Description

The invention relates to an arrangement and a method for supplying mobile electrical consumers, in particular small electrical appliances or electric vehicles.

Mobile electrical consumers, especially small electrical appliances, such as cell phones or laptops, or electric vehicles, such as e-bikes or battery-powered low or zero emissions vehicles, are generally charged by the user in the home area. For the user of the mobile electrical consumer, there is sometimes the problem that the mobile electrical consumer must be charged outside the home area if necessary. In particular, in electric vehicles is additionally the requirement that charging devices that are spatially accessible to the electric vehicle, must be present.

Especially for charging larger electric vehicles charging stations are already known from the prior art, which provide depending on the design of an AC, three-phase or DC and thus are able to provide the electric vehicle with the required power for charging the batteries.

However, the disadvantage of such charging stations lies in particular in a high cost and deployment effort, which currently counteracts a widespread distribution of such charging stations.

The object of the present invention is to provide an arrangement for the supply of mobile electrical consumers, which requires a minimal provisioning and cost and which can be variably integrated into any consumer networks, (as well as a method that can be carried out with the arrangement).

The object is achieved by an arrangement with the features listed in claim 1 and by a method with the features listed in claim 6. Preferred developments emerge from the respective subclaims.

An arrangement for supplying mobile electrical consumers, hereinafter also referred to as consumers, according to claim 1, has a charging station with an NFC interface, a control unit and a connection element for the consumer and a communication unit, a user unit with an NFC interface and a central unit with a database on. In this context, supplying the consumer with electricity, in particular for charging the consumer's batteries, is specifically referred to as supplying the consumer.

The control unit according to the invention is the component by means of which all necessary switching and connection processes are controlled within the charging station. In this case, the control unit according to the invention is associated with a charging station identity code, which allows identification of the charging station and which is formed for example by a numeric code or an alphanumeric code.

In contrast, the connection element is the component of the charging station, to which the consumer is connected by means of a corresponding plug-in device, and which can be switched on and off by means of the control unit. In the present case, the connection element has one or more slots, which may have different structures and electrical connection data. In the simplest case, at least one slot is a conventional 230 V connection. Cumulatively or alternately another slot can be formed, for example, according to the EnergyBus standard and thus be designed directly on the energy consumption of batteries easier electric vehicles. In particular, in the implementation of the EnergyBus standard, the connection element is able to perform an intelligent detection of each connected consumer. In this context, for example, the battery characteristics of the consumer are determined in order to provide the required amount of energy for its charge on this basis.

In the presence of multiple slots, the connection element is preferably capable of individually adapting the use of slots and, for example, by means of a priority circuit or occupancy detection to release only one slot or divide the streams to be provided between the slots in a release of multiple slots.

In the present case, the user unit is understood to be the component of the arrangement via which a potential user of the charging station gains access to it. In this case, the user unit is able to provide a user identity code which enables identification of the potential user of the charging station and which can be transmitted by the user unit to the communication unit. According to the invention, the user unit is further able to connect to the charging station, the connection being made as an NFC connection between the NFC interface of the user unit and the NFC interface of the control unit. The special advantage of the NFC connection lies in In this context, the NFC connection can only be maintained over very short distances, and thus a possible, unauthorized interference with the connection by third parties is at least made more difficult.

Within the arrangement, the central unit represents the component which enables central storage and provision of data relevant to the provision of power to the consumer by the arrangement. In particular, a charging station data record is stored in the database of the central unit according to the invention, which contains, on the one hand, the charging station identity code and, on the other hand, a charging unit and a unit price, in each case based on the power to be provided. In this context, the billing unit and the unit price are specified in particular by an operator of the charging station and preferably already stored in the billing data record of the database prior to the access of the user of the charging station. In the simplest case, such a billing unit consists of a fixed amount of energy (for example, one kilowatt hour) or a fixed period of power delivery.

