Description

The following invention relates to a combined parking and charging device for an electric or hybrid vehicle.

The DE 20 2009 000 259 U1 describes a conventional charging device for an electric or hybrid vehicle, which is equipped with at least one charging station, which has at least one charging contact, which is connectable to a complementary charging contact of a vehicle to be charged, so as to cause the charging of a vehicle-own electrical energy storage. The thereby coming between charging station and aufzuladendem vehicle charging contact can be designed galvanic or inductive. A charging contact between the vehicle and the charging station, in particular, can be produced by automatically extending the charging contacts of the vehicle when the charging station is reached and by connecting them functionally to the charging contacts of the charging station. The charging contact with the vehicle can also be made automatically by sensor-controlled robotic contacting by the charging station. In this case, the charging contact of the vehicle is detected by sensors and actuated kinematics for contacting accordingly.

It is an object of the present invention to provide an improved embodiment for a combined parking or charging device for an electric or hybrid vehicle.

The above object is achieved by a device according to the independent claim 1. Preferred embodiments are subject of the dependent claims.

The combined parking and charging device according to the invention comprises at least one receiving unit for receiving the electric or hybrid vehicle. Such a receiving unit allows a driver of the electric or hybrid vehicle, this space-saving, for example for parking purposes, turn off in the receiving unit, the electric or hybrid vehicle can be supplied in such a parked state with electrical energy to an electrical energy storage of the electric or hybrid vehicle, for example in the form of a conventional rechargeable battery. This is done by means of a charging unit provided in the receiving unit. In this way, it can be achieved that after completion of the shutdown process, a fully-charged electrical energy store is available for the further driving operation of the electric or hybrid vehicle. Ideally, the electrical energy store is completely charged during the shutdown process in the receiving unit. However, it is clear in this context that the charging of the electrical energy storage takes depending on state of charge when receiving the electric or hybrid vehicle in the receiving unit or in dependence on the electrical capacity of the electrical energy storage a certain period of time. Of course, the electric or hybrid vehicle accommodated in the receiving unit can also be removed from the receiving unit at any time before the charging process is completed. In this case, of course, then not the maximum in the electrical energy storage recordable electrical energy for operating the electric or hybrid vehicle is available.

The receiving unit may be designed in the manner of a simple so-called parking box, the volume of which is ideally just sufficiently large to accommodate the vehicle to be parked in it. In this case, the parking box can be optimized in terms of their size for receiving a specific vehicle type (for example, a compact or small car).

The storage or charging device may preferably include a supply device for automatically moving the electric or hybrid vehicle into a parking position located within the receiving unit, in which the electric or hybrid vehicle can then be charged by means of the charging unit. This allows a driver of the vehicle to leave it before parking in the receiving and charging device, so that after leaving the vehicle, the feeding device can automatically move the vehicle to the parking position. Then it is also not necessary to design the receiving unit in terms of their volume much larger than the male vehicle, since the driver of the vehicle this yes does not have to move manually to the parking position and consequently can leave this only after completion of the shutdown. In particular, therefore, an additional spatial area, for example in the region of a vehicle door of the vehicle, does not necessarily have to be provided in the receiving unit, which would allow the driver of the vehicle to comfortably leave his vehicle. Consequently, by means of the provision of a feed device, the receiving unit according to the invention can be made spatially compact and thus very space-saving.

The supply device may in this case comprise a supply control device which may be in operative connection with a complementary vehicle control device provided in the electric or hybrid vehicle, so that the electric or hybrid vehicle is moving can be virtually "remotely controlled" within or to the receiving unit by means of the first control unit.

In a particularly preferred embodiment, the technical realization of the operative connection between the first control unit and the vehicle control unit by wireless transmission means such as WLAN, Bluetooth, IR, GSM and / or radio remote control done.

Furthermore, the supply device can have at least one sensor unit for supporting the movement of the electric or hybrid vehicle. By way of example, such a sensor or actuator unit may be a position sensor which can supply information about the instantaneous vehicle position of the electric or hybrid vehicle within or outside the recording unit and / or transmits it to the first control unit.

Furthermore, in a further embodiment, the feed control unit may be designed such that it is in operative connection with vehicle assistance systems of the electric or hybrid vehicle, for example an ultrasonic sensor system and / or a radar sensor system, by means of the vehicle control unit that the information provided by these sensor systems (eg with regard to the instantaneous position of the vehicle or with respect to obstacles arranged in a surrounding area around the vehicle) can be used.

In a particularly preferred embodiment, the combined parking and charging device may be configured such that the driver of the vehicle leaves the vehicle for parking at a predetermined transfer point, so that the vehicle is then moved in an automated manner from the supply device to the parking position within the receiving unit.

