The invention relates to a safety valve system (10a; 10b; 10c) for a combustion gas vehicle (11), having: an excess pressure valve unit (13) with a first gas outlet (14) for discharging excess pressure gas (29) out of a combustion gas tank (12) of the combustion gas vehicle (11) in a first outlet direction (RI) and at least one additional gas outlet (15, 16, 17) for discharging excess pressure gas (29) out of the combustion gas tank (12) in at least one additional outlet direction (R2) which differs from the first outlet direction (RI); a state detection unit (18) for detecting a vehicle position and/or a vehicle orientation of the combustion gas vehicle (11) and/or a surroundings state of the combustion gas vehicle (11); and an adjustment unit (19) for adjusting the discharge of excess pressure gas (29) through the first gas outlet (14) and/or through the at least one additional gas outlet (15, 16, 17) on the basis of the detected current vehicle position, the detected current vehicle orientation, and/or the detected surroundings state. The invention additionally relates to a combustion gas vehicle (11), to a computer program product (26), and to a storage means (26) with a computer program product (26) stored thereon.

A hydrogen storage apparatus of a vehicle driven by a fuel cell comprising hydrogen storage tank holding apparatuses 8, 9 having pluralities of hydrogen storage tank insert parts 10. When the replaceable hydrogen storage tank 20 is inserted into the hydrogen storage tank insert part 10, the hydrogen outflow part 28 of the hydrogen storage tank 20 is coupled with the hydrogen inflow part 23 connected to the fuel cell 40. The grippable handle 24 is formed at the end portion of the hydrogen storage tank 20. A work of inserting the hydrogen storage tank 20 into the hydrogen storage tank insert part 10 and a work of coupling the hydrogen inflow part 23 and the hydrogen outflow part 28 is performed by gripping the handle 24.

An energy storage assembly for a motor vehicle, including a traction battery for storing electrical energy. A flexible pressure element, which is filled with gas or liquid is disposed on the outside of the traction battery or on the inside of a covering component for the traction battery, the gas or the liquid is contained at atmospheric pressure within the flexible pressure element. A pressure sensor is connected to the flexible pressure element, and by which collision-induced pressure fluctuations in the flexible pressure element can be sensed.

The invention relates to a device for storing compressed gas, for example hydrogen or natural gas, comprising a storage line (1) to which at least one compressed gas container (2) is connected via a valve (3). According to the invention, the storage line (1) has at least one connection port (4) for the gas-tight connection of the at least one compressed gas container (2), and a safety element (5), which has a filter function and a shutoff function, is integrated in the connection port (4). The invention further relates to a vehicle having a device according to the invention for storing compressed gas.

A method for manufacturing a tank unit includes performing a pressure resistance inspection on each of a plurality of high pressure tanks before connecting the high pressure tanks, and connecting a gas flow path to the high pressure tanks that have passed the pressure resistance inspection.

A gas discharge device, for a vehicle powered by compressed gas, includes: a gas manifold having a hollow body and including at least one port configured to be in fluid communication with a compressed gas tank, and an opening for discharging gas into the atmosphere; and a pipe configured to connect the port to the compressed gas tank. The pipe is freely translatable in the port to enable a first end of the pipe to move translationally along an axis in the port.

A fuel cylinder, such as a high-pressure fluid storage tank, is provided with dual-inlet refilling capabilities. The storage tank may include a main body section with a first domed end portion and a second domed end portion disposed at opposite portions of the main body section. A first inlet assembly and a second inlet assembly are provided at the respective first domed end portion and the second domed end portion. Each inlet assembly is configured to provide fluid communication between a supply of a high-pressure fluid and an interior of the storage tank. Each inlet assembly may include a boss and a tank valve, with each tank valve being in fluid communication with the compressed fluid receptacle. During filling of the storage tank, the high-pressure fluid travels through a compressed fluid receptacle and enters the interior of the storage tank simultaneously through each of the first and second inlet assemblies.
