Description

Technical Field

[0001] The present disclosure relates to the field of charging technology, and in particular to a vehicle charging method, a vehicle charging device, an electronic device, and a storage medium. Background Art

[0002] With the popularity of electric vehicles, the intelligentization of charging infrastructure has become one of the key factors in improving user experience. In the existing electric vehicle charging technology, a common solution is that the charging pile triggers the vehicle's charging port cover to open automatically by transmitting a broadcast signal. Although this solution is simple and easy to implement, there is a significant problem in practical applications: when multiple vehicles are parked at the same charging station, the broadcast signal emitted by the charging pile will be received by all vehicles. Since the broadcast signal does not have a one-to-one recognition capability, all vehicles that receive the signal will automatically open the charging port cover, which will cause vehicles that do not need to open the cover to trigger the cover to open by mistake.

[0058] Some embodiments of the present disclosure will be described in detail here, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. Various changes, modifications and equivalents of the methods, devices and / or systems described herein will become apparent after understanding the present disclosure. For example, the order of operations described herein is merely an example and is not limited to those orders set forth herein, but can be changed as becomes apparent after understanding the present disclosure, except for operations that must be performed in a specific order. In addition, for clarity and brevity, descriptions of features known in the art may be omitted.

[0059] The embodiments described in some embodiments of the present disclosure below do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0060] The following describes a vehicle charging method, a vehicle charging device, an electronic device, and a storage medium proposed in embodiments of the present disclosure with reference to the accompanying drawings.

[0061] Figure 1 is a flow chart of a vehicle charging method according to an embodiment of the present disclosure.

[0062] It should be noted that the embodiments of the present disclosure are illustrated by an example in which the vehicle charging method is configured in a vehicle charging device. The vehicle charging device can be applied to any electronic device so that the electronic device can perform a vehicle charging function.

[0063] The electronic device may be any device with computing capabilities, for example, a personal computer, a mobile terminal, a server (or cloud), etc. The mobile terminal may be, for example, a vehicle-mounted device, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, or other hardware device with various operating systems, touch screens, and / or display screens, such as a charging pile. The embodiments of the present disclosure are described by taking the electronic device as a charging pile as an example.

[0064] like Figure 1 As shown, the vehicle charging method of the embodiment of the present disclosure includes:

[0065] S1, in response to a vehicle parking in a charging parking space, performing license plate recognition on the vehicle to obtain the license plate information of the vehicle.

[0066] In this step, the charging pile detects whether a vehicle is parked in the charging space by installing an infrared sensor, an ultrasonic sensor, a geomagnetic sensor or other sensors on the charging pile; and / or, by installing a camera on the charging pile to detect whether a vehicle is parked in the charging space.

[0067] When the sensor and / or camera detects that the vehicle is parked in the charging parking space, the camera is triggered to capture an image of the vehicle. The camera can be set to capture one or more images immediately after detecting that the vehicle is parked, and the captured images are stored in a local storage device or a cloud server. Then, the captured images are preprocessed, including image cropping, grayscale, binarization, etc., and then image processing algorithms (such as edge detection, contour extraction, etc.) are used to locate the license plate area in the image, and the located license plate area is further divided into individual characters. Optical character recognition OCR (Optical Character Recognition) technology or deep learning models (such as convolutional neural networks CNN (Convolutional Neural Network)) are used to recognize each character, and finally the complete license plate information is obtained. The recognized license plate information can also be verified to ensure that its format and length meet the specifications.

[0068] Finally, the vehicle's license plate information is extracted from the recognition results and stored in a local database or cloud server.

[0069] S2, in response to detecting that there is a charging intention at the charging parking space, broadcasting a cover opening request signal including the license plate information.

[0070] In order to accurately determine whether there is a charging intention at the charging parking space, after extracting the vehicle's license plate information, the charging pile can use the following three methods to determine whether there is a charging intention at the charging parking space:

[0071] In the first method, the charging pile continuously monitors the status of the charging gun thereon. If it is detected that the charging gun on the charging pile at the charging parking space is pulled out, it is determined that there is a charging intention at the charging parking space.

