Embodiment Construction

[0029] exist figure 1 and 2A motor vehicle body 1 for an electrically runable motor vehicle is shown in a perspective exploded view or a perspective bottom view. The motor vehicle can be, for example, such a motor vehicle (BEV) with an all-electric drive or a hybrid vehicle (PHEV) which, in addition to a purely electric drive, also has an internal combustion engine. The motor vehicle body 1 in the present case comprises, in the usual manner, a front end wall 2 of the passenger compartment, to which a front body front structure 3 is connected, which comprises, for example, a central longitudinal Corresponding longitudinal beams / engine mounts 4 of the beam plane. The end wall 2 merges rearward into a transition region 5 (which includes, for example, an obliquely extending footrest or the like) and into the vehicle floor 6 , which delimits the passenger compartment downwards and extends until—at The outer side extending horizontally in the longitudinal direction of the vehicle...

Abstract

The invention relates to an energy storage base assembly for a motor vehicle, comprising an electrical energy storage device (20) 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 base (6) of the motor vehicle. In order to provide an energy storage floor assembly for a motor vehicle, in which an energy storage device (20) is connected in an improved manner to a body-in-white (1) of the motor vehicle, a battery module (18) of the energy storage device (20) is connected to the vehicle floor (6) in a middle region of an energy storage housing (17) via a plurality of mechanical connecting elements (31).

Description

technical field [0001] The invention relates to an accumulator underbody assembly for a motor vehicle according to the preamble of claim 1 . Background technique [0002] Such an accumulator underbody arrangement is already known from EP 2468609 A2, wherein the vehicle underbody of the underbody arrangement 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 here in a multi-part accumulator housing. The accumulator housing here has a frame-like structure of profile elements running around on the outer circumference and a plurality of cross members, so that the accumulator housing itself is of rigid design and is connected via corresponding threads in the region of the side sills and the cross members fixed on the underside of the vehicle bottom. The high inertial fo...
