Description

Technical Field

[0001] The present application belongs to the field of battery detection, and in particular, relates to a real-time detection method, system, storage medium and program product for an automobile emergency power supply. Background Art

[0002] With the rapid development of the automobile industry and consumers' increasing attention to automobile safety and convenience, automobile starting emergency power supply technology has been widely used and studied. This technology provides car owners with an emergency solution when the vehicle cannot start normally, greatly improving the safety and convenience of the car.

[0003] The technology of automobile starting emergency power supply is widely used in various automobile scenarios. For example, in the cold winter, the vehicle may not start normally due to battery aging or low temperature environment causing battery performance degradation. At this time, the owner can use the emergency power supply to provide the vehicle with starting current to solve the starting problem. In addition, in scenarios such as long-distance travel and outdoor adventures, the emergency power supply can also provide continuous power supply for vehicle-mounted electronic equipment to meet the diverse needs of car owners.

[0004] However, since the emergency power supply is not used very frequently, long-term storage may cause the power of the emergency power supply to decay, resulting in the emergency power supply being unable to meet the owner's power needs when it is needed because it has been stored for too long. Or some car owners only check whether the emergency power supply is sufficient when they are not using it, which will make the owner inaccurately understand the real situation of the emergency power supply, thus affecting the use of the emergency power supply. Summary of the invention

[0005] The present application provides a method, system, storage medium and program product for real-time detection of an automobile emergency power supply, which are used to feed back the real status of the emergency power supply to the car owner through real-time detection of the emergency power supply, and to give an early warning when the emergency power supply does not meet the usage requirements, thereby improving the car owner's understanding of the real status of the emergency power supply and reducing the impact caused by the inaccurate status of the emergency power supply.

[0006] In a first aspect, the present application provides a real-time detection method for an automobile emergency power supply, and when it is determined that the emergency power supply is powered off, the resistance value of the emergency power supply detected by a multimeter is obtained;

[0007] Determine whether the resistance value is equal to the preset safety value. When the resistance value is equal to the preset safety value, it indicates that the emergency power supply has no leakage. When the resistance value is not equal to the preset safety value, it indicates that the emergency power supply has leakage.

[0008] If the resistance value is equal to the preset safety value, it is determined whether the remaining power is greater than the preset minimum power threshold, and the remaining power is the current power of the emergency power supply;

[0009] If the remaining power is greater than the preset minimum power threshold, determine the historically used device, which is the device powered by the emergency power supply. The historically used device includes the total power and the historical average usage time;

[0010] Determine the historical average power consumption based on the total power and the historical average usage time;

[0011] Determine whether the historical average power consumption is greater than the remaining power;

[0012] If the historical average power consumption is greater than the remaining power, a first message is generated and sent to the mobile terminal bound to the emergency power supply, where the first message indicates that the emergency power supply is in a normal state;

[0013] If the historical average power consumption is not greater than the remaining power, a warning message is generated and sent to the mobile terminal, and the warning message indicates that the emergency power supply is insufficient.

[0014] By adopting the above technical solution, the resistance value can be measured by a multimeter to accurately diagnose whether the emergency power supply has leakage hazards. Once the resistance value deviates from the preset safety value, it means that the insulation performance is reduced, there is a risk of leakage or even short circuit, and the user must be warned in time. Secondly, by comparing the remaining power with the minimum power threshold, it can be judged whether the power of the emergency power supply meets the minimum power requirement for starting the vehicle. Thirdly, by analyzing the power and usage time of the historical equipment, the average power consumption can be accurately calculated, and then how long the emergency power supply can support the operation of the vehicle can be predicted. If the average power consumption is close to the remaining power, the user should be reminded to charge as soon as possible. Inform the user in real time through mobile terminals such as mobile phones to facilitate them to take corresponding measures. Through real-time detection of the emergency power supply, the real status of the emergency power supply is fed back to the owner, and an early warning is given when it does not meet the use requirements, so as to improve the owner's grasp of the real situation of the emergency power supply and reduce the impact caused by the inaccurate state of the emergency power supply.

[0015] In combination with some embodiments of the first aspect, in some embodiments, after generating and sending a warning message to the mobile terminal if the historical average power consumption is not greater than the remaining power, the method further includes:

[0016] If the resistance value is not equal to the preset safety value, second information is generated and sent to the mobile terminal, and the second information indicates that the emergency power supply is leaking.

[0017] By adopting the above technical solution, the system will directly send an alarm to the user when a leakage is detected, prompting them to carry out maintenance to prevent leakage from causing secondary disasters such as fire and explosion that endanger the safety of people and vehicles. On the other hand, even if the emergency power supply is sufficient, once there is a hidden danger of leakage, it must not be taken lightly. Leakage will accelerate power loss and shorten the power supply time. In addition, the temperature of the leakage site will continue to rise, and there is a risk of thermal runaway. Therefore, the system puts leakage diagnosis in the first place, and immediately issues an alarm once it is discovered to avoid a sharp increase in risks.

