Description

The present invention relates to a charging station for electric vehicles.

The ever-increasing spread of electric vehicles leads to the need for a suitably adapted charging infrastructure. It has been found that in addition to charging in the private sector or in underground garages there is a need to give users the opportunity to charge their vehicles, even in public spaces, especially in parking lots.

Therefore, in the future, a large area of public space needs to be created for users to charge their electric vehicles. Without such constant availability of charging stations, the necessary acceptance for electric vehicles can not be created.

In public space, however, in addition to the pure supply of energy even more requirements for charging stations, in particular, safety aspects are of utmost importance. Destruction of charging stations can lead to considerable risks, since in the charging stations electrical cables with voltages of a few hundred volts to several thousand volts are arranged, which must be able to carry currents in the ampere range, to allow rapid charging of electric vehicles.

There are basically two risks for damage to charging stations: accidents and vandalism. While vandalism has so far been limited primarily to destroying charging cables and damaging the housing due to kicking or paint, unwanted driving around of charging stations by vehicles poses a greater risk.

While in classical facilities in parking lots such as ticket machines or barrier systems, the consequential risk of a "knocked over" or severely damaged technical equipment is low, at a charging station a strong damage by driving around the same, especially an exposed the power cable must be prevented mandatory.

Out WO 2010/115926 a charging station is known, which tries to solve the existing problem in that a trough-like ramming protection made of metal is arranged on a floor arranged on the concrete base, which is to protect the inner electronics of the charging station and over which the actual outer lining of the charging station is slipped.

This already known from the prior art solution has in particular the disadvantage that on the one hand, the entire charging station can still be easily moved by a vehicle, so that the main connecting wires are exposed, and on the other hand, that continue within the reinforced area of the Rammschutzes the electronic components are arranged. If the crash protector is bent in the event of damage, it can still be in contact with the internal electronics and thus create an additional source of danger instead of reducing the risk.

Particularly disadvantageous is the risk of a damaged charging station when it forms a charging station with an integrated roof, in particular a solar roof, in the manner of a carport. In this case, the entire charging station with roof possibly unstable, since the known crash protection covers only the lower part of the charging station.

Based on the known prior art, the object of the present invention was thus to provide a charging station which overcomes the disadvantages of the prior art and which in particular has a secure and stable state, which protects the charging station from damage and possibly the loads of a roofing can record.

This object is achieved by a charging station for electric vehicles, comprising a foundation section and a functional section, wherein the foundation section is arranged below the ground level starting and extends up to a height of at least 40cm, at least 60cm or at least 80cm above the ground level upwards, said functional elements of the loading station are arranged exclusively in the function section arranged above the foundation.
