Description

Control methods, systems, devices, media, and vehicles for vehicle battery swapping. Technical Field

[0001] This invention relates to the field of automotive control technology, and in particular to a control method, system, device, medium, and vehicle for a vehicle battery swapping mode. Background Technology

[0002] New energy vehicles have gradually entered the industrialization stage due to their green and environmentally friendly nature, low noise, comfort, and low travel costs. In recent years, sales of new energy vehicles have increased year by year. On the one hand, the current ratio of charging piles to new energy vehicles is approximately 1:3, meaning that charging alone cannot meet the energy replenishment requirements of new energy vehicles in the short term. On the other hand, charging piles, currently the most mainstream energy replenishment method for new energy vehicles, suffer from problems such as long charging times, slow speeds, and unreasonable allocation of charging pile resources. In contrast, battery swapping offers faster energy replenishment and can meet the energy replenishment needs of multiple vehicle owners in a short time. Battery swapping is expected to overcome the disadvantages of difficult and slow charging for new energy vehicles, improve energy replenishment efficiency, and become the mainstream energy replenishment method in the future. Against this backdrop, how to safely, quickly, and efficiently complete vehicle battery swapping has attracted widespread attention.

[0005] On one hand, embodiments of the present invention provide a control method for a vehicle battery swapping mode, including:

[0006] Within the network coverage area of ​​the battery swapping station, a communication connection request is sent to the battery swapping station;

[0007] After a successful communication connection is established with the battery swapping station, vehicle identity information is sent to the battery swapping station for vehicle identity verification.

[0060] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The step numbers in the following embodiments are only for ease of explanation and do not limit the order of the steps. The execution order of each step in the embodiments can be adapted according to the understanding of those skilled in the art.

[0061] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., used in the specification, claims, and the foregoing drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatuses.

[0062] 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 belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0063] The following explains some of the technical terms used in this embodiment.

[0064] Service-Oriented Architecture (SOA) is a component model that connects different functional units of an application (called services) through well-defined interfaces and contracts between these services. These interfaces are defined in a neutral manner, independent of the hardware platform, operating system, and programming language used to implement the services. This allows services built on various such systems to interact in a unified and universal way.

[0065] VDC (Vehicle Dynamics Control) organically integrates the control systems of major vehicle assemblies, such as braking, drive, suspension, steering, and engine, in terms of function and structure. This allows the vehicle to maintain excellent directional stability and exhibit optimal driving performance under various adverse conditions, such as on icy or snowy roads, on winding roads, and when performing evasive maneuvers like lane changing, braking, acceleration, and downhill driving. When the vehicle experiences wheel slippage, tilting, or loss of traction, the VDC system immediately intervenes, reducing engine speed and selectively applying braking control to individual wheels, ultimately guiding the vehicle back onto its normal driving path and preventing dangers caused by loss of control.

[0066] The CSC (Cell Supervision and Collection) mainly consists of sensors, control units, and actuators. Sensors detect the vehicle's status, such as speed, lateral acceleration, and steering wheel angle, and transmit this data to the control unit. The control unit analyzes this data to determine if there is a potential risk of loss of control, such as skidding or rollover. Then, it uses actuators to adjust the vehicle's stability, such as braking a wheel or adjusting steering force, to ensure vehicle stability and safety.

[0067] Standby mode refers to a state where the vehicle automatically enters a state with very low power consumption after the engine has been off for a period of time; it is also known as "low-energy mode" or "standby mode." In this mode, the equipment or system is on, but no task or operation is being performed. The equipment or system typically maintains a certain level of energy consumption in order to be ready to perform tasks or operations at any time.

[0068] Parking Distance Control (PDC, also known as reversing radar) systems can detect obstacles in front of and behind the vehicle using ultrasonic signals, and issue audible, visual, or visual alarms when necessary. Early models' parking distance control systems could only use sound generators for alarms. However, with the development of vehicle network technology, the alarm methods for parking distance control systems have been greatly improved. They can now issue audible alarms via the audio system's horn or visual alarms via the central information display (or in-vehicle display).

