Description

Charging station for an electric vehicle and charging infrastructure Technical area

The present invention relates generally to a charging station for an electric vehicle with the possibility of exchanging data packets with, for example, an external device and an external server according to previously defined rules. In particular, the present invention relates to a charging station for an electric vehicle, by means of which additional services are provided in addition to the typical services of a charging station, such as the provision of a charging connection for supplying energy to an electric vehicle and associated billing. background

In addition to their main task of supplying an electric vehicle with energy, modern charging stations for an electric vehicle often include other functions, such as the transmission of data to a mobile device. For example, data relating to the charging process of the electric vehicle connected to the charging station are transmitted from the charging station to the mobile terminal.

For example, DE 12 2012 011 773 A1 discloses a charging station with a near-field communication interface, by means of which the charging station communicates with a mobile terminal. The mobile terminal in turn communicates with a central server of the charging station operator. In this way, for example, consumption data or billing data can be exchanged between the charging station and the central server via the mobile device. The disadvantage of this solution is that the data transmission between the charging station and the central server is only possible when the mobile terminal has a good cellular connection.

Public charging stations are often used to charge electric car sharing vehicles that can be borrowed by different users of the car sharing service provider. To borrow, the user usually uses an application from the car sharing service provider on his smartphone, by means of which he selects the desired electric vehicle and sends a request to the car sharing service provider to borrow the Electric vehicle can send. If he receives positive feedback from a server of the car sharing service provider, the electric vehicle can be borrowed and consequently used. The prerequisite for this activation process, however, is that the user's smartphone can establish wide-area network communication with the server of the car sharing service provider.

If the user has a poor cellular connection, for example due to poor cellular network coverage or because the vehicle or smartphone is in a dead zone or an underground car park, no request to rent the electric vehicle can be sent to the car sharing service provider. Consequently, in this situation, the user cannot activate the electric vehicle for lending, which is disadvantageous for both himself and the car sharing service provider.

Brief outline

The present invention is therefore based on the object of providing a charging station for an electric vehicle and a charging infrastructure by means of which the aforementioned problems of the prior art are eliminated.

According to a first aspect, a charging station for an electric vehicle is provided, which has a charging connection for supplying an electric vehicle with energy, a near-field communication interface for near-field communication, which is designed to receive and send a data packet over a near-field, and a wide area network -Communication interface for wide area network communication, which is designed to receive and send a data packet over a wide area network. The near-field communication interface is also designed to provide the wide area network communication interface with a data packet for forwarding via the wide area network. Forwarding takes place via the wide area network in accordance with rules for forwarding previously defined in a set of rules for the charging station.

In other words, the charging station can provide a connection via the wide area network (WAN), for example an Internet connection, to an external device that communicates with the charging station via a near field. The charging station according to the invention therefore enables an external device to Exchange data packets over the wide area network, even if the external device itself is temporarily or permanently no connection to the wide area network available. Thus, for example, with an application of the external device, an electric vehicle connected to the charging station can be borrowed or a charging process can be started from this.

The connection of the external device to the wide area network by means of the charging station can be restricted by the rules for forwarding, according to which only data packets with previously defined data content are to be forwarded. The connection provided by the charging station via the wide area network is therefore restricted.

The near-field communication interface can be designed to establish wireless communication with the external device, for example by pairing. The external device is, for example, a mobile terminal such as a smartphone, a tablet, a smart watch, smart glasses or a notebook.

If the charging station and the external device are in communication with each other, a data packet sent via the near field communication from the external device to the charging station can be forwarded, for example, to an external (central) server to which the charging station can establish a connection via the wide area network. An external server is, for example, a server by means of which services, apart from a charging process and the associated billing for the energy supply of an electric vehicle, are processed.

