    The invention relates to a device for delivering electrical energy, in particular for delivering electrical energy to an electrical storage device of a motor vehicle.
    Such a dispenser can be positioned, for example, next to or at a parking lot for a motor vehicle with an electrical storage device to charge the electrical storage device of the motor vehicle.
    In the context of the energy turnaround there has recently been a very rapidly growing need for parking spaces in which the electrical storage of electrically operated motor vehicles can be charged. Such parking spaces are an essential prerequisite for the comprehensive implementation of electric mobility concepts. Such parking spaces must preferably be available both in public or semi-public spaces (e.g. in multi-storey car parks, on streets, etc.) as well as in private spaces (e.g. in private garages, neighborhood garages or any other type of parking space closed to the public) in order to enable mobility with electrical Motor vehicles is possible in a manner acceptable to the user.
    Such parking spaces represent an essential aspect of the infrastructure for electric mobility.
    A very important problem in the provision of infrastructure for electromobility is, however, the high costs that arise from the provision of infrastructure.
    These costs are particularly a problem against the background that an amortization of investments in such infrastructure today is usually not possible in the foreseeable future. On the one hand, the profit margins that can be achieved with the provision of parking spaces for the electric charging of motor vehicles are so small that the high investment costs are already difficult to recoup anyway. On the other hand, this is further exacerbated by the fact that only a few electrically powered motor vehicles are currently on the road. This normally results in very high fluctuations in the need for parking spaces with the possibility of electrically charging motor vehicles. In particular, it is very difficult for larger numbers of parking spaces to ensure constant and permanently high occupancy.
    Another very important problem around the charging of electrically operated motor vehicles in the context of mobility concepts is the control and communication of the individual components relevant to the charging process with one another. This is particularly relevant for the individual billing of charging processes, which is often a major problem. Electrical energy is provided via the power grid and is usually billed by the power grid operator using electricity meters. The offering of charging options for electrically operated motor vehicles ultimately represents a resale of electrical energy by the person to whose electricity meter the charging option is connected. The owner of the electricity meter therefore requires very precise consumption data, which makes it possible to quantify the electrical energy transmitted to the electric motor vehicle and, from the operator's point of view, the possibility of charging.
    In addition, a secure access to the person who is responsible for the electrically operated motor vehicle that has been charged is necessary in order to carry out a billing of a charging process of a motor vehicle. Together (the exact knowledge of consumption data, as well as the possibility of billing with the person responsible for the motor vehicle) are basic requirements for a successful business with charging options for electrically operated motor vehicles.
    Based on this, it is an object of the present invention to disclose a device for delivering electrical energy, a charging station set up for a motor vehicle and a method for charging a motor vehicle. The dispensing device, the charging station and the method at least partially solve the problems described or alleviate these problems.
    [0010] These objects are achieved with a dispensing device, a charging station and a method according to the independent claims. Further preferred exemplary embodiments of the invention are described in the dependent claims and are explained and supplemented in detail in the description. It should be pointed out that the dependent claims and the description (and in particular the description of the figures) only show preferred exemplary embodiments, to which the invention is not restricted.
    The invention relates to a device for delivering electrical energy to an electrical storage device of a vehicle, comprising a clutch for connecting the delivery device to an adapter port of a power distribution rail, a delivery connection for a delivery line for delivering electrical energy to the motor vehicle, the clutch and the output connection are arranged on or in a common housing, and wherein in the housing an energy meter and a control device with a network interface are arranged, which are configured to count the energy that is output to the motor vehicle via the output connection and energy output data via the Communicate network interface to a data processing system.
    The dispenser represents a very important part of the charging infrastructure for charging electrically operated motor vehicles for use in electromobility concepts. The dispenser combines all the logic (in particular circuit technology) that must be present at the charging station itself or in the vicinity of the motor vehicle to be charged to enable secure, individual billing of charging processes.
    [0013] On the one hand, this includes components which enable identification of the person who is responsible for the respective charging process (usually the motor vehicle operator). On the other hand, this includes components that enable an accurate detection of the energy delivered. This also includes the provision of sufficient security against manipulation. This includes (in preferred embodiment variants) above all a targeted possibility of activating and deactivating the delivery of electrical energy. The components described for the functions described include in particular an energy meter, which can be designed, for example, as an electricity meter. The output voltage with which the output device delivers or provides the electrical current is then preferably either fixed or this output voltage is also measured in order to determine the amount of electrical energy actually output. The components described further comprise a control device which monitors the electrical energy output and a network interface via which instructions can be given to the control unit and via which the control unit can communicate information about the energy output (energy output data) to a central data processing system. Other components can be implemented in the dispenser. In a simplest embodiment, however, they are not absolutely necessary to ensure the basic function of the dispensing device. With the components described here, the functions described can already be implemented in a minimal variant of the dispensing device described. The further components necessary for the functionality can be implemented, for example, in the (central) data processing system.
