1. A method for charging an electric vehicle comprising:
charging a traction battery of the electric vehicle connected to a stationary charging device by the stationary charging device; and, before the electric vehicle is disconnected from the stationary charging device,
operating a heating device of the electric vehicle with electrical energy provided by the stationary charging device;
heating the traction battery and a component of a drive train of the electric vehicle by the heating device to a predetermined temperature which is optimal in terms of an efficiency factor of the electric vehicle, wherein a first temperature sensor is configured to sense a temperature of the traction battery and a second temperature sensor is configured to sense a temperature of the component of the drive train;
calculating, with a control module of the electric vehicle, a preheating time ending at a predetermined departure time set from a programmed calendar, wherein the preheating time is calculated based upon temperatures recorded by both the first temperature sensor and the second temperature sensor; and
operating the heating device during the calculated preheating time immediately before the predetermined departure time, wherein the charging is finished before the predetermined departure time.
