Description

The present invention relates to a charging coupler system with a charging coupling and a charging negative coupling for establishing an electrically conductive connection of a storage module for electrical energy of a consumer, in particular in a motor vehicle, with an energy supply unit for providing electrical energy. The invention further relates to a method for producing an electrically conductive connection and a motor vehicle with a charging negative feedback.

Systems for coupling storage modules for electrical energy in a motor vehicle with a power supply unit for providing electrical energy are known. The systems enable an automated coupling of a consumer, in particular a motor vehicle, to a charging infrastructure. The systems offer a different degree of automation for coupling the memory modules of a motor vehicle to a power supply unit. A higher degree of automation in the production of an electrically conductive connection represents an increased level of comfort for a user.

A charging system from the DE 10 2012 014 936 A1 , which generates a coupling with a mating connector for charging an electrical energy store of a motor vehicle with a robot-guided plug. The robot-guided connector is aligned and coupled to the mating connector by means of a position detection device and a force detection device.

Next is from the DE 10 2009 006 982 A1 a charging system of an energy source of a means of transport is known which can automatically establish a coupling of the charging device with the means of transport. The movable device of the loading device is also guided with a robot unit. A detector unit recognizes their position on the basis of optical features of the interfaces and thus supports the coupling process.

From the DE 10 2009 015 753 A1 again a parking space with an integrated charging function for a motor vehicle is known. There an arrangement of an energy transmission device in the floor of the parking lot is disclosed. From there, the device can automatically establish a coupling between the supply unit and the motor vehicle. In order to detect deviations in the position of the parked motor vehicle, the invention uses a sensor for detecting the position and the energy transmission unit can be moved at least within a predetermined adjustment range.

A disadvantage of the known solutions is that the sensors for position detection of the coupling halves are prone to errors due to interference. Optical sensors, in particular cameras, for position detection can be negatively influenced by ambient light and generate incorrect or no position detections and thus prevent successful coupling.

It is therefore the object of the present invention to eliminate or at least partially eliminate the disadvantages of the devices for the coupling process of a consumer, in particular an electrically operated motor vehicle, with a power supply unit. In particular, it is the object of the present invention to provide a charging coupler system for producing an electrically conductive connection of a storage module for electrical energy in a motor vehicle with a power supply unit, a method for producing an electrically conductive connection for a storage module for electrical energy in a motor vehicle with a power supply unit to provide electrical energy by means of a charging coupler system and a motor vehicle with a charging counter coupling of a charging coupler system, which enable a consumer, in particular an electrically operated motor vehicle, to be coupled with a power supply unit in a simple manner, which is less prone to errors, reliable and cost-effective.

The above object is solved by the claims. Accordingly, the object is achieved by a charging coupler system having the features of claim 1, by a method for establishing an electrically conductive connection by means of a charging coupler system according to the first aspect according to claim 7, and by a motor vehicle with a charging counter coupling of a charging coupler system having the features according to claim 10. Further features and details of the invention emerge from the subclaims, the description and the drawings. Features and details that are described in connection with the charging coupler system according to the invention apply, of course, also in connection with the method according to the invention and the motor vehicle according to the invention and vice versa, so that with respect to the disclosure of the individual aspects of the invention, reference is always or can be made to one another.

According to the first aspect of the invention, the object is achieved by a charging coupler system for establishing an electrically conductive connection of a storage module for electrical energy in a motor vehicle with an energy supply unit for providing electrical energy solved. The charging coupler system has a charging coupling and a charging counter coupling, the charging coupling and the charging counter coupling being configured in a coupling state for the transmission of electrical energy. The charging coupler system also has a movable holding device and a computer unit, the holding device being designed to hold the charging coupling and the computer unit being designed to regulate the movement of the holding device. The charging coupler system furthermore has a receiving device for receiving data, the receiving device being connected to the computer unit for data communication, the charging coupler system having a transmitting device for actively transmitting data and the computing unit being designed to move the data based on the data received by the receiving device To regulate the holding device in such a way that the charging coupling and the charging negative coupling establish an electrically conductive connection.

