Abstract

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.

First claim

The invention claimed is:

1. A motor vehicle, comprising;
at least one of several electrical energy storage cells having an electrical storage device for supplying electrical energy to a vehicle-side electrical energy user; and
at least one receiving device that is arranged in the subfloor of the motor vehicle for accommodating electrical storage cells, which have at least two separate receiving parts for accommodation of electrical energy storage cells, wherein the at least the two receiving parts are connected via at least one connecting bar extending between them and set on respective bottom sides of the at least two receiving parts, wherein a line connection is formed within the at least one connecting bar to create a line connection for the electrical energy storage cells accommodated in respective receiving parts and at least one other line connection is formed within the at least one connecting bar for guiding a temperature-control fluid for controlling temperature of the energy storage cells accommodated in respective receiving parts,
at least one side rail structure is extending in the direction of the longitudinal axis of the motor vehicle, which is divided at least in sections into at least two side rails segments, wherein the side rail segments are extended in the state when the receiving device is arranged in the vehicle-side subfloor at least along the respective side surfaces respectively extending in the direction along the side surfaces of a receiving parts in the longitudinal direction of the motor vehicle,
wherein the at least one connecting bar is provided with a recess forming a through-opening running transversely to its longitudinal axis, wherein the recess creates a passageway for a vehicle-side structural component, at least one of a vehicle-side drive train or a structural component belonging to a vehicle-side exhaust system.

2. The motor vehicle according to claim 1 , wherein the at least one connecting bar is arched relative to its longitudinal axis to provide the passageway.

3. The motor vehicle according to claim 1 , wherein the at least one connecting bar is arranged on the vehicle-side subfloor with a bottom side proximate a road surface.

4. The motor vehicle according to claim 1 , wherein the at least one connecting bar is arranged on the vehicle-side subfloor with an upper side proximate the vehicle body.

5. The motor vehicle according to claim 1 , wherein at least one recess is formed in the subfloor of the motor vehicle for accommodation of one of the receiving parts.

6. The motor vehicle according to claim 5 , wherein the recess created in the subfloor of the vehicle is adapted in such a way that the accommodated one of the receiving parts is integrated flush with a bottom side in an underside of the motor vehicle.

7. The motor vehicle according to claim 1 , wherein the receiving device is or can be arranged in a region of the subfloor of the motor vehicle located below a front seat of the motor vehicle.

8. The motor vehicle according to claim 1 , wherein at least one receiving part is during the state when the receiving device is arranged in the vehicle-side subfloor with a flatter design in a front region relative to the longitudinal axis of the motor vehicle than in a rear region relative to the longitudinal axis of the motor vehicle.

9. The motor vehicle according to claim 1 , wherein the at least one connecting bar forms a part of a receiving frame for receiving at least one receiving part.
