A fuel gas tank arrangement in a vehicle. The fuel gas tank arrangement comprises a fuel gas tank for holding a pressurized fuel gas volume, and a valve configured to ventilate fuel gas from the fuel gas tank into ambient surroundings. The valve comprises a controllable valve actuator communicatively connected to a control unit. The valve actuator is configured to open the valve to a determined opening degree for controlling a flow rate of ventilated fuel gas. The disclosure also relates to method for safety ventilation of fuel gas from a fuel gas tank arrangement.

There is provided a fuel cell vehicle, including a high voltage system disposed in a front compartment of the vehicle, and a first protruding portion that protrudes in a left-right direction of the vehicle toward a vehicle body of the vehicle further than a portion of the high voltage system that is closest to the vehicle body, and is fixed to the high voltage system, in which, when the vehicle is placed on a horizontal plane, the first protruding portion is arranged such that a position of a first most-protruded portion of the first protruding portion that protrudes most toward the vehicle body in a height direction is located at the same position or higher than a center of gravity of the high voltage system.

A system for powering an electric vehicle includes two independent rechargeable batteries. Each battery of the two independent rechargeable batteries includes one or more battery cells. There is circuitry for charging each of the two independent rechargeable batteries and circuitry for drawing electrical energy from one or both of the two independent rechargeable batteries such that during normal operation of the electric vehicle, a first battery of the two independent rechargeable batteries is charged from any available charge potential (e.g., power from generators or solar power) and a second battery of the two independent rechargeable batteries is utilized to power the electric vehicle.

The present invention relates to a holding frame for attaching high-pressure storage tanks to a vehicle. Also disclosed are high-pressure fuel storage systems including the holding frame, as well as vehicles including the high-pressure fuel storage system.

A fuselage portion of or for an aircraft. The fuselage portion comprises an aircraft component which is installed in a shell of the fuselage portion by a plurality of connector elements. Therein, a respective first end of each connector element is held in an associated bore b running through the shell, and a respective second end of each connector element is joined to the aircraft component by a joint providing the respective connector element with a margin of swiveling relative to the aircraft component. Also an aircraft comprising such a fuselage portion, and a method for assembling such a fuselage portion.

An automotive hydrogen storage tank support system for a vehicle includes: a floor; a pair of side sills mounted on lateral edges of the floor, respectively; and a support frame mounted on the floor and supporting a hydrogen storage tank The support frame includes a pair of longitudinal members, and a plurality of transverse members connecting the pair of longitudinal members to each other, at least one transverse member among the plurality of transverse members has a pair of extension portions respectively extending from opposite ends thereof toward the pair of side sills, and each extension portion is joined to a corresponding side sill of the pair of side sills.

A vehicle including a vehicle frame with an upper frame edge, a front axle with one front wheel, a rear axle with a rear wheel and a cryogenic container arranged laterally of the vehicle frame, and the cryogenic container is arranged in an installation space available, and a connection line runs to the cryogenic container or to an operating component of the cryogenic container located in the installation space through one of the following spandrels outside of the installation space available: through a rear wheel spandrel between the installation space and the rear wheel; through a front wheel spandrel between the installation space and the front wheel; through a lower construction spandrel between the installation space and an extruded triangle above the road; or, through a semi-trailer spandrel between the installation space and a pivoting region of a semi-trailer mounted on the vehicle.

The invention concerns a method for optimization of the energy consumption of a motor vehicle (2) comprising a fuel or hydrogen tank, a battery and/or super-capacitors (30), a thermal engine (M) or a fuel cell (P), an electrical machine (ME), a plurality of devices, each characterized by at least one variable of state, and a computer (4) configured to control the traction chain of the motor vehicle (2) over a predetermined distance, and being able to control the thermal engine (M) or the fuel cell (P), the electrical machine (ME) and/or the devices by the emission of a series of set-points. The invention also concerns a computer (4) and a computer program product for implementation of such a method, as well as a motor vehicle (2) comprising such a computer (4).
