Description

Technical Field

[0001] The present invention relates to the technical field of mobile power supplies, and in particular to a battery protection system for a mobile power supply and the mobile power supply. Background Art

[0002] With the popularity of portable electronic devices, mobile power banks have become an indispensable daily necessity for modern people. According to statistics, the global mobile power bank market size will exceed US$20 billion in 2023, with an annual growth rate of more than 15%. However, behind this rapid development, safety issues such as lithium battery overcharging, over-discharging, and short circuits have always plagued the industry. Existing protection solutions mostly use the traditional voltage-current dual-threshold protection mechanism, which has problems such as response delays and false operation when dealing with complex usage scenarios. In particular, the popularization of fast charging technology in recent years (such as the PD3.0 / QC5.0 protocol) has made the battery operating environment more stringent, and traditional protection systems can no longer meet the safety requirements under high-power dynamic regulation.

[0003] Prior art 1, application number: CN202410656060.2 discloses a small-volume mobile power stack structure, including a battery display, a battery panel is provided at the bottom of the battery panel, a DC panel is provided at the bottom of the battery panel, a DC main panel is provided at the bottom of the DC panel, an image memory and an LED display are provided inside the battery display, a toroidal inductor is provided in the middle of one side of the DC panel, a solid-state capacitor is provided at one end of the toroidal inductor and on one side of the DC panel, and the DC panel includes a battery protection circuit. Although the structure achieves efficient space utilization by stacking the battery display, battery panel, DC panel and DC main panel, allowing the mobile power supply to integrate more functions while maintaining a small size, and adding user interaction functions through the image memory and LED display, allowing users to more intuitively understand the battery status and other information; however, it only relies on the traditional lithium battery protection panel for basic overcharge / discharge protection and lacks a pre-check mechanism when the load is connected.

[0004] Prior art 2, application number: CN202411322252.6 discloses a protocol level control circuit and a mobile power supply thereof, including a lithium battery protection module, a DC-DC module, an interface module and a discharge module; the voltage input ends of the lithium battery protection module and the DC-DC module are both connected to the positive pole of the lithium battery, the voltage output end of the DC-DC module is connected to the interface module, and the protocol end of the DC-DC module is connected to the protocol end of the interface module; the voltage input end of the discharge module is connected to the positive pole of the lithium battery, and the voltage output end of the discharge module is connected to the negative pole of the lithium battery and the ground respectively. Although a discharge module is set in the protocol level control circuit, when the lithium battery protection module triggers the power-off protection, the virtual electricity inside the lithium battery protection mechanism will be divided by the discharge module to lower the voltage between the positive and negative electrodes of the lithium battery, so that the system protocol is converted to charging mode at a low potential, effectively solving the problem of the battery cell being unable to charge after over-discharge or short-circuit testing; however, its protection action is based on a fixed threshold trigger (such as voltage / current exceeding the limit), and it is impossible to calculate the composite safety index in real time (such as a dynamic threshold combining temperature drift and cyclic attenuation coefficient), resulting in a risk of delayed protection response.

[0005] Prior art three, application number: CN202410512834.4, discloses an outdoor mobile power supply with non-interference AC and DC power. The power supply includes a housing, a solar charging panel, a front cover, a PCB, a battery pack with a lithium battery protection board, an LCD display, a DC button, an AC button, an LED light, a Type-C bidirectional fast charging port, a USB fast charging port, a DC port, a DC charging port, a rear cover, an inverter, an AC outlet, a fan, and a heat sink. When the DC port is operating, the inverter is controlled by a button, the AC outlet transmits AC power, and the battery pack with a lithium battery protection board limits the output power. When the total power of the load is overloaded, the output of the DC port is shut down. The DC and AC power do not interfere with each other. Although it can provide DC and AC power simultaneously to meet the needs of various devices, the non-interference between DC and AC effectively improves the user experience and efficiency. The LCD display is intuitive and visual, making it easier and faster to understand the charging or power supply status and make appropriate adjustments. However, directly switching from a static state to a working state may cause a transient impact, and there is a lack of secondary verification after the abnormality is recovered.

