Description

Technical Field

[0001] The present invention relates to the field of charging piles, and in particular to a method and system for preventing mis-plugging and continuous charging of an AC charging pile for a two-wheeled electric vehicle. Background Art

[0002] With the popularization of electric vehicles, especially the widespread use of two-wheeled electric vehicles, various types of public and commercial charging facilities have developed rapidly. Existing two-wheeled electric vehicle AC charging piles usually complete charging control through QR code scanning payment methods. Users can scan the QR code on the charging pile with their mobile phones to select the charging port and pay for charging. However, in the prior art, charging piles often encounter a problem that bothers users during operation: after the user scans the code and pays, if the charging plug is accidentally or maliciously unplugged during the charging process, the system cannot stop charging immediately, which will cause the user to continue to be charged without actually using electricity, causing economic losses. This phenomenon occurs frequently in daily life, especially in high-frequency use environments such as public places and communities, and is prone to cause unnecessary disputes and conflicts.

[0003] To solve this problem, some current charging pile systems periodically detect charging time and power status to determine whether there is a charging disconnection. However, the existing technology does not have sufficient accuracy in identifying charging disconnection, especially in the trickle stage when charging is about to end. The natural drop in power can easily cause the system to misjudge it as a charging interruption, which in turn triggers unnecessary reminders or erroneous operations. In addition, some solutions in the existing technology are complex, involving a large number of hardware upgrades and system modifications, which increases the manufacturing and maintenance costs of charging piles and is not conducive to widespread promotion. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a method and system for preventing accidental unplugging and continuous billing for an AC charging pile for a two-wheeled electric vehicle, which can accurately identify situations where the plug is accidentally or maliciously unplugged during charging, and respond in time without affecting the user's normal charging, thereby stopping unnecessary billing. This is a problem that needs to be urgently solved in the current technical field.

[0005] The present invention is realized by the following technical scheme: a method for preventing mis-plugging and continuous charging for a two-wheeled electric vehicle AC charging pile, comprising the following steps:

[0006] Step 1: The user selects an idle charging port by scanning the QR code. The system receives the scan signal and starts the charging process.

[0007] Step 2: The charging controller detects the charging power in real time. When the charging power is lower than a preset threshold, it is determined that the plug is unplugged.

[0008] Step 3: When the charging time is in the first 2 / 3 of the set charging time and the power is continuously lower than 20W for more than the set time threshold, the system sends an abnormal reminder to the user terminal through the remote communication module;

[0009] Step 4: The user confirms the status of the charging plug within the scheduled time. If the user fails to confirm or confirms that the charging is abnormal, the system automatically stops charging and billing, and refunds the remaining unused charging fee;

[0010] Step 5. If the charging power returns to normal, continue charging until the set charging time is completed.

[0011] As a preferred technical solution, the preset power threshold is 20W and the detection time is 20 seconds.

[0012] As a preferred technical solution, the reminder message sent by the remote communication module includes a notification of abnormal charging status and a prompt to remind the user to confirm within a set time.

[0013] As a preferred technical solution, when the charging time enters the last one-third of the set charging time, the system does not make an abnormal judgment to avoid misjudgment during trickle charging.

[0014] The present invention provides a continuous charging system for preventing mis-plugging of an AC charging pile for a two-wheeled electric vehicle, the system comprising:

[0015] A QR code scanning module, used to receive a user's selection of an idle charging port by scanning a QR code;

[0016] A charging controller, used to receive the code scanning signal and control the opening and closing of the AC charging port;

[0017] Charging power detection module, used to monitor charging power changes in real time;

[0018] An abnormality reminder module is connected to the charging power detection module and the remote communication module, and triggers an abnormality reminder when the charging power is continuously lower than a preset value;

[0019] The billing module calculates the charging fee based on the charging time selected by scanning the code and the real-time power change;

[0020] The remote communication module is used to push a reminder message to the user terminal when an abnormal charging power is detected.

