, the charging control device 1300 includes:

[0141] The second identification module 1302 is used to detect the power supply signal of the first core of the connecting line when it is identified that the second interface is connected to the connecting line; and detect the second resistive element of the connecting line when the power supply signal is detected;

[0142] A second determining module 1304 is configured to determine the first power according to the resistance value of the second resistive element when the second resistive element is detected;

[0143] The charging module 1306 is configured to charge with a first power through a power supply signal.

[0144] In the embodiment of the present application, firstly, it is detected whether there is a charging signal on the first core of the connecting line, that is, VBus. If there is, it means that the other end of the connecting line is connected to a power supply device, and at this time, the power supply power is further determined.

[0145] Specifically, the connector of the connection line is provided with corresponding contacts and resistive elements. When the resistive element is detected, it indicates that the current connection line is a connection line that supports high-power charging. Furthermore, the maximum carrying power of the charging line is determined according to the resistance value of the resistive element. According to the maximum carrying power, the terminal sets its own power supply and obtains the power supply signal output by the power supply device through the first core of the connection line, that is, the Vbus core.

[0146] For example, setting the resistance of the first resistive element and the second resistive element to aΩ means that the maximum charging power that the connecting line can carry is bW, and setting the resistance of the first resistive element and the second resistive element to cΩ means that the maximum charging power that the connecting line can carry is dW. After determining the maximum charging power that the connecting line can carry, the appropriate power is selected for charging.

[0147] In the embodiment of the present application, the power supply device (such as a travel charger) and the terminal (such as a mobile phone) can identify whether the connection line supports high-power charging by setting a pull-down resistor in the SBU, so that the power supply device and the terminal device can be fast charged by exceeding the power upper limit of the protocol specification (such as the 100W display specified by the PD protocol), thereby improving the charging power and charging efficiency. At the same time, by detecting the pull-down resistor to determine the charging power, the PD communication process is skipped, which can reduce the time to enter high-power fast charging and improve charging efficiency.

[0148] In some embodiments of the present application, the second identification module 1302 is further used to obtain a protocol charging signal through a second wire core of the connecting wire when no resistive element is detected;

[0149] The second determination module 1304 is further configured to determine the corresponding second power according to the protocol charging signal when the protocol charging signal is acquired;

[0150] The charging module 1306 is further configured to charge at a second power through a power supply signal; and charge at a third power through a power supply signal when no protocol charging signal is obtained;

[0151] The second power is lower than the first power, and the third power is lower than the second power.

[0152] In an embodiment of the present application, if no pull-down resistor is detected on the SBU, it means that the current connection line does not support high-power charging. At this time, PD protocol communication is performed with the power supply device through the second core of the connection line, that is, the CC core, specifically receiving the protocol charging signal sent by the power supply device. The protocol charging signal is used to determine the maximum charging power of the terminal during charging, and the power that the power supply device can provide.

[0153] When the protocol charging signal on the CC is obtained, the corresponding second power is determined according to the PD protocol, and charging is performed using the second power.

[0154] If the CC protocol charging signal cannot be obtained, it is determined that the CC core may be faulty. In order to ensure charging safety and enable the terminal to charge normally, the terminal charges at the third power. Since the maximum charging power specified by the PD protocol is 100W, the charging power at this time is generally less than or equal to 100W, and is also less than the charging power during "high power" charging, that is, the first power mentioned above.

[0155] When the charging power cannot be set through the PD protocol, the terminal is charged at a safe power that can meet the terminal activity, that is, the third power (generally 5W, 5V / 1A).

[0156] The embodiment of the present application configures the terminal to charge at a safe third power when the CC core of the terminal is abnormal, so that the terminal can still be charged when the CC core of the connecting line is abnormal, thereby improving the versatility of charging.
