Embodiment Construction
[0049] Such as figure 1 As shown, in this embodiment, the comprehensive optimization method for the electric vehicle travel route considering the charging time includes:
[0050] 1) Calculate the maximum travel distance MS according to the remaining battery capacity of the travel electric vehicle NV1 ;
[0051] 2) According to the maximum driving distance MS NV1 Determine the covered charging stations to get the set of reachable charging stations;
[0052] 3) Initialize the value of the loop variable i to 1, traverse and select a current charging station i from the set of reachable charging stations;
[0053] 4) Construct the road network Neti from the initial position of the travel electric vehicle to each destination via the current charging station i;
[0054] 5) Judging the number of vehicles DVN waiting to be charged in the current charging station i i Less than the allowable number of queuing vehicles DVN of electric vehicles to be charged in the current charging st...

The invention discloses an electric vehicle travel route comprehensive optimization method considering charging time, and the method comprises the steps: determining a covered charging station according to the maximum travel distance MSNV1 of a travel electric vehicle to acquire a reachable charging station set, and generating a road network; initializing a cyclic variable i, and traversing and selecting a current charging station i from the reachable charging station set; judging whether the queuing vehicle number of to-be-charged electric vehicles in the current charging station i is smallerthan a threshold value or not, and if so, generating multiple candidate travel route schemes between the initial position of the travel electric vehicle and the last destination; and adding 1 to thecyclic variable i, repeating iteration until traversal of the reachable charging station set is completed, and finally selecting a candidate travel route scheme with the shortest required time to output. According to the invention, the electric vehicles can support longer-distance travel route scheduling, a more accurate time management scheme is provided, and the time utilization efficiency of the electric vehicle can be effectively improved.
Description
technical field [0001] The invention relates to an electric vehicle travel route scheduling technology, in particular to a comprehensive optimization method for an electric vehicle travel route considering charging time. Background technique [0002] Electric vehicle (electric vehicle) leasing is a new type of leasing business model. In this leasing business model, due to the limited battery life of electric vehicles, the destination needs to be considered in the scheduling of electric vehicle travel routes, and it is also necessary to consider whether the current power of electric vehicles can support reaching the destination. At present, for the scheduling of electric vehicle travel routes, it is still generally not considered the scheduling of charging status, which limits the distance of electric vehicle travel routes. Therefore, how to realize the electric vehicle travel route scheduling considering the charging time has become a key technical problem to be solved urge...
