Description

Technical Field

[0001] This application relates to the field of new energy vehicles, and in particular to a vehicle battery swapping method and a vehicle. Background Technology

[0002] Battery swapping is a new energy replenishment method in the new energy vehicle industry, aiming to provide energy to new energy vehicles by quickly replacing battery modules. Compared with traditional charging methods, this mode is more efficient and convenient, helping to solve problems such as slow charging, range anxiety, and battery life management for new energy vehicles.

[0003] In traditional battery swapping, the user typically parks their vehicle in a designated area within the station, and the station then performs the battery swap. During this process, the vehicle's condition must meet the swapping requirements; otherwise, the swap may fail or even lead to a safety accident. However, users may forget or misoperate, causing the vehicle to become unsuitable for battery swapping. Summary of the Invention

[0004] This application provides a vehicle battery swapping method and a vehicle to ensure the safety of the battery swapping process.

[0005] In a first aspect, this application provides a vehicle battery swapping method, applied to the vehicle's on-board terminal, the method comprising:

[0006] Acquire vehicle status data; the vehicle status data includes any one or any combination of the following: steering wheel rotation angle, handbrake status indicator signal, foot brake status indicator signal, gear status indicator signal, door status indicator signal, power supply connection signal of the vehicle power unit, and battery pack health status data.

[0007] When the vehicle status data meets the preset conditions, a battery swapping start command is sent to the battery swapping station that has established a communication connection with the vehicle; the vehicle status data meeting the preset conditions indicates that the vehicle status meets the battery swapping requirements, and the battery swapping start command is used to instruct the battery swapping station to perform the battery swapping operation.

[0008] The vehicle battery swapping method provided in this application first acquires vehicle status data, and when the vehicle status meets preset conditions, sends a battery swapping start command to a battery swapping station with which a communication connection has been established, so that the battery swapping station can perform the battery swapping operation.

[0009] In this way, the vehicle checks its own status data before the battery swap, avoiding the operation if the vehicle status data does not meet the preset conditions, thus ensuring the normal progress of the battery swap and improving the safety of the swap. Users do not need to get out of the vehicle to check; the onboard terminal can achieve fully automated detection, improving the user's battery swap experience.

[0010] In one possible implementation, the preset conditions include any one or any combination of the following:

[0011] The steering wheel rotation angle is within a preset angle range;

[0012] The handbrake status indicator signal indicates that the handbrake is in the released state;

[0013] The foot brake status indicator signal indicates that the foot brake is in the released state;

[0014] The gear position indicator signal indicates that the vehicle is in neutral (N) gear.

[0015] Each of the aforementioned door status indicator signals indicates that the corresponding door is in the closed state;

[0016] The power supply connection signal of the vehicle's power unit indicates that the power supply connection of the vehicle's power unit is disconnected;

[0017] The health status data of the battery pack indicates that the health status of the battery pack meets the usage requirements.

[0018] This implementation provides specific data acquisition devices and preset conditions. These devices can collect vehicle status data and reflect the vehicle status of the electric vehicle. Only when the current vehicle status meets these preset conditions will the on-board terminal issue a battery swap start command, thereby ensuring that the battery swap process can be completed safely.

[0019] In one possible implementation, before sending a battery swapping start command to a battery swapping station with which the vehicle has a communication connection, if the vehicle status data meets preset conditions, the method further includes:

[0020] The vehicle information and battery pack information are sent to the battery swapping station; if the vehicle information and battery pack information are verified, the battery swapping station performs the corresponding battery swapping operation.

[0021] In this implementation, the vehicle terminal sends the electric vehicle's identification information and battery pack information to the battery swapping station in advance so that the station can verify them. Only if the verification is successful will the corresponding battery swapping operation be performed based on the vehicle identification information and battery pack information, thus ensuring the legality of the battery pack and the safety of the battery swapping process.