[0069] The HCU (Hybrid Control Unit) is the ABS actuator, typically consisting of a boost valve (normally open), a pressure reducing valve (normally closed), a return pump, and an accumulator. The boost and pressure reducing valves are controlled by ECU signals to open and close the hydraulic circuit, thus achieving the braking processes of normal, pressure-holding, pressure-reducing, and boosting. The electric pump, composed of a plunger-type oil pump and a drive motor, primarily maintains a certain pressure of brake fluid in the accumulator.

[0070] A BMS (Battery Management System) is a system that monitors and controls batteries, providing real-time feedback of collected battery information to users and adjusting parameters based on the collected information to fully utilize battery performance. The BMS battery management system performs the following functions: (1) Measurement of battery terminal voltage; (2) Energy balancing between individual cells: equal charging of individual cells to ensure that all cells in the battery pack reach a balanced state; (3) Measurement of total battery pack voltage; (4) Measurement of total battery pack current; (5) SOC calculation: accurately estimating the state of charge (SOC) of the power battery pack, i.e., the remaining battery capacity, ensuring that the SOC is maintained within a reasonable range, and preventing damage to the battery due to overcharging or over-discharging; (6) Dynamic monitoring of the working status of the power battery pack: during the charging and discharging process, the terminal voltage and temperature of each cell in the battery pack, the charging and discharging current and the total voltage of the battery pack are collected in real time to prevent overcharging or over-discharging of the battery; (7) Real-time data display; (8) Data recording and analysis: identifying problematic cells to maintain the reliability and efficiency of the entire battery pack operation; (9) Communication networking function.

[0071] ICC (Integrated Adaptive Cruise Control) is an advanced driver assistance technology designed to enhance driving convenience and safety. Within a certain speed range, this system provides adaptive cruise control and lane-keeping assist, enabling semi-autonomous driving on highways or elevated roads in good conditions. When ICC is activated, it automatically controls the vehicle's acceleration, deceleration, and braking based on the set speed and distance to the vehicle ahead, maintaining a safe following distance. Simultaneously, the system uses sensors such as cameras and radar to identify lane markings and automatically control the vehicle's steering, ensuring it remains centered within its lane.

[0072] EPB (Electrical Park Brake) is a technology that integrates temporary braking during driving and long-term braking after parking, and uses electronic control to achieve parking braking.

[0073] Referring to Figure 1, the vehicle refers to the vehicle waiting for battery swapping, and the battery swapping station refers to the station that provides the vehicle's battery. A communication connection is established between the vehicle and the battery swapping station, and they can exchange information. The vehicle can send its own information to the battery swapping station, and the battery swapping station can send station information and battery swapping instructions to the vehicle.

[0074] As shown in Figure 2, this embodiment of the invention provides a control method for a vehicle battery swapping mode, which is applied to a vehicle and includes steps S100 to S400.

[0075] S100. Within the network coverage area of ​​the battery swapping station, send a communication connection request to the battery swapping station.

[0076] Before swapping batteries, vehicles need to be within the network coverage area of ​​the battery swapping station, such as a WIFI network. If a vehicle wants to swap batteries, it will automatically establish a connection within the WiFi range of the battery swapping station. After the user drives the vehicle into the parking waiting area, the vehicle can automatically detect whether it has entered the parking waiting area of ​​the battery swapping station based on the connection status of the battery swapping station.

[0077] The vehicle's infotainment system needs to initiate a Wi-Fi request to the battery swapping station. When the station detects this request, it verifies the Wi-Fi SSID (Service Set Identifier) ​​and key. The infotainment system obtains the station's IP / PORT, Wi-Fi SSID, and key information from the TSP (Telematics Service Provider) to establish a Wi-Fi connection. Using the vehicle's navigation system to reach the station automatically triggers the connection; otherwise, the user must manually initiate the connection. Once verification is successful, the infotainment system can communicate with the station and display connection information.

