The present disclosure generally relates to a multiple receptacle fuel filling and storage system in a vehicle and/or powertrain, and a method of using the same.

A flow control panel configured to control the flow of fuel from a storage bank to a dispense includes a cold fuel controller, a dispenser port, and a processor. The cold fuel controller is configured to control the flow of cold fuel from a cold fuel line. The dispenser port is in fluid communication with the cold fuel controller. The processor is configured to receive an indication of fuel temperature within a dispenser and activate the cold fuel controller to allow the cold fuel from the cold fuel line to flow to the dispenser port when the indication of fuel temperature within the dispenser exceeds a maximum temperature determined by the dispenser.

Mobile cryogenic tank for transporting cryogenic fluid, notably liquefied hydrogen or helium, comprising an internal shell intended to contain the cryogenic fluid, an external shell arranged around the internal shell and delimiting a space between the two shells, said space containing a thermal insulator, the first shell having a cylindrical overall shape extending along a central longitudinal axis (A), when the tank is in the configuration for transport and use, the central longitudinal axis (A) being oriented horizontally, the tank comprising a set of temperature sensors measuring the temperature of the fluid in the internal shell, characterized in that the set of temperature sensors is situated on the external face of the internal shell and measure the temperature of said shell, the set of temperature sensors comprising a lower sensor positioned at the lower end of the internal shell situated below the central longitudinal axis (A), the set of temperature sensors further comprising a plurality of intermediate sensors distributed over two lateral faces of the internal shell on each side of the central longitudinal axis (A), the plurality of intermediate sensors being distributed vertically between the lower end of the internal shell situated below the central longitudinal axis (A) and the upper end of the internal shell situated above the central longitudinal axis (A).

The invention relates to a pressurized fluid storage and dispensing assembly (1) for a vehicle, comprising: a plurality of pressurized fluid reservoirs (3), each reservoir (3) comprising a first end piece (13) provided with at least one fluid passage duct configured for dispensing fluid from the reservoir (3) and for filling the reservoir (3), a use collector duct (5) which comprises an opening (19) for supplying and/or dispensing fluid and a plurality of orifices, each orifice being configured to be fluidically connected to a reservoir (3) via its fluid passage duct, and an electrically operated valve (7) which is arranged at one end of the use collector duct (5) and selectively closes or opens the fluid passage through the opening (19).

The invention also relates to a vehicle comprising such a storage and dispensing assembly (1).

A pressure vessel arrangement includes a plurality of pressure vessels configured to store fuel, and a valve arrangement with at least one valve and a plurality of tank connectors. In the pressure vessel arrangement each pressure vessel of the plurality of pressure vessels is connected to one of the tank connectors. Further, in the pressure vessel arrangement the valve arrangement connects the tank connectors directly to one another and to the at least one valve, such that a fluid exchange which is not impaired at any time by way of a valve is brought about between the individual pressure vessels.

An apparatus for controlling a fuel tank according to an embodiment of the present disclosure may include a fuel tank having a plurality of volumes, and a controller that controls a charging state of a fuel charged in the fuel tank and selectively controls use of the fuel charged in the plurality of volumes based on an amount of the fuel used and a state of the fuel tank.

A management system includes a position detection unit which obtains a position of a work machine, a posture detection unit which obtains a posture of the work machine, an object detection unit which obtains a three-dimensional shape of a buried object, a position calculation unit which obtains a position of the buried object by using the position of the work machine obtained by the position detection unit, the posture of the work machine obtained by the posture detection unit, and the three-dimensional shape of the buried object obtained by the object detection unit, and an information acquisition unit which acquires buried object information including at least the position of the buried object obtained by the position calculation unit.
