Induction method of charging circuit of electric automobile by considering residual electricity quantity of cell

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...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of the electric vehicle charging route induction method in the above-mentioned prior art are: firstly, the travel needs of electric vehicle users are not fully considered, and the goal considered when determining the optimal charging station is relatively single, and usually only the nearest charging station is used as the target. The goal is to select a charging station for the user, without considering the entire travel chain of the user; secondly, the proposed method is more complicated, with a large amount of calculation, and it is difficult to obtain a charging station selection plan in a short time in the actual application process Users provide timely feedback results
