The present application claims the priority of German patent application No. 102023118367.2, filed on Jul. 11, 2023, which is expressly incorporated herein by reference in its entirety.
The invention relates to a housing for a charging station and a charging station having such a housing.
Charging stations, in particular fast charging stations for vehicles with an electric drive, are becoming increasingly important. The use of such a charging station should be as simple and convenient as possible for the user. In known charging stations, the length of a charging cable is selected in such a way that the charging cable does not touch the ground where the charging station is installed when it is not in use-if a charging plug of the charging cable is arranged on the charging station. This prevents the charging cable from being soiled and/or damaged by the ground. It also prevents a vehicle from driving over the charging cable and/or parking on it. The disadvantage of this is that the resulting limited length of the charging cable restricts the radius of action of the charging station, in particular a distance between a charging socket of the vehicle to be charged and the charging station. With the known charging stations, it is thus necessary to park the vehicle exactly relative to the charging station, as otherwise the charging plug cannot be arranged in the charging socket.
The invention is thus based on the object of creating a housing for a charging station and a charging station having such a housing, wherein the disadvantages mentioned are at least partially eliminated, preferably avoided.
The object is solved by providing the present technical teaching, in particular the teaching of the independent claims and the embodiments disclosed in the dependent claims and the description.
The object is solved in particular by creating a housing for a charging station with an opening cladding element delimiting at least one charging cable opening. The housing has at least one charging cable arm, which is configured to support a charging cable of the charging station, which charging cable is guided through the at least one charging cable opening, at least in some areas. In particular, the at least one charging cable arm is configured to accommodate and/or guide at least some areas of the charging cable of the charging station, which charging cable is guided through the at least one charging cable opening. Furthermore, the at least one charging cable arm is rotatable relative to the opening cladding element about an axis of rotation, wherein the axis of rotation is at least locally perpendicular to the opening cladding element. In addition, the at least one charging cable arm is clastic. Advantageously, an action radius of the at least one charging cable is increased by means of the at least one charging cable arm. In particular, the at least one charging cable is guided by means of the at least one charging cable arm in an elevated position to a motor vehicle to be charged, so that the at least one charging cable, in particular a charging plug of the at least one charging cable, can be arranged in a simple manner on the motor vehicle to be charged-in particular in a charging socket of the motor vehicle. In addition, the increased radius of action increases the number of possible parking positions for charging the vehicle at the charging station. Furthermore, the elastic design of the at least one charging cable arm allows the at least one charging cable arm to be bent in an at least partially reversible manner. Advantageously, in the event of a collision between a motor vehicle and the at least one charging cable arm, neither the motor vehicle nor the at least one charging cable arm is damaged.
In one embodiment, the at least one charging cable opening is designed as a polygon and/or arc polygon, in particular circular. In particular, the circular charging cable opening has a clear diameter which is at least as large, in particular exactly as large, as a diameter of the charging cable guided through the at least one charging cable opening.
In particular, the housing has a ceiling cladding element and at least one side cladding element, wherein one side cladding element of the at least one side cladding element is designed as the opening cladding element. In one embodiment, the housing has at least four side cladding elements, in particular exactly four side cladding elements.
In one embodiment, the opening cladding element is planar. In addition, the housing is designed in particular in such a way that when the housing is used as intended as the housing of a charging station, the opening cladding element is perpendicular to a ground where the charging station is set up, in particular perpendicular to a motor vehicle parking space at the charging station. In this case, the axis of rotation is aligned parallel to the ground.
In one embodiment, the at least one charging cable arm is arranged on the opening cladding element in such a way that, when the housing is used as intended, one end of the at least one charging cable arm facing the opening cladding element and the motor vehicle parking space are at a distance-measured vertically or perpendicularly-of 100 cm to 250 cm, in particular of 150 cm to 250 cm, in particular of 200 cm to 230 cm, in particular of 210 cm to 220 cm. In particular, the distance between the end of the at least one charging cable arm facing the opening cladding element and the motor vehicle parking space is selected such that a user of the charging station can walk upright under the charging cable arm-in particular without touching the charging cable arm.
In one embodiment, the housing encases an interior of a charging station at least partially, in particular completely, when used as intended, wherein in particular an installation surface of the charging station is not enveloped by the housing.
In particular, a material from which the at least one charging cable arm is made has a modulus of elasticity of 1000 N/mm2 to 1800 N/mm2.
According to a further development of the invention, it is provided that the at least one charging cable arm is displaceably connected to a housing body of the housing in such a way that it can optionally be arranged in an operating position and in a transport position. In particular, the at least one charging cable arm is connected to the housing body so as to be rotatable about the axis of rotation, the at least one charging cable arm can thus be rotated about the axis of rotation in order to arrange it optionally in the operating position and in the transport position. The housing body is formed in particular by the ceiling cladding element and the at least one side cladding element.
In particular, the at least one charging cable arm is connected to the opening cladding element in such a displaceable manner that it can be optionally arranged in the operating position or in the transport position.
