Technical Field

Background

The USB-IF organization issues a PD charging protocol based on the CC channel in the Type-C interface, which can increase the charging power of the Type-C interface of the current default maximum power 5V/2A to 100W.

Although the Type-C interface can simultaneously support PD fast charging and non-PD fast charging, due to the difference between the communication paths, the charging device that simultaneously supports PD fast charging and non-PD fast charging outputs the requirement for the charging parameters of the charging process through the two communication paths during the charging process, thereby causing the disorder of the output voltage and current of the power supply terminal.

Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, fig. 1 is a schematic terminal structure diagram of a hardware operating environment according to an embodiment of the present invention.

The terminal of the embodiment of the invention can be a terminal with a Type-C interface, such as a PC, a tablet computer, a portable computer, a smart phone, an adapter and the like.

As shown in fig. 1, the terminal may include: a processor 1001, such as a CPU, a communication bus 1002, a Type-C interface 1003, and a memory 1005. Wherein a communication bus 1002 is used to enable connective communication between these components. The memory 1005 may be a high-speed RAM memory or a non-volatile memory (e.g., a magnetic disk memory). The memory 1005 may alternatively be a storage device separate from the processor 1001.

Those skilled in the art will appreciate that the terminal structure shown in fig. 1 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.

As shown in fig. 1, a memory 1005, which is a kind of computer storage medium, may include an operating system and a charging control program therein.

In the terminal shown in fig. 1, the processor 1001 may be configured to call a charging control program stored in the memory 1005 and perform the operations of the following embodiments of the charging control method.

Based on the terminal, various embodiments of the charging control method in the present application are proposed.

Referring to fig. 2, in a first embodiment of the charging control method of the present invention, the charging control method is applied to a terminal to be charged, and the method includes the steps of:

step S10, after detecting that the voltage value of a VBUS pin of a charging cable connected to the terminal to be charged reaches a preset voltage value, acquiring the battery state of the terminal to be charged;

in the scheme, the terminal to be charged is a terminal with a Type-C interface, and can be a mobile phone, a notebook computer, a tablet computer and the like, and the terminal to be charged supports the second quick charge and the first quick charge. The second quick charging refers to a quick charging protocol utilizing CC channel communication in a Type-C interface, for example, PD quick charging. The first fast charging refers to other fast charging protocols which utilize D + and D-communication in a Type-C interface, such as VOOC fast charging protocol, QC2.0 fast charging protocol, QC3.0 fast charging protocol, PE fast charging protocol and FCP fast charging protocol. The power supply terminal is a terminal with a Type-C interface, and can be an adapter, a notebook computer, a tablet computer and the like, and the power supply terminal supports second quick charging, such as PD quick charging, and first quick charging, such as VOOC quick charging protocol, QC2.0 quick charging protocol, QC3.0 quick charging protocol, PE quick charging protocol and FCP quick charging protocol.

After the to-be-charged terminal is connected with the power supply terminal through the charging cable, the voltage of a VBUS pin of the charging cable connected to the to-be-charged terminal is detected, and when the voltage of the VBUS pin is detected to reach a preset voltage value, for example, 5V, the to-be-charged terminal can acquire the current battery state in the to-be-charged terminal, wherein the battery state comprises the electric quantity of a battery, the temperature of the battery and the like.

Step S20, judging whether the battery state meets a preset state corresponding to the first quick charge; if yes, go to step S30; if not, go to step S40;

after the current battery state is acquired by the terminal to be charged, the current battery state is compared with a preset state corresponding to a first quick charge stored in the terminal to be charged in advance, and whether the current battery state meets the preset state corresponding to the first quick charge is judged. And if the first charging mode is met, the terminal to be charged determines to select the first quick charging mode, and if the first charging mode is not met, the terminal to be charged selects the second quick charging mode or the common charging mode.

Step S30, a first fast charge request is sent to a power supply terminal through a communication channel corresponding to a first fast charge in the charging cable, so that the power supply terminal performs the first fast charge and closes the communication channel corresponding to a second fast charge in the charging cable according to the received first fast charge request;

if the current battery state meets the preset state corresponding to the first fast charge, after the terminal to be charged determines to select the first fast charge, the Type-C interface is used for sending a first fast charge request to the power supply terminal through the communication channels of the D + and the D-in the communication channel corresponding to the first fast charge in the charging cable, for example, the terminal to be charged sends 30 square wave signals with a period of 2 milliseconds and a duty ratio of 50% to the power supply terminal through the D + channel in the charging cable by using the Type-C interface. After receiving a first quick charging request sent by a terminal to be charged, the power supply terminal closes a communication channel corresponding to a second quick charging in the charging cable, and simultaneously enters a first quick charging working mode to perform first quick charging on the terminal to be charged.

