Description

Technical Field

[0001] The present application relates to the technical field of emergency power supply devices, and particularly to an automatic energy-saving control method and system for an automotive emergency starting power supply. Background Art

[0002] An automotive emergency starting power supply is a portable starting power supply that integrates power supply and charging functions. The main characteristic function of this power supply is that it can help start a vehicle emergently when the vehicle cannot start due to a dead battery or other reasons. For example, when the vehicle battery has insufficient power, the vehicle owner can start the vehicle by connecting the automotive emergency starting power supply. During this process, the emergency starting power supply will provide sufficient electrical energy to the vehicle, enabling the vehicle's engine to operate normally. And the reason why this process can proceed smoothly mainly benefits from the lithium-ion battery inside the automotive emergency starting power supply. This kind of battery has characteristics such as high energy density, long life, and fast charging, and can provide a large amount of electrical energy in a short time.

[0003] In the related art, when the vehicle owner starts the vehicle, the emergency starting power supply will detect the voltage and current status of the vehicle battery. If the battery has insufficient power, the emergency starting power supply will immediately start and provide electrical energy to the vehicle through the internal lithium-ion battery. This process usually takes from a few seconds to several minutes, and the specific time depends on the degree of discharge of the vehicle battery and the capacity of the emergency starting power supply.

[0004] However, the output current and discharge duration of traditional automotive emergency starting power supplies are generally fixed (such as 200 - 400A, lasting for 3 seconds). However, in fact, there are differences in various performance parameters of vehicle batteries manufactured by different vehicle factories. This dual-fixed power supply method of the emergency starting power supply is difficult to meet the power supply requirements of vehicles with different performances. For vehicles that are easy to start with good performance, the current and duration may exceed the requirements and cause waste. For vehicles with poor performance that are difficult to start, the voltage and current may not reach the requirements and the starting may not be successful. Summary of the Invention

[0005] The present application provides an automatic energy-saving control method and system for an automotive emergency starting power supply, which can automatically adjust the output current and discharge duration according to the actual needs of the vehicle, not only saving electrical energy, but also improving the starting success rate by adjusting the current and discharge time when encountering vehicles with poor performance and difficult to start.

[0006] In a first aspect, the present application provides an automatic energy-saving control method for an automotive emergency starting power supply, which is applied to an automotive emergency starting power supply control system. The method includes:

[0007] After detecting a start instruction, control the automotive emergency starting power supply to discharge using an initial starting current, and record the initial discharge duration;

[0008] If it is detected that the initial discharge duration exceeds the preset time threshold and the vehicle fails to start successfully, the discharge is terminated;

[0009] Increase the initial starting current successively by a preset current increment to obtain one or more increment starting currents;

[0010] Discharge successively using the increment starting current, and detect whether the vehicle starts successfully under each increment starting current;

[0011] If so, stop increasing the initial starting current, and record the current increment starting current and the discharge duration;

[0012] If not, continue to use the next increment starting current to detect whether the vehicle starts successfully;

[0013] Stop discharging when it is detected that the increment starting current exceeds the preset current threshold, and give a fault warning.

[0014] Through the above embodiments, after detecting the start instruction, the system first discharges using the initial starting current and records the discharge duration. When the discharge duration exceeds the threshold and the vehicle fails to start successfully, the discharge is stopped. Then, the starting current is increased successively by a preset increment for discharging until the vehicle starts successfully or the current exceeds the threshold. By adaptively adjusting the starting current and the discharge duration, the system can automatically provide an appropriate starting current according to the actual starting requirements of different vehicles, achieving energy conservation while ensuring the starting success rate. For vehicles that are easy to start, waste of current and duration can be avoided; for vehicles that are difficult to start, the starting requirements can be met by increasing the current and extending the time, thus significantly improving the practicality and energy utilization efficiency of the automotive emergency starting power supply, saving electric energy and increasing the vehicle starting success rate.

