Description

[0001] Ma / pj / rh December 28, 2023 Applicant: ONgineer GmbH 32339 Espelkamp Charging station for e-scooters The invention relates to a system with at least one, in particular a plurality of, battery-operated vehicles and a station for charging and holding the vehicle according to the preamble of claim 1, as well as a method for keeping a battery-operated vehicle ready at a station. Light battery-operated vehicles (LEVs or Light Electric Vehicles) are being used to an increasing extent, especially in public spaces, particularly in large cities. This is because such vehicles enable easy progress, can be parked easily and, moreover, do not emit any pollutants during their use. Such a vehicle, to which a generic system relates, has at least one front wheel and one rear wheel. Vehicles are also known in which a pair of front wheels and / or a pair of rear wheels are provided, wherein such a pair of front wheels orRear wheels spatially rotate about the same axis of rotation. The invention relates in particular to vehicles with a small track width, for example to vehicles each having only one front wheel or only one rear wheel, or to vehicles in which a pair of front wheels and / or a pair of rear wheels is provided, wherein the wheels of the pair are only slightly spaced from each other, in particular by less than 50 cm, in particular less than 40 cm, in particular less than 30 cm. Such a vehicle preferably has a track width of less than 50 cm, wherein the track width is defined as the extension length along an axis of rotation between the ends of the at least one wheel pointing away from each other with respect to this axis of rotation, in particular of the pair of wheels provided on the axis of rotation, which is / are designed to rotate about the axis of rotation. The track width on an axis of rotation on which only one wheel is provided is thus determined by the width of theWheels are defined. Battery-powered vehicles, which are the subject of the present invention, are usually two-wheeled, but vehicles are also known in which a pair of wheels with a narrow track width are provided on a rotational axis in order to ensure greater driving stability. In particular, the present invention relates to e-scooters as battery-powered vehicles or battery-powered vehicles of the system. Two fundamental problems arise with such systems: Firstly, the battery-powered vehicles must be regularly charged. This is particularly problematic because the vehicles should, by their very nature, be as light as possible, and therefore the battery capacity is limited. Secondly, such vehicles must be able to be parked in a way that is as secure as possible against theft. Especially in systems in which a large number of vehicles are used, for example several hundred vehicles, aThe most sensible distribution of vehicles and / or the least disruptive parking of vehicles must be ensured. Conventional systems do not adequately meet these requirements. Stations known in the prior art are expensive to implement, take up considerable space, and are difficult to operate. Therefore, conventional stations are rarely used; instead, the battery-powered vehicles are charged and secured individually. This represents a significant expense for an individual owner of such a vehicle, and also represents a significant expense for the operator of vehicle fleets with a large number of vehicles, especially more than one hundred vehicles, as the vehicles must be charged individually by personnel and distributed in a targeted manner by personnel, and due to a lack of security, they are often victims of vandalism. The present invention is based on the object of providing a system or methodwith which at least one problem or at least one disadvantage that exists in generic systems or methods can be at least partially remedied. As a solution to the problem underlying the present invention, the invention proposes a system with the features according to claim 1. The system comprises a battery-operated vehicle. The vehicle has a fixing device, a battery, a charging port, and a plurality of wheels. Preferably, the vehicle has a track width of less than 50 cm. The system further comprises a station for charging and holding the vehicle. The station has a fixing device corresponding to the fixing device of the vehicle, wherein the fixing device and the fixing device are designed to correspond to one another in such a way that the vehicle is fixed to the station by the interaction of the fixing device and the fixing device in a fixing state of the system. The fixing state of theSystem describes a defined arrangement of the components of the system relative to one another. Preferably, in the fixed state, the charging port of the vehicle is connected to a charging device of the station, so that the charging device charges the vehicle via the charging port. The connection of the charging port to the charging device can generally be made via a cable or wirelessly. Preferably, the station further comprises an inductive charging device for inductively charging the battery of the vehicle in the fixed state via the charging port of the vehicle. The charging port can thus be designed to enable inductive charging of the battery, thereby ensuring wireless charging. Preferably, the charging port is electrically connected to the battery for this purpose and forms an interface via which it can receive energy from an inductive charging device. Typically, an inductive charging device has at least one, in particularseveral primary coils, and the charging connection has at least one, in particular several secondary coils. By supplying energy to the primary coil, an electromagnetic field is generated, which generates a current flow in the secondary coil, which current is conducted in the vehicle from the charging connection to the battery to charge the battery. Preferably, the fixing device and the charging device of the station are positioned in a fixed manner relative to one another. Also preferably, the fixing device and the charging connection of the vehicle are positioned in a fixed manner relative to one another. Preferably, by a fixed positioning of the fixing device and the fixing device relative to one another in the fixing state, the charging connection is thus positioned in a fixed manner relative to the charging device. Generally, in the fixing state of the system, the fixing device and the fixing device engage with one another, wherein the engagement of the fixing device and the fixing device enables the vehicle to be moved away fromthe station is prevented. The interlocking of the fixing device and the fixing mechanism thus serves, on the one hand, to securely fix the vehicle to the station in order to prevent vandalism or unauthorized use of the vehicle. In a released state of the system, however, the fixing device and the fixing mechanism are detached from one another, so that the vehicle is not fixedly positioned at the station by their interaction, but can be detached or removed from the station or is detached or removed. Preferably, the interlocking of the fixing device and the fixing mechanism in the fixed state serves to specifically position the charging connection relative to the charging device, so that it is ensured that the vehicle's battery can be charged in the fixed state. The system according to the invention thus has the particular advantage of simultaneously securing and efficiently charging the vehicle atthe station is ensured so that the vehicle is kept ready for use by a user at the station. The system according to the invention has a particularly simple construction. Preferably, one of the fixing device and the fixing means has a first fixing section designed in the manner of a movable bolt and a locking device for moving the first fixing section. Preferably, the other of the fixing device and the fixing means has a second fixing section designed as a receptacle for the first fixing section. Preferably, in the fixing state, the first fixing section is arranged in the receptacle and enclosed by the receptacle, preventing the first fixing section from being removed from the receptacle. Preferably, in the fixing state, the arrangement of the first fixing section in the second fixing section, i.e. in the receptacle, prevents the vehicle from becoming detached from the station.Preferably, the enclosing of the first fixing section in the receptacle thus involves at least partially encompassing the first fixing section, wherein the encompassing in the fixing state ensures that the first fixing section cannot be moved out of the receptacle. In one embodiment, the receptacle in the fixing state encloses the first fixing section in each of the three mutually perpendicular spatial directions on both sides. In another embodiment, the receptacle encloses the first fixing section in at least one spatial direction on only one side, wherein a further section of the fixing device and fixing unit ensures that the vehicle cannot be removed from the station in the direction pointing to the other side along the spatial direction. For example, the receptacle can be U-shaped, wherein the U is open at the bottom and, in the fixing state, the bolt within the Uis arranged, wherein in the fixed state, the vehicle rests with its underside against a section of the fixing device, so that a movement of the bolt in the fixed state downwards out of the U is impossible. Preferably, the first fixing section is movable from the fixed state by means of the locking device out of the receptacle to realize a release state of the system, in which the vehicle can be removed from the station. Due to the mobility of the bolt by means of the locking device, it can thus be determined via the position of the bolt whether the system is in the closed state or in the released state. The bolt can have a suitable shape for this purpose, for example, be designed as a cylindrical bolt or as a curved bolt. It is essential that the position of the bolt determined in the fixed state enables the bolt to be removed from the receptacle through the interaction of the fixing device and the fixing device.is prevented, whereas in the position of the bolt, which it holds in the released state, movement of the vehicle relative to the station is not prevented by the interaction of the fixing device and the fixing mechanism. In advantageous embodiments, the invention can thus provide the particular advantage of combining two simplifying measures: Firstly, a particularly simple measure for securely fixing a vehicle to a station is provided. Secondly, a particularly simple measure for charging the vehicle is provided. By combining the measures, the interaction of the fixing device and the fixing mechanism alone ensures such an alignment of the vehicle relative to the station that inductive charging is possible. The system according to the invention is particularly easy to operate by a vehicle user, since the user only has to park the vehicle at a station in such a way thatthat the locking device can move the bolt in such a way that the system, starting from the released state it initially assumes when a user parks the vehicle at the station, can assume the locking state. The interlocking of the locking device and the locking mechanism ensures both a secure locking of the vehicle to prevent vandalism or unauthorized use and also ensures the feasibility of an efficient charging process, as the vehicle is held with its charging connection directly in such a position that a charging process can take place. Due to the provision of an inductive coupling between the charging connection and the charging device, an electrically conductive connection between them is not required or can be avoided by means of appropriate electrically conductive contact, so that the very simple locking of the vehicle at the station does not involve a load on the contacts required for charging.accompanies. Preferably, the fixing device and the fixing mechanism alone and independently of the electromagnetic connection between the charging connection and the charging device required to realize a charging process ensure a defined positioning and fixing of the vehicle at the station in the fixing state. The system according to the invention thus opens up, in advantageous embodiments, new possibilities for the use of battery-operated vehicles in public spaces. Due to the simple design of the fixing device and the fixing mechanism, the station can be designed to be small, and by automatically holding the charging connection in a predefined position relative to the charging device in the fixing state of the system, a charging process can be carried out automatically, and wear and tear on system components can be reduced to a large extent. Due to the simplicity of the system, the system can be equipped with interfaces or suchThe system can be equipped with a control device so that a large number of vehicles can be easily and automatically held at stations. For example, the system's control device can be designed to detect the need for charging when a vehicle is in a locking state