Charging station for wired charging of an electric vehicle

The invention relates to a charging station for charging an electric vehicle and the charging station.

In charging stations for electric vehicles, especially for electric cars, a distinction is made between wired and wireless charging stations or charging operations. The wireless charging takes place inductively, so that the corresponding coil of the charging station, for example. Is directly below a surface of a parking space on which is off to charge the vehicle or embedded in the parking space can be ^¬ surface po sitioned. The wireless charging station is thus not a physical obstacle and is also inconspicuous in optical terms. In a wired situation, a charging cable of the charging station is connected to a corresponding input terminal of the electric vehicle. The charging cable is at charging stations ^¬ high power, ie at fast charging stations, on the side of the charging station firmly connected to the charging station or with their charging power source and on the other side with a

Plug completed. In particular, for AC charging stations a bushing may also be present at the loading column and the La ^¬ dekabel then has at both ends a plug. For wired charging, a distinction must be made between AC charging and DC charging. In AC charging, the charging station provides an alternating current, which is first rectified by a converter in the electric vehicle. When DC loading lie ^¬ fert the charging station the direct current with which the battery of the vehicle that is directly, without interposing a wide ^¬ ren power electronic component loaded. In a DC charging station, a significantly more powerful AC-DC converter is typically installed than is practical and possible in a vehicle. In contrast to the AC charging with charging times of currently about 4h to 8h, the goal of DC charging is usually the fast charging with charging times of about 15min to 30min for a charging capacity or energy of about 20kWh to 40kWh.

The electrical and electronic components (including housing and cooling), which are required for a DC charging station with an output power of 50kW to 100kW, take according to the current state of the art in air cooling, a volume of 0.5m ³ to 1.0m ³ and have a weight of several hundred kilograms. A complete DC charger therefore not be in a slim charging station with a mush ^¬ te and a depth of, for example, about 20cm to 30cm integrate as in AC charging.

It is therefore when DC charging over to accommodate the Leistungselektro ^{¬ technology} in a separate container or container and visible to use a charging station as in AC charging, this charging station only the charging cable and the charger ^¬ plug to the vehicle and a control unit contains.

However, the use of charging stations has the problem that they are usually freely accessible and in a more or less public space, so that they may be perceived as disturbing the environment, for example. Lack of sufficient integration into the cityscape. Furthermore, the charging stations are disadvantageous because of their relatively exposed position for safety and maintenance technical reasons.

It is therefore an object of the present invention to provide a charging station and charging station for charging an electric vehicle, which does not have the disadvantages mentioned. This object is achieved by the inventions specified in the independent claims. Advantageous embodiments emerge from the dependent claims. A charging station according to the invention for an electric vehicle can be connected to the electric vehicle for charging the electric vehicle via a charging cable. The charging station can be moved in and out with respect to a room, ie the charging station can be moved into the room and moved out of the room again.

The space may be, for example, a cavity enclosed by walls, wherein on one side of the cavity a possibly.

closable opening is provided through which the

Charging column can be moved in and out of the room. Also, the space of only at least one wall with a

Limited opening through which the charging station can be moved. This at least one wall is then, for example.

between the cavity and the footprint on which the

Electric vehicle for charging is off.

The charging station is retracted into the cavity in a first operating state. The first operating state is

in particular the idle state in which no electric vehicle is to be charged. In a second operating state, in which an electric vehicle is to be charged or is charged, the charging station is extended from the cavity.

Thus, there is only access to the charging station and it is only visible if an electric vehicle is to be charged. At any other time, apart from any maintenance work or the like, the charging station is located in the room, so it is neither a physical obstacle nor a visual impairment of the environment and is not to be damaged by external influences.

Ideally, the charging station does not have any electrical and electronic components that are directly required for charging

Components housed in the charging station such as. Power converters, filters and galvanic isolation. These components are in a separate container. The charging station has only the charging cable and a

Operating and communication device via which the

Charging is controlled and / or used for communication with the vehicle electronics, in particular with the battery ^¬ management system (BMS) of the vehicle. The to provide the correctly sized stream and the associated

Voltage required to charge the electric vehicle

Components are located exclusively in the container.

The charging station is thus essentially only an operating interface and a holding device for the charging cable for the plug. The charging cable is guided only through the Ladesäu ^¬ le and when no charging is suspended from this. Thus, the charging station is very light and it can be a volume very small size realized ^¬ the.

