Abstract

A charging station system, in particular for electric vehicles is described, wherein the charging station system has at least one housing. The charging station system also has a plurality of main components. The housing and the main components are standardized in such a manner that the main components can be arranged modularly in the housing. An associated method for constructing a charging station is also described.

Claims

1. A charging station system comprising:

at least one housing;

a plurality of main components located inside the at least one housing and including;

a first main component having a first power supply module to output a first direct current line branch and a second power supply module to output a second direct current line branch, wherein the first main component and the second main component are configured to be connected to a transformation station to receive an alternating current input;

a second main component having;

a first cooling module that includes a first coolant line with a first cooling power, and

a second cooling module that includes a second coolant line with a second cooling power that is same or different from the first cooling power;

a first charging pole connected to the first cooling module of the second main component by the first coolant line; and

a second charging pole connected to the second cooling module of the second main component by the second coolant line;

wherein;

each one of the first cooling module and the second cooling module is configured to cool a maximum of three power supply modules together with three charging poles,

the first charging pole is connected to the first power supply module of the first main component by the first direct current line branch, and

the second charging pole is connected to the second power supply module of the second main component by the second direct current line branch.

2. The charging station system as claimed in claim 1, wherein each of the plurality of main components has a control box.

3. The charging station system as claimed in claim 1, wherein the charging station system includes the transformation station.

4. The charging station system as claimed in claim 1, wherein the at east one housing is manufactured from steel sheet, steel plates or concrete.

5. The charging station system as claimed in claim 1, wherein the at least one housing has at least one door.

6. The charging station system as claimed in claim 1, wherein the at least one housing includes a first housing and a second housing which is situated next to or above the first housing.

7. A charging station system comprising:

at least one housing; and

a plurality of main components located inside the at least one housing and including;

a first main component having;

a first cooling module that includes a first coolant line with a first cooling power, and

a second cooling module that includes a second coolant line with a second cooling power that is same or different from the first cooling power;

a second main component and a third main component configured to be connected to a transformation station to receive an alternating current input, wherein;

each of the second main component and the third main component have a respective first power supply module to output a respective first direct current line branch and a respective second power supply module to output a respective second direct current line branch, and

each of the second main component and the third main component are connected to the first cooling module by the first coolant line;

a first charging pole connected to the second cooling module of the first main component by the second coolant line and connected to the respective first power supply module of the second main component by the respective first direct current line branch;

a second charging pole connected to the second cooling module of the first main component by the second coolant line and connected to the respective second power supply module of the second main component by the respective second direct current line branch; and

a third charging pole connected to the second cooling module of the first main component by the second coolant line and connected to the respective first power supply module of the third main component by the respective first direct current line branch.

8. A charging station system comprising:

at least one housing; and

a plurality of main components located inside the at least one housing and including;

a cooling component that includes first and second cooling modules having a respective cooling power same or different from each other over a respective coolant line;

a first power component, a second power component, and a third power component configured to be connected to a transformation station to receive a respective alternating current input, wherein;

each of the first power component, the second power component, and the third power component have a respective first power supply module to output a respective first direct current line branch and a respective second power supply module to output a respective second direct current line branch, and

the respective first power supply module and the respective second power supply module of the second power component and the third power component are connected to the first cooling module and the second cooling module respectively by the respective coolant line;

a first charging pole connected to the respective first power supply module of the first power component by the respective first direct current line branch;

a second charging pole connected to the respective second power supply module of the first power component by the respective second direct current line branch;
