In order to deal with the situation that the main power supply emergency starting power supply suddenly fails, many car owners will have an emergency starting power supply on the car. The emergency starting power supply can provide the necessary power after the main power supply emergency starting power supply of the automobile fails, avoiding the driver from being in a completely helpless state. However, in a low-temperature environment, the power supply current of an ordinary lead-acid battery will decrease, resulting in insufficient starting current, so that the emergency starting power supply has a serious risk of emergency starting power supply failure.

[0003] In related technologies, a heating module can be added to the emergency starting power supply to heat the emergency starting power supply in a low-temperature environment, 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, the power loss of the emergency starting power supply itself may be large, and the emergency starting function of the emergency starting power supply may also be affected. SUMMARY

[0053] The terms used in the following embodiments of the application are only for the purpose of describing specific embodiments and are not intended to be limiting to the application. As used in the specification, the singular forms "a," "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "and / or" as used herein refer to any or all possible combinations of one or more of the associated listed items.

[0054] Hereinafter, the terms "first" and "second" are only for the purpose of description, and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features, and in the description of the embodiments of the application, the meaning of "multiple" is two or more, unless otherwise specified.

[0055] For ease of understanding, the application scenarios of the embodiments of the present application are introduced as follows: with the rapid development of automobile electronic technology, various vehicle-mounted electronic devices are increasingly widely used, and the dependence on automobile power supply systems is greatly improved. If the main power supply system suddenly fails during driving, it will directly threaten the driving safety. To solve this problem, more and more vehicle enterprises begin to configure emergency starting power supply systems on vehicles to temporarily supply power to some key electrical equipment after the main power supply fails. However, in cold weather, the low-temperature power decay problem of ordinary lead-acid batteries will seriously restrict the starting ability of the emergency power supply. If the emergency power supply cannot temporarily ensure the power supply of the key electrical equipment due to poor low-temperature starting, the driver will face a very dangerous situation. Therefore, a new type of emergency starting power supply technical solution that can detect the ambient temperature and intelligently manage battery heating is needed to ensure normal work in low-temperature environments.

[0056] For the low-temperature performance problem of ordinary batteries, some vehicle enterprises selectively use lithium batteries with better performance as emergency power supplies. However, lithium batteries are relatively expensive, and large-scale use costs too much. Some other vehicle enterprises adopt the strategy of continuously heating the battery, but continuous heating will consume a large amount of power and affect the use time. In general, the solutions in the prior art either have too high costs or consume too much power, and cannot well meet the working requirements of the emergency power supply in low-temperature environments.

[0057] The present application provides an ultra-low-temperature discharge automobile emergency starting power supply heating method. The method can detect the ambient temperature, predict the starting probability, calculate the heating target temperature, and determine the heating strategy. For example, if it is predicted that starting may be needed after 2 hours, and the temperature will be lower than -10°C, the heating target temperature of each period within the next 2 hours will be calculated, and if the power is sufficient, heating will be performed according to the target temperature; if the power is insufficient, only the key components will be heated. The strategy can also be adjusted according to the driving state. The method realizes intelligent and refined temperature control management, which not only ensures low-temperature starting, but also saves energy consumption.

[0058] For ease of understanding, the method provided by the present embodiment is described in the following flow. Figure 1 , a flowchart of the ultra-low-temperature discharge automobile emergency starting power supply heating method in the embodiments of the present application.

[0059] S101, vehicle data, battery data, environmental data of the current environment, and usage mode data of the automobile emergency starting power supply of the current automobile are obtained.

[0060] Among them, the vehicle data refers to the driving speed, fuel consumption and other data of the automobile, the battery data refers to the usage data of the starting battery of the current automobile, such as voltage, power, temperature and other usage parameters, the environmental data refers to the environmental temperature data, and the usage mode data refers to the usage record of the emergency starting power supply.

[0061] Specifically, in order to predict the required emergency starting power supply heating, it is necessary to collect the current running state of the automobile and the use state data of the emergency starting power supply, including obtaining the current vehicle running data such as vehicle speed and fuel consumption through the relevant sensors of the automobile, obtaining the working voltage, power, temperature and other use parameters of the starting battery of the current automobile from the starting battery, obtaining the current environmental temperature, humidity and other environmental parameters from the environmental monitoring equipment, and extracting the use mode data of the number of times of starting of the emergency starting power supply from the use log of the emergency starting power supply.