In a preferred embodiment, the charging unit can be brought into operative connection by means of inductive or conductive coupling with the electric or hybrid vehicle arranged in the parking position for charging the energy store. Particularly preferred is an arrangement in which the coupling between the charging unit and the electric or hybrid vehicle in a front region of the electric or hybrid vehicle, in particular in a region in which a license plate of the electric or hybrid vehicle is arranged takes place. The conductive coupling can be realized in the form of conventional electrical contacts in the manner of a key-lock principle. The conductive coupling can be achieved, for example, in that electrical contacts arranged on the vehicle and on the charging unit interlock as soon as the vehicle is in the parking position.

Alternatively or additionally, an electrical contact arranged on the charging unit can also be moved automatically to the complementary electrical contact arranged on the vehicle, in particular precisely when a triggering event, for example reaching the parking position by the electric or hybrid vehicle, has taken place ,

In the case of inductive coupling, the charging unit is equipped with an inductive coupling element, for example in the form of an induction coil; the corresponding applies then in a complementary manner for the electric or hybrid vehicle, so that by means of the inductive coupling, the energy transfer can be done wirelessly.

The charging unit itself may have electrical transmission means suitable for both inductive and conductive coupling, for example conventional electrical cables, by means of which electrical energy can be transmitted.

Now, in a further embodiment, the parking and charging device can also have at least one energy supply system for providing electrical energy. Such an energy delivery system may, for example, be solar cell-based, which system may then comprise solar cell panels, which are preferably arranged outside the combined storage and charging device) such that they contain the radiation energy contained in the light impinging upon them convert into electrical energy. The charger may then be electrically connected to the energy delivery system such that the electrical energy provided by the energy delivery system may be transferred to the electric or hybrid vehicle to be charged.

Of course, various variants are conceivable in the concrete technical design of the energy supply system. For example, it may be thought that the energy-providing system has an electrical buffer in which electrical energy can be cached when no electric or hybrid vehicle is in the receiving unit. In this case, the electrical energy gained by the solar cell system or if necessary, can be temporarily stored until it is actually required for charging an electric or hybrid vehicle.

In this way it can be ensured that the electrical energy generated by the energy supply system does not have to be used immediately for charging the electric or hybrid vehicle, which significantly improves the flexibility of the combined parking and charging device according to the invention, in particular with regard to its energy management. Accordingly, electrical energy can be retrieved from the cache when an electric or hybrid vehicle to be charged, although not enough electrical energy can be generated by the solar cell system. In particular, charging of the electric or hybrid vehicle can be ensured even in the dark by using an intermediate store.

Furthermore, the energy supply system may alternatively or additionally be coupled to a conventional electrical power network, from which, if necessary, electrical energy can be obtained. In a variant, it may also be conceivable to feed electrical energy generated by means of the energy supply system into such an electrical power grid when this electrical energy is not needed for charging the electric or hybrid vehicle.

Advantageously, the storage and charging device may comprise a plurality of receiving units for receiving a plurality of electric or hybrid vehicles. With regard to the specific training or spatial arrangement of such a plurality of recording units, a variety of variants are conceivable. For example, such a parking and charging device may be in the form of a so-called maneuver parking garage, a rondel or a tunnel. In particular, it may be thought that the plurality of receiving units is arranged in the manner of a two-dimensional grid to each other, which allows a particularly compact and thus space-saving arrangement of the combined parking and charging device according to the invention. This allows the use of the combined parking and charging especially in areas where the available space is limited and should therefore be used very effectively, which is often the case for example in city centers or urban centers.

In a particularly preferred embodiment, it may be contemplated that the energy delivery system is disposed in a roof area of the combined storage and charging device.

In a further preferred embodiment, the plurality of receiving units in the manner of a so-called paternoster system may be formed, by means of which either a certain one of the plurality of receiving units is movable to a feed position in which the electric or hybrid vehicle by means of the feeding device as described above the parking position of the particular receiving unit can be moved.

Other important features and advantages of the invention will become apparent from the dependent claims, from the drawings and from the associated figure description with reference to the drawings.

It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.

Preferred embodiments of the invention are illustrated in the drawings and will be described in more detail in the following description, wherein like reference numerals refer to the same or similar or functionally identical components.

Show, in each case schematically,

1 An embodiment of the combined storage and charging device according to the invention,

2 a variant of 1 in which the combined storage and charging device is designed as a so-called paternoster system,

3 another variant of 1 in which the combined storage and charging device is designed as a so-called high-transverse storage module.