[0015] In some embodiments, before the step of controlling the automotive emergency starting power supply to discharge using the initial starting current and recording the initial discharge duration after detecting the start instruction, the following steps are further included:

[0016] Monitor the starting data during the engine starting process within a preset time period, where the starting data includes voltage, current, and engine speed;

[0017] Construct a starting model based on the starting data;

[0018] Predict the required current range based on the real-time starting data and the starting model, where the required current range is the magnitude of the current required for the vehicle to start normally;

[0019] Set the lower limit value of the required current range as the value of the initial starting current.

[0020] Through the above embodiments, the system monitors the engine start-up data over a period of time, such as voltage, current, speed, etc., and constructs a start-up model based on this data to predict in real time the current range required for the current vehicle start-up. Taking the lower limit of this range as the initial start-up current can make the start-up current closer to the actual needs of the vehicle from the very beginning, further improving the start-up efficiency and success rate, making the start-up process more intelligent, and the effects in terms of energy conservation and speed increase will be more significant.

[0021] In some embodiments, before the step of controlling the automotive emergency start-up power supply to discharge using the initial start-up current and recording the initial discharge duration after detecting the start-up instruction, it further includes:

[0022] Display the initial start-up current and the status information of the automotive emergency start-up power supply through a display, where the status information is a factor affecting the normal operation of the automotive emergency start-up power supply;

[0023] Receive the current setting information input by the user, where the current setting information includes the current magnitude and the power supply duration;

[0024] Perform emergency power supply to the vehicle according to the current setting information.

[0025] Through the above embodiments, the system introduces a human-computer interaction function, displays information such as start-up current settings and power supply status in real time through a display, and supports the user to manually adjust the current magnitude and power supply duration, giving the user more right to know and control. The user can flexibly adjust according to their own experience and the current situation. Especially for the start-up of some special vehicle models or in extreme environments, this kind of manual intervention is particularly important, further improving the applicability of the automotive emergency start-up power supply.

[0026] In some embodiments, the step of receiving the current setting information input by the user specifically includes:

[0027] Integrate a voice recognition system to recognize the user's voice command;

[0028] Translate the voice command to obtain the current setting information.

[0029] Through the above embodiments, the system introduces a human-computer interaction function, uses voice recognition technology, and enables the user to control the start-up parameters through voice commands, further improving the convenience of user operation.

[0030] In some embodiments, after the step of displaying the initial start-up current and the status information of the automotive emergency start-up power supply through a display, it further includes:

[0031] Detect whether the power of the automotive emergency start-up power supply is lower than a preset power threshold;

[0032] If so, automatically connect to the vehicle battery for charging.

[0033] Through the above embodiments, the system automatically detects the power of the emergency start power supply. When the power is lower than the preset threshold, it actively connects to the vehicle battery for charging, which can ensure that the emergency power supply is always in a full power state or the best state, ready to start the vehicle emergently at any time, greatly improving the reliability and real-time availability of the start power supply, which is particularly important for vehicle owners who travel frequently and have high requirements for backup power supplies.

[0034] In some embodiments, after the step of controlling the automotive emergency start power supply to discharge using the initial start current and recording the initial discharge duration after detecting the start instruction, the method further includes:

[0035] Monitoring the battery temperature of the automotive emergency start power supply through a built-in temperature sensor;

[0036] After detecting that the battery temperature exceeds the preset safety threshold, disconnect the current and send a warning message to the display or the user terminal.

[0037] Through the above embodiments, the system monitors the battery temperature of the emergency power supply in real time through a built-in temperature sensor during the start-up process. Once the temperature exceeds the safety threshold, the current is immediately disconnected and a warning is issued. This overheat protection mechanism can effectively avoid the out-of-control of the battery temperature caused by too large start-up current, and prevent the battery from aging, bulging, etc. due to high temperature, which threatens the use safety and life. Especially for some large-displacement or high-power vehicle models, the instantaneous current load during start-up is relatively large, which is more likely to cause battery heating problems, thereby improving the use safety of the automotive emergency start power supply.

[0038] In some embodiments, after the step of stopping increasing the initial start current and recording the current incremental start current and discharge duration, the method further includes:

[0039] Obtaining and recording the current connected first vehicle information, where the first vehicle information includes the unique identification of the vehicle;

[0040] After connecting to the vehicle again next time and detecting the start instruction, obtaining the second vehicle information;

[0041] If the second vehicle information is the same as the first vehicle information, set the incremental start current as the new initial start current.