[0062] In some embodiments, the vehicle running data can be obtained through the CAN bus of the automobile; the starting battery parameters are collected by using the battery management emergency starting power supply, the environmental information is monitored by connecting the meteorological station equipment; the use mode data of the emergency power supply is extracted by analyzing the use log of the database; optionally, the vehicle data can also be collected by using the additional sensors of the automobile; the starting battery regularly reports the state data, and the environmental information is retrieved by using the online weather forecast; the power starting rule is analyzed by data mining.

[0063] S102, input the vehicle data, the battery data, the environmental data and the use mode data into a probability prediction model to obtain a starting probability of needing to use the automobile emergency starting power supply in a preset time period.

[0064] The probability prediction model can predict the probability of using the emergency starting power supply according to the input data, and the starting probability refers to the possibility of using the emergency starting power supply at a given future time. The step of obtaining the probability of starting the power supply is calculated by the prediction model.

[0065] Specifically, the emergency starting power supply inputs the collected automobile data, battery data, environmental data and use mode data into a pre-trained probability prediction model. The prediction model can comprehensively consider various influencing factors to evaluate the probability of needing to start the emergency starting power supply at a given future time, i.e. the starting probability. For example, when the environmental temperature is too low, the starting probability will increase. Calculating the accurate starting probability can provide a basis for subsequent preheating decisions.

[0066] The construction process of the probability prediction model is as follows:

[0067] First, vehicle data, battery data, environmental data and use mode data need to be collected. The vehicle data includes speed and fuel consumption, the battery data includes voltage, power and battery temperature, the environmental data includes environmental temperature and humidity, and the use mode data includes the number of times of starting of the emergency starting power supply and the time.

[0068] Data collection examples: vehicle data, speed 60 km / h, fuel consumption 8 L / 100 km, battery data, voltage 12.5 V, remaining power 80%, battery temperature 15℃, environmental data, temperature 5℃, humidity 60%, usage pattern data: 2 emergency power starts in the past 24 hours.

[0069] Input data: vehicle data: [speed, fuel consumption], battery data: [voltage, power, temperature], environmental data: [temperature, humidity], usage pattern data: [number of starts, duration of starts]; output data: prediction result: probability of starting, range 0 to 1.

[0070] Training data, collect 20,000 emergency power start records in a year as training data, each record contains input feature information and start label. Divide the data into training data set and validation data set in proportion; data preprocessing, normalization: normalize input features with different dimensions such as temperature, speed, voltage, missing value processing: supplement reasonable value or directly eliminate missing data, encoding processing: one-hot encoding for classification data such as speed range, use PyTorch to build model framework, define multi-layer fully connected neural network, including input layer, 2 hidden layers and output layer, hidden layer uses ReLU activation function, output layer uses Sigmoid activation function to get probability output, loss function selects cross entropy loss function, optimizer selects Adam algorithm, put the processed data into the model for training, optimize the loss function, update the parameters, evaluate the effect on the validation set, adjust the model structure and hyperparameters, evaluate the performance on independent test set, such as AUC curve, investigate feature importance, and analyze the model in depth.

[0071] S103, if the future temperature data is lower than the preset temperature threshold, obtain the environmental temperature change trend in the preset time period, the preset time period is the time range between the current time point and the preset time point, and the preset time period contains a number of preset heating time periods.

[0072] Wherein, the future temperature data is the predicted temperature at the preset time point; the preset temperature threshold is the temperature standard for judging whether heating is needed; the environmental temperature change trend is the temperature change pattern over time in the future period; the preset time period is the time range to be considered in the future; the preset heating time period is the time interval that may be heated.

[0073] Specifically, if the future temperature data of 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, additional trend information of the ambient temperature in a time period from the current time point to the preset time point needs to be obtained. The preset time period can include one or more preset heating time periods in which preheating can be performed. The temperature trend is obtained to calculate the target temperature required to be reached in each possible heating time period.

[0074] In some embodiments, the temperature curve data in the next week can be obtained from a weather station; the temperature distribution in the next month can be calculated by using a temperature prediction model. Optionally, the real-time temperature can also be detected periodically by an environmental sensor; and the future temperature approximation can be obtained by data correction. It can be understood that the trend information of the ambient temperature in a specific preset time range can also be obtained in other ways.

[0075] S104, calculate a target temperature set including the target temperature of each preset heating time period according to the trend information of the ambient temperature and the normal battery working temperature, the target temperature being the difference between the real-time ambient temperature and the normal battery working temperature.

