Title:
CHARGING DEVICE FOR AN ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2014/140004
Kind Code:
A3
Abstract:
The invention relates to a charging device for an electric vehicle (1) that can be driven by means of an electrical energy store (2), the charging device comprising a charging interface (5) outside the electric vehicle (1), which charging interface can be fed at the input by a three-phase alternating current from an external three-phase alternating current network and provides a charging current at the output that can be fed via a charging cable (4) to the electric vehicle (1) in order to charge the electrical energy store (2). The charging device according to the invention is characterised in that the charging interface (5) comprises a converter device (6) for converting the three-phase alternating current into a single-phase alternating current as the charging current, which converter device distributes a phase load on the conduction phase of the single-phase alternating current substantially uniformly onto the three conduction phases of the three-phase alternating current during operation.
