Value Unit Vehicle glider mass, m Gravity, g Rolling resistance coefficient, f, Transmission efficiency, n Air density, pa Aerodynamic drag coefficient, Ca Frontal area, Af Wheel radius Average electrical accessory load Vehicle cargo mass Electric motor mass Fuel cell system mass 592 9.81 0.009 0.92 1.2 0.335 2.0 0.282 700 136 91 223 kg m/s 1 - kg/m m W kg kg kg Determine the base power provided by the fuel cell system if the cruise speed is 60km/hr. Make suitable assumptions for transmission and motor efficiency b. If the vehicle has to accelerate to 60km/hr in 40s, determine the total electric power required by the vehicle c. It is proposed to have either a battery or ultracapacitor for this hybrid system. Design these sources to provide the dynamic power. Determine the battery module and capacitor bank module's specifications (no. of cells) Compare and write your conclusions. The specifications for the battery and ultracapacitor are given below.