[0018] In combination with some embodiments of the first aspect, in some embodiments, if the resistance value is equal to the preset safety value, determining whether the remaining power is greater than a preset minimum power threshold specifically includes:

[0019] If the resistance value is equal to the preset safety value, the historical usage record of the emergency power supply is obtained, and the historical usage record includes a number of usage tags and the usage duration corresponding to the usage tags;

[0020] Eliminate overtime usage labels corresponding to usage durations longer than the preset duration;

[0021] Delete the usage record corresponding to the timed usage tag in the historical usage record to obtain several alternative usage records;

[0022] Determine a number of power usage corresponding to all the number of alternative usage records;

[0023] Determine the lowest power usage among the plurality of power usage as the preset minimum power usage;

[0024] Determine whether the remaining power is greater than a preset minimum power threshold.

[0025] By adopting the above technical solution, first of all, the system will regularly record each discharge process of the emergency power supply, including label data such as usage period, duration, start and end power, etc. Secondly, the system will eliminate atypical samples with abnormally long discharge time, which are samples that are only used to start the car. Extract representative power consumption data. Thirdly, the system selects the lowest discharge amount from these typical records as the minimum power threshold of the emergency power supply. Since this threshold is extracted from real massive power consumption data, it can objectively reflect the actual power demand of the emergency power supply. Whenever the system accumulates new power consumption records, the minimum power threshold will be recalculated. In this way, you can understand the minimum power consumption required by the user when using the emergency power supply to power other devices in the car. Provides accurate data for subsequent energy replenishment operations.

[0026] In combination with some embodiments of the first aspect, in some embodiments, determining the lowest power usage among the plurality of power usage as the preset minimum power usage specifically includes:

[0027] Calculate a number of usage voltages corresponding to all a number of alternative usage records;

[0028] Deleting the operating voltages that are greater than the preset voltage from the plurality of operating voltages to obtain a plurality of confident operating voltages;

[0029] The lowest power usage value among the power usage values ​​corresponding to the plurality of confident power usage voltages is determined as the preset minimum power usage value.

[0030] By adopting the above technical solution, after extracting the typical discharge record, the system will also examine the voltage level of the discharge segment. Since the battery voltage is closely related to the state of charge, the voltage level can reflect the battery usage status from the side. If the voltage is greater than the preset voltage, it means that the emergency power supply is starting the vehicle at this time; if the voltage is not greater than the preset voltage, it means that the user is using the emergency power supply to power other devices at this time. Such data screening can provide accurate data reference for subsequent operations.

[0031] In combination with some embodiments of the first aspect, in some embodiments, after generating first information and sending it to a mobile terminal bound to the emergency power supply if the historical average power consumption is greater than the remaining power, the method further includes:

[0032] Obtain the last charging data of the emergency power supply, including charging time, charging duration, charging start power and charging completion power;

[0033] The charging rate is obtained by dividing the replenished power by the charging time. The replenished power is the difference between the power at the end of charging and the power at the beginning of charging.

[0034] If it is determined that the charging rate is greater than the preset healthy charging rate, a charging cycle is determined, where the charging cycle is the date difference between the current time point and the charging time point;

[0035] Send the charging cycle to the mobile terminal.

[0036] By adopting the above technical solution, using the start and end power, duration and other data of the last charge, the average charging rate is calculated, and compared with the standard value, the health status of the emergency power supply can be determined. If the average charging rate is greater than the preset healthy charging rate, it means that the emergency power supply is in good health. Based on the time difference between this charge and the last charge, the charging cycle is automatically calculated, providing a basis for the user to choose the charging time in the future, thereby improving the user's charging efficiency for the emergency power supply.

[0037] In conjunction with some embodiments of the first aspect, in some embodiments, after sending the charging cycle to the mobile terminal, the method further includes:

[0038] When it is determined that the charging rate is not greater than the preset healthy charging rate, third information is generated and sent to the mobile terminal, where the third information is information indicating that the emergency power supply is healthy attenuated.

[0039] By adopting the above technical solution, if the average charging rate is not greater than the preset healthy charging rate, it means that the health status of the emergency power supply is poor. Then the system will generate the third information in time and send the third information to the mobile terminal to remind the user to repair or replace the emergency power supply to avoid the failure to meet the user's needs during use, thereby improving the owner's understanding of the real status of the emergency power supply.

[0040] In conjunction with some embodiments of the first aspect, in some embodiments, after sending the charging cycle to the mobile terminal, the method further includes:

[0041] Generate an initial charging calendar and mark the current time point in the charging calendar;

[0042] Mark all charging time points after the current time point in the charging calendar according to the charging cycle to obtain a recommended charging calendar;

[0043] The recommended charging calendar is sent to the mobile terminal.

[0044] By adopting the above technical solution, the charging plan for the future period is automatically generated using historical charging data and current power status. First, the system will refer to the past charging cycles of the emergency power supply and mark the time nodes of each charging on the calendar. Then the system will determine the best time for the next charging and mark it at the corresponding position on the calendar. It can improve the efficiency of users charging the emergency power supply.

[0045] In a second aspect, an embodiment of the present application provides a system, the system comprising: one or more processors and a memory; the memory is coupled to the one or more processors, the memory is used to store computer program code, the computer program code comprises computer instructions, and the one or more processors call the computer instructions so that the system executes the method described in the first aspect and any possible implementation method of the first aspect.

