 Adapter and method for connecting an electrical load to a charging station of a power grid

description

The present invention relates to an adapter for connecting an electrical consumer to a loading station of a power system with simultaneous I ₀ ger involvement of the consumer into an existing charging network.

In principle, these may be any electrical consumers, but in particular consumers of high-performance batteries, such as electric or hybrid vehicles (plug-in vehicle, PIV for short) 15 intended to receive, store and re-use electrical energy from the power grid can feed. However, it is also possible to connect "consumers" who generate electrical energy, e.g. Fuel cells.

Integration in a charging network means that the consumer, when connected to the charging station, is enabled to participate in transactions via the electricity network or in connection with the electricity grid.

In summary, transactions are processes that are carried out via the electricity network, ie in particular products and services that can be obtained or offered via the electricity network or in connection therewith, in particular purchase or purchase, but also sale or sale of electrical energy. System services such as the receipt or delivery of control energy or control power, the influence of a charging or discharging speed and / or a charging or. Discharge time interval or marketing storage capacity.

As charging network finally the system is understood, which the Execution and billing of transactions allows, for example, the identification of the participants, the authorization of the process, the recording of the sales data (eg the load profile), the transmission and processing of the data and the settlement of the sale with all participants. The operators of electricity network and charging network will often be identical, but this is not always necessary as long as there is at least some cooperation or agreement between the operators so that the charging network operator can handle transactions over the power grid.

Load and storage management are important products that can be provided by PIVs. Electricity is an exceptional product that must be available at the desired time and in the desired quantity at the desired time. Over or under supply is not acceptable. It is the task of the electricity industry to maintain this balance of demand (load) and generation (available power plant output) reliably. Load management and storage can make this task much easier. PIVs can store electricity from the power grid in their batteries and consume it at a later time (electrically driven) or feed it back into the power grid. The charging network can specifically control this capability, opening up and marketing the targeted charging of batteries and the storage and re-feeding of electricity as a product.

The charge management unites many individual vehicles into a bulk consumer of electrical energy. The charging network can selectively stop, start or delay the individual charging processes and thus vary the energy consumed by the entire charging system (also referred to as load management). Storage management can combine the batteries that are distributed across many vehicles into one large storage system for electricity, thus specifically creating storage capacity for commercial marketing. Storage management also uses the reintroduction of electricity from the PIV into the power grid (vehicle-to-grid). Memory basically be used for all arbitrage transactions. It can therefore be assumed that storage capacity will in future be traded on energy markets as a supplement to power plant capacity.

The publication DE 69509529 T2 describes a power grid or charging network with a plurality of tap devices each of which is associated with a control device and with a central computer unit. When a consumer registered with the charging network is connected to such a tapping device, a microcomputer integrated in the consumer can communicate with the control device associated with the tapping device. The control devices in turn are in communication with the central consumer unit. In this way, the consumer can be identified by the control device and, upon successful identification, charging or discharging processes can be controlled or regulated by the control device or, if appropriate, by the central computer unit.

However, in order for the consumer to be able to participate in the charging network, all the components must be installed either in the tapping device, the power distribution network or the consumer themselves and still be fully compatible with each other

The object of the invention is therefore to increase the accessibility of electrical energy and to facilitate participation in an existing charging network.

According to a first aspect of the present invention, this object is achieved by an adapter for connecting an electrical load to a public charging station of a power grid with simultaneous involvement of the consumer in a charging network, wherein the adapter is formed separately from the consumer and the charging station and at least a charging station terminal, which is adapted to a releasable energy transfer connection of the adapter with the - A -

Charging station, at least one consumer terminal comprises, which is adapted to produce a detachable energy transfer moderate connection of the adapter with the consumer and an adapter identification device, which is adapted to cooperate with an identification device provided at the 5-station together to the adapter towards the charging station.

