A chassis platform module for an electric vehicle may include: a frame part having a battery mounted thereon; a first support part extended from one side of the frame part in a longitudinal direction, and having a front wheel chassis module mounted thereon; and a second support part extended from the other side of the frame part in the longitudinal direction, and having a rear wheel chassis module mounted thereon.

A battery enclosure, support beam for the battery enclosure and method of providing structural support to the battery enclosure. The battery enclosure includes a base having a first sidewall and a second sidewall opposite the first sidewall. The support beam extends from the first sidewall to the second sidewall. The support beam includes a body having a first beam end and a through passage. An internal stabilizer disposed within the through passage at the first beam end. The internal stabilizer includes a first stabilizer sidewall extending from a first stabilizer end to a second stabilizer end, a second stabilizer sidewall extending from the first stabilizer end to the second stabilizer end, and a bridge connecting the first stabilizer sidewall to the second stabilizer sidewall at the second stabilizer end.

A sill frame arrangement for a vehicle body arrangement includes: a battery arrangement provided in a floor region of the vehicle body arrangement, which has at least one frame arrangement having frame longitudinal members and frame cross members which surround and support at least one battery module, the frame longitudinal members resting on sill elements of a sill arrangement, the sill arrangement including wall elements which form sill chambers. Over an entire height of the sill arrangement, only one wall element directed toward the frame arrangement is provided, at least one additional sill element being provided on each sill element, the sill element and the at least one additional sill element being integrally bonded and interlockingly connected to one another.

A vehicle chassis platform including: a frame having a front frame end, a rear frame end, a longitudinal frame axis, an upper frame surface, a bottom frame surface, a first longitudinal lateral frame surface and a second longitudinal lateral frame surface, wherein the upper frame surface is substantially flat; and two or more mechanical connection assemblies each coupled to one of the first and second longitudinal lateral surfaces, each of mechanical connection assemblies to couple a vehicle corner module (VCM) to the frame and to transfer mechanical loads between the frame and the VCM when the VCM is coupled to the frame.

A protective element (1) named shield element for a battery pack of an electric or hybrid vehicle, wherein the protective element (1) includes a securing device (2) configured to removably secure the shield element (1) both to the battery pack and to a body (11) of the vehicle.

A battery pack houses battery stacks vertically in a plurality of stages. The battery pack includes a lower casing, a holder formed of leg portions attached to the lower casing in front and back of the battery stacks in the lower stage and a frame attached on upper portions of the leg portions, and a plate member that connects the lower casing and the frame of the holder. The battery stacks in an upper stage are arranged on top of the frame along the length of the vehicle.

A cooling structure of a vehicle battery unit includes: a plurality of battery modules; a plurality of battery cooling units; a supply pipe; a discharge pipe; and a battery case. The supply pipe includes a supply pipe portion which passes between the at least two battery modules arranged in the vehicle width direction and connects the plurality of battery cooling units. The discharge pipe includes a discharge pipe portion which passes between the at least two battery modules arranged in the vehicle width direction and connects the plurality of battery cooling unit. The supply pipe portion and the discharge pipe portion have bellows pipe portions which are made of resin and can be expanded or contracted in the front-rear direction and curved pipe portions which are made of resin and bend in the vehicle width direction.

A variable body vehicle may include a drive module having drive the vehicle wheels provided at a lower portion of the drive module; a body module coupled to an external side of the drive module and forming an internal space of the vehicle; and a battery-mounting portion formed in the drive module or the body module to mount a battery therein, providing electric power to the battery when the battery is mounted, and determining a driving mode of the vehicle by allowing the battery to be selectively mounted in the drive module, wherein a body of the vehicle is variable by a combination between the drive module and the body module according to a purpose of use.

A floor assembly for a motor vehicle has a front chassis module, in particular a front axle support, and a rear chassis module, in particular a rear axle support, as well as a housing of a stored electrical energy source, which is situated between the chassis modules as seen in the longitudinal direction of the floor assembly. The floor assembly includes at least one terminating component via which the housing of the stored electrical energy source can be fixed to a body part of the motor vehicle. The at least one terminating component is designed as a constituent part of at least one of the chassis modules. A motor vehicle includes such a floor assembly.

A battery unit for a vehicle is provided. The battery unit includes a lower case having two battery compartments arranged in a direction toward opposite sides of the vehicle, respectively, and a connecting portion bent to be convex upwardly between the two battery compartments. A reinforcing structure is disposed on the connecting portion. Two battery modules are installed in the two battery compartments, respectively and a power wire is electrically connected to at least one of the two battery modules and extends from one of the two battery compartments to the other one of the two battery compartments through the connecting portion.