Whether or not the data packet is forwarded depends on the forwarding rules that have been defined beforehand and that the set of rules can access. The rules for forwarding are therefore used to filter received data packets and only forward those that are to be forwarded for forwarding in accordance with the predetermined rules. In this way, the data traffic via the charging station can be restricted to certain applications or data content. This reduces the costs for the operator of the charging station, since the charging station does not grant internet access for every received data packet and thus the transferred data volumes are kept low. It can therefore be prevented that the wide area network of the charging station is loaded with other requests, for example through downloads or streaming services. Forwarding rules can be stored on a data memory of the charging station.

The near field communication can take place, for example, via Bluetooth®, WLAN, WiFi, NFC or the like. The wide area network may be a service offered by an Internet service provider Internet connection, for example, be a glass fiber ^¬ and / or Ethernet connection, or it may be an offered by a mobile operator mobile network, such as 3G, 4G, LTE and / or 5G, or a combination thereof. When using the 5G cellular network, the near-field communication interface and the wide area network communication interface can be implemented in a single component that supports peer-to-peer communication and a cellular network connection.

According to an advantageous embodiment, the wide area network communication interface is also designed to provide the near-field communication interface with a data packet for forwarding over the near-field. The forwarding via the near field is preferably carried out in accordance with rules for forwarding previously defined in the rules of the charging station. In this way, two-way communication between the external device and the external server can take place via the charging station. For example, a data packet with a request for charging and / or renting an electric vehicle connected to the charging station can first be forwarded from the external device to the external server by means of the charging station. A data packet with release information for charging and / or renting the electric vehicle can then be forwarded from the external server to the external device by means of the charging station.

The rules for forwarding are preferably based on the data content of the data packet for which forwarding is to take place. In order to achieve this, the charging station preferably comprises a logic which is designed to read and / and check the content of received data packets. In order to achieve a reduced amount of data, data packets that are transmitted by smartphones, for example, are usually compressed. A common compression method is, for example, "GNU Zip", or "gzip" for short. The logic can therefore be designed to unpack, open and / and read compressed data packets. In this way, the charging station can, for example, read the sender and / or the recipient of the data packet, in particular its IP address (es). You can also use the logic to do this be designed to decrypt encrypted messages in order to read and / or check them.

The data contents of the data packet, on the basis of which it is decided, preferably by the set of rules, whether the data packet is to be forwarded, can include an association with a specific, previously defined application. The previously defined application can include one or more of the following: a car sharing service, a payment or authorization process with regard to a charging process at the charging station, a service with regard to public transport companies, such as a ticket purchase or timetable information, a

Tourism services and tourism information. The charging station thus makes it possible to provide an application-specific connection via the wide area network, for example an Internet connection. For example, the charging station can be designed to display permissible applications, e.g. at the charging station or the external device, when starting or ending a charging process according to the rules for forwarding. Furthermore, the charging station can be designed to book and / or pay for a service via the wide area network communication provided by the charging station. For example, the user can use the charging station to purchase a ticket for public transport companies in the vicinity of the charging station.

The data in the data packet, on the basis of which it is decided, preferably by the set of rules, whether the data packet is to be forwarded, can include a specific, previously defined IP address of a recipient and / or a sender of the data packet. A previously defined IP address can comprise one or more of receiving the data packet from a specific terminal IP, central unit IP and / or server IP and a requested forwarding of the data packet to a specific terminal IP, central unit IP or / and server IP. For example, the rules for

Forwarding that a server IP of an external service provider in the data packet allows the data packet to be forwarded.

The data in the data packet, on the basis of which it is decided, preferably by the set of rules, whether the data packet is to be forwarded, can also include a specific, previously defined, unique identifier. A unique identifier can be, for example, a Unique Identification Number (UIN). An exemplary embodiment for effective use of the charging station is to be explained below. In this case, if the charging station has determined on the basis of the forwarding rules that the data packet is to be forwarded, and this forwarded data packet is a request and / or a confirmation for

Borrowing an electric vehicle connected to the charging station to an external server, e.g. a car sharing service provider, includes the charging station automatically terminating a charging process for the electric vehicle by forwarding this data packet. This makes renting the electric vehicle easier as there is no further step to exit the

Charging is necessary. For example, the charging station can automatically not only end the charging process by forwarding the data package that includes the request and / or the confirmation to rent the electric vehicle, but also transfer charging data, billing data or the like to the external server of the car sharing service provider.