The adapter is not installed in the charging station or in the consumer. The adapter is dedicated to a user who is a natural or legal person. It is freely usable by all consumers as long as the adapter is registered as a participant in the charging network. The adapter is basically the consumer both spatially, and commercially independent. A physical connection is only necessary at the time of charging, after which the adapter can be removed and used for other consumers.

A public charge station is a charging station on the public space, such as the loading station of a "charging station". Such public charging stations are typically only supplied with energy, ₂ o if the user of the consumer is registered with the operator of the charging station or of the current network or electricity provider and identifies itself prior to use, so that the transmitted power can be accounted accordingly.

25 There will be an increased demand in the future for the acquisition of electrical

Give energy in public space and thus give it to public charging stations, where the power connection is not personally assigned to the buyer. The need is in particular with the spreading of electric and hybrid vehicles, the electrical energy over a power connection

30 from a charging station (also called plug-in vehicles), increase sharply.

With the adapter according to the invention, various consumers, the do not need to be registered, participate in the loading network.

Furthermore, participation in various charging networks, for example in different countries, is possible if the adapter has corresponding different connections and is registered with the individual charging networks. It is also an agreement between the various charging networks in the manner of a roaming contract, as is common in telephone networks is conceivable.

The adapter may also have various consumer ports to allow consumers of different manufacturers and with different connection systems to participate in the charging network.

Finally, the adapter according to the invention makes it possible to intelligently control or regulate consumers when the consumers themselves do not have the necessary technology.

The adapter identification device may be, for example, a barcode or RFID transponder provided on the adapter. When inserting the adapter into the socket of the charging station, so when connecting the charging station connection with the charging station, for example, a mechanical switch can be actuated, which triggers that provided at the charging station matching reader reads the bar code or the transponder.

However, bidirectional communication can also be provided via suitable communication units to the adapter and charging station, wherein, for example, the charging station sends a signal to the adapter when the adapter is connected, and then sends an identification number assigned to the adapter and registered with the charging network or electricity provider of the power network encrypted or unencrypted transmitted to the charging station in order to identify itself to the charging station, so that the energy transmission connection to the power supply enabled becomes.

In the simplest case, the communication for billing and for controlling transactions can take place directly between the charging station and the charging network, in many cases the operator of the charging station or the power network and the operator of the charging network can be identical or cooperate closely.

In order to enable billing via the adapter, the adapter can also be provided with a metering device, eg. B. in the form of a smart meter, for receiving transaction data and a charging network communication device, which is formed at least for a data transfer from the adapter to the charging network. In this way, participation in the charging network is also possible via simpler charging stations.

According to a preferred embodiment, the charging network communication device may be configured for bidirectional communication between the adapter and the charging network, and the adapter may further comprise a transaction controller adapted to perform transactions between the charging station and the consumer in accordance with charging network instructions to control or regulate.

Such an adapter allows, for example, a time-controlled charging or discharging, so that charging processes can be carried out precisely at the times when the electricity price is particularly favorable. Likewise, it is possible to obtain and dispense control energy and control power or so-called demand side management, in which charging processes of the consumer can be interrupted or stopped at least temporarily if short-term imbalances in power generation or in power consumption and / or in the power grid occur are.

An adapter with all these features is also suitable for attending Charging network at a charging station in non-public space, that is a charging station, which has its own counter and a specific person (hereinafter referred to as responsible for the charging station) is permanently assigned. At such a non-public charging station electricity is usually removed immediately, without a prior identification of the consumer would be necessary, for example, in sockets in normal homes or garages. However, not all features described above are necessary for this purpose.

According to a second aspect of the present invention, the object of increasing participation in an existing charging network is also solved by an adapter for connecting an electrical load to a non-public charging station of a power network while integrating the load into a charging network, the adapter being separate is formed by the consumer and the charging station and the adapter comprises at least one charging station terminal, which is adapted to produce a detachable energy transfer connection of the adapter with the charging station, at least one consumer terminal, which is adapted to a releasable energy transfer connection of the adapter with the consumer, comprises a charging network communication device adapted at least for the reception of data from the charging network and comprising a transaction control device, which includes The aim is to control or regulate transactions between the charging station and the consumer in accordance with instructions of the charging network.

