Abstract
Description
Technical Field
[0001] This application relates to the field of charging station technology, and in particular to a management method, system and storage medium for new energy charging stations. Background Technology
[0002] With the rapid development of new energy technologies, more and more new energy vehicles are appearing in the public eye. Since their main energy source is electricity, charging stations are deployed in certain areas to facilitate the normal operation of new energy vehicles. Several charging piles are installed in the charging stations to facilitate vehicle charging.
[0003] Currently, when a vehicle needs charging, drivers typically search for charging station locations on map software to choose the nearest station, or rely on their knowledge of charging station distribution to select the desired station. When a charging station detects a vehicle approaching, if all charging stations are available, the vehicle can enter and charge. If all charging stations are busy, the vehicle cannot enter and must wait or find another charging station. This undoubtedly leads to higher utilization rates for charging stations in high-traffic areas and lower utilization rates in low-traffic areas, resulting in some charging stations being congested while others are idle, indicating an unreasonable allocation of charging stations. Summary of the Invention
[0004] To improve the rationality of charging station allocation, this application provides a new energy charging station management method, system, and storage medium.
[0005] Firstly, this embodiment provides a method for managing new energy charging stations, the method comprising: Receive idle orders from each charging station and broadcast the idle orders to new energy vehicles; Receive selected idle orders and feedback information selected by new energy vehicles, obtain associated charging station information associated with the selected idle orders, and determine the locked idle orders and the adjusted idle orders among the selected idle orders based on the associated charging station information, the feedback information and the selected idle orders; Based on the idle orders and the locked idle orders, generate alternative idle orders corresponding to the adjusted idle orders, and send the alternative idle orders to the adjusted new energy vehicles corresponding to the adjusted idle orders; Receive confirmation information sent by the adjusted new energy vehicle, and generate a confirmed idle order corresponding to the adjusted new energy vehicle based on the confirmation information; The locked idle orders and the confirmed idle orders are sent to the corresponding charging stations to adjust the idle orders of the charging stations.
[0006] In some embodiments, the idle order includes several idle sub-orders, each idle order corresponding to an order location, and the number of idle sub-orders is equal to the total number of sub-orders. The selected idle order includes several selected idle sub-orders, each selected idle sub-order corresponding to the same order location, and the number of sub-orders is equal to the number of selected sub-orders. The feedback information includes the waiting time to reach the charging station corresponding to the selected idle sub-order. The associated charging station information includes the conversion time required for each working charging pile in the associated charging station to become idle. Determining the locked idle orders and the adjusted idle orders among the selected idle orders based on the associated charging station information, the feedback information, and the selected idle orders includes: Determine whether the number of selected sub-orders corresponding to the same order position is greater than the total number of sub-orders. If not, determine the selected idle sub-orders corresponding to the order position as locked idle sub-orders. If the number of selected sub-orders is greater than the total number of sub-orders, obtain the number of super-orders that are greater than the total number of sub-orders. Based on the number of super-orders, the conversion time in the associated charging station information corresponding to the order location, and the waiting time in the feedback information corresponding to the order location, determine the locked idle sub-orders and adjusted idle sub-orders corresponding to the order location. The locked idle orders include the locked idle sub-orders corresponding to each order location, and the adjusted idle orders include the adjusted idle sub-orders corresponding to each order location.
[0007] In some embodiments, determining the locked idle sub-orders and adjusted idle sub-orders corresponding to the order location based on the excess order quantity, the conversion time in the associated charging station information corresponding to the order location, and the waiting time in the feedback information corresponding to the order location includes: The conversion time corresponding to the same order location is sorted in ascending order to obtain a conversion time sequence, and the waiting time is sorted in ascending order to obtain a waiting time sequence; Determine whether the conversion time series is shorter than the waiting time series. If so, use preset big data to supplement the end of the conversion time series to obtain a new conversion time series, so that the conversion time series and the waiting time series contain the same number of times. Determine reference positions in the transition time series and waiting time series where the transition time is greater than the waiting time, in order from the beginning to the end. Obtain the number of positions from the reference position to the beginning, and determine whether the number of positions is less than the number of excess orders. If it is less than, the sub-order corresponding to the waiting time at the position before the reference position is determined as the locked idle sub-order corresponding to the order position, and the sub-order corresponding to the waiting time at the reference position and the position after the reference position is determined as the adjusted idle sub-order corresponding to the order position. If it is not less than, the sub-orders corresponding to the waiting times of the preceding number of orders in the waiting time sequence are determined as the locked idle sub-orders corresponding to the order position, wherein there are no corresponding adjusted idle sub-orders for the order position.
