This rear vehicle body structure includes a first floor cross member disposed on a vehicle front side with respect to a battery and connected to a rear side frame extending in a vehicle front-rear direction on an outer side in a vehicle width direction, and a second floor cross member disposed on a vehicle rear side with respect to the battery, in which the first floor cross member includes a widened part widened in the vehicle front-rear direction at an end portion and extending to a position at which it overlaps the battery, and a boundary part between the widened part and the rear side frame is disposed at a position at which it overlaps the battery in a side view.

A vehicle-body structure may include a floor panel, a center frame disposed to be higher than and away from the floor panel, and an air-conditioning device. The air-conditioning device may include an air distribution portion that is positioned higher than a front portion of the center frame and distributes generated air-conditioned air to each portion of an occupant space, and under-feet ducts that guide air-conditioned air to a lower side. The under-feet ducts each may extend downward from the upper side of the center frame through a vehicle-width-direction outer side of the center frame.

A locomotive being provided electrical energy from a rechargeable battery located on a separate carriage or in an alternative embodiment contained within the locomotive carriage. The rechargeable battery is optionally removable allowing a fresh rechargeable battery to be inserted to reduce down time.

Vehicle chassis with interchangeable performance packages and related methods. are disclosed herein. An example vehicle chassis disclosed herein includes a frame including a first chassis portion including a cavity, a battery platform coupled to first chassis portion, and a first subframe couplable within the cavity, the first subframe including a first motor and a first suspension assembly, and a second subframe couplable within the cavity, the second subframe including a second motor and a second suspension assembly, the second motor having a greater power than the first motor, the second suspension assembly having a greater stiffness than the first suspension assembly.

A frame assembly for an automobile and method of assembling same. The frame assembly includes a battery housing at least partially integral with an automobile frame. The frame includes longitudinal beams that extend between front frame rails and rear frame rails. The battery housing includes two portions, a upper cover integrated with the longitudinal beams and a base plate that connects to the upper cover or the longitudinal beams with a releasable connection. The base plate includes a connection flange that includes at least one seal. When connected, at least one battery module is enclosed in the battery housing.

A battery and capacitor assembly for a hybrid vehicle includes a plurality of battery cells, a plurality of capacitor cells, a cooling plate, a pair of end brackets, and a housing. The plurality of capacitor cells are arranged adjacent to the plurality of battery cells such that the plurality of battery cells and the plurality of capacitor cells form a cell stack. The pair of end brackets are disposed at opposite ends of the cell stack and are attached to the cooling plate. The pair of end brackets compress the plurality of battery cells and the plurality of capacitor cells. The housing is attached to the cooling plate and encloses the cell stack and the pair of end brackets.

Systems and methods are provided for end-to-end infrastructure for supporting use of swappable batteries in electric vehicles. An end-to-end infrastructure for supporting use of electric vehicles may include one or more battery-swapping fueling stations. Each battery-swapping fueling station is configured to maintain one or more swappable batteries configured for operation in the electric vehicles, charge each of the one or more swappable batteries, when not fully charged, and swap, using the one or more swappable batteries, at least one battery of at least one electric vehicle when the at least one electric vehicle is refueling at the battery-swapping fueling station.

A vehicle control unit includes a control unit connectable to a first power supply line of a vehicle, a load connectable to the control unit, a detachable internal rechargeable battery, and a housing configured to accommodate the control unit and the internal rechargeable battery therein. The control unit is configured to selectively supply, to the load, one of first power-supply electric power supplied from the first power supply line and second power-supply electric power supplied from the internal rechargeable battery according to a situation.

An energy storage device and structure for energy storage cells is provided that includes a plurality of energy storage cells, each of the energy storage cells having side surface areas. The plurality of energy storage cells are arranged in a pattern with each energy storage cell being spaced a specified distance apart from one another. An expandable material is adhered, by an adhesive backing, to at least a portion of the side surface areas of one or more of the energy storage cells, and the expandable material expands within and at least part of the specified distance.

A battery-retention system employs a retention jaw assembly and a battery-retention mechanism to secure a battery within a battery compartment of a material-handling vehicle. The retention jaw includes a battery-contact portion operatively associated with a barrier portion that is movable between a battery-retention position when the battery contacts the battery-contact portion and a battery-release position when the battery does not contact the battery-contact portion. The battery-retention mechanism includes a stopper block that is operable to be positioned within the battery compartment when the battery compartment door is in a closed position and operable to be positioned external to the battery compartment when the battery compartment door is in an open position.
