Description

Technical Field

[0001] The present invention relates to the technical field of power failure prevention, and in particular to a lead-acid battery power failure prevention monitoring and control method and system. Background Art

[0002] In recent years, the country has vigorously promoted the development of automobiles and has given great support in policies. Automobile-related technologies have also made rapid progress and are changing with each passing day. However, battery power loss prevention technology has not been effectively developed. The main reason is that the existing technology has insufficient promotion advantages in design costs and technical solutions, such as:

[0003] 1. If the main power switch of the vehicle is not turned off when it is parked for a long time, the battery will continue to discharge until it is exhausted, which seriously shortens the battery life. Especially in the field of heavy trucks, due to the widespread modification in the external market, the static current of the vehicle often exceeds the design standard, which increases the risk of battery exhaustion.

[0004] 2. Although new energy vehicles are equipped with intelligent charging strategies, they may fail to function in special situations such as high and low voltage system failures or power battery power failure. In addition, there are safety hazards in the intelligent charging process, such as the vehicle being accidentally high voltage during inspection or maintenance by the user.

[0005] 3. As for the problem of battery power shortage, currently only when users report to after-sales service can they know that the vehicle is low on power. As for the problem of battery shortage prevention, it mainly depends on the user's own use and the inspection of the whole vehicle, which has defects such as high cost and hysteresis;

[0006] 4. Lead-acid batteries lack a built-in battery management system (BMS), so they cannot monitor the remaining capacity (SOC) in real time and request recharging autonomously like lithium-ion batteries. They need to rely on a third party to monitor the battery voltage. At the same time, the battery voltage varies under different ambient temperatures, so the remaining battery capacity cannot be accurately identified. There is currently no effective solution to the above problems. Summary of the invention

[0026] Otherwise, proceed to the next step of priority determination.

[0027] As the preferred choice, otherwise, the next step of priority determination is performed, including:

[0028] Setting the parking duration as the fourth priority judgment condition;

[0029] When it is determined that the parking time exceeds a preset first time threshold, a command is issued to establish a handshake communication between the T-BOX and the BCM;

[0030] If the handshake is successful, the platform will remind the user: Please turn off the main power switch in time to avoid battery depletion;

[0031] On the contrary, if the handshake is unsuccessful, no reminder will be given and it will be judged that the main power switch is in the off state.

[0032] As a preferred method, otherwise, after the next step of priority determination, the following steps are also included:

[0033] Setting the parking duration as the fourth priority judgment condition;

[0034] When it is determined that the ambient temperature is lower than the preset temperature threshold and the parking time exceeds the preset second time threshold, a command is issued to start the T-BOX to establish handshake communication with the BCM;

[0035] If the handshake is successful, the platform will remind the user: Please turn off the main power switch in time to avoid battery depletion;

[0036] If the handshake is unsuccessful, no reminder will be given and it will be judged that the main power switch is in the off state.

[0037] As a preferred method, otherwise, after the next step of priority determination, the following steps are also included:

[0038] When it is determined that the ambient temperature is higher than the preset temperature threshold, and the battery voltage is again determined to be lower than the preset voltage threshold, a command is issued to start the T-BOX to establish handshake communication with the BCM;

[0039] If the handshake is successful, the platform will remind the user: Please turn off the main power switch in time to avoid battery depletion;

[0040] If the handshake is unsuccessful, no reminder will be given and it will be judged that the main power switch is in the off state.

[0041] In order to achieve the above-mentioned purpose, according to another aspect of the present application, a lead-acid battery power shortage prevention monitoring and control system is provided.

[0042] The lead-acid battery power-loss prevention monitoring and control system according to the present application includes:

[0043] The acquisition module is used to collect the current status information of the vehicle; wherein the status information includes: the power status of the ON gear, the ambient temperature within a preset time, the battery voltage and the parking time;

[0044] A priority judgment module, used to input the status information into a preset priority judgment model and generate a corresponding information push instruction;

[0045] The information sending module is used to send reminder information to the client according to the information push instruction to prevent the battery from running out of power.

