Abstract :
A comprehensive performance analysis is crucial for advance a system to a practical level. This paper presents the performance analysis of energy regeneration system (ERS) of electric vehicle (EV) with two wheels under the model of constant braking torque (CBT). For this, a boost equivalent circuit for main power case (MPC) of ERS is obtained firstly, and then a large signal time domain average model of MPC, which constitutes the complete model of ERS along with the other three parts: system dynamics model, permanent dc motor driving system model and system performance calculation model, is given here. During modeling ERS, a new method based on state forecast viewer is proposed to identify the state (CCM or DCM) of the MPC. As a nonlinear system, the large signal time domain model of ERS can´t be transferred to frequency domain model and implemented in MATLAB/Simulink directly, a method of dividing the system into a slow variable system and a fast variable system is introduced. By running this simulation model, several important performances of ERS are obtained efficiently.
