Description

Charging method and terminal
Technical Field
The embodiment of the invention relates to the technical field of terminals, in particular to a charging method and a terminal.
Background
With the development of terminal technology, as the dependence of a user on a terminal is higher and higher, after the electric quantity of the terminal is consumed, the requirement of the user on the charging time of the terminal is higher and higher.
In general, a terminal may establish a charging system through a Universal Serial Bus (USB) and an adapter. Currently, a terminal determines whether the charging system can be charged quickly by detecting whether a charging interface of an adapter is a dedicated charging interface (DCP). If the charging interface is detected to be the DCP, the terminal determines that the adapter can be charged quickly (for example, charging can be performed by using a charging signal of 5V/1.5A); if the charging interface is detected to be non-DCP, the terminal determines that the adapter cannot be charged quickly, that is, the terminal can be charged by using a conventional charging method (for example, charging signal of 5V/0.5A can be used for charging).
However, in the above method, when the terminal detects whether the charging interface of the adapter is a DCP or not, the terminal may erroneously recognize the DCP of the adapter as a non-DCP due to insertion jitter when the user connects the terminal and the adapter, poor contact between the charging interface of the terminal and the charging interface of the adapter, and the like, and thus the terminal may be charged by using a conventional charging method, and thus, a charging time of the terminal may be prolonged.
Disclosure of Invention

In order to solve the above technical problem, the embodiment of the present invention is implemented as follows:
in a first aspect, an embodiment of the present invention provides a charging method, where the method includes: acquiring a detection result of the type of a charging interface of a charging device, wherein the detection result is a result of detecting the type of the charging interface for N times by adopting a first detection signal, the charging device is connected with a terminal, N is a first preset number of times, and N is a positive integer; if the detection result is a first result, detecting the type of the charging interface by adopting a second detection signal, wherein the first result is used for indicating that the type of the charging interface detected for N times is a non-dedicated charging interface DCP, the first detection signal is a detection signal generated by a power module of the terminal, and the second detection signal is a detection signal generated by a control module of the terminal; if the second detection signal is adopted to detect that the type of the charging interface is the DCP, the first detection signal is adopted again to detect the type of the charging interface; and if the first detection signal is adopted again to detect that the type of the charging interface is the DCP, adopting first power corresponding to the DCP to charge the terminal.
In a second aspect, an embodiment of the present invention further provides a terminal, where the terminal includes: the device comprises an acquisition module, a first detection module, a second detection module and a charging module; the acquisition module is used for acquiring a detection result of the type of a charging interface of a charging device, wherein the detection result is a result of detecting the type of the charging interface for N times by adopting a first detection signal, the charging device is connected with a terminal, N is a first preset number of times, and N is a positive integer; the first detection module is configured to detect the type of the charging interface by using a second detection signal if the detection result obtained by the obtaining module is a first result, where the first result is used to indicate that N times of detection of the types of the charging interfaces are all non-dedicated charging interfaces DCP, the first detection signal is a detection signal generated by a power module of the terminal, and the second detection signal is a detection signal generated by a control module of the terminal; the second detection module is configured to detect the type of the charging interface again by using the first detection signal if the first detection module detects that the type of the charging interface is DCP by using the second detection signal; the charging module is configured to charge the terminal with a first power corresponding to the DCP if the second detection module detects that the type of the charging interface is the DCP again by using the first detection signal.
In a third aspect, an embodiment of the present invention provides a terminal, including a processor, a memory, and a computer program stored on the memory and operable on the processor, where the computer program, when executed by the processor, implements the steps of the charging method according to the first aspect.
In a fourth aspect, the present invention provides a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, the computer program implements the steps of the charging method according to the first aspect.
