Description
In Parkeinrichtungen, wie zum Beispiel Parkhäusern werden zunehmend Ladeanschlüsse für mobile Energiespeicher, insbesondere Automobile, aber auch Fahrräder bereitgestellt. Insbesondere bei bestehenden Parkeinrichtungen, aber auch bei neuerstellten Parkeinrichtungen, ist die vom Versorgungsnetz zur Verfügung gestellte maximale Leistung auf einen vorgegebenen Maximalwert begrenzt. Die zunehmende Durchdringung an Elektromobilität, insbesondere die Schnellladetechnologien (Schnellladesäulen) stellen die Betreiber von diesen Parkeinrichtungen vor Herausforderungen, wenn sie bei einer vorgegebenen maximalen elektrischen Leistung eine möglichst große Anzahl von Ladevorrichtungen für Elektroautos zur Verfügung stellen wollen.In parking facilities, such as multi-storey car parks, charging connections for mobile energy storage devices, in particular automobiles, but also bicycles, are increasingly being provided. In the case of existing parking facilities in particular, but also for newly created parking facilities, the maximum power made available by the supply network is limited to a predetermined maximum value. The increasing penetration of electric mobility, in particular fast charging technologies (fast charging stations), pose challenges for the operators of these parking facilities if they want to provide the largest possible number of charging devices for electric cars at a given maximum electrical output.
Insbesondere stößt die Integration von Schnellladestationen (Schnellladeanschlüsse) aufgrund des enormen gleichzeitigen Leistungsbezuges und der damit verbundenen hohen Leistungsbezüge schnell an seine Grenzen. Hieraus resultiert häufig, dass weder viele Schnellladestationen noch genügend andere Ladestationen mit geringerer Ladeleistung in die Parkeinrichtungen integriert werden können. Die Anzahl von möglichen Schnellladestationen ist von der vorgegebenen maximalen elektrischen Leistung des Parkhauses und der Leistung einzelner Ladesäulen abhängig und wird konventionell für den Gleichzeitigkeitsfaktor 1 bestimmt. In der Realität ist jedoch die zeitliche Ausnutzung von Schnellladestationen nicht bekannt und die Fahrzeuge werden häufig nicht direkt nach vollständiger Ladung von der Schnelladesäule abgezogen. Außerdem weisen Fahrzeuge, die an Ladestationen geladen werden, nur für relativ kurze Zeit den maximalen Leistungsbedarf auf, der Leistungsbezug sinkt nach einem kurzen Peak mit dem Maximalwert je nach Fahrzeugtyp ab. Die maximale Ladeleistung für die Schnellladestationen muss jedoch dauerhaft vorgehalten werden, was die Anzahl an übrigen Nebenladestationen bzw. Nebenladeanschlüssen reduziert. Daraus folgt, dass die Anzahl der möglichen Ladeanschlüsse bzw. Ladesäulen sich aus dem Quotienten der Anschlussleistung aus dem Versorgungsnetz und der maximalen an den Ladeanschlüssen anliegenden Ladeleistung ergibt. Wenn man beispielsweise davon ausgeht, dass einer Parkeinrichtung 600 kW an Anschlussleistung zur Verfügung stehen und drei Schnellladesäulen vorgesehen sein sollen, die jeweils 150 kW Ladeleistung garantieren, so kann für Nebenladestationen lediglich summarisch ein Restwert von 150 kW Leistung zur Verfügung gestellt werden. Diese restlichen 150 kW werden nun zu konstanten Bruchteilen von in der Regel 10 kW pro Nebenanschluss auf die restlichen Nebenladesäulen gleichmäßig verteilt, was dazu führt, dass für das gesamte Parkhaus nur 15 weitere Nebenladeanschlüsse vorgesehen werden können. Dies bedeutet eine höchst ineffektive Auslastung der zur Verfügung stehenden Leistung und mindert die Wirtschaftlichkeit des Betriebes des Parkhauses sehr.In particular, the integration of fast charging stations (fast charging connections) quickly reaches its limits due to the enormous simultaneous power consumption and the associated high power consumption. This often results in the fact that neither many fast charging stations nor enough other charging stations with lower charging power can be integrated into the parking facilities. The number of possible fast charging stations depends on the specified maximum electrical power of the parking garage and the power of individual charging stations and is conventionally determined for a simultaneity factor of 1. In reality, however, the temporal utilization of fast charging stations is not known and the vehicles are often not withdrawn from the fast charging station immediately after they have been fully charged. In addition, vehicles that are charged at charging stations only have the maximum power requirement for a relatively short time; the power consumption drops after a short peak with the maximum value depending on the vehicle type. However, the maximum charging power for the fast charging stations must be kept permanently available, which reduces the number of other auxiliary charging stations or auxiliary charging connections. It follows from this that the number of possible charging connections or charging stations results from the quotient of the connection power from the supply network and the maximum charging power applied to the charging connections. If one assumes, for example, that a parking facility has 600 kW of connected load and three fast charging columns are to be provided, each guaranteeing 150 kW of charging power, a residual value of 150 kW of power can only be made available for secondary charging stations. The remaining 150 kW are now evenly distributed to the remaining auxiliary charging stations in constant fractions of usually 10 kW per auxiliary connection, which means that only 15 additional auxiliary charging connections can be provided for the entire car park. This means a highly ineffective utilization of the available power and greatly reduces the profitability of the operation of the parking garage.
