Abstract

A method for the thermal pre-conditioning of a vehicle having an electric drive unit and an electrical energy reservoir. The method includes at least the following step: the thermal pre-conditioning of a component of the vehicle while the electrical energy reservoir of the vehicle is connected to the external electrical energy supply.

First claim

What is claimed is:

1 . A method for thermal pre-conditioning a vehicle having an electric drive unit, an electrical energy reservoir and a component that is configured to store thermal energy, wherein the method comprises the steps of:
thermally pre-conditioning the component of the vehicle by heating or cooling the component while the electrical energy reservoir of the vehicle is connected to an external electrical energy supply; and transferring the stored thermal energy from the thermally pre-conditioned component to either an interior compartment of the vehicle or the electrical energy reservoir during operation of the vehicle and while the vehicle is disconnected from the external electrical energy supply, wherein the component has a primary function other than the storage of thermal energy.

2 . The method according to claim 1 , wherein the thermal pre-conditioning of the component is carried out by the external electrical power supply.

3 . The method according to claim 1 , wherein the component comprises a body part of the vehicle and/or a shell of the vehicle and/or a part of the electric drive unit of the vehicle.

4 . The method according to claim 1 , wherein the thermal pre-conditioning of the component of the vehicle by the external electrical power supply occurs while the vehicle is in a charging position.

5 . The method according to claim 1 , wherein the thermal pre-conditioning of the component of the vehicle during a charging of the electrical energy reservoir occurs by means of the external electrical power supply.

6 . The method according to claim 1 ,
wherein the component of the vehicle is configured as a shell component of the vehicle, wherein, in addition to the shell component, a shell structure of the vehicle comprises a further shell component, wherein the shell is thermally insulated against the further shell component by a thermal insulation; and/or wherein the component of the vehicle is configured as a body part of the vehicle, wherein, in addition to the body part, a body of the vehicle comprises a further body part, wherein the body part is thermally insulated against the further body part by a thermal insulation.

7 . The method according to claim 1 , wherein the vehicle comprises a heating and/or cooling system, wherein the thermal pre-conditioning of the component is carried out by the heating and/or cooling system such that during the thermal pre-conditioning of the component, the heating and/or cooling system is fed through the electrical energy reservoir and/or the external electrical energy supply in such a way that the component is thermally pre-conditioned by the heating and/or cooling system.

8 . The method according to claim 1 , wherein the method further comprises:
either heating or cooling a vehicle cabin of the vehicle and/or of the electrical energy reservoir of the vehicle by means of the thermally pre-conditioned component during an operation of the vehicle and/or while driving the vehicle.

9 . The method of claim 1 , wherein the component does not form part of the electric energy reservoir.

10 . The method of claim 1 , wherein the component includes channels through which a fluid can pass for transferring thermal energy from the component to a cooling circuit of the vehicle.

11 . A system for the thermal pre-conditioning of a vehicle having an electric drive unit, an electric energy reservoir and a component that is configured to store thermal energy, wherein the system is configured for:
thermally pre-conditioning the component of the vehicle by heating or cooling the component while the electrical energy reservoir of the vehicle is connected to an external electrical energy supply; and transferring the stored thermal energy from the thermally pre-conditioned component to either an interior compartment of the vehicle or the electrical energy reservoir during operation of the vehicle and while the vehicle is disconnected from the external electrical energy supply, wherein the component has a primary function other than the storage of thermal energy.

12 . The vehicle comprising the electric drive unit, the electric energy reservoir, and the system of claim 11 .

13 . The system of claim 11 , wherein the stored thermal energy from the thermally pre-conditioned component is transferred to the interior compartment of the vehicle during operation of the vehicle and while the vehicle is disconnected from the external electrical energy supply.

14 . The system of claim 11 , wherein the component comprises a thermally insulated shell of the vehicle.

15 . The system of claim 11 , wherein the component does not form part of the electric energy reservoir.

16 . The system of claim 11 , wherein the component includes channels through which a fluid can pass for transferring thermal energy from the component to a cooling circuit of the vehicle.

17 . A non-transitory machine-readable storage medium storing a computer program configured to carry out a method in a vehicle having an electric drive unit, an electric energy reservoir and a component that is configured to store thermal energy, the method comprising the steps of:
thermal pre-conditioning the component of a vehicle by heating or cooling the component while the electrical energy reservoir of the vehicle is connected to an external electrical energy supply, and transferring the stored thermal energy from the thermally pre-conditioned component to either an interior compartment of the vehicle or the electrical energy reservoir during operation of the vehicle and while the vehicle is disconnected from the external electrical energy supply, wherein the component has a primary function other than the storage of thermal energy.

18 . The non-transitory machine-readable storage medium of claim 17 , wherein the stored thermal energy from the thermally pre-conditioned component is transferred to the interior compartment of the vehicle during operation of the vehicle and while the vehicle is disconnected from the external electrical energy supply.

19 . The non-transitory machine-readable storage medium of claim 17 , wherein the component comprises a thermally insulated shell of the vehicle.

20 . The non-transitory machine-readable storage medium of claim 17 , wherein the component does not form part of the electric energy reservoir.
