An energy storage housing for assembly on the lower face of a vehicle includes a first sub-housing which surrounds a first plurality of energy storage modules, a second sub-housing which surrounds a second plurality of electric energy storage modules, and a connection channel which connects the first sub-housing to the second sub-housing. The connection channel has a variable length. A vehicle is equipped with such an energy storage housing or a set of energy storage housings, wherein in a set all first sub-housings of the set are identical, all second sub-housings of the set are identical, and the connection channels of the energy storage housings of the set have different lengths.

A vehicle includes: a power equipment unit including a power equipment, a cooling mechanism for cooling the power equipment, and a case for accommodating the power equipment and the cooling mechanism; and an exhaust duct disposed on a floor panel, wherein the cooling mechanism discharges air, which has cooled the power equipment, into a passenger compartment through the exhaust duct. One end of the exhaust duct is connected to a duct connection portion of the case, and the other end of the exhaust duct is connected to a treading guard member which faces the floor panel to form a channel of air.

Safe, three-wheeled tilting scooter or motorcycle frames with two front steerable, non-tilting wheels are described herein, as well as three-wheeled tilting vehicles with various propulsion systems mounted on such frames are also disclosed. Said vehicles are preferably non-polluting, such as electric or fueled by hydrogen.

A work vehicle includes a battery that outputs a DC power, at least two electric motors, and at least two inverters, each inverter being configured to convert the DC power from the battery into an AC power and to supply the AC power to one of the electric motors. The work vehicle further includes an accommodation box attachable/detachable to/from the vehicle body, the accommodation box accommodating a plurality of electrical equipments including the inverters.

A vehicle underbody structure includes a pair of rockers that are provided on both vehicle width direction sides of a vehicle underbody and extend in a vehicle front-rear direction, a battery that is disposed centrally in a vehicle width direction center between the pair of rockers and is disposed above a vehicle floor and on the lower side of a seat, a fuel tank that is disposed in the vehicle width direction center between the pair of rockers and is disposed under the vehicle floor and further toward a rear side of the vehicle than the battery, and a waste pipe that is coupled to a drive unit provided at a vehicle front side of the battery and extends in the vehicle front-rear direction between the battery and one of the rockers.

A mounting system for an electric vehicle includes a front cross beam extending from a right side of a passenger compartment of the electric vehicle to a left side of the passenger compartment. The mounting system includes a rear cross beam extending from the right side to the left side. An underside of each of the front cross beam and the rear cross beam defines a plurality of mounting features configured for mounting a battery assembly to an underside of the electric vehicle. A plurality of seat rails extend across and mounted to the front cross beam and the rear cross beam, the plurality of seat rails being configured for mounting seats within the passenger compartment.

Provided is a work vehicle in which a seat support frame that supports a driver seat is equipped on a vehicle body frame, the vehicle body frame includes: a front portion vehicle frame at which a floor surface of a driving portion is provided; and a rear portion vehicle frame disposed at a position higher than the floor surface of the driving portion and rearward of the front portion vehicle frame. An engine is equipped below the rear portion vehicle frame, a battery that supplies power to an electric motor is equipped above the front portion vehicle frame and below the seat support frame, and a frame portion of the seat support frame that exists above the battery at a position opposing the battery is configured to be detachable from another frame portion that is fixed to the vehicle body frame.
