Description

Technical Field

[0001] This application relates to the field of smart charging technology, and in particular to a charging management method and system based on a charging gun. Background Technology

[0002] With the increasing popularity of new energy vehicles, the frequency of use of charging piles and charging guns has increased significantly. Currently, the charging management of charging guns mainly relies on the power supply control of the charging pile; that is, after charging is completed, the charging pile stops supplying power, and the user can unplug the charging gun. However, existing charging management methods only focus on controlling the charging process and do not effectively regulate the return behavior of the charging gun.

[0003] In actual use, some users simply unplug the charging gun after charging is finished, without actively returning it to the charging station or designated storage location, resulting in the charging gun being carelessly discarded on the ground or hung next to the charging station.

[0004] Although some charging stations have adopted methods such as additional fees or credit points to regulate user behavior, these only punish the behavior of non-compliant individuals and do not effectively address the issue of charging guns not being returned to their proper places. As a result, charging guns are still randomly discarded on the ground or hung next to charging stations, affecting the aesthetics and efficiency of the charging stations and potentially damaging the charging guns. Overall, this is detrimental to the use of charging guns and there is still room for improvement. Summary of the Invention

[0005] To facilitate the use of charging guns, this application provides a charging management method and system based on charging guns.

[0006] Firstly, this application provides a charging management method based on a charging gun, employing the following technical solution:

[0007] A charging management method based on a charging gun, comprising:

[0008] Get the charging gun's return status;

[0009] When the charging gun's return state matches the preset waiting return state, the corresponding charging gun is defined as the charging gun to be focused on, and the charging focus position is obtained based on the charging gun to be focused on.

[0010] The charging focus area is determined based on the charging focus location, and the area waiting status is obtained based on the charging focus area.

[0011] When the area waiting state is consistent with the preset charging receiving state, the real-time vehicle location is obtained, and a vehicle guidance path is constructed and output based on the real-time vehicle location and the charging attention location.

[0012] The vehicle arrival time corresponding to the vehicle guidance path is determined based on the preset time matching relationship.

[0013] Within the time frame of the vehicle's arrival, monitor the charging gun's return status. When the charging gun changes from the waiting-to-return state to the preset effective use state, generate a reward settlement form based on the user corresponding to the current charging gun.

[0014] Optionally, after obtaining the vehicle's real-time location, the charging management method based on the charging gun further includes:

[0015] Within the clustered charging area, the number of vehicles charging is determined by counting based on their real-time location, and the number of charging attention is determined by counting based on the number of charging guns being monitored.

[0016] Determine whether the number of vehicles charging matches the number of vehicles being monitored for charging.

[0017] If the number of vehicles charging does not match the number of vehicles being charged, a difference matching signal will be output.

[0018] If the number of charging vehicles matches the number of charging-related concerns, a charging matching scheme will be generated by randomly pairing the real-time locations of the vehicles with the charging-related concerns.

[0019] In the charging matching scheme, a simulated driving path is constructed based on the matching information, and the simulated driving distance is determined based on each simulated driving path;

[0020] The individual evaluation parameters corresponding to the simulated driving distance are determined based on the preset evaluation matching relationship.

[0021] The evaluation parameters of the scheme are determined by calculation based on all individual evaluation parameters, and the charging matching scheme corresponding to the scheme with the largest evaluation parameter is defined as the effective matching scheme. The simulated driving path in the effective matching scheme is determined as the vehicle guidance path.

[0022] Optionally, after the individual evaluation parameters are determined, the charging management method based on the charging gun further includes:

[0023] On a single simulated driving path, determine the simulated overlapping path based on the path that overlaps with the other simulated driving paths;

[0024] The overlapping driving range of each vehicle on the simulated overlapping path is determined based on each simulated driving path.

[0025] The analysis of each overlapping driving section is used to determine the encounter time between the current vehicle and other vehicles on the simulated overlapping path.

[0026] The evaluation adjustment parameters corresponding to the vehicle encounter duration are determined based on the preset encounter matching relationship, and the individual evaluation parameters are updated based on the evaluation adjustment parameters and the individual evaluation parameters.