[0022] In one possible implementation, after sending a battery swapping start command to a battery swapping station with which the vehicle has a communication connection, when the vehicle status data meets preset conditions, the method further includes:

[0023] The system receives and displays payment order information for battery swapping orders sent by the cloud server; the order information is sent from the battery swapping station to the cloud server, and the cloud server generates payment order information based on the order information.

[0024] Receive payment input from the user regarding the payment order information and process the payment for the battery swap order.

[0025] In one possible implementation, after sending a battery swapping start command to a battery swapping station with which the vehicle has a communication connection, when the vehicle status data meets preset conditions, the method further includes:

[0026] If the battery swap is successful and the vehicle is detected to have left the battery swap station, the communication connection with the battery swap station is disconnected.

[0027] In one possible implementation, after sending a battery swapping start command to a battery swapping station with which the vehicle has a communication connection, when the vehicle status data meets preset conditions, the method further includes:

[0028] Get vehicle battery swapping progress;

[0029] Output battery swapping progress information.

[0030] In this implementation, the current battery swapping progress is output to the user in real time during the battery swapping process, so that the user can accurately understand the current progress, allocate their time reasonably, and thus improve the user experience.

[0031] In one possible implementation, the step of sending a battery swapping start command to a battery swapping station with which the vehicle has a communication connection when the vehicle status data meets preset conditions includes:

[0032] If the vehicle status data meets the preset conditions, an inquiry message is output; the inquiry message is used to prompt the user whether to confirm the battery swap.

[0033] In response to the user's confirmation of the query information, the battery swapping start command is sent to the battery swapping station.

[0034] In this implementation, by outputting query information, the battery swapping start command is issued only when the vehicle status meets the preset conditions and the user confirms the start of battery swapping, thus ensuring the controllability of the battery swapping process.

[0035] In one possible implementation, after acquiring the vehicle status data, the method further includes:

[0036] If the vehicle status data does not meet the preset conditions, a vehicle status prompt message is output; the vehicle status prompt message is used to prompt the user to adjust the vehicle status so that the vehicle status data meets the preset conditions.

[0037] Secondly, this application also provides a vehicle, comprising:

[0038] A status acquisition device is used to acquire vehicle status data; the vehicle status data includes any one or any combination of the following: steering wheel rotation angle, handbrake status indicator signal, foot brake status indicator signal, gear status indicator signal, door status indicator signal, power supply connection signal of the vehicle power unit, and battery pack health status data.

[0039] The vehicle-mounted terminal is connected to the status acquisition device and is used to receive the vehicle status data sent by the status acquisition device.

[0040] The vehicle-mounted terminal is also used to establish a communication connection with the battery swapping station, so as to send a battery swapping start command to the battery swapping station when the vehicle status data meets the preset conditions; the vehicle status data meeting the preset conditions indicates that the vehicle status meets the battery swapping requirements, and the battery swapping start command is used to instruct the battery swapping station to perform the battery swapping operation.

[0041] In one possible implementation, the status acquisition device is connected to the vehicle-mounted terminal via the vehicle's own communication bus.

[0042] This implementation method achieves vehicle-wide communication through the electric vehicle's own communication bus, which can reduce communication latency, improve efficiency, and enhance the user experience. Attached Figure Description

[0057] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0058] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0059] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0060] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0061] In the description of the embodiments in this application, 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, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0062] In the description of the embodiments of this application, the term "multiple" refers to two or more (including two), similarly, "multiple sets" refers to two or more (including two sets), and "multiple pieces" refers to two or more (including two pieces).

[0063] The battery swapping model for new energy vehicles is gradually becoming more widespread. In the traditional battery swapping process for new energy vehicles, the vehicle enters the designated battery swapping area of ​​the swapping station, parks in the designated location, and the swapping station finds the battery to be replaced according to the vehicle's battery model, and then performs the battery replacement operation.

