Charging Device for an Electric Vehicle

摘要

The invention relates to a charging device for an electric vehicle that can be driven by an electrical energy store. The charging device has a charging interface outside the electric vehicle, which can be fed by a three-phase alternating current from an external three-phase alternating current network. The charging device provides a charging current at the output that can be fed via a charging cable to the electric vehicle in order to charge the electrical energy store. The charging interface comprises a converter device configured to convert the three-phase alternating current into a single-phase alternating current as the charging current, and to distribute 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.

1. A charging device for an electric vehicle configured to be driven via an electrical energy store comprises:
a charging interface outside of the electric vehicle configured to be fed at an input by a three-phase alternating current from an external three-phase AC grid, configured to provide a charging current at an output, wherein the charging current is supplied to the electrical energy store of the electric vehicle via a charging cable, wherein the charging interface comprises a converter device for converting the three-phase alternating current into a single-phase alternating current as the charging current, which converter device, during operation, distributes a phase load on the line phase of the single-phase alternating current substantially uniformly among the three line phases of the three-phase alternating current.
