Abstract

The charging station (1) has a solar module (2) and a charging regulator together forming a unit. Chargeable, removable batteries (5) in an electric vehicle are removed in the charging station. The charging station is fed with solar power and receives additional power from an electrical power network during less solar radiation. The solar power is fed over an electric meter in the power network. A solar generator tracks the sun. The charging station is transported to any location. The batteries are connected in series to produce same voltage for charging the vehicle.

Description

Aufgabe der ErfindungObject of the invention

Zusätzlich zu den umweltfreundlichen, batteriebetriebenen Fahrzeugen einen weiteren Beitrag zu leisten, um weniger Großkraftwerke und damit weniger CO2 zu erzeugen.In addition to the environmentally friendly, battery-powered vehicles to make another contribution to generate less large power plants and thus less CO2.

Außerdem den Menschen, die unabhängig sein wollen, die Möglichkeit zu geben, ihre eigene „Elektro-Tankstelle” erwerben oder bauen zu können.In addition, to give people who want to be independent the opportunity to buy or build their own "electric petrol station".

Stand der TechnikState of the art

Es sind bisher nur Aufladestationen bekannt, die aus dem elektrischen Stromnetz gespeist werden.There are so far only charging stations known to be fed from the electrical grid.

Beschreibung der ErfindungDescription of the invention

Die Erfindung besteht aus einer bestimmten Anzahl von Batterien als Grundausrüstung. Die Anzahl kann so gewählt werden, dass sie in Reihe geschaltet, die gleiche Spannung ergibt, die beim Laden der batteriebetriebenen Fahrzeuge üblicherweise benötigt wird.The invention consists of a certain number of batteries as basic equipment. The number can be chosen to be connected in series, giving the same voltage that is typically required when charging the battery-powered vehicles.

Außerdem besitzt die Station einen Laderegler mit Überlade- u. Tiefentladeschutz in bekannter Weise.In addition, the station has a charge controller with Überlade- u. Deep discharge protection in a known manner.

Des weiteren einen Stecker, der in bekannter Weise in die Steckdose des Elektrofahrzeuges passt. Zwischen dem Stecker und der Aufladestation muss ein Gleichstromschalter angeordnet werden, der nach dem Verbinden des Steckers mit der Steckdose eingeschaltet wird, da die Station zweckmäßigerweise mit Gleichstrom betrieben wird.Furthermore, a plug that fits in a known manner in the socket of the electric vehicle. Between the plug and the charging station, a DC switch must be placed, which is switched on after connecting the plug to the socket, since the station is suitably operated with direct current.

Vorteil der Anlage ist es, dass der Solarstrom nicht wie der Netzstrom in Gleichstrom umgewandelt werden muss, das macht den Laderegler einfacher und billiger.The advantage of the system is that the solar power does not have to be converted into direct current like the mains power, which makes the charge controller simpler and cheaper.

Die Strings der Solarmodule können so ausgelegt werden, dass die Stringspannung der Höhe der in Reihe geschalteten Batterien entspricht, das vereinfacht die Einspeiseregelung, was ein weiterer Vorteil der Anlage gegenüber der wechselstromgespeisten Anlage bedeutet.The strings of the solar modules can be designed so that the string voltage corresponds to the level of the series-connected batteries, which simplifies the feed-in control, which means a further advantage of the system compared to the AC-powered system.