    Electrical energy is provided in the form of electrical current, which is available with a certain voltage. The billing of the use of a dispensing device described is usually done in conventional concepts in relation to the actually delivered electrical energy. Of course, other billing models are also conceivable, in which, for example, a time-controlled billing takes place, where the time is billed that a motor vehicle is charged at a charging station with a delivery device described. Ultimately, however, electrical energy is the most widespread variable on the basis of which the use of a charging station is billed.
    The electrical memory, which can be loaded with the described dispenser, or to which electrical energy can be dispensed with the described dispenser, is usually an accumulator. The designation of the electrical storage device as “electrical” is not to be seen to the extent that the electrical energy absorbed by the storage device must actually still exist in electrical form in the storage device. In an accumulator (for example in a widespread lithium ion accumulator or a lead acid accumulator), the electrical energy is also stored in chemical form and not in electrical form itself when it is stored. For the classification of the electrical storage as "electrical" it is rather crucial that, from the perspective of external storage components, the storage behaves as if it were storing electrical energy. During the charging process, electrical energy is delivered into the storage. The stored electrical energy can then be used. Losses usually occur as a result of the storage of electrical energy in the storage and the subsequent use / removal of this electrical energy, but this does not conflict with the definition of the electrical storage here. Of course, other types of energy storage in an electrical storage are also possible. For example in the form of kinetic energy (gyro storage) or in the form of direct electrical storage (in a capacitor) etc.
    The vehicle is in particular a conventional motor vehicle and particularly preferably a passenger vehicle (car). However, the dispenser can also be used for any other type of vehicle that can be operated with electrical energy (for example boats, planes, trucks, etc.). A special focus should also be placed on two-wheelers (for example motorbikes with electric drives or bicycles, mopeds etc.). Such two-wheelers are also vehicles for which the dispensing devices described here and the charging stations set up with them can be used.
    It is essential for the dispenser described that it is arranged directly on a power distribution rail. A power distribution rail is a special component for conducting electrical energy. A power distribution rail is particularly different from a power cable. A power distribution rail is designed to be rigid. This means that bending and deformation of a power distribution rail can occur (due to exceptionally high mechanical loads), but is not intended for use and in particular for the assembly and installation of a power distribution rail. Unlike power cables, power distribution rails are not pulled, but plugged together from various power distribution rail components in order to ensure electrical supply to a consumer (for example the dispensing device described).
    In a current distribution rail isolated from each other individual electrical conductors side by side, which form individual electrical poles. Plate-shaped electrical conductors are preferably used in current distribution rails. Between such plate-shaped electrical conductors there are insulation layers which isolate the individual conductors (the individual poles) from one another. Current distribution rails which are suitable for the transmission of three-phase currents (three-phase alternating currents) are preferred for the dispensing device described. Such electrical power distribution rails have at least three poles and, in the usual design variants, four poles, three of these four poles being used to conduct the (alternating) phases of the electrical current and a fourth pole forming the so-called zero, via which the electrical conductors are connected in a star connection on the network side a compensating current can be dissipated. Such a busbar usually has a ground line as the fifth conductor. In design variants of busbars, it is possible for the grounding line to be formed by a metallic housing of the power distribution rail.
    The power distribution rail for which the dispenser is provided here is preferably suitable for the transmission of very large amounts of electrical energy (or electrical power). It is preferred that the power distribution rail is suitable for conducting currents above 400 amperes with voltages in the low-voltage range up to 1000 V. The use of power distribution rails with transferable currents of up to 6300 amps can be implemented without any problems. Higher currents are also conceivable. Such power rails can be used to transmit electrical power in the megawatt range.
    A power distribution rail is (as already described) usually composed of individual power distribution rail components. Individual busbar components can be, for example, straight pieces for bridging longer distances, angle pieces for angling or changing the direction of the power distribution rail or connecting pieces for connecting several longer distances.
    Adapter ports are preferably provided on such a power distribution rail. Such adapter ports can be provided at the ends of power distribution rail components in the area of connecting pieces. Such adapter ports can also be provided on longer power distribution rail components in areas between the ends, for example as laterally accessible access points at which the individual conductors (poles) within the power distribution rail can be accessed in an electrically conductive manner. Such access points include, for example, interruptions in a housing of a power distribution rail, to which the conductors (poles) can be accessed and which can be closed, for example, by flaps if no delivery device is connected to an adapter port.
