Description

Technical Field

[0001] The present invention relates to the technical field of battery management, and in particular to a hybrid power supply device. Background Art

[0002] Electricity resources are relatively scarce resources. Because their use is closely related to the laws of human life and production, they show typical peak-valley characteristics. Although the country has introduced different charges for peak and valley electricity consumption, this measure is only a side incentive measure and cannot effectively solve the problem of peak electricity consumption from the root. Through the peak-shaving and valley-filling energy storage system, it can store energy during the valley period of electricity consumption and supply power to electrical equipment during the peak period of electricity consumption, thereby alleviating the power supply pressure and reducing the user's electricity cost. The core components of the peak-shaving and valley-filling energy storage device include battery assemblies. The operating status of the battery assemblies directly affects the operation of the entire peak-shaving and valley-filling energy storage system, so the operating status of the battery assemblies needs to be monitored and managed.

[0028] The beneficial effects of the present invention are as follows:

[0029] 1. Through the setting of the heat dissipation frame, the heat dissipation frame can directly transfer heat from the inside of the photovoltaic module to the outside of the photovoltaic module, which can prevent the high temperature generated in the photovoltaic module from being transferred inside the photovoltaic module, thereby effectively avoiding the reduction of the working efficiency of the photovoltaic module due to high temperature and reducing the service life of the photovoltaic module.

[0030] 2. Through the structure of the heat dissipation frame, the heat-absorbing medium can be introduced into the heat dissipation frame, so that the temperature can be directly cooled from the inside of the photovoltaic module. The cooling effect is obvious. Under the isolation of the heat dissipation frame, the heat-absorbing medium introduced from the outside will not pollute the photovoltaic module and cause damage to the photovoltaic module, and can protect the inside of the photovoltaic module.

[0031] 3. Through the setting of the first piston chamber; when the first piston chamber inhales air inward, the low-temperature air outside the photovoltaic module will enter the horizontal heat dissipation pipe and the longitudinal heat dissipation pipe and absorb the heat inside the photovoltaic module; when the first piston chamber exhausts air outward, the high-temperature air in the heat dissipation frame will be discharged from the horizontal heat dissipation pipe and the longitudinal heat dissipation pipe, thereby achieving the effect of cooling the inside of the photovoltaic module.

[0032] 4. Through the setting of the second piston chamber and the third piston chamber; when the first piston chamber draws cold air into the heat dissipation frame through the second heat dissipation pipe and the fifth heat dissipation pipe, the cold air absorbs the heat generated inside the photovoltaic module in the heat dissipation frame, and the second piston chamber and the third piston chamber discharge the hot air absorbed from the heat dissipation frame to the outside; when the first piston chamber discharges the hot air to the outside, the second piston chamber and the third piston chamber absorb the hot air discharged from the first piston chamber; and so on are repeated, so that the heat generated inside the photovoltaic module can be absorbed and discharged with the cooperation of the first piston chamber and the second piston chamber.

[0033] 5. Through the arrangement of the transverse heat dissipation pipe and the longitudinal heat dissipation pipe, when the light is irradiated into the photovoltaic module, it is refracted under the action of the transverse heat dissipation pipe and the longitudinal heat dissipation pipe, so that the light can be reused in the photovoltaic module, thereby improving the working efficiency of the photovoltaic module.

[0034] 6. By setting the fan, during the process of air intake and exhaust in the first piston chamber, the second piston chamber and the third piston chamber, the flow of gas will cause the fan to rotate, thereby better promoting the flow of air in the heat dissipation frame, so that after the cold air enters the heat dissipation frame, it can be evenly distributed in the heat dissipation frame, thereby evenly absorbing the heat in the photovoltaic module, avoiding excessive local temperature in the photovoltaic module, and improving the heat dissipation efficiency.

[0035] 7. Through the setting of the baffle, spring and mounting seat, during the suction and exhaust process of the first piston chamber, the second piston chamber and the third piston chamber, the fan will drive the mounting seat to move along the length direction of the horizontal heat dissipation pipe and the longitudinal heat dissipation pipe under the elastic action of the spring under the impetus of the air flow, thereby further promoting the flow of air in the heat dissipation frame and improving the heat dissipation efficiency inside the photovoltaic module.