[0046] In order to achieve the above-mentioned purpose, according to another aspect of the present application, an electronic device is provided, which includes: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores a computer program executable by the at least one processor, and the computer program is executed by the at least one processor so that the at least one processor can execute the lead-acid battery anti-low power monitoring and control method described in any one of the present invention.

[0047] Beneficial effect: In the embodiment of the present application, an intelligent detection and judgment method is adopted to collect the current status information of the vehicle; wherein, the status information includes: ON gear power status, ambient temperature within a preset time, battery voltage and parking time; the status information is input into a preset priority judgment model to generate a corresponding information push instruction; a reminder message is sent to the client according to the information push instruction to prevent the battery from running out of power, thereby achieving the purpose of automatically detecting the battery status, thereby achieving the technical effects of protecting the battery, increasing the battery life and intelligent monitoring, and thus solving the current problem that if the main power switch of the vehicle is not turned off when it is parked for a long time, the battery will continue to discharge until it runs out of power, seriously shortening the battery life; especially in the field of heavy trucks, due to the widespread modification phenomenon in the external market, the static current of the vehicle often exceeds the design standard The problem of battery power shortage is that the user cannot accurately determine the battery power shortage, which increases the risk of battery power shortage. Although new energy vehicles are equipped with intelligent charging strategies, intelligent charging may fail in special situations such as high and low voltage system failures or power shortage of the power battery itself. In addition, there are safety hazards in the intelligent charging process, such as the accidental high voltage of the vehicle during user inspection or maintenance. As for the problem of battery power shortage, currently only users can know that the vehicle is short of power after feedback to after-sales service. As for the problem of power shortage, it mainly depends on the user's own use and the inspection of the vehicle, which has defects such as high cost and lag. Lead-acid batteries lack a built-in battery management system (BMS), so they cannot monitor the remaining power (SOC) in real time and request charging autonomously like lithium-ion batteries. They need to use a third party to monitor the battery voltage. At the same time, the battery voltage varies at different ambient temperatures, so the technical problem of the remaining battery power cannot be accurately identified.

[0048] Compared with the related prior art, the present invention has at least the following main technical advantages, and the beneficial effects of the present invention are:

[0049] 1. Easy operation, software-driven: This solution does not require complex changes to the vehicle hardware. Only through fine-tuning of the software can the intelligent anti-low-power monitoring of lead-acid batteries be realized, which greatly simplifies the implementation process, reduces costs, and has high system flexibility;

[0050] 2. Real-time monitoring and accurate early warning: By directly connecting the B+ terminal of the battery with T-BOX, it is not restricted by the state of the main power switch, and can realize all-weather monitoring of the remaining power of the battery, ensuring the real-time nature of the monitoring data, and providing a reliable basis for timely issuing of low-power early warnings;

[0051] 3. Intelligent judgment and effective protection: Through the handshake mechanism between T-BOX and BCM, the off state of the main power switch can be cleverly judged. When it is detected that the power is not turned off and meets certain conditions (such as long shutdown at low temperature, low voltage at normal temperature or long parking), the platform automatically sends a reminder to the user, effectively preventing the lead-acid battery from running out of power due to long-term discharge, and extending the service life of the battery;

[0052] 4. Strong environmental adaptability: The system takes full account of the impact of ambient temperature on battery performance, uses the positioning function of T-BOX combined with weather forecast data to accurately determine the vehicle's environment, so that the system can provide more intimate and personalized reminder services based on the battery characteristics under different environmental conditions, enhancing the user experience;

[0062] In addition, the terms "installed", "set", "provided with", "connected", "connected", and "socketed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0064] like Figure 1-2 As shown in Figures 4-5, according to an embodiment of the present invention, a lead-acid battery power shortage prevention monitoring and control method is provided, and the method includes the following steps S101 to S103:

[0065] Step S101, collecting the current status information of the vehicle; wherein the status information includes: the power status of the ON gear, the ambient temperature within a preset time, the battery voltage and the parking time;

[0066] It can achieve good vehicle data information collection effects, thus providing a data basis for subsequent processing or calculation.

