Description

Technical Field

[0001] The present application relates to the technical field of battery power supply, and in particular to a power supply method, device, equipment and storage medium based on visual sentinel. Background Art

[0002] With the continuous development of electric vehicle technology, the sentinel function has been widely used in electric vehicles as an important means of safety monitoring. After the vehicle is parked and locked, the sentinel function can monitor the surrounding environment of the vehicle through visual sensors such as cameras. When an abnormal situation or danger of damage is detected, the video of the incident is recorded in time and an alarm is issued to notify the owner. However, the traditional power supply scheme for the visual sentinel function has many shortcomings. A common solution is to use a low-voltage battery for power supply, but the power of the low-voltage battery is limited and cannot support all-weather monitoring needs. Another solution is to use a power battery for power supply. Although the power battery has sufficient power, turning on the sentinel function will wake up the high-voltage system, resulting in high energy consumption and reduced energy utilization.

[0049] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used 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 status, the health status and the temperature of the battery; obtaining the battery pack control strategy according to the operating status, the charge status, the health status and the temperature; switching the power battery according to the battery pack control strategy so that the power battery powers the visual sentinel.

[0052] With the continuous development of electric vehicle technology, the sentinel function has been widely used in electric vehicles as an important means of safety monitoring. After the vehicle is parked and locked, the sentinel function can monitor the surrounding environment of the vehicle through visual sensors such as cameras. When an abnormal situation or danger of damage is detected, the video of the incident is recorded in time and an alarm is issued to notify the owner. However, the traditional power supply scheme for the visual sentinel function has many shortcomings. A common solution is to use a low-voltage battery for power supply, but the power of the low-voltage battery is limited and cannot support all-weather monitoring needs. Another solution is to use a power battery for power supply. Although the power battery has sufficient power, turning on the sentinel function will wake up the high-voltage system, resulting in high energy consumption and reduced energy utilization.

[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 subject of this embodiment can be a power supply system based on visual sentinels, or a computing service device with data processing, network communication and program running functions, or an electronic device that can realize the above-mentioned power supply function based on visual sentinels, etc., and this embodiment does not specifically limit this. The following takes the 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 comprises: 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, and the power battery 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 the present 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 are 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 manner, 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. The posture information includes but is not limited to the acceleration, angular velocity, tilt angle, etc. of the vehicle. This information can reflect whether the vehicle is currently in a stable state and whether it is likely to be disturbed or damaged by external forces. Then, the panoramic monitoring system (camera) is used to capture image information around the vehicle. These cameras are arranged at key positions of the vehicle and can monitor the environment around the vehicle in all directions, including areas around the vehicle, the roof, etc. The image information captured by the camera will be used to analyze whether there are suspicious objects or abnormal conditions 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 judge the distance, speed, direction and other parameters 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 sentinel 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 will be input into the sentinel main control module for processing. The sentinel main control module is a central controller that integrates multiple sensor data processing algorithms. It can fuse and analyze the input information to obtain the comprehensive state of the vehicle and its surrounding environment. The sentinel main control module uses a preset algorithm to parse and judge the input information. These algorithms include but are not limited to image processing algorithms, radar signal processing algorithms, and posture recognition algorithms. Through the application of these algorithms, the sentinel main control module can identify whether there are suspicious objects or abnormal conditions around the vehicle, and judge whether the visual sentinel needs to be started or continue to run. Finally, according to the judgment result, the sentinel main control module will output corresponding instructions to control the running state of the visual sentinel. If the judgment result is that the visual sentinel needs to be started, the sentinel main control module will send instructions to the relevant controller to start and start recording the video and audio information of the surrounding environment; if the judgment result is that the visual sentinel does not need to continue to run, the sentinel main control module will send instructions to turn off the visual sentinel function.

[0065] It is understandable that the purpose of this step is to comprehensively analyze and judge the collected information, so as to obtain the operating status of the visual sentinel and control it as needed. This can ensure that the visual sentinel is activated in time when needed and shut down in time when not needed, thereby avoiding unnecessary energy consumption while ensuring vehicle safety.

[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 in this step, the BMS will comprehensively judge the state of the battery pack and formulate corresponding control strategies. For example, when the SOC or SOH of the battery is lower than the set threshold, the BMS will judge that the battery is in a low-power state at this time and start the corresponding low-power protection strategy; when the battery temperature rises abnormally, the BMS will start the battery protection strategy and cut off the battery output to prevent battery damage or safety accidents. At the same time, according to the operating status of the visual sentinel, the BMS will determine whether it is necessary to switch the battery pack to supply power. For example, when the power of the current power battery does not meet the power supply conditions, the BMS will instruct the battery pack to switch to the next power battery to continue to supply power to ensure the continuous operation of the visual sentinel. For example, when the vehicle is in the parking lock state and the sentinel mode is running, if the BCM detects abnormal vibration of the vehicle body or anti-theft triggering and other events, it will send a signal to the sentinel main control module. The sentinel main control module will start the camera and radar for monitoring and upload the relevant information to the IVI. At this time, the BMS will formulate a battery pack control strategy based on the state of the power battery and the power demand of the visual sentinel, such as switching battery modules and adjusting the power 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, aiming to ensure the safe and efficient use of the battery.