[0072] In the second method, the charging pile maintains a charging state machine inside to reflect the current state of the charging pile in real time, including idle state, waiting to be charged state and charging state. The charging pile will continuously monitor the changes of this state machine. If it detects that the charging state of the charging pile at the charging parking space switches from idle state to waiting to be charged state, it is determined that there is a charging intention at the charging parking space.

[0073] The third method is to further determine the type of vehicle based on the vehicle's license plate information combined with vehicle identification technology. When the type of the vehicle is determined to be a target type, such as an electric vehicle, a plug-in hybrid vehicle, or a vehicle with a charging function, continue to monitor whether the vehicle state is the target state, such as whether it is in a stopped state or a locked state. If the vehicle state is detected to be the target state, continue to detect the duration of the target state, and when the duration is greater than or equal to a set duration threshold (the set duration threshold can be set according to actual needs), determine that a charging intention is detected at the charging parking space.

[0074] After confirming that there is a charging intention at the charging parking space, the charging pile will construct an opening request signal containing the license plate information and broadcast the signal through the selected set frequency band. This opening request signal can be transmitted using a variety of wireless communication technologies, including but not limited to Bluetooth broadcast signals, radio frequency broadcast signals, Wi-Fi signals, and NFC signals.

[0075] S3, in response to receiving the cover-opening confirmation signal, stop broadcasting the cover-opening request signal; wherein the cover-opening confirmation signal is generated when it is determined that the license plate information in the cover-opening request signal is consistent with the license plate information associated with the vehicle.

[0076] After receiving the cover opening request information broadcast by the charging pile in the set frequency band, the vehicle or the control terminal bound to the vehicle obtains the license plate information in the cover opening request information, and compares the license plate information extracted from the local database or cloud server with the license plate information associated with the vehicle. If the extracted license plate information is consistent with the license plate information associated with the vehicle, an opening signal is generated and sent to control the opening of the charging port cover of the vehicle. After confirming that the charging port cover is open, a confirmation opening signal is generated and sent to the charging pile.

[0077] After receiving the cover-opening confirmation signal sent by the vehicle or the control terminal bound to the vehicle, the charging pile stops broadcasting the cover-opening request to charge the vehicle.

[0078] Therefore, the present disclosure adds recognition of vehicle license plates to identify the target vehicle that needs to be charged, enters and stores the license plate information, and when the user removes the charging gun, the radio frequency or Bluetooth broadcast of the charging pile is triggered, and the broadcast content includes the recognized license plate information. When the vehicle receives the broadcast of the corresponding frequency band, the license plate information will be authenticated. If and only if the license plate information is consistent with the license plate information of the vehicle, the charging port cover will be automatically opened; otherwise, there will be no response. The present disclosure can ensure that only the target vehicle automatically opens the charging port cover to prevent other vehicles from accidentally triggering the cover to open.

[0079] For the above step S3, the following is combined with Figure 2 Describe, such as Figure 2 As shown, the above step S3 may include:

[0080] S21, in response to receiving a cover opening confirmation signal, detecting a connection status between a charging gun on a charging pile at a charging parking space and a charging port of the vehicle.

[0081] After receiving the confirmation signal of opening the cover, the charging pile immediately starts the detection mechanism of the charging connection status. For example, through the built-in sensor or communication interface of the charging pile, it monitors in real time whether the charging gun has been successfully inserted into the charging port of the vehicle and confirms whether the connection is stable.

[0082] S22, in response to the connection state being connected, stop broadcasting the cover opening request signal.

[0083] When the detection result shows that the charging gun is connected to the vehicle charging port and the connection is in good condition, the charging pile will automatically stop broadcasting the cover opening request signal. Then, the charging process is started and the vehicle is charged according to the preset charging parameters to ensure the charging process is safe and efficient. During the charging process, the charging pile will continue to monitor the charging status so that any abnormal situation can be discovered and handled in time.

[0084] S23, in response to the connection status being poorly connected or disconnected, generating and sending an alarm signal.

[0085] If the detection results show that the charging gun is poorly connected to the vehicle charging port or has been disconnected, the charging pile will immediately generate and send an alarm signal. The alarm signal can be sent in a variety of ways, such as sending SMS, email or APP push notifications to managers so that they can take prompt action. At the same time, the charging pile may try to resend the cover opening request signal, or instruct managers to go to the site to check and solve the problem to ensure that the charging process can proceed smoothly.

