Detailed ways

Please refer to the drawings, wherein the same component symbols represent the same components, and the principles of the present application are exemplified by being implemented in a suitable computing environment. The following description is based on illustrated specific embodiments of the present application and should not be construed as limiting other specific embodiments of the present application not detailed herein.

Embodiments of the present application provide a charging processing method, a charging processing circuit, an electronic device, and a storage medium. The detailed descriptions will be given below.

Please refer to FIG. 1 . FIG. 1 is a schematic diagram of a first structure of a charging processing circuit provided by an embodiment of the present application. 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 to connect with the charging input interface 310 of the device to be charged 300 . The charging output interface 210 may be a Universal Serial Bus (Universal Serial Bus, USB) interface. Specifically, the charging output interface 210 may be a Micro USB interface or a Type-C interface, etc. Of course, the charging output interface 210 may also be other interfaces. When the charging output interface 210 is a Type-C interface, since the Type-C interface has many pins and the width of the Type-C interface is limited, the distance between the pins of the Type-C interface is relatively small, and foreign objects or liquids can enter. At this time, it is easy to cause a micro short circuit, thereby causing the temperature at the Type-C interface to rise, thereby burning out the charging output interface 210 .

The detection module 220 is connected to the charging output interface 210 , and the detection module 220 is used to obtain the connection state between the charging output interface 210 and the charging input interface 310 . The detection module 220 is configured to detect the 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 device 200 and the device to be charged 200 have been physically connected, for example, the charging output interface 210 of the charging device 200 is inserted into the charging input interface 310 of the device to be charged 300 . The unconnected state indicates that the charging device 200 and the device to be charged 200 have not been physically connected. For example, the charging output interface 210 of the charging device 200 is floating and 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. When the connection state is the unconnected state, it stops outputting the charging signal through the charging output interface 210, and when the connection state is the connected state, it communicates with the device to be charged 300. , and when the communication succeeds, output the charging signal through the charging output interface 210 , and when the communication fails, stop outputting the charging signal through the charging output interface 210 .

When the connection state is the unconnected state, stop outputting the charging signal. When the charging device 200 and the device to be charged 300 are not connected, that is, when the charging output interface 210 of the charging device 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 device to be charged 300 , the charging device 200 starts to communicate with the device to be charged 300 . For example, the charging apparatus 200 may actively send a connection request to the device to be charged 300 , or may receive a connection request sent by the device to be charged 300 . After the charging apparatus 200 successfully communicates with the device to be charged 300, a charging signal is output. Specifically, it can be understood that after the charging apparatus 200 sends a connection request, after receiving the reception request information returned by the device to be charged 300, after identifying the reception request information, it is determined that the communication is successful, and then a charging signal is output. It can also be understood that after receiving the connection request sent by the device to be charged 300, the charging apparatus 200 recognizes the connection request, and returns the receiving request information to the device to be charged 300 to determine that the communication is successful, and then outputs a charging signal.

When communicating with the device to be charged 300, if the charging device 200 fails to recognize the connection request after receiving the connection request sent by the device to be charged 300, or the connection request is an illegal connection request, it is considered that the communication fails. Alternatively, if the charging apparatus 200 sends a connection request to the device to be charged 300, and does not receive the returned reception request information, or receives illegal reception request information, it is also considered that the communication fails. After the communication fails, it stops outputting the charging signal.

Wherein, the first functional element R1 may be not only a resistor, but also an element such as a capacitor. The first output pin SBU1 and the second output pin SBU2 are connected through the first functional element R1. Before the charging output interface 210 and the charging input interface 310 are connected, the charging device 200 does not provide the first output pin SBU1 and the second output pin SBU1 and the second output pin. The pin SBU2 supplies power or provides a fixed value. After the charging output interface 210 and the charging input interface 310 are connected, the charging input interface 310 provides a voltage to the second output pin SBU2 and grounds the first output pin SBU1 to form 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 current, or the second output pin SBU2 has a fixed voltage and current. After the loop is formed, the voltage and current of the second output pin SBU2 change, and then the detection voltage or the detection current of the second output pin SBU2 is detected. When the detection voltage or detection current of the second output pin SBU2 is 0 or a fixed value, the connection state is determined to be an unconnected state, and when the detection voltage or detection current of the second output pin SBU2 is a changed value, Then it is determined that the connection state is the connected state.

Wherein, the second functional element R2 may be not only a resistor, but also an element such as a capacitor.

Please refer to FIG. 4 , which is a schematic diagram of a third structure of the charging processing circuit provided by the embodiment of the present application.

The first output pin SBU1 and the second output pin SBU2 are connected through the fifth functional element R5 and the second switching element 250, and the fifth functional element R5 and the first functional element R1 are connected in parallel. When the detection module 220 detects that the connection state is the connected state, it controls the second switch element 250 to switch from on to off, or from off to on, so as to change the first output pin SBU1 and the second output pin impedance between SBU2, thereby changing voltage and current. After detecting the change, the detection module 220 sends a new voltage or a new current to the device to be charged 300 to prompt the charging device 200 to be the original charging device 200 . When the original charging device 200 is used, high-power fast charging can be performed, and when the non-original charging device 200 is used, low-power slow charging can be performed.