[0036] 8. Through the setting of the one-way valve, the low-temperature air from the outside can only enter the heat dissipation frame through the two ends of the second heat dissipation pipe and the fifth heat dissipation pipe, and the high-temperature air inside the heat dissipation frame can only be discharged through the second piston chamber and the third piston chamber, so that the air can circulate along a certain route, thereby achieving the purpose of heat dissipation.

It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0039] Example 1

[0040] Combination Figure 1 As shown, this embodiment constructs a hybrid power supply system for battery components, which includes battery components and photovoltaic components. The battery components can obtain the power required for charging from the power grid and the photovoltaic components through the corresponding power supply circuit. It can be understood that this hybrid power supply circuit is a relatively mature technology, so it will not be described in detail in this embodiment.

[0041] In order to solve the problems existing in the hybrid power supply system, such as monitoring the health status of battery components, monitoring the temperature of battery components, and monitoring the temperature of photovoltaic components, the following solutions are provided in this embodiment.

[0042] Considering that when the operating temperature of the battery component is low, the electrolyte inside it moves slowly, which in turn affects the transfer activity of lithium ions between the positive and negative electrodes, it will lead to problems such as decreased discharge performance; when the operating temperature of the battery component is high, it will cause irreversible damage to the internal isolation membrane, and even cause battery scrapping or fire accidents.

[0043] Therefore, one of the contributions of this embodiment compared to the prior art is that it provides a thermal management system for energy storage batteries, such as Figure 2-14 shown.

The battery storage device 2100 is used to place battery components, and the constant temperature system is used to provide a constant temperature medium.

[0045] Through the construction in this embodiment, when the temperature sensor detects that the internal temperature of the battery assembly placement cavity 2110 is lower than the set threshold, that is, when the temperature of the battery assembly is too low, the processing unit controls the corresponding three-way solenoid valve 2140 to be turned on, so that the higher temperature constant temperature medium circulates between the first flow channel and the constant temperature system. Further explanation, when the constant temperature medium flows into the first flow channel, the first heat transfer component 2121 works, that is, when the constant temperature medium flows from the first water inlet 2221 to the first water outlet 2131, the first heat transfer component 2121 can transfer the constant temperature medium in the first flow channel to the first water outlet 2131. The heat is transferred to the battery assembly placement chamber 2110, that is, the heat of the constant temperature medium in the first flow channel is transferred to the inside of the battery assembly placement chamber 2110 along the temperature increase channel, so the battery assembly is preferably heated; when the temperature sensor detects that the internal temperature of the battery assembly placement chamber 2110 is higher than the set threshold, that is, when the temperature of the battery assembly is too high, the processing unit controls the corresponding three-way solenoid valve 2140 to be turned on, so that the constant temperature medium with a lower temperature circulates between the second flow channel and the constant temperature system. Further explanation, when the constant temperature medium flows into the second flow channel, the second heat transfer component 2122 That is, in the process of the constant temperature medium flowing from the second water inlet 2222 to the second water outlet 2132, the second heat transfer component 2122 can transfer the heat in the battery component placement cavity 2110 to the constant temperature medium in the second flow channel, that is, the heat in the battery component placement cavity 2110 is transferred to the constant temperature medium in the second flow channel along the cooling channel, thereby better realizing the cooling of the battery component; in summary, this embodiment can reasonably utilize the constant temperature system to control the temperature of the battery component, thereby better realizing the battery component to work at a normal temperature and avoid the influence of extreme weather on the life of the battery component; in addition, the battery component works at a normal temperature, and the electrical conversion rate of the battery component can be maintained at a high level, thereby reducing the loss of chemical substances inside the battery component, thereby extending the service life of the battery component.

[0050] In this embodiment, a protrusion is raised in the middle of one side surface of the mounting block 2310 away from the cover plate 2320, and the protrusion is provided with a rotating cavity 2620 connected to the mounting cavity 2610. A rotating block 2450 extending into the rotating cavity 2620 is provided on the circular plate 2430, and the rotating shaft 2470 is coaxially installed on the rotating block 2450. A bearing 2460 is provided between the side wall of the rotating block 2450 and the inner wall of the rotating cavity 2620.

[0051] Through the arrangement of the rotating chamber 2620, the rotating block 2450 and the bearing 2460 in this embodiment, the rotating block 2450 is preferably located in the rotating chamber 2620 and rotates, which is to say, it is more convenient for the impeller to drive the fan 2260 to rotate.

