A method for charging a high-voltage battery of an electric vehicle, comprising: providing the high-voltage battery having a nominal battery voltage; providing a charging station outputting a DC charging voltage less than the nominal battery voltage; draining current between a first battery terminal and a protective earth terminal such that the voltage between the first battery terminal and the protective earth terminal essentially matches with the voltage between a first charging terminal and the protective earth terminal, and boosting the voltage at a second charging terminal of the charging station to match the charging voltage with the nominal battery voltage.