In particular, in the operating position, the at least one charging cable arm extends away from the housing, in particular from the opening cladding element. In particular, in the operating position, the at least one charging cable arm is designed in such a way that, when the housing is used as intended, one end of the at least one charging cable arm facing away from the opening cladding element and the motor vehicle parking space are at a distance of 100 cm to 250 cm, in particular 150 cm to 250 cm, in particular 200 cm to 230 cm, in particular 210 cm to 220 cm. Alternatively or additionally, the at least one charging cable arm is almost parallel, in particular parallel, to the motor vehicle parking space in the operating position when the housing is used as intended. Alternatively or additionally, the at least one charging cable arm forms an angle of 10° to 50°, in particular 30°, with the opening cladding element in the operating position.
In the context of the present technical teaching, an imaginary charging cable arm path is considered for determining the angles, wherein the imaginary charging cable arm path is determined by a straight line through the end of the at least one charging cable arm facing away from the opening cladding element and the end of the at least one charging cable arm facing the opening cladding element.
In particular, in the transport position, the at least one charging cable arm rests at least partially against the housing, in particular against the opening cladding element. Advantageously, this enables compact transportation of the housing. It is also possible to make use of the inherent elasticity of the at least one charging cable arm and to attach it to the housing, for example with a strap or similar, in order to achieve the most compact shape possible in the transport position.

The charging cable cut-out is aligned with the at least one charging cable opening. Advantageously, the at least one charging cable can thus be routed directly and protected from an interior of the charging station through the at least one charging cable opening into the at least one charging cable arm.
According to a further development of the invention, it is provided that the at least one charging cable arm has a charging cable fixing element at an end facing away from the opening cladding element.
In particular, the charging cable fixing element is arranged to prevent movement of a charging cable supported by the at least one charging cable arm relative to the at least one charging cable arm in at least one direction. Advantageously, twisting and/or friction of the at least one charging cable in the at least one charging cable arm can at least be reduced, in particular prevented, by means of the fixing element.
According to a further development of the invention, it is provided that the at least one charging cable arm has a length of 80 cm to 150 cm, in particular of 100 cm to 130 cm, in particular of 110 cm.

The object is also solved by creating a charging station having a housing according to the invention or a housing according to one of the embodiments described above. The charging station also has at least one charging cable, wherein the at least one charging cable is guided out of the charging station through the at least one charging cable opening. Furthermore, the at least one charging cable is at least partially supported by the at least one charging cable arm. In connection with the charging station, the advantages already explained in connection with the housing apply in particular.
In electrical engineering, a charging station is any device or electrical system, in particular stationary or mobile, which is used to supply energy to mobile battery-powered devices, machines or motor vehicles by simply 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 referred to as “electric charging stations” and can include several charging points. High performance charging systems or high power charging system (HPC systems) such as the combined charging system (CCS), which is widespread in Europe, arc particularly well known. With generic direct current charging, direct current from the charging station is fed directly into the vehicle's battery and provided by a powerful rectifier, preferably of the charging station, from the power grid or by large buffer accumulators at solar charging stations, for example. There is a battery management system in the vehicle that communicates directly or indirectly with the charging station to adjust the current and voltage or to terminate the process when a predetermined capacity limit is reached. Power electronics are usually located in the charging station. Since the direct current connections of the charging station are connected directly to the corresponding connections of the traction battery-without a detour through an AC/DC converter of the vehicle-high charging currents can be transmitted with low losses, which enables short charging times.
In one embodiment, the charging station is designed as a charging column. In particular, the charging station has at least one charging point, in particular exactly one charging point or exactly two charging points.
In particular, the charging station is designed as a fast charging station. In one embodiment, the charging station is designed as a battery-supported charging station, in particular as a battery-supported fast charging station.
In one embodiment, the at least one charging cable has a protective sheathing that at least partially encases the at least one charging cable. In particular, the at least one charging cable does not have the protective sheathing in the area of the at least one charging cable arm. In particular, the protective sheathing is only formed in an area of the at least one charging cable that is not supported by the at least one charging cable arm. In particular, the protective sheathing is formed between a charging plug of the at least one charging cable and the end of the at least one charging cable arm, which end faces away from the opening cladding element, in particular the charging cable fixing element.
In a further embodiment, the charging station, in particular the housing, has a charging plug suspension in which the charging plug of the at least one charging cable can be arranged when the at least one charging cable is not in use. In particular, a length of the at least one charging cable is selected such that the at least one charging cable does not touch the ground when not in use—and thus when arranged in the charging plug suspension.
In a further embodiment, the charging station has two charging points and thus two charging cables and two charging cable arms, wherein a first charging cable is at least partially supported by a first charging cable arm and a second charging cable is at least partially supported by a second charging cable arm. In particular, the charging station has the opening cladding element with two charging cable openings. Alternatively or additionally, in the operating position, the two charging cable arms form an angle of 80° to 160°, in particular 120°. Alternatively or additionally, the two charging cable arms are almost parallel, in particular parallel, to each other in the transport position and/or form an angle of at most 10°. Alternatively or additionally, the two charging cable arms are designed such that a first end of the first charging cable arm facing away from the opening cladding element and a second end of the second charging cable arm facing away from the opening cladding element are at a distance of 200 cm to 300 cm, in particular 260 cm. Alternatively or additionally, the two charging cable arms are designed such that a first end of the first charging cable arm facing the opening cladding element and a second end of the second charging cable arm facing the opening cladding element are at a distance of 50 cm to 100 cm, in particular 74 cm. Advantageously, this makes it possible to charge two vehicles simultaneously in a simple and convenient manner and without a prescribed alignment of the vehicles relative to each other and/or relative to the charging station.