In the 1 is a combined parking and charging device according to the invention for an electric or hybrid vehicle 3 (hereinafter referred to as "vehicle") represented and with 1 designated. The combined storage and charging device 1 has a plurality of receiving units 2 for picking up the vehicle 3 on, in the illustration according to the 1 exemplarily three such recording units 2 are shown. It is clear that in variants also a different number of recording units 2 is possible. Each of the recording units 2 can a vehicle 3 , for example, for parking purposes, record, in such a parked state at the same time an electrical energy storage 4 the vehicle 3 can be charged.

In the presentation of the 1 are the vehicles 3 in the respective recording unit 2 arranged in a so-called parking position P. In the Parking position P is the electrical energy storage 4 of the vehicle 3 Chargeable with electrical energy. This is the parked in the parking position P vehicle 3 with the charging device 5 in active connection. Preferably, this active compound is technically realized as a conductive or inductive coupling.

In the 1 is exemplarily a conductive coupling between the charging device 5 and the vehicle 3 (see upper and lower of the three receiving units 2 ), preferably in a front area of the vehicle 3 For example, in an area where a license plate of the vehicle 3 is arranged takes place. However, it is clear that in variants the conductive (and also the inductive) coupling basically also in another area of the vehicle 3 can be done.

The in the 1 shown conductive coupling is realized such that between on the vehicle 3 arranged electrical contacts 6 and correspondingly complementary electrical contacts 7 the charger 5 an electrical contact is made. The electrical contacts 6 of the vehicle 3 are also with the electrical energy storage 4 of the vehicle 3 electrically connected, and the complementary electrical contacts 7 the charger 5 are with an electric power supply system to be explained below 8th the combined storage and charging device 1 electrically connected to the vehicle 3 provides supplied electrical energy.

In an alternative variant, it can now also be thought that the complementary electrical contact 7 the charger 5 For example, after taking a triggering event such. B. moving the vehicle 3 in the parking position P, automated to the electrical contact 6 of the vehicle 3 is moved and in this way an electrical contact is made. With regard to the concrete technical realization of the electrical contact formation, in principle numerous technical implementation options are conceivable.

In a further alternative variant, instead of the conductive coupling, an inductive coupling by means of suitable inductive elements, for example suitable induction coils, is also conceivable (see the middle of the three recording units) 2 in the 1 ). For this it is not necessary that a precise mechanical coupling for making an electrical contact between vehicle 3 and charging device 5 what must be done is the flexibility of the combined storage and charging device 1 , in particular with regard to a precise positioning of the vehicle 3 in the recording unit 2 , can increase significantly.

The energy delivery system 8th may comprise a solar cell system, which may comprise suitable solar cell panels, preferably outside the combined storage and charging device 1 are arranged to convert radiant energy contained in the (solar) light impinging thereon into electrical energy, so that they are responsible for the charging of the electrical energy store 4 is available.

Also regarding the technical design of the energy supply system 8th In principle, many variants are conceivable. In particular, the energy delivery system 8th an electrical buffer 9 , for example in the form of a rechargeable battery. In the electrical buffer 9 can then be cached by means of the solar cell system electrical energy, if not just to charge the electrical energy storage 4 one in the receiving unit 2 parked vehicle 3 is needed. Accordingly, by means of the in the electrical buffer 9 cached electrical energy even then a charge of vehicles 3 in the recording unit 2 be performed when - for example, due to insufficient sunlight - from the solar cell system temporarily insufficient electrical energy can be generated. By using an electrical buffer 9 in conjunction with the energy delivery system 8th can the energy management of the combined storage and charging device 1 be significantly improved.

In an improved variant, the energy delivery system 8th alternatively or additionally with an external electrical power network 17 be connected, allowing electrical energy to charge the vehicle 3 also from the electrical mains 17 and can also be fed into this.

To a shutdown of the vehicle 3 in the recording unit 2 In the most effective and especially time-saving manner to perform, the combined parking and charging device 1 also a feeder 10 for automatically moving the vehicle 3 in the parking position P include. In this case, it is not necessary for a driver of the vehicle 3 This must be positioned manually in the parking position P, but this already before the actual shutdown in the receiving unit 2 can leave.

In this way, the recording unit 2 be optimized in terms of their volume, since the recording unit 2 from a driver of the vehicle 3 for parking the vehicle 3 does not have to be entered. Thus, it is not necessarily required, an additional spatial area within the recording unit 2 to provide which a driver of the vehicle 3 leaving the vehicle 3 allows. In particular, it is not necessary in this case, such a spatial area in the region of the vehicle door of the vehicle 3 provided.

For the technical realization of the feeding device 10 Many design options are conceivable. On the one hand, the feed device 10 a sensor unit 12 comprising, by means of which information about the current vehicle position of the vehicle 3 within an access area 11 or within the recording unit 2 can be delivered. For this purpose, the sensor unit 12 from a controller 13 the feeding device 10 be controlled and read out. Based on that of the controller 13 Information read out can be the vehicle 3 then be driven and moved accordingly.