[0027] Optionally, after the scheme evaluation parameters are determined, the charging management method based on the charging gun may also include:

[0028] Determine whether there exists a charging matching scheme with at least two schemes having the same and largest evaluation parameters;

[0029] If there are no two charging matching schemes with the same and largest evaluation parameters, then the charging matching scheme corresponding to the largest evaluation parameter is defined as a valid matching scheme.

[0030] If there are at least two schemes with the same and largest evaluation parameters, then the charging matching scheme corresponding to the scheme with the largest evaluation parameters is defined as the alternative matching scheme.

[0031] Among the alternative matching schemes, the scheme evaluation parameters determined by the uncorrected and updated individual evaluation parameters are defined as reference evaluation parameters;

[0032] The reference evaluation parameter with the largest value is determined according to the preset sorting rules, and the alternative matching scheme corresponding to the reference evaluation parameter is defined as the valid matching scheme.

[0033] Optionally, after the differential matching signal is output, the charging management method based on the charging gun further includes:

[0034] Determine if the number of vehicles charging is greater than the number of vehicles under charging monitoring;

[0035] If the number of charging vehicles is not greater than the number of charging-related vehicles, then a missing attention signal will be output.

[0036] If the number of charging vehicles is greater than the number of charging-related concerns, then a vehicle selection combination will be constructed by randomly selecting from all vehicles based on the number of charging-related concerns.

[0037] In the vehicle selection combination, the evaluation parameters of the scheme are determined by analyzing the vehicle and the charging focus location, and the largest scheme evaluation parameter is defined as the representative evaluation parameter of the current vehicle selection combination.

[0038] The ranking rules determine the representative evaluation parameter with the largest value, and the vehicle selection combination corresponding to the representative evaluation parameter is defined as the reasonable vehicle combination. The vehicle guidance path is determined based on the simulated driving path of the effective matching scheme under the representative evaluation parameter corresponding to the reasonable vehicle combination.

[0039] Optionally, after addressing the missing signal output, the charging management method based on the charging gun further includes:

[0040] Get the connection interruption duration of each charging gun under interest;

[0041] The remaining breakage time is determined by calculating the difference between the preset permissible breakage time and the connection breakage time.

[0042] The analysis is performed based on the pre-set charging model to determine the predicted subsequent arrival time.

[0043] The charging guns with remaining fracture duration less than the predicted subsequent arrival time are defined as emergency charging guns, and the other charging guns with remaining fracture duration are defined as stable charging guns.

[0044] The number of emergency charging vehicles is determined by counting using the emergency charging gun, and it is then determined whether the number of emergency charging vehicles is less than the number of vehicles being charged.

[0045] If the number of emergency charging vehicles is not less than the number of charging vehicles, the charging guns are sorted according to the remaining interruption time from smallest to largest to determine the order of attention. In the order of attention, the number of charging guns and vehicles are selected from the front to the back for matching analysis to determine the effective matching scheme and construct the vehicle guidance path.

[0046] If the number of emergency charging vehicles is less than the number of charging vehicles, the difference between the number of emergency charging vehicles and the number of charging vehicles is used to determine the number of stable charging vehicles. The stable charging vehicles are then randomly selected from the stable charging vehicles based on the number of stable charging vehicles and combined with the emergency charging vehicles to construct a charging vehicle selection combination.

[0047] Analysis is performed under each charging gun selection combination to determine the scheme evaluation parameters, and the largest scheme evaluation parameter is determined to define the corresponding charging gun selection combination as the effective charging gun combination. The vehicle guidance path is determined based on the simulated driving path under the scheme evaluation parameters corresponding to the effective charging gun combination.

[0048] Optionally, the process may also include a step for determining the permissible duration of fracture, which includes:

[0049] The cumulative disconnection time is determined by summing the disconnection times of each connection of a single charging gun under interest.