[0006] Currently, the existing technologies 1, 2 and 3 have the problem of insufficient safety control over the entire life cycle of the mobile power supply. Therefore, the present invention provides a battery protection system for a mobile power supply and a mobile power supply. Summary of the Invention

[0007] In order to solve the above technical problems, the present invention provides a battery protection system for a mobile power supply, comprising:

[0008] The first switching component is configured to obtain a load status of the mobile power supply and switch the mobile power supply between a static state and a working state according to the load status; when switching from the static state to the working state, the ready state is triggered to calculate an internal safety index of the mobile power supply and obtain an internal safety index result;

[0009] A second switching component is configured to compare the internal safety index with a safety threshold preset by the mobile power supply, and determine whether the mobile power supply is triggered from the ready state to the working state based on the comparison result; when the internal safety index is less than the safety threshold preset by the mobile power supply, the ready state is allowed to switch to the working state;

[0010] The third switching component is used to monitor the internal safety index of the working state in real time. When the internal safety index is not less than the preset safety threshold of the mobile power supply, the safety state is triggered, an early warning is issued, the working state is stopped, and the state is switched to the static state.

[0011] Optionally, the first switching component includes:

[0012] The dynamic parameter set capture module is used to activate the multi-dimensional parameter acquisition network when the first switching component triggers the ready state. It obtains the static parameter set stored by the mobile power supply during the static state through the cross-sensing channel, including three core parameters: energy carrier stability, interface potential residual amount, and dielectric structure deformation accumulation value. At the same time, the dynamic scanning module is activated to collect the energy fluctuation trajectory and state transition rate generated at the moment of current load connection at a preset frequency to obtain dynamic scanning data.

When the load access characteristic is detected as sudden, a positive compensation weight is applied to the dynamic balance coefficient; if it is gradual, the negative compensation mechanism of the structural stress index is activated. The compensated dual parameters are vector-synthesized in the normalization processing unit to output the initial safety value.

[0015] The dynamic threshold calibration module is used to input the initial safety value into the adaptive threshold space of the mobile power supply. The adaptive threshold space dynamically adjusts the comparison benchmark according to the historical working mode database; the difference calculation between the calibrated dynamic threshold and the initial safety value is performed to obtain the final internal safety index.

[0017] Optionally, in the dynamic threshold calibration module, when a high-temperature operation record is detected in the previous working cycle, the baseline value is shifted downward according to a preset curve; if multiple consecutive short-term charging and discharging are monitored, the baseline value increment program is activated.

[0020] Hierarchical attenuation topology generation submodule, used to construct a hierarchical processing channel consisting of a primary attenuation layer, a secondary attenuation layer, and a dynamic feedback loop on the basic matrix;

[0021] The stress index synthesis submodule is used to pass the hierarchically attenuated data into a multi-channel fusion unit containing longitudinal stress components, transverse stress components, and time-space coupling operations.

[0022] Optional, longitudinal stress component of the stress index synthesis submodule: extract the interface potential residual after the primary attenuation layer is processed, associate it with the current load access characteristics, and if it is a sudden load, superimpose the residual fluctuation component of the residual;

[0023] Transverse stress component: Extract the maximum deformation gradient value and its spatial distribution density from the deformation energy distribution map output by the secondary attenuation layer, and perform normalization correction based on the historical deformation recovery rate of the dielectric structure;

[0024] Spatiotemporal coupling operation: The longitudinal and transverse components are vector-superimposed in the weight space defined by the rate mapping layer. In the superposition process, invalid noise data caused by hierarchical attenuation are automatically eliminated, and the final output is a structural stress index with spatiotemporal continuity.

[0025] Optional, dynamic threshold calibration module, including:

[0026] The threshold activation preprocessing submodule is used to superimpose the baseline value output by the adaptive threshold space with the high-temperature offset curve and short-time charge and discharge incremental records in the historical operating mode database to generate an activation threshold with time-decay characteristics. It also activates the corresponding threshold compensation factor based on the load access feature type captured by the current dynamic scanning module.

[0027] The difference space construction submodule is used to establish the mapping relationship between the initial safety value and the activity threshold in the normalized dimensional space;

[0028] Dynamic difference core operation submodule, used to perform multi-dimensional difference analysis between activity threshold and initial safety value;

[0029] The safety index reconstruction submodule is used to convert multi-channel difference results into quantifiable evaluation values.