The operating unit is equipped with a display device and an input device, in particular a keyboard or buttons. The display device gives, for example, information about the state of charge and the charging process, etc. With the

Input device, an operator, eg. The driver of the electric vehicle, the charging process start, interrupt and stop and possibly make additional inputs such as the amount of money for which he wants to charge the battery of the electric vehicle.

The display device may be a touch-sensitive display, which simultaneously offers the functions of the display device and the input device described briefly above.

The charging station according to the invention for an electric vehicle has:

a charging station which can be moved in and out with respect to a first space according to the invention as described above, a drive device, in particular a lifting,

Sliding or folding device, to spend the

Charging station in and out of the cavity, and

- A container in which at least a portion of the immediately required for charging the electric vehicle electrical and / or electronic components is housed and with which the charging cable of the charging station is electrically connected. Furthermore, the charging station has a footprint on which the electric vehicle can be turned off to charge its battery. In the extended state from the room, the charging station is located directly next to or possibly even on the footprint. This charging station ensures due to the on and

extendable charging station a minimum impact on the environment and the best possible protection of the charging station from damage. The first room into and out of which the charging station can be moved, in a first embodiment in the ground, i.

under the ground surface, be provided. The term "ground surface" is to be understood in such a general way that, for example, road surfaces, the surface of a walkway, the earth's surface, the turf, etc. are also included. That The meaning of the term floor surface depends on the environment in which the charging station is located or at which location the charging station is to be sunk in the ground.

In a second embodiment, the first space is in or behind a wall that is substantially laterally adjacent to the charging station. This wall may be the outer wall of a building or a freestanding wall such as a

Be privacy screen.

In a third embodiment, the first room is in a ceiling which spans the charging station. Such a Case may, for example, occur when the charging station

inside a building such as in a parking garage

is installed and the charging station out of place or

Connection reasons better to arrange above the charging station.

The container may be located in a second cavity in the ground, in particular underground under a footprint for the charging electric vehicle.

Preferably, the container is in the same cavity

accommodated, in which the charging station is retractable, i.

Container and charging station are in the same,

common cavity.

In a special embodiment, the first cavity is located in the container, so that the charging station in the

Container is retractable. Thus, a compact unit of charging station and container is created, which can be easily installed and connected.

The container is designed in particular in terms of shape and material such that one inside the housing

arising heat as far as possible to the outside, eg. In

Soil, is derived. The container must therefore

preferably no cooling media, such as cooling water, are supplied from the outside. The container must only be connected to the local power supply network.

The outer wall of the container is ideally made

galvanized sheet steel.

The outer wall of the container has outer ribs, which ensure an enlargement of the surface of the container wall and thus improved heat dissipation.

Inside the container located, in the operating state of the charging station heat-releasing components are with the Exterior wall thermally connected. The thermal connection takes place in particular via heat conduction, for example by

thermal bridges in the form of cooling plates, the heat

connect dispensing elements to the container wall. The thermal connection can also be based on the effect of heat convection and be achieved by air or water cooling in the container, wherein the coolant, for example. Air or

Water, in turn transfers the absorbed heat to the container wall.

The container has a power connection, for example. A sealable screw, to which a power supply to supply the charging station with electrical energy

is connectable. Additionally or alternatively, a

Cable connection provided, to which the charging cable can be connected. A charging station having such a container can be delivered and connected ready-made, without having to intervene in the interior of the charging station during installation. In the alternative embodiment, in which, for example, the charging cable is firmly connected to the container or to the internal electronics, etc., the container would have to be delivered together with the cable. If the container had no power connection as described, the connection to the power supply would be much more complex.

Furthermore, the container has a hatch, in particular a maintenance hatch with which the container is opened and

can be closed. For example, the electrical and / or electronic components or parts thereof required directly for charging the electric vehicle can be lifted out of the container as a unit via this service hatch without having to disconnect electrical connection cables. Further, at least at partial removal of components, the container is accessible via the service hatch, so that

possibly necessary maintenance can be made. Container and charging station are preferably designed as a unit, for example. As a cuboid volume with a kind of access hatch, from which the loading unit is extendable, and positionable in a common to the first and the second cavity cavity.

Preferably, the container has only one

Power connection and no further connections. In this embodiment, in particular, the installation cost is minimal and the charging station is a fully integrated and erroneously preinstalled unit that is already completed as part of the production, they must be connected for installation only to an energy source, eg. The power grid.

