[0025] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] In order to solve the current problem that the charging pile is still consuming power and energy during the waiting period, thereby wasting a lot of electric energy, the utility model provides a charging system for the charging pile, which improves the circuit of the existing charging pile so that it can be disconnected from the external 220V AC power supply used for charging during the waiting period, thereby greatly reducing the power consumption of the charging pile during the waiting period. Figure 1 and Figure 2 As shown, the charging system includes:

[0027] A signal input module 1 for obtaining a first signal input by a user, and outputting a second signal to the control module 2 for a certain period of time. When the user needs to use it, a first signal can be input into the circuit of the charging system by touching a specific key, and the signal input module 1 processes the first signal to obtain a second signal that can be read by the control module 2; a control module 2 for outputting a third signal with a certain voltage value to the communication interface module when the second signal is detected, the third signal is generally a 12V current signal, and continuously sending the third signal when receiving the fourth signal fed back by the communication interface module 3. When the charging gun is plugged into the charging interface of the charged object, the third signal is output and connected to the Cam communication application device and Bms battery management system of the charged object such as the car, and the communication interface module 3 receives the Cam The communication interface module 3 receives the signal fed back by the communication application device and the BMS battery management system, and enables the communication interface module 3 to generate a fourth signal. The fourth signal is generally a 6V or 4V current signal. After the fourth signal is obtained by the control module 2, the control module 2 can also continuously send the third signal, so that the AC charging circuit of the charging module 4 is connected to the charged object for charging; when the third signal sent by the control module 2 is detected, data is exchanged with the charged object and a fourth signal is generated, and the fourth signal is sent to the communication interface module 3 of the control module 2, so that the user does not need to repeatedly input the first signal to finally generate the third signal. During the charging process, the third signal will be continuously generated according to the feedback of the fourth signal; when the third signal sent by the control module 2 is detected, the communication interface module 3 of the control module 2 is used to generate the fourth signal and the fourth signal is sent to the communication interface module 3 of the control module 2. When the third signal is received, the charging module 4 controls the AC charging circuit to be connected with the AC power supply for charging. There is generally a switch in the charging module 4. Under the action of the third signal, the AC charging circuit is connected with the AC power supply for charging. The AC power supply then allows the AC power to enter the charged object through the circuit plugged into the charged object, thereby completing the charging process. Through the above structure, the AC power supply can be disconnected during the waiting period of the charging pile, so that the AC power supply is not consumed, and only the electric energy generated by the battery carried by the system itself is consumed. The battery is only used to maintain the operation of the internal chip, and the power consumption is extremely small. Its power consumption is less than 1 watt, which is about 0.075 watts, that is, 75 milliwatts, which is tens of thousands of times the power consumption of the prior art.

[0028] The signal input module 1 realizes the purpose of converting the first signal input by the user into a second signal that can be read by the control module 2. A circuit of the signal input module 1 is provided below for illustration. The signal input module 1 includes a third chip U3 for signal processing. Pin 1 of the third chip U3 is connected in series with a resistor R6 and a touch switch J1 for generating a first signal. Pin 5 of the third chip U3 is used to output a second signal. When the user presses his finger on the tempered glass panel, the touch switch J1 will give a first signal. After pin 1 of the third chip U3 receives the first signal, pin 5 of the third chip U3 will output a high potential. When the touch switch J1 is touched again, pin 5 of the third chip U3 will output a low potential, thereby continuously outputting a second signal with a different potential to the control module 2. The model of the third chip U3 can be ADA05F. In this way, each time the user touches the touch switch J1, the control module 2 will send a corresponding control signal according to the received second signal.

[0029] The control module 2 is used to process the received second signal and fourth signal. The structure of the control module 2 is disclosed below. The control module 2 includes a first chip U1 whose pin 3 is connected to pin 5 of the third chip U3, pin 4 of the first chip U1 is used to output the third signal, pin 3 of the first chip U1 is used to receive the second signal, pins 2 and 7 of the first chip U1 are used to receive the fourth signal, and the model of the first chip U1 can be PY32F002AL15S, thereby realizing signal transmission between the second signal, the third signal and the fourth signal.

