Description

Technical Field

[0001] The present application relates to the technical field of automotive power supplies, and particularly to a method and device for protecting the low-temperature start of an automotive power supply based on a supercapacitor. Background Art

[0002] With the rapid development of the automotive industry, the starting performance of vehicles in low-temperature environments has gradually become one of the important factors concerned by consumers. The low-temperature environment poses higher requirements on the power supply system of automobiles. Especially in cold regions, the battery performance will decrease significantly, thus affecting the starting of the engine. Therefore, finding effective low-temperature starting technologies has become a major research hotspot in the industry. Among them, supercapacitors, due to their fast charge and discharge characteristics and good temperature adaptability, have gradually become a solution that has attracted much attention.

[0003] In related technical means, the automotive power supply system usually relies on lithium batteries or lead-acid batteries to provide starting current. However, the chemical reaction rate of these batteries slows down at low temperatures, and the internal impedance increases, resulting in insufficient output capacity. In order to improve the low-temperature starting performance, some technical solutions have begun to adopt the method of combining supercapacitors with batteries. The fast response ability of the supercapacitor complements the deficiencies of the battery in a low-temperature environment and can provide high-pulse current in a short time, thereby improving the starting success rate of the engine and reducing the starting time.

[0004] For the above technical solutions, although effective low-temperature start protection can be achieved by combining supercapacitors with batteries, during the energy conversion process between the supercapacitor and the battery, overcharging or undercharging is likely to occur, which may further lead to damage to the power supply device.

[0028] The following will further illustrate the technical solutions of the present invention with reference to the accompanying drawings and through specific implementation manners.

[0029] Embodiment 1:

[0030] As Figure 1 shown, this application provides a low-temperature startup protection method for an automotive power supply based on a supercapacitor, which is applied to an automotive startup control system. The automotive startup control system includes a control unit, a battery unit, and a supercapacitor unit. The protection method includes steps S100 to S600.

[0031] Step S100: Obtain the temperature parameter of the current external environment, define the threshold for the temperature parameter, and obtain the definition result.

[0032] In this step, the external environment temperature is detected in real time through a sensor, and this temperature is compared with a preset threshold to determine whether the current environment meets the conditions for low-temperature startup. Specifically, the external temperature data is obtained by using an ambient temperature sensor and compared with the preset threshold stored in the control unit, thereby generating a definition result.

[0033] For example, if the detected ambient temperature is lower than -10°C, the defined result is considered to be lower than the preset threshold.

[0034] Step S200: If the defined result is lower than the preset threshold, the control unit controls the supercapacitor unit to provide starting current for the vehicle's engine.

[0035] In this step, according to the defined result, the control unit activates the supercapacitor unit to quickly release the stored electrical energy, so as to provide the high-pulse current required for starting the engine. Specifically, the control unit turns on the discharge switch of the supercapacitor unit, and transfers the energy in the supercapacitor to the starting circuit to achieve a quick start.

[0036] For example, when the temperature is lower than the threshold, the supercapacitor discharges rapidly, providing a starting current of 300 A to support the engine start.

[0037] Step S300: After the vehicle's engine starts successfully, the control unit issues a control signal, and processes the control signal to obtain a first signal and a second signal.

[0038] In this step, after the engine starts, the control unit generates and sends a control signal, which is divided into two paths for processing: one path generates a first signal for powering on-board electrical appliances, and the other path generates a second signal for charging the supercapacitor. Specifically, the control unit uses a signal distributor to divide the sent control signal into two paths and processes them independently.

[0039] For example, the signal after starting is divided into two parts to meet different power management requirements.

[0040] Step S400: Filter the first signal to obtain a filtered signal and a first amplified signal, amplify the control signal using the filtered signal to obtain an amplified control signal, modulate the first amplified signal based on the amplified control signal to obtain a modulated signal, and control the battery unit to power the vehicle's electrical appliances according to the modulated signal.