[0052] Combination Figures 11 to 14 As shown, in this embodiment, a sealing mechanism for slidingly sealing the blade 2440 is provided on the inner wall of the mounting block 2310 and the outer wall of the cylindrical block 2410, a sliding cavity 2510 is provided in the inner wall of the mounting block 2310 or the outer wall of the cylindrical block 2410, a slidable slider 2710 is provided in the sliding cavity 2510, and the end face of the slider 2710 facing the opening end of the sliding cavity 2510 is arc-shaped. When the slider 2710 moves to the maximum stroke toward the opening end of the sliding cavity 2510, one side wall edge of the slider 2710 coincides with the corresponding side wall edge of the opening end of the sliding cavity 2510, and the other side wall edge extends out of the sliding cavity 2510, and both sides of the blade 2440 can abut against the side wall where the slider 2710 extends out of the sliding cavity 2710 to form a sealing surface.

[0053] By setting the sealing mechanism in this embodiment, when the slider 2710 moves to the maximum stroke toward the open end of the sliding cavity 2510, the side wall of the blade 2440 abuts against the side wall of the slider 2710 extending out of the sliding cavity 2510, and the side wall abutting against the blade 2440 and the slider 2710 forms a sealing surface, so that before the impeller rotates, the slider 2710 can keep blocking the driving cavity 2630, so that when the constant temperature medium is injected into the water injection cavity 2330, the constant temperature medium flows into the driving cavity 2630 from the first guide port 2331, so that the driving cavity 2630 corresponding to the first guide port 2331 can be filled with the constant temperature medium, thereby driving the impeller to rotate. When the impeller starts to rotate, the side wall of the blade 2440 can move along the arc surface of the slider 2710. When the impeller rotates at a high speed, the slider 2710 remains retracted into the sliding cavity 2510 under the action of the rotation of the impeller, so it does not affect the rotation of the impeller.

[0054] The purpose of the sealing mechanism is to ensure that the constant temperature medium drives the impeller to rotate, and to avoid the existence of a gap between the blade 2440 and the cylindrical block 2410 and the mounting cavity 2610, which causes the constant temperature medium to flow directly along the gap to the second guide port 2311. In addition, since the slider 2710 extends out of the sliding cavity 2510, the slider 2710 can inhibit the reverse rotation of the impeller, that is, to ensure the unidirectional rotation of the impeller in the mounting cavity 2610. Therefore, this can control the rotation direction of the impeller. Therefore, when the battery assembly is heated up, the fan 2260 blows toward the cavity 2211, that is, the battery assembly is quickly heated to the set threshold value. When the battery assembly is cooled down, the fan 2260 blows away from the cavity 2211, that is, the battery assembly is quickly cooled down to the set threshold value.

[0055] In this embodiment, a first spring 2720 is provided between the slider 2710 and the bottom wall of the sliding cavity 2510 to keep the slider 2710 moving toward the opening of the sliding cavity 2510 .

[0056] By setting the first spring 2720 in this embodiment, before the impeller rotates, the slider 2710 is kept at the maximum stroke toward the opening end of the sliding cavity 2510 under the action of the first spring 2720, that is, a seal is formed between the side wall of the slider 2710 and the side wall of the blade 2440.

[0057] In this embodiment, a sliding groove 2520 is correspondingly provided on the side wall of the sliding cavity 2510, a strip groove 2810 is penetrated on the slider 2710, two limit blocks 2910 are provided in the strip groove 2810, which can extend out of the openings at both ends of the strip groove 2810 respectively, and a second spring 2920 is provided between the two limit blocks 2910, and the end of the limit block 2910 extending out of the strip groove 2810 extends into the corresponding sliding groove 2520.

[0058] By setting the sliding groove 2520, the strip groove 2810, the limit block 2910 and the second spring 2920 in this embodiment, the limit block 2910 slides in the sliding groove, that is, the stability of the sliding of the slider 2710 in the sliding cavity 2510 is guaranteed. Among them, the setting of the second spring 2920 allows the operator to squeeze the limit block 2910 into the strip groove 2810, and then install the slider 2710 in the sliding cavity 2510, which is better and more convenient.

[0059] In this embodiment, at least two groups of sealing mechanisms are provided on the inner wall of the mounting block 2310 and the outer wall of the cylindrical block 2410 .

