Description

Technical Field

[0001] The present application relates to the field of model calculation technology, and in particular to a method for heating an emergency starting power supply for an automobile with ultra-low temperature discharge and related equipment. Background Art

[0002] With the continuous advancement of automobile technology, drivers have higher and higher requirements for automobile safety and comfort. In order to cope with the sudden failure of the main power emergency starting power supply, many car owners will have an emergency starting power supply in the car. The emergency starting power supply can provide the necessary power after the main power emergency starting power supply of the car fails, preventing the driver from falling into a completely incompetent state. However, in a low temperature environment, the power supply current of ordinary lead-acid batteries will be reduced, resulting in insufficient starting current, so the emergency starting power supply has a serious risk of emergency starting power failure.

[0003] In the related art, a heating module can be added to the emergency starting power supply to heat the emergency starting power supply at a low temperature so as to maintain the emergency starting function of the emergency starting power supply.

[0004] However, if the emergency starting power supply is continuously heated, it may cause a large amount of power loss in the emergency starting power supply itself, and may also affect the emergency starting function of the emergency starting power supply. Summary of the invention

[0005] The present application provides a method and related equipment for heating an emergency starting power supply for an automobile with ultra-low temperature discharge, which is used to obtain current vehicle data, battery data, environmental data and usage mode data, input a probability prediction model to evaluate the starting probability, and then calculate the target temperature according to the ambient temperature trend and the normal battery operating temperature. Finally, a heating strategy is formulated according to the power status. This method can realize accurate temperature prediction and intelligent heating control of the emergency starting power supply in a low-temperature environment. This is different from simple heating in related technologies and can greatly reduce unnecessary energy consumption. This method realizes accurate and efficient heating of the emergency power supply in a low-temperature environment, effectively reduces the impact of heating on power, and ensures the availability of the emergency starting function.

[0006] In a first aspect, the present application provides a method for heating an ultra-low temperature discharge automobile emergency starting power supply, which is applied to an emergency starting power supply, and the method comprises: Obtain vehicle data, battery data, environmental data of the current environment, and usage mode data of the emergency starting power supply of the vehicle; Inputting the vehicle data, the battery data, the environment data and the usage mode data into a probability prediction model to obtain a starting probability of using the emergency starting power supply of the automobile within a preset time period; When the startup probability is greater than a preset startup threshold, obtaining future temperature data at a preset time point; If the future temperature data is lower than the preset temperature threshold, the ambient temperature change trend within the preset time period is obtained, and the preset time period is the time range from the current time point to the preset time point, and the preset time period includes at least one preset heating time period; Calculate a target temperature set in each preset heating time period according to the real-time ambient temperature and the normal battery operating temperature, wherein the target temperature set includes a target temperature for each preset heating time period, and the target temperature is the difference between the real-time ambient temperature and the normal battery operating temperature; Determine the emergency power supply heating strategy according to the current power of the emergency starting power supply of the vehicle and the target temperature set; A heating instruction is generated according to the emergency power supply heating strategy and sent to a heating module, so that the heating module heats the emergency starting power supply of the vehicle.

[0007] In the above embodiment, by acquiring the current vehicle data, battery data, environmental data and usage mode data, inputting the probability prediction model to evaluate the startup probability, and then calculating the target temperature according to the ambient temperature trend and the normal battery operating temperature, and finally formulating a heating strategy according to the power status, accurate temperature prediction and intelligent heating control of the emergency starting power supply in a low-temperature environment can be achieved, which can greatly reduce unnecessary energy consumption. This method realizes accurate and efficient heating of the emergency power supply in a low-temperature environment, effectively reduces the impact of heating on power, and ensures the availability of the emergency starting function.

[0008] In combination with some embodiments of the first aspect, in some embodiments, the step of determining the emergency power supply heating strategy according to the current power of the automobile emergency starting power supply and the target temperature set specifically includes: In the case where the current power is not less than the preset power, if there is a target temperature in the current preset heating time period that is greater than the preset temperature threshold, the current heating power set of each current preset heating time period is calculated according to the current temperature and the first-stage target temperature, and the first-stage target temperature is the target temperature corresponding to the first time period in multiple preset heating time periods; Heating the vehicle emergency starting power supply in each current preset heating time period according to all current heating powers in the current heating power collection; If there are other preset heating time stages in which the target temperature is not greater than the preset temperature threshold, the first heating power is used to heat the emergency starting power supply of the vehicle, and the other preset heating time periods are time periods in all preset heating time periods except the current preset heating time period, and all preset heating time periods are all preheating time periods within the time range from the current time point to the preset time point.

[0009] In the above embodiment, when the battery is fully charged, the precise heating power required for each heating period is calculated based on the difference between the ambient temperature and the target temperature, and the battery pack is heated in a targeted manner in different time periods according to the calculated heating power. The battery can be heated in precise segments, which can not only make the temperature in each time period reach the optimal working state, but also avoid excessive power loss.

[0010] In combination with some embodiments of the first aspect, in some embodiments, the step of generating a heating instruction according to the emergency power supply heating strategy and sending it to a heating module so that the heating module heats the emergency starting power supply of the vehicle specifically includes: In the case where the current power of the automobile emergency starting power supply is lower than the preset power, if there is a target temperature in the first heating time period that is greater than the preset temperature threshold, the second heating power is used to heat the key area, the key area is the core working part of the automobile emergency starting power supply, and the first heating time period is the time period in which the heating measure is actually taken when the automobile emergency starting power supply is heated; When the current power of the automobile emergency starting power supply is lower than the preset power, the third heating power is used to heat the non-critical area, and the third heating power is less than the first heating power. The non-critical area is a non-core working component of the automobile emergency starting power supply.

[0011] In the above embodiment, by setting multiple alternative power levels to provide sufficient heating when power is sufficient, and only heating key components when power is insufficient, and reducing heating of non-critical areas, refined optimization control of the heating strategy can be achieved. Unlike the problems of power waste or inability to provide targeted heating in the prior art, this multi-level heating method can maximize the use time of the emergency power supply and improve reliability while ensuring the heating of key components.

