[0002] With the continuous development of electric vehicle technology, the sentry function has been widely adopted as an important safety monitoring tool in electric vehicles. After the vehicle is parked and locked, the sentry function monitors the vehicle's surroundings through visual sensors such as cameras. When an abnormality or threat of tampering is detected, it promptly records the incident and issues an alarm to notify the owner. However, traditional power supply solutions for the visual sentry function have many shortcomings. A common solution is to use a low-voltage battery, but low-voltage batteries have limited capacity and cannot support round-the-clock monitoring needs. Another solution is to use a power battery. Although the power battery has sufficient power, activating the sentry function will wake up the high-voltage system, resulting in high energy consumption and reduced energy efficiency.

[0049] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0050] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0051] The main solution of the embodiment of the present application is: obtaining the operating status of the visual sentinel, the charge state, the health state and the temperature of the battery; obtaining the battery pack control strategy based on the operating status, the charge state, the health state and the temperature; switching the power battery according to the battery pack control strategy so that the power battery supplies power to the visual sentinel.

[0052] With the continuous development of electric vehicle technology, the sentry function has been widely adopted as an important safety monitoring tool in electric vehicles. After the vehicle is parked and locked, the sentry function monitors the vehicle's surroundings through visual sensors such as cameras. When an abnormality or threat of tampering is detected, it promptly records the incident and issues an alarm to notify the owner. However, traditional power supply solutions for the visual sentry function have many shortcomings. A common solution is to use a low-voltage battery, but low-voltage batteries have limited capacity and cannot support round-the-clock monitoring needs. Another solution is to use a power battery. Although the power battery has sufficient power, activating the sentry function will wake up the high-voltage system, resulting in high energy consumption and reduced energy efficiency.

[0053] This application monitors the status of the power battery in real time and intelligently controls the power supply strategy based on the status information, thereby minimizing energy consumption and improving battery energy utilization while meeting the sentinel function requirements.

[0054] It should be noted that the execution entity of this embodiment can be a power supply system based on visual sentinels, a computing service device with data processing, network communication, and program execution functions, or an electronic device capable of implementing the above-mentioned power supply functions based on visual sentinels, etc., and this embodiment does not specifically limit this. The following uses a power supply system based on visual sentinels as an example to illustrate this embodiment and the following embodiments.

[0055] Based on this, the embodiment of the present application provides a power supply method based on visual sentinel, the method is applied to a power supply system based on visual sentinel, the system includes: a battery pack, a plurality of power batteries are provided in the battery pack, each of the power batteries is connected to the visual sentinel, Figure 1 , Figure 1 This is a flow chart of the first embodiment of the power supply method based on visual sentinel of this application.

[0056] In this embodiment, the power supply method based on visual sentinel includes steps S10 to S30:

[0057] Step S10: Obtain the operating status of the visual sentinel, the battery state of charge, health status and temperature.

[0058] It should be noted that in this step, the vehicle will obtain abnormal vibrations of the vehicle body and real-time information around the vehicle through the monitoring system and BCM (Body Control Module) to confirm the operating status of the visual sentinel. At the same time, the SOC (State of Charge), SOH (State of Health) and temperature of the power battery and low-voltage battery will be monitored in real time through the BMS (Battery Management System).

[0059] In addition, it should be noted that the operating status of the visual sentinel refers to the operating status of the visual sentinel system at this time, including the activated state and the closed state; the state of charge refers to the ratio of the remaining battery power to the fully charged capacity, which is used to reflect the remaining battery power; the health status is used to evaluate the degree of battery attenuation, including changes in parameters such as battery capacity and internal resistance; the temperature is used to monitor the thermal state of the battery to prevent overheating from causing battery damage or safety accidents.

[0060] In a feasible implementation, obtaining the operating status of the visual sentinel specifically includes:

[0061] Step A10: Acquire the vehicle's posture information, image information around the vehicle, and radar information.

[0062] It should be noted that in this step, the system will obtain the vehicle's posture information through the inertial measurement unit installed on the vehicle. This posture information includes but is not limited to the vehicle's acceleration, angular velocity, tilt angle, etc. This information can reflect whether the vehicle is currently in a stable state and whether it is likely to be interfered with or damaged by external forces. Then, a panoramic monitoring system (camera) is used to capture image information around the vehicle. These cameras are placed in key positions of the vehicle and can monitor the environment around the vehicle in all directions, including areas around the vehicle, on the roof, etc. The image information captured by the camera will be used to analyze whether there are suspicious objects or abnormal situations around the vehicle. At the same time, the vehicle can obtain radar information through the installed radar system. The radar system can emit and receive electromagnetic waves, and determine parameters such as the distance, speed and direction of surrounding objects by measuring the reflection time and intensity of the electromagnetic waves. It can be understood that this information can determine whether there are potential safety hazards around the vehicle.