[0064] However, the battery is a crucial component of a vehicle, providing voltage to the entire vehicle. Abnormalities during the battery swapping process can lead to serious safety accidents. For example, the vehicle's condition can affect the swapping process. If the vehicle moves during the swapping process before it has come to a complete stop, or if the vehicle's condition does not meet the requirements for battery swapping, not only will the swap fail, but it may also trigger a safety incident.

[0065] Therefore, it is necessary to ensure that the vehicle's condition meets the requirements before starting the battery swap; otherwise, the swap may fail or even cause a safety accident. Users may forget or misoperate, resulting in the vehicle not meeting the swap conditions. Therefore, to solve the above technical problems, the vehicle's condition can be checked before the swap to avoid these situations.

[0066] As a feasible implementation method, this application provides a vehicle battery swapping method applied to a vehicle's on-board terminal. The on-board terminal is a front-end device of the vehicle monitoring and management system, possessing service scheduling functions and data processing capabilities. It can acquire and process data from the entire vehicle and communicate with other devices. Figure 1 This is a flowchart illustrating a first vehicle battery swapping method provided in some embodiments of this application. Figure 1 As shown, the method includes the following steps:

[0067] S101: Obtain vehicle status data.

[0068] As an optional implementation method, vehicle status data can be collected using status acquisition devices installed on the vehicle. The number, type, and installation location of these devices are not limited; they can be selected based on the vehicle status data required.

[0069] As an optional implementation, vehicle status data may include any one or any combination of the following: steering wheel rotation angle, handbrake status indicator signal, foot brake status indicator signal, gear status indicator signal, door status indicator signal, power supply connection signal of the vehicle power unit, and battery pack health status data.

[0070] Based on the vehicle status data mentioned above, corresponding status acquisition devices can be selected. For example, if it is necessary to obtain the steering wheel rotation angle, a steering wheel rotation angle sensor needs to be set up; if it is necessary for the handbrake, foot brake, etc. to be in the released state during battery swapping, as well as if it is necessary for the vehicle to be in neutral (N) gear, all doors to be closed, and the vehicle's internal voltage to be below the voltage threshold, then the corresponding acquisition devices need to be set up.

[0071] As an optional implementation method, the vehicle terminal can be connected to the status acquisition device, and the vehicle terminal can acquire the vehicle status data collected by the status acquisition device, and then analyze and process the vehicle status data.

[0072] S102: Determine whether the vehicle status data meets the preset conditions; if the vehicle status data meets the preset conditions, trigger S103.

[0073] After acquiring the vehicle status data collected by the status acquisition device, it is necessary to determine whether the vehicle status is suitable for battery swapping based on the vehicle status data, that is, to determine whether the vehicle status data meets the preset conditions.

[0074] The vehicle's status is determined based on vehicle status data, which then helps determine if the vehicle is suitable for battery swapping. For example, during battery swapping, it's best to ensure the steering wheel is straight, the handbrake and foot brake are released, all doors are closed, and the vehicle is in neutral (N) to ensure a safe and successful battery swapping process.

[0075] The specific content of the preset conditions is set according to the actual situation. As a feasible implementation method, after obtaining the steering wheel rotation angle, it is necessary to use this data to determine whether the steering wheel has returned to center. At this time, the preset condition can be that the steering wheel rotation angle is within a preset angle range. Alternatively, after obtaining the voltage data inside the vehicle, it can be determined whether the power supply connection of the vehicle's power unit is disconnected, thereby ensuring the safety of battery swapping.

[0076] S103: Send a battery swapping start command to the battery swapping station that has established a communication connection with the vehicle.

[0077] The vehicle has a pre-established communication connection with the battery swapping station; the vehicle can communicate through its own onboard terminal. As a feasible implementation method, when a vehicle enters the station, the battery swapping station can scan the license plate and other vehicle identification information with a camera, then send the vehicle identification information to a cloud server to query the vehicle's factory-installed Bluetooth device address resolution key information, and establish Bluetooth communication with the vehicle through the Bluetooth device within the battery swapping station.