[0046] In a third aspect, an embodiment of the present application provides a computer-readable storage medium, comprising instructions, which, when executed on a system, causes the system to execute the method described in the first aspect and any possible implementation of the first aspect.

[0047] In a fourth aspect, an embodiment of the present application provides a computer program product, characterized in that when the computer program product runs on a system, the system executes the method described in any possible implementation manner in the first aspect.

By measuring the resistance value with a multimeter, it is possible to accurately diagnose whether the emergency power supply has a leakage hazard. Once the resistance value deviates from the preset safety value, it means that the insulation performance is reduced, and there is a risk of leakage or even short circuit, and a warning must be issued to the user in a timely manner. Secondly, by comparing the remaining power with the minimum power threshold, it can be determined whether the power of the emergency power supply meets the minimum power requirement for starting the vehicle. Thirdly, by analyzing the power and usage time of the historically used equipment, the average power consumption can be accurately calculated, and then the emergency power supply can be predicted to support the operation of the vehicle for a long time.

[0055] The terms used in the following embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to be used as limitations to the present application. As used in the specification and appended claims of the present application, the singular expressions "one", "a kind of", "said", "above", "the" and "this" are intended to also include plural expressions, unless there is a clear indication to the contrary in the context. It should also be understood that the term "and / or" used in the present application refers to any or all possible combinations comprising one or more listed items.

[0056] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0057] An application scenario of an embodiment of the present application is described below:

[0058] With the rapid development of the automobile industry, car owners have put forward higher requirements for the safety and convenience of cars. The automobile starting emergency power supply technology came into being, providing car owners with a backup solution when the vehicle cannot start normally, greatly improving the reliability and practicality of the car. However, due to the relatively low frequency of use of emergency power supply, many car owners tend to neglect the inspection and maintenance of its status in daily use, resulting in the emergency power supply failing to play its due role at critical moments.

[0059] Imagine a car owner plans to go on a long-distance self-driving tour. The night before departure, he specially checked the power of the car's emergency power supply and found that the power display was full, so he set off with confidence. During the journey, the car owner drove the car through a rugged mountain road. The violent turbulence of the car caused the car battery wiring to loosen, making it impossible for the car to start normally. The owner took out the emergency power supply and prepared to use the emergency power supply to power the car battery to help the car start, but found that although the emergency power supply showed sufficient power, in fact, due to long-term storage, the battery had decayed and the output current could not meet the needs of starting the car.

[0060] At this point, the car owner realized that the power display on the surface of the emergency power supply alone is not enough to fully judge the health of the emergency power supply. As the core component of the emergency power supply, the performance of the battery directly determines the reliability and durability of the emergency power supply. If the key parameters such as the internal resistance and voltage of the emergency power supply can be monitored in real time, and its performance trend can be intelligently analyzed based on the historical usage data of the emergency power supply, the real status of the emergency power supply can be more accurately grasped, and potential fault hazards can be discovered and resolved in a timely manner. For example, when the internal resistance of the battery is detected to have increased abnormally, the system can determine that the battery may have problems such as sulfation and plate damage, and prompt the user to repair or replace it to avoid the emergency power supply "falling off the chain" at a critical moment.

[0061] At the same time, it is often difficult for car owners to accurately grasp the charging timing and frequency of the emergency power supply in daily use. If the emergency power supply is in a low-power state for a long time, the self-discharge of the battery will accelerate and the capacity will gradually decay; if the emergency power supply is charged too frequently, it may aggravate the aging of the battery and shorten its service life. Therefore, if the emergency power supply can intelligently predict the best time for the next charge based on the car owner's driving habits and mileage, and remind the car owner to charge and maintain it in time, it can maximize the service life of the emergency power supply and ensure that it performs at its best at critical moments.

[0062] In order to solve the above technical problems, the present application provides a real-time detection method, system, storage medium and product program for an automobile emergency power supply, which is used to feed back the real status of the emergency power supply to the car owner through real-time detection of the emergency power supply, and to give early warning when it does not meet the usage requirements, thereby improving the car owner's understanding of the real situation of the emergency power supply and reducing the impact caused by the inaccurate status of the emergency power supply.

[0063] Combine the following Figure 1 , a real-time detection method for an automobile emergency power supply in this application is described:

[0064] See also Figure 1 , which is a flow chart of a method for real-time detection of an automobile emergency power supply in an embodiment of the present application.

[0065] S101. When it is determined that the emergency power supply is powered off, obtain a resistance value of the emergency power supply detected by a multimeter;

[0066] The system first needs to determine whether the emergency power supply is in a power-off state. This can be achieved by detecting the output voltage of the emergency power supply. If the output voltage is zero, it means that the emergency power supply has been powered off. After determining that the emergency power supply is powered off, the system needs to use a multimeter to measure the internal resistance of the emergency power supply. The multimeter is a common electrical measuring instrument that can easily measure circuit parameters such as voltage, current, and resistance. The system can read the internal resistance of the emergency power supply by controlling the probe of the multimeter to contact the positive and negative poles of the emergency power supply and switching to the resistance measurement position. For example, the rated voltage of a certain emergency power supply is 12V and the rated capacity is 20Ah. When the system detects that its output voltage is 0V, it determines that the emergency power supply has been powered off. At this time, the system uses a multimeter to measure its internal resistance value as 50mΩ, and passes this value to the subsequent steps for analysis and diagnosis.