    The dispenser described has a coupling which can be connected directly to an adapter port of a power distribution rail. The coupling is adapted to the design of adapter ports on power distribution rails.
    The delivery device described also has a delivery connection for a delivery line for delivering electrical energy to the vehicle. It is usually the case that a vehicle is not exactly positioned relative to the dispensing device, for example because the vehicle was manually parked near the dispensing device. In this constellation, a flexible line is required on the (imaginary) last meter from the dispensing device to a corresponding connection for connecting a dispensing line to the motor vehicle. For this reason, the delivery line is flexible, at least in sections. The delivery line is particularly preferably designed at least in sections as a flexible cable. The output line must therefore be clearly distinguished from the power distribution rail. The delivery connection can preferably be a socket for a charging cable, this charging cable forming the delivery line and this charging cable being able to be inserted into the delivery connection by the owner / operator of the vehicle to be charged, for example. The delivery connection can also be a connection for a delivery line permanently installed at least in sections, to which in turn a socket (or a connecting plug) for a charging cable can be connected, which can be plugged in there by the owner / operator of the vehicle. However, this socket is a passive component, which has no control function, switching function or control function with regard to the delivery of electrical energy.
    Particularly preferably, there is also a locking mechanism at the dispensing connection, with which a connector of a dispensing line can be locked and unlocked. The locking mechanism can preferably be actively locked and unlocked by a control device of the dispensing device and / or by a data processing system with which the dispensing device communicates. The locking mechanism can particularly preferably be used to unlock the connecting plug to a delivery line after locking during charging so that it does not uselessly block the delivery connection after the end of the energy delivery process for an unreasonably long period of time.
    For the dispensing device described here, it is essential that the power supply of the dispensing device with the rigid power distribution rail takes place on the network side (on the side of the dispensing device on which the current enters the dispensing device). On the delivery side (on the side on which the motor vehicle to be supplied with electrical energy is arranged or connected to the delivery device), the energy conduction is usually also carried out using a (flexible) line.
    By coupling the dispenser to a power distribution rail, a very inexpensive, simple and safe installation of the dispenser is possible. The cable routing for the provision of charging stations for electrically operated vehicles can be considerably simplified with the dispensing device described. Another important aspect is that the (easily possible) pre-installation of power distribution rails creates the possibility of installing dispensing devices that are described very simply later. The dispensing devices do not yet have to be installed if the power distribution rail is already being placed in the vicinity of parking spaces which are later to be used as a charging station for the electrical charging of motor vehicles. This alleviates in a very efficient way the described problem of the initial investment, which regularly arises when the charging infrastructure is provided.
    Through the direct connection of the dispenser to the power distribution rail, it is also possible to provide very large electrical outputs for fast charging of vehicles. In order to ensure such services with a conventional power supply for dispensing devices via customary flexible lines, considerable effort is required when pulling these lines. This effort can be significantly reduced by the dispenser described here.
    The dispenser described here in particular also has a housing. It should be clarified here that both the coupling for connecting the dispensing device to the adapter port of a power distribution rail and the dispensing connection for connecting a dispensing line to a motor vehicle are provided in or on the housing. On the one hand, the housing is intended to protect against manipulation of the dispensing device. On the other hand, the housing also serves to protect the user from the strong currents that flow in the dispensing device or in the power distribution rail.
    The delivery device is particularly advantageous if the coupling has at least two electrically separate current transmission elements which are set up to intervene in the adapter port and to produce electrical connections to conductors in the current distribution rail.
    In the area of an adapter port on the power distribution rail, there are preferably individual openings for each conductor (pole) in the power distribution rail. The current transmission elements extend through this opening. The current transmission elements can be designed, for example, in the form of sheets with a sufficient cross section for the transmission of the electrical currents which flow to a vehicle with the delivery device for fueling electrical energy.
    The dispensing device is also advantageous if it has at least one retaining clip which is set up to form a mechanically fixed connection between the power distribution rail and the housing when the dispensing device is connected to the adapter port of the busbar.
    [0032] A retaining clip can be attached to the intended points of application of the power distribution rail in order to firmly attach the housing there. By connecting the housing to a power distribution rail, the dispenser itself is firmly connected to the power distribution rail. The retaining clip can have a snap-in mechanism which snaps into the breakpoints provided for this purpose on the power distribution rail or on the power distribution rail. In a preferred embodiment, a retaining clip is designed such that the housing or the dispensing device can be hung on the power distribution rail. For example, the dispensing device can be attached to the power distribution rail from above with a retaining clip and then applied to the power distribution rail by a pivoting movement. During this pivoting movement, the coupling of the dispensing device is inserted into the adapter port of the power distribution rail or is connected to the adapter port of the power distribution rail.