[0012] In combination with some embodiments of the first aspect, in some embodiments, after the step of generating a heating instruction according to the emergency power supply heating strategy and sending the instruction to the heating module so that the heating module heats the emergency starting power supply for the vehicle, the method further includes: Get the current speed, acceleration and bumpiness of the car; Identifying a driving mode of the current vehicle according to the driving speed, the acceleration and the degree of bumpiness, wherein the driving mode includes a congestion mode, a high-speed mode and a waiting mode; The current heating strategy in the emergency starting power supply of the vehicle is adjusted according to the driving mode.

[0013] In the above embodiment, after the heating control, the driving speed, acceleration and degree of turbulence of the car will be obtained in real time, and the current driving mode of the vehicle, such as congestion mode, high-speed mode and waiting mode, will be identified based on these data, and then the heating strategy in the emergency starting power supply will be optimized and adjusted in real time. This method that can dynamically identify the driving mode and adjust the heating strategy can achieve more refined and intelligent control, such as using lower power heating in congestion and waiting modes, and accurately heating key components at high speeds, which can not only ensure the normal operation of the power supply, but also greatly save power loss. Compared with the fixed heating mode of the prior art, this solution realizes the dynamic optimization of the heating strategy and significantly improves energy efficiency.

[0014] In combination with some embodiments of the first aspect, in some embodiments, the step of adjusting the current heating strategy in the emergency starting power supply of the vehicle according to the driving mode specifically includes: If the current vehicle is in the congestion mode, the current heating power is calculated according to the optimal working temperature of the emergency starting power supply of the vehicle and the current ambient temperature, and the emergency starting power supply of the vehicle is heated according to the current heating power; If the current vehicle is in the high-speed mode, heating the key area of ​​the emergency starting power supply of the vehicle according to the second heating power; If the current vehicle is in the waiting mode, the emergency starting power supply of the vehicle is heated according to the second heating power.

[0015] In the above embodiments, the optimization methods of heating strategies under different driving modes are specifically given. The current appropriate heating power is calculated in congestion and waiting modes, and key components are heated in high-speed mode to save power. These specific optimization strategies can make the heating more suitable for actual driving conditions and give full play to the energy-saving effect. Unlike the heating modes in the prior art that cannot distinguish different usage scenarios, this technical solution realizes refined scene recognition and corresponding strategies, which can significantly reduce power waste and extend the available time of emergency power supply.

[0016] In combination with some embodiments of the first aspect, in some embodiments, after the step of sending a heating instruction to the heating module according to the emergency power supply heating strategy so that the heating module heats the emergency starting power supply for the vehicle, the method further includes: Receive a preheating operation instruction sent by a client, the preheating operation instruction including a preheating time and a preheating temperature; A heating instruction is generated according to the preheating time and the preheating temperature. The heating instruction includes the heating module heating the emergency power supply to the preheating temperature according to the preheating power. The preheating power is calculated by the preheating time, the preheating temperature and the current battery temperature.

[0017] In the above embodiment, by enabling the emergency starting power supply to receive remote preheating control instructions from the client, user-customized heating can be achieved. The user can set the preheating time and target temperature in advance according to the actual travel plan. By automatically calculating the required heating power and executing the corresponding heating control, the user experience and intelligence level of the emergency starting power supply can be significantly improved.

[0018] In combination with some embodiments of the first aspect, in some embodiments, after the step of generating a heating instruction according to the preheating time and preheating temperature, wherein the heating instruction includes the step of the heating module heating the emergency power supply to the preheating temperature according to the preheating power, wherein the preheating power is calculated from the preheating time, the preheating temperature and the current battery temperature, the method includes: If the current battery power of the automobile emergency starting power supply is lower than the minimum power threshold, a prompt message is issued, and the prompt message is used to prompt the user to charge the automobile emergency starting power supply.

[0019] In the above embodiment, after executing the preheating control, it will also monitor whether the remaining power of the emergency starting power supply is lower than the minimum power threshold. When it is detected that the power is too low, a charging reminder message will be actively issued. This power warning reminder can avoid the user being interrupted by a sudden shutdown when the power is exhausted, and let the user realize in advance that the battery needs to be charged in time.

DETAILED DESCRIPTION

[0028] 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 of the present application, the singular expressions "one", "a kind of", "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 of the listed items.

[0029] 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.

[0030] For ease of understanding, the application scenarios of the embodiments of the present application are introduced below: With the rapid development of automotive electronic technology, the use of various on-board electronic devices has become increasingly widespread, and the dependence on the automotive power system has greatly increased. If the main power system suddenly fails while driving, it will directly threaten driving safety. To solve this problem, more and more car companies have begun to configure emergency starting power supply systems on their vehicles to temporarily supply power to some key electrical equipment after the main power fails. However, in cold weather, the low-temperature power attenuation problem of ordinary lead-acid batteries will seriously restrict the starting ability of the emergency power supply. If the emergency power supply cannot temporarily guarantee the power supply of key electrical equipment due to poor starting at low temperatures, the driver will face a very dangerous situation. Therefore, a new emergency starting power supply technology solution that can detect ambient temperature and intelligently manage battery heating is needed to ensure normal operation in low-temperature environments.

[0031] In response to the low-temperature performance problem of ordinary batteries, some car companies use lithium batteries with better performance as emergency power sources. However, lithium batteries are expensive and the cost of large-scale use is too high. Other car companies use the strategy of continuous heating of batteries, but continuous heating consumes a lot of electricity and affects the use time. In general, the solutions in the existing technology are either too costly or consume a lot of electricity, and cannot meet the working requirements of emergency power sources at low temperatures.