Specifically, referring to fig. 3, fig. 3 is a detailed schematic view of the flow of step S30 in the embodiment of the present application, and based on the embodiment, step S30 includes:

step S31, a first fast charge request is sent to the power supply terminal through a communication channel corresponding to a first fast charge in the charging cable, so that the power supply terminal feeds back a first fast charge working signal and closes a communication channel corresponding to a second fast charge in the charging cable according to the received first fast charge request;

if the current battery state meets the preset state corresponding to the first fast charge, after the terminal to be charged determines to select the first fast charge, a first fast charge request is sent to the power supply terminal through communication channels corresponding to the first fast charge in the charging cable, namely communication channels of D + and D-in the Type-C interface, for example, the terminal to be charged sends 30 square wave signals with 2 milliseconds in period and 50% duty ratio to the power supply terminal through the D + channel in the charging cable by using the Type-C interface. After receiving a first quick charging request sent by a terminal to be charged, a power supply terminal closes a CC communication channel corresponding to a second quick charging in a charging cable, and feeds back a first quick charging working signal through a D + D-communication channel corresponding to the first quick charging in the charging cable.

Step S32, judging whether a first quick charging working signal fed back by the power supply terminal is received within a preset time; if yes, go to step S33; if not, go to step S34;

step S33, sending a battery state to the power supply terminal in real time through a communication channel corresponding to a first quick charge in the charging cable, so that the power supply terminal adjusts the charging voltage and the charging current in the first quick charge in real time according to the received battery state;

after the terminal to be charged sends the first fast charging request, the terminal to be charged waits for receiving a first fast charging working signal fed back by the power supply terminal within a preset time. If a first quick charging working signal fed back by the power supply terminal is received within the preset time, the terminal to be charged enters a non-PD working mode, the battery state is sent to the power supply terminal in real time through a first quick charging communication channel D + D-in the charging cable, and the power supply terminal correspondingly adjusts the charging voltage and the charging current of the first quick charging in real time through receiving the battery state of the terminal to be charged in real time. For example, in the first fast charging process, if the power amount of the battery of the terminal to be charged received by the power supply terminal is 10%, the power supply terminal may perform charging with the maximum current 6A of the first fast charging, and when the battery current of the terminal to be charged reaches 70%, the power supply terminal may decrease the charging current to 5A for charging.

Step S34, judging whether the number of times of continuously sending the first quick charging request reaches the preset number of times; if not, the process returns to step S31.

If the first fast charging working signal fed back by the power supply terminal is not received within the preset time, whether the number of times of continuously sending the first fast charging request reaches the preset number is judged, and if the number of times of continuously sending the first fast charging request does not reach the preset number, the first fast charging request is repeatedly sent.

It should be noted that, if the preset number of times is reached, it is determined that the first fast charging request is no longer sent to the power supply terminal, so that the request is prevented from being always initiated, and the subsequent charging process is prevented from being affected. After determining that the first quick charging request is not sent any more, the terminal to be charged automatically selects second quick charging or ordinary charging, and sends a second quick charging request or ordinary charging request to the power supply terminal through a communication channel corresponding to the second quick charging in the charging cable, so that the power supply terminal correspondingly carries out second quick charging or ordinary charging according to the received second quick charging request or ordinary charging request and closes the communication channel corresponding to the first quick charging in the charging cable.

Step S40, sending a second fast charge request or a normal charge request to the power supply terminal through a communication channel corresponding to a second fast charge in the charging cable, so that the power supply terminal correspondingly performs the second fast charge or the normal charge according to the received second fast charge request or the normal charge request, and closes the communication channel corresponding to the first fast charge in the charging cable.

If the current battery state does not meet the preset state corresponding to the first quick charge, the terminal to be charged can select to adopt the second quick charge or common charge, a second quick charge request or a common charge request is sent to the power supply terminal through a second quick charge communication channel, namely a CC channel, in the rewinder by utilizing a Type-C interface, and after the power supply terminal receives the second quick charge request or the common charge request through the second quick charge communication channel, namely the CC channel, in the rewinder, the communication channels corresponding to the first quick charge, namely the communication channels of D + and D-in the rewinder can be closed, and simultaneously the communication channels enter a second quick charge working mode or a common charge working mode to carry out the second quick charge or the common charge on the terminal to be charged.

