State of the art

Charging stations for charging electrically powered vehicles are generally known. In the DE 10 2009 016 869 A1 describes, for example, an automatic charger that has at least one connection socket for a charging cable or a permanently installed charging cable. The loading machine forms part of a petrol station and is designed for fast charging with high output, but can also manage low charging outputs for gentle charging.

The disadvantage is the long waiting times when charging electrically powered vehicles, which can be 30 minutes or more, depending on the vehicle type and equipment, even with quick charging processes. This is particularly disadvantageous on long-haul routes, since usually several recharging processes have to be carried out here. Many drivers of electrically powered vehicles perceive these waiting times as negative, since not every charging station is located in a location with a well-developed infrastructure that the driver can use to bridge the waiting time.

In the DE 10 2009 016 869 A1 This problem is solved in that the petrol station has, in addition to the automatic loading machine, a further traffic infrastructure for an electrically powered vehicle, namely a changing place. At this exchange station, the battery of the electrically powered vehicle can be replaced using a robot. This means that the driver of an electrically powered vehicle does not have to wait for the battery to charge, but can continue driving immediately after replacing the battery.

The disadvantage is that such a battery replacement can only be implemented with a high logistical effort, since a charged battery of the correct type must always be available for a vehicle at an exchange location. In addition, due to its complex structure, such a changing place is expensive to buy and maintain. Precisely because of the generally limited range of electrically powered vehicles, the densest possible network of traffic infrastructures for electrically powered vehicles is desirable. Such a dense traffic infrastructure network is due to the high cost of the DE 10 2009 016 869 A1 known exchange places, however, not feasible.

task

It is therefore the object of the present invention to provide an inexpensive traffic infrastructure for electrically powered vehicles which supplies the vehicle with a charged energy store with minimal logistical outlay, without the driver feeling the waiting time caused thereby as negative.

Statement of the invention

This object is achieved in connection with the features of the preamble of claim 1 in that the charging station has a communication unit which, when charging the vehicle, communicates via a data connection with an electronic device carried by the vehicle while it is traveling.

Preferred embodiments are the subject of the dependent claims.

The invention is based on the knowledge that it is not absolutely necessary to shorten the waiting times when charging electrically powered vehicles. Rather, it is sufficient if the drivers of these vehicles no longer perceive this waiting time as negative. This is realized by the communication unit according to the invention, which enables the driver, for example, to receive films on the electronic device carried by his vehicle while the vehicle is being charged. The communication between the communication unit and the carried electronic device is preferably bidirectional, ie the communication unit can receive data from the carried electronic device via the data connection and also data via the Send data connection to this. The data can be sent and received at the same time or at different times. The measures required for this are sufficiently known to the person skilled in the art.

Thanks to the bidirectional communication, the driver can e.g. Check the content sent to the electronic device being carried by charging the vehicle while it is charging. The electronic device carried can then transmit this data to the communication unit via the data connection, so that the charging station can adapt the content sent to the electronic device carried in accordance with the input.

As a result, the energy storage device of the electrically driven vehicle, which e.g. a rechargeable energy storage on an electrochemical basis, i.e. an accumulator - can be charged without the driver feeling the waiting time caused thereby as negative. In contrast to the exchange station known from the prior art, the charging station according to the invention is particularly cost-effective in terms of its acquisition and maintenance costs. In addition, the logistical effort required in the known exchange place for the battery replacement in the charging station according to the invention is completely eliminated.

The charging station according to the invention can e.g. by connecting it to an AC network. Additionally or alternatively, it is of course also possible for the charging station to have its own energy store and / or to be connected to one.