[0050] The equipment wear parameters corresponding to the cumulative fracture time are determined based on the preset wear matching relationship;

[0051] The permissible fracture duration corresponding to the equipment wear parameters is determined based on a preset permissible matching relationship.

[0052] Secondly, this application provides a charging management system based on a charging gun, which adopts the following technical solution:

[0053] A charging management system based on a charging gun includes:

[0054] The acquisition module is used to acquire the charging gun's return status;

[0055] The processing module, connected to the acquisition and judgment modules, is used for information storage and processing;

[0056] The judgment module, connected to the acquisition and processing modules, is used for judging information.

[0057] When the judgment module determines that the charging gun's return state is consistent with the preset waiting return state, the processing module defines the corresponding charging gun as the charging gun to be focused on, and the acquisition module obtains the charging focus position based on the charging gun to be focused on.

[0058] The processing module determines the clustered charging area based on the charging interest location, and obtains the area waiting status based on the clustered charging area;

[0059] When the judgment module determines that the area waiting state is consistent with the preset charging receiving state, the acquisition module acquires the real-time vehicle location, and the processing module constructs and outputs the vehicle guidance path based on the real-time vehicle location and the charging attention location.

[0060] The processing module determines the vehicle arrival time corresponding to the vehicle guidance path based on the preset time matching relationship.

[0061] When the judgment module determines that the charging gun's return status has switched from the waiting return status to the preset valid use status within the time limit for the vehicle to arrive, the processing module outputs a reward settlement form based on the user corresponding to the current charging gun.

[0062] In summary, this application includes at least one of the following beneficial technical effects:

[0063] By locating the charging guns that have not been returned to their positions, they can be guided to the corresponding charging gun location when other users need to find a charging location, so that the charging guns can be picked up and used, which is beneficial to the overall use of the charging guns.

[0064] By analyzing the misplaced charging guns and vehicles, the matching relationship between the two is accurately determined, which facilitates charging for users while also organizing the misplaced charging guns. Attached Figure Description

[0065] Figure 1 This is a flowchart of a charging management method based on a charging gun.

[0066] Figure 2 This is a module flowchart of a charging management method based on a charging gun. Detailed Implementation

[0067] To make the purpose, technical solution, and advantages of this application clearer, the following is combined with Figures 1-2The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0068] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.

[0069] This application discloses a charging management method based on a charging gun, referring to... Figure 1 The charging management method based on a charging gun includes the following steps:

[0070] Step S100: Obtain the charging gun's return status.

[0071] The charging gun return status refers to whether the charging gun has been placed back into its corresponding slot, or whether the charging gun has been carelessly discarded on the ground.

[0072] Step S101: When the charging gun's return state matches the preset waiting return state, define the corresponding charging gun as the charging gun to be focused on, and obtain the charging focus position based on the charging gun.

[0073] The "waiting to return to its original position" state refers to the state when a charging gun is randomly discarded on the ground. When the charging gun's "return to its original position" state is consistent with the "waiting to return to its original position" state, it indicates that there is a discarded charging gun that needs to be processed and analyzed. At this time, a "charging gun of interest" is defined to identify and distinguish different charging guns. The "charging gun of interest" location refers to the location where the charging gun of interest is installed.

[0074] Step S102: Determine the clustered charging area based on the charging attention location, and obtain the area waiting status based on the clustered charging area.

[0075] The clustered charging area refers to the overall charging area where the focus charging gun is installed. It is the area where other charging guns located in the same charging area as the focus charging gun need to be located. In other words, it is the area where other users can choose the location of the charging gun when they are charging. Generally, this area is the parking lot area. The area waiting status refers to whether there are vehicles entering the current area that need to be charged. The status information can be obtained by installing monitoring equipment at the corresponding entrances and exits.

[0076] Step S103: When the area waiting state is consistent with the preset charging receiving state, obtain the real-time vehicle location, construct a vehicle guidance path based on the real-time vehicle location and the charging attention location, and output it.

