Description

Technical Field

[0001] This application relates to the field of water-based mobile equipment technology, and in particular to a control method, a control system, a water-based propulsion device, and an electronic device. Background Technology

[0002] A water propulsion system, such as an outboard motor, is a detachable power unit suspended from the stern of a boat or other mobile aquatic device, propelling it forward. A water propulsion system typically includes a battery unit, a controller (such as an Electronic Control Unit, ECU), and a power unit (such as a Power Control Unit, PCU), which includes a motor driver and a motor. The battery unit provides high-voltage power to the power unit to drive the propulsion and low-voltage power to the controller to maintain system control functions.

[0003] Water propulsion systems sometimes require emergency power-off during operation. For example, if the control panel (interaction unit, such as the throttle handle) buttons experience mechanical failure or signal transmission failure, the user must quickly disconnect the power to ensure safety.

[0004] In related technologies, emergency power-off is typically achieved by the user directly operating a physical switch on the battery unit (such as a battery button or main switch). In this case, the battery unit immediately disconnects all output power, causing the entire system to lose power instantaneously.

[0005] While this emergency power-off method can quickly cut off the power supply to ensure safety, it has a significant drawback: due to the instantaneous power loss, the controller cannot save critical operating data (such as mileage, motor load curves, alarm records, etc.) in a timely manner, resulting in the irrecoverable loss of this data. This not only affects the user experience but also makes subsequent equipment status monitoring, maintenance, and fault diagnosis difficult. Summary of the Invention

[0006] This application provides a control method, a control system, a water propulsion device, and an electronic device.

[0007] In a first aspect, this application provides a control method applied to a battery cell, wherein the battery cell is connected to a controller and a power unit, and the method includes: Receive the first electrical signal; In response to the first power-down signal, a second power-down signal is sent to the controller; If a third power-down signal is received from the controller based on the second power-down signal within a predetermined time, the high-voltage power supply output to the power unit is disconnected. If the third power-down signal is not received within the predetermined time, the high-voltage power supply and the first low-voltage power supply output to the controller will be disconnected.

[0008] Secondly, this application provides a control system, including: The battery unit is configured to receive a first power-off signal, and in response to the first power-off signal, send a second power-off signal to the controller. If a third power-off signal is received from the controller based on the second power-off signal within a predetermined time, the high-voltage power supply output to the power unit is disconnected. If the third power-off signal is not received within the predetermined time, the high-voltage power supply and the first low-voltage power supply output to the controller are disconnected. The controller is used to connect to the first low-voltage power supply output by the battery unit, receive the second power-off signal sent by the battery unit, and feed back a third power-off signal to the battery unit. A power unit is used to connect to the high-voltage power supply.

[0009] Thirdly, this application provides a water propulsion device, including the control system provided in the second aspect above.

[0010] Thirdly, this application provides an electronic device, including a processing component and a storage component; The storage component stores a computer program; the computer program is invoked and executed by the processing component to implement the control method provided in the first aspect above.

[0011] In this embodiment, when the battery unit receives the first power-down signal, it first responds by sending a second power-down signal to the controller, thus providing the controller with an opportunity to perform an orderly power-down operation. Subsequently, it performs tiered processing based on whether a third power-down signal is received from the controller within a predetermined time. If the third power-down signal is received, only the high-voltage power supply to the power unit is disconnected; if not received, both the high-voltage power supply and the first low-voltage power supply to the controller are disconnected simultaneously. This ensures that, under normal controller operation, a smooth transition similar to a normal power-down can be achieved through the collaborative mechanism between the battery unit and the controller. The controller can promptly save current critical operating data (such as mileage, motor load curves, alarm records, etc.) to prevent irrecoverable data loss. In the event of a controller failure, a forced full power-off is executed promptly to prioritize system safety. This tiered response and controller-coordinated buffering power-down method achieves intelligent control of emergency power-downs, avoiding the harsh handling of instantaneous power loss. It allows critical operating data to be retained in fault scenarios, effectively improving the user experience and facilitating subsequent equipment status monitoring, maintenance, and fault diagnosis, thereby enhancing the overall reliability and practicality of the water propulsion system.

