Charging device having the following features: at least a first charging circuit for generating a first charging current and a second charging circuit for generating a deviating from the first charging current second charging current; at least a first charging port for coupling the charging device to a first electric vehicle and a second charging port for coupling the charging device to a second electric vehicle; and at least one first switching unit configured to switch the first charging port between the first charging circuit and the second charging circuit to select a charging current for the first electric vehicle, and a second switching unit configured to select a charging current for the second electric vehicle to switch the second charging connection between the first charging circuit and the second charging circuit.
Unter einem Elektrofahrzeug kann ein batteriegetriebenes Kraftfahrzeug verstanden werden, dessen Batterie, beispielsweise ein Lithium-Ionen- Akkumulator, mit der Ladevorrichtung gekoppelt werden kann. Die An electric vehicle can be understood as a battery-powered motor vehicle whose battery, for example a lithium-ion accumulator, can be coupled to the charging device. The
Ladevorrichtung kann beispielsweise als Ladesäule auf einer Parkfläche für mehrere Elektrofahrzeuge realisiert sein. Unter einer Ladeschaltung kann eine elektrische Schaltung zum Erzeugen eines Ladestroms verstanden werden. Unter einem Ladeanschluss kann eine Schnittstelle zum elektrisch leitfähigen Verbinden der Ladevorrichtung mit dem Elektrofahrzeug verstanden werden. Beispielsweise kann der Ladeanschluss als Stecker- oder buchsenförmiges Verbindungselement ausgebildet sein, das mit einer entsprechenden Steckeroder Buchsenaufnahme des Elektrofahrzeugs elektrisch leitfähig gekoppelt und verriegelt werden kann. Alternativ kann der Ladeanschluss ausgebildet sein, um eine Batterie des Elektrofahrzeugs berührungslos, d. h. induktiv, zu laden. Unter einer Schalteinheit kann ein elektronisches Bauelement mit einem oder mehreren Schaltern, beispielsweise ein Schütz oder ein Leistungstransistor, verstanden werden. Der vorliegende Ansatz beruht auf der Erkenntnis, dass eine Ladevorrichtung für Elektrofahrzeuge mehrere Ladeanschlüsse zum gleichzeitigen Anschließen mehrerer Fahrzeuge an die Ladevorrichtung aufweisen kann, wobei die Charging device can be realized for example as a charging station on a parking area for several electric vehicles. A charging circuit may be understood to mean an electrical circuit for generating a charging current. A charging connection can be understood as meaning an interface for the electrically conductive connection of the charging device to the electric vehicle. For example, the charging port may be formed as a plug or socket-shaped connecting element, which can be electrically conductively coupled and locked with a corresponding plug or socket receptacle of the electric vehicle. Alternatively, the charging connection can be designed to charge a battery of the electric vehicle without contact, ie inductively. A switching unit can be understood to mean an electronic component having one or more switches, for example a contactor or a power transistor. The present approach is based on the finding that an electric vehicle charging device may have a plurality of charging ports for simultaneously connecting a plurality of vehicles to the charging device, wherein the
Ladeanschlüsse je mit unterschiedlichen Ladeströmen beaufschlagt werden können. Charging connections can each be acted upon with different charging currents.
Dadurch ist es möglich, mehrere Batterien sequenziell, intermittierend oder mittels anderer geeigneter Zeitscheibenverfahren aus einer geringeren Anzahl von Ladeschaltungen zu laden, um Hardwareaufwand und damit Kosten einzusparen sowie die Verfügbarkeit von Lademöglichkeiten für potenzielle Verbraucher zu erhöhen. This makes it possible to charge several batteries sequentially, intermittently or by means of other suitable time slicing methods from a smaller number of charging circuits in order to save hardware and thus costs as well as to increase the availability of charging options for potential consumers.
Ein weiterer Vorteil besteht darin, dass aus einer Auswahl verfügbarer Another advantage is that from a selection of available
Ladeschaltungen verschiedener Leistungsklassen jeweils eine für einen aktuellen Ladeabschnitt geeignete bzw. ausreichende Ladeschaltung ausgewählt werden kann, um eine verfügbare Leistung optimal auf einen Bedarf der Charging circuits of different power classes each one suitable for a current charging section or sufficient charging circuit can be selected to optimize an available power to a demand of
angeschlossenen Verbraucher zu verteilen. distributed consumers.
Darauf aufbauend lässt sich auch ein Bedienkomfort erhöhen, indem mittels der Ladevorrichtung gemäß einer nachfolgend beschriebenen Ausführungsform Komfortfunktionen wie eine Priorisierung der Ladevorgänge, etwa als Based on this, operating comfort can also be increased by using the charging device according to an embodiment described below to provide comfort functions such as prioritization of the charging processes, for example as
aufpreispflichtige Features, realisiert werden können. features subject to additional charge, can be realized.
Der Statistik nach wird ein privates Fahrzeug im Schnitt nur etwa eine Stunde pro Tag bewegt. Zudem geht die Tendenz der Hersteller dahin, die Ladezeiten möglichst kurz zu halten bzw. immer weiter zu verkürzen. Üblich sind daher bereits heute Ladezeiten von nur wenigen Stunden. Da die Parkzeit der According to statistics, a private vehicle is moved on average only about one hour per day. In addition, the tendency of the manufacturers is to keep the loading times as short as possible or to shorten ever further. Therefore, loading times of just a few hours are already common today. As the parking time of the
Elektrofahrzeuge somit üblicherweise eine jeweils benötigte Ladezeit um ein Vielfaches überschreitet, lässt sich die Ladevorrichtung gegenüber Electric vehicles thus usually exceeds a respectively required charging time by a multiple, the charging device can be compared
herkömmlichen Lösungen deutlich wirtschaftlicher betreiben. Es lässt sich zwar nicht verhindern, dass die Parkzeit die Ladezeit um ein Vielfaches überschreitet, es lässt sich jedoch verhindern, dass die Ladeeinrichtung in der Zwischenzeit nicht von anderen Teilnehmern genutzt werden kann. Durch den zunehmenden Anteil von Elektro- oder Hybridfahrzeugen an der Verkehrsflotte dürfte die Nachfrage nach entsprechenden Lademöglichkeiten künftig weiter ansteigen. Mittels des vorliegenden Ansatzes kann das operate conventional solutions significantly more economical. Although it can not be prevented that the parking time exceeds the charging time many times, but it can be prevented that the charging device can not be used in the meantime by other participants. Due to the increasing share of electric or hybrid vehicles in the transport fleet, the demand for corresponding charging options should continue to increase in the future. By means of the present approach, the
Ungleichgewicht, das bei den heute eingesetzten statischen Ladeeinrichtungen auftreten kann, vermieden werden und somit einem möglichen Überangebot an nicht nutzbarer Ladeleistung vorgebeugt werden. Imbalance that can occur in the static charging devices used today, be avoided and thus a possible oversupply of unusable charging power can be prevented.