The charging station does not have to be registered with the charging network. For example, the consumer can take part in the charging network via the adapter at each charging station that is to be used legally. For example, the adapter can be used at a home connection assigned to the user. In this case, the socket does not need to be registered, as the household meter can be used as a reference point for all billing. Charging stations could also be offered through a broker, eg the employer of a user. the.

A simple application, which is possible with such an adapter according to the invention, is to use a simple timer function with which a consumer can be time-charged to load or unload. As mentioned above, it is also possible to use particularly favorable electricity tariffs for preferred times. In this case, the adapter or the user of the consumer need not necessarily be identified, since such a non-public charging station is usually located in an area in which unauthorized persons have no access.

In the simplest case, the transactions can be billed via the counter associated with the charging station, for example the house meter.

Further transactions and billing via the adapter is possible if the adapter further comprises a counter device for receiving transaction data and the charging network communication device is also designed for bidirectional data transfer between the adapter and the charging network, so that also data from the adapter to the charging network can be transmitted.

Furthermore, both for charging in public space and for charging in non-public space, it is possible for an adapter as described above to further include a charging station identification device which is designed to be connected to one of the charging stations Charging station provided identification device cooperate to identify the charging station relative to the adapter. This aspect and its subsequent embodiments can be generalized, for. As in the case that a corresponding adapter electronics is integrated into the consumer, so as an electric vehicle such a charging station identification device directly includes, and thus without a separate adapter to the charging station in question can be connected so that the consumer can identify the charging station. It is possible, for example, for the adapter or, in the generalized case mentioned above, the consumer to identify the charging station to which it is connected and to transmit a corresponding identification code to the charging network, which makes it possible, for example, for various persons to transfer the same charging station to access the same charging network and still be billed individually, of course, there should be a certain basis of trust without identification of the adapter, such as a shared apartment, a hotel, a parking garage or the employer.

In this way, it is also possible to "take along" the own electricity tariff with the adapter even if the adapter is connected to another charging station.

By labeling the charging station (e.g., socket) with, for example, an RFID tag or bar code, ordinary power outlets can also be used to easily and inexpensively integrate any consumer into a charging network when using the adapter of the present invention.

The functionality of the adapter can be extended by further comprising a data memory, preferably a non-volatile but rewritable data memory such as an EPROM, a flash memory or the like. On such a data storage, for example, the adapter identifier, charging network information, transaction data, program code or a credit can be stored, which can be changed in each case according to the purchased or delivered power when using the adapter by connecting a consumer (prepaid electricity).

In order to be able to control or regulate the transactions tailored to the respective connected consumer, for example to adapt charging currents to the consumer specifications or to check the battery status of the consumer. To ask consumers as well as possibly to control the consumer himself, for example, put in a hibernate state, the adapter may further comprise a consumer communication device which is adapted to enable communication between the adapter and the consumer 5 consumers ,

To allow direct control of the load, the adapter may further include a consumer controller.

1NC

According to a preferred refinement, the adapter can be constructed such that the counter and / or the data memory and / or the transaction control device and / or the consumer control / regulating device are exchangeable by the user of the adapter. are.

In particular, the abovementioned devices can be integrated on a single chip or a corresponding card, which is then used in the manner of a SIM card in the adapter, which

Exchange 20 times way. In this way, cards of different charging network providers can alternatively be used in the same adapter, which in particular significantly simplifies the use of such an adapter in various charging networks, for example in different countries. Without this feature, the use of other landing networks is over one

25 cooperation between the charging networks (roaming contracts) is possible.

