Abstract

At present, there are essentially only two options available to users of electric vehicles to charge them, namely public charging stations or the private parking space provided with a power connection (eg garage or carport). The present invention discloses a new solution to this problem. This consists of a current bridge that spans the public traffic (walkway, bike path, green area, etc.) starting from a private ground at an altitude so that no traffic hazard occurs, but at the same time allows a power cable to bring the vehicle to its batteries electrically to load.

Description

background

There is a great deal of economic and environmental interest in the area of mobility to replace internal combustion engines with electric motors. The increasing number of electrically powered vehicles raises the question of how the accumulators present in these vehicles can be charged. An accumulator is a battery that is rechargeable. There are currently two main options available to users, namely public charging stations or the powered private parking space (e.g., garage or carport).

However, especially in urban areas, only a small minority of vehicle owners have a private parking space, such as a car park. a garage or carport that could be provided with a power supply. Instead, in most of these areas, the majority of roadside vehicles are in front of single or multi-family homes.

For these users, apart from the impractical and only a small number of existing public electricity charging stations, there is currently no solution to enable them to charge the batteries of their vehicles.

In principle, it would be possible to lay a power cable from the respective house, using a suitable cover, over the sidewalk and / or bike path and / or green areas. However, this solution limits the use of the affected pedestrian and / or cycle paths and / or green areas, raises questions of safety and is probably difficult to reconcile with the Highway Code. Alternatively, you might consider installing curb sockets. In this case, however, a parking right would have to be granted. Furthermore, it would be necessary to carry out civil engineering work, as walking and / or cycle paths and / or green areas would have to be dredged and reclosed to lay the power cable. This would be associated with high costs.

The invention

The present invention discloses a solution to this technical problem which is simple to implement and avoids the disadvantages of the possibilities disclosed in the prior art.

The solution consists of a current bridge, which, for example, starting from a private land (plot, house wall, etc.), the public transport (walkway, bike path, green areas oa) spans at an altitude so that no traffic hazard occurs, but at the same time allows a power cable to be brought to the vehicle to charge its batteries electrically.

The current bridge comprising at least one carrier ( 1 ), at least one boom ( 2 ), which is at a first end ( 3 ) with the carrier ( 1 ), and at least one electrically conductive power cable ( 4 ), which along the boom ( 2 ) and at a second end ( 5 ) of the jib ( 2 ) allows a current decrease.

Preferably, the boom ( 2 ) of the current bridge can be rolled up or folded, for example by suitable joints and / or hinges, and thus can be folded one or more times. Alternatively, the boom ( 2 ) be designed so that it can be disassembled into individual elements (for example, by plug element). Furthermore, it is possible that the boom ( 2 ) can be pushed together telescopically. The aforementioned possibilities of opening and closing the current bridge can also be used in combination.

Furthermore, the carrier ( 1 ) and / or boom ( 2 ) also be designed in a removable manner. This disassembly is, preferably, possible without the use of a tool. In a preferred embodiment, carriers ( 1 ) and / or boom ( 2 ) portable and transportable. In a further preferred embodiment, only a suspension device is fixedly mounted in which then carrier ( 1 ) and / or boom ( 2 ) can be hung.

The goal is the boom ( 2 ) preferably only unfolded during the charging process to use. Otherwise, this can be made as small and compact as possible on the carrier ( 1 ) or be completely removed. In this way, the spanning of public transport (sidewalk, bike path, etc.) is only temporary nature.

The carrier ( 1 ) can also be used with more than one boom ( 2 ), for example two, three, four, five, six or more. This is advantageous if several vehicles are to be loaded from one location. Especially in multi-family houses, this embodiment is preferred because multiple users can load their vehicles from one power access point.

The entire current bridge is preferably made weatherproof. In particular, this applies to all moving parts such as hinges, rollers, etc. and the electrical components (power cables, plugs, etc.).

The current bridge can be made of different materials. Plastics and light metals such as aluminum are particularly suitable. you have sufficient strength for the low weight to be worn.