[0042] Through the above embodiments, for the repeated start of the same vehicle, after the first successful start, the optimal start current and vehicle information at that time will be recorded. The next time the same vehicle is connected, the previous optimal current will be directly set as the new initial start current. This enables the emergency start power supply to continuously accumulate and precipitate the best start parameters for each vehicle model, and improves the start efficiency and accuracy with the increase in the number of uses.

[0043] In a second aspect, the present application provides an emergency starting power supply control system for a vehicle, the system comprising: one or more processors and a memory;

[0044] The memory is coupled to the one or more processors, and the memory is used to store computer program code, the computer program code includes computer instructions, and the one or more processors call the computer instructions so that the system can implement an automatic energy-saving control method for an emergency starting power supply of a vehicle provided in the above embodiments, which will not be elaborated here.

[0045] In a third aspect, the present application provides a computer-readable storage medium, comprising instructions, when the instructions run on a system, enabling the system to implement an automatic energy-saving control method for an emergency starting power supply of a vehicle provided in the above embodiments, which will not be elaborated here.

[0046] In a fourth aspect, the present application provides a computer program product, when the computer program product runs on a system, enabling the system to implement an automatic energy-saving control method for an emergency starting power supply of a vehicle provided in the above embodiments, which will not be elaborated here.

[0047] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0048] 1. By adaptively adjusting the starting current and discharge duration, the system can automatically provide just the right starting current according to the actual starting requirements of different vehicles, achieving energy saving while ensuring the starting success rate. For vehicles that are easy to start, waste of current and duration can be avoided; for vehicles that are difficult to start, the starting requirements can be met by increasing the current and extending the time, thus significantly improving the practicality and energy utilization efficiency of the emergency starting power supply for a vehicle, saving electric energy and increasing the starting success rate of the vehicle.

[0049] 2. The system constructs a starting model based on the historical starting data of the engine to predict in real time the current range required for starting the current vehicle, and uses the lower limit of this range as the initial starting current, which can make the starting current closer to the actual requirements of the vehicle from the very beginning, further improving the starting efficiency and success rate. A human-machine interaction link can also be introduced, where information such as the starting current setting and power supply status is displayed in real time through a display, and the user is supported to manually adjust the current magnitude and power supply duration. At the same time, voice recognition technology can also be used to enable the user to control the starting parameters through voice commands. This human-machine collaboration method gives the user more right to know and control, and the user can flexibly adjust according to their own experience and the current situation.

[0050] 3. The system automatically detects the power of the emergency starting power supply. When the power is lower than the preset threshold, it actively connects to the vehicle battery for charging. It can also monitor the battery temperature of the emergency power supply in real time through the built-in temperature sensor during the starting process. Once the temperature exceeds the safety threshold, the current is immediately disconnected and a warning is issued, improving the safety and reliability of the starting power supply. In addition, when the system detects that the same vehicle is connected, it directly sets the optimal current of the previous time as the new initial starting current. This enables the emergency starting power supply to continuously accumulate and precipitate the best starting parameters for each vehicle model, and the starting efficiency and accuracy will continuously improve as the number of uses increases.

[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 limit the present application. As used in the specification and appended claims of the present application, the singular forms "a", "an", "the", "above-mentioned", "said", and "this" are also intended to include the plural forms, unless the context clearly indicates otherwise.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present application, unless otherwise stated, the meaning of "a plurality" is two or more.

[0057] An automotive emergency starting power supply is a portable starting power supply that integrates power supply and charging functions. The main characteristic function of this power supply is that it can emergently assist in starting the vehicle when the vehicle fails to start due to a dead battery or other reasons. At the same time, it can also provide charging services for digital devices such as mobile phones and tablets at any time and place. In practical applications, when the vehicle owner starts the vehicle, the emergency starting power supply will detect the voltage and current status of the vehicle battery. If the battery power is insufficient, the emergency starting power supply will be immediately activated and supply electrical energy to the vehicle through the internal lithium-ion battery. This process usually takes from a few seconds to a few minutes, and the specific time depends on the degree of battery discharge of the vehicle and the capacity of the emergency starting power supply.