The transactions controllable or controllable between the charging station and the consumer by use of the adapter according to the invention, in particular controllable or controllable by the transaction control device of the adapter according to the invention, may in particular comprise at least one of the following: Purchase of energy or power, sale or sale of energy or power, purchase or delivery of control energy / control services and other system services (especially for the network), time-controlled charging or discharging of the consumer, demand side management or influencing the charging speed, for example on special request of the user (eg by calling the operator of the charging network).

In order, in particular, to prevent the connection between the adapter and the consumer from being opened by an unauthorized person, who could then connect his own consumer to the adapter and thus obtain electricity on behalf of a third party, the adapter may further comprise a security device , which is designed to, then, when a power transmission connection between the adapter and the consumer is made to secure this connection against unauthorized loosening. This may be, for example, a simple mechanical lock.

In particular, if the adapter comprises an active communication device to identify itself or the charging station, it is advantageous that it further comprises a voltage source, preferably a battery or a rechargeable battery. In this way, the adapter is already functional when loading in public space before it is released by successful identification of the power from the charging station.

In order to facilitate or facilitate the feeding of energy from the consumer into the power grid, the adapter may further comprise an inverter which is designed to supply a DC voltage applied to the load terminal of the adapter to a voltage applied to the charging station terminal of the adapter Convert AC voltage. This means that charging stations with no integrated inverter can be fed with energy into the grid. According to a further embodiment, the adapter may comprise an inverter which converts a DC voltage of a possible DC voltage network at the charging station connection into an AC voltage for a particular AC consumer. delt. In alternative variants of the invention it can also be provided that the adapter contains a transformer.

The above description of the device claims comprises some procedural aspects, so that also in connection with the methods described below, reference is explicitly made to the above description of the devices according to the invention.

In accordance with another aspect of the present invention, the above-described object is achieved by a method of allowing a consumer to participate in a charging network when connected to a public charging station, the method comprising the steps of: connecting the consumer to a charging station Charging station with the interposition of a separately formed by the consumer and the charging station adapter according to one of the preceding claims in combination with claim 1, to allow a power transmission connection between the charging station and the consumer, identifying the adapter to the charging station by means of a on the adapter provided adapter identification device, which cooperates with a corresponding identification device of the charging station, upon successful identification of the adapter enabling the energy transfer connection between the Ladestati and on the consumer, in the event of unsuccessful identification of the adapter, blocking the power transmission connection between the charging station and the consumer, and making transactions between the charging station and the consumer if the identification of the adapter was successful.

With the method according to the invention, unregistered consumers who are not tuned to the charging station or charging network can easily participate in an existing charging network.

An extended functionality is made possible by the method further comprising the following steps: picking up transaction data from a a counter provided on the adapter, transmitting at least part of the transaction data or data derived from the transaction data from a charging network communication device provided to the adapter to the charging network and billing the transactions between a user of the charging device and an operator of the charging station via the charging network.

Furthermore, active control of the consumer may be further facilitated by the method further comprising the steps of: transmitting control data from the charging network to the charging network communication device and controlling transactions between the charging station and the consumer based on the transferred control data by a transaction control device provided on the adapter.

Regarding non-public room charging, the above-described object according to another aspect of the present invention is achieved by a method of enabling a consumer to participate in a charging network when connected to a non-public charging station, comprising the steps of: connecting the consumer to a charging station interposing an adapter according to one of the preceding claims in combination with claim 4 to enable a power transmission connection between the charging station and the consumer, transferring control data from the charging network to a charging network communication device provided on the adapter and controlling Transactions between the charging station and the consumer based on the transmitted control data through a transaction control device provided on the adapter.

The transactions in which the consumer can participate according to the method according to the invention can be at least one of the following: purchase or purchase of energy, sale or sale of energy or power, purchase or transfer of control energy / regulation performance and other system services as well as time-controlled charging and discharging of the consumer, demand side management as well as an influence on the charging speed.

In the following, the present invention will be described with reference to several preferred embodiments shown in the attached Figures 1 to 5.