The current bridge can furthermore have holders for the temporary or permanent attachment of the at least one electrically conductive power cable (FIG. 4 ) respectively. The at least one electrically conductive power cable ( 4 ) can preferably be guided on the inside, whereby it is particularly well protected from the weather.

The current bridge may further comprise one or more pivot joints, in particular in the region of the carrier ( 1 ). This ensures that the unfolded boom ( 2 ) can be aligned, for example, in the direction of the zuladenden vehicle. Furthermore, it can also be advantageous in the folded state, the boom ( 2 ) to twist. This may be advantageous, for example in the case of the use of weather protection devices, such as housings or covers.

Basically, at least one carrier ( 1 ) available. This is designed so that it can be mounted on a wall, a post or similar, preferably on private land. Alternatively, this carrier ( 1 ) also be attached to another power source, for example to a street lamp. Alternatively, this carrier ( 1 ), for example, be anchored in the ground. A combination of these two mounting options is also possible, ie an anchorage in the ground and further stabilization over, for example, a wall, an existing post or guying.

Preferred is an embodiment in which the current bridge exactly one carrier ( 1 ). Since only one carrier is present, the influence of the current bridge on the public space is particularly low in this embodiment, since there is no ground contact in public space.

To protect the current bridge from being used by unauthorized persons, it may comprise at least one locking device. This can be achieved, for example, by the fact that the unfolding / pulling apart of the boom ( 2 ) and / or turning relative to the carrier ( 1 ) is blocked. Furthermore, the closing device can serve to enable or prevent the flow of current. These mechanisms can be achieved by several locking devices or combined in one locking device.

The current bridge preferably comprises a device for manual and / or automatic winding of the power cable ( 4 ). This is particularly useful if the user has the power cable ( 4 ) at the end ( 5 ) of the boom still a piece and would like to lead to his vehicle.

Preferably, the current bridge comprises a device for the manual and / or automatic folding and / or unfolding of the current bridge, in particular the cantilever ( 2 ).

The current bridge comprises, preferably, a control device for monitoring the flow of current quite generally and, in particular, the charging process. In this case, parameters such as, for example, the current flow, the amount of current, the charging duration, the charging current and / or the charging voltage are monitored and, if appropriate, the current flow / charging process is interrupted when preset threshold values are reached and / or exceeded and / or undershot. This control device also serves to prevent power theft. The decoupling of the cable from the vehicle to be loaded can be detected and the charging process interrupted. Furthermore, the control device may also include a plurality of electricity meters.

The power cable used is, preferably, cut-resistant and, for example by a metal insert, protected against vandalism. It also includes a connector system, which is tuned to the vehicle to be charged.

The goal of the current bridge is the carrier ( 1 ) and cantilevers ( 2 ) in such a way that public space, for example a sidewalk and / or cycle path and / or a green strip, are bridged without restricting the use of this public space. The necessary minimum height of the boom ( 2 ) above ground can be taken from local regulations. The length of the boom ( 2 ) results from the distance to be bridged to the vehicle to be loaded. Typically, the current bridge has a height of 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4.0 or 5.0m.

The present invention also encompasses the use of the current bridge according to the invention for the electrical charging of accumulators, preferably of accumulators in motor vehicles. Particularly preferred is a use of the power bridge for charging accumulators of motor vehicles which are on the roadside where the boom ( 2 ) serves the public space, for example, a walkway and / or bike path and / or a green belt to bridge.

The advantages of the present invention are many. The power bridge according to the invention allows a plurality of vehicle owners who, for lack of their own private parking space, such as a garage or carport, are currently excluded from efficient and convenient use of an electric vehicle to change to such a vehicle. Only minor construction measures are necessary, which every private person can essentially carry out himself. This is a great advantage over alternative solutions such as a curb socket, which require civil engineering work and thus the digging and closing of walkways and / or bike lanes and / or a green belt. Furthermore, the present invention enables a simple and simple charging of the batteries in the life of the vehicle in front of your own door.