[0030] The charging module 4 determines whether to connect to the external 220V AC power according to whether the third signal exists. The circuit structure of the charging module 4 is provided below. The charging module 4 includes a resistor R7, a capacitor C9, a resistor R14, a mode tube Q1, a diode D9, a power supply CZ1, a relay J2, and a terminal block CZ2, which are sequentially arranged between the 4th and 8th pins of the first chip U1. The interface 1 of the terminal block CZ2 is connected to the charging power supply, and the interface 2 of the terminal block CZ2 is connected to the charging interface of the charged object. When the 4th pin of the first chip U1 outputs the third signal, the mode tube Q1 is turned on, thereby controlling the relay J2 to connect the 220V AC power to the charging gun head connected to the charged object, so as to charge the charged object.

[0031] The communication interface module 3 is used to connect and communicate with the Cam communication application device and the Bms battery management system of the charged object through the charging gun head. The communication interface module 3 will receive the feedback signal from the Cam communication application device and the Bms battery management system, and enable the communication interface module 3 to generate a fourth signal. The circuit structure of the communication interface module 3 is further described below. The communication interface module 3 includes a capacitor C13, a resistor R8, a resistor R9, a voltage regulator tube D10, a resistor R10, a voltage regulator tube TVS1 and a terminal block CZ4 which are sequentially connected between the 7th and 8th pins of the first chip U1. During the waiting period of the charging pile, the terminal block CZ4 and the terminal block CZ5 mentioned below are two sockets for giving signals inside the two charging guns. The terminal block CZ4 is A The 12V socket of the gun, the terminal block CZ5 is the 12V socket of the B gun. The internal changes reflect that after the control voltage sampling voltage of the two gun heads comes out, through the setting of each voltage regulator tube and resistor in the communication interface module 3, it has the function of bidirectional pulse absorption to prevent the large pulse arc voltage during charging from entering the first chip U1 through the circuit of the communication interface module 3 in the charging gun, thereby protecting the first chip U1 from being broken down and damaged.

[0032] Two communication interface modules 3 can be set on the first chip U1. The circuit diagram of another communication interface module 3 is published below. The communication interface module 3 includes a capacitor C14, a resistor R11, a resistor R12, a voltage regulator D11, a resistor R13, a voltage regulator TVS2 and a terminal block CZ5 which are sequentially connected between pins 2 and 8 of the first chip U1.

[0033] In order to facilitate data interaction between users and the charging pile, it is generally necessary to set up a display module 5. In order to enable the display module 5 to achieve the power saving effect synchronously, the display module 5 includes a display screen terminal socket CZ6. A resistor R15, a mode tube Q2 and a power supply CZ8 are connected between the display screen terminal socket CZ6 and the 5th pin of the first chip U1. Therefore, after the first chip U1 receives the second signal, it will also send an electrical signal from its 5th pin to turn on the mode tube Q2, and then the display screen will be powered on and lit up through the display screen terminal socket CZ6. When charging is completed, the first chip U1 will no longer output an electrical signal, and the display screen will be turned off within a certain period of time. This time can be set independently, such as 10s.

[0034] The power module 6 is used to supply power to various components that require electricity to drive, such as the first chip U1, so that they can keep running under the action of a small current to save energy to the greatest extent. The power module 6 includes capacitor C12, capacitor C11, capacitor C8, capacitor C5, capacitor C4, resistor R4, resistor R5, coil L1, capacitor C3, second chip U2, resistor R3, capacitor C2, capacitor C1, resistor R01, resistor R1, auxiliary power supply CZ7 and resistor R2, which are connected in sequence to pin 1 of the first chip U1, so that the circuit of the charging system maintains low power consumption operation, and the relay J2 is automatically configured to charge only when charging.
