Description

Charging station for electric vehicles with a foundation section and a

function section

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, the possibility must be created for users to charge their electric vehicles over a large area in public space in the future. 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. A destruction of

Charging stations can lead to considerable risks, since in the charging stations electrical cables with voltages of a few hundred volts up to the part of several thousand volts are arranged, which must be able to carry currents in the ampere range, in order to allow rapid charging of the electric vehicles.

There are basically two risks for the damage of 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, this is an unintentional one

Avoiding the charging stations by vehicles is the greater risk. While in classic facilities in parking lots like

Parking ticket machines or barriers the consequential risk of a "run over" or severely damaged technical equipment is low, a strong damage by bypassing the same, in particular a bare of the power cable, must be mandatory at a charging station.

From WO 2010/115926 a charging station is known, which tries the

existing problem solved by the fact that a trough-like ram protection of metal is arranged on a arranged on the floor concrete base, which is to protect the inner electronics of the charging station and over which the actual outer panel 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 within the reinforced area the ramming protection continue 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, if this forms a charging station with 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, therefore, the object of the present invention was to provide a charging station, which overcomes the disadvantages of the prior art and in particular a safe and stable state that the charging station before

Protects damage and, if necessary, can absorb the loads of a canopy.

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 , wherein the functional elements of the loading station are arranged exclusively in the above the foundation

Roof can then be stored, if necessary by means of further struts, by the particularly stable foundation section according to the invention. It is obvious that the foundation section can be made of different materials. However, reinforced concrete has proven to be particularly advantageous. However, the foundation section may also be formed from bolted in the ground steel girders or be formed of a concrete foundation from which steel girders extend upwards.

According to the invention is crucial that, in contrast to the known charging stations, a foundation section is formed in which no functional elements such as energy storage, power electronics, etc. are arranged, but a stiffer compared to the other elements, heavier and more vibration-resistant section is provided, which can absorb the kinetic energy from accidents.

It may be provided in particular that the

Foundation section comprises a passage for electrical lines, in particular begins below the ground level and ends at the upper end of the foundation section.
