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,
a thermal connection to a geothermal temperature control device for controlling a temperature of the charging station by geothermal energy,
a heat exchanger or heat pump for exchanging thermal energy between a coolant in the charging station and the geothermal energy of the thermal connection in order to control the temperature of the coolant, and
a pump configured to circulate the coolant in the charging station to and from (i) the heat exchanger or heat pump, (ii) an electronics system of the charging station for cooling the electronics system, and (iii) the charging connection for cooling the charging connection.

2. The charging station as claimed in claim 1 , 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.

3. The charging station as claimed in claim 2 , 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.

4. The charging station as claimed in claim 3 , wherein the pump is a first pump that is configured to convey the coolant in the coolant circuit to the heat exchanger or to the heat pump and back to the coolant circuit.

5. The charging station as claimed in claim 4 , 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.

6. The charging station as claimed in claim 5 , 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.

7. The charging station as claimed in claim 5 , wherein the fluid of the geothermal fluid circuit is a saline liquid.

8. The charging station as claimed in claim 1 , wherein the coolant of the coolant circuit is a water/glycol mixture.

9. 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.

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

11. The charging station as claimed in claim 1 , wherein the charging connection is cooled by the geothermal temperature control device.

12. The charging station as claimed in claim 1 , wherein the charging connection is a charging cable that includes a connector that is configured to be releasably connected to a vehicle that includes the at least one electrical energy store that is to be charged.

13. The charging station as claimed in claim 1 , further comprising channels in the electronics system of the charging station through which the coolant flow.

14. The charging station as claimed in claim 1 , wherein the electronics system of the charging station comprises a first connection to the electrical connection, and a second connection to a coolant circuit of the charging station, wherein the pump is configured to circulate fluid through the coolant circuit of the charging station.

15. The charging station as claimed in claim 1 , wherein the pump is positioned outside of the heat exchanger or heat pump.