[0041] In this step, the filter removes the noise in the first signal and amplifies it to ensure stable voltage and current are provided for the on-board electrical appliances. Specifically, the filtered signal undergoes signal gain through an amplifier, and then the voltage waveform is adjusted through a modulation circuit to form a stable modulated signal, which powers the on-board electrical appliances in a constant voltage mode.

[0042] For example, the amplified signal is increased to 12 V to adapt to the voltage requirements of on-board electronic devices.

[0043] Step S500: Amplify the second signal to obtain a second amplified signal, compare the second amplified signal with the modulation signal, generate a comparison signal based on the comparison result, and control the battery unit to charge the supercapacitor unit according to the comparison signal.

[0044] In this step, the second signal is amplified to increase the signal strength and then compared with the modulation signal to ensure that the charging voltage matches the acceptable threshold of the supercapacitor. Specifically, through a comparison circuit, the amplified second signal and the modulation signal are compared in terms of voltage level, and a corresponding comparison signal is generated, which is used to control the output of the battery to optimize the charging process of the supercapacitor.

[0045] For example, if the comparison signal indicates that the charging voltage is too low, the charging power is enhanced to ensure effective charging of the supercapacitor.

[0046] Step S600: Integrate the modulation signal and the comparison signal, generate an integration signal based on the integration result, and control the control unit to monitor the energy conversion between the battery unit and the supercapacitor unit in real time according to the integration signal.

[0047] In this step, an integration circuit combines and analyzes the modulation signal and the comparison signal to extract comprehensive power management information to form an integration signal. Specifically, through a signal processing algorithm, the two sets of signal data are weighted and averaged to generate a dynamic integration signal, which is used to feedback to the control unit to achieve real-time monitoring and adjustment of the energy conversion process.

[0048] For example, the integration signal monitors the discharge and charging efficiency in real time to ensure that the system operates in an optimal state.

[0049] In this embodiment, it starts by obtaining the temperature parameters of the current external environment, and then thresholds these temperature parameters to determine whether they are lower than a preset threshold. If the determination result shows that the temperature parameters are lower than the threshold, the control unit controls the supercapacitor unit to provide a starting current for the vehicle's engine. Once the vehicle engine is successfully started, the control unit issues a control signal, which then undergoes signal processing to obtain two outputs: a first signal and a second signal. After the first signal is filtered, the control signal is amplified using the filtered signal, and the first amplified signal is signal-modulated to control the battery unit to supply power to the vehicle electrical appliances. At the same time, the second signal also undergoes amplification processing, is compared with the modulation signal, and a comparison signal is generated to control the battery unit to charge the supercapacitor unit. Finally, the modulation signal and the comparison signal are signal-integrated, and the integration signal generated based on the integration result is used to control the control unit to monitor the energy conversion between the battery unit and the supercapacitor unit in real time, ensuring the efficient and safe operation of the system.

[0050] The supercapacitor unit provides the necessary starting current for the engine at low temperatures, solving the problem of insufficient output capacity of traditional battery units at low temperatures. At the same time, the intelligent monitoring and signal processing of the control unit ensure the efficiency and safety during the energy conversion process. Especially through the meticulous processing and comparison of signals, overcharging and undercharging are prevented, extending the service life of the power supply device. In addition, the use of integrated signals enables the control unit to monitor the state and flow of energy in real time, further enhancing the stability of the system and the accuracy of power management, providing a more optimized low-temperature starting solution for the vehicle power system, and improving the problem of overcharging or undercharging that easily occurs during the energy conversion between the supercapacitor and the battery, thereby causing damage to the power supply device.

[0051] Embodiment 2:

[0052] In step S100, the external environment of the vehicle is detected by a preset temperature sensor to obtain temperature parameters.

[0053] By using a high-precision temperature sensor to collect external environment temperature data in real time, the collected temperature parameters are transmitted to the processing unit. Specifically, the sensor array covers different directions to obtain ambient temperatures at multiple points to ensure the accuracy and stability of the data.

