Description

  • The invention relates to a device for charging of electric buffers in vehicles with an external electric power dispenser and a vehicle-mounted electrical power receiving device, which is adapted to receive electrical power from the dispenser and to its forwarding to an electrical buffer, wherein the dispensing device and the receiving device have matching contact means. The invention further relates to a method for charging electrical buffers in vehicles.
  • The invention relates to the field of charging of electrical buffers, so car batteries, accumulators and similar, in vehicles, ie in electrically or at least partially electrically powered passenger cars, trucks and possibly two-wheelers, and thus a growing sector of private and public transport.
  • The supply of electric vehicles with the required fuel, ie electric current, is different from the refueling of a fuel-powered motor vehicle, since the refueling of a liquid or gaseous fuel requires a few minutes, while the charging of an electrical buffer may take several hours. This means that a motor vehicle driver with the vehicle parked during the refilling of the cache can not be continuously present. In the private and public sector, unattended recharging of vehicles' electrical buffers is therefore associated with a risk that unauthorized persons may approach the vehicle during recharging and possibly interfere with the recharging process or in view of the high currents required during recharging can injure an electric cache of a motor vehicle.
  • Charging stations for electric vehicles are known. So is in DE 42 13 405 A1 discloses a Stromzapfsäule for charging electric energy collectors of electric vehicles with electric power, which is designed as a classic dispenser for liquid or gaseous fuels and has a supported by a pedestal on a pedestal or stand supported operating unit, in addition to those required for operation Components a connection socket for luminous flux and / or a power outlet is arranged.
  • The electric pump has a fuse of the area near the plug of the vehicle-side connection cable or against arbitrary free hanging from the proper height of the socket assembly. Charging leads from the charging station to the vehicle, where behind the fuel filler flap, an electrical connector is attached.
  • This Stromzapfsäule is an obstacle for a longer and unattended charging time because it is located next to the vehicle and freely accessible and has a lot of space. For private use or for parking spaces that are to be equipped with charging stations, a corresponding Stromzapfsäule is therefore less suitable.
  • These disadvantages are known and are to be solved by inductive charging systems. Inductive charging systems are based on the fact that with an induction coil, a strong alternating electromagnetic field is generated, wherein a motor vehicle has a corresponding induction coil which receives the electromagnetic alternating field. For this purpose, the vehicle is driven reasonably accurately via a charging device, which comprises an electromagnetic coil, which corresponds to a same coil in the vehicle floor. Electric oscillator and amplifier units produce high frequency resonance between coils which then carry energy used to charge an electrical buffer.
  • The inductive method of energy transfer causes high cost of the electronic components and has a relatively low efficiency due to the nature of the electromagnetic radiation used. In addition, it must be ensured that the electromagnetic radiation is kept as low as possible. This is usually not the case, since the ground clearance of a vehicle always requires a large air gap to the ground and to the stationary coil of energy transfer.
  • It is an object of the present invention to enable charging of electric buffers in vehicles which is safe both for the vehicle and for persons, has a high efficiency and is large in both the private and the public sector Scale can be used.
  • This object is achieved by a device for charging cassettes in vehicles, having an external electric power supply device and a vehicle-mounted electrical power receiving device, which are designed to receive electric power from the output device and to forward it to an electrical buffer wherein the dispenser and the receiving device comprise mating contact means further developed by placing the dispenser in or on the ground such that a vehicle with a receiving device can be placed over it, the dispenser and / or the receiving device being a movable positioning device comprises, by means of which, after a parking of the vehicle on the dispenser, a contact means on the positioning device from a non-loading position can be brought into a loading position in which the mating contact means are in contact.
  • If the contact means are in contact with each other, this means according to the invention that a charging current from the dispenser to the receiving device is transferable. According to the invention, it is also included in that a consumption stream from the buffer store can be retransmitted via the receiving device to the delivery device and, if appropriate, can be fed into a public power grid. This ensures that the device according to the invention for charging electrical buffers in vehicles can also be used for use in an intelligent power grid, in which end consumers such as car batteries are used as temporary storage for temporarily excessively produced energy, which is later retrievable in times of lower power production.