    In addition, the dispensing device is advantageous if the at least one retaining clip has at least one hook, which is designed to engage in an undercut on the power distribution rail in order to hold the dispensing device on the power distribution rail.
    [0034] The current distribution rail is particularly preferably designed in the basic form of a double T-beam. The adapter port is preferably arranged on one of the two end legs (straps) of this double Ts. The conductors of the power distribution rail are arranged in the web of this double T-beam. The bridge is therefore much wider than with conventional mechanical double-T beams. Such a design of the power distribution rail gives the power distribution rail high mechanical stability, which is fundamentally desirable. As a result of this design, there is also an undercut on the two end legs, which is oriented toward the web and which enables hooks to be gripped by the dispensing device, which enables the adapter device to be securely connected to the power distribution rail.
    The dispensing device is also advantageous if it has a safety lock with which the at least one retaining clip can be locked in order to prevent tool-free disassembly of the dispensing device from the power distribution rail.
    The blocking area of the security lock can be realized, for example, in that the security lock comprises a special screw connection which can only be actuated with a special screwdriver and which thereby ensures that the dispensing device can be detached from the power distribution rail only with a special tool. This ensures that no end user considers manipulating the dispenser. At the same time, a very quick assembly and disassembly of the dispensing device is possible for a user who has the relevant special tool available.
    In addition, the dispenser is advantageous if the housing is designed for exclusive attachment to the power distribution rail.
    An exclusive attachment to the power distribution rail means here that the dispensing device or the housing of the dispensing device has no further connections to other components which perform a mechanical holding function. Connections that perform a mechanical holding function here do not include connections that are formed by a flexible outgoing line that leads from the dispensing device and is then guided, for example, along a wall in order to lead to a socket arranged outside the dispensing device, on which, for example a charging cable of a motor vehicle can be connected. However, it is particularly preferred that such connections also do not exist, but rather that the charging station is actually only connected to the power distribution rail when no charging cable (no output line) is connected to the output connection. Then the dispenser can be easily assembled and disassembled.
    If there are a large number of adapter ports on a power distribution rail, but only fewer dispensing devices are available than adapter ports, then a user (for example an operator of the charging station, for example a car park operator) can connect dispensing devices, for example, very quickly to other adapter ports. In this way, parking of motor vehicles can often be avoided in order to move a motor vehicle to a charging station. Rather, it is possible for the charging station to move toward the motor vehicle.
    [0040] The delivery device is also advantageous if the network interface is set up to send data via at least one current transmission element.
    Such network communication can take place, for example, with components which enable the management of network communication via power networks. The data transmission preferably takes place over two conductors, namely over phase in the current distribution rail and another existing conductor of the current distribution notes (further phase or neutral conductor).
    Such components are known for example for home network user operation. Such network communication via the power transmission elements makes it possible to dispense with additional cabling for network communication (for example CAT cables which run parallel to the power distribution rail). In particular, it will also be possible to dispense with wireless network communication from the delivery device to further components (for example to a router for connection to the Internet). This fundamentally increases the security against manipulation of the network communication with the delivery device described.
    Of course, it is also possible in the delivery device described to provide alternative network interfaces, such as, for example, the already indicated wireless network communication interface (for example via WLAN) or else network communication via an additional network cable routed parallel to the power distribution rail, with the term less one here spatial parallel arrangement rather than a parallel arrangement in the sense that all dispensing devices are connected to a network (in particular indirectly also to the Internet) both from the power distribution rail with electrical energy and then via the network cable or via several (different) network cables.
    In further embodiment variants, it is also possible for a (separate) data cable to be provided in the power distribution rail for the network communication of the dispensing device with a data processing system. The coupling on the dispensing device and the adapter port on the power distribution rail are then preferably also designed such that when the dispensing device is coupled to the power distribution rail (automatically) a data-conducting connection between the dispensing device and the data cable is also formed in the power distribution rail. In design variants, it is also possible that such a connection must be established manually, for example in which the dispensing device has a network plug which can be inserted into a network socket on the adapter port of the power distribution rail. A network connection is hereby preferably established and the delivery device is then coupled to the adapter port. The delivery device preferably hides the network connection in order to protect this network connection from manipulation. Alternatively, it is also possible for the network socket to be arranged on the dispensing device and for a network plug to exist on the adapter port of the power distribution rail.