In the embodiment of the invention, a terminal obtains a detection result of the type of a charging interface of a charging device, wherein the detection result is a result of detecting the type of the charging interface for N times by adopting a first detection signal, the charging device is connected with the terminal, N is a first preset number of times, and N is a positive integer; if the detection result is a first result, detecting the type of the charging interface by adopting a second detection signal, wherein the first result is used for indicating that the type of the charging interface detected for N times is a non-dedicated charging interface DCP, the first detection signal is a detection signal generated by a power module of the terminal, and the second detection signal is a detection signal generated by a control module of the terminal; if the second detection signal is adopted to detect that the type of the charging interface is the DCP, the first detection signal is adopted again to detect the type of the charging interface; and if the first detection signal is adopted again to detect that the type of the charging interface is the DCP, adopting first power corresponding to the DCP to charge the terminal. Firstly, after the terminal determines that the first result is detected by the first detection signal, the type of the charging interface is detected by the second detection signal, so that the detection times can be increased, and the detection mode is increased because the first detection signal is a detection signal generated by a power module of the terminal and the second detection signal is a detection signal generated by a control module of the terminal; furthermore, when the type of the charging interface is the DCP, the probability of detecting the type of the charging interface as the DCP can be improved; when the terminal detects that the type of the charging interface is the DCP by adopting the second detection signal, the terminal detects the type of the charging interface by adopting the first detection signal again, the detection times of adopting the first detection signal for detection are increased again, the probability that the type of the charging interface is detected as the DCP by adopting the first detection signal by the terminal is improved, namely, the probability that the terminal adopts the first power for charging is improved, and therefore the charging time of the terminal can be reduced.

Next, a software environment applied to the charging method provided by the embodiment of the present invention is described by taking an android operating system as an example.
Fig. 1 is a schematic diagram of an architecture of a possible android operating system according to an embodiment of the present invention. In fig. 1, the architecture of the android operating system includes 4 layers, which are respectively: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).
The application program layer comprises various application programs (including system application programs and third-party application programs) in an android operating system.
The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of complying with the development principle of the framework of the application.
The system runtime layer includes libraries (also called system libraries) and android operating system runtime environments.

Namely, the processor or the terminal device can implement the charging method provided by the embodiment of the invention by running the software program in the android operating system.
Fig. 2 is a schematic diagram of a charging system according to an embodiment of the present invention, as shown in fig. 2 (a), the charging system a includes a terminal 200, a charging line 21, and a charging device 22; the terminal 200 is connected to the charging device 22 through a charging cord 21. Wherein, the terminal 200 includes: an Application Processor (AP) 201, a Power Management Interface (PMIC) 202, and a Microcontroller (MCU) 203. Alternatively, as shown in fig. 2 (B), the terminal 210 includes: an AP201 and a PMIC 202. The PMIC202 detects the type of the charging interface by using a first detection signal, and the AP201 or the MCU203 detects the type of the charging interface by using a second detection signal. The AP201 is mainly used for controlling each application program in the terminal, the PMIC202 is mainly used for identifying and managing the charging device, the MCU203 is mainly used for detecting the type of a charging interface of the charging device, and the MCU203 may be an MCU having other functions in the terminal or an added MCU.
It should be noted that, in the embodiment of the present invention, the terminal may use the AP201 to detect the type of the charging interface of the charging device 22, or may use the MCU203 in the AP201 control terminal to detect the type of the charging interface of the charging device 22, which is not specifically limited in this embodiment of the present invention.
Fig. 3 is a schematic method flow diagram of a charging method according to an embodiment of the present invention, and the charging method according to the embodiment of the present invention is described below with reference to the charging system shown in fig. 2.
S301, the terminal obtains a detection result of the type of the charging interface of the charging device.
The detection result is that the terminal detects the type of the N-time charging interface by adopting a first detection signal, the charging device is a charging device connected with the terminal, N is a first preset time, and N is a positive integer.
Optionally, the terminal in the embodiment of the present invention may be a mobile phone, a tablet computer, a charger, and the like, and the charging device in the embodiment of the present invention may be an adapter, a charging head, a socket, a charger, a notebook, a host, and the like.
Generally, when the terminal supports fast charging, when detecting that the type of the charging interface of the charging device is DCP, the terminal may charge with a first charging power, and when detecting that the type of the charging interface of the charging device is non-DCP, the terminal may charge with a second charging power, where the first charging power is greater than the second charging power.
Specifically, with reference to fig. 2, the AP201 may obtain a detection result of the type of the charging interface of the charging device 22, where the detection result is that the PMIC202 detects the type of the charging interface N times by using the first detection signal.
In general, the PMIC may detect whether the charging interface of the charging device is DCP at a timing of BC1.2 (i.e., the PMIC transmits the first detection signal every 60ms, 40ms, and 20ms in sequence), and may detect that the type of the charging interface of the charging device is DCP within 6 times (i.e., N is 6), and then the terminal may be charged with the first power.
And S302, if the detection result is the first result, the terminal detects the type of the charging interface by adopting a second detection signal.
The first result is used for indicating that the types of the N times of detection charging interfaces are non-DCP, the first detection signal is a detection signal generated by a power module of the terminal, and the second detection signal is a detection signal generated by a control module of the terminal.