  • The invention is based on the basic idea that the dispensing station is arranged down-to-earth and a vehicle is parked above the dispensing station. A connection or contact means of a receiving device on the vehicle is arranged on the vehicle floor. Accurate positioning of the vehicle over the dispenser is not necessary because either the dispenser or the receiving device or both have a positioning device with which automatically the mating contact means of the dispenser and the receiving device are moved toward each other.
  • The positioning device is preferably driven in a hydraulic, pneumatic or electromotive manner.
  • The solution according to the invention has the further advantage that the space requirement of the device according to the invention does not exceed the space requirement of a vehicle, so that even conventional parking spaces can be equipped, for example, with devices according to the invention at each parking space without the parking capacity of the parking space decreasing. In addition, by the arrangement under the vehicle floor abuse and a risk of accidents encountered effectively. In the device according to the invention, the security against unauthorized intervention and the risk of injury can be minimized by a suitable selection of secure contact means, shielded and lockable plugs or the like.
  • The dispensing device and / or the receiving device preferably comprises at least one sensor by means of which the relative position of the dispensing device relative to the receiving device and / or the matching contact means relative to one another can be determined. The sensor signals serve to determine the position and are thus suitable for the automatic positioning of the devices or contact means. In particular, they are also usable for coarse positioning of the vehicle relative to the dispensing device. Suitable sensors are optical sensors or electromagnetic bearing sensors by means of triangulation bearings, inductive food sensors and the like.
  • In an advantageous embodiment, the positioning device comprises a telescopic arm rotatable about a vertical axis with a variable length relative to the vertical axis of rotation, wherein the contact means is arranged on the extendable part of the telescopic arm. The rotation about the vertical axis and the change of the length of the telescopic arm make it possible to change the position of the contact means arranged thereon in a large area by corresponding rotational and translational movements. The contact means may preferably be arranged on a further, vertically extendable telescopic arm or a folding arm which can be folded into a vertical position.
  • In an alternative advantageous embodiment, the positioning device is designed as a disk rotatable about a vertical axis, which has a guide slot extending in the radial direction, in which the contact means is arranged to be radially displaceable relative to the vertical axis. Also in this embodiment according to the invention a rotational and translational movement can be combined in order to position the contact means correctly. The contact means is then moved vertically in the direction of the appropriate contact means of the other device and contacted.
  • Alternatively, the positioning device is preferably also designed as an X-Y displacement device, i. H. it is translationally movable in two mutually orthogonal directions.
  • In all embodiments, the positioning device is formed flat so that when parking a vehicle over the dispenser, the positioning device is not damaged. Therefore, the contact means is preferably vertical slidably disposed on the positioning device or of the positioning device opposite device, so the dispenser or the receiving device, so that the mating contact means are contacted with each other.
  • The contact means are preferably designed as plug contacts for an electrically conductive connection. This allows a low-resistance efficient charging of the cache.
  • Alternatively, it is also preferably provided that the contact means are formed as induction coils for an inductive transmission of electric current. Also in this case, the induction coils are moved towards each other by means of the positioning device. This has the advantage that the air gap between the induction coils is very small, whereby the inductive energy transfer gains in efficiency and emissions to the outside are reduced.
  • Preferably, in this case, the at least one sensor, by means of which the relative position of the dispensing device to the receiving device and / or the mating contact means, ie the induction coils, can be determined relative to one another, is designed as an induction coil or as an inductive proximity sensor. With this measure, the respective opposite device is very accurately locatable.
  • In an advantageous development, the dispensing device and the receiving device each have a housing part, which are mutually suitably designed so that when producing a contact between the contact means, ie the induction coils, a composite housing is formed, which at least substantially prevents leakage of alternating electromagnetic fields , A corresponding dispensing device can be recessed in the floor and have a half-casing which ends upwards, ie towards the floor surface, so that a metallic border can be seen on the floor.
  • The housing part of the receiving device is positioned by means of a positioning device in this case on the dispenser and lowered, the housing part is formed downwardly open and coincides in its cross-sectional shape at the bottom with the cross-sectional shape of the upper edge of the housing part of the dispenser, so that the two housing parts as possible or essentially seamlessly fit each other and be placed on top of each other. It is also possible that the upper housing part of the receiving device comprises the lower housing part of the dispenser, so that an even denser housing closure is generated, and electromagnetic alternating fields are enclosed even more efficiently within the assembled housing.
