[0025] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0026] Figure 1 is a flowchart of a vehicle battery abnormality processing method provided by an example embodiment of the present disclosure. The method can be applied to an automatic train scheduling system (ATS). As shown in Figure 1 , the method can include S101 and S102.
[0027] S101, obtaining abnormality information of a battery, wherein the abnormality information includes alarm information indicating that the battery currently has an abnormality, and / or early warning information indicating that the battery will have an abnormality in the future.
[0028] For example, the battery can be a power battery of any car of a train. The abnormality information of the battery can be uploaded by an intelligent operation and maintenance platform, or uploaded by other devices capable of determining the abnormality information of the battery, which is not limited here.
[0029] The alarm information indicating that the battery currently has an abnormality can include capacity alarm information indicating that the real-time capacity of the battery is abnormal, and / or decay rate alarm information indicating that the real-time capacity decay rate of the battery is abnormal; the early warning information indicating that the battery will have an abnormality in the future can include capacity early warning information indicating that the predicted capacity of the battery is abnormal, and / or decay rate early warning information indicating that the predicted capacity decay rate of the battery is abnormal. For example, the capacity alarm information can represent that the real-time capacity of the battery is less than a capacity threshold; the capacity early warning information can represent that the predicted capacity of the battery is less than the capacity threshold; the decay rate alarm information can represent that the real-time decay rate is greater than a decay rate threshold; and the decay rate early warning information can represent that the predicted decay rate is greater than the decay rate threshold. The capacity threshold and the decay rate threshold can be pre-set based on actual needs. If the abnormality information of the battery is obtained, it can be determined that the battery currently or in the future has an abnormality. In order to ensure the operation safety of the vehicle, the corresponding abnormality processing strategy can be taken in combination with the marshalling number of the vehicle.
[0030] S102, determining an abnormality processing strategy according to the marshalling number of the vehicle and the abnormality information.
[0031] For example, if the vehicle is a single-formation vehicle, the running state of a single car does not affect other cars in the same formation; if the vehicle is a multi-formation vehicle, the running state of a single car can affect other cars in the same formation, and the cars in the same formation can provide electric energy to each other, for example, if the power battery of the second car is abnormal, the power batteries of the first car and the third car can temporarily provide running energy. Therefore, according to the number of formations of the vehicle, different abnormal handling strategies that can adapt to the actual running state of the vehicle can be provided for single-formation vehicles and multi-formation vehicles.
[0032] For example, when the vehicle is a single-formation vehicle and the abnormal information is alarm information indicating that the battery currently has an abnormality, the vehicle can be controlled to stop running to ensure the safety of the vehicle. For another example, when the vehicle is a single-formation vehicle and the abnormal information is early warning information indicating that the battery will have an abnormality in the future, the vehicle operation strategy can be adjusted to reduce the planned mileage of the vehicle to reduce the possibility of the vehicle having an abnormality in subsequent operation, so that the vehicle can complete the operation plan before the abnormality occurs. For another example, when the vehicle is a multi-formation vehicle and the abnormal information is alarm information indicating that the battery currently has an abnormality, if the distance to the next station is less than a distance threshold, the vehicle can be stopped from going online when it arrives at the next station to minimize the impact on passengers in the vehicle; if the distance to the next station is not less than the distance threshold, the vehicle can be directly stopped from going online. For another example, when the vehicle is a multi-formation vehicle and the abnormal information is early warning information indicating that the battery will have an abnormality in the future, the vehicle can be marked and the vehicle operation strategy can be adjusted to reduce the planned mileage of the vehicle to reduce the possibility of the vehicle having an abnormality in subsequent operation, so that the vehicle can complete the operation plan before the abnormality occurs.
[0033] In the above technical solution, the abnormal information of the battery is obtained, wherein the abnormal information includes alarm information indicating that the battery currently has an abnormality and / or early warning information indicating that the battery will have an abnormality in the future; and the abnormal handling strategy is determined according to the number of formations of the vehicle and the abnormal information. In this way, when it is determined that the battery of the vehicle currently has an abnormality or will have an abnormality in the future, a handling strategy that can adapt to the actual state of the vehicle can be quickly determined in combination with the number of formations of the vehicle, so that the battery on the train can be more accurately and timely maintained, and the operation safety of the vehicle is improved.
