[0001] The present invention relates to the technical field of electric vehicle charging infrastructure, and in particular to a charging management method, device and system for a charging vehicle. Background Art

[0002] With the increasing popularity of electric vehicles, the user population of new energy vehicles has further expanded, and the corresponding charging infrastructure is being built. In terms of charging services, various units such as operating companies, equipment manufacturers and individual merchants can carry out charging service businesses. In the current actual operation process, there are the following problems: vehicles occupy charging parking spaces, resulting in low efficiency of charging pile charging services; vehicles enter the garage due to abnormal operation or insufficient guidance, resulting in pile collision accidents; charging stations are not smart enough and cannot provide timely and effective answers, resulting in problems such as failure to charge. The above defects seriously affect consumers' experience of the charging process, hinder consumers' enthusiasm for the use of electric vehicles, and become a major factor that makes it difficult for various operating entities to quickly realize benefits, and have become a problem that needs to be solved urgently.

[0003] The existing technologies mostly use different modules to arrange multiple vehicles in parking spaces for detection and management, which is mainly used to distinguish fuel vehicles from electric vehicles. The practical application is not strong and cannot effectively solve the above-mentioned problems. To this end, the present invention proposes a vehicle charging management method to meet various needs such as vehicle identification, charging management, vehicle guidance and service response during operation. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a charging management method, device and system for charging vehicles to solve the problems in the prior art mentioned above, such as low charging service efficiency, easy collision with charging piles without position guidance, and unintelligent charging piles.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A charging management method for a charging vehicle, the method comprising:

[0007] S1. Vehicle identification step. Use the vehicle identification unit on the charging pile to capture the license plate information of the vehicle entering the charging service area, upload the information to the EVM charging management device, and the EVM charging management device determines whether it is a serviceable vehicle. If it is a serviceable vehicle, go to step S2. If it is not a serviceable vehicle, the EVM charging management device reminds through the sound and light responder of the charging pile and ends the service. If an abnormality occurs in the step, go to step S5;

[0008] S2. Vehicle positioning step. The EVM charging management device controls the intelligent ground lock to hide in the ground, starts the pile-mounted radar to monitor the distance between the vehicle and the charging pile when the vehicle moves into the parking space, and when the distance is less than the set threshold, the charging pile's sound and light responder is used to give a sound and light prompt and the pile-mounted radar uploads the data to the EVM charging management device. After the vehicle stops for a certain period of time, the intelligent ground lock is controlled to extend out of the ground and its state and the distance sensor thereon are used to detect whether the vehicle is parked in a standardized manner, and the sound and light responder is controlled to remind the driver until the vehicle is parked in a standardized manner, and then the process goes to step S3. If the vehicle cannot be parked in a standardized manner, the sound and light responder is used to prompt that the charging service will not be provided and the service platform is reported for management. If an abnormality occurs in the step, the process goes to step S5;

[0009] S3. Vehicle charging step. After the EVM charging management device confirms the charging connection, it controls the EVC charging unit of the charging pile to provide charging services for the vehicle, and reports the data generated during charging to the service platform for management. After the vehicle is charged, it controls the EVC charging unit to end charging and proceeds to step S4. If an abnormality occurs in the step, proceed to step S5;

[0010] S4. End charging step. The EVC charging unit notifies the EVM charging management device that the vehicle has completed charging. The EVM charging management device uses the interactive unit to remind the driver to leave the charging parking space in time. After the vehicle leaves, when the vehicle identification unit no longer finds the vehicle in the parking space, it notifies the EVM charging management device to extend the smart ground lock to wait for the next charging service. If the vehicle does not leave beyond the specified time, the EVM charging management device extends the smart ground lock for temporary control. If an abnormality occurs in the step, go to step S5;

[0011] S5. Service response step. The operator uses the call button of the interactive unit to notify the customer service unit of the EVM charging management device to access the service platform, and then interacts with the customer service unit through the voice module of the interactive unit to obtain instant answers and guidance from the sound and light responder.

