Abstract: Method for displaying the actual range of an electric vehicle from a starting point shown on a map, in the course of which based on the given parameters of the vehicle it is determined that on a horizontal surface for a covering a certain distance how much electric consumption is necessary, how much the maximum consumption can be, it is also determined that with respect to roads with different steepness to what extent (correction factors) the actual consumption varies from the consumption on a horizontal surface, then the map data is input into the map database with respect to a hypothetical range from the starting point and from the starting point the set of discrete peak points on the map is indicated, where the steepness of the surface between two neighboring peak points is considered steady, then the costs of the various available routes are determined from the starting point with Dijkstra algorithm and using a successive iteration, where the cost between two peak points mean the value modified by the cor
