[0035] Figure 3 It is a structural block diagram of a charging pile in one embodiment of the present invention. DETAILED DESCRIPTION

[0036] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0037] Unless explicitly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising”, etc., will be understood to include the stated elements or components but not to exclude other elements or components.

[0038] Please refer to Figure 1 FIG. 1 is a schematic diagram of an exemplary implementation scenario of a charging method provided in one embodiment of the present invention. Figure 1 The implementation scenario shown includes a user terminal 101, an operation and maintenance server 102, and a charging pile 103 connected via network communication. The user terminal 101 is installed with an APP that can be used to access the operation and maintenance server 102, and the operation and maintenance server 102 can perform operation and maintenance management on the charging pile 103.

[0039] The network may be a wireless channel such as the second generation mobile communication technology (2G), the third generation mobile communication technology (3G), the fourth generation mobile communication technology (4G), etc. The wireless channel may also be a wireless communication channel implemented by one or more of the future fifth generation mobile communication technology (5G), cellular-based narrowband Internet of Things (NB-IoT), and future newly defined air interface technologies, etc., and this embodiment is not limited thereto.

[0040] The user terminal 101 may be a mobile terminal such as a smart phone, a tablet computer, a laptop computer, etc. The operation and maintenance server 102 may be an independent physical server, or a server cluster or a distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDN), and big data and artificial intelligence platforms.

[0041] The user can input the license plate information through the APP in the user terminal 101 and upload the license plate information to the operation and maintenance server 102. The image acquisition device of the charging pile can capture the license plate image of the vehicle to identify and obtain the license plate information of the vehicle and upload it to the operation and maintenance server 102. The operation and maintenance server 102 can determine whether the vehicle is an electric vehicle based on the license plate information of the vehicle; if the vehicle is an electric vehicle, the operation and maintenance server 102 further determines whether the license plate information of the vehicle is consistent with the license plate information input by the user; if the license plate information of the vehicle is consistent with the license plate information input by the user, the operation and maintenance server 102 turns on the charging pile 103 to charge the vehicle.

[0042] Please refer to Figure 2 The figure is a flow chart of a charging method in one embodiment of the present invention. The document image correction method specifically comprises the following steps:

[0043] S201: Acquire the vehicle's license plate information and the license plate information input by the user.

[0044] In an exemplary embodiment, after a vehicle enters a parking space of a charging pile, an image capture device of the charging pile may be used to capture an image of the vehicle's license plate to identify and obtain the license plate information in the image of the license plate.

[0045] Specifically, the camera of the charging pile can capture the image of the vehicle license plate at the parking space of the charging pile, and use image processing and recognition technology to convert the characters on the license plate into computer-readable text. This method requires the use of professional OCR (Optical Character Recognition) software or algorithms to convert the license plate image captured by the camera into text information for the recognition and management of license plate number and other information.

[0046] The license plate information of vehicles at the charging pile parking space can also be identified by reading the license plate recognition device (LPR). The license plate recognition device can use a camera to capture the license plate image of the vehicle, then automatically perform license plate recognition, and send the license plate information to the operation and maintenance server for management and processing.

[0047] In an exemplary embodiment, an information input interface may be provided based on a user's charging request, and license plate information input by the user in the information input interface may be obtained.

[0048] Specifically, the user can initiate a charging request through the APP installed in the user terminal. The operation and maintenance server responds to the user's charging request and provides an information input interface in the user terminal for the user to input information. The user can enter license plate number, telephone number and other information in the information input interface. After the user completes the information input, the information can be sent to the operation and maintenance server.

[0049] S202: Determine whether the vehicle is an electric vehicle based on the license plate information of the vehicle.

[0050] In an exemplary embodiment, whether the vehicle is an electric vehicle may be determined based on the length of the license plate number and / or the color of the license plate of the vehicle.

[0051] It should be noted that the length and color of the license plate numbers of electric vehicles and fuel vehicles are usually different. For example, the length of the license plate number of an electric vehicle is 6 digits and the color is green, while the length of the license plate number of a fuel vehicle is 5 digits and the color is blue or yellow. Therefore, the length and / or color of the license plate number of a vehicle can be used to determine whether it is an electric vehicle.

[0052] In an exemplary embodiment, if the vehicle is not an electric vehicle, an alarm message is sent to the user to remind the user that the charging pile parking space is for electric vehicles that need to be charged, and the user may be asked to move the non-electric vehicle parked at the charging pile parking space to avoid occupying the charging pile parking space.

[0053] The aforementioned alarm information can be issued through an audible and visual alarm, which can issue a voice prompt alarm through a built-in speaker and emit bright light through a built-in LED light or flash light to serve as a warning.

[0054] S203: If the vehicle is an electric vehicle, determine whether the license plate information of the vehicle is consistent with the license plate information input by the user.

[0055] It should be noted that if the vehicle is determined to be an electric vehicle based on the license plate information, it is necessary to further confirm whether the license plate information of the vehicle is consistent with the license plate information input by the user.