[0012] These or other aspects of this application will become more apparent in the following description of the embodiments. Attached Figure Description

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Figure 1The flowchart illustrates an embodiment of a control method provided in this application. This method can be executed by a battery cell connected to a controller and a power unit. The battery cell can refer to a core component providing power management, such as a high-voltage battery pack or a unit within an integrated battery management system (BMS). Its main functions include outputting high-voltage and low-voltage power and supporting communication with the controller. The controller can refer to a control center, such as a system electronic control unit, responsible for handling control logic, data management, and power distribution. The power unit can refer to a component that receives high-voltage power to generate propulsion power, such as a combination of a motor driver, a motor, and a propeller.

[0017] like Figure 1 As shown, the method may include the following steps: 101: Receive the first power-down signal; 102: In response to the first power-down signal, send a second power-down signal to the controller; If a third power-down signal is received from the controller based on the second power-down signal within a predetermined time, then step 103 is executed: disconnect the high-voltage power supply output to the power unit; otherwise, step 104 is executed: disconnect the high-voltage power supply and the first low-voltage power supply output to the controller.

[0018] In embodiments of this application, the battery cell may receive a first power-down signal. The first power-down signal may refer to an initial input signal that triggers the power-down process.

[0019] The first power-down signal can originate from direct user operation of the battery unit, such as triggering it via a physical button or switch on the battery unit, or it can be an external trigger signal received through other input interfaces. When the normal power-down path (such as a power-off command sent via the control panel) becomes unavailable due to a malfunction, a power-down request can be initiated through this first power-down signal, thereby providing the system with a backup power-down triggering method.

[0020] Upon receiving the first power-down signal, the battery cell immediately responds and sends a second power-down signal to the controller. This second power-down signal can be a power-down request command actively issued by the battery cell, such as a message frame conforming to a specific communication protocol (e.g., the CAN bus protocol), or other digital signal forms. Its purpose is to notify the controller to initiate an orderly power-down process, thereby providing the controller with an opportunity to perform orderly power-down operations. This includes saving current critical operating data (such as mileage, load curves, alarm records, etc.) and performing necessary shutdown preparations, thus providing a buffer opportunity for subsequent power cut-off.

[0021] The battery cell then judges the controller's response.

[0022] If a third power-down signal is received from the controller within the predetermined time based on the second power-down signal, it indicates that the controller is working normally, has successfully completed the orderly power-down preparation, and has actively requested to disconnect the high-voltage power supply. In this case, the battery unit will only disconnect the high-voltage power supply output to the power unit.

[0023] In the embodiments of this application, the predetermined time refers to the waiting time limit used to evaluate the controller's response capability, for example, it can be 300ms to 1s, preferably 500ms, to ensure sufficient buffering while avoiding excessive delay.

[0024] The third power-down signal refers to the acknowledgment or request signal returned by the controller. For example, it could be a specific message sent by the controller after completing data saving operations, indicating that it is ready to disconnect the high-voltage power supply. The high-voltage power supply refers to the high-voltage power supplied by the battery unit to the power unit; for example, it could be a DC power supply of several hundred volts used to drive the motor and generate propulsion. At this time, disconnecting only the high-voltage power supply while maintaining the low-voltage power supply to the controller allows the system to smoothly enter standby mode, preserving the integrity of critical operating data (such as mileage, load curves, and alarm records) to the greatest extent possible.

[0025] Conversely, if no third power-down signal is received within the predetermined time, the battery cell simultaneously disconnects the high-voltage power supply to the power unit and the first low-voltage power supply to the controller. In the embodiments of this application, the first low-voltage power supply refers to the auxiliary low-voltage power supply provided by the battery cell to the controller, such as a 12V or 24V DC power supply, used to maintain the basic operation of the controller. If no third power-down signal is received within the predetermined time, it indicates that the controller may have a fault (such as hardware damage or serious abnormality) and cannot complete the orderly power-down. In this case, a complete forced power-off is prioritized to prevent potential safety hazards caused by the continuous output of high-voltage power.