[0078] As an optional embodiment, after establishing communication, the battery swapping station can send the vehicle's arrival signal to the on-board terminal to wake up the on-board software. The on-board software can read the data from the status acquisition device in real time through the CarService on-board service, and can also provide corresponding prompts to the user through the display screen.

[0079] In practical applications, since vehicles and battery swapping stations have established a communication connection, as an optional implementation method, the station can send the battery swapping location to the vehicle terminal so that the user can drive the vehicle to the corresponding location. Furthermore, the vehicle's autonomous driving system can be used to automatically drive the vehicle to the swapping station, further enhancing the battery swapping experience.

[0080] When the vehicle's status meets preset conditions, the on-board terminal sends a battery swapping start command to the battery swapping station, enabling the station to perform the swapping operation. As a feasible implementation, the battery swapping station can be equipped with robotic arms or other execution devices. Upon receiving the start command, the station controls the execution device to locate the target battery and replace the vehicle's original battery with it. At this time, the on-board terminal can display that the vehicle is in battery swapping mode, preventing accidental user operation from affecting the swapping process.

[0081] The vehicle battery swapping method provided in this application first acquires vehicle status data, and when the vehicle status meets preset conditions, sends a battery swapping start command to a battery swapping station with which a communication connection has been established, so that the battery swapping station can perform the battery swapping operation.

[0082] In this way, the vehicle checks its own status data before the battery swap, avoiding the operation if the vehicle status data does not meet the preset conditions, thus ensuring the normal progress of the battery swap and improving the safety of the swap. Users do not need to get out of the vehicle to check; the onboard terminal can achieve fully automated detection, improving the user's battery swap experience.

[0083] This application does not limit the specific content of the preset conditions, which are crucial for ensuring safe battery swapping. Therefore, as an optional embodiment, the preset conditions may include any one or any combination of the following:

[0084] The steering wheel rotation angle is within a preset angle range;

[0085] The handbrake status indicator signal indicates that the handbrake is in the released state;

[0086] The foot brake status indicator signal indicates that the foot brake is in the released state;

[0087] The gear position indicator signal indicates that the vehicle is in neutral (N) gear.

[0088] Each of the aforementioned door status indicator signals indicates that the corresponding door is in the closed state;

[0089] The power supply connection signal of the vehicle's power unit indicates that the power supply connection of the vehicle's power unit is disconnected;

[0090] The health status data of the battery pack indicates that the health status of the battery pack meets the usage requirements.

[0091] To detect the aforementioned vehicle status data, the vehicle's own sensors and other data acquisition devices can typically be reused. Taking the steering wheel rotation angle as an example, as an optional implementation, let the vehicle's steering wheel sensor reading be N. Typically, based on the steering wheel's rotatable range, the value of N is set to -32767 ≤ N ≤ 32767 (in practice, due to hardware limitations, this boundary value cannot be reached). The steering wheel rotation angle accuracy is 0.1 degrees. Normally, the steering wheel needs to be returned to center, and the determination condition is within ±30 degrees, i.e., -300 ≤ N ≤ 300 is the preset angle range.

[0092] Furthermore, the vehicle's position may need to be slightly adjusted during the subsequent battery swapping process. Therefore, to facilitate this adjustment, it is necessary to ensure that the steering wheel is centered, the handbrake and foot brake are released, and the gear is in neutral (N). Excessive internal vehicle voltage (such as the battery pack voltage) can also pose a safety risk during the battery swapping process; therefore, it is essential to disconnect the power supply to the vehicle's power unit. In some embodiments, to ensure a safe battery swapping process, the battery pack's health status must also meet operational requirements.

[0093] This implementation provides specific data acquisition devices and preset conditions. These devices can collect vehicle status data and reflect the vehicle status of the electric vehicle. Only when the current vehicle status meets these preset conditions will the on-board terminal issue a battery swap start command, thereby ensuring that the battery swap process can be completed safely.

