A method for assisting a person with planning a journey with an electric vehicle, comprising:
- acquiring a current vehicle location at which the electric vehicle is located;
- acquiring a current state of charge of an energy storage device of the electric vehicle, which stores energy for a drive motor of the electric vehicle;
- determining a starting region having a first boundary that is within reach of the electric vehicle from the current vehicle location and based on the current state of charge without recharging energy;
- determining locations of charging stations for the electric vehicle in the starting region;
- for each of the charging stations, determining an indirectly reachable region having a second boundary that is within reach from a respective charging station and based on a state of charge that was changed at the respective charging station in a predetermined manner, without additional recharging;
- determining, in a recursive manner, for an additional charging station in the indirectly reachable region an additional indirectly reachable region, whose boundary is within reach from this additional charging station and based on a state of charge that was changed at the additional charging station in a predetermined manner, without additional recharging,
- outputting information for an overall region formed by the starting region and the indirectly reachable regions, wherein for outputting the information a road map is displayed, on which the overall region is indicated,
- marking zones in the overall region indicated on the road map, with markings of the zones indicating:
- a) a minimum number of charging stations required for recharging energy in order to reach the respective zone, or
- b) at least one of the charging stations or the additional charging station, via which a respective zone can be reached, wherein when a zone can be reached via a plurality of the charging stations, using the charging station
- where energy needs to be recharged last to reach the respective zone, or
- via which the shortest path leads from the current vehicle location to the respective zone, or
- via which the respective zone can be reached in the least amount of time, or
- via which the respective zone can be reached with lowest energy consumption.