In general, it can be advantageous for a car sharing service provider to receive billing information about the electric vehicle connected to the charging station. This billing information can be data about the charging process itself, such as a charged amount of energy or a charging time, but can also be data that have previously been transmitted from the external device to the charging station. For example, billing data of the borrowing user can also be automatically transmitted via the charging station to the external server of the car sharing service provider. In this way, payment for the lending process of the electric vehicle is ensured, regardless of whether the external device of the lending user only has access to the wide area network at the time of lending the electric vehicle or generally no. Advantageously, if the charging station has determined based on the rules for forwarding that the data packet is to be forwarded, and this forwarded data packet can be a request and / or a confirmation to lend an electric vehicle connected to the charging station to an external server, eg of a car sharing service provider, the charging station automatically transmits billing information to the external server with the forwarding of this data packet using the wide area network communication of the charging station.

In addition to the charging connection, a charging station can comprise one or more further devices for handling the charging process, for example for one Payment process or customer authentication. Most of the time, the charging stations also have sufficient installation space to accommodate additional devices, as these, as pillars, are anyway at a height that is adapted to human size. Preferably, the charging station further comprises a payment device that is designed to transfer amounts of money and / or an authentication device that is designed to carry out authentication and / or a display and / or touchpad device that is designed to display a screen display and / or to provide input, and / or a charging device for a mobile terminal, which is set up to charge a mobile terminal. One or more of the above devices for use by an external provider are preferably provided after a data packet has been received from the near-field communication interface and forwarded for forwarding to the wide-area network communication interface in accordance with the previously defined rules or has been received by the wide-area network communication interface and according to the previously defined rules for forwarding to the near-field communication interface was forwarded.

For example, the payment device and / or the authentication device and / or the display and / or touchpad device and / or the charging device for a mobile terminal can be activated by a corresponding communication interface via the near field and the near field communication interface and / or by a network via the wide area network and the wide area network communication interface received information in the data packet. This activation is preferably carried out automatically, for example by means of a data content of the data packet, such as a corresponding activation instruction.

A payment device is, for example, a card terminal for reading EC cards, money chips, credit cards or the like. In one exemplary embodiment, an external service can be provided with the aid of the charging station and the forwarding of a corresponding data packet from the near-field communication to the wide-area network communication, or vice versa. The data packet can contain payment information that is read by the logic of the charging station and automatically leads to the payment device being activated and the amount of money to be paid being displayed. The user can thus pay for the provider's external service, for example the car sharing service provider, directly, for example with his EC card. This makes the payment process easier for the user. In general, security can be increased if two-way authorization is carried out by using an external device for renting the electric vehicle, for example by means of an application on a smartphone, and paying with a physical card.

An authentication device is, for example, a barcode scanner or a fingerprint scanner or a similar device that can preferably read 2D or 3D codes. For example, the user can use a barcode-provided card from a service provider, for example a car sharing service provider, in order to authenticate himself.

A display and / or touchpad device is, for example, a screen with a touchpad function or a screen with selection fields or buttons arranged thereon. It can be used in a suitable manner for tourist purposes, e.g. for ticket sales or ticket information. For example, after a data packet has been successfully forwarded to an external server of a service provider, information from the service provider can be automatically displayed on the display and / or touch pad device of the charging station. Thus, the user can use a larger screen and select an offer from a service provider more easily.

If several services are requested at the same time or within a very short time, it may be necessary to determine a priority for processing the data packets by the charging station. The rules for forwarding can therefore include an acceptance filter in order to filter the received data packets according to their relevance. A request to rent an electric vehicle can have priority over a payment process.

Advantageously, the rules for forwarding also include deleting and / or discarding a received data packet that is not to be forwarded in accordance with the previously defined rules for forwarding.