[0008] In some embodiments, generating alternative idle orders corresponding to the adjusted idle orders based on the idle orders and the locked idle orders includes: The idle orders and the locked idle orders are plotted on the same two-dimensional coordinate system to obtain the distribution information of the locked idle orders among the idle orders; Obtain the sparse regions in the distribution information and the sparse charging stations in the sparse regions, and determine the unselected orders in the idle orders sent by the sparse charging stations as the alternative idle orders corresponding to the adjusted idle orders.
[0009] In some embodiments, the confirmation information includes confirmation sub-information sent by each adjusted new energy vehicle, each confirmation sub-information including a self-selected idle order or vehicle location selected from the alternative idle orders, and generating the confirmed idle order corresponding to the adjusted new energy vehicle based on the confirmation information includes: Determine whether the determined sub-information contains any self-selected idle orders. If so, determine any one of the self-selected idle orders as the confirmed idle order corresponding to the adjustment of the new energy vehicle. If not, the order closest to the vehicle's location among the candidate idle orders will be determined as the confirmed idle order corresponding to the new energy vehicle adjustment.
[0010] In some embodiments, the method further includes: The electricity consumption of each charging station is obtained, and the electricity consumption is substituted into a preset electricity price relationship to obtain the charging unit price corresponding to the charging station. The charging unit price is then sent to the new energy vehicle.
[0011] In some embodiments, the method further includes: The cumulative working time and single working time of each charging pile in each charging station are obtained, and the cumulative working time and single working time are substituted into a preset maintenance model to obtain the maintenance information of the charging pile.
[0012] In some embodiments, the method further includes: The working percentage of charging piles in each charging station is obtained, and it is determined whether the working percentage exceeds the preset percentage. If it does, a charging power adjustment signal is sent to the new energy vehicle corresponding to each working charging pile. Receive adjustment information sent by the new energy vehicle, and determine the actual charging power of the new energy vehicle based on the adjustment information.
[0013] Secondly, this embodiment provides a new energy charging station management system, the system including: a charging station broadcast module, a charging station initial management module, a charging station re-management module, and a charging station adjustment module; wherein, The charging station broadcasting module is used to receive idle orders sent by each charging station and broadcast the idle orders to new energy vehicles; The initial management module for charging stations is used to receive selected idle orders and feedback information selected by new energy vehicles, obtain the associated charging station information associated with the selected idle orders, and determine the locked idle orders and the adjusted idle orders among the selected idle orders based on the associated charging station information, the feedback information and the selected idle orders. The charging station re-management module is used to generate alternative idle orders corresponding to the adjusted idle orders based on the idle orders and the locked idle orders, and send the alternative idle orders to the adjusted new energy vehicles corresponding to the adjusted idle orders; receive confirmation information sent by the adjusted new energy vehicles, and generate confirmed idle orders corresponding to the adjusted new energy vehicles based on the confirmation information; The charging station adjustment module is used to send the locked idle orders and the confirmed idle orders to the corresponding charging stations to adjust the idle orders of the charging stations.
[0014] Thirdly, this embodiment provides a computer-readable storage medium storing a computer program that can run on a processor, wherein the computer program, when executed by the processor, implements a new energy charging station management method as described in the first aspect.
[0015] By employing the above method, this application first receives idle orders from each charging station and broadcasts these orders to the new energy vehicles. This allows each new energy vehicle that has established a communication connection with the management terminal to understand the availability of charging piles at each charging station in the city, providing more charging stations for the new energy vehicles to choose from and offering a basis for subsequent allocation of charging services.