An electrically powered vehicle in the sense of the present invention can e.g. an exclusively electrically powered vehicle, i.e. an electric vehicle. The electrically powered vehicle can also be a hybrid electric vehicle, in which, in addition to an electric motor, another energy converter, such as an internal combustion engine for which propulsion is used. In particular, electric bicycles with pedal drive also represent hybrid electric vehicles in the sense of the present invention, since they have both an electric motor and another energy converter, namely the pedal drive, which converts the driver's muscle energy into drive energy. The electrically powered vehicle can generally be a land, water and / or aircraft. Additionally or alternatively, it can e.g. be a transport vehicle set up to transport parcels and / or other goods. In particular, the electrically powered vehicle can be a rail and / or road vehicle. Road vehicles are e.g. Cars, trucks, buses, motorcycles and bicycles. An aircraft is e.g. a flight drone, such as a transport flight drone set up to transport packages and / or other goods. The charging station according to the invention can e.g. also have a storage area for the storage of packages and / or other goods and in this way act as a logistics center for the transport vehicles set up for the transport of packages and / or other goods. The loading and / or unloading of a transport vehicle, e.g. while it is being charged with electrical energy via the charging connection, automatically. For this purpose, the charging station can, for example, have a robot that e.g. is controlled accordingly by a computing unit of the charging station. The charging station according to the invention can e.g. at a petrol station, in a parking garage, in another public place and / or in private areas, e.g. in a private garage. Preferably, the charging station according to the invention is a stationary charging station, i.e. permanently installed in one place.

The electronic device carried by the vehicle during its journey, with which the communication unit communicates via the data connection when charging the vehicle, can e.g. be an on-board system of the electrically powered vehicle and / or a mobile electronic device. The mobile electronic device can e.g. a smartphone, tablet, laptop, MP3 player or navigation device. Here it is e.g. irrelevant whether the mobile electronic device is to be assigned to the driver or another occupant of the electrically driven vehicle, since in both cases the mobile electronic device is carried by the electrically driven vehicle while it is traveling.

The on-board system can e.g. a central on-board computer, an entertainment system set up for playing film and / or audio files, a loudspeaker, a display, a navigation system, a communication system or another data storage device of the electrically driven vehicle. In addition to a data memory connected to the on-board system, such a data memory can e.g. can also be an RFID (radio frequency identification) transponder attached to the vehicle.

Of course, a mobile electronic device can also be connected to the vehicle, for example via a data cable, and in this way act as an on-board system of the electrically driven vehicle. The on-board system can also be permanently integrated into the vehicle, for example. Such a permanently integrated on-board system is connected to the vehicle structure in such a way that it is only in the As part of repair, conversion, dismantling and / or maintenance work, but not within the normal operational sequence of the vehicle can be removed from it.

The charging station according to the invention can also, as provided in a preferred embodiment, be connected to a computer network. This computer network is preferably a public network, e.g. the Internet. Additionally or alternatively, the computer network can also be a non-public network, e.g. an internal intranet.

The connection of the charging station to a public network, such as the Internet, is advantageous because in this way the driver can use the Internet while charging his vehicle by using the electronic device carried, via the device and the communication unit of the charging station existing data connection accesses the Internet. Particularly in regions with a poorly developed mobile radio infrastructure, it is particularly advantageous for the driver if he can use a fast internet connection provided by the charging station.

Even in a traffic jam situation in which the internet capacity made available via the external mobile radio infrastructure is rapidly decreasing due to the large number of terminal devices located in a mobile radio cell, it is advantageous if the driver is provided with fast internet access by the charging station according to the invention, so that the driver during his vehicle charging, all the advantages of the Internet, such as can access web pages, email communication and download or upload files.

The connection of the charging station to a non-public network, such as an internal company intranet, is also advantageous. For example, identification information entered by the driver at the charging station, e.g. can consist of a user ID and a PIN (personal identification number), can be transferred via the intranet directly into the billing system of the operating company of the charging station. After the identification information has been checked by a computing unit on the intranet, it can then e.g. start the charging process of the electrically powered vehicle by transmitting a corresponding release information via the intranet to a computing unit of the charging station.

In general, in the present invention, such identification information can of course also be entered by the driver into the electronic device carried along, which then transmits this information to the communication unit of the charging station via the data connection.