Optionally, the control module in the embodiment of the present invention may be an AP or an MCU in a terminal, which is not specifically limited in this embodiment of the present invention.
Specifically, with reference to fig. 2, when the detection result obtained by the AP201 from the PMIC202 on the type of the charging interface of the charging device 22 is a first result, the AP201 or the MCU203 may detect the type of the charging interface by using a second detection signal. When the terminal is the terminal 200 shown in (a) in fig. 2, the AP201 may instruct the switch to connect to the MCU203, and may detect the type of the charging interface by using the second detection signal through the MCU 203; when the terminal is the terminal 210 shown in (b) of fig. 2, the type of the charging interface may be detected by the AP201 using the second detection signal.
Optionally, the AP201 may output signals with different levels through a general purpose input/output (GPIO) to control on/off of the switch.
It should be noted that, when the detection result is the first result, the control module in the terminal may generate a second detection signal by simulating the timing sequence of BC1.2 through a software program, and detect the type of the charging interface by using the second detection signal.
It can be understood that the terminal in the embodiment of the present invention is a terminal capable of supporting fast charging, and when the terminal is a terminal that does not support fast charging, the terminal cannot perform fast charging even if the terminal detects that the type of the charging interface of the charging device is DCP.
And S303, if the terminal detects that the type of the charging interface is the DCP by adopting the second detection signal, the terminal detects the type of the charging interface by adopting the first detection signal again.
Specifically, with reference to fig. 2, if the MCU203 or the AP201 detects that the type of the charging interface is DCP by using the second detection signal, the PMIC202 in fig. 2 may detect the type of the charging interface by using the first detection signal again. With reference to the terminal 200 shown in (a) of fig. 2, first, when the MCU203 in the terminal 200 detects that the type of the charging interface is DCP, the MCU203 sends a message 1 to the AP201, where the message 1 is used to notify the AP201 to determine that the type of the charging interface of the charging device 22 is DCP; secondly, after receiving the message 1, the AP201 controls the switch to be connected to the PMIC202, and sends a message 2 to the PMIC202, where the message 2 is used to notify the PMIC202 to detect the type of the charging interface by using the first detection signal again; finally, when the PMIC202 receives the message 2, the PMIC202 detects the type of the charging interface again by using the first detection signal. In conjunction with the terminal 210 shown in fig. 2 (b), when the AP201 detects that the type of the charging interface is DCP, the AP201 controls the switch to connect to the PMIC202, and sends a message 2 to the PMIC202, where the message 2 is used to notify the PMIC202 to detect the type of the charging interface again by using the first detection signal; when the PMIC202 receives the message 2, the PMIC202 detects the type of the charging interface again by using the first detection signal.
It should be noted that "the terminal re-detects the type of the charging interface by using the first detection signal" in the embodiment of the present invention may be re-detected when the terminal and the charging device maintain the original connection, or re-detected when the terminal and the charging device reestablish the connection, which is not specifically limited in this embodiment of the present invention.
And S304, if the terminal detects that the type of the charging interface is the DCP by adopting the first detection signal again, the terminal charges the terminal by adopting the first power corresponding to the DCP.
It should be noted that, during charging, the terminal may be charged through the PMIC, or may not be charged through the PMIC, and this is not particularly limited in the embodiment of the present invention.
It can be understood that, in the embodiment of the present invention, the "terminal charges the terminal with the first power corresponding to the DCP" means that the terminal allows the charging device to output the first power to power the terminal, that is, the charging power acceptable to the terminal is the first power.
It should be noted that, when the type of the charging interface of the charging device is DCP, the charging power that the charging device can provide may include a first power and a second power, and when the terminal detects that the charging interface of the DCP type is not DCP, the terminal sends the indication information to the charging device to indicate that the charging device can charge with the second power, and then the charging power that the charging device provides to the terminal is the second power.