of the system at a station, and to automatically initiate or carry out a charging process when the need is identified. Furthermore, user authentication can be enabled via the interfaces. Furthermore, the station can optionally, depending on the user's wishes, either only lock a vehicle or also charge the vehicle. For example, different profiles can be stored in the control device so that different customer requirements can be met with a single station, which is not only ecologically sound, but also makes sense from a cost and space saving perspective. For example, some users can use the station purely forto securely fix their vehicle, while other users can also use it to charge their vehicle, so that such a station can also be used, depending on the profile used, simultaneously by a fleet operator and by private individuals with their private vehicles, if a sufficient number of charging devices and fixing devices are provided at this station, via which a sufficient number of vehicles can be securely fixed or charged at the station. In general, the invention preferably relates to a system with a station having several charging devices and several fixing devices. Each charging device is designed to correspond to a charging connection of a vehicle. Each fixing device is designed to correspond to a fixing device of a vehicle. The station can be designed to accommodate one and the same vehicle at different locations, i.e. the same vehicle can be used at severaltheir fixing devices and can be charged at a charging device corresponding to the respective fixing device. All charging devices of a station can be designed completely individually from one another or, alternatively, at least partially use a common infrastructure, for example, a common central controller and / or a common central supply connection of the station. Particularly preferably, the fixing device and the fixing device engage with one another in the fixing state such that their relative position to one another is fixed in all three spatial directions. As a result, the vehicle is held particularly reliably at the station in the fixing state. Particularly preferably, the arrangement of the first fixing section in the receptacle fixes the relative position of the first fixing section relative to the second fixing section, i.e., relative to the receptacle, in at least one spatial direction.and in particular along a further spatial direction in one direction, whereas in the other direction along this further spatial direction the relative position is determined by a further section of the fixing device and a further section of the fixing device, which are designed to correspond to one another. In the present case, the three spatial directions are meant to be the three mutually perpendicular spatial directions that span a three-dimensional space. Generally speaking, the interlocking of the fixing device and the fixing device in the fixing state preferably determines their relative position to one another at least to a position range of less than 5 cm, in particular less than 3 cm, in particular less than 2 cm, in particular less than 1 cm in all three spatial directions. Thus, in the fixing state, the fixing device and the fixing device can each differ by a maximum of 5 cm, in particularat most 3 cm, in particular at most 2 cm, in particular at most 1 cm relative to each other. Particularly preferably, by the engagement of the fixing device and the fixing means in the fixing state, their relative position to each other along at least one of the spatial directions, in particular along at least two of the spatial directions, is fixed to a position range of less than 2 cm, in particular less than 1 cm, associated with the respective spatial direction. By fixing the position of the fixing device and the fixing device relative to each other, the position of the charging device and the charging connection relative to each other can be fixed accordingly, so that by this fixing in the fixing state, charging of the battery through the interaction of the charging device and the charging connection can be ensured with a high degree of efficiency. It has proven particularly advantageous to set the position range in a specific spatial direction, over whichThe fixing device and the fixing mechanism, which are movable relative to one another in the fixed state, are to be designed to be smaller than in at least one other spatial direction, in particular than in both other spatial directions. This makes it as easy as possible for a user to park and connect the vehicle to the station, and at the same time, charging with a high degree of efficiency can be ensured. It has proven particularly advantageous to fix their relative position to one another by the interlocking of the fixing device and the fixing mechanism such that they are movable relative to one another along a first spatial direction over at least 1 cm, in particular at least 1.5 cm, in particular at least 2 cm, whereas their relative position with respect to a second spatial direction is fixed to a position range of less than 2 cm, in particular less than 1.5 cm, in particular less than 1 cm, in particular less than 0.7 cm. ThisIn the first spatial direction, a certain degree of variability and thus easy connection of the vehicle to the station can be ensured, whereas with respect to the second spatial direction, the most precise possible fixation of the vehicle to the station and thus also of the charging connection relative to the charging device can be ensured. Particularly preferably, the charging device has a primary coil and the charging connection has a secondary coil, each of which is assigned a coil axis, wherein the second spatial direction has an angle of less than 30°, in particular an angle of less than 20° to the coil axes of the primary and secondary coils, wherein in particular the second spatial direction runs parallel to the coil axis of the secondary coil and the other spatial directions are perpendicular to this second spatial direction. Thus, by fixing with respect to the second spatial direction, a very close arrangement of the primary and secondary coils can be enabled, whichhigh efficiency in charging the battery. Preferably, the properties explained above for the second spatial direction generally apply to the specific spatial direction explained above. In particular, the invention is dedicated to the problem of solving an inappropriate spatial distribution of vehicles. In practice, it has been shown that common systems, during their operating time, are often in states of asymmetrical, arbitrary, or inappropriate spatial distribution of vehicles, which, among other things, leads to few or no vehicles being found at individual stations. For example, in heavily frequented locations, there is often not a sufficient number of vehicles available. For example, vehicles are often parked so far away from stations that charging and thus continued use of the vehicles is only possible with great effort. Such problems can affect the generalUser satisfaction of these systems can be severely negatively impacted, resulting in low sales. Furthermore, it often happens that vehicles, especially large accumulations of vehicles, are parked in such a way that they cause obstructions on footpaths and cycle paths. To solve the aforementioned problem of the uneven spatial distribution of vehicles, the invention proposes an embodiment of the system according to the invention, which is characterized in that the vehicle comprises a drive, in particular in the form of an electric motor, which is designed to drive the vehicle, and a communication interface, in particular a wireless communication interface such as NFC, Bluetooth, NB-IoT, Wi-Fi, ZigBee or other radio interfaces. In an enabled state of the vehicle, the drive can be controlled, and in a locked state of the vehicle, the control of the drive is prevented, in particular theThe power supply to the drive is interrupted in the locked state. The vehicle can have a locking device that can be switched into a locked state and alternatively into a released state, whereby the vehicle can be switched into its locked state or released state. Preferably, a change between the locked state and the released state of the vehicle can occur both in the released state and in the fixed state. The system, in particular the vehicle and / or the station and / or a central unit connected to the vehicle and / or the station, comprises a computing device, in particular a microcontroller and / or a processor unit, and a memory, in particular a RAM memory and / or a non-volatile memory such as an HDD. The central unit with computing device can be the central computing unit explained here in connection with embodiments. The computing device is designed to communicate with the communication interface of the vehicle, andThe computing device is further configured to store a predefined value in a memory area of ​​the memory upon detection of a transition of the vehicle from the locking state to a ready-to-drive state in which it holds the release state and the release state, and to convert this predefined value into a first modified value upon a transition of the vehicle from the ready-to-drive state to the locked state and / or to convert the predefined value into a second modified value upon a transition of the vehicle from the ready-to-drive state to a state in which it holds the locked state and, in addition, the locking state. The system comprises a plurality of further vehicles. The further vehicles can in particular each also have the features described herein for a vehicle. In particular, a central unit with a computing device can be provided, which is connected via the communication interface of each respective vehicle to therespective vehicle as explained here. This embodiment allows different state transitions in the system to be detected differently and mapped in the corresponding modified values, thereby allowing a flexible response to various changing parameters of the system. In particular, the detection of a state can comprise the determination via sensors, such as infrared sensors, pressure sensors or buttons by the computing device that the vehicle is in a certain state, such as the power supply to the battery is interrupted or the vehicle is fixed in a station. In one embodiment, the computing device is designed to receive user data for using the vehicle, such as a user account in a cloud, account data or bank data. Furthermore, in one embodiment, the computing device is designed to assign the first modified value in the memory area to the receivedUser data by storing first credit information associated with the user data in the memory. In addition, in one embodiment, the computing device is designed to assign the second modified value in the memory area to the received user data by storing second credit information associated with the user data in the memory. The computing device is designed to, upon detection of a transition of the vehicle from the ready-to-drive state to the locked state, assign credit information to the user account in the memory depending on the first credit information, wherein the dependency of the credit information on the first credit information is determined by a first dependency function. Furthermore, the computing device is designed to, upon detection of a transition of the vehicle from the ready-to-drive state to the state in which it has the fixed state and the locked state, assign credit information depending onto assign the second credit information to the user account in the memory, wherein the dependency of the credit information on the second credit information is determined by a second dependency function. Such a preferred embodiment allows, by recognizing the various states of the vehicle and by the corresponding modification of the credit information by the dependency functions, to influence the credit information and to reactively change the credit information with regard to the various cases of state transitions. Thus, for example, by coordinating the two dependency functions, it can be achieved that, for example, one of the state transitions results in positive credit information, whereby any users of the vehicle preferentially carry out this state transition with the vehicle. The introduction of the dependency functions thus makes it possible to modify the credit information not only in dependencies of thestate transitions, but also to modify the credit information upon a specific state transition. Preferably, each of the dependency functions has a parameter that depends on a location of the vehicle on Earth (e.g., identified by GPS coordinates), and a parameter that depends on time. To define the dependency on time, time can be defined by a date and a time on the respective date. Preferably, each dependency function therefore has a dependency on the location of the vehicle and on time. As a result, location- and time-dependent specifications for an appropriate spatial distribution of the vehicles can be particularly well taken into account. In a further