[0067] Specifically, ON gear power status monitoring: When the vehicle is powered on, T-BOX will monitor the vehicle's power status in real time to determine whether the vehicle is in the ON gear. If the power is turned off in the ON gear, the system considers the vehicle to be stationary and proceeds to the next step of monitoring.

[0068] Ambient temperature collection: The system will obtain the ambient temperature within the preset time based on the temperature sensor inside the vehicle to ensure that the battery voltage monitoring threshold can be adjusted according to different temperature conditions.

[0069] Battery voltage detection: The system collects the battery voltage value in real time through T-BOX to monitor whether the voltage is lower than the set safety threshold. If the voltage is lower than the threshold, the system will issue an early warning to prompt the user to recharge.

[0070] Parking time record: T-BOX records the parking time of the vehicle. If the parking time exceeds the preset number of days, the system will automatically start the anti-power loss measures, judge the health status of the battery, and take handshake or other management measures.

[0071] Step S102: input the status information into a preset priority judgment model to generate a corresponding information push instruction;

[0072] It can achieve accurate judgment effect of priority, thereby improving the degree of intelligence.

[0073] Specifically, the priority judgment model input: the vehicle's current ON gear state, ambient temperature, battery voltage, parking time and other data will be input into the preset priority judgment model, and the system will assign different weights to these states according to different conditions. For example, battery voltage and parking time are assigned higher weights.

[0074] Generate judgment results: The priority model makes logical judgments based on the input status information. If the parking time exceeds 7 days, the ambient temperature is high or low, and the battery voltage is lower than the safety threshold, the system will determine that there is a high risk of power shortage. On the contrary, if the parking time is short and the voltage is normal, the system will determine that it is a low risk.

[0075] Generate information push instructions: Based on the priority judgment results, the system generates corresponding push instructions:

[0076] If the risk of power shortage is high, emergency information will be pushed to users and the backend management system to remind them to recharge immediately.

[0077] If the risk is low, push regular reminder information, such as informing the user to check the battery status regularly or start the vehicle for a short time.

[0078] Information push and execution strategy: In an emergency, the system can send reminders directly to the user's mobile phone APP or vehicle system screen, and notify the background monitoring system for follow-up.

[0079] At the same time, T-BOX can shake hands with BCM and start the intelligent charging strategy to ensure that the battery is not completely depleted.

[0080] Step S103: Send reminder information to the client according to the information push instruction to prevent the battery from running out of power.

[0081] It can achieve real-time information push effect, thereby ensuring that the client can know the status of the battery. At the same time, it can also achieve the effect of protecting the battery, thereby achieving the effect of increasing the service life.

[0082] According to an embodiment of the present invention, preferably, the current status information of the vehicle is collected; wherein the status information includes: the power status of the ON gear, the weather forecast within a preset time and the battery voltage, including:

[0083] The ON power state includes: power-on state and power-off state;

[0084] The ambient temperature within the preset time includes: the 24-hour weather forecast for the current area.

[0085] According to an embodiment of the present invention, preferably, the state information is input into a preset priority judgment model to generate a corresponding information push instruction, including:

[0086] Setting the ON power state as the first priority judgment condition;

[0087] When the ON gear power state is judged to be powered on, the vehicle is in a powered on state and the next step of judgment is stopped;

[0088] Otherwise, it is in the power-off state and performs the next priority determination.

[0089] Specifically, the first priority judgment condition (ON power status): When the system detects that the ON power is in the energized state, it means that the vehicle is currently in the powered-on state (the vehicle is started or running). At this time, the system will stop further judgment and there is no need to execute the anti-low power strategy.

[0090] When the system detects that the power supply in the ON position is in a power-off state, it means that the vehicle is in a power-off or stationary state. At this time, the system will continue to execute the next judgment and enter the second priority judgment condition.

[0091] The execution logic of the priority judgment model:

[0092] If the vehicle is powered on (powered state), there is no need to consider the problem of battery depletion, so all subsequent judgments are stopped and the system remains in standby mode until the vehicle is powered off.

