A battery housing for an electric vehicle comprises a first housing part and a second housing part. The first housing part has a trough-type structure for receiving one or more battery modules. The second housing part is designed as a cover part for closing the first housing part. The housing parts have peripheral assembly flanges and are connected to one another on their assembly flanges by multiple fasteners extending through the assembly flanges. The assembly flange of at least one housing part carries multiple spacing elements arranged spaced apart from one another, each having a spacer arranged on the side of the assembly flange carrying the spacing element facing the assembly flange of the other housing part, wherein the spacer only covers a part of the total width of the assembly flange. A peripheral seal is located between and adhesively connected to the two assembly flanges. Here, the spacing elements each have at least one arm guided around the lateral edge of the assembly flange carrying the spacing element, and reaching to the opposite side, and supported on the opposite side of the assembly flange.

Battery housing for a vehicle operated by electric motor

A frame structure part for forming a frame structure for a battery housing of an electric motor vehicle with at least two hollow chamber profiles, which are connected to one another at an angle and each have at least two chambers and a mounting surface extending in the x-y plane and located on the upper side of the profiles in a common plane. A sealing fillet following the longitudinal extension of the profiles is introduced into the mounting surface for receiving a seal, wherein the ends of both profiles are mitered in a first profile section extending from the mounting surface over the entire extension of the uppermost chamber in the z-direction, and the miter joints are connected to one another, so that the joint-end mouths of the fillets of the two profiles adjoin one another. The first profile, in a second profile section located in the z-direction below the first profile section adjoining the same, bears with its end face against a side face of the second profile and is connected thereto. Also described is a battery housing with a frame structure having a plurality of such frame structure parts.

Frame structural part and battery housing with a frame structure composed of such frame structural parts

A battery case for a vehicle driven by an electric motor, said battery case comprising a tray part () which has a base () onto which side walls () having a mounting flange () are molded, and comprising a frame structure () which surrounds the tray part () on the outer side thereof and has a hollow chamber (). The side walls () of the tray part () are at the same time part of the frame structure () and separate the tray interior from the hollow chamber () of the frame structure (). The side walls () with their mounting flange () are part of the frame structure () and the frame structure () has at least two additional frame members () connected to the tray part () for completing the frame structure (), of which a first frame member () has a leg () which is opposite the side wall () of the tray part () and an upper terminating leg () for connection to the tray part (), and of which a second frame member is a closing plate () that connects the first frame member () to the tray part () on the undersides thereof.
