Description

The field of technology

The technical solution relates to a method of creating a connection point for a charging station for electrically powered vehicles containing a rechargeable battery source and a connection point for this charging station. Charging station, or charging stations may include charging stations for electrically powered vehicles containing a rechargeable battery source, such as electric cars, electric motorcycles, electric bicycles, etc.

Current state of the art

The current solution to the preparation and construction of charging infrastructure, especially for electric cars, usually involves the installation of a separate high-current cable from the switchboard for each electric car charging station and the creation of a concrete foundation at the charging station installation site.

Charging stations normally have only one input for a high-current cable up to a maximum cross-section of 10 mm ² , so it is not possible to simply pull a thicker cable and loop the stations.

In this situation, the preparation and construction of a charging infrastructure for electric cars is financially expensive, which is especially evident when building a charging infrastructure or preliminary preparations for this charging infrastructure, including several charging stations for electric cars in one area, such as parking lots, parking areas, etc. The goal of this technical solution is to substantially eliminate the disadvantages of the current state of the art.

The essence of the technical solution

The goal of this technical solution is achieved by the below-described method of creating a connection point for a charging station for electrically powered vehicles containing a rechargeable battery source and a connection point for this charging station. It describes the method of creating a connection point for a charging station for electrically powered vehicles containing a rechargeable battery source connected to the switchboard for charging stations by at least one high-current cable, guided below ground level, the essence of which consists in the fact that in the area where the charging stations are located, the excavation in in the terrain, lay at least one uninterrupted high-current cable with a cross-section of up to 50 mm ² led to at least one place intended for the installation of a charging station. At the place designated for the installation of the charging station, a cable reserve of a high-current cable is created in the length necessary for connection to the charging station above the ground level or a cable reserve of an unbroken high-current cable in a loop, in the length necessary for connection to the charging station above the ground level. Advantageously, the cable reserve of the high-current cable or the cable reserve of the unbroken high-current cable in the loop is formed in a length reaching at least 0.3 m above ground level, most preferably 1 m above ground level. The cable reserve of a high-current cable or an unbroken high-current cable in a loop is stored in a case with a length of at least 500 mm and a diameter of at least 250 mm at one end, which can be closed with a fixed lid. The casing is installed in a vertical position in the trench on a water-permeable bed with a casing length of at least 500 mm, the trench with the high-current cable is filled in and the terrain is compacted at least around the casing to a thickness of at least 0.3 m.

Preferably, the case is formed by a plastic sewer pipe of type PVC 400 x 938 x 1,000 SN4, which can be closed with a plastic sewer lid designed for a wheel pressure of 1.5 t.

Preferably, together with the high-current cable, at least one unbroken communication cable is laid in the trench and led to at least one place intended for the installation of the charging station, while the cable reserve of the high-current cable or the unbroken high-current cable in the loop creates a cable reserve of the communication cable or unbroken communication cable from the communication cable. cable in a loop, in the length needed to connect to the charging station above ground level. Advantageously, the cable reserve of the communication cable or the cable reserve of the unbroken communication cable in a loop is formed in a length reaching at least 0.3 m above ground level, most preferably 1 m above ground level.

This cable reserve of the communication cable or the unbroken communication cable in the loop is stored in the case in which the cable reserve of the power cable or the unbroken power cable in the loop is stored.

Preferably, a grounding strip passing through at least one place designated for the installation of a charging station is placed in the trench, while at the place designated for the installation of the charging station, a grounding conductor is brought out and placed in the casing from the grounding strip in the length necessary for connection to the charging station above ground level. Preferably, the grounding conductor is brought out in a length reaching at least 0.3 m above ground level, most preferably 1 m above ground level.

Said objective is also achieved by a connection point for a charging station for electrically powered vehicles containing a rechargeable battery source, the essence of which consists in the fact that it is formed by a case with a length of at least 500 mm and a diameter of at least 250 mm at one end of which can be closed with a fixed lid. The casing is placed in a vertical position on a water-permeable bed with a casing length of at least 500 mm in terrain compacted to a thickness of at least 0.3 m. A cable reserve of at least one high-current cable, or an unbroken high-current cable in a loop, with a cable cross-section of up to 50 mm ² , in the length necessary for connection to the charging station above ground level, is stored in the case. Advantageously, the cable reserve of the high-current cable or the cable reserve of the unbroken high-current cable in the loop is formed in a length reaching at least 0.3 m above ground level, most preferably 1 m above ground level.