80 Prozent den vollen Ladestrom aufnehmen. Die restlichen 20 Prozent können hierauf in einer zweiten Ladephase mit einer in Relation zur ersten Ladephase deutlich geringeren Leistung über eine entsprechend längere Zeit aufgenommen werden. 80 percent record the full charge current. The remaining 20 percent can then be recorded in a second charging phase with a significantly lower power in relation to the first charging phase over a correspondingly longer time.

Durch diese Ausführungsform kann die Ladevorrichtung mit sehr geringemSupply line and / or the second supply line to interconnect. For example, the third potential may be a ground potential and the common supply line may be a ground line. By this embodiment, the charging device with very little

Dadurch können über eineThe charging device according to another embodiment may include a third switching unit configured to control a current flow through the common supply line. This can be done via a

Switching unit centrally all charging processes of the charger are interrupted. Such a third switching unit for equalizing potentials can be dispensed with in a charging device, for example in the form of a charging station, since the charging station can preset a suitable potential by itself, at least when the potential of the connected subscribers can be measured or if it is the charging station can communicate in any way.

The second switch 245 is configured to reduce a current flow due to the resistor 250 between the third
Gehäuseanschluss 215 und den Ladeanschlüssen 125, 130 zu ermöglichen, wenn der erste Schalter 240 geöffnet ist. Somit kann über die Schalter 240, 245 auf einfache Weise eine Größe einer an den Ladeanschlüssen 125, 130 anliegenden Ladespannung oder eine Größe eines an den Ladeanschlüssen 125, 130 bereitgestellter Ladestroms eingestellt werden.

Beispielhaft ist die in Fig. 2 gezeigte Ladevorrichtung 100 mit zwei weiteren Ladeanschlüssen 260 ausgeführt, die analog zu den Ladeanschlüssen 125, 130 über je eine weitere Schalteinheit 265 mit der ersten Versorgungsleitung 220 oder der zweiten Versorgungsleitung 225 verschaltbar sind. Die weiteren Ladeanschlüsse 260 sind ferner über die gemeinsame Versorgungsleitung 230 und die dritte Schalteinheit 235 mit dem dritten Gehäuseanschluss 215 verbunden. By way of example, the charging device 100 shown in FIG. 2 is designed with two further charging connections 260, which can be connected to the first supply line 220 or the second supply line 225 via a respective further switching unit 265 analogously to the charging connections 125, 130. The further charging connections 260 are furthermore connected to the third housing connection 215 via the common supply line 230 and the third switching unit 235.
Die Ladevorrichtung 100 umfasst optional ferner eine Steuereinrichtung 270, die mit den Schalteinheiten 115, 120, 235, 265 verbunden ist und ausgebildet ist, um eine Information über einen Ladezustand und/oder eine vorgegebene Ladezeit eines an den Ladeanschlüssen 125, 130, 260 anschließbaren Elektrofahrzeugs zu empfangen und die Schalteinheiten 115, 120, 235, 265 in Abhängigkeit von der Information anzusteuern.