[0094] In practical applications, vehicles may illegally use battery packs, and performing a battery swapping operation in this case may cause safety accidents. Therefore, before the battery swapping operation, the vehicle information and battery pack information are sent to the battery swapping station. The battery swapping station will perform the corresponding battery swapping operation after verifying the vehicle information and battery pack information.

[0095] This embodiment primarily focuses on verifying the legitimacy of the battery pack. As a feasible implementation method, the correspondence between the battery serial number, license plate number, and vehicle battery model can be stored in a cloud server. Verification is successful when the information sent by the vehicle matches the information stored on the cloud server.

[0096] In addition, battery swapping stations may need to provide battery swapping services for different types of vehicles. Therefore, it is necessary to determine the vehicle information and battery pack information of the current vehicle before swapping the battery in order to perform the corresponding operations.

[0097] In this implementation, the on-board terminal sends the electric vehicle's identification information and battery pack information to the battery swapping station in advance. This allows the station to verify the battery pack's legitimacy and ensure the safety of the battery swapping process. The battery swapping station can also perform corresponding battery swapping operations based on the vehicle identification information and battery pack information, ensuring the adaptability of the swapping operations and improving swapping efficiency.

[0098] In practical applications, human error can easily lead to oversights, causing the vehicle's status to deviate from preset conditions. In such cases, it's necessary to prompt the user to adjust the vehicle's status promptly. One feasible approach is to display a corresponding screen on the in-vehicle display panel, reminding the user of the necessary adjustments.

[0099] Figure 2 This is a flowchart illustrating a second vehicle battery swapping method provided in some embodiments of this application.

[0100] like Figure 2 As shown, after acquiring vehicle status data, the method further includes the following steps:

[0101] S104: Output vehicle status information.

[0102] As mentioned above, attempting a battery swap when the vehicle's condition does not meet preset conditions may lead to swap failure or even safety accidents. In such cases, it is necessary to input vehicle status prompts to alert the user to adjust the vehicle promptly if the condition is not met. For example, if a door is not closed, the user could be prompted to close all doors.

[0103] As an optional embodiment, a corresponding interface can be displayed on an in-vehicle display screen to provide prompts. Figure 3 This is a schematic diagram of a first type of vehicle-mounted display screen interface provided for some embodiments of this application. For example... Figure 3 As shown, during the battery swapping preparation phase, after determining the vehicle status based on vehicle status data, a vehicle status prompt information screen 301 can be displayed on the in-vehicle display screen. The content of the vehicle status prompt information screen 301 specifically includes the status of the doors, steering wheel, gear position, handbrake, and foot brake (brake pedal), etc. The screen differentiates between components that meet and do not meet preset conditions, such as... Figure 3 As shown, if the handbrake is not released, the interface will display a corresponding prompt to the user.

[0104] In this implementation, by sending corresponding vehicle status prompts to the user, the user can be reminded to adjust the electric vehicle's status in a timely manner to meet preset conditions. This method can improve the efficiency of battery swapping and enhance the user experience.

[0105] In practical applications, in order to improve the controllability of the battery swapping process, it is necessary to confirm with the user whether a battery swap is required. Here is a specific implementation method. Figure 4 This is a flowchart illustrating a third vehicle battery swapping method provided in some embodiments of this application. Figure 4 As shown, the method specifically includes the following steps:

[0106] S102: Determine whether the vehicle status data meets the preset conditions; if the vehicle status data meets the preset conditions, trigger S1031.

[0107] S1031: Output query information.

[0108] S1032: In response to the user's confirmation input of the query information, send a battery swapping start command to the battery swapping station.

[0109] As mentioned above, the status of various parts of the vehicle can be displayed simultaneously on the in-vehicle display screen, with different displays for parts that meet and do not meet preset conditions. When the status of all parts of the vehicle meets the preset conditions, the in-vehicle display screen will show a query message.