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

[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 storage 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 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 to output a 12V voltage (the actual output voltage is 13-14V) to the DC-DC converter based on the power and health status of the power battery in the current battery pack. 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] In addition, it should be noted that the process of switching power batteries is achieved through the intelligent control of the battery management system, which aims to ensure the continuity and stability of power supply. At the same time, by real-time monitoring of the battery status and dynamic adjustment of 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] It should be noted that, specifically, when the battery pack control strategy is determined to be the switching power supply strategy, the system will first detect the remaining power of each power battery in the battery pack. Then, a judgment is made based on the remaining power of the power battery and the preset remaining power threshold. When the remaining power of the current power battery is less than the preset remaining power threshold, the system will select the power battery with a remaining power greater than the preset remaining power threshold as the target power battery based on the remaining power, and select the target power battery with the largest remaining power as the power battery for powering 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, the battery pack power of the power battery is obtained through the BMS. The BMS will collect and process key parameters such as the current, voltage and temperature of the power battery module in real time, and then calculate the total power of the battery pack. It can be understood that the role of this step is to monitor the power status of the power battery in real time so as to switch the power battery module or cut off the power supply of the visual sentinel 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 running low on 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 power to related 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, and the method of this embodiment includes: obtaining the operating status of the visual sentinel, the charge state, the health state, and the temperature of the battery; obtaining a battery pack control strategy according to 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. In summary, this embodiment monitors the status of the power battery in real time and intelligently controls the power supply strategy based on the status information, thereby achieving the goal of minimizing energy consumption and improving the energy utilization of the battery while meeting the functional requirements of the sentinel.

[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-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 4 , Figure 4 This is a flow chart of the second embodiment of the power supply method based on visual sentinel of the present application, wherein step S20 specifically includes:

[0083] Step S201: when the operating state is an activated 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 state 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 state 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 judged as 0 (that is, the conditions are not met).

[0085] In addition, it should be noted that the functional state (SOF) is a comprehensive indicator that reflects the ability of the battery to meet the functional requirements of the battery pack control strategy in the current state. In this step, SOF can be regarded as a function of SOC, SOH and temperature, that is, SOF = f (SOC, SOH, temperature). Through this functional relationship, the functional state of the battery pack can be more accurately evaluated and the corresponding control strategy can be formulated.

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

[0087] Step B10: when the operating state is an activated state, a charge flag is obtained 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 in 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] In addition, it should be noted that the state of charge refers to the state of charge of the power battery and the state of charge of the storage battery; and the preset charge threshold is set based on the type of electric vehicle, the performance of the power battery and the storage battery, and the power consumption of the visual sentinel function. The purpose is to ensure the normal operation of the visual sentinel function while preventing the power battery or the storage battery from being damaged due to excessive 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 decay 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, preset to 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] In addition, it should be noted that the health status refers to the health status of the power battery and the health status of the storage battery; the setting of the preset health threshold also needs to consider factors such as the type of electric vehicle, the performance of the power battery and the storage battery, and the power consumption of the visual sentinel function. The purpose is to timely discover potential problems with the power battery and ensure the safety and reliability of the electric vehicle.

[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] In addition, it should be noted that the temperature state refers to the temperature state of the power battery and the temperature state of the storage battery; the setting of the preset temperature threshold needs to take into account factors such as the material properties of the battery, the working environment, and the power consumption of the visual sentinel function. The purpose is to ensure that the battery operates within a suitable temperature range to extend its service life and improve 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, shutting down some functions, or completely shutting down the visual sentinel function, etc.) to protect the battery and avoid potential safety risks.

[0098] In addition, 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 will determine the control strategy to be adopted according to the corresponding functional state. Specifically, the control strategy is sent to the relevant controller for execution via the communication bus. The controller adjusts the power supply mode of the battery pack to switch the battery pack according to the received instructions. In addition, 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 according to the functional status of the power battery and the functional status of the storage battery, refined management of the battery pack can be achieved to ensure 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 the above description, and will not be described in detail later. Figure 5 , Figure 5 This is a flow chart of the third embodiment of the power supply method based on visual sentinel of the present application, wherein step S202 specifically includes:

[0103] Step C10: When the power battery function state and the storage battery function 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 the power battery function state and the storage battery function state are both in the first state, the system determines to adopt a power-saving power supply strategy. This strategy is mainly to optimize the control logic of the power management system to reduce energy consumption as much as possible while meeting the requirements of the visual sentinel function. Specifically, the BMS will monitor the power and health status of the power battery and storage battery in real time, and dynamically adjust the DC-DC conversion efficiency based on this information to ensure that energy consumption is minimized while providing stable power output.

[0105] In addition, 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 function state is in the first state and the storage battery function state is in 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 a supplementary power supply strategy. This strategy mainly utilizes the surplus power of the power battery to supplement the battery through a 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 battery is naturally discharged due to long-term non-use of the vehicle), the BMS will detect this state and start the supplementary power supply strategy. At this time, the power battery will be used as a power source to charge the battery through a 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 in the second state and the storage battery functional state is in 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 short 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 interruption of the visual sentinel function 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 function state and the storage battery function 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 the functional status of the power battery and the storage battery are both in the second state, the system will determine that the battery pack control strategy is a power replenishment switching strategy. Specifically, the BMS will continuously monitor the status of the power battery and the storage battery. When it is detected that neither of them can meet the power supply requirements of the visual sentinel function, the system will switch the current power battery to another power battery, and then use the switched power battery to replenish the battery, and the power battery will power 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, maximum energy utilization is achieved, the stability and reliability of the system are enhanced, and the continuous and effective operation of the sentinel function is ensured.