Preferably, the case is formed by a plastic sewer pipe of type PVC 400 x 938 x 1,000 SN4, which can be closed with a plastic sewer lid designed for a wheel pressure of 1.5 t.

Advantageously, a cable reserve of at least one communication cable or an unbroken communication cable in a loop, in the length necessary for connection to the charging station above ground level, is stored in the case of the cable reserve of the high-current cable, or of the unbroken high-current cable in a loop. Advantageously, the cable reserve of the communication cable or the cable reserve of the unbroken communication cable in a loop is formed in a length reaching at least 0.3 m above ground level, most preferably 1 m above ground level.

Preferably, a grounding wire is stored in the housing in the length necessary for connection to the charging station above ground level, which is connected to the grounding strip stored near the housing. The grounding conductor preferably reaches a length of at least 0.3 m above ground level, most preferably 1 m above ground level.

Overview of images on drawings

The technical solution is explained in more detail in fig. 1 in the accompanying drawing, which schematically shows the connection and connection point for a charging station, as well as multiple charging stations, including the connection of the charging station, the connection to the switchboard, as well as the termination of the connection.

Implementation examples

The given examples of implementation are described with reference to fig. 1. The picture is created for illustration in such a way that it shows the switchboard 7, then the housing 6 in the preparation phase, i.e. j. stretching the cable 1, 2 to the required length, then the coiled stored cable 1, 2, i.e. j. the case 6 is ready for the charging station 8 to be installed on it, then the case 6 on which the charging station 8 is placed, then the schematic presentation of three dots before the last connection point in the picture shows the possibility of multiplication, i.e. j. n charging stations 8 can be connected to cable 1, 2, respectively. it is possible to create n cases 6 ready for the future installation of the charging station 8, and finally at the end there is a safe termination of the cable 1, 2 with the possibility of installing the charging station 8. It is clear that using this summary image it is possible to illustrate without problems all the examples described below and overall possible realizations of this technical solution.

In one embodiment, one connection point for the charging station 8 can be created during the construction of the charging infrastructure, for example electric cars, or the preliminary preparation for this charging infrastructure.

In the usual way, a trench is created in the field to store the high-current cable 1, which will lead from the switchboard 7 to the place intended for the installation of the charging station 8 of electric cars. At least one unbroken high-current cable 1 with a cross-section of up to 50 mm ² is laid in the trench. In the place intended for the installation of the charging station 8, a cable reserve 11 of the high-current cable 1 is created in the length necessary for connection to the charging station 8 above the level 5 of the terrain. Advantageously, this cable reserve 11 of the high-current cable 1 is in a length reaching at least 0.3 m above the level 5 of the terrain, most preferably 1 m above the level 5 of the terrain.

The cable reserve 11 of the high-current cable 1 is stored in the case 6, in this particular example of the embodiment formed by a plastic sewer pipe of the PVC type 400 x 938 x 1000 SN4, which can be closed at one end with a plastic sewer lid designed for a wheel pressure of 1.5 t. which is not shown in the picture. The casing 6 is placed in a vertical position in an excavation on a water-permeable bed with a length of casing 6 of at least 500 mm. The case 6 is closed with a lid.

The trench with the high-current cable 1 is filled in and the terrain is compacted at least around the casing 6 to a thickness of at least 0.3 m.

In the given embodiment, one connection point for the installation of the charging station 8 is practically created.

The connection point itself is made up of a casing 6, in this particular embodiment made of a plastic sewer pipe of type PVC 400 x 938 x 1000 SN4, which can be closed at one end with a plastic sewer lid designed for a wheel pressure of 1.5 t. The casing 6 is placed in a vertical position on a water-permeable bed with a length of casing 6 of at least 500 mm in terrain compacted to a thickness of at least 0.3 m. A cable reserve 11 of at least one high-current cable 1 with a cross-section of up to 50 mm ² in the length required for connection to the charging station 8 above ground level 5 is stored in the case 6. Advantageously, this cable reserve 11 of the high-current cable 1 is in a length reaching at least 0.3 m above the level 5 of the terrain, most preferably 1 m above the level 5 of the terrain.

It is then possible to install a charging station for 8 electric cars at this connection point. The installation of the charging station 8 can be done immediately after creating this connection point or at any time later as needed. The actual installation of the charging station 8 at the connection point will be described in an example later in the text.

