A rear-end diffuser arrangement for a motor vehicle has at least one flap (16, 18; 32) mounted on a body part (10) of the motor vehicle (2) so as to be movable by at least one drive device (38). The flap (16, 18; 32) is movable from a retracted state into a deployed state and vice versa. The at least one flap (16, 18; 32) has a concavely curved surface facing toward the vehicle rear end (20).


A vehicle has a charging device for charging an energy store at a charging station. The charging device has a vehicle-side coupling element for coupling to a charging-station-side coupling element. A control unit is provided is arranged in the region of the vehicle-side coupling element for maneuvering the vehicle.

An electric line arrangement, in particular a charging cable for a motor vehicle, having at least one electrically conductive lead which can be placed in electrical contact at its ends in order to transmit electrical energy, an insulation layer which surrounds the lead circumferentially, and a coolant duct in which a cooling fluid for cooling the lead is conducted, wherein the insulation layer is spaced apart from the lead, and the coolant duct is formed between the insulation layer and the lead in such a way that the cooling fluid flows directly around the lead.


A hybrid vehicle (1) has an internal combustion engine (2), an electric machine (3) and a transmission (4) for driving a rear axle (5) of the vehicle (1). The internal combustion engine (2) and the electric machine (3) are assigned a common input shaft (6) of the transmission (4). The internal combustion engine (2), the electric machine (3) and a traction battery (19) for the electric machine (3) or a tank for the internal combustion engine (2) are arranged in a rear region of the vehicle (1), transversely with respect to the direction of travel. The electric machine power is greater than the power of the internal combustion engine (2). A high level of electrification of the hybrid drive is possible with optimum utilization of space in the vehicle.


Prior art electronic power supplies having distributed energy stores and/or the possibility to dynamically modify the connectivity of individual stores require complex monitoring of the input and output currents to and from the individual energy stores, often using a multitude of sensors, in order to allow for unrestricted operation. Examples of such power supplies include in particular modular multilevel converters and switched-capacitor circuits. The present invention describes a possibility to determine the states of charge and energy levels of the energy stores using a small number of measuring systems.


Patent
Porsche | Date: 2017-02-15

The present invention relates to an apparatus for electrical power supplies and electrical storage systems. While conventional storage systems, for example batteries, offer very limited electrical properties, for example DC voltage with a voltage which is prespecified by the battery design and the state of charge, the invention can deliver virtually any desired current and voltage profiles within certain limits, for example a maximum voltage and a maximum current, without the need for a separate power-electronics converter circuit. At the same time, the invention can not only output but also receive energy in virtually any desired form and charge its integrated electrical energy stores, for example capacitors, batteries, rechargeable batteries and the like, while maintaining prespecified charging properties, for example specific current and voltage profiles or power output profiles over time (for example constant, increasing with a specific profile or falling with a specific profile).