[0012] Preferably, the data generated during charging in step S3 includes battery status, charging parameters and device status.

[0013] Preferably, the step of the EVM charging management device detecting whether the vehicle is parked properly in step S2 includes: if the EVM charging management device detects that any one of the smart ground locks cannot extend out of the ground, it is determined that the vehicle is parked improperly; when all the smart ground locks can extend out of the ground, the nominal threshold of the distance between the vehicle wheels and the smart ground lock is set to S, and the EVM charging management device detects through the distance sensor of the smart ground lock that the distance between the vehicle wheels and the smart ground lock is greater than S, then it is determined that the vehicle is parked improperly; the distance difference between the same group of wheels of the vehicle and the smart ground lock is set to ΔS, and when the ΔS exceeds a certain threshold, it is determined that the vehicle is parked improperly.

[0014] Preferably, the step of controlling the sound and light responder in step S2 to remind the driver until the vehicle is parked in accordance with the specification includes: if any of the smart ground locks cannot extend out of the ground or the distance between the vehicle wheels and the smart ground locks is greater than S, the EVM charging management device controls the sound and light responder to prompt that the vehicle position is inappropriate and reminds the driver to adjust the front and rear position of the vehicle in the parking space; if ΔS exceeds a certain threshold, the EVM charging management device controls the sound and light responder to prompt that the vehicle is tilted and reminds the driver to adjust the direction of the vehicle.

[0015] Preferably, step S5 may also include the following steps: the customer service unit of the service platform controls the camera in the vehicle identification unit to remotely view the site for guidance, answers and troubleshooting.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] This embodiment provides a technical solution: a charging management method for a charging vehicle, the method comprising:

[0036] S1 vehicle identification step. Use the vehicle identification unit 22 on the charging pile 26 to capture the license plate information of the vehicle 4 entering the charging service area, upload the information to the EVM charging management device 21, and the EVM charging management device 21 determines whether it is a serviceable vehicle. If it is a serviceable vehicle, go to step S2. If it is not a serviceable vehicle, such as a fuel vehicle, a special vehicle, etc., the EVM charging management device 21 reminds and ends the service through the sound and light responder 251 of the charging pile 26. If an abnormality occurs in the step, go to step S5; in this step, the license plate recognition can be performed by using the license plate color, or after the license plate number is recognized, it can be compared with the database;