    The dispensing device is also advantageous if it has at least one electrical switch for controlling the dispensing of electrical energy at the dispensing connection.
    Such a switch is preferably in the form of a relay, in particular a high-performance relay. Such a switch makes it possible to specifically activate and deactivate the provision of electrical energy at the discharge connection.
    The dispensing device is furthermore advantageous if the control device is set up to control the electrical switch as a function of control data which the control device receives via the network interface.
    Control data are, for example, data which trigger activation of an electrical switch for providing electrical energy at an output connection or data which trigger deactivation of an electrical switch for ending the supply of electrical energy at an output connection.
    Control data can in particular also be data which effect a reservation of the charging station. Control data can be used, for example, to prevent the charging station from being seized or blocked by other users (users other than the user who reserved the charging station).
    [0050] The dispensing device is also advantageous if it has a display device for the visual and / or acoustic display of information for a user of the dispensing device.
    A display device is particularly preferably a display on which the user is shown information about the charging status (energy is provided or energy is not provided). Such a display also makes it possible to provide further information, for example information about the amount of electrical energy delivered, remaining charging time, information about subsequent charging station reservations, etc.
    However, the display device can also be made simpler, for example in the form of a lamp or a turn signal lamp, which, for example, lights up red when the dispensing device is reserved, blue when the dispensing device is available and green when the dispensing device is currently being used for a charging process. Combinations of different concepts of display devices are possible.
    A further special embodiment variant of the dispensing device described is to be briefly described here. It is also preferred if the dispensing device is provided for the simultaneous charging of several vehicles. For this purpose, the dispensing device preferably has a plurality of dispensing connections, for example two dispensing connections. Such dispensing devices can, for example, be arranged in such a way that they can be reached from two directly adjacent parking spaces. Such dispensing devices particularly preferably have only one coupling for coupling to a power distribution rail and also only one housing. However, the other structure of the dispenser is designed twice, so that the dispenser can ultimately be operated separately for each of the parking spaces to be supplied or for each vehicle in one of these parking spaces. Such dispensing devices are particularly preferred, for example, for the provision of electrical energy for two-wheelers, because two-wheelers normally do not take up so much space that long discharge lines would be necessary if several two-wheelers were loaded with only one dispensing device.
    Here, a charging station for charging an electrical storage device in a motor vehicle, having a described device for delivering electrical energy, is also to be described.
    [0055] The charging station can be any parking space for a vehicle, in particular for a motor vehicle. The charging station is particularly preferably arranged in a parking garage. In a multi-storey car park, pre-equipments for attaching the dispensing devices described can be implemented with little effort and, above all, at low cost, using the power distribution rails. Subsequently, it is possible to implement additional parking spaces with charging stations for electrically described motor vehicles at a low cost.
    The particular advantages and design features described for the dispenser described can be applied and transferred in an analogous manner to the charging stations described. The same applies to the special advantages and features of the charging station described below, which are applicable and transferable to the dispensing device.
    In a particularly preferred embodiment of the charging station in a parking garage, the power distribution rail for connecting the dispensing device is arranged in such a way that a socket arranged directly on the dispensing device and a display device (for example a display) optionally arranged on the dispensing device for a user directly in view lie. This is realized, for example, when the power distribution rail and thus also the dispensing devices are arranged at a height of approximately 1.30 m on an end wall (or rear wall) at the end of a row of parking spaces.
    In a further preferred embodiment variant of charging stations in a parking garage, a power distribution rail is arranged just below a parking garage ceiling at a height of, for example, 2 m above the floor of a parking garage deck. It is then possible, for example, to implement a free-hanging delivery line to which a vehicle can be connected which is permanently connected to the delivery device. It is also possible to lead a permanent line away from the dispenser to an external socket (an external connector). Such an external socket can then be arranged at a suitable height so that the motor vehicle can be connected to this socket.
    In further embodiment variants, it is also possible that the power distribution rail is not arranged on a wall (end wall or rear wall) at the end of parking spaces, but in the middle between two rows of parking spaces. In such an arrangement, two rows of parking spaces are preferably arranged directly adjacent to one another. These parking spaces in these two rows are then preferably accessible via separate lanes. The power distribution rail runs where the rows of parking spaces adjoin each other. The parking spaces of the two rows preferably adjoin one another at the end. The power distribution rail is then preferably set up to supply parking spaces in both rows or dispensing devices for parking spaces in both rows. This power distribution rail is therefore a "common" power distribution rail for two rows of parking spaces.