The container may be housed in a building with a first room and a second room, wherein the two rooms may, for example, be adjacent. In this case, the container is accommodated in the first space and arranged such that at least part of the surface of the container,

in particular a side wall of the container, acts as a wall or floor heating for the second room.

That this side wall forms itself a wall or a floor of the second room or is integrated into the wall or the floor of the second room or the medium which passes through a wall or floor heating of the second room, at least in part by the container in operation the charging station generated heat heated.

To transfer the heat are located inside the container, heat in the operating state of the charging station

donating components thermally connected to the outer wall of the container, in particular via heat conduction and / or heat convection.

Advantageously, the charging station is designed as a DC charging station. With an AC charging station is a distinction between the charging station and the container with the power electronics components not necessary.

In summary, the invention offers the following advantages:

- Minimal disruption of the cityscape or the environment, since only when charging the absolute minimum, namely the charging station with control and communication unit and charging cable, is visible;

- the best possible vandalism and damage protection;

Soundproofing and damping by burial, i. no additional soundproofing measures are required;

- no external cooling device or no external

Cooling connections required because the waste heat through the container surface to the environment, eg. The soil or a building is discharged;

- Charging station consisting of extendable charging station and

Power electronics container may be suitable

be treated as a unit constructive design, especially in the case of a DC charging station;

- No or reduced requirements on the appearance of the bulk of the loading station, the container.

Further advantages, features and details of the invention will become apparent from the embodiment described below and with reference to the drawings.

FIG. 2 shows a charging station in a second embodiment,

1A shows a charging station 10 according to the invention with a likewise charging column according to the invention 100, a container 200 in which for charging a parked on a footprint 300 of the charging station 10 electric vehicle 20 required electrical and electronic components are housed, and a control unit 500th , among others controls and controls the charging process.

The electrical and electronic components are not shown here in detail, since it is known which

Components needed for an AC or DC charging process. For example. Depending on the type and performance of the charging process, these may include power electronics, iso-monitors, circuit breakers, galvanic isolation devices, AC-DC power converters, filters, etc.

Design of the electrical and electronic components for the present invention does not play a major role, these components are symbolically summarized in an electronic assembly 400, which is housed in the container 200.

The container 200 is located in an underground cavity 600, which is located in the case shown in Figure 1A immediately below the footprint 300 and the two Be ^¬ rich 601, 602, wherein the container 200 is positioned in the area 602. Depending on the spatial conditions, the container 200 may of course also be located elsewhere. However, the space below the footprint 300 is suitable for this purpose. Material and outer shape of the container 200 are so

designed that a heat generated in the interior of the container 200 via the container wall 201 to the environment, eg. The surrounding soil 40 can be discharged. The Container wall 201 is, for example, made of galvanized sheet steel, optionally with additionally applied outer ribs 202 for better heat dissipation.

The interior of the container 200 is designed so that heat-emitting elements, i. in particular the electrical and electronic components, transmit their heat to the container wall 201. This can be achieved by heat conduction, for example, by means of thermal bridges 203 in the form of cooling plates, which connect the heat-emitting elements 400 to the container wall 201. On the other hand, this can be achieved by heat convection, for example by means of air or water cooling in the container (not shown), wherein the respective coolant in turn transfers the heat absorbed to the container wall.

The charging station 100 has an operating device 110 with a display device 111 and an input device 112, for example a keyboard 112. The display device 111 is, for example, a display. In an advantageous embodiment, it is a touch-sensitive display so that it can simultaneously realize the functionalities of the display 111 and the keyboard 112. On the basis of the operating device 110, an operator, for example the driver of the electric vehicle 20 to be charged, can start the charging process, possibly interrupting and stopping and monitoring, and possibly make further inputs or retrieve information.

Furthermore, the charging station 100 has a charging cable 120. The charging cable 120 is terminated at one end with a charging plug 121 which is ver ^¬ bindable with a corresponding socket 21 of the electric vehicle 20 and above with its battery 22. The other end of the charging cable 120 is connected to the electronics assembly 400, which provides the electrical energy needed to charge the electric vehicle 20. For this purpose, the electronic assembly 400 is connected to a power supply 30, which may be connected, for example, to the public power grid. The charging station 100 is characterized in that it is retractable by means of a lifting device 700 in the cavity 600 of the charging station 10 and from this again extendable. This can be the same cavity 600, in which the container 200 is housed, wherein the charging station in the region 601 of the cavity 600 is retractable. The lifting device 700 is actuated by the control unit 500 and can, for example, operate in the manner of an electrically, hydraulically or pneumatically driven lifting platform.