[0034] In an optional embodiment, the vehicle battery abnormal handling method provided by the present disclosure can further include:
[0035] When the information indicating the abnormality of the capacity attenuation rate is received, the received information is displayed.
[0036] For example, receiving the information indicating the abnormality of the capacity attenuation rate is receiving the attenuation rate alarm information and / or the attenuation rate early warning information. When the information indicating the abnormality of the capacity attenuation rate is received, it can be determined that the battery has an abnormal attenuation rate or is extremely likely to have an abnormal attenuation rate at a future time. The abnormality of the attenuation rate is relatively complex to troubleshoot. To ensure the accuracy of troubleshooting and maintenance, the received information indicating the abnormality of the capacity attenuation rate can be displayed on the display screen of the vehicle dispatching system ATS, so as to timely remind the relevant personnel to troubleshoot the factors that may cause the battery capacity attenuation rate to be too fast, and propose a solution, thereby ensuring the subsequent operation safety of the vehicle.
[0037] In an optional embodiment, in S102, the abnormality processing strategy is determined according to the number of vehicle groupings and the abnormality information, which can include:
[0038] When the information indicating the abnormality of the capacity size is received and the information indicating the abnormality of the capacity attenuation rate is not received, the abnormality processing strategy is determined according to the number of groupings and the information indicating the abnormality of the capacity size.
[0039] For example, receiving the information indicating the abnormality of the capacity size is receiving the capacity alarm information and / or the capacity early warning information; and not receiving the information indicating the abnormality of the capacity attenuation rate is not receiving the attenuation rate alarm information or the attenuation rate early warning information.
[0040] If the information indicating the abnormality of the capacity size is received and the information indicating the abnormality of the capacity attenuation rate is not received, it can be determined that the battery has no abnormal attenuation rate, and the abnormality of the battery is related to the size of the battery capacity. At this time, the abnormality processing strategy can be determined according to the number of groupings and the information indicating the abnormality of the capacity size.
[0041] In an optional embodiment, when the information indicating the abnormality of the capacity size is received and the information indicating the abnormality of the capacity attenuation rate is not received, the abnormality processing strategy is determined according to the number of groupings and the information indicating the abnormality of the capacity size, which can include:
[0042] When the information indicating the abnormality of the capacity size is received and the information indicating the abnormality of the capacity attenuation rate is not received, if the vehicle is a single grouping vehicle and the received information is the capacity alarm information, the vehicle is controlled to stop operation, and a dispatching and maintenance request is generated.
[0043] For example, the vehicle is a single-unit vehicle, and there is no other vehicle compartment that can affect the running state of the vehicle compartment where the abnormal battery is located; the received information is the capacity warning information, and it can be determined that the battery has an abnormality related to the capacity size, and the abnormality may directly affect the current operation safety of the vehicle. Therefore, in order to ensure the operation safety of the vehicle, the vehicle can be controlled to stop operation, and a dispatch repair request can be generated. In this way, while the vehicle is stopped from online operation, relevant personnel can timely dispatch other vehicles to replace the abnormal vehicle for operation based on the dispatch repair request, and timely arrange to repair the battery of the vehicle to solve the abnormality of the battery as soon as possible. Further, the battery processing suggestion such as replacing the battery pack can also be generated at the same time as the dispatch repair request is generated.
[0044] In an optional embodiment, when the information indicating the capacity size abnormality is received and the information indicating the capacity decay rate abnormality is not received, the abnormality processing strategy is determined according to the number of units and the information indicating the capacity size abnormality, which can include:
[0045] When the information indicating the capacity size abnormality is received and the information indicating the capacity decay rate abnormality is not received, if the vehicle is a single-unit vehicle and the received information is the capacity warning information, the abnormality processing strategy is determined according to the predicted capacity decay rate and the first capacity decay rate threshold.
