System for controlling power distribution of fuel cell-hybrid electric vehicle has controller that selectively controls modes according to instantaneous required vehicle power and battery charge state

摘要

The system has a bidirectional DC/DC converter (30) connected to the battery, an inverter (40) connected to the converter and fuel cell (10), a vehicle drive motor (50) and a controller (300) that selectively controls a number of modes according to the instantaneous required vehicle power and a battery charge state, including a fuel cell mode in which the fuel cell energy is transferred via the inverter to drive the motor. An Independent claim is also included for a method of controlling the power distribution of a fuel cell-hybrid electric vehicle.