[0077] The charging reception status is the area waiting state set by staff when a vehicle enters the area and needs to use the charging guns in the current charging cluster. The real-time vehicle location is the vehicle's position within the charging cluster, which can be obtained by locating the vehicle from the position point in the area waiting state. The vehicle guidance path is the shortest movement path that a vehicle can take from its real-time location to the charging location of interest within the charging cluster. This path can be determined through data analysis using the shortest path rule. The output of the vehicle guidance path can be indicated by illuminating the indicator installed on the ground or above the charging cluster to guide the driver.

[0078] Step S104: Determine the vehicle arrival time corresponding to the vehicle guidance path according to the preset time matching relationship.

[0079] The vehicle arrival time is the maximum time required for a vehicle to travel according to the vehicle guidance path. Different vehicle guidance paths have different distances, and the corresponding vehicle arrival time will also be different. The time matching relationship between the two is determined by the staff in advance through multiple tests.

[0080] Step S105: Within the time limit for the vehicle to arrive, when the charging gun's return status changes from the waiting return status to the preset valid use status, a reward settlement form is output according to the user corresponding to the current charging gun.

[0081] The effective usage status is defined by the staff as the status when the charging gun is connected to the vehicle or when it is returned to its slot. When the charging gun's return status changes from the waiting-to-return state to the effective usage state within the time frame of the vehicle's arrival, it indicates that the current user has retrieved the discarded charging gun, thus changing the fact that the charging gun was not returned to its original position, which is beneficial for the use of the charging gun. At this time, a reward settlement form can be appropriately generated to reward the current user. The specific reward settlement form is determined and set by the staff.

[0082] After obtaining the vehicle's real-time location, the charging management method based on the charging gun also includes:

[0083] Step S200: Count the number of vehicles charging within the charging cluster area based on their real-time location, and count the number of charging attention based on the number of charging guns being monitored.

[0084] The number of vehicles being charged refers to the number of vehicles detected within the clustered charging area, which is also the number of vehicles that need to use the charging gun. The number of charging attention refers to the number of charging guns that are being paid attention to within the clustered charging area.

[0085] Step S201: Determine whether the number of charging vehicles matches the number of charging-related concerns.

[0086] The purpose of this judgment is to determine whether the vehicle and the charging gun can be matched one by one.

[0087] Step S2011: If the number of charging vehicles does not match the number of charging targets, output a difference matching signal.

[0088] When the number of vehicles being charged does not match the number of vehicles being charged, it means that it is impossible to match each vehicle with a charging gun. In this case, a difference matching signal is output to identify the situation for subsequent analysis.

[0089] Step S2012: If the number of charging vehicles matches the number of charging-related concerns, then a charging matching scheme is generated by randomly pairing the real-time vehicle locations with the charging-related concerns locations.

[0090] When the number of charging vehicles matches the number of charging interest groups, it means that vehicles can be matched one-to-one with charging guns, which can guide vehicles to process each charging gun of interest. At this time, random matching of vehicles and charging guns is performed to construct a charging matching scheme, which is convenient for subsequent analysis.

[0091] Step S202: Construct a simulated driving path based on the matching information in the charging matching scheme, and determine the simulated driving distance based on each simulated driving path.

[0092] The simulated driving path is the path that guides the movement between the matched vehicle and the charging gun. The path determination rules are the same as those for the vehicle guidance path mentioned above. The simulated driving distance is the path distance of the simulated driving path.

[0093] Step S203: Determine the individual evaluation parameters corresponding to the simulated driving distance based on the preset evaluation matching relationship.

[0094] The individual evaluation parameter is a parameter value that reflects the rationality of the currently determined simulated driving path. The larger the value, the more reasonable the set simulated driving path is. When the simulated driving distance is smaller, it means that the vehicle is easier to move to the charging attention location to process the charging gun. At this time, the corresponding individual evaluation parameter is larger. The evaluation matching relationship between the two is determined in advance by the staff and recorded and stored.

[0095] Step S204: Calculate and determine the scheme evaluation parameters based on all individual evaluation parameters, define the charging matching scheme corresponding to the scheme with the largest scheme evaluation parameter as the effective matching scheme, and determine the simulated driving path in the effective matching scheme as the vehicle guidance path.

