摘要:
A method is provided for enhancing in-service structural performance of a sheet metal component incorporating a discontinuity. The method comprises heat-treating a zone of the sheet metal component a predetermined distance from the discontinuity thereby changing the strength and ductility of the zone and shifting the deformation induced in the sheet metal component by a subsequent deformation event away from the discontinuity to the zone.

A structural assembly for an electric vehicle includes a battery structure, a pair of mounting structures, lower fasteners and upper fasteners. The battery structure is configured to house power storage units. Each mounting structure is secured to a respective side of the battery structure. Each lower fastener extends through a lower portion of a respective mounting structure and a bottom portion of a respective rocker of the vehicle body. Each upper fastener extends through an upper portion of the respective rocker and a top portion of the respective mounting structure. The upper fasteners secure the battery pack and the vehicle body at an upper attachment point and the lower fasteners secure the battery pack and the vehicle body at a lower attachment point. The lower attachment point is vertically offset from the upper attachment point.

A vehicle includes an integrated floor and traction battery support assembly. The assembly includes a floor panel and cross-members each having an upper portion attached to a lower surface of the floor panel and extending laterally across the floor panel. The assembly further includes a battery tray attached to lower portions of the cross-members and cooperating with the lower surface to define a battery-pack enclosure. A battery pack is disposed in the enclosure.

摘要:
A vehicle includes members spaced from each other and elongated along a vehicle-longitudinal axis. A battery module includes end plates spaced from each other along the vehicle-longitudinal axis. Battery cells are sandwiched between the end plates and a connector extends from one end plate to the other end plate. The end plates extend from one of the members to the other of the members.
摘要:
A vehicle includes a vehicle frame elongated along a longitudinal axis. The vehicle frame includes a first rail and a second rail spaced from each other and each elongated along the longitudinal axis. The vehicle frame includes a longitudinal beam between the first and second rails and elongated along the longitudinal axis. The vehicle includes a vehicle body. The vehicle body includes a cross-beam directly connected to the longitudinal beam and to the first and second rails.