[0076] The normal battery working temperature is the optimal working temperature of the battery of the emergency starting power supply; the target temperature is the temperature to which the battery needs to be raised; and the target temperature set includes the target temperature values corresponding to multiple time periods. This step is to calculate the target temperature required to be reached in each possible heating time period.

[0077] Specifically, the emergency starting power supply can obtain the trend information of the future ambient temperature and the normal battery temperature required for the emergency starting power supply to work, and calculate the target temperature to which the battery needs to be raised in each possible preset heating time period to work in the best state. The target temperature can be obtained by calculating the difference between the current ambient temperature and the optimal working temperature. Repeating the calculation can obtain a target temperature set including the target temperatures corresponding to multiple heating time periods.

[0078] In some embodiments, the target temperature can be calculated by the temperature difference method; and 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; and the sliding average algorithm can be used to eliminate the influence of ambient temperature fluctuations. It can be understood that the emergency starting power supply can also calculate the target temperature information required in each heating time period in other ways.

[0079] S105, determine the emergency power supply heating strategy according to the current power of the automobile emergency starting power supply and the target temperature set.

[0080] Wherein, the current power is the remaining power of the emergency starting power supply; the target temperature set is the target temperature required to be reached in each preset heating time period; and the emergency power supply heating strategy is a heating scheme formulated according to the power and the target temperature. This step is to determine the heating strategy based on the current power and the target temperature.

[0081] In some embodiments, if there is a target temperature greater than a preset temperature threshold in the current preset heating time period, 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, when the current power is not lower than the preset power.

[0082] S106, generating a heating instruction according to the emergency power supply heating strategy and sending it to the heating module, so that the heating module heats the automobile emergency starting power supply.

[0083] Wherein, the heating instruction is a control execution signal output according to the heating strategy; and the heating module is a component for physical heating in the emergency starting power supply. This step is to generate a heating control instruction and issue it to the heating module to start heating.

[0084] Specifically, after determining the heating strategy of the emergency starting power supply, the emergency starting power supply needs to generate a matching specific heating control instruction for controlling the work of the heating module. These control instructions will include heating start time, heating device selection, heating intensity and other parameters. The emergency starting power supply sends these heating instructions to the special heating module through the network inside the emergency starting power supply. After receiving the instructions, the heating module will start physical heating of the battery according to the required time, intensity and other requirements of the instructions.

[0085] In some embodiments, the XML format of the heating instruction can be designed, and the instruction information can be packaged by using JSON encoding. Optionally, the instruction parameters can also be issued through a database mode, and the network API can be used to implement the instruction issuing. It can be understood that the emergency starting power supply can also generate instructions and issue them to the heating module to start heating the emergency starting power supply through other ways.

[0086] In combination with the above scenarios, the method provided by the present embodiment is further described in more detail. Please refer to Figure 2 , another flowchart of the method for heating the automobile emergency starting power supply with ultra-low temperature discharge in the embodiment of the present application.

[0087] S201, determining an emergency power supply heating strategy according to the current power of the automobile emergency starting power supply and the target temperature set.

[0088] It can be understood that this step is similar to step S105, which will not be described here.

[0089] S202, if the current power is not lower than the preset power and if there is a target temperature greater than a preset temperature threshold in the current preset heating time period, calculating a current heating power set of each current preset heating time period according to the current temperature and a first stage target temperature, the first stage target temperature being a target temperature corresponding to a first period in the plurality of preset heating time periods.

[0090] wherein the preset power is a threshold for judging sufficient power, the current temperature is a real-time temperature of the emergency starting power environment; the target temperature is a temperature to be reached, and the step is to calculate the heating power of each period under the condition that the power is sufficient.

[0091] Specifically, if the emergency starting power detects that the current remaining power is higher than the preset minimum power threshold for judging sufficient power, it will obtain the current environment temperature, for example 5°C, and then find the period in which the target temperature is greater than the preset temperature threshold in the plurality of heating periods, for example the target temperature of the first period is 15°C. The emergency starting power will calculate the temperature difference of 10°C between the current temperature 5°C and the target temperature 15°C of the first period, and calculate the heating power required for the first period according to the thermodynamic model. Repeating the calculation can obtain the heating power required for each period to form a current heating power set.

[0092] In some embodiments, the heating power can be calculated by temperature difference; the power can be obtained by using a thermodynamic model. Alternatively, the heating power can be calculated by using temperature-power curve fitting and machine learning.