[0037] S2 Vehicle positioning step. The EVM charging management device 21 controls the intelligent ground lock 241 to hide in the ground, and starts the pile-borne radar 242 to monitor the distance between the vehicle 4 and the charging pile 26 when the vehicle 4 moves into the parking space 5. When the distance is less than the set threshold, the sound and light responder 251 of the charging pile 26 is used to give a sound and light prompt, and the pile-borne radar 242 uploads the data to the EVM charging management device 21. After the vehicle 4 stops for a certain period of time, the intelligent ground lock 241 is controlled to extend out of the ground and detect whether the vehicle 4 is parked in accordance with the regulations through its state and the distance sensor thereon. The sound and light responder 251 is controlled to remind the driver until the vehicle 4 stops in accordance with the regulations, and then the process goes to step S3. If the vehicle 4 stops, If the vehicle cannot be parked in a standardized manner, an acoustic and optical responder 251 is used to prompt that the charging service will not be provided and the service platform 1 is reported for management. If an abnormality occurs in the step, go to step S5. In this step, a variety of solutions can be used to determine whether the parking is standardized, such as setting a camera at the bottom or top of the parking space for video recognition analysis or other methods. A method provided by us will be described in detail later as an embodiment: that is, using an intelligent ground lock 241 with a distance sensor to control whether the parking is standardized. The specific steps are as follows: the EVM charging management device 21 detects that any of the intelligent ground locks 241 cannot extend out of the ground, then it is determined that the vehicle 4 is not parked in a standardized manner. At this time, The EVM charging management device 21 controls the sound and light responder 251 to prompt that the position of the vehicle 4 is not suitable and reminds the driver to adjust the front and rear position of the vehicle 4 in the parking space 5; when the smart ground locks 241 can all be extended out of the ground, the nominal threshold value of the distance between the wheels of the vehicle 4 and the smart ground lock 241 is set to S, and the EVM charging management device 21 detects through the distance sensor of the smart ground lock 241 that the distance between the wheels of the vehicle 4 and the smart ground lock 241 is greater than S. In the attached figure, in this state, the distance between the left wheel and the smart ground lock 241 is S21, and the distance between the right wheel and the smart ground lock 241 is S22. Both S21 and S22 are greater than the threshold S. At this time, it is also determined that the parking of the vehicle 4 is not standardized. At this time, the EVM charging management device 21 controls the sound and light responder 251 to still prompt that the position of the vehicle 4 is not suitable and reminds the driver to adjust the front and rear position of the vehicle 4 in the parking space 5; the distance difference between the same group of wheels of the vehicle 4 and the smart ground lock 241 is set to ΔS. In the accompanying drawing, in this state, the distance between the left wheel and the smart ground lock 241 is S31, and the distance between the right wheel and the smart ground lock 241 is S32. The difference between S31 and S32 is ΔS. When ΔS exceeds a certain threshold, it is determined that the vehicle 4 is parked improperly. At this time, the EVM charging management device 21 controls the sound and light responder 251 to prompt the vehicle 4 to tilt and remind the driver to adjust the direction of the vehicle 4.

[0038] S3 vehicle charging step. After the EVM charging management device 21 confirms the charging connection, it controls the EVC charging unit 23 of the charging pile 26 to provide charging services for the vehicle 4, and at the same time reports the data generated during charging to the service platform 1 for management. After the charging of the vehicle 4 is completed, the EVC charging unit 23 is controlled to end the charging and proceed to step S4. If an abnormality occurs in the step, proceed to step S5. The data generated during charging in this step includes battery status, charging parameters and device status, so that the service platform 1 can perform big data evaluation and analysis on the service status of the charging pile 21.

[0039] S4 ends the charging step. The EVC charging unit 23 notifies the EVM charging management device 21 that the vehicle 4 has completed charging. The EVM charging management device 21 uses the interactive unit 25 to remind the driver to leave the charging parking space 5 in time. After the vehicle 4 leaves, when the vehicle identification unit 22 no longer finds the vehicle 4 in the parking space 5, it notifies the EVM charging management device 21 to extend the smart ground lock 241 to wait for the next charging service. If the vehicle 4 does not leave after exceeding the specified time, the EVM charging management device 21 extends the smart ground lock 241 for temporary control. If an abnormality occurs in the step, go to step S5; the temporary control can adopt punitive billing or continuous voice alarm and other measures.

[0040] S5 Service response step. The operator uses the call button 252 of the interactive unit 25 to notify the EVM charging management device 21 to access the customer service unit of the service platform 1, and then interacts with the customer service unit through the voice module of the interactive unit 25, and obtains instant answers and guidance from the sound and light responder 251. Furthermore, the customer service unit of the service platform 1 can also control the camera 221 in the vehicle identification unit 22 to remotely view the site for guidance, answers and troubleshooting, giving users a better service experience.

[0041] Based on the same inventive concept, the present application also provides an embodiment of a charging vehicle charging management device, including an EVM charging management device 21, a vehicle identification unit 22, an EVC charging unit 23, a garage management unit 24, and an interactive unit 25. The EVC charging unit 23 is connected to the EVM charging management device 21 via CAN, and the vehicle identification function unit 22, the garage management function unit 24 and the interactive unit 25 are connected to the EVM charging management device 21 via Ethernet. The vehicle identification unit 22 includes a camera 221, and the camera 221 is used to capture images of the vehicle 4. The EVM charging management device 21 is used to identify whether the vehicle 4 is charged or not, control the garage management unit 24 to manage the vehicle in place, control the EVC charging unit 23 to charge the vehicle 4, and receive, process and send data from other units. The EVC charging unit 23 is used to perform charging and billing of the vehicle 4. The EVC charging unit 23 at least includes a TCU billing communication unit, an ECU charging controller, a power module, and a charging gun of the charging pile, and is the main part for charging.

