CHARGING SYSTEM AND METHOD FOR CHARGING A BATTERY OF AN ELECTRIC VEHICLE

A charging system for charging an electric vehicle battery, including a charging inlet connected to an external direct current (DC) charging station providing a predefined charging inlet voltage, a battery having a nominal voltage of 400V or 800V connected to the charging inlet, the battery including two 400V-battery units, and a voltage outlet, the voltage outlet supplying an output voltage to an auxiliary component connected to the voltage outlet having a nominal voltage corresponding to the nominal voltage of the battery, a DC/DC converter converting the charging inlet voltage into the nominal voltage of the auxiliary component, and at least three circuit breakers being arranged to connect the two 400V-battery units to form a charging circuit having a nominal charging voltage corresponding to the supplied charging inlet voltage and/or to selectively integrate the DC/DC converter into the charging circuit to provide the auxiliary component with the nominal voltage during charging.
