Charging device for a high-voltage battery of a motor vehicle, charging system and method of operating a charging system

摘要

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.

1. A charging device for a high-voltage battery of a motor vehicle, comprising:
a connector configured receiving an external plug of a connection device for connecting the charging device to an alternating current network, wherein the connection device comprises a residual current circuit breaker incapable of detecting at least a DC residual current, a controllable component constructed as a power factor correction filter, and a residual current detection device configured to detect the DC residual current, wherein the residual current detection device controls the controllable component so as to deactivate the controllable component and change a characteristic of the residual current such that the residual current is detected by the residual current circuit breaker.
