A fuel system is provided that includes a fuel system frame and in some cases access steps. The frame can be mounted to a vehicle frame rail. Bracket assemblies can be coupled to the fuel system frame at a plurality of positions. The fuel tank can be mounted at neck portions thereof and can be supported on the frame rail between the neck portions, e.g., spaced a distance from the neck portions in a longitudinal direction of the fuel system. The access steps can be non-rectangular to provide a wide stepping portion even if the fuel system includes large tanks. The steps can be directly supported by an outside surface of the tank.

A fuel cell vehicle includes a first tank, a second tank, first and second valves for releasing gas, a gas passage for supplying gas to a fuel cell via the first and second valves, a pressure-reducing valve for decompressing the gas, side members disposed on the respective sides of the vehicle, and a motor disposed rearward of the second tank and configured to drive wheels. The first tank is not disposed downstream of the second tank, on the gas passage. The pressure-reducing valve is disposed in a region located rearward of a rear end of the second tank in a vehicle front-rear direction, forward of a rear end of the motor in the vehicle front-rear direction, and between one of the side members and an extended line extended in the vehicle front-rear direction from a side wall of the motor. The pressure-reducing valve is disposed on the second valve side.

A cable structure includes a first cable, a second cable, a communicating portion, and a ventilation-tube connecting portion. The first cable includes a first power line, a first connector, a second connector, and a first tube. The first tube covers the first power line and has a first space. The second cable includes a second power line, a third connector, a fourth connector, and a second tube. The second tube covers the second power line and has a second space. The first space communicates with the second space via the communicating portion. The ventilation-tube connecting portion is provided at the first tube or the second tube. The ventilation-tube connecting portion is connected to a ventilation tube through which the first space and the second space are ventilated.

A vehicle includes a motor, a power converter, a fuel tank, and a three-phase line. The motor moves the vehicle. The power converter is connected to the motor. The power converter is configured to convert electric power and to supply the converted electric power to the motor. The fuel tank is disposed between the motor and the power converter. The fuel tank has a tank bottom on a side of a bottom of the vehicle. The tank bottom has a recess. The three-phase line is provided in the recess. The motor is electrically connected to the power converter via the three-phase line.

A working vehicle, including: a driving unit into which a worker gets to perform driving, the driving unit being provided to a vehicle-body; a step on which the worker steps when getting in or out of the vehicle, the step being provided at an outer side of a floor of the driving unit with respect to a left-and-right direction of the vehicle-body; a fuel tank provided below the floor so as to be adjacent to the step; and a fuel tank supporting bracket which supports the fuel tank from below, wherein the step has an upper side step part, and a lower side step part, the upper side step part is attached to the floor, and the lower side step part is attached to the fuel tank supporting bracket.

There is provided a high pressure container including (i) a plurality of container bodies, each of the container bodies housing a fluid in a high pressure state and being able to release the fluid through a release portion, (ii) an opening section that is linked to the container bodies, and that opens at or above a predetermined opening temperature to release the fluid inside the container bodies, and (iii) a cover member that straddles the plurality of container bodies, that covers at least a portion of the plurality of container bodies, that is able to withstand a temperature of no less than the opening temperature, that is linked to the opening section, and that is capable of transmitting heat to the opening section.

A fuel tank system includes a fuel tank and a support structure. The support structure provides impact protection to the fuel tank. The support structure has mounting members, a bottom plate and a support member. The mounting members mount to the vehicle. The bottom plate is provided proximate a bottom wall of the fuel tank, wherein the bottom plate protects the fuel tank from being crushed or punctured and serves as a skid plate if ground contact is made. The support member extends between a respective mounting member and the bottom plate. The support member is configured to fail during impact, allowing the fuel tank to be moved downwardly and laterally by the energy of the impact to a position in which the fuel tank is substantially out of the path of the impact or protected by the chassis of the vehicle.

The subject matter of the invention is a battery unit (100) for a hybrid vehicle (200), with a battery housing (10) which has a front side wall (23) directed towards the front side (22) of the hybrid vehicle (200) and a rear side wall (24) directed towards the rear side of the hybrid vehicle (200), and with at least one battery module (11) which is arranged in the battery housing (10), wherein at least one fuel tank (12) is arranged in the battery housing (10).

A vehicle fuel tank mounting assembly configured to secure a vehicle fuel tank to a vehicle is described. The assembly comprises a first elongate securing member having at least a first fixing point attachable to a vehicle body. The elongate securing member extends at least partially around the fuel tank in an assembled configuration. The assembly comprises a support member having a first end attachable to the first fixing point, and a second end configured to engage at least one of the elongate member and a wall of the fuel tank at a point remote from the fixing point.

A transport vehicle configured to run on electricity generated by a fuel cell includes: a body having a cargo space for freight; a chassis frame located below the body and supporting the body; and a tank unit including a plurality of tanks that stores fuel gas to be used for power generation by the fuel cell and a connecting portion connecting the tanks, the tank unit being located between the cargo space and the chassis frame.