[0093] If the vehicle loses power (power-off state), the system will decide whether to perform the anti-battery operation based on the next priority judgment (such as ambient temperature, battery voltage, parking time, etc.).

[0094] According to an embodiment of the present invention, preferably, on the contrary, after being in a power-off state and performing the next priority determination, the following steps are included:

[0095] Setting the battery voltage as the second priority judgment condition;

[0096] When it is determined that the battery voltage is lower than a preset voltage threshold, a reminder message is issued to inform the first user that the battery is about to run low and needs to be recharged in time;

[0097] Otherwise, proceed to the next step of priority determination.

[0098] Specifically, the second priority judgment condition (battery voltage):

[0099] When the system detects that the vehicle is in a power-off state, it continues to determine whether the battery voltage is lower than a preset voltage threshold (such as 24.6V or 24.0V).

[0100] If the battery voltage is lower than the preset threshold, the system will immediately send a reminder message to inform the user that the battery is about to run low, and prompt the first user (such as the car owner or maintenance personnel) to recharge in time.

[0101] If the battery voltage is higher than or equal to the preset threshold, the system will not issue a reminder, but will continue with the next priority judgment (such as ambient temperature or parking time judgment).

[0102] Push notifications:

[0103] When the battery voltage is lower than the threshold, the system will generate an emergency message and send it to the first user's mobile phone APP, car display, or push it through the background management platform to remind the user to take charging measures to avoid further battery depletion.

[0104] By setting the battery voltage as the second priority judgment condition, the system can intervene in time when the battery voltage is too low, reminding the user to perform necessary charging operations, thereby effectively reducing the risks caused by battery low power.

[0105] According to an embodiment of the present invention, preferably, on the contrary, after being in a power-off state and performing the next priority determination, the method further includes:

[0106] Setting the ambient temperature as the third priority judgment condition;

[0107] When the ambient temperature is lower than the preset temperature threshold, it is determined that the main power switch is on, and the platform reminds the user to turn it off, and the synchronous T-BOX restarts the timing;

[0108] Otherwise, proceed to the next step of priority determination.

[0109] Specifically, when the system detects that the vehicle is in a power-off state and the battery voltage is normal (not lower than a threshold), it enters the ambient temperature judgment step.

[0110] The system will compare the collected ambient temperature data with the preset temperature threshold.

[0111] If the ambient temperature is lower than the preset temperature threshold (such as 20°C or a specific value), the system determines that this state may cause increased battery loss, especially in low temperature environments where battery performance is greatly affected.

[0112] At this time, the system will think that the main power switch is still on, and remind the user through the platform to turn off the main power switch to reduce unnecessary battery consumption.

[0113] At the same time, the system will instruct T-BOX to restart the timing to monitor the parking time after the power is turned off, so as to implement more strategies to prevent power loss later.

[0114] If the ambient temperature is higher than or equal to the preset temperature threshold, it means that the ambient temperature has little impact on the battery, and the system will proceed to the next priority judgment (such as parking duration, etc.).

[0115] According to an embodiment of the present invention, preferably, otherwise, after the next step of priority determination, the following steps are performed:

[0116] Setting the parking duration as the fourth priority judgment condition;

[0117] When it is determined that the parking time exceeds a preset first time threshold, a command is issued to establish a handshake communication between the T-BOX and the BCM;

[0118] If the handshake is successful, the platform will remind the user: Please turn off the main power switch in time to avoid battery depletion;

[0119] On the contrary, if the handshake is unsuccessful, no reminder will be given and it will be judged that the main power switch is in the off state.

[0120] According to an embodiment of the present invention, preferably, on the contrary, after the next step of priority determination, the method further includes:

[0121] Setting the parking duration as the fourth priority judgment condition;

[0122] When it is determined that the ambient temperature is lower than the preset temperature threshold and the parking time exceeds the preset second time threshold, a command is issued to start the T-BOX to establish handshake communication with the BCM;

[0123] If the handshake is successful, the platform will remind the user: Please turn off the main power switch in time to avoid battery depletion;

[0124] If the handshake is unsuccessful, no reminder will be given and it will be judged that the main power switch is in the off state.

