This paper presents the modeling and performance analysis of energy regeneration system (ERS) of electric vehicle with permanent magnet DC motor driving system. Based on the boost equivalent circuit with average current mode controlled ERS, a detailed switching model (DSM) is built to predict the dynamical performance. The DSM includes four blocks: system dynamics block, permanent magnet DC motor block, boost converter block and system performance calculation block. An automatic mechanism of linearizing the nonlinear system at the local operating point is enrolled to obtain the small signal average model (SSAM) of ERS, by which the frequency domain performance can be acquired. The proposed models are implemented in MATLAB/Simulink. By running the simulation model, several important performances of ERS are obtained.