[0058] Since the starting process of a vehicle requires a large current to drive the engine, and different vehicle models and engine types have different requirements for the starting current. And there has always been a problem with traditional automotive emergency starting power supplies, that is, their output current magnitude and discharge duration are fixed, which cannot well meet the actual requirements of the vehicle for starting current and discharge duration. This limitation often leads to starting failures or power waste, bringing many inconveniences to vehicle owners.

[0059] To solve the above problems, this application provides an automatic energy-saving control method and system for an automotive emergency starting power supply, which can first use the initial starting current for discharging and record the discharge duration after detecting the starting instruction. When the discharge duration exceeds the threshold and the vehicle fails to start successfully, stop discharging, and increase the starting current in preset increments for discharging until the vehicle starts successfully or the current exceeds the threshold. By adaptively adjusting the starting current and discharge duration, it can automatically provide just the right starting current according to the actual starting requirements of different vehicles, achieving energy conservation while ensuring the starting success rate. For vehicles that are easy to start, it can avoid waste of current and duration; for vehicles that are difficult to start, it can meet the starting requirements by increasing the current and extending the time, thus significantly improving the practicality and energy utilization efficiency of the automotive emergency starting power supply, saving electrical energy and increasing the starting success rate of the vehicle.

[0060] For easy understanding, the process of the method provided in this embodiment is described. Please refer to Figure 1 , which is a flow schematic diagram of an automatic energy-saving control method for an automotive emergency starting power supply in an embodiment of this application.

[0061] S101. After detecting the starting instruction, control the automotive emergency starting power supply to discharge using the initial starting current and record the initial discharge duration.

[0062] Specifically, when the car emergency starting power supply system receives a start command from the user, it will immediately control the car emergency starting power supply to start the discharge operation, and select a preset initial current value to discharge the car battery. This initial current is generally set based on the common car starting current requirements and the emergency starting power supply's own performance, with the aim of meeting the starting requirements of most cars as much as possible without causing excessive load on the power supply.

[0063] While discharging, the system will also start a timer to record the duration of discharge in real time, that is, the initial discharge duration. Generally speaking, if the car can be successfully started in a short time, it means that the initial current basically meets the starting requirements; on the contrary, if the car cannot be started after a certain time, it may be that the initial current is too small and needs to be further increased.

[0064] For example, the rated voltage of a certain emergency starting power supply is 12V, the rated current is 600A, and the initial current selected after comprehensive evaluation is 200A. When the user presses the start button, the system starts to discharge to the car battery at a constant current of 200A, and starts timing at the same time, recording the discharge time in real time, providing a decision basis for subsequent intelligent current adjustment.

[0065] S102: If it is detected that the initial discharge duration exceeds a preset time threshold and the vehicle fails to start successfully, the discharge is terminated.

[0066] After discharging the car battery with the initial starting current for a period of time, the system needs to determine whether the starting strategy needs to be adjusted based on the relationship between the discharge time and the preset time threshold. Among them, the preset time threshold is the longest allowable discharge time under the initial current. Usually, this time threshold is derived from the statistical analysis of the starting current requirements of a large number of cars, representing the upper limit of the time required for most car models to successfully start at this initial current. If the actual discharge time exceeds this threshold, it means that the current current may not be enough to start the car, and continuing to discharge will only waste energy. Therefore, once a timeout is detected, the system will decisively terminate the discharge to reduce energy consumption.

[0067] For example, after a large number of experimental statistics, it was found that 90% of cars can be started within 3 seconds at a current of 200A. Therefore, the system sets the time threshold to 3 seconds. When using the initial current discharge, if the car has not started successfully after 3 seconds, the system will immediately stop discharging and start executing the next stage of intelligent adjustment strategy.

[0068] S103, increasing the initial starting current in sequence by a preset current increment to obtain one or more incremental starting currents.

[0069] When the system detects that the vehicle cannot be successfully started within the specified time using the initial current, it will automatically start adjusting the starting current to find the most suitable current value. Specifically, the system controls the vehicle emergency starting power supply to gradually increase the current by a fixed current increment based on the initial current until the vehicle starts successfully or reaches the current upper limit.

