A vehicle understructure includes a hydrogen tank that is disposed along a longitudinal axis of a vehicle. At least an upper portion of the hydrogen tank is enclosed in a floor tunnel. The hydrogen tank includes dome portions that are disposed at both ends of a cylindrical center body portion of the tank, and at least one valve portion that protrudes from at least one of the dome portions. The vehicle understructure also includes a brace that extends along a transverse axis of the vehicle and is secured to transversely outer side portions of the floor tunnel. The brace is at least partially overlapped with at least one of the dome portions when viewed from the front or rear of the vehicle.

A high-pressure tank mounting structure includes a case that is disposed beneath a floor of a vehicle cabin and that has a bottom wall, a peripheral wall and a top wall; a plurality of high-pressure tanks that are accommodated so as to be lined up within the case; and a discharge hole that is formed at an upper portion of the case and discharges, to an exterior of the case, hydrogen that has permeated from the high-pressure tanks.

Methods and systems are provided for protective cover. In one example, the protective cover may be configured to protect a fuel delivery module and may include a domed cap. The domed cap may resistant forces exerted on the protective cover and maintain clearance between the domed cap and enclosed electronic ports of the fuel delivery module.

A motor vehicle has a pressure relief device that can be thermally activated, for the pressure relief of at least one pressure vessel. A body floor element is arranged at least partially between the passenger compartment or the cargo area and the pressure vessel. A pressure relief triggering device is designed to directly or indirectly bring about the pressure relief. The pressure relief triggering device is designed to absorb thermal energy from the passenger compartment or the cargo area in order to trigger the pressure relief device, without the thermal energy absorbed for the triggering having previously been transmitted to the pressure relief triggering device through the body floor element.

The technology disclosed by the invention relates to a pressure vessel system for a motor vehicle for storing fuel, comprising a plurality of pressure vessels (100) that are combined to a pressure vessel assembly (10), the pressure vessels (100), when mounted, being arranged substantially in parallel relative to each other, and the pressure vessels (100) being fluidically interconnected via a common fuel line (200).

The invention relates to a battery box arrangement for a vehicle, the arrangement comprising: a battery box configured to comprise at least one electric battery; at least one elongated beam element connected to the battery box; and at least one vibration damping element configured for connecting the at least one elongated beam element to a chassis frame of the vehicle; wherein the at least one elongated beam element is configured to extend transverse to the chassis frame of the vehicle; wherein a first end part of the at least one elongated beam element is connected to a first battery box module of the battery box, and wherein a second end part of the at least one elongated beam element is connected to a second battery box module of the battery box. The invention also relates to a vehicle with such a battery box arrangement

A vehicle lower portion structure has an internal combustion engine that is disposed on one side in a vehicle width direction in a power unit compartment, an inverter that is disposed on another side in the vehicle width direction in the power unit compartment, an exhaust pipe that extends in a vehicle front-rear direction through a dash panel separating the power unit compartment from a vehicle cabin, and is disposed within a floor tunnel that is provided in a central portion in the vehicle width direction at least at a position of the dash panel, and whose one end portion is connected to the internal combustion engine, a battery that is provided on a vehicle rear side of the dash panel, high-voltage power cables that extend in the vehicle front-rear direction on another side in the vehicle width direction and connect the inverter and the battery together.

The disclosure relates to an assembly for a vehicle, in particular for a hybrid electric vehicle. The assembly includes at least one fuel tank having the form of a saddle tank. The assembly further includes at least one traction battery that is arranged outside the fuel tank and is thermally connected to the fuel tank, and at least one fuel pump arranged in the fuel tank. The fuel pump can convey a fuel from within the fuel tank to an internal-combustion engine of the hybrid electric vehicle. To provide a cooling system for the traction battery, the traction battery can be thermally connected to an active tank portion of the fuel tank, in which the fuel pump is arranged. The traction battery can be connected to the active tank portion via a bridge portion of the fuel tank, which is connected in a communicating manner to a passive tank portion of the fuel tank. Fuel in the passive tank portion can be conveyed into the active tank portion.

A cylindrical hydrogen tank is housed under a floor tunnel, which is disposed at the center in a vehicle width direction of a floor panel along a vehicle front-back direction so as to protrude upward along a height direction, and includes a casing having a load bearing property. A seat cross member is disposed on a side of the hydrogen tank along the vehicle width direction. A seat pipe is joined to the seat cross member and disposed so as to extend along the vehicle width direction. The seat pipe and the seat cross member are arranged within the height of the hydrogen tank in a vehicle height direction, and also respectively located above and below the most outwardly protruded lateral end point in the vehicle width direction of the hydrogen tank.

A fuel cell vehicle provided with an exhaust duct structure is capable of reliably diluting hydrogen flowing into an exhaust duct. The fuel cell vehicle includes a vehicle body, an air-cooled fuel cell mounted in the vehicle body to generate power by allowing hydrogen gas and oxygen in air to react with each other, an exhaust duct through which exhaust air of the fuel cell is guided to a rear end of the vehicle body and is discharged outside the fuel cell vehicle, and a fan guiding air into the exhaust duct to dilute hydrogen in the exhaust duct.
