A motor vehicle with two front wheels and two rear wheels and with an electric drive that is operable via a traction energy storage device. The motor vehicle has a front recess in the region between the front wheels for a traction energy storage device assigned to the front recess, and has a rear recess in the region between the front wheels and the rear wheels, arranged in an underbody of the motor vehicle, for a traction energy storage device assigned to the rear recess, and traction energy storage devices are insertable or inserted into the recesses.

Motor vehicle and method for arranging at least one traction energy storage device in a motor vehicle

The invention relates to a receiving device for receiving at least one energy storing component, includes at least one receiving part which delimits at least some sections of a receiving chamber for receiving the energy storing component. A coolant channel structure which includes at least one coolant channel is formed in at least some sections of the surface of the receiving part, wherein the coolant channel structure communicates with at least one coolant inlet and at least one coolant outlet.

Receiving device for receiving at least one energy storage component

A motor vehicle with an energy storage device with at least one electric energy store and an air conditioning device for an active control of the temperature of the energy store accommodated in a housing. At least one air inlet opening and at least one air outlet opening are provided at the housing, and an ambient air stream can be guided by the air inlet opening into the housing and by the air outlet opening from the housing for passive cooling.

Motor vehicle and energy storage device

A vehicle having electrical storage devices with at least one of several electrical energy storage cells for supplying electrical energy to at least one vehicle-side consumer of electrical energy. At least one receiving device that is or can be arranged in the subfloor of the vehicle for accommodation of electrical energy storage cells, which include at least two separate receiving parts for accommodation of electrical energy storage cells. At least two receiving parts are connected to at least one connecting bar extended between them, wherein in and/or on the at least one connecting bar at least one line connection is formed for electrical connection of the energy storage cells accommodated in the respective receiving parts and/or at least one line connection for guiding a temperature-control fluid to control temperature in the energy storage cells accommodated in the respective receiving parts.

Motor vehicle and receiving device for receiving electrical energy storage cells

The invention relates to a vehicle having, at least in part, an electric drive which includes a traction battery (), which vehicle has at least one predefined deformation zone (I, II) which in the event of a crash (A, B) acts to absorb energy, and at least one predefined zone (III), which has a substantial structural rigidity and which in the event of a crash (A, B) remains substantially without deformation. According to the invention, the traction battery () has a deformation region () which in the event of a crash can be deformed via a deformation path (a) and which is arranged in the deformation zone (I, II) of the vehicle.

Vehicle with traction battery capable of absorbing crash energy

A channel of a motor vehicle with a reinforcing insert. The channel serves as an essential load bearing structure of a motor vehicle. The channel is also served as a stable barrier to protect the passenger compartment in the event of a crash.

Channel with reinforcing insert of a motor vehicle

The invention concerns a stress-bearing structure of a motor-vehicle body made with hollow section beams, having at least at one structural member junction point (1) at which a first hollow section beam (2) is joined with a second hollow section beam (3) and a third hollow section beam (4), which are opposite each other on either side of the first hollow section beam. The second and third hollow section beams (3, 4) are attached to the respective opposite sides of the first hollow section beam (2) by a butt joint. The junction point (1) is reinforced by a junction point reinforcement element in the form of a hollow section extrusion (6). In accordance with the invention, a hollow section extrusion (6) is positioned beneath the structural-member junction point (1) on the inside of the vehicle body and fixed in place. The longitudinal axis of the hollow section extrusion (6) runs in the same direction as the longitudinal axis of the first hollow section beam (2). The transverse profile of the extrusion section has a greater width than the width of the first hollow-section beam (2), so that the extrusion section lies against both the second hollow-section beam (3) and the third hollow-section beam (4) with its contact surfaces (11, 13) attached to them. Lateral stresses exerted on the structural-member junction point (1) are absorbed and stayed by the hollow section extrusion (6) which functions as a tie rod. In a preferred embodiment of the invention, the hollow section beams (2, 3, 4) and the section of extrusion (6) are made of a light metal.
