The high-power charging output refers to charging output with the power of 65W-240W, even charging output above 240W, wherein the voltage is 9-48V, and the current is 5-12A; the non-high power refers to power below 65W.
The electronic tag chip 33, the PD decoy device 32 and the MCU chip 34 are all arranged on the PCB 31, the PCB 31 is arranged in the Type-C plug 12 of the Type-C charging wire 1, the PCB 31 is also connected with the connecting wire 11, and the other end of the connecting wire 11 is connected with the non-quick-charging physical interface 13.
The negative electrode of the non-fast charging physical interface 13 is connected with a protection switch 36 and then is connected with the ground, the negative electrode of the non-fast charging physical interface 13 is connected with the VBUS end of the Type-C plug 12, the MCU chip 34 is connected with an electronic switch to control the protection switch 36 to be conducted, the MCU chip 34 is connected with an output voltage detection circuit 37, the output voltage detection circuit 37 is connected with the VBUS end and detects the voltage of the VBUS end, the MCU chip 34 judges whether the actual voltage of the VBUS end detected in the charging process is consistent with the output voltage specified by the PD trap 32 or not, when the actual voltage is consistent with the output voltage, the MCU chip 34 controls the protection switch 36 to be conducted to realize charging, when the actual voltage is inconsistent with the output voltage, the MCU chip 34 judges that the actual voltage of the VBUS end detected in the charging process is excessively changed, the MCU chip 34 also controls the protection switch 36 to be cut off to cut off a charging loop to achieve the purpose of protecting the device 100, and therefore the protection mechanism is achieved, and the invention is safer and more reliable in use.
More specifically, the protection switch 36 is a MOS transistor, a G pole of the MOS transistor is connected to the MCU chip 34, a D pole of the MOS transistor is connected to the negative pole of the non-fast charging physical interface 13, and an S pole of the MOS transistor is connected to ground. When the MOS transistor is turned on, the negative electrode of the non-fast charging physical interface 13 is grounded, so that a charging loop is realized.
Or, a protection switch 36 is connected between the positive electrode of the non-fast charging physical interface 13 and the VBUS terminal, the negative electrode of the non-fast charging physical interface 13 is grounded, the MCU chip 34 is connected to the protection switch 36 to control the protection switch 36 to be turned on, the MCU chip 34 is connected to an output voltage detection circuit 37, the output voltage detection circuit 37 is connected to the VBUS terminal and detects the voltage at the VBUS terminal, the MCU chip 34 determines whether the actual voltage at the VBUS terminal detected during the charging process is consistent with the output voltage specified by the PD spoofer 32, the MCU chip 34 controls the protection switch 36 to be turned on to realize charging when the actual voltage at the VBUS terminal is consistent with the output voltage specified by the PD spoofer 32, and the MCU chip 34 controls the protection switch 36 to be turned off and not to charge when the actual voltage at the VBUS terminal is inconsistent with the actual voltage at the VBUS terminal. The protection switch 36 is only connected between the positive electrode of the non-fast-charging physical interface 13 and the VBUS terminal, but not between the negative electrode of the non-fast-charging physical interface 13 and the ground, but the principle and the achieved effect are the same. The only difference is that the protection switch 36 needs to use two MOS transistors in cascade, which is relatively expensive.
It is worth mentioning that: the MOS tube is used for monitoring whether the charging voltage of the positive electrode and the charging voltage of the negative electrode of the non-quick-charging physical interface 13 are abnormal or not, if the charging voltage is abnormal, the MOS tube is controlled to cut off a loop through the MCU chip, so that the power loop is disconnected to prevent the damage caused by the abnormal charging, the monitoring and cutting-off protection function is used as an option, the high-power product circuit protection can meet the high-power supply function according to actual requirements, and the MOS tube circuit protection is selected to further improve the safety.
The non-fast charging physical interface 13 is an interface without executing protocol communication, and is only used for conducting power supply. Specifically, the non-fast-charging physical interface 13 is any one of a DC circular interface, an associative square interface, a Pogo pin connector, and a pin header, and these are all directly-inserted non-fast-charging physical interfaces without execution protocol communication, so that a Type-C plug is inserted into the PD adapter 2 to realize output, and any one of the DC circular interface, the associative square interface, the Pogo pin connector, and the pin header is used as output, so as to realize high-power charging of the devices 100 of different models, and realize charging use of the devices 100 corresponding to one another. When the non-quick charging physical interface 13 adopts a DC circular interface, the Type-C charging wire 1 realizes a Type-C TO DC circular interface; when the non-fast charging physical interface 13 adopts a Pogo pin connector, the Type-C charging wire 1 realizes a Type-C TO Pogo pin connector; when the non-quick charging physical interface 13 adopts an associative square interface, the Type-C charging wire 1 realizes a Type-C TO associative square interface; when the non-quick charging physical interface 13 adopts pin arrangement, the Type-C charging wire 1 realizes Type-C TO pin arrangement; of course, the non-fast charging physical interface 13 may also be other types of interfaces/connectors, and different interfaces/connectors may be selected according to actual use requirements. It should be noted that no matter which type of interface is used for communication without the execution protocol, the non-fast charging physical interface 13 is ultimately aimed at outputting high power to the notebook computer or other device 100 to perform fast charging.
The non-fast charging physical interface 13 may perform ID identification with the device 100 through resistance, voltage, or current, and when the resistance, voltage, or current value of the non-fast charging physical interface 13 matches the resistance, voltage, or current value set by the device 100, the non-fast charging physical interface 13 is turned on with the device 100 to charge the device 100.
Specifically, when the non-fast-charging physical interface 13 can perform ID identification with the device 100 through a resistor, a resistor is connected in the non-fast-charging physical interface 13, after the non-fast-charging physical interface 13 is inserted into an interface of the device 100, the interface of the device 100 detects a resistance value of the resistor, and after the resistance value of the resistor is matched with a preset resistance value, the non-fast-charging physical interface 13 is conducted with the interface of the device 100, and at this time, the non-fast-charging physical interface 13 charges the device 100, so that the abnormal charging of the device 100 due to the abnormal charging of the device 100 by a non-matched PD adapter and a Type-C charging wire can be avoided, and the device 100 is not normally charged according to a PD protocol to damage the device 100 or the device 100 is abnormal, and the use is safer and more reliable.

Therefore, the invention can realize the high-power rapid charging function of the PD on the equipment 100 without the rapid charging physical interface by matching the Type-C charging wire 1 with the PD adapter 2, solves the problem that the non-rapid charging physical interface of the equipment 100 cannot communicate with the rapid charging protocol, and can output high-power charging by the protocol communication between the Type-C plug 12 of the Type-C charging wire 1 and the PD adapter 2, and the current and the voltage can output larger values, for example: the non-quick charging physical interface 13 at the output end of the charging line 1 with the voltage of 9-48V and the voltage of 5-12A and the type-C is used as a pure interface connection device 100 without execution protocol communication, and different powers are output through the non-quick charging physical interface 13 according to different quick charging protocols to charge the device 100 with high power or without high power so as to meet different charging requirements.