Specifically, referring to fig. 4, fig. 4 is a detailed schematic view of the flow of step S40 in the embodiment of the present application, and based on the embodiment, step S40 includes:

step S41, judging whether the battery state meets the preset state corresponding to the second quick charge; if yes, go to step S42; if not, go to step S43;

step S42, sending a second fast charge request to the power supply terminal through a communication channel corresponding to a second fast charge in the charging cable, so that the power supply terminal performs the second fast charge and closes the communication channel corresponding to the first fast charge in the charging cable according to the received second fast charge request;

step S43, sending a common charging request to the power supply terminal through the communication channel corresponding to the second fast charge in the charging cable, so that the power supply terminal performs common charging and closes the communication channel corresponding to the first fast charge in the charging cable according to the received common charging request.

If the current battery state to be charged does not meet the preset state corresponding to the first quick charge, the terminal to be charged can continuously judge whether the battery state meets the preset state corresponding to the second quick charge. If the battery state of the terminal to be charged meets the preset state corresponding to the second quick charge, for example, the battery electric quantity of the terminal to be charged does not reach 90%, the terminal to be charged sends a second quick charge request to the power supply terminal through the CC communication channel corresponding to the second quick charge in the charging cable, and after the power supply terminal receives the second quick charge request, the communication channel corresponding to the first quick charge in the charging cable is closed, and the second quick charge working mode is adopted to start charging the terminal to be charged.

If the battery state of the terminal to be charged does not satisfy the preset state corresponding to the second quick charge, for example, the battery capacity of the terminal to be charged has reached 90%, the terminal to be charged sends a common charging request to the power supply terminal through the CC communication channel corresponding to the second quick charge, after receiving the common charging request, the power supply terminal closes the communication channel corresponding to the first quick charge in the charging cable, and starts to charge the terminal to be charged by using the charging voltage and the charging current corresponding to the common charge, for example, 5V 3A.

In the embodiment, the battery state of the terminal to be charged is obtained by detecting that the voltage value of a VBUS pin of a charging cable connected to the terminal to be charged reaches a preset voltage value; judging whether the battery state meets a preset state corresponding to the first quick charge; if so, sending a first quick charging request to a power supply terminal through a communication channel corresponding to a first quick charging in the charging cable, so that the power supply terminal performs the first quick charging according to the received first quick charging request and closes a communication channel corresponding to a second quick charging in the charging cable; if not, sending a second quick-charge request or a common charge request to the power supply terminal through a communication channel corresponding to a second quick charge in the charging cable, so that the power supply terminal correspondingly performs the second quick-charge or common charge and closes the communication channel corresponding to the first quick charge in the charging cable according to the received second quick-charge request or common charge request. After the terminal to be charged is connected with the power supply equipment, one of the second quick charging mode and the first quick charging mode can be selected according to the battery state of the terminal to be charged, the power supply equipment is informed of the mode of the charging request, the power supply equipment can close the communication channel of the unselected charging mode according to the charging mode selected by the charging equipment, and the communication channel of the selected charging mode is kept opened, so that the charging equipment can only output the requirements of charging voltage and charging current through one communication channel, and the power supply terminal can only receive the requirements of the charging voltage and the charging current once at the same time, thereby avoiding the problem that the output voltage and the current of the power supply terminal are disordered.

Further, a second embodiment of the charging control method of the present application is proposed according to the first embodiment of the charging control method of the present application, and in this embodiment, the step S10 further includes:

step S11, after detecting that the voltage value of a VBUS pin of a charging cable connected to the terminal to be charged reaches a preset voltage value, acquiring the battery state of the terminal to be charged, and receiving at least one second fast charging power output mode sent by the power supply terminal through a communication channel corresponding to a second fast charging in the charging cable, wherein the power output mode comprises charging voltage and charging current;

in this example, after the terminal to be charged is connected to the power supply terminal through the charging cable, the voltage of the VBUS pin of the Type-C interface of the charging cable connected to the terminal to be charged is detected, and when the voltage of the VBUS pin is detected to reach a preset voltage value, for example, 5V, the terminal to be charged acquires a current battery state in the terminal to be charged, and the terminal to be charged simultaneously receives at least one second fast-charging power output mode sent by the power supply terminal through a communication channel corresponding to a second fast-charging in the charging cable, where the power output mode includes a charging voltage and a charging current, for example, 9V3A, 15V3A, and the like.