[0110] The inquiry message is used to prompt the user to confirm whether to proceed with the battery swap. As some optional implementations, the inquiry message can be displayed on the vehicle's screen, along with a corresponding input selection box for the user. Alternatively, a "Start Battery Swap" confirmation box can be directly displayed to the user, who, upon clicking the box, confirms their response to the inquiry message.

[0111] Figure 5 This is a schematic diagram of a second type of vehicle display screen interface provided for some embodiments of this application. For example... Figure 5 As shown, during the battery swapping preparation phase, if all parts of the vehicle meet the preset conditions, the in-vehicle display screen will show not only the vehicle status prompt screen 301, but also a confirmation box 302 containing the text "Start Battery Swapping". When the user clicks the confirmation box 302, it indicates that they have submitted confirmation input for the inquiry.

[0112] by Figure 5 Taking the implementation method shown as an example, after the user clicks on the confirmation box that displays "Start Battery Swapping", the vehicle terminal will send a battery swapping start command to the battery swapping station.

[0113] In this implementation, the battery swapping start command will only be issued when the vehicle status meets the preset conditions and the user confirms the start of battery swapping, thus ensuring the controllability of the battery swapping process.

[0114] In practical applications, the battery swapping process may take some time, so users can be prompted at each stage of the battery swapping process. Here is a specific implementation method. Figure 6 This is a flowchart illustrating a fourth vehicle battery swapping method provided in some embodiments of this application. Figure 6 As shown, after sending a battery swap start command to the battery swapping station when the vehicle status meets preset conditions, the method also includes:

[0115] S105: Obtain vehicle battery swapping progress.

[0116] As an optional implementation, the vehicle-mounted terminal can obtain the battery swapping progress from its own sensors and from the battery swapping station to determine the current progress node. Specific progress nodes may include battery swapping start, old battery removal, new battery installation, and battery swapping completion.

[0117] S106: Output battery swapping progress information.

[0118] As a feasible implementation method, progress information can be displayed on an in-vehicle display screen, for example, the progress information can be displayed as a percentage. At the same time, corresponding text prompts can be displayed to the user at each progress node, such as battery swapping started, battery being removed, battery being installed, and battery swapping completed.

[0119] Figure 7 This is a schematic diagram of a third type of vehicle-mounted display screen interface provided for some embodiments of this application. For example... Figure 7 As shown, the vehicle display screen shows a progress information display box 701. After officially entering the battery swapping stage, the progress information display box 701 displays the progress information by percentage to more intuitively show the current battery swapping progress to the user; for example, 40% in the progress information display box 701. In addition, the progress information display box 701 will also display corresponding text prompts to the user under each progress node, such as "Current progress: Battery being removed".

[0120] Figure 8 This is a schematic diagram illustrating a fourth type of vehicle-mounted display screen interface provided in some embodiments of this application. For example... Figure 8 As shown, after the battery swap is completed, the progress information display box 701 shows a percentage of 100% and displays the text "Current progress: Battery swap completed", thus prompting the user to proceed to the next step.

[0121] In this implementation, the battery swapping progress is displayed in real time, allowing users to accurately understand the current battery swapping progress and thus improving the user experience.

[0122] To improve the automation level of battery swapping stations, as an optional implementation method, battery swapping orders can be automatically sent through a cloud server. Figure 9 This is a flowchart illustrating a fifth vehicle battery swapping method provided in some embodiments of this application. Figure 9 As shown, when the vehicle status meets preset conditions, a battery swapping start command is sent to the battery swapping station that has established a communication connection with the vehicle, so that the battery swapping station can perform the battery swapping operation. After that, this solution also includes the following steps:

[0123] S107: Receive and display payment order information for battery swapping orders sent by the cloud server.