[0032] The present application provides a method for heating an emergency starting power supply for an automobile with ultra-low temperature discharge. The method can detect the ambient temperature, predict the probability of starting, calculate the heating target temperature, and determine the heating strategy. For example, if it is predicted that starting may be required in 2 hours and the temperature will be lower than -10°C, the heating target temperature for each period in the next 2 hours will be calculated. If the power is sufficient, heating will be performed according to the target temperature; if the power is insufficient, only key components will be heated. The strategy can also be adjusted according to the driving status. The method realizes intelligent and refined temperature control management, which not only ensures low-temperature starting, but also saves energy consumption.

[0033] For ease of understanding, the following is a description of the process of the method provided by this implementation. Figure 1 , which is a flow chart of a method for heating an automobile emergency starting power supply with ultra-low temperature discharge in an embodiment of the present application.

[0034] S101, obtaining vehicle data of the current vehicle, starting battery data, environmental data of the current environment, and usage mode data of the emergency starting power supply of the vehicle.

[0035] Among them, vehicle data refers to data such as the car's driving speed and fuel consumption; battery data refers to usage data of the current car's starting battery, such as voltage, power, temperature and other usage parameters; environmental data refers to ambient temperature data; and usage mode data refers to the activation record of the emergency starting power supply.

[0036] Specifically, in order to predict the required emergency starting power supply heating, it is necessary to collect the current operating status of the vehicle and the usage status data of the emergency starting power supply, including obtaining the vehicle operating data such as the current driving speed and fuel consumption through the vehicle's relevant sensors, obtaining its operating voltage, power, temperature and other usage parameters from the current vehicle's starting battery, obtaining the current ambient temperature, humidity and other environmental parameters from environmental monitoring equipment, and extracting usage mode data such as the number of times the power supply is enabled from the emergency starting power supply usage log.

[0037] In some embodiments, vehicle operation data can be obtained through the car's CAN bus; the battery management emergency starting power supply is used to collect starting battery parameters, and the weather station equipment is connected to monitor environmental information; the database usage log is analyzed to extract emergency power mode data, and optionally, the vehicle data can be collected using additional sensors of the car; the starting battery is made to report status data regularly, and environmental information is retrieved using online weather forecasts; and the power activation rules are analyzed through data mining.

[0038] S102, inputting the vehicle data, the battery data, the environment data and the usage mode data into a probability prediction model to obtain a startup probability of using the emergency starting power supply of the automobile within a preset time period.

[0039] Among them, the probability prediction model can predict the probability of using the emergency starting power supply based on the input data. The starting probability refers to the possibility of using the emergency starting power supply at a given future moment. This step is to calculate the probability of obtaining the starting power supply through the prediction model.

[0040] Specifically, the emergency starting power supply inputs the collected car data, battery data, environmental data, and usage mode data into a pre-trained probability prediction model. The prediction model can integrate various influencing factors to evaluate the probability of whether the emergency starting power supply may need to be activated at a given future time point, that is, the activation probability. For example, when the ambient temperature is too low, the activation probability will increase. Calculating the accurate startup probability can provide a basis for subsequent preheating decisions.

[0041] The construction process of the probability prediction model is as follows: First, it is necessary to collect vehicle data, battery data, environmental data and usage mode data. Vehicle data includes vehicle speed and fuel consumption. Battery data includes voltage, power, and battery temperature. Environmental data includes ambient temperature and humidity. Usage mode data includes the number of times and time the emergency starting power supply is enabled.

[0042] Examples of data collection are: vehicle data, obtained through the vehicle's CAN bus, vehicle speed is 60 km / h, fuel consumption is 8 liters / 100 kilometers, battery data, battery voltage is 12.5 volts, remaining power is 80%, battery temperature is 15 degrees Celsius, environmental data, ambient temperature is 5 degrees Celsius, humidity is 60%, usage mode data: the emergency starting power supply has been activated twice in the past 24 hours.

[0043] Input data: vehicle data: [vehicle speed, fuel consumption], battery data: [voltage, power, temperature], environmental data: [temperature, humidity], usage mode data: [number of activations, activation duration]; output data: prediction result: activation probability, ranging from 0 to 1.

[0044] Training data: 20,000 emergency power supply activation records are collected within one year as training data. Each record contains input feature information and activation mark. The data is divided into training data set and validation data set in proportion; data preprocessing, normalization processing: normalize input features of different dimensions such as temperature, speed, voltage, etc., missing value processing: supplement reasonable values ​​for missing data or directly eliminate them, encoding processing: one-hot encoding of categorical data such as vehicle speed range, use PyTorch to build a model framework, define a multi-layer fully connected neural network, including an input layer, 2 hidden layers and an output layer, the hidden layer uses the ReLU activation function, the output layer uses the Sigmoid activation function to obtain probability output, the loss function uses the cross entropy loss function, and the optimizer uses the Adam algorithm. The processed data is sent to the model for training, the loss function is optimized, the parameters are updated, the effect is evaluated on the validation set, the model structure and hyperparameters are adjusted, and the performance is evaluated on an independent test set, such as the AUC curve, to examine the importance of features and conduct in-depth analysis of the model.

[0045] S103. If the future temperature data is lower than a preset temperature threshold, obtain the ambient temperature change trend within a preset time period, where the preset time period is a time range from the current time point to the preset time point, and the preset time period includes at least one preset heating time period.

[0046] Among them, the future temperature data is the predicted temperature at a preset time point; the preset temperature threshold is the temperature standard for determining whether heating is needed; the ambient temperature change trend is the pattern of temperature change over time in the future; the preset time period is the time range that needs to be considered in the future; and the preset heating time period is the time interval in which heating may be performed.

[0047] Specifically, if the future temperature data at a given preset time point obtained from the prediction model is lower than the minimum temperature threshold required for the emergency starting power supply to work normally, it is necessary to additionally obtain the change trend information of the ambient temperature in a time period from the current time point to the preset time point. The preset time period may include one or more preset heating time periods for possible preheating. The temperature change trend is obtained in order to calculate the target temperature to be achieved in each possible heating time period.