[0063] Step A20: Obtain the operating status of the visual sentry according to the image information, radar information and posture information.

[0064] It should be noted that in this step, the acquired image information, radar information, and posture information are input into the Sentinel Master Control Module for processing. The Sentinel Master Control Module is a central controller that integrates multiple sensor data processing algorithms. It integrates and analyzes the input information to obtain a comprehensive status of the vehicle and its surroundings. The Sentinel Master Control Module uses pre-set algorithms to analyze and judge the input information. These algorithms include, but are not limited to, image processing algorithms, radar signal processing algorithms, and posture recognition algorithms. By applying these algorithms, the Sentinel Master Control Module can identify whether there are suspicious objects or abnormal conditions around the vehicle and, based on this, determine whether the Visual Sentinel system should be activated or continued. Finally, based on the judgment result, the Sentinel Master Control Module outputs the corresponding instructions to control the operation of the Visual Sentinel system. If the judgment result indicates that the Visual Sentinel system should be activated, the Sentinel Master Control Module sends a command to the relevant controller to start recording video and audio information of the surrounding environment. If the judgment result indicates that the Visual Sentinel system should not be continued, the Sentinel Master Control Module sends a command to deactivate the Visual Sentinel function.

[0065] It can be understood that the purpose of this step is to comprehensively analyze and judge the collected information, thereby determining the operating status of the visual sentry and controlling it as needed. This ensures that the visual sentry is activated when needed and shut down when not needed, thereby ensuring vehicle safety while avoiding unnecessary energy consumption.

[0066] Step S20: Obtaining a battery pack control strategy according to the operating state, the state of charge, the health state, and the temperature.

[0067] It should be noted that during this step, the BMS comprehensively assesses the battery pack's status and formulates appropriate control strategies. For example, if a battery's SOC or SOH falls below a set threshold, the BMS will determine that the battery is low and initiate a corresponding low-battery protection strategy. If the battery temperature rises abnormally, the BMS will initiate a battery protection strategy, cutting off battery output to prevent damage or safety incidents. Furthermore, based on the operating status of the Visual Sentinel, the BMS will determine whether to switch battery packs for power. For example, if the current power battery's charge level does not meet the required supply requirements, the BMS will instruct the battery pack to switch to the next power battery to ensure continuous operation of the Visual Sentinel. For example, when the vehicle is in park and locked with Sentinel mode engaged, if the BCM detects abnormal body vibration or an anti-theft trigger, it will send a signal to the Sentinel main control module. The Sentinel main control module will then activate its cameras and radar for monitoring and upload the relevant information to the IVI. At this point, the BMS will formulate battery pack control strategies based on the power battery status and the power requirements of the Visual Sentinel, such as switching battery modules and adjusting the supply voltage.

[0068] In addition, it should be noted that the battery pack control strategy is pre-formulated based on the battery status and power demand, and is intended to ensure safe and efficient use of the battery.

[0069] Step S30: switching the power battery according to the battery pack control strategy so that the power battery supplies power to the visual sentry.

[0070] It should be noted that if Figure 2 As shown in the figure, the power supply system based on the visual sentinel includes: power battery, 12V battery, low voltage BMS, high voltage BMS, VCU, DC-DC, low voltage 12V system and visual sentinel system. Figure 3 As shown, in this step, according to the pre-established battery pack control strategy (such as when switching the power supply strategy), the BMS will send an instruction to the battery control unit (BCU), instructing it to switch to the designated battery module to power the visual sentinel. The BCU (Battery Control Unit) and the BMU (Battery Management Unit) will receive the instruction and perform the switching operation, while monitoring the status of the newly switched battery module to ensure its normal operation. Specifically, the BMS will select a power battery that meets the power supply conditions based on the power level and health status of the power battery in the current battery pack to output a 12V voltage (the actual output voltage is 13-14V) to the DC-DC converter. The DC-DC converter then converts this 12V voltage into the voltage required by the on-board low-voltage 12V system, thereby powering the visual sentinel function. It can be understood that the role of the VCU is to provide various status information of the entire vehicle and output high or low voltage to the BMS.

