In this embodiment, the working principle of the first processing circuit 111 is: when the controller 1 is in the dormant state and the first terminal 111a of the first processing circuit 111 does not recognize the input signal of the charging gun, the input signal of the charging gun The outside is suspended, and the power supply module 14 will not send a power supply signal to the processing module 11 . Therefore, the first transistor D1 of the first processing circuit 111 is in an off state, and due to the effects of the third resistor R3 and the fourth resistor R4, the gate G and source S voltages of the second transistor D2 are equal and are provided by the battery 2 The normal electric voltage, so D2 is also turned off. The R5 resistor is floating and does not function as a pull-up.

When the charging gun insertion end of the controller 1 recognizes the charging gun input signal, the controller 1 enters the wake-up state, the power supply module 14 is activated, and sends a power supply signal to the first processing circuit 111.

When the first terminal 111a of the processing module 111 recognizes the input signal of the charging gun, the charging resistor R0 in the charging gun pulls the node voltage of the seventh resistor R7 and the third transistor D3 through the sixth resistor R6 and the third transistor D3 Low. The second capacitor C2 has the characteristic that the voltage at both ends is not easy to change suddenly, so the transient voltage of the wake-up signal when the charging gun is inserted drops from the normal power supply voltage provided by the battery 2 to the junction with the first resistor R1 and the third transistor D3 The voltages are consistent, and then the battery 2 charges the second capacitor C2 through the eighth resistor R8, so that the voltage of the wake-up signal returns to the normal power supply voltage. Therefore, the wake-up circuit 112 superimposes a small downward pulse on the wake-up signal when the charging gun is inserted, and provides input for the back-end latch chip to latch the falling edge. Similarly, when the charging gun is pulled out after charging is completed, a small upward pulse will be superimposed on the wake-up signal, but this pulse will not be recognized by the back-end latch chip.

It can be understood that the pulse generating circuit composed of the seventh resistor R7, the eighth resistor R8 and the second capacitor C2 in the wake-up circuit realizes the undershoot when the charging gun is inserted, and the overshoot when the charging gun is pulled out. 12.
