Abstract

A method is provided for carrying out a charging process of a vehicle-external charging apparatus ( 1 ) for charging a vehicle ( 2 ), in particular an electric or hybrid vehicle. The method includes using a current measuring instrument ( 3 ) of the charging apparatus ( 1 ) to measure a charging current. The method then includes closing a first contactor ( 4 ) of the charging apparatus ( 1 ) and a second contactor ( 5 ) of the vehicle ( 2 ) for a time period that is measured by the current measuring instrument ( 3 ). A charging apparatus ( 1 ) for performing the method also is provided.

First claim

What is claimed is:

1 . A method for carrying out a charging process of a vehicle-external charging apparatus for charging a vehicle, the method comprising measuring a charging current by a current measuring instrument of the charging apparatus and the current measuring instrument for measuring a time period in which a first contactor of the charging apparatus and a second contactor of the vehicle are closed.

2 . The method of claim 1 , the measuring of the time period is carried out by an evaluation device of the current measuring instrument.

3 . The method of claim 2 , wherein a price for the charging process is determined the measured charging current and the measured time period.

4 . The method of claim 3 , wherein the evaluation device has a display device, and the method comprises separately displaying on the display device respective amounts for charging and for parking.

5 . The method of claim 1 , wherein measuring the time period comprises transmitting information about whether the first contactor is open or closed from a first positively driven auxiliary contact of the first contactor via a first sensor line to the evaluation device of the current measuring instrument, and transmitting information about whether the second contactor is open or closed from a second positively driven auxiliary contact of the second contactor via a second sensor line to the evaluation device of the current measuring instrument.

6 . The method of claim 1 , further comprising measuring an electrical voltage between the vehicle and the charging station.

7 . The method of claim 6 , wherein the measuring an electrical voltage between the vehicle and the charging station comprises measuring the electrical voltage between the first contactor and the second contactor.

8 . The method of claim 7 , further comprising measuring a time period in which the electrical voltage is not equal to zero volts and comparing the time period in which the electrical voltage is not equal to zero volts to the time period in which a first contactor of the charging apparatus and a second contactor of the vehicle are closed.

9 . The method of claim 7 , wherein information about whether the second contactor is open or closed is determined by measuring electrical voltage with the first contactor open.

10 . The method of claim 1 , further comprising terminating the charging process after exceeding of a maximum time duration before the first and second contactors are closed.

11 . A charging apparatus for charging a vehicle, the charging apparatus comprising a current measuring instrument for measuring a charging current and measuring a time period in which a first contactor of the charging apparatus and a second contactor of the vehicle are closed.

12 . The charging apparatus of claim 11 , wherein the current measuring instrument comprises an evaluation device for measuring the time period.

13 . The charging apparatus of claim 12 , wherein the evaluation device has a display device that separately displays respective amounts for charging and for parking.

14 . The charging apparatus of claim 12 , further comprising a voltmeter for measuring an electrical voltage between the vehicle and the charging station.

15 . The charging apparatus of claim 12 , wherein the evaluation device and the current measuring instrument are arranged in a common housing.
