An electrical vehicle including a vehicle body, a passenger compartment, a chassis supporting the passenger compartment, a plurality of wheels and at least one electrical motor for driving the wheels. A battery compartment of the vehicle is configured to removably mount therein a plurality of more than two rechargeable batteries which are movable into position in the battery compartment by a battery conveyor system which has a battery access opening through which batteries are installed or removed, one by one, to and from the battery compartment. In the battery compartment, a connection mechanism effects the needed mechanical and electrical connections. An overall control system controls the conveyor system and the connection mechanism to enable rapid replacement of the removable batteries, whereby an electrical vehicle can be instantly driven, even after its batteries have been discharged by a replacement of the discharged batteries and the installation of freshly charged batteries.

A computer that includes a processor and memory which stores instructions executable by the processor. The instructions include: initiate, from a vehicle, a fuel delivery request for fuel delivery by an unmanned aerial vehicle (UAV); in response to the initiation, instruct a communication module in the vehicle to transmit a beacon signal to enable the UAV to locate the vehicle; and coordinate a docking procedure between the UAV and the vehicle to receive fuel from the UAV.

A covering of an outer sill of a vehicle, in particular a motor vehicle, has a covering region and a mounting region, which extend between first and second ends of the covering along a direction of longitudinal extension. The mounting region extends in a first direction of transverse extension perpendicular to the direction of longitudinal extension and has mounting elements in order to be able to be mounted on an underside of the outer sill for a mounted state. The mounting region has a lateral edge facing away from the covering region in the direction of longitudinal extension, which has recesses between mounting elements, which are formed such that sections of the lateral edge of the mounting region extend in a recessed manner in the first direction of transverse extension towards the covering region.

A motor module for modularly making a front and/or rear electric axle, comprising an electric motor generator and a gear train enclosed in a gearbox case permanently fixed to a stator of said electric motor-generator, the module having an L-shape. Electric axle comprising a pair of L-shaped modules for making a T-shaped front electric axle and a U-shaped rear electric axle.

A battery pack lift system includes: a frame having nutrunners mounted thereon according to a battery pack fastener pattern for a vehicle; a lift configured to raise and lower the frame with regard to the vehicle; a first air bearing positioned between the frame and the lift, the first air bearing configured to allow relative movement between the frame and the lift; and a second air bearing positioned on the frame, the second air bearing configured to allow relative movement between a battery pack and the frame.

A vehicle lower portion structure includes a pair of rocker panels, the rocker panels being separated from each other in a vehicle width direction and extending in a vehicle front-rear direction, an intermediate cross member disposed between the rocker panels and extending in the vehicle width direction, an intermediate connecting member disposed in an end portion of the intermediate cross member in the vehicle width direction and provided with a first contact portion which is contact with the rocker panel and a second contact portion which is contact with the intermediate cross member, a first bonding portion bonding the first contact portion to the rocker panel, and a second bonding portion bonding the second contact portion to the intermediate cross member.

A body floor structure (1) for a motor vehicle having a traction battery (2) includes a first longitudinal member (3) and a second longitudinal member (4) that extend in a vehicle longitudinal direction. A floor panel (5) spans between the two longitudinal members (3, 4). A central tunnel (6, 6) extends in the vehicle longitudinal direction and has a cavity (60, 60) and is configured for receiving equipment components of the motor vehicle. The traction battery (2) is arranged on a lower side of the body floor structure (1), and the cavity (60, 60) of the central tunnel (6, 6) is designed to be open in the direction of a vehicle interior (7).

The invention relates to a system for installation of traction batteries for a vehicle having a chassis comprising at least one load-carrying frame member. A front bracket member and a rear bracket member are adapted to be secured to and project from the frame member of the vehicle for receiving a traction battery between the front bracket member and the rear bracket member. The system also comprises a first and a second slider adapted to be connected to a front and a rear side, respectively, of a traction battery. The sliders are adapted to be mated with the bracket members subsequently to the sliders having been connected to the traction battery, thereby enabling the traction battery by means of the connected sliders to be received by the bracket members and be moved towards the frame member of the vehicle.

The present disclosure relates to a battery assembly for a vehicle comprising a pair of longitudinally extending frame rails, the battery assembly comprising a first and a second vehicle battery module, the first vehicle battery module being stacked vertically on top of the second vehicle battery, wherein the battery assembly is configured to be connected to the vehicle vertically below the frame rails by attaching an upper surface of the first vehicle battery module to a horizontally extending portion of a pair of brackets, the pair of brackets being attachable to a respective one of the longitudinally extending frame rails.