[0042] The garage management unit 24 includes an intelligent ground lock 241 installed on the ground parking space 5 of the charging garage in a left-right alignment and a pile-borne radar 242 installed at the front end of the charging pile 26 facing the position where the vehicle 4 is placed. The intelligent ground lock 241 is connected perpendicular to the direction of travel of the vehicle 4 and its position corresponds to the position of the wheel of the vehicle 4. The intelligent ground lock 241 maintains a safe distance from the charging pile 26 and is equipped with a distance sensor facing the wheel direction. The intelligent ground lock 241 extends or hides in the ground to detect and control the position of the vehicle 4. The pile-borne radar 242 is used for anti-collision detection of the vehicle 4. When the distance between the vehicle and the charging pile 26 is less than a certain value, the sound and light responder is used to send a sound and light signal in time to remind the driver to control the vehicle in time to prevent the vehicle from colliding with the charging pile, and upload the distance data to the EVM charging management device 21. A collision sensor can also be set in the charging pile 26. If a collision accident occurs, the camera 221 can record the collision video and push it to the service platform 1 in time, saving the accident evidence while reminding the maintenance personnel to check the charging pile 26 in time and pursue the responsibility and claim. In order to better detect and identify the parking position of the vehicle 4 in the parking space 5, the smart ground locks 241 installed on the ground parking space 5 of the charging garage in a left-right alignment can be two pairs of front and rear vehicle locks, and the position of the vehicle 4 is identified and judged using a similar method to the front speed.

[0043] The interaction unit 25 at least includes a call button 252 and a voice module, which are placed at the front end of the charging pile 26 in this embodiment. When the operator encounters a problem, he can access the customer service unit of the remote service platform 1 through the call button 252. The remote customer service unit can also use the camera 221 of the vehicle identification unit 22 for operation guidance. In this scenario, the camera 221 is configured as a rotatable camera, so that the camera 221 can better observe the operator and other environments in front of the charging pile 26, and solve the charging problem through remote guidance. At this time, the camera 221 has the functions of license plate acquisition and video interaction. Compared with the independent configuration camera, the device structure is simplified and the cost is saved. The charging pile 26 is configured with a screen, which is used for the operator to operate the functions of the charging pile and interact with the video of the customer service unit of the remote service platform 1. The operator can reflect the problem more intuitively and communicate more efficiently. The screen is a display device that displays information to the user, and is not limited to a specified form, for example, a CRT cathode ray tube or an LCD liquid crystal display type, nor is it limited to whether it has a touch screen for interaction. The sound and light responder 261 has the function of playing sound and flashing reminders, and is used for reminding the whole process of the charging management method for the charging vehicle.

[0044] Based on the same inventive concept, the present solution also provides a charging management system for charging vehicles, including a remote service platform 1 and the local charging management device 2 for charging vehicles, wherein the charging management device 2 for charging vehicles is connected to the remote service platform 1 via wireless communication, and the service platform 1 is used to receive information sent by the charging management device 2 for charging vehicles and manage the charging management device 2 for charging vehicles, and the remote service platform 1 includes a customer service unit, which is used to manually interact with local operators. In this embodiment, the wireless communication uses a cellular wireless network 32, and a 4G / 5G network with a faster transmission speed is selected. A wired local area network can also be used when the on-site installation conditions are met, and no digital communication method is limited.

[0045] The above is only a preferred specific implementation method of the present scheme, but the protection scope required by the present scheme is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical scheme and inventive concept of the present application within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present application.