[0071] Furthermore, it should be noted that the battery switching process is intelligently controlled by the battery management system, ensuring the continuity and stability of power supply. Furthermore, by monitoring the battery status in real time and dynamically adjusting the power supply strategy, energy utilization and battery life can be maximized.

[0072] In a feasible implementation manner, the step S30 specifically includes:

[0073] Step S301: When the battery pack control strategy is a switching power supply strategy, the current power battery in the battery pack is switched to a target power battery according to the switching power supply strategy, so that the target power battery supplies power to the visual sentinel, and the remaining power of the target power battery is greater than the remaining power of the current battery.

[0074] Specifically, when the battery pack control strategy is set to switch power supply, the system first checks the remaining charge of each power battery in the battery pack. It then makes a determination based on the remaining charge of each power battery and a preset remaining charge threshold. If the remaining charge of the current power battery is less than the preset remaining charge threshold, the system will select a power battery with a remaining charge greater than the preset remaining charge threshold as the target power battery based on the remaining charge. The target power battery with the highest remaining charge will then be used to power the current visual sentinel.

[0075] In a feasible implementation manner, after step S30, steps S40 to S50 are further included:

[0076] Step S40: Obtain the battery pack power of the power battery.

[0077] It should be noted that in this step, obtaining the battery pack power of the power battery is achieved through the BMS. The BMS collects and processes key parameters such as the current, voltage, and temperature of the power battery module in real time to calculate the total power of the battery pack. It can be understood that the purpose of this step is to monitor the power state of the power battery in real time so that the power battery module can be switched or the power supply of the Visual Sentinel can be cut off when necessary.

[0078] In addition, it should be noted that the battery pack power refers to the total power of all power batteries, which reflects the total remaining energy of the power batteries.

[0079] Step S50: When the power level of the battery pack is less than a preset power supply threshold, the power supply of the visual sentinel is cut off.

[0080] It should be noted that in this step, the preset power supply threshold is set to 15% of the total power of the power battery. When the BMS detects that the battery pack power is lower than this threshold, it will immediately cut off the power supply to the visual sentinel function to prevent the power battery from having insufficient remaining power. For example, after the visual sentinel function has been running for a period of time, the BMS detects that the battery pack power has dropped below the preset power supply threshold. At this time, the BMS will send an instruction to the sentinel main controller, requiring it to turn off the visual sentinel function and cut off the power supply to the relevant systems. At the same time, the BMS will also send an early warning message to the user through the vehicle's cloud platform, prompting the user that the power battery is low and needs to be processed as soon as possible. It can be understood that the purpose of this step is to ensure that the remaining power of the power battery is sufficient to support the operation of the vehicle, and to avoid the vehicle being unable to start or drive due to excessive power consumption by the visual sentinel function.

[0081] This embodiment provides a power supply method based on a visual sentinel. The method of this embodiment includes: obtaining the operating status of the visual sentinel, the state of charge, health status, and temperature of the battery; obtaining a battery pack control strategy based on the operating status, the state of charge, the health status, and the temperature; and switching the power battery according to the battery pack control strategy so that the power battery supplies power to the visual sentinel. In summary, this embodiment achieves the goal of meeting the sentinel's functional requirements while minimizing energy consumption and improving battery energy utilization by monitoring the status of the power battery in real time and intelligently controlling the power supply strategy based on the status information.

[0082] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above embodiment 1 can be referred to the above introduction and will not be described in detail later. Figure 4 , Figure 4 This is a flow chart of the second embodiment of the power supply method based on visual sentinel of this application, wherein step S20 specifically includes:

[0083] Step S201: when the operating state is an active state, obtaining a functional state of the battery according to the state of charge, the state of health, and the temperature.

[0084] It should be noted that in this step, when the operating status of the battery pack is determined to be activated, it means that the battery pack is in working condition, and the system will comprehensively consider the battery's state of charge (SOC), state of health (SOH) and temperature information to determine the battery's state of function (SOF). Specifically, the system will evaluate the functional status of the power battery and the storage battery in the current state according to the preset evaluation range (including the preset charge threshold, the preset health threshold and the preset temperature threshold). For example, when the visual sentinel function is turned on, if the SOC of the power battery is lower than 20%, the SOH is lower than 80% or the temperature exceeds 80°C, the functional state (SOF) of the battery pack will be determined to be 0 (that is, the conditions are not met).