[0078] After the S200 successfully establishes a communication connection with the battery swapping station, it sends vehicle identity information to the station for vehicle identity verification.

[0079] After the communication connection between the vehicle and the battery swapping station is successfully established, the vehicle sends its identity information to the station. The station verifies the vehicle's identity information and sends the verification result back to the vehicle so that it can perform subsequent actions.

[0080] S300: If the vehicle identity information sent by the battery swapping station is verified to be valid, the vehicle status information is periodically uploaded to the battery swapping station, and the battery swapping station status information or battery swapping request information sent by the battery swapping station is received and displayed; the battery swapping request information is determined based on the vehicle status information.

[0081] If the vehicle's identity information is verified, the vehicle's infotainment system receives a valid identity confirmation message from the battery swapping station. The system then periodically uploads vehicle status information to the station. The battery swapping station periodically sends its own status information to the vehicle's infotainment system. Simultaneously, based on the periodic vehicle status information from the vehicle's infotainment system, the station determines that it can enter battery swapping mode and pushes a battery swapping request to the vehicle's infotainment system, which then displays the battery swapping request page.

[0082] S400: If a battery swapping request is received, determine whether the vehicle speed is within the preset range. If the vehicle speed is within the preset range, activate the battery swapping mode and control the vehicle's internal controller to operate in the preset state until the battery swapping is completed, then exit the battery swapping mode.

[0083] If the vehicle's terminal receives a battery swapping request from the battery swapping station, it determines whether the vehicle speed is within the preset range. If the vehicle speed is within the preset range, the battery swapping mode is activated, and the internal controllers are controlled to operate in the preset state until the battery swapping is completed, at which point the battery swapping mode is exited. If the vehicle speed is not within the preset range, the battery swapping mode is not activated.

[0084] It should be noted that the preset range is determined based on the actual application, and this embodiment does not impose specific limitations. For example, VDC determines whether the current vehicle speed is less than 3 km / h; if the current vehicle speed is less than 3 km / h, the battery swapping mode is activated.

[0085] It should be noted that the method for activating the battery swapping mode is determined based on the actual application, and this embodiment does not impose specific limitations. The preset operating states of each controller within the vehicle during battery swapping mode are determined based on the actual application, and this embodiment does not impose specific limitations.

[0086] Referring to Figure 7, the CSC will synchronize information regarding whether the VDC agrees to enter battery swapping mode to the battery swapping station. Throughout the entire battery swapping process, the vehicle's terminal must maintain a connection with the battery swapping station via Wi-Fi. Once the battery swapping is complete, the station will send a notification to the vehicle's terminal to inform it that the swapping is finished. When the vehicle is in battery swapping mode and the station has completed the swapping operation, the CSC receives the battery swapping completion signal from the station's wireless device. The VDC then receives the battery swapping switch exit signal from the CSC, the vehicle powers on at low voltage and completes its self-test, notifying the CSC that the swapping is complete, and the vehicle exits battery swapping mode.

[0087] Optionally, referring to Figure 3, the control method further includes:

[0088] S210. If the communication connection with the battery swapping station is not successfully established, send a first preset number of communication connection requests to the battery swapping station at a first time interval.

[0089] S211. Send a communication connection request to the battery swapping station at the second time interval until the communication connection is successfully established.

[0090] If the communication connection between the vehicle and the battery swapping station fails to be established, the vehicle continuously sends communication connection requests to the station. First, the vehicle's terminal sends a first preset number of communication connection requests to the station at a first time interval. If the communication still fails to establish a connection, it sends communication connection requests to the station at a second time interval, until the communication connection is successfully established. It should be noted that the first time interval is shorter than the second time interval. Those skilled in the art will understand that the specific values ​​of the first and second time intervals are determined based on actual applications, and this embodiment does not impose specific limitations.

