Description

[0001] This application claims priority to Chinese Patent Application No. 202310376120.0, filed on April 10, 2023, with the State Intellectual Property Office of China, entitled “A Charging Control Method, Control Device and Control Equipment”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of charging technology, and in particular to a charging control method, control device and control equipment. Background Technology

[0003] In order to conserve energy and protect the environment, electric vehicles powered by electricity have been vigorously promoted and have gradually gained popularity among consumers. Correspondingly, electric vehicle charging stations set up in public places have also emerged.

[0004] Charging stations typically require users to manually swipe cards or use mobile apps to authorize charging before charging electric vehicles. To simplify the charging process, existing technology offers a plug-and-charge method. After an electric vehicle arrives at a parking space, the charging device there acquires the vehicle's identity information and sends it to a server. The server verifies the vehicle's charging permissions and then releases those permissions, initiating charging. In this process, the server can only determine the corresponding charging device after the charging device sends the vehicle's identity information. In other words, the server cannot determine the appropriate charging device before the vehicle enters the parking space; it can only release charging permissions after the vehicle has entered, impacting charging efficiency.

[0038] The technical solutions of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

[0039] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application.

[0041] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone.

In the description of this application, "at least one" means one or more, and "more" means two or more, unless otherwise explicitly specified.

[0043] To simplify the electric vehicle charging process and improve the user experience, a plug-and-charge method exists. Specifically, after a user parks their electric vehicle in a parking space equipped with charging facilities (such as charging stations), the charging device obtains the electric vehicle's identity information and sends this information, along with the charging station's identity information, to a server. The server verifies the electric vehicle's charging permissions based on its identity information. If the vehicle has charging permissions, the server controls the corresponding charging station to release those permissions based on its identity information. During this process, the user simply plugs the charging gun from the charging device into the electric vehicle's charging port to begin charging.

[0044] During the charging process described above, the server determines the charging station corresponding to the electric vehicle from multiple charging stations based on the identity information sent by the charging station. This means that the server cannot determine the corresponding charging station before the electric vehicle enters the parking space. Therefore, the server can only control the corresponding charging equipment to release charging permissions and allow the electric vehicle to begin charging after it has entered the parking space, thus affecting charging efficiency.

[0045] In view of this, the present application provides a charging control method that determines the target parking space for the first electric vehicle based on a first image, enabling the control device to determine the target parking space before the first electric vehicle enters the parking space, thereby enabling the control device to determine and control the corresponding charging equipment to open the charging permission in advance, thus improving charging efficiency.

[0046] The following combination Figure 1 This application describes a charging control method according to embodiments of the present application. For example... Figure 1 As shown, the charging control method provided in this application embodiment may include steps 110 to 130.

[0047] Step 110: The camera sends a first image of the lane area located at the charging station to the control device.

[0048] The first image is an image that includes the first electric vehicle.

[0049] For example, when the speed of the first electric vehicle is less than a preset threshold, the control device can acquire a first image including the first electric vehicle from the camera at the charging station. For example, the control device can be a server, computer, or other similar device. For example, the preset threshold can be set by staff, configured by the control device based on historical data, or set in other ways. For example, the preset threshold can be set to 0.5 m / s, 0.8 m / s, etc.

[0050] Optionally, the speed of the first electric vehicle in the lane area of ​​the charging station can be determined by a speed sensor.

[0051] Step 120: The control device determines the target parking space for the first electric vehicle based on the first image.

[0052] The target parking space can be the parking space where the first electric vehicle in the charging station is expected to enter.

[0053] Optionally, one implementation of step 120 can be: determining the target parking space for the first electric vehicle based on the minimum distance or angle between the first electric vehicle and the edge line of the parking space in the first image.

[0054] For example, the first image is processed to obtain the minimum distance between the first electric vehicle and the boundary of the parking space. If the minimum distance is less than or equal to a first threshold, then the parking space is the target parking space for the first electric vehicle. The first threshold can be a pre-configured fixed value. The first threshold can be set by staff based on experience; for example, it could be 0.5m, 0.4m, etc.

[0055] Optionally, another implementation of step 120 can be: determining N indicator areas corresponding to the lane area of ​​the first image, and determining the parking space corresponding to the first indicator area where the preset area of ​​the first electric vehicle is located in the N indicator areas as the target parking space.

