In der Ladesäule sind dann die für die Durchführung des Ladevorgangs wesentlichen Komponenten integriert. Für den Betreiber eines größeren Parkplatzes oder Ladesystems bedeutet dies, dass er für jeden Stellplatz eines Kraftfahrzeugs eine eigene Ladesäule vorsehen muss, um das gleichzeitige Laden mehrerer Kraftfahrzeuge beziehungsweise der Energiespeicher mehrerer Kraftfahrzeuge zu ermöglichen. Zusätzlich muss eine elektrische Anschlussleitung an das örtliche Stromnetz für alle Ladesäulen vorgehalten werden, damit zumindest theoretisch alle Kraftfahrzeuge, die auf dem Parkplatz abgestellt werden, gleichzeitig geladen werden können. Due to safety requirements of the necessary separate hedge typically a so-called wall box, ie a wall connection, and in the public area a charging station is installed with a charging port for the motor vehicle especially for the AC charging. In the charging station then the essential components for carrying out the charging process are integrated. For the operator of a larger parking lot or charging system, this means that he must provide for each parking space of a motor vehicle own charging station to the simultaneous charging of several Allow vehicles or the energy storage of several vehicles. In addition, an electrical connection line must be provided to the local power grid for all charging stations, so that at least theoretically all motor vehicles parked in the parking lot can be charged at the same time.

Jedem Parkplatz ist somit eine Ladeeinheit mit einem Ladeanschluss für das auf dem Parkplatz beziehungsweise Stellplatz abgestellte Kraftfahrzeug vorhanden. Die Ladeanschlüsse sind mit der Zentraleinrichtung verbunden, in welcher die wesentlichen Komponenten, nämlich die Schalteinrichtung und die The charging station according to the invention with the features of claim 1 has the advantage that reduces the number of items and the arrangement and operation of a charging station for multiple vehicles are simplified.

Ladevorgangs für ein Kraftfahrzeug mit einem elektrischen Energiespeicher und einem elektrischen Antriebsmotor ausgebildet. Dazu sind die Schalteinrichtungen 4, 5 durch jeweils eine Stromschiene 11 beziehungsweise 12 mit Ladeeinheiten 13 verbunden. Vorliegend ist jedem Parkplatz jeweils eine Ladeeinheit 13 zugeordnet, sodass alle ordnungsgemäß auf der Abstellfläche 2 abgestellten Kraftfahrzeuge durch die Zentraleinrichtung 3 mit elektrischer Energie versorgt werden könnten. Die Ladeeinheiten 13 weisen jeweils einen Ladeanschluss 14 auf. Dieser ist beispielsweise als Steckdose oder Anschlusskabel ausgebildet, das mit einem Kraftfahrzeug 15, wie in Figur 2 gezeigt, verbindbar ist, um den elektrischen Energiespeicher 16 des Kraftfahrzeugs mit Energie zu versorgen. Alternativ zu der mechanischen Steckverbindung oder Kontaktierung der Ladeanschlüsse 14 ist gemäß einem weiteren Ausführungsbeispiel vorgesehen, dass die Charging process for a motor vehicle formed with an electrical energy storage and an electric drive motor.

In particular the communication and
Absicherung durch die Sicherungseinrichtung 6, welche die Ladevorgänge überwacht und bei Bedarf abbricht, werden zentral verwaltet. Damit verbleibt für den eigentlichen Parkplatz oder Stellplatz nur der Ladeanschluss 14 in Form einer beispielsweise der Steckdose, des Ladekabels und/oder einer Hedging by the security device 6, which monitors the charging processes and terminates if necessary, are managed centrally. This leaves for the actual parking lot or parking space only the charging port 14 in the form of, for example, the socket, the charging cable and / or a
Induktionsladefläche 17. Dadurch wird der wesentliche Aufwand für den Induktionsladefläche 17. This is the essential effort for the

In this case, for example, a differentiated power distribution as needed, for example, depending on state of charge or capacity or different payment models, take place. A phase sequence default in the central device in single-phase charging is preferably carried out with a uniform load distribution. Because usually not all users of the shelf 2 gleichzeigt must be loaded, a total of fewer leads are necessary. It can also parking spaces remain on the shelf 2, which no loading unit 13 is assigned.
Bevorzugt ist die Kommunikationseinrichtung 7 zur drahtlosen Kommunikation mit den Kraftfahrzeugen 15 beziehungsweise den Benutzern ausgebildet. Eine aufwendige Kommunikationselektronik an den einzelnen Stellplätzen entfällt damit. Preferably, the communication device 7 is designed for wireless communication with the motor vehicles 15 or the users. A complex communication electronics at the individual parking spaces is eliminated.
