A vehicle having an electric drive device and an energy storage device which is arranged in a housing is disclosed. The energy storage device is formed from a plurality of cells. The housing includes a plurality of partitioning devices, with the result that at least one partitioning device is positioned between two cells. The housing of the energy storage device is connected both to a cooling air intake duct, having an inlet opening, and to a cooling air outflow duct, having an outlet opening. At least one partitioning device is configured in such a way that a plurality of cooling ducts are formed between the cells, and cooling air can flow through the cooling ducts in order to cool the energy storage device.

Vehicle having an electric drive device

A drive arrangement for an electric vehicle has an axle drive device of a portal design with two electric machines for driving the wheels of an axle of the electric vehicle, and at least one electric energy store that can be discharged when an electric machine is operated as a motor and/or can be charged when an electric machine is operated as a generator. The drive arranged is characterized in that the two electric machines () of the axle drive device () are combined with a respectively assigned transmission () in an electric axle to drive the individually suspended wheels () of the axle by means of, in each case, one articulated shaft flange () via a respective articulated shaft. Frequency converters assigned respectively to the two electric machines are combined in a converter unit.

Drive arrangement for an electric vehicle

Inlet openings at the frontal region of a vehicle have actuable transversely oriented pivoting lamellae disposed behind them. The lamellae guide an air flow to a vehicle radiator in a targeted manner. The pivoting lamellae are connected to an actuating device with control linkages that are articulated to one another via deflection levers for an upper and a lower lamella unit. The upper pivoting lamellae are adjusted at an angle which is different than the lower pivoting lamellae. The upper pivoting lamellae can be set in each case as a unit jointly with the lower pivoting lamellae as a further unit.
