Embodiment Construction

[0028] figure 1 and 2A motor vehicle body 1 for an electrically operable motor vehicle is shown in a perspective exploded view and a perspective bottom view, respectively. The motor vehicle can be, for example, such a motor vehicle with a fully electric drive (BEV) or a hybrid vehicle (PHEV) which, in addition to a purely electric drive, also has an internal combustion engine. In the present case, the motor vehicle body 1 generally comprises a front end wall 2 of the passenger compartment, which adjoins forwardly a front structure 3 , which includes, for example, a corresponding longitudinal member / engine mount 4 of the central longitudinal member plane. The end wall 2 transitions rearwardly into a transition region 5 , which for example includes an obliquely extending pedal base or the like and transitions into a vehicle floor 6 , which delimits the passenger compartment downwards and extends to—on the outside in the longitudinal direction of the vehicle direction and exten...

Abstract

The invention relates to an energy storage floor assembly for a motor vehicle, comprising an electrical energy storage device (19) comprising a plurality of battery modules (18), which is accommodated in a multi-part storage housing (17) and is arranged on the underside of a vehicle floor (6) of the motor vehicle. In order to enable the accumulator housing (17) to be adapted in an improved manner to the shape of a motor vehicle body (1) and / or to parts of an energy storage device (19), the respective housing parts (6, 16) of the accumulator housing (17) are connected to each other by means of at least one gas-tight connection (13), the gas-tight connection has a non-planar extension in at least one length region (Lh, Lv) with respect to the vertical direction (z-direction) of the vehicle.

Description

technical field [0001] The invention relates to an accumulator base assembly for a motor vehicle according to the preamble of claim 1 . Background technique [0002] Such an accumulator underbody assembly is known from EP 2 468 609 A2, in which the vehicle underbody of the underbody assembly is delimited laterally by corresponding side sills and reinforced by side members and / or cross members. A plurality of battery modules of an electrical energy storage device for supplying electrical energy to an electric drive of a motor vehicle are accommodated in an accumulator housing having an upper shell and a lower shell. The two shells are connected to one another by a flange connection which extends circumferentially in one plane. In the area of ​​this flange connection, the accumulator housing is fastened to the underside of the vehicle underbody by corresponding screw connections in the area of ​​the side sills and cross member. The accumulator housing is therefore designed a...
