[0047] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] The present invention provides a multi-charging pile linkage charging method, which is used to solve the problem of charging pile resource shortage in the prior art.

[0049] Embodiment 1:

[0050] See also Figure 1 , Figure 1 The present invention provides a first flow chart of a method for linked charging of multiple charging piles according to an embodiment of the present invention.

[0051] S100, obtaining the current user location, the destination location, and the current user's remaining battery mileage, searching for a first navigation path from the current user location to the destination location, and identifying charging piles along the way based on the first navigation path when the mileage of the first navigation path is greater than the current user's remaining battery mileage; obtaining the first location of the charging piles along the way and the fragmented time charging mileage; based on the first location of the charging piles along the way and the current user location, identifying the charging piles along the way that can be reached by the current user's remaining battery mileage, and obtaining the first charging pile and the corresponding first journey time;

[0052] It should be noted that the destination set in this embodiment is generally a charging station that can be charged for a long time, or a private fixed charging point at the residence. The power of the new energy vehicle driven by the user is not enough to support the user to drive from the current location to the destination. The purpose of this solution is to integrate the fragmented free time of multiple charging piles along the first navigation path so that the user can drive to the destination.

[0053] When the user is navigating to the destination, the vehicle's position can be detected in real time as the current user position, and the navigation end point can be used as the destination. The current remaining power or mileage of the vehicle can be obtained in real time based on the vehicle information. The mileage of the first navigation path from the current user position to the destination obtained based on the navigation is compared with the user's remaining power mileage. When the mileage of the first navigation path is greater than the current user's remaining power mileage, it means that the user's vehicle's power is insufficient to support the user's driving from the current position to the destination, and it is necessary to integrate the fragmented charging mileage available at the charging piles along the way so that the user can reach the destination for charging;

[0054] In this embodiment, it is assumed that the charging resources of the charging piles along the first navigation path are tight, the charging piles are not available for a long period of time, they are occupied and have been scheduled for charging, and there will be a certain time difference between the end of the current charging user at the charging pile and the start time of the charging scheduled by the next user, and this time difference is the fragmented charging time; the charging piles along the way are identified according to the distance from the charging piles around the first navigation path to the first navigation path, and a circle is drawn on the map with the charging pile as the center and the preset proportional length of the first navigation path as the radius. If the circle passes through the first navigation path, the corresponding charging pile is identified as the charging pile along the way, and the preset proportional length can be 5%-10%; after determining that the user's current power cannot reach the destination, the distance between the charging piles along the first navigation path and the current user's location is identified, and the first charging pile that can be reached must be found before subsequent joint charging can be realized, and all charging piles that can be reached by the current power are identified to obtain the first charging pile, and the first distance time is the distance time required for the user's current location to each charging pile.

[0055] S200, determine whether the sum of the fragmented time charging mileage of the first charging pile and the current user's remaining power mileage is greater than the sum of the distance from the current user's position to the first charging pile and the distance from the first charging pile to the destination position. If not, based on the nearest position of the charging piles along the way on the first navigation path, sort them according to the direction of the first navigation path, take each first charging pile as the starting point of the charging pile linkage, arrange and combine the charging piles along the way sorted after the first charging pile, and combine them into multiple charging pile linkage schemes; obtain the fragmented time charging mileage of the charging piles in each linkage scheme and the distance between the charging piles, substitute them into the linkage charging scheme judgment model, and identify the linkage charging scheme that meets the model. The linkage charging scheme judgment model is specifically:

[0056]

[0057] Among them, R 0 is the current user's remaining battery mileage, r n+1 is the distance between the nth charging station and the n+1th charging station, r 1 is the distance from the user's current location to the first charging station, r a+1 is the distance from the ath charging station to the destination, R n Charging mileage for the nth charging station during the fragmented time;

[0058] It should be noted that after all the first charging piles are identified in the above steps, it is necessary to determine again whether the destination can be reached after charging at the fragmented time of the first charging pile. If not, multiple charging piles along the way need to be charged in conjunction to enable the vehicle to reach the destination; the intersection of the circle drawn on the map of the charging piles along the way and the first navigation path is the judgment point of the charging piles along the way, and the judgment points of the charging piles along the way are sorted according to the direction from the current position to the destination position on the first navigation path. The closer the judgment point is to the current position on the first navigation path, the higher the ranking; the charging piles along the way that are identified as the judgment points corresponding to the first charging piles are arranged and combined. For example, after the first charging pile is sorted, there are still three charging piles along the way, which are charging pile a, charging pile b and charging pile c in order, then a calculation method can be formed. A linkage charging scheme, in which the order between charging piles is not considered, this embodiment goes to the charging piles along the way to charge in the order of the judgment points, avoiding repeated paths such as backtracking, which affects the path efficiency of joint charging;

[0059] The fragmented time charging mileage of the charging piles and the distance between the charging piles in each linkage scheme are substituted into the judgment model. The judgment model is used to judge whether the power of the user vehicle can support its travel to the next charging pile along the way after charging at a charging pile along the way. For example, when there are two charging piles along the way after the first charging pile, a total of three charging piles constitute a linkage charging scheme, it is necessary to use the judgment model to determine whether the mileage increased by the corresponding user vehicle at the second charging pile when charging at fragmented time when n=2 and n=3 can support the arrival at the third charging pile, and whether the user vehicle can support reaching the destination after charging at the third charging pile at fragmented time.

[0060] S300, obtaining the travel time and charging time in each linkage charging scheme that meets the model, substituting them into the time calculation model, identifying the linkage charging scheme with the least total time consumption, and sending fragmented time charging reservation information to the charging pile. The time calculation model is specifically:

[0061]

[0062] Among them, T min The minimum total time of the linkage charging scheme, t n is the time taken for the nth segment, T n The fragment charging time for the nth charging station.