[0030] Optionally, the second switching component includes:

[0031] a threshold dynamic adjustment module, configured to activate a threshold adaptive engine before the second switching component receives the internal safety index;

[0032] A dual-modal comparison module is used to establish a dual interactive channel between the internal security index and the dynamic adjustment threshold;

[0033] A transition state processing module is used to perform a smooth state transition before switching from the ready state to the working state;

[0034] The decision condition generation module is used to switch the permission signal between the synthesis states based on the comparison results.

[0035] Optional decision condition generation module, including:

[0036] The multidimensional data field construction submodule is used to construct a risk analysis basis based on the output results of the bimodal comparison module;

[0037] The safety margin fusion submodule is used to introduce the safety margin component buffer pool data in the difference operation stage;

[0038] Gradient vector synthesis submodule, used to extract dynamic gradients from the fused multi-dimensional data field;

[0039] The risk level division submodule is used to convert the synthetic gradient vector into a quantifiable risk level; detect the abnormal section where the gradient vector direction continuously deviates from the phase reference axis, and divide the structural fatigue risk zone based on the change trend of the second-order derivative of the cumulative value of the medium structure deformation.

[0040] The present invention provides a mobile power supply, which includes: a shell, an interface, an indicator light, a battery and a controller; the shell is provided with the interface and the indicator light, the shell is internally installed with a battery and a controller, and the controller stores programs of a first switching component, a second switching component and a third switching component.

[0041] The present invention realizes the safe closed-loop management of the working state of the mobile power supply through the coordinated operation of three-level switching components. The state hierarchical control realizes the basic switching between the static state and the working state through the first switching component, and adds the ready state as an intermediate transition state. In the ready state stage, the internal safety assessment (such as the composite calculation of parameters such as temperature, voltage, and current) is completed to ensure that only mobile power supplies that pass the initial safety test can enter the working state. The second switching component of the threshold pre-check mechanism forms a secondary check at the hardware level by comparing the real-time calculated safety index with the preset threshold (such as hardware protection parameters such as overcharge / discharge voltage and maximum temperature rise); it can intercept abnormal situations where the safety index exceeds the limit and prevent potential risk equipment from entering the work process. The third switching component of dynamic safety protection performs real-time monitoring during the continuous operation of the working state. When an abnormal safety index is detected (such as battery pack balancing failure or instantaneous overload), a protective shutdown is triggered immediately. Dynamic monitoring expands the function of the traditional protection circuit to form a software-configurable flexible protection strategy.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0052] Example 1: Figure 1 As shown, an embodiment of the present invention provides a battery protection system for a mobile power supply, comprising:

[0053] The first switching component is configured to obtain a load status of the mobile power supply and switch the mobile power supply between a static state and a working state according to the load status; when switching from the static state to the working state, the ready state is triggered to calculate an internal safety index of the mobile power supply and obtain an internal safety index result;

[0054] A second switching component is configured to compare the internal safety index with a safety threshold preset by the mobile power supply, and determine whether the mobile power supply is triggered from the ready state to the working state based on the comparison result; when the internal safety index is less than the safety threshold preset by the mobile power supply, the ready state is allowed to switch to the working state;

[0055] The third switching component is used to monitor the internal safety index of the working state in real time. When the internal safety index is not less than the preset safety threshold of the mobile power supply, the safety state is triggered, an early warning is issued, the working state is stopped, and the state is switched to the static state.

