A pressure vessel mounting system for mounting a pressure vessel to a vehicle chassis is disclosed. In various embodiments, the system includes a first end frame; a second end frame spaced a distance from the first end frame, the distance being sufficient to receive a pressure vessel between the first end frame and the second end frame; a first side frame extending between the first end frame and the second end frame, the first side frame configured for coupling to a first chassis rail of the vehicle chassis via at least one of the first end frame and the second end frame; and a second side frame extending between the first end frame and the second end frame. Via use of the pressure vessel mounting system, impact damage to pressure vessels may be reduced and/or eliminated.

A support structure which includes tank formed rack comprising at least two modules affixed to each other via attached bases and a method of reduced weight storage of fuel tanks also for use in motor vehicles wherein the fuel tanks via attached bases are used to form a portion of the rack superstructure.

A method for assembling a tank assembly for a vehicle. The tank assembly comprises a plurality of tanks comprising a plurality of tank subsets comprising a first tank subset and a second tank subset. The first and second tank subsets are adapted to be adjacent in the tank assembly.

A cooperating rack structure comprising at least two modules affixed to legs and a method of reduced weight vertical storage of fuel tanks for use in motor vehicles wherein the fuel tanks form a cooperating portion of the rack superstructure.

A drive system for a vehicle includes a frame, an electric motor, and an energy storage unit suspended from the frame of the vehicle. The energy storage unit includes at least two energy modules including a first energy module having a first cuboid fuel tank and a first cuboid energy storage device including at least one battery. The at least two energy modules further include a second energy module having a second cuboid fuel tank. The at least two energy modules are connected to each other such that the first cuboid fuel tank and the second cuboid fuel tank are connected to opposite sides of the first cuboid energy storage device.

A tank arrangement, wherein the fuel tank body comprising a main portion and a secondary portion which comprises an upper portion and an intermediate portion arranged successively along the vertical direction, configured to define a housing to accommodate the urea tank, wherein in an engaged configuration, the urea tank is arranged under the upper portion of the secondary portion along the vertical direction, in abutment on the intermediate portion along the transverse direction, and in abutment on the primary portion along the front-rear direction, wherein the urea tank comprises a urea drain on a lower portion of the urea tank along the vertical direction, the secondary portion of the fuel tank comprises a groove that extends through the fuel tank along the transverse direction, adapted to allow ducts to go through the secondary portion of the fuel tank along the transverse direction to be connected to the urea tank.

The disclosure concerns a fastening device for fastening a first and a second container to a structure of a vehicle, the fastening device comprises: an elongated member with external engagement members, a first abutment, a displaceable member, a guide arrangement, comprising a second abutment, a holed member, and a resilient compressible member. The elongated member extends along an axis and the displaceable member, the guide arrangement, the resilient compressible member, and the holed member are aligned along the axis. The elongated member extends through the displaceable member and at least partially through the guide arrangement for engagement between external engagement members of the elongated member and internal engagement members of the holed member for compression of the resilient compressible member.

The technology disclosed here relates to a pressure container system. The pressure container system includes a plurality of pressure containers for storing fuel and at least one load-distributing base layer. The load-distributing base layer is advantageously arranged between a lower base plate and the plurality of pressure containers. The load-distributing base layer is designed such that forces F, which act locally on the lower base plate and which act on the lower base plate substantially in the direction of the vehicle vertical axis Z, can be distributed to the plurality of pressure containers.