For flexible adaptation of the charging station to a new service or a new device or a new requirement, the rules for forwarding a data packet via secure access via the near field and the near field communication interface and / or via the wide area network and the wide area network communication interface are preferred changeable. One The rules for forwarding can be changed, for example, by an authorized person.

In a preferred exemplary embodiment, the charging station further comprises an actuation device for establishing near-field communication with an external device. In this way, the external device can optionally be connected to the charging station, if so desired. The actuation device can be a touch display and / or an actuation element of the charging station. In a further embodiment, a confirmation device can be a reader for a card, in particular an RFID card. In such an embodiment, it is possible to establish near-field communication with an external device when the reader for an RFID card detects information on a card, in particular an RFID card. Nowadays, EC or credit cards are known with which contactless payment is possible. For such a contactless payment, some EC or credit cards transmit information using RFID communication. This information can be captured by the reader for an RFID card. In most cases of application, this information cannot be processed further, since this recorded information is usually not sufficient for an authentication of a user / customer. Therefore, in one embodiment, it is possible that near-field communication is established with an external device when the reader for an RFID card detects information that is insufficient, in particular, to be used to authenticate a user, in particular to enable a charging process . Accordingly, for example, a

Near field communication with an external device can be established when authentication using an RFID card fails. Authentication by means of an RFID card can also fail, for example, if an employee ID is used as the RFID card. This embodiment has the advantage that a charging station can be constructed relatively simply, since most of the charging stations include a reader for an RFID card for authentication. Likewise, a customer or a user usually has an EC or credit card with which contactless payment is possible, or another RFID-capable card. Thus, a customer or a user can establish near-field communication with an external device.

A simpler way of connecting the external device to the charging station via near-field communication is preferably that the charging station is also designed to establish near-field communication with an external device when an interaction with an electric vehicle takes place there. Manual actuation, for example of the actuation device on the charging station, is therefore not necessary to establish the connection.

The interaction with an electric vehicle is, for example, connecting a charging cable of the charging station to an electric vehicle or establishing communication between the charging station and an electric vehicle or other recognition of an electric vehicle at or near the charging station.

The charging station is preferably a capacitive and / or inductive charging station.

In a further aspect, the invention relates to a charging infrastructure which comprises the charging station described above and a central unit which is designed to communicate with the wide area network communication interface via the wide area network. The central unit can be used, for example, to transmit rules for forwarding to the charging station.

Brief description of the drawings

Further advantages, details and features of the device and the charging structure, as described herein, emerge from the following description of exemplary embodiments and from the figures.

1 shows schematically the communication between a mobile terminal, a charging station and a server for renting an electric vehicle according to the prior art;

2 shows a schematic view of an exemplary embodiment of a charging station according to the invention and a charging infrastructure according to the invention; and

3 shows a sequence of an exemplary use of the charging station according to the invention.

Detailed description of the drawings 1 shows a situation in which a person wishes to borrow an electric vehicle 12 connected to a charging station 10. The loan can be realized with the help of a mobile terminal 14 and an application of the car sharing service provider located on it. For this purpose, a data packet with a request to rent the electric vehicle 12 is usually sent via a wide area network communication 16 to a server 18 of a car sharing service provider, which can respond with a data packet with release information for the electric vehicle 12. Receipt of the release information by the mobile terminal device 14 can then activate a communication 20 between the mobile terminal device 14 and the electric vehicle 12 for renting the electric vehicle. Furthermore, the user can end the charging process of the electric vehicle 12 manually at the charging station 10. For example, as described in DE 12 2012 011 773 A1, the charging station 10 can send consumption data to the mobile terminal 14 via near-field communication 22, which the mobile terminal 14 can in turn send to the server 18 using the wide-area network communication 16.

