Detailed Description
Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present application are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein.
The embodiment of the application provides a charging processing method, a charging processing circuit, an electronic device and a storage medium. The details will be described below separately.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating a first structure of a charging processing circuit according to an embodiment of the present disclosure. The charging processing circuit includes a charging output interface 210, a detection module 220, and an output control module 230.
The charging output interface 210 is used for connecting with the charging input interface 310 of the device 300 to be charged. The charging output interface 210 may be a Universal Serial Bus (USB) interface. Specifically, the charging output interface 210 may be a Micro USB interface or a Type-C interface, and the charging output interface 210 may also be another interface. When the output interface 210 that charges is the Type-C interface, because the pin of Type-C interface is more, and the width of Type-C interface is limited, consequently the interval between Type-C interface pin is less, when advancing foreign matter or feed liquor, causes little short circuit easily to lead to the temperature rise at Type-C interface, thereby burns out the output interface 210 that charges.
The detection module 220 is connected to the charging output interface 210, and the detection module 220 is configured to obtain a connection state between the charging output interface 210 and the charging input interface 310. The detection module 220 is used for detecting a connection state between the charging output interface 210 of the charging device 200 and the charging input interface 310 of the device to be charged 200. The connection state includes a connected state and an unconnected state, the connected state indicates that the charging apparatus 200 and the apparatus to be charged 200 have been physically connected, such as the charging output interface 210 of the charging apparatus 200 is plugged into the charging input interface 310 of the device to be charged 300. The unconnected state indicates that the charging apparatus 200 and the apparatus to be charged 200 have not been physically connected, for example, the charging output interface 210 of the charging apparatus 200 is floating and is not connected to the device to be charged 300.
The charging output interface 210 and the detection module 220 are both connected to the output control module 230, and stop outputting the charging signal through the charging output interface 210 when the connection state is the unconnected state, communicate with the device 300 to be charged when the connection state is the connected state, and output the charging signal through the charging output interface 210 when the communication is successful, and stop outputting the charging signal through the charging output interface 210 when the communication is failed.
And when the connection state is the disconnection state, stopping outputting the charging signal. When the charging apparatus 200 and the device to be charged 300 are in an unconnected state, that is, the charging output interface 210 of the charging apparatus 200 is not connected to the device to be charged 300, the output of the charging signal is also stopped.
When the connection state is the connected state, that is, after the charging device 200 is physically connected to the apparatus to be charged 300, the charging device 200 starts communication with the apparatus to be charged 300. For example, the charging apparatus 200 may actively transmit a connection request to the device to be charged 300, or may receive a connection request transmitted by the device to be charged 300. When the charging device 200 and the device 300 to be charged successfully communicate, a charging signal is output. Specifically, it may be understood that, after the charging device 200 transmits the connection request and receives the reception request information returned by the device to be charged 300, the charging device identifies the reception request information, determines that the communication is successful, and then outputs the charging signal. It is also understood that, after receiving the connection request sent by the device to be charged 300, the charging apparatus 200 recognizes the connection request, returns the reception request information to the device to be charged 300, determines that the communication is successful, and then outputs the charging signal.
When communicating with the device 300 to be charged, the charging apparatus 200 receives the connection request sent by the device 300 to be charged, and then the connection request cannot be recognized, or if the connection request is an illegal connection request, the communication is considered to have failed. Further, the charging apparatus 200 may send a connection request to the device to be charged 300, and if the returned reception request information is not received or an illegal reception request information is received, the communication is also considered to have failed. And stopping outputting the charging signal after the communication fails.

