[0037] The following is a further detailed description of the specific embodiments of the present invention through the description of the embodiments with reference to the accompanying drawings. The purpose is to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate its implementation. It should be noted that the terms "first" and "second" described in this application are only used to facilitate the description of the technical solution to distinguish different components and are not intended to limit this application. To make the technical solution of the present invention clearer, the present invention is explained through the following embodiments.

[0038] The charging pile structure used in this embodiment is as follows Figure 1 As shown, a charging pile 1 is provided with a charging pile gun socket 2 on one side. A wiring harness is led out of the charging pile 1 and connected to a charging gun 3. When charging a vehicle, the charging gun 3 plugs into the vehicle charging socket. When not charging, to ensure the safety of the charging gun, the charging gun 3 plugs into the charging pile gun socket 2.

[0039] In order to standardize the use of charging guns and protect the safety of charging guns, this embodiment provides an intelligent management system for charging guns of new energy vehicles, such as Figure 2 As shown in the figure, the system includes a charging gun position detection module, a charging pile controller, a vehicle battery management module (BMS), a display screen, a user reminder module, and a billing module. The connection relationship and signal transmission between them are as follows:

[0040] The charging gun position detection module is connected to the charging pile controller and is used to detect the position of the charging gun and send it to the charging pile controller;

[0041] The vehicle battery management module (BMS) is connected to the charging pile controller to monitor the vehicle battery status and send it to the charging pile controller. In this embodiment, the vehicle battery management module (BMS) is connected to the charging pile controller via a CAN bus, which makes communication faster and more stable, thereby ensuring real-time battery status monitoring. The CAN bus is set in the charging gun as one of the charging gun lines, which is simple to lay out.

[0042] The charging pile controller is connected to the user reminder module and the display screen respectively, and is used to analyze and process the received vehicle battery status and charging gun position and send them to the display screen for display. At the same time, when the vehicle is fully charged but the charging gun position is abnormal, an alarm signal is sent to the user reminder module;

[0043] The user reminder module is used to remind the user according to the alarm signal;

[0044] The billing module is connected to the charging pile controller and is used to synchronize the vehicle battery status obtained by the charging pile controller for charging billing, and synchronize the charging gun position obtained by the charging pile controller after charging is completed for additional billing. After billing, an order is generated and sent to the display screen for display after processing by the charging pile controller.

[0045] Specifically, the charging pile controller, display screen, and user reminder module of this embodiment are arranged on the charging pile, and the vehicle battery management module BMS is arranged in the vehicle. Figure 3 As shown, the charging gun position detection module of this embodiment includes:

[0046] A power supply U1, a resistor R1, and a monitoring point U0 are provided inside the charging pile, and the monitoring point U0 is connected to the charging pile controller;

[0047] The resistor R2 and normally closed switch S1 are set on the charging gun plug;

[0048] Resistor R3 is set inside the charging pile gun socket;

[0049] Resistor R4 is provided inside the vehicle charging socket;

[0050] The power supply U1 is connected in series with the resistor R1, the monitoring point U0, the resistor R2, and the normally closed switch S1, and then to ground. Resistors R3 and R4 are also connected in parallel between the monitoring point U0 and ground. The resistances of resistors R2, R3, and R4 are unequal, i.e., R2 ≠ R3 ≠ R4. The entire charging gun position detection module has a simple structure and is easy to deploy, reducing system implementation costs.

[0051] The operating principle of the charging gun position detection module is as follows: The charging pile controller determines whether the charging gun plug is inserted into the charging pile gun socket or the vehicle charging socket based on the input voltage of the monitoring point U0, or whether the charging gun is not in its original position, that is, the charging gun is neither in the charging pile gun socket nor in the vehicle charging socket. Specifically, when the charging gun is not in its original position, the normally closed switch S1 remains normally closed, and the input voltage of U0 is the divided voltage across resistor R2; when the charging gun plug is inserted into the charging pile gun socket, the normally closed switch S1 is opened, at which point the input voltage of U0 is the divided voltage across resistor R3; when the charging gun plug is inserted into the vehicle charging socket, the normally closed switch S1 is opened, at which point the input voltage of U0 is the divided voltage across resistor R4. Since R2≠R3≠R4, the input voltage of monitoring point U0 is different in various charging gun positions. Therefore, the charging pile controller can accurately identify the charging gun position, facilitating subsequent intelligent management of the charging gun.

[0052] The charging pile controller of this embodiment adopts a microprocessor MCU, which has the advantages of high data processing efficiency, high integration and low cost. During specific implementation, the charging pile controller can also flexibly select other controllers according to actual conditions. In this embodiment, the charging pile controller converts the received car battery status and charging gun position into image data and sends it to the display screen for display. Simply put, the charging pile controller converts the digital signal composed of the car battery status and charging gun position into an analog signal and sends it to the display screen for display. At the same time, the charging pile controller determines whether charging is completed based on the car's charging status, including the vehicle's charging status, including charging time, charging power, battery power, etc. After charging is completed, the charging pile controller regards the failure of the charging gun to be unplugged from the vehicle's charging socket and the failure of the charging gun to be returned to its position as a position abnormality, and immediately sends an alarm signal to the user reminder module when an abnormality is found to remind the user to reset the charging gun position in time.