[0021] As a preferred technical solution, the charging power detection module is provided with a power threshold detection unit, which triggers an abnormal reminder when the power is continuously lower than 20W.

[0022] As a preferred technical solution, the abnormal reminder module sends a message reminder to the user's mobile terminal through the remote communication module, including text messages, application push or email.

[0023] As a preferred technical solution, the billing module dynamically adjusts the user's charging fee according to the real-time detected charging power, and refunds the unused fee when charging is completed or abnormally stopped.

[0024] As a preferred technical solution, a storage module is also included to store the duration of each charging, power changes and user operation records.

[0025] As a preferred technical solution, the charging controller can communicate with a remote server via a wireless network to support remote maintenance and data management functions.

[0026] The beneficial effects of the present invention are as follows: by real-time monitoring of the charging power, the present invention can promptly detect an abnormal drop in the charging power when the charging plug is accidentally or maliciously unplugged, and automatically trigger an abnormal reminder to prevent the user from continuing to be charged without actually charging, thereby effectively recovering the user's economic losses.

[0027] The present invention pushes charging status updates in real time through the system background during the charging process, and the user can remotely monitor the charging situation to avoid being unaware of abnormalities in the charging process, thereby improving the safety of the charging service and the user's satisfaction.

[0028] By setting reasonable power thresholds and detection durations, especially when charging is about to end (such as the trickle charging stage), the system can intelligently avoid misjudgments due to natural power drops, ensuring that the user's charging experience is not interrupted and reducing unnecessary reminders or interference.

[0029] The control algorithm of the present invention is simple and easy to implement. It does not require large-scale hardware upgrades to existing charging piles and can be achieved only through optimization of software and control systems. It has a low implementation cost and is easy to promote and apply on a large scale. It is particularly suitable for scenarios of community and commercial two-wheeled electric vehicle charging piles.

[0030] The present invention provides the user with an option to select whether to enable the anti-misplugging reminder function, so that the system can be flexibly adjusted according to user needs, avoiding the inconvenience caused to some users by the misplugging reminder function. At the same time, the present invention also provides a buffer time within half an hour after power failure for users to confirm the status of the plug, further enhancing the flexibility of the system. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0032] Figure 1 It is a system principle diagram of the present invention. DETAILED DESCRIPTION

[0033] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0034] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0035] The present invention relates to a method and system for preventing mis-plugging and continuous charging of AC charging piles for two-wheeled electric vehicles. First, the user selects an idle charging port by scanning a QR code, and the system receives the signal scanned by the user and starts the charging process. During the charging process, the system monitors the charging power in real time through a charging controller to ensure that charging is carried out normally.

[0036] When the charging power is lower than the preset threshold, the system will determine that the plug is unplugged or an abnormal situation occurs. According to a preferred embodiment of the present invention, the preset power threshold is 20W. When the charging power is continuously lower than 20W and the detection time exceeds 20 seconds, the system will trigger an abnormal judgment.

[0037] During the charging process, if the charging time is in the first 2 / 3 of the total charging time set by the user, and the power continues to be lower than 20W for more than the set time threshold, the system will send an abnormal reminder to the user terminal through the remote communication module. This reminder message not only contains a notification of abnormal charging status, but also prompts the user to confirm within the set time to ensure that the user can understand the charging status in time and take necessary operational measures.

[0038] After receiving the reminder, the user can confirm the status of the charging plug within the scheduled time. If the user fails to confirm in time, or confirms that the charging is abnormal, the system will automatically stop charging and stop billing, and refund the remaining unused charging fee to the user. This mechanism effectively avoids the user's additional cost loss due to the plug being unplugged. If the charging power returns to normal after the abnormal reminder, the system will continue charging for the remaining time until the set charging time is completed.

[0039] In the implementation of the present invention, in order to avoid misjudgment caused by the natural decrease in power in the trickle charging mode, the system will no longer make abnormal judgments when the charging time enters the last third of the set charging time. This design can ensure that the system will not misjudge abnormalities due to low power when charging is nearing the end, thereby further improving the user experience.