[0016] Then, it receives the selected idle orders and feedback information from new energy vehicles, obtains the associated charging station information of the selected idle orders, and determines the locked idle orders and the adjusted idle orders based on the associated charging station information, feedback information, and selected idle orders. Based on the idle orders and locked idle orders, it generates alternative idle orders corresponding to the adjusted idle orders and sends these alternative idle orders to the corresponding new energy vehicles. It receives confirmation information from the adjusted new energy vehicles and generates confirmed idle orders based on this information. Finally, it sends the locked idle orders and confirmed idle orders to the corresponding charging stations to adjust their idle orders. This system can automatically and more rationally allocate charging stations, reducing situations where some charging stations are congested while others are idle. Furthermore, it makes charging station information transparent, allowing users to quickly find available charging stations and reducing charging wait times. Attached Figure Description

[0022] To better understand the purpose, technical solutions, and advantages of this application, it has been described and illustrated below with reference to the accompanying drawings and embodiments. However, those skilled in the art should understand that this application can be implemented without these details. It will be apparent to those skilled in the art that various modifications can be made to the embodiments disclosed in this application, and the general principles defined in this application can be applied to other embodiments and application scenarios without departing from the principles and scope of this application. Therefore, this application is not limited to the illustrated embodiments, but is consistent with the broadest scope claimed in this application.
[0023] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.
[0024] Figure 1 This is a flowchart illustrating a new energy charging station management method provided in this application. Figure 1 As shown, a management method for new energy charging stations includes the following steps: Step S100: Receive idle orders sent by each charging station and broadcast the idle orders to the new energy vehicles.
[0025] The specific application scenarios for this application can be urban public charging stations, highway service area charging facilities, or charging stations within urban enterprise parks. Taking urban public charging stations as an example, this application describes the application from the management end, which has communication connections with various charging stations in the city and with the new energy vehicles traveling in the city. Specifically, the management end can directly communicate with each charging station in the city, or it can indirectly communicate with charging stations located far from the management end by using intermediate charging stations for information transmission. Further limitations are not made regarding the communication connection between the management end and the various charging stations in the city. The new energy vehicles traveling in the city are connected to a network, and communication between the management end and the new energy vehicles traveling in the city can be achieved through the network.
[0026] When the management terminal has the task of managing new energy charging stations, it first establishes communication connections with each charging station and the new energy vehicles in motion. Then, each charging station sends idle orders to the management terminal based on the operational status of its charging piles. This allows the management terminal to receive idle orders from each charging station. An idle order indicates which charging piles at the charging station are idle, i.e., not connected to a new energy vehicle. Each charging station corresponds to one idle order, and each idle order corresponds to an order location, i.e., the location of the charging station. Each idle order includes several idle sub-orders, and each idle sub-order corresponds to one idle charging pile at the charging station. The number of idle sub-orders in each idle order is the total number of sub-orders, i.e., the number of idle charging piles at that charging station.
[0027] After receiving idle orders from each charging station, the management terminal sends all the received idle orders to the new energy vehicles with established communication connections. This broadcasts the idle orders to the new energy vehicles, allowing each new energy vehicle with a communication connection to the management terminal to understand the availability of charging piles at each charging station in the city. This provides new energy vehicles with more charging stations to choose from and provides a basis for subsequent allocation of charging services for new energy vehicles.
[0028] Step S200: Receive the selected idle orders and feedback information selected by the new energy vehicle, obtain the associated charging station information associated with the selected idle orders, and determine the locked idle orders and the adjusted idle orders among the selected idle orders based on the associated charging station information, feedback information and selected idle orders.
[0029] The aforementioned selected idle orders indicate which charging stations the new energy vehicle has chosen from all the idle orders broadcast in step S100. Feedback information represents information sent by the new energy vehicle to the management terminal. The management terminal can receive the selected idle orders and feedback information from the new energy vehicle through a communication connection. Each selected idle order includes several selected idle sub-orders, each sub-order corresponding to a charging station. The location of the charging station is the order location corresponding to that sub-order. Each selected idle sub-order contains several sub-orders, each sub-order indicating which new energy vehicle selected that charging station. The number of sub-orders in each selected idle sub-order is the number of selected sub-orders. The feedback information includes the waiting time to reach the charging station corresponding to the selected idle sub-order, i.e., the time required for the new energy vehicle to reach the selected charging station from its current location.
[0030] The aforementioned associated charging station information represents the status of each charging pile within the associated charging station. This information includes the conversion time required for each working charging pile within the associated charging station to transition to an idle state; that is, the time required for each working charging pile within the associated charging station to transition to an idle state. The management terminal can obtain the associated charging station information for selected idle orders by sending a retrieval command to each charging station. Subsequently, the management terminal selects which orders from the selected idle orders are confirmed as executable (i.e., locking idle orders) and which orders need to be adjusted and are not executable (i.e., adjusting idle orders). Figure 2 This application provides a flowchart of a method for determining which idle orders need to be locked and which need to be adjusted from the selected idle orders, based on associated charging station information, feedback information, and selected idle orders. Figure 2 As shown, determining the locked idle orders and the adjusted idle orders among the selected idle orders based on associated charging station information, feedback information, and selected idle orders includes the following steps: Step S201: Determine whether the number of selected sub-orders corresponding to the same order position is greater than the total number of sub-orders. If not, determine the selected idle sub-orders corresponding to the order position as locked idle sub-orders.