A storage module for electrical energy is to be understood in the sense of the invention as, for example, an accumulator, in particular for use in a motor vehicle as a traction battery. In the context of the invention, a movable holding device can be a robot arm with at least two degrees of freedom, a guide device, a pneumatic and / or hydraulic system or a combination of the elements mentioned. Holding the charging coupling in the holding device can be carried out with various fastening options. The holding can be made detachable by means of screws, clamps and / or other fastening means or it can also be made non-detachable by means of material connections. A charging coupling and a charging negative coupling preferably represent a male and a female version of a plug connection. A computer unit can be any form of power unit for executing program code and can have different wireless or wired input and output connections for receiving and issuing data and commands. Within the scope of the invention, a receiving device represents a device for receiving data. Data can be signals, in particular light waves of the visible or invisible wave spectrum. The receiving device can be arranged on the holding device or on the charging coupling. However, the receiving device can also be arranged at a distance from the holding device in the room. A transmitting device represents a device for the active transmission of data. For example, a transmitting device can be a diode, in particular an LED. However, the transmitting device can also send acoustic or other data. An active transmission of data differs from a passive transmission of data in that not only light waves are reflected, for example, but that the intensity, the sequence and the speed and other features of the transmitted data can be influenced. The transmitting device can be arranged on the charging coupling or in the vicinity of the charging coupling or at a distance from it. The components of the charging coupler system can be housed together or individually in housings. The components can also be arranged together in a small installation space or at a distance from one another in space and can be connected to one another in a data-communicating manner with corresponding wireless or wired connections.

Within the scope of the invention, the charging coupling and the receiving device are assigned to the energy supply unit, and the charging counter coupling and the transmitting device are assigned to the consumer, here the storage module for electrical energy in a motor vehicle. However, it is evidently clear that a reversal of this assignment, that is to say that the charging coupling and the receiving device on the side of the storage module and the charging counter coupling and the transmitting device on the side of the energy supply unit, have the same technical effect and also part by means of kinematic reversal of the invention.

A charging coupler system according to the first aspect is particularly advantageous due to the presence of a transmission device for the active transmission of data. Due to the above-mentioned possibilities of influencing a transmission device on the intensity, the sequence and the speed and other features of the transmitted data, the susceptibility of the position detection by the receiving device in connection with the computer unit can be reduced or even excluded. Interferences such as light and shadow, reflections, too low or too high lighting conditions have a significantly reduced or even no influence on the data reception according to the invention for detecting the position of the charging coupling or the charging counter coupling. The receiving device can thus perform the data reception for position detection in a significantly more reliable and error-free manner. The result of this is that a charging coupler system designed in this way thus enables a consumer, in particular an electrically operated motor vehicle, to be connected to an energy supply unit in a simple manner, which is less prone to errors, reliable and inexpensive.

According to a preferred further development of the invention, it can be provided in a charging coupler system that the transmitting device is designed as a light-emitting diode and the receiving device as an optical sensor. A light emitting diode is a particularly advantageous transmission device because it low cost and long life. Furthermore, a light-emitting diode can be specifically selected for its emitted lightwave spectrum and emit different lightwave spectra for different applications as required. Cameras, diodes or other optical sensors can be used as optical sensors.

A charging coupler system designed in this way enables an advantageously reliable data reception for determining the position of a charging negative coupling, in particular on a motor vehicle, with a light diode as the transmitting device.

According to a further preferred development of the invention, it can be provided in a charging coupler system that the transmitting device is designed to transmit a predefined data sequence, in particular a unambiguous data sequence, preferably a repeated data sequence. For the coupling process between the memory module of a motor vehicle and a power supply unit, it is advantageous if the data exchange between the transmitting device and the receiving device is as free as possible from interference or if interference has the least possible influence on the function of the devices. A predefined, in particular a unambiguous, data sequence enables improved data reception with less susceptibility to errors between the transmitting device and the receiving device. A pairing between a transmitting device of a motor vehicle and a receiving device of a power supply unit is described as an example. The sending device actively sends out a predefined data sequence which is received by the receiving device. Consequently, a position determination and ultimately a coupling of the charging coupling with the charging counter coupling for the transmission of electrical energy is generated by means of the movable holding device and the computer unit. An unambiguous data sequence actively transmitted by the transmission device additionally enables no further vehicles or their transmission devices to disrupt the coupling process. A repetition of the transmitted data sequence enables a greater time tolerance for the data reception and the position determination and the coupling process and prevents the transmission of the data sequence from having to be restarted due to the premature termination of the transmission.

According to a likewise preferred further development of the invention, it can be provided in a charging coupler system that a charging coupling is designed as a pin, in particular a plug, and the charging negative coupling is designed as a sleeve, in particular a socket. The design as a plug and socket is a common constructive design of charging systems in electrically operated motor vehicles. This design represents a tried and tested design of the charging coupling halves, but other configurations, for example rotary or magnetic locks or combinations of these, are also possible and conceivable for the charging coupler system according to the invention. Furthermore, a large number of the designs mentioned can be used, such as a plug with 7 contacts and a socket with 7 sleeves. A large number of contacts and sleeves can be manufactured inexpensively and enables efficient power transmission during the charging process and avoids temperature problems.