    The embodiment variant with a common power distribution rail for two rows of parking spaces in combination with a power distribution rail arranged just under a parking garage ceiling is particularly preferred. External sockets, which are connected to dispensing devices with permanent cables, are then preferably located on support pillars of the parking garage ceiling, which are preferably arranged at regular intervals on the border between the two rows of parking spaces. There the external sockets are easily accessible for a user. At the same time, the space required for the dispensing devices, the power distribution rail and the external sockets is small.
    In further preferred embodiments, the charging station described is provided at temporary parking spaces. With the charging station described or with the delivery device described and the supply of the delivery device described via power distribution rails, it is (very easily) possible to provide and dismantle electrical charging options for motor vehicles also for temporary parking spaces, for example at large events.
    [0062] In addition, a method for charging a vehicle is to be described here, this method comprising the following steps:<tb> a) <SEP> activating a delivery device for delivering electrical energy with a mobile terminal, an activation request being transmitted to a data processing system with the mobile terminal, and the data processing system triggering activation of the delivery device if the activation request was successful.<tb> b) <SEP> providing electrical energy to the dispenser via a power distribution rail, and<tb> c) <SEP> Delivery of electrical energy from the delivery device to the vehicle.
    The particular advantages and design features described for the dispensing device and the charging station described can be applied and transferred in an analogous manner to the described method. The same applies to the special advantageous features of the method described below, which can be transferred in an analogous manner to the dispensing device and the charging station.
    The central data processing system for the described method is preferably a central server which is connected to the dispensing devices, for example via the Internet, and on which software is operated which enables the charging station to be managed. This central server can be accessed, for example, using mobile end devices, a user who wants to use a charging station using an account on the server with which he can spontaneously book or reserve the charging station. The account is then usually also linked to information which enables the charging operations carried out to be billed to the operator of the dispensing device.
    The activation of the device (step a) for the delivery of electrical energy can in particular also take place in connection with a reservation of the delivery device, this reservation being carried out, for example, well before the start of the charging process. For example, you can reserve a charging station with a delivery device as described before you actually get to the location of the delivery device.
    The power distribution rail used for the provision of the electrical energy (step b) enables an efficient supply of the dispenser with large amounts of electrical energy. This also enables large amounts of electrical energy to be delivered to the delivery connection, so that the method described also makes it possible, in particular, to efficiently charge electrically operated motor vehicles.
    In addition, the use of a power distribution rail for supplying a plurality of dispensing devices for delivering electrical energy to electrical storage devices of motor vehicles is proposed here, the dispensing devices being connected directly to the power distribution rail.
    The particular advantages and design features described for the described dispensing device, the charging station and the described method can be applied and transferred in an analogous manner to the described use of a power distribution rail. The same applies to the special advantages and features described below in connection with the described power distribution rail, which can be applied and transferred in an analogous manner to the dispensing device, the charging station and the described method.
    In connection with the use of power distribution rails for supplying a plurality of dispensing devices, the very cost-efficient supply of dispensing devices for charging stations for charging electrically operated motor vehicles, as already indicated above, is possible in particular.
    A particular focus is to be placed on the fact that the dispensing devices are arranged or connected directly to the power distribution rail or that the power distribution rail thus directly supplies the dispensing devices with electrical energy. This means in particular that no other electrical line is arranged between the dispensing devices and the power distribution rail, in particular no flexible cable.
    The invention and the technical environment are explained in more detail below with reference to the figures. It should be noted that the figures show particularly preferred embodiment variants of the invention, to which the invention is, however, not restricted. It should be noted in particular that the figures are only schematic. This applies above all to the proportions shown in the figures.

    1 and FIG. 2 each show a current distribution rail 6. The current distribution rail has a double-T-shaped cross-sectional area 39 with a web 40 and two belt sections 41, viewed from the outside, each at the ends of the web 40 connect. Electrical conductors 15 of the power distribution rail 6 are located in the web 40. The electrical conductors 15 are insulated from one another with electrical insulation (not shown separately here) and against a housing of the current distribution rail 6 (not shown separately here). The current distribution rail 6 shown here (according to FIGS. 1 and 2) has four electrical conductors 15. Three of these electrical conductors 15 are preferably used to transmit a three-phase alternating current. The fourth of these electrical conductors 15 serves as a neutral conductor. The housing of the power distribution rail 6 (not shown separately here) serves as an earth conductor. 2 shows the adapter port 5 on the power distribution rail 6. The adapter port 5 is arranged on one of the belt sections 41 and is mechanically protected by the projecting flange 42 on the belt section 41. This adapter port 5 is used to connect a dispensing device 1, which in the illustration according to FIG. 1 is placed on the adapter port 5 of the power distribution rail 6. A coupling 4 of the adapter device 1 (shown in FIG. 3) can be connected to the adapter port 5. The adapter port 5 has plug receptacles 27 into which (current transmission elements 14 shown in FIG. 3) the coupling 4 of the delivery device 1 can engage in order to transmit current from the conductors 15 of the power distribution rail 6 to the dispensing device 1. The adapter port 5 has a cover 23 with which the adapter port 5 can be closed, so that the adapter port 5 is protected when no dispensing device 1 is placed on the adapter port 5. The cover 23 can preferably be closed with a bolt 24, which can preferably only be opened with a key or a tool.
