Therefore, the technical features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0021] Figure 1 A structural diagram of an embodiment of a directional high-voltage charging wake-up system provided by the present invention is shown in FIG. Figure 1 As shown, the directional high-voltage charging wake-up system includes: Power battery management system 110, vehicle controller 120, vehicle charger 130, motor controller 140, gateway controller 150 and lithium battery controller 160; The power battery management system 110 is used to send a wake-up message to the vehicle controller 120, the on-board charger 130, the motor controller 140 and the gateway controller 150; The gateway controller 150 is used to forward the wake-up message to the lithium battery controller 160; The wake-up message is used to wake up the vehicle controller 120 , the on-board charger 130 , the motor controller 140 and the lithium battery controller 160 to perform high-voltage charging.

[0022] like Figure 1 As shown in the figure, the directional high-voltage charging wake-up system includes a control system and an execution system. The control system includes a vehicle control unit (VCU). The execution system includes: a power battery management system (BMS), an on-board charger (OBC), a motor control unit (MCU), a gateway controller (GW) and a lithium battery controller (LBM).

[0023] The power battery management system is responsible for monitoring and managing the status of the battery, including power, temperature, and voltage. In the directional high-voltage charging wake-up system, the power battery management system is awakened first to manage and coordinate other controllers.

[0024] The power battery management system wakes up the vehicle controller, on-board charger, motor controller and gateway controller by sending a wake-up message to the vehicle controller, on-board charger, motor controller and gateway controller.

[0025] Therefore, the gateway controller can forward the received network management signal (ie, the wake-up message) to the lithium battery controller to wake up the lithium battery controller.

[0026] After the vehicle controller, on-board charger, motor controller and lithium battery controller are awakened, they can work together to start the high-voltage charging function.

[0027] For example, after the vehicle controller is awakened, it can monitor the status of the entire vehicle and coordinate the work of each controller; after the on-board charger is awakened, it can execute the charging function; after the motor controller is awakened, it participates in the high-voltage power-on process to ensure that the motor maintains a proper working state during the charging process; after the lithium battery controller is awakened, it can monitor the status of the 12V lithium battery.

[0028] Compared with the prior art, the directional high-voltage charging wake-up system provided in the embodiment of the present invention sends a wake-up message to the vehicle controller, the on-board charger, the motor controller and the gateway controller through the power battery management system. The gateway controller forwards the wake-up message to the lithium battery controller, thereby waking up the vehicle controller, the on-board charger, the motor controller and the lithium battery controller according to the wake-up message to perform high-voltage charging. Through the directional wake-up mechanism, only the necessary controllers related to high-voltage charging are woken up, and the charging function can be realized without waking up all network segments, thereby greatly reducing the power consumption of the whole vehicle and greatly improving the charging efficiency.

[0029] In some embodiments of the present invention, the vehicle controller is used to send a high voltage instruction to the power battery management system; The power battery management system is used to close the relay based on the upper high voltage instruction; The motor controller is used to perform high voltage power-on after closing the relay; The on-board charger is used to perform high-voltage charging after the high-voltage power is turned on; The lithium battery controller is used to monitor the status of the lithium battery.

[0030] The vehicle controller is responsible for sending high-voltage instructions to the power battery management system and coordinating the entire charging process. In the directional high-voltage charging wake-up strategy, the vehicle controller ensures the coordinated work of each controller to improve charging efficiency and safety.

[0031] Based on the high-voltage instruction from the vehicle controller, the power battery management system closes the relay to ensure the connection between the battery and the charging system and prepare for high-voltage charging.

[0032] The motor controller executes the high-voltage power-on process after the relay is closed to ensure that the motor maintains proper working condition during the charging process and avoid equipment damage or safety hazards caused by excessive current.

[0033] The on-board charger starts to perform high-voltage charging tasks after the high-voltage power-on is completed. By converting the external power supply into electrical energy suitable for the battery, the on-board charger can ensure an efficient and safe battery charging process.

[0034] The lithium battery controller continuously monitors the status of the lithium battery during the entire charging process, including parameters such as power, temperature and voltage, to ensure that the battery operates within a safe range, prevent overcharging, overheating and other problems, and improve battery life and charging safety.