[0056] The working principle and beneficial effects of the above technical solution are as follows: The first switching component of this embodiment is used to obtain the load status of the mobile power supply and switch the mobile power supply between the quiescent state and the working state based on the load status. When switching from the quiescent state to the working state, the ready state is triggered, and the internal safety index of the mobile power supply is calculated to obtain the internal safety index result. The second switching component is used to compare the internal safety index with the preset safety threshold of the mobile power supply and, based on the comparison result, determine whether the mobile power supply has been triggered from the ready state to the working state. When the internal safety index is less than the preset safety threshold of the mobile power supply, the ready state is allowed to switch to the working state. The third switching component is used to monitor the internal safety index of the working state in real time. When the internal safety index is not less than the preset safety threshold of the mobile power supply, the safe state is triggered, an alarm is issued, the working state is stopped, and the mobile power supply is switched to the quiescent state. This embodiment achieves a safe closed-loop management of the working state of the mobile power supply through the coordinated operation of three switching components. The state hierarchical control uses the first switching component to achieve the basic switching between the quiescent state and the working state, and adds the ready state as an intermediate transition state. The internal safety assessment is completed in the ready state stage, ensuring that only mobile power supplies that pass the initial safety test can enter the working state. The threshold pre-check mechanism's second switching component compares the real-time calculated safety index with a preset threshold, providing a secondary hardware-level check. This prevents abnormalities in safety indexes exceeding limits, preventing potentially risky equipment from entering the process. The dynamic safety protection third switching component performs real-time monitoring during continuous operation. If an abnormal safety index is detected, it immediately triggers a protective shutdown. This dynamic monitoring expands the capabilities of traditional protection circuits, creating a flexible, software-configurable protection strategy.

[0057] This embodiment establishes a three-stage protection system: pre-check, execution, and monitoring. During the static phase (resting state), power output is cut off; during the startup phase (ready state), safety self-checks are completed; and during the dynamic phase (operating state), real-time protection is maintained. Ultimately, multi-level safety protection is achieved throughout the entire working cycle of the mobile power supply. Its technical characteristics are reflected in the combined application of conditional judgment and threshold control for state switching.

[0058] Example 2: Figure 2 As shown, based on Example 1, the first switching component provided by this embodiment of the present invention includes:

[0059] The dynamic parameter set capture module is used to activate the multi-dimensional parameter acquisition network when the first switching component triggers the ready state. It obtains the static parameter set stored by the mobile power supply during the static state through the cross-sensing channel, including three core parameters: energy carrier stability, interface potential residual amount, and dielectric structure deformation accumulation value. At the same time, the dynamic scanning module is activated to collect the energy fluctuation trajectory and state transition rate generated at the moment of current load connection at a preset frequency to obtain dynamic scanning data.

[0060] The parameter fusion and feature evolution module is used to input the static parameter set and dynamic scanning data into a two-layer fusion architecture. The first layer performs waveform matching analysis on the energy carrier stability and energy fluctuation trajectory to generate a dynamic balance coefficient. The second layer establishes a correlation matrix between the interface potential residual and the accumulated value of the dielectric structure deformation and the state transition rate, and calculates the structural stress index through a hierarchical attenuation algorithm.

[0061] The initial safety value generation module is used to enter the dynamic balance coefficient and structural stress index into the nonlinear compensation channel. When the load access characteristic is detected as sudden, a positive compensation weight is applied to the dynamic balance coefficient; if it is gradual, the negative compensation mechanism of the structural stress index is activated. The compensated dual parameters are vector-synthesized in the normalization processing unit to output the initial safety value.

[0062] The dynamic threshold calibration module is used to input the initial safety value into the adaptive threshold space of the mobile power supply. The adaptive threshold space dynamically adjusts the comparison benchmark based on the historical working mode database: when a high-temperature operation record is detected in the previous working cycle, the benchmark value is shifted downward according to the preset curve; if multiple consecutive short-term charging and discharging are monitored, the benchmark value increment program is activated; the calibrated dynamic threshold is subtracted from the initial safety value to obtain the final internal safety index.