embodiment, the system comprises several stations, wherein the vehicle can be brought into the fixation state at each station. In one embodiment, the computing device is designed toa first radius around a first geoposition is defined, as the target parking location, wherein the first radius is defined by a first radius definition. Preferably, the first radius definition is defined, in particular by the computing device, as a function of a first predefined density of vehicles in a predefined radius of the geoposition. Particularly preferably, the first dependency function contains, as a parameter influencing a value of the first dependency function, the query as to whether a detection of the transition from the ready-to-drive state to the locked state has occurred at the target parking location. Furthermore, particularly preferably, the first radius definition is defined as a function of time data, position data, weather data and / or the computing device is designed to define the first radius definition as a function of user input data received at the computing device. Geoposition essentially means a distance defined by longitude andLatitude-defined position, which can be determined or specified, for example, by GPS. This embodiment has surprisingly proven particularly useful for achieving a desired spatial distribution of vehicles by having the system reactively respond to external influences and / or defined influences and offering a financial incentive, for example, by credit payment, to park vehicles at target stations and / or target parking locations. The inventors have recognized that by defining a target parking location by a radius, which itself is defined by a radius definition that depends on the physical properties of the system, for example, the density of vehicles, the availability of fixing devices at the station and / or other data entered by a user, the credit information can be adjusted particularly specifically to achieve a desired spatial distribution of the vehicles. In a furtherIn a preferred embodiment, the computing device is designed to define the station or one of the several stations located within a second radius around a second geoposition as the target station, wherein the second radius is defined by a second radius definition. Preferably, the second radius definition is defined, in particular by the computing device, as a function of a second predefined density of vehicles in a predefined radius of the second geoposition. Furthermore, the second dependency function preferably contains, as a parameter influencing a value of the second dependency function, the query as to whether a detection of the transition from the ready-to-drive state to the state in which it has the fixing state and the blocking state has occurred at the station defined as the target station and / or the second dependency function contains, as a parameter influencing a value of the second dependency function, the querycontains whether a detection of the transition from the ready-to-drive state to the locked state has occurred in the predefined second radius around the target station. Preferably, the second dependency function depends on a detection of an availability of the target station, for example a full occupancy of the target station and / or the detection of a defect in the target station. Furthermore, the second radius definition is preferably determined as a function of time data, position data, weather data and / or the computing device is designed to determine the first radius definition as a function of user input data received at the computing device. Generally, the first dependency function and the second dependency function, and in particular the first radius definition and the second radius definition, differ in their functional dependencies. Furthermore, the aforementioned problem of the uneven spatial distribution of vehicles is solved by aThe invention provides a method for operating a system according to the invention, wherein the system comprises a battery-operated vehicle, in particular an e-scooter, which has a fixing device, a battery, a charging port, a plurality of wheels, and a track width of less than 50 cm, as well as a station for charging and holding the vehicle. The station comprises a fixing device corresponding to the fixing device for fixing the vehicle in a fixing state of the system, and a charging device. In the fixing state, the fixing device and the fixing device engage with each other, preventing removal of the vehicle from the station. In a release state of the system, the fixing device and the fixing device do not engage with each other, so that the vehicle can be removed from the station. The vehicle further comprises a drive and a communication interface, in particular a wireless communication interface such as NFC.Bluetooth, NB-IoT, Wi-Fi, ZigBee or other radio interfaces, wherein in a release state of the vehicle the drive can be controlled and in a locked state of the vehicle the control of the drive is prevented. The method is characterized in that it is monitored whether the vehicle transitions from the fixation state to a ready-to-drive state in which it holds the release state and the release state, and upon detection of such a transition a predefined value is stored, and then it is monitored whether the vehicle, starting from the ready-to-drive state, transitions only to the locked state without also transitioning to the fixation state, or whether it transitions from the ready-to-drive state to both the locked state and the fixation state. Upon detection of a transition of the vehicle from the ready-to-drive state to only the locked state, the predefined value is converted into a first modified value and / or the predefined value isTransition of the vehicle from the ready-to-drive state to the locked state and the locking state is converted into a second modified value, wherein the system comprises a plurality of further vehicles which are monitored with regard to their state and location. In one embodiment, the first or second locking section provided by the locking device is provided at a front of the vehicle. In general, it should be noted at this point that either the vehicle forms the first and the station the second locking section, or the station forms the first and the vehicle the second locking section. By providing the locking section formed by the locking device and thus by the vehicle at the front of the vehicle, this locking section can be used in a particularly user-friendly manner to implement the locking state. This is because a user can, by moving the vehicle in the direction of travel,in a simple and visually comprehensible manner, the vehicle can be arranged with the fixing section provided on the vehicle on the fixing section formed by the station. Furthermore, the fixing section can be arranged on the vehicle in a particularly advantageous spatial manner. Naturally, the front of the vehicle is understood to be the side with which the vehicle faces forward when driving straight ahead as intended, i.e., the side that is visible when viewing the vehicle purely from the front. In one embodiment, the vehicle has at least one front wheel and at least one rear wheel, as well as a basic structure. The basic structure comprises a frame with a steering tube, a handlebar, and a handlebar. The front wheel and the rear wheel are connected to one another by means of the frame. The handlebar is rotatably mounted in the steering tube. The handlebar is firmly connected to the handlebar. On the frame or on the handlebarthe axles are provided, about which the wheels are each rotatably mounted. Generally preferably, that of the first and second fixing sections which the fixing device and thus the vehicle has, is designed as a projection protruding from the basic structure. The fixing section thus forms a projection formed from the basic structure. As a result, the fixing section can be arranged in a particularly robust and easily accessible manner. Particularly preferably, the basic structure is made at least partially from a metal, wherein the said fixing section which the fixing device has is made of metal. Generally preferably, the fixing section formed by the fixing device is arranged on the handlebar or the steering tube of the vehicle. The arrangement on the steering tube has proven to be particularly advantageous, since the steering tube is rigidly connected to the frame of the basic structure and thus ensures a particularly rigid fixation of the vehicle to theStation is made possible by means of said fixing section. In general, as explained, the vehicle preferably has at least one front wheel, at least one rear wheel, and a basic structure comprising a frame with a steering tube, a handlebar, and a handlebar, wherein the first and second fixing section formed by the fixing device is arranged on the handlebar or the steering tube of the vehicle. Furthermore, the charging port is preferably also arranged on the handlebar or the steering tube. In one embodiment, the charging port is spaced from the fixing section provided by the fixing device by less than 20 cm, in particular by less than 15 cm, in particular by less than 10 cm. As a result, by fixing said fixing section relative to the fixing section encompassed by the station, an alignment of the charging port relative to the charging device can be made possible with particularly accurate positioning. GeneralPreferably, the charging port is provided on the same side of the vehicle as the fixing section provided by the fixing device. This is particularly advantageous for aligning the charging port relative to the charging device by means of said fixing section. In one embodiment, the second fixing section is designed in the manner of a ring or bracket, which encloses the first fixing section at least partially around an axis. In the case of a ring, this axis is the ring axis; in the case of a bracket, this axis is the axis around which the bracket partially extends. Preferably, the bracket extends over at least 180°, in particular at least 200°, in particular at least 230° around the axis. In this case, the ring or bracket preferably forms the aforementioned receptacle by at least partially enclosing the axis. The inventors have recognized that the design of the second fixing section in the manner of a ring or bracketis particularly easy to achieve and that by inserting the bolt into a ring or bracket, and thus along the described axis, so that the bolt axis extends at least substantially parallel to the said axis, a reliable fixation of a vehicle to a station in the fixation state can be achieved particularly easily. The axis particularly preferably runs horizontally. At this point, it should be noted that the vertical or vertical direction defines the direction with respect to which the wheels of the vehicle form the vertical underside of the vehicle, with which the vehicle rolls on a road as intended. The vertical or vertical direction is thus the direction which, when the vehicle is used as intended, runs parallel to the weight acting on the earth on a flat stretch of road. The axis preferably runs horizontally and thus perpendicular to the said vertical or vertical direction.Horizontal alignment of the axle can be particularly advantageously determined by enclosing the first fixing section with the second fixing section, a vertical position of the fixing sections relative to one another. When providing a bracket as the second fixing section, it can be sufficient for the bracket to delimit the first fixing section only at its vertical upper side in the fixing state, since the vehicle in the fixing state rests with its wheels and thus its vertical underside on a floor to which the station is attached or which the station itself forms, so that simply by enclosing the first fixing section at its vertical upper side, the position range over which the fixing device and fixing means, and thus the first and second fixing sections, can move relative to one another along the vertical direction, is sufficiently delimited. The second fixing section, which is designed in the manner of aRing or bracket is formed, furthermore on at least one horizontal side of the first fixing section, so that it limits the movement of the first fixing section along a horizontal direction in one direction. Preferably, the second fixing section encloses the first fixing section at its two ends with respect to this specific horizontal direction. Preferably, that of the fixing device and fixing means which has the first fixing section has a recess in which the second fixing section is arranged in the fixing state and which is arranged on both sides of the second fixing section with respect to the said axis. By arranging the second fixing section in this recess, the mobility of the fixing means and fixing device relative to one another is therefore also limited along the said axis, so that the position range of the fixing means andFixing device, over which the relative position of the fixing device and the fixing device can vary. Particularly preferably, the