The problem with the solution according to the prior art is that renting the electric vehicle 12 requires wide area network communication 16 between the mobile terminal 14 and the server 18. If the application of the car sharing service provider cannot be used due to a poor cellular connection of the mobile terminal 14, no release information for renting the electric vehicle 12 can be sent to or received from the server 18 and the electric vehicle 12 cannot be rented. The charging station according to the invention overcomes this disadvantage.

A charging station 110 according to the invention for an electric vehicle 112 can be seen in FIG. 2. The charging station 110 has a charging connection 114 for supplying the electric vehicle 112 with energy. Furthermore, the charging station 110 has a near-field communication interface 116 for near-field communication 118 in order, for example, to exchange a data packet with an external device 120 via a near-field. In Fig. 2, the external device is shown as a mobile terminal 120, such as a smartphone. Furthermore, the charging station 110 has a wide area network communication interface 122 for wide area network communication 124 in order, for example, to exchange a data packet with an external server 126 via a wide area network.

Thus, one from the external device 120 can use the near field communication 118 sent data packet are received by the near-field communication interface 116 and provided to the wide area network communication interface 122 for forwarding via the wide area network. The forwarding over the wide area network takes place according to forwarding rules previously defined in a set of rules 128 of the charging station 110. So only data packets are forwarded whose forwarding is permitted by the forwarding rules. The charging station 110 can thus provide the external device 120 with restricted access to the wide area network.

The rules for forwarding can, for example, be based on previously defined data contents of the data packet and, on the basis of the presence or absence of this data contents, the set of rules 128 can decide whether the data packet is to be forwarded. The data content provided for this can include, for example, an association with a specific, previously defined application. For example, the application can be assigned to a car sharing service. The user of the external device 120 can thus use the near-field communication 118 of the charging station 110 to send a request to rent the electric vehicle 112 connected to the charging station 110 to the external server 126 of the car sharing service provider. The external server 126 can in turn send a data packet with release information to the charging station 110.

In addition to release information for renting the electric vehicle 112, the data packet sent by the external server 126 can also contain information for the charging station 110, which instructs it to end the charging process for the electric vehicle 112. If the wide area network communication interface 122 is also designed to provide the near-field communication interface 116 with a data packet for forwarding via the near-field, the data packet with the release information can be sent via the

Near field communication 118 can be sent from charging station 110 to external device 120. It goes without saying that the data packet is only forwarded if the previously defined rules for forwarding permit such forwarding. After receiving the release information, the external device 120 can enter into communication 130 with the electric vehicle 112 and unlock it. In this way, a person can borrow an electric vehicle 112, even if they use an external device 120 for this purpose, which is temporarily or permanently disconnected from the wide area network. In addition to the charging connection 114, the charging station 110 can comprise further functionalities and devices. These may be, for example, a payment device 132 or / and an authentication device 134 and / or a display ^¬ / or Touchpadvorrichtung 136 or / and a charging device 138 for a mobile terminal 120th Advantageously, a data packet forwarded by the charging station 110 in accordance with the previously defined rules for forwarding can include an instruction to one or more of the named devices or other devices of the charging station 110. Such an instruction can be an activation of the corresponding device (s) so that they can be used by a user. For example, the user can use the display device 136 of the charging station for further inputs instead of his mobile terminal device 120.

It goes without saying that the near field communication 118 for a communication between the external device 120 and the charging station 110 must first be set up, for example by pairing. This can take place automatically when the external device 120 is in the vicinity of the charging station 110, or it can be initiated in a targeted manner. For this purpose, the charging station 110 can have an actuation direction 140, such as a button 140, the actuation of which enables the near-field communication 118 to be established between the charging station 110 and the external device 120 located in the vicinity of the near-field. In the event that the charging station 110 comprises the display and / or touchpad device 136, this can also represent the actuating device 140. The charging station 110 can be assigned to a central unit 142, which together represent a charging infrastructure. The central unit 142 can communicate with the charging station 110 via the wide area network 124 by means of the wide area network communication interface 122. For example, an authorized person can access the charging station 110 by means of the central unit 142 in such a way that the rules for forwarding can be changed, for example deleted or others can be added. A sequence of an exemplary use of the charging station 110 according to the invention is shown in FIG. 3. In step S1, the near-field communication 118 can be established between the charging station 110 and the external device 120. The construction can take place, for example, in that a user actuates the actuation device 140, for example an actuation element in the form of a button 140, or there is an interaction between the charging station 110 and the electric vehicle 112.

