Abstract
A method is provided for operating a bidirectional charger (1) for DC charging of electric vehicles. The charger (10) has a charging terminal (11) for connecting an electrically driven vehicle and at least one power electronics unit (12) for providing defined charging current and defined charging voltage at the charging terminal (11). The power electronics unit (12) is subjected to a self-test voltage of at least the maximum charging voltage of the charger (10) at defined time intervals for a defined time for performing a self-test when there is no vehicle at the charging terminal (11). A check then is performed to ascertain whether a short circuit or defect is formed at the power electronics unit (12). The charging terminal (11) is enabled for charging a vehicle if no short circuit is found and the charging terminal is blocked for charging a vehicle when a short circuit is established.