Thus, such a connection point can also advantageously serve as a preliminary preparation for the later installation of the charging station, while the case 6 closed with a lid, specifically in this example a plastic sewer lid designed for a wheel pressure of 1.5 t, provides sufficient protection for the prepared cable reserve 11, takes up minimal space, while it is not a significant obstacle for further terrain modifications or the creation of building structures in the vicinity of the connection point, and creates a practically immediately usable building foundation for the location of the charging station 8.

In addition, this technical solution provides the creation of a connection point for the charging stations 8 with low costs compared to the solutions applied so far, such as various concrete prefabs or the creation of cast concrete foundations for the charging stations. In the same way, the mentioned solution represents a saving of time, and thus also of financial costs, as charging stations 8 can be installed practically within one installation exit and these exits, compared to the standard solution that requires concreting, do not need to be repeated.

For completeness, in fig. 1 does not directly show the described example of the creation of one connection point, but such an embodiment is from fig. 1 obvious. Practically, it is represented by an assembly including a switchboard 7 and only one connection point for a charging station 8, in fig. 1 last case 6.

Cost savings and the efficiency of the solution become particularly significant when creating multiple connection points for charging stations for 8 electric cars.

In another embodiment, several connection points can be created for charging stations 8 of electric cars, which are preferably connected to one switchboard 7 for charging stations 8 by at least one high-current cable 1, routed below ground level 5.

In the area where the charging stations 8 of electric cars are located, at least one unbroken high-current cable 1 with a cross-section of up to 50 mm ² is laid in an excavation in the field, created in a conventional way, led to the place intended for the installation of the charging station 8 and at the same time passing through another at least one place or several places designated for the installation of several charging stations for 8 electric cars. At each place designated for the installation of the charging station 8, a cable reserve 11 of the high-current cable 1 is created in the length necessary for connection to the charging station 8 above the ground level 5. Advantageously, this cable reserve 11 of the high-current cable 1 is in a length reaching at least 0.3 m above the level 5 of the terrain, most preferably 1 m above the level 5 of the terrain.

At the places intended for the installation of charging stations 8, which are located along the length of the high-current cable 1, a cable reserve 11 of the unbroken high-current cable 1 is created in a loop, in the length necessary for connection to the charging station 8 above the ground level 5. Advantageously, this cable reserve 11 of the high-current cable 1 is in a length reaching at least 0.3 m above the level 5 of the terrain, most preferably 1 m above the level 5 of the terrain. The stated length of the cable reserve 11 in the loop is meant to be the length of the essentially stretched loop, in other words the length is reached from the point of view of the top point of the cable loop. At the last place designated for the installation of the charging station 8, a cable reserve 11 is created for the given high-current cable 1 at the end of the high-current cable 1 in the length necessary for connection to the charging station 8 above the ground level 5. Advantageously, this cable reserve 11 of the high-current cable 1 is in a length reaching at least 0.3 m above the level 5 of the terrain, most preferably 1 m above the level 5 of the terrain.

Each cable reserve 11 of the high-current cable 1 in the loop and the cable reserve 11 of the high-current cable 1 at the end of this cable 1 are stored in a separate casing 6, in this particular example of the embodiment formed by a plastic sewer pipe of the PVC type 400 x 938 x 1000 SN4, which is on at one end it can be closed with a plastic sewer lid designed for a wheel pressure of 1.5 t. Lid, lids are not shown in the picture. The casing 6 is placed in a vertical position in an excavation on a water-permeable bed with a length of casing 6 of at least 500 mm. The case 6 is closed with a lid.

The trench with the high-current cable 1 is filled in and the terrain is compacted at least around each casing 6 to a thickness of at least 0.3 m.

Each connection point is thus formed by a casing 6, in this particular example of implementation formed by a plastic sewer pipe of the type PVC 400 x 938 x 1000 SN4, which can be closed at one end with a plastic sewer lid designed for a wheel pressure of 1.5 t. The casing 6 is placed in a vertical position on a water-permeable bed with a length of casing 6 of at least 500 mm in terrain compacted to a thickness of at least 0.3 m. In the case 6, i.e. in this example in separate cases 6, the cable reserve 11 of at least one high-current cable 1 with a cross-section of up to 50 mm ² is then stored in a loop in the length necessary for connection to the charging station 8 above ground level 5 and the cable reserve 11 of the high-current cable cable 1 at the end of this cable 1 in the length necessary to connect to the charging station 8 above the level 5 of the terrain. Advantageously, this cable reserve 11 of high-current cable 1, both in a loop and single, has a length reaching at least 0.3 m above ground level 5, most preferably 1 m above ground level 5.