arrangement of the first fixing section in the second fixing section limits a relative movement of the fixing device and the fixing device in two mutually perpendicular spatial directions, which each run perpendicular to the axis, whereas the relative movement of the fixing device and the fixing device along the said axis is limited by the arrangement of the second fixing section in the said recess, wherein the position range to which the relative movement along the axis is limited is larger than the position range to which the relative movement in at least one of the said spatial directions perpendicular to the axis is limited, in particular larger than the two position ranges to which the relative movement along the two spatial directions perpendicular to the said axisspatial directions in each case. This ensures the best possible positioning of the charging connection and the charging device relative to one another, which is required to implement a charging process, due to the determination of the position of the fixing device and the fixing device relative to one another, and at the same time enables the simplest possible connection of a vehicle to the station. Generally preferably, the fixing device has the second fixing section. Thus, the vehicle has the second fixing section, while the station has the first fixing section and the locking device. This allows the design of the vehicle to be kept as simple as possible. Generally preferably, the system, in particular the station, has a control device for controlling the locking device, wherein the control device defines when and in what manner the locking device moves the first fixing section in order to optionally, depending on the specification of theControl device and resulting from the movement of the first fixing section, to realize the release state and the fixing state. Generally, the second fixing section is preferably provided in a permanently fixed position on the vehicle. Particularly preferably, the second fixing section is provided on the basic structure of the vehicle, in particular on the frame, in particular on the steering tube. The permanently fixed position of the second fixing section on the vehicle ensures that the second fixing section can only be separated from the rest of the vehicle by destruction or only by means of a special tool that is not accessible to a normal user. In one embodiment, the fixing device has a track holder for determining a position of at least one of the wheels of the vehicle with respect to a direction along the wheel axis of the respective wheel relative to the station in the fixing state. The track holder can, for example, be provided bya U-shaped rail designed to accommodate one or all of the wheels of the vehicle. In one embodiment, the track holder has two rails spaced apart from one another with respect to the direction running along the wheel axis, wherein in the fixed state, the wheel is arranged between the rails. In any case, the track holder is designed to limit movement of the wheel along its wheel axis in the fixed state. The track holder thus contributes to the alignment of the vehicle and thus to the alignment of the charging port relative to the station in the fixed state. Thus, generally, the track holder preferably has two side walls, between which at least one of the wheels of the vehicle is arranged in the fixed state and which thus limit the mobility of this wheel along its wheel axis. In one embodiment, at least one of the wheels of the vehicle forms at least a portion of the fixing device, so that theThe wheel support and the at least one wheel of the vehicle in the fixing state contribute to the fixing of the fixing device and the fixing means to one another in a positional range, as explained above. In another embodiment, the fixing device is formed exclusively by the basic structure of the vehicle and thus not by the wheels of the vehicle. In one embodiment, the wheel support has two side walls, wherein at least one of the side walls has a reset device and, on its side facing the other of the side walls, a wall section which is connected to the reset device and which, starting from a rest position, can be moved away from the other of the side walls against a reset force formed by the reset device, thereby increasing the distance between the side walls. In this embodiment, the distance between the side walls, which they have in the fixing state along the wheel axis of the wheel between themarranged wheel from each other, variable. Thus, the distance can be adapted to different wheel widths or different track widths. The distance between the side walls is defined by the distance between the wall section of said side wall and the other side wall. Preferably, both side walls each have such a wall section and such a restoring device, so that the distance between the side walls is determined by the distance between their wall sections. Due to the provision of the restoring device, it can always be ensured that a force is required to increase the distance between the side walls starting from the rest position, so that the restoring device acts to guide a wheel arranged between the side walls. Particularly preferably, the restoring device is designed as a spring device. In one embodiment, the restoring device is a spiral and / or leaf spring device.and the wall section is formed by a sheet metal that is supported by such a spring device relative to a stationary support. In one embodiment, the wall section is rotatably mounted on a stationary support via a rotation axis, wherein a rotation of the wall section to increase its distance from the other side wall requires the application of a force. In this case, for example, the wall section can be subjected to a restoring force purely due to a weight force and / or due to a spring force. Generally preferably, the side wall having the wall section has a support whose position is fixed, wherein the wall section is movable relative to this support while overcoming the restoring force. Generally preferably, the restoring device is designed such that, when the wall section is deflected from its rest position, it acts to cause the wall section to return to its rest position. InIn one embodiment, the charging device and at least that of the first and second fixing sections encompassed by the fixing device are arranged together in a housing part of the station. The housing part forms an interior space in which the charging device and the said fixing section are arranged. The housing part can, for example, be box-shaped. By arranging the charging device and the said fixing section in one housing part of the station, a particularly good alignment of the charging connection to the charging device in the fixing state can be particularly favored. Furthermore, the locking device of the station is particularly preferably arranged in the housing part of the station. Furthermore, a control device of the station is particularly preferably arranged in the housing part of the station. Generally, the station preferably has a stand body, by means of which it can be placed on a floor and mounted thereon. The stand body canfor example, be formed by a frame structure or a plate structure. Particularly preferably, the housing part is fixed in a fixed position to the base body of the station. Particularly preferably, the base body of the station is manufactured separately from the housing part of the station, but is permanently connected to the housing part of the station and thus securely fixed thereto. Thus, when the station is used in a public space, the housing part cannot be detached from the base body of the station by a public person without causing damage. In one embodiment, the charging connection and at least that fixing section formed by the fixing device are integrated together in a unit of the vehicle. For example, the vehicle can have a housing part in which the charging connection and said fixing section are arranged. Preferably, the charging connection and the entire fixing device are integrated together in said unit of theVehicle integrated. Generally preferably, the vehicle unit is designed as an adapter manufactured separately from the rest of the vehicle and mounted on the rest of the vehicle. Generally preferably, said unit is designed as an adapter mounted on the basic structure of the vehicle, in particular on the steering tube or handlebar of the vehicle. The adapter can be subsequently mounted on the basic structure after the manufacture of the basic structure or after the manufacture of the rest of the vehicle. Particularly preferably, the adapter is detachably mountable, wherein detaching the adapter is preferably only possible using special tools, i.e. not with commercially available tools. By integrating the charging connection and the said fixing section in the unit, the system can be designed to be open to a variety of different vehicles, wherein the vehicles can be provided by different vehicle fleet providers. Thus,For example, an organization, such as a city administration, can arrange for the installation of system stations in its territory and oblige every vehicle fleet provider who wishes to offer vehicles for use in the organization's territory to equip its vehicles with such an adapter so that they are designed as part of the system and thus as a vehicle of the system and function accordingly as part of the system. The particularly preferred embodiment can thus make a particularly advantageous contribution to ensuring a sensible distribution and the maintenance of a desired order in the territory of such an organization. Particularly preferably, the unit comprises a location module, for example a GPS module, GLONASS or GALILEO module. Such a location module is designed to determine location data of the vehicle. By the unit, which as explained is preferably designed as an adapter,itself has such a location module, the movement history of the vehicle can be tracked via the unit itself and thus independently of other components of the vehicle. This makes it possible to track the movement of the vehicle purely on a vehicle-related basis, independent of user data, from which conclusions can be drawn about a sensible distribution of vehicles and typical, anonymized user histories. Particularly preferably, in addition to the location module comprised by the unit, the vehicle has a further location module which is designed to recognize and output location data of the vehicle and via which, for example, a vehicle fleet provider can monitor the vehicle or its use. Particularly preferably, the unit or the adapter has a memory for storing a location history of the vehicle. Particularly preferably, the unit or the adapter has a wireless interface via which the location data can be read out wirelessly.Generally, the memory can preferably be readable, in particular via the wireless interface. By providing such a memory and / or such a wireless interface, the aforementioned location data and thus movement data can be obtained from the unit itself. Particularly preferably, the unit is designed to store the location data in the memory as a function of time and / or to output it to the wireless interface, so that a time-dependent movement history of the vehicle can be obtained by means of the unit and read out therefrom, either by reading the memory or by directly reading the wireless interface. This can enable an organization or an operator employed by the organization to obtain data from which sensible distributions of system stations at defined locations and / or a sensible distribution of system vehicles at defined locations,in particular, a time-dependent distribution of the system's vehicles at specific locations can be determined. By designing such a unit as an adapter, such an organization or an operator employed by it can track all of the system's vehicles, even if they are provided by different fleet providers, along with their location history, independently of any user data of the vehicle users, and thereby obtain data that is conducive to the sensible operation of the entire system, whereby, for example, the location- and time-dependent availability of vehicles across the entire area, i.e. across the entire territory for which the respective organization is responsible, is determined depending on this data, i.e. that the locations at which a certain number of the system's vehicles are to be kept available for users, i.e. at specific stations of the system, are determined time-dependently.are to be held in the fixing state, wherein each of the specific stations is assigned a specific location. A location can, for example, be uniquely identified via GPS coordinates. In one embodiment, the charging device comprises a primary coil with a primary coil axis, and the charging port comprises a secondary coil with a secondary coil axis. The secondary coil axis is thus the coil axis assigned to the secondary coil, and the primary coil axis is the coil axis assigned to the primary coil. Particularly preferably, due to the interlocking of the fixing device and the fixing device in the