FIG. 1 shows a schematic representation of a first exemplary embodiment of the adapter according to the invention for charging in public space.

Figure 2 shows a schematic representation of a second embodiment of the adapter according to the invention for loading in public space.

Figure 3 shows a schematic representation of a third embodiment of the adapter according to the invention for loading in public space.

Figure 4 shows a schematic representation of a fourth embodiment of the adapter according to the invention for loading in non-public space.

Figure 5 shows a schematic representation of a fifth embodiment of the adapter according to the invention for loading in a non-public space.

All figures are highly schematic and simplified representations of the adapter according to the invention.

Reference is now made to Figure 1, which shows a first embodiment of the present invention in the form of an adapter 20. The adapter 20 has a charging station connection 4b and a consumer connection 4c in the form of plug-in connection elements which are designed to produce a connection of the adapter 5 with a charging station 30 and a load 10 in an energy-transmitting manner.

The adapter 20 can be designed so that it can accommodate different connections via the terminals 4b and 4c. So consumers can participate in the charging network iö with different connectors, or via the adapter can participate in appropriate registration or cooperation (roaming) of consumers to charging networks with different standard connection connections (such as in different countries).

A communication unit provided on the adapter 20 serves as an adapter identification device 5. By transmitting an adapter identifier to a corresponding communication unit provided on the charging station as identification device 3, the adapter can be identified with respect to the charging station.

20

The data transmission can be carried out as a radio transmission or via a data line, including, for example, the conductive connection can be used, which arises when connecting the adapter to the charging station.

25

As an alternative to the communication device shown, the adapter 20 can also be equipped with a simple bar code or RFID tag as adapter identification device, which can be read by a corresponding reading device at the charging station.

30

The illustrated in Figure 1 public charging station 30 may, for. B. be connected via a 230 V AC or 400 V three-phase connection to the power grid 1, which indicated in the figure by a connecting line is. It should be noted that, if necessary, other connections, such. B. high performance connections can be used.

The charging station 30 further comprises a connection 4a which is compatible with the charging station 4b of the adapter 20, the abovementioned communication unit as an identification device 3, and a switch 2 which, upon successful identification of the adapter 20, provides a power transmission connection from the power network 1 to the terminal 4a of the charging station and thus the adapter 20 can unlock. lö

The consumer 10, indicated here by a connecting cable, can be connected to the adapter 20 via the plug 9. The connection is made via the consumer connection 4c of the adapter 20 and the compatible connection 4d of the plug 9.

15

In order to ensure the security of the energy transfer at all times, a voltage should only be applied to the connection 4a of the charging station when the adapter 20 is connected both to the charging station and to the consumer 10. In an interruption of the connection 20, the voltage supply is interrupted by the switch 2. Connections, adapters and cables should comply with current safety regulations.

In order to avoid abuse, the adapter 20 may be connected to the consumer 10 25 via a fuse unit 8. This can be done in various ways, eg. B. as a mechanical lock closure. The connection to the charging station 30 usually requires no further assurance, since the charging station has its own switch 2 to protect against misuse. 0

As soon as the adapter 20 is connected to the charging station 30 and possibly to the consumer 10 via the plug 9, the identification of the charging station 30 and of the adapter 10 is carried out via the communication units 3 and 5 (eg via an RFID or data connector in the charging station 30 and the adapter 20). Communication connections are indicated in the figures by dashed double arrows. When the authorization of the adapter 20 has taken place, the access to the power grid 1 is enabled by the switch 2.

The transactions, e.g. As the measurement of a load profile in power sales are received by the counter unit 6. The transaction data may be retrieved at any time from the charging network communication device (mobile radio unit) 7 from the adapter 20 to the central charging management and billing system, i. be transferred to the charging network 11. Signals may also be transmitted from the charging network 11 to the charging network communication device 7 at any time.

