A concrete mixer vehicle includes a chassis, a tractive assembly coupled to the chassis and configured to propel the concrete mixer vehicle, a mixing drum rotatably coupled to the chassis, and an electromagnetic device configured to convert electrical energy to mechanical energy to drive the tractive assembly. In a first configuration, a first battery module is removably coupled to the chassis and configured to provide the electrical energy to the electromagnetic device, and in a second configuration, the first battery module is removed from the chassis and replaced with a second battery module, the second battery module removably coupled to the chassis and configured to provide the electrical energy to the electromagnetic device.

A reinforcing unit is configured to be inserted into a side sill of a vehicle body. The reinforcing unit includes a center core formed so as to extend in a longitudinal direction of the vehicle body, and a pair of cover cores formed so as to extend in the longitudinal direction of the vehicle body and arranged so as to cover an upper portion and a lower portion of the center core.

A vehicle lower structure includes: a floor of a vehicle; a cross member that is provided under the floor and extends in a vehicle width direction; a battery pack mounted under the floor; a suspension member with which a movable part of a suspension is connected so that the movable part is able to operate, the suspension member being positioned on a front side or a rear side of the battery pack and fixed to a vehicle body; and a hanging bracket that is hung from the cross member and is connected with an end surface of the battery pack on a suspension member side by a fastening component such that the hanging bracket supports the battery pack in a hanging manner. The battery pack and the hanging bracket are connected with each other below the suspension member.

A battery pack includes: a plurality of battery modules arranged side by side along a first direction orthogonal to an up-down direction; a housing case configured to house the plurality of battery modules; a wire harness electrically connected to the plurality of battery modules and routed in the housing case; and a reinforcing portion provided within the housing case and configured to reinforce the housing case. The reinforcing portion includes a plate-shaped portion arranged separately from the plurality of battery modules and extending along the first direction. The plate-shaped portion has a lower surface facing the plurality-of-battery-modules side, and an upper surface located on an opposite side of the lower surface. The wire harness is routed along the upper surface of the plate-shaped portion.

A tractor trailer battery system having a battery compartment containing one or more battery units which house one or more battery cells, electrical leads from the battery units to a trailer mounted controller in electrical communication with a cab mounted controller which is in electrical communication an electric motor or hybrid engine system. The battery system allows for either the trailer mounted controller or the cab mounted controller to provide principal communication to the electric motor or hybrid engine system.

There is provided a vehicle lower section structure including a pair of rockers respectively provided at both vehicle width direction outer sides of a floor panel of a vehicle so as to extend in a vehicle front-rear direction, each of the rockers being configured including: an outer section that is positioned at the vehicle width direction outer side; an inner section that is integrally formed with the outer section, that is positioned at a vehicle width direction inner side, and that forms a closed cross-section section together with the outer section; and a first shock absorption section that is integrally formed with the outer section and the inner section, and that spans in the vehicle width direction between the outer section and the inner section within the closed cross-section section.

This disclosure relates to an electrified vehicle with a vibration isolator within a frame of the vehicle and a corresponding method. An electrified vehicle according to this disclosure includes a frame with a rail, a vibration isolator within the rail, and a battery pack connected to the rail by way of the vibration isolator. Among other benefits, mounting the vibration isolator within the rail increases the amount of available packaging space.

The present disclosure relates to a battery system for a hybrid or an electric vehicle. Another aspect of the present disclosure provides a battery assembly designed for easy and quick exchange of battery assemblies enabling a vehicle to resume driving much more quickly than traditional charging permits.

A vehicle battery case is provided. The battery case includes a lower panel and at least one transverse member that is disposed on the lower panel to increase transverse rigidity. Additionally, at least one longitudinal member is disposed on the lower panel to increase longitudinal rigidity, and a sidewall member is attached to an upper surface of the lower panel along a rim of the lower panel.

This disclosure details mounting systems and associated methods for mounting a battery pack to an electrified vehicle. An exemplary electrified vehicle may include a frame, a battery pack, and a mounting system for mounting the battery pack to the frame. The mounting system may include one or more side rails. Each side rail may include a predefined crush initiator configured to plastically deform for absorbing and transferring energy during vehicle impact loading events.