[0091] In one specific embodiment, the vehicle-mounted terminal first attempts to initiate a communication connection request every 200ms. If the number of consecutive connection attempts exceeds 10 and the vehicle-mounted terminal still fails to establish a communication connection with the battery swapping station, the vehicle-mounted terminal continues to send a communication connection request to the battery swapping station every 1s until the vehicle-mounted terminal and the battery swapping station platform successfully establish a communication connection.

[0092] Optionally, referring to Figure 4, vehicle identification information is sent to the battery swapping station, specifically including:

[0093] S201, Receive vehicle identity request information sent by the battery swapping station;

[0094] S202. Send vehicle identity information to the battery swapping station based on the vehicle identity request information.

[0095] After the vehicle establishes a communication connection with the battery swapping station, the battery swapping station sends a vehicle identity request to the vehicle; the vehicle sends its own vehicle identity information to the battery swapping station based on the vehicle identity request; after receiving the vehicle identity information, the battery swapping station verifies the vehicle identity information and sends the verification result to the vehicle.

[0096] In one specific embodiment, after the near-field communication connection between the vehicle and the battery swapping station is completed, the battery swapping station requests vehicle identity-related information from the vehicle's terminal. The vehicle's terminal needs to respond to the request and send vehicle identity information, such as license plate number, VIN code, and vehicle model information, to the battery swapping station.

[0097] Optionally, referring to Figure 5, the battery swapping mode can be activated, specifically including:

[0098] S401A, Check if the vehicle is in standby mode;

[0099] S402A: If the vehicle is in standby mode, obtain battery swap confirmation and user information confirmation, and display safety operation prompts.

[0100] S403A: When the vehicle meets the conditions for entering the battery swapping process, control the vehicle to switch off the high voltage and set the battery swapping mode signal to active.

[0101] Referring to Figure 7, in one specific embodiment, the user enters the charging application interface on the central control screen and can click to enter and exit the battery swapping mode. The central control interface displays the latest battery swapping mode. The CSC needs to detect that the vehicle status is in standby mode before entering the battery swapping mode. In non-standby mode, the battery swapping button is grayed out. When the user enters the battery swapping mode, the central control interface will ask the user for secondary confirmation, prompting the user that "Battery swapping is about to begin. Please release the brake after parking. Do not perform any operations during the battery swapping process." If the user selects to confirm the current battery swapping mode, the CSC will send a battery swapping switch signal to the VDC.

[0102] The vehicle's infotainment system interacts with the battery swapping station via signals. The station identifies the vehicle's identity information and verifies its legitimacy a second time. When the vehicle's infotainment system receives a message indicating that the battery swapping station's verification has failed, it cannot perform the battery swapping operation. Only after receiving a message indicating that the verification has passed will the vehicle's infotainment system periodically report the vehicle's status related to battery swapping at preset time intervals, such as every 1 second. When the status changes, an event is triggered once.

[0103] After the PDC determines that the battery swap reminder signal is valid, it sends the battery swap reminder signal to the VDC. After receiving the battery swap reminder signal, the VDC activates the mode and enters the battery swap process. When the vehicle detects that the judgment conditions are met and enters the battery swap mode, the VDC controls the vehicle to first disconnect the high voltage power. After the high voltage power is disconnected, the battery swap mode signal is set to valid. The VDC (HCU) sends the battery swap mode signal to the VDC (power mode), PDC, MCU, CSC, BMS, ICC, and EPB, and each controller enters the battery swap mode.

[0104] Optionally, referring to Figure 6, the battery swapping mode can be activated, specifically including:

[0105] S401B: Obtain the battery swapping mode entry operation and display safety operation prompts;

[0106] S402B controls the electronic parking brake system to be in the released state, issues a low-voltage power-off request, and enters the battery swapping mode.

[0107] In one specific embodiment, the central control system sets the battery swapping mode to a soft button. After pressing the button, a confirmation box pops up. After the user clicks to confirm, the CSC sets the battery swapping switch signal to "2-Battery Swapping Mode" and displays a text prompt.