[0046] For example, the vehicle is a single-unit vehicle, and there is no other vehicle compartment that can affect the running state of the vehicle compartment where the abnormal battery is located; the received information is the capacity warning information, and it can be determined that the battery has an abnormality related to the capacity size, and the abnormality may directly affect the current operation safety of the vehicle. Therefore, in order to ensure the operation safety of the vehicle, the vehicle can be controlled to stop operation, and a dispatch repair request can be generated. In this way, while the vehicle is stopped from online operation, relevant personnel can timely dispatch other vehicles to replace the abnormal vehicle for operation based on the dispatch repair request, and timely arrange to repair the battery of the vehicle to solve the abnormality of the battery as soon as possible. Further, the battery processing suggestion such as replacing the battery pack can also be generated at the same time as the dispatch repair request is generated.
[0047] Optionally, the abnormality processing strategy is determined according to the predicted capacity decay rate and the first capacity decay rate threshold, which can include:
[0048] If the predicted capacity decay rate is greater than the first capacity decay rate threshold, a battery capacity recalibration request is generated; or,
[0049] If the predicted capacity decay rate is less than or equal to the first capacity decay rate threshold, a vehicle operation strategy adjustment request is generated.
[0050] For example, the first capacity decay rate threshold can be set to 10%. The predicted capacity decay rate can be determined based on the predicted capacity. If the predicted capacity decay rate is greater than the first capacity decay rate threshold, it can be determined that the accuracy of the predicted capacity may be insufficient, and the received information is capacity warning information, that is, the battery has not yet had any abnormalities related to the capacity size at the current moment. Therefore, a request to recalibrate the battery capacity can be generated to re-determine the real-time capacity and predicted capacity of the battery, thereby ensuring the reliability of the subsequent abnormality handling strategy. Among them, the request to recalibrate the battery capacity can be sent by the vehicle dispatch system ATS to the intelligent operation and maintenance platform, so that the intelligent operation and maintenance platform can recalibrate the battery capacity.
[0051] If the predicted capacity decay rate is less than or equal to the first capacity decay rate threshold, it can be determined that the predicted capacity is highly accurate and the received information is capacity warning information, meaning that the battery has not yet experienced any abnormality related to capacity size at the current moment. A vehicle operation strategy adjustment request can be generated at this time to reduce the possibility of abnormalities occurring in the subsequent operation of the vehicle and enable the vehicle to complete its operation plan before the abnormality occurs. For example, the possibility of abnormalities occurring in the subsequent operation of the vehicle can be reduced by reducing the mileage of the vehicle's planned operation. In addition, the vehicle operation strategy adjustment request may include information indicating the predicted capacity decay rate and the first capacity decay rate threshold to facilitate relevant personnel in adjusting the vehicle's operation strategy.
[0052] In an optional embodiment, when information indicating a capacity size abnormality is received and information indicating a capacity decay rate abnormality is not received, determining an abnormality handling strategy based on the number of trains and the information indicating a capacity size abnormality may include:
[0053] When receiving information indicating abnormal capacity size and not receiving information indicating abnormal capacity decay rate, if the vehicle is a multi-unit vehicle and the received information is a capacity alarm information, determining the real-time average capacity decay rate of the batteries of the vehicles in the unit;
[0054] Determine the abnormality handling strategy based on the real-time average capacity decay rate and the second capacity decay rate threshold.
[0055] For example, if the train is a multi-unit train, there may be other train cars that can affect the operating status of the train car where the abnormal battery is located. If the received information is a capacity alarm, it can be determined that the battery is very likely to have an abnormality related to the capacity size, and this abnormality may directly affect the current operation of the train. In this case, the real-time average capacity decay rate of the batteries in the train car can be determined to determine the extent of the abnormality's impact on the train operation, and then determine the abnormality handling strategy to be adopted. The average capacity decay rate r can be determined using the following formula:
[0056]
[0057] wherein A0is the initial capacity of the battery of each car, A k is the capacity of the battery of the kth car, m is the total number of cars, and k ranges from 1 to m. In determining the real-time average capacity decay rate, the specific value of A k may be the real-time capacity of the battery of the kth car; in determining the predicted average capacity decay rate, the specific value of A k may be the predicted capacity of the battery of the kth car. The second capacity decay rate threshold value can be pre-set, for example, can be set to 15%, and the first capacity decay rate threshold value can be less than the second capacity decay rate threshold value.