[0125] According to an embodiment of the present invention, preferably, on the contrary, after the next step of priority determination, the method further includes:

[0126] When it is determined that the ambient temperature is higher than the preset temperature threshold, and the battery voltage is again determined to be lower than the preset voltage threshold, a command is issued to start the T-BOX to establish handshake communication with the BCM;

[0127] If the handshake is successful, the platform will remind the user: Please turn off the main power switch in time to avoid battery depletion;

[0128] If the handshake is unsuccessful, no reminder will be given and it will be judged that the main power switch is in the off state.

[0129] The present invention can solve the problems in the prior art that a vehicle is parked for a long time and the main power switch is not turned off, resulting in battery depletion and affecting the service life of the battery, and can effectively improve the convenience and safety of vehicle use.

[0130] From the above description, it can be seen that the present application achieves the following technical effects:

[0131] In the embodiment of the present application, an intelligent detection and judgment method is adopted to collect the current status information of the vehicle; wherein, the status information includes: ON gear power status, ambient temperature within a preset time, battery voltage and parking time; the status information is input into a preset priority judgment model to generate a corresponding information push instruction; a reminder message is sent to the client according to the information push instruction to prevent the battery from running out of power, thereby achieving the purpose of automatically detecting the battery status, thereby achieving the technical effects of protecting the battery, increasing the battery life and intelligent monitoring, and further solving the current problem that if the main power switch of the vehicle is not turned off when it is parked for a long time, the battery will continue to discharge until it runs out of power, seriously shortening the battery life; especially in the field of heavy trucks, due to the widespread modification phenomenon in the external market, the static current of the vehicle often exceeds the design standard, and the battery life is greatly shortened. The risk of battery power shortage has been aggravated; although new energy vehicles are equipped with intelligent charging strategies, intelligent charging may fail in special situations such as high and low voltage system failures or power battery power shortage; in addition, there are safety hazards in the intelligent charging process, such as the vehicle accidentally being on high voltage during user inspection or maintenance; for the problem of battery power shortage, currently only users can know that the vehicle is low in power after feedback to after-sales service. For the problem of power shortage, it mainly depends on the user's own use and the inspection of the whole vehicle, which has defects such as high cost and lag; lead-acid batteries lack a built-in battery management system (BMS), and cannot monitor the remaining power (SOC) in real time and request charging autonomously like lithium-ion batteries. They need to use a third party to monitor the battery voltage. At the same time, the battery voltage varies at different ambient temperatures, so the technical problem of the remaining battery power cannot be accurately identified.

[0132] like Figure 3 As shown, in order to achieve the above purpose, according to another aspect of the present application, a lead-acid battery power-loss prevention monitoring and control system is provided. The lead-acid battery power-loss prevention monitoring and control system comprises:

[0133] The acquisition module 301 is used to acquire the current status information of the vehicle; wherein the status information includes: the power status of the ON gear, the ambient temperature within a preset time, the battery voltage and the parking time;

[0134] It can achieve good vehicle data information collection effects, thus providing a data basis for subsequent processing or calculation.

[0135] The priority determination module 302 is used to input the state information into a preset priority determination model and generate a corresponding information push instruction;

[0136] It can achieve accurate judgment effect of priority, thereby improving the degree of intelligence.

[0137] The information sending module 303 is used to send reminder information to the client according to the information push instruction to prevent the battery from running low.

[0138] It can achieve real-time information push effect, thereby ensuring that the client can know the status of the battery. At the same time, it can also achieve the effect of protecting the battery, thereby achieving the effect of increasing the service life.

