Abstract
A pressure vessel system has a pressure vessel for storing gaseous fuel, a fuel line, and a total-pressure sensor for measuring a total pressure of the fuel at a position within the fuel line. This makes it possible for various functions, such as the control of power reduction, for example, to be performed more accurately than if only static pressure were being used. The technology disclosed here also relates to an energy supply arrangement having such a pressure vessel system and having an energy converter, such as a fuel cell, for example.
Claims20
A pressure vessel system in a motor vehicle, the pressure vessel system comprising:
- a pressure vessel in the motor vehicle for storing gaseous fuel;
- a fuel line connected to the pressure vessel;
- a total-pressure sensor connected to the fuel line for measuring a total pressure of the gaseous fuel at a position within the fuel line, wherein
- the total-pressure sensor is configured to measure the total pressure in both directions of flow, the total-pressure sensor being rotatably connected to the fuel line,
- the total-pressure sensor is rotatably designed, so that an inlet opening can be kept in both directions of flow, and
- the total-pressure sensor is configured to measure the total pressure when the gaseous fuel is flowing away from and toward the pressure vessel.
A method of measuring pressure in a fuel line of an energy supply arrangement in a motor vehicle, the method comprising:
- providing in the motor vehicle a pressure vessel containing a gaseous fuel, an energy converter connected to the pressure vessel by a fuel line, and a total-pressure sensor connected to the fuel line;
- flowing the gaseous fuel through the fuel line;
- and
- measuring a total-pressure using the total-pressure sensor, wherein
- the total-pressure sensor is rotatably connected to the fuel line, and thereby configured to measure the total pressure in both directions of flow,
- the total-pressure sensor is rotatably designed, so that an inlet opening can be kept in both directions of flow, and
- the total-pressure sensor is configured to measure the total pressure when the gaseous fuel is flowing away from and toward the pressure vessel.