fixing state, an angle formed by the primary coil axis with the secondary coil axis is set to less than 30°, in particular less than 20°, in particular less than 10°. In the fixing state, the vehicle can therefore only be in a position relative to the station such that the angle between the primary and secondary coil axes is less than 30°, in particularless than 20°, in particular less than 10°. As a result, the efficiency when charging the vehicle's battery in the fixed state can be particularly high due to the interaction of the charging device and the charging connection. Particularly preferably, in the fixed state, the primary coil axis and the secondary coil axis are each fixed to an orientation in which they have an angle of more than 45°, in particular more than 60°, in particular more than 70° to the vertical by the engagement of the fixing device and the fixing device. This can be particularly advantageous for increasing the efficiency when charging the battery. In particular, such an alignment can advantageously make it more difficult for dirt to deposit across the flat extent of the primary and secondary coils at the charging connection or charging device. By making such dirt deposits more difficult, the efficiency can be improved. Particularly preferably, in embodiments in whichthe primary coil axis does not run perpendicular to the vertical and thus the coil cross section of the primary coil does not point in the vertical direction, i.e. does not run perpendicular to the vertical direction, the primary coil with its coil cross section on its side facing the charging connection in the fixing state downwards. In one embodiment, the primary coil and the secondary coil each have a coil cross section perpendicular to their respective coil axis, wherein over the entire position range to which the relative position of the fixing device and the fixing means to one another is fixed in the fixing state, at least 50%, in particular at least 60%, in particular at least 70%, in particular at least 80% of the coil cross section of a first of the primary and secondary coils, the coil cross section of which is smaller than or equal to the coil cross section of a second of the primary and secondary coils, completely coincides with the coil cross section of the second of the primary andSecondary coil overlaps. At this point, it should be noted that the overlap of the coil cross-sections of the primary and secondary coils is particularly advantageous for achieving high efficiency. The primary and secondary coils can each have the same coil cross-section or differ from one another in their coil cross-sections. The inventors have recognized that it is particularly advantageous to ensure that the coil cross-sections overlap as much as possible in the fixing state, wherein when two equally sized coil cross-sections of the primary and secondary coils are provided, a first of these coils preferably overlaps, as explained, by at least 50% with the coil cross-section of a second of the primary and secondary coils, wherein when two different coil cross-sections are provided, it is preferably provided that at least the coil cross-section of that of the primary and secondary coils which is smaller than the coil cross-section of theother of the primary and secondary coils, overlaps as predominantly as possible with the coil cross-section of the other of the primary and secondary coils. In one embodiment, by the interlocking of the fixing device and the fixing means in the fixing state, a position of the charging connection to the charging device is set to such a position range in which charging of the battery with at least 70%, in particular at least 80%, in particular at least 90% of a maximum charging power, which indicates a maximum charging power that can be transferred from the charging device to the battery via the charging connection, is ensured. The maximum charging power can be achieved if the charging connection is positioned as sensibly as possible relative to the charging device in order to optimize efficiency. Such an absolutely optimized positioning cannot be fully ensured by the system according to the invention in the fixing state. However, the inventors have recognized that preferablyThe fixing device and the fixing unit are designed to correspond to one another in such a way that, in the fixing state, they fix the charging device and the charging connection to a positional range relative to one another such that charging of the battery is ensured with a high degree of efficiency over the entire possible positional range. As explained, various measures can be taken to keep the efficiency as high as possible over the positional range, for example by designing the fixing device and the fixing unit as complex as possible or by designing the primary and secondary coils with the largest possible surface area. The inventors have recognized that by defining a certain positional range, cost-effective production of the system and easy handling of the system by a user, in particular a simple implementation of the fixing state, is possible if the efficiency is maintained over the specifiedmay in any case experience a certain fluctuation across the position range, but remains above a certain minimum value. This is because an energy-saving and thus economical charging of the battery by the station can be ensured, while at the same time low manufacturing costs and ease of handling can be ensured. Particularly preferably, the system is designed such that, through the engagement of the fixing device and the fixing means in the fixing state, the position of the charging connection relative to the charging means is fixed in a position range in which, depending on the position within the position range, charging of the battery fluctuates at least between 85% and 100%, in particular at least between 80% and 100%, of the stated maximum charging power, wherein, however, it is ensured across the position range that charging of the battery with at least 70% of the maximum charging power is ensured. In one embodiment, theStation several charging devices and several fixing devices and the system comprises several vehicles, each having a fixing device assigned to it, a battery assigned to it, a charging connection assigned to it and several wheels assigned to it. The components of the respective vehicle can have properties that are explained here with reference to a vehicle of the system. Preferably, the fixing device of each vehicle of the system is designed to correspond to each fixing device of the system and the charging connection of each vehicle of the system is designed to correspond to each charging device of the system. Thus, each of the vehicles of the system can be designed as the one vehicle that is parked here when explaining various embodiments of the invention, which can be parked at a specific station of the system and in the process at the stationcan be fixed by realizing the fixing state of the system. In one embodiment, in the fixing state, all vehicles of the system are fixed in a fixed position to a respective fixing device of the system assigned to them. Preferably, in the fixing state of the system, the vehicles of a selected group of vehicles of the system are each parked at a station of the system and fixed in a fixed position thereto, as explained here in connection with various embodiments with reference to a vehicle. In one embodiment, the system has several vehicles, wherein in the fixing state, each of these several vehicles is fixed in a fixed position to one of the fixing devices of a particular station of the system and the vehicles are held side by side at this station, wherein two adjacent vehicles are held at the station offset from one another along their direction of travel. The vehicles areare arranged side by side with respect to a direction perpendicular to their respective direction of travel, but are offset from one another along their direction of travel. This has the particular advantage that the vehicles can be held at one station in a particularly space-saving manner, since laterally projecting components of the vehicles, such as their handlebars, can be offset from one another. Particularly preferably, the system comprises, in addition to the several vehicles mentioned and several fixing devices, a group of further vehicles and a group of further fixing devices. This group of further fixing devices and of further vehicles can of course be designed as generally explained for the fixing devices or vehicles of the system. In a particularly advantageous embodiment, in the fixing state, not only each of the several vehicles is attached to one of the severalNot only is the fixing devices of the station fixed in position, but in addition each of the further vehicles, i.e. the group of further vehicles, is fixed in position to one of the further fixing devices, i.e. the group of further fixing devices, wherein the further vehicles are held next to one another at the station, as explained above with regard to the plurality of vehicles, wherein two adjacent ones of the further vehicles are held at the station offset from one another along their direction of travel, as explained above with regard to the plurality of vehicles. Particularly preferably, one of the further vehicles together with one of the above-mentioned plurality of vehicles forms a pair of vehicles which are opposite one another with their front sides, wherein in particular the fixing devices of the station, to which they are each held in position in the fixing state, at least in sections between the two vehicles of the pair,in particular between their mutually facing front sides. The system can thus comprise a first group of vehicles and a second group of vehicles as well as a first group of fixing devices and a second group of fixing devices. Each group of vehicles is arranged next to one another, with the vehicles of the different groups facing each other with their front sides. The plurality of vehicles form the first group, the further vehicles the second group of vehicles of the stations, and accordingly the plurality of fixing devices form the first group and the further fixing devices the second group of fixing devices of the system. By providing two such groups or the corresponding design of the station, a particularly large number of vehicles can be held at the station in a particularly space-saving manner. The station particularly preferably comprises a stand body which has a zigzag-shaped profilewherein, in the fixed state, the plurality of vehicles, i.e. the first group of vehicles, are arranged on a first side of its course, and the further vehicles, i.e. the second group of vehicles, are arranged on a second side of its course, so that it runs with its zigzag course between a first group of vehicles, which is formed by the plurality of vehicles, and a second group of vehicles, which is formed by the further vehicles. The vehicles of the respective group are thus arranged next to one another along the course of the stand body, wherein the stand body runs between the two groups of vehicles, so that a group of vehicles is arranged on each side of the stand body, which then face each other with their front sides. This can ensure a particularly space-saving and cost-effective arrangement and storage of the vehicles of the system. In one embodiment, theThe system comprises a load management device, wherein the load management device is designed to determine, in a charging state in which the system is in the fixed state and a plurality of the vehicles fixed at the station are coupled with their respective charging connection to one of the charging devices for receiving a charging power, the charging power output by the respective charging devices to the charging connection assigned to them in each case as a function of a charging power state of the station, which characterizes a charging property of the station as a whole. Preferably, the station at which the plurality of vehicles is provided has the load management device. In the charging state, each vehicle is assigned one of the charging devices of the station and thus each charging connection is assigned one of the charging devices. In the charging state, each charging connection is coupled to the assigned charging device such that aCharging of the battery of the vehicle that has the charging connection is possible. The higher-level load management device can determine and thus control the output of the charging power depending on the charging power state of the station. The charging power state characterizes at least one charging property of the station, for example an intended total charging power, a total charging current and / or a total charging capacity of the station. Thus, for example, it can be determined that the station only charges vehicles at the station with a maximum total charging power or a maximum total charging current, so that the charging power output at the respective charging connection is determined depending on the total charging power or the total charging current in order to