Description

Technical Field

[0001] This utility model relates to the field of charging piles and vehicle charging technology, specifically to an AC charging pile orderly charging control device. Background Technology

[0002] Currently, with the rapid development of electric vehicles, traditional constant current and constant voltage charging methods can no longer meet the large-scale charging demands, easily leading to charging pile overload and energy waste. Therefore, the introduction of orderly charging technology can realize intelligent scheduling and management of charging piles, improving the utilization rate and charging efficiency of charging piles.

[0003] However, some electric vehicles cannot meet the orderly charging start-stop control logic. Traditional vehicles, after stopping charging due to malfunctions, require user intervention to manually plug and unplug the charging gun to resume charging, which is time-consuming, labor-intensive, and reduces charging efficiency. Therefore, this patent proposes an electric vehicle start-stop control method based on the orderly charging CC and CP signals of an AC charging pile to solve these problems. Summary of the Invention

[0004] To address the problem that existing vehicles cannot automatically control the start and stop of the next charging cycle after charging is completed, requiring manual plugging and unplugging of the charging gun to use the charging station, this utility model provides an AC charging station orderly charging control device with multiple automatic charging functions, which solves the problem of requiring manual intervention for multiple charging cycles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An orderly charging control device for AC charging piles includes a user terminal, a cloud platform, a charging pile, and a vehicle terminal. The user terminal is used for users to log in to an operation page to control charging and power outages, and view charging information. The cloud platform includes a signal receiving unit, a signal processing unit, a data storage unit, a data transmission unit, and a signal feedback unit. The signal receiving unit receives operation commands from the user terminal and the operating status information of the charging pile. The signal processing unit filters and amplifies the information stream from the signal receiving unit. The data storage unit records the status and operation information of the user terminal and the charging pile, storing it in an Excel spreadsheet format on a daily basis for easy data retrieval and viewing by the user terminal. The data transmission unit sends and receives charging commands and status information via network signals. The charging pile includes a charging pile body and an anti-interference unit and a start-stop control unit installed within the charging pile body. The charging pile body provides charging functionality to the vehicle and sends a PWM signal to the vehicle during charging. The vehicle recognizes changes in the PWM signal parameters of the charging pile and adjusts its charging status accordingly. The anti-interference unit optimizes the transmission path for effective anti-interference of the PWM signal. The start-stop control unit controls the charging status of the vehicle by controlling the duty cycle, voltage, frequency, and on / off state of the PWM signal on any or a combination of the CP and CC signal lines connecting the charging pile body and the vehicle. The vehicle connects to the charging pile body for charging via a charging gun.

[0007] Preferably, the start-stop control unit includes a CP signal detection module, which detects the PWM signal parameters on the CP signal and transmits corresponding control commands. When the vehicle detects a change in the CP signal line state, it controls its internal resistor switch to change the charging gun state. Simultaneously, the CP signal detection module controls the CP signal line to make the vehicle recognize the charging gun as not plugged in. When the PWM signal state changes again, the CP signal detection module controls the CP signal line to make the vehicle recognize the charging gun as plugged in, thereby changing the vehicle's charging state and completing the vehicle start-stop control.

[0008] Preferably, the start-stop control unit includes a CC signal detection module, which detects the PWM signal parameters on the CC signal and transmits corresponding operation commands. When the vehicle detects a change in the state of the CC signal line, it controls its internal resistor switch to change the state of the charging gun. At the same time, the CC signal detection module controls the CC signal line to make the vehicle recognize the charging gun as not plugged in. When the PWM signal state changes again, the CC signal detection module controls the CC signal line to make the vehicle recognize the charging gun as plugged in, thereby changing the vehicle's charging state and completing the vehicle start-stop control.

[0009] More preferably, the user terminal is either a mobile phone or a tablet.

[0010] Further preferably, the user terminal also includes a login unit and a display unit; the login unit is used for users to log in to the operation page using a centrally set independent account and password; the display unit is used to display the operation pages of different modules to the user, including a charging information module, a power outage information module, and a charging power information module.

[0011] More preferably, the data transmission unit uses the 5G network transmission protocol for continuous wireless data transmission.

[0012] More preferably, the charging status of the vehicle and the charging pile includes a real-time charging status with on-state current and voltage, a charging end status, and a simulated unplugging status.

[0013] More preferably, the signal commands between the cloud platform and the charging pile include a charging start command, a charging end command, a command to send a simulated gun removal signal, a command to return a simulated gun removal signal, and a command to start charging multiple times.