It is then possible to install a charging station for 8 electric cars at each connection point created in this way. The installation of the charging station 8 can be done immediately after creating this connection point or at any time later as needed. The actual installation of the charging station 8 at the connection point will be described in the text.

All the advantages of such a connection point, i.e. in this example each of the connection points, are the same as those mentioned in the example of creating one connection point according to this technical solution.

The solution is provided by the use of thicker or several thicker high-current cables 1 up to a cross-section of 50 mm ² . Specifically, as an example, they can be cables of type NAYY 1 x 25 rope or NAYY 4 x 50 rope, or cables of type AYKY, CYKY or N2XH depending on the environment where they are stored. It is important, however, that cables with a cross-section of up to 50 mm ² are used, with the fact that for a larger number of charging stations 8, several cables 1 are installed per sector. Ideal for outdoor use is the NAYY 1 x 25 rope type cable, which when pulled, for example, in the number of 4 pcs, is sufficient to secure a loop of 100 - 125 A depending on the length of the loop. If not 4 pcs (L1-L3+N) are pulled from these cables, but 8 pcs, it is possible to protect the loop with a double current.

In another embodiment, with reference to the described embodiments, at least one unbroken communication cable 2 can be advantageously placed in the trench together with the high-current cable 1 and led to the place intended for the installation of the electric car charging station 8 or to at least one or more other places intended for installation charging station 8, and at the same time passing through at least one other or more places intended for the installation of several charging stations 8 of electric cars. In such an embodiment, with the cable reserve 11 of the high-current cable 1, or the unbroken high-current cable 1 in a loop, the communication cable 2 creates a cable reserve 21 of the communication cable 2, or the unbroken communication cable 2 in a loop, in the length necessary for connection to the charging station 8 above level 5 terrain. Advantageously, the cable reserve 21 of the communication cable 2 or the cable reserve 21 of the unbroken communication cable 2 is formed in a loop with a length reaching at least 0.3 m above ground level 5, most preferably 1 m above ground level 5.

This cable reserve 21 of the communication cable 2 or the unbroken communication cable 2 in the loop is stored in the case 6, in which the cable reserve 11 of the high-current cable 1 or the unbroken high-current cable 1 in the loop is stored.

Thus, in accordance with the example describing the creation of one connection point for the charging station 8, the communication cable 2 is also routed together with the high-current cable 1, and also in accordance with the example describing the creation of several connection points for several charging stations, it is also routed together with the high-current cable 1 also communication cable 2.

It also applies that the stated length of the cable reserve 21 in the loop is meant to be the length of the basically stretched loop, in other words the length is reached from the point of view of the top point of the cable loop.

Most advantageously, the communication cable 2 can be specifically an exterior cable of the cat 5e FTP type, which serves to control the charging points from the superior energy management system installed in the switchboard 7.

It is advantageous if a grounding strip 3 passing through at least one place designated for the installation of a charging station 8 for electric cars is placed in the excavation at the same time, while at the place designated for the installation of a charging station 8, a grounding conductor 4 is brought out of the grounding strip 3 to the casing 6 and placed in the length necessary to connect to charging station 8 above level 5 terrain. Preferably, the grounding conductor 4 is brought out in a length reaching at least 0.3 m above ground level 5, most preferably 1 m above ground level 5.

In the possible embodiments of the connection point according to that technical solution, therefore, the grounding conductor 4 in the length necessary for connection to the charging station 8 above the ground level 5 can also be stored in the housing 6. Preferably, the grounding conductor 4 is brought out in a length reaching at least 0.3 m above ground level 5, most preferably 1 m above ground level 5.

In one specific embodiment, for example, one switchboard 7 with one circuit breaker is provided, the value of which can be increased according to the number of already installed charging stations 8, and one or more high-current cables 1 and at least one communication cable 2 emanate from it. The central control unit is located in the switchboard 7 charging stations, for example the AgeVolt Smart System of the manufacturer AgeVolt, which controls the power supplied to the charging stations 8.