[0035] In some embodiments of the present invention, the power battery management system is specifically used for: The wake-up message is sent when the vehicle is in a dormant state and has no faults, and after the high-voltage charging gun is inserted into the vehicle charging port.

[0036] The BMS detects whether the vehicle is in a dormant state and confirms that the system has no faults to ensure that the vehicle is in a safe and stable initial state before waking up.

[0037] The BMS monitors the insertion status of the high-voltage charging gun in real time. When it detects that the charging gun is inserted, the BMS immediately triggers the subsequent wake-up process to ensure timely response to external charging requests.

[0038] After confirming that the vehicle is in sleep mode and has no faults and the high-voltage charging gun is inserted into the vehicle's charging port, the BMS sends a specific wake-up message to the vehicle controller, on-board charger, motor controller and gateway controller to notify the relevant controllers to prepare to enter charging mode and ensure that all systems work together.

[0039] The directional high-voltage charging wake-up system provided in the embodiment of the present invention, through the directional wake-up mechanism, only wakes up the necessary controllers, avoiding unnecessary power consumption and interference, not only improving the charging efficiency, but also enhancing the stability and safety of the system, ensuring that users get the best experience and safety during the charging process. By reducing unnecessary controller wake-ups, the power consumption of the entire vehicle is reduced, saving electricity and time costs for users.

[0040] In some embodiments of the present invention, the vehicle controller is specifically used for: Monitor vehicle status; When it is determined that the vehicle state meets the high-voltage condition, the high-voltage instruction is sent to the power battery management system.

[0041] The VCU is responsible for real-time monitoring of various status parameters of the vehicle, including battery power, temperature, voltage, and vehicle operation mode. By continuously monitoring these key data, the VCU can ensure that the vehicle is in a safe and stable initial state before charging.

[0042] The VCU determines whether the high-voltage conditions are met based on preset conditions and algorithms. The high-voltage conditions may include sufficient battery power, suitable battery temperature, no fault alarm, etc. When the high-voltage conditions are met, the VCU will proceed to the next step to ensure the safety and reliability of the charging process.

[0043] After confirming that the vehicle status meets the high-voltage conditions, the VCU sends a high-voltage command to the BMS. The high-voltage command is a signal to start the high-voltage charging process, notifying the BMS to prepare to execute the operation of closing the relay and prepare for high-voltage charging.

[0044] Figure 2 One of the method flow charts of an embodiment of the directional high-voltage charging wake-up method provided by the present invention is as follows Figure 2 As shown, the directional high-voltage charging wake-up method includes: S201, sending a wake-up message to the vehicle controller, the on-board charger, the motor controller and the gateway controller, and forwarding the wake-up message to the lithium battery controller through the gateway controller; S202: Wake up the vehicle controller, the onboard charger, the motor controller and the lithium battery controller based on the wake-up message to perform high-voltage charging.

[0045] The directional high-voltage charging wake-up method provided by the present invention may be executed by the directional high-voltage charging wake-up system described in any of the above embodiments.

[0046] In S201, the power battery management system sends a specific wake-up message to the vehicle controller, on-board charger, motor controller and gateway controller. The wake-up message is used to notify the relevant controllers to prepare to enter the charging mode to ensure that the systems work together. After receiving the wake-up message from the BMS, the gateway controller forwards it to the lithium battery controller.

[0047] In S202, after receiving the wake-up message, each controller is awakened in turn and enters the charging mode. The vehicle controller, onboard charger, motor controller and lithium battery controller will adjust their own states according to the received message and prepare to participate in the high-voltage charging process.

[0048] After completing the above wake-up process, the system starts to perform high-voltage charging tasks. The on-board charger is responsible for converting the external power supply into electrical energy suitable for the battery, and safely transmits the electrical energy to the battery by operating the closed relay. At the same time, the motor controller ensures that the motor maintains a proper working state during the charging process to avoid equipment damage or safety hazards caused by excessive current. The lithium battery controller continuously monitors the status of the battery, including parameters such as power, temperature and voltage, to ensure that the battery operates within a safe range.