[0063] The working principle and beneficial effects of the above technical solution are as follows: the dynamic parameter set capture module of this embodiment is used to start the multi-dimensional parameter acquisition network when the first switching component triggers the ready state, and obtain the static parameter set stored by the mobile power supply during the static state through the cross-sensing channel, including three core parameters: energy carrier stability, interface potential residual and dielectric structure deformation cumulative value; at the same time, the dynamic scanning module is activated to collect the energy fluctuation trajectory and state transition rate generated at the moment of current load access at a preset frequency to obtain dynamic scanning data; the parameter fusion and feature evolution module is used to input the static parameter set and dynamic scanning data into a two-layer fusion architecture: the first layer performs waveform matching analysis on the energy carrier stability and energy fluctuation trajectory to generate a dynamic balance coefficient; the second layer establishes a correlation matrix between the interface potential residual and the dielectric structure deformation cumulative value and the state transition rate respectively, through The structural stress index is calculated through a hierarchical attenuation algorithm; the initial safety value generation module is used to enter the dynamic balance coefficient and the structural stress index into a nonlinear compensation channel. When the load access characteristic is detected to be a mutation type, a positive compensation weight is applied to the dynamic balance coefficient; if it is a gradual type, the negative compensation mechanism of the structural stress index is activated; the compensated dual parameters are vector-synthesized in the normalization processing unit to output the initial safety value; the dynamic threshold calibration module is used to input the initial safety value into the adaptive threshold space of the mobile power supply, and the adaptive threshold space dynamically adjusts the comparison benchmark according to the historical working mode database: when a high-temperature operation record is detected in the previous working cycle, the benchmark value is shifted downward according to the preset curve; if multiple consecutive short-term charging and discharging are monitored, the benchmark value increment program is activated; the calibrated dynamic threshold is differenced with the initial safety value to obtain the final internal safety index.

[0064] Example 3: Based on Example 2, the parameter fusion and feature evolution module provided in this embodiment of the present invention includes:

[0065] The correlation matrix construction submodule is used to establish a three-dimensional correlation field based on the residual interface potential, the cumulative value of the dielectric structure deformation, and the state transition rate;

[0066] Vertical dimension: The interface potential residual is divided into multiple discrete intervals according to the historical static time, and each interval corresponds to the gradient attenuation mode of the residual;

[0067] Horizontal dimension: Generate deformation energy distribution map based on the growth trend of the cumulative value of medium structure deformation;

[0068] Rate mapping layer: The state transition rate is used as a dynamic weight factor and injected into the intersection nodes of the vertical and horizontal dimensions to form a basic matrix that contains spatiotemporal correlation characteristics;

[0069] Hierarchical attenuation topology generation submodule, used to construct a hierarchical processing channel consisting of a primary attenuation layer, a secondary attenuation layer, and a dynamic feedback loop on the basic matrix;

[0070] Primary attenuation layer: applies rate-dependent attenuation to the interface potential residue in the longitudinal dimension. When the state transition rate exceeds a critical value, the exponential attenuation function of the residue is activated to reduce its cumulative contribution to the structural stress.

[0071] Secondary attenuation layer: In the lateral dimension, a selective attenuation strategy is adopted based on the dense regional characteristics of the deformation energy distribution map. Linear attenuation is applied to areas exceeding the deformation threshold, while areas within the threshold are retained at the original value.

[0072] Dynamic feedback loop: The output of the primary attenuation layer is used as the input reference of the secondary attenuation layer, and the real-time change of the state transition rate is fed back to the attenuation coefficient regulator to form a closed-loop control link;

[0073] The stress index synthesis submodule is used to pass the hierarchically attenuated data into a multi-channel fusion unit containing longitudinal stress components, transverse stress components, and time-space coupling operations;

[0074] Longitudinal stress component: Extract the residual interface potential after the primary attenuation layer is processed and correlate it with the current load access characteristics. If it is a sudden load, the residual fluctuation component of the residual is superimposed;

[0075] Transverse stress component: Extract the maximum deformation gradient value and its spatial distribution density from the deformation energy distribution map output by the secondary attenuation layer, and perform normalization correction based on the historical deformation recovery rate of the dielectric structure;

[0076] Spatiotemporal coupling operation: The longitudinal and transverse components are vector-superimposed in the weight space defined by the rate mapping layer. In the superposition process, invalid noise data caused by hierarchical attenuation are automatically eliminated, and the final output is a structural stress index with spatiotemporal continuity.