[0058] Optionally, determining the abnormality handling strategy according to the real-time average capacity decay rate and the second capacity decay rate threshold value can comprise:
[0059] if the real-time average capacity decay rate is greater than the second capacity decay rate threshold value, controlling the vehicle to stop operation and generating a dispatch repair request; or,
[0060] if the real-time average capacity decay rate is less than or equal to the second capacity decay rate threshold value, marking the vehicle, controlling the vehicle to continue operation and generating a vehicle operation strategy adjustment request.
[0061] For example, if the real-time average capacity decay rate is greater than the second capacity decay rate threshold value, it can be determined that the actual capacity decay rate of the vehicle as a whole is large, and even if it continues to run, there is a large risk of operation. Therefore, the vehicle can be controlled to stop operation, and a dispatch repair request can be generated to repair the vehicle and call other vehicles to replace its operation.
[0062] If the real-time average capacity decay rate is less than or equal to the second capacity decay rate threshold value, it can be determined that the actual capacity decay rate of the vehicle as a whole is small, and safe operation within a certain mileage can still be maintained, so the vehicle can be controlled to continue operation. However, although the operation at this time can continue to be maintained, there is a certain risk, so a vehicle operation strategy adjustment request is generated to reduce the possibility of abnormality of the vehicle in subsequent operation. In addition, since there is a certain risk in its operation, the vehicle can be marked so that relevant personnel pay special attention to it, and the vehicle can be quickly located for repair after it is parked. The vehicle operation strategy adjustment request can include information indicating the real-time average capacity decay rate and the second capacity decay rate threshold value, so that relevant personnel can adjust the operation strategy of the vehicle.
[0063] In an optional embodiment, when the information indicating the capacity size abnormality is received and the information indicating the capacity decay rate abnormality is not received, determining the abnormality handling strategy according to the marshalling number and the information indicating the capacity size abnormality can comprise:
[0064] determining a predicted average capacity fade rate of the vehicle batteries within the consist, when the received information is capacity warning information and the vehicle is a multiple unit vehicle;
[0065] determining an abnormality handling strategy according to the predicted average capacity fade rate and a first capacity fade rate threshold.
[0066] For example, the vehicle is a multiple unit vehicle, and there are other carriages that can affect the running state of the carriage where the abnormal battery is located. The received information is capacity warning information, which can determine that the battery is likely to have a capacity size-related abnormality in the future, and the abnormality may affect the future operation of the vehicle. At this time, the predicted average capacity fade rate of the vehicle batteries within the consist can be determined to determine the degree of influence of the vehicle by the battery abnormality at a future time, and then determine the abnormality handling strategy to be adopted.
[0067] Optionally, determining an abnormality handling strategy according to the predicted average capacity fade rate and a first capacity fade rate threshold can include:
[0068] If the predicted average capacity fade rate is greater than the first capacity fade rate threshold, a battery capacity recalibration request is generated and a vehicle operation strategy adjustment request is generated; or,
[0069] If the predicted average capacity fade rate is less than or equal to the first capacity fade rate threshold, the vehicle is controlled to maintain the current operation strategy to continue operation.
[0070] For example, if the predicted average capacity fade rate is greater than the first capacity fade rate threshold, it may be affected by the lack of accuracy of the predicted capacity, and the received information is capacity warning information, i.e. the battery has not yet appeared a capacity size-related abnormality at the current time, therefore, a battery capacity recalibration request can be generated. And the predicted average capacity fade rate is greater than the first capacity fade rate threshold, which can determine that the degree of influence of the vehicle by the battery abnormality at a future time may be large, in order to ensure the safety of the subsequent operation of the vehicle, a vehicle operation strategy adjustment request can be generated to reduce the possibility of the vehicle appearing abnormal in the subsequent operation process, so that the vehicle completes the operation plan before the abnormality occurs.
[0071] If the predicted average capacity fade rate is less than or equal to the first capacity fade rate threshold, it can be determined that the degree of influence of the vehicle by the battery abnormality at a future time may be small, and the safety of the subsequent operation of the vehicle is high, and the vehicle can be controlled to maintain the current operation strategy to continue operation, in order to reduce the change to the vehicle operation plan.
[0072] Figure 2 is a flowchart of a vehicle battery abnormality handling method provided by an exemplary embodiment of the present disclosure. The method can be applied to an ATS vehicle scheduling system, and the method is used to Figure 2The implementation process of the vehicle battery abnormality processing method provided by the present disclosure can be more clearly understood. As shown in Figure 2 The method can include S201 to S218.
