Energy Management Strategy and Parametric Design for Fuel Cell Family Sedan 2003-01-1147

In this paper, the practical configuration of power train for fuel cell family sedan (FCFS) is introduced. Based on the analysis of the operation modes, the energy management strategy has been developed, which can operate the fuel cell and motor within its highly efficient range as much as possible and keep the battery state of charge (SOC) at reasonable level. The parameters of the power unit (included fuel cell, motor, battery, transmission) are calculated and discussed in details according to the vehicle requirements for maximum cruising speed, acceleration time, grade ability, and fuel efficiency. The simulation results show that, this family sedan would have comparable performance with corresponding conventional one, much better fuel economy, and a unlimited range by the battery storage energy.