Die Aufgabe der Erfindung besteht darin, eine Ladeinfrastruktur für mobile Energiespeicher zur Verfügung zu stellen, die es erlaubt, neben Schnellladeanschlüssen Nebenladeanschlüsse wirtschaftlicher als im Stand der Technik zu betreiben. Ferner besteht die Aufgabe darin, ein entsprechendes Verfahren zur Verfügung zu stellen.The object of the invention is to provide a charging infrastructure for mobile energy storage devices which, in addition to fast charging connections, allows auxiliary charging connections to be operated more economically than in the prior art. Furthermore, the task is to provide a corresponding method.
Die Lösung der Aufgabe besteht in einer elektrischen Ladeinfrastruktur mit den Merkmalen des Patentanspruchs 1 sowie ein Verfahren zum Betreiben einer elektrischen Ladeinfrastruktur mit den Merkmalen des Patentanspruchs 9.The object is achieved in an electrical charging infrastructure with the features of claim 1 and a method for operating an electrical charging infrastructure with the features of claim 9.
Die elektrische Ladeinfrastruktur für mobile Energiespeicher weist dabei eine elektrische Schnittstelle zu einem Versorgungsnetz auf. Ferner umfasst sie ein Ladenetz zur Verteilung einer aus dem Versorgungsnetz eingespeisten elektrischen Nennleistung
Unter dem Begriff kontinuierlich zu ermitteln, wird dabei verstanden, dass durch den Netzleistungsregler stetig die zur Verfügung stehende Leistung abgefragt wird und eine Umverteilung der an den Nebenanschlüssen zur Verfügung gestellten Leistung in diskreten Zeitintervallen erfolgt. Diese Zeitintervalle sind in der Regel kürzer als zehn Minuten, sind insbesondere kürzer als eine Minute bevorzugt im Bereich von zehn Sekunden und weniger. Eine tatsächlich kontinuierliche Messung anstatt der vereinfachten Messung in diskreten Zeitintervallen kann in verschiedenen Messeinrichtungen auch zweckmäßig sein.The term "continuously ascertaining" means that the power available is continuously queried by the network power regulator and the power made available at the auxiliary connections is redistributed at discrete time intervals. These time intervals are generally shorter than ten minutes, are in particular shorter than one minute, preferably in the range of ten seconds and less. An actually continuous measurement instead of the simplified measurement in discrete time intervals can also be expedient in various measuring devices.
Schnellladeanschlüsse werden dabei in der Regel mit höherer Leistung versorgt als Nebenladeanschlüsse. Sie sind in höhere Leistungsklassen angeordnet und werden in den Nebenladeanschlüssen vorrangig mit elektrischer Energie versorgt. Der Leistungsflussregler gibt dabei Informationen über die zur Verfügung stehende Leistung, die er von den Schnellladeanschlüssen erhält, an die Nebenanschlüsse weiter. Es wird dabei jedem Nebenladeanschluss in einer Einzelfestlegung die Leistung zugewiesen, die der Anschluss freigeben darf. Die Steuerung hierfür liegt entweder im Nebenladeanschluss selbst, sie wird jedoch in der Regel von der Leistungselektronik des zu ladenden mobilen Energiespeichers, also vom Fahrzeug durchgeführt.Fast charging connections are usually supplied with higher power than auxiliary charging connections. They are arranged in higher performance classes and are primarily supplied with electrical energy in the auxiliary charging connections. The power flow controller forwards information about the available power, which it receives from the fast charging connections, to the auxiliary connections. It will do everyone The auxiliary charging connection is assigned the power that the connection is allowed to release in an individual specification. The control for this is either in the auxiliary charging connection itself, but it is usually carried out by the power electronics of the mobile energy storage device to be charged, i.e. by the vehicle.