    The dispensing device 1 shown in FIG. 1 has a housing 9 and it can be fastened to the power distribution rail 6 with retaining clips 16 if the coupling of the dispensing device 1 (shown in more detail in FIG. 3) to the adapter port 5 of the power distribution rail 6 is put on. The holding clips 16 each have hooks 17 which engage in undercuts 18 which are formed by the belt sections 41 of the power distribution rail 6. The holding clips 16 can preferably be locked with a safety lock 19. The safety lock 19 can preferably only be released with a special tool or a key. It can also be seen in FIG. 1 that the dispensing device 1 has a dispensing connection 7 for connecting a dispensing line 8 (not shown here), via which electrical energy can be provided for a vehicle. Also shown is a display device 21 (shown here as a display) with which information can be provided to a user of the dispensing device 1.
    3 shows a rear view of the dispensing device 1. Here, the coupling 4 can be seen on the housing 9 of the dispensing device 1, which cannot be seen in FIG. 1, because this coupling 4 is shown in FIG. 1 the side of the dispensing device 9 oriented toward the power distribution rail. It can be seen that the coupling 4 has current transmission elements 14 which can engage in plug receptacles of the adapter port on the current distribution rail (see FIG. 2). 3 also shows the holding clips 16, which are each arranged laterally on the housing 9 of the dispensing device 1 and which have hooks 17 and a safety lock 19. The hook 17 and the safety lock 19 have already been explained above in connection with FIG. 1.
    4 shows a housing interior 28 of the housing 9 of the dispensing device 1. In the housing interior 28, the current distribution rail 6 with its conductors 15 is shown schematically in the background in dashed lines. High-performance conductors 26 can be seen in the housing 9, which run from current transmission elements 14, which are in contact with the conductors 15, to the discharge connection 7. In the housing 9 there is an electrical switch 20, with which the provision of electrical energy at the discharge connection 7 can be activated and deactivated. In the housing 9 there is also an energy meter 10 with which electrical energy can be counted, which is output at the output connection 7. In addition, a control device 11, which controls the dispensing device 1, is also arranged in the housing 9. For this purpose, the control device 11 is connected via internal data lines 43 to the other components in the housing 9 of the dispensing device 1, namely in particular to the electrical switch 20 and the energy meter 10. The control device 11 is also connected to a network interface 12 which has a network connection 26 which has a data-conducting connection to an external, central data processing unit (for example a central control server for a large number of such dispensing devices) via the current transmission elements 14 or via the conductors 15 of the power distribution rail 6.
    5 and FIG. 6 each show examples of configurations of charging stations 22 with dispensing devices 1 described. In both figures, charging stations 22 are shown in parking spaces in a parking garage, with electrified parking spaces 38 each equipped with dispensing devices 1 (which also can be referred to as charging stations 22) and conventional parking spaces 37 exist. In the electrified parking lots 38 and the charging stations 22 there are motor vehicles 3 with electrical storage devices 2, which are connected via delivery lines 8 to delivery connections 7 of the delivery devices 1. The dispensing devices 1 are each arranged at the end of the parking spaces on a rear wall 44 of the parking garage. To supply the dispensing devices 1 with electrical energy, a power distribution rail 6 runs along the parking spaces on the rear wall 44. The dispensing devices are connected to adapter ports 5 of the power distribution rail 6. Both in FIG. 5 and in FIG. 6, an adapter port 5 is shown, to which no dispensing device 1 is connected. In each case there is a conventional parking lot 37 on which an electrically operated motor vehicle 2 cannot be charged. By installing a dispensing device 1 on this adapter port 5, this conventional parking lot 37 can be upgraded or converted very quickly to an electrified parking lot 38 or to a charging station 22.
    5, the power distribution rail 6 and the dispensing devices 1 are installed at a height so that a user can easily reach the dispensing connection 7 on the dispensing device 1 and can also read a display device 21 on the dispensing device 1. This is achieved by a rail height 34 of the power distribution rail 6 between 0.80 m and 1.40 m above the floor of the parking spaces.
