Dynamic power regulation system for vehicle electric drive unit - regulates power output delivered by fuel cell using correction of oxidant mass flow rate

摘要

The regulation system is used for an electric drive unit (17) supplied from a fuel cell (1) on board the vehicle, the power obtained from the fuel cell adjusted by regulating the oxidant mass flow rate. Pref. a required power signal is supplied in dependence on the depression of the vehicle accelerator pedal, the corresponding mass flow rate compared with the actual mass flow rate via a regulating circuit, for correcting the detected difference between them. ADVANTAGE - Provides optimal utilisation of available electrical power.
