An electric energy storage device () for a motor vehicle, in particular a high-voltage energy storage device for a hybrid vehicle or an electric vehicle, having a housing () and having storage modules () accommodated in the housing. The housing () has a housing top part (), a housing bottom part () and a supporting element () with an annular supporting frame (). The housing bottom part () and the housing top part () are connected detachably to the supporting frame (), which is positioned between them. The annular supporting frame () has fastening sections () for detachably connecting the electric energy storage device to a body structure of a motor vehicle.

Electric energy storage device for a motor vehicle

An electric energy store () of a motor vehicle, in particular a high voltage energy store of a hybrid vehicle or an electric vehicle, has a housing () and storage modules () accommodated in the housing. The housing () has a supporting element () with an annular supporting frame () made from a fiber reinforced plastic and via which the electric energy store () can be connected to a body structure of a motor vehicle.

Electric energy store of a motor vehicle

A motor vehicle has a body () having a plurality of bearings (). The bearings () are disposed and configured for mounting a supporting structure () that houses an electric drive unit () that includes an electric drive motor () and a high-voltage battery () for providing electric energy. The bearings () also are disposed and configured for mounting an internal combustion engine () and a transmission () connected to the internal combustion engine (). Thus, the motor vehicle does not have to be redesigned depending on whether the motor vehicle is powered by an electric drive unit () or an internal combustion engine ().

Motor vehicle with an electric drive unit

An electrical energy store of a motor vehicle, in particular a high voltage energy store of a hybrid vehicle or of an electric vehicle, having a housing () and having storage modules () accommodated in the housing (). The housing () having a supporting element () connecting the electrical energy store to a vehicle bodywork structure of a motor vehicle. The temperature of the storage modules () can be controlled via the supporting element ().

Electrical energy store of a motor vehicle

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

A motor vehicle has an electrical drive machine that is supplied with electrical energy by an electrical energy storage device, and has an underbody region or surface (). The electrical energy storage device is accessible for maintenance and/or installation work via a maintenance cover () in the underbody surface () to reduce time required for maintenance and/or installation work.

Motor vehicle

A contact-making apparatus is provided for producing a low-voltage connection between a motor vehicle () and a charging apparatus. The contact-making apparatus has at least one motor vehicle contact element () associated with the motor vehicle, and with at least one charging contact element () associated with the charging apparatus. To simplify the production of a low-voltage connection between a motor vehicle and a charging apparatus, the charging contact element () has a charging contact face () that can fit on the charging apparatus movably relative to a motor vehicle contact face and has a configuration matched to the configuration of the motor vehicle contact face on the motor vehicle contact element ().

Contact-making apparatus having a charging contact element rotatable by a drive motor

A cockpit support structure of a motor vehicle has a cross member () with brackets () for connecting the cross member () to a body structure of the motor vehicle, and having brackets () for connecting functional components to the cross member (). The cross member () and the brackets () all are produced from a magnesium alloy material.

Cockpit support structure of a motor vehicle

An inner and an outer spring plate are disposed, in a radially spaced relationship from one another, on a spring strut cylinder. In a first springing position (normal position), the helical spring is supported with a turn region of small diameter against the inner spring plate. In a second springing position (sports position) of the helical spring, the latter is supported with a turn region of larger diameter against the outer spring plate.
