Abstract
A charging device for securing a charging process of a high-voltage battery of a motor vehicle, which may be provided with a first connecting device for coupling a charging cable of a charging station external to a vehicle and a second connecting device for connecting the high-voltage battery. A diode element may be provided between the first connecting device and the second connecting device, which may be adapted to independently allow a charging current to flow from the charging stations into the battery and prevent a discharge current from flowing from the high-voltage battery to the charging station. The charging device may further include a monitoring device configured to detect a predetermined feedback situation, in which the diode element blocks the discharge current or prevents the discharge current from flowing through the diode element during a defect. When a feedback situation is detected, a predetermined emergency shutoff measure is taken.
