In a method for operating an electric vehicle, including an electrical drive device for driving the vehicle, a control device for controlling the driving of the vehicle, a first energy storage device for supplying the control device with a first DC voltage, a second energy storage device for supplying the drive device with a second DC voltage, and an energy supply unit providing an output DC voltage, the first energy storage device is connected to the energy supply unit via a converter device, the second energy storage device is connected to the energy supply unit, the converter device converts the output DC voltage into the first DC voltage, a first power flow from the first energy storage device to the second energy storage device is prevented and a second power flow from the second energy storage device to the first energy storage device is prevented.

Method for operating an electric vehicle and electric vehicle

A fan arrangement includes a fan and toothed ring, and a converter motor includes a fan arrangement. The fan includes a base body on which fan blades are premolded, and the fan includes an annular region, which is premolded on the side of the fan blades facing away from the base body. The toothed ring is situated within the annular region, and thus, in particular, is set apart from the base body, and thus, in particular, is set apart from the base body via the fan blades.