[0049] Compared with the prior art, the directional high-voltage charging wake-up method provided in the embodiment of the present invention, through a directional wake-up mechanism, only wakes up the necessary controllers related to high-voltage charging, and does not require all network segments to be woken up to realize the charging function, thereby greatly reducing the power consumption of the entire vehicle and greatly improving the charging efficiency.

[0050] In some embodiments of the present invention, waking up the vehicle controller, the onboard charger, the motor controller, and the lithium battery controller based on the wake-up message to perform high-voltage charging includes: Sending a high voltage command to the power battery management system through the vehicle controller; Closing a relay via the power battery management system; Executing high voltage power-up by the motor controller; Performing high-voltage charging by means of the on-board charger; The status of the lithium battery is monitored by the lithium battery controller.

[0051] After receiving the wake-up message, the vehicle controller first confirms whether the vehicle status meets the high-voltage conditions. If so, it will send a high-voltage instruction to the power battery management system. The high-voltage instruction is a signal to start the high-voltage charging process, notifying the power battery management system to prepare to execute the closing relay operation and prepare for high-voltage charging.

[0052] After receiving the high-voltage command from the vehicle controller, the power battery management system will execute the operation of closing the relay to ensure that the connection between the battery and the external power supply is safe and stable.

[0053] After the relay is closed, the motor controller performs high-voltage power-on operations to ensure that the motor maintains proper working conditions during the charging process and avoids equipment damage or safety hazards caused by excessive current. The MCU is responsible for coordinating various parameters of the motor to adapt it to the needs of high-voltage charging.

[0054] After receiving the wake-up message and completing the preparation work, the on-board charger starts to perform the high-voltage charging task, converting the external power supply into electric energy suitable for the battery, and safely transmitting the electric energy to the battery through the operation of the closed relay. The OBC is responsible for monitoring the entire charging process to ensure charging efficiency and safety.

[0055] The lithium battery controller continuously monitors the battery status during the entire high-voltage charging process, including parameters such as power, temperature and voltage. It ensures that the battery operates within a safe range to prevent overcharging, overheating and other problems. If any abnormality is detected, LBM will take corresponding measures, such as adjusting the charging rate or stopping charging, to ensure the safety and life of the battery.

[0056] The directional high-voltage charging wake-up method provided in the embodiment of the present invention, through the directional wake-up mechanism, only wakes up the necessary controllers, avoids unnecessary power consumption and interference, not only improves the charging efficiency, but also enhances the stability and safety of the system, ensuring that users get the best experience and safety during the charging process. By reducing unnecessary controller wake-ups, the power consumption of the entire vehicle is reduced, saving electricity and time costs for users.

[0057] In some embodiments of the present invention, sending a wake-up message to the vehicle controller, the on-board charger, the motor controller, and the gateway controller includes: When the vehicle is in sleep mode and has no faults, and the high-voltage charging gun is inserted into the vehicle's charging port, a wake-up message is sent to the vehicle controller, on-board charger, motor controller and gateway controller through the power battery management system.

[0058] When the vehicle is in sleep mode, all controllers and system components are in low power mode to save power. At this time, the vehicle should ensure that there is no fault so that subsequent operations can be carried out safely.

[0059] When the power battery management system detects that the user plugs the high-voltage charging gun into the vehicle charging port, the power battery management system will be awakened. The power battery management system is responsible for monitoring the status of the battery, including parameters such as power, temperature and voltage, and ensuring that the battery operates within a safe range.

[0060] When the power battery management system confirms that the vehicle is in sleep mode and has no faults, it will send specific wake-up messages to the vehicle controller, onboard charger, motor controller and gateway controller. These messages are used to notify the relevant controllers to prepare to enter charging mode to ensure that the systems work together.

[0061] The directional high-voltage charging wake-up method provided in the embodiment of the present invention reduces interference and conflict between systems through a directional wake-up mechanism, and enhances the stability and reliability of the system. By accurately controlling the wake-up and sleep states of each controller, it ensures that each component is activated at the appropriate time, avoiding system failure or performance degradation caused by misoperation.
