Abstract

The switch (4) is bridged by a resistance (13) having a resistance value e.g. of 40 k ohms and a power of 1.5 W, across which a sufficient holding current flows, for the switching on of the fault current plug (5).The holding current is about half the value of the current, determining the risk limit. The switch (4) is open with the flap open and is closed with the flap closed. So that only with a closed flap, the supply voltage of the voltage source (2) is applied at the plug box (3).

Description

Die Erfindung bezieht sich auf eine Ladestation nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a charging station according to the Preamble of claim 1.

Mit Hilfe der Ladestation werden Elektrofahrzeuge mit Bordladegerät wiederaufgeladen. Aus Sicherheitsgründen besitzt das Elektrofahrzeug den Fehlerstromstecker, um beispielsweise im Falle eines beschädigten Zuleitungska­ bels höchstmöglichen Personenschutz zu erreichen. Ande­ rerseits besitzt die Ladestation aus Sicherheitsgründen die Klappe, deren Bewegung mit der Betätigung des Schal­ ters gekoppelt ist. Damit wird verhindert, daß bei geöff­ neter Klappe die Steckdose spannungsführend ist. Die Steckdose führt erst dann Spannung, wenn die Klapptür hier nach Einstecken des Fehlerstromsteckers geschlossen ist. Dabei ist aber durch die dann geschlossene Klappe der Fehlerstromstecker nicht mehr zugänglich und der im Fehlerstromstecker enthaltene Fehlerstromschalter nicht mehr von Hand schließbar. Damit ist es nicht möglich, das Elektrofahrzeug über die Ladestation wiederaufzuladen.With the help of the charging station, electric vehicles are with On-board charger recharged. For safety reasons the electric vehicle has the residual current plug in order for example in the case of a damaged supply cable to achieve the highest possible level of personal protection. Ande on the other hand, the charging station has for security reasons the flap, its movement with the actuation of the scarf ters is coupled. This prevents that when open the outlet is live. The The socket is only live when the folding door closed here after plugging in the residual current plug is. But this is through the closed flap the fault current plug is no longer accessible and the im Residual current switches do not contain residual current plugs more closable by hand. It is not possible with that Recharge the electric vehicle via the charging station.

Der Erfindung liegt die Aufgabe zugrunde, eine Ladesta­ tion der eingangs genannten Art zu schaffen, die es er­ möglicht, unter Beibehaltung der beschriebenen Sicher­ heitsmaßnahmen sowohl auf Seite der Ladestation als auch auf Seite des Elektrofahrzeugs das Elektrofahrzeug wie­ deraufladen zu können.The invention has for its object a charge tion of the type mentioned above, which he possible, while maintaining the described security safety measures both on the side of the charging station and on the side of the electric vehicle the electric vehicle like to be able to charge.

Die Erfindung löst diese Aufgabe durch die kennzeichnen­ den Merkmale des Patentanspruchs 1. The invention solves this problem by characterizing the features of claim 1.  

Bei geöffneter Klappe ist die Steckdose nur soweit strom­ führend wie zum Schalten des Fehlerstromsteckers erfor­ derlich ist. Nach Schließen der Klappe ist der Schalter dann geschlossen und es liegt die volle Ladespannung an der Steckdose an.When the flap is open, the socket is only current enough leading as required for switching the residual current plug is such. After closing the flap is the switch then closed and the full charging voltage is present the socket.

Die obere Grenze für den Fehlerstrom, der bei geöffneter Klappe fließt ist bestimmt durch die Gefährlichkeits­ grenze, die lt. IEC-Report 479 bei etwa 12 mA bei 50 Hz liegt. Es dient der Erhöhung der Sicherheit, wenn der Fehlerstrom nicht gleich diesem Grenzwert, sondern bei­ spielsweise lediglich die Hälfte dieses Wertes ist.The upper limit for the fault current, which when open Flap flows is determined by the dangerousness limit, according to IEC Report 479 at about 12 mA at 50 Hz lies. It serves to increase security when the Fault current not equal to this limit value, but at for example, is only half of this value.

Dies kann auf verschiedene Weise erreicht werden. Beson­ ders einfach läßt sich dieser Wert erzielen, wenn der Wi­ derstand einen Wert von ca. 40 kΩ besitzt.This can be accomplished in a number of ways. Especially This value can be easily achieved if the Wi which has a value of approx. 40 kΩ.

Die Erfindung ist anhand der Zeichnung weiter erläutert. In der einzigen Figur ist ein Ausführungsbeispiel für die erfindungsgemäße Ladestation dargestellt.The invention is further illustrated by the drawing. In the single figure is an embodiment for the shown charging station according to the invention.

