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.

A tank system (1) for a motor vehicle having an internal combustion engine to which fuel is supplied from a tank (2), wherein the tank (2) is assigned, in a ventilation path to the atmosphere (7), a flushable filter device (6, 6) for being loaded with hydrocarbon vapors of the fuel. The filter device (6, 6) has multiple mutually separate activated carbon filters (6). All of the activated carbon filters (6) are connected permanently in parallel. In this way, the ventilation resistance from the tank in the direction of the atmosphere can be kept low.


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.

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).


A circuit system for a charging station which is configured to charge an energy store in a vehicle, the circuit system including a transformer with transformer outputs which are DC-isolated from one another, a first subsystem and a second subsystem each being connected to one of the transformer outputs. The first subsystem and the second subsystem each include a rectifier which has a DC-DC converter connected upstream of it, the DC-DC converter being coupled to a changeover logic unit on its input side or on its output side. In particular, provision is made for the first subsystem to be connected to a delta circuit in the transformer output and for the second subsystem to be connected to a star circuit in the transformer output.


A method for controlling an automatic transmission of a vehicle includes detecting a deceleration of the vehicle; detecting a cornering value of the vehicle; determining, as a function of the deceleration and as a function of the cornering value, a compensated shift-down point of a rotational speed at which shifting into a relatively low gear of the transmission occurs; and selecting a gear as a function of the compensated shift-down point.