[0040] The present invention also includes an anti-misplugging continuous billing system. The system consists of multiple functional modules, including a QR code scanning module, a charging controller, a charging power detection module, an abnormal reminder module, a billing module and a remote communication module. The QR code scanning module is used to receive the charging port signal selected by the user after scanning the code to start the charging process. The charging controller is used to receive the scanning signal and control the corresponding charging port to open or close. The function of the charging power detection module is to monitor the power changes in real time during the charging process. When the power is continuously lower than the preset value, the charging power detection module will trigger an abnormal reminder and notify the abnormal reminder module to take corresponding measures.

[0041] The abnormal reminder module communicates with the user's terminal through the remote communication module. When the charging power detection module finds that the charging power is continuously lower than 20W, the abnormal reminder module will send a message reminder to the user's mobile terminal through the remote communication module, including SMS, application push or email, etc., to ensure that the user can receive the notification in time. The user can confirm after receiving the reminder, and the system will adjust the subsequent charging operation according to the user's feedback.

[0042] In terms of billing, the billing module dynamically calculates the charging fee based on the charging time selected by the user when scanning the code and the real-time detected charging power. If an abnormality occurs during the charging process and the charging is stopped, the system will refund the unused fee based on the remaining time. This billing method ensures that the user's fees are transparent and reasonable when charging is abnormal or stopped early.

[0043] In order to record the process of each charging, the system also includes a storage module to store the duration of each charging, power changes and user operation records. These data can be used for subsequent analysis and maintenance to improve the overall reliability of the system.

[0044] In addition, the charging controller can also communicate with the remote server through a wireless network to support remote maintenance and data management functions. The remote server can receive the system's working status in real time and perform remote maintenance on the system as needed, further improving the system's operability and ease of maintenance.

[0045] Through this implementation mode, the present invention not only solves the problem of continuous billing due to accidental unplugging of the AC charging pile of the two-wheeled electric vehicle, but also optimizes the user experience, and has high practicality and promotion value.

[0046] like Figure 1 As shown, the structural design of the present invention is the same as the structure of the two-wheeled electric vehicle AC charging pile on the market. A centralized charging controller controls multiple charging ports. After the customer scans the code, he selects the corresponding idle charging port. After the customer pays, the controller opens the corresponding charging port to start charging.

[0047] The present invention is mainly a solution to the problem of continuous billing for preventing mis-pulling of AC charging piles for two-wheeled electric vehicles. The customer scans the code to pay and chooses to charge for N hours. The charging controller starts charging timing and calculates the charging power in real time. At present, the power of chargers on the market is mostly above 100W. If the charging power is continuously lower than 20W (considering the detection error) within 20 seconds of charging within N*2 / 3 hours, it is considered that the charging is disconnected. It is necessary to push the charging disconnection reminder to the customer background through the charging controller, and let the customer go to the site within half an hour to confirm whether the charging is normal. If the customer confirms that the charging is normal within half an hour, the charging can continue. Otherwise, the charging is disconnected and the billing is stopped. The customer prepaid the charging fee and the charging fee for the remaining time is returned in the original way. When charging within N*2 / 3 hours to N hours, due to the charging characteristics at this time, the trickle charging mode may be entered. At this time, the charging power may be relatively small. In order to prevent misjudgment, the AC charging pile anti-mispulling judgment is not performed at this time to avoid customer troubles caused by misjudgment.

[0048] The present invention provides customers with a solution to the problem of continuous billing during the prevention of accidental unplugging of an AC charging pile. When a customer scans a code to charge, the customer needs to choose whether to need a reminder to prevent the charging pile from being accidentally unplugged, so as to avoid some customers being troubled by the reminder. If the customer does not need a reminder, scanning the code will directly open the charging interface until the billing ends.

[0049] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