[0060] The purpose of setting the number of sealing mechanisms in this embodiment is that when the impeller rotates any number of times, there are at least two groups of sealing mechanisms so that the side wall of the slider 2710 forms a seal with the side wall of the blade 2440, thereby ensuring that the constant temperature medium drives the impeller to rotate.

[0061] In this embodiment, filter screens 2150 are disposed on both sides of the housing 2220 , and a water inlet communicating with the first water inlet 2221 or the second water inlet 2222 is disposed on the filter screen 2150 .

[0062] By disposing the filter 2150 in this embodiment, the first heat transfer component 2121 and the second heat transfer component 2122 can be better prevented from being damaged by external forces, while providing air outlets for the heating channel and the cooling channel.

[0063] In this embodiment, heat dissipation fins 2250 are evenly arranged in the cavity 2211 . The heat dissipation fins 2250 are arranged at intervals and form a temperature rising channel or a temperature falling channel.

[0064] By providing the heat dissipation fins 2250 in this embodiment, the internal temperature of the battery assembly placement cavity 2110 can be preferably transferred to the heat dissipation fins 2250, which makes it convenient for the first heat transfer component 2121 or the second heat transfer component 2122 to heat up or cool down the inside of the battery assembly placement cavity 2110, thereby achieving constant temperature control of the battery assembly.

[0065] In a specific use of a thermal management system for an energy storage battery of the present embodiment, when the temperature sensor detects that the internal temperature of the battery assembly placement cavity 2110 is lower than a set threshold value, that is, when the temperature of the battery assembly is too low, the processing unit controls the corresponding three-way solenoid valve 2140 to be turned on, so that the constant temperature medium with a higher temperature circulates between the first flow channel and the constant temperature system. To further illustrate, the constant temperature medium with a higher temperature is injected into the water injection cavity 2330 from the first water inlet 2221, and then flows from the first guide port 2331 to the drive cavity 2630. The first guide port 2331 is tilted, so that the drive cavity 2630 is subjected to thrust, that is, the impeller rotates and is located in the installation cavity 2610, and then the impeller drives the rotating shaft 2470 to rotate, so that the fan 2260 rotates, thereby quickly transferring the heat of the constant temperature medium flowing into the first flow channel to the heat dissipation fins 2250, and then the battery assembly is heated to the set threshold value;

[0066] When the temperature sensor detects that the temperature inside the battery assembly placement chamber 2110 is higher than the set threshold, that is, when the temperature of the battery assembly is too high, the processing unit controls the corresponding three-way solenoid valve 2140 to be turned on, so that the constant temperature medium with a lower temperature circulates between the second flow channel and the constant temperature system. Further explanation: the constant temperature medium with a lower temperature is injected into the water injection chamber 2330 from the second water inlet 2222, and then flows from the first guide port 2331 to the drive chamber 2630. The first guide port 2331 is tilted so that the drive chamber 2630 is subjected to thrust, that is, the impeller rotates in the installation chamber 2610, and then the impeller drives the rotating shaft 2470 to rotate, so that the fan 2260 rotates, thereby quickly transferring the heat on the heat dissipation fins 2250 to the constant temperature medium flowing into the second flow channel, and then the battery assembly is cooled to the set threshold;

[0067] To sum up, the present embodiment can reasonably utilize the constant temperature system to control the temperature of the battery assembly, thereby better realizing that the battery assembly is kept working at a normal temperature and avoiding the influence of extreme weather on the life of the battery assembly; in addition, when the battery assembly works at a normal temperature, the electrical conversion rate of the battery assembly can be maintained at a high level, thereby reducing the loss of chemical substances inside the battery assembly, thereby extending the service life of the battery assembly.

[0068] Among them, the constant temperature system in this embodiment can also include, for example, a device for providing a constant temperature medium. The device for providing a constant temperature medium can be an existing temperature control system (such as water heating, etc.) to achieve better acquisition of circulating constant temperature medium, thereby making the energy storage battery thermal management system of this embodiment have strong applicability.

[0069] In addition, although there are devices that can cool down photovoltaic modules from the outside, the temperature of the photovoltaic modules is generated inside them, and the high temperature must be transferred to the heat dissipation and cooling devices through the photovoltaic modules. During this process, the photovoltaic modules will still work in a high-temperature environment, which will still cause the temperature of the photovoltaic modules to be high, thereby affecting the working efficiency of the photovoltaic modules and shortening the service life of the photovoltaic modules.