[0031] Step S202: If the number of selected sub-orders is greater than the total number of sub-orders, obtain the number of super-orders that are greater than the total number of sub-orders. Based on the number of super-orders, the conversion time in the associated charging station information corresponding to the order location, and the waiting time in the feedback information corresponding to the order location, determine the locked idle sub-orders and adjusted idle sub-orders corresponding to the order location. The locked idle orders include the locked idle sub-orders corresponding to each order location, and the adjusted idle orders include the adjusted idle sub-orders corresponding to each order location.
[0032] Each order location corresponds to the number of selected sub-orders and the total number of sub-orders. Taking an order location as an example, the difference or quotient between the number of selected sub-orders and the total number of sub-orders for this order location is used to determine whether the number of selected sub-orders is greater than the total number of sub-orders.
[0033] If the number of selected sub-orders corresponding to this order location is not greater than the total number of sub-orders, it indicates that all selected idle sub-orders corresponding to this order location have been executed. This will also enable the charging station corresponding to this order location to serve these sub-orders without saturating the workload of the charging station. In this case, the selected idle sub-orders corresponding to this order location are determined as locked idle sub-orders corresponding to this order location.
[0034] If the number of selected sub-orders corresponding to a given order location is greater than the total number of sub-orders, it indicates that all selected idle sub-orders at that location have been executed. This may prevent the charging station at that location from serving all sub-orders. To further determine whether the charging station at that location can serve all sub-orders, the number of selected sub-orders at that location needs to be subtracted from the total number of sub-orders to obtain the excess order quantity, which is the number of times the number of selected sub-orders at that location exceeds the total number of sub-orders. Subsequently, based on the excess order quantity, the conversion time in the associated charging station information for that location, and the waiting time in the feedback information for that location, the locked and adjusted idle sub-orders for that location are determined. The process for locking and adjusting idle sub-orders for other order locations is the same as the process described above, and will not be repeated here. The process of determining the locked and adjusted idle sub-orders for a given order location based on the excess order quantity, the conversion time in the associated charging station information, and the waiting time in the feedback information for that location includes the following steps: Step S202-1: Sort the conversion time corresponding to the same order location in ascending order to obtain the conversion time series, and sort the waiting time in ascending order to obtain the waiting time series.
[0035] Step S202-2: Determine whether the converted time series is shorter than the waiting time series. If so, use preset big data to supplement the end of the converted time series to obtain a new converted time series, so that the converted time series and the waiting time series contain the same number of times.
[0036] Step S202-3: Determine the reference positions in the conversion time series and waiting time series where the conversion time is greater than the waiting time, in order from the beginning to the end. Obtain the number of positions from the reference position to the beginning and determine whether the number of positions is less than the number of orders exceeding the limit.
[0037] Step S202-4: If the time is less than the reference position, the sub-orders corresponding to the waiting time at the position before the reference position are determined as locked idle sub-orders corresponding to the order position, and the sub-orders corresponding to the waiting time at the reference position and the position after the reference position are determined as adjusted idle sub-orders corresponding to the order position.
[0038] Step S202-5: If it is not less than, determine the sub-orders corresponding to the waiting time of the number of orders above the first in the waiting time sequence as the locked idle sub-orders corresponding to the order positions, where there are no corresponding adjusted idle sub-orders for the order positions.
[0039] Each order location corresponds to several selected idle sub-orders, each selected idle sub-order corresponds to a waiting time, each order location corresponds to several charging stations, and each charging station corresponds to a conversion time. In other words, each order location has several conversion times and several waiting times. Taking one order location as an example, sorting all the conversion times corresponding to this order location in ascending order yields a conversion time sequence, where each conversion time corresponds to one location. Similarly, sorting all the waiting times corresponding to this order location in ascending order yields a waiting time sequence, where each waiting time corresponds to one location.
