597990 A method of controlling a charging apparatus connected to an AC voltage network for charging and/or discharging of electric storage devices of electric vehicles and a charging apparatus (1) for charging electric storage devices (28) of electric vehicles are disclosed. The charging apparatus includes: a feed-in unit (2) for feeding electric energy into an electric AC voltage network (14) and at least one accumulator unit (4) and/or at least one charging connection. The feed-in unit (2) including an electric DC voltage intermediate circuit (6) for the intermediate storage of electric energy with an intermediate circuit voltage, and an inverter (8) which is provided for converting a direct current and/or a DC voltage of the DC voltage intermediate circuit (6) into an alternating current, for feeding it into the electric AC voltage network (14) and for converting an alternating current from the AC voltage network (14) into a direct current and/or into a DC voltage for feeding it into the DC voltage intermediate circuit (6)> The at least one accumulator unit (4) and/or at least one charging connection is for the connection of an accumulator unit (4) for at least partial charging of one of the electric storage devices (28) from the DC voltage intermediate circuit (6) and/or for at least partial discharging of one of the electric storage devices (28) into the DC voltage intermediate circuit (6). The feed-in unit is provided to feed reactive power into the electric ac voltage network and/or wherein a feed-in unit of a wind power installation is used as the feed-in unit. Also disclosed is a wind power installation for converting wind power into electric energy including the above described charging apparatus and/or components of the above described charging apparatus. An electric filling station includes the above described wind power installation and/or the above described charging apparatus and at least one electric storage device connected to the charging apparatus. A preferred electric storage device is provided to be exchanged in the charged condition for an entirely or partially discharged electric storage device of an electric vehicle. |
