Description

[0001] The present invention relates to a charging station for electric cars. State of the art

[0002] In electrical engineering, a charging station is any stationary device or electrical system that serves to supply energy to mobile battery-powered devices, machines, or motor vehicles simply by placing them on the charging station or plugging them in, without necessarily having to remove the energy storage device—such as the traction battery of an electric car. Charging stations for electric cars are sometimes also called "electric vehicle charging stations" and can include multiple charging points.

[0003] Particularly well-known here are high-performance DC fast charging (HPC) systems, such as the combined charging system (CCS) widely used in Europe. In standard DC charging, direct current from the charging station is fed directly into the vehicle. This is achieved by a high-performance rectifier supplied by the power grid or by large buffer batteries at, for example, solar charging stations. The vehicle contains a battery management system that communicates directly or indirectly with the charging station to adjust the current or to terminate the charging process when a capacity limit is reached.

[0004] The power electronics are typically located in the charging station. Since the DC connections of the charging station are directly connected to corresponding connections of the traction battery, high charging currents can be transmitted with minimal loss, enabling short charging times, but also generating considerable heat.

[0005] Standard charging stations for electric vehicles occupy a considerable amount of space, especially when they integrate a battery. They typically use large cabinets or are designed as charging stations ranging from 1.8 m to 2.2 m in height. These stations usually have one or two doors to ensure maintenance and accessibility. These doors are often weak points in terms of water ingress, etc. Vandalism is also easier through the doors, as they reveal vulnerable areas to vandals.

[0006] CN 2 05 674 884 U discloses a charging station or column with a cube-shaped housing.

[0007] DE 10 2011 056 651 A1, EP 2 875 989 A1 and US 2011 / 0 140 657 A1 concern charging stations or charging columns with a housing to protect against environmental influences or precautions against vandalism.

[0009] US 2015 / 0042276A1 discloses a charging station for electric vehicles with a charging interface attached to a structure. The charging interface has a cover that is pivotally attached to a housing of the charging interface.

[0011] US 5 573 319 A reveals a transformer housing.

[0014] The invention provides a charging station for electric cars according to the independent claim.

[0015] One advantage of this solution lies in its compact design, which does not obstruct, or only minimally obstructs, visibility in road traffic. Furthermore, a charging station according to the invention is easy to open yet resistant to environmental influences. In particular, it is easily accessible for simple maintenance and installation. Finally, vandals would find it extremely difficult to open the charging station.

[0016] Further advantageous embodiments of the invention are specified in the dependent claims. For example, it can be implemented in the form of a cube with dimensions of approximately 1.2 m by 1.2 m and a height of 1.3 m, which is visible above ground, independent of the foundation. The cube is provided with a cover, similar to a piece of furniture covered with a slipcover.

[0017] Four sides and an upper section of one side, to which hinges are attached, constitute the aforementioned hood, which can be opened. Its dimensions are such that even a single person can manage this. By removing the hinges, the hood can also be completely detached. This largely eliminates gaps where water could enter. Furthermore, the opening mechanism is difficult for vandals to decipher. Brief description of the drawings

[0018] An embodiment of the invention is shown in the drawings and is described in more detail below. Fig. Figure 1 shows the perspective view of a charging station according to the invention. Fig. Figure 2 shows the unfolded charging station in a semi-transparent view. Embodiments of the invention

[0019] Fig. Figure 1 illustrates the basic structure of a charging station (10) with a rectangular base plan with a side length of 1.2 m and a height of 1.3 m. A large part of the charging station (10) is clearly covered by a removable hood (17), which is only interrupted by inwardly offset grilles in the area of ​​a provided cooling system (18) for the charging station (10).

[0020] Fig. Figure 2 illustrates the functional mechanism of the hood (17), whose edge sealing surface (11) interacts with a sealing strip (12) that surrounds the charging station (10). The seal (11, 12) formed by both components when the hood (17) is fully in contact is separated in the illustrated state, since the hood (17) has been pivoted backward about its horizontal axis of rotation (13) by means of hinges not shown in the drawing. How Fig. As can be inferred from Figure 2, the axis of rotation (13) is selected by a suitable arrangement of the hinges such that the seal (11, 12) is compressed largely vertically when the hood (17) is closed, without the sealing surface (11) and sealing strip (12) shifting significantly relative to each other when pressed. Below the axis of rotation (13), the sealing strip (12) and the sealing surface (11) also exhibit inclined sections (14) such that the seal (11, 12) is compressed when the hood (17) is closed. For the same purpose, the sealing surface (11) is inclined inwards in the upper area of ​​the hood (17).

[0021] The fixed rear wall (15) of the charging station (10) has an inwardly offset and in Fig.The cooling slots thus conceal a stage (16) which supports the recooling unit (18) equipped with suitable hose connections. In a maintenance-friendly manner, the recooling unit (18) remains in position even when the cover (17) is opened as shown, for example, to blow out or otherwise clean the stage (16). The well-protected system can therefore be easily serviced by a single person. For more complex repairs – for example, to the power electronics or buffer storage of the charging station (10) – the cover (17) can also be completely removed from the base unit from the position shown, if necessary.
