Document Type and Number:
WIPO Patent Application WO/2010/149520
Kind Code:
A3
Abstract:
The invention relates to a method and a device for metering the electric energy supplied to an electric vehicle. For this purpose, the invention provides the following steps: connecting the electric vehicle (2) to a charging station (12) in order to obtain electric energy provided by a charging cable (10); supplying the requested quantity of energy to a battery (4) of the electric vehicle (2) during a requested charging time period; detecting at least one electric variable which is needed for calculating the quantity of energy by means of an energy quantity meter (16); and outputting the at least one electric variable which is needed by the energy quantity meter (16) to calculate the quantity of energy, said quantity being outputted to a monitoring device for monitoring the use of the charging station.
