Controlling energy supply of mobile device with electric drive motor(s) and hybrid energy supply system involves deriving difference between fuel cell system and storage battery power components

摘要

The method involves processing power demand, mode selection, fuel cell current and voltage sensor and mobile device speed signals to determine power components from the fuel cell and dynamic energy systems and deriving the difference between the fuel cell system power component and the desired power from storage batteries of the dynamic energy system by subjecting a direct current to direct current converter to suitable demand values. The method involves processing a power demand signal, a mode selection signal, fuel cell current and voltage sensor signals and mobile device speed signals to determine the power components from the fuel cell system (7) and dynamic energy system and deriving the difference between the power component generated by the fuel cell system with a delay according to the transfer function and the desired power from storage batteries of the dynamic energy system obtained by subjecting a direct current to direct current converter (9) to suitable demand values. An Independent claim is also included for an arrangement for controlling the energy supply of a mobile device with at least one electric drive motor and a hybrid energy supply system with a fuel cell system and a dynamic energy supply system.