In the charging method provided by the embodiment of the invention, the terminal obtains the detection result of the type of the charging interface of the charging device, wherein the detection result is the result of detecting the type of the charging interface for N times by adopting a first detection signal, the charging device is connected with the terminal, N is a first preset number of times, and N is a positive integer; if the detection result is the first result, the terminal detects the type of the charging interface by adopting a second detection signal; the first result is used for indicating that the types of the charging interfaces detected for N times are non-DCP, the first detection signal is a detection signal generated by a power module of the terminal, the second detection signal is a detection signal generated by a control module of the terminal, and if the terminal detects that the type of the charging interface is DCP by adopting the second detection signal, the terminal detects the type of the charging interface by adopting the first detection signal again; if the terminal detects that the type of the charging interface is the DCP again by adopting the first detection signal, the terminal charges the terminal by adopting first power corresponding to the DCP. Firstly, after the terminal determines that the first result is detected by the first detection signal, the type of the charging interface is detected by the second detection signal, so that the detection times can be increased, and the detection mode is increased because the first detection signal is a detection signal generated by a power module of the terminal and the second detection signal is a detection signal generated by a control module of the terminal; furthermore, when the type of the charging interface is the DCP, the probability of detecting the type of the charging interface as the DCP can be improved; when the terminal detects that the type of the charging interface is the DCP by adopting the second detection signal, the terminal detects the type of the charging interface by adopting the first detection signal again, the detection times of adopting the first detection signal for detection are increased again, the probability that the type of the charging interface is the DCP by adopting the first detection signal is improved, namely, the probability that the terminal adopts the first power for charging is improved, and therefore the charging time of the terminal can be reduced.
In a possible implementation manner, after the terminal detects that the type of the charging interface is DCP using the second detection signal, the charging method further includes, before the terminal detects the type of the charging interface again using the first detection signal, S305:
s305, the terminal outputs prompt information.
The prompt message is used for instructing a user to reconnect the charging device and the terminal.
Specifically, with reference to fig. 2, after the AP201 or the MCU203 detects that the type of the charging interface is DCP by using the second detection signal, the AP201 may generate a prompt message and output the prompt message.
Optionally, the prompt information may be displayed in the notification bar, may also be displayed in a prompt box in the display interface, and may also be output in a voice to prompt the user to reconnect the charging device and the terminal.
Further, the "the terminal detecting the type of the charging interface again using the first detection signal" in S303 in the above-described charging method may be performed by W1:
w1, if the user reconnects the charging device to the terminal, the terminal detects the type of the charging interface again using the first detection signal.
Alternatively, the user may reconnect any one interface of the charging cord between the terminal and the charging device.
It should be noted that, after the charging device is reconnected with the terminal, the terminal detects the type of the charging interface again by using the first detection signal, and if the type of the charging interface is detected to be DCP after the detection is again performed, the terminal may be charged by using the first charging power corresponding to the DCP type.
Specifically, referring to fig. 2 (a), if the charging device 22 is reconnected to the terminal 200, the PMIC202 detects the type of the charging interface again by using the first detection signal.
It should be noted that, in the embodiment of the present invention, the AP201 is connected to the PMIC202 by default, when the terminal is charged or the connection between the terminal and the charging device 22 is disconnected, the AP201 controls the switch to the PMIC202, and when the terminal and the charging device 22 are reconnected, the terminal detects the type of the charging interface by default using the PMIC202 by using the first detection signal.
Based on the scheme, if the terminal detects that the type of the charging interface is the DCP according to the second detection signal, the terminal can output prompt information to the user to remind the user to reconnect the charging device and the terminal, and after reconnection, the terminal can adopt the first detection signal to detect the type of the charging interface again, so that the detection times are improved, the probability of accurate type detection of the charging interface is increased, the charging can be carried out by adopting the first power more probably, and the charging time of the terminal is reduced.
Specifically, W1 in the above charging method may be performed by W2:
w2, if the target connection times are smaller than the second preset times, the terminal detects the type of the charging interface again by adopting the first detection signal.
The target connection frequency is the frequency of connecting the charging device and the terminal by a user in a target time period, and the target time period is a time period from detecting that the type of the charging interface is DCP by adopting the second detection signal to detecting that the type of the charging interface is DCP by adopting the first detection signal again.
It should be noted that, when the connection frequency between the charging device and the terminal is less than the second preset frequency, the terminal still has the first result after detecting the type of the charging interface by using the first detection signal, and if the terminal detects that the type of the charging interface is DCP by using the second detection signal, the terminal may detect the type of the charging interface by using the first detection signal again.
Optionally, the second preset number may be the same as the first preset number, or may be different from the first preset number, which is not specifically limited in this embodiment of the present invention.
Based on the scheme, if the target connection times are smaller than the second preset times, the type of the charging interface is detected by the terminal through the first detection signal again, and the times of detecting the type of the charging interface by the terminal are increased, so that the accuracy of detecting the type of the charging interface can be improved, the probability of detecting the DCP as the non-DCP is reduced, the probability of charging the terminal with high power is improved, and the charging time of the terminal is shortened.
