Abstract

In a method for determining the range of a motor vehicle, the temperature of at least one predetermined component of the motor vehicle and/or another parameter which detects the physical or chemical state of the component, and/or a measured outer temperature or outer temperature known from wirelessly transmitted weather data or other environmental parameter at the location of the motor vehicle and/or on a planned driving course are taken into account, and the amount of energy to be consumed in dependence of the at least one parameter, by at least one power consumer for establishing and/or maintaining the operability of the motor vehicle is taken into account for determining the range.

Claims

1-7. -7. (canceled)

8. A method for determining a range of a motor vehicle, comprising;

determining as a function of a temperature of an electrochemical storage device for operating a drive of the motor vehicle and of an outside temperature at a location of the motor vehicle, an amount of energy required by a device of the motor vehicle for preheating the electrochemical energy storage device for establishing an operability of the motor vehicle, wherein the outside temperature is measured or is obtained from wirelessly transmitted weather data; and

determining the range of the motor vehicle as a function of the amount of energy required by the device for preheating the electrochemical storage device.

9. The method of claim 8, further comprising measuring a temperature of at least one further component of the motor vehicle, wherein the range of the motor vehicle is determined further as a function of the temperature of the at least one further component of the motor vehicle.

10. The method of claim 8, wherein said method is performed at a start of a drive of the motor vehicle, said range being determined in the motor vehicle, said method further comprising wirelessly transmitting the range to a device outside the motor vehicle.

11. The method of claim 8, wherein the range is further determined as a function of a charge state of the electrochemical energy storage device of the motor vehicle.