[0096] The scheme evaluation parameter is a parameter value that reflects the rationality of the currently determined charging matching scheme. The larger the value, the easier it is for the vehicle to process the charging gun under the current scheme. The scheme evaluation parameter can be determined by averaging all individual evaluation parameters. At this time, the charging matching scheme corresponding to the largest scheme evaluation parameter is the most reasonable charging processing scheme. Therefore, it is defined as the effective matching scheme to determine the corresponding vehicle guidance path.

[0097] After the individual evaluation parameters are determined, the charging management method based on the charging gun also includes:

[0098] Step S300: Determine the simulated overlapping path on a single simulated driving path based on the path that overlaps with the other simulated driving paths.

[0099] The simulated overlapping path is the path where a single simulated driving path overlaps with the other simulated driving paths.

[0100] Step S301: Determine the overlapping driving range of each vehicle on the simulated overlapping path based on each simulated driving path.

[0101] The overlapping travel interval is the time interval in which each vehicle travels on the currently determined simulated overlapping path. It can be determined by setting a fixed vehicle speed and then calculating based on the distance conditions.

[0102] Step S302: Analyze each overlapping driving section to determine the encounter time between the current vehicle and other vehicles on the simulated overlapping path.

[0103] Vehicle encounter duration is the total time that the vehicle being analyzed will encounter other vehicles during its movement.

[0104] Step S303: Determine the evaluation adjustment parameters corresponding to the vehicle encounter duration based on the preset encounter matching relationship, and calculate and update the individual evaluation parameters based on the evaluation adjustment parameters and the individual evaluation parameters.

[0105] The evaluation adjustment parameter is a parameter value used to adjust the individual evaluation parameters. Different vehicle encounter durations indicate different levels of vehicle driving convenience. The shorter the vehicle encounter duration, the less time the vehicles have to meet, which means it is easier for the vehicles to carry out driving and charging. Therefore, the corresponding evaluation adjustment parameter is smaller. The encounter matching relationship between the two is determined by the staff in advance through multiple tests. By subtracting the evaluation adjustment parameter from the individual evaluation parameter, the individual evaluation parameter can be updated, thereby improving the accuracy of the determination of the individual evaluation parameter.

[0106] After the evaluation parameters of the scheme are determined, the charging management method based on the charging gun also includes:

[0107] Step S400: Determine whether there are at least two schemes with the same and largest charging matching parameters.

[0108] The purpose of this judgment is to determine whether there are multiple charging matching schemes that meet the requirements, so as to identify the only valid matching scheme.

[0109] Step S4001: If there are no two schemes with the same and largest evaluation parameters, then the charging matching scheme corresponding to the scheme with the largest evaluation parameters is defined as a valid matching scheme.

[0110] When there are no two charging matching schemes with the same and largest evaluation parameters, it means that there is only one charging matching scheme that meets the requirements. In this case, it can be determined as a valid matching scheme.

[0111] Step S4002: If there are at least two schemes with the same and largest evaluation parameters, then the charging matching scheme corresponding to the largest evaluation parameter is defined as the alternative matching scheme.

[0112] When there are at least two charging matching schemes with the same and largest evaluation parameters, it indicates that there are multiple charging matching schemes that meet the requirements. In this case, they are defined as alternative matching schemes to distinguish different charging matching schemes and facilitate subsequent analysis.

[0113] Step S401: Define the scheme evaluation parameters determined by the uncorrected and unupdated individual evaluation parameters in the alternative matching schemes as reference evaluation parameters.

[0114] Define reference evaluation parameters to identify parameters for evaluating the reasonableness of a path when only distance is considered, so as to facilitate subsequent analysis.

[0115] Step S402: Determine the reference evaluation parameter with the largest value according to the preset sorting rules, and define the alternative matching scheme corresponding to the reference evaluation parameter as the valid matching scheme.