[0085] It's also important to note that the state of function (SOF) is a comprehensive indicator that reflects the battery's ability to meet the functional requirements of the battery pack control strategy in its current state. In this step, SOF can be considered a function of SOC, SOH, and temperature: SOF = f(SOC, SOH, temperature). This functional relationship allows for a more accurate assessment of the battery pack's functional state and the development of appropriate control strategies.

[0086] In a feasible implementation manner, the step S201 specifically includes:

[0087] Step B10: when the operating state is the active state, obtaining a charge flag according to the charge state and a preset charge threshold.

[0088] It should be noted that when the visual sentinel function of an electric vehicle is activated, the BMS will obtain the current state of charge of the power battery and the storage battery, that is, the percentage of the remaining battery power to the total capacity. Subsequently, the BMS will compare this state of charge with the preset charge threshold. If the state of charge is greater than or equal to the preset charge threshold (for example, preset to 20%), the BMS will set the charge flag to "1", indicating that the battery is now sufficiently charged to support the normal operation of the visual sentinel function. If the state of charge is lower than the preset charge threshold, the BMS will set the charge flag to "0", indicating that the battery is insufficient and it is necessary to switch the power battery in the battery pack to maintain the operation of the visual sentinel function.

[0089] It's important to note that the state of charge (SOC) refers to both the power battery and the storage battery. The preset charge threshold is determined based on factors such as the type of electric vehicle, the performance of the power battery and storage battery, and the power consumption of the visual sentinel function. This ensures the proper functioning of the visual sentinel function while preventing damage to the power battery or storage battery due to over-discharge.

[0090] Step B20: Obtain a health flag according to the health status and a preset health threshold.

[0091] It should be noted that in this step, the BMS will also monitor the health status of the power battery and the storage battery in real time, that is, the ability of the battery to maintain its original performance during use. This usually includes indicators such as the cycle life, internal resistance, and capacity attenuation of the battery. The BMS will compare this health status with the preset health threshold. If the health status is higher than or equal to the preset threshold (for example, the preset threshold is 80%), the BMS will set the health flag to "1", indicating that the battery is in good working condition. If the health status is lower than the preset threshold, the BMS will set the health flag to "0", indicating that the battery is at risk of performance degradation or failure and requires further inspection or repair.

[0092] It should also be noted that health status refers to both the power battery and the storage battery. The setting of preset health thresholds also needs to consider factors such as the type of electric vehicle, the performance of the power battery and storage battery, and the power consumption of the visual sentinel function. The purpose is to promptly detect potential power battery issues and ensure the safety and reliability of electric vehicles.

[0093] Step B30: Obtaining a temperature flag according to the temperature state and a preset temperature threshold.

[0094] It should be noted that in this step, the BMS will also monitor the temperature status of the power battery and the storage battery in real time. Since the battery generates heat during operation, if the temperature is too high or too low, it may affect its performance and safety. Therefore, the BMS will compare the current temperature of the battery with the preset temperature threshold. If the temperature is within the preset appropriate range (for example, preset between 0°C and 75°C), the BMS will set the temperature flag to "1". If the temperature exceeds this range, the BMS will set the temperature flag to "0" and take appropriate measures (such as turning off some functions of the visual sentinel, disconnecting the power supply, etc.) to protect the battery from damage.

[0095] It should also be noted that temperature conditions refer to both the power battery and the storage battery. The setting of the preset temperature thresholds must take into account factors such as the battery's material properties, the operating environment, and the power consumption of the visual sentinel function. The goal is to ensure that the battery operates within an appropriate temperature range, thereby extending its service life and improving the overall performance of the electric vehicle.

[0096] Step B40: Obtaining a functional status according to the charge flag, the health flag, and the temperature flag.

[0097] It should be noted that in this step, the BMS will make a comprehensive judgment based on the obtained charge flag, health flag, and temperature flag. If all flags are "1" (ie normal), the BMS will set the functional status to "1", indicating that the functional status of the battery is normal at this time, and the BMS will allow the visual sentinel function to continue to run. If any flag is "0" (ie abnormal), the BMS will set the functional status to "0", indicating that corresponding measures will be taken (such as switching battery packs, turning off some functions, or completely turning off the visual sentinel function, etc.) to protect the battery and avoid potential safety risks.

[0098] Additionally, it should be noted that the functional status includes the functional status of the power battery and the functional status of the storage battery.