[0070] It should be noted that the current increment is a fixed value set in advance, which determines the amplitude of each current adjustment. The selection of the increment needs to comprehensively consider the starting efficiency and the power supply load. It is necessary to minimize the number of adjustments as much as possible to speed up the starting speed, and at the same time avoid the current exceeding the safe range due to too large an increment.

[0071] For example, the initial starting current of a certain emergency power supply is 200A, and the selected current increment is 50A. When the initial current fails to start the vehicle, the system will successively try incremental currents such as 250A, 300A, 350A, etc. until the vehicle is finally started successfully. The system may obtain one or more incremental starting current values during the whole process, providing multiple options for determining the optimal starting current later.

[0072] S104. Discharge successively using the incremental starting current, and detect whether the vehicle starts successfully under each incremental starting current.

[0073] After determining a series of incremental starting currents, the system will control the vehicle emergency starting power supply to successively use the determined incremental starting current values for starting attempts. Specifically, the system successively selects an incremental starting current from small to large to discharge the vehicle battery, and detects whether the vehicle starts successfully within the preset time threshold corresponding to the incremental starting current value.

[0074] For example, for a certain vehicle that is difficult to start, the system obtains three incremental current alternative values of 250A, 300A, and 350A through step S103. Subsequently, the system successively uses these three currents for starting attempts. If the vehicle does not start successfully within the preset time threshold corresponding to the 250A current, the incremental current value is adjusted to 300A. If the vehicle starts successfully when using the 300A current, there is no need to continue trying larger currents. The system will mark 300A as the optimal current for this start and stop the subsequent start detection.

[0075] S105. If the vehicle starts successfully under the current incremental current and discharge duration, stop increasing the initial starting current, and record the current incremental starting current and discharge duration.

[0076] When the system detects through step S104 that a certain incremental starting current can successfully start the vehicle, the current starting detection process can be terminated. At this time, the system has found a relatively optimal starting current value and there is no need to try larger currents.

[0077] Therefore, the system will immediately stop the incremental discharge, and save the currently used incremental starting current value and the corresponding discharge duration as the optimal starting parameters for optimizing the subsequent starting strategy.

[0078] For example, for a certain vehicle, the system determines through preliminary detection that an incremental current of 300A can start stably, and the discharge duration is 2.5 seconds. At this time, the system stops increasing the current and records these two key parameters, 300A and 2.5 seconds, in the database as the optimal starting reference values for this vehicle model. In the subsequent restart of this vehicle, the system can directly adopt this set of parameters without re-detection, thus significantly improving the starting efficiency.

[0079] S106: If the vehicle fails to start successfully at the current incremental current and discharge duration, continue to use the next incremental starting current to detect whether the vehicle starts successfully.

[0080] Specifically, the system can obtain one or more incremental currents arranged in ascending order after step S103. When the system detects through step S104 that the vehicle cannot start within the discharge duration corresponding to the current incremental starting current, it controls the emergency starting power supply of the vehicle to increase the current to the magnitude of the next incremental current, and then detects again whether the vehicle starts successfully. If it is detected that the vehicle starts successfully at the next incremental current, it enters step S105. On the contrary, if it is detected that the vehicle does not start successfully at the next incremental current, continue to execute step S106, and select the next one from the incremental currents arranged in ascending order for starting detection.

[0081] S107: Stop discharging when it is detected that the incremental starting current exceeds the preset current threshold, and issue a fault warning.

[0082] Although the system can effectively meet the starting requirements of the vast majority of vehicles through the adaptive adjustment of the starting current, in actual operation, some extreme situations may be encountered, such as vehicle failures, line failures, etc., resulting in the inability to complete the starting no matter how much the current is increased. For such abnormal situations, the system presets a maximum allowable current threshold as the upper limit value for the starting current adjustment. When it is detected that the incremental current exceeds this threshold, the system will immediately determine it as a serious fault, abort the subsequent starting attempts, and send a warning message to the user.

