Study on the Control Strategy for a Fuel Cell Hybrid Vehicle

A new control strategy for a fuel cell-oriented hybrid electric vehicle is proposed. The fuel cell hybrid electric vehicle power train is built up and control-limitation model for the high-pressure fuel cell engine is set up. Seven working modes are established and the control logic to realize the fuel cell as the primary power source and maintain the SOC of battery pack is constructed. Experimental results indicated that the fuel cell power can follow the driver's requirements very well. The hybrid vehicle's hydrogen consumption is up to 2.464 kg/100 km.