    6, the power distribution rail 6 and the dispensing devices 1 are installed at a height at which a user can no longer easily reach the dispensing connection 7 on the dispensing device 1. The rail height 34 of the power distribution rail 6 corresponds here, for example, more than 1.80 m above the floor of the parking spaces. The power distribution rail 6 is particularly preferably arranged just below the parking garage ceiling 34 (less than 0.30 m below the parking garage ceiling 34 or even less than 0.20 m below the parking garage ceiling 34). In this embodiment variant, it is not only the dispensing connection 7 on the dispensing device 1 that is not easily accessible to a user. A display device 21 directly on the housing of the dispensing device 1 would also not be easy to read for a user here. For this reason, the discharge line 8 is first led here from the discharge connection 7 to an (external) connector 36, to which a further section of the discharge line 8 can be connected. A user can then easily do this. The connector 36 is preferably permanently installed on the rear wall 44 of the parking spaces. A display device 21 is preferably also arranged on the rear wall 44 at a height which is easy to read by a user, so that a user can read it easily.
    7 shows a schematic illustration of various details of a system around the dispensing device 1 described, with a focus on the data communication of the various components with one another. Two dispensing devices 1 can be seen which are connected to the power distribution rail 6. It is shown that the power distribution rail 6 can be composed of different pieces. Straight pieces 29 and an angle piece 30 are shown here by way of example. Many different further types of power distribution rail pieces can exist with which an electrical supply system based on power distribution bar can be easily adapted to the prevailing spatial conditions. In the upper dispensing device 1 in FIG. 7, the interior consisting of the control device, energy meter and network interface 12 is also shown schematically, these components being shown here only by way of example. There may be many other components in the dispensing device 1, which are also explained in detail further above (for example in connection with FIG. 4). Particular attention should be drawn here to the network interface 12 in the delivery device 1, which enables the control device 11 to be connected to a central data processing unit 13 via the network interface, the power distribution rail 6, a further network adapter 31, a router 32 and an Internet connection 45 . The central data processing unit 13 is, for example, a server with which a large number of delivery stations 1 can be managed centrally. A user can make a booking of a delivery station 1 with the aim of obtaining electrical energy from the delivery station 1 using a mobile terminal device 33 which communicates with the central data processing unit 13 via a mobile radio connection 46. It should be pointed out that all of the network components shown here (mobile radio connection 46, internet connection 45, router 32, network adapter 31, etc.) are only schematic and are intended to clarify the basic functioning of the connection between dispensing device 1, central data processing 13 and mobile terminal 33.
    8 and 9 show two different, alternative design variants of current distribution rails 6, with which the dispensing devices described here can be combined. These power distribution rails 6 are alternatives to the design variant of a power distribution rail 6 according to FIGS. 1 and 2. In order to be able to be used with the design variants of power distribution rails 6 shown in FIGS. 8 and 9, described dispensing devices 1 and in particular their couplings 4 must be connected the corresponding adapter ports 5 of these design variants of power distribution rails 6 can be adapted.
    8 and 9 it can first be seen that adapter ports 5 are designed differently in these power distribution rails 6 than in the power distribution rail 6 according to FIG. 2. FIG. 8 shows a rectangular adapter port 5 which extends in a longitudinal direction of the power distribution rail 6 is compact. FIG. 9 shows an adapter port 6 which is recessed in an indentation 48 in the power distribution rail 6. This adapter port 5 is therefore particularly well protected. The (electrical) mode of operation of the adapter port 5 according to the embodiment variants in FIGS. 8 and 9 is ultimately identical to the mode of operation of the adapter port 5 in the embodiment variant according to FIGS. 1 and 2. The adapter ports 5 each enable correspondingly via plug receptacles 27 for individual current transmission elements trained coupling on the dispenser access to the electrical conductors 15 in the power distribution rail 6. Both adapter ports 5 according to FIGS. 8 and 9 can each be covered with a cover 23, which can be closed with a bolt 24 shown schematically. 1 and 2, it is provided that the dispensing device can be coupled to undercuts on the current distribution rail with the aid of hooks or retaining clips. In contrast, in the case of the power distribution rails 6 according to FIGS. 8 and 9, points of attack 27 are explicitly provided, which enable the intervention of a mechanical coupling mechanism (however made) in the dispensing device 1 in order to firmly connect the dispensing device to the power distribution rail 6. As a special feature of the embodiment variant according to FIG. 9, it is also shown that a network plug 49 is also provided on the adapter port 5, which enables a data connection from the dispensing device to a data line arranged in the power distribution rail 6 (not shown here).