[0040] The lengths of the waiting time series and the transformation time series may differ. In this case, the number of waiting times contained in the waiting time series can be compared with the number of transformation times contained in the transformation time series to determine if the transformation time series is shorter than the waiting time series. If the number of transformation times contained in the transformation time series is less than the number of waiting times contained in the waiting time series, it indicates that the transformation time series is shorter. To facilitate subsequent comparisons of the transformation time and waiting time, and to determine which sub-orders among the selected idle sub-orders corresponding to this order position can be locked as idle sub-orders and which need to be adjusted as idle sub-orders, the transformation time series needs to be lengthened to obtain a new transformation time series with the same length as the waiting time series. This is achieved by supplementing the end of the transformation time series with a preset large dataset to obtain a new transformation time series, ensuring that the transformation time series and the waiting time series contain the same number of times. The preset large dataset can be a near-infinite dataset or larger than the maximum historical waiting time, ensuring that the preset large dataset is definitely greater than any waiting time in the waiting time series. For example, if a conversion time series is [1.1,2,2.3,4,5.5] and a waiting time series is [1,2.4,3,4.5,5,6], then the conversion time series needs to be supplemented to obtain a new conversion time series [1.1,2,2.3,4,5.5,10000].
[0041] Then, the waiting time series and the conversion time series of the same length are sequentially compared from the beginning to the end. The comparison continues until the conversion time is greater than the waiting time, at which point the comparison stops and the conversion time and waiting time at the next position are determined. This position is then designated as a reference position. The position number of this reference position in the sequence is then subtracted by a certain number to determine the distance from the beginning of the sequence. Finally, this distance is compared with the number of excess orders.
[0042] If the number of available positions is less than the number of excess orders, it means that only a certain number of available positions among the selected idle sub-orders corresponding to that order position can be identified as locked idle sub-orders. The excess orders, due to the difference in the number of available positions, need to be identified as adjusted idle sub-orders. Specifically, the sub-orders corresponding to the waiting time of positions preceding the reference position are identified as locked idle sub-orders for that order position, and the sub-orders corresponding to the waiting time of the reference position and positions following the reference position are identified as adjusted idle sub-orders for that order position.
[0043] If the number of available locations is not less than the number of excess orders, it indicates that among the selected idle sub-orders corresponding to that location, a number of selected idle sub-orders exceeding the number of orders can be identified as locked idle sub-orders. This means that the sub-orders corresponding to the waiting times of the first number of excess orders in the waiting time sequence are identified as locked idle sub-orders for that location. There are no corresponding adjusted idle sub-orders for that location. If the number of selected sub-orders for a location exceeds the total number of sub-orders, the locked and adjusted idle sub-orders for other locations are determined in the same way as those for the location described above, and will not be elaborated further here. This way, if it is determined that the charging station cannot currently meet the charging needs of all new energy vehicles choosing it, the arrival time of these vehicles can be further considered. Without encountering situations where new energy vehicles arrive at the charging station but cannot charge, the utilization efficiency of the charging station can be improved, and the demand for new energy vehicles can be minimized, providing convenience for them. In other words, there is no situation where an excessive number of vehicles are allocated to the charging station.
[0044] Step S300: Based on the idle orders and the locked idle orders, generate alternative idle orders corresponding to the adjusted idle orders, and send the alternative idle orders to the adjusted new energy vehicles corresponding to the adjusted idle orders.
[0045] When there are idle orders to be adjusted, it indicates that some new energy vehicles have charging needs, but there is no charging station that can provide charging services for them yet. In this case, it is necessary to generate alternative idle orders corresponding to the idle orders to be adjusted. Figure 3 This is a flowchart illustrating the method provided in this application for generating alternative idle orders based on idle orders and locking idle orders. For example... Figure 3 As shown, generating alternative idle orders based on idle orders and locked idle orders includes the following steps: Step S301: Plot idle orders and locked idle orders on the same two-dimensional coordinate system to obtain the distribution information of locked idle orders in idle orders.
[0046] Step S302: Obtain the sparse region in the distribution information and the coefficient charging station in the sparse region, and determine the unselected orders in the idle orders sent by the sparse charging station as the alternative idle orders corresponding to the adjusted idle orders.
[0047] Idle orders comprise several sub-orders, each corresponding to a location. Locked idle orders also comprise several sub-orders, each corresponding to a location. By using these locations, idle orders and locked idle orders can be plotted on the same two-dimensional coordinate system to obtain the distribution information of locked idle orders within idle orders. Specifically, this distribution information refers to the location distribution map presented in the two-dimensional coordinate system.