In step S42, the step of sending a second fast charge request through a communication channel corresponding to a second fast charge in the charging cable to enable the power supply terminal to perform a second fast charge according to the received second fast charge request includes:

step S44, selecting one second fast charge power output mode from the received second fast charge power output modes;

step S45, a second fast charge request including the selected output power mode is sent to the power supply terminal through a communication channel corresponding to a second fast charge in the charging cable, so that the power supply terminal performs a second fast charge on the terminal to be charged according to the charging current and the charging voltage in the selected output power mode;

after the terminal to be charged determines to select the second quick charging working mode, a power output mode is selected from the previously received power output modes of the second quick charging according to a preset strategy; and then packaging the selected power output mode in a second quick charging request, sending the selected power output mode and the second quick charging request to the power supply terminal through a communication channel corresponding to the second quick charging in the charging cable, analyzing the power output mode, namely charging current and charging voltage, from the received PD charging request by the power supply terminal, and performing second quick charging on the terminal to be charged by adopting the charging current and the charging voltage.

The power supply terminal informs the power output mode of the second quick charge of the power supply terminal to the terminal to be charged, so that the terminal to be charged can select the optimal charging voltage and charging current of the second quick charge according to the self requirements such as the battery state after the second quick charge working mode is determined to be adopted, and the phenomenon that the charging time is too long due to damage of components in the terminal to be charged caused by overlarge charging voltage and charging current or due to overlong charging time caused by undersize charging current is avoided.

Referring to fig. 5, in a third embodiment of the charging control method of the present invention, the charging control method is applied to a power supply terminal, and the method includes the steps of:

step S50, judging whether a pull-down resistor of the terminal to be charged is detected;

after the power supply terminal is powered on, whether the pull-down resistor of the terminal to be charged is detected or not is continuously judged to determine whether the terminal to be charged is connected with the terminal to be charged or not.

Step S60, when the pull-down resistor of the terminal to be charged is detected, outputting a preset voltage value on a VBUS pin of a charging cable connected with the power supply terminal;

when the pull-down resistor of the terminal to be charged is detected, that is, after the connection with the terminal to be charged is confirmed, the power supply terminal outputs a preset voltage, for example, 5V, on the Vbus pin of the charging cable connected to the power supply terminal.

Step S70, monitoring whether a first quick charging request sent by the terminal to be charged through a communication channel corresponding to a first quick charging in the charging cable is received;

step S80, monitoring whether a second fast charging request or a normal charging request sent by the terminal to be charged through a communication channel corresponding to a second fast charging in the charging cable is received;

after the power supply terminal outputs the preset voltage on the VBUS pin, whether a first quick charging request sent by the terminal to be charged is received on a communication channel corresponding to a first quick charging mode or not can be monitored in real time, and whether a second quick charging request or a common charging request sent by the terminal to be charged is received on a communication channel corresponding to a second quick charging mode or not can be monitored in real time.

Step S70 and step S80 are performed simultaneously.

Step S90, if a first fast charge request sent by the terminal to be charged through a communication channel corresponding to a first fast charge in the charging cable is received, performing first fast charge on the terminal to be charged and closing a communication channel corresponding to a second fast charge in the charging cable according to the received first fast charge request;

when the power supply terminal monitors that a first quick charging request sent by the terminal to be charged through the D + and D-communication channels corresponding to the first quick charging in the charging cable is received, the terminal to be charged is subjected to first quick charging according to the received first quick charging request, and meanwhile, the CC communication channel corresponding to the second quick charging in the charging cable is closed, so that the condition that information or state fed back by the terminal to be charged is received only through the D + and D-communication channels corresponding to the first quick charging in the non-PD charging process is ensured.

Specifically, referring to fig. 6, fig. 6 is a detailed schematic view of the flow of step S90 in the embodiment of the present application, and based on the embodiment, step S90 includes:

step S91, according to the received first fast charging request, closing a communication channel corresponding to a second fast charging in the charging cable, and sending a first fast charging working signal to the terminal to be charged through the communication channel corresponding to the first fast charging in the charging cable, so that the terminal to be charged feeds back the battery state in real time through the communication channel corresponding to the first fast charging in the charging cable after receiving the first fast charging working signal;

and step S92, adjusting the charging voltage and the charging current of the first quick charge in real time according to the received battery state, and charging the terminal to be charged according to the adjusted charging voltage and charging current of the first quick charge.

After monitoring that a first quick-charging request sent by a terminal to be charged through communication channels corresponding to first quick-charging in the charging cable, namely communication channels of D + and D-, is received by the power supply terminal, for example, the first quick-charging request is a square wave signal with 30 cycles of 2 milliseconds and 50% duty ratio, a CC communication channel corresponding to second quick-charging in the charging cable is closed, and meanwhile, a first quick-charging working signal is sent to the terminal to be charged through the D + D-communication channel corresponding to the first quick-charging in the charging cable.