[0083] For example, the rated current of a certain emergency starting power supply is 600A. Considering a certain margin, the system sets the maximum current threshold to 550A. During the detection process in step S104, if the vehicle still cannot be started after using an incremental current of 500A, and the next incremental current is 550A, which has reached the threshold. At this time, the system will immediately abort the discharge and issue a warning, prompting the user that there may be a vehicle or circuit fault, and it is recommended to check the fault first before attempting to start again to avoid blindly increasing the current and causing damage or safety issues.

[0084] It should be noted that the setting of the above preset current threshold needs to comprehensively consider factors such as the actual output capacity of the vehicle emergency power supply, battery safety parameters, and the current-carrying capacity of the connecting cables to ensure safe use. The specific threshold parameters are determined according to the actual situation and are not limited here.

[0085] Through the above embodiments, after detecting the start command, the system first discharges using the initial start current and records the discharge duration. When the discharge duration exceeds the threshold, the discharge stops; otherwise, the start current is increased in sequence with a preset increment until the vehicle starts successfully or the current exceeds the threshold. By adaptively adjusting the start current and discharge duration, the system can automatically provide an appropriate start current according to the actual start requirements of different vehicles, achieving energy conservation while ensuring the start success rate. For vehicles that are easy to start, waste of current and duration can be avoided; for vehicles that are difficult to start, the start requirements can be met by increasing the current and extending the time, thus significantly improving the practicality and energy utilization efficiency of the vehicle emergency starting power supply, saving electrical energy and increasing the vehicle start success rate.

[0086] Next, a further and more specific process description of the method provided in this embodiment will be given. Please refer to Figure 2 , which is another process schematic diagram of an automatic energy-saving control method for a vehicle emergency starting power supply in an embodiment of the present application.

[0087] S201. Monitor the start data during the engine start process within a preset time period.

[0088] During the actual use of the vehicle emergency starting power supply, multiple sensors such as a voltage sensor, a current sensor, and a rotation speed sensor can be configured on the vehicle emergency starting power supply for data collection. The system will collect and analyze key parameters such as voltage, current, and rotation speed during the normal start process of the vehicle through the above sensors. Specifically, the system will select a suitable monitoring time period and record the whole process data of multiple start processes of the vehicle within this time period. The monitored parameters mainly include the battery voltage change curve, start current change curve, engine rotation speed change curve, etc. during the start process.

[0089] For example, the system can choose to continuously monitor the vehicle startup process 10 times. Each time it starts up, with a sampling period of 50 ms, it records the real-time values of voltage, current, and rotational speed during the entire process from ignition start to engine speed stabilization. After accumulating 10 times, the system can obtain a quite complete engine startup dataset.

[0090] S202. Construct a startup model based on the startup data.

[0091] After the system obtains a certain amount of startup data, it will preprocess the startup data to obtain a startup data training set. Then, it uses the startup data training set to train the startup model. Through data mining and machine learning algorithms, it extracts features from the time-series data in the startup data training set, quantitatively describes the dynamic change laws of parameters such as voltage, current, and rotational speed during the startup process. So that the startup model can predict the current demand range based on the current real-time startup data.

[0092] S203. Predict the demand current range and the value of the initial startup current based on the real-time startup data and the startup model.

[0093] Specifically, when the automotive emergency startup power supply receives a startup instruction, the system will retrieve the historical startup data of the vehicle from the memory according to the connected vehicle model information, etc., generate a corresponding startup model based on the historical startup data. Then, the system will use the real-time data collected at the vehicle end, including the current battery voltage, ambient temperature, etc., as input parameters and input them into the startup model to calculate and output the optimal startup current range. The optimal startup current range refers to an interval of the current required for the vehicle to start normally, and the upper and lower limits correspond to the maximum current demand and the minimum current demand respectively, and set the lower limit value of the optimal startup current range as the value of the initial startup current.

[0094] For example, the system detects that the current vehicle battery voltage is 11.5 V and the ambient temperature is -5 °C. Combining the historical startup data of this vehicle model and substituting it into the existing startup model, it can calculate that the optimal startup current range under the current working conditions is 220 A - 280 A. The system generates a startup current recommendation value interval based on this, but it does not simply take the median value of the interval. Instead, it first tries to start with the lower limit of the interval, 220 A, and gradually increases to the upper limit of 280 A when 220 A cannot meet the requirement, realizing the dynamic optimization of the startup current through this progressive adjustment.