The charging station according to the invention can have a data memory for storing data which is sent from and / or received by the communication unit when charging the vehicle via the data connection to the electronic device carried along. This is e.g. advantageous if the charging station cannot be connected to a computer network because the infrastructure required for this is not available at the location of the charging station. In this case, data such as Movies, audiobooks, commercial clips or regional information about the surroundings are stored in the charging station's data storage. This makes it possible for the driver - although the charging station is not connected to a computer network - to be supplied with this data by retrieving it from the data storage device when charging the vehicle and sending it from the communication unit to the electronic device carried along via the data connection ,

However, the charging station according to the invention can of course also have the data memory described above if it is connected to a computer network. It is advantageous here that e.g. the data stored in the data memory via remote maintenance via the computer network, e.g. the Internet and / or an internal company intranet, can be read out and / or changed. However, the charging station according to the invention can e.g. also have a satellite communication device so that it can communicate the data that is sent by the communication unit when charging the vehicle via the data connection to and / or received by the electronic device carried over a satellite connection. The charging station can e.g. have a data memory and / or a satellite communication device and / or be connected to a computer network. The charging station is preferably connected to the computer network via the satellite connection.

In the present invention, the charging connection and / or the data connection is preferably a cable connection, in particular a cable connection with at least one plug connector. For example, a socket can be provided both for the charging connection and for the data connection on the vehicle, in each of which a plug of a charging cable or data cable connected to the charging station can be inserted. In this case, the charging cable and the data cable can be combined to form a common cable by means of a common sheath, or each can be present as an individual cable. The charging connection and / or the data connection as a cable connection It is advantageous to design it, since this enables particularly high energy or data transmission rates to be achieved.

In a preferred embodiment of the present invention, it is provided that the charging connection and / or the data connection is a contactless connection. The charging connection can e.g. be set up for inductive energy transmission. The charging connection is preferably set up for inductive energy transmission in the near field. For example, the charging connection can have at least two coils that connect the charging unit of the charging station and the energy store of the vehicle to one another via an inductive coupling.

The contactless data connection can e.g. a cellular connection or a Wireless Local Area Network (WLAN) connection. The contactless data connection can e.g. a Bluetooth connection or a connection based on infrared and / or laser light. Combinations of the aforementioned compounds are also possible. Additionally or alternatively, the contactless data connection is preferably a short-range data connection that has a range of a maximum of 1000 meters, a maximum of 750 meters, a maximum of 500 meters, a maximum of 250 meters, a maximum of 150 meters, a maximum of 100 meters, a maximum of 50 meters, and a maximum of 25 meters from the charging station , maximum 20 meters, maximum 15 meters, maximum 12 meters, maximum 10 meters, maximum 8 meters, maximum 6 meters, maximum 5 meters, maximum 4 meters, maximum 4 meters, maximum 3 meters, maximum 2 meters, maximum 1 meter, maximum 0.5 meters, maximum 0.25 meters, maximum 0.1 meters, maximum 0.05 meters or maximum 0.01 meters.

In a further preferred embodiment of the present invention it is provided that the communication unit at least partially communicates with the electronic device carried along via the charging connection when the vehicle is being charged. In other words, in this embodiment the charging connection is also used at least partially as a data connection. The at least partial use of the charging connection as a data connection is advantageous since, in contrast to a separate use of the charging connection and data connection, an even higher data transmission rate can be achieved in this way. In this embodiment, the charging connection is preferably also the data connection. In other words, both the transmission of the electrical energy from the charging station to the energy storage device of the vehicle and also the complete communication between the communication unit and the electronic device carried along takes place via the charging connection. It is advantageous here that only a connection between the charging station and the vehicle has to be established, which then functions both as a charging connection and as a data connection.

The partial or full use of the charging connection as a data connection can e.g. can be realized in that the data signal to be transmitted is modulated on the charging station side to the charging current and demodulated again by the latter on the vehicle side. For example, the modulation to the charging current can take place directly within the communication unit and the demodulation within the carried electronic device. In this case, the communication unit and the electronic device carried along thus form a carrier frequency system. In addition to the communication unit or the electronic device carried, other components of the charging station or the vehicle can also function as components of such a carrier frequency system. Even when data is transferred from the electronic device carried to the communication unit, the charging connection can be used partially or completely as a data connection. In this case, the data signal is modulated on the vehicle side to the charging current and demodulated again by this on the charging station side.