The communication unit according to the invention is able to provide a connection to the central unit, wherein the communication unit according to the invention can be assigned to both the user unit and the control unit of the charging station and wherein the provisionable connection with the central unit according to the invention as a remote data connection, for example as a GSM connection, is trained.

The assignment of the communication unit to the control unit of the charging station has the particular advantage that the control unit, via the communication unit, is directly configurable by means of the central unit by the corresponding charging station data set is transmitted from the central unit to the control unit. In this context, the arrangement according to the invention makes it possible for the charging station to be activated also with a user unit which itself has no communication unit. Such a user unit represents, for example, an RFID card by means of which a user activates the charging station and selects the corresponding billing unit at the charging station.

In addition, the assignment of the communication unit to the charging station makes it possible for the charging station to perform an automatic registration and an automatic transmission of the charging station identity code when it is put into operation.

According to the invention, the charging unit identity code and the user identity code are transmitted by the communication unit, by means of the remote data connection, to the central unit and authenticated in the central unit; this means checked for presence and correctness. In this case, for example, a check of the transmitted charging station identity code takes place with the charging station identity code stored in the charging station data record.

After successful authentication of the charging station and user identity code, an activation code can be generated by the central unit, which is transferable from the central unit to the communication unit and from this to the control unit.

The control unit is further able to verify the transmitted enable code and subsequently to connect the connection element. The verification of the activation code means in this context that the control unit is able to recognize the unlocked accounting unit by means of the activation code and to unlock the connection element for the time period or amount of energy stored in the accounting unit.

Parallel to the transmission of the activation code, a billing data record can be stored according to the invention in the central unit, which contains a number of unblocked billing units and the respective unit prices assigned to them. Furthermore, the billing dataset can be prepared in an evaluable manner in accordance with the invention and serves primarily for the billing of the delivered amount of energy or time units with respect to the charging station operator.

As a result of the arrangement, an easily implementable solution for supplying mobile electrical consumers is provided in a particularly advantageous manner, which can be implemented with low on-site installation effort and low provisioning costs and which can be connected to any supply networks. In this context, the arrangement allows, for example, the connection of the charging station to a home power network of the charging station operator, in which the deliverable amount of energy is provided for example by a photovoltaic system. Furthermore, a charging station of an arrangement according to the invention can be installed at arbitrary locations, for example on cycle paths or seating due to the low on-site installation effort. The only prerequisite in this connection must be a connection of the charging station to the charging network of the charging station operator. In this regard, it is also advantageously possible to assign the charging station, for example, a parking meter, so that in particular an owner of a Electric vehicle is allowed to charge this during a parking operation at the same time.

The charging station data set stored in the central unit has, in a preferred variant, several different accounting units together with assigned unit prices. In this way, as a particular advantage of the arrangement, it is possible to provide different power levels with different maximum values of the outputable current. In the present case, a billing unit with an associated unit price is deposited for each service level, the deposit in this case taking place both in the central unit and in the control unit.

In this way can be provided in a particularly advantageous manner, depending on the nature of the consumer to be supplied, a low power level, for example, for charging small electrical appliances, or a high power level, for example for charging electric vehicles, wherein the selection of the appropriate power level by the User of the charging station takes place.

In order to ensure that the connected consumer corresponds to the retrieved power level, a simple current measuring sensor is preferably arranged within the charging station, which detects the current tapped at the connecting element and, for example, outputs a warning signal or interrupts when a maximum value of the tapped current is exceeded.

As a further advantage of different billing units within the charging station data set, the billing units can be assigned different time limits. In this way, it is possible in particular for a billing unit based on the unlocked amount of energy that, depending on the selected billing unit, the amount of energy associated with this only for a limited period by the user of the charging station can be tapped.

Permanent occupancy of the charging station by a single user with a low power consuming consumer can thus be effectively prevented.

As a special technological advantage of the arrangement according to the invention allows the operator of the charging station by means of the central unit variably parameterize the control unit and in this way the corresponding charging station record with the billing unit and the unit price and as needed with different types of billing types, such as billing via SMS or credit card , can be transmitted to the control unit.