The charging network communication device 7 may include a data storage 72 and a voltage source 74 (a rechargeable battery) that may be used by all components of the adapter 20. However, the arrangement of the data memory 72 and the voltage source 74 within the adapter 20 can be chosen freely, they need not be associated with the charging network communication device 7.

The transactions can then be billed between the charging network 11 with the user of the consumer 12 and the person responsible (operator) of the charging station 13.

Figure 2 shows a second embodiment of an adapter according to the invention.

In general, the components in the following Figures 2, 3, 4 and 5, which correspond to components of the first embodiment of Figure 1, provided with reference numerals by adding the number 100, 200, 300 and 400 from the reference numerals of the corresponding components in Figure 1 emerge. The further exemplary embodiments are only discussed insofar as they differ from the exemplary embodiment illustrated in FIG. 1 or a previously described exemplary embodiment, to the description of which reference is otherwise expressly made.

As shown in FIG. 2, the adapter 120 may also be completely integrated into a charging cable 132. The cable 132, which is aligned both with the charging station 130 and with the consumer 110, and the adapter 120 are here a common product formed separately from the consumer 110 and the charging station 130.

Furthermore, an inverter 121 is provided on the adapter 120, which converts the DC voltage present at the load terminal 104c, which is supplied for example by the battery of a PIV, into AC voltage present at the charging station connection 104b of the adapter 120, which can be fed into the power grid 101.

In FIG. 3, the illustrated adapter 220 is additionally provided with a transaction control device 214, which enables the adapter 220 to implement instructions of the loading network 211.

The adapter can also be equipped with a communication unit 215 to the consumer side. If the consumer 210 is also equipped with a communication unit 216, the consumer 210 can also receive information from a central charge management and billing system (charging network) 211 via the adapter 220 according to the invention and implement it within the scope of its technical possibilities. The communication unit 215 thus also serves as a consumer control / regulating device 217.

The adapter according to the invention in all dargestellen embodiments will initially primarily handle the sale of electrical energy to the user, but such an adapter can also control other transactions and bill it if the consumer allows it. For example, the adapter can control the loading and unloading of the battery in an electric or hybrid vehicle. The accumulator of the consumer could thus be marketed commercially.

Figure 4 shows an embodiment of an adapter according to the invention, more specifically an adapter 320 for loading in non-public space.

The illustrated non-public charging station 330 includes a counter 317 that provides various services, e.g. Sales of electricity or load can capture. The switch and the communication unit of the charging station can be omitted when loading in non-public space.

Likewise, an identification of the adapter via the communication units (3 and 5 in FIG. 1) and the activation of the power supply can be dispensed with. Access to the power grid at the non-public charging station is usually always enabled.

The adapter 320 is equipped with control technology, in particular a transaction controller 314, for implementing instructions of the charging network 311 which the adapter 320 can receive via the charging network communication device 307. For example, charging processes can be time-controlled via the adapter 320 so that charging takes place only at times with particularly favorable electricity prices, as long as the charging network 311 has the necessary information about the electricity tariffs. The charging network 311 should therefore know the conditions of the current connection of the charging station 330 in order to optimize the transactions commercially for the user.

The transactions may be handled between the charging network 311 and the user 312 of the consumer 310. The person in charge of the charging station 313 (ie the person to whom the meter is assigned) can, but does not necessarily have to be involved in this process but can do so from the counter 317 recorded transactions with the operator of the charging station 330 also charge independently. Normally, however, the user and the person responsible for the charging station 330 are the same person.

The connection to the charging station 330 is to be protected against misuse by the person in charge of the charging station 330 (eg by closing the garage).

The adapter 420 shown in FIG. 5 differs from the adapter 320 shown in FIG. 4 in that, like the adapter 120 from FIG. 2, the adapter 420 is also integrated in a charging cable 432. Furthermore, an inverter 421 is also provided in the adapter 420. However, it is also possible to dispense with the adapters 420 or 120 to the inverter, as well as to provide an inverter to the other illustrated adapters.