[0026] In this embodiment, when the battery unit receives the first power-down signal, it first responds by sending a second power-down signal to the controller, thus providing the controller with an opportunity to perform an orderly power-down operation. Subsequently, it performs tiered processing based on whether a third power-down signal is received from the controller within a predetermined time. If the third power-down signal is received, only the high-voltage power supply to the power unit is disconnected; if not received, both the high-voltage power supply and the first low-voltage power supply to the controller are disconnected simultaneously. This ensures that, under normal controller operation, a smooth transition similar to a normal power-down can be achieved through the collaborative mechanism between the battery unit and the controller. The controller can promptly save current critical operating data (such as mileage, motor load curves, alarm records, etc.) to prevent irrecoverable data loss. In the event of a controller failure, a forced full power-off is executed promptly to prioritize system safety. This tiered response and controller-coordinated buffering power-down method achieves intelligent control of emergency power-downs, avoiding the harsh handling of instantaneous power loss. It allows critical operating data to be retained in fault scenarios, effectively improving the user experience and facilitating subsequent equipment status monitoring, maintenance, and fault diagnosis, thereby enhancing the overall reliability and practicality of the water propulsion system.

[0027] In some embodiments, receiving the first electrical signal can be specifically implemented as follows: Receives the first power-down signal generated by triggering the power button on the battery unit.

[0028] In one embodiment of this application, the step of the battery cell receiving the first power-down signal can be specifically implemented as receiving the first power-down signal generated by triggering the power button of the battery cell. In this embodiment, the power button refers to a physical operating element disposed on the battery cell, such as a mechanical button, touch button, or rotary switch. Its design purpose is to provide the user with a direct and accessible hardware trigger interface, facilitating a quick initiation of a power-down request when the normal power-down path fails. This power button is typically located on the surface of the battery cell's casing or in an easily accessible position to ensure convenient operation by the user in both emergency and routine scenarios.

[0029] When a user triggers the power button, such as by pressing, holding, or rotating it, the battery cell's internal control circuitry or embedded processor detects the corresponding electrical signal change, generating and recognizing it as the first power-down signal. This first power-down signal can be a digital level change (such as a transition from high to low), a pulse signal, or a specifically coded input. It can be reliably captured, for example, through debouncing processing and signal sampling logic in the button circuitry, avoiding false triggering. This implementation directly binds the source of the first power-down signal to the battery cell's own hardware components, independent of controller or interaction unit failures, thus providing the system with an independent backup power-down trigger mechanism.

[0030] This method of triggering the first power-down signal simplifies and simplifies the reception process, eliminating the need for external communication or complex sensors. The signal can be received solely through the built-in button detection module within the battery cell. Those skilled in the art can implement this design based on existing battery management system hardware, for example, by connecting the button circuit to the GPIO pins of a microcontroller (such as an MCU) and programming corresponding interrupt service routines in the firmware to respond to the trigger event. This design not only improves the robustness of the power-down operation but also maintains the overall simplicity of the system. In some embodiments, receiving the first power-down signal generated by triggering the power button of the battery unit can be specifically implemented as follows: Receives a first power-down signal generated by triggering the power button of the battery unit for more than a first preset time.

[0031] In the embodiments of this application, the first preset duration refers to a preset threshold for the duration of button press, such as 2 to 5 seconds, preferably 3 seconds, to distinguish between intentional power-off operation and brief accidental or accidental touch.

[0032] This improves operational reliability, prevents accidental power-down processes caused by users accidentally touching buttons, reduces the risk of misoperation, and ensures that users can quickly and clearly initiate power-down requests when needed.

[0033] When a user presses the power button, the battery cell's internal control module continuously monitors the button's status, for example, by tracking the duration of the button press in real time using a timer or counter. Specifically, if the button is pressed for less than a first preset duration, the battery cell considers it a normal touch or an invalid operation and does not generate a first power-down signal; only when the button press duration exceeds the first preset duration is the battery cell generated and recognized as a valid first power-down signal.

