Description

[0001] The present invention relates to a charging station for an electric vehicle charging station. The present invention also relates to a corresponding electric vehicle charging station. State of the art

[0002] In electrical engineering, a charging station is any stationary device or electrical system that supplies energy to mobile battery-operated devices, machines, or motor vehicles simply by plugging or unplugging the power cable, without having to remove the energy storage device—such as the traction battery of an electric car. Charging stations for electric cars are also colloquially referred to as "charging stations" and can include multiple charging points, which, depending on their design, are referred to as "charging columns."

[0003] Particularly well-known in this area are direct current fast charging systems (high-performance charging, HPC), such as the so-called combined charging system (CCS) widespread in Europe. In direct current charging, direct current from the charging station is fed directly into the vehicle, provided by a powerful rectifier from the power grid or by large buffer batteries at solar charging stations. The vehicle contains a battery management system that communicates with the charging station to adjust the current or terminate the process when a capacity limit is reached.

[0004] The power electronics required for this are typically integrated into the charging station according to the state of the art and can handle a power limit of up to 50 kW. Since the charging station's DC connections are directly connected to the corresponding connections of the traction battery, high charging currents can be transmitted with low losses, enabling short charging times.

[0011] The invention provides a charging station for an electric charging station, as well as a corresponding electric charging station according to the independent claims.

[0012] The proposed approach is based on the realization that electric charging stations and so-called charging parks will be built in the future, among other places, at rest areas and other locations not covered by urban lighting concepts. However, in many cases, adequate lighting is required to operate charging stations.

[0013] The installation of separate conventional lanterns according to the state of the art is expensive and generally undesirable for design reasons.

[0014] An advantage of the solution according to the invention lies in the use of modern lighting technology, which allows both to provide lighting with functional significance and to guide the user through the charging process by means of light signals and at the same time to create a characteristic behavior and appearance with recognition qualities.

[0015] Further advantageous embodiments of the invention are specified in the dependent patent claims. For example, a charging station according to the invention can fulfill a "lantern function" for ambient lighting, have a status light, or a DC meter. Short description of the drawings

[0016] An embodiment of the invention is illustrated in the drawings and is described in more detail below. Fig. 1 shows the perspective view of a charging station according to the invention. Fig. 2 shows the perspective view of an LED of the charging station. Fig. 3 shows the exploded view of the front housing of the charging station. Fig. 4 shows the exploded view of a boom plate of the charging station. Fig. Figure 5 shows the exploded view of the upper end of the charging station. Fig. 6 shows the exploded view of the entire charging station. Fig. 7 shows a first detail of the charging station without housing. Fig. 8 shows a second detail of the charging station without housing. Fig. 9 shows a third detail of the charging station with housing. Embodiments of the invention

[0017] Fig. Figure 1 illustrates the housing and individual components of the inventive lighting concept using the exemplary charging station (10) of an electric charging station (not shown in its entirety). Visible in this view are, in particular, an alternately illuminated plug holder (11) and an in-plane switching (IPS), glare-free, projected-capacitive touchscreen (13) for controlling the charging station (13). In this case, the touchscreen features 4 mm thick tempered glass and a luminance of 800 cd / m². 2 The figure also shows a viewing window (14) for reading the direct current supplied by the charging station (10) as well as a concrete base (15) which is in this case designed as a prefabricated component.

[0018] The design of the plug holder (11) is particularly characteristic of the present invention, the LED (16) of which is Fig. 2. The LED (16) preferably reacts to the state of the plug - i.e., whether it is plugged into the holder (11) - or the state of the charging process. A distinction is made between the conceivable cases of no user in the vicinity, a user being detected, the charging process being prepared, or charging in progress. These changes in state can be indicated to the user, for example, by flashing, changing color, or brightness. This is achieved by a light strip behind a transparent first glass pane (17) with a recess for the plug profile, against which the plug holder (11) is mounted. It is understood that the light strip may instead encircle the plug holder (11), for example in a groove open at the top, without departing from the scope of the invention.

[0019] As a supplement, the Fig. 3 reproduced status light (12), which signals - preferably also by means of a light-emitting diode - whether the charging station (10) is available.

[0020] Fig. 4 shows a further lighting unit (19) integrated into the lateral outrigger plates (18) of the charging station (10), which emits a uniformly dimmable light with a maximum luminous flux of 600 lm. The lighting unit (19) is designed here in the form of a light strip, which has a fixing pin on the front side for fixing the lighting unit (19) to the lower edge of the respective outrigger plate (18). Recessed fixing sections under the last LEDs serve to cover further, edge-mounted fixing sections. On the side of the outrigger plate (18), a recess is provided for accommodating the lighting unit (19), with depressions for fixing and accommodating the associated cable. The outrigger plates (18), which are designed here as a resin plate (sheet molding compound, SMC), also accommodate a Fig. 5 shown upper cable holder (20) between them.

[0021] Fig. 6 draws the viewer's attention to a single or multi-part second glass pane (21), which is preferably laminated to the screen (13) and, if appropriate, to the light strip of the plug holder (11).

[0022] Below the Fig. 7 illustrated plug holder (11) finally there is a Fig. 8 and Fig. 9 shows the display (23) of the calibrated DC meter (22) which is separate from the screen (13) and which is visible from the outside either through the second glass pane (21) mentioned, possibly laminated to the display (23), or through an integration exposed to the outside.