The person skilled in the art is generally aware of the measures required for data transmission via existing power lines. He knows such techniques e.g. under the name PowerLAN, which is also known as dlan or Powerline Communication (PLC). In the present invention, the communication unit can of course also at least partially communicate with the carried electronic device via the charging connection when the vehicle is charging, if the charging connection is a contactless connection. It is also preferred here that the charging connection is the data connection at the same time.

In a further preferred embodiment of the present invention it is provided that the communication between the communication unit and the electronic device carried is unidirectional communication. In this embodiment, the communication unit can, for example, only be set up to transmit data via the data connection to the electronic device carried along. As a result, the communication unit cannot receive any data from the carried device. However, the configuration of the communication unit as a simple transmission unit is nevertheless advantageous since it is particularly inexpensive. In this embodiment, however, the communication unit can, for example, also only be set up to receive data from the electronic device carried along. For example the communication unit only receives identification information sent by the vehicle and / or the electronic device carried along. This is particularly advantageous if, for example, the vehicle cannot be located, or only to a limited extent, via the external mobile radio infrastructure. Even in such a scenario, the location of the vehicle can be precisely determined using the identification information received from the communication unit and, for example, transmitted to a logistics center via a computer network connected to the charging station. This embodiment is therefore advantageous, for example, in the field of truck logistics, since the positions of the individual vehicles in a truck fleet can be monitored from the logistics center without the need for an external mobile radio infrastructure or another location system. The rest times of the driver of the electrically powered vehicle can also be monitored in this way without having to resort to other location systems. This embodiment of the invention could also be used, for example, in the emergency services. Even in the event of a failure of the conventional location systems, the positions of individual electrically powered emergency vehicles, such as police, ambulance or fire service vehicles, can still be determined via the charging station according to the invention. In addition, the configuration of the communication unit as a simple receiving unit is also advantageous for cost reasons.

A further preferred embodiment of the present invention provides that the charging station has, in addition to the communication unit, a sensor which is set up to provide identification information of the vehicle and / or of the electronic device carried and / or of another electronic device carried by the vehicle while it is traveling capture. The sensor can e.g. be an optical sensor. This enables the driver to identify himself at the charging station, for example, by means of a code which is shown on the display of a mobile electronic device carried while driving. This can e.g. be the driver’s smartphone. After checking the code detected by the sensor, which can be a QR code, for example, by comparing it with a reference, e.g. can be stored in a data storage device of the charging station or in a computing unit of a computer network connected to the charging station, the charging station can then automatically start, for example, charging the vehicle via the charging connection and / or data communication between the communication unit and the on-board system of the vehicle. The mobile electronic device carried by the driver in addition to the on-board system is thus in this case another electronic device carried by the vehicle while driving.

The identification information is preferably also acquired automatically. For example, a camera could record the license plate of the vehicle as identification information. After checking the license plate, for example by means of suitable recognition software, which, by comparing it with suitable reference values, assigns the captured image of the license plate to a user, the establishment of the data connection and / or the transmission of the data can then also be started automatically by a computing unit of the charging station become. With the automatic Acquisition of the identification information is advantageous in that no manual input by the driver at the charging station is required. The driver only has to park his vehicle at the charging station, which automatically recognizes the vehicle or the driver via the identification information and automatically starts the establishment of the data connection and / or the transmission of the data.

It is particularly advantageous if, as is provided in a further embodiment of the method according to the invention, the establishment of the charging connection and / or the start of the charging of the vehicle also takes place automatically on the basis of the identification number detected. As a result, the driver no longer has to leave his vehicle at all, since all the steps required for charging the vehicle and providing the data connection are carried out automatically by the charging station. For example, a robot connected to a computing unit of the charging station could be provided, which automatically establishes the charging connection and the data connection after the identification of the vehicle or the driver by the computing unit by inserting a charging cable and a data cable into sockets provided for this purpose on the vehicle. The computer unit of the charging station can then automatically start charging the vehicle via the charging connection and transmitting data via the data connection.