[0048] In some embodiments, temperature curve data for the next week can be obtained from the weather station; the temperature distribution for the next month can be calculated using a temperature prediction model. Optionally, an environmental sensor can be used to regularly detect the real-time temperature; and an approximate value of the future temperature can be obtained through data correction. It is understandable that the environmental temperature change trend information within a specific preset time range can also be obtained by other means.

[0049] S104. Calculate a target temperature set in each preset heating time period according to the ambient temperature change trend and the normal battery operating temperature. The target temperature set includes a target temperature for each preset heating time period. The target temperature is the difference between the real-time ambient temperature and the normal battery operating temperature.

[0050] Among them, the normal battery operating temperature is the optimal operating temperature of the emergency starting power battery; the target temperature is the temperature that the battery needs to be raised to; the target temperature collection includes target temperature values ​​corresponding to multiple time periods. This step is to calculate the target temperature that needs to be reached in each possible heating time period.

[0051] Specifically, the emergency starting power supply can calculate the target temperature to which the battery temperature needs to be raised in order to make the battery work in the best state in each possible preset heating time period based on the future change trend of the acquired ambient temperature and the normal battery temperature required for the emergency starting power supply to work. The target temperature can be obtained by calculating the difference between the current ambient temperature and the optimal working temperature. Repeating this calculation can obtain a set of target temperatures corresponding to multiple heating time periods.

[0052] In some embodiments, the target temperature can be calculated by the temperature difference method; the target value can be obtained by the temperature threshold mapping method. Optionally, the target temperature can also be predicted by a machine learning model; the influence of ambient temperature fluctuations can be eliminated by a sliding average algorithm. It is understandable that the emergency starting power supply can also calculate the target temperature information required for each heating time period by other means.

[0053] S105: determining an emergency power supply heating strategy according to the current power of the emergency starting power supply of the vehicle and the target temperature set.

[0054] Among them, the current power is the current remaining power of the emergency starting power supply; the target temperature set is the target temperature to be reached in each preset heating time period; the emergency power supply heating strategy is a heating plan formulated based on the power and target temperature. This step determines the heating strategy based on the current power and target temperature.

[0055] In some embodiments, when the current power level is not lower than the preset power level, if the target temperature within the current preset heating time period is greater than the preset temperature threshold, the current heating power set for each current preset heating time period is calculated based on the current temperature and the first stage target temperature.

[0056] S106: Generate a heating instruction according to the emergency power supply heating strategy and send it to a heating module, so that the heating module heats the emergency starting power supply of the vehicle.

[0057] The heating instruction is a control execution signal output according to the heating strategy; the heating module is a component that performs physical heating in the emergency start power supply. This step is to generate a heating control instruction and send it to the heating module to start heating.

[0058] Specifically, after determining the heating strategy of the emergency starting power supply, the emergency starting power supply needs to generate matching specific heating control instructions to control the operation of the heating module. These control instructions will include parameters such as heating start time, heating equipment selection, and heating intensity. The emergency starting power supply sends these heating instructions to the dedicated heating module through the network inside the emergency starting power supply. After receiving the instructions, the heating module will start to physically heat the battery according to the time and intensity required by the instructions.

[0059] In some embodiments, the XML format of the heating instruction can be designed, and the instruction information can be encapsulated using JSON encoding. Optionally, the instruction parameters can also be issued through a database, and the instruction can be issued using a network API. It is understandable that the emergency starting power supply can also generate instructions in other ways and issue them to the heating module to start heating the emergency starting power supply.

[0060] After combining the above scenarios, the following is a more detailed description of the process of the method provided by this implementation. Figure 2 , is another flow chart of the method for heating the emergency starting power supply of an automobile with ultra-low temperature discharge in an embodiment of the present application.

[0061] S201, determining an emergency power supply heating strategy according to the current power of the vehicle emergency starting power supply and the target temperature set.

[0062] It can be understood that this step is similar to step S105 and will not be described in detail here.

[0063] S202. When the current power level is not lower than the preset power level, if the target temperature in the current preset heating time period is greater than the preset temperature threshold, the current heating power set of each current preset heating time period is calculated based on the current temperature and the first-stage target temperature, and the first-stage target temperature is the target temperature corresponding to the first time period in multiple preset heating time periods.

[0064] Among them, the preset power is the threshold for judging whether the power is sufficient, the current temperature is the real-time temperature of the emergency starting power supply environment; the target temperature is the temperature that needs to be reached. This step is to calculate the heating power of each time period under the condition that the emergency starting power supply has sufficient power.

[0065] Specifically, if the emergency starting power supply detects that the current remaining power is higher than the preset minimum power threshold for judging that it is sufficient, it will obtain the current ambient temperature, for example, 5°C, and then find a period in which the target temperature is greater than the preset temperature threshold in multiple heating periods, for example, the target temperature of the first period is 15°C. The emergency starting power supply will calculate the temperature difference of 10°C between the current temperature of 5°C and the target temperature of 15°C in the first period, and calculate the heating power required for the first period based on the thermodynamic model. Repeating this calculation can obtain the heating power required for each period, forming a current heating power collection.

[0066] In some embodiments, the heating power can be calculated by the temperature difference, and the power can be obtained by using a thermodynamic model. Optionally, the heating power can be predicted by using a temperature-power curve fitting calculation and machine learning.

[0067] S203, heating the vehicle emergency starting power supply in each current preset heating time period according to all current heating powers in the current heating power set.

[0068] The heating power set includes the heating power values ​​calculated for each preset heating time period. In this step, the emergency starting power source controls each time period according to the power value in the heating power set to achieve accurate segmented heating.