[0073] S201, it is judged whether the attenuation rate alarm information or the attenuation rate early warning information is received. If yes, S202 is executed, and if no, S203 is executed.
[0074] S202, the received information is displayed.

[0077] S205, it is judged whether the predicted capacity attenuation rate is greater than the first capacity attenuation rate threshold. If yes, S206 is executed, and if no, S207 is executed.
[0078] S206, a battery capacity recalibration request is generated.
[0079] S207, a vehicle operation strategy adjustment request is generated.
[0080] S208, the predicted average capacity attenuation rate of the vehicle battery in the formation is determined.
[0081] S209, it is judged whether the predicted average capacity attenuation rate is greater than the first capacity attenuation rate threshold. If yes, 210 is executed, and if no, S211 is executed.
[0082] S210, a battery capacity recalibration request is generated and a vehicle operation strategy adjustment request is generated.
[0083] S211, the vehicle is controlled to maintain the current operation strategy to continue running.
[0084] S212, it is judged whether the capacity alarm information is received. If yes, S213 is executed, and if no, S201 is re-executed.
[0085] S213, it is judged whether the vehicle is a single-formation vehicle. If yes, S214 is executed, and if no, S215 is executed.
[0086] S214, the vehicle is controlled to stop operation, and a dispatch repair request is generated.
[0087] S215, the real-time average capacity attenuation rate of the vehicle battery in the formation is determined.
[0088] S216, determining whether the real-time average capacity attenuation rate is greater than a second capacity attenuation rate threshold. If yes, S217 is executed, and if no, S218 is executed.
[0089] S217, controlling the vehicle to stop operation and generating a dispatch repair request.
[0090] S218, marking the vehicle, controlling the vehicle to continue operation and generating a vehicle operation strategy adjustment request.
[0091] In this way, it can be determined whether the battery of the vehicle may have a capacity size abnormality or a capacity attenuation rate abnormality from the current and future dimensions, and in combination with the number of vehicle marshalling, a processing strategy suitable for the actual state of the vehicle can be quickly determined, the dependence on manpower is reduced, and the batteries on the train can be maintained and maintained in time more accurately, and the operation safety of the vehicle is improved.
[0092] Figure 3 is a flowchart of a vehicle battery abnormal information determination method provided by an example embodiment of the present disclosure. The method can be applied to an intelligent operation and maintenance platform, specifically, to a battery attenuation monitoring platform of the intelligent operation and maintenance platform. As shown in Figure 3 , the method can include S301 and S302.
[0093] S301, determining the predicted capacity of the battery through a pre-trained battery capacity prediction model, wherein the battery capacity prediction model is obtained based on a golden section search algorithm optimization.
[0094] For example, the battery can refer to the power battery of any car of the train. The model can be pre-stored in the intelligent operation and maintenance platform. As shown in Figure 4 , the real-time data of the battery can be collected by a high-voltage detection module (HVSU) inside the battery, and the real-time data can be forwarded to the information terminal of the vehicle through the battery management controller (BMS) for storage. The information terminal can transmit the real-time data to the intelligent operation and maintenance platform through wireless communication technology, such as a 4G network, and then input the real-time data as reference data into the battery capacity prediction model to obtain the predicted capacity output by the battery capacity prediction model. The predicted capacity can refer to the estimated value of the battery capacity after half a year, or the estimated value of the battery capacity after other target time, and the specific target time can be set based on actual needs. The real-time data can include the current time, the current environment temperature, and the number of battery cycles, etc. The number of battery cycles can refer to the number of complete charge and discharge cycles of the battery.
[0095] Currently, power batteries are applied to urban rail trains. Once the power battery fails, it may cause the running line to be out of service, and therefore, higher requirements are put forward for the early prediction of train power battery failures. In the vehicle battery abnormal information determination method provided in the present disclosure, the predicted capacity of the battery is determined by the battery capacity prediction model optimized based on the tentacle search algorithm, and the tentacle search algorithm has the characteristics of simple principle, few parameters and less calculation, and has an advantage in processing low-dimensional optimization targets. Therefore, the battery capacity prediction model optimized based on the tentacle search algorithm can quickly determine the predicted capacity with high accuracy.