avoid overloading the station. The station particularly preferably has a station battery, wherein the charging power output at the charging connections is determined depending on theTotal charging capacity, which corresponds to the state of charge of the station battery, is determined. For example, the dependency of the output charging power can be determined taking into account a previously known, expected time-dependent profile of the total charging capacity. For example, a known point in time at which charging of the station battery is expected can be included in the dependency. In one embodiment, the station has a station battery whose capacity is at least 10 times the capacity of the vehicle battery. If several vehicles are provided, the capacity of the station battery can be at least 10 times the capacity of the battery of each vehicle. Particularly preferably, the station battery is at least 100 times, in particular at least 1000 times the capacity of the vehicle battery. By providing such a station battery, the station can be particularly easy to use andbe set up, since no significant electrical infrastructure needs to be provided at the location where the station is set up. This means that the station can be set up easily and, if necessary, also mobile at locations where there is little space available but it is still needed. In contrast to the usual operation of battery-powered vehicles, which requires that each vehicle be collected and charged individually, only the station battery needs to be charged at the station so that all vehicles can be charged. The station particularly preferably has a weight of more than 100 kg, in particular more than 200 kg. This allows the station to be easily secured against vandalism and theft. The station is particularly preferably designed to, when the system is fixed and in particular when the system is charged, charge the vehicle independently of a connection to aInfrastructure to maintain and charge so that the station can charge the vehicles without being connected to a power grid. Particularly preferably, the station has a photovoltaic element for the autonomous charging of its station battery. This allows the energetic and financial expenditure for charging the vehicles of the system to be kept as low as possible, since the station can, if possible, charge its station battery itself via its photovoltaic element and thus additional charging by mobile personnel can only be provided if the photovoltaic element is insufficient. Particularly preferably, the station is connected via an interface to a central processing unit of the system, wherein the total charging capacity of the station, i.e. the charge level of the station battery, is monitored via the central processing unit, wherein charging of stations is only carried out in a targeted manner depending on the total charging capacity, i.e. the charge level of the station battery.is carried out. In one embodiment, the system has at least a subset of vehicles, each of which is designed without a charging connection, but has a fixing device. The fixing device is designed to correspond to the fixing device of the station. Thus, each of the vehicles of the subset can be releasably fixed in a fixed position at the station, as explained here, due to the corresponding design of the fixing device and the fixing device. Particularly preferably, the fixing section formed by the fixing device is also formed by an adapter in the subset of vehicles, which adapter can be mounted on the rest of the vehicle, as explained above. In such a particularly advantageous embodiment of the system, vehicles can thus be specifically provided in the system that can be used cost-effectively by a user, since the user only has to ensure that his vehicle can be fixed to thestation, but not the charging option at the station. This can further improve the ecological and financial benefits of such a station. In one embodiment, the system has a detection device for detecting the presence of the vehicle in such a position relative to the station in which the locking state can be achieved solely by moving the first locking section by means of the locking device. The system is thus designed to detect that the vehicle is arranged relative to the station such that the system is in the released state, and that the locking state can be achieved solely by moving the first locking section by means of the locking device, starting from the released state. The detection device can, for example, comprise an optical detection device, such as a camera, and / or a reading device, such as reading a QR code located on apredefined position on the vehicle, and / or a resistive or capacitive switch that detects the corresponding presence or position of the vehicle relative to the station. The detection device can additionally or instead also be designed as a manual detection device, so that by manually actuating a section of the detection device, for example a switch, lock or the like, the fixing state can be realized and thus the vehicle can be locked at the station. However, the detection device is particularly preferably an automatic detection device that automatically detects the presence of the vehicle or the said position of the vehicle without manual actuation by a user. The system particularly preferably has a control device that is designed to actuate the locking device upon detecting the said position of the vehicle in order to realize the fixing state.Particularly preferably, the system is designed to automatically detect the said position of the vehicle via the detection device, i.e., without user-initiated detection, and to automatically actuate the locking device after the automatic detection of the position to implement the locking state, i.e., without deliberate user initiation. This ensures in a particularly simple and reliable manner that a vehicle, as soon as a user brings it into the corresponding position at the station, can be reliably held fixed to the station and, in particular, can also be loaded from the station. In one embodiment, the system includes an authentication device. The authentication device can be included in the above-described detection device or can include it or be formed together with it in a single unit. Authentication device and / or detection device arepreferably encompassed by the station. The system is preferably designed to actuate the locking device for moving the first fixing section to realize the release state starting from the fixation state only if an authentication has previously been established by the authentication device. This can effectively prevent unauthorized release of the vehicle from the station. Particularly preferably, the authentication device has a wireless interface for wirelessly detecting an authentication. Such a wireless interface can be, for example, a Bluetooth, WLAN or NFC interface. For example, authentication by means of a mobile terminal, in particular a smartphone, can be enabled via the wireless interface, for example by direct coupling between the smartphone and the authentication device or by indirect coupling via an internet connection, which on the one hand is connected tothe smartphone and, on the other hand, with the authentication device. Particularly preferably, the recognition device is designed to recognize an authentication of a first type and to recognize an authentication of a second type, wherein the system is designed, upon recognition of the authentication of the first type, to actuate the locking device to implement the locking state and to prevent the charging device from outputting charging power, and upon recognition of the authentication of the second type, to actuate the locking device to implement the locking state and to control the charging device to output charging power. According to this particularly preferred embodiment, the system can thus distinguish between two different authentications: a user who only has an authentication of the first type can only park his vehicle at the station and then, whereas aA user who has authentication of the second type can also have his vehicle charged by the station while in the fixed state. Such an embodiment has the particular advantage that a wide range of functionality can be provided with just one technical station. With just one station, both an operator of a vehicle fleet registered with this station and a vehicle fleet operator not registered with this station or a private individual can use the station. The station can therefore be set up in a public space, for example in large numbers in a large city, in a cost-, material- and space-saving manner. It is particularly preferred that the system, in addition to the described detection device, also comprises the described authentication device, wherein, based on the fixed state of the system, upon detection of an authentication of the first type or the second type or uponRecognition of an authentication of a third type, which is only authorized to remove the vehicle from the station, the locking device is controlled to move the first fixing section to realize the release state starting from the fixing state. In one embodiment, the system comprises a plurality of stations, a plurality of vehicles and a central processing unit. The vehicles each have a communication interface for wireless communication with a mobile device. Preferably, the communication interface is designed as a Bluetooth, WLAN, and / or NFC interface. Communication with the mobile device can take place directly with the mobile device or indirectly, in that the mobile device and the communication interface are each connected to the Internet and communicate with each other via the Internet. The communication interface can be the wireless interface of theAuthentication device can be designed or provided in addition to this. The mobile device can be, for example, a smartphone, tablet or similar. Each of the vehicles further comprises a locking device. The locking device can be switched into a locked state and, alternatively to the locked state, into an unlocked state. In the locked state, use of the vehicle's electric motor to use the battery-powered vehicle as intended is prevented. In the unlocked state, use of the vehicle as intended and thus use of its electric motor, which is powered by the battery, is enabled. Via the communication interface, the locking device can be switched into the locked state and, alternatively, into the unlocked state by means of the mobile device, regardless of the positioning of the respective vehicle relative to the station. The locking device can thus be used both when the vehicle is positioned at the station andcan also be switched to the locked state or released state when the vehicle is positioned far away from the station. The computing unit is preferably designed to determine the location of each vehicle and to assign one of the stations to the respective vehicle as a target station and to determine whether the respective vehicle is away from the target station assigned to it. The computing unit is designed to credit a user account associated with the identification whenever it has determined the distance of the respective vehicle from the target station and has determined an identification of the mobile terminal and a travel command associated with the identification with reference to the respective vehicle and has subsequently determined a positioning of the vehicle at the target station. The travel command preferably causes the locking device, after previously having been in the locked state,is switched to the release state. The identification can, for example, be the authentication explained above. Each identification of a mobile device is assigned to a specific user account. Identification is therefore only possible if a corresponding user account has been created and is assigned to the mobile device. The user account is thus referenced on the computing unit. Particularly preferably, the respective vehicle is initially removed from the target station while its locking device is in the locked state, with the mobile device then being identified, as a result of which the locking device assumes the release state, with the computing unit assigning a specific target station to the vehicle removed from the target station and only crediting the user account if the computing unit determines that the vehicle that was first removed from the defined target station has been moved to one of the identificationassigned driving command, which includes at least the change of the locking device from the locked state to the released state, has been positioned at the target station, wherein it is preferably provided that the credit is only attributed to the user account if the computing unit determines that the respective vehicle is located at the target station and its locking device is in the locked state and / or is fixed in position at the target station by means of its fixing device and / or its battery is charged by means of its charging connection from the charging device of the target station. The particularly