[0054] For example, the temperature sensor can sample 10 times per second, and input the temperature data into an integrated temperature monitoring system for further processing.

[0055] The temperature parameters are non-linearly transformed using a multi-layer perceptron neural network to obtain a feature vector and a probability distribution. The feature vector is compared with the upper limit of a preset threshold using fuzzy logic to obtain a first comparison result, and the probability distribution is subjected to Bayesian inference with the lower limit of the preset threshold to obtain a second comparison result.

[0056] By inputting the temperature parameters into a multi-layer perceptron neural network for complex non-linear mapping, a feature vector and a probability distribution representing the current temperature environment are generated, and further analysis is based on this. Specifically, the feature vector and the upper limit threshold are compared through fuzzy logic operations to determine whether the low-temperature condition is met, while the probability distribution evaluates its fitness with the lower limit threshold through Bayesian inference to obtain the second comparison result.

[0057] For example, the neural network calculates the feature vector as [0.7, 0.3] and the probability distribution as 0.2, and a comparison conclusion is obtained after logical operations with the threshold.

[0058] A boundary result is generated based on the first comparison result and the second comparison result.

[0059] By combining the first comparison result and the second comparison result, a final determination result is generated through weighted averaging or other fusion strategies to reflect whether the current external environmental temperature reaches the condition for starting the decision-making. Specifically, logical operators are used to integrate the two comparison results to generate a single determination value for subsequent control decisions.

[0060] For example, if both comparison results indicate below the threshold, the determination result is "low temperature", and preparations are made to start the supercapacitor auxiliary system.

[0061] In step S200, based on the determination result, the control unit issues a pulse width modulation signal, and the adaptive gain control circuit amplifies and modulates the pulse width modulation signal to obtain an adjustment signal and a reference signal.

[0062] The determination result drives the control unit to generate a corresponding pulse width modulation signal, and the adaptive gain control circuit dynamically adjusts the signal amplitude to facilitate adaptive adjustment in combination with the actual load condition of the vehicle. Specifically, the circuit adjusts the gain according to the current load condition to ensure the efficiency and reliability of the output current.

[0063] For example, in the face of a large load, the gain control circuit automatically increases the amplitude of the pulse signal to achieve a 10% gain amplification.

[0064] The amplitude of the adjustment signal is adjusted by the feedback gain controller to obtain an adjusted signal, the adjusted signal is phase-synchronized with the reference signal to obtain a synchronization signal, and the supercapacitor unit is current-controlled based on the synchronization signal to provide starting current for the vehicle's engine.

[0065] After the feedback gain controller calculates the adjustment signal with the optimal amplitude, it is phase-aligned with the reference signal to generate a synchronization signal, ensuring the consistency and stability of the current waveform. Specifically, the synchronization signal is used to adjust the output current of the supercapacitor unit so that the starting current provided to the engine can precisely match its requirements.

[0066] For example, the synchronization signal can adjust the output current to reach 350A to ensure that the engine starting is not affected by the external temperature.

[0067] In step S300, the control signal is spectrally analyzed through Fourier transform to obtain spectral data, a frequency-domain signal is generated based on the spectral data, and the frequency-domain signal is decomposed by wavelet decomposition to obtain a low-frequency component.

[0068] Through Fourier transform, the control signal is converted from the time domain to the frequency domain to analyze its spectral characteristics. Specifically, the fast Fourier transform (FFT) is performed on the spectrum of the signal to obtain spectral data, and this data is reconstructed into a frequency-domain signal for further analysis. Subsequently, wavelet decomposition technology is applied to decompose the frequency-domain signal into multi-level band coefficients, and the low-frequency components for low-frequency analysis are separated out.

[0069] For example, if there are low-frequency components in the analyzed signal in the range of 0 - 100 Hz, wavelet decomposition extracts these low-frequency features for subsequent processing.