[0069] Specifically, the emergency starting power supply will obtain the current heating power collection, which includes the heating power value corresponding to each preset heating period, such as 20W for the first period, 15W for the second period, etc. After the emergency starting power supply obtains this collection, it will enable the heating device for heating when entering the corresponding period. For example, when entering the first heating period, it will control the heating device to work at a power of 20W; when entering the second heating period, it will be adjusted to work at a power of 15W. By precisely controlling according to the correspondence between the time period and the power value, the emergency starting power supply can achieve the goal of precise segmented heating, which not only meets the temperature requirements of different time periods, but also improves the flexibility and controllability of heating.

[0070] In some embodiments, digital signals can be used to modulate the operating voltage and current of the heating device to achieve accurate power control; pulse width modulation can also be used to adjust the average power of the heating device; and feedback control models such as PID algorithms can be established to adjust power output according to deviations.

[0071] S204. If there are other preset heating time stages in which the target temperature is not greater than the preset temperature threshold, the first heating power is used to heat the emergency starting power supply of the vehicle, and the other preset heating time periods are time periods in all preset heating time periods except the current preset heating time period, and all preset heating time periods are all preheating time periods within the time range from the current time point to the preset time point.

[0072] The preset temperature threshold is a temperature standard for determining whether heating is required; the first heating power is a preset low power for heating. This step is to use a lower heating power during the period when the emergency starting power supply does not have a high temperature requirement.

[0073] Specifically, when the emergency starting power supply calculates the heating power for each time period, it will first determine whether the target temperature of the time period is higher than the preset temperature threshold. If the target temperature of a certain time period is not high, for example, only 5°C, which is lower than the preset threshold of 15°C, the emergency starting power supply will use the preset first low power, such as 5W, to heat the time period. This can avoid not heating at all because the target temperature of a certain time period is not high, which will cause power waste in other time periods. By adopting low-power heating, basic temperature support can be provided.

[0074] In some embodiments, the power can be reduced by adjusting the operating voltage of the heating device; the average power can be reduced by controlling the heating cycle; and low-power heating can be achieved by using a temperature-power mapping table.

[0075] S205. When the current power level of the automobile emergency starting power supply is lower than the preset power level, if the target temperature within the heating time period is greater than the preset temperature threshold, the second heating power is used to heat the key area, and the key area is the core working component of the automobile emergency starting power supply. The first heating time period is the time period in which heating measures are actually taken when the automobile emergency starting power supply is heated.

[0076] Among them, the preset power is the threshold for judging insufficient power; the second heating power is the standby low power for heating; the core working components refer to the components that play a key role in the emergency starting power supply, such as battery core packs, circuit control boards, power management modules, etc. These components are the core of the starting power supply to achieve normal power supply function. This step is that the emergency starting power supply only performs low-power heating on key components when the power is insufficient.

[0077] Specifically, if the emergency starting power supply detects that the current power data is lower than the preset low power threshold, it will re-evaluate the heating strategy for each period. For periods with high target temperatures, the emergency starting power supply will only turn on the heating of the core working parts of the corresponding battery, and use the preset second backup low power, such as 20W, to ensure that key parts work properly. This can effectively save power and extend the use time of the emergency starting power supply.

[0078] In some embodiments, only the core components can be heated by local heating technology; independent power control can also be used to power key areas. Optionally, the power allocation to key areas can also be adjusted by priority management.

[0079] In the automobile emergency starting power supply, a special power control module is provided to realize the control of the second heating power and the third heating power. The module accurately controls the power by adjusting the current in the heating circuit. For the second heating power, when it is detected that the current power is lower than the preset power and the target temperature in the first heating time period is greater than the preset temperature threshold, the power control module adjusts the current to the value corresponding to the second heating power, for example, by adjusting the conduction angle of the thyristor. For the third heating power, the module also limits the current to a lower value to achieve an output lower than the first heating power.

[0080] In terms of regional heating distribution, a zoned heating layout is adopted. Key areas, such as battery core packs, circuit control boards, etc., are arranged with independent heating elements, which are directly connected to specific output ports of the power control module to ensure that only key areas are heated when the second heating power is used. Non-critical areas, such as battery housings, cooling fans, etc., are taken care of by another group of heating elements, which are connected to other ports of the power control module. When the third heating power is used, only these non-critical areas are heated at a lower power. At the same time, the time allocation for heating different areas can be set according to actual needs. For example, when the power is tight, priority is given to ensuring that key areas are heated for a certain period of time, and then non-critical areas are heated for a short period of time.

[0081] Inside the car emergency starting power supply, there is an intelligent power distribution and control unit (IPDCU), which is specifically used to achieve precise control and reasonable distribution of the second heating power and the third heating power. The IPDCU consists of a microprocessor, a power regulation circuit, and multiple temperature sensors. When it is detected that the current power is lower than the preset power and the target temperature in the first heating time period is greater than the preset temperature threshold, the microprocessor calculates the current value required for the second heating power according to the preset algorithm. The power regulation circuit uses pulse width modulation (PWM) technology to accurately adjust the current in the heating circuit by changing the duty cycle of the pulse signal, thereby achieving the output of the second heating power. For example, when it is calculated that the second heating power of 20W needs to be output, the microprocessor calculates the corresponding current value of 1.67A based on the battery voltage (assuming it is 12V), and then adjusts the duty cycle of the PWM signal to make the average current at both ends of the heating element reach 1.67A, thereby achieving heating of key areas (such as battery core packs, circuit control boards and other core components) For the control of the third heating power, IPDCU is also based on the calculation results of the microprocessor. Since the third heating power is less than the first heating power, the microprocessor will calculate the corresponding current value according to the preset power level relationship (for example, setting the third heating power to 50% of the first heating power), and limit the current to this value through the power regulation circuit. In terms of hardware structure, independent heating elements are arranged in key areas and non-key areas (such as battery housing, cooling fan, control panel frame, wiring trough, external connection port, etc.). The heating elements in the key areas are made of high thermal conductivity materials to ensure that heat can be quickly and effectively transferred to the core components. They are directly connected to the specific power output port of IPDCU to ensure that when the second heating power is output, only the heating elements in the key areas can obtain electrical energy for heating. The heating elements in the non-key areas are made of ordinary thermal conductive materials, which are connected to another independent power output port of IPDCU. When the third heating power is output, only the non-key areas are heated at low power.

