11. Simulation Analysis and Research of C70GB Fuel Cell Vehicle

Due to long endurance mileage and short fueling time, fuel cell vehicle had became the main development direction of range extend electric vehicle. In order to improve the service life and tech-characteristics, many departments carried out research related to the fuel cell and control system of fuel cell vehicle. In this study, the power systems, fuel cell systems, power battery systems and other simulation systems were constructed and tested for C70GB model, and calculate the power, energy consumption and other aspects of the calculation. The simulation results show that the fuel cell can effectively improve the energy power battery vehicle system dynamic and climbing performance, equipped with two 70 MPa cylinders can effectively extend the mileage of the vehicle, and ensure daily using demand.