Optionally, after the user reconnects the charging device to the terminal, the charging method further includes S306:
and S306, if the target connection times are equal to a second preset time, the terminal charges the terminal by adopting a second power corresponding to the non-DCP, and the second power is smaller than the first power.
It can be understood that when the connection times are equal to the second preset times, the PMIC in the terminal still has the first result after detecting the type of the charging interface by using the first detection signal, and then the probability that the charging interface of the charging device is the non-DCP is relatively high, even if the user is prompted to reconnect, the PMIC detection result may still be the non-DCP, therefore, the terminal charges the terminal by using the second power corresponding to the non-DCP, and the damage to the terminal caused by the charging power larger than the second power used by the terminal, for example, an accident caused by the terminal heating due to the excessive current, and the burning of components in the terminal due to the excessive voltage, can be avoided.
Optionally, when the terminal detects the type of the charging interface by using the second detection signal, the charging method further includes S307:
and S307, if the terminal detects that the type of the charging interface is the non-DCP by adopting the second detection signal, the terminal charges the terminal by adopting second power corresponding to the non-DCP, and the second power is smaller than the first power.
Based on the scheme, the first result is detected at the terminal, and the terminal detects that the type of the charging interface is the non-DCP by adopting the second detection signal, so that the fact that the type of the charging interface of the charging device has higher probability of being the non-DCP is shown, therefore, the probability that the terminal is damaged by adopting higher charging power for charging the terminal can be reduced by adopting the second power corresponding to the non-DCP by the terminal, and the terminal is further safer to charge.
It can be understood that the terminal detects the type of the charging interface again by using the first detection signal, and the detection result may be DCP or non-DCP, and optionally, the charging method further includes S308:
and S308, if the terminal detects that the type of the charging interface is non-DCP again by adopting the first detection signal, the terminal continues to detect the type of the charging interface by adopting the first detection signal until the detection times reach P times, the detection results of the P times are all non-DCP, P is a third preset time, and P is a positive integer.
It can be understood that, in the conventional detection method, when the type of the charging interface is detected to be DCP by using the first detection signal, the terminal may be charged by using the first power, and when the type of the charging interface is detected to be DCP for 6 times (that is, N is 6), the terminal may be charged by using the second power if the type of the charging interface is determined not to be DCP. In the embodiment of the invention, after the user reconnects the terminal and the charging device according to the prompt message and the type of the charging interface is detected again by adopting the first detection signal, if the P times are detected to be non-DCP, the type of the charging interface is considered not to be DCP, at the moment, if the target connection times do not reach the second preset times, the terminal continues to detect the type of the charging interface again by adopting the first detection signal until the target connection times reach the second preset times.
It should be noted that P in the embodiment of the present invention may be the same as N or may not be the same as N, and this is not particularly limited in the embodiment of the present invention.
Optionally, the charging method S303 may be executed through S303 a:
and S303a, if the terminal detects that the type of the charging interface is DCP by continuously adopting the second detection signal for M times, the terminal detects the type of the charging interface by adopting the first detection signal again, wherein M is a fourth preset number of times, and M is a positive integer.
Specifically, with reference to fig. 2, the fourth preset time is used to improve the accuracy of detecting that the type of the charging interface is DCP by the AP201 or the MCU203, after the AP201 or the MCU203 starts to use the second detection signal for detection, if the AP201/MCU203 continuously detects that the type of the charging interface is DCP by using the second detection signal for the fourth preset time, it indicates that the possibility that the type of the charging interface is DCP is relatively high, and at this time, the PMIC202 in the reuse terminal detects that the type of the charging interface is DCP by using the first detection signal again, and the probability of detecting that the type of the charging interface is DCP is relatively high.
Based on the scheme, before the terminal detects the type of the charging interface again by adopting the first detection signal, if the terminal detects that the type of the charging interface is DCP by adopting the second detection signal for M times continuously, the possibility that the type of the charging interface of the charging device connected with the terminal is DCP is higher, at the moment, the terminal detects the type of the charging interface again by adopting the first detection signal, the detection times for detecting the type of the charging interface are increased, the successful detection probability that the type of the charging interface is DCP is improved, the probability that the terminal charges by adopting the first power is further improved, and therefore the charging time of the terminal is shortened.
Exemplarily, fig. 4 is a schematic flowchart of a charging method according to an embodiment of the present invention, and with reference to fig. 2, the flowchart of the charging method in fig. 4 includes the following steps:
(1) if the terminal detects that the type of the charging interface is the non-DCP by using the first detection signal again in the above method embodiment, the terminal continues to detect the type of the charging interface by using the first detection signal until P times are reached, where P is not equal to N, as shown in (a) in fig. 4, the method includes the following steps:
after the terminal 200 and the charging device 22 are connected through the charging line 21, the switch is connected to the PMIC 202.