Gemäß einem Ausführungsbeispiel ist die Ladevorrichtung 100 mit zwei unterschiedlichen Ladeschaltungen 105, 110 und mehreren Ladeanschlüssen 125, 130, 260 in Form von Ladebuchsen ausgeführt, wobei die erste According to an exemplary embodiment, the charging device 100 is designed with two different charging circuits 105, 110 and a plurality of charging connections 125, 130, 260 in the form of charging sockets, the first one being in the form of charging sockets
Ladeschaltung 105 als Hochstromladeeinheit mit einer hohen Ausgangsleistung und die zweite Ladeschaltung 110 als Niedrigstromeinheit mit einer niedrigen Ausgangsleistung vorgesehen ist. Dies hat den Vorteil, dass für die nicht hochstromfähige Ladeschaltung 110 ein geringerer Hardwareaufwand erforderlich ist. Somit können Teilnehmer im niedrigen SOC-Bereich am Hochstromlader 105 geladen werden und anschließend mittels des kleineren Laders 110 vollgeladen werden. Dabei können die Teilnehmer gleichzeitig angeschlossen werden und sequenziell ohne Benutzereingriff geladen werden. Optional ist eine Priorisierung der zu ladenden Teilnehmer vorgesehen. Charging circuit 105 is provided as a high-current charging unit with a high output power and the second charging circuit 110 is provided as a low-current unit with a low output power. This has the advantage that less hardware expenditure is required for the non-high-current charging circuit 110. Thus, subscribers in the low SOC range may be charged to the high current loader 105 and subsequently fully charged by the smaller loader 110. The participants can be connected simultaneously and be loaded sequentially without user intervention. Optionally, a prioritization of the participants to be loaded is provided.
Beispielsweise können ladeausgangsseitig statt nur jeweils eines einzelnen Schützes mehrere Schütze eingesetzt werden, entsprechend der Anzahl an Ladebuchsen, die das Terminal einem Verbraucher bereitstellen soll. Über eine Verbindung zu den Ladeschaltungen 105, 110 kann kommuniziert werden, um Ladestrom und -Ladespannung einzustellen. For example, instead of just one individual contactor each, several contactors can be used on the load output side, corresponding to the number of charging sockets the terminal is to provide to a consumer. Through a connection to the charging circuits 105, 110 can be communicated to adjust charging current and charging voltage.
Die Ladeanschlüsse 125, 130, 260 können als Teile eines Stecksystems ausgebildet sein. Wird ein Fahrzeug zur Ladung angeschlossen, so wird das Stecksystem sowohl durch das Fahrzeug als auch durch einen jeweiligen Ladeanschluss mechanisch verriegelt, um ein unbefugtes Unterbrechen der Verbindung zu verhindern. Ein derart verriegelter Ladeanschluss ist somit für andere potenzielle Nutzer blockiert, unabhängig davon, ob tatsächlich ein Ladevorgang stattfindet oder nicht. The charging ports 125, 130, 260 may be formed as parts of a plug-in system. When a vehicle is connected for charging, the connector system is mechanically locked by both the vehicle and a respective charging port to prevent unauthorized disconnection. Such a locked charging port is thus blocked for other potential users, regardless of whether charging actually takes place or not.
Die Ladevorrichtung 100 kann in analoger Weise auch mit induktiven The charging device 100 can also be used in an analogous manner with inductive
Lademethoden vorgesehen sein, wobei sich im Vergleich zu einer Loading methods are provided, in comparison to a
Ausführungsform mit Steckverbindung lediglich das Übertragungsmedium bzw. die Schnittstelle zwischen Energiespender und -empfänger ändert. Gemäß einem Ausführungsbeispiel ist eine Ladesäule mit zwei gleichen Embodiment with connector only the transmission medium or the interface between the energy donor and receiver changes. According to one embodiment, a charging station with two is the same
Ladeschaltungen und mehreren Ladebuchsen vorgesehen. Ein Vorteil dieser Variante besteht in einer geringen Varianz an Hardwarebauteilen durch identische Hardware für die Ladeschaltung. Auch in dieser Variante können mehrere Teilnehmer gleichzeitig angeschlossen und sequenziell ohne Charging circuits and several charging sockets provided. An advantage of this variant is a low variance of hardware components due to identical hardware for the charging circuit. Also in this variant, several participants can be connected simultaneously and sequentially without
Benutzereingriff geladen werden. Hierbei ist eine Priorisierung der zu ladenden Teilnehmer möglich. User intervention to be loaded. Here, a prioritization of the participants to be loaded is possible.