[0093] S203, heating the automobile emergency starting power in each current preset heating time period according to all current heating powers in the current heating power set.

[0094] wherein the heating power set contains the heating power value required to be reached calculated for each preset heating time period. The step is to control each period according to the power value in the heating power set to achieve accurate segmented heating.

[0095] Specifically, the emergency starting power will obtain the current heating power set, which contains the heating power value corresponding to each preset heating period, for example 20W for the first period and 15W for the second period. After obtaining the set, the emergency starting power will enable the heating device to heat when entering the corresponding period. For example, it will control the heating device to work at a power of 20W when entering the first heating period, and adjust to work at a power of 15W when entering the second heating period. By accurately controlling the corresponding relationship between the period and the power value, the emergency starting power can achieve the goal of segmented accurate heating, which meets the temperature requirements of different periods and improves the flexibility and controllability of heating.

[0096] In some embodiments, the working voltage and current of the heating device can be modulated to achieve accurate power control; pulse width modulation can also be used to adjust the average power of the heating device; a feedback control model such as a PID algorithm can also be established to adjust the power output according to the deviation.

[0097] S204, if the target temperature in the other preset heating time period is not greater than the preset temperature threshold, the first heating power is used to heat the automobile emergency starting power supply, and the other preset heating time period is a time period other than the current preset heating time period in all preset heating time periods. The all preset heating time periods are all the preheating time periods in the time range from the current time point to the preset time point.

[0098] Wherein, the preset temperature threshold is a temperature standard for judging whether heating is needed; the first heating power is a preset low power for heating. This step is to use lower heating power in a period when the temperature demand of the emergency starting power supply is not high.

[0099] Specifically, when the emergency starting power supply calculates the heating power for each period, it will first determine whether the target temperature of the period is higher than the preset temperature threshold. If the target temperature of a 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 first low power, for example, 5W, to heat the period. This can avoid completely not heating because the target temperature of a period is not high, which causes power waste to other periods. By using low power heating, basic temperature support can be provided.

[0100] In some embodiments, the working voltage of the heating device can be adjusted to reduce the power; the heating cycle can also be controlled to reduce the average power; and a temperature-power mapping table can also be used to achieve low-power heating.

[0101] S205, in the case where the current power of the automobile emergency starting power supply is lower than the preset power, if the target temperature in 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 during which the heating measure is actually taken when heating the automobile emergency starting power supply.

[0102] Wherein, the preset power is a threshold for judging insufficient power; the second heating power is a backup low power for heating; the core working component refers to a component that plays a key role in the emergency starting power supply, such as a battery core group, a circuit control board, and a power management module. These components are the core of the starting power supply to realize normal power supply function. This step is to heat only the key components at low power when the power of the emergency starting power supply is insufficient.

[0103] Specifically, if the emergency starting power supply detects that the current power data is lower than the preset power shortage threshold, it will re-evaluate the heating strategy for each period. For periods with high target temperature, the emergency starting power supply will only turn on the heating of the core component area of the corresponding battery, and use the preset second backup low power, for example 20W, to heat to ensure the normal operation of the key components. This can effectively save power and prolong the use time of the emergency starting power supply.

[0104] In some embodiments, only the core components can be heated by local heating technology; independent power control can also be used to power the key areas. Optionally, the power distribution of the key areas can also be adjusted by priority management.

[0105] 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 precisely controls the power by adjusting the current size 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 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 realize an output less than the first heating power.

[0106] In terms of regional heating distribution, a partitioned heating layout is adopted. Key areas such as battery core groups and circuit control boards are arranged with independent heating elements, which are directly connected to specific output ports of the power control module to ensure that only the key areas are heated when the second heating power is used. Non-key areas such as battery housings and cooling fans are responsible for another group of heating elements, which are connected to other ports of the power control module, and only these non-key areas are heated at a lower power when the third heating power is used. At the same time, the time distribution of heating different areas can be set according to actual needs, for example, when the power is tight, the key areas are preferentially heated for a certain time, and then the non-key areas are maintained for a short time.