[0096] S302, generating abnormal information of the battery according to the real-time capacity and the predicted capacity, wherein the abnormal information is used to implement the vehicle battery abnormality processing method described in any of the above embodiments.
[0097] For example, the real-time capacity of the rail vehicle battery, i.e., the battery described above, can be automatically collected by the ampere-hour integration method, i.e., the actual charging current and time of the battery during the charging and discharging process, to calculate the real-time capacity of the battery. The real-time capacity and the predicted capacity are for the same battery. The abnormal information of the battery can refer to at least one of the capacity alarm information, the capacity early warning information, the decay rate alarm information and the decay rate early warning information described above. After generating the abnormal information of the battery, the intelligent operation and maintenance platform can upload the abnormal information to the vehicle dispatching system ATS, so that the vehicle dispatching system ATS determines the abnormality processing method to be adopted.
[0098] The battery capacity prediction model optimized based on the tentacle search algorithm can quickly determine the predicted capacity with high accuracy; according to the real-time capacity and the predicted capacity, when it is determined that the battery of the vehicle is abnormal at present or in the future, the corresponding abnormal information can be generated, and the comprehensiveness of the abnormal information is improved. Therefore, reliable judgment basis can be provided for the determination of subsequent abnormality processing strategies.
[0099] In an optional embodiment, the predicted capacity of the battery is determined by the battery capacity prediction model trained in advance, comprising:
[0100] The reference data of the battery and the target time are input into the battery capacity prediction model to obtain the predicted capacity corresponding to the target time, wherein the reference data includes the reference time, the reference environmental temperature and the reference number of cycles of the battery.
[0101] For example, the reference data can be the real-time data of the battery collected by the HVSU. The target time can be set by the user and input into the battery capacity prediction model. That is, the content input into the battery capacity prediction model is the reference data of the battery and the target time, and the output content of the battery capacity prediction model is the predicted capacity of the battery.
[0102] Alternatively, the battery capacity prediction model can be trained in the following way:
[0103] obtain training data;
[0104] input the training data into a preset model, and optimize initialization parameters of the preset model based on a tentacle search algorithm until a condition of completing training is met, to obtain a battery capacity prediction model.
[0105] The training data can include, in a charging process starting from an initial SOC value of the battery being less than or equal to a first SOC threshold and ending when the SOC of the battery reaches a second SOC threshold, historical cycle times, historical capacities, historical times and historical ambient temperatures of the battery. The first SOC threshold can be set to 5%, and the second SOC threshold can be set to 100%. The composition of each training data can be s j = [T j , R j , C j ], where s j is the jth training data, T j is the historical time in the jth training data, R j is the historical ambient temperature in the jth training data, and C j is the historical cycle times in the jth training data. The condition of completing training can be that the number of iterations of the model reaches a preset number of iterations.
[0106] In the process of fully charging the battery, the intelligent operation and maintenance platform can first determine whether the SOC of the battery is less than or equal to 5%; if so, data is continuously recorded starting from the moment of starting charging, and the recorded data can include the SOC, the current, the current ambient temperature, the cumulative charging capacity and other information of the battery during the charging period; if not, no data is recorded. When the battery is charged to 100%, the data recording can be stopped, and the data recorded during this period can be used as training data in the future. If the charging is stopped when the SOC of the battery does not reach 100%, the data is not exported, i.e., it is not used as training data in the future; if the charging is not stopped when the SOC of the battery reaches 100%, the data is exported when the SOC of the battery just reaches 100%, and the subsequent data is not recorded and is not used as training data in the future.

The ith input data s i may include the corresponding time T i , the ambient temperature R i of the battery, and the cycle number C i . Wherein, the first weight matrix w1, the second weight matrix w2 and the bias matrix w3 are the parameters to be optimized in the preset model.
[0110] Optionally, the fitness function f(x) of the preset model can be constructed according to the following formula:
[0111]
[0112] Wherein, y j0 is the actual historical capacity of the jth training data, y j is the predicted historical capacity of the jth training data, and n is the total amount of training data.