At the place of installation of the charging station 8, which can also be a double charging station, etc., the casing 6 is installed according to this technical solution. High-current and, if necessary, also communication cabling 1, 2 enters this housing 6, on which a corresponding cable reserve 11, 21 is formed, which is only twisted in the housing 6 and the cabling 1, 2 continues into the next housing 6. In the housing 6 is an iron structure is installed, which is just below the closing lid of the case 6. In the particular most advantageous embodiment, the case 6 is then a plastic sewer pipe of the PVC type 400 x 938 x 1000 SN4, on which the corresponding plastic sewer cover is mounted, usually sized for a wheel pressure of 1.5 t. This solution thus makes it possible to create a large number of places ready for the installation of charging stations 8 for charging using direct current as well as alternating current, i.e. AC and DC charging stations, which will, however, be limited in the group by the maximum value of the common circuit breaker. However, the savings on cabling for long routes of, for example, an outdoor parking lot, compared to previous solutions, is considerable, and the price of such a preparation is significantly less than a separate copper cable, usually of the CYKY 5 x 6 type, with a concrete base for each charging station 8.

For this kind of preparation, the charging station 8 can then be installed in any place with the fact that the circuit breaker for the entire loop is turned off, the hatch is opened, the coiled high-current cable 1 and the communication cable 2, if present, are clicked through. High-current cable 1 is either, in the case of installation of the so-called wall boxes with terminals up to 5 x 6, still in the case 6 is connected (looped) to e.g. an ordinary plastic electrical box, in which the number of circuit breakers is required according to the number of charging points above the surface, and from which separate copper cables usually of the CYKY 5 x 6 type lead, or the high-current cables 1 from the housing 6 are pulled directly into the charging station 8, the so-called of the pillar type, which has sufficiently large terminals so that these high-current cables 1 can be looped here. The communication cable 2 and the grounding wire 4, if present, are also pulled out of the housing 6 and connected to the charging station 8. The actual installation of the charging station 8 then takes place in such a way that a steel structure is installed in the housing 6 under the lid, which strengthens the housing 6 and from which, usually four, threaded screws protrude upwards. A hole is created in the lid, or several holes, if necessary, for the passage of cables and holes for the specified threaded screws. Either a stand for charging stations 8 of the wallbox type (wall-mounted) or the pillar-type station itself is placed on the lid and is attached to the indicated threaded screws, i.e. practically directly to the indicated steel structure located in the case 6. The charging station 8 is set to the spirit level (plane), usually with leveling screws on the bottom of the charging station 8 and by pulling it to the lid of the case 6, the whole assembly acquires the necessary strength.

The proposed technical solution also allows for another way of installing the charging station 8. For example, when installing the DC charging station 8, usually four ground screws are drilled into the ground around the casing 6, with the size according to the type of the DC charging station 8. The ground screws themselves are then mounted on these ground screws DC charging station 8. As the space around the casing 6 is sufficiently compacted, the ground screws have sufficient load capacity for the installation of DC charging stations 8 with a weight of more than 1,000 kg.

The proposed technical solution provides a simplification of the construction of the pre-preparation of charging stations by using only products commonly available on the market, which are cheap and easily available, as they are also commonly used for other purposes, such as in the specific case of making the case 6 and its cover from a plastic sewer pipe of the type PVC 400 x 938 x 1,000 SN4, on which the corresponding plastic sewer cover designed for a wheel pressure of 1.5 t is mounted. Furthermore, by adapting the charging station 8 to the installation and looping of thicker high-current cables 1, the preparation becomes cheaper and easier. By creating only one circuit breaker/take-off point, the price and difficulty of building charging points for electric cars decreases, with the fact that using software, e.g. manufacturer AgeVolt, the charging points can be serviced from the energy point of view, i.e. j. dynamic distribution of charging power, etc., as well as in terms of settlement between owners, i.e. j. measurement of actual consumption for each charging station 8 in the system and separately.

In the same way as shown in fig. 1, several, in any number, separate high-current cables 1 can be routed, while they are all routed from the same switchboard 7, and appropriately, if necessary, communication cables 2 and grounding strips 3, which creates a separate sector for each such cable outlet 1 , 2. With the described solution, considering the individual technical parameters, it is possible to connect up to 50 charging stations 8 per sector, i.e. j. to one cable outlet 1, 2 from the switchboard 7, while maintaining a minimum guaranteed power of 6A per charging station 8. Therefore, 50 charging stations can subsequently be installed in each sector while maintaining a minimum guaranteed power of 6A per charging station 8 (if a larger guaranteed performance, it is necessary to install a smaller number of charging stations (8 per sector).

In each case 6, a cable reserve 11, 21 of both the power cable 1 and the communication cable 2 is left in the length necessary for connection to the charging station 8 above ground level 5. Advantageously, these cable reserves 11, 21 are at least 0.3 m above ground level 5, most preferably 1 m above ground level 5. For cable loop 1, 2, as mentioned, the length is reached from the point of view of the top point of the cable loop.