[0107] In the internal of the automobile emergency starting power supply, an intelligent power distribution and control unit (IPDCU) is provided, which is specially used to realize the accurate control and reasonable distribution of the second heating power and the third heating power. The IPDCU is composed 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 by the second heating power according to the preset algorithm. The power regulation circuit adopts pulse width modulation (PWM) technology to accurately adjust the current size in the heating circuit by changing the duty cycle of the pulse signal, thereby realizing 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 according to the battery voltage (assuming 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 realizing the heating of the key areas (such as battery core group, circuit control board and other core components)

[0108] For the control of the third heating power, the 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 calculates the corresponding current value according to the preset power level relationship (for example, the third heating power is set to be 50% of the first heating power), and limits the current to this value through the power regulation circuit. In terms of hardware structure, the key areas and non-key areas (such as battery shell, cooling fan, control panel outer frame, wiring slot, external connection port, etc.) are respectively arranged with independent heating elements. The heating elements of the key areas are made of high thermal conductivity materials to ensure that the heat can be quickly and effectively transferred to the core components, and they are directly connected to the specific power output port of the IPDCU to ensure that only the heating elements of the key areas can obtain electric energy for heating when the second heating power is output. The heating elements of the non-key areas are made of ordinary thermal conductive materials, which are connected to another independent power output port of the IPDCU, and only the non-key areas are heated at low power when the third heating power is output.

[0109] In order to realize the reasonable distribution of heating time in different areas, a time distribution module is built in the IPDCU. When the power is lower than the preset power, the module formulates the heating time strategy of different areas according to the remaining power ratio and environmental temperature and other factors. For example, when the power remaining is 30%, the key areas are heated for 80% of the time in a heating period, and then the non-key areas are provided with a short heating pulse for 20% of the remaining time to maintain the basic temperature and avoid affecting the overall performance due to too low temperature. At the same time, the IPDCU also monitors the temperature of each area in real time, dynamically adjusts the heating power and time distribution through the signal feedback of the temperature sensor, and ensures that the heating process meets the working requirements of the emergency starting power supply and saves the power to the greatest extent

[0110] S206, in the case that the current power of the automobile emergency starting power supply is lower than the preset power, heating the non-critical area with a third heating power, the third heating power being lower than the first heating power, the non-critical area being a non-core working component of the automobile emergency starting power supply.

[0111] Examples of the non-core working component include: a battery shell, as an external package of the battery, not a core component of power generation, a cooling fan, for cooling the circuit board, not critical to power supply function, a control panel outer frame: a protective frame outside the panel, not a critical part of the control, a wiring slot, a channel for laying wires, not critical to power supply function, an external connection port, an interface for connecting with external equipment, not critical to starting power supply function.

[0112] Specifically, if it is detected that the current power is lower than the preset power threshold, indicating that the power is relatively tight, the emergency starting power supply will reduce the heating intensity of the non-critical area. It will use a preset third low heating power, for example, 10W, to heat a small amount of the non-critical area of the battery, such as the shell, which can further reduce unnecessary power consumption and leave more power for the critical components.

[0113] In some embodiments, the low-power heating of the non-critical area can be achieved by local heating technology; a separate low-power power supply can also be used to supply power for heating the non-critical area, and priority management means can be further used to reduce the heating power distribution of the non-critical area.

[0114] S207, generating a heating instruction according to the emergency power supply heating strategy and sending it to the heating module, so that the heating module heats the automobile emergency starting power supply.

[0115] 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 to generate a control instruction for the heating module according to the determined heating strategy of the emergency starting power supply.

[0116] Specifically, after calculating and determining the heating strategy of the emergency starting power supply, a matching specific heating control instruction needs to be generated and sent to the heating module. These instructions will include heating time, heating power, heating area and other parameters. The emergency starting power supply will send these heating instructions to the dedicated heating module through the internal network. After receiving the instructions, the heating module will control the corresponding components to start heating and physically heat the battery pack.

[0117] In combination with the above scenario, the method provided by the present embodiment is further described in more detail. Please refer to Figure 3FIG. 2 is another flowchart illustrating a method for heating an ultra-low temperature discharge automotive emergency starting power supply according to an embodiment of the present application.

[0118] S301, generating a heating instruction according to the emergency power supply heating strategy and sending the heating instruction to a heating module, so that the heating module heats the automotive emergency starting power supply.

[0119] It can be understood that this step is similar to step S105, and will not be described here.

[0120] S302, obtaining a driving speed, an acceleration, and a jolt degree of the current vehicle.

[0121] The driving speed can reflect the motion state of the vehicle, the acceleration represents the speed change of the vehicle, and the jolt degree represents the vibration and shock of the vehicle caused by the uneven road surface during driving. The purpose of this step is to obtain real-time running data of the vehicle during driving.

