Embodiment

[0045] In this embodiment, the electric vehicles are divided into four categories according to the current state of the electric vehicles.

[0046] Consider the attributes of potential charging stations in the route, including slow charging stations and fast charging stations, and distinguish them by the method of charging efficiency difference.

[0047] According to the classification of electric vehicles, the optimal path search methods for four types of electric vehicles are given respectively.

[0048] The best route search idea for electric vehicle auxiliary route is:

[0049] The electric vehicle auxiliary route refers to a feasible electric vehicle driving route scheme, on which the electric vehicle can ensure that the electric vehicle can be charged in time before the power is exhausted so as to reach the destination smoothly. Therefore, the main idea of ​​the present invention is to first search for potential electric vehicle charging stations that can be charged, an...

Embodiment 2

[0124] It is basically the same as Embodiment 1, except that, in step 4, when the electric vehicle reaches the destination, the remaining power of the electric vehicle is:

[0125] BL A =BL F -D(SCS j , Des) / EM;

[0126] If the total driving distance is selected for sorting, calculate the driving route with the shortest total driving distance, select all the routes with the shortest difference from the total driving distance within the threshold, and use the route with the highest remaining power of the electric vehicle as the automatic selection route;

[0127] If the total travel time is selected for sorting, the route with the shortest total travel time is calculated, and all routes whose difference from the total travel distance time is within the threshold are selected, and the route with the highest remaining battery capacity of the electric vehicle is automatically selected.

Embodiment 3

[0129] It is basically the same as Embodiment 2, except that in step 4, if the user selects the most economical travel route in step 4, the preset weight value is added to the total travel distance and the total travel time respectively, and the total The driving distance is multiplied by the weight value and the total driving time is multiplied by the weight value and then added to obtain the total value for sorting, and the route with the highest total value is used as the automatically selected route.

Abstract

The invention relates to an electric car path optimal seeking method considering the range and charging station position. The method overcomes defects in the prior art. According to the technical scheme, a seek idea for clearing the optimal path through an electric car auxiliary line is provided; paths, mileages and time consumption functions by adopting starting and final positions as variables are built; according to the current status of electric cars, the electric cars are divided into four types; the potential charging station attributes in the paths are considered, a slow charging station and a rapid charging station are included and distinguished through a charging efficiency variance method, and the optimal path for four types of electric cars can be given according to the types of the electric cars through the seeking method.

Description

technical field [0001] The invention relates to an electric vehicle path optimization method, in particular to an electric vehicle path optimization method considering the voyage and the location of a charging station. Background technique [0002] With the intensification of the energy and environmental crisis, new energy technologies have received extensive development and attention. In recent years, electric vehicles, as the pioneer of the new energy revolution in the field of transportation, have been widely promoted and applied. The primary problem restricting the development of electric vehicles is battery capacity and life. With the continuous improvement of battery technology, the battery life and service life of electric vehicles have been greatly improved. In terms of battery life, the current most advanced electric vehicles have reached about several hundred kilometers, but there is still a gap compared with conventional vehicles. [0003] The emergence of elect...
