Embodiment Construction

[0030] figure 1 A motor vehicle body-in-white of a passenger car is shown in a perspective exploded view with an underbody assembly 1 and an energy store 2 , which is partially formed by the underbody assembly 1 and by the base plate 19 . With the aid of the energy storage device 2 , electric energy can be provided for the drive of a motor vehicle, for example, which is fully electric or driven by a hybrid drive.

[0031]The underbody assembly 1 is mainly formed by a vehicle floor 3 , which is here substantially planar, in particular by one or more sheet-metal profiled elements. This vehicle floor 3 is laterally delimited by respective side sills 4, 5 extending substantially horizontally in the vehicle transverse direction between respective front wheel wells 6 and rear wheel wells 7 on each side of the vehicle. In the front area, the underbody assembly 1 is delimited forward by a front cross member 8 which - with respect to the longitudinal direction of the vehicle - extends...

Abstract

The invention relates to a stored energy source (2) for a motor vehicle, comprising a bottom plate (19), by means of which battery modules (16) in question are at least indirectly supported and by means of which the stored energy source (2) is delimited at the bottom. In order to provide a stored energy source (2) that is optimized with respect to its behavior during an accident and with respect to the vehicle package and does not require any installation space in the interior of the motor vehicle, the stored energy source (2) comprises at least one line (27), which runs above the bottom plate (19) and exits the stored energy source (2) at a front and a rear end (28, 29).

Description

technical field [0001] The invention relates to an energy storage device for a motor vehicle according to the preamble of claim 1 . Background technique [0002] From EP 2 468 609 A2 such an energy accumulator is known which is inserted into an underbody assembly, in which the vehicle floor of the underbody assembly is laterally bounded by corresponding side sills and reinforced by side members and / or cross members. In this case, the energy store has a housing in which the corresponding cells or battery modules are accommodated. The housing is reinforced by the frame-like structure of the profile elements surrounding the outer circumference and the cross members, so that the energy store can be fastened to the underside of the vehicle floor by corresponding screw connections, in particular in the region of the side sills. In order to achieve the best possible force transmission between the energy store and the underbody assembly, the energy store is adapted in its size and ...
