Abstract
A person is to be assisted in planning a journey with an electric vehicle. Information relating to an overall region with destinations within reach of the electric vehicle are outputted. For this purpose, a starting region is determined, from which a boundary can be reached with the electric vehicle from a current vehicle location and based on a current state of charge of the energy storage device without recharging. Locations of charging stations are then determined in the starting region. For each charging station, the boundary of a region is determined that can be reached indirectly from the respective charging station without further recharging, based on a state of charge that changed when the electric vehicle was recharged. The overall region is composed of the starting region and regions that can be reached indirectly.