[0034] Since boats may experience shaking or accidental collisions during operation, the long-press button mechanism can effectively filter out these interfering factors and provide a more stable user interaction experience.

[0035] In some embodiments, if no third power-down signal is received within a predetermined time, after disconnecting the high-voltage power supply and the low-voltage power supply output to the controller, the method may further include: Detect the duration of disconnection of the first low-voltage power supply; If the disconnection period reaches the second preset duration, the first low-voltage power supply is output to the controller again.

[0036] In some embodiments, when the battery cell does not receive a third power-off signal within a predetermined time and thus performs a forced power-off operation, the control method may further include detecting the disconnection duration of the first low-voltage power supply, and re-outputting the first low-voltage power supply to the controller when the disconnection duration reaches a second preset duration, thereby providing an automatic recovery mechanism for the system.

[0037] In the embodiments of this application, the first low-voltage power supply, as described above, is an auxiliary low-voltage power supply provided by the battery unit to the controller. Its disconnection will cause the controller to be completely powered down. The second preset duration refers to a pre-set threshold for the duration of low-voltage power supply disconnection, for example, it can be 5 to 30 seconds, preferably 10 to 20 seconds. This duration is designed to ensure that the controller has sufficient discharge and reset buffer time in soft fault scenarios, while avoiding excessive waiting time that would affect the user experience.

[0038] Specifically, after the battery cell simultaneously disconnects the high-voltage power supply and the first low-voltage power supply, its internal control module starts a timer or counter to continuously monitor the duration of the first low-voltage power supply disconnection. This monitoring process can be based on the battery cell's embedded processor tracking the time from the moment of disconnection in real time, for example, through hardware timer interrupts or software loop polling to achieve accurate timing. If the disconnection duration has not yet reached the second preset duration, the battery cell maintains the disconnected state of all power supplies to completely cut off the system power supply and ensure safety first; only when the detected disconnection duration reaches or exceeds the second preset duration will the battery cell automatically resume outputting the first low-voltage power supply, and simultaneously, depending on the system design requirements, the output preparation of the high-voltage power supply can be restored, thereby enabling the controller to power on again and attempt to start.

[0039] The automatic recovery mechanism can be used to address temporary soft faults in the controller (such as a program malfunction causing a freeze or loop). A brief, complete power-down is often sufficient to clear the abnormal state, enabling the controller to self-reset and recover without manual user intervention. This mechanism enhances the system's robustness and self-healing capabilities. In applications such as aquatic propulsion systems, where temporary software problems occur during navigation, the system can automatically resume normal operation after a short pause, avoiding frequent manual restarts or maintenance needs.

[0040] In some embodiments, if no third power-down signal is received within a predetermined time, after disconnecting the high-voltage power supply and the low-voltage power supply output to the controller, the method further includes: Receive the first power-on signal; In response to the first power-on signal, a first low-voltage power supply is output to the controller so that the controller can perform a reset and recovery based on the first low-voltage power supply.

[0041] In embodiments of this application, the first power-on signal can refer to an input signal used to trigger the system to power on again. For example, it can be an electrical signal generated by the user operating the power button on the battery cell again, or it can include external commands received through different operating methods of the same physical switch (such as a short press or another long press) or a backup interface. The first power-on signal can be actively initiated by the user after a forced power-off, with the aim of restarting the controller to restore the controller from being unresponsive due to a soft fault.

[0042] After the battery cell disconnects the high-voltage power supply and the first low-voltage power supply, its internal control module maintains monitoring of the input signals. Upon detecting the first power-on signal, the battery cell immediately responds and re-outputs the first low-voltage power supply to the controller. This first low-voltage power supply, as before, is an auxiliary low-voltage power supply used to maintain the basic operation of the controller. At this time, after regaining power, the controller executes the standard power-on initialization procedure, such as clearing temporary abnormal states, reloading programs, or resetting internal registers, thereby achieving self-recovery and returning to normal operating status. Simultaneously, according to the system design, the battery cell can further wait for subsequent instructions from the controller after outputting the first low-voltage power supply before deciding whether to restore the high-voltage power supply output, ensuring the orderly startup of the entire system.