After receiving the first quick charging working signal within the preset time, the terminal to be charged enters a non-PD working mode, and simultaneously feeds back the battery state to the power supply terminal in real time through a communication channel D + D-of the first quick charging in the charging cable, and the power supply terminal correspondingly adjusts the charging voltage and the charging current of the first quick charging in real time through receiving the battery state of the terminal to be charged in real time. For example, in the first fast charging process, if the power amount of the battery of the terminal to be charged received by the power supply terminal is 10%, the power supply terminal may perform charging with the maximum current 6A of the first fast charging, and when the battery current of the terminal to be charged reaches 70%, the power supply terminal may decrease the charging current to 5A for charging.

Step S100, if a second quick charging request sent by the terminal to be charged through a communication channel corresponding to second quick charging in the charging cable is received, performing second quick charging on the terminal to be charged correspondingly and closing the communication channel corresponding to first quick charging in the charging cable according to the received second quick charging request;

if the power supply terminal monitors that a second quick charging request sent by the terminal to be charged through a second quick charging communication channel, namely a CC channel, in the charging cable is received, the power supply terminal closes the communication channels corresponding to the first quick charging in the charging cable, namely the communication channels of D + and D-, and simultaneously enters a second quick charging working mode to carry out second quick charging on the terminal to be charged.

Step S110, if a common charging request sent by the terminal to be charged through the communication channel corresponding to the second fast charge in the charging cable is received, performing common charging on the terminal to be charged correspondingly and closing the communication channel corresponding to the first fast charge in the charging cable according to the received common charging request.

If the power supply terminal monitors that a common charging request sent by the terminal to be charged through a second quick charging communication channel, namely a CC channel, in the charging cable is received, the power supply terminal closes communication channels corresponding to the first quick charging in the charging cable, namely communication channels of D + and D-, and simultaneously enters a common charging working mode to carry out common charging on the terminal to be charged.

The embodiment judges whether the pull-down resistor of the terminal to be charged is detected; when the pull-down resistor of the terminal to be charged is detected, outputting a preset voltage value on a VBUS pin of a charging cable connected with the power supply terminal; monitoring whether a first quick charging request sent by the terminal to be charged through a communication channel corresponding to a first quick charging in the charging cable is received or not, and simultaneously monitoring whether a second quick charging request or a common charging request sent by the terminal to be charged through a communication channel corresponding to a second quick charging in the charging cable is received or not; if a first quick charging request sent by the terminal to be charged through a communication channel corresponding to first quick charging in the charging cable is received, performing first quick charging on the terminal to be charged and closing the communication channel corresponding to the first quick charging in the charging cable according to the received first quick charging request; if a second quick charging request sent by the terminal to be charged through a communication channel corresponding to second quick charging in the charging cable is received, performing second quick charging on the terminal to be charged correspondingly and closing the communication channel corresponding to first quick charging in the charging cable according to the received second quick charging request; and if a common charging request sent by the terminal to be charged through a communication channel corresponding to the second quick charge in the charging cable is received, performing common charging on the terminal to be charged correspondingly and closing the communication channel corresponding to the first quick charge in the charging cable according to the received common charging request. After the power supply terminal is connected with the terminal to be charged, the power supply device can close the communication channel of the unselected charging mode according to the charging mode selected by the charging device, and keep the communication channel of the selected charging mode open, so that the power supply terminal can only receive the requirement of the charging voltage and the charging current sent by the terminal to be charged at one time, and the problem that the output voltage and the output current of the power supply terminal are disordered due to the requirement of the terminal to be charged on the charging voltage and the charging current sent by the two communication channels at the same time is avoided.

Further, referring to fig. 7, fig. 7 shows a fourth embodiment of the charging control method according to the third embodiment of the charging control method, and in this embodiment, after step S50, the method further includes:

step S120, when a pull-down resistor of the terminal to be charged is detected, at least one output power mode of a second quick charge is sent to the terminal to be charged through a communication channel corresponding to the second quick charge in the charging cable, wherein the output power mode comprises a charging voltage and a charging current;

when the pull-down resistance of the terminal to be charged is detected, namely after connection with the terminal to be charged is confirmed, at least one output power mode of a second quick charge is sent through a communication channel corresponding to the second quick charge in the charging cable so as to be selected by the terminal to be charged, wherein the power output mode comprises a charging voltage and a charging current, such as 9V3A, 15V3A and the like.

It should be noted that, the step S120 and the step S60 may be performed simultaneously, or the step S60 may be performed first, or the step S120 may be advanced, and the sequence between the step S60 and the step S120 is not limited in the present invention.
