VEHICLE-ELECTRICAL-SYSTEM ASSEMBLY AND METHOD FOR OPERATING A VEHICLE ELECTRICAL SYSTEM OF AN ELECTRICALLY DRIVABLE MEANS OF TRANSPORTATION HAVING A FUEL CELL
First Claim
1. A method for operating an electrically driven transportation vehicle electrical system, the method comprising:
- ascertaining a current electrical power consumption of a traction machine of the electrically driven transportation vehicle with dynamic power consumption behavior at a first time;
providing a base value by smoothing the power consumption behavior over time;
defining a power reserve for the component by adding a static power offset to the base value; and
limiting a vehicle electrical system power available for the traction machine of the electrically driven transportation vehicle for providing the defined power reserve.

Abstract
A vehicle-electrical-system assembly and a method for operating a vehicle electrical system of an electrically drivable transportation unit. The method includes determining a present electrical power consumption of a component having dynamic power-consumption behavior at a first time, providing a base value by smoothing the power-consumption behavior over time, defining a power reserve for the component by adding a static power offset to the base value, and limiting a vehicle-electrical-system power available for a traction machine of the transportation unit to provide the defined power reserve for the component.