[0124] Order information is sent from the battery swapping station to the cloud server, which then generates payment order information based on the order information. As an optional implementation method, the order information may include vehicle identification information (such as license plate number) and battery swapping time, etc.

[0125] S108: Receives payment input from the user for payment order information and makes payment for the battery swapping order.

[0126] In this implementation, battery swapping orders are sent directly to the vehicle terminal via the cloud server, improving payment efficiency and thus enhancing the user experience.

[0127] As mentioned above, a communication connection is established between the vehicle and the battery swapping station when the vehicle enters the station. In order to save communication resources, an optional implementation method is provided here. Figure 10This is a flowchart illustrating a sixth vehicle battery swapping method provided in some embodiments of this application. Figure 10 As shown, when the vehicle status meets preset conditions, a battery swapping start command is sent to the battery swapping station with which the vehicle has established a communication connection, so that the battery swapping station can perform the battery swapping operation. The method also includes:

[0128] S109: Disconnect the communication connection with the battery swapping station if the battery swapping is successful and the vehicle is detected to have left the station.

[0129] In this implementation, the communication connection between the vehicle and the battery swapping station is disconnected when the vehicle leaves the station, thus avoiding long-term occupation of communication resources.

[0130] As an alternative implementation, a battery swapping system framework is provided herein. Figure 11 This is a schematic diagram of the framework of a first vehicle battery swapping system provided for some embodiments of this application. For example... Figure 11 As shown, it includes an on-board terminal 1101, a battery swapping station 1102, and a cloud server 1103; the three establish communication with each other and cooperate to complete the overall battery swapping process.

[0131] by Figure 11 Taking the existing framework as an example, this article also provides an optional implementation method for the overall battery swapping process. Figure 12 This is a schematic diagram illustrating the overall process of vehicle battery swapping provided in some embodiments of this application. For example... Figure 12 As shown, the overall battery swapping process includes the following steps: S1201 to S1222.

[0132] S1201: When a vehicle arrives at the battery swapping station, the station begins scanning the license plate.

[0133] S1202: The battery swapping station uploads the license plate to the cloud server.

[0134] When a vehicle arrives at a battery swapping station, the station will take a photo using a camera at the station entrance to identify the license plate number, and then send the license plate number to the cloud server.

[0135] S1203: Cloud server verifies the legality of license plates.

[0136] S1204: License plate validity verification passed. The cloud server will return the vehicle communication identification information to the battery swapping station.

[0137] The cloud server verifies the legality of the license plate. After the verification is successful, the cloud server returns the vehicle communication identification information to the battery swapping station, that is, it sends the vehicle's Media Access Control (MAC) address and Bluetooth device address resolution key to the battery swapping station.

[0138] S1205: The battery swapping station establishes communication with the on-board terminal based on the vehicle communication identification information sent by the cloud server.

[0139] The battery swapping station establishes a communication connection with the vehicle terminal based on the MAC address and the Bluetooth device address resolution key.

[0140] S1206: The vehicle terminal sends vehicle information and battery pack information to the battery swapping station.

[0141] After establishing a communication connection, the battery swapping station sends a vehicle arrival signal to the on-board terminal. Upon receiving the signal, the on-board terminal sends vehicle information and battery pack information back to the battery swapping station.

[0142] S1207: The battery swapping station opens the entrance gate after the vehicle information and battery pack information have been verified.

[0143] The battery swapping station verifies the vehicle and battery pack information. Once the verification is successful, the entrance gate opens to allow the vehicle to enter. After entering the station, the vehicle drives into the designated battery swapping area and places its wheels into the corresponding battery slots.

[0144] S1208: When the vehicle enters the battery swapping location, the on-board terminal acquires and outputs the vehicle status to the user.

[0145] At this point, the in-vehicle terminal begins acquiring vehicle status data collected by the status acquisition device and determines the vehicle's status based on this data. Simultaneously, the vehicle status is displayed in real-time on the in-vehicle display screen. This allows for the display of vehicle status alerts to the user if the vehicle status does not meet preset conditions, prompting the user to adjust the vehicle accordingly.