[0099] Step S202: Obtaining a battery pack control strategy according to the functional status.

[0100] It should be noted that in this step, the system determines the control strategy to be adopted based on the corresponding functional state. Specifically, the control strategy is transmitted to the relevant controller via the communication bus for execution. Based on the received instructions, the controller adjusts the battery pack's power supply mode to switch the battery packs. Furthermore, it should be noted that the functional state refers to the functional state of the power battery and the functional state of the storage battery.

[0101] In this embodiment, by determining the battery pack control strategy to be adopted based on the functional status of the power battery and the functional status of the storage battery, refined management of the battery pack can be achieved, ensuring that the battery pack operates in the most power-saving state while avoiding damage to the battery pack caused by adverse factors such as overcharging, over-discharging, and overheating.

[0102] Based on the first and second embodiments of the present application, in the third embodiment of the present application, the same or similar contents as those in the first and second embodiments can be referred to above and will not be described in detail. Figure 5 , Figure 5 This is a flow chart of the third embodiment of the power supply method based on visual sentinel of this application, wherein step S202 specifically includes:

[0103] Step C10: When the power battery functional state and the storage battery functional state are both in the first state, determining that the battery pack control strategy is a power saving power supply strategy.

[0104] It should be noted that in this step, when both the power battery and storage battery functional states are in the first state, the system determines to adopt a power-saving power supply strategy. This strategy primarily optimizes the control logic of the power management system to minimize energy consumption while meeting the requirements of the visual sentinel function. Specifically, the BMS monitors the power battery and storage battery charge and health status in real time and dynamically adjusts the DC-DC conversion efficiency based on this information, ensuring stable power output while minimizing energy consumption.

[0105] Additionally, it should be noted that the first state of the functional state represents a state that can meet the requirements for the operation of the visual sentinel function at present or in the future.

[0106] Step C20: When the power battery functional state is the first state and the storage battery functional state is the second state, determining that the battery pack control strategy is a supplementary power supply strategy.

[0107] It should be noted that in this step, when the power battery is in the first state and the storage battery is in the second state, the system determines to adopt the supplementary power supply strategy. This strategy mainly utilizes the surplus power of the power battery to supplement the battery through the DC-DC converter to ensure that the battery can provide the necessary power supply when the visual sentinel function is turned on. For example, when the owner turns on the sentry mode while the vehicle is parked, and the battery is exhausted for some reason (such as the vehicle has not been used for a long time, causing the battery to discharge naturally), the BMS will detect this state and start the supplementary power supply strategy. At this time, the power battery will serve as a power source to charge the battery through the DC-DC converter until the battery power returns to a preset level (such as the minimum power threshold that can support the operation of the visual sentinel function for a period of time).

[0108] It is understandable that the second state refers to a state that cannot meet the requirements for the operation of the visual sentinel function at present or in the future.

[0109] Step C30: When the power battery functional state is the second state and the storage battery functional state is the first state, determining that the battery pack control strategy is a switching power supply strategy.

[0110] It should be noted that when the functional states of the power battery and the storage battery are both in the second state, when the power battery is in the second state and the storage battery is in the first state, the system determines to adopt a switching power supply strategy. This strategy mainly switches the power source of the visual sentinel function from the current power battery that is out of power in the battery pack to a power battery with sufficient power by switching the power supply, so as to ensure that the visual sentinel function can still operate normally when the current power battery is insufficient. It is understandable that when the power battery cannot meet the power supply requirements of the visual sentinel function, the problem of visual sentinel function interruption caused by the exhaustion of the current power battery can be avoided by switching the battery pack to another power battery for power supply, thereby improving the reliability and stability of the system.

[0111] Step C40: When the power battery functional state and the storage battery functional state are both in the second state, determining that the battery pack control strategy is a power replenishment switching strategy.

[0112] It should be noted that when both the power battery and the storage battery are in the second state, the system determines that the battery pack control strategy is the recharge switching strategy. Specifically, the BMS continuously monitors the status of the power battery and the storage battery. If it detects that neither can meet the power supply requirements of the Visual Sentinel function, the system switches from the current power battery to the other power battery. The switched power battery then recharges the storage battery, while the power battery also provides power for the Visual Sentinel function.

[0113] In this embodiment, by real-time monitoring of the battery status and dynamically adjusting the control strategy of the battery pack, energy utilization is maximized, the stability and reliability of the system are enhanced, and the continuous and effective operation of the sentinel function is ensured.