[0067] S102, determining whether the resistance value is equal to a preset safety value;

[0068] The system determines whether the resistance value is equal to the preset safety value. When the resistance value is equal to the preset safety value, it indicates that the emergency power supply has no leakage. When the resistance value is not equal to the preset safety value, it indicates that the emergency power supply has leakage.

[0069] After obtaining the internal resistance value of the emergency power supply, the system needs to compare it with the preset safety threshold to determine whether the emergency power supply has a leakage risk. Leakage refers to the leakage of current from the normal conductive circuit, flowing through the human body or other conductive objects, which may cause serious safety accidents such as electric shock and fire. The internal resistance value of the emergency power supply is an important indicator for evaluating its insulation performance and leakage risk. When the internal resistance value is much higher than the safety threshold, it means that the insulation of the emergency power supply is good and there is no leakage risk; when the internal resistance value is close to or lower than the safety threshold, it means that the insulation layer may have aged and damaged, and there is a leakage risk, and the user needs to be warned in time for maintenance or replacement. For example, according to industry standards, the safety internal resistance threshold of a 12V lead-acid battery is usually set at 1Ω. If the system detects that the internal resistance value of the emergency power supply is 50mΩ, which is much lower than the safety threshold of 1Ω, it can be determined that the emergency power supply has no leakage risk and has good insulation performance. Through this step, the system can automatically screen out emergency power supplies with reduced insulation performance, eliminate leakage risks, and ensure the safety of power use for vehicles and personnel.

[0070] S103, generating second information and sending the second information to the mobile terminal;

[0071] If the resistance value is not equal to the preset safety value, second information is generated and sent to the mobile terminal, and the second information indicates that the emergency power supply is leaking.

[0072] If the system determines that the internal resistance of the emergency power supply is lower than the preset safety threshold, it means that the emergency power supply has a leakage risk and needs to remind the user in time to deal with it. To achieve this goal, the system will automatically generate a warning message and send it to the mobile terminal bound to the emergency power supply through the wireless communication network, such as the owner's smartphone or the in-vehicle central control screen. The warning message usually contains key information such as the model, internal resistance value, and fault judgment result of the emergency power supply, and will also give corresponding maintenance suggestions, such as stopping use, timely repair or replacement. For example, when the system detects that the internal resistance of an emergency power supply is 0.5Ω, which is lower than the safety threshold of 1Ω, a warning message will be generated: "Warning! Your emergency power supply (model: XX-500) has an insulation resistance of only 0.5Ω, and there is a risk of leakage. Please stop using it immediately and send it for repair or replacement as soon as possible!" The system sends this message to the owner's smartphone through the cellular network, and a striking prompt box pops up on the phone screen to attract the owner's attention. In this way, the system can ensure that the safety hazards of the emergency power supply are notified to the owner as soon as possible, avoid various safety accidents caused by leakage, and improve the safety and reliability of vehicle use.

[0073] S104, determining whether the remaining power is greater than a preset minimum power threshold;

[0074] If the resistance value is equal to the preset safety value, then determine whether the remaining power is greater than the preset minimum power threshold, and the remaining power is the current power of the emergency power supply. Specifically: If the resistance value is equal to the preset safety value, then obtain the historical usage record of the emergency power supply, which includes several usage tags and the usage duration corresponding to the usage tags;

[0075] Eliminate overtime usage labels corresponding to usage durations longer than the preset duration;

[0076] Delete the usage record corresponding to the timed usage tag in the historical usage record to obtain several alternative usage records;

[0077] Determine a number of power usage corresponding to all the number of alternative usage records;

[0078] Determine the lowest power usage among the plurality of power usage as the preset minimum power usage;

[0079] Determine whether the remaining power is greater than a preset minimum power threshold.

[0080] After confirming that there is no risk of leakage in the emergency power supply, the system needs to further determine whether the remaining power of the emergency power supply is sufficient. The remaining power refers to the current available power of the emergency power supply, which directly determines its endurance and power supply capacity. In order to ensure that the emergency power supply can work normally at a critical moment, the system needs to compare the remaining power with the preset minimum power threshold. If the remaining power is higher than the minimum power threshold, it means that the emergency power supply currently has sufficient power to meet the subsequent emergency startup or equipment power supply needs; if the remaining power is lower than the minimum power threshold, it means that the emergency power supply is already in a power-deficient state, and the endurance and output capacity will be greatly reduced, and it needs to be charged or replaced in time. For example, the rated capacity of an emergency power supply is 20Ah, and the system sets its minimum power threshold to 30%, that is, 6Ah. When the system detects that the remaining power of the emergency power supply is 8Ah, which is higher than the minimum threshold of 6Ah, it can be determined that its power is still sufficient. In order to improve the rationality of the minimum power threshold, the system will also dynamically adjust the threshold. Specifically, the system will regularly obtain the historical usage records of the emergency power supply, including the start and end time of each use, the duration of each use, etc., and then analyze and screen these data, eliminate some abnormal and long usage records, extract recent typical usage scenarios, calculate the average power consumption of the emergency power supply in each scenario, and use the minimum power consumption as the minimum power threshold. Through this adaptive adjustment strategy, the system can customize the optimal power management plan for each emergency power supply according to the actual use of the car by the owner, reduce power waste and the risk of power shortage, and extend the service life of the emergency power supply.