[0014] The advantages of this invention compared to existing technologies are as follows: The control device can dynamically adjust the working status of the charging pile according to user needs and grid load conditions; when the grid load is high, the power supply to the charging pile can be temporarily stopped to avoid overload and energy waste; when the grid load is low, the charging pile can be started and charging services provided, optimizing charging efficiency; start-stop control can avoid grid load peaks caused by concentrated charging pile starts; through intelligent scheduling and distributed charging pile start-up times, the load of the charging piles can be smoothly distributed, reducing grid load peaks, minimizing impact on the grid, and improving grid stability; this control method can dynamically adjust the charging power according to real-time grid load conditions, avoiding energy waste and increased costs; by rationally controlling the start-stop status of the charging pile, charging can be carried out when the grid load is low, utilizing idle grid resources and reducing energy consumption and charging costs during peak periods; through intelligent scheduling and management, the utilization rate and charging efficiency of the charging pile are improved, user waiting time is reduced, and user experience is enhanced; users can more conveniently obtain charging services and choose suitable charging piles according to their own needs.

[0023] Example 1: As Figures 1 to 3 As shown:

[0024] An orderly charging control device for AC charging piles includes a user terminal 1, a cloud platform 2, a charging pile 3, and a vehicle terminal 4. The user terminal 1 is used for users to log in to the operation page to control charging and power outages, and view charging information; the user terminal 1 uses a mobile terminal such as a mobile phone or tablet. The user terminal 1 also includes a login unit 11 and a display unit 12; the login unit 11 is used for users to log in to the operation page using a centrally set independent account and password. The display unit 12 is used to display the operation pages of different modules to the user, including a charging information module 13, a power outage information module 14, and a charging power information module 15. The charging information module 13 mainly displays whether the charging gun of the charging pile is properly connected to the vehicle, and whether the charging current and charging voltage are normal. If any parameter is abnormal, the charging information module will turn gray and cannot be used normally or send charging commands. The power outage information module 14 mainly displays abnormal connection status information between the charging pile, the vehicle terminal, and the cloud platform. The charging power information module 15 mainly displays the remaining total power, total power used, current power used, voltage index, and current index under the user account.

[0025] In this embodiment, the cloud platform 2 includes a signal receiving unit 21, a signal processing unit 22, a data storage unit 23, a data transmission unit 24, and a signal feedback unit 25. The signal receiving unit 21 receives operation command information from the user terminal 1 and the operating status information of the charging pile 3. The signal processing unit 22 filters and amplifies the information stream from the signal receiving unit 21. The data storage unit 23 records the status and operation information of the user terminal 1 and the charging pile 3, storing it in a daily format in an Excel spreadsheet for easy data retrieval and viewing by the user terminal 1. The data transmission unit 24 sends and receives charging commands and status information via network signals; specifically, the data transmission unit 24 uses a 5G network transmission protocol for continuous wireless data transmission.

[0026] In this embodiment, the signal feedback unit 25 is used to receive operation commands from the user terminal 1 and directly feed back the relevant response operation information to the charging pile 3. The charging pile 3 includes a charging pile body 31 and an anti-interference unit 32 and a start-stop control unit 33 disposed within the charging pile body 31. The charging pile body 31 is used to provide charging functionality to the vehicle terminal 4 and sends a PWM signal to the vehicle terminal 4 during the charging process. The vehicle terminal 4 recognizes changes in the PWM signal parameters of the charging pile and changes its charging state accordingly. The anti-interference unit 32 is used to optimize the transmission path for effective anti-interference of the PWM signal; wherein, the anti-interference unit adopts an anti-electromagnetic interference device to eliminate electromagnetic interference: grid voltage regulation, power factor regulation sudden change interference, contactor, electromagnet, motor, transformer on / off interference. The start-stop control unit 33 controls the charging state of the vehicle terminal 4 by controlling the changes in the duty cycle, voltage, frequency, and on / off state of the PWM signal on any or a combination of the CP and CC signal lines connected between the charging pile body 31 and the vehicle terminal 4. The vehicle terminal 4 is connected for charging through the charging gun of the charging pile body 3. In this way, when the grid load is high, the power supply to the charging pile can be temporarily stopped to avoid overload and energy waste; when the grid load is low, the charging pile can be activated and charging services can be provided to optimize charging efficiency.

