A vehicle body structure for an electric vehicle includes: a battery disposed at a center lower portion of a vehicle body; a side sill being hollow and extending in a vehicle body front-rear direction outside in a vehicle width direction of the battery; a bridge beam member being hollow, disposed below the side sill and outside in the vehicle width direction of the battery, extending in the vehicle body front-rear direction, and having a cross section perpendicular to the vehicle body front-rear direction formed as a closed cross section; and at least one bridge pier member made of steel, extending in the vehicle width direction from the battery toward the bridge beam member, and having a cross section perpendicular to the vehicle width direction forming at least a part of a closed cross-sectional shape.

A system and method for manufacture of the system are provided. In one example, the system comprises a first component, a second component securing the first component to a portion of the system, and a flexible strip with an abrasion resistant coating including a copolymer. The first component or the second component includes a corrosion coating on an exterior surface and the flexible strip is interposed between a surface of the first or second component and the corrosion coating.

An electrically operated vehicle having a traction battery installed on the underside of the vehicle and a body side structure which has a door entry region on a lateral rocker panel. The vehicle has at least one shielding element which at least partially closes a free distance between the underside of the vehicle and a vehicle standing plane in the event of battery damage, so that the door entry region is shielded from the damaged traction battery installed on the underside of the vehicle.

An embodiment is directed to a contact plate configured to establish electrical bonds between battery cells in a battery module, including at least one primary conductive layer, and a set of bonding connectors that are configured to provide direct electrical bonds between the contact plate and terminals of a group of battery cells, the set of bonding connectors being configured to connect the group of battery cells in parallel with each other, wherein at least one bonding connector in the set of bonding connectors is configured with a higher fuse rating than each other bonding connector in the set of bonding connectors so as to contain arcs among the set of bonding connectors to the at least one bonding connector.

The invention relates to a protecting member for a battery structure of an electric vehicle. The protecting member includes a top belt, a bottom belt and a core arranged between and interconnecting the top belt and the bottom belt. The core is at least partially made from a porous and fibrous structural material, such as plywood.

Rocker structure (R1-R3) for a vehicle comprising a first steel profile (1) and a second steel profile (2) having the longitudinal direction (L) of the vehicle so that a channel (CH) is defined therebetween, the first and second profiles(1, 2) comprising a vertical central section (13), the rocker structure (R1-R3) comprising a first impact absorption element (3) arranged in the channel (CH), wherein the first impact absorption element (3) is a closed steel profile wherein an upper lobe (31) and a lower lobe (32) joined by a central joining section (33) are defined, the upper lobe (31) being located closer to the upper joining flanges (11, 21), the lower lobe (32) closer to the lower joining flanges (21, 22). The invention also relates to a method for obtaining the rocker structure and to vehicles provided with the inventive rocker structure.

An electricity storage device has an electricity storage element sealed in a package member of a laminate material including a thermal adhesive resin layer. The package member has a housing portion having a substantially rectangular opening and formed to have a predetermined depth; a flange portion protruding outward from the circumferential edge of the opening; and a lid portion covering the opening and thermally bonded to the flange portion. The electricity storage element has a pair of electrode terminals protruding respectively from opposite longer-side edges of the opening and held between the flange portion and the lid portion.

An electric vehicle may include: a body comprising a compartment on a front side of a cabin; a component frame located in the compartment, and connected to the body; and a circuit case located on the component frame, comprising therein a control circuit configured to control a traction motor, and constituted of metal. The component frame may comprise: a plurality of crossmembers extending along a vehicle left-right direction; and a connection member connecting the plurality of crossmembers to each other. The plurality of crossmembers may comprise a rear crossmember which is a rearmost crossmember of the plurality of crossmembers. The circuit case may be on the front side of a rear end of the rear crossmember in a top view.

A vehicle-body structure prevents a submarine phenomenon of a passenger during a front-end collision and achieves lowering of the vehicle floor-height while maintaining a sufficient number of mounted batteries. Embodiments of a vehicle-body structure include a seat pan that is formed at part of a floor panel and on which a seat cushion is placed, and a battery arranged below the seat pan. A bulging portion that bulges upward is formed at a vehicle front-side of the seat pan. An accessory member is housed inside the bulging portion. An upper-end portion of the accessory member housed in the bulging portion 4 is positioned farther on the upper-side than a lower-end portion of the bulging portion 48a.
