Abstract
The invention relates to a method for operating a fuel cell system, wherein the fuel cell system is controlled in accordance with a system-specific digital twin (14) that represents the fuel cell system. According to the invention, the digital twin (14) controls the fuel cell system in at least two different active operating states (16, 18) of the fuel cell system.
Claims19
A method for operating a fuel cell system, the method comprising:
- providing, with a computing unit of the fuel cell system, a system-specific digital twin (14) that maps the fuel cell system,
- determining, with the digital twin (14), that the fuel cell system is in one of at least two different active operating states (16, 18) of the fuel cell system based on a sensed parameter sensed by a sensor of the fuel cell system,
- mapping, with the digital twin, the fuel cell system using a first model corresponding to a first active operating state,
- comparing, with the digital twin, a value from the first model to the sensed parameter, and
- providing, based on the comparison and with the digital twin, operating parameters to a control unit of the fuel cell system to control the fuel cell system,
- wherein the digital twin reduces a computational effort to map the fuel cell system when the fuel cell system switches from the first active operating state to a second active operating state by deactivating at least one computational module of the digital twin.
