Abstract

A charging device includes an electrically chargeable vehicle and a stationary charging station. In order to establish a galvanic connection between the vehicle and the charging station, the vehicle and the charging station each include at least two electrical contacts being in mutual contact for establishing the galvanic connection between the vehicle and the charging station. The contacts are each elongate. The contacts have specified lengths that are less than the width of the vehicle. The contacts of the vehicle are disposed in a fixed manner on the vehicle. The contacts of the charging station are movable at least vertically. The mutually complementary contacts are disposed in such a way that the contacts extend transversely to each other in a predefined charging position of the vehicle for establishing of the galvanic connection.

First claim

The invention claimed is:

1. A charging station for a vehicle, the charging station comprising:
four electrical contacts of the charging station for establishing electrical connections between the vehicle and the charging station by mutual contact between said four electrical contacts of the charging station and four complementary electrical contacts of the vehicle;
said four electrical contacts of the charging station being movable at least vertically;
said four electrical contacts of the charging station having lengths being less than a width of the vehicle;
said four electrical contacts of the charging station and the four complementary electrical contacts of the vehicle each having a respective longitudinal axis;
said longitudinal axes of said four electrical contacts of the charging station each being oriented transversely to a respective one of the longitudinal axes of the four complementary electrical contacts of the vehicle and said longitudinal axes of said four electrical contacts of the charging station each intersecting a respective one of the longitudinal axes of the four complementary electrical contacts of the vehicle at one respective point in a predefined charging position of the vehicle;
said four electrical contacts of the charging station lying in a shared plane and being disposed lengthwise; and
said longitudinal axes of said four electrical contacts of the charging station together forming a rectangular shape or together forming a cross shape.

2. The charging station according to claim 1 , wherein said shared plane is a horizontal plane.

3. The charging station according to claim 1 , which further comprises a boom of the charging station for vertically moving said four contacts of the charging station.

4. An electrically chargeable vehicle, comprising:
four electrical contacts of the vehicle for establishing electrical connections between the vehicle and the charging station by mutual contact with four complementary electrical contacts of a charging station;
said four electrical contacts of the vehicle being fixedly disposed on the vehicle;
said four electrical contacts of the vehicle having lengths being less than a width of the vehicle;
the four electrical contacts of the charging station and said four complementary electrical contacts of the vehicle each having a respective longitudinal axis;
said longitudinal axes of said four electrical contacts of the vehicle each being oriented transversely to a respective one of the longitudinal axes of the four complementary electrical contacts of the charging station and said longitudinal axes of said four electrical contacts of the vehicle each intersecting a respective one of the longitudinal axes of the four complementary electrical contacts of the charging station at one respective point in a predefined charging position of the vehicle;
said four electrical contacts of the vehicle lying in a shared plane and being disposed lengthwise; and
said longitudinal axes of said four electrical contacts of the vehicle together forming a rectangular shape or together forming a cross shape.

5. A charging device, comprising:
a charging station according to claim 1 ; and
a vehicle according to claim 4 .

6. The vehicle according to claim 4 , wherein said shared plane is a horizontal plane.

7. The vehicle according to claim 4 , wherein said four electrical contacts of the vehicle are disposed on a roof of the vehicle and are freely accessible from above.