[0070] Considering that excessively high temperatures inside a photovoltaic module may affect its conversion efficiency and service life, another contribution of this embodiment to the prior art is to provide a hybrid power supply device, in particular, a technical solution for controlling the temperature of a photovoltaic module from the inside.

[0071] like Figure 15-32 As shown, this embodiment provides a hybrid power supply device, which includes a photovoltaic module 1100, and the photovoltaic module 1100 is packaged by photovoltaic glass 1110, a first photovoltaic adhesive film 1120, a battery cell 1130, a second photovoltaic adhesive film 1140 and a photovoltaic backplane 1150;

[0072] The photovoltaic module 1100 further includes a heat dissipation frame 1160 disposed between the second photovoltaic adhesive film 1140 and the photovoltaic back sheet 1150;

[0073] The heat dissipation frame 1160 includes a plurality of transverse heat dissipation pipes arranged in parallel with each other and connected to the outside of the photovoltaic module 1100 and a plurality of longitudinal heat dissipation pipes arranged in parallel with each other and connected to the outside of the photovoltaic module 1100. The transverse heat dissipation pipes are connected to the longitudinal heat dissipation pipes.

[0074] In this embodiment, the hybrid power supply device includes an energy storage device and a photovoltaic assembly 1100 electrically connected to the energy storage device; the energy storage device is electrically connected to the power grid and the power consumption device respectively; the power grid and the photovoltaic assembly 1100 are used to provide power to the energy storage device, and the energy storage device is used to provide power to the power consumption device;

[0075] By setting the heat dissipation frame 1160 in this embodiment, the heat dissipation frame 1160 can directly transfer heat from the inside of the photovoltaic module 1100 to the outside of the photovoltaic module 1100, which can prevent the high temperature generated in the photovoltaic module 1100 from being transferred inside the photovoltaic module 1100, thereby effectively preventing the working efficiency of the photovoltaic module 1100 from being reduced due to high temperature and reducing the service life of the photovoltaic module 1100;

[0076] Through the structure of the heat dissipation skeleton 1160, the heat-absorbing medium can be introduced into the heat dissipation skeleton 1160, so that the temperature of the photovoltaic module 1100 can be directly cooled from the inside, and the cooling effect is obvious. In addition, under the isolation of the heat dissipation skeleton 1160, the heat-absorbing medium introduced from the outside will not pollute the photovoltaic module 1100 and cause damage to the photovoltaic module 1100, and can protect the inside of the photovoltaic module 1100.

[0077] In this embodiment, the transverse heat pipe includes a first heat pipe 1210, a second heat pipe 1220 and a third heat pipe 1230 which are arranged in sequence, and the longitudinal heat pipe includes a fourth heat pipe 1240, a fifth heat pipe 1250 and a sixth heat pipe 1260 which are arranged in sequence.

[0078] In this embodiment, the photovoltaic assembly 1100 can also directly provide electrical energy to the first electric telescopic rod 1271;

[0079] Through the arrangement of the first piston chamber 1270 in this embodiment; when the photovoltaic assembly 1100 starts to work and generates electricity, the photovoltaic assembly 1100 will provide electricity to the first electric telescopic rod 1271, so that the first electric telescopic rod 1271 starts to work; the driving shaft of the first electric telescopic rod 1271 is sealed and connected to the first piston chamber 1270, so that when the first electric telescopic rod 1271 When the output shaft moves toward the first piston chamber 1270, the airflow in the first piston chamber 1270 is squeezed out of the first piston chamber 1270 under the extrusion of the output shaft of the first electric telescopic rod 1271. When the output shaft of the first electric telescopic rod 1271 moves toward the outside of the first piston chamber 1270, the airflow is sucked inward by the first piston chamber 1270. The absorption and discharge of the airflow by the first piston chamber 1270 promotes the airflow in the heat dissipation skeleton 1160 to flow better. When the first piston chamber 1270 inhales air inward, the low-temperature air outside the photovoltaic module 1100 will enter the horizontal heat dissipation pipe and the longitudinal heat dissipation pipe and absorb the heat inside the photovoltaic module 1100. When the first piston chamber 1270 exhausts air outward, the high-temperature air in the heat dissipation skeleton 1160 will be discharged from the horizontal heat dissipation pipe and the longitudinal heat dissipation pipe, thereby achieving the effect of cooling the inside of the photovoltaic module 1100.

