Abstract

An apparatus for charging a plurality of electric vehicles, wherein the apparatus has a charging module, wherein the charging module is operatively connected to a cooling component, wherein the cooling component is designed in such a way that, for the purpose of carrying away the waste heat from the charging module, a medium which carries along the waste heat is transported through a line which is routed in the ground.

First claim

What is claimed is:

1. Apparatus for charging a plurality of electric vehicles, wherein the apparatus comprises:
a charging module; and
a cooling component operatively connected to the charging module,
a charging line extending from and connected to the cooling component, the charging line being configured to be connected to one of the electric vehicles for charging the electric vehicles,
a cooling line having a first end that is connected to the cooling component, a second end that is configured to be routed in the ground, and a hollow fluid-carrying passage extending between the first and second ends, wherein neither the first end nor the second end of the cooling line is configured to be connected to the plurality of electric vehicles,
the cooling component being configured to (i) receive waste heat via a medium in said charging line, and (ii) deliver the waste heat to a liquid medium contained in the cooling line, which is routed in the ground, such that the cooling line transfers the waste heat into the ground as a result of surface contact between the cooling line and the ground.

2. Apparatus according to claim 1 , wherein the cooling line is a plastic pipe.

3. Apparatus according to claim 1 , wherein the cooling line is a metal pipe.

4. Apparatus according to claim 1 , wherein the cooling line has ribs.

5. Apparatus according to claim 1 , wherein the cooling line is laid in a meandering manner in the ground.

6. Apparatus according to claim 1 , wherein the cooling line is at least partially surrounded by one or more sheathings.

7. Apparatus according to claim 6 , wherein the one or more sheathings which at least partially surrounds the cooling line include at least two sheathings fitted at regular intervals.

8. Apparatus according to claim 6 , wherein the one or more sheathings include at least two sheathings and wherein the distances between the sheathings which at least partially surround the cooling line increase as the distance from the charging module increases.

9. Apparatus according to claim 6 , wherein the one or more sheathings include at least two sheathings and wherein the distances between the sheathings which at least partially surround the cooling line decrease as the distance from the charging module increases.

10. Apparatus according to claim 1 , wherein the cooling line is not directly connected to the plurality of electric vehicles.

11. Apparatus according to claim 1 , wherein the cooling line and the charging line are separate lines that are interconnected via the cooling component.