[0108] Referring to Figure 7, VDC sends a battery swapping EPB release request to PDC, and VDC sends a non-automatic return to P position. After receiving the battery swapping EPB release request, if PDC (EPB) is in the clamped state, it releases EPB. VDC sends an EPB release request, and after receiving the EPB release status signal, it sends a low-voltage power-down request (battery swapping low-voltage power-down request signal) to VDC (power mode).

[0109] Optionally, referring to Figure 7, the internal controllers are controlled to operate in preset states, specifically including:

[0110] S411, controls the hybrid power controller to store battery swapping mode signals, shield fault signals, and suspend high-voltage power-on process;

[0111] S412, and / or, control the vehicle's low-voltage power-off state of the electronic parking brake system and the self-clamping of the electronic parking brake system after power-off;

[0112] S413, and / or, control the parking distance control system and microcontroller to shield the battery management system node loss fault signal;

[0113] S414, and / or, control the battery management system to control its own information and fault information.

[0114] The status of each controller when entering battery swapping mode:

[0115] (1) VDC (HCU): The vehicle is in battery swapping mode and does not respond to other high-voltage power-on requests. During the battery swapping process, VDC stores the battery swapping mode signal and cannot enter the high-voltage power-on process. It shields the BMS node loss fault and the battery swapping lock abnormal fault. After exiting the battery swapping mode, it can still be diagnosed normally.

[0116] (2) PDC (EPB): In battery swapping mode, when the vehicle is in a low-voltage power-off state, the EPB power-off self-clamping is prohibited (in battery swapping mode, if a manual EPB switch operation is received, the manual command must be responded to).

[0117] (3) PDC: In battery swapping mode, the BMS node loss fault is masked. After exiting battery swapping mode, it can still be diagnosed normally.

[0118] (4) MCU: In battery swapping mode, the BMS node loss fault is masked. After exiting battery swapping mode, it can still be diagnosed normally.

[0119] (5) BMS: Upon receiving a valid battery swapping status signal, it enters battery swapping mode and stores its own information and fault information.

[0120] (6) CSC: Upon receiving a valid battery swapping status signal, turn on the switch light and forward it to the battery swapping station.

[0121] (7) VDC (Power Mode): In battery swapping mode, the vehicle will be powered down when a low-voltage power-down request is received.

[0122] Implementing the embodiments of the present invention has the following beneficial effects: When a vehicle is within the network coverage area of ​​a battery swapping station, it sends a communication connection request to the station via the network to achieve information interaction between the vehicle and the station; after the communication connection between the vehicle and the station is successfully established, the vehicle identity information is verified between the vehicle and the station to ensure the legitimacy of the vehicle's identity information; if the vehicle identity information received from the station is verified as valid, the vehicle status information is periodically uploaded to the station so that the station can determine whether the vehicle is suitable for entering the battery swapping mode based on the vehicle status information, thereby improving security; if it is suitable for entering the battery swapping mode, the vehicle receives the battery swapping request information from the station; if the battery swapping request information is received, the vehicle determines whether its speed is within a preset range; if the speed is within the preset range, the battery swapping mode is activated to improve the safety of the vehicle's battery swapping, and the internal controllers are controlled to operate in preset states until the battery swapping is completed, at which point the vehicle exits the battery swapping mode, further controlling the operating state of the vehicle's internal controllers to improve the stability of the battery swapping process; after the vehicle identity verification is passed, if it is determined that the vehicle status information is suitable for entering the battery swapping mode, the battery swapping mode is activated, and the battery swapping operation is performed in real time, thereby completing the vehicle's battery swapping quickly and efficiently.