[0056] The charging station's lane area is divided into M directional zones, each corresponding to one of multiple parking spaces. The M directional zones and parking spaces may not be in a one-to-one correspondence; multiple directional zones may correspond to a single parking space. The N directional zones are N of the M directional zones. M and N are both integers greater than 1, and N ≤ M.

[0057] For example, such as Figure 2 As shown, a panoramic image containing all lane areas of the charging station can be obtained by combining images captured by multiple cameras. Then, the lane areas 240 in the panoramic image are divided into M indicator areas 220 according to preset rules. The M indicator areas 220 can form a matrix, covering the lane areas 240 of the charging station. This application does not limit the size or shape of the M indicator areas 220. For example, the indicator areas 220 can be rectangular blocks, square blocks, etc. The size of the blocks can be smaller than the size of the first electric vehicle in the image, or the length and width of the blocks can be smaller than the width of the parking space, etc. For example, the size of the blocks can be set according to the resolution of the cameras.

[0058] For example, the preset area of ​​the first electric vehicle can be the rear area, the front area, or other areas of the first electric vehicle. For example, such as Figure 2 As shown, the parking space corresponding to the first instruction area 221 where the preset area 211 of the first electric vehicle 210 is located is parking space 5, that is, parking space 5 is the target parking space of the first electric vehicle 210.

[0059] Optionally, one way to determine the N indicator areas corresponding to the lane area of ​​the first image is to determine the N indicator areas corresponding to the camera that captured the first image based on the correspondence between the multiple cameras of the charging station and the M indicator areas. For example, after dividing the lane area of ​​the charging station into M indicator areas, a correspondence between the M indicator areas and the multiple cameras can be established, and this correspondence can be stored in the control device.

[0060] For example, the correspondence between multiple cameras and M indicator areas can be shown in Table 1.

[0061] Table 1

[0062]

[0063]

[0064] For example, if the camera that captures the first image is camera 1, then according to Table 1, the N indicator areas corresponding to the lane area in the first image can be determined as the six indicator areas from indicator area 1 to indicator area 6. If the camera that captures the first image is camera 3, then according to Table 1, the N indicator areas can be determined as the six indicator areas from indicator area 13 to indicator area 18.

[0065] Optionally, another way to determine the N indicator areas corresponding to the lane area of ​​the first image can be: determine the position of the lane area of ​​the first image in the lane area of ​​the charging station based on the second image, and determine the N indicator areas corresponding to the lane area of ​​the first image based on the position.

[0066] The second image includes the boundary of the lane area in the first image, and the second image and the first image were captured at the same time.

[0067] Specifically, by combining the first and second images, the exact location of the charging station's lane area captured in the first image can be determined. Based on this location and the correspondence between the location and the M indicator areas, N indicator areas can be determined. For example, ... Figure 3 As shown, position 1 in the lane area of ​​the charging station corresponds to indicator areas 1 to 4, position 2 corresponds to indicator areas 5 to 8, and position 3 corresponds to indicator areas 9 to 12. If the lane area of ​​the first image is position 2 in the lane area of ​​the charging station, then N indicator areas can be determined as the four indicator areas from indicator areas 5 to indicator areas 8.

[0068] For example, in determining the target parking space for a first electric vehicle based on N indicator areas, there may be a situation where multiple indicator areas among the M indicator areas correspond to the parking space corresponding to the first indicator area. In this case, determining the parking space corresponding to the first indicator area where the preset area of ​​the first electric vehicle is located among the N indicator areas as the target parking space may include: determining whether a first dwell time is greater than a second dwell time; if the first dwell time is greater than the second dwell time, then the parking space corresponding to the first indicator area is determined to be the target parking space for the first electric vehicle. Here, the first dwell time is the dwell time of the first electric vehicle in the first indicator area, and the second dwell time is the dwell time of other electric vehicles in other indicator areas corresponding to the multiple indicator areas.