[0095] The system monitors the engine startup data over a period of time, such as voltage, current, rotational speed, etc., and constructs a startup model based on this data to predict in real time the current range required for the current vehicle startup. Taking the lower limit of this range as the initial startup current can make the startup current closer to the actual needs of the vehicle from the very beginning, further improving the startup efficiency and success rate, making the startup process more intelligent, and the effects in terms of energy conservation and speed increase will be more significant.

[0096] S204. Display the initial startup current and the status information of the automotive emergency startup power supply through the display.

[0097] Intelligent emergency startup control should not only achieve the adaptive adjustment of the startup current, but also have good human-computer interaction, enabling users to intuitively understand the working state of the device and the key parameters of the startup process. Specifically, the system feeds back information such as the initial startup current and the device status to the user in real time through the display interface carried by the automotive emergency startup power supply, improving the user experience while also providing necessary supervision means for the user.

[0098] S205. Automatically connect to the vehicle battery for charging when it is detected that the power of the automotive emergency startup power supply is lower than the preset power threshold.

[0099] Specifically, the system will set a power threshold for the automotive emergency startup power supply and monitor the power information of the automotive emergency startup power supply in real time. When it is detected that the power status in this power information is lower than the preset power threshold, a warning reminder will be given. This warning reminder can be in the form of text or voice prompts through the display on the power supply, or by sending a text message reminder to the user's terminal device, which is not limited here. In addition, if it is detected that the automotive emergency startup power supply is already connected to the vehicle battery, then turn on the power switch between it and the vehicle battery to supplement the power through the vehicle battery.

[0100] The system automatically detects the power of the emergency startup power supply and actively connects to the on-vehicle battery for charging when its power is lower than the preset threshold, which can ensure that the emergency power supply is always in a full-power state or the best state, ready to perform emergency startup for the vehicle at any time, greatly improving the reliability and real-time availability of the startup power supply, which is particularly important for vehicle owners who travel frequently and have high requirements for backup power supplies.

[0101] S206. Integrate a voice recognition system and translate the recognized voice commands of the user to obtain current setting information.

[0102] Specifically, the system will have a built-in speech recognition engine that can collect the user's voice commands in real time through a sound pickup hardware, and use acoustic models and language models for parsing and understanding. The user can directly use spoken language to control the starting current. For example, "Set the starting current to 300 amperes" or "Adjust the charging time to 3 seconds". Through semantic analysis algorithms, the system can accurately extract the key numerical information in the command and directly apply it to the adjustment of the starting current, thus providing the user with a more natural and efficient control method.

[0103] The system introduces a human-computer interaction function, using speech recognition technology, enabling the user to control the starting parameters through voice commands, further enhancing the convenience of user operation.

[0104] S207. Perform emergency power supply to the vehicle according to the received current setting information input by the user.

[0105] Although the vehicle emergency starting power supply can automatically adjust the optimal starting current through intelligent control, it is also very necessary to grant the user a certain degree of manual control in some special cases. Therefore, the system can receive the size and duration of the user-defined starting current through a preset interface to receive data or wireless data transmitted by the user terminal device, facilitating emergency power supply to the vehicle in special situations.

[0106] Specifically, the system will set an input box for current setting on the display interface, allowing the user to directly input the desired current size and power supply time through physical buttons or touch screens. For example, the user can specify: output a current of 250A for 2.5 seconds. After receiving this command, the system will automatically adjust the original starting control strategy and strictly perform the starting output according to the values set by the user until the power is automatically cut off after reaching the specified time.

[0107] The system introduces a human-computer interaction function, which can display information such as starting current settings and power supply status in real time through a display, and supports the user to manually adjust the current size and power supply duration, giving the user more right to know and control. The user can flexibly adjust according to their own experience and the current situation. Especially for the starting of some special vehicle models or in extreme environments, this manual intervention is particularly important, further improving the applicability of the vehicle emergency starting power supply.