Die in Ausschnitten gezeigte Ladestation besitzt eine Spannungsquelle von 230 V Wechselspannung, an der eine Steckdose 3 angeschlossen ist. In der Verbindung des spannungsführenden Pols 3′ befindet sich ein Schalter 4, der mit der Bewegung einer nicht dargestellten Klappe ge­ koppelt ist. Die Klappe deckt die Steckdose 3 ab bzw. er­ möglicht nach Öffnen den Zugang zur Steckdose 3. Der Schalter 4 ist geöffnet, wenn die Klappe geöffnet ist und geschlossen, wenn die Klappe geschlossen ist. Damit liegt nur bei geschlossener Klappe die Versorgungsspannung der Spannungsquelle 2 an der Steckdose 3 an.The charging station shown in sections has a voltage source of 230 V AC, to which a socket 3 is connected. In the connection of the voltage-carrying pole 3 'there is a switch 4 which is coupled to the movement of a flap, not shown. The flap covers socket 3 or, after opening, allows access to socket 3 . The switch 4 is open when the flap is open and closed when the flap is closed. The supply voltage of voltage source 2 is thus only present at socket 3 when the flap is closed.

Die Steckdose wirkt mit einem Fehlerstrom-(Schutz)- Stecker 5 zusammen, der über eine dreiadrige Leitung 6 mit einem Bordladegerät eines Elektrofahrzeugs (beides nicht dargestellt) verbunden ist. Der Stecker 5 ist mit den Kontaktstiften 7, 8 in die Steckdose 3 einsteckbar.The socket interacts with a fault current (protection) plug 5 , which is connected via a three-wire line 6 to an on-board charger of an electric vehicle (neither of which is shown). The plug 5 can be inserted into the socket 3 with the contact pins 7 , 8 .

Der Fehlerstromstecker 5 besitzt ferner eine manuell be­ dienbare Einschalttaste 9, mit deren Hilfe die Kontakte 10 bis 12 schließbar sind, und die nur dann einrastet, wenn mindestens ein genügender Haltestrom von einigen mA fließt. Bedingt durch die beschriebene Wirkungsweise des Schalters 4 ist dies jedoch nicht möglich, solange die Klappe der Ladestation 1 geöffnet ist.The fault current connector 5 also has a manually operated switch 9 , with the help of which the contacts 10 to 12 can be closed, and which only engages when at least a sufficient holding current of a few mA flows. Due to the described mode of operation of the switch 4 , however, this is not possible as long as the flap of the charging station 1 is open.

Erfindungsgemäß ist der Schalter 4 mit einem Widerstand 13 überbrückt, der einen Wert von beispielsweise 40 kΩ bei einer Leistung von 1,5 W besitzt. Damit fließt bei geöffnetem Schalter 4 über den Widerstand 13 ein Haltestrom von ca. 5 mA. Dieser Strom reicht aus, um mit Hilfe der Einschalttaste 9 die Kontakte 10 bis 12 zu schließen.According to the invention, the switch 4 is bridged with a resistor 13 , which has a value of, for example, 40 kΩ with a power of 1.5 W. With the switch 4 open, a holding current of approximately 5 mA flows through the resistor 13 . This current is sufficient to close the contacts 10 to 12 using the ON button 9 .

Damit ist es möglich, bei geöffneter Klappe den Fehler­ stromschalter 5 manuell mit dem Bordladegerät zu verbin­ den. Nach Schließen der Klappe der Ladestation 1 liegt bei dann wieder geschlossenem Schalter 4 die volle Lade­ spannung an der Steckdose 3 an. Das Bordladegerät wird dann über den zuvor manuell mit Hilfe der Taste 9 ge­ schlossenen Fehlerstromstecker 5 mit der Ladespannung versehen und damit wiederaufgeladen. Damit ist es mög­ lich, bei weiterhin bestehenden Sicherheitsmaßnahmen in Form des mit der Bewegung der Klappe gekoppelten Schal­ ters 4 und des manuell bedienbaren Fehlerstromstecker 5 das Elektrofahrzeug wiederaufzuladen.This makes it possible to manually connect the fault current switch 5 to the on-board charger when the flap is open. After closing the flap of the charging station 1 , when the switch 4 is closed again, the full charging voltage is present at the socket 3 . The on-board charger is then provided with the charging voltage via the ge previously closed fault current plug 5 using the button 9 and thus recharged. This makes it possible to recharge the electric vehicle if security measures still exist in the form of the switch 4 coupled with the movement of the flap and the manually operated fault current plug 5 .