Subsequently, in step S2, a data packet sent from the external device 120 to the charging station 110 can be received through the near-field communication interface 116 of the charging station 110. The data packet received from the near-field communication interface 116 can be read in step S3 by a logic of the charging station 110 and checked for its content. If necessary, the received data packet can be compressed and first unpacked using the logic.

Based on the data content of the received data packet, a decision can then be made in step S4, using previously defined rules for forwarding in the set of rules 118, whether the rules for forwarding allow the data packet to be made available to the wide area network communication interface 122 for forwarding via the wide area network 124. Is according to the rules for

Forwarding of not forwarding the data packet, this can be deleted and / or discarded in step S4 '. If the data packet is to be forwarded according to the rules for forwarding, in step S5 the data packet is forwarded to the external server 126 via the wide area network communication interface 122 via the wide area network 124.

At the same time, if the data packet is forwarded in the affirmative by the set of rules 128 of the charging station 110 in step S4, a further process at the charging station 110 can be triggered. For example, the data packet could contain information for or instruction to the charging station 110, which instructs the charging station 110 to end a charging process of the electric vehicle 112 connected to it. If the logic of the charging station 110 detects such an instruction in step S4a, it can, for example, automatically end the charging process of the electric vehicle 112 in step S4b, that is to say without further instruction from the user.

For example, the data packet sent to the charging station 110 contains a request to rent the electric vehicle 112 connected to it it makes it easier for the user to rent the electric vehicle 112 by eliminating additional steps for ending the charging process.

Alternatively, the data packet could contain any other instruction for the charging station 110 which instructs the charging station to carry out an action in step S4a. For example, information could be included that instructs the payment device 132 to display an amount contained in the information in the data packet so that the user of the external device 120 can use the payment device 132 to pay for an external service. which differs from charging an electric vehicle 12 by the charging station 110. The instruction to the charging station 110 contained in the information can be executed in step S4b.

If the external server 126 sends a data packet to the external device 120, this can be received through the wide area network communication interface 122 of the charging station 110 in step S6. The data packet received from the wide area network communication interface 122 can be read in step S7 by the logic of the charging station 110 and checked for its content. If necessary, the received data packet can be compressed and first unpacked by means of the logic.

Based on the content of the data packet, it can then be decided in step S8, using the previously established rules for forwarding in the set of rules 118 whether the rules for forwarding allow the data packet to be made available to the local radio communication interface 122 for forwarding via the near field 118. If the data packet cannot be forwarded according to the forwarding rules, it can be deleted and / or discarded in step S8 '. If the data packet is to be forwarded according to the rules for forwarding, in step S9 the data packet is forwarded to the external device 120 via the wide area network communication interface 122 via the near field 118.

At the same time, if the data packet is forwarded in the affirmative by the rules 128 of the charging station 110 in step S8, a further process at the charging station 110 can be triggered. For example, the data packet could contain an instruction to the charging station 110, which instructs the charging station 110 to end a charging process for the electric vehicle connected to it. If the logic of the charging station 110 detects such an instruction in step S8a, it can, for example, automatically end the charging process of the electric vehicle 112 in step S8b. Alternatively, the data packet could contain any other instruction for the charging station 110, which instructs the charging station in step S8a to carry out an action, as described in a manner analogous to step S4a. The instruction contained therein to the charging station 110 can be executed in step S8b.

In the examples presented, different features and functions of the present disclosure have been described separately from one another and in certain combinations. It goes without saying, however, that many of these features and functions can be freely combined with one another where this is not explicitly excluded.