[0086] Therefore, when the present invention detects that the charging gun is connected to the vehicle charging port and is in good condition, it immediately stops broadcasting the cover opening request signal, thereby avoiding unnecessary signal interference and waste of resources; when it detects that the charging gun is poorly connected or disconnected from the vehicle charging port, it sends out an alarm signal, thereby avoiding charging interruptions or safety hazards caused by connection problems, thereby significantly improving charging efficiency and safety.

[0087] In order to more effectively manage the use of charging parking spaces and avoid waste of resources or potential safety hazards caused by vehicle non-response or communication failure, the charging pile of the present invention starts a timer for a set period of time after broadcasting the cover opening request signal to monitor whether a confirmation cover opening signal is received. If the confirmation cover opening signal is not received within the set period of time, the cover opening request signal is stopped from being broadcast. After stopping the broadcast, the charging pile may record an unsuccessful connection attempt and may take further action according to a preset strategy, such as trying to resend the cover opening request signal, sending a notification to the management staff for manual intervention, or entering a waiting state until the next time a vehicle enters the charging area to try to connect again.

[0088] Figure 3 is a schematic diagram of a charging system according to a specific example of the present disclosure.

[0089] like Figure 3 As shown, the charging steps of the charging system of the present disclosure include:

[0090] Vehicle identification and license plate number extraction: When a vehicle, such as an electric vehicle, parks in a charging space, the camera installed on the charging pile automatically takes a photo of the vehicle's license plate number, and the camera transmits the captured license plate number photo to the license plate reading module of the charging pile. The license plate reading module uses image processing technology to analyze the photo, extract the vehicle's license plate number, and transmit the extracted vehicle license plate number to the wireless broadcast module.

[0091] User intention recognition and broadcast start: When the user removes the charging gun with the intention of charging, the gun movement monitoring module on the charging pile will immediately recognize the user's gun-pulling action. In response to the gun-pulling action, the wireless broadcast module starts broadcasting a cover-opening request signal of a set frequency band. The cover-opening request signal can use wireless communication technologies such as Bluetooth broadcasting or radio frequency broadcasting. The broadcast content includes the license plate number of the extracted vehicle to ensure the pertinence and accuracy of the signal. The broadcast range is set to an appropriate distance according to actual needs to avoid signal interference while ensuring reliability.

[0092] Vehicle response and charging port cover opening: When the vehicle or the control terminal bound to the vehicle receives the cover opening signal in the above-mentioned set frequency band, it will first identify the license plate number in the cover opening signal, and compare the identified license plate number with the license plate number stored in itself. If the two are consistent, the vehicle or the mobile terminal bound to the vehicle will control the charging port cover actuator to open the charging port cover to allow the charging gun to be inserted. This mechanism ensures that only the target vehicle can respond to the cover opening request.

[0093] Charging gun insertion and broadcast stop: Before the charging gun is inserted into the charging port, the wireless broadcast module continues to broadcast the cover opening request signal to ensure that the vehicle or control terminal can receive and respond. The charging gun monitoring module on the charging pile monitors the status of the charging gun in real time. Once it is detected that the charging gun has been successfully inserted into the charging port, the wireless broadcast module immediately stops broadcasting the cover opening request signal to avoid unnecessary signal interference and energy consumption.

[0094] In summary, when a vehicle is parked in a charging parking space, the charging pile of the present disclosure performs license plate recognition on the vehicle to obtain the vehicle's license plate information, and when a charging intention is detected at the charging parking space, broadcasts a cover opening request signal containing the license plate information, and when a confirmation cover opening signal is received, stops broadcasting the cover opening request signal; wherein, the confirmation cover opening signal is generated when it is determined that the license plate information in the cover opening request signal is consistent with the license plate information associated with the vehicle. Therefore, the present disclosure increases the recognition of the vehicle license plate to identify the target vehicle that needs to be charged, ensuring that only the target vehicle automatically opens the charging port cover, and avoiding other vehicles from triggering the cover opening by mistake.