[0082] In order to achieve a reasonable allocation of heating time for different areas, IPDCU has a built-in time allocation module. When the power is lower than the preset power, the module formulates heating time strategies for different areas based on factors such as the remaining power ratio and ambient temperature. For example, when the power is 30% remaining, in a heating cycle, the critical area is first heated for 80% of the time, and then a short heating pulse is provided to the non-critical area in the remaining 20% ​​of the time to maintain its basic temperature and avoid the impact of low temperature on overall performance. At the same time, IPDCU will also monitor the temperature of each area in real time, and dynamically adjust the heating power and time allocation through the signal feedback from the temperature sensor to ensure that the heating process not only meets the working requirements of the emergency starting power supply, but also saves power to the greatest extent. S206. When the current power of the automobile emergency starting power supply is lower than the preset power, a third heating power is used to heat the non-critical area, where the third heating power is lower than the first heating power. The non-critical area is a non-core working component of the automobile emergency starting power supply.

[0083] Examples of non-core working parts include: battery casing, which is the outer packaging of the battery and is not a core component for power generation; cooling fan, which is used to cool the circuit board and is not critical to the power supply function; control panel frame: the protective frame outside the panel and is not a critical part of the control; wiring duct, which is a channel for laying wires and is not critical to the power supply function; external connection port, which is an interface for connecting to external devices and is not critical to starting the power supply function.

[0084] Specifically, if the current power level is lower than the preset power threshold, indicating that the power level is tight, the emergency starting power supply will reduce the heating intensity of non-critical areas. It will use a preset third very low heating power, such as 10W, to heat the non-critical areas of the battery, such as the outer shell, etc., which can further reduce unnecessary power consumption and leave more power for key components.

[0085] In some embodiments, low-power heating of non-critical areas can be achieved through local heating technology; independent low-power power supplies can also be used to power and heat non-critical areas, and the heating power allocation of non-critical areas can be further reduced through priority management means.

[0086] S207: Generate a heating instruction according to the emergency power supply heating strategy and send it to a heating module, so that the heating module heats the emergency starting power supply of the vehicle.

[0087] Among them, the heating instruction is an instruction for controlling the operation of the heating module, and the heating module is a device for implementing physical heating. This step is that the emergency starting power supply generates an instruction for controlling the heating module according to a determined heating strategy.

[0088] Specifically, after calculating and determining the heating strategy of the emergency starting power supply, it is necessary to generate matching specific heating control instructions and send them to the heating module. These instructions will include parameters such as heating period, heating power, and heating area. The emergency starting power supply will send these heating instructions to a dedicated heating module through the internal network. After receiving the instructions, the heating module will control the corresponding components to start heating according to the instructions to physically heat the battery pack.

[0089] After combining the above scenarios, the following is a more detailed description of the process of the method provided by this implementation. Figure 3 , is another flow chart of the method for heating the emergency starting power supply of an automobile with ultra-low temperature discharge in an embodiment of the present application.

[0090] S301. Generate a heating instruction according to the emergency power supply heating strategy and send it to a heating module, so that the heating module heats the emergency starting power supply of the vehicle.

[0091] It can be understood that this step is similar to step S105 and will not be described in detail here.

[0092] S302: Obtain the current driving speed, acceleration and degree of bumpiness of the vehicle.

[0093] Among them, the driving speed can reflect the movement state of the car; the acceleration indicates how fast the car's speed changes; and the degree of bumpiness represents the vibration and shock generated by the vehicle due to uneven road surface during driving. The purpose of this step is to obtain real-time operating data of the car during driving.

[0094] Specifically, in order to evaluate the current driving status of the car, the emergency starting power supply needs to collect the speed index, acceleration index and vibration degree of the vehicle during driving. These data can be obtained through the sensor network inside the car, such as obtaining real-time speed data from the car's CAN bus, using an accelerometer to measure the acceleration of the vehicle, and using a vibration sensor to detect the vibration caused by road bumps during driving. Obtaining these data on the driving status of the car can provide an important basis for the subsequent determination of the driving mode.

[0095] S303, identifying the current driving mode of the vehicle according to the driving speed, the acceleration and the degree of bumpiness, wherein the driving mode includes a congestion mode, a high-speed mode and a waiting mode.

[0096] The driving mode refers to the mode of the car in different driving states, including the slow driving mode in congestion, the high-speed driving mode, and the stationary mode when waiting. This step is to determine which of the above driving modes the car currently belongs to based on the driving data of the car.

[0097] Specifically, congestion mode means that the current car's driving speed is lower than the preset speed, the acceleration is lower than the preset acceleration, and there is no bumping. High-speed mode means that the driving speed is higher than the preset speed, the acceleration is higher than the preset acceleration, there is a linear acceleration process, and the vehicle has a small amount of bumping. Waiting mode means that the car is completely stationary, the linear speed is zero, there is no acceleration, and the vehicle will not produce bumps.

[0098] Specifically, the emergency starting power supply can comprehensively consider the real-time speed of the car, the speed of acceleration, and the degree of vibration of the vehicle during driving to evaluate whether the car is currently in a slow crawling mode in a congested state, a high-speed driving state, or a waiting and stationary mode. For example, if the speed is very low, the acceleration is very small, and the degree of bumps is also very small, it may be a slow-moving state in a congested state; if the speed is fast, the acceleration is average, and the bumps are not obvious, it may be a high-speed driving state; if the speed is close to zero, there is no acceleration, and the bumps are not obvious, it may be a stationary state while waiting. Based on these characteristic data, the emergency starting power supply can identify the specific driving mode the car is currently in.