[0081] S105, determining historically used equipment;

[0082] If the remaining power is greater than the preset minimum power threshold, the historically used device is determined. The historically used device is the device powered by the emergency power supply. The historically used device includes the total power and the historical average usage time.

[0083] If the system determines that the remaining power of the emergency power supply is sufficient, its actual power supply capacity can be further evaluated. The power supply capacity of the emergency power supply depends not only on the remaining power, but also on the power of the connected electrical equipment. In order to comprehensively evaluate the status of the emergency power supply, the system needs to determine the electrical equipment that has been connected to it in history, mainly including the rated power of these equipment and the average use time and other parameters. The system can analyze the historical work log of the emergency power supply intelligent control module, extract the key data such as the device model, access time, disconnection time, and power-on current recorded for each connection, and then calculate the rated power and average use time of each device. For example, the system found that the emergency power supply has supplied power to three devices in the past week, namely: car refrigerator (rated power 60W, average use 2 hours), car air purifier (rated power 30W, average use 1.5 hours), car vacuum cleaner (rated power 100W, average use 0.5 hours). Through this step, the system can fully understand the actual use and load characteristics of the emergency power supply, laying the foundation for the subsequent power supply capacity evaluation.

[0084] S106, determining the historical average power consumption according to the total power and the historical average usage time;

[0085] After determining the historical use equipment of the emergency power supply, the system needs to further calculate its average power consumption on these equipment. Average power consumption refers to the average power provided by the emergency power supply to the power-consuming equipment per unit time. It comprehensively considers the power and usage time of the equipment, and can more accurately reflect the actual power supply intensity of the emergency power supply. The system first needs to add up the rated power of all historically used equipment to get the total power, then add up the average usage time of each equipment to get the total usage time, and finally multiply the total power by the total usage time to get the total power consumption of the emergency power supply on these equipment. Divide the total power consumption by the number of used equipment to get the average power consumption. For example, for the above three historically used equipment, the total power is 60W+30W+100W=190W, the total usage time is 2h+1.5h+0.5h=4h, the total power consumption is 190W×4h=760Wh, and the average power consumption is 760Wh÷3=253.3Wh. This means that the emergency power supply consumes an average of 253.3Wh of electricity per hour when connected to these three devices. Through this step, the system can quantitatively evaluate the actual power supply strength of the emergency power supply, determine whether it meets the power requirements of common devices, and predict its battery life under different loads.

[0086] S107, determining whether the historical average power consumption is greater than the remaining power;

[0087] After obtaining the average power consumption of the emergency power supply, the system needs to compare it with the remaining power to determine whether the emergency power supply can meet the subsequent power supply needs. If the average power consumption is greater than the remaining power, it means that the remaining power of the emergency power supply cannot support the average working time of the historically used equipment. Once these devices are connected, the emergency power supply will soon run out of power and shut down, and it will not be able to complete the established power supply task. On the contrary, if the average power consumption is less than or equal to the remaining power, it means that the power of the emergency power supply is still sufficient to maintain the normal operation of the historically used equipment and has a certain endurance. For example, the rated voltage of an emergency power supply is 12V, the rated capacity is 20Ah, and the current remaining power is 10Ah, that is, 120Wh (12V×10Ah=120Wh). If its historical average power consumption is 253.3Wh, which is much higher than the remaining power of 120Wh, the system can determine that the emergency power supply cannot currently meet the power supply needs of common devices, and even if these devices are connected, it will soon run out of power. Through this step, the system can accurately evaluate its current endurance and power supply risks based on the actual status of the emergency power supply, and provide targeted power use suggestions for car owners.

[0088] S108, generating first information and sending it to a mobile terminal bound to the emergency power supply;

[0089] If the historical average power consumption is greater than the remaining power, first information is generated and sent to the mobile terminal bound to the emergency power supply, and the first information indicates that the emergency power supply is in a normal state.

[0090] If the system determines that the remaining power of the emergency power supply is higher than the average power consumption, it means that the emergency power supply is currently in good condition and can be used normally. In order to let the car owner know this situation in time, the system will automatically generate a status notification message and send it to the mobile terminal bound to the emergency power supply, such as the car owner's smartphone or the car's central control screen. The message usually contains key information such as the model of the emergency power supply, the remaining power, and the estimated endurance time. At the same time, it will also give some usage tips and maintenance suggestions, such as proper charging and regular inspections. For example, when the system detects that the remaining power of a certain emergency power supply is 10Ah, which is higher than the average power consumption of 8Ah, it will generate a status message: "Your emergency power supply (model: XX-500) currently has a power of 10Ah, is in good condition, and can be used normally. Under the current load, it is expected to continue to supply power for 1.2 hours. It is recommended to charge it in time after use and perform a health check on the battery once a month." The system sends this message to the car owner's smartphone through the cellular network and displays a striking prompt icon on the phone screen for the car owner to view in time. In this way, the system can allow car owners to grasp the status and endurance of the emergency power supply at any time, reasonably arrange the use and maintenance of the power supply, and extend the service life of the battery.