[0043] In some embodiments, sending a second power-down signal to the controller in response to the first power-down signal can be specifically implemented as follows: In response to the first power-down signal, a second power-down signal is sent to the controller so that the controller disconnects the second low-voltage power supply in response to the second power-down signal. A third power-down signal is sent to the battery cell after the second low-voltage power supply is disconnected.

[0044] In some embodiments, the step of the battery cell sending a second power-down signal to the controller in response to a first power-down signal can be further specifically implemented as sending a second power-down signal to the controller, so that the controller disconnects its output second low-voltage power supply in response to the second power-down signal, and sends a third power-down signal to the battery cell after disconnecting the second low-voltage power supply. In the embodiments of this application, the second low-voltage power supply may refer to the auxiliary low-voltage power supply provided by the controller to other components of the system (such as the interaction unit or control panel), for example, it may be a 12V or 24V DC power supply, used to maintain the operation of the display screen, buttons or other peripheral devices of the interaction unit.

[0045] Upon receiving the first power-down signal, the battery cell's internal control module sends a second power-down signal to the controller via a communication bus (such as a CAN bus). This signal carries a clear request, instructing the controller to initiate an orderly power-down operation. Upon receiving the second power-down signal, the controller first responds by disconnecting the second low-voltage power supply, thereby quickly powering down interactive units that rely on this power (such as the display and buttons on the throttle lever), preventing potential user errors or interference during the shutdown process. Simultaneously, the controller uses this buffer time to perform critical preparatory work, such as saving current operating data (e.g., mileage, motor load curves, alarm records) to prevent data loss. Only after completing the disconnection of the second low-voltage power supply and related preparations will the controller send a third power-down signal to the battery cell. This signal serves as an acknowledgment, indicating that the controller is ready and requests the battery cell to disconnect the high-voltage power supply.

[0046] Figure 2 A schematic diagram of the structure of one embodiment of the control system provided in this application is shown below. Figure 2 As shown, the control system may include: Battery unit 201 is used to receive a first power-down signal, and in response to the first power-down signal, send a second power-down signal to controller 202. If a third power-down signal is received from controller 202 based on the second power-down signal within a predetermined time, the high-voltage power supply output to power unit 203 is disconnected. If the third power-down signal is not received within the predetermined time, the high-voltage power supply and the first low-voltage power supply output to controller 202 are disconnected. The controller 202 is used to connect to the first low-voltage power supply output by the battery unit 201, receive the second power-off signal sent by the battery unit 201, and feed back the third power-off signal to the battery unit 201. Power unit 203 is used to connect to a high-voltage power supply.

[0047] The power unit 203 can be a power output device for a water propulsion device to drive the boat forward. For example, it can include components such as a motor drive board, a motor, and a propeller. The high-voltage power supply can be a power output with a higher voltage level to support the high power requirements of the power unit 203. For example, the voltage value can be 48V or higher.

[0048] The following combination Figure 2 The control system and specific application scenarios shown in this application illustrate the control method provided in the embodiments. This method can be applied to emergency power-down scenarios when an interactive system or ECU malfunctions in a water propulsion device (such as an electric outboard motor) while it is in operation, and it is also applicable to backup power-down operations under normal fault-free conditions.

[0049] In normal power-on mode, the battery unit outputs a first low-voltage power supply to power on the ECU. The ECU then outputs a second low-voltage power supply to power on the interactive system and requests the battery unit to close the high-voltage power switch via the interactive CAN bus, enabling the PCU to operate and the boat to enter the driving state. If the user initiates a normal power-off by pressing and holding the power-off button on the interactive system's control panel, the power-off button signal is transmitted to the ECU. The ECU executes an orderly power-off process, including saving operating data (such as mileage, motor load curves, and alarm records), disconnecting the second low-voltage power supply to power off the interactive system, and sending a request to the battery unit to disconnect the high-voltage power supply via the interactive CAN bus. Upon response, the battery unit disconnects the high-voltage power supply, and the system safely enters standby mode.

