A tank filler neck including a filling line having an insertion end further away from the tank, designed to temporarily insert a breather pipe into the end region of the filling line further away from the tank, a passage line end closer to the tank, designed for passing through liquid in the direction away from the insertion end, a ventilation volume designed for through-flowing gas while passing liquid through the end of the passage line, a ventilation line which ends at a distance from the filling line and which can be blocked or released by a ventilation valve for through-flowing gas, a detecting device designed to detect a passage-ready state and/or a passage state of the filling line, and an operating device designed to adjust, as a function of the detection result of the detecting device, the ventilation valve between the blocking position and the release position.

A fuel system for installation in a hydrogen-powered vehicle and for one or more hydrogen pressure tanks configured for a high pressure level of at least 200 bar, includes connections for input and output lines and at least the following internal components: a pressure reducer, a gas filter, a shut-off valve, a vent valve, an overpressure safety valve and a pressure sensor. The pressure reducer is a two-stage pressure reducer which reduces the pressure of the hydrogen from the high pressure level from the pressure tank to a medium pressure level between 3 bar and 30 bar. The first stage reduces the pressure from the pressure tank to an intermediate level between 40 and 80 bar and the second stage further reduces the pressure to the medium pressure level. The internal components and gas lines interconnecting these internal components are disposed in an integral and self-supporting modular unit.

A vehicle has a fuel system that includes a controller that determines when the vehicle is in a refuel mode or a run mode based on a connection of a refuel nozzle to a vehicle connection of the vehicle. The controller controls a fuel pump input selector, a vehicle fuel pump, and a fill/run fuel selector such that fuel is pumped from a storage tank external to the vehicle into a vehicle fuel tank by way of the vehicle fuel pump in the refuel mode, and fuel is pumped to an engine of the vehicle from the vehicle fuel tank by way of the vehicle fuel pump in the run mode.

Methods, apparatus, and computer readable media are disclosed for deterrence of ignition of a vehicle engine ignition when a fuel nozzle is in a fuel intake area. An example vehicle includes a fuel intake area, a camera, and a processor. The example processor, in response to an ignition switch being in an on-position, is to detect, via the camera, whether a fuel nozzle is in the fuel intake area. The example processor is to deter ignition of a vehicle engine when the fuel nozzle is in the fuel intake area.

A hydrogen-powered vehicle has a frame; a driver cab mounted on the frame; a first drive wheel and a second drive wheel, which are configured to move the vehicle forward in a travel direction. The hydrogen-powered vehicle also has a hydrogen accumulator comprising a plurality of supply tanks, which are configured to contain hydrogen, and a housing structure, which houses the supply tanks and is coupled to the frame in a movable manner between a lowered position and a raised position.

A method for controlling an access panel to a recharging device of a motor vehicle powered by an electric and/or heat engine and including a sensor for detecting an external environment of the vehicle, a system for detecting a badge worn by a user and a sensor configured to detect whether the engine of the vehicle is switched off. In the method, data are recovered, the system for detecting a badge worn by the user and the sensor configured to detect whether the engine of the motor vehicle is switched off, when the vehicle is stationary and the badge is detected by the badge detection system, the sensor for detecting the external environment of the vehicle and a system for recognizing a charger of the recharging device are activated, and when the charger is detected, the panel is automatically opened in a position allowing access to the recharging device.