[0116] The sorting rule is a method set by the staff to sort numerical values, such as the bubble sort method. The sorting rule can determine the reference evaluation parameter with the largest value. That is, the corresponding alternative matching scheme is the most reasonable when only considering the distance. Therefore, it can be defined as a valid matching scheme.

[0117] After the differential matching signal is output, the charging management method based on the charging gun also includes:

[0118] Step S500: Determine whether the number of charging vehicles is greater than the number of charging-related vehicles.

[0119] The purpose of the judgment is to determine whether each charging gun in the current area has a corresponding vehicle, that is, whether all the charging guns in the current area can be processed.

[0120] Step S5001: If the number of charging vehicles is not greater than the number of charging attention items, then output a attention missing signal.

[0121] When the number of charging vehicles is not greater than the number of charging attention items, it indicates that not all the attention items can be guided and processed. In this case, an attention missing signal is output to identify the situation for subsequent analysis.

[0122] Step S5002: If the number of charging vehicles is greater than the number of charging interest targets, then randomly select from all vehicles based on the number of charging interest targets to construct a vehicle selection combination.

[0123] When the number of charging vehicles exceeds the number of charging attention points, it means that all the attention charging guns can be processed. At this time, there are redundant vehicles, and it is necessary to further select the vehicles that are actually guided to the attention charging guns. Therefore, a vehicle selection combination is constructed to facilitate the matching analysis between vehicles and attention charging guns.

[0124] Step S501: Analyze the vehicle and charging location in the vehicle selection combination to determine the scheme evaluation parameters, and define the largest scheme evaluation parameter as the representative evaluation parameter of the current vehicle selection combination.

[0125] Define the evaluation parameters to determine the most reasonable combination of vehicles under the current selection, which will facilitate subsequent analysis.

[0126] Step S502: Determine the representative evaluation parameter with the largest value according to the sorting rules, define the vehicle selection combination corresponding to the representative evaluation parameter as the reasonable vehicle combination, and determine the vehicle guidance path according to the simulated driving path under the effective matching scheme corresponding to the representative evaluation parameter of the reasonable vehicle combination.

[0127] The sorting rules determine the evaluation parameter with the largest value, which means that the current vehicle selection combination is the most convenient for processing all charging guns. Therefore, it is defined as a reasonable vehicle combination for differentiation. At this time, based on the specific matching situation under the reasonable vehicle combination, the vehicle guidance path required for each vehicle can be determined, thereby enabling the charging gun to process the vehicles.

[0128] After addressing the missing signal output, the charging management method based on the charging gun also includes:

[0129] Step S600: Obtain the connection interruption duration of each charging gun of interest.

[0130] The connection interruption duration is the duration during which the currently monitored charging gun is not in use or not in the gun slot, that is, the duration during which the monitored charging gun is currently defined as a monitored charging gun.

[0131] Step S601: Calculate the difference between the preset permissible fracture duration and the connection fracture duration to determine the remaining fracture duration.

[0132] The permitted breakage duration is the maximum allowable connection breakage duration set by the staff when the charging gun will not cause significant wear and tear. The remaining breakage duration is the permitted breakage duration minus the actual connection breakage duration.

[0133] Step S602: Analyze the preset charging model to determine the predicted subsequent arrival time.

[0134] The large-scale charging model is a predictive model that is set up in advance by staff to predict the charging status of vehicles. Through this model, the arrival time of vehicles that will enter the current area for charging can be predicted, and the subsequent arrival time is the time that vehicles that will enter the current area for charging will need to wait.

[0135] Step S603: Define the charging guns with remaining fracture duration less than the predicted subsequent arrival time as emergency charging guns, and define the other charging guns as steady charging guns.

[0136] We define emergency charging guns and stable charging guns to differentiate between charging guns of different levels of concern, which facilitates subsequent analysis.

[0137] Step S604: Count according to the emergency charging gun to determine the number of emergency charges, and determine whether the number of emergency charges is less than the number of charging vehicles.

[0138] The number of emergency charging guns is the number of emergency charging guns determined. The purpose of this determination is to know whether the most urgent charging guns can be processed.

