Dynamic charging path planning method for electric vehicle

The invention provides a dynamic charging path planning method for an electric vehicle. The method includes the following steps of judging whether the electric vehicle needs to be charged, selecting a candidate charging station and determining a charging path of the electric vehicle. According to the dynamic charging path planning method for the electric vehicle, dynamic traffic information publishing and navigation are carried out by means of the internet, an optimal path planning algorithm is researched, a GIS technique is used, and then the optimal charging path is provided. Imbalance of charging resources is avoided, traveling efficiency of the vehicle is improved, and negative influences of the behavior that the electric vehicle looks for the charging station on a traffic system are reduced to the largest extent.