For this purpose, it is conceivable that the of the control device 13 obtained information regarding the current vehicle position to the vehicle 3 transmitted and from one to the controller 13 complementary control device 14 of the vehicle 3 be used, wherein the control device 14 a drive system of the vehicle 3 drives (not shown). In a particularly preferred variant, by means of the control devices 13 . 14 a coupled remote control of an electric motor and an electric steering of the vehicle 3 be realized.

Should that be in the recording unit 2 parked vehicle 3 again from the combined storage and charging device 1 can be removed, so removing the vehicle 3 also by means of the feeder 10 carried out, with the above explanations to the automated parking of the vehicle 3 Mutatis mutandis are applicable.

This coupling between the controller 13 the feeding device 10 and the controller 14 of the vehicle 3 can technically be realized in various ways, in particular using known wireless transmission technologies such. B. WLAN, Bluetooth, IR, GSM or "Radio Remote Control".

In particular, if present, in the vehicle 3 existing driver assistance systems such. As parking sensors, which are preferably based on radar or ultrasonic sensor systems, the automated parking of the vehicle 3 be used.

In a further development variant, it is also conceivable that a driver of the vehicle 3 is informed about the shutdown, for example, by wireless transmission of appropriate information to a smartphone 16 or a comparable electronic device. Alternatively or additionally, such information can also be provided on the Internet.

An essential fundamental advantage of the combined storage and charging device 1 It also exists in that the vehicle 3 within the recording unit 2 Protected against external influences can be turned off, such external influences may be particularly weather influences. The combined storage and charging device 1 But also offers protection from damage due to vandalism.

In a further developing variant can now also the energy supply system 8th and / or the electrical cache 9 with a suitable control device 15 be equipped, which improved energy management of the energy delivery system 8th or the cache 9 with the vehicles to be charged 3 allows. For example, variants are conceivable according to which of the driver of the vehicle 3 a desired amount of electrical energy with which the vehicle 3 should be charged to the controller 15 be transmitted.

It is also conceivable that by communication with the control device 15 From the driver information about the state of charge of the vehicle 3 , in particular with regard to current range, energy price, etc. can be queried. Accordingly, alternatively or additionally, it may also be thought that information regarding a desired shutdown period (= parking duration) of the vehicle 3 between the driver and the combined parking and charging device 1 can be communicated. Furthermore, it may be thought that information about already incurred or still to be incurred parking costs when parking the vehicle 3 be communicated. Appropriate interactions with the driver of the vehicle 3 may alternatively or in addition to the above-described variant using a smartphone 16 also via an Internet-based information system.

In a further development variant, it is conceivable that the driver of the vehicle 3 a reservation of a recording unit 2 can be done, preferably again using a smartphone 16 (or a comparable electronic Device) and / or by reservation via a suitable internet reservation system. Furthermore, it may be thought that in an improved variant, information on an occupancy status of the combined storage and charging device 1 available on the internet or via smartphone 16 are available.

Regarding the spatial arrangement of the different recording units 2 within the combined storage and charging device 1 Many variants are conceivable. For example, the inventive combined storage and charging device 1 in the form of a so-called paternoster system 18 be formed, which in the representation of the 2 is shown schematically.

The 2 shows schematically how such a paternoster system 18 with a plurality of receiving units 2 can be realized. By means of the paternoster system 18 can be a specific recording unit 2 in the 2 additionally with the reference number 19 is provided for receiving a vehicle 3 by means of the mobile paternoster system 18 to the feeder 10 be moved so that the vehicle 3 automated into the recording unit 19 can be moved.

Alternative to the paternoster system 18 are also numerous other variants, for example in the form of a in the 3 schematically illustrated high-transverse memory module 20 , possible. In such an embodiment, the plurality of receiving devices 2 be arranged in the manner of a two-dimensional grid, resulting in a particularly compact and thus space-saving construction of the combined storage and receiving device 1 allows. In this case it makes sense to use the feeding device 10 movable so that these (as with the arrows 21 indicated) to the respective recording unit 2 can be moved in which the vehicle 3 should be turned off. Instead of in the 3 illustrated arrangement of the recording units 2 in the manner of a two-dimensional field, a variety of other arrangement variants, for example in the form of a roundel or a tunnel, are conceivable. A combination of such variants is conceivable.

Regarding the concrete technical realization of the feeding device 10 are also various design variants conceivable. In particular, it is conceivable in a further development variant, the realizations of in the 2 shown paternoster system 18 with the in the 3 shown high-transverse memory module 20 to combine.