Step 1: the PMIC202 detects the type of the charging interface of the charging device 22 according to the first detection signal.
It should be noted that, after the connection is established for the first time, it is not necessary to determine whether the charging path is the target connection, and after the user reconnects the terminal and the charging device according to the prompt information, it is necessary to determine whether the charging path is the target connection, where the target connection is the connection that is reestablished by the user according to the prompt information.
If the PMIC202 detects that the type of the charging interface is DCP, the terminal 210 may be charged with the first power.
If the PMIC202 detects that the type of the charging interface is non-DCP according to the first detection signal, the detected number of times of the PMIC202 is increased by 1.
Step 2: it is determined whether the number of detections of the PMIC202 is less than or equal to N.
If the detected number of times by the PMIC202 is less than N, the PMIC202 detects the type of the charging interface of the charging device 22 again according to the first detection signal.
If the number of detections that the PMIC202 has detected is equal to N, the PMIC202 sends a notification message 1 to the AP201, where the notification message is used to indicate that the type of the charging interface of the charging device 22 is detected as non-DCP N times (i.e., a first result).
And step 3: after the AP201 obtains the first result, the control switch is switched from the PMIC202 to the MCU203, that is, the AP201 and the MCU203 establish connection with the charging device 22 through the charging line 21.
And 4, step 4: after the AP201 and the MCU203 establish connection through the charging line 21 and the charging device 22, the MCU203 detects whether the type of the charging interface is DCP according to the second detection signal.
If the MCU203 detects that the type of the charging interface is non-DCP, the MCU203 sends a notification message 2 to the AP201, where the notification message 2 is used to indicate that the result detected by the MCU203 is non-DCP, and the terminal 200 may be charged with the second power.
If the MCU203 detects that the type of the charging interface is DCP, the MCU203 sends a notification message 3 to the AP201, where the notification message 3 is used to indicate that the detected result of the MCU203 is DCP, and the AP201 generates and outputs a prompt message for prompting the user to reconnect the charging device 22 with the terminal 200.
And 5: AP201 detects that the user reconnects terminal 200 and charging device 22; after the reconnection, it is determined whether the number of times of detection by the PMIC202 of the type of charging interface of the charging device 22 according to the first detection signal is less than or equal to P.
If the detected number of times by the PMIC202 is less than P, the PMIC202 detects the type of the charging interface of the charging device 22 again according to the first detection signal.
If the detected number of times by the PMIC202 is equal to P, the PMIC202 sends a notification message 4 to the AP201, where the notification message 4 is used to indicate that the type of the charging interface of the charging device 22 is detected as non-DCP P times (denoted as a second result).
Step 6: after the AP201 obtains the second result, the switch is controlled to switch from the PMIC202 to the MCU203, that is, the AP201 and the MCU203 establish a connection with the charging device 22 through the charging line 21.
If the MCU203 detects that the type of the charging interface is still non-DCP, the target connection time is equal to Q (i.e., a second preset time), and Q is a positive integer, the terminal charges with a second power.
After the charging is completed, the AP201 controls the switch to switch from the MCU203 to the PMIC 202.
If the target connection number is less than Q, the PMIC202 detects the type of the charging interface of the charging device 22 again according to the first detection signal (i.e., continues to perform step 5).
(2) If the terminal detects that the type of the charging interface is the non-DCP by using the first detection signal again in the above method embodiment, the terminal continues to detect the type of the charging interface by using the first detection signal until P equals N in the detection times reaching P times, "as shown in (b) in fig. 4: in the charging method process, it is not necessary to detect whether the charging path is the target connection, and the switch is connected to the PMIC, then the PMIC202 detects the type of the charging interface of the charging device 22 by using the first detection signal, and determines whether the detection frequency is less than or equal to N (i.e., step 5 may be performed by using step 2, and the second result in step 5 is the first result). The description of the other steps may refer to the description of the relevant steps in (a) in fig. 4.
It can be understood that when the terminal detects that the type of the charging interface of the charging device is non-DCP after detecting P times according to the first detection signal again, the terminal detects again by using the second detection signal, so that the detection times are increased, and if the type of the charging interface is DCP, the probability that the terminal detects the type of the charging interface as DCP is improved, and then the probability that the terminal charges by using the first power is improved, so that the charging time of the terminal can be reduced.
