Abstract
A method provides a supply current (303) for high-voltage consumers (114), in which a battery-electric vehicle has a charging power unit with a high-voltage intermediate circuit (110) for charging a high-voltage battery (102). The high-voltage intermediate circuit (110) includes a high-capacitance charging device (106), at least one bi-directional power output stage (112a, 112b) having a connection to the high-voltage battery (102), and at least one high-voltage consumer (114). The high-voltage intermediate circuit (110) has a high intermediate circuit capacitance at least through the charging device (106). The bi-directional power output stage (112, 112b) is actuated with a pulse width modulation, and, through the at least one bi-directional power output stage (112a, 112b), a supply current (303) is provided from the high-voltage battery (102) to the high-voltage consumer (114) via the high-voltage intermediate circuit (110). The supply current (303) is smoothed due to the high intermediate circuit capacitance.