[0077] The working principle and beneficial effects of the above technical solution are as follows: the correlation matrix construction submodule of this embodiment is used to establish a three-dimensional correlation field based on the residual interface potential, the cumulative value of the dielectric structure deformation and the state transition rate; the hierarchical attenuation topology generation submodule is used to construct a hierarchical processing channel including a primary attenuation layer, a secondary attenuation layer and a dynamic feedback loop on the basic matrix; the stress index synthesis submodule is used to enter the multi-channel fusion unit including the longitudinal stress component, the transverse stress component and the time-space coupling operation through the data after hierarchical attenuation. This embodiment realizes the accurate quantitative evaluation of the structural stress state through multi-dimensional data processing and dynamic feedback mechanism. The precise construction of the spatiotemporal correlation field establishes a basic data field that contains both static historical accumulation effects and dynamic real-time change characteristics through the three-dimensional correlation of the interface potential residual (longitudinal), the cumulative value of the dielectric deformation (transverse) and the state transition rate (dynamic weight); the correlation matrix construction submodule converts the originally discrete physical quantity parameters into a structured expression with spatiotemporal continuity. Hierarchical stress attenuation control. The hierarchical attenuation topology generation submodule achieves dynamic reduction of historical residual stresses (preventing overload accumulation), regionalized regulation of local deformation energy (avoiding stress concentration), and maintains the stability of the attenuation process through a dynamic feedback loop (real-time adjustment of the attenuation coefficient) through a cascade of a primary attenuation layer (rate-dependent exponential attenuation) and a secondary attenuation layer (deformation threshold selective attenuation). Multi-source stress fusion assessment. The stress index synthesis submodule uses a longitudinal component to capture residual potential fluctuations during sudden load changes, a transverse component to quantify deformation gradients and spatial distribution density, and a spatiotemporal coupling operation to eliminate noise introduced by hierarchical attenuation. The final output structural stress index combines attenuation correction for historical cumulative effects, density weighting of spatial distribution characteristics, and real-time coupling of dynamic transition rates. This mechanism achieves dynamic decoupling and precise quantification of structural stress states under complex working conditions, providing a highly reliable fusion feature indicator for subsequent stress warning or control decisions.

[0078] Example 4: Based on Example 2, the dynamic threshold calibration module provided by the embodiment of the present invention includes:

[0079] The threshold activation preprocessing submodule is used to superimpose the baseline value output by the adaptive threshold space with the high-temperature offset curve and short-time charge and discharge incremental records in the historical operating mode database to generate an activity threshold with time-attenuation characteristics. Based on the load access feature type (sudden / progressive) captured by the current dynamic scanning module, the corresponding threshold compensation factor is activated. Sudden loads trigger the threshold boundary expansion mechanism, allowing the activity threshold to elastically expand within a preset range; progressive loads activate the threshold density enhancement algorithm.

[0080] The difference space construction submodule is used to establish the mapping relationship between the initial safety value and the activity threshold in the normalized dimensional space;

[0081] Axial alignment: Phase-match the vector direction of the initial safety value with the reference axis of the activity threshold to eliminate dimensional deviations caused by different parameter sources. During the matching process, the fluctuation characteristics of the initial safety value dominated by the dynamic balance coefficient are prioritized.

[0082] Weight field generation: Based on the structural stress index output by the parameter fusion and feature evolution module, a gradient weight distribution field is formed in the difference space. The area with higher stress index corresponds to the nonlinear enhancement area of the weight field, so that the difference calculation results in this interval have an amplified effect.

[0083] Dynamic difference core operation submodule, used to perform multi-dimensional difference analysis between activity threshold and initial safety value;

[0084] Main difference channel: Calculate the vertical distance between the endpoint of the initial safety value vector and the active threshold reference plane as the basic difference; retain the waveform characteristics of the dynamic balance coefficient and the spatial distribution information of the structural stress index;

[0085] Secondary compensation channel: The residual component of the structural stress index generated by the hierarchical attenuation algorithm that is not covered by the normalization processing unit is injected into the correction loop of the difference operation; when a sudden inflection point of the cumulative value of the medium structure deformation is detected, the instantaneous compensation mechanism of the difference amount is activated;

[0086] Boundary convergence control: Utilizes the historical pattern recognition capabilities of the adaptive threshold space to gradually converge the difference results that exceed the preset fluctuation range. The convergence strength is positively correlated with the number of consecutive short-term charge and discharge times, forming an error suppression link with self-learning characteristics.