[0070] The amplitude calculation is performed on the low-frequency components according to the power spectral density to obtain amplitude data and phase data. The amplitude data is filtered and smoothed to obtain a smoothed signal, and the smoothed signal is inversely transformed using the low-frequency components to generate a first signal.

[0071] By calculating the power spectral density of the low-frequency components, the corresponding amplitude and phase data can be obtained. Specifically, the power spectral density function is used to quantify the energy characteristics of the signal, and the results are reflected in the amplitude data. After these data are processed by a smoothing filter, the high-frequency noise components are removed to ensure the authenticity of the signal during reconstruction. Then, the low-frequency components are used to perform an inverse transformation (such as inverse wavelet transform) on the smoothed signal, and finally a first signal for subsequent analysis is generated.

[0072] For example, low-pass filtering is performed on the low-frequency components to eliminate high-frequency noise, and then the signal becomes more stable and easier to process.

[0073] The phase tracking is performed on the first signal through a phase-locked loop circuit to obtain a phase signal and a frequency signal. A phase adjustment signal is generated based on the phase signal, and the frequency signal is weighted using the phase adjustment signal to obtain a second signal.

[0074] Precise phase tracking is performed on the first signal through a phase-locked loop circuit to obtain the phase signal and the frequency signal output by the loop. Specifically, the phase-locked loop circuit continuously adjusts the output phase to be synchronized with the input signal, thereby generating a phase signal. Subsequently, the phase signal is converted into a phase adjustment signal for weighting the frequency signal to ensure the stability and consistency of the frequency signal, and finally a more stable second signal is obtained.

[0075] For example, when a phase offset is detected, the phase-locked loop automatically adjusts the output to cancel the deviation, which ensures the stability of the system frequency.

[0076] In step S400, the first signal is denoised by a Kalman filter to obtain a base signal, a noise signal, and a deviation signal. Polynomial fitting is applied to decompose the characteristics of the base signal to obtain intrinsic mode functions and characteristic signals. The least mean square algorithm is used for the noise signal with the intrinsic mode functions to obtain a filtered signal.

[0077] The first signal is processed by a Kalman filter to effectively distinguish the base signal, the noise signal, and the deviation signal. Specifically, the Kalman filter estimates and adjusts the signal according to the signal dynamic model and the observed data to reduce the influence of noise. The polynomial fitting method is used for the base signal to decompose its characteristics to obtain the intrinsic mode functions and their corresponding characteristic signals. Furthermore, the intrinsic mode functions and the least mean square algorithm are applied to the noise signal for prediction and adjustment to generate a highly pure filtered signal.

[0078] For example, the Kalman filter can dynamically track the change of the signal state, adjust the noise in real time, and the optimized filtered signal retains the main characteristics of the signal.

[0079] The filtered signal and the control signal are dynamically and adaptively amplified by a fuzzy controller to obtain an amplified control signal.

[0080] By introducing a fuzzy controller, the filtered signal and the control signal are adaptively adjusted and amplified in real time. Specifically, the fuzzy controller uses the fuzzy set of the input signal and uses the rule base and the inference mechanism to perform dynamic adaptive processing on the two signals to optimize the output signal.

[0081] This method ensures that the amplified control signal has high steady-state performance and response speed when adapting to different load conditions.

[0082] For example, when the system load increases sharply, adaptive amplification is used to ensure sufficient power supply.

[0083] Phase modulation is applied to perform frequency vector transformation on the amplified control signal and the first amplified signal to obtain a vector signal and a phase signal. The vector signal is optimized by a phase compensator to obtain an optimized signal, and the optimized signal is mutually coupled by the phase signal to obtain a modulated signal.

[0084] By implementing phase modulation, the amplified control signal and the first amplified signal are converted into the frequency vector form to generate a vector signal and a phase signal. Specifically, the phase compensator is used to perform dynamic correction and optimization processing on the vector signal, and the phase difference is adjusted in a timely manner to improve the signal consistency and stability, and finally an optimized signal is formed. The optimized signal is accurately coupled by the phase signal, and finally a modulated signal is integrated.