[0113] Wherein, the process of optimizing the initialization parameters of the preset model by the weaver search algorithm can include:
[0114] determining the normalized weaver orientation;
[0115] determining the left weaver position and the right weaver position of the weaver according to the weaver orientation, the weaver centroid position and the distance between the two weaver antennae of the weaver;
[0116] calculating the fitness of the left weaver position and the fitness of the right weaver position of the weaver through the fitness function f(x) above;
[0117] updating the weaver centroid position and the parameters to be optimized according to the fitness of the two weaver positions and the step length, wherein the step length and the iteration number are in a negative correlation, that is, the step length decreases with the increase of the iteration number;
[0118] iteratively executing the above steps until the iteration number reaches the preset iteration number, to obtain the optimized initialization parameters.
[0119] Wherein, the normalized weaver orientation can be determined by the following formula
[0120]
[0121] Wherein, random(3,3) is a randomly generated matrix with a shape of 3x3, and ‖·‖ is a normalization processing function.
[0122] The left weaver position of the weaver can be determined by the following formula The right weaver position of the weaver can be determined by the following formula Wherein, x t is the weaver centroid position at time t, and dt is the distance between the two antennae of the beetle at time t.
[0123] The position of the centroid of the beetle can be updated by the following equation:
[0124]
[0125] where x t is the position of the centroid of the beetle at time t, x t+1 is the position of the centroid of the beetle at time t+1, δ t is the step size, is the normalized orientation of the antennae of the beetle, sign(·) is the sign function, is the fitness of the left antenna position, is the fitness of the right antenna position.
[0126] As described above, the beetle antenna algorithm has the characteristics of simple principle, few parameters and small amount of calculation, and has an advantage in processing low-dimensional optimization targets. Therefore, based on the beetle antenna search algorithm to optimize the initialization parameters of the preset model, a battery capacity prediction model with high accuracy can be simply and quickly determined to determine the accurate predicted capacity through the battery capacity prediction model.
[0127] In an optional embodiment, in S302, the abnormal information of the battery is generated according to the real-time capacity and the predicted capacity, which can include:
[0128] generating information indicating a capacity size abnormality according to the real-time capacity and the predicted capacity;
[0129] determining a predicted attenuation rate according to the predicted capacity;
[0130] generating information indicating a capacity attenuation rate abnormality according to the real-time attenuation rate and the predicted attenuation rate.
[0131] For example, the information indicating a capacity size abnormality is generated according to the real-time capacity and the predicted capacity, which can include:
[0132] If the real-time capacity is less than a capacity threshold, capacity alarm information indicating a real-time capacity size abnormality of the battery is generated; if the predicted capacity is less than the capacity threshold, capacity warning information indicating a predicted capacity size abnormality of the battery is generated.
[0133] The capacity threshold can be pre-set based on actual needs, for example, can be set to 80%. If the real-time capacity is less than the capacity threshold, it can be determined that the current battery capacity size is abnormal, and the capacity alarm information is generated. If the predicted capacity is less than the capacity threshold, it can be determined that the battery capacity at a target time, i.e., at a certain time in the future, can be an abnormal value, and the capacity warning information is generated.
[0134] For example, a predicted attenuation curve of the battery capacity can be generated based on the predicted capacities at multiple time points, and a slope of the curve corresponding to the target time is determined as the corresponding predicted attenuation rate. The real-time attenuation rate and the predicted attenuation rate are for the same battery.
[0135] For example, generating information indicating an abnormality of the capacity attenuation rate according to the real-time attenuation rate and the predicted attenuation rate can include:
[0136] If the real-time attenuation rate is greater than the attenuation rate threshold, attenuation rate alarm information indicating an abnormality of the real-time capacity attenuation rate of the battery is generated; if the predicted attenuation rate is greater than the attenuation rate threshold, attenuation rate early warning information indicating an abnormality of the predicted capacity attenuation rate of the battery is generated.
[0137] The attenuation rate threshold can be pre-set based on actual needs. If the real-time attenuation rate is greater than the attenuation rate threshold, it can be determined that the current battery capacity attenuation rate has an abnormality, and the attenuation rate alarm information is generated. If the predicted attenuation rate is greater than the attenuation rate threshold, it can be determined that the battery capacity attenuation rate at the target time, i.e., at a certain time in the future, can be an abnormal value, and the attenuation rate early warning information is generated.