[0123] Referring to Figure 8, an embodiment of the present invention provides a control system for a vehicle battery swapping mode, including:

[0138] Referring to Figure 1, an embodiment of the present invention provides a control system for a vehicle battery swapping mode, including a vehicle and a battery swapping station, with a communication connection between the vehicle and the battery swapping station; wherein,

[0139] A battery swapping station is used to receive vehicle identity information sent by a vehicle, verify the vehicle identity information, determine whether to enter battery swapping mode based on vehicle status information, and send battery swapping station status information or battery swapping request information to the vehicle.

[0140] The vehicles include:

[0141] At least one processor;

[0142] At least one memory for storing at least one program;

[0143] When at least one program is executed by at least one processor, the at least one processor performs the method described above.

[0144] First, after establishing a communication connection between the vehicle and the battery swapping station, the station verifies the vehicle's identity information. Once the vehicle identity is verified, the station assesses the vehicle's status information to determine if it is suitable to enter battery swapping mode. If the vehicle's status is suitable, the vehicle's infotainment system sends a confirmation to the station to activate battery swapping mode, controlling all internal controllers to operate in preset states until battery swapping is complete. Then, the vehicle exits battery swapping mode, and all internal controllers return to normal control mode.

[0145] It is evident that the content of the above method embodiments is applicable to this system embodiment. The specific functions implemented in this system embodiment are the same as those in the above method embodiments, and the beneficial effects achieved are also the same as those achieved in the above method embodiments.

[0146] Optionally, referring to Figure 10, the control system also includes a vehicle cloud platform and a terminal, with the terminal communicating with the vehicle cloud platform and the vehicle cloud platform communicating with the vehicle.

[0147] The vehicle cloud platform can acquire various vehicle-related information, such as vehicle identity and status information. Simultaneously, the vehicle cloud platform can also send control signals to the vehicle. Terminals communicate with the vehicle through the vehicle cloud platform to acquire relevant vehicle information and remotely control the vehicle. Remote control of the vehicle via the terminal is convenient and quick. Specifically, terminals include, but are not limited to, mobile phones, tablets, computers, or wearable devices.

[0148] Optionally, referring to Figure 11, the control system also includes a battery swapping station cloud platform, with the vehicle cloud platform communicating with the battery swapping station cloud platform and the battery swapping station cloud platform communicating with the battery swapping station.

[0149] The battery swapping station cloud platform can obtain relevant information from multiple battery swapping stations, such as the available battery models, remaining available batteries, and the utilization rate of waiting areas at each station. The cloud platform establishes a communication connection with the vehicle cloud platform, enabling communication between the terminal and the swapping station. The cloud platform can construct map information and reservation resource information for multiple swapping stations, allowing the terminal to pre-book battery swapping services through the vehicle cloud platform. This reduces battery swapping waiting time, further saving user time and improving swapping efficiency. Additionally, users can also pre-book battery swapping services through the vehicle's operating system via both the vehicle cloud platform and the battery swapping station cloud platform.

[0150] Specifically, referring to Figure 12, a user makes a reservation through a terminal app. The user's terminal app sends the reservation order to the vehicle cloud platform, which forwards the reservation order to the battery swapping station cloud platform. The battery swapping station cloud platform then forwards the reservation order to the battery swapping station. The battery swapping station processes and accepts the reservation order and forwards the reservation result to the vehicle through both the battery swapping station cloud platform and the vehicle cloud platform. The reservation result includes the battery swapping station's service IP / PORT, WIFI SSID, and key. Similarly, a user makes a reservation in a vehicle. The vehicle sends the reservation order to the vehicle cloud platform, which forwards the reservation order to the battery swapping station cloud platform. The battery swapping station cloud platform then forwards the reservation order to the battery swapping station. The battery swapping station processes and accepts the reservation order and forwards the reservation result to the vehicle through both the battery swapping station cloud platform and the vehicle cloud platform.

[0151] This invention also provides a vehicle, which includes an electric drive assembly comprising the aforementioned control system or control device. Specifically, the vehicle can be a private car, such as a sedan, SUV, MPV, or pickup truck. The vehicle can also be a commercial vehicle, such as a van, bus, small truck, or large trailer.
