The invention provides a shortest path Thiessen polygon-based electric vehicle charging station searching method. The method comprises the following steps: S1, acquiring the specific geographical locations of all available charging stations within an area, and establishing a Delaunay triangular network by taking the positions of all the charging station as discrete points; S2, obtaining a Thiessen polygon formed by the discrete points according to circumscribed circles of all triangles in the Delaunay triangular network; S3, using a car networking system to search the position of the most convenient charging station closest to an electric vehicle according to the Thiessen polygon and the information of the discrete points, and feeding back same to the electric vehicle, wherein the car networking system can collect the information of vehicles and charging stations in real time. By performing Thiessen polygon subdivision analysis on charging station site power supply service areas within the area, the method pushes the charging station, which is closest to the vehicle, to the vehicle in demand, thus facilitating the vehicle to be charged in time.
