Abstract

Various embodiments of the teachings herein include a charging circuit for a vehicle-side electrical energy store comprising: an alternating current terminal; at least two smoothing capacitors; a configuration device; and a rectifier connecting the alternating current terminal to the configuration device. The configuration device connects the rectifier to the smoothing capacitors, and the configuration device is programmed to connect the smoothing capacitors to one another in a first parallel connection and a second series connection. The alternating current terminal comprises a neutral conductor terminal connected to the configuration device via a diode circuit. The configuration device comprises a first switch connecting the smoothing capacitors to one another in parallel when closed. The configuration device comprises a diode connecting the smoothing capacitors to one another in series when closed.
