1. A method for controlling a state of charge of a battery of a vehicle in order to ensure startability of the vehicle, the method comprising the acts of:

  • ascertaining, via a programmed control unit, a predicted battery-temperature at a future location of the vehicle at a future time, based on vehicle navigation system data;

    determining, via the programmed control unit, a lower limit for the state of charge, the lower limit being the state of charge necessary to start the vehicle at the future time based on the predicted battery-temperature at the future location at the future time; and

    controlling, via the programmed control unit, the state of charge, prior to the vehicle arriving at the future location, such that the state of charge at least does not fall below the lower limit.