[0085] For example, the phase-compensated vector signal not only reduces the phase error but also improves the quality of the final output signal.

[0086] In step S500, the second signal is separated by a harmonic analyzer to obtain a fundamental frequency signal, a harmonic signal, and a phase shift signal. Principal component analysis is applied to reduce the dimension of the fundamental frequency signal to obtain a principal component signal and a secondary component signal.

[0087] Through the harmonic analyzer, the second signal is accurately decomposed to extract its fundamental frequency signal, harmonic signal, and phase shift signal. Specifically, each signal component is extracted through spectral analysis for in-depth signal processing. The principal component analysis method is applied to reduce the dimension of the fundamental frequency signal to further uncover the main component features and form a signal model with optimized primary and secondary component structures.

[0088] For example, the obtained principal component signal represents 90% of the energy of the overall signal, greatly simplifying subsequent data signal processing.

[0089] The frequency of the principal component signal is verified using the fast Fourier transform to obtain a frequency signal. The windowing process is applied to the harmonic signal using the frequency signal to obtain a harmonic envelope. The trend of the secondary component signal is evaluated to obtain a trend signal. The trend signal and the frequency signal are combined to obtain a second amplified signal.

[0090] The frequency of the principal component signal is verified using the fast Fourier transform to confirm the signal spectrum characteristics. Specifically, a window function is applied to the harmonic signal to further enhance the frequency resolution of the signal to obtain a more accurate harmonic envelope. At the same time, the trend of the secondary component signal is analyzed to identify the change pattern and generate a trend signal. Combining the frequency and trend signals, a second amplified signal reflecting the dynamic changes of the signal is finally obtained.

[0091] For example, the windowed harmonic envelope provides more continuous response data for accurate filtering.

[0092] The second amplified signal and the modulation signal are co-analyzed to obtain a refined signal, a harmonic signal, and a differential signal. Cross-correlation processing is performed on the refined signal to generate a relative signal and an absolute signal. The relative signal and the harmonic signal are compensated to obtain a compensation signal. The absolute signal and the differential signal are integrated to obtain a redundant signal.

[0093] By jointly analyzing the second amplified signal and the modulation signal, fine signal parsing is performed to distinguish refined signals, cooperative harmonic signals, and differential information. Specifically, through signal cross-correlation processing technology, relative signals and absolute signals reflecting the relationship between signals are extracted and generated. A compensation operation is performed on the relative signal based on the harmonic signal to generate a compensation signal. At the same time, the characteristic components of the absolute signal and the differential signal are integrated to automatically generate redundant signals, improving the tolerance and robustness of the signals.

[0094] For example, signal compensation achieves a 15% reduction in jitter, while the redundant signal amplifies the visibility of important signal features.

[0095] Logical transformations are performed on the compensation signal and the redundant signal to obtain a comparison result, and a comparison signal is generated based on the comparison result.

[0096] By performing logical transformations on the compensation signal and the redundant signal, key information between data is captured and a clear comparison result is generated. Specifically, the signal logic processing module automatically generates a comparison signal for further control using a predefined logic framework.

[0097] For example, when the consistency between the compensation signal and the redundant signal is lower than a certain threshold, a high-sensitivity and high-precision abnormal alarm signal is generated through logical judgment.

[0098] In step S600, the modulation signal and the comparison signal are signal-integrated through an adaptive filtering algorithm to obtain an integration result.

[0099] The modulation signal and the comparison signal are processed through adaptive filter technology to finally form a comprehensive integration result. Specifically, by adjusting the filtering parameters and strategies, the goal of maximizing the signal correlation commonality and reducing the display of heterogeneity is achieved to promote the generation of a better mixed signal.