[0139] Step S6041: If the number of emergency charging vehicles is not less than the number of charging vehicles, the charging guns are sorted according to the remaining interruption time from smallest to largest to determine the order of attention. The charging guns and vehicles are selected from the front to the back of the order of attention to perform matching analysis to determine the effective matching scheme and construct the vehicle guidance path.

[0140] When the number of emergency charging guns is not less than the number of charging vehicles, it indicates that the current emergency charging guns cannot be fully processed. Therefore, it is necessary to determine the specific emergency charging guns to be processed. The order of attention is the order in which the charging guns are sorted from smallest to largest according to the remaining interruption time. By matching and analyzing the charging guns that are at the top of the attention order with the vehicles, the processing status of the charging guns that need the most processing can be analyzed.

[0141] Step S6042: If the number of emergency charging vehicles is less than the number of charging vehicles, the difference between the number of emergency charging vehicles and the number of charging vehicles is used to calculate the number of stable charging vehicles. The number of stable charging vehicles is then randomly selected from the stable charging guns and combined with the emergency charging guns to construct a charging gun selection combination.

[0142] When the number of emergency charging guns is less than the number of charging vehicles, it means that all emergency charging guns can be processed, and some stable charging guns can also be processed, which requires further analysis. The number of stable supplementary charging guns is the number of stable charging guns that can be processed, which is determined by subtracting the number of emergency charging guns from the number of charging vehicles. The charging gun selection combination is the total number of charging guns constructed after randomly selecting stable charging guns.

[0143] Step S605: Analyze each charging gun selection combination to determine the scheme evaluation parameters, and determine the largest scheme evaluation parameter to define the corresponding charging gun selection combination as the effective charging gun combination, and determine the vehicle guidance path based on the simulated driving path under the scheme evaluation parameters corresponding to the effective charging gun combination.

[0144] By analyzing the scheme evaluation parameters of all charging selection combinations, the scheme evaluation parameter with the largest value can be determined. The corresponding charging gun selection combination is the one with the best overall processing effect. Therefore, it is defined as the effective charging gun combination to distinguish different charging gun selection combinations, so that the guidance path of each vehicle can be determined based on the current effective charging gun combination.

[0145] It also includes a step for determining the permissible fracture duration, which includes:

[0146] Step S700: Sum the connection break times of each individual charging gun to determine the cumulative break time.

[0147] The cumulative disconnection duration is the duration defined as the duration of the charging gun being monitored since it was put into use or since the last maintenance. It can be determined by adding up the disconnection durations of all connections.

[0148] Step S701: Determine the equipment wear parameters corresponding to the cumulative fracture time based on the preset wear matching relationship.

[0149] The equipment wear parameters reflect the wear caused by the charging gun being carelessly discarded. Different cumulative fracture durations indicate different durations of careless disposal of the charging gun, and the corresponding equipment wear parameters are also different. The wear matching relationship between the two is determined by the staff through multiple tests in advance, which will not be elaborated here.

[0150] Step S702: Determine the permissible fracture duration corresponding to the equipment wear parameters based on the preset permissible matching relationship.

[0151] Different equipment wear parameters indicate different specific wear conditions of the charging gun. At this time, the allowable wear time of the charging gun is also different, that is, the permissible fracture time is different. The permissible matching relationship between the two is determined by the staff in advance through multiple tests. It is necessary to ensure that the larger the equipment wear parameter, the smaller the corresponding permissible fracture time.

[0152] Reference Figure 2 Based on the same inventive concept, embodiments of the present invention provide a charging management system based on a charging gun, comprising:

[0153] The acquisition module is used to acquire the charging gun's return status;

[0154] The processing module, connected to the acquisition and judgment modules, is used for information storage and processing;

[0155] The judgment module, connected to the acquisition and processing modules, is used for judging information.

[0156] When the judgment module determines that the charging gun's return state is consistent with the preset waiting return state, the processing module defines the corresponding charging gun as the charging gun to be focused on, and the acquisition module obtains the charging focus position based on the charging gun to be focused on.