According to a likewise preferred further development of the invention, it can be provided in a charging coupler system that the computer unit has a position determining unit which is designed to regulate the movement of the holding device as a function of the position of the transmitting device and the relative position of the charging negative coupling to the position of the transmitting device. A charging coupler system designed in this way with a position determining unit advantageously enables the transmitting device and the charging negative coupling to be arranged independently of one another. This results in an advantageous great freedom in the design and constructive design of the elements of the charging coupler system. A computer unit can consequently enable the coupling of charging coupling and charging counter coupling by means of a position determination unit, irrespective of where the transmitting device is arranged on, for example, a motor vehicle. For example, this is made possible by a stored relative position of the charging negative coupling to the transmission device.

According to a particularly preferred further development of the invention, it can be provided in a charging coupler system that a sensor device is arranged on the charging counter coupling or in the vicinity of the charging counter coupling, which is designed to actively transmit data by the transmitting device when the holding device approaches the charging counter coupling to initialize. A correspondingly designed charging coupler system has the advantage that an active transmission of data by the transmitting device is only initiated when the holding device is approached. It is also possible to define further criteria for the transmission of data by the sending device. For example, an open flap of the charging counter coupling of the memory module of a motor vehicle can be a prerequisite for the transmission of data. Energy can thus be saved by preventing data from being sent out permanently. In the case of electrically powered vehicles, the current time The saving of energy can be seen as one of the most important aspects of the design, since this directly gains range for the vehicle.

• - Herstellen der elektrisch leitenden Verbindung der Ladekopplung mit der Ladegegenkopplung durch die geregelte Bewegung der Haltevorrichtung.

According to a second aspect of the invention, the object is achieved by a method for producing an electrically conductive connection of a storage module for electrical energy in a motor vehicle with an energy supply unit for providing electrical energy by means of a charging coupler system according to the first aspect. The process has the following steps:

• Active transmission of data by the transmission device of the charging coupler system,
• Receiving the transmitted data by the receiving device of the charging coupler system,
• Calculating the position of the charging negative coupling based on the position of the transmitting device and the relative position of the charging negative coupling to the position of the transmitting device by the computer unit,
• Regulating the movement of the holding device based on the calculation of the position of the charging counter coupling by the computer unit for establishing an electrically conductive connection of the charging coupling with the charging counter coupling,
• - Establish the electrically conductive connection of the charging coupling with the charging counter coupling by the regulated movement of the holding device.

The method according to the invention has the same advantages as have already been described above with regard to the charging coupler system according to the first aspect. A method designed in this way is therefore particularly advantageous since the data are actively sent out by a transmitting device. Receiving the data by the receiving device is therefore less sensitive to interference. The computer unit can determine the position of the charging negative coupling by means of the received data and the relative position of the charging negative coupling to the position of the transmitting device. In the following, the movement of the holding device can be regulated in such a way that the charging coupling is coupled to the charging negative coupling. The method according to the invention thus results in a connection of a consumer, in particular an electrically operated motor vehicle, with an energy supply unit that is not prone to errors, reliable and inexpensive, in a simple manner.

According to a preferred further development of the invention, it can be provided in a method that the transmitting device has a light-emitting diode that transmits data in the form of light signals and that an optical sensor of the receiving device receives the transmitted light signals. As described above, a light-emitting diode is a particularly advantageous transmission device since it has low costs and a long service life. Furthermore, a light-emitting diode can be specifically selected for its emitted lightwave spectrum and emit different lightwave spectra for different applications as required. A light-emitting diode also has the advantage of a high transmission power or a high intensity and range of the transmitted data. Cameras, diodes or other optical sensors can be used as optical sensors of the receiving device. A charging coupler system designed in this way enables an advantageously reliable data reception for determining the position of a charging negative coupling, in particular on a motor vehicle, with a light diode as the transmitting device. In this way, an error-free coupling of the charging coupling to the charging negative coupling can be reliably established.

According to a further preferred development of the invention, it can be provided in a method that the transmitting device transmits a predefined data sequence, in particular a unambiguous data sequence, preferably a repeated data sequence. As described above, a predefined data sequence, in particular an unambiguous data sequence, is particularly advantageous for error-free pairing between a consumer, in particular an electrically operated motor vehicle, and an energy supply unit. A clear data sequence reduces the influence of interferences like the transmitted data sequences from other consumers. It can thus be prevented that an energy supply unit tries to connect to different consumers at the same time or in an alternating manner.

According to a third aspect of the invention, the object is achieved by a motor vehicle with a charging negative coupling of a charging coupler system according to the first aspect. The motor vehicle also has the advantages mentioned, as already described above with regard to the charging coupler system according to the invention and / or the method according to the invention.