[0099] If the current car is in the congestion mode, first determine the current power status of the car's emergency starting power supply. If the power is sufficient (not less than the preset power), calculate the current heating power according to the optimal operating temperature of the car's emergency starting power supply and the current ambient temperature, and heat the car's emergency starting power supply according to the current heating power. The calculation method is: according to the temperature difference between the two, combined with a preset temperature difference-power mapping table (the mapping table is formulated according to the thermal characteristics of the emergency starting power supply and battery performance) to determine the heating power. If the power is lower than the preset power, the heating power is reduced in proportion to the remaining power, but the heating is still performed with the goal of maintaining the basic functions of the emergency starting power supply. " If the current car is in the congestion mode, first determine the current power status of the car's emergency starting power supply. If the power is sufficient (not less than the preset power), calculate the current heating power according to the optimal operating temperature of the car's emergency starting power supply and the current ambient temperature, and heat the car's emergency starting power supply according to the current heating power. The calculation method is: according to the temperature difference between the two, combined with a pre-set temperature difference-power mapping table (the mapping table is formulated according to the thermal characteristics of the emergency starting power supply and battery performance) to determine the heating power. If the power is lower than the preset power, the heating power is reduced in proportion to the remaining power, but the heating is still performed with the goal of maintaining the basic functions of the emergency starting power supply.

[0100] If the current car is in this high-speed mode, the power supply capacity is also determined first. If the power is sufficient, based on the temperature difference between the ambient temperature and the optimal working temperature, and under the premise of ensuring normal operation, the heating power is appropriately reduced (for example, a preset power value one gear lower than the normal calculated power is used) to heat the entire car emergency starting power supply, and at the same time, the temperature of the key area is strengthened. Once the temperature of the key area approaches the lower limit of the optimal working temperature, the heating of the non-key area is stopped, and only the heating of the key area is maintained. If the power is lower than the preset power, the key area of ​​the car emergency starting power supply is heated according to the second heating power. The specific operation is that the power control module adjusts the current to the current value corresponding to the second heating power, and only supplies power to the heating elements in the key area, while closely monitoring the temperature of the key area to prevent overheating.

[0101] If the power is lower than the preset power, SHPCM will adjust the power according to the remaining power. Assuming that the remaining power is 20%, the calculated heating power will be reduced by 30% (that is, the actual heating power is 14W) according to the preset power-power adjustment strategy, and heating will be performed at this power. At the same time, SHPCM will pay close attention to the power consumption rate. If it is found that the power consumption is too fast, it will further reduce the heating power, but always ensure that the emergency starting power supply is above the minimum temperature requirement for emergency starting.

[0102] If the current car is in this high-speed mode, the emergency starting power supply will also first determine the power status. If the power is sufficient, SHPCM calculates the heating power based on the temperature difference between the ambient temperature and the optimal operating temperature, but will multiply the normal calculation result by a speed coefficient (this coefficient is determined based on the vehicle speed and experimental data, for example, when the vehicle speed exceeds 100km / h, the speed coefficient is 0.8) to appropriately reduce the heating power and reduce energy consumption. For example, the normal heating power is calculated to be 25W, and after multiplying it by the speed coefficient of 0.8, the actual heating power is 20W, and then the entire car emergency starting power supply is heated with this power. During the heating process, strengthen the monitoring of the temperature of the key area. Once the temperature of the key area approaches the lower limit of the optimal operating temperature (assuming it is 12°C), immediately start the partition heating control strategy, stop heating the non-critical areas, and only maintain heating in the key areas to ensure the normal operation of key components.

[0103] If the power is lower than the preset power, the second heating power is directly used to heat the key area. The microprocessor adjusts the current to the value corresponding to the second heating power through the IPDCU, and only supplies power to the heating elements in the key area. At the same time, the temperature monitoring module monitors the temperature of the key area in real time. When the temperature reaches the preset safety upper limit (assuming it is 18°C), the heating is suspended and the heating is resumed after the temperature drops to a certain value (such as 15°C). This cycle is repeated to maximize power saving while ensuring the normal operation of the key area.

[0104] If the current car is in the waiting mode and the battery is sufficient, SHPCM calculates the heating power based on the optimal operating temperature and the current ambient temperature. Considering that the vehicle is stationary in the waiting mode and the heat dissipation is relatively slow, an intermittent heating strategy can be adopted. For example, it is calculated that 15 minutes of heating is required per hour to maintain the temperature. SHPCM controls the heating module to heat according to this time interval, and the heating power is determined according to the calculation result (assuming 18W) each time. In this way, the emergency starting power supply can be kept at a good operating temperature and the power consumption can be effectively reduced.

[0105] If the power is lower than the preset power, continuous but lower power heating is performed according to the second heating power. The microprocessor reduces the working voltage of the heating element by a certain proportion (for example, by 20%) through the IPDCU to achieve the output of the second heating power. At the same time, the heating interval is appropriately extended (for example, the heating time is extended to 20 minutes per hour) to maintain the basic temperature of the emergency starting power supply and avoid excessive power consumption. During the entire waiting process, the power and temperature changes are continuously monitored, and the heating parameters are dynamically adjusted according to the actual situation.

[0106] S304: If the current vehicle is in the congestion mode, the current heating power is calculated according to the optimal operating temperature of the emergency starting power supply of the vehicle and the current ambient temperature, and the emergency starting power supply of the vehicle is heated according to the current heating power.

[0107] Among them, the optimal operating temperature refers to the most suitable temperature condition when the emergency starting power supply is working normally, and this temperature can make the power supply play the best working state and performance; the current ambient temperature refers to the real-time temperature of the environment inside and outside the car during driving. This step means that when it is detected that the car is currently in a congested waiting mode, the emergency starting power supply will take into account its own optimal operating temperature and detect the real-time temperature of the current environment at the same time, calculate the reasonable heating power value currently required based on the temperature difference between the two, and heat its own power supply emergency starting power supply with the calculated heating power to improve work efficiency.