[0056] In an exemplary embodiment, if the license plate information of the vehicle is inconsistent with the license plate information input by the user, the user may be prompted to re-enter the license plate information.

[0057] S204: If the license plate information of the vehicle is consistent with the license plate information input by the user, turn on the charging pile to charge the vehicle.

[0058] It should be noted that after turning on the charging pile, the user may be prompted to remove the charging gun of the charging pile and plug the charging head of the charging gun into the charging port of the vehicle to charge the vehicle.

[0059] In an exemplary embodiment, after the charging pile is turned on, it can be determined whether the vehicle is a vehicle requiring charging based on the current of the charging gun of the charging pile; if the vehicle is a vehicle not requiring charging, the user is prompted to move the vehicle within a predetermined time; if the vehicle is not moved within the predetermined time, the vehicle is locked.

[0060] It should be noted that after the charging pile is turned on, if there is no current flowing through the charging gun within a certain period of time, it can be considered that the vehicle parked in the charging pile parking space at this time is a vehicle without charging requirements and may occupy the parking space. At this time, the user can be prompted to move the vehicle within the preset time. If the vehicle is not moved within the preset time, the vehicle can be locked by controlling the intelligent ground lock, thereby playing the role of warning the vehicle occupying the charging pile parking space.

[0061] In an exemplary embodiment, during the charging process of the vehicle, it can be determined whether the battery pack of the vehicle is fully charged; if the battery pack of the vehicle is fully charged, the full charge information is fed back to the user terminal.

[0062] It should be noted that the charging pile can determine whether the vehicle's battery pack is fully charged by measuring the voltage and current of the battery pack. When the battery pack voltage and current reach a certain level, the charging pile will automatically stop charging to avoid overcharging or over-discharging. The charging pile will record the initial voltage and current of the battery pack when charging starts, and then calculate the charging status based on the charging time and the current voltage and current. When the voltage and current begin to decrease and reach a certain threshold, the charging pile will think that the battery pack is full and then automatically stop charging. At this time, the charging pile will send a notification to the user that charging is complete, and will feed back the full power information to the user terminal through APP or SMS, informing the user that the user can disconnect the charging gun and take out the vehicle.

[0063] In an exemplary embodiment, it is possible to determine in real time whether the vehicle charging process is abnormal during the charging process; if the charging process is abnormal, the charging function of the charging pile is turned off, and the abnormal information is fed back to the user terminal and the charging pile service end (operation and maintenance server) to remind the user and the charging pile equipment manufacturer to promptly maintain and handle the abnormal situation.

[0064] It should be noted that whether the charging process is abnormal can be determined based on the current situation. If the current suddenly changes or jumps during charging, it may mean that there is a problem with the charging line or connector, or that the plug between the charging pile and the electric car is poorly contacted or loose. If the current continues to fluctuate or oscillate during charging, it may mean problems such as increased internal resistance of the battery, aging of the battery, and excessive temperature. If the current is abnormally high or low during charging, it may mean that the charging pile or charging line is faulty or the charging equipment is not compatible with the vehicle, or there may be a problem with the battery system. If the current continues to change slowly during charging, it may mean that the charging gun is overheating and other situations.

[0065] In an exemplary embodiment, an image of the charging gun of the charging pile can be captured by an image capture device based on the charging pile; based on the charging gun image, it is determined whether the charging gun is abnormal; if the charging gun is abnormal, the abnormal information is fed back to the charging pile service end to notify the charging pile equipment manufacturer to promptly maintain and handle the abnormal situation.

[0066] It should be noted that the abnormal conditions of the charging gun include abnormal conditions such as the wiring harness of the charging gun being entangled, knotted, or damaged. After the image acquisition device acquires the image of the charging gun of the charging pile, it can identify and analyze the image of the charging gun based on image recognition technology to determine whether the charging gun has the aforementioned abnormal conditions.

[0067] To sum up, the charging method provided by the present invention can obtain the license plate information of the vehicle and the license plate information input by the user, first determine whether the vehicle is an electric car based on the license plate information, and after determining that the vehicle is an electric car, further determine whether the license plate information of the vehicle and the license plate information input by the user are consistent. If the license plate information is consistent, the vehicle can be considered to be a charging-demand vehicle, and then the charging pile is turned on to charge the vehicle, which can avoid vehicles that do not need to be charged occupying the charging pile.

[0068] Please refer to Figure 3 As shown, based on the same inventive concept as the aforementioned charging method, an embodiment of the present invention further provides a charging pile 300 , which includes an acquisition module 301 , a first determination module 302 , a second determination module 303 and a charging module 304 .

[0069] Among them, the acquisition module 301 is used to obtain the license plate information of the vehicle and the license plate information input by the user. The first determination module 302 is used to determine whether the vehicle is an electric vehicle based on the license plate information of the vehicle. The second determination module 303 is used to determine whether the license plate information of the vehicle is consistent with the license plate information input by the user when the vehicle is determined to be an electric vehicle. The charging module 304 is used to turn on the charging function of the charging pile to charge the vehicle when the license plate information of the vehicle is consistent with the license plate information input by the user.