[0091] S109: Generate warning information and send it to the mobile terminal.

[0092] If the historical average power consumption is not greater than the remaining power, an early warning message is generated and sent to the mobile terminal, and the early warning message indicates that the emergency power supply is insufficient. Or if the remaining power is not greater than the preset minimum power threshold, an early warning message is generated and sent to the mobile terminal, and the early warning message indicates that the emergency power supply is insufficient.

[0093] If the system determines that the remaining power of the emergency power supply is lower than the average power consumption, it means that the emergency power supply is already in a state of power shortage and cannot maintain the normal power supply of the historically used equipment. Continuing to use it may cause problems such as power failure and battery damage, and the owner needs to be reminded to take countermeasures in time. To this end, the system will automatically generate an early warning message and push it to the owner's mobile terminal through the mobile network. The message usually contains key data such as the model of the emergency power supply, the remaining power, and the estimated available time. At the same time, it will also give operational suggestions such as cutting off unnecessary power-consuming equipment and charging as soon as possible, prompting the owner to restore the normal power supply capacity of the power supply as soon as possible. For example, when the system detects that the remaining power of an emergency power supply is only 2Ah, which is much lower than the average power consumption of 8Ah, it will generate an early warning message: "Warning! Your emergency power supply (model: XX-500) is seriously low on power, with only 2Ah remaining, and is expected to continue to supply power for up to 15 minutes! Please immediately turn off high-power devices such as the vehicle refrigerator and air purifier to reduce unnecessary power consumption, and charge the emergency power supply as soon as possible to avoid affecting subsequent use." The system marks this message as high priority and pushes it to the owner through instant messaging software, while triggering the vibration and prompt sound of the mobile terminal to attract the owner's attention. Through this early warning mechanism, the system can avoid various problems caused by unexpected power shortages of the emergency power supply, ensure the stable power supply of key vehicle equipment, and improve the safety and reliability of vehicle use.

[0094] The above embodiments have the following beneficial effects:

[0095] By measuring the resistance value with a multimeter, it is possible to accurately diagnose whether the emergency power supply has leakage hazards. Once the resistance value deviates from the preset safety value, it means that the insulation performance is reduced, there is a risk of leakage or even short circuit, and the user must be warned in time. Secondly, by comparing the remaining power with the minimum power threshold, it can be determined whether the power of the emergency power supply meets the minimum power requirement for starting the vehicle. Thirdly, by analyzing the power and usage time of the historically used equipment, the average power consumption can be accurately calculated, and then how long the emergency power supply can support the operation of the vehicle can be predicted. If the average power consumption is close to the remaining power, the user should be reminded to charge as soon as possible. Inform the user in real time through mobile terminals such as mobile phones, so that they can take corresponding measures. Through real-time detection of the emergency power supply, the real status of the emergency power supply is fed back to the owner, and an early warning is given when it does not meet the use requirements, so as to improve the owner's grasp of the real status of the emergency power supply and reduce the impact caused by the inaccurate status of the emergency power supply.

[0096] When the system detects a leakage, it will directly send an alarm to the user, prompting them to perform maintenance to prevent leakage from causing secondary disasters such as fire and explosion that endanger the safety of people and vehicles. On the other hand, even if the emergency power supply is sufficient, once there is a hidden danger of leakage, it must not be taken lightly. Leakage will accelerate power loss and shorten the power supply time. In addition, the temperature of the leakage part will continue to rise, and there is a risk of thermal runaway. Therefore, the system puts leakage diagnosis in the first place, and immediately issues an alarm once it is discovered to avoid a sharp increase in risks.

[0097] First, the system will regularly record each discharge process of the emergency power supply, including labelled data such as usage period, duration, start and end power, etc. Secondly, the system will eliminate atypical samples with abnormally long discharge time, which are samples that are only used to start the car. Extract representative power consumption data. Thirdly, the system selects the lowest discharge amount from these typical records as the minimum power threshold of the emergency power supply. Since this threshold is extracted from real massive power consumption data, it can objectively reflect the actual power demand of the emergency power supply. Whenever the system accumulates new power consumption records, the minimum power threshold will be recalculated. In this way, you can understand the minimum power consumption required by the user when using the emergency power supply to power other devices in the car. Provides accurate data for subsequent energy replenishment operations.

[0098] After extracting typical discharge records, the system will also examine the voltage level of the discharge segment. Since the battery voltage is closely related to the state of charge, the voltage level can reflect the battery usage status from the side. If the voltage is greater than the preset voltage, it means that the emergency power supply is starting the vehicle at this time; if the voltage is not greater than the preset voltage, it means that the user is using the emergency power supply to power other devices at this time. Such data screening can provide accurate data reference for subsequent operations.

[0099] After the detection and warning of the above embodiment, the car owner can have a good grasp of the status of the emergency power supply at the current moment, and it is also necessary to grasp it in the future. Among them, the car owner may be most concerned about when the emergency power supply is charged and the health of the battery. Figure 2 , describes the method of planning the future replenishment of emergency power supply in this application:

[0100] See also Figure 2 , is another flow chart of a method for real-time detection of an automobile emergency power supply in an embodiment of the present application.