[0122] Specifically, in order to evaluate the current driving state of the vehicle, the emergency starting power supply needs to collect the speed index, acceleration index, and jolt degree of the vehicle during driving. These data can be obtained through the sensor network inside the vehicle, for example, obtaining real-time speed data from the CAN bus of the vehicle, using an acceleration sensor to measure the acceleration of the vehicle, and using a vibration sensor to detect the vibration caused by the uneven road surface during driving. Obtaining these vehicle driving state data can provide an important basis for subsequent determination of the driving mode.

[0123] S303, identifying a driving mode of the current vehicle according to the driving speed, the acceleration, and the jolt degree, the driving mode including a congestion mode, a high-speed mode, and a waiting mode.

[0124] The driving mode represents the mode of the vehicle in different driving states, including a slow driving mode in congestion, a high-speed driving mode, and a static mode in waiting. This step is to determine which driving mode the vehicle currently belongs to according to the driving data of the vehicle.

[0125] Specifically, the congestion mode refers to that the driving speed of the current vehicle is lower than the preset driving speed, the acceleration is lower than the preset acceleration, and there is no jolt. The high-speed mode refers to that the driving speed is higher than the preset driving speed, the acceleration is higher than the preset acceleration, there is a linear acceleration process, and the vehicle has a small amount of jolt. The waiting mode refers to that the vehicle is completely static, the linear speed is zero, there is no acceleration, and the vehicle will not produce jolt.

[0126] Specifically, the emergency starting power supply can comprehensively consider the real-time speed of the automobile, the acceleration, and the vibration degree of the vehicle during driving to evaluate whether the automobile is currently in a slow crawling mode in a congested state, a high-speed driving state, or a waiting stationary mode. For example, if the speed is low, the acceleration is small, and the vibration degree is also small, it may belong to the slow crawling state in congestion; if the speed is fast, the acceleration is general, and the vibration is not obvious, it may belong to the high-speed driving state; if the speed is close to zero, there is no acceleration, and the vibration is not obvious, it may belong to the stationary state in waiting. According to these characteristic data, the emergency starting power supply can identify the specific driving mode of the automobile at present.

[0127] If the current automobile is in the congested mode, first determine the current power of the automobile emergency starting power supply. If the power is sufficient (not less than the preset power), calculate the current heating power according to the best working temperature of the automobile emergency starting power supply and the current environment temperature and heat the automobile emergency starting power supply according to the current heating power. The calculation method is: according to the temperature difference between the two, combined with the pre-set temperature difference-power mapping table (the mapping table is formulated according to the thermal characteristics of the emergency starting power supply and the battery performance) to determine the heating power. If the power is lower than the preset power, reduce the heating power in proportion according to the remaining power, but still heat with the goal of maintaining the basic function of the emergency starting power supply.

[0128] If the current automobile is in the congested mode, first determine the current power of the automobile emergency starting power supply. If the power is sufficient (not less than the preset power), calculate the current heating power according to the best working temperature of the automobile emergency starting power supply and the current environment temperature and heat the automobile emergency starting power supply according to the current heating power. The calculation method is: according to the temperature difference between the two, combined with the pre-set temperature difference-power mapping table (the mapping table is formulated according to the thermal characteristics of the emergency starting power supply and the battery performance) to determine the heating power. If the power is lower than the preset power, reduce the heating power in proportion according to the remaining power, but still heat with the goal of maintaining the basic function of the emergency starting power supply.

[0129] If the current car is in the high-speed mode, the power supply capacity is also determined first. If the capacity is sufficient, the heating power is appropriately reduced (for example, a preset power value one step lower than the normal calculated power value) to heat the entire car emergency starting power supply under the premise of ensuring normal operation according to the temperature difference between the ambient temperature and the optimal working temperature, and the monitoring of the temperature of the key area is strengthened. Once the temperature of the key area approaches the lower limit of the optimal working temperature, heating of the non-key area is stopped, and only the key area is heated. If the capacity is lower than the preset capacity, 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 the heating elements of the key area are powered, while the temperature of the key area is closely monitored to prevent overheating.

[0130] If the capacity is lower than the preset capacity, the SHPCM adjusts the power according to the remaining capacity. Assuming that the remaining capacity is 20%, the calculated heating power is reduced by 30% (i.e., the actual heating power is 14W) according to the preset capacity-power adjustment strategy, and heating is performed according to this power. At the same time, the SHPCM closely monitors the power consumption rate, and if it is found that the power consumption is too fast, the heating power will be further reduced, but it will always ensure that the emergency starting power supply is above the minimum temperature requirement for emergency starting.