[0087] The safety index reconstruction submodule is used to convert the multi-channel difference results into quantifiable evaluation values;

[0088] Polarity separation processing: The basic difference is split into an overload risk component and a safety margin component according to positive and negative polarity. The overload risk component directly participates in index synthesis, while the safety margin component enters the buffer pool to offset instantaneous fluctuations in subsequent working cycles;

[0089] Spatiotemporal energy integration: Energy accumulation calculation is performed on the difference value after the weight field is enhanced. The integration interval covers the entire cycle from the static state to the current working state. During the integration process, the decay curve of the interface potential residual is introduced as the time weight factor, so that the influence of the historical static state gradually weakens over the working time.

[0090] Index packaging: The integration result is secondarily coupled with the reference offset of the dynamic threshold calibration module. The final output value includes a composite safety index of real-time load impact strength, long-term structural deformation trend, and residual effects of historical working modes.

[0091] The working principle and beneficial effects of the above technical solution are as follows: The threshold activation preprocessing submodule of this embodiment is used to superimpose the baseline value output by the adaptive threshold space with the high-temperature offset curve and short-time charge and discharge incremental records in the historical operating mode database to generate an activity threshold with time-decay characteristics; based on the load access feature type (sudden / progressive) captured by the current dynamic scanning module, the corresponding threshold compensation factor is activated; sudden loads trigger the threshold boundary expansion mechanism, elastically expanding the activity threshold within a preset range; progressive loads activate the threshold density enhancement algorithm; the difference space construction submodule is used to establish a mapping relationship between the initial safety value and the activity threshold in the normalized dimensional space; the dynamic difference core operation submodule is used to perform multi-dimensional difference analysis between the activity threshold and the initial safety value; and the safety index reconstruction submodule is used to convert the multi-channel difference results into a quantifiable assessment value. Through the interaction between the activation threshold and the dynamic difference space, this embodiment ensures that the final safety index not only reflects the instantaneous difference between the current parameters and the baseline, but also includes the state evolution law throughout the life cycle of the mobile power supply. The gradient distribution and boundary convergence control of the weight field form a double protection against sudden interference, and the polarity separation processing achieves a precise balance between risk warning and safety redundancy.

[0092] Example 5: Figure 3 As shown, based on Example 1, the second switching component provided by this embodiment of the present invention includes:

[0093] a threshold dynamic adjustment module, configured to activate a threshold adaptive engine before the second switching component receives the internal safety index;

[0094] Historical mode loading: Extract the high-temperature operation cumulative duration and short-time charge and discharge frequency parameters from the mobile power supply's historical operating mode database to generate a baseline threshold correction vector. If it is detected that there were more than three consecutive short-time charges and discharges in the previous operating cycle, the vector direction points to the threshold weakening domain.

[0095] Load feature binding: Combined with the load access type (sudden / progressive) captured by the first switching component, a dynamic bias is applied to the baseline threshold. Sudden loads trigger threshold surface expansion, extending the safety margin outward; progressive loads activate threshold density compression, improving comparison accuracy.

[0096] A dual-modal comparison module is used to establish a dual interactive channel between the internal security index and the dynamic adjustment threshold;

[0097] Main comparison channel: Maps the security index to the main evaluation plane of the threshold space and calculates its Euclidean distance to the current threshold. The dynamic balance coefficient waveform characteristics output by the initial security value generation module are retained as the phase correction factor for distance calculation.

[0098] Auxiliary comparison channel: Extracts the transverse stress component from the structural stress index generated by the hierarchical attenuation algorithm and constructs a three-dimensional comparison auxiliary surface. When the spatial distribution density of the cumulative value of the medium structure deformation exceeds a critical value, the auxiliary surface automatically tilts to change the distance calculation result of the main channel.

[0099] A decision condition generation module is used to switch the permission signal between the synthesis states through comparison results;

[0100] Risk gradient field construction: Based on the Euclidean distance output by the main comparison channel, the safety margin component buffer pool data from the difference operation stage is superimposed to generate a risk gradient map. The high gradient areas in the risk gradient map correspond to the instantaneous overload risk caused by sudden load changes.

[0101] Permit signal encoding: When the global value of the risk gradient field is lower than the dynamic adjustment threshold, the spatiotemporal coupling calculation result of the structural stress index is converted into a binary permission code. If an abnormal attenuation of the interface potential residual is detected during the code generation process, a delay check bit is inserted.

