Modular range extender system of electric drive motor vehicle and electric drive motor vehicle with range extender

摘要

The present invention relates to a modular range extender system (20) of an electric drive motor vehicle (52), comprising a plurality of fuel advances connected in series and interfaces for supplying hydrogen and air and for discharging water and residual gas, respectively. having a plurality of fuel cell basic modules 10; and a medium supply device designed to supply air and hydrogen to the fuel cell basic modules 10 through the interfaces and discharge water and residual gas from the fuel cell basic modules 10 through the interfaces, wherein different outputs and Different numbers of fuel cell base modules 10 are electrically connectable to each other in different series and/or parallel circuits to provide voltage and/or media supply to form different variants of range extender 22 . Configurable. The invention also relates to a circuit arrangement 40 of a vehicle electrical system of an electric drive motor vehicle 52 and to an electric drive motor vehicle having a circuit arrangement 40 of this kind.