Furthermore, the arrangement according to the invention has the advantage that the operator of the charging station can release it for use only for a desired period of time by storing a corresponding activation period in the charging station data record. The charging station can then be used exclusively by a user in the given period, for example on weekdays from 8 am to 6 pm.

As a particular advantage, a technical solution for a parking space management can be provided beyond the supply of mobile consumers at the same time by assigning a parking space to the charging station. The billing of the parking space use can be done in this case particularly advantageous on the billing units of the charging station.

In a preferred development of the arrangement, the central unit is assigned a payment module, by means of which a payment process can be carried out. In the present case, the payment process designates the payment of the retrieved amount of energy by the user of the charging station and, according to the invention, is carried out on the basis of the billing data record stored in the central unit.

The payment module can be connected, for example, directly to a credit institution of the charging station operator, so that the payment process by direct debit or credit card method is feasible.

Alternatively, the payment module can also be provided by a mobile service provider or connected to a payment system known per se, for example PayPal.

Furthermore, a further advantageous variant of the arrangement provides that a functional check of the charging station can be carried out by means of the control unit. The function check is carried out according to the invention after the NFC connection by the user unit and serves primarily to inform the potential user of the charging station on their functional condition and to ensure the proper implementation of the desired power supply.

Depending on the function check, the charging station identity code can then be output, which is then transmitted to the communication unit and further processed according to the invention.

By such a function check can be ensured in a particularly advantageous manner that a potential user of the charging station in time and especially before Performing a selection and payment process is informed about a possible malfunction of the charging station.

In a particularly advantageous development of the invention, the communication unit is connected to the control unit of the charging station so that the remote data connection can be provided directly between the charging station and the central unit.

Since the remote data connection is formed in the training mentioned here directly between the charging station and the central unit, there is the particular technological advantage that no communication unit must be provided on the user unit and the user unit can therefore be provided particularly simple and therefore inexpensive.

In this case, the user unit can be designed, for example, as a chip card with an NFC interface which the potential user of the charging station has available and on which the user identification code is stored. The user identification code is transmitted to the control unit after making the NFC connection and via this to the communication unit.

The information of the potential user of the charging station on the respective accounting units and unit prices takes place here for example by means of a preselection of the appropriate charging socket by the user using an Internet database.

Alternatively, in this respect also a corresponding display can be installed at the charging station, which informs the potential user, preferably after establishing the NFC connection by means of the user unit, about the applicable billing units and the associated unit prices and then provides the potential user with a choice whether a Supply process to be performed according to the characteristics listed above or not.

Alternatively, the communication unit is connected in another advantageous embodiment of the invention with the user unit.

In this case, it is possible, on the one hand, to provide the remote data connection between the user unit and the central unit in order in particular to transmit the user identification code directly from the user unit to the central unit. On the other hand, in this case the charging station identity code is transmitted after the provision of the NFC connection between the user unit and the control unit to the user unit and from there via the communication unit to the central unit.

At the same time, the training provided here by means of the user unit enables interactive communication between the user of the charging station and the central unit, within which the user can interrogate the charging units and unit prices of the charging station and on the other hand can confirm the supply process and the associated payment.

The transmission of the activation code is in this case from the central unit to the user unit and from there by means of NFC connection to the control unit of the charging station.

As a particular advantage of this embodiment, the intrinsic functionality of NFC and data-capable user units, in particular smartphones, can be used, wherein the supply process according to the invention is controlled, for example, via a corresponding app.

Furthermore, it is possible to dispense with an additional communication unit connected to the control unit.

An inventive method for supplying mobile electrical consumer is preferably carried out by means of an arrangement with the features of claim 1, reference being made to the above description of the arrangement and the arrangement summarizes a charging station, comprising an NFC interface and comprising a control unit, which a charging station identity code is assigned and having a connection element for a mobile electrical consumer, wherein the connection element by means of the control unit is switched on and off, a central unit, comprising a database in which a charging station data set consisting of the charging station identity code, a billing unit and a unit price deposited is a communication unit, with which a remote data connection to the central unit can be provided and a user unit, comprising an NFC interface, wherein by the user unit ei n user identity code is providable.