[0131] If the current car is in the high-speed mode, the power supply capacity is also determined first. If the capacity is sufficient, the heating power is appropriately reduced (for example, a preset power value one step lower than the normal calculated power value) to heat the entire car emergency starting power supply under the premise of ensuring normal operation according to the temperature difference between the ambient temperature and the optimal working temperature, and the monitoring of the temperature of the key area is strengthened. Once the temperature of the key area approaches the lower limit of the optimal working temperature, heating of the non-key area is stopped, and only the key area is heated. If the capacity is lower than the preset capacity, 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 the heating elements of the key area are powered, while the temperature of the key area is closely monitored to prevent overheating.

[0132] If the capacity is lower than the preset capacity, the SHPCM adjusts the power according to the remaining capacity. Assuming that the remaining capacity is 20%, the calculated heating power is reduced by 30% (i.e., the actual heating power is 14W) according to the preset capacity-power adjustment strategy, and heating is performed according to this power. At the same time, the SHPCM closely monitors the power consumption rate, and if it is found that the power consumption is too fast, the heating power will be further reduced, but it will always ensure that the emergency starting power supply is above the minimum temperature requirement for emergency starting.

[0133] If the current car is in the waiting mode, if the power is sufficient, the SHPCM calculates the heating power according to the optimal working temperature and the current environmental temperature. Considering that the vehicle is stationary in the waiting mode, the heat dissipation is relatively slow, and an intermittent heating strategy can be adopted. For example, it is calculated that 15 minutes of heating per hour is needed to maintain the temperature, and the 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). In this way, the emergency starting power can be kept at a good working temperature, and the power consumption can be effectively reduced.

[0134] If the power is lower than the preset power, continuous but lower power heating is carried out according to the second heating power. The microprocessor reduces the working voltage of the heating element by a certain percentage (for example, by 20%) through the IPDCU, so as to realize the output of the second heating power. At the same time, the heating interval time is appropriately prolonged (for example, the heating time per hour is prolonged to 20 minutes), so as to maintain the basic temperature of the emergency starting power and avoid excessive consumption of power. During the whole waiting process, the power and temperature changes are constantly monitored, and the heating parameters are dynamically adjusted according to the actual situation.

[0135] S304, if the current car is in the congestion mode, the current heating power is calculated according to the optimal working temperature and the current environmental temperature of the car emergency starting power, and the car emergency starting power is heated according to the current heating power.

[0136] The optimal working temperature refers to the most suitable temperature condition when the emergency starting power works normally, which can make the power work in the best state and performance; the current environmental temperature refers to the real-time temperature of the environment inside and outside the car during driving. The meaning of this step is that when it is monitored that the car is currently in the waiting mode of congestion, the emergency starting power will consider its optimal working temperature, and at the same time detect the real-time temperature of the current environment, calculate the reasonable heating power value required at present according to the temperature difference of the two, and heat the emergency starting power itself with the calculated heating power, in order to improve the working efficiency.

[0137] Specifically, if the emergency starting power supply monitors that the car is in a slow crawl state of congestion through mode recognition, considering that the emergency starting power supply itself is to be in the best working state, it will first retrieve the saved optimal working temperature parameter, for example, 15 degrees Celsius. Then it will detect the real-time temperature of the environment in which it is located through the temperature sensor, assuming that the currently detected environmental 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 established correspondence between the temperature difference and the heating power, it will calculate the reasonable heating power value required at the moment, for example, 20 watts. Then, the emergency starting power supply will start the heating module of itself according to the calculated 20-watt heating power value to heat the emergency starting power supply according to the power, so as to make itself work in the best state.

[0138] S305, if the current car is in the high-speed mode, heating the key area of the car emergency starting power supply according to the second heating power.

[0139] The key area refers to the part of the emergency starting power supply that is crucial to ensuring normal work, such as the area where the battery pack, control circuit board and other core components are located. The meaning of this step is that when it is monitored and identified that the car is currently in a high-speed driving state, considering energy saving, the emergency starting power supply will heat only the key area of itself according to the pre-set lower second heating power to ensure that the core components can work normally.