[0027] Among them, such as Figure 2 As shown: The charging status of the vehicle terminal 4 and the charging pile 3 includes the real-time charging status of the starting current and voltage, the charging end status, and the simulated gun disconnection status. The signal commands between the cloud platform 2 and the charging pile 3 include the charging start command, the charging end command, the command to send a simulated gun disconnection signal, the command to return a simulated gun disconnection signal, and the command to start charging multiple times. The start-stop control unit 33 includes a CP signal detection module 34, which is used to detect the PWM signal parameters on the CP signal and transmit corresponding control commands. When the vehicle terminal detects a change in the CP signal line status, it controls its internal resistor switch to change the charging gun status. At the same time, the CP signal detection module controls the CP signal line to make the vehicle terminal recognize the charging gun as not plugged in. When the PWM signal status changes again, the CP signal detection module controls the CP signal line to make the vehicle terminal recognize the charging gun as plugged in, thereby changing the vehicle's charging status and completing the vehicle start-stop control.

[0028] This embodiment primarily employs a start-stop control unit to monitor and control the opening and closing of the charging cable (CP line) to simulate the charging port status during vehicle charging. In simpler terms, the user sends a command to the cloud platform, which then controls the charging pile to disconnect the CP line from the vehicle interface. This causes the vehicle to perceive or detect a non-plugged state, thus changing the vehicle's charging status and achieving charging without requiring manual plugging and unplugging. In this way, the control device avoids peak grid load caused by concentrated charging pile startups. By intelligently scheduling and distributing the startup times of charging piles, the load on charging piles can be smoothly allocated, reducing the impact on the grid and improving grid stability. Simultaneously, the start-stop control method can dynamically adjust the charging power based on real-time grid load conditions, avoiding energy waste and increased costs. By rationally controlling the start-stop status of charging piles, charging can occur when the grid load is low, utilizing idle grid resources and reducing energy consumption and charging costs during peak periods.

[0029] Example 2: Figure 3 As shown:

[0030] This embodiment is similar to the technical solution of Embodiment 1, except that: an AC charging pile orderly charging control device includes a start-stop control unit 33 comprising a CC signal detection module 35. The CC signal detection module 35 detects the PWM signal parameters on the CC signal and transmits corresponding operation commands. When the vehicle 4 detects a change in the state of the CC signal line, it controls its internal resistor switch to change the state of the charging gun. Simultaneously, the CC signal detection module 35 controls the CC signal line to make the vehicle recognize the charging gun as not plugged in. When the PWM signal state changes again, the CC signal detection module 35 controls the CC signal line to make the vehicle recognize the charging gun as plugged in, thereby changing the vehicle's charging state and completing the vehicle start-stop control. This embodiment mainly uses the start-stop control unit to monitor and control the opening and closing of the CC line to simulate the plugged-in state of the vehicle during charging. In simpler terms, the user sends a command to the cloud platform, which then controls the charging pile to disconnect the CC line connected to the vehicle interface, causing the vehicle to perceive or detect the charging gun as not plugged in, thereby changing the vehicle's charging state and completing the vehicle's start-stop charging operation without requiring manual repeated plugging and unplugging.

[0031] Example 3: As Figure 3 As shown:

[0032] This embodiment is similar to the technical solution of Embodiment 1, except that: an AC charging pile orderly charging control device, wherein the start-stop control unit 33 includes a CP signal detection module 34 and a CC signal detection module 35. The CP signal detection module 34 is used to detect the PWM signal parameters on the CP signal and transmit corresponding control commands. The CC signal detection module 35 is used to detect the PWM signal parameters on the CC signal and transmit corresponding operation commands. When the vehicle 4 simultaneously detects a change in the state of the CC and CP signal lines, it controls its internal resistor switch to change the state of the charging gun. At the same time, the CP signal detection module 34 and the CC signal detection module 35 control the CP and CC signal lines to make the vehicle recognize the charging gun as not plugged in. When the PWM signal state changes again, the CP signal detection module 34 and the CC signal detection module 35 control the CC signal line to make the vehicle recognize the charging gun as plugged in, thereby changing the vehicle's charging state and completing the vehicle start-stop control. This embodiment mainly uses the start-stop control unit to simultaneously monitor and control the opening and closing of the CP and CC lines to simulate the plugged-in state of the vehicle during charging. In simpler terms, the user sends a command to the cloud platform, which then controls the charging pile to simultaneously disconnect the CC and CP lines connected to the vehicle interface. This causes the vehicle to perceive or detect that the charging pile is not plugged in, thereby changing the vehicle's charging status and completing the charging operation by controlling multiple starts and stops to avoid manual plugging and unplugging.