  • Preferably, a communication connection between the dispensing device and the receiving device can be produced, by means of which, in particular, data about the vehicle and / or the intermediate store can be transmitted to the dispensing device. Also data on the network side information, so for example, electricity prices, available amounts of electricity, identification data of the dispenser, etc. can be transmitted via such a communication connection.
  • To further simplify the operability is preferably provided that the receiving device is connected to an optical and / or acoustic display device in the vehicle and to a visual and / or audible indication of a relative position between the dispenser and the receiving device and / or a positioning of the vehicle Dispensing device and / or for contacting the contact means of the dispensing device and the receiving device is formed.
  • In this way, it is possible for the vehicle driver to first position the vehicle via the dispensing device with the aid of the acoustic and / or visual displays in such a way that it is possible to make contact with the mutually compatible contact means and then to monitor that the positioning of the contact means relative to one another and / or or a contacting of the contact means with each other is done correctly, so that a charging process can begin or can be initiated. The corresponding signals can be formed similarly as in known parking aids, wherein, for example, an approach to the dispenser with a faster becoming acoustic signal sequence can be displayed or by means of a graphical display that makes the relative position graphically visible.
  • To secure the charging process and the vehicle is preferably provided that the receiving device is connected to an on-board electronics of the vehicle and is designed to prevent the vehicle from driving away when the receiving station is connected to the discharge station. In this way, the vehicle is prevented from being moved during the charging process, as a result of which the vehicle and the delivery device can be damaged and a dangerous situation created for humans and animals. Alternatively, it is provided that a charging process can only begin when the vehicle is completely parked. A release of the brake would in this case lead to the charging process is interrupted and the contact means are decoupled and removed from each other.
  • The object underlying the invention is also achieved by a method for charging vehicle electrical buffers, in particular by means of a device according to the invention described above, wherein an external electric current dispenser and a vehicle-mounted electrical power receiving device adapted to receive electric power is provided by the dispensing device and for its transmission to an electrical buffer, wherein the dispensing device and the receiving device have mating contact means, the dispensing device and / or the receiving device comprising a movable positioning device, comprising the following method steps:
    • a) the vehicle is driven over the discharge device arranged in or on the ground and parked in a position in which a contacting of the mating contact means is possible,
    • b) after the vehicle has been parked over the dispenser, a contact means on the positioning device is brought from a non-loading position to a loading position in which the mating contact means are in contact with each other,
    • c) electrical power is passed from the dispenser via the receiving device to the buffer.
  • According to the invention, the vehicle driver thus roughly controls his vehicle via the loading device, wherein a spatial tolerance of up to one meter, depending on the embodiment, is conceivable, for example. If the vehicle is parked, the contact means of the dispenser and the receiving device are moved towards each other and contacted with each other, so that the charging process can be initiated.
  • Advantageously, after the process step c) in a subsequent process step d) after complete or partial charging of the buffer, the loading is terminated, the connection between the contact means is interrupted and the contact means is moved to the positioning device in the non-loading position. Thus, the vehicle is fully or partially charged and ready to be started and driven away.
  • Preferably, the positioning and contacting in step b) is done automatically on the basis of signals from at least one sensor, by means of which the relative position of the dispenser to the receiving device and / or the mating contact means is determined to each other. On the basis of the sensor data, optical or acoustic aids in the vehicle can tell whether the vehicle is in the area of the charging device and whether there is a successful approach and contacting of the contact means of the delivery device and the receiving device.
  • Preferably, the vehicle is secured against changes in position and / or driving away before carrying out the method step b). This promotes sabotage safety and operational safety.
  • Since the driver and possibly other persons get on and off, the device is advantageously designed to be flexible to a sufficient degree, so that the contact and the integrity of the dispenser and the receiving device are not affected.
  • If the method steps b) and c) are preferably carried out only after leaving the vehicle and closing it, in particular by means of a remote control, the method can be carried out particularly reliably. Further preferably, the contact means and / or the positioning device are promptly and automatically brought into the non-loading position when the vehicle, in particular by means of a remote control, is opened.
  • All mentioned features, properties and advantages of the subject invention, d. H. the device according to the invention and the method according to the invention, without limitation apply to the respective other subject matter of the invention.