[0063] It should be noted that after the aforementioned step S200, multiple linkage charging schemes may be obtained that can meet the needs of the user's vehicle arriving at the destination, and the user will inevitably choose the best linkage charging scheme from them, and the time consumption of the scheme is the key factor in selecting the scheme; the time consumption in the linkage charging scheme depends on the sum of the time consumed by the user in driving between the charging piles and the time consumed in charging at the charging piles. By calculating the total time consumed by each charging linkage scheme and finding the linkage charging scheme with the least time consumption, an instruction for fragmented charging time reservation can be sent to the charging piles along the way passed by the scheme to avoid other users occupying or reserving charging, thereby realizing the linkage charging of multiple charging piles; the fragmented charging time reservation of the charging piles can be made according to the time when the user expects to arrive at the charging pile.

[0064] In this embodiment, the charging pile information on the current navigation path is analyzed, and the charging amount of the charging piles during fragmented time and the path between the charging piles are used to determine whether each charging pile can support the user's vehicle to reach the next charging pile. After calculating the linked charging plan that can meet the user's needs to reach the destination during fragmented time, the plan with the shortest total time is selected. This allows the user to reuse the fragmented time of multiple charging piles when the battery is low and the charging pile resources are tight, and to charge in a linked manner, thereby increasing the vehicle's endurance, enabling the user to reach the destination, improving the charging efficiency of the charging piles, and reducing the user's anxiety about using the car.

[0065] The above is a detailed description of the first embodiment of a multi-charging pile linkage charging method provided by the present application. The following is a detailed description of the second embodiment of a multi-charging pile linkage charging method provided by the present application.

[0066] In this embodiment, a multi-charging pile linkage charging method is further provided. Figure 2 In the aforementioned step S200, after obtaining the fragmented time charging mileage of the charging piles and the distance between the charging piles in each linkage scheme, steps S201-S202 are also included, specifically:

[0067] S201, obtaining the starting time point and current time point of the fragmented time of each charging pile, substituting the current time point, the starting time point of the fragmented time of each charging pile, the journey time and the fragmented charging time into the error judgment model, and identifying the fragmented time charging pile with errors. The error judgment model is specifically:

[0068]

[0069] Among them, tp 0 is the current time point, tp n is the starting time of the nth charging pile fragmentation time, t 1 is the travel time from the current user location to the first charging station, t nis the travel time from the n-1th charging pile to the nth charging pile, T n-1 is the fragmentation time of the n-1th charging pile;

[0070] It should be noted that after adding the travel time between the charging piles and the fragment time of the charging piles to the current time point, the result is the time point when the user arrives at the next charging pile, that is, the current time point plus the travel time from the current user's location to the first charging pile and then to the second charging pile, plus the charging fragment time of the first charging pile, to obtain the time point when the user's vehicle arrives at the second charging pile. After subtracting the starting time point of the fragment time of the second charging pile, if it is positive, it means that the user cannot make full use of the fragment time when arriving at the second charging pile, and some of the fragment time is consumed on the journey before the user arrives at the charging pile. Therefore, there is an error in the fragment time of the charging pile, and the actual amount of electricity that can be charged for the user's vehicle is less, and correction is needed.

[0071] S202, substituting the charging pile data with errors into the correction model to obtain the corrected fragmented time charging mileage and charging time, and replacing the corresponding data. The correction model is specifically:

[0072]

[0073] in, is the fragmented time charging mileage correction value of the nth charging pile, is the fragment charging time correction value of the nth charging pile, and θ is the conversion ratio between the charging time and charging mileage of the charging pile;

[0074] It should be noted that after determining that the fragmentation time has begun when the user arrives at the charging pile, the user's actual charging mileage and charging time need to be corrected. After subtracting the error value spent on the road map from the original charging time, the actual charging time of the nth charging pile for the user's vehicle can be calculated. The charging time is proportional to the charging mileage. According to the conversion ratio, the actual endurance charging mileage charged to the user's vehicle can be obtained. After obtaining the two correction values, the corresponding data are replaced, that is, R n Replace with corrected value T n Replace with corrected value Get more accurate data and improve the accuracy of subsequent calculations of the linkage charging solution.

[0075] Furthermore, after the aforementioned step S201, the method further includes: if the waiting judgment model is satisfied, calculating the time difference between the start time of the charging pile fragmentation time and the time point when the user arrives at the charging pile, obtaining the waiting time, and adding the waiting time to the time calculation model;

[0076] The waiting judgment model is:

[0077]

[0078] It should be noted that satisfying the waiting judgment model means that when the user arrives at the charging pile, there are still other users using the charging pile, and the fragmented time has not yet arrived. When calculating the total time consumed by the linkage charging solution in the aforementioned step S300, the waiting time for charging needs to be included; the calculation model for the waiting time is:

[0079]

[0080] Among them, T wn is the waiting time for the nth charging pile, Add it to the calculation of the total time consumption of the linkage charging scheme.

[0081] The above is a detailed description of a multi-charging pile linkage charging method provided in the first aspect of the present application. The following is a detailed description of an embodiment of a multi-charging pile linkage charging system provided in the second aspect of the present application.

The error judgment model is specifically as follows:

[0092]

[0093] Among them, tp 0 is the current time point, tp n is the starting time of the nth charging pile fragmentation time, t 1 is the travel time from the current user location to the first charging station, t n is the travel time from the n-1th charging pile to the nth charging pile, T n-1 is the fragmentation time of the n-1th charging pile;

[0094] Substitute the charging pile data with errors into the correction model to obtain the corrected fragmented time charging mileage and charging time, and replace the corresponding data. The correction model is specifically:
