Abstract: A charging device for a high-voltage battery of a motor vehicle, in particular a charging device installed in a motor vehicle, can be connected to an alternating current network via a connection device, which includes a residual current circuit breaker that does not detect a residual current of at least one residual current type, in particular a DC residual current. The charging device further includes a controllable component and a residual current detector for detecting a residual current of the residual current type, wherein the residual current detector controls the component to change the characteristic of the residual current in such a way that the residual current can be detected with the residual current circuit breaker.

Abstract: A charging device installed in a motor vehicle is connected via a connection device to an AC mains. The connection device includes a residual current circuit breaker incapable of detecting at least one residual current type, in particular a DC residual current. A communication signal is transmitted between a control unit on the side of the charging device and a control unit on the side of the connection device. A residual current detector in the charging device detects a residual current of the undetected residual current type and transmits a residual current signal indicating the residual current to the charging-device-side control unit, which then modifies and/or interrupts the communication signal based the residual current signal so as to cause the charging device to be disconnected from the AC mains.
