Embodiment Construction

[0047] figure 1 Shows a schematic sectional view of a conventional attachment device of an electrical energy source EQ for providing traction to an electric vehicle (ie driving the electric vehicle) in a mounted state in a section perpendicular to the straight direction GF of the electric vehicle.

[0048] The electrical energy source EQ can be designed, for example, as a rechargeable battery (“high-power battery”, “traction battery”), for example as a lithium-ion battery. The electrical energy source EQ is housed and fixed in a housing G which is arranged under the vehicle floor FB between the door sills S of the electric vehicle. Due to the stringent requirements for electrical energy storage density, the electrical energy source EQ does not have any externally accessible internal support structures or through-holes through which attachment elements such as screw elements or drawbars pass, so that the electrical energy source EQ can only be passed through external connection...

Abstract

The invention relates to an attachment device (10) for an electrical energy source (38) for providing traction for a vehicle, preferably for an electric vehicle which can be arranged below a vehicle floor (48) between thresholds (40, 42) of the vehicle. The attachment device (10) has a housing (12) for accommodating and securing an electrical energy source (38) and a plurality of attachment elements (24, 26) for attaching the housing (12) to a body of a vehicle, in particular an electric vehicle. According to the invention, a plurality of attachment elements (24, 26) have a housing side end (28) attached to the housing (12) and a sill side end (32) attached to one of the sills (40, 42). In this case, the attachment element (24, 26), in the mounted state, has an at least partially curved contour with at least one inflection point (36) between the housing side end (28) and the sill side end (32) in at least one virtual plane arranged perpendicularly to the straight direction (50) of the vehicle.

Description

technical field [0001] The invention relates to an attachment device according to the preamble of claim 1 for an electrical energy source for providing traction, ie propelling, a vehicle, preferably an electric vehicle. Background technique [0002] The known field of motor vehicle engineering includes motor vehicles whose main drive comprises an electric drivetrain with an electric motor which can be operated by means of an electric current generated by an electrical energy source such as an electrochemical energy store or an energy converter . The electrochemical energy store or energy converter can be formed here, for example, by at least one rechargeable battery (often also referred to somewhat imprecisely as a traction battery) or a fuel cell stack (“stack”). [0003] In a motor vehicle with a conventional internal combustion engine, the arrangement ("packaging") of the various components of the motor vehicle (drive, chassis, body) has matured over decades of developme...