advantageous embodiment thus creates an incentive for a user, regardless of the desired use of the vehicle, to bring the vehicle to a target station if it is not located at one. In one embodiment, it is provided that such a credit is only attributed to the user account by the computing unit if the vehicleis initially located away from any station and is therefore not fixed in position at a station by means of its fixing device, whereby only due to the travel command, which is linked to the identification, is the vehicle brought to one of the stations and fixed in position at this station by means of its fixing device. In this case, for example, any station of the system can be defined as a target station. In another embodiment, only a specific station of the system or a specific group of stations of the system is defined as a target station, so that by assigning the credit or the incentive created thereby, a targeted spatial distribution of the vehicles is supported. It should be taken into account that each station can be assigned a location that is uniquely identifiable, for example, by means of GPS coordinates. By only a specific group of stations, which preferably only a single one of thestations is defined as the target station, a credit can only be issued if the vehicle that was initially spatially distant from this station is brought to the location assigned to this station. This can have the particular advantage that any user who has a user account assigned to a corresponding identification can contribute to a desired spatial distribution of the vehicles in the system. The credit can, for example, be a credit on a user account, which the user can then invest in a desired use of the vehicle. In one embodiment, the credit can also be a monetary amount that is reimbursed to the user. In one embodiment, the computing unit is designed to transmit information to the mobile terminal in response to a query assigned to the identification, which information contains location details of at least one vehicle thatfrom each of the stations or at least from a group of target stations and whose locking device is in the locked state. Thus, a user who has a user account and thus an identification assigned to this user account can specifically request location information from the computing unit about at least one vehicle that is at least from the group of target stations (which in any case includes at least one station of the system), in particular from each of the stations, and whose locking device is in the locked state. The user can thus specifically obtain information about a vehicle via this location information that should preferably be brought to a target station or at least to any station of the system. Thus, the user can earn a credit by being directed to the corresponding vehicle from the location information and then sending this vehicle to thetarget station and parks it there in its locked state. In one embodiment, the computing unit is designed to dynamically select a specific group of the plurality of stations on the basis of a dependency stored in the computing unit and to transmit each station of the specific group as a target station to the mobile device. The computing unit is thus automatically able to identify certain of the stations of the system as a target station. As a result, a corresponding dependency is defined in the computing unit. Thus, the computing unit can provide for a targeted distribution of the vehicles to specifically selected stations. Particularly preferably, the dependency stored in the computing unit takes into account a frequency, stored in the computing unit, of a removal of vehicles previously fixed in a fixed position at the respective stations of the system from the stations. Thus, the computing unit is designed toof vehicles from the stations and to determine the dependency, on the basis of which the respective target station or group of target stations is identified, depending on the determined frequency of removal of vehicles at the respective station of the system. Particularly preferably, the computing unit is designed to automatically and dynamically determine the stored frequency from time-dependent location data determined by the vehicles of the system. Thus, the system can be designed to automatically determine the frequency by tracking the locations, in particular the time-dependent locations, of the vehicles of the system. In this case, the determination can always be dynamic, i.e. can be dynamically changed over time by continuously determining the corresponding data. In one embodiment, the dependency stored in the computing unit comprises a time-of-day and location-dependent function stored in the computing unit, whichTime-of-day and location-dependent frequency of vehicle use is defined. This is based on the vehicle use at the respective station. By characterizing the vehicle use at the respective stations of the system accordingly with regard to its frequency, a group of stations, in particular exactly one of the stations, can be specifically identified as the target station. The time-of-day and location-dependent frequency of vehicle use can be determined, for example, taking into account the frequency of vehicle use at the respective stations determined by the station itself and / or taking into account a frequency of use expected based on previously known events, such as the end of a concert or the end of a football match. Particularly preferably, the function comprises usage information obtained independently of the system. Such usage information obtained independently of the system can, for example,a specific event, i.e. its location and time with its impact on the expected frequency of vehicle use at the specific location at the specific time. Such an event may, for example, be the end of a concert or football match or, for example, the known location and time of rush hour, which may, for example, be at least partly determined by a previously known time of the end of operations. In one embodiment, the amount of the credit depends on a time of day and / or on the location of the target station. Thus, in the case of a known, particularly high demand for vehicles at a specific location at a specific time, a particularly strong incentive can be set so that users bring the vehicles to a target station assigned to the respective location at a specific time of day and receive a credit with the largest possible amount. This allows an ecologically particularly valuableA contribution can be made, since without providing external transport measures and thus with the lowest possible energy consumption, a desired spatial and temporal distribution of the vehicles can be realized, which in turn can achieve the most environmentally friendly use possible by users who want to reach a specific location. The invention further relates to a method for keeping a battery-operated vehicle, which has a fixing device, a battery, a charging connection, several wheels and in particular a track width of less than 50 cm, ready at a station, which comprises a fixing device corresponding to the fixing device for fixing the vehicle in a fixing state of the system as well as an inductive charging device for inductively charging the battery in the fixing state by means of the charging connection. At this point, it should be generally pointed out that the vehicle naturally has an electric motor, which is used forDriving at least one of the wheels and which is supplied by the battery when the vehicle is used as intended. The battery-operated vehicle is thus designed to be driven by an electric motor which is supplied by the battery. According to a solution according to the invention, for the secure fixing of the vehicle at the station, a first fixing section designed in the manner of a movable bolt is inserted into a second fixing section designed as a receptacle for the first fixing section. In this case, one of the first and second fixing sections is formed by the station and the other of the first and second fixing sections is formed by the vehicle. According to a further solution, for the removal of the vehicle from the station, which is securely fixed to the station, a first fixing section and a second fixing section engage with one another, wherein one of these fixing sections is formed by the station and the other by theVehicle is designed, the first fixing section is removed from the second fixing section and then the vehicle is removed from the station. Particularly preferably, to release the vehicle from the station, starting from its fixed state in which it is securely fixed to the station, only the first fixing section is removed from the second fixing section. Particularly preferably, the vehicle is loaded while it is securely fixed to the station and is held in its position relative to the station only by the interaction of the fixing device and the fixing apparatus. Particularly preferably, starting from a state in which it is securely fixed to the station and is being loaded, the vehicle is brought into a state in which it can be freely removed from the station solely by moving the first and second fixing sections towards each other. In the above-mentioned states, the above-explained fixing state or release state of the systembe realized. In a particularly advantageous embodiment of the method according to the invention, the station automatically detects when the vehicle is in such a position relative to the station that it can be securely fixed thereto, wherein after such detection, the station automatically controls the locking device such that the first fixing section is inserted into the second fixing section, so that these two fixing sections engage with each other such that the vehicle is held securely in position at the station. Particularly preferably, in a state in which the vehicle is held securely at the station, the station automatically determines via the charging device whether charging the vehicle's battery via the charging connection is possible and / or advantageous, and if the determination is affirmative, the station automatically charges the battery through the interaction of the charging device and the charging connection.carried out while the vehicle is securely fixed to the station. Particularly preferably, a charging process that is carried out while the vehicle is securely fixed to the station is automatically interrupted by the station as soon as the vehicle is released from the station. In one embodiment, a distinction is made between different authentication types, wherein upon detection of an authentication of a first type when a vehicle is parked at the station, the vehicle is only securely fixed to the station, and only upon detection of an authentication of a second type, but not upon detection of an authentication of the first type, is the vehicle both securely fixed to the station and charged from the station when a vehicle is parked at the station.

Figure 1 shows an embodiment of a system according to the invention in its fixed state. The system comprises a station 2 with a stand body 21 and a housing part 22. The system further comprises a vehicle 1 with a front wheel 12 and a rear wheel 11 as well as a basic structure, which has a frame 14, over which theWheels 11, 12 are connected to one another, a steering tube 13 and a handlebar 15. The vehicle 1 further comprises a charging connection 16 and a fixing device 17. In the fixing state shown in Figure 1, the vehicle 1 stands with its wheels 11, 12 and the station 2 stands with its base 21 on a common floor. Through the interaction of the fixing device 17 with a fixing device 27 of the station 2 shown in Figure 2, the vehicle 1 is securely fixed relative to the station 2. The charging connection 16 is positioned in a predefined position range relative to a charging device 26, as shown in Figure 2, so that in the fixing state a battery of the vehicle 1 (not shown in Figure 1) can be charged by the charging device 26 by means of the charging connection 16. The charging device 26 and the fixing device 27 are both integrated into the housing part 22, which is attached to the stand body 21 of the station 2.Figure 2, comprising Figures 2a and 2b, shows station 2 and vehicle 1 of the embodiment according to Figure 1, each in a sectional view. The section runs along the vertical direction and along a horizontal direction that is perpendicular to the vertical direction. Said horizontal direction corresponds to the direction in which vehicle 1 travels when traveling straight ahead. The vertical direction corresponds to the direction along which vehicle 1 rests with its wheels 11, 12 on a ground or road during intended use. Figure 2a shows a section through station 2. Figure 2b shows a section through vehicle 1. Figure 2a shows that charging device 26 and fixing device 27 are arranged in housing part 22 of station 2. Charging device 26 forms a recess for charging connection 16. Charging device 26 comprises a primary coil 28, and charging connection 16comprises a secondary coil 18. The fixing device 27 comprises a bolt 270, and