Abstract

A method is described for operating a motor vehicle which is driven with the aid of an electric machine, the electric machine being supplied with electrical energy from an energy store which is charged by an external energy source. To ensure that the driver receives the information concerning readiness for continued travel of the vehicle at the point in time when sufficient energy is present in the energy store in order to reliably reach the intended destination or to cover a predetermined route, the motor vehicle is notified of a destination and/or a route, and the motor vehicle is connected to the external energy source for charging the energy store, the motor vehicle outputting information as to when the energy store has been charged with sufficient energy to reach the destination or to cover the route, and the driver stopping at a next charging station in particular after having reached the destination or having covered the route.
