Assignee: AUDI AG
Field: Transport (Mechanical engineering)
Classification: CPC B  F  Y | IPC B  F  H

Claim 6:
7. An electric vehicle comprising:
a traction battery;
a heating device configured to:
charge the traction battery from a stationary charging device when the electric vehicle is connected to the stationary charging device and
operate with electrical energy provided by the stationary charging device before the electric vehicle is disconnected from the stationary charging device, wherein the traction battery and a component of a drive train of the electric vehicle is heated by the heating device to a predetermined temperature;

a first temperature sensor is configured to sense a temperature of the traction battery;
a second temperature sensor is configured to sense a temperature of the component of the drive train, wherein the predetermined temperature is optimal in terms of an efficiency factor of the electric vehicle; and
a control module configured to:
provide a predetermined charging mode,
calculate 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
control operation of the heating device during the calculated preheating time immediately before the predetermined departure time, wherein the charging is finished before the predetermined departure time.
