Abstract

A charging station, such as, in particular, a charging column, includes an electrical connection for supplying current/voltage to the charging station, a charging connection for connecting at least one electrical energy store that is to be charged, and a thermal connection to a geothermal temperature control device for controlling the temperature of the charging station by geothermal energy.

First claim

What is claimed is:

1 . A charging station comprising:
an electrical connection for supplying current/voltage to the charging station, a charging connection configured for connecting to at least one electrical energy store that is to be charged, and a thermal connection to a geothermal temperature control device for controlling a temperature of the charging station by geothermal energy.

2 . The charging station as claimed in claim 1 , further comprising a heat exchanger or a heat pump, by which the temperature of a coolant is controlled by geothermal energy, wherein the coolant circulates in the charging station and controls the temperature of an electronics system or other components of the charging station.

3 . The charging station as claimed in claim 2 , wherein the heat exchanger or the heat pump has a coolant connection for connecting to a charging-station-internal coolant circuit, and the heat exchanger or the heat pump has a geothermal connection for connecting to a geothermal fluid circuit.

4 . The charging station as claimed in claim 3 , wherein the coolant circuit is configured in such a way that the temperature of either the electronics system or other components of the charging station is controlled by the coolant flowing through the coolant circuit.

5 . The charging station as claimed in claim 4 , further comprising a first pump configured to convey the coolant in the coolant circuit to the heat exchanger or to the heat pump and back to the coolant circuit.

6 . The charging station as claimed in claim 5 , wherein the geothermal fluid circuit comprises at least one ground borehole in a region of the charging station, in which ground borehole fluid lines are arranged such that the temperature of a fluid flowing through the fluid lines is controlled by the geothermal energy.

7 . The charging station as claimed in claim 6 , further comprising a second pump configured to convey the fluid in the fluid lines of the geothermal fluid circuit to the heat exchanger or to the heat pump and back to the geothermal fluid circuit.

8 . The charging station as claimed in claim 6 , wherein the fluid of the geothermal fluid circuit is a saline liquid.

9 . The charging station as claimed in claim 2 , wherein the coolant of the coolant circuit is a water/glycol mixture.

10 . The charging station as claimed in claim 1 , wherein the charging station or the electronics system of the charging station or the components of the charging station are configured to be cooled or heated by the geothermal energy.

11 . The charging station claimed in claim 1 , wherein the charging station is a charging column.
