Abstract

A charging device for electrically charging and discharging a traction battery in an electric vehicle, comprises a first DC-DC converter; a vehicle plug; a power plug or network connection; a rectifier; a second DC-DC converter; a connection node; wherein the first DC-DC converter can be coupled with a DC power source and is coupled with the connection node; the rectifier can be coupled with the power plug and is coupled with the second DC-DC converter; and the connection node is coupled with the vehicle plug. The object of providing such a charging device with improved efficiency is achieved in that the connection node is connected between the second DC-DC converter and the vehicle plug.
