Abstract

The invention discloses an intelligent charging navigation method for an electric vehicle. The intelligent charging navigation method comprises the following steps that (1) based on a wireless networkand GPRS, a large quantity of vehicle information, road condition information and charging station information are unloaded to a control center, and excavating extraction of characteristic data is conducted; (2) extracted information data based on an objective function are analyzed and calculated; (3) minimized values of the user travel total time cost and total distance cost form the objective function, the time and capacity serve as constraint conditions, and thus an optimal charging path including the three aspects of charging resources, road traffic nets and the road condition informationis set out based on a Dijkstra algorithm; and (4) the optimal charging path is unloaded to an EV vehicle-mounted terminal and a user cell phone APP through the wireless communication network. The total time cost and the total distance cost of the electric vehicle from a charging station to a final destination can be reduced effectively, and meanwhile user travel convenience is improved.

Description

technical field [0001] The invention relates to an electric vehicle intelligent charging navigation method, which belongs to the technical field of electric vehicle charging. Background technique [0002] Electric vehicles are my country's strategic emerging industries, which play an important role in improving my country's energy security, coping with climate change, and improving environmental protection. my country attaches great importance to the development of the electric vehicle industry. General Secretary Xi Jinping pointed out that "the development of new energy vehicles is the only way to become a powerful automobile country". Our country has formulated many important industrial policies, which provide an important guarantee for promoting the development of electric vehicles. Electric vehicle charging facilities are an important part of the smart grid and the basic guarantee for the development of the electric vehicle industry, which has developed rapidly in recen...