[0048] Subsequently, the distribution information is divided into several regions based on the area where each charging station is located. Then, the proportion of sub-orders within idle orders in each region is calculated and compared with a preset proportion. If the proportion is greater than the preset proportion, the region is considered a dense region; if it is not greater, the region is considered a sparse region. Charging stations located in these sparse regions are then designated as sparse charging stations. These sparse charging stations may have unselected charging piles (i.e., some are idle). To improve the rationality of charging station allocation, unselected orders from sparse charging stations are identified as potential alternative idle orders for adjustment. Specifically, all sparse charging stations can be considered simultaneously to ensure that unselected orders from each sparse charging station have an equal probability of being reselected.
[0049] Subsequently, the management system sends the confirmed alternative idle orders to the new energy vehicles corresponding to the adjusted idle orders, i.e., the adjusted new energy vehicles. This allows these adjusted new energy vehicles to understand that the charging station they previously selected is unable to charge them and they need to wait, and also allows these new energy vehicles to determine whether to accept the adjustment of the charging station they previously selected.
[0050] Step S400: Receive confirmation information sent by the new energy vehicle adjustment, and generate a confirmed idle order corresponding to the new energy vehicle adjustment based on the confirmation information.
[0051] This includes receiving confirmation messages from new energy vehicles after receiving idle order requests. These confirmation messages include sub-messages from each new energy vehicle request, each specifying either a self-selected idle order or vehicle location from the available idle orders. After receiving the confirmation messages, the management terminal also needs to determine the final charging station for each new energy vehicle based on these messages. Figure 4 This is a flowchart illustrating the method for generating and adjusting confirmed idle orders corresponding to new energy vehicles based on confirmation information, as provided in this application. Figure 4 As shown, generating and adjusting confirmed idle orders for new energy vehicles based on confirmation information includes the following steps: Step S401: Determine whether the sub-information contains any self-selected idle orders. If so, determine any one of the self-selected idle orders as the confirmed idle order corresponding to the new energy vehicle.
[0052] Step S402: If not, confirm the order closest to the vehicle location among the candidate idle orders as the confirmed idle order corresponding to the adjusted new energy vehicle.
[0053] Taking the adjustment of a new energy vehicle as an example, by examining the information contained in the corresponding confirmation sub-information for that new energy vehicle, it can be determined whether the confirmation sub-information includes any self-selected idle orders. Specifically, the confirmation sub-information will only contain one of the following: self-selected idle orders or vehicle location. If the new energy vehicle being adjusted does not accept any of the sent self-selected idle orders, it will send a confirmation sub-information containing the vehicle location to the management terminal. If the new energy vehicle being adjusted accepts any of the sent self-selected idle orders, it will send a confirmation sub-information containing self-selected idle orders to the management terminal. When configuring a new energy vehicle, the management terminal will only send the same charging station to one new energy vehicle being adjusted.
[0054] The inclusion of self-selected idle orders in the confirmed sub-information indicates that the new energy vehicle corresponding to this sub-information is receiving charging at a charging station sent by the management terminal. Any one of the self-selected idle orders can be designated as the confirmed idle order for the new energy vehicle. This approach balances the rationality of charging station allocation with respect for the choices made by the new energy vehicle.
[0055] If the confirmed sub-information includes vehicle location, it indicates that the new energy vehicle corresponding to this sub-information will not accept charging at the charging stations sent to it by the management terminal. The vehicle's location is then sent to the management terminal. At this point, the management terminal selects the order closest to the vehicle's location from the pool of available idle orders as the confirmed idle order for the adjusted new energy vehicle. This allows the management terminal to select a relatively suitable charging station for the new energy vehicle based on its location, while ensuring the rationality of charging station allocation.
[0056] Finally, the confirmed idle orders are sent to the new energy vehicles so that they know where they need to go for charging.
[0057] In step S500, the locked idle orders and confirmed orders are sent to the corresponding charging stations to adjust the idle orders of the charging stations.
[0058] The aforementioned locked idle orders and confirmed orders are orders that new energy vehicles need to go to for charging. The management terminal sends instructions to the corresponding charging stations based on these locked and confirmed orders, so that these charging stations know how many new energy vehicles they need to receive charging services for, and adjust the idle orders sent to the management terminal accordingly. This automatically and more rationally allocates charging stations, reducing the situation where some charging stations are congested while others are idle. Furthermore, making charging station information transparent allows users to quickly find available charging stations, reducing charging wait times.