• g) Übertragen des Freischaltcodes von der Kommunikationseinheit an die Steuerungseinheit,
• h) Verifizieren des Freischaltcodes und Zuschalten des Anschlusselements mittels der Steuerungseinheit.

The method according to the invention comprises the following method steps:

• a) providing an NFC connection between the user unit and the control unit and transmitting the charging station identity code from the control unit to the communication unit,
• b) transmitting the user identity code from the user unit to the communication unit,
• c) providing a remote data connection between the communication unit and the central unit and transmitting the charging station identity code and the user identity code to the central unit,
• d) authenticating the transmitted charging station identity code and the user identity code and generating a release code in the central processing unit,

• g) transmitting the activation code from the communication unit to the control unit,
• h) verifying the activation code and connecting the connection element by means of the control unit.

In the first method step a), an NFC connection is made available between the user unit and the control unit via the NFC interfaces. To set up the connection, for example, the user unit in the region of the NFC interface of the control unit is stopped or inserted into a correspondingly provided receiving device. Upon successful provision of the NFC connection, the charging station identity code is transmitted to the communication unit. According to the invention, the charging station identity code allows an identification of the charging station to be used in each case within the method and is formed, for example, by a numerical code or an alphanumeric code.

After the transfer of the charging station identity code is carried out in the second method step b) additionally a transmission of the user identity code from the user unit to the communication unit, so that there are for the further procedure in the communication unit, both the charging station identity code and the user identity code.

The user identity code in this context allows identification of the user of the charging station and is for example also formed by a numeric code or an alphanumeric code.

Subsequently, in method step c), provision is made of a remote data connection between the communication unit and the central unit, by means of which the charging station identity code and the user identity code are transmitted from the communication unit to the central unit. In the central unit, an authentication of the transmitted identity codes takes place in a subsequent method step d). In this authentication, preferably one of the transmitted charging station identity codes is assigned to a matching charging station identity code stored in the database, thereby providing the corresponding associated charging units and unit prices and, on the other hand, an existing authorization of the user for the use of the charging station is made.

After successful authentication, an activation code is generated by the central unit. The activation code is provided, for example, as a numerical code or as an alphanumeric code, which among other things contains information about the released accounting units.

In the further method step e) a transfer of the generated activation code from the central unit to the communication unit takes place subsequently, by means of the remote data connection.

Preferably, in step f), a storage of the number of released billing units and associated unit prices in the database is carried out simultaneously. The storage takes place according to the invention in a billing data record, which is further provided by the central unit for further use.

The communication unit transmits the received activation code in method step g) to the control unit of the charging station.

Finally, in step h), a verification of the activation code is carried out by the control unit and the connection element of the charging station is switched on according to the verified activation code.

By means of the verification, the control unit receives, for example, information about the time duration or for what amount of energy the connection element is to be connected. In addition, the control unit may preferably recognize by the verification whether the unlock code has been completely and correctly transmitted.

After the connection element has been connected, the user of the charging station can access the electrical load, preferably by means of a plug connection, to the latter and the selected amount of energy, or a defined amount of energy for the selected time period.

After disconnecting the connection between the consumer and the charging station, the connecting element can be switched off, for example, by the control unit, so that current can no longer be tapped when a consumer is reconnected.

Alternatively, the connection element, after disconnection from the consumer, also be left in the switched-on state, as long as the selected period has not expired or the selected amount of energy has not been completely tapped. This can be relevant if several consumers are to be loaded one after the other. In this way, it is advantageously made possible for the user of the charging station to disconnect the load from the charging station for a short time, without causing the user a disadvantage as a result of a not fully used period of the current pick-up or an incompletely consumed amount of energy.

