Embodiment 1

[0047] In the embodiment of the present invention, a reasonable charging station selection and driving scheme is obtained through mutual feedback information between electric vehicle users and the charging operation center. The embodiment of the present invention makes full use of the correlation between the straight-line distance between two locations in the road network and the driving distance, based on the straight-line distance between the charging request point and the charging station, combined with the deviation angle coefficient between the charging station and the destination location, through Calculate and determine the charging cost value of each charging station. At the same time, in order to further ensure the accessibility between the charging request point and the selected charging station and ensure the accuracy of the results, and provide the user with charging driving route information, the embodiment of the present invention adds a route length inspection pr...

Embodiment 2

[0089] This embodiment provides a charging route induction method for an electric vehicle considering the remaining battery capacity. Usually, when the user generates a charging request, the remaining capacity of the car is relatively small. At this time, the user can send a charging request to the charging operation center. The charging operation center saves the location information of all charging stations in the area it manages. SOC value and travel destination. see figure 1 After receiving the charging request from the user, the charging operation center executes the method provided by the present invention, and sends the result of the charging route guidance method to the user.

[0090] The specific execution process of the method can be found in Figure 4 . The method first determines the maximum distance that can be driven by the current remaining power of the electric vehicle based on the current remaining power of the electric vehicle, and then starts to search fo...

Abstract

The embodiment of the invention provides an induction method of a charging circuit of an electric automobile by considering residual electricity quantity of a cell. The method comprises following steps that a charging operation center records a charging request point position coordinate of an electric automobile user after receiving a charging request of the electric automobile user, the current automobile residual electricity quantity and the outgoing destination position coordinate; the charging operation center calculates the drivable biggest distance of the automobile according to the current automobile residual electricity quantity, and acquiring a reachable charging station set according to the drivable biggest distance; charging fee values corresponding to the charging stations in the reachable charging station set are calculated according to a set algorithm and charging station distribution schemes of electrical automobile users are determined according to the charging fee values; and the charging operation center sends the schemes to the electric automobile users and the users drive to corresponding charging stations to finish the charging according to the charging station distribution schemes. According to the invention, by considering the whole outgoing link characteristics of the users, the method is advantaged by comprehensive consideration factors, simple structure and small calculation quantity.

Description

technical field [0001] The invention relates to the field of electric vehicle traffic guidance, in particular to a charging route guidance method for electric vehicles considering the remaining battery power. Background technique [0002] As traditional fuel vehicles cause more and more energy and environmental problems, people will invest the main development direction of the future automotive industry on electric vehicles with high energy efficiency and good environmental protection effects. While electric vehicles have the advantages of saving resources and zero exhaust emissions, they also have the disadvantage of short driving range, and users often have mileage anxiety during travel. When users find that the remaining power of the car may not be able to reach the destination, they will have a strong desire to charge; however, due to the relatively lagging construction of charging facilities for electric vehicles, it is always difficult for electric vehicle users to fin...