[0050] However, while the vehicle is running, the interactive system and ECU may malfunction, specifically in the following ways: First, the power off button on the control panel may be mechanically faulty, preventing the ECU from recognizing it regardless of whether the button is pressed; second, the electrical connection of the power off button signal on the control panel may fail, preventing the power off button signal from being transmitted to the ECU; third, the ECU itself may be damaged or experiencing a serious malfunction, rendering it unable to respond to any power off button signals as the control center. In these fault scenarios, the normal power-off path fails, and the user can initiate a backup power-off request by pressing and holding the power button on the battery unit.

[0051] Specifically, the battery unit first receives a first power-down signal. In this embodiment, receiving the first power-down signal is specifically implemented by receiving a first power-down signal generated by triggering the power button of the battery unit for more than a first preset time (e.g., 3 seconds). This long-press mechanism avoids accidental triggering and ensures that the user's intention is clear. The internal control module of the battery unit generates the first power-down signal after detecting that the power button has been pressed for more than the first preset time.

[0052] Upon receiving the first power-down signal, the battery unit immediately responds and sends a second power-down signal to the ECU. In this embodiment, this sending step is specifically implemented by sending the second power-down signal to the ECU via the interactive CAN bus. The ECU, in response to the second power-down signal, first disconnects the output of the second low-voltage power supply (powering down the interactive system), and then sends a third power-down signal to the battery unit after disconnecting the second low-voltage power supply. This second power-down signal is a specific power-down request message. If the ECU is operating normally, it will perform an orderly power-down operation upon receiving it, including saving current operating data, disconnecting the second low-voltage power supply to isolate interference from the interactive system, and sending the third power-down signal as confirmation after completing the preparation.

[0053] After sending the second power-down signal, the battery unit starts a timer to monitor whether it receives a third power-down signal from the ECU within a predetermined time (e.g., 500ms). If a third power-down signal is received within the predetermined time (corresponding to fault type one or two, and the ECU is normal), the battery unit only disconnects the high-voltage power supply to the PCU, the system safely enters standby mode, and the operating data is completely saved.

[0054] If the third power-down signal is not received within the predetermined time (corresponding to fault type three, ECU is damaged or seriously abnormal), the battery unit will simultaneously disconnect the high-voltage power supply to the PCU and the first low-voltage power supply to the ECU, thereby forcibly disconnecting all power and ensuring safety.

[0055] After a forced power outage, this application embodiment also provides a recovery mechanism. On one hand, automatic recovery can be achieved: the battery unit detects the duration of disconnection of the first low-voltage power supply. If the disconnection duration reaches a second preset duration (e.g., 10 to 20 seconds), it automatically re-outputs the first low-voltage power supply to the ECU, causing the ECU to reset and recover. This is suitable for scenarios where the ECU is unresponsive due to software faults such as program bugs. On the other hand, manual recovery can be achieved: the battery unit continues to monitor input after a forced power outage. If it receives a first power-on signal (e.g., the user presses the power button again), it responds to the first power-on signal by re-outputting the first low-voltage power supply to the ECU, allowing the ECU to reset and recover based on the first low-voltage power supply. Subsequently, the system can gradually restore the high-voltage power supply as needed.

[0056] Through the above embodiments, the control method provided in this application realizes intelligent hierarchical power-off: it prioritizes attempting to complete an orderly shutdown in coordination with the ECU to protect operating data to the greatest extent; it promptly forces a power-off to ensure safety when the ECU completely fails; and it provides automatic or manual reset and recovery functions to improve system robustness.

[0057] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the protection scope of the present invention.

[0063] In some embodiments, if no third power-down signal is received within a predetermined time, and the high-voltage power supply and the low-voltage power supply output to the controller are disconnected, the device may further include: The second receiving module is used to receive the first power-on signal; The fourth control module is used to respond to the first power-on signal by outputting a first low-voltage power supply to the controller so that the controller can perform a reset and recovery based on the first low-voltage power supply.