[0100] For example, adaptive filtering can dynamically respond to changes in the input signal, achieve a significant reduction in overall error information, and achieve a smooth mixed signal processing ability.

[0101] Fuzzy clustering analysis is used to classify the integration result data to obtain consistent signals, differential signals, and domain signals. The consistent signals are screened through a support vector machine model to obtain screened signals and standby signals.

[0102] The integration result signal is accurately classified through a fuzzy clustering analysis framework to identify consistent signals, differential signals, and other domain-specific signals. Specifically, the support vector machine technology is applied to the consistent signals for selection, deleting unnecessary information data, and finally extracting the standby screened signals and standby signals.

[0103] For example, through cluster analysis, the key signal characteristics around the changes are revealed to assist in decision-making and precise regulation of the system.

[0104] The differential signals are cluster-verified using the screening signals to obtain verification signals, and the domain signals are weighted-adjusted using the spare signals to obtain weighted signals.

[0105] Based on the screening signals, clustering operations are continued on the differential signals and correlation verification is performed to obtain evaluation signals of the signal population state. Specifically, the spare signals are referenced for the domain signals, and incremental adjustment is performed through a bias strategy to enable the optimized trade-off of the corrected signal group and output weighted signals.

[0106] Through the weight strategy plus cluster verification, stable algorithm performance improvement can be provided under different signal conditions.

[0107] The verification signals and weighted signals are correlation-analyzed using a neural network to obtain correlation signals.

[0108] By applying a deep neural network model to implement the interactive analysis process of the verification signals and weighted signals, a correlation data set that truly reflects the dynamic signal relationship is finally generated. Specifically, the network utilizes its multi-layer architecture and non-linear continuous mapping characteristics to strengthen the role perception and overall close cooperation measurement between signals, bringing the technical ability to cleverly generate correlation signals. As an instantiated feature, correlation analysis describes the energy flow at different energy unit positions in the entire system and provides a reference for subsequent authoritative control decisions.

[0109] The state of the battery unit and the supercapacitor unit is detected based on the correlation signals, and dynamic power management and real-time feedback control are performed to achieve real-time monitoring of energy conversion.

[0110] By importing the correlation signals into the energy management system for the health state monitoring of the battery unit and the supercapacitor unit, and accordingly promoting the combined application of energy efficiency control and feedback mechanisms. Specifically, power distribution management is implemented through dynamic prediction means to ensure operation consistency, efficiency, and safety, achieve efficient energy rationing, and construct a dynamic iterative control model through the precise expression of load and time window. In intelligent feedback, precise event detection protects the use of power resources, achieving the full coverage and optimization goal of refined monitoring of energy conversion. So that the system can effectively detect low power states and promptly initiate loop correction.

[0111] In this embodiment, the frequency-domain characteristics of the control signal are analyzed in detail through the application of Fourier transform. Wavelet decomposition further separates and refines the significant low-frequency components, making it more suitable for the needs of real-time systems. The Kalman filter plays a significant role in the decomposition of noise signals, ensuring that the generated filtered signal has high purity and stability characteristics. At the same time, the fuzzy controller adaptively amplifies the signal, providing deep adaptability to the dynamic changes in vehicle load. Harmonic analysis and principal component analysis techniques refine the harmonic characteristics, reduce signal bandwidth occupation, and improve frequency resolution. In the processing of the total output signal, phase compensation and frequency vector conversion techniques are used to achieve effective modulation of the signal. The obtained modulated signal undergoes rigorous pattern verification, and the final signal synthesis optimization and processing are performed through logical and adaptive analysis. In particular, the introduction of fuzzy clustering and support vector machines realizes the deep classification of data and weakens the redundant characteristics, providing strong technical support for the efficient transmission and feedback control of signals. Finally, through the dynamic power management and intelligent correlation analysis throughout the entire process, the efficacy and adaptability of the energy conversion system are comprehensively optimized, ensuring high-reliability startup at low temperatures and comprehensive dynamic power management.
