Abstract
The purpose of this study is to analyze and to design for the hybrid power systems with variable inertia flywheel while the hybrid power system consists of 1 power plant, 1 variable inertia flywheel which is used as the energy storage device, a planetary gear set, and a set of actuators. First, the kinematic and kinetic equations of the hybrid power system are developed in order to establish the relationships of the speed and torque of all elements, and the specific speed and torque of the output needed for the vehicle can be found by using the software "ADVISOR" in various operation modes. Then, with the prescribed mechanical brake energy recovery system model and a control model, a comprehensive analysis can be achieved. Finally, various driving modes, such as ECE, ECE+EUDC and New York Bus driving mode are investigated in order to demonstrate the characteristics of the hybrid power system. The numerical results show and conclude the effectiveness of the variable inertia flywheel, and the improvement on the efficiency of hybrid power systems. Copyright Form of EVS25. © 2010 WEVA.