[0059] Preferably, the management terminal also obtains the electricity consumption of each charging station, substitutes the electricity consumption into the preset electricity price relationship to obtain the charging unit price corresponding to the charging station, and sends the charging unit price to the new energy vehicle.
[0060] Specifically, each charging station records its real-time electricity consumption. Through a communication connection between the management terminal and the charging stations, the management terminal obtains the electricity consumption of each charging station. Then, it substitutes the electricity consumption of each charging station into a preset electricity price relationship to obtain the corresponding charging unit price for each charging station, and sends the charging unit price to each new energy vehicle. The aforementioned electricity consumption refers to real-time electricity consumption, and the preset electricity price relationship is obtained by fitting historical prices and charging volume. Higher electricity consumption indicates that more new energy vehicles are charging at that charging station, and the price will increase accordingly. This reduces the occurrence of new energy vehicles concentrating at a single charging station, indirectly improving the rationality of charging station allocation.
[0061] Preferably, the management terminal also obtains the cumulative working time and single working time of each charging pile in each charging station, and substitutes the cumulative working time and single working time into a preset maintenance model to obtain the maintenance information of that charging pile. The preset maintenance model is trained based on historical single continuous working time, cumulative continuous working time, and fault information of charging piles. This allows for the prediction of charging pile faults, enabling proactive measures to be taken to reduce the impact of faults on charging efficiency and operation and maintenance costs.
[0062] Preferably, the management terminal also obtains the working percentage of each charging pile in each charging station, determines whether the working percentage exceeds the preset percentage, and if it does, sends a charging power adjustment signal to the new energy vehicle corresponding to each working charging pile; receives the adjustment information sent by the new energy vehicle, and determines the actual charging power of the new energy vehicle based on the adjustment information.
[0063] Specifically, the management system calculates the working percentage by dividing the number of active charging piles at each charging station by the total number of charging piles. This working percentage is then compared to a preset percentage. The preset percentage indicates the busyness level of the charging piles at that station, and its specific value is determined based on actual conditions. If the working percentage exceeds the preset percentage, it indicates that the charging piles at that station are busy. In this case, a power adjustment signal can be sent to each active charging pile at that station to increase the charging power for those new energy vehicles. The system then receives feedback from these new energy vehicles based on the received power adjustment signal to determine whether they accept the increased charging power. The adjustment information includes either acceptance or rejection. If the adjustment information indicates acceptance, the charging power is increased by one level from the existing power level to become the actual charging power for that new energy vehicle. If the adjustment information indicates rejection, the existing charging power continues to be used as the actual charging power for that new energy vehicle. This allows for dynamic adjustment of charging strategies based on actual needs and the status of charging stations, reducing the waste of charging pile resources and improving the user experience.
[0064] Figure 5 This is a connection diagram of a new energy charging station management system provided in this application. Figure 5 As shown, a new energy charging station management system includes: a charging station broadcast module, a charging station initial management module, a charging station re-management module, and a charging station adjustment module.
[0065] The system comprises several modules: a charging station broadcast module, a charging station management module, and a charging station adjustment module. The former receives idle orders from each charging station and broadcasts them to the new energy vehicles. The latter receives selected idle orders and feedback from new energy vehicles, retrieves information about associated charging stations, and determines which idle orders need to be locked and which need adjustment based on this information. The latter generates alternative idle orders for the adjusted orders based on the existing idle orders and locked orders, and sends these alternative orders to the corresponding new energy vehicles. It also receives confirmation from the adjusted new energy vehicles and generates confirmed idle orders based on this confirmation. Finally, the former sends locked and confirmed idle orders to the corresponding charging stations to adjust their idle order lists.
[0066] The other functions performed by the above-mentioned charging station broadcast module, charging station initial management module, charging station re-management module and charging station adjustment module, as well as the technical details of each function, are the same or similar to the corresponding features in the new energy charging station management method described above, so they will not be repeated here.
[0067] This application also provides a computer storage medium storing a computer program that, when run on a computer, enables the computer to execute the steps in the aforementioned new energy charging station management method.
[0068] It should be understood that although the steps in the flowcharts in the accompanying figures are shown sequentially as indicated by the arrows, these steps are not necessarily performed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order requirement for the execution of these steps, and they can be performed in other orders.
[0069] The above description is only a partial embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
