Abstract

The invention relates to a system for inductive power transfer to vehicles driving or standing on a surface of a route, in particular to road automobiles, wherein the system includes a primary winding structure for generating an alternating electromagnetic field, wherein a field volume (FV) is assigned to the primary winding structure, wherein the system includes at least a part of a first heating system, wherein elements of the first heating system which are arranged within the field volume (FV) are non-metallic elements. Further, the invention relates to a pavement slab assembly and a method of operating a system for inductive power transfer.

Claims

1. A system for inductive power transfer to vehicles driving or standing on a surface of a route, comprising:

a primary winding structure for generating an alternating electromagnetic field, wherein a field volume is assigned to the primary winding structure; and

at least a part of a first heating system, wherein elements of the first heating system which are arranged within the field volume are non-metallic elements,

wherein the system comprises at least a part of at least one other heating system, wherein all elements of the at least one other heating system are arranged outside the field volume.

2. The system according to claim 1, wherein the first heating system and/or the at least one other heating system comprises a hydronic heating system.

3. The system according to claim 2, wherein the elements of the first heating system and/or the elements of the at least one other heating system comprise at least one transporting means for an operating fluid.

4. The system according to claim 3, further comprising at least one connecting means for connecting the at least one transporting means to an external fluid supply.

5. The system according to claim 1, wherein the other heating system is an electric heating system.

6. The system according to claim 1, wherein at least a part of the first heating system is arranged under and/or over the primary winding structure.

7. The system according to claim 1, further comprising a cable bearing element, wherein at least a part of the first heating system is arranged under and/or over the cable bearing element.

8. The system according to claim 1, further comprising a cable bearing element, wherein at least a part of the first heating system is arranged within the cable bearing element.

9. The system according to claim 8, wherein the cable bearing element comprises receiving means for receiving at least a part of the first heating system.

10. The system according to claim 1, further comprising at least one thermal insulation element, wherein the at least one thermal insulation element is arranged under the part of the first heating system and/or the at least one other heating system.

11. The system according to claim 1, further comprising at least one temperature sensor for sensing a temperature of a reference surface and/or at least one snow sensor and/or at least one ambient temperature sensor.

12. A pavement slab assembly for a route for vehicles driving or standing on a surface of the route, comprising a system according to claim 1, wherein the pavement slab assembly consists at least partially of pavement material.

13. A method of operating a system according to claim 1, comprising activating the first heating system and/or the at least one other heating system.

14. The method according to claim 13, the method further comprising operating the first heating system and/or the at least one other heating system, depending on a temperature of a reference surface of the primary winding structure and/or an ambient air temperature and/or depending on a presence of a winter contaminant on the reference surface.

15. The method according to claim 13, further comprising operating the first heating system and/or the at least one other heating system in response to a winter contaminant being predicted.

16. The method according to claim 13, further comprising operating the first heating system and/or the at least one other heating system such that a temperature of at least a portion or point of a reference surface of the primary winding structure is higher than or equal to a predetermined temperature.

17. A method for building a system for inductive power transfer to vehicles driving or standing on a surface of a route, the method comprising:

providing a primary winding structure, wherein a field volume is assigned to the primary winding structure;

providing at least a part of a first heating system;

arranging elements of the first heating system such that elements of the first heating system which are arranged within the field volume are non-metallic elements; and

providing at least a part of at least one other heating system, wherein all elements of the at least one other heating system are arranged outside the field volume.

18. A method of building a pavement slab assembly, the method comprising:

providing a casting mould;

providing a primary winding structure, wherein a field volume is assigned to the primary winding structure;

arranging the primary winding structure within the casting mould;

casting pavement material into the casting mould;

providing at least a part of a first heating system;

arranging elements of the first heating system within the casting mould, wherein elements of the first heating system which are arranged within the field volume are non-metallic elements; and

providing at least a part of at least one other heating system, wherein all elements of the at least one other heating system are arranged outside the field volume.

19. A method for building a route for vehicles driving or standing on a surface of the route, the method comprising:

providing a plurality of pavement slab assemblies according to the method of claim 18; and

installing the pavement slab assemblies on a prepared base or foundation such that a driving surface or standing surface for vehicles which are driving or standing on the route is provided.