FIGS. 1A and 1B show two operating ^{states of} the charging station 10. The operating state illustrated in FIG. 1B corresponds to the idle state of the charging station 10, in which there is no vehicle for charging in the charging station. In this case, the charging station 100 is in the cavity 601

retracted. The charging plug 121 is attached to a corresponding device 113 on the charging station 120. These

Device 113 may be, for example, a depression or trough into which the plug 121 can be inserted and optionally locked, or a hook or the like, on which the plug 121 can be suspended. At rest, the charging station 100 is neither a physical obstacle nor a visual impairment of the environment and is not damaged by external influences.

Located as in the second operating state of the charging station 10 shown in FIG. 1A

Electric vehicle 20 for charging on the footprint 300 of the charging station 10, the charging station 100 using the

Lifting device 700 caused by the control unit 500 from the cavity 601 extended. For example. can the

Control unit 500 may be connected to sensors 501 on the footprint 300, which signal the presence of a vehicle 20 on the footprint 300. Alternatively, the control unit 500 may also be at the behest of an operator of the charging station 10, the charging station 100 extending out of the cavity 601

trigger . The operator, for example, the driver of the electric vehicle 20, after the charging station 100 is extended, on the one hand grab the charging plug 121 and with the charging socket 21 of the

Electric vehicle 20 connect. On the other hand, the operator can start the charging process via the keyboard 112 of the operating device 110 of the charging station 100 and possibly parameter for the

Charging enter such as the desired amount of charge and / or a certain amount of money for which the operator would like to land the battery 22 of the electric vehicle 20. The display 111, the operator can see the state of charge of the battery 22 and possibly other parameters for charging as, for example, the time required to complete the charging, etc.

After completion of the charging process or at the behest of the operator or the operator of the charging station, the charging station 100 is moved back into the cavity 600. The charging cable 120 is, for example, rolled up when the charging station

100 is retracted into the cavity 601. Alternatively, the charging cable 120 may be wound spirally or comparable to the loops of a fire hose and thus rever ^¬ sibel be changed in length.

In FIGS. 1A and 1B, the charging station 100 and the container 200 are located in the same underground cavity 600. Depending on the spatial conditions, however, the charging station 100 and the container 200 may also be in separate cavities

are located. For example. It would be conceivable that the charging station 10 as indicated in Figure 2 adjacent to a building 50 with an outer wall 51, so that the cavity 601, in which the charging station 100 is retractable, may be provided in or behind the wall 51 of the building 50 and, for example, a room of

Building 50 is. That is, in contrast to Figures 1A and 1B, the movement of the charging station 100 is not in the vertical, but, as symbolized by the arrow P, in the horizontal direction. To move the charging station 100 in and out of the Cavity 601, a device 700 is provided which can move the charging station 100 in the horizontal direction. The device 700 is also actuated here by the control unit 500 and can, for example, operate in the manner of an electrically, hydraulically or pneumatically driven lifting platform.

The charging station is shown in FIG. 2 once with dashed lines outside the cavity 601 and once with

represented by solid line in the cavity 601, wherein the dashed representation corresponds to the state of the charging station 10, in which the electric vehicle 20 is to be charged.

The container 200, in the figure 2 without the

Electronic assembly and other details shown only symbolically, is located in the case shown here

In particular, the cavity 602 in which the container 200 is housed immediately adjacent to the cavity 601 of the charging station 100, i. the

Cavities 601, 602 also form two regions of a common cavity 600 here.

The container 200 may, however, be arranged in another embodiment also at a different location. For example. it would be conceivable, the container 200 in a basement room of the building 50 or as in the figure 1 under the footprint

accommodate, i. the cavities 601, 602 would be arranged spatially separated from each other.

In a further development of this imple mentation form, the wall 51 is not the wall of a building, but a freestanding wall such as a visual or sound insulation. In the idle state, therefore, the charging station is not located in a walled enclosure, as in the previous embodiments.

closed space 601, but in an open to at least one side space 601 behind the screen.