[0139] From the above description, it can be seen that the present application achieves the following technical effects:

[0140] In the embodiment of the present application, an intelligent detection and judgment method is adopted to collect the current status information of the vehicle; wherein, the status information includes: ON gear power status, ambient temperature within a preset time, battery voltage and parking time; the status information is input into a preset priority judgment model to generate a corresponding information push instruction; a reminder message is sent to the client according to the information push instruction to prevent the battery from running out of power, thereby achieving the purpose of automatically detecting the battery status, thereby achieving the technical effects of protecting the battery, increasing the battery life and intelligent monitoring, and further solving the current problem that if the main power switch of the vehicle is not turned off when it is parked for a long time, the battery will continue to discharge until it runs out of power, seriously shortening the battery life; especially in the field of heavy trucks, due to the widespread modification phenomenon in the external market, the static current of the vehicle often exceeds the design standard, and the battery life is greatly shortened. The risk of battery power shortage has been aggravated; although new energy vehicles are equipped with intelligent charging strategies, intelligent charging may fail in special situations such as high and low voltage system failures or power battery power shortage; in addition, there are safety hazards in the intelligent charging process, such as the vehicle accidentally being on high voltage during user inspection or maintenance; for the problem of battery power shortage, currently only users can know that the vehicle is low in power after feedback to after-sales service. For the problem of power shortage, it mainly depends on the user's own use and the inspection of the whole vehicle, which has defects such as high cost and lag; lead-acid batteries lack a built-in battery management system (BMS), and cannot monitor the remaining power (SOC) in real time and request charging autonomously like lithium-ion batteries. They need to use a third party to monitor the battery voltage. At the same time, the battery voltage varies at different ambient temperatures, so the technical problem of the remaining battery power cannot be accurately identified.

[0141] Specifically, further explanation is given by the following examples;

[0142] Embodiment 1:

[0143] When the vehicle is parked for a long time, users tend to forget to turn off the main power switch. To prevent the battery from running out of power, the T-BOX terminal can push information to the corresponding platform to remind users. First, remind users to turn off the main power switch as soon as possible. Second, remind users that the lead-acid battery is about to run out of power and please replenish it in time. It can be divided into environmental monitoring and voltage collection, low voltage instant reminder, low temperature long parking warning, normal temperature low voltage warning and excessive long parking warning. The specific process is as follows:

[0144] Environmental monitoring and voltage collection: After the vehicle stops and the power is turned off (power is lost in the ON position), T-BOX starts timing and retrieves the 24-hour weather forecast for the current area. If the temperature is below -20℃ for more than 3 hours in a day, it is determined that the current temperature is below -20℃ and the voltage of the power supply end (lead-acid battery) is monitored simultaneously.

[0145] Low voltage instant reminder: Once the battery voltage is detected to be lower than 24.0V, the platform will immediately send an emergency reminder to the user: the battery is about to run out of power, please recharge in time;

[0146] Low temperature long parking warning: When T-BOX detects that the ambient temperature of the vehicle is lower than -20℃ and the parking time reaches 24 hours, T-BOX starts to establish handshake communication with BCM. If the handshake is successful, the platform will remind the user: Please turn off the main power switch in time to avoid battery power loss. If the handshake is unsuccessful, no reminder will be given and the main power switch will be judged to be off.

[0147] Normal temperature low voltage warning: When T-BOX detects that the ambient temperature of the vehicle is higher than -20℃ and the battery voltage is lower than 24.6V, T-BOX starts to establish handshake communication with BCM. If the handshake is successful, the platform will remind the user: Please turn off the main power switch in time to avoid battery power loss. If the handshake is unsuccessful, no reminder will be given and the main power switch will be judged to be off.

[0148] Overlong parking warning: When T-BOX detects that the parking time has reached 7 days, T-BOX starts to establish handshake communication with BCM. If the handshake is successful, the platform will remind the user: Please turn off the main power switch in time to avoid battery power loss. If the handshake is unsuccessful, no reminder will be given and the main power switch will be judged to be off.

[0149] In addition, in the above process, when T-BOX successfully establishes handshake communication with BCM, T-BOX will restart the timer. When the parking time reaches 24 hours again, the background will remind the user again: Please turn off the main power switch in time to avoid battery depletion. If the handshake fails, it is judged that the main power switch is in the off state, and the cycle will be repeated until the handshake fails and then stop.