[0069] For example, such as Figure 2 As shown, the parking space corresponding to the first instruction area 221 where the preset area 211 of the first electric vehicle 210 is located is parking space 5, and the parking space corresponding to the second instruction area 222 where the preset area 231 of the second electric vehicle 230 is located is also parking space 5. At this time, if the dwell time of the first electric vehicle 210 in the first instruction area 221 (i.e., the first dwell time, for example, the first dwell time is 3 minutes) is greater than the dwell time of the second electric vehicle 230 in the second instruction area 222 (i.e., the second dwell time, for example, the second dwell time is 1 minute), then parking space 5 is the target parking space for the first electric vehicle 210.

[0070] Step 130: The control device sends a start charging command to the charging equipment in the target parking space.

[0071] The "Start Charging" command is used to instruct the charging device to release charging permissions.

[0072] Specifically, after receiving the charging start command, the charging device at the target parking space releases its charging permission. At this point, after the user parks, they can insert the charging gun of the charging device into the charging port of the first electric vehicle, allowing the charging device to charge the first electric vehicle.

[0073] According to the charging control method provided in this application, the control device first acquires a first image of the lane area of ​​the charging station, including the first electric vehicle, from a camera, and then determines the target parking space for the first electric vehicle based on the first image. After determining the target parking space, the control device can send a start charging command to the charging equipment at the target parking space, controlling the charging equipment at the target parking space to release its charging permission, so that the charging equipment can start charging the first electric vehicle. The charging control method provided in this application, by determining the target parking space for the first electric vehicle based on the first image, enables the control device to determine the charging equipment corresponding to the first electric vehicle before the first electric vehicle enters the parking space, thereby enabling the control device to control the charging equipment to open its charging permission to charge the first electric vehicle in advance, thus improving charging efficiency and enhancing the user's charging experience.

[0074] Furthermore, in some embodiments, the charging control method may also include sending an unlocking command to the parking lock of the target parking space. The unlocking command instructs the parking lock to unlock. After determining the target parking space for the first electric vehicle, sending the unlocking command to the parking lock enables the control device to unlock the parking lock before the first electric vehicle enters the target parking space (e.g., to place the parking lock in a horizontal position), eliminating the need for additional user operations (e.g., scanning a code for registration), thereby simplifying the charging process, improving parking convenience, and enhancing the user's charging experience.

[0075] In some embodiments, to facilitate subsequent billing operations and improve the user's charging experience, the charging control method may further include obtaining the identity information of a first electric vehicle before sending a start charging command to the charging equipment in the target parking space; determining whether the first electric vehicle has charging permissions based on the identity information; and, if the first electric vehicle has charging permissions, sending a start charging command to the charging equipment in the target parking space. For example, the identity information may be license plate information, a vehicle identification number (VIN), or other information that can represent the first electric vehicle.

[0076] For example, the identity information can be used to label the driver's identity or account information. The control device can pre-store the binding relationship between the electric vehicle's identity information and the driver's charging account. After the control device obtains the first electric vehicle's identity information, if the binding relationship includes the first electric vehicle's identity information, then the first electric vehicle has charging permission; if the binding relationship does not include the first electric vehicle's identity information, then the first electric vehicle does not have charging permission.

[0077] In some embodiments, to improve charging safety, such as Figure 4 As shown, the charging control method may further include steps 410 to 450.

[0078] Step 410: The camera sends the model information of the first electric vehicle to the control device.

[0079] For example, vehicle type information can be any of the following: pure electric vehicles (BEV), extended range electric vehicles (EREV), plug-in hybrid electric vehicles (PHEV).

[0080] Step 420: The first electric vehicle sends its battery information and required charging power to the control device.

[0081] For example, the battery management system (BMS) in the first electric vehicle can monitor the battery status (such as temperature, charging current, charging voltage, etc.) and calculate the required charging power of the battery based on the battery status.

[0082] Step 430: The charging equipment in the target parking space sends its maximum charging power to the control device.

[0083] The maximum charging power of the charging device is the rated charging power of the charging device.

[0084] Step 440: The control device determines the target charging power.

[0085] The target charging power is the minimum value among the maximum charging power, the required charging power, and the maximum safe charging power. The maximum safe charging power is the maximum actual charging power determined based on the vehicle model information and battery information of the first electric vehicle. For example, the actual charging power of multiple electric vehicles with the same model and battery information as the first electric vehicle is obtained, and the average of the actual charging power of these multiple electric vehicles is taken as the maximum actual charging power of the first electric vehicle. For instance, if the actual charging power of electric vehicle 1 is 3kW, the actual charging power of electric vehicle 2 is 3.6kW, and the actual charging power of electric vehicle 3 is 4.5kW, then the maximum actual charging power of the first electric vehicle is 3.7kW.