[0119] Step S3: output the health status of the battery.

[0120] Through the above steps S1-S3, the health status of the battery based on the health status assessment model can be better evaluated, so the advantages of the algorithm can be better utilized to achieve a better evaluation of the health status of the battery.

[0121] Step S1 in this embodiment specifically includes the following steps:

[0122] Step S11, obtain the battery's working state M, working voltage U, working current I, working time T, and internal temperature K o And the ambient temperature K;

[0123] In this step, when the working state of the battery is the discharge state, M=1, and when the working state of the battery is the charge state, M=0;

[0124] Step S12: Calculate the working voltage U, working current I, working time T, and internal temperature K. o And the ambient temperature K is dimensionless, and then the dimensionless working voltage U is obtained * , working current I * , working hours T * 、Internal temperature K o* And the ambient temperature K * ;

[0125] Step S13: construct a diagnostic input sequence S, S = [M, U * ,I * ,T * ,K o* ,K * ].

[0126] Through step S11, the working state, working voltage, working current, working time, internal temperature and ambient temperature of the battery can be comprehensively considered, so that the correlation sequence between the internal temperature and the battery operating state and the external environment can be better constructed. Through steps S12 and S13, the dimension removal can be better achieved, so that the processing of the health status assessment model can be better facilitated.

[0127] In this embodiment, the working state M, the working voltage U, the working current I, the working time T and the internal temperature K o It can be obtained through the existing BMS system. The working voltage U and working current I refer to the instantaneous data at the time of collection. The working time T refers to the time from the time when the battery component starts working to the time of collection. The internal temperature K o Refers to the cell temperature of the battery assembly. The cell temperature can be used as a parameter for evaluating the heat generation of the battery assembly.

[0128] Since the battery assembly in this embodiment is disposed in the battery assembly placement cavity 2110, the measurement data of the temperature sensor can be directly used as the ambient temperature K * .

[0135] Among them, U max ,I max 、T max , K o max and K max They are maximum operating voltage, maximum operating current, maximum operating time, maximum internal temperature and maximum ambient temperature.

[0136] Through the above, it is possible to better obtain dimensionless parameters. max ,Imax and T max The working time can be calculated by using the rated voltage (distinguishing between discharge state and charge state) and rated current (distinguishing between discharge state and charge state) of the battery module, as well as the rated power (distinguishing between discharge state and charge state) and nominal capacity of the battery module, K o max and K max The temperatures can be manually set based on experience, for example, to 60° C. and 40° C., respectively.

[0137] The health status assessment model in step S2 of this embodiment is constructed by the following steps:

[0138] Step S21, constructing a health status assessment model;

[0139] Step S22: construct a sample set P and train the health status assessment model.

[0142] The fully connected layer can have N layers connected in sequence, and the output of the previous fully connected layer is used as input by the subsequent fully connected layer; for the i-th fully connected layer in the N layers, its output sequence y i With the input sequence x i There is the following relationship between them:

[0143] y i =ω i x i +b i ;

[0144] Among them, ω i is the weight term of the i-th fully connected layer, b i is the bias term of the i-th fully connected layer, and the weight term ω i and the bias term b i Acquired through step S22.

[0145] Through the above, the construction of a health status assessment model can be better realized with the help of existing mature neural network algorithms.

[0146] In step S22 of this embodiment, the sample set P has multiple sample sequences, and the multiple sample sequences are collected from batteries in different working states and different cycle times; each sample sequence is labeled with the capacity decay value Q of the battery.

[0147] For the jth sample, its label Q i The calculation formula is, Q ia is the actual full charge of the battery corresponding to the jth sample in the current state, Q ic is the nominal full charge of the battery corresponding to the jth sample;

[0148] For the jth sample, its sample sequence is, M j , and They respectively represent the working state, dimensionless working voltage, dimensionless working current, dimensionless working time, dimensionless internal temperature and dimensionless ambient temperature of the j-th sample.

[0149] Through the above, the sample database can be better obtained, especially because the capacity decay value Q is used as the label, so the final output result of the health status assessment model can be a specific value, rather than the classified data output by the classifier, which can better facilitate subsequent threshold judgment and early warning processing.