Furthermore, a grounding conductor 4, for example specifically of the AlMgSi8 type, is brought out from below into the housing 6 from the grounding strip 3, in the length necessary for connection to the charging station 8 above the ground level 5. Advantageously, this conductor 4 has a length reaching at least 0.3 m above ground level 5, most preferably 1 m above ground level 5. Generally, the grounding conductor 4 is not led out of the grounding strip 3 in a loop, as is the case with the power cable 1 and the communication cable 2, respectively.

The casing 6 is most advantageously made of a plastic smooth sewer pipe type PVC 400 x 9.8 x 1000 SN4 installed in a vertical position in a pipe length of at least 500 mm. Under case 6, it is necessary to create e.g. sand bed for better water drainage. The top of the casing 6 will be closed with the lid of the sewage pipe at ground level 5. The high-current cable 1, for example, specifically of the NAYY 4 x 50 type, is wound in the case 6 in the form of a spiral around the inner circumference of the case 6, and the input and output of the high-current cable 1 is in the lower part of the case 6. If necessary, a hole can be cut into the case 6, possibly also more openings as needed, for the purpose of the entry of cables 1, 2 at a different height of the housing 6, than the entry through the lower open end of the housing 6. The cable reserve 21 of the communication cable 2 and the reserve of the grounding conductor 4, for example specifically of the AlMgSi 8 type, is realized as , so that in the future it will be possible to pull them above the ground for the purpose of connection to the charging station 8. It is important that neither the high-current cable 1 nor the communication cable 2, if present, must not be within one route, that is, in this particular example of several subsurface cable reserves 11, 21 interrupted and will go as a whole. In the last case, the high-current cable 1 and the communication cable 2, if present, are terminated practically with half the cable reserve 11, 21 against the cable reserve 11, 21 in the loop, above the level 5 of the terrain, in the length necessary to connect to the charging station 8 above the level 5 terrain, preferably in a length reaching at least 0.3 m above the 5 terrain level, most preferably 1 m above the 5 terrain level. Both the high-current cable 1 and the communication cable 2, if present, must be insulated at the end in the last casing 6, for example specifically with protection IP x 8. The requirement to insulate the free ends of the cables 1, 2 generally applies in every case and example of the implementation of this technical solution.

For the sake of completeness, in embodiments that will not include the communication cable 2, it is possible to provide communication for the control of the charging stations 8, for example, by available wireless transmission technologies.

The given examples of implementation are presented as illustrative and do not exhaust all alternatives of possible implementations.

As mentioned, the casing 6 is most advantageously made of a plastic sewer pipe of the type PVC 400 x 938 x 1000 SN4, on which the corresponding plastic sewer cover designed for a wheel pressure of 1.5 t is mounted. This is due to the lowest cost and common availability of this product. However, it is also possible to use similar elements, possibly also made of other materials, which meet the parameters, as an example of the specified plastic pipe and lid. Pipes can be used, for example, or constructions of a similar shape (regardless of the type of cross-section) enabling the routing of cabling, made of metal materials, composite materials, plastics, prefabricated materials or other materials guaranteeing the necessary strength. With regard to the dimensions of the housing 6, this can practically have the smallest usable dimensions, an inner diameter of at least 250 mm, a length of at least 500 mm. The smallest length of the casing 6, by which it is installed in the terrain, is practically at least 500 mm. The lid of the case 6 can be load-bearing/walkable or it can only be dimensioned for the carrying capacity of the charging station 8, if it is attached to the case 6 and its lid, or the lid 6 can only have the function of covering the inner space of the case 6. It is obvious that in case, if the charging station is attached to the housing 6 and its lid, the lid of the housing 6 will be firmly attached to the housing 6. The choice mentioned depends on the specific requirements for the arrangement of the charging location.

The mentioned elements can be as commonly available on the market, as it is also possible to produce these elements specifically for this use, which may increase their price, but this solution as a whole will still be more cost-effective compared to the solutions described in the prior art. The proposed technical solution is not limited only to the specific examples described, which are given only as an illustration to illustrate the essence of this technical solution. Analogously, it is possible to create a number of other implementations of this technical solution, all of which will fall within the scope of the claims.

Also, the listed examples of implementation are described on the example of charging stations 8 electric cars. In general, it is possible in the given examples for the charging station 8, or charging stations 8 consider charging stations for electrically powered means of transport containing a rechargeable battery source, such as, in addition to electric cars, also electric motorcycles, electric bicycles, etc.