[0140] Specifically, if the emergency starting power supply determines that the car is currently in a high-speed driving state, considering the large energy consumption under high-speed driving, the emergency starting power supply will adopt the strategy of heating only the key components. It will start heating only the battery pack, control circuit board and other key working areas of itself according to the pre-set lower second heating power value, for example, 10 watts, without heating some non-core areas, in order to reduce unnecessary energy loss.

[0141] S306, if the current car is in the waiting mode, heating the car emergency starting power supply according to the second heating power.

[0142] The second heating power is a relatively low heating power value set in advance. This step means that when it is monitored and identified 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, which is a relatively low power to achieve the purpose of energy saving and heat preservation.

[0143] Specifically, if the emergency starting power supply confirms that the car is currently in a state of waiting for static through the comprehensive judgment of the speed, acceleration and jolt degree of the car, considering the problem of avoiding excessive energy consumption, the emergency starting power supply will start a pre-set parameter value, i.e. a second heating power, which is lower than the normal heating power, for example, 10 watts, and then the emergency starting power supply will continuously heat the entire emergency starting power supply at the second heating power of 10 watts to provide sufficient heat while taking into account the energy saving purpose.

[0144] S307, receiving the preheating operation instruction sent by the client, wherein the preheating operation instruction contains a preheating time and a preheating temperature.

[0145] The preheating operation instruction is an instruction for controlling and triggering the preheating of the emergency starting power supply; the preheating time is the time point at which the user hopes to start preheating; and the preheating temperature is the target temperature at which the user hopes to preheat. This step indicates that the emergency starting power supply can receive the preheating control instruction containing the preheating time and temperature parameters from the client.

[0146] Specifically, in order to facilitate the user to preheat the emergency starting power supply according to his own needs, the emergency starting power supply can receive the preheating operation instruction sent by the external client such as the mobile phone App according to a certain protocol. At the App end, the user can set the time point at which he hopes the emergency starting power supply to start preheating, such as 2 hours later, and set the target temperature at which he hopes to preheat, such as 15 degrees Celsius. The App will generate a preheating operation instruction according to the preheating time and temperature parameters in a certain format and protocol, and send it to the emergency starting power supply. The emergency starting power supply will analyze the received instruction to obtain the preheating time and target temperature parameters set by the user, and execute the corresponding heating control according to the parameters to complete the preheating operation of the emergency starting power supply, so as to meet the individual needs of the user.

[0147] S308, generating a heating instruction according to the preheating time and the preheating temperature, wherein the heating instruction contains the heating of the emergency power supply to the preheating temperature by the heating module according to the preheating power calculated from the preheating time, the preheating temperature and the current battery temperature.

[0148] The preheating time is the preheating 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 from the time, the target temperature and the current temperature. This step is to generate a heating instruction according to the preheating time and temperature, and the instruction contains the calculated heating power.

[0149] Specifically, after receiving the preheating time and temperature, the heating module first detects the real-time temperature of the current battery, and then calculates the required preheating power according to the preheating time, the preheating target temperature and the current battery temperature according to a thermodynamic formula. The calculated preheating power is included in the generated heating instruction. The heating instruction is sent to the heating module to instruct it to heat the battery at the calculated preheating power until the preheating target temperature set by the user is reached.

[0150] In some embodiments, a temperature difference-power mapping table can be established for query, a temperature control PID algorithm can be used to calculate the required heating power, and a fuzzy control method can be used to obtain the optimized power.

[0151] S309, if the current battery power of the automobile emergency starting power supply is lower than the minimum power threshold, a prompt information is sent, and the prompt information is used to prompt the user to charge the automobile emergency starting power supply.

[0152] The minimum power threshold is a critical minimum value of the remaining battery power, and the step is to send a charging prompt when it is detected that the battery power is too low.

[0153] Specifically, the emergency starting power supply needs to monitor the remaining power data of the current battery pack in real time. If it is detected that the remaining power is lower than the preset minimum power threshold, for example, 10%, the emergency starting power supply will send a prompt information prompting the user to charge, and the prompt information can be realized by flashing the indicator light, sounding the buzzer, or popping up the charging prompt on the linked client APP. This can avoid the influence of low battery power on the use of the emergency starting power supply.

[0154] In some embodiments, the indicator light and the buzzer can be used for prompting, the APP can be used for pushing the charging prompt, and the vehicle information entertainment emergency starting power supply can be used for sending a voice prompt.

Please refer to Figure 4 , which is a schematic structural diagram of an entity device of the automobile emergency starting power supply in the embodiments of the application.