Durch die beschriebene Lehre des Patentanspruchs 1 wird es ermöglicht, flexibel auf den variierenden Leistungsbedarf der Schnellladeanschlüsse zu reagieren und die zu einem bestimmten Zeitpunkt zur Verfügung stehende Restleistung, also der Anteil der vom Versorgungsnetz zur Verfügung gestellten Nennleistung
In einer weiteren Ausgestaltungsform der Erfindung ist eine minimale Ladeleistung
Es ist somit möglich, eine minimale Ladeleistung der Nebenladeanschlüsse zu gewährleisten, die bei vielen mobilen Fahrzeugen zum minimalen Ladebetrieb notwendig ist. Es kann also die Anzahl X zu jedem Zeitpunkt t an Nebenladeanschlüssen ausgerechnet werden, die grundsätzlich mit einer minimalen Ladeleistung versorgt werden kann. Diese ergibt sich eben aus der Restladeleistung
Auf diese Art und Weise ändert sich auch die Anzahl X(t) kontinuierlich in Abhängigkeit der Restladeleistung
Ferner ist es zweckmäßig, wenn an den Schnellladeanschlüssen eine Freigabeschaltung vorgesehen ist, die mit dem Leistungsflussregler in Kommunikationsverbindung steht. Diese Freigabeschaltung dient ebenfalls zur kontinuierlichen Freigabe der nicht benötigten Maximalleistung, die einen Schnellladeanschluss garantiert ist. Bei einem üblichen Ladevorgang an einen Schnellladeanschluss wird die maximal zur Verfügung gestellte Ladeleistung lediglich für eine geringe Zeitspanne bzw. einen geringeren Prozentsatz der Gesamtladezeit benötigt. Die Freigabeschaltung kann dabei kontinuierlich die nicht benötige Ladeleistung an die Nebenladeanschlüsse über das Ladenetz weitergeben, wobei eine Information über eine Kommunikationsverbindung an den Leistungsflussregler erfolgt. Der Leistungsflussregler wiederum verteilt dann, wie bereits beschrieben, die Restleistung
Die Freigabeschaltung kann dabei in zweckmäßiger Ausgestaltung auch wiederum Regelbefehle des Leistungsflussreglers enthalten, wodurch die Versorgung der Nebenladeanschlüsse im Nebenladeteilnetz über die Freigabeschaltung in optimierter Weise, durch den Leistungsflussregler geregelt, erfolgt.In an expedient embodiment, the release circuit can also contain control commands from the power flow controller, whereby the supply of the auxiliary charging connections in the auxiliary charging sub-network takes place via the release circuit in an optimized manner, regulated by the power flow controller.
Ein weiterer Bestandteil der Erfindung ist ein Verfahren zum Betreiben einer elektrischen Ladeinfrastruktur für mobile Energiespeicher, wobei die Ladeinfrastruktur über eine elektrische Schnittstelle zu einem Versorgungsnetz einer Nennleistung
Aus dem beschriebenen erfindungsgemäßen Verfahren ergeben sich dieselben Vorteile, die bereits bezüglich der Vorrichtung gemäß Anspruch 1 erläutert werden. Ein wichtiger Vorteil besteht eben darin, dass von den Schnellladeanschlüssen nicht abgerufene Ladeleistung kontinuierlich temporär, also zeitlich ständig veränderbar, auf die Nebenladeanschlüsse verteilt werden kann. Dabei kann die Verteilung an die Nebenladeanschlüsse nicht nur zeitlich verändert, sondern für jeden Nebenladeanschluss in unterschiedliche Höhe individuell verteilt werden. Somit können auch die Anforderungen im Ladeumfeld, was die Belegung der Schnellladeanschlüsse und der Nebenladeanschlüsse angeht, sehr und gezielt reagiert werden, was die Wirtschaftlichkeit der Ladeinfrastruktur gegenüber dem Stand der Technik erhöht.The described method according to the invention results in the same advantages that have already been explained with regard to the device according to claim 1. An important advantage is that charging power that is not called up by the fast charging connections can be distributed to the auxiliary charging connections continuously and temporarily, that is to say can be constantly changed over time. The distribution to the auxiliary charging connections can not only be changed over time, but can also be distributed individually at different levels for each auxiliary charging connection. In this way, the requirements in the charging environment with regard to the occupancy of the fast charging connections and the auxiliary charging connections can also be responded to in a very and targeted manner, which increases the cost-effectiveness of the charging infrastructure compared to the state of the art.
In einer weiteren Ausgestaltungsform der Erfindung zeichnet sich das Verfahren dadurch aus, dass eine minimale Ladeleistung
Hierdurch wird sichergestellt, dass jedem Nebenladeanschluss mindestens eine minimale Leistung
Ein weiterer Bestandteil der Erfindung besteht darin, dass gemäß dem Verfahren eine Freigabeschaltung vorgesehen ist, an die vom Leistungsflussregler Regelbefehle zur Freigabe der Restladeleistung
Weitere Ausgestaltungsformen der Erfindung und weitere Merkmale werden anhand der vorliegenden Figuren näher beschrieben. Dabei handelt es sich um rein exemplarische Ausgestaltungsformen, die sehr schematisch dargestellt sind, die keine Einschränkung des Schutzbereiches darstellen.Further embodiments of the invention and further features are described in more detail with reference to the present figures.