In some embodiments, the charging output interface 210 includes a first output terminal SBU1 and a second output terminal SBU2, the first output terminal SBU1 is connected to the second output terminal SBU2 through a first functional element R1, and the first output terminal SBU1 and the second output terminal SBU2 form a loop through the charging input interface 310.
The detection module 220 is connected to the second output terminal SBU2 and obtains a detection voltage or a detection current of the second output terminal SBU2, and the detection module 220 is configured to obtain a connection state of the charging output interface 210 and the charging input interface 310 by detecting a change of the detection voltage or the detection current.
The first functional element R1 may be a resistor or a capacitor. The first output pin SBU1 and the second output pin SBU2 are connected through the first functional device R1, before the charging output interface 210 and the charging input interface 310 are connected, the charging device 200 does not supply power to the first output pin SBU1 and the second output pin SBU2 or supplies a fixed value, after the charging output interface 210 and the charging input interface 310 are connected, the charging input interface 310 supplies voltage to the second output pin SBU2 and grounds the first output pin SBU1, thereby forming a loop. Before the charging output interface 210 and the charging input interface 310 are not connected, the first output pin SBU1 and the second output pin SBU2 have no voltage and no current, or the second output pin SBU2 has a fixed voltage and no current. After the loop is formed, the voltage and the current of the second output terminal SBU2 change, and then the detection voltage or the detection current of the second output terminal SBU2 is detected. When the detected voltage or the detected current of the second output terminal SBU2 is 0 or a fixed value, the connection status is determined as unconnected status, and when the detected voltage or the detected current of the second output terminal SBU2 is a changed value, the connection status is determined as connected status.
It should be noted that, in this embodiment, the first output pin and the second output pin may be non-power supply pins, and a Type-C interface is taken as an example, as shown in fig. 3, the first output pin may be other than SBU1, and may also be one of pins GND, TX1+, TX1-, TX2+, TX2-, RX1+, RX1-, RX2+, RX2-, SBU2, CC1, and CC2 as needed, and the second output pin may be other than SBU2, and may also be one of pins TX1+, TX1-, TX2+, TX2-, RX1+, RX1-, RX2+, RX2-, SBU1, CC1, and CC2 as needed.
In some other embodiments, the second functional element R2 of the charging input interface 310 is connected in series with the first functional element R1, i.e., the second input pin in the charging input interface 310 is connected to the second output pin SBU2 through a third functional element. The second functional element R2 may be a resistor, a capacitor, or the like.
Referring to fig. 4, fig. 4 is a schematic diagram of a third structure of a charging processing circuit according to an embodiment of the present disclosure. In some embodiments, the first output pin SBU1 and the second output pin SBU2 are further connected through the fifth functional element R5 and the second switching element 250.

The first output pin SBU1 and the second output pin SBU2 are connected to each other through a fifth functional element R5 and a second switching element 250, and the fifth functional element R5 is connected in parallel to the first functional element R1. When the detection module 220 detects that the connection state is the connected state, the second switching element 250 is controlled to switch from on to off or from off to on, so as to change the impedance between the first output pin SBU1 and the second output pin SBU2, thereby changing the voltage and the current. After detecting the change, the detecting module 220 sends a new voltage or a new current to the device to be charged 300 to prompt the charging apparatus 200 to be the original charging apparatus 200. When the original charging device 200 is used, high-power quick charging can be performed, and when the original charging device 200 is not used, low-power slow charging can be performed.
In some embodiments, the charging input interface 310 includes a first input pin and a second input pin, the first input pin is grounded, the first input pin is connected to the first output pin SBU1, the second input pin is connected to the second output pin SBU2 through the second functional element R2, and the second input pin has a voltage.

The first functional element R1 and the second functional element R2 divide the voltage, and determine whether the current connection state is the connected state or the unconnected state by detecting the voltage of the second input pin or the second output pin SBU 2.

Taking the Typc-C interface as an example, the third output pin may be a CC pin, the fourth output pin may be a power input pin VBUS, and an identification signal (e.g., a pulse signal) is sent out at the CC pin at intervals. After the charging input interface 310 is connected to the charging output interface 210, one end of the charging input interface 310 connects the CC pin and the VBUS pin, so that the VBUS pin receives an identification signal, and the charging device 200 sends a charging request to the device 300 to be charged through D +/-upon detecting the identification signal. After the charging is started, the CC pin of the charging device 200 stops sending the pulse signal.