[0086] Step 450: The control device sends a target charging command to the charging equipment in the target parking space.

[0087] The target charging instruction is used to instruct the charging equipment to charge the first electric vehicle at a target charging power.

[0088] According to the charging control method provided in this application, before charging an electric vehicle, a target charging power for the first electric vehicle can be determined based on the maximum charging power of the charging equipment, the vehicle model information, the battery information, and the required charging power of the first electric vehicle. Then, the charging equipment is controlled to charge the first electric vehicle at the target charging power. By determining the target charging power, the control device can control the charging equipment to charge the first electric vehicle at the target charging power, thereby improving charging safety.

[0089] Furthermore, in some embodiments, to ensure charging safety, the charging control method may further include controlling the fire protection system to execute fire safety measures upon receiving a charging anomaly message from the charging equipment of the first electric vehicle or the target parking space. For example, the charging anomaly message may be that the charging current or charging voltage exceeds a first threshold, or that the battery temperature or charging gun temperature exceeds a second threshold, or other charging anomalies. The first and second thresholds can be preset values, which can be set by personnel based on experience. For example, the first threshold may be 20A, and the second threshold may be 45°C. For example, fire safety measures may include turning on the sprinkler system, turning on the ventilation system, turning on the alarm device, or other safety measures.

[0090] To better understand the charging control method provided in the embodiments of this application, the following is combined with... Figure 5 and Figure 6The charging process of the first electric vehicle at the charging station is described in detail.

[0091] For example, when a first electric vehicle enters the charging station, the camera in the barrier gate system acquires the vehicle's model and identity information and sends this information to the control device (e.g., a server). This is step 502. After passing through the barrier gate system, the first electric vehicle travels along the lane area of ​​the charging station. When the vehicle's speed is determined to be less than a preset threshold, the camera in the security system captures an image and sends it to the control device. This is step 504, which is the same as step 110. After acquiring the first image, the control device determines the target parking space for the first electric vehicle based on the image. This is step 506, which is the same as step 120. The control device can then unlock the parking lock at the target parking space and determine whether the first electric vehicle has charging permission based on the identity information. This is steps 508 and 510. If the first electric vehicle has charging permission, the control device sends a start charging command to the charging equipment at the target parking space. Upon receiving the command, the charging equipment releases the charging permission, allowing the first electric vehicle to begin charging. This is steps 512 and 514. If the first electric vehicle does not have charging permission, the user manually registers a charging account and binds the charging account to the first electric vehicle's identity information, thus granting the first electric vehicle charging permission and enabling the charging equipment to charge it. During this process, the control device can also turn on the vehicle indicator light of the target parking space to assist the first electric vehicle in driving into the target parking space.

[0092] After the first electric vehicle enters the target parking space and begins charging, the control device can obtain the charging status information (such as charging current and charging voltage) of the first electric vehicle, monitor its charging status in real time, and promptly control the fire protection system to take fire-fighting measures upon receiving abnormal messages from the first electric vehicle or the charging equipment. After the first electric vehicle stops charging, the control device determines the charging fee and parking fee. Then, the control device can send a charging completion message, charging fee, and parking fee to the terminal of the user of the first electric vehicle. This is step 516. Next, the control device determines whether the user of the first electric vehicle has consumed any third-party services (such as catering, car wash, leisure and entertainment). If third-party services are consumed, the third-party service fee is determined based on the identification code corresponding to the first electric vehicle's identity information. This is steps 518 and 520. If no third-party services are consumed, step 522 is executed. Then, the control device determines the total cost of the first electric vehicle and controls the gate system to display the cost and payment code when the first electric vehicle leaves the charging station. This is step 522.

[0093] This system includes communication connections between the barrier gate system, security system, third-party service system, fire protection system, and control devices. For example, communication connections can be achieved via Ethernet, Wireless Fidelity (WiFi), or 4G / 5G, enabling data sharing among them.