[0108] Specifically, if the emergency starting power supply detects through pattern recognition that the car is in a state of slow crawling in congestion, considering that the emergency starting power supply should be in the best working state, it will first retrieve the saved optimal operating temperature parameters, such as 15 degrees Celsius. Then it will detect the real-time temperature of the environment inside the car through the temperature sensor, assuming that the current detected ambient temperature is 5 degrees Celsius. The emergency starting power supply will calculate that the temperature difference between the two is 10 degrees Celsius, and according to the corresponding relationship between the established temperature difference and the heating power, calculate the reasonable heating power value currently required, such as 20 watts. After that, the emergency starting power supply will start its own heating module according to the calculated 20 watt heating power value to heat the emergency starting power supply according to the power, so that it can work in the best state.

[0109] S305: If the current vehicle is in the high-speed mode, heating a key area of ​​the emergency starting power supply of the vehicle according to the second heating power.

[0110] Among them, the key area refers to the part of the emergency starting power supply that is crucial to ensure normal operation, such as the area where the core components such as the battery pack and the control circuit board are located. The meaning of this step is that when the monitoring recognizes that the car is currently in a high-speed driving state, considering energy saving, the emergency starting power supply will only heat its own key areas according to the preset lower second heating power to ensure that the core components can work normally.

[0111] Specifically, if the emergency starter determines that the car is currently in a high-speed driving state, the emergency starter will adopt the strategy of heating only key parts in view of the high energy consumption under high-speed driving. It will only start heating the key working areas such as the battery pack and control circuit board according to the pre-set lower second heating power value, such as 10 watts, and will not heat some non-core areas to reduce unnecessary energy loss.

[0112] S306: If the current vehicle is in the waiting mode, heating the emergency starting power supply of the vehicle according to the second heating power.

[0113] The second heating power is a relatively low heating power value that is preset. This step indicates that when the monitoring recognizes that the car is currently in a waiting and stationary state, the emergency starting power supply will heat according to the second heating power parameter saved in advance. The second heating power is a relatively low power to achieve the purpose of energy saving and heat preservation.

[0114] Specifically, if the emergency starting power supply confirms that the car is currently in a waiting state through a comprehensive judgment of the car's speed, acceleration and degree of bumps, in order to avoid excessive energy consumption, the emergency starting power supply will start a pre-set parameter value, namely the second heating power, which is lower than the normal heating power, for example 10 watts. Then the emergency starting power supply will continue to heat the entire power supply with the second heating power of 10 watts to provide sufficient heat while taking into account the purpose of energy saving.

[0115] S307: Receive a preheating operation instruction sent by the client, where the preheating operation instruction includes a preheating time and a preheating temperature.

[0116] Among them, the preheating operation instruction refers to the instruction used to control and trigger the preheating of the emergency starting power supply; the preheating time refers to the time point set by the user to start preheating; the preheating temperature refers to the target temperature set by the user to reach during preheating. This step indicates that the emergency starting power supply can receive a preheating control instruction containing predetermined heating time and temperature parameters from the client.

[0117] Specifically, in order to facilitate users to control the heating of the emergency starting power supply in advance according to their own needs, the emergency starting power supply can receive preheating operation instructions sent by an external client such as a mobile phone App according to a certain protocol. On the App side, users can set the time point when they want the emergency starting power supply to start preheating according to their travel plans and needs, such as 2 hours later, and set the target temperature they want to preheat to, such as 15 degrees Celsius. The App will generate preheating operation instructions based on these preheating time and temperature parameters in a certain format and protocol, and send them to the emergency starting power supply. The emergency starting power supply will parse the received instructions, obtain the advance heating time and target temperature parameter values ​​set by the user, and perform the corresponding heating control accordingly to complete the preheating operation of the emergency starting power supply to meet the user's personalized needs.

[0118] S308, generating a heating instruction according to the preheating time and the preheating temperature, wherein the heating instruction includes the heating module heating the emergency power supply to the preheating temperature according to the preheating power, and the preheating power is calculated based on the preheating time, the preheating temperature and the current battery temperature.

[0119] Among them, the preheating time is the advance heating time set by the user; the preheating temperature is the target temperature set by the user; and the preheating power is the heating power value calculated based on the time, the target temperature and the current temperature. This step generates a heating instruction based on the preheating time and temperature, and the instruction contains the calculated heating power.

[0120] Specifically, after receiving the preheating time and temperature, the heating module will first detect the current real-time temperature of the battery, and then calculate the required preheating power according to the thermodynamic formula based on the three parameters of preheating time, preheating target temperature and current battery temperature. The calculated preheating power will be included in the generated heating instruction. The heating instruction will be sent to the heating module, instructing it to heat the battery with the calculated preheating power until the preheating target temperature set by the user is reached.

[0121] In some embodiments, a temperature difference-power mapping table may be established for query, a temperature control PID algorithm may be used to calculate the required heating power, and a fuzzy control method may be used to obtain the optimized power.

[0122] S309: If the current battery power of the automobile emergency starting power supply is lower than the minimum power threshold, a prompt message is issued, where the prompt message is used to prompt the user to charge the automobile emergency starting power supply.

[0123] The minimum power threshold is the critical minimum value of the remaining battery power. This step is to issue a charging reminder when it is detected that the battery power is too low.

[0124] Specifically, the emergency starting power supply needs to monitor the remaining power data of the current battery pack in real time. If it detects that the remaining power is lower than the preset minimum power threshold, such as 10%, the emergency starting power supply will issue a prompt message to remind the user to charge. The prompt message can be implemented by flashing indicator lights, making sounds, or popping up charging prompts on the linked client APP, etc., which can prevent the low battery power from affecting the use of the emergency starting power supply.

[0125] In some embodiments, indicator lights and buzzers can be used for prompts, charging reminders can be pushed in the APP, and voice prompts can be issued through the vehicle infotainment emergency starting power supply.