In an advantageous development of the method, method step a) is preceded by an additional method step a0). In method step a0), according to the invention, the charging station data set or parts of the charging station data record are created in the database of the central unit by means of a further remote data connection. The further remote data connection is thereby preferably initialized by an operator of the charging station and according to the invention serves to register the charging station in the database and to allocate therein the associated accounting units as well as unit prices.

A further advantageous variant of the method provides that the central unit is assigned a payment module and that a payment process is carried out on the basis of the billing data record.

The payment process relates in this regard to the payment of the selected accounting unit by the user of the charging station and is preferably carried out before performing the method step e).

The payment module can be connected, for example, directly to a credit institution of the charging station operator, so that the payment process by direct debit or credit card method is feasible.

In a particularly advantageous embodiment of the method, the communication unit is connected to the control unit. The communication unit is thus in this case directly connected to the charging station or integrated directly into the charging station.

In this case, preferably immediately after the provision of the NFC connection between the user unit and the control unit in accordance with method step a), the user identity code is transmitted from the user unit to the control unit. Subsequently, the user identity code and the charging station identity code are transmitted in common from the control unit to the communication unit.

The particular advantage of the development listed here is, in particular, that the user unit does not have to have its own communication unit with which a remote data connection to the central unit could be produced. The user unit must thus have only an NFC interface and can therefore be provided with very simple technological means and cost.

A possible implementation variant of such a user unit is, for example, to form it as a chip card with an NFC-enabled RFID element on which the user identification code is stored.

In the event that the communication unit is connected to the control unit, a further advantageous variant of the method provides that before the method step a), a further additional method step a01) is performed. In method step a01), a registration of the potential user of the charging station in the database takes place according to the invention. The registration itself takes place here by entering a user data record, comprising the user identity code and optionally further user data, by the user, for example via the Internet.

Furthermore, in this case, a return information of the user via charging stations registered in the database as well as associated charging units and unit prices preferably takes place before the method according to the invention is carried out. For example, in this case, the potential user of the charging station can use the database to obtain information about available charging stations and the specified charging units and unit prices and then select and activate a charging station for the supply of its electrical load.

Alternatively, a preferred development of the method provides that the communication unit is connected to the user unit so that a direct communication between the user unit and the central unit can be provided via the remote data connection.

This makes it possible according to the invention that the user identity code can be transmitted directly from the user unit via the communication unit to the central unit. A separate transfer of the user identity code to the control unit can thus be dispensed with. In this connection, simultaneously with the provision of the NFC connection between the user unit and the charging station, the charging station identity code is transmitted to the user unit and transmitted from the latter via the communication unit together with the user identity code to the central unit.

At the same time it is made possible by the training listed here as a special technological advantage that the user of the charging station can communicate interactively with the database of the central unit.

In the present case, the user unit can be designed, for example, as an NFC- and data-capable smartphone, wherein the access of the user of the charging station to the database is preferably executable via the corresponding app.

The particular technological advantage of the training shown here is in particular that no additional communication unit must be connected to the control unit and that both the NFC connection and the remote data connection can be initialized via a single device.

In this context, for example, the intrinsic range of functions of NFC-capable smartphones can be used particularly advantageously.

In the event that the communication unit is connected to the user unit, a further advantageous embodiment of the method provides that an additional method step c1) is performed before method step d). In this case, in step c1), the respective billing unit and the associated unit price are transmitted from the central unit to the communication unit and from there to the user unit.

In conjunction with the assignment of the communication unit according to the invention to the user unit, the additional method step c1) makes it possible in a particularly advantageous manner for the potential user of the charging station, after receiving the billing unit and the associated unit price, to make a selection as to whether or not to perform the supply operation on it Want to perform base or not.

The selection for carrying out the supply process is carried out in a preferred variant in an additional process step c2). In this case, method step c2) follows method step c1) and provides for transmission of an activation request from the communication unit to the central unit by means of the remote data connection.