[0102] Load compatibility verification: Use dynamic parameter sets to capture the energy fluctuation trajectory stored in the module and reconstruct the virtual load model. Input the licensed code into the model for reverse compatibility testing to verify its stability tolerance under sudden load shocks.

[0103] The transition state processing module is used to perform a smooth state transition before switching from the ready state to the working state:

[0104] Exponential residual removal: Activate the release loop of the interface potential residual accumulated during the static state, and reduce the residual amount to less than 10% of the corresponding range of the safety threshold through a controllable attenuation channel;

[0105] Balance coefficient latch: applies transient freezing processing to the dynamic balance coefficient to maintain waveform integrity during the switching process and avoid parameter distortion caused by state transition;

[0106] Stress preloading: Based on the structural stress index prediction model, a reverse deformation compensation force field is applied to the medium structure to offset the instantaneous stress increment caused by the upcoming load impact.

The decision-making process of this embodiment realizes a three-dimensional assessment of the risk field through a dual comparison channel, combined with the forward-looking compensation mechanism of the transition state processing stage, to ensure that the inter-state switching not only meets the real-time safety requirements, but also establishes a stable parameter base for the working state. The dynamic adjustment of the threshold is bound to the load characteristics to form an adaptive decision boundary.

[0110] Main gradient basis: The Euclidean distance data calculated by the main comparison channel is mapped to a three-dimensional spatial coordinate system, and the dynamic balance coefficient waveform characteristics are used as the phase reference axis of the coordinate system to form a basic gradient field with waveform synchronization characteristics;

[0111] Auxiliary stress layer superposition: Extract the three-dimensional comparison auxiliary surface data generated by the auxiliary comparison channel, convert its transverse stress component into a stress gradient vector, and inject it into the corresponding node of the basic gradient field according to the spatial density distribution; when the spatial density of the cumulative value of the medium structure deformation exceeds the critical mark, the vector direction deflection mechanism is triggered, forming stress interference lines;

[0112] The safety margin fusion submodule is used to introduce the safety margin component buffer pool data in the difference operation stage;

Sudden loads trigger the rapid release of the safety margin component in the pool, forming a protective film layer covering the basic gradient field; progressive loads activate the layered penetration mode, allowing the margin component to gradually merge with the gradient field.

[0114] Field strength correction: The released margin component is converted into a field strength correction coefficient to locally attenuate high-risk areas dominated by Euclidean distance in the basic gradient field. The waveform phase information of the dynamic balance coefficient is retained during the correction process to ensure that the spatiotemporal continuity of the gradient field is not destroyed.

[0115] Gradient vector synthesis submodule, used to extract dynamic gradients from the fused multi-dimensional data field;

[0116] Main gradient vector extraction: Capture the gradient vector with the maximum Euclidean distance change rate along the phase reference axis of the basic gradient field. The vector strength is negatively correlated with the baseline offset of the dynamic threshold calibration module; the larger the offset, the higher the vector attenuation coefficient.

[0117] Stress gradient coupling: The gradient vector of the auxiliary stress layer is orthogonally synthesized with the main gradient vector. The synthesis angle depends on the current decay rate of the interface potential residue. When the residue is lower than the standard value of the static parameter set, the acute angle coupling mode is enabled to enhance the risk identification sensitivity.

This embodiment uses the stacked fusion of multi-dimensional data fields and the dynamic synthesis of gradient vectors to enable the risk gradient map to reflect the real-time load impact intensity and capture the long-term structural deformation trend. The orthogonal coupling mechanism of the main gradient base and the auxiliary stress layer ensures the separation and identification of transient risks and continuous risks, and the buffer layer mapping realizes the adaptive expansion of the safety boundary.

When the temperature gradient of the current working medium exceeds the deformation accumulation value correlation curve, a temporary threshold increase mechanism is triggered.

[0130] Dual-channel verification: The main channel verifies whether the final internal safety index exceeds the dynamic adjustment threshold, and the auxiliary channel detects whether the safety margin component buffer pool in the difference calculation stage reaches the overflow critical value. Triggering either channel initiates the safe state preparation process.