For the case shown in Figure 2 a in a

Building 50 built-in charging station, it is conceivable that at least a part of the surface of the container 200 to

Cooling purposes of the container or the electronics located in the container at the same time as wall or floor heating o.ä. acts. One possible embodiment is shown in FIG. 2, wherein the housing 50 has two spaces 52, 53 separated from a wall 54. The container 200 and the charging column 100 in the idle state and the other components of the charging station 10 are located in the first space 52. The container 200 is as described in connection with the figure 1 designed so that heat-emitting elements, i. in particular the electrical and electronic components, transmit their heat to the container wall 201. This can also be achieved here by heat conduction, for example. With the aid of thermal bridges (not shown) in the form of cooling plates, which the heat-emitting elements 400 with the

Connecting container wall 201. On the other hand, this can be achieved by heat convection, for example by means of air or water cooling in the container (not shown), wherein the respective coolant in turn transfers the heat absorbed to the container wall 201 and so on the wall 54.

In a further embodiment, which is indicated schematically in FIG. 3, the charging station 10 is located in a closed environment, for example in a building such as a parking garage, so that the charging station 10 is covered by a ceiling 60. In this situation, it is conceivable that the cavity 601 for sinking the charging station 100 is not provided in the ground as in FIG. 1, but in the ceiling 60. The charging station 100 is therefore lowered in this case for charging an electric vehicle 20 on the footprint 300 from the ceiling 60.

In the embodiments described above, the movement of the charging station is in each case a rectilinear movement or a translation. For example. For the case illustrated in FIG. 3, in which the cavity 601 is provided in the ceiling 60, it may be possible that the thickness of the ceiling 60 is insufficient to completely fill the charging column 100 to sink in there, since the charging station 100 along the

Longitudinal axis may be greater or only slightly smaller than the thickness of the ceiling 60. This case is shown in FIG. To solve the above problem, the device 700 with which the

Charging column in and out of the cavity 601 can be brought, not designed as a lifting or displacement device, but as a folding device. With the folding device 700, the charging column 100 is hinged about an axis 701 in and out of the cavity 601. The remaining components of

Charging station, for example, the container 200 and the charging cable 120 are not shown in the figure 3 for reasons of clarity or only hinted. For example. can the

Containers are located in the ground below the charging station 10.

Alternatively, the container above the charging station 10 may be housed in the ceiling 60. This depends on the spatial conditions. The illustration with dashed lines here corresponds to the idle state in which the charging station 100 is folded into the cavity 601. The arrow P also symbolizes the here

Direction of movement of the charging station 100. Of course, the folding device 700 also in place of

Lifting device 700 can be used in the figure 1. The type of device 700 depends essentially on the spatial conditions in the vicinity of the cavity 601 for the

Charging station off.

For all embodiments explained above, the cavity 601 has an opening 603, through which the charging column 100 can be brought into and out of the cavity 601.

Ideally, the opening 603 in the idle state, that is, when the charging station 100 is in the cavity 601, closed by a cover 604. Once the charging station 100 is to be extended out of the cavity 601, the first Cover 604 automatically removed. The cover 604 may be, for example, a flap or a sliding element.

A combination of those shown in the figures

Of course, forms of execution are possible. For example. For example, as indicated in FIG. 2, the cavity 601 of the charging column 100 may be located in a building, while the container 200 may be located underground as in FIG. Ideally, charging station 100 and container 200 are designed as one unit and as such in the ground

retractable, i. the charging station 100 is in this embodiment in the container 200. Preferably, a sealable connection 204, for example a screw connection, is provided on the container outer wall 201 for connecting the power supply 30. Such a charging station 10 can be delivered and connected ready-made without having to intervene in the interior of the charging station 10 or the container 200 during installation.

The container 200 of the charging station 10 further has a maintenance hatch 205 on the container top. For example, the electronic assembly 400 can be lifted completely or partially out of the container 200 via this service hatch 205 without the need to disconnect electrical connection cables.

Furthermore, at least when the power electronics part is removed, the container 200 can be walked on via the service hatch 205, so that possibly necessary maintenance work can be carried out.

In principle, it is not necessary for the charging cable 120 to be carried or held by the charging station, since the charging station 100 does not have any electrical or electronic equipment electronic components needed for the actual charging process, which is why the charging column for the charging itself has no meaning. It would therefore be entirely conceivable to arrange the charging cable 120 completely independently of and separate from the charging station 100. However, it offers itself as a convenience to unify charging station 100 and charging cable 120 and an opportunity to offer to suspend the charging ^¬ cable 120 at the charging station 100 because the operator then on the same site operate the charging station via the operating device 110 and can receive the charging plug 121.
