An open cabin electric wheeled vehicle includes a large-capacity driving battery having a volume energy density higher than the volume energy density of a lead storage battery, the large-capacity driving battery being configured to supply electric power to a driving electric motor. The vehicle also includes a fuel-type electric power generation apparatus that generates electric power using a fuel. As seen from a leftward direction or a rightward direction, between the large-capacity driving battery and the fuel-type electric power generation apparatus, a recess overlaps with a passage region which allows people or baggage to pass through of an entrance and exit opening portion having no door, so that a bottom end of a front wall portion, a bottom end of a rear wall portion, and a bottom portion are located further downward than a top end of the large-capacity driving battery which has a volume energy density higher than the volume energy density of a lead storage battery, and a top end of the fuel-type electric power generation apparatus.

The present invention relates to a machine, in particular wheel loader, with a cabin for the operator of the machine and with an engine compartment arranged behind the cabin, wherein the machine has a drive, which is operable using hydrogen or using energy obtained from hydrogen and wherein one or more tanks are present for receiving hydrogen, wherein the tank or tanks is/are arranged between the cabin and the rear of the machine in a hydrogen fuel system.

A vehicle may include a fuel cell system configured for generating electrical energy used in the vehicle using hydrogen, an engine system including an engine and configured for generating power of the vehicle using hydrogen, an exhaust system that purifies exhaust gas discharged from the engine, and a hydrogen supply system connected to the fuel cell system, the engine system and the exhaust system, and configured for supplying the hydrogen used in the fuel cell system and the engine system, and ammonia (NH3) used in the exhaust system.

A method monitors a pressure tank system of a stationary vehicle. The method detects a wake-up situation by use of sensor data of a main sensor of the vehicle. Furthermore, in reaction to the detection of a wake-up situation, the method activates a further resource for detecting and/or for evaluating sensor data with regard to the pressure tank system. Moreover, the method determines, by use of the further resource, whether one or more protective measures are to be carried out in relation to the pressure tank system and/or the surroundings thereof.

The invention relates to a tank device (24) for storing compressed fluids, in particular hydrogen, comprising at least one tank container (26) and a sensor module arrangement (100), wherein the sensor module arrangement (100) has a high-pressure sensor module (28). The sensor module arrangement (100) further comprises a low pressure sensor module (1), which low pressure sensor module (1) cooperates with a pressure regulating valve (44).

A hydrogen tank storage case that stores a hydrogen tank and that is loaded on a moving object includes: a housing having a box shape and having a side wall, a bottom, and a lid. The bottom and the lid have a communication portion configured to allow communication between the inside and outside of the housing. A flow resistance of the lid is lower than a flow resistance of the bottom.

In a fuel cell vehicle, an occupant room is disposed at a front part of a vehicle body frame, and a rear side of the occupant room of the vehicle body frame is a load mount part. A hydrogen handling device is supported at least by the load mount part. The fuel cell vehicle includes a cover room that surrounds at least an upper part and a side part of the hydrogen handling device that is supported by the load mount part. A load room is disposed on the load mount part of the vehicle body frame. A discharge duct that discharges a hydrogen gas in the cover room upward from between the load room and the occupant room is connected to the cover room.

The present invention relates to a modular vehicle system and assembly thereof comprising a preassembled Body (Cabin Module) and a preassembled Chassis (Drive Module). More particularly, the present invention relates to the modular vehicle system allowing for the docking of a Cabin Module onto a Drive Module, and wherein Drive Modules can be seamlessly interchanged during the lifespan of the Cabin Module.

A method for producing a compressed gas tank for a motor vehicle includes inserting a bundle of heat-conducting elements through an opening in a housing of the compressed gas tank and exerting a force on the bundle that radially expands the bundle within the housing beyond the size of the opening. The heat-conducting elements may be helically wound about a central axis when inserted through the opening with a torsional force applied to unwind the elements while radially expanding and reducing axial length of the bundle. A compressed gas tank for a motor vehicle includes a plurality of heat-conducting elements including at least one tube within a tank housing that extend axially along the tank and radially within the housing to a size exceeding an opening of the housing. The tube is configured to circulate coolant to cool compressed gas within the tank.

A tank for containing pressurized hydrogen for a fuel cell vehicle, comprising at least one fuel tank comprising a wall configured to delimit an internal volume for containing said pressurized hydrogen, said tank comprising safety means configured to chemically neutralize said pressurized hydrogen according to a pre-established condition.