[0101] S201, obtaining the last charging data of the emergency power supply;

[0102] The system obtains the last charging data of the emergency power supply, which includes the charging time, charging duration, charging start power and charging completion power.

[0103] The system needs to read the key data of the last charge from the intelligent control module of the emergency power supply, mainly including parameters such as the starting time point, duration, starting power and completion power of charging. These data are usually automatically recorded in the memory of the control module after each charging process to form a charging log. The system can establish a communication connection with the control module by wired or wireless means, and send a data reading instruction to extract the relevant data items in the most recent charging log. For example, the last charge of an emergency power supply occurred at 14:30 on April 1, 2023, and lasted for 2 hours, during which the power increased from 20% to 100%. After the system successfully reads these data, it can pass them to the subsequent steps for analysis and calculation. By obtaining the historical charging data of the emergency power supply, the system can understand its typical charging characteristics and power change laws, and provide a decision-making basis for formulating a reasonable charging plan.

[0104] S202, dividing the replenished power by the charging time to obtain a charging rate;

[0105] The system divides the replenished power by the charging time to get the charging rate. The replenished power is the difference between the power at the end of charging and the power at the start of charging.

[0106] After obtaining the last charging data of the emergency power supply, the system needs to further calculate its average charging rate. The charging rate refers to the increment of battery power per unit time, which reflects the charging efficiency and acceptance capacity of the battery. To calculate the charging rate, the system must first calculate the net power obtained by the battery during this charging process, that is, the replenishment power. The replenishment power can be obtained by subtracting the power at the beginning of charging from the power at the end of charging. After obtaining the replenishment power, divide it by the duration of charging to get the average charging rate. For example, the charging data of the emergency power supply in the previous step shows that it was charged from 20% to 100% in 2 hours, and the replenishment power was 80% (100%-20%=80%), which is converted into a capacity of 80%×20Ah=16Ah. Dividing 16Ah by 2 hours, the average charging rate is 8A (16Ah÷2h=8A). This means that the emergency power supply can replenish 8 ampere-hours of power per hour on average. By calculating the average charging rate, the system can quantitatively evaluate the charging performance of the emergency power supply, laying the foundation for diagnosing the battery health status and predicting the charging time.

[0107] S203, determining a charging cycle when it is determined that the charging rate is greater than a preset healthy charging rate;

[0108] When the system determines that the charging rate is greater than the preset healthy charging rate, it determines the charging cycle, where the charging cycle is the date difference between the current time point and the charging time point.

[0109] After calculating the average charging rate of the emergency power supply, the system needs to compare it with the preset healthy charging rate threshold to determine the health status of the battery. The healthy charging rate is an empirical value given by experts or algorithms based on the material properties, capacity specifications and other parameters of the battery, representing the typical charging efficiency of this type of battery under normal conditions. When the actual average charging rate is higher than this healthy threshold, it means that the battery has good charging performance, there is no obvious aging or damage inside, and it can continue to be used safely. On the contrary, if the average charging rate is significantly lower than the healthy threshold, it means that the battery may have problems such as capacity decay and increased internal resistance, which need to be paid attention to. After confirming the health of the battery, the system also needs to analyze its charging cycle law. The charging cycle refers to the interval between two charging time points, which reflects the owner's habit of using and maintaining the battery. The system can calculate a charging cycle by subtracting the last charging time from the current time. For example, the healthy threshold is set to 5A. When the system finds that the average charging rate of the emergency power supply is 8A, it is higher than the healthy threshold, indicating that the battery performance is normal. At the same time, the system records that the current time is April 10, 2023, and the last charging time was April 1, a difference of 9 days, which means that the owner charges the emergency power supply once every 9 days on average. After mastering the health status and charging cycle of the battery, the system can predict the next best charging time and remind the owner to charge in time to extend the battery life.

[0110] S204, sending the charging cycle to the mobile terminal;

[0111] After determining the health status and charging cycle of the emergency power supply, the system needs to promptly inform the owner of the charging cycle information so that the owner can understand the usage patterns of the battery and reasonably arrange subsequent charging and discharging plans.

[0112] The system sends the charging cycle data to the mobile terminal bound to it, such as the owner's smartphone, smart watch, etc., through the vehicle communication module. After receiving the charging cycle data, the mobile terminal can intuitively display it to the owner in a graphical way, such as marking the time points of previous charging on the calendar interface and marking the length of the charging cycle with different colors or icons.

[0113] For example, a 9-day time progress bar is displayed on the screen, and each charging time point is marked with a green battery icon, so that the owner can see the battery charging pattern at a glance. The mobile terminal can also automatically calculate the next best charging date based on the charging cycle, and send a charging reminder to the owner when the date is approaching, such as "Your car emergency power supply has not been charged for 8 days. It is recommended to fully charge it tomorrow to ensure the best user experience." By visually presenting the battery charging cycle to the owner and giving thoughtful charging reminders, the system can guide the owner to develop good battery usage habits, slow down the battery aging rate, and improve the reliability of the vehicle emergency start.

[0114] S205. If it is determined that the charging rate is not greater than the preset healthy charging rate, generate third information and send the third information to the mobile terminal;

[0115] When determining that the charging rate is not greater than the preset healthy charging rate, the system generates third information and sends the third information to the mobile terminal, where the third information is information indicating the healthy attenuation of the emergency power supply.