[0146] S1209: The on-board terminal sends vehicle status data to the battery swapping station.

[0147] S1210: If the vehicle status data does not meet the preset conditions, the battery swapping station will provide a voice prompt.

[0148] At the same time, the vehicle terminal will synchronize the vehicle status with the battery swapping station, and the battery swapping station will also provide voice prompts if the vehicle status does not meet the preset conditions.

[0149] S1211: When the vehicle status data meets the preset conditions, the battery swapping station requests the vehicle to reduce the high voltage from the on-board terminal.

[0150] If the vehicle status meets the preset conditions, an inquiry message can be displayed to the user. In response to the user's confirmation of the inquiry message, a battery swap start command is sent to the battery swap station. Alternatively, if the vehicle status meets the preset conditions, battery swapping can be started directly (at this time, all vehicle statuses synchronized to the battery swap station meet the preset conditions, which is equivalent to sending a battery swap start command).

[0151] The battery swapping station will then request the vehicle to be de-energized and prohibit it from being re-energized. This is because the battery swapping process requires opening the door, which necessitates sufficient freedom of movement for the vehicle; therefore, the vehicle needs to be de-energized beforehand. Typically, the door is located on the floor at the battery swapping location, and the robotic arm can only extend to remove or install the battery after the door is opened.

[0152] S1212: The vehicle terminal controls the completion of the high-voltage control of the vehicle.

[0153] S1213: The battery swapping station calibrates the vehicle position and opens the door.

[0154] In practical applications, the vehicle's parking position may deviate from the standard position required for battery swapping. In this case, the vehicle's position can be adjusted directly by the robotic arm or other execution equipment at the battery swapping station, improving the accuracy of the battery swapping process and avoiding the need for users to adjust the vehicle's position back and forth.

[0155] S1214: The battery swapping station requests high voltage from the vehicle terminal for the battery pack.

[0156] S1215: The vehicle terminal control of the battery pack has completed the high voltage reduction.

[0157] To ensure the safety of the battery swapping process, the battery pack needs to be subjected to high voltage.

[0158] S1216: The battery swapping station removes the old battery pack, installs the new battery pack, returns the battery swapping equipment to its original position, and closes the opening and closing door.

[0159] Based on vehicle and battery pack information, the battery swapping station performs the corresponding battery swapping operation; that is, removing the old battery pack and installing the new battery pack. After the swapping is completed, the equipment used for the swapping is returned to its original position, and the opening and closing doors are closed.

[0160] S1217: The battery swapping station sends a vehicle self-test request to the on-board terminal.

[0161] S1218: The vehicle terminal has passed the self-test of the vehicle.

[0162] S1219: The battery swapping station allows vehicles to access the high voltage and allows them to pass.

[0163] After the battery swapping station completes the swap, it sends a vehicle self-check request to the on-board terminal to eliminate any potential risks. Once the vehicle self-check is complete, the station allows the vehicle to connect to high voltage and releases it, while simultaneously disconnecting the communication link between the two.

[0164] S1220: The battery swapping station uploads the order information to the cloud server.

[0165] S1221: Generate an order to be paid for on the cloud server.

[0166] S1222: The cloud server sends the order to be paid to the vehicle terminal.

[0167] S1223: The vehicle terminal responds to the user's payment input and makes payment for the pending order.

[0168] After the battery swap is completed, the battery swap station sends the order information to the cloud server. The vehicle terminal receives and displays the payment order information for the battery swap order sent by the cloud server, and processes the payment for the battery swap order after receiving the user's payment input. This completes the entire battery swap process.

[0169] In addition, most vehicles are now equipped with in-vehicle displays. Below are some optional embodiments that can display the various stages of the battery swapping process through the in-vehicle display to prompt users with relevant information.