the fixing device 17 comprises a bracket 170. The station 2 further comprises a locking device (not shown) which is designed to move the bolt 270 along its bolt axis. When the vehicle 1 approaches the station 2 in such a way that the charging connection 16 is located in the recess of the charging device 26 and the fixing device 17 is located with its bracket 170 in the recess formed by the fixing device 27, the bolt 270 can be inserted along its bolt axis into the receptacle enclosed by the bracket 170, whereby the vehicle 1 can be held fixedly and securely in place at the station 2. This realizes the fixing state of the system. By arranging the bolt 270 in the receptacle formed by the bracket 170, the relative position of the fixing device 27 and the fixing device 17 with respect tothe vertical direction and the said horizontal direction, whereas the relative position with respect to a further horizontal direction, which is perpendicular to the vertical direction and the said horizontal direction and corresponds to the bolt axis that encloses the bracket 170, is determined by the arrangement of the fixing device 17 in the recess of the fixing device 27. In this fixing state, the primary coil 28 and the secondary coil 18 are formed substantially parallel to one another and overlap with their coil cross-sections substantially completely and are only very slightly spaced from one another along their coil axes. Thus, the interlocking of the fixing device 17 and the fixing device 27 ensures such a positioning of the vehicle 1 relative to the station 2 in the fixing state that the battery of the vehicle 1 is charged with ahigh efficiency. Figure 3 shows a further, highly simplified schematic diagram of a further embodiment of a system according to the invention in its fixed state. Components of the embodiment according to Figure 3, which essentially correspond to the components of the embodiment according to Figures 1 and 2, are designated by the same reference numerals. In the embodiment according to Figure 3, the supporting body 21 is plate-shaped. A track holder 23 is arranged on this supporting body 21 and is fixedly connected thereto. In the present case, this consists of two rails, between which both the front wheel 12 and the rear wheel 11 of the vehicle 1 are arranged in the fixed state. Accordingly, the rails of the track holder 23 are spaced from one another with respect to a direction running parallel to the wheel axes of the wheels 11, 12, so that the wheels 11, 12 can be arranged between them. Figure 3 showsthat the track holder 23 contributes to the positioning of the vehicle 1 relative to the station 2. On the front of the vehicle 1 (not shown in Figure 3), as in the embodiment shown in Figures 1 and 2, a bracket 170 is provided as a second fixing section, and on the station 2, analogously to the embodiment according to Figures 1 and 2, a bolt 270 is provided as a first fixing section, so that the relative position of the vehicle 1 relative to the station 2 is determined both by the interaction of bolt 270 and bracket 170 and by the interaction of the wheels 11, 12 with the track holder 23. The fixing section formed by the fixing device and the charging device are integrated in a housing part 22 of the station, and the fixing section formed by the fixing device and the charging connection are integrated in a unit of the vehicle 1 designed as an adapter 19. Figure 4 shows a greatly simplifiedA further embodiment of a system according to the invention is shown schematically in its fixed state in a schematic diagram. The system according to Figure 4 comprises a plurality of vehicles 1, each designed as an e-scooter. The system comprises a station 2 with a stand body 21 that has a zigzag shape. A plurality of housing parts 22 are fixedly mounted on the stand body 21. A first group of vehicles 1 is arranged on a first side of the stand body 21, and a second group of vehicles 1 is arranged on a second side of the stand body 21, wherein the vehicles 1 of each group are arranged next to one another and are held at the station 2 offset from one another along their direction of travel. As a result, their handlebars are also offset from one another along the direction of travel, so that they can overlap perpendicular to the direction of travel. The vehicles of the two groups of vehicles 1 are arranged relative to one another such thata vehicle 1 of the first group and a vehicle 1 of the second group form a pair of vehicles 1, which face each other with their front sides and between which the fixing devices of station 2 are arranged, to which they are each held in a fixed position in the fixing state. The fixing devices of station 2 are formed in this case by the respective housing parts 22 of station 2. From Figure 4 it can be seen that in the embodiment shown, a very space-saving arrangement of a large number of vehicles 1 is possible and these can be fixed in a fixed position at station 2 without interfering with one another. Figure 5 shows a further embodiment of a system according to the invention in a highly simplified schematic representation. The system comprises several stations 2, each having a station battery 25 and a load management device 24. The system further comprises acentral processing unit 3 and a plurality of vehicles 1. Each of the vehicles 1 has an adapter 19 with a wireless communication interface and a location module. The vehicles 1 communicate with the processing unit 3 of the system via the adapter 19. Each of the stations 2 has several fixing devices and several charging devices, so that at each of the stations 2, several vehicles 1 can be held in the fixing state, so that these vehicles are then fixed in position at the station 2 and can be charged via their charging connection by the charging device of the station 2 assigned to them. The load management device 24 of the respective station specifies the charging power that is output via the respective charging devices of the station 2 to the respective charging connection of the vehicle 1 that is assigned to the respective charging device. By means of the load management device 24, each station 2, in particulartaking into account the total charging capacity of their station battery 25, they can control the charging power output by themselves at their charging devices. The computing unit 3 is designed to determine the location of each vehicle 1 via wireless communication with the adapter 19 of the vehicles 1. In the exemplary embodiment shown here, the computing unit 3 records a time-dependent frequency of removal of vehicles 1 fixed in position at the respective stations 2 of the system from the stations 2. Based on this frequency of removal of the vehicles 1 from the respective station 2, or of the use of the vehicles 1 starting from the respective location at which the respective station 2 is located, which frequency is determined by the computing unit 3 itself and stored therein, the computing unit 3 can contribute to a sensible spatial distribution of vehicles 1 and thus generate both ecological and financial added value through the spatial andtime-dependent distribution of vehicles 1 at the stations 2 and by keeping the vehicles 1 ready in a charged state at the stations 2 according to the time-dependent local distribution. This is because the determined frequency can be incorporated into the first and / or second dependency function in such a way that the dependency function depends on the determined frequency, so that the computing unit 3 can specify a specific group of target stations, in particular exactly one target station, depending on the determined frequency of use and thus depending on a time- and location-dependent need for vehicles 1, whereby the user receives a credit when he brings a vehicle 1 to one of the stations 2 of the group of target stations. For this purpose, in the exemplary embodiment shown here, the computing unit 3 is designed to recognize an identification of a mobile terminal 5, in this case a smartphone, which a user 4 carries with him.Upon recognition of such an identification, which is associated with a user account assigned to the user 4, by which a locking device of a vehicle 1 is switched to an enabled state, so that the vehicle 1 can be used by the user 4 as intended using its electric motor, the computing unit 3 records the use of this vehicle 1 by the user 4 with his user account. The user 4 can, associated with his identification, request from the computing unit 3 a target station 2A to which the vehicle 1 is to be brought. In the exemplary embodiment shown here, the vehicle 1, at which the user 4 identifies himself with his mobile device 5, is not parked at any of the stations 2 of the system. In the exemplary embodiment shown here, the computing unit 3 provides the user 4 with information regarding the location details of a specific target station 2A. As soon as the computing unit 3 recognizes that the user 4Vehicle 1 has been brought to the target station 2A so that it is parked at the target station 2A, and furthermore, by means of a corresponding message from the vehicle 1 to the computing unit 3, it is transmitted that the vehicle 1 is ready to charge, i.e., is coupled with a charging connection to a corresponding charging device of the station 2A, the computing unit 3 credits the user account of the user 4 to whom the identification is assigned. As a result of this generally advantageous embodiment according to the invention, a spatially predetermined desired distribution of vehicles 1 at the stations 2 and the keeping of the vehicles 1 at the stations 2 in a charged state can be ensured due to an incentive that is set for the user 4. Figure 6 shows a schematic representation of a system according to the invention, a spatial division of components of the system in a plan view, wherein the system is in aexemplary state. Four stations 2 are shown which are arranged spatially spaced from one another. Furthermore, a target parking location 5 is shown with a first radius 4 encircling this target parking location 5. A vehicle 1 is arranged between the stations 2 and the target parking location 5. In the state of the system shown, the vehicle 1 is not at a station and, in the locked state, is not in the fixed state. Generally preferred according to the invention, the target parking location 5 can be defined as a function of a local event taking place in the first radius 4 or at least in the vicinity of the radius 4, such as a football match, a music festival, or a canceled public transport service. Furthermore, generally preferred according to the invention, the target parking location 5 can also have been defined as a function of weather data and thus, for example, have been selected near a body of water, a beach, or the like.According to the invention, the target parking location 5 can generally be determined particularly preferably by determining a probable high demand for vehicles 1 in the first radius 4, e.g., by a computer model and / or an AI-generated prediction, e.g., based on historical data, wherein the radius definition can be formulated dependently thereon. The radius definition can take into account the fact that at certain times and at certain locations there may be a particularly high demand for vehicles, which should be met regardless of the availability of free spaces at stations. Figures 7 and 8 show, in a schematic representation of a system according to the invention, a spatial division of components of the system in a plan view, wherein the system is in an exemplary state. Three stations 2 are shown, which are arranged spatially spaced from one another. A fourth station 2is defined as target station 3 and the second circumference 6 runs around the center of target station 3. A vehicle 1 is spatially arranged between stations 2 and target station 3. In the illustrated state of the system, vehicle 1 is not located at a station and is in the blocking state, but not in the fixing state. According to the invention, the definition of a station 2 as target station 3 can generally be made depending on whether there are fewer vehicles 1 at this target station 3 than at the other stations 2, other stations 2 are already fully occupied with vehicles 1 and cannot accommodate any further vehicles, or an increased demand for vehicles 1 is expected at this target station 3 and / or in the vicinity of this target station 3 or an increased demand for vehicles 1 is requested by a user. In Figure 8, target station 3 is shown as unusable. According to the invention, a station2 and / or a target station 3 can be defined as unusable if it is determined that station 2 and / or target station 3 is fully occupied with vehicles and / or there is a defect at this station, wherein the radius definition for determining the radius for determining the target parking location is determined depending on this determination. Furthermore, according to the invention, a station 2 that has been identified as unusable can be defined as target station 3, wherein a radius around target station 3 can be defined as target parking location 5.