[0108] S208. Monitor the battery temperature of the vehicle emergency starting power supply through a built-in temperature sensor.

[0109] Specifically, the system will reasonably arrange a group of temperature sensors around the battery pack of the automotive emergency starting power supply, and collect the temperature data of each area in real time through the sensors. Considering that the internal temperature distribution of the battery pack may be uneven, the system will select a multi-point temperature measurement scheme to monitor the surface temperature and internal temperature of the battery by zoning, and use the highest temperature as the representative value of the battery temperature. After the temperature signal is converted by ADC and digitally filtered, it is transmitted to the controller in a standardized data format to realize the real-time monitoring of the battery temperature of the automotive emergency starting power supply.

[0110] S209. Disconnect the current after detecting that the battery temperature exceeds the preset safety threshold, and send a warning message to the display or user terminal.

[0111] Specifically, the system will preset a temperature safety threshold as the trigger condition for starting the protection mechanism. The setting of this threshold needs to comprehensively consider various factors such as battery material characteristics, environmental factors, and usage intensity, which are not limited here. When it is detected that the battery temperature continuously exceeds the safety threshold for a certain period of time (such as 5 s), the system will immediately start the power-off protection, quickly cut off the charge and discharge circuit by cutting off the relay or controlling the MOS transistor, block the heating of the battery by the external large current, and avoid further deterioration of the temperature. At the same time, the system will also send warning signals to the user through various means such as buzzers, indicator lights, and displays, indicating that the current battery is in an over-temperature state. If the device is connected to the cloud service, the warning will also be reported to the cloud synchronously and pushed to the user through the App, reminding them to stop using it in time and start it again after the battery cools down.

[0112] During the startup process, the system monitors the battery temperature of the emergency power supply in real time through the built-in temperature sensor. Once the temperature exceeds the safety threshold, the current will be immediately disconnected and a warning will be issued. This overheat protection mechanism can effectively avoid the out-of-control battery temperature caused by excessive startup current, prevent the battery from aging, bulging, etc. due to high temperature, which threatens the use safety and life. Especially for some large-displacement or high-power vehicle models, the instantaneous current load during startup is relatively large, which is more likely to cause battery heating problems, thereby improving the use safety of the automotive emergency starting power supply.

[0113] The following is a further and more specific process description of the method provided in this embodiment. Please refer to Figure 3 , which is a schematic flowchart of the system determining the initial startup current when the automotive emergency starting power supply reconnects to the vehicle in the embodiment of the present application.

[0114] S301. Obtain and record the current first vehicle information connected.

[0115] After the system detects that the emergency starting power supply for vehicles is connected to a vehicle, it reads the identity information of the currently connected vehicle. Specifically, the system can read the vehicle identification number (VIN) information as the displacement identifier of the vehicle by connecting to the On-Board Diagnostics (OBD-II, second generation) port of the vehicle, or obtain the vehicle information through a dedicated interface, which is not limited here.

[0116] S302. After connecting to the vehicle next time and detecting a start instruction, obtain second vehicle information.

[0117] After detecting that the emergency starting power supply for vehicles has been disconnected from the vehicle, when it is detected again that the emergency starting power supply for vehicles establishes a connection with the vehicle, the vehicle information is read again to obtain second vehicle information. The system compares the second vehicle information with the first vehicle information stored in the database to determine whether the currently connected vehicle is the vehicle that has been connected before.

[0118] S303. If the second vehicle information is the same as the first vehicle information, set the incremental starting current to the new initial starting current.

[0119] Specifically, when the system detects that the second vehicle information is the same as the first vehicle information, it determines whether the currently connected vehicle is the vehicle that has been connected before. Therefore, directly set the incremental starting current corresponding to the first vehicle as the initial starting current of the currently connected vehicle.

[0120] For repeated starting of the same vehicle by the system, after the first successful start, the optimal starting current and vehicle information at that time are recorded. When connecting to the same vehicle next time, directly set the previous optimal current as the new initial starting current. This enables the emergency starting power supply to continuously accumulate and precipitate the best starting parameters for each vehicle model, and improves the starting efficiency and accuracy with the increase in the number of uses.