[0116] If the system finds that the actual charging rate of the emergency power supply is lower than or equal to the health threshold after comparing the average charging rate and the health threshold, it means that the charging performance of the battery has declined significantly, and there may be hidden dangers such as capacity attenuation, short circuit, aging, etc. inside, which can no longer support normal use needs. At this time, the system will generate a warning status message to remind the owner that the battery health is worrying and needs to be dealt with in time. This information usually includes diagnostic data such as battery model specifications, measured charging rate, health rate threshold, attenuation percentage, etc., and also gives some disposal suggestions, such as stopping use and replacing as soon as possible. The system marks the battery attenuation information as high priority, pushes it to the owner's mobile terminal through instant messaging software, and pops up a striking prompt box on the terminal interface, accompanied by a warning sound to remind the owner to check. For example, when the system detects that the average charging rate of the emergency power supply is only 2A, which is lower than the healthy threshold of 5A, it will generate a warning text message: "Warning! The battery health of your emergency power supply (model: XX-500) has seriously declined, and the charging rate is only 40% of the rated value, which is far below the healthy standard. The battery may have problems such as capacity decay and increased internal resistance. It is recommended that you stop using the battery and go to the service station for inspection and replacement as soon as possible to avoid affecting driving safety." The system sends this information to the owner's mobile phone via SMS, and a red warning box pops up on the phone screen, and vibrates for 30 seconds to ensure that the owner pays attention. By actively warning of battery decay risks, the system can avoid problems such as vehicle paralysis caused by unexpected failure of the emergency power supply.

[0117] S206, generating an initial charging calendar, and marking the current time point in the charging calendar;

[0118] After learning the historical charging patterns and health status of the emergency power supply, the system also needs to look to the future and plan a long-term charging schedule for the owner so that the owner can intuitively understand the battery usage and maintenance cycle and make charging arrangements in advance. The system will use the current date as the starting point to generate an initial charging calendar view on the owner's mobile terminal calendar and mark the current time point with a special symbol. For example, the system creates a new calendar called "Emergency Power Supply Charging Management" in the calendar application of the owner's mobile phone, and marks the current date April 10, 2023 as a green dot, indicating that this is the starting point after the last charge. The owner can clearly see this starting mark on the calendar interface and intuitively perceive the starting point of the battery life cycle. After generating the initial charging calendar, the system builds a basic framework for battery energy management for the owner, which can continuously record and present the battery's charge and discharge status, and guide the owner to form regular battery usage habits.

[0119] S207: Mark all charging time points after the current time point in the charging calendar according to the charging cycle, obtain a recommended charging calendar, and send the recommended charging calendar to the mobile terminal.

[0120] Based on the initial charging calendar, the system needs to further predict the optimal charging time for the battery in the future to form a long-term battery energy planning plan. The system uses the charging cycle determined in step 203 as the interval and the current time of the initial charging calendar as the starting point to automatically calculate the end date of each subsequent charging cycle and mark these dates as recommended charging days on the calendar interface. For example, the system determines in step 203 that the owner's charging cycle is 9 days, and generates an initial charging calendar starting from April 10 in step 206. Then, according to the rule of a 9-day cycle, a series of future charging time points such as April 19, April 28, and May 7 can be calculated and marked on the calendar with a red battery icon. These charging time points form a long-term charging plan. Car owners can follow the map, arrange time in advance, and charge the battery regularly to achieve the best maintenance effect. After the system generates the charging calendar, it will automatically synchronize it to various mobile terminals bound to the car owner. The car owner can check the battery charging schedule for the next month or even a year at any time, which can not only avoid forgetting the charging time, but also reasonably plan the use of the vehicle and reduce the risk of emergency power consumption. In addition, the mobile terminal can also push charging reminder messages to the car owner the night before each recommended charging day according to the charging calendar, such as "Tomorrow is the recommended charging day for your car's emergency start battery. Please arrange time to fully charge the battery. I wish you a safe journey!" Such thoughtful reminders can not only help car owners develop a good habit of regular charging, but also extend the overall life of the battery.

[0121] The above embodiments have the following beneficial effects:

[0122] By using the start and end power, duration and other data of the last charge, the average charging rate is calculated and compared with the standard value to determine the health status of the emergency power supply. If the average charging rate is greater than the preset healthy charging rate, it means that the emergency power supply is in good health. Based on the time difference between this charge and the last charge, the charging cycle is automatically calculated to provide a basis for the user's future charging time selection and improve the user's charging efficiency for the emergency power supply.

[0123] If the average charging rate is not greater than the preset healthy charging rate, it means that the emergency power supply is in poor health. Then the system will generate the third information in time and send the third information to the mobile terminal to remind the user to repair or replace the emergency power supply to avoid the failure to meet the user's needs during use, thereby improving the owner's understanding of the real condition of the emergency power supply.

[0124] Using historical charging data and current power status, the system automatically generates a charging plan for the next period of time. First, the system will refer to the past charging cycles of the emergency power supply and mark the time nodes of each charging on the calendar. Then the system will determine the best time for the next charging and mark it at the corresponding position on the calendar. It can improve the efficiency of users charging the emergency power supply.
