Abstract

A method and display for displaying the operating range of an electric drive vehicle and a display for carrying out same are provided. The battery energy in a vehicle is detected, and a maximum operating range of the vehicle is determined therefrom. At least one battery service station is selected as destination point for determining the maximum operating range. Based on a starting point, a reachability threshold is determined. If exceeded, the vehicle will be unable to reach the destination point with the current battery energy available, wherein said reachability threshold is displayed as an operating range in a map illustration. During the determination of the reachability threshold, the current location is used as the starting point and the current battery energy of the vehicle is used, both of which are updated at pre-defined intervals while the vehicle is moving.