[0053] The real-time display of the car charging status on the display screen makes it easier for users to monitor the vehicle charging status; the real-time display of the charging gun position on the display screen shows whether the charging gun is returned to its position or whether it is unplugged from the vehicle charging socket, thereby reminding the user to reset the charging gun in time to a certain extent. However, the user may not notice the display information on the display screen after charging is completed. Therefore, this embodiment also provides a user reminder module to further remind the user, so that the user can pay attention to abnormal charging gun position in time.

[0054] The user reminder module of this embodiment includes a speaker connected to the charging pile controller. Upon receiving an alarm signal from the charging pile controller, the speaker is configured to emit a voice or buzzer to alert the user. Compared to display-based reminders, audio-based reminders are more effective and more easily noticed by users.

[0055] In order to further ensure that users can receive reminders in a timely manner, the user reminder module of this embodiment also includes a wireless communication device, which is connected to the charging pile controller and is used to synchronize reminders to the user's mobile device (such as a mobile phone, tablet, etc.) after receiving the alarm signal sent by the charging pile controller. Specifically, the wireless communication device of this embodiment includes a Bluetooth device, a WiFi device, and a mobile Internet device, and the Bluetooth device, WiFi device, and mobile Internet device are respectively connected to the charging pile controller. Based on the Bluetooth device or WiFi device, when the user enters the signal range of the corresponding device, if the charging pile controller finds that the position of the charging gun is abnormal after charging is completed, the charging pile controller alarm signal is automatically synchronized to the mobile device, which is suitable for alarm reminders when the user is at a short distance from the charging pile. Based on the mobile Internet device, the user's mobile device can receive the alarm signal synchronized by the charging device controller as long as it is in an online state, which is suitable for alarm reminders when the user is at a long distance from the charging pile. In summary, no matter how far the user is from the charging pile, he can receive reminders in time, so as to reset the position of the charging gun in time to protect the charging gun.

[0056] In this embodiment, the billing module includes a billing controller, which is connected to the charging pile controller and is used to generate an order after billing and send it to the display screen for display after processing by the charging pile controller. Similarly, the billing controller can also use an integrated chip such as a microprocessor MCU to improve data processing efficiency. This embodiment sets a billing controller separately in the billing module to perform billing analysis independently, without relying on the charging pile controller, thereby releasing the data processing performance of the charging pile controller, and also improving the billing analysis efficiency, ensuring that the billing analysis is rapid and accurate, and avoiding misjudgments and missed judgments. In this embodiment, the billing module synchronizes the charging gun position obtained by the charging pile controller after charging is completed for additional billing, thereby encouraging users to develop good charging habits and avoid additional costs caused by non-standard operations.

[0057] According to the intelligent management system of a new energy vehicle charging gun of this embodiment, this embodiment also proposes an intelligent management method of a new energy vehicle charging gun, such as Figure 4 As shown, the method includes:

[0058] Step S1: Obtain the vehicle battery status and charging gun position in real time and send them to the charging pile controller;

[0059] Step S2: The charging pile controller converts the vehicle battery status and charging gun position into image data in real time and sends it to the display screen for display. At the same time, if it is detected that charging is completed but the charging gun is not unplugged from the vehicle charging socket, it is considered that the charging gun position is abnormal and a timer is started. The time is recorded as T1. If T1 is greater than a preset first time threshold, an alarm signal is sent to the user reminder module.

[0060] When the charging pile controller detects that charging is completed but the charging gun is not inserted into the vehicle charging socket or the charging pile hanging gun socket, it is considered that the charging gun position is abnormal and starts timing, and the time is recorded as T2. If T2 is greater than the preset second time threshold, an alarm signal is sent to the user reminder module; after receiving the alarm signal, the user reminder module reminds the user to return the charging gun in time.

[0061] Step S3: The billing module obtains the vehicle battery status during the charging process and charges the vehicle based on the real-time charging power and charging time. It also obtains the time when the charging gun is abnormally positioned, i.e., T1+T2, and charges an additional fee. Preferably, if T1+T2 is less than a preset third time threshold, the additional fee is 0, and only the charging fee is calculated. If T1+T2 is greater than or equal to the preset third time threshold, an additional fee is charged on top of the charging fee, i.e., an overtime fee Z is calculated:

[0062] Z = X*T1+Y*T2, where X and Y represent different rates, which can be flexibly set based on actual conditions to reflect differentiated guidance on user behavior. An upper limit is also set for overtime fees.

[0063] The preset first, second, and third time thresholds can be flexibly selected based on actual circumstances during implementation. The first and second thresholds provide users with ample time to confirm the location of the charging plug, avoiding misjudgments. The third threshold, while encouraging users to develop good charging habits, fully considers the differences in user behavior and sets acceptable additional billing methods, thereby improving overall charging service satisfaction.

[0064] In summary, this embodiment effectively solves the problem of improper placement of charging guns through innovative intelligent detection of charging gun position and reasonable user reminders. It not only improves the safety and utilization efficiency of charging facilities, but also promotes the standardization of new energy vehicle charging behavior, with significant social and economic benefits.

[0065] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described method. Any non-substantial improvements made using the method concepts and technical solutions of the present invention, or any direct application of the above-described concepts and technical solutions to other situations without modification, fall within the scope of protection of the present invention.
