Abstract
A method (400) for operating an electrically driven vehicle (300), comprising the following steps: emitting a signal for controlling (420) a connectable charging means (160) for charging an intermediate circuit capacitor (140); determining (440) a voltage at an intermediate circuit capacitor (140) or of the charge thereof; emitting a signal for closing (460) the switches (130) for connecting the traction battery (150) to the high-voltage grid (110) as a function of the determined voltage or charge.
